That's helpful context, thanks. Unfortunately I cannot edit my original comment, but good to know.

Never forget https://news.ycombinator.com/item?id=8863 > 1. For a Linux user, you can already build such a system yourself quite trivially by getting an FTP account, mounting it locally with curlftpfs, and then using SVN

It's a problem with a long tail, and it very much depends on what objective you're optimizing for. In search at least, you aim for "good" and "better", but will never achieve "perfect". It's a pr

Different incentives. A publically traded corporation with thousands of workers trying to grow in perpetuity, has different goals than a community project. While the former has more resources, the latter is more mission driven.

if you have a task that is easy to split, make a python script that runs on a subset of the task, split into N subsets, and write one output per process? Once they all complete, join together the outputs. Maybe https://docs.dask.

The software support just isn't there. The drivers need work, the whole ecosystem is built on CUDA not OpenCL, etc. Not to say someone that tries super hard can't do it, e.g. https://github.com/DTolm/VkFFT .

What's even better is that net zero isn't doing anything for _already emitted carbon_, or the already accumulated heat energy. We can get to net zero and average temperature is still going to keep rising.

These vectors are lower-dimensional than traditional vectors though, aren't they? Vector embeddings are in the hundreds to low thousands range of dimensions (roughly between 128-1024), whereas TF-IDF has the same dimension as your voca

User/Item/Query embeddings are the most common. That way you can generate per-user recommendations, or search results for a given query (with personalization using side information). Video will be interesting, once we have video e

IMO there are many Americans who would work in IT/Tech if you paid them to do it, but the risk calculation doesn't currently make sense. If you're an adult making $25-35/hour in your current job, just meeting rent/u

Perhaps more precisely: the defacto Apache-as-runtime + PHP model simplifies a ton of things. Namely your request state is created and destroyed all within the context of a single process, and you don't have to reason about shared stat

PHP has some excellent ideas that other languages can't replicate, while at the same time having terrible ideas that other languages don't have to think about. Overall a huge fan of modern PHP, thanks for this writeup.

Yes, things are worked out pretty well, in the end it didn't take long to find _something_ as a dev, but I think early next year should be a good time to apply to "good" companies. In-network people are telling me things are

Get a few RPis and get https://k3s.io/ running on them. Get familiar with kubectl. Deploy a few apps to your cluster, tail some logs, restart containers, scale them, etc. Install Prometheus, get monitoring working, make som

if you apply to roles within finance you'll have a better shot of landing something. Also, do a quick project using k3s and / or docker to get the basics, so it sounds like you know what you're doing. You can be creative with

You'll need to send much more than 12, try 2-3 a day for a month. Of those, maybe 5% will reply, but it's not bad that bad once you get into the swing of it.

Yeah I've noticed we've done an about-face on degrees in industry. It used to be super legit to drop out. As things get more specialized MS and PhD are seen more favorably now.

Referrals are also not a golden ticket right now. Got a few tossed in the bin, we've got a lot of FAANG engineers on the market right now, companies are scooping them up at bargain rates.

I was in this boat a few months ago, doing a lot of exercises on leetcode legitimately helps, because you can quickly type an ~80-90% solution immediately from memory, and you have a lot of time left over to finish the remaining portion. It

RE point 1: in the actual job these days, we're coding through so many layers of distributed madness that you end up doing YAML/JSON engineering and gluing systems together more than anything, for years on end. A lot of "so

That was on GPU, and there are various CPU implementations (e.g. based on Tencent/ncnn) on github that have similar runtime (1-3s / iteration).

Yeah for comparison, `tinygrad` takes a little over a second per iteration on my machine. https://github.com/tinygrad/tinygrad/blob/master/examples/st...

The above project somewhat supports GPUs if you pass the correct GGML compile flags to it. `GGML_CUBLAS` for example is supported when compiling. You get a decent speedup relative to pure C/C++.

Rust's binary search used to be branchless but due to some issues down in LLVM land, the codegen doesn't issue a `cmov` where it should. https://github.com/rust-lang/rust/issues/53823 old branchless

For extremely low latency, Clojure can be an awkward fit. By default there's a lot of sugar in the syntax, so if you need to be precise about the underlying types of your data and the exact datastructure, you need to toss out most of t

Thanks a ton Rich, Clojure is a real breath of fresh air in programming languages. I hope it continues to influence progamming for years to come, looking forward to seeing what you come up with in the future!

Sorry to revive an old thread, but I just wanted to add that I did not interview with any FAANGs. All were either startups or at most mid-tier companies. I think the well-funded startups do copy FAANG style interviewing.

Thank you for this anecdote. This is where I am currently at, but I don't feel discouraged at all, I feel up to the challenge! I am finding the process of learning fun and I am in fact improving a ton at the fundamentals. My speed is i

If you view the list here: https://leetcode.com/problemset/all/ you will see the questions tagged by company (there is a paid option as well). If they have a name you know, they probably do this style of interview
