After five years of writing, I’ve finally finished my book! It took a lot of energy (and coffee!) to complete, but it’s finally done, and I’m really happy with the result.

My first advice to junior contributors is to STOP using vibe coding for PRs. OSS is always about people more than about code. We don't need more code generated by LLM, we need more people who care.

One very annoying habit of Claude Code 4.5 model is that it tries to replace `foo === false` with `!foo` and claim that it's (a) not the same; and (b) will fix any issue I complain about.

It’s incredible how many things AI agents do right, and it’s incredible how often they can’t solve a certain issue at all. Here’s just a little gem from Copilot.

Did you know that AVIF (the AV1 Image File Format) was supported in all the major browsers (Firefox, Safari, Chrome/Edge)?
This has been the case for almost 2 years at this point.

Self reviews were a good idea before AI but are now a necessity. Don't put that burden on your co-workers. If you use AI, review it 🤖
So I'm reviewing a PR from a colleague that was written for like 95% by AI, and while it might have made his job easier, it's making mine a lot harder because it's riddled with mistakes and issues that I have to now fix, and I feel like I have to thoroughly check every single line of code twice

Suddenly, I got Copilot autocompletion in my Outlook on macOS, and there seem to be no way to turn it off. It makes it totally impossible for me to write even the most basic email — the completions appear too fast and distracts me with mostly unrelated suggestions.

Here, @microsoft.com is basically saying that you cannot have a verified domain on @vscode.dev Marketplace as an indie developer. I _do_ have links to my extensions right on the homepage, but apparently it's not enough anymore.

Some very good points on accessibility of glassmorphism, though the whole article gives me very strong GPT vibes, and lacks any visual examples. I can confirm most points — the default iOS 26 with reduced transparency and motion disabled is essentially unusable for me.

Defaults matter. Remember that people tend to internalize bad UI as their own personal failing, and that people also may not identify as disabled. Combined this means they'll feel bad using inaccessible experiences and not think to check how to fix the problem. www.theverge.com/news/802963/...
