One. Two. Test, test. (Is this thing actually plugged in?) “We begin bombing in five minutes.” Ok, so now I’ve got myself a blog. Not that I’ve got any idea on how this whole “blogosphere” thing is supposed to work, but I’ll figure it out. text/html 2018-09-10T14:21:36+00:00 Anonymous (anonymous@undisclosed.example.com) https://rootdirectory.de/doku.php?id=negix:negix&rev=1536589296&do=diff "Negix"? You might wonder about the name of this Blog, “Negix - Things not POSIX”. Let me shed some light on this. Back in its time, Unix was a powerful operating system, which brought many signifcant advances to the field of operating systems. The one major shortcoming of Unix was that it didn’t take a bow and itself off the stage when it was time to do so (which, text/html 2018-09-10T14:21:36+00:00 Anonymous (anonymous@undisclosed.example.com) https://rootdirectory.de/doku.php?id=negix:ohplease&rev=1536589296&do=diff Oh please, for the love of the gods... For those short of attention span: Know what you are doing, use what is offered to you. Crontabs are a powerful feature of Unix operating systems. With a simple command and a line of text, you can set up a command to run repeatedly, at very precisely specified intervalls, to do your bidding. text/html 2018-09-10T14:21:36+00:00 Anonymous (anonymous@undisclosed.example.com) https://rootdirectory.de/doku.php?id=negix:painisntalwaysincode&rev=1536589296&do=diff Pain isn't always in code “Sciatic pain syndrome”.

I should have known I wouldn’t find the time and patience to do this, either… And when there was a thread at OSDev: What’s free? BSD vs. GPL, I found I had summarized many of my feelings in one single, if not that eloquent, post. The flame to answer the question of life, the universe, and everything.
