apropos man posted:Bingo! Although I haven't got a clue how the syntax works here. When I see a regex I want to use I usually copy and paste and think "I dunno how it works, but it works". Cheers! The regex is whatever is between the / marks, which in this case is just the string "magnet". So not much of a regex  . Then the d at the end means "Delete whatever lines matched this".

evol262 posted:Sure. Set up a docker container with whatever base image you want, add on dependencies (ruby/Python/whatever). Check out the git repo. Install nginx. Start the webserver and export the port. Great! If I can avoid using up the space a full vm would need then I'm all for it.

There's suddenly a lot of bash frameworks floating around. How do they compare to oh-my-zsh or prezto? I really like both of those zsh options, but the performance on each one sucks in a different way.

drat that's eye opening. I had no idea that universe existed. And I'm not sure I like it. I mean I can see the value of making scripting easier, but a major benefit of shell scripts is they have no dependencies. Making a framework a dependency for basic server administration seems like it could be risky.

I really like both of those zsh options, but the performance on each one sucks in a different way. You could always try something like Antigen or ZGen. There's no shortage of zsh configuration managers designed to provide the benefits of OMZ without the performance hit. Although depending on what you use, some performance degradation may be unavoidable; syntax hilighting, for example, is going to noticeably slow things down (especially pasting large amounts of code into the terminal) no matter what you use to load it.

What actually is emacs and is it worth learning? Every time I do some digging all I find is basic editing features and org mode todo lists, but some people talk about it like it's an OS in the OS or some crazy poo poo like that.

My second programming course in university used Scheme language with emacs. As my final exercise of the course I created a Core Wars game with GUI that ran inside emacs. So I guess it is an operating system. It used some XDRAW extension for the graphics that I haven't found any information about and I have no idea what it would require to make it work anymore.

I'm looking at getting a new laptop. Is there anything I need to consider as far as installing linux is concerned? I haven't looked at hardware since I got this in 2011, so I don't know if there are any bad combos of things that would make problems for linux. I apologize if this is the wrong place to ask, but the Laptop megathread seems to be geared toward windows.

Buy something with as many Intel components as possible. HiDPI support still isn't perfect on any hardware, but it's decent. All the major big players make Linux compatible laptops. You can even buy a Dell XPS13 with Linux pre-installed.

I speak from experience when I say absolutely do not get one with AMD switchable graphics if you're planning on actually using the discrete card with Linux.

Usually if the driver you need isn't built in with your kernel you can usually grab it from their site and compile it but it's still super annoying.

This might be a silly question but here goes: one of the computers I'm using has gcc v4.8 with appropriate openmpi and blas libraries. I now need gcc v4.9 to build a newer version of the library I'm using. Do I need to build a new version of openmpi and blas with the new version of gcc or can I just use the existing ones?

I'm going to try my hand at using Linux again, as a hobbyist. I'd like to build a solid foundation of knowledge this time, instead of blindly pasting commands into the terminal. How is the http://www.linuxfromscratch.org regarded? Is it worthwhile reading the book and walking through the steps?

You'll learn very little practical knowledge from doing this. You're much better to pick a project and try and implement it. E.g. work out how to build a simple lamp stack and setup wordpress, set up a file server, learn about virtualisation, provision a stack using configuration management .....

No one builds software anymore, it's all software config these days. If you really insist on getting your hands dirty do one of the more bare installs like arch or slackware or something. Otherwise just pick one of the big ones like Ubuntu or one of the RedHat versions.

Blindly copying things from the LFS/Gentoo documentation or Arch wiki won't really teach you anything either. Do real things, as above. 99% of people have no real need to know the "guts" of Linux to do productive things with it in 2017, including development. Otherwise, install whatever, set up KVM, and put a BSD on (which have great "core" documentation and absolutely no info about how to do much else) a VM, and almost all of it is broadly applicable to the way the "guts" of Linux work. Except you're forced to learn it to do anything.

Theoretically, a source you trust wouldn't do that. Just like you wouldn't expect redhat or debian to put malicious stuff in their signed packages. They could, but you trust them not to. Same goes for a file on a website. As long as you don't have some sort of man-in-the-middle thing going on.
