I think it’s hard to truly appreciate any sport you haven’t played yourself. I personally cannot get excited about baseball, and it’s probably mostly because of my own lack of playing experience.

New comment by jrpelkonen in "My Thoughts on Bun's Rust Rewrite"

jrpelkonen — Sat, 16 May 2026 17:14:57 +0000

I agree with most points, but I believe the main reason behind TigerBeetle’s lack of memory errors is that they follow the power of 10 rules and do not manage memory dynamically beyond initialization. Team culture and aligning with Zig philosophy are far behind in importance.

New comment by jrpelkonen in "Rewrite Bun in Rust has been merged"

jrpelkonen — Thu, 14 May 2026 18:48:12 +0000

While I don’t have personal experience with either project, I feel it is safe to say that Bun and TigerBeetle are not comparable projects: TigerBeetle has a strong focus on testing and correctness, and Bun maybe not so much. IIRC, TB did well in the Jepsen test and had one segfault in a client library. Bun has had quite a few memory safety issues, in fact, the stated motivation for the Rust move is to eliminate those going forward. We shall see how that pans out.

Your point is completely invalidated by useless name calling. The people behind cargo are clearly accomplished and serious individuals, and even if you disagree with some of the choices, calling them bozos makes your whole argument unconvincing.

Somewhat related: Jiff (https://github.com/BurntSushi/jiff) is a Rust library inspired by the Temporal api.

New comment by jrpelkonen in "Finding and fixing Ghostty's largest memory leak"

jrpelkonen — Sat, 10 Jan 2026 22:30:50 +0000

Great write-up. And, thanks mitchellh for Ghostty, I switched to it last year, and have not regretted it.

However, I am a somewhat surprised that the fix is reserved for a feature release in a couple of months. I would have expected this to be included in a bug fix release.

SSH was around, but not nearly as pervasive it is today. I have memories of having to shake my mouse around during the windows client installation to generate entropy. Fun times

The typestate pattern common in Rust applications allows the compiler to verify that the operations are executed in the right order and that previous states are not accidentally referenced. Here’s a good description: https://cliffle.com/blog/rust-typestate/

There is, in fact, a spec to read[1], as of earlier this year.

New comment by jrpelkonen in "Automatically Translating C to Rust"

jrpelkonen — Sun, 02 Nov 2025 14:29:09 +0000

Fil-C is an innovative approach and a great technical achievement. However, I wouldn't suggest that it is an universal solution without caveats. For instance, the performance penalty of up to 4x is not acceptable in a lot of cases.

Also, the c2rust output is rough but not hopeless: There are real world success stories of rust projects that were bootstrapped via c2rust, e.g. https://tweedegolf.nl/en/blog/151/translating-bzip2-with-c2r...

New comment by jrpelkonen in "Unpacking Cloudflare Workers CPU Performance Benchmarks"

I appreciate the candor, and I agree that auto-adaptation probably makes sense in this use case because the workloads are unknown and varied.

New comment by jrpelkonen in "Unpacking Cloudflare Workers CPU Performance Benchmarks"

jrpelkonen — Wed, 15 Oct 2025 11:46:20 +0000

Great write up, focusing on facts without fingerpointing.

But I must admit I was somewhat surprised Cloudflare was not already proactively monitoring and tuning the generation sizes. Configuring the generation sizes was table stakes for JVM performance tuning back in the day.
