@kuksenk0 @jjenkov First step for performance is to ensure the CPU is busy e.g. prevent IO or memory stalls. The following step is ensuring the CPU does useful work.

Hey #PulumiUp, here's a quick sneak peek at Besom, Scala SDK for Pulumi that my team is building at
@VirtusLab:
https://t.co/g3nvgZTy7t
It's probably the first community-driven SDK and we've gathered some insight while building it and we like to share.
@PulumiCorp-Rust maybe?

@garybernhardt I'm excited to stop writing code and start writing machine-readable specifications of precise intended behavior

Dear 2023, the bar is low. Please don't disappoint.

Ukraine's @ZelenskyyUa, speaking in Polish, has sent Poland a message to mark its Independence Day

"Ukraine and Poland together. We are relatives, we are free. Ukrainians will always remember how you were beside us, how your people welcomed us, helped us"

@DrPhiltill Electronics are the deepest witchcraft as far as I'm concerned. We take sand, put a potion on it and shine light on it through a special drawing, and then write spells to make the sand do stuff, powered by lightning. Fucking wild

@kubukoz If you try to draw a perfect rectangle, but get it slightly wrong, people will notice and it will annoy them. So instead you draw it so bent and skewed that it doesn't even look like a rectangle. It becomes a conscious style choice.

This is the same for CSS.

@kubukoz Well, obviously... the ultimate solution is a remote desktop. Or two... ;)

Imagine the implications for climate change if it turned out there were special rocks that just sat there giving off heat you could turn into electricity.

@reibitto @RosaCtrl Changed my mind. Feel free to ask why ;)

[Rafał Sumisławski 💙💛 @sumislawski]

@reibitto @RosaCtrl Use java 8. Don't ask me why.

[Rafał Sumisławski 💙💛 @sumislawski]

@reibitto @RosaCtrl "theFile" is where you put the path to the output file. The trace will be written there, and then you can open that file with chromes tracing. Keep in mind that if you have a project with multiple models then you want to set different files name per module.

[Rafał Sumisławski 💙💛 @sumislawski]

@RosaCtrl @reibitto You get a flame graph showing which files comple slow and why. It's usually macros, shapless and typeclass derivation.

Restructuring the project might also be helpful as it can enable parallelisation, and give you sort of "checkpoints" so you avoid recompiling the whole thing.

[Rafał Sumisławski 💙💛 @sumislawski]

@RosaCtrl @reibitto I recommend using

scalacOptions ++= Seq("-Yprofile-trace", ”theFile")​

And then opening the file with chrome's chrome://tracing/
