Kindle vs. Kindle

Kindle 4

So, you might have heard about Amazon's new Kindles. They're kind of a big thing. There's even talk that Jeff Bezos is the New Steve Jobs, which is kind of silly, but serves to underscore the point that Amazon is big news these days. Anyway, you might also remember from an earlier post of mine that I have a Kindle 2. Well, when I saw the new Kindles, I couldn't resist. So now I also have a Kindle 4 (non-touch). It's pretty awesome. Let's start with some sexy comparison shots (flickr set):

The most stunning thing about the new Kindle …

TouchPad!

TouchPad So, I got one of the Internet-legendary $99 TouchPads (well, $149 actually, but whatever). As some of you may know, I was an enormous Palm fanboy during the 90's. So it was pretty inevitable that I would end up purchasing one of their WebOS products, even though there's not a lot in common between this and Jeff Hawkins' wooden cutout Palm Pilot. Anyhow, this is probably going to be the nerdiest review of the TouchPad posted on the Internet. It mostly is concerned with keyboard mappings. Enjoy!

Rawr, Lion

Mac OS X Lion If you've read any kind of tech news in the last few days, you might've noticed that Mac OS X 10.7 Lion is out. I wasn't going to upgrade for a while, but then it launched and I did. So I've been using Lion for a few days now, and I thought I'd join the endless ranks of people on the Internet talking about Apple's latest big cat. I'm not really going to be much competition for the real tech writers, so if you want to learn nearly everything about Lion, I recommend making a pot of tea and sitting down to John Siracusa's latest tome. Otherwise, read on to see what I think of the new features.

*nix Tip of the Day: Unix Time

As the unix-savvy among you probably know, there is One True Way to tell the time: the number of seconds elapsed since midnight on January 1, 1970 +0000. It's an extremely convenient way for computers to represent the time, since it's just an integer that goes up. There's no parsing to be done, and arithmetic is just regular math. If you want a brain-numbingly-detailed overview, Wikipedia's article on unix time is, as usual, sufficient.

However, what I'd like to talk about here is converting back and forth between unix time and meatware time. I imagine that when your beard gets …

sietchtabr reboot

I have a VM slice that I use to run DNS, a bzflag server, and a few other incidental things. This is what I see on it right now:

% uptime
12:05:13 up 450 days, 15:17,  5 users,  load average: 1.93, 1.35, 0.60

It's currently running Debian lenny, but I decided that I wanted to get with the times and upgrade it to squeeze. As expected the upgrade was fairly painless (took me a bit to figure out that booting by label was broken and I needed to boot by disk UUID), but it's kind …

Linix Tip of the Day: SystemTap

The other day, one of my co-workers, Evan, presented an interesting problem to me. Every day, at some point, a file named ] gets created in his home directory. He assumes that it is being created by a script with a typo in it... somewhere. But how to find out? It's a hard thing to grep for.

My initial solution was to use inotify (which you might remember from a previous post) combined with libnotify to alert him if it happens while he was at his computer. It looked like the following:

$ inotifywait -t 0 --exclude='.*[^]]$' $HOME && notify-send "something just created …
