2. Be civil
- Understand the difference between a joke and an insult.
- Do not harrass or attack users for any reason. This includes using blanket terms, like "every user of thing".
- Don't get baited into back-and-forth insults. We are not animals.
- Leave remarks of "peasantry" to the PCMR community. If you dislike an OS/service/application, attack the thing you dislike, not the individuals who use it. Some people may not have a choice.
- Bigotry of any kind will not be tolerated. This is an LGBTQ+-friendly community -- if that is a problem for you, you should leave.
3. Post Linux-related content
- Including Unix and BSD.
- Non-Linux content is acceptable as long as it makes a reference to Linux. For example, the poorly made mockery of
sudoin Windows. - No porn, no politics, no trolling or ragebaiting.
- Don't come looking for advice, this is not the right community.
4. No recent reposts
- Everybody uses Arch btw, can't quit Vim, <loves / tolerates / hates> systemd, and wants to interject for a moment. You can stop now.

6. (NEW!) Regarding public figures
We all have our opinions, and certain public figures can be divisive. Keep in mind that this is a community for memes and light-hearted fun, not for airing grievances or leveling accusations. - Keep discussions polite and free of disparagement.

They call it disk destroyer for a reason. You gotta alias that shit.
alias dd='echo Did you triple check which device you picked? Of course not, dipshit. Check again'There's nothing specially destructive about
dd. It's just a program that opens a file, and if you tell it to open a device file and it's got permission to write to it, it'll write to it.You can just as easily overwrite a disk's contents with anything else that will open a file and write to it.
will wipe your drive with random data in the same way that
will.
You're technically right, but the way most people use dd ensures its like handling a loaded gun. How often do you cp /dev/sdwhy?
Hahahahah I need to do that lmao!!!
Surely double checked is enough
It's not. Neither is triple checking. Notice how the alias doesn't actually run
dd? That's on purpose.I quadruple check and then I still don't run it because I'm too nervous so I go and do something else instead and the item remains buried on my to-do list indefinitely.
Lol, as someone who tried a bunch of different distros, I used the dd command a lot without ever realizing what could go wrong with it. I must have used up all my luck with that though, because somehow I ended up on manjaro of all things.
