We're in early February 2025 [edit:2026] and the article was written on Dec 23, 2025, which makes it less than two months old. I think it's ok not to include a year in the submission title in that case. I personally understand a y

When I was reviewing such papers, I didn't bother checking that 30+ citations were correctly indexed. I focused on the article itself, and maybe 1 or 2 citations that are important. That's it. For most citations, they are next to

Would those filters be keyword-based only? One benefit of an LLM-based filter I can imagine is that it has a much better understanding of the meaning of text.

Really simple fix: social pressure and expectations should be that every company that uses open source pays a fixed amount of their revenue (is 0.1% low enough to be negligible for the companies). Companies that don't should shunned.

In my dream world, you take that book plus information about yourself (how good of a programmer you already are), feed that into AI and get a customized version that is much better for you. Possibly shorter. Skips boring stuff you know. A

This is interesting if quite incomplete (as noted in the end conclusion). CPU re-order buffers turn what you think as mostly sequential execution into a massively parallel engine. Data memory access, perfecting, speculative execution, etc.

That blog post left me hungry for more. I was expecting Daniel Lemire to provide a SIMD crazy optimized version that shows the default browser implementations are sub-optimal. But it's not in this article. Anyone knows?

To each their own. If you value human interaction, continue to book rides with humans.

That example is too simple for me to grasp it. How would you code a function that iterates over an array to compute its sum. No cheating with a built-in sum function. If you had to code each addition, how would that work? Curious to learn (

Interesting. Is there a picture that explains how the layers talk to each other? Is there a VM system? How does message passing work, what kinds of protections are between tasks? I have had many ideas for such kernels over the years, but no

Instead of just saying: rsync on my system is version 3.2, have you tried copy/pasting rsync --help? In my experience, that would be enough for the AI to figure out what it needs to do and which arguments to use. I don't treat AI

Yes, sounds to me like the user really wanted to sort by time created. And got used to sorting alphabetically as a poor proxy for that.

I don't particularly recommend this article, it's a little bit too simplistic and the reasons given are not quite right.

There never was a problem generating documentation from code That doesn't match my experience at all. Before AI, generating documentation from code was either getting some embedded comments for a function call, or just list a functio

Could it be a TLB issue? Page size on Mac is 4x larger than on Intel.

On modern cpus? Most likely. Those kinds of optimizations are done by the core with no compiler magic needed. CPU implementation has become too complex to grasp. The only sure way to know how a CPU will behave for a given workload is to run

From your blog post: > Random access from the cache is remarkably quick. It's comparable to sequential RAM performance That's actually expected once you think about it, it's a natural consequence of prefetching.

Fair, but it's just a tooling issue. You don't debug your Verilog anymore at the gate-level, do you?

I have fond memories of the IRQ from the mouse card. It was the only source of regular interrupts you could get on the Apple II (that I'm aware of). So in 1987, I tried to write a preemptive switcher, so you could run two code paths at

Remember those startup pivots we used to make fun of on HN? When a pivot happens, it often means the initial idea ran its course, the startup is about to shut down because it's running out of money. However, the team seems to work reas

Appreciate this article that shows some failures on the way to a great result. Too many times, people only show how the polished end-result: look, I trained this AI and it produces these great results. The world dissolving was very interest

The book has great stories. You could skip the job pitch part and jump straight to once she joins Facebook, that's fine too.

[I'm not a lawyer but spent way too much time with intellectual property lawyers] Not true either for a digital book. However, since you are in possession of a digital copy of something that is definitely copyrightable, you have two op

There are several different definitions of unemployment rates: U-3, U-6, etc. Are you sure you are comparing using the same definition? See for instance https://www.investopedia.com/articles/investing/080415/t

Yes, I find the language misleading. Recall to me is synonymous with call-back. Which means I have to bring back , return it. On your PC, when you do a software update, you are not returning your operating system, you are rebooting your PC

I would add one more: the address you are dereferencing could be non-zero, it could be an offset from 0 because the code is accessing a field in a structure or method in a class. That offset can be quite large, so if you see an error access
