From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

it's not always sunny with podman (lemmy.ml)

I am moving from docker to podman and selinux because I thought that podman is more secure and hence, the future. I thought the transition will be somewhat seamless. I even prepaired containers but once I migrated I still ran into issues.

minor issue: it's podman-compose instead of podman compose. The hyphen feels like a step back because we moved from docker-compose to docker compose. But thT's not a real issue.

podman does not autostart containers after boot. You have to manually start them, or write a start script. Or create a systemd unit for each of them.

Spinning up fresh services works most of the time but using old services that worked great with docker are a pain. I am wasting minutes after minutes because I struggle with permissions and other weird issues.

podman can't use lower number ports such that you have to map the ports outside of the machine and forward them properly.

Documentation and tutorials are "all" for docker. Github issues are "all" for docker. There isn't a lot of information floating around.

I'm still not done and I really wonder why I should move forward and not go back to docker. Painful experience so far. https://linuxhandbook.com/docker-vs-podman/ and following pages helped me a lot to get rid of my frustration with podman.

Regarding the low port number thing, that’s just a consequence of not running as root. By default, regular users can’t listen on ports below 1000.

You are correct. I’m as bad as hard drive manufacturers.

Well hard drive manufacturers are actually correct. A gigabyte (GB) is in base 10 and thus 1000 megabytes, not 1024. Gibibytes (GiB) are base 2 (hence “bi”) and thus 1024 mebibytes.

I know it's technically correct but it still hurts a little inside to admit it each time.

I know the reason is because giga is an SI prefix but all the way through my education, 1 GB was taught to be 1024 MB, so I always want to use this instead of what is correct.

To be fair, the tech industry has been naughty with things like this. I know of two. I wonder how many others there are?

I believe that:

The style of characters a user can choose is called a typeface. I think every piece of software calls it a font. I remember hearing it came from Apple/Steve Jobs.
I believe the use of setup is incorrect. Setup is a noun, so it refers to an existing configuration. It tends to be used when running an OS or program for the first time though, which I believe set up is the correct term. Set up is an adjective and refers to the act of creating the configuration.

I've wondered if these were done due to screen space constraints or aesthetics.
