對生成式 AI 的實用性表示懷疑,並要求提供實際證據證明其有效性。 | Expressing skepticism about the usefulness of generative AI and demanding practical evidence of its effectiveness.

I’d love to see the authors of effusive praise of generative AI like this provide the proof of the unlimited powers of their tools in code. If GAI (or agents, or whatever comes next …) is so effective it should be quite simple to prove that by creating an AI only company and in short order producing huge amounts of serviceable code to do useful things. So far I’ve seen no sign of this, and the best use case seems to be generating text or artwork which fools humans into thinking it has coherent meaning as our minds love to fill gaps and spot patterns even where there are none. It’s also pretty good at reproducing things it has seen with variations -that can be useful.

So far in my experience watching small to medium sized companies try to use it for real work, it has been occasionally useful for exploring apis, odd bits of knowledge etc, but overall wasted more time than it has saved. I see very few signs of progress.
The time has come for llm users to put up or shut up - if it’s so great, stop telling us and show and use the code it generated on its own.

Yeah exactly.

Whats nuts is watching all these people shill for something that we all have used to mediocre results. Obviously Fly.io benefits if people start hosting tons of slopped together AI projects on their platform.
Its kinda sad to watch what I thought was a good company shill for AI. Even if they are not directly getting money from some PR contract.
We must not be prompting hard enough....

生成式 AI 在處理低複雜度任務時非常有用,但在高複雜度任務中則效果有限。 | Generative AI is useful for low-complexity tasks but has limited effectiveness for high-complexity tasks.

I think we're talking past each other. There's always been a threshold: above it, code changes are worth the effort; below it, they sit in backlog purgatory. AI tools so far seem to lower implementation costs, moving the threshold down so more backlog items become viable. The "5x productivity" crowd is excited about this expanded scope, while skeptics correctly note the highest value work hasn't fundamentally changed.

I think what's happening is two groups using "productivity" to mean completely different things: "I can implement 5x more code changes" vs "I generate 5x more business value." Both experiences are real, but they're not the same thing.

This is exactly what I’ve experienced. For the top-end high-complexity work I’m responsible for, it often takes a lot more effort and research to write a granular, comprehensive product spec for the LLM than it does to just jump in and do it myself.

On the flip side, it has allowed me to accomplish many lower-complexity backlog projects that I just wouldn’t have even attempted before. It expands productivity on the low end.
I’ve also used it many times to take on quality-of-life tasks that just would have been skipped before (like wrapping utility scripts in a helpful, documented command-line tool).

擔憂過度依賴 AI 可能會阻礙新手程式設計師發展必要的專業技能。 | Concerns that over-reliance on AI may hinder the development of necessary expertise in novice programmers.

Question: If everyone uses AI to code, how does someone become an expert capable of carefully reading and understanding code and acting as an editor to an AI?

The expert skills needed to be an editor -- reading code, understanding its implications, knowing what approaches are likely to cause problems, recognizing patterns that can be refactored, knowing where likely problems lie and how to test them, holding a complex codebase in memory and knowing where to find things -- currently come from long experience writing code.
But a novice who outsources their thinking to an LLM or an agent (or both) will never develop those skills on their own. So where will the experts come from?
I think of this because of my job as a professor; many of the homework assignments we use to develop thinking skills are now obsolete because LLMs can do them, permitting the students to pass without thinking. Perhaps there is another way to develop the skills, but I don't know what it is, and in the mean time I'm not sure how novices will learn to become experts.

capnrefsmmat | source

It’s a great point and one I’ve wondered myself.

Arguments are made consistently about how this can replace interns or juniors directly. Others say LLMs can help them learn to code.
Maybe, but not on your codebase or product and not with a seniors knowledge of pitfalls.
I wonder if this will be programmings iPhone moment where we start seeing a lack of deep knowledge needed to troubleshoot. I can tell you that we’re already seeing a glut of security issues being explained by devs as “I asked copilot if it was secure and it said it was fine so I committed it”.

對 LLM 在語音辨識和翻譯等領域的進步表示讚賞,認為它們正在實現科幻小說中的承諾。 | Appreciation for the advancements of LLMs in areas like speech recognition and translation, seeing them as fulfilling promises from science fiction.

Yes, yes and yes!

I tried speech recognition many times over the years (Dragon, etc). Initially they all were "Wow!", but they simply were not good enough to use. 95% accuracy is not good enough.
Now I use Whisper to record my voice, and have it get passed to an LLM for cleanup. The LLM contribution is what finally made this feasible.
It's not perfect. I still have to correct things. But only about a tenth of the time I used to. When I'm transcribing notes for myself, I'm at the point I don't even bother verifying the output. Small errors are OK for my own notes.

BeetleB | source

I completely agree that technology in the last couple years has genuinely been fulfilling the promise established in my childhood sci-fi.

The other day, alone in a city I'd never been to before, I snapped a photo of a bistro's daily specials hand-written on a blackboard in Chinese, copied the text right out of the photo, translated it into English, learned how to pronounce the menu item I wanted, and ordered some dinner.
Two years ago this story would have been: notice the special board, realize I don't quite understand all the characters well enough to choose or order, and turn wistfully to the menu to hopefully find something familiar instead. Or skip the bistro and grab a pre-packaged sandwich at a convenience store.

使用 AI 生成程式碼可能導致對程式碼庫的熟悉度降低,並影響長期維護和理解。 | Using AI to generate code may lead to reduced familiarity with the codebase, impacting long-term maintenance and understanding.

I have one very specific retort to the 'you are still responsible' point. High school kids write lots of notes. The notes frequently never get read, but the performance is worse without them: the act of writing them embeds them into your head. I allegedly know how to use a debugger, but I haven't in years: but for a number I could count on my fingers, nearly every bug report I have gotten I know exactly down to the line of code where it comes from, because I wrote it or something next to it (or can immediately ask someone who probably did). You don't get that with AI. The codebase is always new. Everything must be investigated carefully. When stuff slips through code review, even if it is a mistake you might have made, you would remember that you made it. When humans do not do the work, humans do not accrue the experience. (This may still be a good tradeoff, I haven't run any numbers. But it's not such an obvious tradeoff as TFA implies.)

pie_flavor | source

Understanding code takes more effort than writing it, somehow. That's always been a huge problem in the industry, because code you wrote five years ago was written by someone else, but AI coding takes that from "all code in your org except the code you wrote in the past couple years" to "all code was written by someone else".

How well does your team work when you can't even answer a simple question about your system because nobody wrote, tested, played with the code in question?
How do you answer "Is it possible for our system to support split payments?" when not a single member of your team has even worked on the billing code?
No, code reviews do not familiarize an average dev to the level of understanding the code in question.

強調學習和適應 LLM 工具的重要性,認為無法有效利用這些工具的程式設計師將會落後。 | Emphasizing the importance of learning and adapting to LLM tools, suggesting that programmers who fail to effectively use them will be left behind.

“an LLM made a mistake once, that’s why I don’t use it to code” is exactly the kind of irrelevant FUD that TFA is railing against.

Anyone not learning to use these tools well (and cope with and work around their limitations) is going to be left in the dust in months, perhaps weeks. It’s insane how much utility they have.

sneak | source

The important thing you are missing is that the learning landscape has now changed.

You are now responsible for learning how to use LLMs well. If an untrained vibe coder is more productive for me, while knowing nothing about how the code actually works, I will hire the vibe coder instead of you.
Learning is important, but it's most important that you learn how to use the best tools available so you can be productive. LLMs are not going away and they will only get better, so today that means you are responsible for learning how to use them, and that is already more important for most many roles than learning how to code yourself.

對使用自然語言與電腦互動表示擔憂,強調精確指令和形式語言在程式設計中的重要性。 | Expressing concern about using natural language to interact with computers, emphasizing the importance of precise instructions and formal languages in programming.

>simple fact that you can now be fuzzy with the input you give a computer, and get something meaningful in return

I got into this profession precisely because I wanted to give precise instructions to a machine and get exactly what I want. Worth reading Dijkstra, who anticipated this, and the foolishness of it, half a century ago
"Instead of regarding the obligation to use formal symbols as a burden, we should regard the convenience of using them as a privilege: thanks to them, school children can learn to do what in earlier days only genius could achieve. (This was evidently not understood by the author that wrote —in 1977— in the preface of a technical report that "even the standard symbols used for logical connectives have been avoided for the sake of clarity". The occurrence of that sentence suggests that the author's misunderstanding is not confined to him alone.) When all is said and told, the "naturalness" with which we use our native tongues boils down to the ease with which we can use them for making statements the nonsense of which is not obvious.[...]
It may be illuminating to try to imagine what would have happened if, right from the start our native tongue would have been the only vehicle for the input into and the output from our information processing equipment. My considered guess is that history would, in a sense, have repeated itself, and that computer science would consist mainly of the indeed black art how to bootstrap from there to a sufficiently well-defined formal system. We would need all the intellect in the world to get the interface narrow enough to be usable"
Welcome to prompt engineering and vibe coding in 2025, where you have to argue with your computer to produce a formal language, that we invented in the first place so as to not have to argue in imprecise language

Barrin92 | source

right: we don't use programming languages instead of natural language simply to make it hard. For the same reason, we use a restricted dialect of natural language when writing math proofs -- using constrained languages reduces ambiguity and provides guardrails for understanding. It gives us some hope of understanding the behavior of systems and having confidence in their outputs

There are levels of this though -- there are few instances where you actually need formal correctness. For most software, the stakes just aren't that high, all you need is predictable behavior in the "happy path", and to be within some forgiving neighborhood of "correct".
That said, those championing AI have done a very poor job at communicating the value of constrained languages, instead preferring to parrot this (decades and decades and decades old) dream of "specify systems in natural language"

強調使用 LLM 進行程式設計時的安全和隱私風險,包括程式碼洩漏和智慧財產權問題。 | Highlighting the security and privacy risks of using LLMs for programming, including code leaks and intellectual property concerns.

One of the biggest anti LLM arguments for me at the moments is about security. In case you don't know, if you open a file with copilot active or cursor, containing secrets, it might be sent to a server a thus get leaked. The companies say that if that file is in a cursorignore file, it won't be indexed, but it's still a critical security issue IMO. We all know what happened with the "smart home assistants" like Alexa.

Sure, there might be a way to change your workflow and never ever open a secret file with those editors, but my point is that a software that sends your data without your consent, and without giving you the tools to audit it, is a no go for many companies, including mine.

LLM 技術快速發展,需要持續學習和更新知識,但同時也讓人們對不斷變化的炒作週期感到疲倦。 | The rapid pace of LLM technology requires continuous learning and knowledge updates, but also causes fatigue with the ever-changing hype cycles.

>If you were trying and failing to use an LLM for code 6 months ago †, you’re not doing what most serious LLM-assisted coders are doing.

Here’s the thing from the skeptic perspective: This statement keeps getting made on a rolling basis. 6 months ago if I wasn’t using the life-changing, newest LLM at the time, I was also doing it wrong and being a luddite.
It creates a never ending treadmill of boy-who-cried-LLM. Why should I believe anything outlined in the article is transformative now when all the same vague claims about productivity increases were being made about the LLMs from 6 months ago which we now all agree are bad?
I don’t really know what would actually unseat this epistemic prior at this point for me.
In six months, I predict the author will again think the LLM products of 6 month ago (now) were actually not very useful and didn’t live up to the hype.

davidclark | source

The most important thing in this article in my mind is in the level setting section - if you are basing your perspective on the state of AI from when you tested it 6mo+ ago, your perspective is likely not based on the current reality.

This is kind of a first though for any kind of technology. The speed of development and change here is unreal. Never before has a couple months of not being on top of things led to you being considered "out of date" on a tool. The problem is that this kind of speed requires not just context, but a cultural shift on the speed of updating that context. Humanity just isn't equipped to handle this rate of change.
Historically in tech, we'd often scoff at the lifecycle of other industries - Airlines haven't changed their software in 20 years?? Preposterous! For the vast majority of us though, we're the other industry now.

認為專業知識是不好的,並應擁抱能使專業知識在經濟上變得無關緊要的技術變革。 | Believing that expertise is a bad thing and that technological changes that render expertise economically irrelevant should be embraced.

I'll take the opposite view of most people. Expertise is a bad thing. We should embrace technological changes that render expertise economically irrelevant with open arms.

Take a domain like US taxation. You can certainly become an expert in that, and many people do. Is it a good thing that US taxes are so complicated that we have a market demand for thousands of such experts? Most people would say no.
Don't get my wronf, I've been coding for more years of being alive than I haven't by this point, I love the craft. I still think younger me would have far preferred a world where he could have just had GPT do it all for him so he didn't need to spend his lunch hours poring over the finer points of e.g. Python iterators.

認為 LLM 的進步停滯不前,並且模型已經達到了其能力的極限。 | Believing that LLM progress has stalled and that models have already reached the limits of their capabilities.

Models are absolutely not improving linearly. They improve logarithmically with size, and we've already just about hit the limits of compute without becoming totally unreasonable from a space/money/power/etc standpoint.

We can use little tricks here and there to try to make them better, but fundamentally they're about as good as they're ever going to get. And none of their shortcomings are growing pains - they're fundamental to the way an LLM operates.

認為智慧型手機對人類來說是一個巨大的負面影響。 | Believing that smartphones are a huge negative to humanity.

I still think smartphones are a huge negative to humanity. They improve a narrow case: having access to ephemeral knowledge. Nobody writes articles or does deep knowledge work with smartphones.

My position with the AI is almost the same. It is overall a net negative for cognitive abilities of people. Moreover I do think all AI companies need to pay fair licensing cost to all authors and train their models to accurately cite the sources. If they want more data for free, they need to propose copyright changes retroactively invalidating everything older than 50 years and also do the legwork for limiting software IP to 5 to 10 years.

You've already lost me, because I view programming as an art form. I would no more use AI to generate code than I would use it to paint my canvas.
I think the rest of the article is informative. It made me want to try some things. But it's written from the perspective of a CEO thinking all his developers are just salt miners; miners go into the cave and code comes out.
I think that's actually what my hangup is. It's the old adage of programmers simply "copying and pasting from stack overflow" but taken to the extreme. It's the reduction of my art into mindless labor.

對 MongoDB 的負面評價,認為其品質低劣,並將其與 AI 產生的內容相提並論 | Negative evaluation of MongoDB, considering it of poor quality and comparing it to AI-generated content.

There's a paragraph that literally starts with "system."

> system. It's too complex and detailed, so it's not much easier to understand than the implementation code, and state-space explosion dooms model checking. The author abandons the spec and concludes that TLA+ is impractical. In the eXtreme Modelling style, a big system is modeled by a collection of small specs, each focusing on an aspect of the whole. This was the direction MongoDB was already going, and it seemed right to me.
This reads like AI generated slop. Which is actually on brand, because Mongo is slop.

Phrasing.app | CTO | EU Remote

I've spent the last 18 months iterating on Phrasing, a language learning app for polyglots. It's finally reached a stable point, and we're starting to get Daily Active Users. I've been using it every day for over a month now to learn over a dozen languages, and have been blown away at my progress.
However, I've really reached the limit of what one engineer can do alone. I'm looking for someone to help me make it go brrr. Someone who would love to iterate on our in-house sync engine, make our monolithic postgres database purr, and wouldn't be scared of a little machine learning.
The product is built in Elixir on the backend, ClojureScript on the front-end. There are no experience requirements so long as you're committed, capable, and hungry.
I'm really trying to do something different with Phrasing. No investors, no hyper-scaling, no enshittification - just a relentless pursuit of mastery and a delightful product.
If any of this is speaking to you, get in touch at hackers [at] phrasing [dot] app.

大量未使用的 CSS class 名稱可能會對瀏覽器的快取造成影響,但需要進行測試才能確定。 | A ton of unused class names could explode the cache of browsers, but it requires some testing to know.

I would double check that this doesn't have performance implications before going wild. Those are extra tokens that need to be parsed, and browsers do a lot of work to speed up selector matching, including building caches of class names to nodes.

It could be that browsers populate these caches even for unused class names because it's difficult to know at that point in time whether a class name is used or will be used in the future. A ton of unused class names could explode the cache, evict important classes... who knows?
It could also be that the cache is built on demand as selectors are matched and having a ton of unused classes doesn't matter at all.
The point is that it's quite implementation dependent and requires some testing to know. To be safe, I'd just stick to comments because they are very, very cheap, in all browsers and parsers.

9. CVE 2025 31200
todsacerdoti | 79 points | 21 comments | read
Common Themes
對於音訊格式漏洞的擔憂以及隔離處理器的必要性。 | Concerns about audio format vulnerabilities and the need for isolated processors.

> Essentially, if you have a vector, say [A,B,C] that you actually want to be [B,A,C], then you might do that with a ‘permutation map’: another vector that says where each element should go. In this case that would be [1,0,2], which means that the element at index 1 should go to index 0, and the element at index 0 should go to index 1 and the element at index 2 should stay where it is. The simplest working way to do this is to just allocate another vector, and essentially use the permutation map as a kind of dictionary (index→element) for populating that third vector. However, if you would rather be clever and don’t feel like allocating a whole other vector, then you can use the algorithm above.

This isn't being clever, it's actually incorrect to allocate a whole other vector. Realtime code requires O(1) memory complexity for correctness. Although the smart thing would be to preallocate a buffer for the pointers, but in general that may not be possible (I'm not an expert in CoreAudio but if the channels are interleaved and the next chunk of code expects to process in place you really do have to it this way).
It sounds like the CVE is super simple, reduced to:
- CoreAudio determines the number of channels before playback to create a resource, standard practice in audio processing
- It then trusts the number of channels of an incoming stream when using that resource
- A maliciously crafted audio file can bypass checks for this and trigger a buffer overflow
Never trust your inputs, folks.
The reason this comes up with HOA to me is not surprising: almost no one uses HOA, and a variety of other optimizations like assuming the "H" in HOA only refers to up to 128 channels (since afaik, no one even tries past that point).
> Imagine if the primitive is that you can write n 8 byte sequences out of bounds, but they must be valid 32 bit floats in the range x-y
I imagine the only thing you need to guarantee is you don't use subnormals, since audio code usually enables FTZ mode on both ARM and x86.

duped | source

I’d be really frustrated if my device was compromised by an esoteric audio format that I had no intention of ever listening to.

If these parsers can’t run inside an isolated process, perhaps they shouldn’t be enabled at all?

許多人使用非傳統的打字方式,並且對是否應該學習正確的「home row」打字方式表示懷疑。 | Many people use non-traditional typing methods and express skepticism about whether they should learn the "home row" typing method.

I used to type >140 WPM at high accuracy when I was younger without home row. These days I think I likely sit closer to 90 WPM or so, since I really just don't really need to type super fast very often and am pretty out of practice. I reckon home row is probably not terrible or anything, but like a lot of weird old ergonomics advice, I just don't trust the idea that you must or possibly even should use home row. For example, the best advice regarding ergonomics I've ever had is not to have proper posture at all times, but rather to get up more frequently and not sit in the same position for too long. Likewise, it feels a lot more natural to let my hands move around a bit, and as it would turn out my mouse arm is the one that wound up having more discomfort from long term computer usage. So clearly, YMMV. But a lot of us who didn't do home row are confused; some people will go as far as to say it's literally wrong not to, and I say, burden of proof is on you all.

> Plot twist: I don't type "correctly" at all. My fingers just go wherever they want. It's like anarchist typing. My left pinky probably hasn't touched the 'A' key in months, but somehow I'm still in the 99.5 percentile. Turns out the "proper way" is just a suggestion. Like following PEP 8 or using semicolons in JavaScript. Sure, it's nice, but if your way works better, who cares?

This is super interesting - I have typed "wrong" since the time I first picked up a keyboard, 6 or 7 years old, back in an age where typing was not taught in school or an expected skill everyone was just automatically meant to know. As such, I developed my own "style" which looks a lot like "pecking" a lot of beginners will do, but has adapted over the decades to something that is my own.
I typically just use the index/middle finger on my left hand that covers most of the left hand side of the keyboard, depending on word (index might reach for the 'y' key sometimes) and the pinky for shift key. Right hand uses mostly the index, ring (for hitting backspace and enter) and thumb (for spacebar). I've often wondered if I was ever able to retrain myself to do it "properly" whether I'd type even faster than I do. now I am not sure.
I have "peaked" at 125+ wpm in 1 minute tests, and in casual conversation with familiar words, probably can maintain easily around 110-120. I think for most things I typically cruise around 100 without trying too much. It is a nice skill but I've never been able to figure out why I type so much faster than most people I meet, especially given being self-taught and the unorthodox way in which I type. Often when I am showing something on a terminal, for instance, which includes a lot of auto complete and muscle memory, I need to slow down by about 10-20x for people to follow what I am doing.

使用符合人體工學的鍵盤配置(ergonomic keyboard layout)和輕巧的鍵帽(keycaps)可以減少手腕疼痛,即使會稍微降低打字速度也是值得的。 | Using ergonomic keyboard layouts and lightweight keycaps can reduce wrist pain, even if it slightly reduces typing speed.

I started using an ortholinear split keyboard last year, and that was a huge adjustment. I went from typing 100+wpm on a simple membrane keyboard, to less than half of that. I had to basically relearn typing just to accomodate the ortholinear layout, not to mention that the split layout meant I could no longer "cheat" and use my right hand to type keys on the left side of the keyboard when I was feeling lazy.

I did learn the "right" way to type through all this, and my speedhas stabilized at around 100 wpm. This is more than enough for pretty much any activity I do on the computer.
More importantly, however, my wrists no longer hurt from typing continously for 30 minutes. The small sacrifice in speed is definitely worth it in my opinion.

ashwinsundar | source

Went through the same process last year due primarily to trying to find a solution to my cubital tunnel syndrome. I dropped down to like legit 20wpm from ~120wpm. I'm back to around 100 or so but a lot more comfortable and with less pain.

I recommend either the Kinesis Advantage 360 pro or the glove 80 to anybody who uses a keyboard a lot for a living. I tried both and frequently switch between them.
Another thing I recommend to people with problems is to get literally the lightest keycaps you can, and while it may slow you down a bit try to bottom out less/type a bit lighter in general.

線上遊戲和即時通訊(IRC, AIM)是提高打字速度的重要動力。 | Online games and instant messaging (IRC, AIM) were important drivers for improving typing speed.

I skipped typing classes altogether, and I'm not sure how; they were a requirement in every school district I attended and a prerequisite to the programming classes that I took instead.

Biopure was a company doing something similar in the US. They imploded in the early 2000s, but they had created an "oxygen therapeutic" (blood substitute) by isolating hemoglobin based oxygen carrying molecules FROM COW BLOOD!

The fact that they weren't using whole red blood cells meant the product was typeless, room temp stable, and better at perfusing around arterial blockages and into tissue since the molecules were so small.
Unfortunately, the company was kind of a mess. They managed to get licensed for sale in South Africa, and in the US for the veterinary product, but never managed FDA approval. It's a shame. Everyone could see the promise of the product, and it really actually worked, but they just couldn't seem to make the business viable.

Edit: When I say they imploded, I really mean it. They got prosecuted for misleading statements to investors about the state of US clinical trials, and the legal proceedings became farcical.
"On March 11, 2009 [Senior VP] Howard Richman pleaded guilty in U.S. District Court and admitted he had instructed his lawyers to tell a judge he was gravely ill with colon cancer.

Common Themes
協作功能是關鍵,現有工作流程存在痛點,Arcol 有潛力改善設計流程。 | Collaboration is a key feature, current workflows have pain points, and Arcol has the potential to improve the design process.

This looks amazing!

I'm working on a construction project right now (not as an architect/engineer) and I can tell you right now that live collaboration is THE killer feature (your slick UI not withstanding).
If this job is anything to go by, the current state-of-the-art appears to be a single Revit model file released once a month, 10,000 excel spreadsheets and 3,000 PDFs of various versions and quality spread between Sharepoint and a Document management server.
I'm sure you've got an amazing roadmap, but it would be great to see you apply a modern take on:
- how to handle version control in a multi-user environment (endless designing is fun, but at some point you need to draw a line in the sand so that people can start work, then changes need to be highlighted for the guy on the ground swinging a hammer)
- collaboration with 3rd-parties that may have a subset of design responsibilities (e.g. HVAC, electrical - they can place things in a room, but can't adjust the dimensions of a room)
- design reviews - current state-of-the-art seems to be marking up PDFs of DWGs with comments (which the supplier completely ignores on their next revision)
I look forward to watching this product evolve!
Small typo on your Love Letter to Designers post:
"A promise we will make at Arcol is tolisten first"

dfex | source

It coexists with Revit right now, and is a good place to do feasibility and early design and get instant metrics and feedback. We think it's a lot more collaborative and design friendly.

One day we'd love to take them on directly, I think there's a lot of architects out there looking for something better.
As far as collaboration features, we've built it from the ground up with collaboration in mind, so you can work with other users directly in the same scene and see their actions and updates. We've got collaborative presentation boards with views and metrics that can update live, and of course workflow features like commenting. And since it's browser based, there's not the friction of installing a desktop app, which can be significant at some orgs.
We'd love to know what you think though, give it a try and let us know what collaboration features you'd use!

As somebody outside of the industry, what's the final output of this product? I don't see doors, so I'm assuming this tool is intended to be used to rough out shapes and costs collaboratively? I totally see the utility in having a collaborative tool at those early stages. How far does Arcol go? Can it spit out blueprints?

itishappy | source

Exactly, at this stage, the output is mainly for feasibility, presentations and communication. But we can also export models to Revit or 3D formats like GLTF to use in the next steps of the process, or for renders, etc. But we're planning to continue to add features to make it useful further down the AEC pipelines.

Good point about the play button, I'll pass that feedback along. :)

Lottie 的適用性和與其他技術的比較 | Suitability of Lottie and comparison with other technologies.

This is the second time I've seen Lottie mentioned this week, without hearing about it before.

Maybe it's targeting a different use-case, but these things (at least on the Web) appear to be more-heavyweight and less-capable than the things people were doing 20 years ago with Macromedia/Adobe Flash, e.g. compare the animated-GIF-like examples linked from TFA ( https://thorvg-perf-test.vercel.app/ ) to the animations and games found on sites like Newgrounds. Last I checked, the latter make heavy use of emulators like Ruffle, or (based on loading screens) 3D game engines like Unity etc.
As someone who's been out of that scene for a long time: what's the overall state of things, if I want to make long, complex, 2D vector animations? (i.e. not using a 3D engine; and not rendering to video). SVG seems pretty established; but for animation, how capable is Lottie? Does anyone still use SMIL (outside of DVD menus)? Am I better off "rendering" to a big pile of JS + CSS transitions?

chriswarbo | source

Lottie is quickly becoming the de-facto standard for UI animations, but live, long running vector animations aren’t really something I’ve seen much of - at this point, video compresses well enough that people will simply use an mp4 or webp for that use case. I know that’s not what you’re looking for but since it isn’t a common use case, I haven’t seen much support for it. Lottie is perfectly capable for this use case, provided you don’t want audio.

SVG 軟體中漸層處理的局限性,以及對改進的期望 | Limitations in gradient handling in SVG software and expectations for improvement.

I find that gradient are really badly handled usually in svg softwares, I hope this can improve it.

In inkscape you can make only a one direction gradient, never a gradient with more than 2 points, I don't know if it is a limitation of the format itself.
Also when you have multiple gradients in one file, the software becomes extremely slow. And they don't mix correctly when overlapped with transparency.
It seems a low hanging fruit to optimize that, but I guess there is little traction

somethingsome | source

This is not supported in SVG. There was a Mesh Gradient feature planned for SVG v2.0, but AFAIK that was removed from the draft. It's a shame. Here is an article discussing that. (2018, mind you)

Common Themes
大型語言模型 (LLM) 在程式碼生成上的應用:從懷疑到信服 | The use of LLMs in code generation: From skepticism to conviction.

From the readme: This library (including the schema documentation) was largely written with the help of Claude, the AI model by Anthropic. Claude's output was thoroughly reviewed by Cloudflare engineers with careful attention paid to security and compliance with standards. Many improvements were made on the initial output, mostly again by prompting Claude (and reviewing the results). Check out the commit history to see how Claude was prompted and what code it produced.

"NOOOOOOOO!!!! You can't just use an LLM to write an auth library!"
"haha gpus go brrr"
In all seriousness, two months ago (January 2025), I (@kentonv) would have agreed. I was an AI skeptic. I thoughts LLMs were glorified Markov chain generators that didn't actually understand code and couldn't produce anything novel. I started this project on a lark, fully expecting the AI to produce terrible code for me to laugh at. And then, uh... the code actually looked pretty good. Not perfect, but I just told the AI to fix things, and it did. I was shocked.
To emphasize, this is not "vibe coded". Every line was thoroughly reviewed and cross-referenced with relevant RFCs, by security experts with previous experience with those RFCs. I was trying to validate my skepticism. I ended up proving myself wrong.
Again, please check out the commit history -- especially early commits -- to understand how this went.

kentonv | source

I'm the author of this library! Or uhhh... the AI prompter, I guess...

I'm also the lead engineer and initial creator of the Cloudflare Workers platform.
--------------
Plug: This library is used as part of the Workers MCP framework. MCP is a protocol that allows you to make APIs available directly to AI agents, so that you can ask the AI to do stuff and it'll call the APIs. If you want to build a remote MCP server, Workers is a great way to do it! See:
https://blog.cloudflare.com/remote-model-context-protocol-se...
https://developers.cloudflare.com/agents/guides/remote-mcp-s...
--------------
OK, personal commentary.
As mentioned in the readme, I was a huge AI skeptic until this project. This changed my mind.
I had also long been rather afraid of the coming future where I mostly review AI-written code. As the lead engineer on Cloudflare Workers since its inception, I do a LOT of code reviews of regular old human-generated code, and it's a slog. Writing code has always been the fun part of the job for me, and so delegating that to AI did not sound like what I wanted.
But after actually trying it, I find it's quite different from reviewing human code. The biggest difference is the feedback loop is much shorter. I prompt the AI and it produces a result within seconds.
My experience is that this actually makes it feels more like I am authoring the code. It feels similarly fun to writing code by hand, except that the AI is exceptionally good at boilerplate and test-writing, which are exactly the parts I find boring. So... I actually like it.
With that said, there's definitely limits on what it can do. This OAuth library was a pretty perfect use case because it's a well-known standard implemented in a well-known language on a well-known platform, so I could pretty much just give it an API spec and it could do what a generative AI does: generate. On the other hand, I've so far found that AI is not very good at refactoring complex code. And a lot of my work on the Workers Runtime ends up being refactoring: any new feature requires a bunch of upfront refactoring to prepare the right abstractions. So I am still writing a lot of code by hand.
I do have to say though: The LLM understands code. I can't deny it. It is not a "stochastic parrot", it is not just repeating things it has seen elsewhere. It looks at the code, understands what it means, explains it to me mostly correctly, and then applies my directions to change it.

對大型語言模型 (LLM) 廣泛採用的擔憂:技能貶值與資源集中化 | Concerns about widespread LLM adoption: Skill devaluation and resource concentration.

Quite literally this is what I’m trying to get at with my resistance to LLM adoption in the current environment. We’re not using it to do hard work, we’re throwing it everywhere in an intentional decision to dumb down more people and funnel resources and control into fewer hands.

Current AI isn’t democratizing anything, it’s just a shinier marketing ploy to get people to abandon skilled professions and leave the bulk of the populace only suitable for McJobs. The benefits of its use are seen by vanishingly few, while its harms felt by distressingly many.
At present, it is a tool designed to improve existing neoliberal policies and wealth pumps by reducing the demand for skilled labor without properly compensating those affected by its use, nor allowing an exit from their walled gardens (because that is literally what all these XaaS AI firms are - walled gardens of pattern matchers masquerading as intelligence).

大型語言模型 (LLM) 提升生產力,但也增加認知負荷 | LLMs increase productivity but also increase cognitive load.

It took me a few days to build the library with AI.

I estimate it would have taken a few weeks, maybe months to write by hand.
That said, this is a pretty ideal use case: implementing a well-known standard on a well-known platform with a clear API spec.
In my attempts to make changes to the Workers Runtime itself using AI, I've generally not felt like it saved much time. Though, people who don't know the codebase as well as I do have reported it helped them a lot.
I have found AI incredibly useful when I jump into other people's complex codebases, that I'm not familiar with. I now feel like I'm comfortable doing that, since AI can help me find my way around very quickly, whereas previously I generally shied away from jumping in and would instead try to get someone on the team to make whatever change I needed.

kentonv | source

I’ve been using Claude (via Cursor) on a greenfield project for the last couple months and my observation is:

1. I am much more productive/effective
2. It’s way more cognitively demanding than writing code the old-fashioned way
3. Even over this short timespan, the tools have improved significantly, amplifying both of the points above

對大型語言模型 (LLM) 生成程式碼的審查與驗證的擔憂,以及對經驗豐富的工程師的需求 | Concerns about reviewing and validating LLM-generated code and the need for experienced engineers.

The million-dollar question is not whether you can review at the speed the model is coding. It is whether you can trust review alone to catch everything.

If a robot assembles cars at lightning speed... but occasionally misaligns a bolt, and your only safeguard is a visual inspection afterward, some defects will roll off the assembly line. Human coders prevent many bugs by thinking during assembly.

This is my problem I run into quite frequently. I have more trouble trying to explain computing or architectural concepts in natural language to the AI than I do just coding the damn thing in the first place. There are many reasons we don't program in natural language, and this is one of them.
I've never found natural language tools easier to use, in any iteration of them, and so I get no joy out of prompting AI. Outside of the increasingly excellent autocomplete, I find it actually slows me down to try and prompt "correctly."

diggan | source

The thing is you need to know what exactly LLM should create and you need to know what it is doing wrong and tell it to fix it. Meaning, if you don't already have skill to build something yourself, AI might not be as useful. Think of it as keyboard on steroids. Instead of typing literally what you want to see, you just describe it in detail and LLM decompresses that thought.

大型語言模型 (LLM) 開啟了新的軟體開發可能性,特別是在客製化和自動化方面 | LLMs open up new software development possibilities, especially in customization and automation.

I think there's a huge huge space of software to build that isn't being touched today because it's not cost-effective to have an engineer build them.

But if the time it takes an engineer to build any one thing goes down, now there are a lot more things that are cost effective.
Consider niche use cases. Every company tends to have custom processes and workflows. Think about being an accountant at one company vs. another -- while a lot of the job is the same, there will always be parts that are significantly different. Those bespoke processes often involve manual labor because off-the-shelf accounting software cannot add custom features for every company.
But what if it could? What if an engineer working with AI could knock out customer-specific features 10x as fast as they could in the past. Now it actually makes sense to build those features, to improve the productivity of each company's accounting department.
It's hard to say if demand for engineers will go down or up. I'm not pretending to know for sure. But I can see a possibility that we actually have way more developers in coming years!

kentonv | source

> I think there's a huge huge space of software to build that isn't being touched today because it's not cost-effective to have an engineer build them.

That's definitely an interesting area, but I think we'll actually see (maybe) individual employees solving some of these problems on their own without involving IT/the dev team.
We kind of see it already - a lot of these problem spaces are being solved with complex Excel workflows, crappy Access databases, etc. because the team needed their problem solved now, and resources couldn't be given to them.
Maybe AI is the answer to that so that instead of building a house of cards on Excel, these non-tech teams can have something a little more robust.
It's interesting you mentioned accounting, because that's the one department/area I see taking off and running with it the most. They are already the department that's effectively programming already with Excel workflows & DSLs in whatever ERP du jour.

大型語言模型 (LLM) 對軟體工程師角色的潛在影響:生產力提升與就業市場變化 | Potential impact of LLMs on the role of software engineers: Productivity gains and changes in the job market.

This is exactly the direction I expect AI-assisted coding to go in. Not software engineers being kicked out and some business person pressing a few buttons to have a fully functional app (as is playing out in a lot of fantasies on LinkedIn & X), but rather experienced engineers using AI to generate bits of code and then meticulously reviewing and testing them.

大型語言模型 (LLM) 的成本效益:推論成本低廉且持續下降 | Cost-effectiveness of LLMs: Inference is cheap and getting cheaper.

Inference is actually quite cheap. Like, a highly competitive LLM can cost 1/25th of a search query. And it is not due to inference being subsidized by VC money.

It's also getting cheaper all the time. Something like 1000x cheaper in the last two years at the same quality level, and there's not yet any sign of a plateau.

Really a lot of innovation, even at the very cutting edge, is about combining old things in new ways, and these are great productivity tools for this.
I've been "vibe coding" quite a bit recently, and it's been going great. I still end up reading all the code and fixing issues by hand occasionally, but it does remove a lot of the grunt work of looking up simple things and typing out obvious code.
It helps me spend more time designing and thinking about how things should work.
It's easily a 2-3x productivity boost versus the old fashioned way of doing things, possibly more when you take into account that I also end up implementing extra bells and whistles that I would otherwise have been too lazy to add, but that come almost for free with LLMs.
I don't think the stereotype of vibe coding, that is of coding without understanding what's going on, actually works though. I've seen the tools get stuck on issues they don't seem to be able to understand fully too often to believe that.
I'm not worried at all that LLMs are going to take software engineering jobs soon. They're really just making engineers more powerful, maybe like going from low level languages to high level compiled ones. I don't think anyone was worried about the efficiency gains from that destroying jobs either.
There's still a lot of domain knowledge that goes into using LLMs for coding effectively. I have some stories on this too but that'll be for another day...

I am sorry, but the tech world is completely missing the forest for the trees here. LLM's are talked about purely as tools that were created to help devs. Some love them, some hate them, but pretty much all of them seem unaware that LLMs allow non-tech people to automate tasks with a computer without having to go through a 3rd-party-created interface.

To find what is considered an intermediate vs a final artifact from cargo, you need to check out https://doc.rust-lang.org/cargo/reference/build-cache.html
We are working on making this clearer with https://github.com/rust-lang/cargo/issues/14125 where there will be `build.build-dir` (intermediate files) and `build.target-dir` (final artifacts).
When you do a `cargo build` inside of a library, like `clap`, you will get an rlip copied into `build.target-dir` (final artifacts). This is intended for integration with other build systems. There are holes with this workflow though but identifying all of the relevant cases for what might be a "safe" breakage is difficult.

epage | source

This metadata has been around for years, and Rust releases new versions every six weeks. Whether or not it's technically a "breaking change" or not, it's not unreasonable to spend a likely time to figure out if something will break for someone if they remove it; it's only another month and a half at most before the next chance to stabilize it comes.

At a higher level, as much as it's easier to pretend that "breaking" or "non-breaking" changes are a binary, the terms are only useful in how they describe the murkier reality of how people actually use something. The point of having those distinctions is in how they communicate things to users; developers are promising not to break certain things so that users can rely on them to remain working. That doesn't mean that other changes won't have any impact to users though, and there's nothing wrong with developers taking that into account.
As an analogy, imagine if I promise to mow your lawn every week, and then I mow your neighbor's lawn as well without making them the same promise. I notice that my old mower takes a long time to finish your lawn, and I realize that a newer electric mower with a higher power usage would help me do it faster. I need to make sure that higher power usage is safe for me to use on your property, but I'm not breaking my promise to you if I delay my purchase to check with your neighbor about whether it would be safe for theirs as well and take that into account in my decision. That doesn't mean I'm committing to only buying it if it's safe for their lawn, but it's information that still has some value for me to know in advance, and if it means that your lawn will continue to get cut with the old mower while I figure that out, it doesn't mean that I'm somehow elevating the concern of their lawn to the same level as yours. You might not choose to care about the neighbors lawn in my position, but I don't think it's particularly "wild" that some people might think it's worthwhile to take it into consideration.

While I can imagine some edge cases where this approach can be meaningful, isn't that generally counterproductive?

Not only one has to be actively aware about all the behaviors they don't document (which is surely not an easy task for any large project), they have to spend a non-negligible amount of time adding randomness to it in a way that would still allow all the internal use cases to work cohesively. This means you spend less time on doing something actually useful.
Instead of randomizing, it should be sufficient to just figure out the semantics for clearly communicating what's the public APIs and stable, and what's internal and subject to change at whim. And maybe slap a big fat warning "if something is not documented - it's internal, and $deity help you if you depend on it, for we make no guarantees except that it'll break on some fine day and that day won't be so fine anymore". Then it's not your problem.

Surprised the harsh winters weren't mentioned. Winters in New England, New York, and parts of Pennsylvania are more severe than anything most British soldiers would have experienced save for those stationed in Canada or from the Scottish Highlands.

ilamont | source

Mosquitos are very abundant in the North. Canada, Russia, Siberia and Scandinavia all have huge numbers of them, as well as long spring summer days. Many British soldiers died as they had zero tolerance, and many died with the only wounds being mosquito bites and the systemic infections that followed - there was zero medication of any kind against infections. Some may have lost so much blood that they died from that alone. Having been in Northern Ontario's(Canada) temperate jungles, I have experienced these swarms. Of course I had DEET and screened hats/clothes. Black flies are even worse because they are a lot smaller and they crawl into small crevices at ankles/neck and gnaw away a piece of flesh to take away = lay an egg. Their cutters are sharp and have a numbing saliva so you can not feel the bites and you notice the bite when the blood suns down = it does not clot because it has anti-clot chemicals along with the numbing chemicals also in their saliva. Again good clothes/hats work well with velcro snugged all around all ankles/wrists/neck. Nets can not be near the skin, as mosquitos can reach across about 1/4" air gaps and get you. Get a hole in the net = they find it. Now try and work at 90 degrees and 100% humidity = a sweatshop.

Huge guys, massive swarms of them, sitting on people and backpacks in hundreds as they walked. Te only protection was thick clothing over everything. Still, any exposed part of skin had 10-20 bites easily. They were harmless, and once I've got used to that weren't itching, as long as I didn't accidentally scratched/bruised over them.

> Ie oversized mosquitoes (where swamps were not completely drained hundred years ago). The native mosquitoes of the DC area can grow to a body length of about 1 inch or a bit longer (~3cm).

They have largely been out competed by the invasive "black fly" version (https://en.wikipedia.org/wiki/Aedes_albopictus) that is active all day (and so, is much more a nuisance, even if they are only about 3/8 inch (~1cm) body length).

Abstract:

We introduce Reasoning Gym (RG), a library of reasoning environments for reinforcement learning with verifiable rewards. It provides over 100 data generators and verifiers spanning multiple domains including algebra, arithmetic, computation, cognition, geometry, graph theory, logic, and various common games. Its key innovation is the ability to generate virtually infinite training data with adjustable complexity, unlike most previous reasoning datasets, which are typically fixed. This procedural generation approach allows for continuous evaluation across varying difficulty levels. Our experimental results demonstrate the efficacy of RG in both evaluating and reinforcement learning of reasoning models.

Random thought. Do antibiotics kill any sort of permanent seemingly benign outside bacteria in the body?

I guess I'm asking did we used to have persistent, ongoing infections that now get wiped out every so often as a side effect of taking antibiotics?

Not just antibiotics to consider along this line of thought. We historically had a higher load of parasites. Far more of the population had some amount of parasites more of the time. Things like sewer systems/sanitation/clean drinking water/bathing and personal hygiene/wearing shoes/not having piles of animal feces all over the streets. That all changed the amount of exposure to parasites for the common person. We know it affected our immune systems (overall rates of allergies increased). We do not know how it affected our brains. Makes intuitive sense that it must apply to bacteria as well. Before foods were pasteurized (and before refrigeration), for example, we were exposed to more dietary sources for bacteria, both beneficial and non-beneficial.

避免審查言論是最佳策略 | Policing speech is a problem best avoided.

Something we have had to deal with in managing educational software with a writing aspect is trying to manage what is offensive to who, in what context and where is not universal at all.

One of the most prime examples, at one point a number of terms related to homosexuality had made it onto the list at the request of a larger district. These are also terms that are being reclaimed, and it was... a difficult problem to try to satisfy everyone, and it did upset other districts. I believe their patterns were all but removed eventually.
We have a fought over the list of definitions and every change provoked controversy. Our current solution is just that we mark items for teacher review but don't tell them why. We don't say they are offensive, we don't say what the problematic words are. We just say it might need review. That's worked pretty well so far.
All this is to say, policing speech is a problem best avoided.

過濾不雅詞彙的系統常造成困擾,因為它們可能會錯誤地審查無害的詞語,尤其是在多語言環境下。 | Cuss filters often cause frustration by censoring harmless words, especially in multilingual contexts.

Typical cuss filter UX:

types something in live chat
some random word from the sentence gets censored out
"Why did this just got censored out?"
check urban disctionary
"Why?????"
Bonus points if its regular ethnonyms that are classified as profanities, so people from that place are having big trouble to tell where they are from.

The Dutch word 'kunt' (je kunt = you can) gets censored in WoW because of 'cunt'. That is, if you have mature language filter on. I have this on because I have no interest in raging kids in said game, but I do want to read simple, common Dutch words. Annoys me to this day. CS gave the obvious answer (WONTFIX, with obvious workaround disabling the mature language filter altogether). It could be solved easily by looking at context instead of simple blacklisting. I connect from a Dutch IPv4. I sometimes talk Dutch. The same would be true for the other endpoint.

It's not just you, and I would say that there seems to have been a general coarsening of society. The other day I saw someone with a bumper sticker saying "I pooped today", which I did find funny, but I reflected that it never would've been socially acceptable 30 years ago or so. People seem to have rejected the idea that some things are not acceptable to discuss or display openly. See for example "let your freak flag fly" and so on.

There are pros and cons to it, I suppose. I don't think it's bad for gay people to be out of the closet, for example. But I also find stuff like the rampant swearing* or "I pooped today" to be a bit troubling as I get older and think "man I wouldn't want my kids to learn it's ok to talk like that".
* not casting stones, I have a very strong swearing habit myself that I try to curb. It's hard.

My favorite is Havelock the Dane: A Tale of Old Grimsby, first written circa the 14th century but thought to be much older. When you listen to it, it is apparent that the author and the intended audience know 100x more about nautical things than you do. It's also charmingly simplistic; the main character is sort of like Conan the Barbarian. He'll do things like "lift a stone the weight of an ox and throw it the length of two men."

I don't love how some people think I'm some sort of implicit threat or ticking time bomb because of stories they've heard or read about people like me. Like most people in the office, I just want to be able to do my work. I'm not trying to cause problems for people. The thought that me living my life makes some people feel like they have to walk on eggshells is awful. Luckily most people don't see me as some kind of threat like this, but it's obvious when people do.
I can't speak for everyone, but for me personally, going to HR for _anything_ is terrifying. Going to HR to complain about a valid grievance is scary. Going to HR over a simple mistake that a well-meaning person made feels like it would explode my career. It's hard enough to get a job as an openly transgender person.

鄉村地區的 LGBTQ (同性戀、雙性戀、跨性別) 居民在法律上結婚的可能性,實際上比城市居民更高,儘管這可能受到尋找伴侶的困難等因素影響。 | LGBTQ rural residents are actually more likely to be legally married than their urban counterparts, although this may be influenced by factors such as the difficulty of finding partners.

> But my analysis of a 2013 Pew Survey of LGBTQ Americans -- the latest available comprehensive national survey data on this population -- showed that LGBTQ rural residents are actually more likely to be legally married than their urban counterparts -- 24.8% compared with 18.6%. This aligns with what I’ve heard in interviews. The rural LGBTQ people I spoke with placed a high value on monogamy – on what many of them consider a “normal” life.

This is one of those cases where causality is implied but is questionable. Finding lovers in the sticks is hard enough; it is exceptionally difficult if you are queer, and that's going to influence behavior and choices in all sorts of ways, and those can be rationalized in all sorts of ways, too.
A less charged example: adults living in cities are (probably) more likely to participate in, and value participating in, team sports. Let's assume they report honestly as such on a questionnaire.
Obviously, there are more opportunities to play sports in cities, but does that imply that rural folks wouldn't partake at about the same rate if they could, even though they say that they wouldn't?
I can see plausible arguments in either direction, and for several kinds of selection and reporting biases.

對物聯網 (IoT) 裝置安全性的擔憂,特別是關於信任根 (roots of trust) 的實施,以及這如何限制使用者對其裝置的控制權。 | Concerns about IoT device security, particularly regarding the implementation of "roots of trust" and how it restricts user control over their devices.

Please read the article before commenting, because I find the proposed solution a bit worrisome.

Of course we should secure IoT, but the article is about one very particular kind of security: roots of trust. The idea is that devices shouldn't run unsigned software, so forget about custom firmwares, and generally owning the hardware.
There is a workaround, sometimes called "user override", where the owners can set their own root-of-trust so that they can install custom software. It may involves some physical action, like pushing a switch, so that it cannot be done remotely by a hacker. But the article doesn't mention that, in fact, it especially mentions that the manufacturer (not the user) is to be trusted and an appropriate response is to reset the device, making it completely unusable for the user. Note that such behavior is considered unacceptable by GPLv3.
There are some cases where it is appropriate, GPLv3 makes a distinction between hardware sold to businesses and "User Products", and I think that's fair. You probably don't want people to tinker with things like credit card terminals. But the article makes no such distinction, even implying that consumer goods are to be included.

GuB-42 | source

Not only that, "roots of trust" and locking users out of their devices is the thing that causes the IoS omnishambles. The foundational problem is that some company makes millions of devices and then goes out of business or otherwise stops supporting them, but because the users are locked out of the device, nobody else can do it either. Meanwhile people continue to use them because the device is still functional modulo the unpatched security vulnerabilities.

If anyone could straightforwardly install the latest DD-WRT or similar then it's solved, because then you don't have to replace the hardware to replace the software, and the manufacturer could even push a community firmware to the thing as their last act before discontinuing support.

> and the manufacturer could even push a community firmware to the thing as their last act before discontinuing support.

This should be held in escrow before the device can be sold. And the entity doing the escrow service should periodically build the software and install it onto newly-purchased test devices to make sure it's still valid.
If the company drops support, either by going out of business or by simply allowing issues to go unaddressed for too long, then the escrowed BSP/firmware is released and the people now own their own hardware.

The only long term viable approach for IoT security is to not allow these devices on the Internet in the first place. Have the WiFi Access Point, or some other gateway, act as the broker for all information, and the default is each device sees nothing until given permission. *
Whenever this comes up people raise the point that this won't work because it disincentivizes making devices to slurp data, but it's not like that ecosystem actually exists at all, with the exception of smart TV which hardly counts as IoT. Consumer IoT hasn't taken off because consumers are rightly paranoid about bait-and-switch and being left with useless devices in the walls of their homes.

A piece of junk that goes out today that maybe still flies under the radar and nobody bothers to hack it isn't going to fly under the radar in a world where there's 10, 20, 50 times more "software engineering" power in the world, in the hands of a lot more people.

One note on API design: I think it's a FANTASTIC idea to have default `rand()` functions available, since very often, you don't really care about the generator and you're just like "just give me a random number, i don't care how". But if you do, you shouldn't have a `seed()` function, because that means you can then never upgrade it without breaking your API contract. It should always be seeded with entropy. This is why glibc's `rand()` is still using an LCG from the late neolithic, they can't ever update it without breaking a gazillion applications and tests. This is the classic example of "Hyrum's law". Doing this also helps with thread-safety: you can just make the seed/state thread-local and then it just works.
Basically, if you want the ability to seed your PRNG, you also need to specify the generator explicitly. The global one is for convenience only, and there should be no ability in the API to seed it.
EDIT: btw, this is a really nice thing about C++, doing this is dead easy:
    int rand() {         thread_local generator my_generator { seed_with_entropy() };         return my_generator.rand();     }

Thanks for sharing, this is a very well-written and useful set of libraries, not just random, but also the other sub-libraries of utl.

One caveat:
> Note 2: If no hardware randomness is available, std::random_device falls back onto an internal PRNG ....
> ...
> std::random_device has a critical deficiency in it's design — in case its implementation doesn't provide a proper source of entropy, it is free to fallback onto a regular PRNGs that don't change from run to run. The method std::random_device::entropy() which should be able to detect that information is notoriously unreliable and returns different things on every platform.
> entropy() samples several sources of entropy (including the std::random_device itself) and is (almost) guaranteed to change from run to run even if it can't provide a proper hardware-sourced entropy that would be suitable for cryptography.
Personally, I think it would be best if there was a way to communicate to the system (or here, to the library in specific) what is the use case. For cryptographic applications, I don't want the library to fall back gracefully to something insecure; I would want a dark red critical error message and immediate termination with an "insufficient entropy error" error code.
However, for a game graceful degradation might be quite okay, because nobody is going to die in the real world if a monster behaves a little less random.
I learned a lot about recent advances in pseudo-random number generators by reading your code and associated documentation, including some stuff that DEK has yet to incorporate into volume 2 of TAOCP. ;)

- Faster uniform / normal distributions that produce same sequences on every platform
This is very useful if you want to reliably repeat simulations across platforms!
One question:
    template<class T>     constexpr T& rand_choice(std::initializer_list<T> objects) noexcept;
Isn't this returning a reference to a local variable? In my understanding, 'objects' is destroyed when rand_choice() returns.

Nice trick:

> How is it faster than std: It uses the fact that popcount of a uniformly distributed integer follows a binomial distribution. By rescaling that binomial distribution and adding some linear fill we can achieve a curve very similar to a proper normal distribution in just a few instructions. While that level of precision is not suitable for a general use, in instances where quality is not particularly important (gamedev, fuzzing) this is perhaps the fastest possible way of generating normally distributed floats.

If you don't need "predictable randomness", like for repeatable statistical simulations, then absolutely, you should only use getrandom(). On recent Linux, this is implemented in the vDSO and is super fast. Few excuses now to use anything different.

zx2c4 | source

The portable API is getentropy, which glibc provides as a simple wrapper around getrandom. getentropy was added to POSIX, and is also available on most modern unix systems, including FreeBSD, Illumos, NetBSD, macOS, OpenBSD, and Solaris.

arc4random has been provided by glibc 2.36 (2022), and is available on all the above-mentioned systems as well. If you don't want to make a syscall per request (outside Linux), just use arc4random; it'll be the fastest method available. musl libc lacks arc4random, unfortunately, but you can always ship a small wrapper.
Systems that support arc4random also support arc4random_uniform, which is a way to get an unbiased unsigned integer between 0 and N (up to 2^32-1). That's probably the most important reason to use the arc4random family.

製作氮化三碘的有趣經驗,通常在高中化學實驗室進行 | Experiences of making nitrogen triiodide as a fun activity, often done in high school chemistry labs.

A fun thing to make. I made this in the high school chemistry room after school. Filter paper with some iodine crystals, pour some ammonia over and wait for it to dry (as I recall). I am not sure where I learned about it. Often my dad, who was a chemist then, would tell me little tricks like this. (He also turn me on to slathering a small amount of potassium permanganate with glycerin.)

Anyway, I was walking with it after I made it (when it was still damp and in the filter paper) and I accidentally dropped the filter paper in the school hallway. I picked up what I could (I suppose I should have gone back and mopped it up).
It was fun, the small explosions, like tap shoes clacking, when it was dry and walked upon. (Too bad it left brown stains on the linoleum.)
I was fortunate to have not had a large quantity dry. It can be pretty dangerous in large amounts I am told.

心算估計對數 (logarithm) 的技巧 | Techniques for estimating logarithms in your head.

Here's all you really need to know about logs when estimating in your head:

The number of digits minus one is the magnitude (integer). Then add the leading digit like so:
1x = ^0.0
2x = ^0.3 (actually ^0.301...)
pi = ^0.5 (actually ^0.497...)
5x = ^0.7 (actually ^0.699...)
Between these, you can interpolate linearly and it's fine for estimating. Also 3x is close enough to pi to also be considered ^0.5.
In fact, if all you're doing is estimating, you don't even really need to know the above log table. Just use the first digit of the original number as the first digit past the decimal. So like 6000 would be ^3.6 (whereas it's actually ^3.78). It's "wrong" but not that far off if you're using logarithmetic for napkin math.

saulpw | source

I don't know about powers-of-10; but, you can use something similar to bootstrap logs-in-your-head.

So, 2^10=1024. That means log10(2)~3/10=0.3. By log laws: 1 - .3 = 0.7 ~ log10(5).
Similarly, log10(3)*9 ~ 4 + log10(2); so, log10(3) ~ .477.
Other prime numbers use similar "easy power rules".
Now, what's log10(80)? It's .3*3 + 1 ~ 1.9. (The real value is 1.903...).
The log10(75) ~ .7*2+.477 = 1.877 (the real answer is 1.875...).
Just knowing some basic "small prime" logs lets you rapidly calculate logs in your head.

For log(3) I prefer the "musical" approximation 2^19 ~ 3^12. This is a "musical" fact because it translates into 2^(7/12) ~ 3/2 - that is, seven semitones make a perfect fifth). Together with log(2) ~ 3/10 that gives log(3) ~ 19/40.

Also easy to remember: 7^4 = 2401 ~ 2400. log(2400) = log(3) + 3 log(2) + 2 ~ 19/40 + 3 * 12/40 + 2 = 135/40, so you get log(7) ~ 135/160 = 27/32 = 0.84375.

If you take into account the time and technical possibilities it's not even close. And the original movies have more memorable things overall. I mean the two villains alone are all time greats. The music is also better (imo).

But most importantly, I think Andor is less strong without the original movies. The looming threat and the Mothma high-society scenes become a lot less powerful.

If I didn’t know a friend who just built a new fence and had one but had an option of renting one from a guy down the street for $10, that’s what I’d do. And I’d be so happy I didn’t just spent $50 and then have to either store a tool that’s never used again or try to sell it.
I think DIY is growing, it’s a great way to save money and it’s only becoming easier with YouTube to help you through most any job. Good luck with the site!

錯誤處理方法與訊息堆疊 (Error handling approaches and message stacking) | Error handling approaches and message stacking

The implementation of WithMeta() is flawed. Not only is it not concurrency-safe, every nested call will be modifying the parent map.

The way to do this in a safe and performant manner is to structure the metadata as a tree, with a parent pointing to the previous metadata. You'd probably want to do some pooling and other optimizations to avoid allocating a map every time. Then all the maps can be immutable and therefore not require any locks. To construct the final map at error time, you simply traverse the map depth-first, building a merged map.
I'm not sure I agree with the approach, however. This system will incur a performance and memory penalty every time you descend into a new metadata context, even when no errors are occurring. Building up this contextual data (which presumably already exists on the call stack in the form of local variables) will be constantly going on and causing trouble in hot paths.
A better approach is to return a structured error describing the failed action that includes data known to the returner, which should have enough data to be meaningful. Then, every time you pass an error up the stack, you augment it with additional data so that everything can be gleaned from it. Rather than:
    val, err := GetStuff()
    if err != nil {
      return err
    }
You do:
    val, err := GetStuff()
    if err != nil {
      return fmt.Errorf("getting stuff: %w")
    }
Or maybe:
    val, err := GetStuff()
    if err != nil {
      return wrapWithMetadata(err, meta.KV("database", db.Name))
    }
Here, wrapWithMetadata() can construct an efficient error value that implements Unwrap().
This pays the performance cost only at error time, and the contextual information travels up the stack with a tree of error causes that can be gotten with `errors.Unwrap()`. The point is that Go errors already are a tree of causes.
Sometimes tracking contextual information in a context is useful, of course. But I think the benefit of my approach is that a function returning an error only needs to provide what it knows about the failing error. Any "ambient" contextual information can be added by the caller at no extra cost when following the happy path.

atombender | source

I think this is the way to bubble up error messages that I like the most. Simple, not needing any additional tools, and very practical (sometimes even better than a stack trace).

The idea is to only add information that the caller isn't already aware of. Error messages shouldn't include the function name or any of its arguments, because the caller will include those in its own wrapping of that error.
This is done with fmt.Errorf():
    userId := "A0101"
    err := database.Store(userId);
    if err != nil {
        return fmt.Errorf("database.Store({userId: %q}): %w", userId, err)
    }
If this is done consistently across all layers, and finally logged in the outermost layer, the end result will be nice error messages with all the context needed to understand the exact call chain that failed:
    fmt.Printf("ERROR %v\n", err)
Output:
    ERROR app.run(): room.start({name: "participant5"}): UseStorage({type: "sqlite"}): Store({userId: "A0101"}): the transaction was interrupted
This message shows at a quick glance which participant, which database selection, and which integer value where used when the call failed. Much more useful than Stack Traces, which don't show argument values.
Of course, longer error messages could be written, but it seems optimal to just convey a minimal expression of what function call and argument was being called when the error happened.
Adding to this, the Go code linter forbids writing error messages that start with Upper Case, precisely because it assumes that all this will be done and error messages are just parts of a longer sentence:

結構化錯誤與錯誤代碼的比較 (Structured errors vs. error codes) | Structured errors vs. error codes

These are good general tips applicable to other languages too. I strongly dislike when code returns errors as arbitrary strings rather than classes, as it makes errors extremely difficult to handle; one would presumably want to handle a http 502 diffrernetly to a 404, but if a programmer returns that in a string, I have to do some wonky regex instead of checking the type of error class (or pulling a property from an error class). I've commonly found JS and Go code particularly annoying as they tend to use strings, as the author mentioned.

An additional thing that is useful here would be a stack trace. So even when you catch, wrap & rethrow the error, you'll be able to see exactly where the error came from. The alternative is searching in the code for the string.
For the hate they seem to get, checked exceptions with error classes do give you a lot of stuff for free.

RadiozRadioz | source

No, I want dedicated classes. Be they thrown or returned as a value. Error codes are limiting and serve a different purpose.

Error codes contain only the type of error that occurred and cannot contain any more data. With an error class you can provide context - a 400 happened when making a request, which URL was hit? What did the server say? Which fields in our request were incorrect? From a code perspective, if an error happens I want to know as much detail as possible about it, and that simply cannot be summarised by an error code.
If I want to know the type of an error and do different things based on its type, I can think of no better tool to use than my language's type system handling error classes. I could invent ways to switch on error codes (I hope I'm using a language like Rust that would assert that my handling of the enum of errors is exhaustive), but that doesn't seem very well-founded. For example, using error enums, how do I describe that an HTTP_404 is a type of REQUEST_ERROR, but not a type of NETWORK_CONN_ERROR? It's important to know if the problem is with us or the network. I could write some one-off code to do it, or I could use error classes and have my language's typing system handle the polymorphism for me.
Not that error codes are not useful. You can include an error code within an error class. Error codes are useful for presenting to users so they can reference an operator manual or provide it to customer support. Present the user with a small code that describes the exact scenario instead of an incomprehensible stack trace, and they have a better support experience.
Side note: please don't use strings for things that have discrete values that you switch on. Use enums.

錯誤處理的重要性與時機 (Importance and timing of error handling) | Importance and timing of error handling

One thing that seemingly is missing is the ability to tag a specific error with an error code. You typically want to know that all of a sudden the ”failed to get user” error is being returned a lot. Since the message is a dynamic string you can’t just group by the string so unless you build it as part of your abstraction it becomes very hard to do.

Edit: looking more carefully at the lib I assume that ”tag” is the concept that is supposed to cover this?

vikeri | source

IMO error handling is the sort of thing you really want to get right early on, even in toy projects. It’s very hard to retrofit, and the actual payoff is low until you need it - at which point you definitely don’t want to do the work.

As antithetical as it might be, I tend to just stuff sentry in (no affiliation just a happy user) when I’m setting up the scaffolding, and insert rich context at the edges (in the router, at a DB/serialization/messagebus layer) and the rest usually just works itself out.

Common Themes
利用休息和切換任務來提高生產力,讓潛意識在背景中解決問題。 | Using breaks and task switching to enhance productivity, allowing the subconscious to work on problems in the background.

My thinking is threaded. I maintain lists (in a simple txt file and more recently, in Notes on the Mac) and add the tasks to it. Subtasks go into an indent. I have different notes for regular work/pet project/blog/learning/travel. priority-must-do-now/daily chores is separate one. Every morning I open my priority/daily chores stuff and try and wind that up. And then I just scuttle around the other lists and do whatever my brain tells me I can. I find that some days I do more from the blog notes and some days more from the regular work notes. The notes serve as goals for my brain and it invents/discoveres solutions in no particular order. This makes me more productive because I can switch when I'm bored (which to me is an indication that my brain needs more time to find solutions in this space). And if nothing is hitting the right note, I'll take a nap or read or watch a show for a bit or go for a long walk or hike - anything that's not in the to-do just to give myself the creative space. I find that giving myself problems to solve, and allowing my subconcious brain to invent solutions for it while I do other things actually works quite well for me and allows me to make steady progress.

After taking a break I often realize I can delete all the code from the last hour and either define away the problem entirely, or fix it in a much simpler way.

But it’s so scary to depend on that flash of insight, after all it’s not guaranteed to happen. So you keep grinding in an unenlightened state.

But yeah it is hard to know when you are in too deep sometimes. I find that imposter syndrome usually kicks in with thoughts of "why am I finding this so complex or hard? I bet colleague would have solved this with a simple fix or a concise one-liner! There must be a better way?". TBH this is where I find LLMs most useful right now, to think about different approaches or point-out all the places where code will need to change if I make a change and if there is a less-destructive/more-concise way of doing things that I hadn't thought of.

It's something I've actively used for almost two decades now when dealing with challenges i'm stuck on. I remember one of my professors explaining it as having a 'prepared mind'.
What I do is, before I go to bed, try to summarize the problem to myself as concise as possible (like rubber ducking) and then go to sleep. Very often the next morning I wake up with a new insight or new approach that solves the problem in 10 minutes that took me hours the day before.

I'd love if more ideas I saw in RSC made it to other technologies.

To be clear, I wouldn't suggest someone to implement this manually in their app. I'm just describing at the high level how the RSC wire protocol works, but narratively I wrapped it in a "from the first principles" invention because it's more fun to read.

探討 Progressive JSON 如何優化資料載入,特別是在資料的不同部分準備就緒的時間不同的情況下。 | Exploring how Progressive JSON optimizes data loading, especially when different parts of the data become available at different times.

The article doesn't advocate sending it progressively to make it smaller on the wire. The motivating example is one where some of the data (e.g. posts) is available before the rest of the data in the response (e.g. comments). Rather than:

- Sending a request for posts, then a request for comments, resulting in multiple round trips (a.k.a. a "waterfall"), or,
- Sending a request for posts and comments, but having to wait until the commends have loaded to get the posts,
...you can instead get posts and comments available as soon as they're ready, by progressively loading information. The message, though, is that this is something a full-stack web framework should handle for you, hence the revelation at the end of the article about it being a lesson in the motivation behind React's Server Components.

aloha2436 | source

Part of the point I'm making is that an out-of-order format is more efficient because we can send stuff as it's ready (so footer can go as soon as it's ready). It'll still "slot in" the right place in the UI. What this lets us do, compared to traditional top-down streaming, is to progressively reveal inner parts of the UI as more stuff loads.

討論 Progressive JSON 在解決延遲問題上的優勢,即使資料量不大。 | Discussing the advantages of Progressive JSON in addressing latency issues, even when the data size is not large.

Progressive JPEG make sense, because it's a media file and by nature is large. Text/HTML on the other hand, not so much. Seems like a self-inflicted solution where JS bundles are giant and now we're creating more complexity by streaming it.

turtlebits | source

Things can be slow not because they're large but because they take latency to produce or to receive. The latency can be on the server side (some things genuinely take long to query, and might be not possible or easy to cache). Some latency may just be due to the user having poor network conditions. In both cases, there's benefits to progressively revealing content as it becomes available (with intentional loading stages) instead of always waiting for the entire thing.

I have seen Dan's "2 computers" talk and read some of his recent posts trying to explore RSC and their benefits.

Dan is one of the best explainers in React ecosystem but IMO if one has to work this hard to sell/explain a tech there's 2 possibilities 1/ there is no real need of tech 2/ it's a flawed abstraction
#2 seems somewhat true because most frontend devs I know still don't "get" RSC.
Vercel has been aggressively pushing this on users and most of the adoption of RSC is due to Nextjs emerging as the default React framework. Even among Nextjs users most devs don't really seem to understand the boundaries of server components and are cargo culting
That coupled with fact that React wouldn't even merge the PR that mentions Vite as a way to create React apps makes me wonder if the whole push for RSC is for really meant for users/devs or just as a way for vendors to push their hosting platforms. If you could just ship an SPA from S3 fronted with a CDN clearly that's not great for Vercels and Netflifys of the world.

對 Progressive JSON 的實用性表示懷疑,認為它是一種「尋找問題的解決方案」,並建議使用替代方法,例如優化 API 層和多個請求。 | Expressing skepticism about the practicality of Progressive JSON, considering it a "solution looking for a problem," and suggesting alternative approaches like optimizing the API layer and multiple requests.

I'll try to explain why this is a solution looking for a problem.

Yes, breadth-first is always an option, but JSON is a heterogenous structured data source, so assuming that breadth-first will help the app start rendering faster is often a poor assumption. The app will need a subset of the JSON, but it's not simply the depth-first or breadth-first first chunk of the data set.
So for this reason what we do is include URLs in JSON or other API continuation identifiers, to let the caller choose where in the data tree/graph they want to dig in further, and then the "progressiveness" comes from simply spreading your fetch operation over multiple requests.
Also often times JSON is deserialized to objects so depth-frst or breadth-first doesn't matter, as the object needs to be "whole" before you can use it. Hence again: multiple requests, smaller objects.
In general when you fetch JSON from a server, you don't want it to be so big that you need to EVEN CONSIDER progressive loading. HTML needs progressive loading because a web page can be, historically especially, rather monolithic and large.
But that's because a page is (...was) static. Thus you load it as a big lump and you can even cache it as such, and reuse it. It can't intelligently adapt to the user and their needs. But JSON, and by extension the JavaScript loading it, can adapt. So use THAT, and do not over-fetch data. Read only what you need. Also, JSON is often not cacheable as the data source state is always in flux. One more reason not to load a whole lot in big lumps.
Now, I have a similar encoding with references, which results in a breadth-first encoding. Almost by accident. I do it for another reason and that is structural sharing, as my data is shaped like a DAG not like a tree, so I need references to encode that.
But even though I have breadth-first encoding, I never needed to progressively decode the DAG as this problem should be solved in the API layer, where you can request exactly what you need (or close to it) when you need it.

原作者 (original developer) 已於 2021 年底過世,目前專案由他人接手,但進展緩慢,需要更多貢獻者 (contributors),尤其是有 Javascript 技能的人。 | The original developer passed away in late 2021, and the project is now being maintained by someone else, but progress is slow and more contributors are needed, especially those with Javascript skills.

Sadly late 2021 the original dev passed away. Someone has taken over stewardship of the project but it is currently moving slowly and they are seeking more contributors (javascript skills are a plus).

He was a bit of a hn user and seemed good natured and pleasant. Though I didn't know him I was sad to hear he'd passed both as a Redirector user and a fan of good people doing good things. I know he'd mentioned being happy to get recognition on here. https://news.ycombinator.com/user?id=einaregilsson

For instance, I use to: redirect new reddit site to old.reddit.com

I keep a blog on wordpress.com, but I really dislike their new blog admin interface, but the interface one can still be accessed , so I redirect to there to edit my posts on the old interface
I use some alternative front-ends, like imginn.com, which is alternative front-end to instagram, so I set to redirect links there.
This sort of thing.

84. Figma Slides Is a Beautiful Disaster

簡報被用作文件而非輔助工具,導致資訊過載的幻燈片。 | Slides are often used as documents instead of aids, leading to information-heavy slides.

In my experience, people also use slides as a document rather than an aide. In all my presentations I prefer to use slides as a companion to my planned speech. Then afterwards I'm completely surprised when people ask for my slides. I send them gladly but they're completely useless on their own.

So I have also experienced my managed pushing me to put all the information on the slide so that you can just read the slides and understand all the ideas, and the presenter is reduced to a voice over.

seventhtiger | source

I call it two kinds of slides: presentation slides and reading slides. The latter type probably should be a different type of document, but they are wildly popular.

And since you're often expected to hand over the slides afterwards, I try to find a middle ground. The slide will have more than 5 words, but hopefully not too many. Pictures/graphs help with this.

蘋果風格的簡報(簡潔、視覺化)與企業範本之間的衝突,以及簡報形式與功能的權衡。 | The conflict between Apple-style presentations (clean, visual) and corporate templates, and the trade-off between presentation form and function.

When I make Apple style presentations (no visual noise, no bullet point lists, one appealing visual / idea on one slide etc and narrating the story instead of showing densely packed info in one slide after another), I can literally see how my audience is really enjoying the presentation, getting the idea, but then constantly management approaches me telling me to use the corporate template, stick to the template, use the template elements, etc.

They just don’t get it. What comprises a good presentation. Even if they themselves enjoy the content while they are in the audience.
Futile.
Edit: Tangential: I am the only one using a MacBook in a company of 700+ coworkers.

submeta | source

I've struck a tentative balance with the main one line messages being the slide titles, with other slide content buttressing the main point.

I can tell the audience to ignore the content and focus on the title for certain slides; or just repeat the slide title before and after for emphasis, etc... while also having access to all kinds of supporting evidence (as is often necessary for technical talks).
PS: Beware that stripped-down / minimalist presentations are suitable for the specific kind of communication / impressionism that Apple marketing is known for. But that's almost exactly the opposite of what is necessary in other situations. So that style is far from universally applicable; mustn't elevate form over function.

偏好本地執行的簡報軟體,並避免過度依賴雲端服務,以確保檔案存取和簡報的可靠性。 | Preference for locally running presentation software and avoiding over-reliance on cloud services to ensure file access and presentation reliability.

The lesson I take from this is to just use software that is running locally on the machine, especially when doing presentations. Maybe even have a backup that is a simple PDF that you can show page by page - no animations though but can still show stages of the animation.

daemin | source

Figma has so many things on the go (Sites, Make, etc), I doubt Slides is going to get the investment and TLC it needs.

I also try to avoid cloud first. If servers are slow or down or you're locked out for whatever reason, you won't have access to your own files.
Prefer apps like Powerpoint or Keynote. Local first and back up to the cloud.

史蒂夫·賈伯斯(Steve Jobs)的簡報風格不適合所有人,且過度模仿可能適得其反。 | Steve Jobs' presentation style is not universally applicable, and trying to emulate it too closely can be counterproductive.

Maybe controversial opinion, I'm not sure most people can learn much useful from Steve Jobs, and trying to emulate his presentations.

He had a huge support team to help him polish, and was very skilled. It feels like someone who has never driven a car trying to learn by watching Formula 1. Yes their drivers are amazing at drivers, but you can't really complain when your delivery drivers can't hit F1 speeds.

簡報軟體的改進空間有限,因為重點在於銷售和行銷,而不是美觀的軟體。 | There is limited incentive to improve presentation software because the focus is on sales and marketing, not beautiful software.

Having worked on presentation software, it's more complicated than what it looks like in its surface.

First, considering the base/generic case, you can't really beat Powerpoint, Keynote and Google Slides, they are somewhat free/included in basic accounts, they will get the job done, people are used to Powerpoint, and it's not the core product of any of these companies, there's very little incentive for them to improve that.
Second, because you can't compete on base case, a company needs to target those who will willingly pay for presentation software, that's sales and marketing, they don't care about beautiful software, they care about conversion and data.

教堂鐘聲與時間:許多人分享了他們居住地教堂鐘聲的經驗,包括鐘聲如何幫助他們知道時間,以及鐘聲對他們生活的影響。 | Church bells and timekeeping: Many people shared their experiences with church bells in their localities, including how the bells help them tell time and the impact of the bells on their lives.

I live in a small Swiss village. We have two churches, they ring their bells every hour (number of dong-sounds is equal to the hour). But, they're slightly out of phase, so you can hear two separate churches' bells.

And one of the churches also rings their bells every 15 minutes (1-ring for each quarter). On top of this at 6:00am it rings a whole rhapsody of sounds for whole 5 minutes - "wake up people, time to go to work on a field!".
Initially it may be annoying, eventually you just get used to it, in the end you actually learn to figure out the time from the bell sound and make use of it.

pre-Renaissance the mechanical clock was a show of power for Christian civilization.. one of the many benefits, along with literacy and the written word in all its uses, of the Christian society versus others.. and versus others it was.. on the edges of the Christian world were raiding tribes, marching armies and slaving of all kinds, from the great Central Asia all the way into modern France, from the East, Vikings from the North and African continental peoples from the South.

生物電場與身體特性:有人提出,身體可能具有獨特的生物電場,該電場可以影響細胞生長和特化,並保留個體的獨特性。 | Bioelectric fields and body uniqueness: Someone suggested that the body may have a unique bioelectric field that can influence cell growth and specialization, and retain an individual's uniqueness.

You can take a flatworm, cut it in half, subject it to an electric field so it grows two heads.

Later, without the external field, you can cut it in half and both halfs will grow a second head.
It's not genetic expression, but the electric field of the flatworm that has changed permanently and is directing cell growth.
So if your entire body has its own field, that retains its uniqueness, and can even cause cell specialization what then?
https://www.newscientist.com/article/2132148-bioelectric-twe...
“A totally normal-looking worm with a normal gene expression and stem cell distribution can in fact be harbouring a [body plan] that’s quite different,” says Levin. “That information is stored in a bioelectric pattern – it’s not in the distribution of tissues or stem cells, it’s electrical.”

使用 Tor 瀏覽器 (Tor Browser) 對於匿名性至關重要,因為它具有防指紋 (anti-fingerprinting) 功能,而其他瀏覽器則沒有。使用其他方式可能會洩漏資訊,難以融入 Tor 的使用者群體中。 | Using Tor Browser is crucial for anonymity due to its anti-fingerprinting strategies, which other browsers lack. Using alternative methods may leak information and make it difficult to blend in with the Tor user base.

When you have torsocks or torify for everything, you're gonna leave your footprint through tor, whereas something like Tor Browser is designed specifically not to leave any print on the web.

Using tor directly on the kernel level means that your DNS is gonna leak. Your OS telemetry is gonna leak etc.
It's still a good idea but it should be implemented top to bottom and nothing left in between, otherwise you're de-anonymized quickly.

The main strategy is that most people on Tor are using Tor Browser. This creates a cluster big enough to blend in. If you're using anything else, you're sticking out.

Tor is anonymizing you primarily from the network. There are many use cases where you do want to be authenticated/known to whoever you are talking to. You just want observers to not know.

In your example of correlation of connection times, it may not be your goal to remain anonymous from the network and its participants, you may be interested in the location-hiding properties, and/or adversarial networks (like local government or corporate networks) and firewalls.

I think the tor folks made a fundamental strategic error by pushing that line. Yes, people who face a serious threat need to use tor browser and still pay attention to other ways to leak etc. But if we'd got 'tor everywhere' it would still make mass surveillance a lot harder. For one thing, today mass surveillance can detect who is using tor. If everyone was using it that wouldn't matter.
