The Kubernetes community is great and all but I'm just not sure I'll ever get used to not indenting YAML lists.

I think one of the biggest quality of life improvements in the last few years is the popularization of setting a dark/light theme based on system time. Makes lots of apps and websites much easier to use in the evening.

I was not pleased with my performance today. Will need lots of sleep to get over it.

I use static binaries so often I forget and get totally derailed by how dynamically linked binaries fail with just "no such file or directory" when they can't find their linked library. I really wish it would print the library it's looking for.

We’re having a Cambrian Explosion of code. People are able to create so much more than ever before
I’ve done it myself and see it with the open source I maintain
But I think the software industry is going to suffer

When I just started out developing I remember being so so so full of ideas that I was coding in my head and wished I could have done programming while commuting / on the bus. With eg a phone. But it was impossible, ofc.
Now it’s possible!! A massive change

If you're spending time thinking about prematurely optimizing Python for performance - fussing over the time it takes to add to a list, or if performance is the primary reason you choose FastAPI over Django, please just choose another language. Please.

I've really tried to read more over the last year, but results are very mixed. I feel like the more I read, the less clarity I have on any particular topic. It's hard to feel like it's doing me any good unless I can produce some kind of output with it. Most of the time it just makes be feel dumb.

TBH, I think this is exactly the reason that I'm not looking forward to software engineering anymore. "Managing context" and doing *more* alt-tab multi-tasking constantly just doesn't sound like a fun job.
In essence a language model changes you from a programmer who writes lines of code, to a programmer that manages the context the model has access to, prunes irrelevant things, adds useful material to context, and writes detailed specifications. If that doesn't sound fun to you, you won't enjoy it.

I always laugh when I hear the "follow the rules" narrative about immigration/migration in the US. A culture of following the rules doesn't exactly come to mind when I think about the US.

My current life stage can best be summed up as "Keep myself busy and don't let my brain think too much because the world sucks and thinking about it just leads to depression".

If you are a programmer and an AI hold-out, and you have some time off during Christmas: gift yourself a 100 USD subscription to Claude Code and … try it. But really try it. Take a week if you can afford it and dive in. It will change your opinion on these tools.
