Instead of stopping at the first failure, `expect.soft` reports *all* failing assertions in a single run. This allows us to fix all the problems in one go. Have you already used `expect.soft` in your tests?.

A useful new(ish) @vitest_dev feature I almost missed is `expect.soft`! It allows us to have assertions that don't terminate test execution when they fail. This helps us iterate more quickly on failing tests.

There is an Austrian proverb that roughly translates to:. > Before the law, everybody is equalβbut some are more equal.
Update: Apparently the Delaware state government, realizing what's at stake, has been working to ensure that Delaware remains a safe place for startups to incorporate, and it's now a valid option again.

What the heck is going on with tech people? A man who cries must be a weak leader? I thought we had left this kind of thinking long behind us.
Europe is intend on proving every over-the-top stereotype that America is throwing at them at the moment. Weeping in response to Vance's call for free speech and democratic accountability on mass immigration validates every accusation of weak leadership imaginable.

And don't get me started on natural performance fluctuations that happen in the life of humans (e.g., because of the death of a loved one, break-ups, childbirth,. ). Hire when it hurts, and fire when it really hurts, but not sooner!.

Firing 5% of "low-performers" means a) you need to come up with metrics for rating your employees, which leads to b) your workforce focusing on gaming those metrics (Goodhart's law).

I'm convinced that most tech companies are massively overstaffed. Yet the recent announcements of multiple tech companies to fire 5% of "low-performers" ultimately get it backward. Overstaffing needs to be fixed with better (and less) hiring and not "better" firing!.

I wonder how much of this is because of AI versus because scaling development teams is incredibly hard. There are 5 person developer teams out there who run circles around many 50 and some 500-dev companies. Always was like this, not only since AI.
Just talked to a business owner who reduced his dev staff from 18 to 3 using generative AI. Claims he's getting the same velocity with only 3 devs. 2025 is going to be wild.

100% agree! kebab-case file names are the way to go!.
V0's system prompt specifies these naming and casing rules. I agree with all this. For years, I used PascalCase for React components. But I now I use kebab-case instead to avoid casing issues.

π Is using non-English words in code always a bad idea? For the longest time, I thought so. But recently I changed my mind!.

Using German, French, Spanish, or other non-English terms in code? Sometimes it makes sense! Explore when to keep native terms for clarity and avoid translation pitfalls.

Finally, after many years of being slightly embarassed by it I found the time to revamp my personal website! Now using Astro as the framework and React as the templating language. Still very much work in progress but way better than the old version.

π―this. (With a small addendum to #1 when working with microservices: replace local DBs and SQL scripts with OpenAPI specs / contracts.).
My preferred development workflow for 2024:. 1. All devs have their own DB instance so we donβt conflict with each other. The DBs run locally, and can be reset via static SQL scripts via a single command. The SQL scripts are committed to source control. This way, we can code.
