  1. Imagine waking up from a hangover to find a strange OS on your PC ...

  2. The reason why Debian has so many offshoots, is because it makes it so easy to create those offshoots. All the tools you need to build Debian and its packages come with Debian itself.

  3. 3:13 The key difference between “su” and “sudo”, as far as I’m concerned, is that “su” prompts for the root password, while “sudo” prompts for your password. “su” lets you become any user for which you know the password, not just root. It also allows the root user to become any user without knowing their password. “sudo” gives you more fine-grained control over what users are allowed to do. Many admins prefer it because it doesn’t require the root user to have a valid password. Linux faux pas I see too often: people using sudo to run su. Tisk.

  4. There are quite a few other history substitutions, e.g. “!!” to substitute the last command “!«n»” to substitute command number «n» from your history “!«prefix»” to substitute the last command beginning with “«prefix»” “!?«substr»?” to substitute the last command containing “«substr»”.

  5. So su me.

  6. Debian Stable for servers, Unstable for workstations. I keep my Unstable upgrades down to once a month. Wondering what will break next helps to keep me on my toes. ;)

  8. Just use the “dd” command. It does sector-level copies between volume-image files and actual storage devices. Actually it does other things as well, but that’s a common application.

  9.  @johnstath9666  Just be careful. They don’t nickname it the “data destroyer” for nothing. 😈

  10. I never bothered with awk. I found Perl did everything awk could do and more, and do it just as concisely.

  11. I tried “sudo mkdir ~/limbo”, and it was in my home dir. If sudo executes the command “as would root execute it”, it would be in root’s home dir, not mine. So you must be wrong.

  12.  @omegaman7377  And what makes it so easy?

  13. That group is just one of the ways of controlling access to sudo.

  14. Linux has desktop standards the way the car industry has cars. There are way too many of those, don’t you agree? Different size engines, different numbers of seats and doors, different body shapes, different colours -- they can’t even agree on which wheels should be driven by the engine! What the car vendors need to do is agree on one standard configuration. Otherwise these new-fangled vehicles will never take over from the good old horse and carriage.

  15. System admin functions require privileged access that is not needed while doing normal user tasks. It is best to keep them separated. In particular, never log into a GUI session as the root user.

  16. KDE is for people who want their desktop to look the way they want. There’s a tute somewhere that shows how to make it look like MacOS, if you want. You see, on Linux, the GUI is just another replaceable modular layer, it’s not part of the OS, like it is on those more typical 1990s-era operating systems.

  17. 2:09 Hyper-V is Windows-only, as I recall.

  18. For those who think 26 drive letters ought to be enough for anybody, a new version of FreeDOS just came out recently.

  19. My main clients have (nearly) always used Debian on their servers.

  20. GUIs don’t scale.

  21.  @CallousCoder  There was a survey of the VFX industry released about a year ago. That is 60% Linux now, and set to grow even more.

  22. If you develop for deployment on a platform, then it is wisest to stick with packages that come with that platform. For example, in developing Seaskirt, my Python management wrapper for the Asterisk telephony engine, I was able to run Asterisk 20 on my main workstation. But since the newest version currently available with Debian Stable is Asterisk 16, I was careful to maintain compatibility with that.
