To be clear, the fastest theoretically possible C++ is probably faster than the fastest theoretically possible Julia. But the fastest C++ that Senior Data Engineer candidates would write in ~2 hours was slower than the fastest Julia (though

> Python is sometimes slower (hot loops), but for that you have Numba This is a huge understatement. At the hedge fund I work at, I learned Julia by porting a heavily optimized Python pipeline. Hundreds of hours had gone into the Python

I'm pretty enthusiastic about LLMs and use them on my 8 year old codebase with ~500kloc. I work at a hedge fund and can trace most of my work to dollars.

For what it's worth, I've been using a fairly minimal setup (24 lines of CLAUDE.md, no MCPs, skills, or custom slash commands) since 3.7 and I've only noticed Claude Code getting significantly better on each model release.

Mine is 24 lines long. It has a handful of stuff, but does refer to other MD files for more specifics when needed (like an early version of skills.) This is the meat of it: ## Code Style (See JULIA_STYLE.md for details) - Always use e

Maybe you just don't read many books written after the year 2000? It was a pretty common word even before ChatGPT: https://books.google.com/ngrams/graph?content=delve&year_sta... But perhaps the most famous so

It's doable if you pick a very focused topic. In my first year of using Julia, I gave a talk on gradually adding Julia to a large Python codebase. Very few people could give a similar talk because (1) Julia is a fairly niche language,

You can still use git worktrees in a colocated repository. jj workspaces are a different, but similar capability that provide some extra features, at the cost of some others.

"When is jj useful" is a different question from "when are workspaces/git worktrees useful" I find jj overall most useful for separating the concept of a machine-level commit history that saves every change from a h

I'm in a similar position, I want to learn both eventually but chose to start with Rust because it has several really strong-seeming (like the intro book, or Rust Atomics and Locks), while Zig doesn't have many books yet.

If it's been around for a while, look at the last year's worth of projects and estimate the total delay caused by the specific piece of tech debt. Go through old Jira tickets etc. and figure out which ones were affected. You don&#

I usually run one agent at a time in an interactive, pair-programming way. Occasionally (like once a week) I have some task where it makes sense to have one agent run for a long time. Then I'll create a separate jj workspace (equivalen

My wife is deaf, and we had one kid in 2023 and twins in 2025. There's been a noticeable improvement baby cry detection! In 2023, the best we could find was a specialized device that cost over $1,000 and has all sorts of flakiness&#x2F

There are a lot of programming language journals – are there ones you'd recommend specifically for discussions of tradeoffs between features?

Not quite the same, but I find "data-oriented programming" to be a very strong method for managing large codebases. By that I mean having data structures that designate the end state that you want, having another set of code that

I would be interested in serious attempts to argue for this, even if they can't reasonably be backed up by data. For example, I think there's a pretty strong argument that immutability makes it easier to write multithreaded code (

I didn't mean the application is less performant (indeed, it might be even more performant since there are more things we can tweak), but that the overall build + upload process is noticeably slower. I remember it taking <1 minute t

Do you know of any articles/papers that try to do in-depth analyses of which features are helpful for building big systems? Most posts I can think of basically say "X language is good" or "Y language is bad", but I&

Re 1: I like Matt Ranney's take on it, where he says microservices are a form of technical debt – they let you deploy faster and more independently in exchange for an overall more complex codebase. This makes it clear when you might wa

I loved uberjars back when I was writing Scala. I don't miss much about the JVM, but I really miss having a single executable I could just upload and run without having to pay attention to the environment on the host machine.

In addition to other answers, one way to think about it is that the options are symmetric around the midpoint: a guess that partitions the space into (1/4 of options, 3/4 of options) is the same as one that does (3/4, 1/

Do non-software projects succeed at a higher rate in any industry? I get the impression that projects everywhere go over time, over budget, and frequently get canceled.

A lot of interesting math can't be done in numpy, sadly. At that point you might be better off writing the initial version in Python and translating it to something else. A friend of mine asked me to translate some (well-written) numbe

I've found Julia to work quite well for this if you're focused on data/numeric code, though admittedly that's a bit of a niche.
