  1. No fundamental difference.

  2. Machines, that is to say interpreters of machine language, can be built out of software as well as hardware.

  3.  @Spartan322  A “machine language” is anything understood by an appropriate “machine”.

  4.  @Spartan322  You’re not saying anything different from me. Particularly when you realize that “machine” doesn’t have to mean “hardware”.

  5.  @Spartan322  On the contrary, such a unification is incredibly useful. As you go into later CS courses, you will discover this.

  6.  @Caellyan  Why do non-CS people get so angry about this? It’s well-known that the distinction between “hardware” and “software” is pretty vague at the best of times -- if you insist on building a wall, think of concepts like “microcode” and “firmware” and where they fit in.

  7. Having done one or two sysinit scripts and systemd service files, I find systemd easier.

  8. You must have “shopt histverify” set.

  9. I don’t understand how this anti-systemd nonsense is able to proliferate. The code is out there, go look at it for yourself. If you find bugs, why not fix them? Go talk to admins and distro maintainers who are adopting it. They are embracing it because it solves real problems. Nobody is holding a gun to their heads. This is the Free Software world, after all! No company can own it. And of course, if you don’t want to use it, there are still a few distros around to cater to that preference, too. If that’s not enough for you, feel free to do what their maintainers did, and create your own!

  10. No, the “size on disk” would include whole space units that are allocated to the file, even if only part of the last one is used. The “-s” option in the ls command shows the allocated size. For example, see this listing: ldo@theon:github.com∕imageio> ls -ls imageio-ffmpeg/imageio_ffmpeg/ total 48 4 drwxr-xr-x 2 ldo users 4096 Jan 12 21:49 binaries 4 rw-r--r- 1 ldo users 1420 Jan 12 21:49 _definitions.py 4 rw-r--r- 1 ldo users 227 Jan 12 21:49 __init__.py 24 rw-r--r- 1 ldo users 21515 Jan 12 21:49 _io.py 8 rw-r--r- 1 ldo users 5870 Jan 12 21:49 _parsing.py 4 rw-r--r- 1 ldo users 3085 Jan 12 21:49 _utils.py You can tell from there that the filesystem is allocating space in units of 4096 bytes.

  11. WordPress is not exactly known for its speed though, is it.

  12. I ran it for a while. Every time I went to do an update, the first thing it would say was “a new version of portage is available”, and you should upgrade that first.

  13. Use a GUI frontend if you can’t handle the command line. For example, gnome-boxes.

  14. The only sudo command I use is “sudo /bin/bash”. Or, for extra coolness (saving an extra CTRL-D to exit), how about “exec sudo /bin/bash”.

  15. There are less than a dozen BSD variants, versus hundreds of Linux distros. Yet all those Linux distros are more easily interoperable than those BSDs. One of those ecosystems offers true “variety of choice”, while the other is hobbled by “fragmentation”.

  16. 0:44 I don’t allow food and drink near my computers. So that avoids that problem.
