3 Easy Steps to SSL Client Authentication

There are many resources on the Internet for correctly securing apache web sites with X.509 client certificate authentication. This isn't one of them. What follows is a three step guide to the fastest, easiest method for setting up self-signed server and client certificates. You are advised not to run any of the commands below in a production environment, they are presented only as an aid for those who learn kinesthetically.
A good solution applied with vigor now is better than a perfect solution applied ten minutes later.

A Practical View of Comcast vs FCC

One thing to note about the United States Court of Appeals for the District of Columbia Circuit decision in Comcast vs. F.C.C.-- it doesn't restrict the F.C.C.'s ability to regulate Internet services; rather, the court ruled that the broad regulatory powers enjoyed by the F.C.C. were overstepped when they told Comcast to stop discriminating against BitTorrent traffic . Many individuals dismiss this as a "bad decision" of the court, but to do so ignores important issues relevant to this ruling.

I generally favor 'net neutrality, and I certainly don't take a kindly view of the arbitrary packet discrimination employed by unscrupulous companies; left unchecked, such practices easily (perhaps inevitably) lead to "the pseudo service scenario of bribery ... extortion", but the same slippery slope analogy could slide the other way. Had the appellate court ruled in favor of the F.C.C. it would have set a precedent for allowing a regulatory authority to essentially invent new powers not specifically delegated to it by any act of Congress. If you would prefer that Congress pass such a law, you may wish to ask your representatives to support H.R. 3458.

Automount USB drives on Ubuntu servers.

In most cases, Ubuntu desktop systems will automatically detect and mount removable media, and this is largely done with software that is part of the X Windows system; for server systems without X Windows however, this sort of thing requires a bit of work.

Now some may ask, "Why automount removable media at all?" It is unwise to remove an active device, such as unplugging a USB drive without first unmounting it, and automounting may encourage this sort of recklessness. I don't contend this, but if one runs a server using an external USB drive, there are two words which should spark an immediate interest in automatic mounts: power failure.

Diagnosing Sound Problems in Ubuntu Linux

Sound problems fall in to three basic categories, and the first thing you want to do is determine which one you're dealing with. The easiest thing you can do is test your speakers with something else, using the same cable. If your speakers and cable are confirmed to be in good working order, then the problem must be either:
