Assertions aren’t just checks. They’re diagnostic tools.

If a test doesn't immediately tell you what went wrong, it’s not helping. It's slowing you down.

The quality of a test is proportional to the clarity of its failure.

[Iago Bozza @writeonlycode]

Tests are not primarily about verifying that code works. They are about ensuring that code continues to work as the system evolves. #RustLang #SoftwareTesting #TDD #CodeQuality #Refactoring

Back to the Nand2Tetris course after a break, and I finally completed it! I wrote a Hack Assembler in Rust for the final project. Check it out: https://t.co/vJXGDZKb7P

@killersites I sympathize. But: college shouldn't be a vocational course to begin with, so, as you've hinted, we shouldn't expect it to primarily prepare people for jobs. And: having a college degree signals employees that you are hard working, and that has some economic value.

As I'm re-reading the #React docs, I'm impressed by how much they've improved! At the same time, it bothers me that they suggest components should be pure functions, even though any component with state isn't truly a pure function...

How to master Linux command line

[Iago Bozza @writeonlycode]

Ohh, I really like that we can run TypeScript directly with #bun. It also comes with a test runner and bundler included, in addition to the package manager, of course. Neat!

[Iago Bozza @writeonlycode]

Taking a look at #bun today. Looks cool! Easy to install, everything works very smoothly, and a lot of things integrated in the CLI. The #JavaScript world really needs something to replace Node & it's million build tools and bundlers...

#golang exercide of the day done at @exercism_io! 48/#100DaysOfCode

[Iago Bozza @writeonlycode]

@AdemoyeJohn Philosophy!

[Iago Bozza @writeonlycode]

Ok, after a little break, coming back to #golang exercises at @exercism_io ! 47/#100DaysOfCode

[Iago Bozza @writeonlycode]

Huh. This was a bit harder than expected. But it was fun to see the nuances of the % operator in #golang! Another exercise at @exercism_io today! #100DaysOfCode
