GigaPan consists of three technological developments: a robotic camera mount for capturing very high-resolution (gigapixel and up) panoramic images using a standard digital camera; custom software for constructing very high-resolution gigapixel panoramas; and, a new type of website for exploring, sharing and commenting on gigapixel panoramas and the detail our users will discover within them. The GigaPan website allows hosting and sharing all kinds of panoramas, and so the robotic GigaPan mount is recommended but is certainly not required to be part of this community.
Check out the Gigapan website.

"Excuse me, can you help me? I promised a friend I would meet him an hour ago, but I don't know where I am." The woman below replied, "You're in a hot air balloon hovering approximately 30 feet above the ground. You're between 40 and 41 degrees north latitude and between 59 and 60 degrees west longitude." "You must be an engineer," said the balloonist. "I am," replied the woman, "How did you know?" "Well," answered the balloonist, "everything you told me is technically correct, but I've no idea what to make of your information, and the fact is I'm still lost. Frankly, you've not been much help at all. If anything, you've delayed my trip." The woman below responded, "You must be in Management." "I am," replied the balloonist, "but how did you know?" "Well," said the woman, "you don't know where you are or where you're going. You have risen to where you are due to a large quantity of hot air. You made a promise, which you've no idea how to keep, and you expect people beneath you to solve your problems. The fact is you are in exactly the same position you were in before we met, but now, somehow, it's my fault."

In June 2006, Warren Buffett gave approximately 10 million Berkshire Hathaway Class B shares to the Bill & Melinda Gates Foundation (worth approximately USD 30.7 billion as of June 23 2006) making it the largest charitable donation in history. The foundation will receive 5% of the total donation on an annualized basis each July, beginning in 2006. Buffett will also join the board of directors of the Gates Foundation, although he does not plan to be actively involved in the foundation's investments. Buffett also announced plans to contribute additional Berkshire stock valued at approximately $6.7 billion to the Susan Thompson Buffett Foundation and to other foundations headed by his three children. This is a significant shift from previous statements Buffett has made, having stated that most of his fortune would pass to his Buffett Foundation. The bulk of the estate of his wife, valued at $2.6 billion, went to that foundation when she died in 2004. His children will not inherit a significant proportion of his wealth. These actions are consistent with statements he has made in the past indicating his opposition to the transfer of great fortunes from one generation to the next. Buffett once commented, "I want to give my kids just enough so that they would feel that they could do anything, but not so much that they would feel like doing nothing".

I made it by editing this pipe to make it suitable for old blogger.
Then I had to adjust it to split the output in two so that we could still have our labels in two columns on the right side. This in done in the lower left quadrant of the image. The image above is for the left column. For the right column I simply hook the lower reverse operator to the output.
I only need to edit this slightly when we reach 1500, 2000, 2500 etc. posts, because the Blogger feed has a maximum output of 500 entries.

I looked up the source of the "top 500 comments" in Yahoo Pipes. I copied and adapted that code to extract the last 500 posts from our blog. I put in a filter that only those with more than 20 posts are shown, bye bye Mr Wiggles and Expendable Asset :P
You can see the pipe I made here. The widget is on our right sidebar under recent comments.
Luckily I still had my old Yahoo account (dare_to_mail_me) so I didn't have to make a new one.
In large-scale field trials, scientists from North Carolina State University have shown that silencing a specific gene in burley tobacco plants significantly reduces harmful carcinogens in cured tobacco leaves.
The field tests in Kentucky, Virginia and North Carolina compared cured burley tobacco plants with the troublesome gene silenced and "control" plant lines with normal levels of gene expression. The researchers found a six-fold decrease in carcinogenic NNN in the genetically modified tobacco plants, as well as a 50 percent overall reduction in the class of harmful compounds called TSNAs, or tobacco-specific nitrosamines. TSNAs are reported to be among the most important tobacco-related compounds implicated in various cancers in laboratory experiments, Lewis said.

I like the idea, but i think i like my privacy more. I don't like it when visitors can see my dirty underwear is washing out. Also the human limbs in my fridge are nobody's business
Audiosurf is a music-adapting puzzle racer where you use your own music to create your own experience. The shape, the speed, and the mood of each ride is determined by the song you choose. You earn points for clustering together blocks of the same color on the highway, and compete with others on the internet for the high score on your favorite songs.It's quite a cool game and a really nice way to explore your music library again. There are a few different game modes and difficulty levels.
You can download a demo at the Audiosurf website, or you can download the torrent, or even buy the game, it's only $9.95 but you have to use Steam. Buying the game lets you use the online functionality where you can compare your scores with those of others and see what songs are popular.
Here is a clip of someone playing David Bowie - Space Oddity.
Mind Gaming' Could Enter Market This YearEmotiv video demo
by Lisa Zyga
In an adapted version of the Harry Potter video game, players lift boulders and throw lightning bolts using only their minds. Just as physical movement changed the interface of gaming with Nintendo's Wii, the power of the mind may be the next big thing in video games.
And it may come soon. Emotiv, a company based in San Francisco, says its mind-control headsets will be on shelves later this year, along with a host of novel "biofeedback" games developed by its partners.
Several other companies - including EmSense in Monterey, California; NeuroSky in San Jose, California; and Hitachi in Tokyo - are also developing technology to detect players´ brainwaves and use them in next-gen video games.
The technology is based on medical technology that has been around for decades. Using a combination of EEGs (which reveal alpha waves that signify calmness), EMGs (which measure muscle movement), and ECGs and GSR (which measure heart rate and sweating), developers hope to create a picture of a player´s mental and physical state. Near infrared spectroscopy (NIRS), which monitors changes in blood oxygenation, could also be incorporated since it overcomes some of the interference problems with EEGs.
Another company, Interactive Productline in Sweden, has a game called Mindball, which isn´t a video game, but uses mind control technology that may lead to video mind-gaming. Two players sit across from each other at a table, focusing on a small white ball. The objective is to make the ball roll toward your opponent and away from you, using only your mind. Headbands measure the players´ alpha waves, and the ball rolls away from the player with the calmest mind.
"Instead of activity and adrenalin, it is calmness and focus that mark the truly successful Mindball Game player," the company explains on its Web site. "Mindball Game is unique amongst machines since it is not controlled by the player´s rational and strategic thoughts and decisions. On the contrary, the participants are dependent on the body´s own intuitive reactions."

@wiki Berkeley was famous for his elaborate musical production numbers that often involved complex geometric patterns. Berkeley's quintessential works used legions of showgirls and props as fantastic elements in kaleidoscopic on-screen performances. He started as a theatrical director, just as many other movie directors. Unlike many at the time, he felt that a camera should be allowed mobility, and he framed shots carefully from unusual angles to allow movie audiences to see things from perspectives that the theatrical stage never could provide. This is why he played an enormous role in establishing the movie musical as a category in its own right.On YouTube you can find more clips.

The image did change without the filter, but I wanted all visible light removed so I took a small piece of photographic film (negative) of a white picture and put it in the place of the old filter. I think I once read that should only block visible light.
Here is the result. I think what you see are near infra-red NIR (IR close to red) images. It sure is not a night vision camera. It actually needs daylight to see anything at all. With an infrared lamp it would work as a night camera though, but no cool "heat" images. Here is the world in (near) infrared through my webcam:

I've chosen two neighborhoods in Utrecht that show quite some contrast as an example.
