Problems do not arise when let's say daemon logs "1024 MiB". Then can be quite safely assumed the aligment with ISO/IEC 80000-13.
However, if the same daemon emits "1024 MB" instead, I need to download the full source code and study it enough to be sure what is what.
Obviously this mess applies also to hardware.
It is a cardinal sin to break backwards compatibility just plain randomly. Should be dead obvious for any legit engineer that instead it would have been better to invent a new unit for base-1000 sizes, instead of corrupting base-1024 sizes.

@karinjiri it's sick, agreed, but it is no nearly as bad as introduction of mibibytes and changing sizes as being ambiguous entities :-)

Whoever thinks that getting cute by replacing precise timestamps with "1 hour ago", "3 weeks ago", "6 months ago", "recently" etc is a good idea:
STOP IT!
I am particularly glaring at you, github! I don't know if you did it first, but so many other people copied this blight on humanity from you.

@thejpster Cool, and pretty clever work! Just thought that a research group matching country, size-to-fit OS and using Rust so at least three correlation points :-)
Heh, that "nobody's using XXX" always does the triggering job for me :-) Actually, if I consider any tech conference, I'm *most* interested on presentations where someone is doing something with tools that nobody's using. That's why I e.g. went to see a Servo presentation back in LinuxCon EU 2014. I went to see it exactly because nobody was using Rust, and thus it grabbed my attention. Popularity is not really a recommended way to approach tech really.

@thejpster Why anyone would even care if any possible tool is used by anyone else? In commercial setting, anyone else usually means competitors, so an overlooked tool is merely a competitive advantage. No logic in that comment tbh as the outcome is for the most part irrelevant :-)
There's a really cool hard RTOS framework from Sweden focused on Cortext-M, and more recently ported to RISC-V, based on hardware priority based scheduling. Wonder if they are basing on that: https://rtic.rs/2/book/en/. Met the creator randomly about a year ago (was visiting at the local university in Tampere, FI), and he gave a great presentation about their research groups work. Was quite amazed.
Its task creation and other shenanigans are essentially a small domain language based on Rust macros and end outcome is bare-metal blobs.

Looking at statistics and error ranges and not much can be said about outcome:
https://ig.ft.com/us-elections/2024/polls/
Neither do I believe that world ends to either outcome.
We've have had in Finland some crazy and/or drunkard dictator who wants to destroy the planet leading the neighbor country for most of the post-war history, and usually terms have been "up-until-being-a-corpse", not four years.
Not going to tell, which of our neighbors I'm talking about, just in order not to point any fingers :-) For most it would be better probably to put more focus on elections where you have the voting privilege in the first place.

Phew, all biometric and also ThinkShield and ThinkCloud shenanigans disabled from ThinkPad BIOS.
I never use biometric anywhere because in the end of the day it is just obfuscated clear text.

Obviously this has some security advantages too I guess. Given partitioning lot's of cross-VM side-channel scenarios are ruled out. I don't think you can e.g. use any Spectre derivative between two guests in Jailhouse (academic guess, I have not read its source code properly).

I don't like hypervisors where guest is like an extended entity of a process (/dev/kvm).
Or like I get that at a data center where you lease resources but actually the best possible scheme running VM's at home is partitioning.
Good example is creating a VM running Windows with optimal perf, which requires tons of knowledge about even things like huge pages and how to control them and stuff like that. All that complexity comes from melding the process be a bit like a partition of resources instead.
So when this came up, I thought that this is exciting exactly for home use:
https://github.com/siemens/jailhouse
I discovered it, if I recall correctly, OpenSource Summit or Plumbers when the band wagon was at LA 2018. Totally made sense for me because it kind of does of the shelf the best defaults for home use.
I wonder what happened to this project, is it in upstream or doing any progress? Not around a machine with my dev stuff to check this so thus not checking myself :-)

Question #Asahi #Linux.
I bought in June a dock with M.2 slot. but at that point Asahi at least required some extra dance to get booting from external drive.
I might have tried it but gave up or did not get not working, cannot recall anymore :-)
Anyway, is this becoming a feature in Asahi or at least in the roadmap?
I have the heftiest 6/4 core (16/16 GPU/AI) version with 32 Gb waiting for becoming ARM build machine during days and studio for bad music during nights ;-)

jarkkoCasio. The battery has lasted 1.2 years so far, syncs the timezone automatically when country changes via bluetooth, shows arrived messages and calls, has a step counter and other rudimentary sporty features.
Have been considering while buying sports watch from Suunto like for having navigation when hiking in the woods but this really has delivered incredibly well considering how archaic it is :-)
