Windows 10: Multiple displays

I use my 23″ monitor as the main display when paired with my 14″ Windows laptop (HP EliteBook 840 G3). 150% display scaling is fine with 23″ of glorious, screen real estate, but eye-achingly small on just 14″; i.e., when I go for meetings.

I was trying to compile collectd on a old CentOS 6 host, and ./configure complained that rrdtool couldn’t be found; e.g. rrdtool . . . . . . . no (rrd.h not found) I’d intended to use rrdtool to collect instance-level metrics and then graph ’em out with CGP, so it was pretty annoying. TIL that […]
