Okay, here's a more or less complete list of the links I visit on a regular (read: at least once a day) basis. I've included some comments about the site as well, in most cases.
I tend to read a lot of Linux and tech oriented news sites.
Slashdot is a regular staple of my news diet. While the comments tend to be low in the signal to noise ratio, occasionally something interesting comes around.
The Register is a UK based tech news website, that doesn't hold back from being critical of things. Not really critical enough IMHO tho, but a good start. Budding Sysadmins will definently want to read the Bastard Operator from Hell series. I'd make it part of COSC1235 if I had the power :).
Dans Data. This Australian reviews hardware and other assorted stuff. He really doesn't hold back if something doesn't make sense. Likes busting myths and misconceptions, and laughing at fraudulent material. Recommended good reading.
Groklaw, a site run by Pamela Jones, who is a paralegal, chronicling the saga between SCO and IBM (which, if SCO would have you believe, is about Linux. It stopped being about Linux ages ago. SCO are tools, in my opinion. Ignore their frivolous lawsuit.) Good reading, particularly because it's not couched in assumptions by laypeople.
Kernel Traffic is a weekly (well, should be) summary of the traffic on the linux kernel mailing list. The LKML gets up to 3000 messages or more a week. These people try to summarize the important bits. Unfortunately, they're falling behind atm :(.
Kernel Trap is a discussion site about kernel development in general. Covers linux, OpenBSD, FreeBSD and related tools.
Planet Eclipse is a blog tracker watching the various blogs of developers of Eclipse. Eclipse is easily the best java IDE you can find, and is also a fantastic Rich Client Platform (RCP), for developing your own applications upon.
If you work too hard, you'll go nuts. Go to shafted and play some games. Take your PC. It's a good way to waste a weekend.
Linux Games. There's a lot of interesting free games for linux, plus commercial ones come out every now and then. This site keeps track of them.
Blue's News, a general gaming site. Has less useless HTML than most sites, which is nice. Ads are getting in the way more and more tho, still, handy to keep track of gaming in general.
Icculus.org. The guy who maintains this site, Ryan 'icculus' Gordon ports games to linux and MacOS X. He rules. He also lets opensource projects get hosted on his site. Which also rules. Did i mention the ruling part? He also has his .plan, which is good reading, since he often has intelligent stuff to say.
Web comics are important to me. Everyone needs laughter.
Sluggy addictive reading. Has a bunch of people getting into bizarre trouble.
User Friendly more addictive reading. Has a Dust Puppy.
Goats is bizarre and entertaining. Has two guys, a goat with panties of potency, a satantic chicken, and other assorted characters. Hilarious hijinks ensue. Not related to goatse in any way.
MegaTokyo is the trials and tribulations of two guys effectively stuck in tokyo. Manga style.
PVP Online is about a gaming mag company. The author also has good rants about stuff.
Real Life. Not as real as it claims, but still entertaining.
GPF Comics. The characters in here have been heading towards disaster for so long it's not funny. Still a good comic tho.
Sinfest. A sex obsessed kid, a skanky jailbait teen, god, the devil, and other characters. Fun. Surprisingly, not explicit.
Sexy Losers. I'll get in trouble for this link, So I won't tell you what's in it. It's definently not work safe, but I don't think you can really call it porn. It's just explicit.
Cat and Girl Weekly statements about the futility of life. The cat drinks paint.
Ctrl-Alt-Del Online Apparently windows users are tools, capable of creating robots out of xboxes. Or something. Entertaining nevertheless.
Diesel Sweeties. Better than a vibrator.
Errant Story Has elves and magic. 'nuff said. Current creation of the guy who wrote exploitation now, which has finished, but is still up.
I'll toss other links here eventually.
Rockbox. They create an opensource mp3 player firmware for the mp3 player I use (An IRiver H140), as well as the archos players. They rock.
