hmm... https://www.phoronix.com/news/Linux-610-TPM-Encrypt-Integrity. so it is not yet pulled so no need to announce in the current state "unfinished work" (by definition, given that it is not pulled) ;-)

I'll try to get asymmetric keys soon out which cleans this stack up further as a side-effect. If this did not make into 6.10 then I'll just add it on top of that patch set.

The single biggest issue in confidential computing is still. that there is no legit way to deliver cryptographic proof to client/browser inherited from CPU attestation. i.e. a x509 certificate. and so that it is vendor-neutral. not sure if even @signalapp can do this. who cares what you run in the backend if you cannot prove it.

this is still somewhat solid reference: https://www.decentriq.com/article/swiss-cheese-to-cheddar-securing-amd-sev-snp-early-boot

I wonder if it would make sense to elf stamp kernel images with some sort of. identifier to check where the image is at in the mainline reflecting to the latest of https://docs.kernel.org/process/cve.html. Or maybe this already exist. It would make in the mainline perhaps because then you could detect "too old" when running multiple distributions.

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

SDL3 Adds PipeWire Camera Support

Adding to the growing list of features coming with the SDL3 release for this hardware/software abstraction layer commonly used by cross-platform games and other software is PipeWire camera capturing support...

#GNOME 47 Desktop Environment Is Slated for Release on September 18th, 2024 https://9to5linux.com/gnome-47-desktop-environment-release-date-slated-for-september-18th-2024

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

working on RFC patch for TPM2 asymmetric keys (will use null seed encrypted session) for supporting x509: https://git.kernel.org/pub/scm/linux/kernel/git/jarkko/linux-tpmdd.git/commit/?h=tpm2_key

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.

this looks cool: https://aya-rs.dev/

(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.

Windows NT guy here supporting Windows95Man in #eurovision #esc2024

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! #MastodonAPI #SpreadMastodon 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 :-)
