Last Updated: September 29th, 2016 at 3:38 pm Paul Anderson

Review By Paul Anderson / September 29, 2016 — Web

It is possible to put background text on the frame of Chrome by creating a custom extension. Generally, I’m pretty conservative about browser themes, because too much noise makes it difficult to scan a page. The web is noisy enough as it is. I have a need to constantly look up some information that id […]

OpenBSD 2.9

Last Updated: May 11th, 2018 - Paul Anderson

By Paul Anderson / May 11, 2018 — BSD

BSD is often a good choice for utility boxes running stuff like Sendmail or BIND. The hardware support isn’t as good, and if you think desktop applications are bad with Linux, then you certainly aren’t going to like BSD. BSD is arguably more secure and stable than Linux. In the gradient of stability, though, Linux […]
