#materialism is an illusion. "To remain intellectually honest, not just with ourselves, but with the universe at large, we must accept that materialism is a mere illusion, a projection of the mind." https://philosophyofbalance.com/blog/materialism-is-an-illusion/ Reply to this toot to have […]

Free Will is real and you better believe it! That's a bold statement, I know, and one that I cannot prove. Yet I do believe it is our most rational position to take. Read on: https://philosophyofbalance.com/blog/free-will-you-better-believe-it/ #philosophy #philosophyofbalance #freewill

Hot take: #Microsoft should’ve had the balls to just revive #clippy instead of introducing #MiCo. Now everyone’s laughing that it’s Clippy 2.0 anyway, but if MS had been the ones calling it Clippy, they would’ve been able to preempt the fun making. And they could’ve spinned it by saying the […]

For the past few months I’ve been working on a new project, quite unlike any I did before. In an attempt to heal polarisation, to make people believe again, and to educate, I’ve embarked on a mission to create the #philosophy of Balance. I’m writing a book on the topic, but for now I wish to […]

Shower thought: `Cow` should really be named `Boo`. Rust's `Cow` type was created for Copy-on-Write (CoW) use-cases, but more and more I find myself using it for random situations where I need a value that is either borrowed or owned. Boo. #Rust/#Rustlang

With this latest PR, inference for `noFloatingPromises` is pushed to over 80% success rate in Vercel's repositories: https://github.com/biomejs/biome/pull/6404 While I targeted specific patterns used by their own `swr` library, all the fixes are generically applicable, meaning other code […]

With Biome v2 reaching ~75% accuracy for the `noFloatingPromises` rule, one might wonder, how? * First of all keep in mind this is measured on a single (very large) repository. Yours might fare differently depending on libraries/patterns/etc.. * What you're seeing is a successful application of […]

My Vercel contract is almost coming to an end, but I'm extremely happy that we managed to get to about 75% success rate for `noFloatingPromises` in our v2 release: https://biomejs.dev/blog/biome-v2/ The success rate is even slightly higher already in the `next` branch, and I still have 2 weeks […]

Over the weekend, I wrote an overview of Biome's type architecture, including our motivation and a discussion of the constraints that led to this architecture: https://arendjr.nl/blog/2025/05/biome-type-architecture/ Reply to this post to comment! #OpenSource #WebDev #tooling #JavaScript […]

Looks like your migration went well 😉

I'm now two weeks in on my work on @biomejs 's type inference and we can now resolve types in this code: ```ts class DeepThought { /* class members */ } export const superComputer = new DeepThought(); ``` It doesn't matter that `DeepThought` isn't being exported, or that the code is defined […]

Upgraded my #Email from GMail to the Dutch-based StartMail. I like that I can use a single account for my 3 domains at no extra cost. Just be aware that it doesn’t offer calendar or contact sync, but given I have an iPhone too, I could easily move those to iCloud.

I've just published a blog post that I'm looking for new challenges. Give it a read, click around to my blog for a while, and see what I might be able to do for you! https://blog.startifact.com/posts/new-challenges-2025/ #rustlang #getfedihired

🔥 eval-macro - lets you write inline Rust code that gets evaluated at compile time to generate Rust code - Combines the power of procedural macros with the ease of `macro_rules!` Crate: docs.rs/eval-macro/l... Discussion: www.reddit.com/r/rust/s/Wsa... #rustlang

I’m feeling like a true rebel today. Removed all my #US English keyboard/autocorrect settings and changed them to British.

Het is heel moeilijk te accepteren, maar we moeten ophouden onszelf te foppen met rare juridische argumenten, technische trucs & "hoop". Amerika & hun clouds zijn geen veilige plek meer meer om onze maatschappij en overheid op te laten draaien […]

Recent events in #Politics triggered me to write a manifesto on the values of #Democracy and what we can to do preserve them: https://arendjr.nl/blog/2025/02/new-monarchy/ Reply to this post to comment.

Another exciting #biome development: I just opened a PR for our first **multi-file analysis rule: `noImportCycles`** There is still some other tasks I need to do to complete the multi-file analysis, but hopefully this means we've also reached the point where contributors can chime in and […]

After watching #blackdoves , I can’t help but wonder how many women get falsely accused of cheating by their partners, while really, they are just spies instead 🤔

Nice post about #Rust auto-vectorization by Evan Schwarz: https://emschwartz.me/unnecessary-optimization-in-rust-hamming-distances-simd-and-auto-vectorization/

This Thursday, I gave a presentation about @biomejs at the @jetbrains office in #Amsterdam. It was great to hear all the positive feedback about our project, and anecdotes from both users and people who may become our users 😊 It was nice talking to you, and […] [Original post on mstdn.social]

If you have no plans yet for Thursday night and you happen to be around #Amsterdam, I'll be speaking about @biomejs at the #Rust #meetup at the @jetbrains office: https://www.meetup.com/nl-NL/rust-amsterdam-group/events/304514267/ Maybe I'll see you there!

If anyone ever wonders where I find the time to work on @biomejs: I’m doing #freelance work 32 hours a week. #biome is my “20% project” ☺️ #OpenSource #portfolio

Lately I've been brooding on how best to implement Multi-File Analysis in @biomejs. So I've collected my thoughts and written them down in an RFC, so our community can understand our choices and see what we are working on. Read all about it here […]

Next time someone says #Rust has long compile times I’m referring them to #swift. Not only are the compile times even longer, your only option (when targeting #iOS at least) is an IDE that’s showing active contempt to anyone who tries to use it. Such a shame too; the language itself looks like […]

I have bridged my account to #bluesky, so people from there can follow my posts too. I think there are some limitations regarding interaction, but let’s see how this goes 🤞 Here’s my bridged profile: https://bsky.app/profile/arendjr.mstdn.social.ap.brid.gy
