A few days ago, I received a license for Rust Rover from my company, and today I received permission to use it after hours for my personal projects. So it looks like I'll drop VSCode for a while (but not Helix 🤣). What I'm really happy about is the database schema compare tool.

Cautionary story for all who want to rewrite old tools. www.phoronix.com/news/Ubuntu-.... It's better to create new tools and not have to think about backward compatibility. All drop in replacements are prone to such problems and need to take extra care about compatibility.

It's just data from Google AI, I'm not sure if it's true. In my experience, a small Dioxus app runs with just around 4 MB of RAM when I run development version with dx serve. IMO it's a huge business opportunity in replacing all this Electron-based, memory-hungry slop.

"Premature optimization is the root of all evil".
Before you start optimizing you need to really know what you are trying to do and how current implementation works. Something may look not 100% optimal, but it looks that way because there is a good reason for that.

Today I've spent a few hours working on a side project - a simple numbers related game. I'm using Dioxus and Tailwind. I can't say it's trivial, but it's quite easy. It's really worth a try if you want a cross-platform solution for Windows, Linux, Mac, Android, iOS, and web.

I'm not sure if I should go down this rabbit hole - ./x.py bench --stage 1 compiler - I created some benchmarks for SmallVec vs Vec, and I'm starting to doubt in the sense of using SmallVec. Seriously, you should use SmallVec only when you benchmark and prove that it's better.

Last Friday I was in a rollercoaster park, because my son had his 10th birthday, so maybe I missed the noise and ovations. Today I had a nice 9,5 hours of work with Rust 1.90.0 compiler, and I must say that LLD is a game changer in terms of build process speed.

I've been using nightly for almost 6 months to use LLD for tests, because it has increased the speed of the whole testing process for me a lot. In Rust 1.90.0, I'm also using it for normal project development. And it speeds up things for me a lot. Finally! 😀

I wonder if dividing a proprietary project into multiple crates isn't an anti-pattern. You have like 320k LOC in 70 crates. Sometimes it's hard to refactor due to circular dependencies. Not to mention the orphan rule. It's not impossible to have that code in subdirs in one crate.

If a function returns Option or Result, it's a good practice to start its name with the try_ prefix. If a function returns a mutable reference, it's a good practice to end its name with the _mut suffix.
