Atemu OP , 5 months ago to linux in backdoor in upstream xz/liblzma leading to ssh server compromise

We know that sshd is targeted but we don’t know the full extent of the attack yet.

Atemu OP , 5 months ago (edited 5 months ago) to linux in backdoor in upstream xz/liblzma leading to ssh server compromise

Arch is on 5.6.1 as of now: archlinux.org/packages/core/x86_64/xz/

We at Nixpkgs have barely evaded having it go to a channel used by users and we don’t seem to be affected by the backdoor.

To the person receiving the money, it is worth it. Else they wouldn’t be doing it.

Atemu , 5 months ago to technology in Majority of Americans now use ad blockers

Yes and that’s precisely the point. You can make the decision not to pay and there are good reasons to do so (I do so too) but you must recognise that someone is still not getting paid for their work.

Cool story bro but you clearly still didn’t even read the first sentence of what I wrote.

Note that the diff does not necessarily correlate with the amount of data that changed, not how much additional space the snapshot takes.

Atemu , 5 months ago to technology in Majority of Americans now use ad blockers

What a great argument! You didn’t even read the first sentence…

It isn’t an ethical concern and hasn’t been since the 90s.

You’ll have to explain to me how not compensating someone for their work has been ethical since the 90s.

Atemu , 5 months ago to technology in Majority of Americans now use ad blockers

Security knowledge and ethical concerns are two separate things. Whether we like it or not, we pay online creators through private data we must give to entities who will use it against our best interests.

Size of diff between btrfs subvolume and snapshot is 11GiB

WDYM by “diff”?

Also forgot to mention but if you want to know what’s taking how much space on your btrfs, try btdu. It uses a sampling-based approach and will therefore never be 100% accurate but it should be quite accurate enough after a little bit.

This is the way. You need to check whether CPU and package are mostly in the highest C-states they can be. If not, you’ve got a task or IO device causing a lot of wasted power.

Atemu , 5 months ago to linux in Please share your power optimizations to maximize battery life

I don’t see how undervolting would result in power savings on modern CPUs if you’re not up against clock limits as the CPU would simply boost higher.

As per btrfs fi df /home, used space is 82.86 GiB, not 83.21 GiB.

That’s just used data. The global used metric likely incorporates metadata etc. too. System aswell as the GlobalReserve are probably accounted as fully used as they’re, well, reserved.

As per btrfs fi du -s /home , used space is 63.11 GiB.

<span style="color:#323232;">     Total   Exclusive  Set shared  Filename
</span><span style="color:#323232;">  63.11GiB    13.64GiB    49.01GiB  /home
</span>

While according to du -hs /home, 64GiB is used.

Likely compression or inline extents. btrfs only reports apparent size to du and friends unfortunately.

Also, maximum space used should be close to 72 GiB as per btrfs fi du -s / and 73 GiB as per du -hs /, if btrfs fi usage includes all subvolumes . ‘/home’ and ‘/’ are on separate subvolumes.

Your home has a lot of shared extents which indicates to me that you have at least one snapshot of it.

You also wrote 13.6GiB of new data to your home since the snapshot. Assuming a similar amount of data was deleted/overwritten since, that would add up to 76GiB. If there’s perhaps one or two more snapshots, that would explain the rest.

Snapshots are “free” only so long as you don’t write or delete any data in the origin.

Atemu , 5 months ago to asklemmy in Do I have Burnout?

I was in a similar situation as you. I pulled through and let me tell you: It did not get better :(

I managed to get good grades and such because I knew most of the core concepts already and had some luck in the intelligence lottery w.r.t the specific kinds of intelligence beneficial in my field which enabled me to learn the new parts really quite easily but if that’s not the case for you, YMMV.

If I was doing it again, I’d stop if possible (a degree was not strictly required in my situation but beneficial). Failing that, I’d find a way to make it not as stressful (i.e. fewer classes).

I do like the idea of using USB drives for storage, though…

I wholeheartedly don’t.

Atemu , 5 months ago to selfhosted in What Router can you recommend?

They are quite solid but be aware that the web UI is dog slow and the menus weirdly designed.
