Linux Photography: Basic Darktable Tutorial
I know why my first few minutes with Darktable seemed so frustrating–they were all me scrubbing this modal interface looking for things I thought all should be in a menubar.

Backups: one quick file backup alias
When you have a file you need to edit and you have the foresight to think, “whoa, make a copy before I destroy…” you often copy hulk.txt to hulk.txt.old (that’s using the minimum of keystrokes: cp hul[tab][tab] hul[tab][tab].old[enter].

The build directories that Netbeans uses are pounded a lot, and chances are you have enough ram to leverage tmpfs. Let do it! Start with our /etc/rc.local file: echo deadline > /sys/block/sda/queue/scheduler echo 1 > /sys/block/sda/queue/iosched/fifo_batch D=/home/jreynolds/.cache/netbeans rm -rf $D/* mount $D chown -R jreynolds:jreynolds $D D=/home/jreynolds/NetBeansProjects/MyProject/build rm -rf $D/* mount $D # dont furgit…

Upcoming: New Standing Workstation
I’ve posted about how my previous endeavors to work at a standing workspace, at work, and at home. It has not gone sour on me yet.
