How to upgrade Ubuntu 14.10 kernel to version 3.17.1

Upgrading a distribution’s kernel is something I tend to shy away from. There was a time, though, when recompiling the Linux kernel was fun. But that was years ago.

Use Tor Browser, get your computer blacklisted

Use Tor Browser, get your computer blacklisted

For the past few years I’ve been using a URL shortening service called ur1. It is a GPL-licensed URL shorterner from StatusNet Inc..

With Btrfs the default on openSUSE, when will other distros follow suit

With Btrfs the default on openSUSE, when will other distros follow suit

One change that was implemented in openSUSE 13.2 makes Btrfs the default file system for the root (main) partition.
