Most of the logic can be reused, but the FP64 multiplier is up to 4 times larger. Also some shifters are up to 2 times larger (because they need more stages, even if they shift the same number of bits). Small size increases occur in other blocks.

Even so, the multipliers and shifters occupy only a small fraction of the total area, a fraction that is smaller then implied by their number of gates, because they have very regular layouts.

A reduction from the ideal 1:2 FP64/FP32 throughput to 1:4 or in the worst case to 1:8 should be enough to make negligible the additional cost of supporting FP64, while still keeping the throughput of a GPU competitive with a CPU.

The current NVIDIA and AMD GPUs cannot compete in FP64 performance per dollar or per watt with Zen 5 Ryzen 9 CPUs. Only Intel B580 is better in FP64 performance per dollar than any CPU, though its total performance is exceeded by CPUs like 9950X.

Had the same thought reading this. I haven't found a place for LLMs in my writing and I'm sure many people have the same experience.

I'm sure it's great for pumping out SEO corporate blogposts. How many articles are out there already on the "hidden costs of micromanagement", to take an example from this post, and how many people actually read them? For original writing, if you don't have enough to say or can't [bother] putting your thoughts into coherent language, that's not something AI can truly help with in my experience. The result will be vague, wordy and inconsistent. No amount of patching-over, the kind of "deslopification" this post proposes, will help salvage something minimum work has been put into.

The real question is unification vs bidir more than HM vs bidir.

Unification is simple, not very hard to implement and more powerful.
Bidir gives better error messages and is more "predictable".

I personnaly lean strongly towards unification. I think you can get good enough error messages and what you lose with bidir is not worse it. But clearly the Rust core team disagreed. They clearly don't mind annotations.

Anyway, here is my non answer: it's a trade off.
Show HN: Schema Sentry – Type-Safe JSON-LD for Next.js with CI-Grade Validation
by arindamdawn | 2026-02-19 11:05:19+00:00
TL;DR: I built a tool that makes adding JSON-LD structured data type-safe, validates against actual HTML output (not just config files), and enforces it in CI. No more broken schema markup.

The Problem

JSON-LD is painful to manage:

- Manually writing JSON-LD is error-prone and tedious

- Schema breaks silently when content changes

- Other tools validate JSON files (false positives!) — your pages still lack markup

- AI systems (ChatGPT, Claude, Perplexity) can't cite your content without proper structured data

- 30% lower CTR without rich snippets in Google

The Solution

Schema Sentry gives you type-safe builders + CI validation:

// Type-safe schema with autocomplete

*
import { Schema, Article, Organization } from "@schemasentry/next";

export default function Page() {

return (
<>
<Schema data={[
Organization({ name: "Acme", url: "https://acme.com" }),
Article({
headline: "My Post",
authorName: "Jane",
datePublished: "2026-02-18",
url: "https://acme.com/blog/post"
})
]} />
<main>...</main>
</>
);

}

Then in CI:

*
pnpm schemasentry validate --manifest schema-sentry.manifest.json --build
*

This validates actual built HTML — catches missing schema that other tools miss.

Key Features

- Type-safe builders for 15+ schema types (Product, Article, FAQ, etc.)

- <Schema /> component for Next.js App Router

- Validates real HTML output (zero false positives!)

- Manifest-driven coverage enforcement
- GitHub Bot for automated PR schema reviews
- VS Code extension with live preview

Why This Matters

- SEO: Eligible for rich snippets (30% higher CTR on Product pages)

- AI Discovery: ChatGPT/Claude/Perplexity can cite your content

- CI-grade: Fails builds when schema breaks — never deploy broken markup again

Try it:

pnpm add @schemasentry/next @schemasentry/core

pnpm add -D @schemasentry/cli

pnpm schemasentry init

Would love feedback!

I wanted to build an easy to self host old myspace style app that is connected to the fediverse - it took me a while to figure out how activity pub is actually meant to work and what the challenges are to be a fediverse citizen. I thought it could be useful to write it down, sitting somewhere in between the detailed activity pub specs and the high level wikipedia description.
Show HN: What We Learned: a 3 question meeting closure tool
by anticlickwise | 2026-02-19 11:06:03+00:00
I built this because I kept seeing the same thing happen. A meeting would end, everyone would feel aligned and we’d move on. It felt productive. But a few weeks later, the same misunderstandings would show up again.

It wasn’t that people weren’t paying attention. We just never paused long enough to capture what we learned while it was still fresh. Retros felt too heavy for everyday decisions. Shared docs didn’t really solve it — the first person to write would shape everyone else’s answer.

So I made something intentionally small.

At the end of a meeting, it asks three questions:
– What worked?
– What didn’t?
– What should we remember next time?

Everyone answers independently, then you see a shared snapshot. No accounts, no scoring, no task generation. It’s just a short pause before moving on. Curious if others have run into this, or solved it differently.

> Companies don't need "more work" half the "features"/"products" that companies produce is already just extra.

At my company we have a huge backlog where only the top of that iceberg is pulled every iteration to keep customers happy.

If they fired 90% of the engineers assuming a 10x increase in productivity, they might be able to offer their product at half the price. But if they keep all their engineers they'd get 10x the features and could probably charge twice as much for it.

Web scraping for LLMs has almost completely ruined the search experience. In the past I could search for simple questions, and quickly get an answer without even having to click through to the links.

This was horrible for web traffic, but the utility level was off the charts. It was possible to get accurate results in milliseconds. It was faster than using an LLM.

Now sites put almost no info in the search result headers, to get people to click through. I think this will work on some users, but most will start using LLMs as search by default.

Search engines have gotten so bad that I almost feel forced to try running SearXNG or some other search engine locally. Its a pain to set up, but degooglefication is always worth it.

> How come a graphics powered REPL is less capable than a window that pretends to be a tty from the 1970's?

I mean the Smalltalk transcript and its capabilities alone, not Smalltalk as a whole. The transcript apparently just logs plain text; xterm supports color and text formatting like bold and italic. I'm guessing that, per https://news.ycombinator.com/item?id=47058849, you'd want fancy text displayed separately in the GUI.

"Please write me some documentation for this code. Don't just give me a list of bullet points. Make sure you include some context. Don't include any icons. Make sure the text flows well and that there's actual reasoning. Don't include comments about changes made during development that are irrelevant to the final work. Try to keep it concise while respecting these rules."

I think many of the criticisms of LLMs come from shallow use of it. People just say "write some documentation" and then aren't happy with the result. But in many cases, you can fix the things you don't like with more precise prompting. You can also iterate a few rounds to improve the output instead of just accepting the first answer. I'm not saying LLMs are flawless. Just that there's a middle ground between "the documentation it produced was terrible" and "the documentation it produced was exactly how I would have written it".

Not sure what the problem is, I am on Max and use Claude Code, never get usage issues, that's what I pay for and want that to always be an option (capped monthly cost). For other uses it makes sense to go through their API service. This is less confusing and provides clarity for users, if you are a first party user use Claude's tools to access's the models otherwise API

Difficult to put a thesis on a road sign, but in general people make mistakes when building a business:

i. desperately grasping at low hanging fruit in a fragmented market. Where people burn enormous amounts of cash to bid down their own sectors perceived value.

ii. trying to innovate their way out of a bad business plan, instead of studying the market for what folks actually wanted.

iii. cognitive offloading, and premature labor cost-minimization using LLM isomorphic plagiarism to poison public discourse

The GP assumes that an LLM is able to write such novel. So I was working from there. My thesis is that even IF LLMs are able to produce "novelty", it will become the norm and we will simply demand even more exotic novelty.

> An interesting thought experiment is whether it's possible that AI tools could write a novel that's better than War and Peace. A quick google shows a lot of (poorly written) articles about how "AI is just a machine, so it can never be creative," which strikes me as a weak argument way too focused on a physical detail instead of the result. War and Peace and/or other great novels are certainly in the training set of some or all models, and there is some real consensus about which ones are great, not just random subjective opinions.

I think I've made two good decisions in my life. The first was switching entirely to Linux around '05 even though it was a giant pain in the ass that was constantly behind the competition in terms of stability and hardware support. It took awhile but wow no regrets.

The second appears to be hitching my wagon to Mistral even though it's apparently nowhere as powerful or featureful as the big guys. But do you know how many times they've screwed me over? Not once.

Maybe it's my use cases that make this possible. I definitely modified my behavior to accommodate Linux.

Yes, people like to point out Ariane explosion, without going into the details, and missing out on F-35 budget explosion much worse, with ridiculous failures like having to reboot its avionics in flight.

No, but many of the names are different, and stylistically they are very different. Depending on whether a translation tries to be fairly literal, or sound as if it is written for the language it is translated to the way the result feels will be very different.

An example is the name Bilbo Baggins. In the "canonical" Norwegian translation, he's become Bilbo Lommelun. "Lomme" means pocket, and "lun" means snug, warm, or comfortable. It's not literal, but it fits the nature of hobbits well while referencing the "bag" in Baggins", and the connotations comes immediately in Norwegian without having try to deconstruct the name.

In this case, I think the newer "canonical" translation is generally considered unambiguously the best, but people often have favourite translations. E.g. my favourite Scandinavian translation of Walt Whitman's Leaves of Grass isn't even Norwegian, but an old Danish translation which sounds much "softer" (it's hard to explain)
Show HN: I built a compliance scanner that flags WCAG GDPR and FTC risks in mins
by CraftyGuru | 2026-02-19 11:10:43+00:00
We’ve been building Rataify, a website compliance scanner focused on accessibility (WCAG), privacy regulations (GDPR / CCPA), and FTC marketing claim risks.

Most compliance tools focus only on accessibility and often just wrap Lighthouse or axe-core. Privacy and marketing risk checks are usually manual.

We’re experimenting with a layered approach:

DOM-level accessibility checks (WCAG violations)

Policy presence + structural checks (privacy / terms disclosures)

Heuristic scanning of marketing copy for risky FTC-style claims

Fast report generation intended for pre-launch audits

The goal isn’t legal automation — it’s to reduce obvious compliance gaps before a site goes live.

We’re especially interested in:

False positive tolerance in automated compliance tools

Whether developers would run this as part of CI

What compliance signals are most valuable in practice

Would love technical feedback.

That still leaves you admitting that only a small fraction of the served community can really contribute. You'll need to keep all the best benefits of your work for the Plus users or else there would be no reason to buy Plus and no way to keep paying the few to do all the work for the many.

You're stuck telling people what they can't have (and shouldn't want) while I'm now in a position to just give people what they want. I admire the people who work there, but you need a new business model and fast because I am unequivocally going to collapse your current one.

Used to know someone who worked for a mass production company, outsourcing big clothing orders for UK supermarkets.

It's common for clothing producers (Designers were in the UK in this case, clothes made in china or otherwise) to just pick whoever is in the design office that's about the right size and use them as the basis of all sizing measurements for a given size.

I've even heard of a petite woman being used as the size model for boys 11-12 age supermarket clothes. There's very little thought involved, it's just convenience to be able to tailor the template garment to a real person who's nearby.

I’m unsure exactly in what way you believe it has gone “down the hill” so this isn’t aimed at you specifically but more a general pattern I see.

That pattern is people complaining that a particular model has degraded in quality of its responses over time or that it has been “nerfed” etc.

Although the models may evolve, and the tools calling them may change, I suspect a huge amount of this is simply confirmation bias.
Show HN: Aegis.rs, the first open source Rust-based LLM security proxy
by ParzivalHack | 2026-02-19 11:11:28+00:00
Hey HN,

I've been working on Aegis.rs for a bit, and I wanted to share it. It's the first open-source Rust-based LLM security proxy (that I could find, at least).

I kept having the same issue, since existing LLM security tools are either Python libraries you have to manually integrate into your app, or cloud SaaS products that route your traffic through a third party (which you can't control), and i wanted something that just sat in the middle without touching my code or sending prompts anywhere.

So I built a transparent reverse proxy. You point your requests at localhost:8080 instead of your LLM endpoint and, so far, it catches prompt injections, jailbreaks, PII leakage, and other LLM attacks, blocking them before any malicious request even reaches the model. If a request is clean, it forwards it. If it's malicious, it blocks it. Zero code changes.

It runs two layers: a fast heuristic engine with 150+ hand-crafted (expandable) regex rules that runs in under 1ms (thanks to Actix-web), plus an AI judge using Groq for semantic analysis on ambiguous cases.

Can be easily shipped as a single binary with a live dashboard, hot-reloadable rules, and structured JSON logs.

Still v0.1 but it's working well enough for me to share its first version. The heuristic layer is fast enough for prod, and extending the rules is pretty easy.

Would love feedbacks (or contributions lol), especially from anyone dealing with LLMs' security and threat modeling :)

When I became interested in FPGAs recently, I read this book
https://nostarch.com/gettingstartedwithfpgas

I bought a cheap FPGA board based on Lattice's ice40. There are free OSS tools to write, simulate, and install your Verilog/VHDL design onto the ice40.

It's probably a far cry from what a professional FPGA programmer does with Vivado etc but it might give you an inexpensive idea of the basics and if you want to pursue it.

The thing about a lot of monarchical powers in the UK is that the monarch gets to keep them, provided of course that they only ever use them as prescribed by the government. As to what happens otherwise, well, Charles III won't want to emulate Charles I.

Okay, I was mistaken. The tooling I was speaking of uses Claude Code rather than the SDK. One uses the Zed ACP protocol. I'm not sure about the other. I should have said Claude Code rather than the SDK. For example, I can run a session through one of the tools, and then access that session directly in Claude Code. It's still Claude though. It seems the important element is that you're not using OAuth tokens from a sub to use in a different tool. If you go through Claude Code, then Claude Code is handling everything and giving your tool the output. Thanks for the correction.

Believe me, I've tried. By the time i get the documentation to be the way I want it, I am no longer faster than if i had just written it myself, with a much more annoying process along the way. Models have a place (e.g. for fixing formatting or filling out say sample json returns), but for almost anything actually core content related I still find them lacking.
Show HN: Clipthesis – free, local app to tag and search video across your drives
by hugorut | 2026-02-19 11:14:47+00:00
I'm a hobbyist video creator with a dumb problem: years of footage spread across multiple external drives with names like "C01456". Every time I sit down to edit, I waste too much time hunting for clips I know I shot but can't find.

I tried the usual recommendations (NeoFinder, Lightroom, various DAM tools) but nothing fit how I actually work with video. The online alternatives seemed to charge an arm and a leg, which is hard to justify when you're not running a production studio.

So I built a thing for a free Mac app that indexes all your drives into one searchable video library even when those drives aren't plugged in.
What it actually does

- Index any drive or folder — point it at your external drives and it catalogs every clip with thumbnails, metadata, duration, resolution, etc.
- Tag + search — tag clips however you want (b-roll, drone, interview, whatever), then combine tags to find exactly what you need
- Duplicate detection — content hashing finds the same clip across multiple drives and groups them under one reference. Tag once, applies everywhere.
- Smart import — plug in an SD card and it instantly shows new vs. already-indexed files. One click to import only new stuff.
- Working drive — mark your fast SSD as your editing drive, then one-click copy clips from archive drives when you're ready to cut
- Offline browsing — search, browse thumbnails, and tag clips from disconnected drives. It remembers everything.
- DaVinci Resolve integration — send clips straight to Resolve's media pool with tags as keywords

I built it for myself and I'm putting it out there to see if it helps anyone else. You will probably hit bugs. Actively working on it and genuinely want feedback, what works, what's broken, what's missing.

As far as I remember the original plan was to only maintain both in a transitional phase, with the aim of fully replacing the Java edition. A simple plan: bring Bedrock to feature parity with Java, add a modding API that satisfies 95% of use cases, then force everyone onto Bedrock. The feature parity is mostly there, but modding in Bedrock seems to have become a non-goal, and Bedrock has so many bugs that if your platform offers the choice between both Java is still preferred even if you don't care about modding.

I understood LiFePo4 is pretty safe and innert.

Sodium I saw some reviews where it expands a lot during charging and long term safety is not as conclusive

Why do you see sodium as an easier choice?

The main fire risk with lifepo4 is the connectors, wires, bms and shut off being suitable for high amp. That would be a risk with anything if not built properly, even without batteries if you wire your house with wrong awg wires

More jobless are a burden in a capitalism based social security system.
Has nothing to do if those build something useful or not. Caputalism doesn't care.

In the end the upper 0.1% get the profit and those who still have jobs have to finance the social security systems. More jobless and less working means the jobless become a burden and in the long run the system will fail.

So you either need to tax automation or the rich.
Guess if that will happen.
