@ikkeT joo pistin päivityksen kirjanmerkkeihin jos tulee joskus tarvetta, kaikki vinkit otetaan aina kiitollisena vastaan, kun ei tiedä koskaan :-) distrobox oli tuttu, mutta toolbx ei.

@ikkeT mä haluisin itseasiassa oppia kunnolla quadletit ihan raaka-podmanilla. Parempi investointi pidemmän päälle. tilasin sitä varten ihan kirjankin: "DevOps for the Desperate" ;-)

Just an observation but if considering testing ARM64-Linux, Apple is actually a “budget choice” compared to:

  1. Low-volume Linux ARM64 laptops (few available).
  2. ARM64 server racks.

Especially if you take -1 gen Apple hardware, which you can get for bargain prices pre/post the next WWDC ;-) The laptop seen in previous screenshot is M1 Pro, and it is quite nice and fast , and that is even -2 gen.

aika harvoin teen muuta "käyttäjätilan" (toi lienee oikea suomennos) koodia kuin jotain joka suoraan tai epäsuoraan liittyy kernelimuutosten testaukseen :-) sen takia qemu ja libvirt hoitaa homman aika paljon paremmin kuin kontit...

@ikkeT tässä on oleellista on https://asahilinux.org/ sinänsä mulle käy mikä vaan, kunhan on systemd eikä ubuntu :-)

applehan on deskaritason (ja siitä ylöspäin) arm64-raudassa budjettivaihtoehto. muut vaihtoehdot on ylihintaiset linux-laptop-valmistajien tuotteet tai monen tonnin serveriräkki :-)

#note to myself, not throughly thought out...

Useful #kernel feature for #hibernate might be a file that would tell the number of pages required for hibernate.

The "O-figure" for hibernate is AFAIK O(n+sqrt(n)) but exact number is dependent on kernel internals but in theory could be calculated by simulating the process without committing.

Instead of swap it might also be useful to have "spare" volume of ~100 GB for doing hibernate and e2scrub type of operations, which could have its own design for encryption etc. Swap for swapping overcommitted memory more than few at most GiB is not that useful these days.

Just an observation, not a political opinion, but it might be that Mr Biden and Mr Trump are the oldest duel in any presidential election of any democratic country in the world ever in the history of mankind.

On the bright side, it means that US has no age racism I guess then 🤷

I feel like if you are going to take time to talk to Tucker Carlson, you deserve everything that's about to come to you.

I do, however, hope nothing happens to the users.

Despite being somewhat controversial figure, I really don't think that either of these would have been appropriate end outcomes for Mr Assange:

1. Guantanamo Bay
2. ADX Florence

This is not same as saying that I would fully support all the choices and values of the person in question.

I had my first ever Mandela Effect experience, I recall seeing reports of his death like half years ago.

Anyway, congrats to Mr Tanenbaum, well deserved! Only thing that surprises me is that why he did receive ACM award earlier than this.

NUMA Emulation Yields "Significant Performance Uplift" To Raspberry Pi 5

Engineers at consulting firm Igalia are exploring NUMA emulation for ARM64 (AArch64) due to the potential of "significant" performance uplift as observed on the popular Raspberry Pi 5 single board computer...

@mikebabcock i have zero plans to use hibernation in my hosts but i'm interested to test it as a kernel feature :-) and generally i want a common image that works for my host system and test targets (usually VM's ,sometimes NUC's).

@mikebabcock I'm doing this partly to research what would be optimal configuration to enable hibernate, and possibly try out encrypted hibernate patch set, which never landed to the mainline. So I'm doing both reconfiguration for my host system and designing something for test target VM's at the same time :-)

One observation is that probably it is better to encrypt per logical volume than encrypt the physical volume because then the partition is reachable for so called restore kernel. I've previously encrypted the physical volume and created logical volumes inside it.
