Arbitrary Milestones

Scott Lowe’s post this morning echos something I learned a few weeks ago myself: Windows 2008 Server was released as SP1. And I had the same thought as him: WTF. For this we have to thank all of those organizations that have chosen arbitrary releases as the first time they’ll touch new software. From operating systems to disk array firmware, it seems that a lot of system administrators will only start looking at a new version once it’s had a service pack or patch set released for it. And as a result we now have software vendors gaming the system by releasing first versions as SP1. I’d like to share with you all a little secret: all software has bugs. …

How File Deletions Work

Q: I deleted a bunch of files from one of my virtual machines yesterday. Deduplication happened overnight, but the total disk space in use didn’t go down. That doesn’t make any sense. Q: I completely evacuated one of the LUNs on my NetApp array, but the NetApp still says that the LUN is almost completely full, even after deduplication. How can that be? A: To understand what is happening you need to know a little bit about how a file system works. A simple way to explain it is that a file system stores the data in a file as data blocks, and it stores the name of the file (and other data, like access times, etc.) in a directory …

Expectations

“When do you think our servers will ship?” That’s always the warning shot, fired over my bow. My customer didn’t tell me something, and weeks later they finally got around to listening to me. Now they don’t like something I had to say, after they agreed to all of it. “If you refer to the timeline I gave you several weeks ago your physical servers will be ready in two more months,” I reply. I always tell customers that it takes at least three months to acquire physical hardware. Two weeks to figure out what to order, by gathering facts, performance data, and sizing information. Two weeks to actually get it through their purchasing people. Four weeks to receive it …

Almost 1234567890

OMFG, if it hadn’t been for my friend Maitri I would have completely missed the UNIX timestamp becoming 1234567890. It isn’t too late, though, to script a recursive: perl -e ‘print time(),”n”‘ and witness computing history. ๐Ÿ™‚ That’s a lot of seconds since midnight on January 1, 1970.

Will Law – Blog ยป How to install SBC/ATT Yahoo DSL without the install CD in 5 easy steps This guy is my savior. It's been a three week saga to get DSL working at home again after a billing snafu got it disconnected, just to be foiled by some idiot tech who insists I need the setup CD. I don't need the CD, I just need my account set up, but he didn't want to do that with me. AT&T sucks.

My blog, as seen through Wordle. Click on it to see a larger version. Visualization tools are neat ways to spur new and different thoughts about things. Or point out that I, like, totally sound like a valley girl sometimes. Like like like.

The Bacon Explosion – Take Bacon. Add Sausage. Blog. – NYTimes.com A friend made this for the Super Bowl, I need to find out how it went. I wonder if it'd work in a slow cooker… grilling in mid-winter is sorta cold. Targeted nanospheres find, penetrate, then fuel burning of melanoma | Science Blog "Hollow gold nanospheres equipped with a targeting peptide find melanoma cells, penetrate them deeply, and then cook the tumor when bathed with near-infrared light." Anthropomorphizing the nanospheres by saying that they 'find' melanoma is ridiculous, and is the sort of inaccuracy that contributes to the decline of our general science knowledge. This isn't some weird version of the movie Innerspace, they just created a compound that …

Super Bowl XLIII

1. I fell asleep with about four minutes left in the first quarter, which just reinforced my suspicions that in good football games the first three quarters only set the stage for an amazing fourth quarter. 2. I didn’t see most of the commercials, but of the ones I did see the Doritos crystal ball one was my favorite. If you didn’t see it, it’s a guy telling a skeptical coworker that his crystal ball (a snow globe) says there will be free Doritos at the office today. He then turns and throws it through the front window of a vending machine. Heh.

Mask? Check. Costume? Check.
