What is Xeroderma Pigmentosum?: "Xeroderma Pigmentosum
A rare genetic defect in ultraviolet radiation induced DNA repair mechanisms; characterized by severe sensitivity to all sources of UV radiation (especially sunlight).
XP is categorized in at least eight complementation groups according to the capacity of the body to repair DNA. These groups (i.e., genetic subtypes) are labeled A through G, plus the XP variant: XPV. Groups A, C, D, and Variant make up over 90% of XP cases. Group A, for example, has the lowest level of DNA repair and the most neurological manifestations. "

Bird Computer� 6502 Page: "How to obtain TV Video Output From an FPGA
This project arose from my desire to have color video output to a TV rather than an expensive monitor. Most of the sample circuits I've seen for hobbyist type video output use VGA output to drive a monitor. Interfacing to a VGA monitor is relatively easy and provides a high quality video output. But what do you do if you don't have a VGA monitor to spare ? Many hobby type projects do not have the memory capacity or performance to drive a VGA monitor. Even used VGA monitors in good working order can be relatively expensive. How about using a TV instead ? It turns out that interfacing to a TV is almost as easy as interfacing to a VGA monitor. I came up with the following two circuits, the first of which I've built, the second of which I'm pretty sure will work. Schematics for the circuits are here: vdac.pcx"

FPGAs are fun!: "'Dragon' FPGA board
Feb 27th 2004 - The board is available for sale in limited quantities (go to the shop for the latest pictures).
This is the lastest board on this site. Dragon has the following characteristics:
Based on Xilinx's Spartan-II XC2S100TQ144.
PCI/USB/I2C/JTAG interfaces
8051 microcontroller (on the back of the board). Use of the 8051 is optional. When in use, the 8051 and FPGA can communicate through an 8-bits synchronous bidirectional bus.
Prototyping area/which can accomodate two RJ-45 Ethernet connectors
Top and bottom SIL connectors - can plug into a wide 'solderless-breadboards' for experiments.
Has a dual-row connectors, so can be used as motherboard for other projects.
Two onboard clocks: a fixed 24MHz clock, plus a socketed 3.3V DIL-8 oscillator.
Top IOs are configured to accept LCD text modules; option to accept a graphical LCD panel (in development).
100% plug'n play, i.e. you can download the FPGA and the 8051 from the PC (through the USB). Doing both takes less than 1 second. "

Digilent Inc. - Digital Design Engineers' Source: "Digilab XCR"The “all-in-one” XCR Board (XCR) features a 64 macrocell, 1600 gate Xilinx CoolRunner CPLD and several useful I/O devices. The XCR runs on 2 AA batteries, it works seamlessly with Xilinx’s free WebPack tools, and it ships with a programming cable, so designs can be completed anywhere a PC exists with no additional costs. The XCR provides an ideal platform for engineers who want to learn digital design techniques using modern technologies.
TheDenverChannel.com - News - 'Jews Killed Jesus' Sign Causing Controversy: "A billboard unveiled on Ash Wednesday, the same day that a controversial movie depicting the last hours of Jesus Christ premiered, is sparking criticism from people of all faiths.
The large-size outdoor marquee, which sits on the property of the Lovingway United Pentecostal Church at Colorado and Mississippi, says, 'Jews Killed The Lord Jesus' and the word 'Settled!'
'It's settled,' said Maurice Gorden, Loveway pastor. 'The word of God is the final word.'
The Anti-Defamation League asked for the marquee to be changed because it is anti-Semitic, but the church only amended the billboard slightly by removing the word 'settled' and attributing the line to biblical Scriptures.
That, however, is still not appeasing critics."

Microsoft, Amid Dwindling Interest, Talks Up Computing as a Career: "Nationally, there is a similar trend. The Computing Research Association's annual survey of more than 200 universities in the United States and Canada found that undergraduate enrollments in computer science and computer engineering programs were down 23 percent this year."
Microsoft, Amid Dwindling Interest, Talks Up Computing as a Career: "John V. Guttag, head of the university's electrical engineering and computer science department, points to the 'worrisome' downward trend. In the current academic year, 229 sophomores selected his department as their major, down from 282 in 2002 and 342 in 2001, a 33 percent decrease in just two years. "

101 Amazing Earth Facts: "16. What was the strongest earthquake in recent times?A 1960 Chilean earthquake, which occurred off the coast, had a magnitude of 9.6 and broke a fault more than 1,000 miles (1,600 kilometers) long. An earthquake like that under a major city would challenge the best construction techniques."
101 Amazing Earth Facts: "14. What is the largest volcano?
The Mauna Loa volcano in Hawaii holds the title here on Earth. It rises more than 50,000 feet (9.5 miles or 15.2 kilometers) above its base, which sits under the surface of the sea. But that's all volcanic chump change. Olympus Mons on Mars rises 16 miles (26 kilometers) into the Martian sky. Its base would almost cover the entire state of Arizona."

101 Amazing Earth Facts: "3. What makes thunder?
If you thought, 'Lightning!' then hats off to you. But I had a more illuminating answer in mind. The air around a lightning bolt is superheated to about five times the temperature of the Sun. This sudden heating causes the air to expand faster than the speed of sound, which compresses the air and forms a shock wave; we hear it as thunder."

101 Amazing Earth Facts: "1. What is the hottest place on Earth?Count one wrong if you guessed Death Valley in California. True enough on many days. But El Azizia in Libya recorded a temperature of 136 degrees Fahrenheit (57.8 Celsius) on Sept. 13, 1922 -- the hottest ever measured. In Death Valley, it got up to 134 Fahrenheit on July 10, 1913. "
Water on Mars? Flood of Data, Trickle of Answers: "Spheres remain a mystery
No more information was provided yesterday on spherical grains in the soil and rock of Mars that have puzzled geologists since early February.
The spherules, as they are called, might have formed in the presence of water, but they could also be the result of a volcanic eruption or meteor impact. This week a couple of spheres were sliced in half and photographed, but they've not been fully analyzed. "
