What HN said:
tnelsond4: I'm always inspired by SQLite. Overall I like it, but if you're not doing writes it's really overkill. So I made a format that will never surpass SQLite, except that it's extremely lighter and faster and works on zstd compressed files.
xiaod: The operational complexity is worth comparing here. The migration path and schema evolution story often matter more than raw performance numbers for teams choosing between these options.
alexpotato: I have always loved SQLite. I have also heard that some firms ban its use. Why? Because it makes it SO easy to set up a database for your app that you end up with a super critical component of your application that looks exactly like a file. A file that can have any extension.
faangguyindia: I went from thinking “SQLite is a toy product, not reliable for real data" to "lets use SQLite for almost everything" SQLite is very good if you can fit into the single writer, multiple readers pattern; you'll never lose data if you use the correct settings, which takes a minute...

The event's Leave No Trace principle isn't just a promise — it's measured, mapped, and made public.
What HN said:
stonegray: I’ve done this for a couple years now, cool to see it pop up here. I believe the scale is a touch larger; 3935 acres in 2025, plus a small amount outside the fence line. On the technical side, we not only log but photograph everything, down to each clump of toilet paper.
ruleryak: Last year was tough - it rained for hours 5 nights in a row and the first rain night was accompanied by 70 mile an hour winds that did a massive amount of damage to camp infrastructure throughout the city.
childofhedgehog: So a giant party can clean up after itself, but 4th of July in Tahoe for example is a toxic mess. I wish more people would practice these principles. It’s impressive how well this is cleaned up.
justin: What I love about Burning Man is that it is an event where all the programming is created by the attendees. All the art, sound stages, art cars, experiences.. if you want something to exist in Black Rock City, then it is up to you to just go figure out how to bring it, solely for...

What HN said:
CrzyLngPwd: It seems to me that adding AI to desktop apps and sending the data back to the mothership for processing is an amazing way to collect data from people who, for the most part, would be completely unaware it's even happening. Heck, most of them think the Internet is Chrome.
cferry: My belief is that the AI business is all about data collection. The value isn't so much in the quality of the models (that's what enterprise customers and developers pay to get), but in the amount of data that comes "for free" to whoever hosts the models.
avdelazeri: And right after https://news.ycombinator.com/item?id=48019219 huh
SunshineTheCat: I know that I'm in a bit of a bubble with this one, but I am surprised there is still anyone using Chrome instead of Brave. I get the dependency on Gmail other Google-specific tools, but the built-in ad blocking and Google-free aspects of it made me switch instantly and haven't l...

A locally tailored, big-push intervention to educate unmarried adolescent girls in 18 communities in northern Nigeria reduced rates of marriage from 86% to just 21%. Interventions that address complex, entrenched social problems from various angles simultaneously might be conside...
What HN said:
eckesicle: I run a company that have done over 200 similar studies for various NGOs and international organisations. In the general case, with some exceptions, we have found that two types of interventions stand above all others in terms of long term positive economic impact: 1.
nerdjon: Reading this, I can't help but feel like there is a weird correlation here going on. It seems less specifically about the school and more about the support system and the safe place that this program gave to the girls.
tolerance: Are people just riffing off the headline, the subheading and the first sentence of this page, is the full paper open access, or has anyone read the more substantial policy brief associated with the study [0]? That's not to say that there's nothing of value being discussed here wi...
mzi: This kind of data was shown by late Hans Rosling and his foundation Gapminder¹. He gave a Ted talk² about similar subjects as well, and I find him an excellent lecturer. ¹ https://www.gapminder.org/ ² https://www.youtube.com/watch?v=hVimVzgtD6w

What HN said:
momojo: This reminds me of Antirez's "Don't fall into the anti-AI hype" [0] In a sentence: These foundation models are really good at optimizing these extremely high level, extremely well defined problem spaces (ie multiply matrices faster). In Antirez's case, it's "make Redis faster".
pingou: AI improving itself (or at least the architecture it runs on), the singularity is near as they say. Do we have other examples of AI being used to improve the LLMs, apart for the creation of synthetic data and the testing of the models?
alecco: Are Googlers themselves happy using Gemini coding agent instead of Claude Code or Codex? (no snark, I'm really asking)
dandaka: How many times we have to hear again about Erdös problems? :) It sounds like a great achievement for humanity at first, but after a while they keep coming back!

Fewer people are buying parts and building new PCs from scratch.
What HN said:
hx8: PC is the last major open platform. While other platforms like Android and becoming less open, PC in general is becoming more open than it's been in a long time as heavy MacOS/Android/iOS competition is creating a focus on open standards and all-time high strong Linux support gi...
post_break: Motherboards used to be $100, $200 for the high end. Now they want $300+, ram is crazy, storage, video cards, etc. I'm not surprised sales for these components is hitting a wall.
quantified: When photosynthesis first appeared, the oxygen it produced poisoned the existing life. Sulfur-breathers basically disappeared. In the geologic record the oxygen shows up as massive layers of iron oxide which we mine and turn into steel now.
Kirby64: Not just motherboards. Cases, PC accessories (fans, etc), consumer SSDs, and more. Cases are especially hard hit, apparently, as they're already quite a low margin business. Personally, I see little reason to upgrade from my AM4 platform.

DeepSeek 4 Flash local inference engine for Metal. Contribute to antirez/ds4 development by creating an account on GitHub.
What HN said:
kgeist: Heh, I made something very similar for the Qwen3 models a while back. It only runs Qwen3, supports only some quants, loads from GGUF, and has inference optimized by Claude (in a loop). The whole thing is compact (just a couple of files) and easy to reason about.
antirez: A random, funny, interesting and telling data point: my MacBook M3 Max while DS4 is generating tokens at full speed peaks 50W of energy usage...
maherbeg: This is so sick. I'm really curious to see what focused effort on optimizing a single open source model can look like over many months. Not only on the inference serving side, but also on the harness optimization side and building custom workflows to narrow the gap between things...
amunozo: I am curious about it producing less tokens except for the max mode. I love DeepSeek V4 Flash and I use it extensively, it's so cheap I can use it all day and still not use all my 10$ OpenCode Go subscription.

What HN said:
sneilan1: I did not realize Boris made the tutorial that got me into programming. Wow. What a great find! And is the Ilya S Ilya Sutskever?
z_open: It's funny how many software developers got into it due to being bored in class with a TI-83 and randomly trying to create programs.
sp1nningaway: This made me wonder about Boris Cherny's professional career pre-Claude Code, so I did a customary "Boris Cherny wiki" Google. I'm shocked to learn he doesn't have a Wikipedia page! Is this my Hacker News bias? He's a ubiquitous online topic and has had an outsized impact on the...
vvoyer: For anyone wondering, Boris Cherny created Claude Code.

Thesis: reliable agents tackling complex tasks need deterministic control flow encoded in software, not increasingly elaborate prompt chains If you’ve eve...
What HN said:
rnxrx: I wonder if a part of the problem isn't just the misapplication of LLMs in the first place. As has been mentioned elsewhere, perhaps the agent's prompt should be to write code to accomplish as much of the task in as repeatable/verifiable/deterministic a way as possible.
bwestergard: I agree with the sentiment, but I think the conclusion should be altered. When you hit the limit of prompting, you need to move from using LLMs at run time to accomplish a task to using LLMs to write software to accomplish the task.
jerf: This is why I frequently refer to "next generation AIs" that aren't just LLMs. LLMs are pretty cool and I expect that even if we see no further foundational advancement in AIs that we're going to continue to see them exploited in more interesting ways and optimized better.
sudosteph: This is a good discussion topic. A lot of people really seem to believe that if you word a prompt just so, that you just need to throw a high-powered model at it, it will work consistently how you want. And maybe as models progress that might be the case.

Rust TeX-style math layout with KaTeX-aligned golden tests. Ready-to-use packages for Web (WASM), iOS, Android, Flutter, and React Native—same display list everywhere.
What HN said:
Hendrikto: I used LaTeX for approximately 10 years, for little things to relatively complex, including my bachelor’s and master’s theses. It never felt natural at reliable or consistent. Every customization required weird \makeatletter \makeatother hacks and was very brittle.
tabbott: It's interesting to me that the page doesn't describe the size of the rust binary (relevant for mobile app use cases where you would need to add the Rust binary to your app) or performance.
azverev: Pixel-diff CI against a golden suite is the right discipline for layout libraries, and it's noticeably rare in the JS ecosystem. Most "matches KaTeX" claims I've seen in the wild rely on screenshot eyeballing, which collapses on edge cases like spacing primes, integral subscript...
xworld21: I suppose somebody has to ask (and most likely complain) about this: what does RaTeX do for accessibility? I gather that it produces images. I checked the demo, and there's not even an alternative text or an ARIA label, so this seems completely invisible to anybody relying on a s...
