Typing this on my MacBook, I think about this picture at least once a day. It has completely changed how I see my Apple devices, from loving how tightly integrated everything is to feeling like a prisoner of the Apple ecosystem. Not a single day passes without me making plans for my escape.

I asked the AI to impersonate me, and it did so without hesitation, following my writing about how to write good tests for Vue applications. A couple of thoughts about this:

I get that as a tech CEO, you sometimes have to play the game, and you need a healthy dose of pragmatism.
But how those tech CEOs can look themselves in the mirror kowtowing to this US president is beyond me.
I find it frightening. Is there anything they won't do for financial gain?

Claude 4 is my biggest AI disappointment since GPT4.5. Getting results like this is sobering.

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.

If you're still using ChatGPT but feel you're missing out on the capabilities of today's best models like Claude 3.7 and Gemini 2.5 Pro I highly recommend you check out ChatWise (by @egoist.dev) chatwise.app?atp=maoberle... (affiliate link, but it is my LLM client of choice!). It has MCP support!

A harmful misunderstanding about accessibility is that it's "just" about people with disabilities. This leads to arguments like "We don't want to make UX worse for the majority of people just to cater to the few people with X disability." This way of thinking gets it backward!

😈 Are you a developer worried about losing your job to AI? Don't panic! I have the perfect solution:
1. Rename every symbol in your codebase to random characters.
2. Create a secret cheat sheet mapping these characters back to their original names.
3. Store the cheat sheet somewhere safe.

Do you believe LLMs are intelligent? I changed my mind about it! I think LLMs are "just" that: (large) language models. The way I see it is the following: Imagine you train a toddler to understand language and speak, mixing in texts about physics and mathematics.

Wanted to check out Angular. But it's using not one but two techniques I don't like:
1. Decorators
2. Classes
I'm interested in your opinion, particularly on Decorators, do you like them? I also regularly look at Java (Spring Boot) code and find it hard to decipher because of Decorators.
