imho at least qemu would need snp and tdx emulation in upstream for like testing patches. i mean most have x86 so even rigged emulation would do the job for trivial patch testing

#Amaranth sounds like a name of a black/death metal band from Scandinavia but is actually pretty neat hardware (#FPGA) synthesis framework:

Splitting my pull request. For v6.10 not yet fully finished/polished but the idea is to have simple script to create the PR from signed git tag and then have a few #aerc templates for each subsystem:

Two first I did for keyring and trusted key did not yet use this scheme but learned along the way that I need to scale a bit. Slowly figuring out how to do this properly.

(speaking for myself here) One of the cooler things about Google is getting just the slightest glimpse of the power of some of the tooling your wizard coworkers use.

https://perfetto.dev/ is one of those very cool tools. It's like kernel shark, but has really powerful SQL capabilities. It's well configured for use with Android and CrOS, but with classic Linux environments it can be a little daunting. So here are my notes on using it for upstream kernel development: https://gist.github.com/johnstultz-work/0ec4974e0929c4707bfd89c876ae4735

In colloquial computing Finnish the work for a cache is "kakku", because it's similar in pronunciation. Kakku means "cake". Thus, in Finnish people ask each other how much cake their CPU has.

Language is funny.

Co-authored an update from the @MastodonEngineering team with my friend @renchap - a sneak peek at what is coming in 4.3 (and looking ahead from there). We'll aim to make these updates a regular feature for the blog. Let us know what you think! https://blog.joinmastodon.org/2024/05/trunk-tidbits-april-2024/

IMHO, good way to protest against bully business practices of AI: exit the most consumer oriented social media. I think it was good time finally quit Facebook fully given the trends. I'm not perfect. I.e. I have still some commercial social media like Slack, Youtube and BlueSky but at least the most heated stuff is gone, or I never was there anyway.

E.g. I think I continue to build my career without LinkedIn, and find the jobs that fit me better through traditional methods of job finding (talking to friends, getting contacted by friend, sending queries and the usual). It is time to go #offtheradar :-)

I wish there was USB-stick that would send one single key press when the button is pressed. That's all it would do.

OK, so WFI on RISC-V is not detemistic! It can be same as HLT (x86) or WAIT (ARM) but could also be nop 🤷 Beyond me tbh. #riscv

Everyone should immediately stop contributing to the stack overflow and its network. The human touch is what made it unique. Delete your profile from SO AND all your answers. Freeloaders are making money out of human contributions.
