I Am, Therefore I Think. Congress shall make no law… abridging the freedom of speech, or of the press…. The Full X11 Palette. August 11, 2014 / gus3. Intel Finally Slims Down. I know it’s been, oh, over a year since my last post. It’s been kind of like the Olympic gold medalist’s let-down:. What do I do now? I’ve done a lot of tinkering, and “what happens if I do this? 8221; kind of stuff, but nothing really big. But this afternoon, I read about Intel’s new 14-nanometer process.

I Am, Therefore I Think. Congress shall make no law… abridging the freedom of speech, or of the press…. The Full X11 Palette. March 18, 2013 / gus3. One axiom of computing is to script commonly-used command sequences, akin to C’s functions, Pascal’s procedures, and Ada’s subprograms. But what if the command sequence involves “su” for elevated privileges? I found an idiom that Works For Me. This example will pull pages from the swap space back into RAM:. Examining syslog timestamps →. Su -c "swapon -a".
