i run https://howtotestfrontend.com, a site full of resources and tips on how to test React frontend code.
i would guess most links i post are either about testing, frontend development, typescript, etc etc.
i also post interesting links i found around the web. the only site that is mine is www.howtotestfrontend.com, the rest are just ones i think might be interesting on hacker news.

OpenAI's internal documents predict $14B loss in 2026 according to report
Yep. I think there are so many new apps, when I run a `npx skills add ...` , the list of what tools (like claude code, open code, etc) to install skills in is getting larger every time I use it.
100%. its a horrible code smell, and AI loves to jest.mock (or vi.mock()). (The most recent blog post on my site covers this as one of the things to look out for in AI generated tests...)
in JS (with Jest/Vitest) it is far too easy to call mock()...
Has anyone got any good resources for something like this? I haven't touched C in years, and never worked on anything game-like. But it does look like a really interesting project to start something like this.
just saw this today - "whenwords, a relative time formatting library that contains no code." I wonder with AI this will become a popular thing soon that we see other 'libraries' doing... provide good specs, leave it to AI (And trust ai) to interpret
If GH has an issue, it seems to always be around 4pm or 5pm GMT. I'm starting to think that i should avoid any planned production releases around this time.
while this approach is useful, i think the diff is too small to catch a lot of bugs.
i use https://www.coderabbit.ai/ and it tends to be aware of files that aren't in the diff, and definitely can see the rest of the file your are editing (not just the lines in the diff)

Adding some final bits to some new vitest browser mode content this week hopefully.
