Cerebro, a Spotlight-like launcher for Linux

I recently “made the switch” from MacOS to Linux Mint, and was lamenting the fact that I didn’t have Alfred on Mint. But then this morning I learned about Cerebro, which, if it’s not Alfred yet, at least it’s Spotlight for Linux. omgubuntu.co.uk has this good intro article on Cerebro.

When tuning a server, you'll really want to tweak for performance and high throughput. That's where most Linux configurations really shine over the competition: they come better tuned to get the most out of server configurations.

How to type smart quotes on Ubuntu Linux

There seem to be a few different ways to type “smart quotes” on Ubuntu Linux, including using keys (keystrokes) like AltGr and Compose. In this tutorial I’ll document an approach that works best for me: creating simple macros I can assign to simple keystrokes rather than having to use more-complicated keystrokes.

An Ubuntu screensaver shell script to rotate images

This is a Bash shell script written for Ubuntu (Linux). I just switched from Mac/MacOS to Ubuntu, and I don't like the default blank screensaver in Ubuntu. I just want a screensaver to rotate my collection of images, so I'm considering using this rather than Xscreensaver. The script comes from jamcnaughton.com.
