| I wouldn't call it a "lost art". Author says: "One of the skills I wish I'd learned earlier in my career is basic Linux server administration". There are plenty of books around. And there are literally thousands of people worldwide practicing this "lost" art daily. Starting from small corp up to the major cloud providers. (Someone has to support those computers, running the "serverless" things") My word of advice: start with the "philosophy". One program doing only one task but extremely well, "everything is a file" etc. Understand why people are unhappy with SystemD. :-)
Find out how kernel schedulers impact databases' IO.
Write a boring program in C - network server which forks on accept4.
Tip your toe in Perl 5 - there is lots of it in *nix and BSD. Still most stable and efficient way of writing CGI script ...
Find out why Ksh is faster than Bash. It is truly exciting world, and the best news is that it "fits" as a glove the modern world of JS and async programming etc. I wouldn't call it "lost" - it is just dozen of levels of abstractions down, efficient, boring and complex. But powerful and unforgiving to typos :-) I am glad someone actually is reading about all that. |
