Software Engineer with an incredible thirst for knowledge, who shares that knowledge with others, so that they can become their best selfs.

Interested in #Rust, #WebAssembly, #TypeScript, #OpenSource, #WebDev, #WebDesign and a lot of other interesting stuff.

Let's have some deep conversations about interesting topics. 🙂

I'm open-minded, but also hold strong opinions.

Dare to think for yourself.

Be kind.

So here's the thing with #Microsoft's new #Recall feature:
It's not about Microsoft now suddenly spying on you. They can probably already do that if they want in a much easier way without you knowing.

So please be more realistic!

The far more severe #privacy concern in the age of #remote work is when person A shares their screen and person B having Recall enabled, thereby "recalling" the other person's screen without person A knowing.

So it is a privacy concern between people!

Zed Decoded: Rope & SumTree - by Zed Industries

https://zed.dev/blog/zed-decoded-rope-sumtree

Absolutely fascinating deep-dive into the core data structures the folks at Zed Industries use for their #Zed #editor!

"Currently there are over 20 uses of the SumTree in Zed. [...] The list of files in a project is a SumTree. The information returned by git blame is stored in a SumTree. Messages in the chat channel: SumTree. Diagnostics: SumTree."

Oh, how I love this! ✨

Practical suggestions for building around borrow errors - by quinedot

https://quinedot.github.io/rust-learning/lifetime-intuition.html

If you're struggling with the borrow checker and lifetimes, this is an excellent resource!

In some past toot I've said that Rust lends itself very well to intuition-based learning...

https://floss.social/@janriemer/109415274612140073

...so this learning resource takes the same line (according to its title)! Nice!

Tasks are the wrong abstraction - by Yoshua

https://blog.yoshuawuyts.com/tasks-are-the-wrong-abstraction/

"If we are able to bake concurrent and parallel execution directly into [#RustLang], we no longer have to represent the computation as a type. [...] we would be able to solve the scoped parallel async execution problem directly from the language."

"The success of the Monoio and Glommio runtimes are putting into question whether work-stealing executors are the right fit."

This is what #Rust should focus on! Thank you, Yosh!❤️

We, as a society, really need to stop thinking that

popular == good/best

because it is very often simply false.

#Society #Sociology

janriemer, to ai

Don't be fooled by all the headlines that #AI was the main cause of all the recent layoffs in the tech industry.

This is not the main cause!

The main cause is that #society starts to see the lies of #BigTech and their mass manipulation of people!

C++ will be taken over by #Rust.

What will be the Rust-equivalent for #JavaScript?

I mean #TypeScript is a very good first step, but it's basically the C++ for C.

So in short:
C => C++
JavaScript ≈> TypeScript
C++ => #RustLang
JavaScript => ???

I think it will be a looong way to go, but maybe, maybe we'll see more and more #WebAssembly in the #frontend, but not quite sure yet.

When you read a toot about #Rust:

"Have a compiling topic to share...?",

but it actually says

"Have a compelling topic to share...?",

you know that you have fully oxidized at this point. :ferris:

From their README:

Exploration of the xz backdoor (CVE-2024-3094). Includes the following:

  • honeypot: fake vulnerable server to detect exploit attempts
  • ed448 patch: patch liblzma.so to use our own ED448 public key
  • backdoor format: format of the payload
  • backdoor demo: cli to trigger the RCE assuming knowledge of the ED448 private key

Sometimes, when programming in #Rust, I'm wondering whether there is a little Ferris in my computer whispering to all those 0's and 1's to behave correctly. :ferris:

Otherwise I can't describe the following experience:

  1. Rewrite parts of #parsing a programming language from #nom to #chumsky (the parts that are most interleaved with each other => indirect recursion over multiple non-terminals!).
  2. Run all affected tests
  3. See all of them pass on the first try!

Some people: "Rust's syntax is so confusing to me." 🥴

The #Rust project: "Let's match that confusion with even more confusing syntax!" :awesome:

🤦

janriemer, to rust

Many people say that #Rust is very hard to #prototype with or to #refactor. This couldn't be further from the truth! It is the exact opposite!

Let me share with you one of the most profound experiences I had with #RustLang on a casual sunday - a thread 🧵

I'm currently rewriting my #transpiler from #nom to #chumsky and until now everything has turned out great so far, until I've hit the following road block:
Implementing parsers by using #parser functions that have indirect #recursion.
