You can (partially) blame Microsoft for that. I still don't understand why it's seemingly OK for device manufacturers to distribute such crapware through Windows update. New keyboard? Oops, spyware. Printer on your LAN? Here, let me install these 16 utilities for you. Just give me a driver without any GUI tools. Or at the very least prompt me before installation.

I had to check the precise definition for trigonometry while writing my comment, found it interesting so I added a reference.

As with many subject that we learn early in school, it's often interesting revisiting them as adult to perceive additional layer of depth by casting a new look.

With trigonometry we tend to associate it with circle. But fundamentally it's the study of tri-angles.

What is interesting is that the whole theory is "relative". I would reference the wikipedia page for angle but it may make me look like an LLM. The triangle doesn't have positions and orientation baked-in, what matters is the length of the sides and the angle between them.

The theory by definition becomes translation and rotation invariant. And from this symmetry emerge the concept of rotations.

What is also interesting about the concept of angle is that it is a scalar whereas the original objects like lines live in an higher dimension. To avoid losing information you therefore need multiple of these scalars to fully describe the scene.

But there is a degree of redundancy because the angles of a triangle sums to pi. And from this degree of freedom results multiple paths to do the computations. But with this liberty comes the risks of not making progress and going in circles. Also it's harder to see if two points coming from different paths are the same or not, and that's why you have "identities".

Often for doing the computation it's useful to break the symmetry, by picking a center, even though all points could be centers, (but you pick one and that has made all the difference).

Similar situation arise in Elliptic Curve Cryptography, where all points could have the same role, but you pick one as your generator. Also in physics the concept of gauge invariance.

I don't think that's a true etymology of "bucket shop," which per my recollection of Livermore was just an off-track-betting parlor for ticker symbols, but where nobody actually bought the shares (bundled or otherwise). Strictly a retail swindle, having nothing directly to do with the risk/maturity bundling work you are criticizing above.

The mechanism behind why more fiber helps is pretty straightforward:

Insoluble fiber speeds up gut motility. Faster gut motility means less time for toxins to sit and absorb in your gut.

Also, fermentable fibers serve as substrate for gut microbes, producing short-chain fatty acids (butyrate is one - a primary fuel source for colonocytes - the cells that line your colon).

It also lowers colonic pH, inhibiting pathogenic bacteria.

Lastly, (although there are tons more benefits I'm not listing), soluble fiber is incredible for people trying to lose weight, as highly fibrous foods increase satiety, keeping you fuller for longer.

Your question hits directly at latency vs. throughput distinction. Depends on which you mean by "fast."

Throughput-wise, the supercomputer is competitive because it has a lot of local RAM connected to lots of independent nodes, which, in aggregate, is comparable or exceeds modern M1's RAM throughput, let alone disk. Latency-wise, old RAM still beats NVMe by two or three orders of magnitude.

Heh. Today I found thanks to the 9front people that some GB games used carts' sram as 'swap'.

games/gb didn't save the sram in the emulator save files, so upon restoring the snapshot and saving in the cartridge memory you got a mismatch. It got fixed really fast, the emulators are really simple plan9 C compared to anything else.

Look, ukraine's economy is destroyed, the men are either dead, disabled, or have fled, and the ones who haven't are being kidnapped off the street to be pressed into service, the grid has been set back by decades, they're deep deep in debt, and everyone knows they aren't getting the mineral-rich east back. It's beginning to look doubtful if they can even keep their black sea port. They have under half the population now than they did when the soviet republic collapsed (granted, mostly due to circumstances unrelated to the war—notably, outmigration.)

So perhaps I was being a bit of a dick by calling Lviv polish, but it will probably take ukraine decades, maybe a century or more, to recover from this devastation, even if against all odds they manage to enforce their absurd demands that russia withdraw. It does matter to a nation to keep its historic lands, and ukraine has already lost about half of all traditionally ukrainian land + crimea. Far western ukraine, including Lviv, has only been considered "ukraine" for a little over a hundred years.

> but hasn't ChatGPT had capability to create graphs and interact with data for a while?

It's pretty bad (for me). I have to use extremely prescriptive language to tell ChatGPT what to create. Even down to the colours in the chart, because otherwise it puts black font on black background (for example). Then I have to specifically tell it to put it in a canvas, and make it interactive, and make it executable in the canvas. Then if I'm lucky I have to hit a "preview" button in the top right and hope it works (it doesn't). I could write several paragraphs telling it to do something like what Claude just demo'd and it wouldn't come close. I'm trying Claude now for financial insights and it's effortless with beautiful UX.

For posterity, Gemini is pretty good with these interactive canvases. Not nearly as good, but FAR better than ChatGPT.

A bit more context on the idea.

Spreadsheets already behave like a computational graph - cells referencing other cells.

If you've ever built a financial model, you know the feeling: changing a few assumptions recalculates the entire workbook across many sheets.

MetaCells explores extending this pattern with AI processing. Some cells can call models, process documents or receive/send data through connectors.

The interesting part is that the whole reasoning chain becomes visible directly in the sheet, which reduces the mental overhead compared to many agent frameworks.

> copyright governs copies, it doesn't govern ideas or algorithms

The second part is true. The first is a little trickier. The copyright applies to some fixed media (text in this case) rather than the idea expressed, but the protections extend well beyond copies. For example, in fiction, the narrative arc and "arrangement" is also protected, as are adaptations and translations.

If you were to try and write The Catcher in the Rye in Italian completely from memory (however well you remember it) I believe that would be protected by copyright even if not a single sentence were copied verbatim.

> One sign that marathons (let alone ultramarathons) may not be particularly healthy is that the first guy to do one famously died, and then subsequently people die doing them every single year

I don't find this line of thinking terribly convincing

It's well known that (even young) elite athletes with unknown inborn heart defects sometimes die after extreme exertion. But it doesn't really follow that "extreme exertion is bad for you," the lurking variable is the heart defect.
Show HN: BugStack – Autonomous error fixing that ships to prod while you sleep
by Bugboy | 2026-03-12 17:40:25+00:00
Hey HN,

bugstack started life as an internal tool for my other startup Fuelscout because my customers would encounter production bugs when I was away that would ruin their experience. When I went camping and came home to find out my internal tool had fixed an error and shipped it to production I knew it was bigger than Fuelscout, so my little tool became bugstack.

bugstack monitors your production errors 24/7. When a user hits a bug, bugstack captures the error, pulls context from your repo, generates a minimal surgical code fix, runs it through CI, and delivers it as a pull request. If your CI passes and the fix meets your confidence threshold, it can auto-merge — or you can review the PR yourself.
The workflow is: Capture → Fix → Deploy.

Technically:

You install an SDK (npm install @bugstack/sdk) and init with an API key
Errors get fingerprinted for smart deduplication (no duplicate PRs for the same bug)
The AI analyzes root cause using your actual codebase as context, then generates minimal diffs — not giant rewrites
Fixes are syntax-checked, scope-checked, and committed to a new branch with a detailed PR
Each project has independent confidence thresholds and you choose manual review vs. auto-merge
Dashboard tracks the full lifecycle: Pending → Building Context → Generating Fix → Testing → Fix Ready → Auto-Fixed

Supports JavaScript (Express, Next.js), Python (Flask, FastAPI, Django), Ruby (Rails), and more.
14-day free trial.

I'd love feedback from anyone who deals with on-call rotations or production error triage. What would make you trust an AI to fix your prod bugs?

> Dean Ball made this exact point on the Ezra Klein show a few days ago. I always thought laws would get more just with perfect enforcement -- the people passing mandatory sentencing laws for minor drug offenses would think twice if their own children, and not just minorities and unfavourable groups, were subject to the same consequences (instead of rehab or community service).

The problem with perfect enforcement is it requires the same kind of forethought as waterfall development. You rigidly design the specification (law) at the start, then persist with it without deviation from the original plan (at least for a long time). In your example, the lawmakers may still pass the law because they don't think of their kids as drug users, and are distracted by some outrage in some other area.

You can control your luck a bit though. Granted you could be in perfect health but roll a 1 five times in a row and get a heart attack when you are 40. Or you could be crushing junk food and alcohol but you just keep rolling 6s and make it to 80.

If you look at the sequence of events that happen to trigger a heart attack, it becomes really clear how big a role luck is, but still you can mitigate each step. Studying this stuff also makes your body seem like a walking time bomb.
Show HN: An application stack Claude coded directly in LLVM IR
by dboreham | 2026-03-12 17:41:15+00:00
This repo is the result of a debate about what kind of programming language might be appropriate if humans are no longer the primary authors. Initially the thought was "LLMs can just generate binaries directly" (this was before a more famous person had the same idea). But that on reflection seems like a bad approach because languages exist to capture program semantics that are elided by translation to machine code. The next step was to wonder if an existing "machine readable" program representation can be the target for LLM code generation. It turns out yes. This project is the result of asking Claude to create an application stack entirely coded in LLVM's intermediate representation language.

I don't know about Italian law, but in the US tax evasion is pretty difficult in many cases to prove. It is illegal in the US to deliberately defraud the IRS to evade paying taxes, it is not illegal to make a mistake, or claim a deduction you think you can claim when the IRS decides you can't, etc. So prosecutors must prove you had an intent to evade taxes you knew you owed. Because they can rarely meet that bar, criminal charges are rarely brought.

> Speed, cost, security, job/task management

All of that will inevitably be solved.

50 years ago, using a personal computer was an extravagant luxury. Until it wasn't.

30 years ago, carrying a powerful computer in your pocket was unthinkable. Until it wasn't.

Right now, it's cheaper to run your accounting math on dedicated adder hardware. But Llms will only get cheaper. When you can run massive LLMs locally on your phone, it's hard to justify not using it for everything.

... in mice. So if any of this held in humans, I think you'd see reversal of old-age memory problems in people treated with antibiotics that kill Parabacteroides goldsteinii.

As far as I know, no such effect has been observed.

And this article claims inflamation from that strain, the NIH claims otherwise: "Parabacteroides goldsteinii
is a next-generation probiotic gut bacterium with significant anti-inflammatory and metabolic benefits, often reduced in obese or diseased states. "

I think this site is either satire, or serious but with a certain kind of humor in which both they and the reader know they're lying (but it's in everyone's interest to play along).

They do say this:

> Is this legal? / our clean room process is based on well-established legal precedent. The robots performing reconstruction have provably never accessed the original source code. We maintain detailed audit logs that definitely exist and are available upon request to courts in select jurisdictions.

Unless they're rejecting almost all of open source packages submitted by the customer, due to those packages being in the training set of the foundation model that they use, this is really the opposite of cleanroom.

These lens "blockers" are working less-and-less well (as tech gets better if they ever worked well at all), and seem to increase targeting from law enforcement.

In Tennessee, after the first two citations for "improper display of registration" it becomes an actual crime (an actual misdemeanor); if I ever get to this point (four months now multiple cops behind me haven't given a single F), I have an increasingly-insane series of "protests" that have semi-interesting legalities [0].

[0] e.g. transfer registration to brother ($10 gift fee every few months, which results in no tag requirement); small 3ft trailer (possibly with guillotine erected atop, blocking view), as TN does not issue license plates to trailers less than 15ft length

This isn't about "disappearing" (impossible in any modern civilization) — it's about sending a message and adding one small additional layer of protection from simple broad ALPR searches.

I think you're overestimating the complexity of small unmanned subs. Drug traffickers are building _manned_ subs now in South American jungles.

You just need a body (plastic tube), batteries, motors, and a computer. Maybe with a "range extender" gas engine. Everything can be COTS, and Iran certainly can manufacture occasional custom components.

After all, it can manufacture centrifuges for uranium enrichment.

So taxpayers are on the hook for their sugary drinks, probably high fat/sugar foods that have almost no nutritional value. We have a diabetes and morbidly obese epidemic.... and most likely if you are on SNAP the taxpayers are also paying for your healthcare.

Makes zero sense to me.

Oh great, another method to make screen readers and keyboard navigation impossible.

At this point, bots are better at getting data out of web pages than people are. (And have been so for at least a few years: https://www.usenix.org/conference/usenixsecurity23/presentat...)

All we're doing now is making it easier to get data from a web scraper than to browse to the web page ourselves.

This is really cool -- pedantically, I've always thought "full spectrum" is actually misleading from a traditional photographic sense. Like IR + visible light + UV != full spectrum. I'd love to see post-processed imagery of every-day life through an extended view of broader EM energy (similar to astrophotography)... like what does a city scene look like with x-rays and microwaves included?

Side note: have always loved this image https://imgur.com/NZjWfWT of rainbows with UV and IR visible.

I worked on building blockchains for about 4 years, and this is not a stupid question at all. The verification problem is real. A 5-minute training run produces an objective val_bpb score that anyone can reproduce from the published source code. And this is actually valuable work, unlike most proof of work chain workloads.

The practical challenge is that adding a blockchain means agents also need to participate in consensus, store and sync the ledger, and run the rest of the network infrastructure on top of the actual research. So it needs a unit economic analysis. That said, all results already include full source code and deterministic metrics, so the hard part of verifiable compute is already solved. You could take this further with a zkVM to generate cryptographic proofs that the code produced the claimed score, so nobody needs to re-run anything to verify. Verification becomes checking a proof, not reproducing the compute.

Compute-credits are interesting. Contribute GPU time now, draw on the swarm later for training, inference, whatever you need. That's a real utility token with intrinsic value tied to actual compute, not speculation.

> My comment is that it is not ONLY low fiber diets.

Well, you said "can't" and I asked "why", which feels very reasonable to me. Your argument seems to be that it wouldn't account properly for the data - specifically, you're saying we would have seen colon cancer rates rise earlier.

> Western diet collapsed its fiber intake well over 80 years ago - it would have shown up already.

I don't really buy this for a lot of reasons. Probably the two most important are (a) ability to screen historically and (b) the timing isn't particularly "off" for the fiber argument. We did see it already, we've been seeing increases in color cancer risks for decades.

Now, I'm not married to it "just" being fiber whatsoever, but if I were to "bet" on the major contributing factor, naively, that's where my money would go. I think it's very reasonable to not place your bet there.

My experience with posted rules is that it's less about people following them preemptively than having an explicit reference to point to when they don't.

HN's long-standing policy has been to fewer explicit rules, and looser rather than stricter interpretation. This particular one comes up often enough though that it's helpful to retain IMO, thanks for restoring the cut.

I've long made a practice of linking to moderator comments regarding policies when calling out deviations, as I'm sure the mods are aware, others might find that helpful. I've found it generally reduces the personal-irritation element going both ways, helps avoid derailing threads, and serves as a refresher to me on what standards apply.

I just want to link this teardown; it is a suitable companion to this article:

On a rational level it isn't surprising that the "compute" part is so small, given its origins, but for some reason it still caught me by surprised seeing something barely larger than a Raspberry Pi.

But, yeah, this thing is crazy modular. I particularly want to call out how trivial it is to replace the ports, given how common of a failure point they are. With the keyboard/monitor being more involved, but absolutely still approachable.

I never managed to get Fusion 360 running reasonably on Linux, in the end I switched CAD software. It really needs some sort of reasonable OpenGL support (or maybe DirectX, I forget which it was). And it doesn't work under wine, it did at some point but then it stopped. Cloud connected software, so you can't just run an old version.

Maybe if you had a second GPU and forwarded it to the VM? Not willing to spend that extra money, and it would only work on my desktop, not my laptop.

SQL injection is prevented by using database APIs properly, not sanitizing. Put all the malicious SQL you want in a query string, if it's passed as a bound parameter to a prepared query, it's only ever going to be a plain string.

You might sanitize for different reasons like business logic, but if it's your first line of defense against sql injection, you're already on the losing side.
Show HN: Baltic security monitor from public data sources
by makefunstuff | 2026-03-12 17:44:25+00:00
People around me started repeating stuff from various psyop campaigns on TikTok or other social media they consume.

Especially when living in Baltics it's basically 24/7 fearmongering here from anywhere, either it's constant russian disinfo targeted campaigns via their chains of locals or social media campaings or some bloggers chasing hype on clickbait posts, so it was driving me mad, and it is distracting and annoying when someone from your closest ones got hooked on one of these posts and I was wasting time to explain why it was a bs.

So I took my slopmachine and some manually tweaking here and there and made this dashboard. Main metric is basically a daily 0-100 threat score, which are just weighted sums and thresholds - no ML yet.
