@Fabby nice :D

co-workers once made a backup on a friday of software we adjusted the past week. 3 people where at it for 10 hours 4 days. he deleted the backup and the rest of the directory by adding a space to the rm.

he got seriously lucky... one of the employees had to go early that friday and he was reasponsible for the backups. The backup was done minutes, if not seconds, before he did the rm :D

so we wasted another 4 hours waiting for the restore :X HE paid for diner on the way home :+)

I switched from Windows to Linux on my HP laptop.

With certain networks like the one at my home, I can connect, but the connection is very ...

Q: The StackExchange website keeps me logged in between sessions without asking me

The login screen for StackExchange/AskUbuntu has no option to select or deselect a "keep me logged in" function, but it retains the login by default. Retaining an everlasting login session without the user's permission has got to be some kind of bug or design flaw. The security implications are...

Good day

Is it possible to add new user with password in one line? I did hope, that `useradd hello -p world` would work, but then I found the note, that "*The encrypted password, as returned by crypt(3).*"
Asking because I want to add one more user within Dockerfile instead of default provided root user.

On 18.04 in the normal repositories there is a package called python3-exif which is great because I want to parse EXIF with Python.
But how to find documentation for it? There are so many different EXIF parsing Python libraries, I can't figure out which one is in that package.
Thanks!

@NicolasRaoul the package contains a file called /usr/share/doc/python3-exif/examples/EXIF.py, maybe that’s helpful?

@NicolasRaoul also there’s /usr/lib/python3/dist-packages/ExifRead-2.1.2.egg-info/PKG-INFO, which may contain package info ;P

In Ubuntu 14 I have a bunch of SysV init scripts (/etc/init.d/). After migration to Ubuntu 16 they do not really work, as I understand Ubuntu 16 generates systemd unit files on the fly. Some services can be started but some not. My idea is to: relocate SysV init scripts (/etc/init.d/ -> /var...

@Rinzwind Yeah! :)

@Rinzwind Really lucky!

I wasn't: we lost 1 or 2h of work but had to restore 1 full backup and 2 or 3 incrementals. (=1 entire day lost)

(we started doing differentials soon after)

Q: Ubuntu 18.04.1 LTS keyboard is disabled tried standard solutions already

2:22 PM

@Fabby we've all had misclicks/bunged up commands. I keep 2 trees of all code for that reason. Meant to delete something - deleted something else critical. Copied it back from tree 2. You fat finger something from time to time. It happens. As long as you're prepared for it, it's no big deal.

2:32 PM

I got backups of backups of backups of backups. Heck we use google instances and every instance does a real time copy to another google instance as a fallback + an amazon real time copy as fallback 2 + our chinese also does this to alibaba. And each of those has a real time backup with incremental change log. Then we make manual copies each friday. Plus I have my own personal copies D:

Okay, so this is what happened. I came home and noticed my kids had tried to log on my laptop when I was at work. A massive keystroke password was there. However, I found that I when I restarted the computer I couldn't use the keyboard at all. I was able to use Accessible onscreen keyboard ...

I'd make the kids fix it and give them only water and bread until they do.

@cl-netbox I've told all customers and the boss already for months I did have a day off.

@Rinzwind To be completely honest: I was sitting next to the guy who typed it.

He asked me to verify his commands.

I still had to do the restore though.

(So that's why my spine turned cold)

@dessert lubuntu.net is also not the official Lubuntu site anymore.

@Rinzwind Starred!

@RobotHumans I lost all my 80-90s source code when I migrated to precise.

No big deal: who's ever going to ask for the PASCAL source code of anything I ever developed?

Even customers: I had to help a customer back in the early 2000s to extend his license key.

(for an ex-employer)

I remembered the algorithm we came up with and where it was stored (Windows Registry in the help section and it was a julian date XOR A) so I extended their licence to 1/1/3000.

Their data was important and the ability to run their program...

Even had to once reverse-engineer a Windows accountancy program I knew nothing about to copy it from one machine to another: 4h of work manually copying registry keys and DLL files.

Long live Linux: You have access to all the source code forever

Isn't the star wall in this room nice?

What is the recommended raster graphics editor for GNU/Linux, that is not as convoluted as GIMP and also has a nice UI?

raster editing/unlimited resolution is inkskape, but not as convoluted has nothing to do with it.

spillthrill

10:54 PM

I thought Inkscape was for vector, not raster. Something like MS Paint, Paint.NET, Paint 3D on Windows 10, etc. Maybe "convoluted" wasn't the right word; it's just that I don't need anything as involved as GIMP. I want something simpler like MS Paint.
