Hey @bsky.app, If I don't follow Discover, please don't show content from it in my "Following" feed.
I have different feeds *for a reason*.
At least give me the option to choose if I'd like content from other feeds instead of choosing for me.

GREAT example by Yuan
Games is actually a fantastic example of what happens when you remove the obstacle that everyone thought was the biggest hurdle in building a game: needing to build a game engine
Easier to build games… still very hard to build great games!

I am looking for a short piece of heavy metal music to license (paid) for a project, and I would love to get it from a small indie band. If anyone has any recommendations, I am all ears. Reach out here or at [email protected].

The feature is almost ready to be called done. The next (and final) maturity step is to designate it as officially "stable".

It seems obvious, but this is one of the big mental shift you can have to improve as a developer.
@effect-ts.bsky.social it's an example on how, if you embrace this shift, the quality arises and you start thinking more on the what and less on the how.

You don’t write code anymore. You describe what you want done.
The code writes itself.

No, you didn’t “clone” a billion-dollar business. You created a landing page similar to it. That’s all.

I get that it's a skill issue on my end, but damn if it doesn't feel like every time I try to use React I feel like everywhere I step there's a rake waiting to bash me in the face
I feel like, somehow, knowing JavaScript actively hinders me from writing React, which feels weird and wrong

Backend TypeScript apps can feel like a mystery when things go wrong. @effect-ts.bsky.social has observability baked in to help monitor each step of a program and identify issues. Here's what I learned while setting up its tracing features.

Sometimes you get "UnkownError"s;
so you try the simulator and gives the result you expect;
you try the CLI and it works;
then you apply the changes with terraform but it fails.
