I’ve done workstation maintenance in a previous job. Every part of the Linux centralized management was worse than Windows. We did it to support our coworker’s wishes, but SSSD constantly shits the bed, and having to code (config management) to write some pretty simple rules like default printers is super annoying compared to the Active Directory built ins.

Microsoft’s biggest strength is the Active Directory. Linux user and computer management is a huge PITA.

How would you deal with iowaits in a system like that? I can perfectly burn 100% of CPU time running a poll(), but that’s not useful work…
Tickless means it’s not based on the computer frequency and idle CPUs can stay idle rather than being annoyingly brought into high power mode ever 100 Hz, but it’s still firing interrupts based on scaling timed variables.
They’re now called “Dynticks”
SUSE wrote the vaguely more understandable write up that Linux foundation links to: https://www.suse.com/c/cpu-isolation-full-dynticks-part2/
BTW, the Linux RCU code is evil but interesting: https://www.p99conf.io/session/how-to-avoid-learning-the-linux-kernel-memory-model/
4·5 months agoI actually disagree from a systems engineer perspective: The program doesn’t actually know shit if those bits hit any permanent medium, just that the OS told them “I’ll take care of it” it could be sitting in a write back cache when you save, see the “write complete” and rip the power and that’s all gone now. Basically, I don’t like promising durability when it’s not really there.
META-C :wq!
ESC is all the way over there and my hand is already on the space bar.
Disk Duplicator is a destroyer? Man, I used to image so many drives with DD back in my helpdesk days…
Most of the bolted on services are rather shitty. ResolveD in particular is straight up hot garbage unless the only thing you are comparing it to is nscd. I like shipping all my logs to a centralized service and journald just gets in the way. It feels like they took upstart, bolted on some really crappy daemons,
6·10 months agoHash the image, then assign hash ranges to servers that are part of the ring. You’d use RAFT to get consensus about who is responsible for which ranges. I’m largely just envisioning the Scylla gossip replacement as the underlying communications protocol.
Why? Use something like RAFT, elect the leader, have the leader run the AI tool, then exchange results, with each node running it’s own subset of image hashes.
That does mean you need a trust system, though.
Go ask Red Hat for their sources.
EDIT: I’m a Linux Performance Engineer with 15 years under my belt and I use a Mac as my daily driver. Including when I gasp interface with Linux computers because it’s always a combination of ssh and configuration management of some form. Telling me that Mac users don’t use vim is, on its face, one of the dumbest things I’ve ever heard. It’s a text based interface. I could do it with Windows, but I’m faster on Macs.
But it is UNIX, which Linux is not.
Unless you are on a Mac, then ctrl is META, and META+c gets you to the place where you can :q!
ESC is just too far to deal with when using vi.
Why is anyone requiring an Apple developed piece of software in Linux these days?
It’s still bonkers to me that Kazaa’s network still technically lives on in Skype, though all the Supernodes are in Azure these days rather than the original P2P setup.
