I am also talking about the behavior of updating dependencies the second they are released. It's culture now in Android Dev. I once saw a project utterly frustrated because a Kotlin update broke their workflow. Maintainers were quite loud, but refused to downgrade. Compatibility requires patience

But do you really need to be on the alpha, betas, or today releases to fix tech debt? Look at any public project and see the pre release usages. It's not healthy!

I said it once, I'll say it again:
You might think you're doing your project a favor by always upgrading to the latest AGP version.

What you do instead is break the project for everyone who has not downloaded the latest IDE.

This is pain

Casey Muratori pretty much sums up how I feel about LLMs for coding:

"The AI will always be useless for me. I physically can't get what I want from programming when AI is involved, because what it is doing is robbing me of the experience that I wanted to have and the knowledge that I wanted to get"

Let me tell you! It's a rollercoaster; I did not expect some of the things that happened, but I learned a few things. I thought it would be a quick benchmark and a recording, but I spent much more time here. Will record the results soon!

Are you okay with being mentioned in the video?

Benchmarking in progress, recording video today 😎

Oh, I did not expect to have so much fun building the IDE tooling/integration for Compose Hot Reload 😍

See the small floating toolbar when a session is present, even allowing you to reset your UI state!

Next video: Benchmarking! Would you be interested in sharing your code for comparison? The shader should be really fast, but I did not measure it!

Pretty sure some of you folks might enjoy working with it as well 😍

🌴 Compose Hot Reload has finally reached Beta!

I started the project by accident, and it's been so much fun to work on. Time for a small break 🌴, and we'll target the first stable release soon.

👀 not aware of most of the words you wrote. Might be a symptom already? I'll ask around at KotlinConf, so maybe someone has seen it! I got you, mate

That would be awesome! Feel free to send it to the Munich JetBrains office with c/o Sellmair. Don't worry about the packaging, it's usually pretty stable 🫡👍
