BiraIgnacioon Citadel Buys Situational Awareness's Stock Portfolio After Big Losses in AI

I didn't know buying other funds stock portfolio was even a thing. TIL

I guess it makes sense, wondering what Citadel will do with it...

BiraIgnacioon Why is everyone trying to build a solid-state battery?

> The flavour you want is polymer, single ion conducting solid state with an ion transport activation energy below 10kJ/mol at room temperature and no phase transitions from -40C to 80C.

what makes it so? I don't know anything about this subject, I'm really curious now about what the perfect battery would be.

BiraIgnacioon Pizza, pasta, potatoes, protein – how Italian children became so overweight

So the problem is not Pizza nor pasta nor potatoes nor bread nor protein but all the extra supper high calories, near zero nutrition things that go on top of them?

The best suggestion, thank you

BiraIgnacioon OpenAI’s accidental attack against Hugging Face is science fiction that happened

Call me obtuse but the way this is being portrayed by the companies involved, media, seems a little odd to me.

Didn't the model + harness do what was asked? If I ask a coding agent to write a very clever piece of code and it turns out impressively clever, it did what I asked.

BiraIgnacioon The startup's Postgres survival guide

I'd say this applies to any database management system.

BiraIgnacioon Are we offloading too much of our thinking to AI?

Humans have been offloading thinking to something/some entity forever. From gods to influencers.

AI is the current popular way (at least in these circles) and if it's too much or too little it might not matter. What will matter is if this offloading is making people unhappy and having any negative impact in civilization. I have no idea

BiraIgnacioon The Underhanded C Contest

> The contest was initially inspired by Daniel Horn’s Obfuscated V contest in the fall of 2004 (note: the original page is long gone, and this link goes to a snapshot from archive.org). The object of that contest was to write a simple program to count votes, that somehow miscounts the votes on election day. I was greatly impressed to see how even a short program to simply count characters in a text file can be made to fail, and fail only on one specific day, so that the bug isn't noticed in testing.

Definitely a lot.. thanks, missed that

Is this a little or a lot? any idea how that compares to other industries and donors?

BiraIgnacioon The MUMPS 76 Primer – anniversary edition

I remember when I got into programming, when the thing to use was basic on a TRS-80, a friend was showing me how MUMPS was as much better language than basic.

Good times

BiraIgnacioon The anxiety of the perfect loaf: the illusion of culinary precision

I eat a lot of bread and I make a lot of bread because of that.

Precision measure and mixing and timing helped me a lot in the beginning.

Though I still do that, I find that now I can rely on feel (experience if I'm honest) to know when the dough is just right.

Like with everything, there's probably a middle ground there but I think I just like having fun pretending I'm on a chem lab :)

BiraIgnacioon We built a persistent agent memory layer on Elasticsearch with 0.89 recall

TIL

- Hybrid recall + reranker: Two searches merged, then re-scored for best matches

- Supersession: Old facts get hidden, new ones take their place

- Decay: Recent or often‑used memories get a score boost

- DLS: Each user only sees their own documents

BiraIgnacioon Ask HN: Has anyone replaced Claude/GPT with a local model for daily coding?

I tried for a bit, with llama.cpp + Qwen + Mac Pro but the results were very poor (both quality and speed).

I considered investing in better hardware but doing the math, it is cheaper for me to pay for DeepSeek (yeah, I know not everyone can do that).

Holly bananas, that Boost Design Rationale post is, what's the word I'm looking for, intense.

BiraIgnacioon My Software North Star

> I have worked in companies where "X is not complete" would be logged as a bug

I've come to realize it's all about perspective. Something from the engineering stand point may not be a bug because there's nothing to fix. But the user might be having a bad experience because of that so it must be a bug.

In the end, the user's perspective might be the less-wrong one.

BiraIgnacioon Gemma 4 12B: A unified, encoder-free multimodal model

using an embedder instead of a decoder is quite clever. Not sure who came up with that first but it's a cool idea.

BiraIgnacioon Real-time LLM Inference on Standard GPUs: 3k tokens/s per request

I know all is relative but when I think of > 8× AMD MI300X GPUs and 2,100 on 8× NVIDIA H200

I still find it mind boggling. That's a lot of compute power and still considered "low end" for the purpose it serves.

BiraIgnacioon DuckDuckGo search saw 28% more visits after Google said people love AI mode

Well, if the marketing teams are being told to reach people using AI or something like that, then Google is just playing to their real customers.

Just cause that level seems to be working fine for me and it's usually faster.

As for out tokens, it's about 200k/day

BiraIgnacioon DeepSeek makes the V4 Pro price discount permanent

I've been using V4 flash consistently with Claude. Pretty great fast and darn cheap. I use it about 3h/day and so far haven't crossed $1 USD/week.
