This Github repo has every issue. Lots of info it's outated, but stuff on FVWM, TWM, scripting, sh, sed, awk, Perl... will just work.
Some of the information is out-dated yes, you'd expect that. Especially when people were asking for help about dial-up modems, for example.
But I bet if you were to try some of the other stuff on there, it would still work today...
