Christmas time… time for colorful lighting. 🙂
The chicken we had for lunch last Sunday protected itself against the NSA but not against five hungry mouths…
Okay, this already happened a while ago but I just stumbled across it again caused a big fat smile. 😀
A few years ago Apple (AppleCare to be exact) sent me a very special tool along with my warranty replacement iPhone 3GS: a paper clip. What should I say: a perfect replacement. 🙂
I’m not sure what to make of this: last evening I played around with a new hardware device (a TP-Link TL-MR3020 router, but that’s not the point). I was leaving the room and just as I turned off the lights I noticed a green spot on my desk. The USB power supply of the device emitted a green phosphorescent glow (Wikipedia).
I’m not sure why the manufacturer used a phosphorescent material for the case of the power supply, but the effect is quite impressive (creepy) and lasts for some minutes. By the way, it’s a Huntkey Switching Power Adapter model HKA00605010-3B.
I was lucky to be in the first group of people to receive two TI Stellaris Launchpad LM4F120 Evaluation Kits. Hurray! 🙂
I bought both kits for 9,98 US $ directly from TI. Here some photos from the unboxing. I will update this post as soon as I get a development environment up and running. For everyone who can’t wait: there is a nice “Getting Started” page from TI with video tutorials and tons of information.
P.S. I like the comment of the Stellaris MCU Team in the box: “Happy Coding!” 😉
I just received my Raspberry Pi board from Farnell (element14). It’s the new Model B, Revision 2.0. 🙂 I originally wanted to use the board as a cheap always-running gateway. But the more I’m playing around with it, the more I enjoy its multimedia capabilities.
By the way, I’ve attached the Raspberry Pi to a power meter. According to it, the board consumes 3.1 Watt when idling and 3.4 Watt when compiling code or installing new packages. The attached mouse, keyboard and the network cable connection (wireless connection is planned) also drain some power. When being shut down, it still consumes 1.0 Watt (which might be due to the cheap USB power supply).
…the number of “hops” needed to connect the author of a paper with the prolific late mathematician Paul Erdős. An author’s Erdős number is 1 if he has co-authored a paper with Erdős, 2 if he has co-authored a paper with someone who has co-authored a paper with Erdős, etc. (Hoffman 1998, p. 13).
In my case, the following collaboration path results in an Erdős number of 3… 🙂

Working with a good friend of mine on some movie projects seems to have paid off: I have my own page on the Internet Movie Database… 😉
