Continuing only makes sense for cases you know you can handle. _In theory_ they could have used the old config, but maybe there are reasons that’s not possible in Cloudflare’s setup. Whether or not that’s an invariant violation or just an e

People think management sucks at hiring good talent (which is sometimes true, but I have worked with some truly incredible people), but one of the most consistent and costly mistakes I’ve observed over my career has been management's p

Same! I feel like I'm on crazy pills. Multiple folks in this thread are saying stuff like, "yeah, Rust, cool, but it has zero use". How are Linux, Microsoft, AWS, Cloudflare, Firefox, Python's `cryptography`, etc., not r

Thank you for this post and I'll add a note for people who are seeing this and are maybe discouraged about learning Erlang/OTP/Elixir. I generally agree with you that learning Erlang stuff can be daunting. I will say that man

Same! I had a job at a shop with a monolithic Rails app where I had so much trouble understanding the codebase I almost quit the industry entirely. Maybe I am just stupid when it comes to reading Ruby/Rails or maybe that codebase was u

There are quite a few Elixir shops that are willing to hire people who don't have a ton of experience with Elixir but have experience building and understanding systems generally. So my advice is, try to bolster your story that you can

Maybe for you! That's your call. I'm also interested in my career. I've had 3 Elixir jobs and 2 Rust jobs in the last 10 years. All were on real products, not vaporware. I learned a ton , worked with great people, and made r

You tell your editor to evaluate any arbitrary part of the source file you currently have open, and it does so in the context of your running application without stopping it. Then you see the result in another pane of your editor. It's

Folks, if you have problems doing async work, and most of your intense logic/algorithms is a network hop away (LLMs, etc.), do yourself a favor and write a spike in Elixir. Just give it a shot. The whole environment is built for async

As someone who has gone deep into both functional programming (with Elixir, Clojure, and Scala) and also Rust, they solve the same problem in different ways with different tradeoffs. The problem is that shared mutable state is incredibly h

It’s a reasonable question! In WAL mode, writers and readers don’t interfere with each other, so you can still do pure read queries in parallel. Only one writer is allowed at a time no matter what, so writers queue up and you have to take t

SQLite is a truly remarkable piece of software that is a victim both of its own success and its unwavering commitment to backward compatibility. It has its quirks. There are definitely things we can learn from it.

In SQLite, transactions by default start in “deferred” mode. This means they do not take a write lock until they attempt to perform a write. You get SQLITE_BUSY when transaction #1 starts in read mode, transaction #2 starts in write mode, a

Agreed. If you can find one. I bought a new vehicle in 2023 after years of not owning a car. I was trying to buy used, but the delta between new and 1-3 year old used was so small it made no sense to go used. I was giving up a warranty for

OTP typically handles this with timeouts and then restarts when timeouts occur. Not to say it can't happen, but there are strategies.
