checker659··on Rust in the kernel is no longer experimental
OS kernels? Everything from numpy to CUDA to NCCL is using C/C++ (doing all the behind the scene heavy lifting), never mind the classic systems software like web browsers, web servers, networking control plane (the list goes on).
checker659··on I failed to recreate the 1996 Space Jam website with Claude
I think the burden of proof is on the people making the original claim (that LLMs are indeed spitting out original code).
checker659··on Touching the Elephant – TPUs
I've always wondered. If you have fuck you money, wouldn't it be possible to build GPUs to do LLM matmul with 2008 technology. Again, assuming energy costs / cooling costs don't matter.
checker659··on Everyone in Seattle hates AI
> The fundamentals actually haven't changed that much in the last 3 years

Even said fundamentals don't have much in the way to foundations. It's just brute forcing your way using a O(n^3) algorithm using a lot of data and compute.

checker659··on Show HN: A Minimal Monthly Task Planner (printable, offline, no signup)
Great tool. Thank you.
checker659··on The Junior Hiring Crisis
I think the current grads are going to be shafted either way. In 5 years, there might be more opening for "fresh" young grads and the companies will prefer them over the young people who're just graduating.
checker659··on Petition to formally recognize open source work as civic service in Germany
Without open source there would be no code writing LLMs. It is charity of the highest order (to say the least).
checker659··on Google boss says AI investment boom has 'elements of irrationality'
You're right. But I easily round robin between Claude, ChatGPT and Gemini every day without noticing any friction whatsoever.
checker659··on Claude Advanced Tool Use
This is the most creative comment I've read on HN as of late.
checker659··on Show HN: I wrote a minimal memory allocator in C
The structure in the README.md (not the actual structure).
checker659··on Show HN: I wrote a minimal memory allocator in C
That project structure is reminding me of claude.
checker659··on Google boss says AI investment boom has 'elements of irrationality'
But isn't that their "moat"? If the moat is the source of losses, then yes, they're operating at a huge loss.
checker659··on Google boss says AI investment boom has 'elements of irrationality'
Are the companies making a profit on every prompt I give it (factoring in the cost of upgrading GPUs every year or two)?
checker659··on Google boss says AI investment boom has 'elements of irrationality'
The economics of it is what's the problem, not the power of LLMs.
checker659··on Ask HN: What Are You Working On? (Nov 2025)
Ray Kurzweil
checker659··on Ask HN: Is everyone only hiring senior developers? And is it because of AI?
We need to start a company that is like a cooperative that trains juniors to become seniors.
checker659··on Unexpected drug interaction: GLP-1 medications and sedative duration
I think you'd get better answers from GLP1 subreddits and /r/science than from HN readers.
checker659··on Mnist neural network implemented in pure x86 assembly from scratch
> ~7× faster than NumPy

Is that on the CPU (not sure if NumPy has a GPU backend)

checker659··on Show HN: A fast, dependency-free traceroute implementation in pure C
I meant that IFF the author wrote it themself. IFF.
checker659··on Show HN: A fast, dependency-free traceroute implementation in pure C
I was skeptical at first, but this does stink of auto-generated code. I want to believe it is not.
checker659··on Show HN: A fast, dependency-free traceroute implementation in pure C
It could be a vehicle to learn about traceroute / ICMP.

> making it quite unappealing from an engineering standpoint

The other option being rewriting everything under the sun from scratch.

checker659··on Ask HN: Do programmers view memory as pages?
The concept of pages is baked deep into the memory hierarchy (cache, TLBs). What exactly do you mean by precursor? I imagine you're thinking of pages as an abstraction over something more fundamental (?).
checker659··on ChkTag: x86 Memory Safety
I mean, sandboxing AI agents once they get smarter is a valid concern (if not a major future concern).
checker659··on Alibaba Cloud says it cut Nvidia AI GPU use by 82% with new pooling system
They are working with tiny models. Not sure how well it'd scale to bigger models (if at all).
checker659··on Resizeable Bar Support on the Raspberry Pi
Isn't it the DMA engine that's responsible for the data movement? How does the size of the BAR even factor into that?
checker659··on Writing an LLM from scratch, part 22 – training our LLM
> Even when looking at something as barebones as perceptrons

I was thinking something like "it is trying to approximate a non-linear function" (which is what it is in the case of MLPs).

checker659··on Writing an LLM from scratch, part 22 – training our LLM
I have done a little bit of DL stuff (with keras) before this. I'm currently in the attention chapter. The book gives you the code, but I feel like there is very little in the way of building intuition. Thankfully, there are tons of videos online to help with that.

I think it is a great guide. An extended tutorial if you will (at least until this point in my reading). Also having the code right in front of you helps a lot. For example, I was under the impression that embedding vectors were static like in word2vec. Turns out, they are learnable parameters too. I wouldn't have been able to tell for sure if I didn't have the code right in front of me.

So, they were all blind? They couldn't see each other? (Not to mention reflection in water).
