What is MAX_PAGE_ORDER value on x86-64?

The "fallback value" is 10 (right?) so kmalloc() can allocate at max 2**22 bytes i.e. 4 MB I guess, unless MAX_PAGE_ORDER is larger.

@mupuf Yeah, I'm super extra careful on my words if I have not worked with some code for myself but it might be true :-)

I'm quite sure at lest that Red Hat has nothing to do with this...

Generally I think that Net IF code would be exactly in the core definition of a Rust plausible situation: you have incoming and outgoing data from potential and actual adversaries bombed to your system at high rates.

7️⃣ Here's the 7th installment of posts highlighting key new features of the upcoming v257 release of systemd.

The graphical login prompt you see when your computer boots up is a sensitive UI: typically, when starting to work, without much thinking you'll type in your username and password, expecting it log you in and provide you with your desktop session. However, what if someone just opened a website in a browser in full screen mode with contents that just *looks* like your login screen, …

Trump does not have a follower but also: now that he gets his four years that zeros out "what if" speculation. History will remember him with brutal honesty now and he won't get martyr reputation, which could be the accelerator for a follower.

If he had lost, his influence might had radiated longer to the future.

@lkundrak @ljs @oleksandr @monsieuricon @vbabka I think GPG like a vacuum cleaner. You don't need to understand always the exact mechanism: just make sure that every key in .gnupg/private-keys.d starts with "Key: (shadowed-private-key", which means that it some kind of reference to the key inside smartcard. And if it stops working, take the attitude on fixing the config files as your were giving a proper kick to your vacuum cleaner 🤷

@ljs @lkundrak @monsieuricon @oleksandr @vbabka No ChatGPT used on it just monkey on the keys (aka me) trying out random combinations of options until it started worked again (no idea what the options actually do) ;-)

@ljs @lkundrak @monsieuricon @oleksandr @vbabka oh forgot https://codeberg.org/jarkko/skeleton/src/branch/main/.gnupg ;-) scdaemon.conf is something that i added based on random googling as gpg-agent suddenly stopped working last Spring.

@oleksandr @ljs @lkundrak @monsieuricon @vbabka i cannot recall anymore why it is like it is but do not want to touch it because it seems to be a steady performer in all possible distributions ;-)

On a new system before running that I do 

gpg --recv-keys 3AB05486C7752FE1
gpg --edit-key 3AB05486C7752FE1

And in interactive prompt trust and give “ultimate trust” to my key (whatever fuck that means but seems to be essential). Then I run my bootstrap script.

according to estimates there was something like 10-20k troops. considering that a modern missile can cost like million or more supplying headsets is cheap bargain. maybe pornhub or similar site could even sponsor the subscriptions.

it is hybrid warfare

why wifi is so sensitive? year and decade after it always seem to oops. not blaming anyone really just wondering...

it's not usually even wpa supplicant but straight up kernel oops...

i mean it can be hardware/acpi/firmware etc. that causes this...

Or maybe WiFi is a feature that we should rewrite with Rust? I mean regular oops is at least evidence of regular memory corruption. Even my non-geek friends seem to "know" that Linux always blows on suspend, so it is also kind of a "brand issue", at least in non-Android client use cases.
