The Mathematical Magic of the Fibonacci Numbers. A solid introduction to one of math’s cooler patterns. If the Intelligent Design folk were smart, they’d go after the patterns in nature. Unfortunately, intelligence isn’t one of their strong suits.
It’s been about a month since the last desktop change, so I was itching for something new. I’ve been combing through some of my old stuff, trying to put together a portfolio page and found this wallpaper that I never finished. Made it in March of 2004, seems fine to me. Also had the presence of mind to make it at a nice big resolution, so there are a few different size options.

I would also like to point out that I seem to have some bizarre stuffed animal fetish for wallpaper. Also, this one has Optimus Prime in it.
What should you do when you’re counterfeiting currency and your printer jams? Buy a new one with all your cash? No, you send the printer off to be repaired.
MIT has unveiled the production version of Negroponte’s $100 laptop. It’s hard to express how happy I am. It has the potential to make a huge difference in terms of African connectivity. Not just for education but in terms of an expanded business base and a route for freedom of speech.
My interest lies mostly in some research I did for my alternative practicum at teacher’s college. I was looking into the possibilities for internet aided learning in remoter regions of Sierra Leone. Cell coverage is spotty, but it’s improving by the day with new telecomm service. So, getting a data connection is possible, the harder part is maintaining an adequate power supply for your computing equipment. That makes that hand-crank on the laptop one of the most important features.
I investigated a number of solutions, eventually settling on handheld pdas and portable solar arrays. The power consumption is fairly minimal, the batteries are rechargable and you have the possibility of using a laptop as a central base-station. The laptops and/or pdas could come from anyone really. There are relatively inexpensive portable solar arrays available now that are capable of powering most of those devices. My ideas were partially inspired by Ben Saunders’ trek to the arctic and his blogging via pda (he used this rollable solar array).
The Junction Box is also an amazing piece of hardware. Combining a few of Negroponte’s laptops and portable Wifi router with direct cell-network capabilities creates some pretty cool options — like a mobile classroom. You could slap one of those in a jeep, but a pile of laptops in the trunk and drive around from school to school.
The science behind four interesting physics demos, including: walking on broken glass, dipping your hand in molten lead, having a concrete block smashed on your chest while sandwiched between a bed of nails and picking up a white-hot space-shuttle tile.
These Scarface posters are amazing (make sure you look in close), reproducing all 300 pages of script. Alanah did a series of Alice in Wonderland drawings in a similar style, we’ll see about getting them online.
Just wanted to post a few photos from the roll of film I got back recently. They’re not news to those valiant flickr stream observers, but my posts over there aren’t as freqent with the semi-broken digital camera.
E. W. Dijkstra Archive features a compilation of his various manuscripts. The founding father of computer science believed it was a scientist’s duty to maintain a lively correspondence with his scientific colleagues. And he followed through.
