I find that stuff that it offers over a normal Hyper-V VM is stuff that I don't need, leaky abstractions galore.

I don't get the point that you're even arguing. Are you saying that 60 is fine as a default? Or are you saying that people should even think about vm.swappiness because it doesn't matter? The alternative here is to disable swap completely, that's what started this whole thread.

> What do you think this value of 60 means?

Some arbitrary number.

> At 0, the kernel will not initiate swap until the amount of free and file-backed pages is less than the high watermark in a zone.

I don't see a reason why the default shouldn't be 0 then on modern systems.

Maybe, but it still there and probably has a different value between distros as well. Default value is 60, what is that good for exactly?

If you're in a position where you still want swap to be there, but only used in extreme situations, then you should set it yourself. Otherwise disable swap or switch a language.

Surely as long as it is all in memory these pauses are not going to be that significant, details like that should be left for the language devs to optimize.

You can tell an average Golang user to use mutexes, you shouldn't be telling them to lock memory manually.

I think discussing it in a vacuum is pointless, it should depend on how much memory you have. You can have a swap on, but with a low `vm.swappiness` number.

I was looking for an answer to this when it comes to using Edge password manager in particular, it uses Windows Hello as far as I know and while it does make 'synced' passkeys they don't seem to be usable anywhere than the original machine. Useful when reinstalling Windows at least.

https://yourpasskeyisweak.com does not mention Edge.

True enough, but in my experience it's not really much of a problem because if I'm not doing Nix, then I'm doing containers which are widely available.

What can be a problem is muscle memory, when you expect it to autocomplete one way and it doesn't because something you want now shares first two or three letters with something else in your path. That's where FIGNORE comes in.

    [user@nixos:~]$ which grep

Basically, it is still in your environment, so I don't see how he can claim that this problem doesn't exist in Nix, unless you use flakes like a proper Nix afficionado.

I've yet to encounter a site that allows to enroll a FIDO device without setting up some other form of 2FA and for me it's TOTP which are kept in the app.

New comment by xaduha in "IPMI"

xaduha — Tue, 03 Sep 2024 06:54:12 +0000

IPMI and other solutions are nice, but what I would like to have is a standard serial interface to an UEFI shell running at all times. How I access that serial port should be my problem.

New comment by xaduha in "IPMI"

xaduha — Tue, 03 Sep 2024 06:36:35 +0000

Since one of the solutions was to reboot "up to 15 times" I would imagine so.

If it was a short-lived QR code generated on your phone, then maybe. But the whole point of MIFARE Ultralight EV1 cards is that they can't be cloned. It's for repeated use, not for printing and using once.

Quake II soundtrack is still in some sort of copyright limbo. It's easy enough to find on Youtube, but it's not on streaming services as far as I know.

EDIT: maybe it's getting sorted out, there's even a fricking vinyl release

It's for C/C++ as author says, not just for C. And even if you're using Qt and write mostly QML you still need some C++ and it's much easier with code completion. I'd rather use VSCode than Qt Creator for that and I'm certainly not going back to vim.

They had Twitch integration since the beginning and judging by some accounts they weren't prepared for how much that would be in demand on full release. Each user can see streamer's full inventory and journal, vote on dialogue options when asked, etc. Surely Steam isn't handling that.

Never heard of tush, but I've used cram for a while. I think tools like that are good for some stuff e.g. unix pipes, but complexity catches up with you very fast if you try to use them for something non-trivial.

New comment by xaduha in "Why did Nix adopt Flakes?"

xaduha — Fri, 16 Jun 2023 21:29:41 +0000

I'd start by using Home Manager which is a way to use nix packages in a sensible manner on any distro.

Completely stop what? If you encrypt your drive, then all these attacks fall into a category of 'continuing using a device after someone tampered with it'.

If you're that paranoid, then you can buy anti-tamper stickers. I'm not joking BTW, I think some of those are pretty damn impressive.
