By the time you're 35, you should have successfully done following at least once:
1. rm -rf / on your unix or linux box
2. Reboot production server by mistake
3. Drop CPU/hard disk and damage it permanently
4. Changing firewall rule instantly blocked you out
5. No backup was made/verified ever...
6. Delete source code before actually committing to source control
7. Run a SQL update/delete with wrong where clause

My first intentional rm -rf / was a complete disaster.
I set up a VM, just to see the chaos first hand. Various things breaking. See how long Linux could just keep running.
... I did not realise that the particular VM had automounted my root drive.

@nixCraft I didn't get root privileges on a Unix (like) box until I was about 35, so it took me a little while to catch up.
There are a couple of those I've done (again) within just the few months.

@nixCraft Also 8. Wearing a thick polyester (? - well, not cotton anyway) long sleeve, I came close to a physically open but running computer we were putting together at the office ... did not touch ... a long spark. The system stopped.

@nixCraft isn't 6 what we do every 6 months?

@nixCraft * without a Where clause
Does this count ?

DOS yourself, by setting the notify rules wrong.

@nixCraft yes to all.
5 for me on verified.
Lessons learned.

1-no
2-who hasn't?
3-no, the sh*t was too expensive
4-no, i always double check
5-erm... yes
6-no, i always keep backups
7-only on personal projects
Worst case i can remember was when installing a service pack and the server threw a "file not found" after reboot. Had to try the service pack 5 more times after recovery. The reason was that the RAID controller was not battery backed and it rebooted before the data was successfully written to the disk.

@nixCraft "35"? Oh, my sweet summer child.

@nixCraft How not to delete a debootstrap installation:
root@some.computer> rm -rf . /*
Notice the accidental space between . and / ? I didn't.
It got through /bin, and was complaining it couldn't delete devfs on /dev, before I killed it. I hadn't lost /home, but I did have to reinstall from disc.

@nixCraft I've locked myself out of a server after changing firewall rules more times than I can count.
Michael
@nixCraft The only one I am missing is number 6 because I can't commit when I'm not using source control in the first place!

@nixCraft seems im late to the party

@nixCraft 7/7 I feel like I real Sr. Admin now.
Twirrim
@nixCraft no, yes, no, yes, no, no, no.
I keep feeling like I'm the only sysadmin who's never rm - rf'd root. Came real close, a second bug in a cron script I wrote caused the first bug that'd have done it, to not fire.
Stephan
@nixCraft as long as you already added your code to the source control, you may be able to recover it - at least in git.

@nixCraft Was thinking who makes those sort of mistakes. Then I got to #7, ooops, when I was a novice I did that one.
Elías Chao
@nixCraft I once updated a database in the wrong server, does that count?

@nixCraft I haven’t done the firewall one, but I have applied a Windows Group Policy that locked me out of the management tools so I couldn’t fix it!
Kirk
@nixCraft
By the time I was 35 I had done most of those things but my favorite was rm -rf ing the Jenkins box because I was fighting with it. That felt soooo good and was totally worth spending the rest of the day restoring backups I didn't know we had

@nixCraft 1. on purpose to test, 3 .. nope sorry .. that never happened .. , yes on all the others ..
