Old Linux kernel security bug bites

OK, hands up, who knows what High-Level Data Link Control (HDLC) is? It’s an archaic networking data framing protocol that’s used in modems, X.25, frame-relay, ISDN, and other now uncommon networking technologies. I know it because I used to work with them back in the day. You’ll get to know it now because a researcher discovered a security hole hidden within the Linux kernel driver that implements it.

Shut up already! How to turn off unwanted web page sound

Are you sick and tired of opening a new web page and being greeted by a loud, obnoxious advertisement? I sure am. Pop-up and pop-under ads were bad enough, but now it seems like I can hardly go to a site without having a video start up with a blaring voice braying about a great diet, deal, or the like.

Canonical extends Ubuntu 12.04 support for paying customers

I was bemused recently when I wrote a story about essential Linux server commands only to have people complain about my covering older init and run-level technology instead of the controversial but popular systemd. This newer way of booting Linux systems became popular in 2015. Unfortunately, some readers fail to understand that a feature that’s been deployed for two years means nothing for server operating system lifespans.

Take, for example, the five-year-old Ubuntu 12.04. Canonical, Ubuntu’s parent company, has just announced that this version of Ubuntu will be given extended security support.
