I just started checking out auditd and made a rule to log file accesses.

auditctl -a always,exit -F dir=/path/to/my/directory -F perm=rwa

From the output, I got some things that might be useful:

• The full path of the executable
• pid
• Parent's pid: ppid
• Process' current working directory cwd

Now if the process was still running when I check the logs, I could open htop and find out what exactly called the process, from the pid.
For example, say I run a git pull on a repository and find out that /usr/bin/ssh is accessing some file, I will get something like:

st
└ bash
    └ git
        └ ssh

I will get the full executable path of each executable (and know if the executable was not in the system directories, but in some unsafe location writeable by another user). This will give me enough context to go by.

But using this same example, what happens if I check the logs after the git operation has ended?
The git process ppid will have been lost(?) and I would have no way to know which process called ssh.

How do I solve this condition?
Ideally, I want to have the audit log contain the whole calling tree with the full executable path of each parent.

Title

ffmpeg ... -c:a flac -exact_rice_parameters 1 -multi_dim_quant 1 ...

I was encoding wav to flac.

• With default options, the result was almost instant
  • At > 500x speed
• Used -compression_level 12, finished in ~ 7 seconds
  • speed = 48.9x
• Then I used multi_dim_quant
  • After ~ 10 minutes, I checked the speed to be ~ 0.02x. So thought it would take an hour or so. 1.30 seconds worth of audio was encoded
  • It's been over 2 hours now.
    • Shows 1.46 seconds of audio encoded with current speed = 0.00017x

Considering running it in a VM, so I can "pause" it whenever I need to restart my computer.

Update:
size= 123KiB time=00:00:02.82 bitrate= 356.3kbits/s speed=4.68e-05x
It stopped trying to use layman notation.
I'll need to restart soon-ish, but I'll see how far this goes and if the 2.82 seconds of audio is even listenable.

Also, bought 2 of them, because the brain needed to fart out loud.

Not only are the fans much slower than what the sticker says (2000RPM), they also make more heat in the motor than they will ever dissipate. And of course, they just couldn't sell one without RGB.

Looked closely and even the axle is not centred.

On the other hand

Can someone help me do something fun with this that would make me feel less shitty about myself?

Screen Recording of an application window: at the bottom of a widget, the cursor changes to a resize icon. Click+Dragging the portion reveals empty white space.

Description, because "alt text" can't show it well:

			{
				emit differentFiles (ckFile.absoluteFilePath(),
					otherFile.absoluteFilePath(),
					FileCompareWorker::FileComparisonParams{FileComparisonParams::FileNameMatch,
						(ckFile.size() > otherFile.size()) ? FileComparisonParams::File1IsLarger
							: FileComparisonParams::File2IsLarger});
			}

After Alignment

			{
				emit differentFiles (ckFile.absoluteFilePath(),
					otherFile.absoluteFilePath(),
					FileCompareWorker::FileComparisonParams{FileComparisonParams::FileNameMatch,
						(ckFile.size() > otherFile.size()) ? FileComparisonParams::File1IsLarger
														   : FileComparisonParams::File2IsLarger});
			}

Do you reduce your router's WiFi Transmit Power to the bare minimum as required by you?

• Do you just keep it at the default 100%
• Did you not know you could reduce it (until now)
• Are you not able to control "your" WiFi router because it's the ISP provided router and they didn't give you the password?
• Do you actually require the 100% !?

A person, on the Gnome Issue, suggested that terminals inhibit sleep when there is stuff running in them.

Continuing from that discussion, I am trying to understand, at which point it would be desirable to implement said inhibition - terminal emulator, the shell or the program itself

Additionally:

• We want to inhibit when running stuff like pacman, wget, cp or mv
• We don't want to inhibit when running stuff like htop, less, watch

Hopefully we can get better input to the discussion here.
