Social media platforms at the moment where I have an account:

1. Mastodon
2. Facebook
3. SoundCloud
4. LKML ;-)

Over the summer I've just made analysis does a platform provide measurable benefit for my life. This caused me to scrape away LinkedIn and Twitter for instance. I can literally feel how much more peaceful I am and a lot of anxiety has gone. Social media is IMHO a digital narcotic.

I used to have Nitrokey Pro in the past with paper printed backup of my master key as a set QR codes. I'm now in the middle of migration. I actually set the passphrase accidentally to a subkey and now I'm clueless how get rid of it. I just want to understand before progressing forward.

IMHO, both #AMD #SEV #SNP and #Intel #TDX are quite questionable technologies given the narrow span of user base limited only selected large companies. Very few maintainers can test any of the patches.

We should demand providing affordable #hardware for these technologies like NUC7 in the past for #SGX. IMHO, a technology should not land to the kernel in most cases, unless a college student can afford to buy at least some hardware for testing the tech in question.

I'm wondering why there is so little fuzz about this considering how much FUD was spread all over the community about #TPM's in the past.

What confidential computing would desperately need is new versions of Intel NUC (or is it now Asus NUC) and new UDOO BOLT for testing SEV-SNP.. Otherwise innovation will not exist.

@krzk @vbabka I'm migrating my keyring to yubikey atm. I have two of them. But still I don't want to proceed on that before I know how the basic password management works with OpenPGP. E.g. I don't even know how to see whether a key has a password set or not in the first place :-)

I’ve ranted lately a lot at #LKML about how #kernel #Bugzilla’s role in the #development #process should be defined better in the #documentation. #linux

Starting to understand why #OpenPGP has never really dominated :-)

I wonder what is the best practice to remove #passphrase from #OpenPGP subkey. I’m using #gnupg2. I’ve spend hours on this and still not able to do it :-(

I.e. I have this:

$ gpg -K
/home/jarkko/.gnupg/pubring.kbx

And I want to remove passphrase from #ed25519 #authentication #key.

Maybe a few years and #Apple will be out with #iTape, the appliance for time machine backups :-)

Looking #LTO #tape #drives :-) I might get one at some point to support my #NAS. There's a lot of options below 1000 EUR range, and tapes are neither that expensive, when archiving frequency is maybe few times a year.

Xfig looks still hot tho :-)

Learning #Inkscape in order to substitute #LibreOffice Draw. I moved into LibreOffice Draw some years ago from #Xfig, only because it had turned into legacy. However, I've learned over the time that the structural complexity of actual diagram tools tend to take my focus away from the actual problem, and more into fiddling between the choices in the tool itself.

I created my own12 cm x 9 cm template, which are pretty good starting point metrics (and aspect ratio) for many situations, especially when you have to embed pictures. These metrics are also in good harmony with the primitive (but functional) connector tool of Inkscape, and on keeping complexity of the diagram low :-)

... was not fun to not reach the machine for some time lol

… the most important thing to remember post installation :-) #systemd

$ sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target
[sudo] password for jarkko:

Installed #Debian 12 to my #desktop #PC (migrated back from #Ubuntu). Recent switch to #Intel #ARC #GPU considerably lowered the barrier.

@linjaaho Pitää todeta, että mullakin on nollatoleranssi sikäli, että en naura misogynisten tai rasististen juttujen mukana, vaan vaihdan seuraa :-) Uskon, että tuollainen kuvakaappaussota pikemminkin vie rasistisia viestejä eteenpäin, koska negatiivinenkin mainos on mainos somessa.

Something that has probably existed forever but I just learned. You can pass status=progress to dd, and it will show progress. #note

@linjaaho Epäsuosittu mielipide ehkä, mutta mielestäni kaikkeen toksiseen läppään ei pidä puuttua, vaan sille pitää kääntää ainoastaan selkänsä. Siihen pitää puuttua vasta silloin, kun se aiheuttaa todellista henkilöön tai yhteiskuntaan kohdistuvaa uhkaa. Nollatolerenssin kanssa on menty ehkä vähän överiksi, tai se on otettu vähän liian kirjaimellisesti ja laput silmillä.
