this is sad. i feel for her. i went through this in august, still haven't gotten an offer yet.
The worst part to me is their inability to tell the truth because of what seems to be legal reasons?
This makes them one of the largest car companies in the world. Pretty wild
apstats commented on Ask HN: Why is there no such thing as "open source marketing" · Posted by u/presspot
I think the equivalent is basically blog posts. It’s hard to formalize marketing in the same way CS things can be formalized.

I wonder if this could be used to train an LLM to convert PDFs with rich charts into HTML?

I only used Bird once and have always thought they were not a great way of getting around. That said this is a real bummer to me. If commuting and mobility were much much easier the world would look a lot different for the better (in my opinion).
I hope there are more attempts to make getting around and getting to places you need and want to go easier.
apstats commented on Ruby 3.3's YJIT: Faster While Using Less Memory railsatscale.com/2023-12-... · Posted by u/ksec
I benchmarked a good sized app (ran a black-box QA suite multiple times) while monitoring performance and req/response times with Prometheus/Grafana with Ruby 3.2.
With YJIT enabled memory usage ballooned and performance dipped below non-YJIT Ruby 3.2, IIRC the difference was a good 10% degradation. Granted, it's an API only service so no HTML is being generated, only JSON and that could be the culprit.
Suffice it to say, we didn't enable YJIT for 3.2. Maybe 3.3 is indeed different, but both the faster and less memory claims are really suspicious to me.
Interesting. Do you think html generation is one of the things that makes the numbers look so good for 3.2 YJIT? We run a mostly json api only app. I think json serialization is notoriously slow in ruby so I was hoping yjit would speed it up.

Yeah, our last benchmark was with 3.1.2 + YJIT, but we actually saw a regression in term of performance while RAM usage was indeed up: https://serpapi.com/blog/benchmarking-ruby-3-1-yjit-ruby-2-7...
Very interesting blog post! My best guess as to how shopify is able to achieve such large increases in speed is they have a lot more actual ruby code than most codebases (https://shopify.engineering/ruby-yjit-is-production-ready).

I moved from ruby 2.7 to 3.2 for a rails app and was hopeful that it would lead to large speedups like shopify claims it did for them, but was bummed to find it did basically nothing. Anyone else running a large rails app have a similar or different experience?
