Livingsocial got breached. You need to change your password, if you have a Livingsocial account. There are two questions worth asking: How do you protect yourself, and how does this happen?

Lenovo’s phone is ringing again. And it’s IBM. Again.
When IBM sold its desktop and laptop PC business to Lenovo nine years ago, it held on to its x86-based server business. But now, IBM doesn’t see the x86 server business as a growth area anymore, and now they’re interested in selling that to Lenovo, too.

Exploiting Twitter
It’s interesting that I read two things about buying Twitter publicity today: John C Dvorak’s experiment for PC Magazine and an interview with my classmate and friend Ken. The idea is that people buy Twitter followers to make themselves look bigger than they are, whether they’re celebrities trying to make themselves look like they’re on [...]

And the most security-riddled program of 2012 was….
Secunia released its annual vulnerability review, a study of the 50 most vulnerable pieces of software in 2012. It was a fairly tight-three way race at the top, and the distance between #3 and #4 was huge. I was actually surprised at who the top three were. They weren’t the three usual suspects. But in [...]

Use Apachebench to test your webserver optimizations
If your web server is slow and you want to fix it, it’s nice to be able to quantify what you got. Enter Apachebench, which is part of Apache and probably already on your server.

Home network projects for a budding sysadmin
A very good question came in as a comment to my earlier post, the benefits of practicing IT at home. What do I mean by putting some Windows 7 machines on a domain? I mean standing up a server with centralized user accounts and shares, running on Windows Server or Samba, whichever you can afford. [...]

The benefits of doing IT at home, too
Earlier this week, The Register touted the benefits of having a home lab. That lab doesn’t necessarily have to be elaborate. But there is definitely something to be said for having some equipment that you can learn and experiment on, and that can break without the world ending.

Wi-fi wants to be free… except it’s not 1994 anymore
The Open Wi-Fi movement was on the front page of Slashdot yesterday afternoon. Predictably, comment #2 was, “give me immunity from the MPAA and RIAA and I’ll open my Wi-Fi.” Valid point. Very valid point. Though there are other problems, too.

A minor (but vital) Apache performance tweak
My problems seem to have become more rare since I started blocking spambots and tuned PHP and Apache but last night my server ran out of memory again and started timing out. It turns out I still had a critical problem, but one that’s easy to fix with a relatively simple Perl script.

SSD write endurance (aka longevity) vindicated
I found this chart earlier this week regarding SSD write endurance. Basically, it plots out how long an SSD would last if you set out to deliberately destroy it by writing to it continuously. You could expect a mainstream 128-GB drive to last 4.7 years under those conditions, which is longer than a platter hard [...]
