A WASM DB saved our data analysis engine
by vinserello | 2025-10-01 07:47:29+00:00
Our demo totally crashed on a spreadsheet. We knew the old engine wasn't it, so we just yeeted it and rebuilt with DuckDB and WebAssembly. Basically, we put a whole analytical database inside your browser with WASM. Now parsing and queries run parallel, no cap.

It's actually wild now: 500MB CSV in ~2s. Charts on 100k+ rows are just live.

This has been the state of things long before LLMs, and companies still hired and trained up juniors, only to see them leave after 18 months.

But that's fine. The junior you trained up will be more effective at their next job, and the junior your competitor trained up will be more effective when you hire them at your company. Again, that's how it's been for far longer than we've had LLMs.
Online debate in US is botted
by vinserello | 2025-10-01 07:49:00+00:00
As soon as we launched our app on an online directory, we were overwhelmed by thousands of bots spamming “TRUMP2028”, followed by a DDoS attack. Our app is a stupid fast 1v1 debate platform judged by AI called Debatable. We built it thinking of dialectic debating, but we were not expecting this. Thanks to AppCheck and Vercel AntiBot Firewall, the platform survived, but hundreds of users and debates had already been created.

It’s a wild first stress test. But how can US survive to this level of debate-contamination?

I don't suggest the problem is that the hardware can't be "pushed and used", the problem is that the hardware is being artificially limited by Apple for some unknowable reason. (Well, the reason is knowable, but I'm sure some would dispute it anyways. It's very clearly an extreme defense of their 30% cut on all software that runs on iOS devices.) This is not a question, it doesn't matter what people are doing with iPads, it really is happening. A good example, the first iPad with hardware virtualization support in its CPU could initially run VMs provided you had a jailbreak, but then Apple entirely removed the virtualization framework from the following iPadOS update.

There is no particular reason a general purpose computer should be "not for me specifically" in terms of what you can do in software. In terms of design, sure. But not in terms of what you can do in software.

(I have a suspicion the same reason is responsible for why you basically don't find open source software on iOS devices the way you would on even Android or Windows; it doesn't make any money to take a cut out of.)

Lack of spine? Or is it just lack of substance? Lack of credibility? Lack of talent? Lack of focus on the issues that people actually care about? Lack of leadership? Lack of a real true grass roots base?

The Democrats are basically in complete shock right now and probably realizing that they’re gonna have to rebuild the entire party. I fail to see anyone at this point in time within the Democratic party that is capable of taking the reins that has any charisma or plan that really addresses the key issues that most Americans care about.

The only bright spot (as far as liberal media seems to be determined) for the Democrats seems to be a young upstart mayoral candidate in a large American city who they don’t even support.

In my latest company we made a bash script called "run". We put a bunch of commands in there like "setup", "download-certs", "deploy-staging", "deploy-prod", "fix", "test"

so you run like this:

./run setup

And all the commands can be listed by running:

./run

If I wanted a chart the command could spit out a png somewhere and tell you about it.

There are no dependencies to run the script, and if any of the commands needed dependencies you could just put them in setup and call setup from a commmand.

The difference is Hegseth is an uncouth, unqualified stooge who renamed the Department of Defence to the Department of War. And if you're going to sit here and try to justify war when they are adversarial to our allies and claiming we have "enemies within" in reference to a nonexistent radical left, then it is very different. The war in this context matters, or have we lost nuance?

I don't agree with JFK's continuation of war in Vietnam, so fuck him, too. It also seems like you're twisting yourself a bit to equate Gerald Ford's sentiment, but hey, that's just my opinion, man.

Steelmanning? It's infinite content, meaning our customers will never run out of new and interesting videos to watch, which will inspire them to feed prompts into our systems too and have it generate more videos. Money can be generated from multiple angles; we can charge a premium for generating videos beyond a small free tier once we've hooked the prompters, we can offer people or companies the option to promote their own videos so they get put into people's feeds, and we can insert generated ads from big corporate sponsors. It'll be lit.

Why should a commercial enterprise that has had billions of investments have benefits outside of earning money? Besides the entertainment value that the masses get from making and viewing these, of course.

To me the one that sticks out the most is:

but the primary use of the site should be for curiosity.

HN sometimes feels more promotional and like an extension of /r/apple and people playing silicon valley sportsball.

I like the posts about curious things, not so much press releases, new product announcements, and people carrying water for trillion dollar companies. I don't exclude myself from this, my high horse is a donkey on stilts.

Masses are weak and dumb. It is the law of averages. If split apart because of minor factors such as a race, genre and etc, the forces cancels out and no one works together. Can you think in a modern type of media that exactly does that?

It takes to much effort to get people out of inertia. Powerful people, au contrarie, work together. They same places, same parties, have same connections, their kids go to the same schools. They might compete, but they defend the same gray areas in politics, law and etc.

Gray areas are there because that's what put apart rich people from poor people. "How expensive is your lawyer" defines how much you can abuse the system.

So i'm nodding along with most of this, but I don't understand how they can say something as strange and obviously nonsensical as this:

>The incentive for it to happen suddenly is that, even if Nakamoto's fix were in place, someone with access to the first sufficiently powerful quantum computer could transfer 20% of all Bitcoin, currently worth $460B, to post-quantum wallets they controlled. This would be a 230x return on the investment in PsiQuantum.

Thats some really bad accounting on the incentives and ROI available. You can't just start selling and expect the price to be stable.

But it does bring up a secondary question I've never seen any numbers on; How much money could you possibly make if you knew for certain the value of bitcoin magically went to 1% in a panic sell?

Are there any institutions open to selling a billion dollar put option?

I am positive there's a sub-arc in bad history/religion dedicated to historical figures with less extant evidence than a certain jew in Palestine, recorded by Josephus 60 odd years after his passing, but for who we retain confidence they exist (noting that curing scrofula aside, kings weren't generally worshipped as gods, although some were sanctified)

There's also a version of Oscar Wilde's quip from "the importance of being Ernest":

"To lose one King, Mr. Worthing, may be regarded as a misfortune; to lose two looks like carelessness".

But I guess we'll have to wait for another lost English king to surface.

Artemis/Apollo are mentioned in the post above - yeah they work better than the out of box experience, but you still have to configure your physical screen to be off for every virtual display. It unfortunately only runs on Windows and my machine usually doesn't. I also only have one dGPU and a Raphael iGPU (which are sensitive to memory overclocks) and I like the Linux gaming experience for the most part, so while I did have a working gaming VM, it wasn't for me (or I'd want another GPU).

> The existing seniors in your team will enjoy working with smart and motivated developers.

Maybe I just suck, but as a senior I've rarely enjoyed working with junior developers, even the earnest ones who really wanted to learn. I always had a ton on my plate, and mentoring juniors didn't replace anything from that ton of work, it just added to it.

And yes, I get that mentoring juniors is useful and essential. But companies need to build that into the job, not build it on top of the job.

FYI the images are not generated based on the WiFi data. The WiFi data is used as additional conditioning for a regular diffusion image generation model. So what that means is the WiFi measurements are used for determining which objects to place where in the image, but the diffusion model will then fill in any "knowledge gaps" with randomly generated (but visually plausible) data.

IIRC Dwork and Naor's work had a trapdoor (which the server used to cheaply validate the challenges) and would be unsuitable for any kind of decentralized public system. It's not "proof of work" in the same sense, or arguably proof of work at all to anyone but the server and parties that trust them.

Look, Duolingo is obviously not the only thing you use to become proficient in another language. It's not perfect, it's gamified, it's over simplified - it's a tool in the toolbox.

That being said, it's helped me immensely with both polishing my Dutch (I passed my state exams a while back but there are still so many words I don't know), and I'm now learning Japanese.

Yes, Duolingo does not teach you directly all the intricacies of Japanese grammar. That's because it's a dumbed down, spaced repetition app. If you're actually serious about learning a language you'll see that pretty much from the start and like, buy some Japanese textbooks or something to supplement what you learn from the owl app.

I'm currently using Satori Reader and have bought a manga to practice my Japanese reading. My grammar is still woeful, so I'll need some other material to work on that and get a real understanding.

Anyway, I don't really disagree with the author on their criticism per se. But I think the criticism applies to a bunch of language learning methods...

> The crisis part is that I can't justify this belief with words.

Here's one attempt; it's art versus content. Tiktok is content; it's people recording a video, sometimes in one take and publishing, sometimes in multiple takes with some editing etc, sometimes fully professional ones. But overall, it's cheap, rapidly produced content for cheap, rapid consumption. ASoIaF was a labor of years to produce not just a series of books, but a world, a rich history, and later on a multi-media enterprise that involved and employed millions of people, then entertained and excited hundreds of millions of people over the years.

AI is lowering the barrier to entry even more, with anyone able to just punch in some words - less even than this comment - and produce something. For someone to consume. Maybe one in a billion will be remembered or still popular in a decade (like how some of these cheap videos are still popular / remembered / quoted, think vines / memes). But the ratio just keeps getting worse.

ASoIaF to a TikTok video is like... ASoIaF to a tweet.

The picture of the top is of the tape readers for the Harvard Mark I, from 1944. It's Peak Tabulating Machine, a reasonably general purpose automatic computer built from IBM tabulating machine parts. The project started in 1939, but was held up by WWII.

IBM's early computing history was a long struggle between what people wanted to do and what could cost-effectively be built.

Yeah, I think that's fair.

On the other hand, I think it's really cool to teach laypeople about things like "sizes of infinities", etc. They are deep math concepts that can be taught with relatively simple analogies that most people understand, and they're interesting things to know. I know that I personally loved learning about them as a kid, before I had almost any knowledge of math - it's one of the reasons that while I initially didn't connect with other areas of math, I found set theory delightful as a kid.

I just feel like if you need to first walk people through a bunch of philosophical back and forth on constructionism, you'll never get to the fun stuff.

Sadly, the time to get involved was a while ago.

At this point, the root cause analysis leads to a highly efficient right wing media scape. Efficient because it’s given up on accuracy, and optimized on narrative effectiveness. Trump has a 60%+ approval rating amongst republicans right now, down from 77 in June July (iirc) and even higher in march.

There is no healing a wound, if the source of aggravation is constantly present.

It is also hard to categorize it as a wound, if all Fox and the right media ecosystem is doing, is simply exercising their right to free speech. They just happen to be in lock step with their party, and they’ve spent decades aiming to fill seats, and ensure bipartisan leaning politicians get ousted.

None of this is obviously wrong or illegal, it’s simply focusing on the rules as opposed to the spirit and the norms.

They are “winning”, against science, norms, public opinion and more.

This is the mountain that has to be climbed, and most people are still under the impression that this is business as usual, or that this is simply the pendulum of history moving in the opposite direction.

These days it's easier to write hardware accelerated terminals than CPU bound ones simple because of the system libraries available for drawing to a blank canvas. That is, unless you're using a web wrapper (eg Electron), but then you'd bet Electron is using GPU acceleration under-the-hood too.

I say this as someone who's written my own terminal emulator too. SDL was a natural choice, not because of GPU acceleration, but because it gave me the APIs I needed for rendering a terminal.

The other ironic thing about all these terminal emulators that advertise themselves as being "GPU accelerated" is that text rendering cannot be GPU accelerated. Or at least the only way I know of to render text to the GPU is to first render it using the CPU, then push that bitmap to the GPU memory. This leads to developers having to create a "font atlas", which is basically a bitmap with all your characters already cached in GPU memory. And thus you either need to cache the entirety of Unicode, including alternative glyphs due to variation selections, different font characteristics (bold, italic, etc), and even different font colours (if you want nice anti-aliased fonts ;) ). Which means you then need to software render a bunch of stuff on demand anyway, because otherwise you're basically caching every imaginable character and combination on start up.

So yeah, I don't think "GPU accelerated" is the same flex it used it be.

I feel that this is a data collection activity (and thus, more advanced future models and usecases) disguised as a social media. People will provide feedback in the form of clicks/views on AI generated content (better version of RLHF) on unverified/subjective domains.

Biggest problem OpenAI has is not having an immense data backbone like Meta/Google/MSFT has. I think this is step in that direction -- create a data moat which in turn will help them make better models.

I'm sorry but this post is highly biased and serves as gaslighting in its own way, just for a different crowd. I don't know if it's deliberate or not, but it's very telling that it's on HN frontpage.

There's no mention of:

- The lightning network (bitcoin-native layer 2 enabling near-instant transaction speed)

- Role of mining in grid stabilisation, methane reduction, etc.

- How mining hardware is actually used by miners when cost of energy is nearly free.

- Bitcoin's difficulty adjustment algorithm

- Protocols like Cashu (Chaumian Cash based on Bitcoin)

And one last thing. Mixing in a big bag "crypto" and "bitcoin" is in itself just a very bad take. sigh.

As a side note, I highly recommend Lyn Alden's book Broken Money.

Are you sure?

Back in late 90s, 2000s, even 2010s, the internet was truly awesome. Only once governments started to get involved, by increasing the red tape and adding restrictions and whatnot, it became shit.

So I would argue that you are completely wrong. Yes, it might have been a bit of a wild west, but that is a good thing because you needed to have some smarts to navigate it and that filtered out the dumb masses that pollute it today and why we cannot have nice things.

I am not saying people should not have access to it, just that the less people there were, the better it was and the less attention it had by the governments. Which in turn made it much better experience than it is today.

But most people, actually, have not lived through those "early" days and cannot even comprehend how great it was back then and how crappy and restricted it is today.

The Democrats are pushing to continue more generous federal subsidies to help Americans afford Obamacare policies and to reverse deep cuts to Medicaid contained in Trump’s sweeping domestic policy agenda package. But neither of those changes would provide health coverage to undocumented immigrants, since they aren’t eligible for either program.[1]

The AoA failure logic does not allow for manual reversion of the master/monitoring FCC. It still requires cross-checking sides in the event of an AOA DISAGREE annunciation. But since the update, MCAS is disabled in this scenario. As far as the FMC, the relationship between AoA vanes, flight control computers and CMD A/B is not configurable. But the non-failed autopilot channel can be selected.

> The government and civil service are also incompetent to the extreme.

As someone who moved to the UK from the states recently, this has not been my experience at all. Any paperwork i've had to do with the government (immigration, NHS, drivers license, car tax) has been incredibly smooth. On top of that, the city council in the area I live seems great -- they put on a ton of events, and have lots of services that seem to get used well.

Most of the incompetence i've seen is from private companies (e.g. banks and real estate).

GPU accelaration has become so common for new terminals nowadays, that I can't see the point in making that a headline feature. To be fair, the homepage has a more generic tagline ("A modern terminal for the 21st century") and a list of items. My problem is that these bullet items also don't say very much:

24-bit color is even more ubiquitous than GPU acceleration. Apparently even the builtin macOS Terminal will support 24-bit color in Tahoe, and I think Windows Terminal has been supporting that since it was released (which is more than 5 years ago). Even image support is kinda old news: many terminals support at the very least Sixel or the iTerm image protocol. Ligatures and splits are also quite common.

It would be more interesting if we started comparing terminals by the details of these features, since the devil really is in the details. For instance, not all image protocols are made equal. Sixels are very slow, while the iTerm protocol is quite limited - you have very little control on where the image is placed. The Kitty Graphics protocol is the most advanced protocol, but there are two different image placement methods: positioning, unicode placeholder and relative to other images. Besides that there are a couple of other features such as animation and communicating back with the terminal to get image IDs. I've seen several terminals claiming to have Kitty Image Protocol support, but I've never seen any of them put out a matrix of which features they support (other than Kitty that obviously supports everything).

The Kitty Keyboard Protocol is also another thing that is quite complex and I've ran into issues in the past with both iTerm and WezTerm behaving differently than Kitty and running into trouble with some programs which expected the kitty behavior.

I learned english at school in France, and we're notoriously bad at teaching foreign languages. The approach is way to academic and mainly based on reading. That's why our accents are often atrocious. I was good at written tests, but what allowed me to actually get fluent (as in being able to think in english and convert my thoughts to speech in real time) was watching tv series in english with subtitles in english (no translation involved.)
