3D Time Travel (and the future?)
While searching for an image of a stereoscope, I came across Early Visual Media, a kind of archeological museum of image culture. The aims of the site are diverse and varied. It's certainly entertaining and very educational. Among the stereoviews, you'll find some nudes and related collections from the 1800s! Yes, your grandmother's grandmother was a flousey. And although she is dust, she looks pretty hot. The site's creator, Thomas Weynants, has an exhaustive bibligraphy of publications and links. Television in its earliest forms is among his interests.
There is a fLIckr group of stereo photography--actually several groups divided into parallel, cross-view, and anaglyph factions. Can't we all just get along? Via Xorsyst, I found the wonderful fLIckr site of Okinawa Soba and his T-Enami dedicated site as well. Since we're on the subject, you could start at this 3D set and his instructions for parallel viewing. I may require several years to fully explore Rob Oechsle's collections.
Digital stereoscopy is slow to get started despite what seem to be advantages. I think it is more practical than ever before, as all photography now consumes fewer resources. Only the design of the camera lens --not all components-- would need to be effectively doubled. An 8-megapixel camera would become a camera which takes two 4-megapixel images and stores them in a single image. Three-dimensional photographs would have much more information (regarding depth) than 2D photos and would have applications in forensic analysis, for example. Surveillance cameras might benefit from 3D video imaging as well. In addition to depth, the photographer who wishes to use the 2D image has 2 slightly different versions (of the 2D image) to choose from. Dust and scratches could be more easily removed with a second image as a reference. Perhaps a new file type like the JPEG could be created, but in principle it should not be necessary. The left-eye and right-eye images can just be recorded side-by-side in a single wide jpeg. EXIF data or some tag in the 3D jpeg could indicate to software that this is a stereoscopic image. (Alternatively, software might detect this fact automatically.) In that case, additional tags could indicate from several options for displaying the photo. The left and right sides of the photo could be displayed straightaway in parallel as a default. A tag indicating cross-eyed viewing could instruct software to divide the image and display the right-eye image on the left and vice-versa. A third way to view it would be to display the right-eye image and the left-eye image in the same frame in rapid succession, like an animated GIF, producing the illusion of three dimensions in this way (the "wiggle" method). This works for people with one eye since it fools the brain rather than the eye. Another technique would be to specify either the left or right or the image as a default to display, and the other half to display upon mouse-over.
There are a few easy adjustments to be made on the software side before stereoscopy can experience a mainstream boom or revival. I would hope that a digital camera maker would come out with stereoscopic model soon and find it to be extremely popular. Alternately, the development of 3D display technology may be driven from the display side, it a breakthrough occurs there first and enables the easy viewing of 3D content on inexpensive screens.

More goat
Newspaper claims suspect transformed into a goat
Fri Jan 23, 6:07 pm ET
LAGOS, Nigeria – One of Nigeria's biggest daily newspapers reported that police implicated a goat in an attempted automobile theft. In a front-page article on Friday, the Vanguard newspaper said that two men tried to steal a Mazda car two days earlier in Kwara State, with one suspect transforming himself into a goat as vigilantes cornered him.
The paper quoted police spokesman Tunde Mohammed as saying that while one suspect escaped, the other transformed into a goat as he was about to be apprehended.
The newspaper reported that police paraded the goat before journalists, and published a picture of the animal.
Police in the state couldn't immediately be reached for comment.
Belief in black magic is widespread in Nigeria, particularly in far-flung rural areas.

Google Charts QR-Code API
Google charts dynamically generates various kinds of charts as you need them--right in your browser or on a web page. Venn diagrams, bar graphs, pie graphs, and even maps are available! An interesting one is the dynamic generation of QR codes. A very appealing feature is that you can set the EC (error correction) level on these. I didn't see this in other online QR code generators. EC level H allows your code to be readable even if 30% of your code is obscured. That should be ideal for the purpose of embedding it in a manipulated image. It compares to the default level L, which only allows 7% of the data to be restored. Version number is set automatically depending on your request. I'm a little drunk now, so I may not be able to summarize it very well. Al Khahol can make you geeky (cuz it definitely don't make you sexy (unless the opposing party is even more drunk)).
Basically, you start with
http://chart.apis.google.com/
and add the chart type (cht)
chart?cht=qr
to indicate you are making a QR chart. Then you can add the other specifications or parameters, such as size. You can't get much smaller than 40 for a QR code, and I'm not sure what the upper limit is… (177x177 -- but you could be using multiple pixels per bit). Suppose it's 200x200.
&chs=200x200
That (chart size, chs) is obligatory. The output encoding default is UTF8 so you don't really need to add that. You could encode you Japanese kanji using Shift_JIS
&choe=
Shift_JIS
otherwise you can leave it out. ISO-8859-1 is also available, whatever the hell that is.
Specify the L, lingual string(?) with
&chl=
Then my favorite part ,
chld=<L, M, Q, or H>
This is the EC and margin, where you can specify error correction and margins, according to Google,
Four levels of error correction (EC) are available. The default level (L) allows the QR code to be read even if up to 7% of the code is misread, missing, or obscured. Other levels provide error correction for codes where up to 30% of the code cannot be read. The number of characters that can be encoded decreases as the EC level increases. See Versions, error correction and maximum characters for details.examples:
The default margin is 4 modules. This means that a blank space equivalent to four rows at the top and bottom and four columns on the left and right is placed around the QR code. This is the minimum required by QR readers.
Optionally, specify an EC level and margin with
chld=| Where: is one of the following: L allows 7% of a QR code to be restored M allows 15% of a QR code to be restored
Q allows 25% of a QR code to be restored
H allows 30% of a QR code to be restored
anddefines the margin (or blank space) around the QR code. The default image has a margin equivalent to 4 rows / columns of the chart.

Witness to History
Hello, President Obama!
Mr Cheney and his gloves. He leaves no fingerprints.
See ya!
To President Obama: Congratulations!
To my fellow Americans: Yay!
To my fellow world citizens: Sorry for the last 8 years.
To my fellow expats: What next?

America's Pet Goat
The hooved and horned one will be gone in a few moments. The long national nightmare has ended.
Update: I must say that if there was a purpose for George W. Bush's life and reign, it was to create the conditions for the rise of Barack Obama. Perhaps we should be thankful to Governor Bush for that.

Tony Blair Witch Project -- continued
It lives! This is from a cellphone snap of a BBC broadcast. A small amount of post-processing has brought out the beauty of Tony's features. His "W" is still visible, although it may be getting botoxed out gradually and tastefully, Blair-style. Or is it becoming a "YY"? Is it just me or is he starting to look a little like either Dwight Eisenhower or Don Knotts (if they had appeared on Six Feet Under)?
Notice how the Israel-Palestine conflict has just magically disappeared since Blair has combined his flair for diplomacy with that of Condoleeza "Destroyer of Worlds" Rice? Tony, yer doin' a heckuva job!
This is one more possible fate for Obama to avoid; don't become Blair, Clinton, or Carter. He's already managed to avoid becoming Dukakis, Gore, Kerry, and Jesse Jackson.

Few favors for feathered friends from frequent fliers
The accident also raised questions about whether airports around the country are doing enough to deal with bird flocks.Source: AP news article in the IHT
The agency that operates New York City's major airports said it has a multimillion-dollar program to chase birds off its property, but can only do so much to protect planes once they are in the air.
The Port Authority of New York and New Jersey said it kills thousands of birds every year in the marshy waterways and tidal flats that surround its two major airports in Queens, and uses guns, pyrotechnics and hawks to drive away birds.
Among the other tactics: Bird eggs are coated in oil to prevent them from hatching. Nests are removed. The agency also plays recordings of bird distress calls, and landscapers remove any shrubs and trees that might be attractive to certain species.

Swarm-bots
The swarm-bot concept and implementations are impressive, but what was the scientist(/performance artist?)'s motivation for using a living human girl (the symbol of the hope and future of humanity?) for this demonstration, rather than a dummy (dressed in fatigues, say), mannequin, bag of flour, or something else?
Here's my kwik remote psychoanalysis: The creator(s) see their creations as beautiful. To them, they are like children. They want you to see them as cute, colorful, intelligent, helpful tools. They are probably tired of people seeing these as potential vacuum cleaners or luggage trucks and want to jump-start the public imagination to see the swarm-bots in hospitals, refugee camps, de-mining, doing humanitarian work and winning the Miss Universe contest. They are protecting the children. In short, some of the humanity of the child should rub off on the swarm-bots just by being photographed together. They think this is good PR.

Stereo-card collection
This is a collection of stereoscopic postcards from the San Diego Historical Society. I keep waiting for stereoscopic digital cameras to come out, but it seems I'll have to wait a bit longer, perhaps for a cheap and high quality display technology.

CH4 on Planet Four
A Banner Day
The scowling, muzzled visage of vice Richard "Dick" Cheney, traces of his sidekick Governor "W" Bush and moll, and the twisted, satanically-W-inscribed fo'ead of Tony "W" Blair have long held a place in the banner image of this blog, reminding you, the reader, that the world is full of kindly elderly gentlemen (and ladies) who secretly wish to hurt or kill you and chew off your face. Although I hesitated to remove these reminders of an earlier time before the inauguration due to a lingering paranoid suspicion that Mister Cheney's minions would crash a fleet of airliners into the inauguration ceremonies, decimating the attendees and leaving Mister Cheney as the highest-ranking surviving government official in the Secure Undisclosed Location from which he would emerge and declare himself ruler for life in a new Republic, I feel that the probability of such a plot succeeding, were it to be attempted, is safely low enough that I can delete his muzzled mug and all signs of the others and allow myself to imagine and enjoy an era when they are slowly forgotten. They have been replaced with a sunflower, a lotus blossom, and --lest we forget and lower our guard-- a bee.

404 - File not found
This is post number 404. I have deleted some posts before, and will do so again, so it's a meaningless number, especially since I am thinking to post (and post-date) some things I have been doing since November 9. This marks the end (perhaps) of an extended period of non-blogging. This has been a time for reading, listening, and action other than blogging. (I did add some feeds of Japan bloggers to the sidebar, though.) There are dozens of candidate topics for blogging daily, and I have reverted to sending mass e-mails, so I will try to resume blogging, perhaps by e-mailing posts. Blogging is just not a very high priority in the big scheme of things, as much as I would like to do more of it.
I have never been a fan of the "Blogging will be light the next few days" sort of message. This just seems wrong for several different reasons. First, it is presumptive about the future. I may be dead in the next few days. In that event, any "Blogging will be light" prediction will seem quite ironic. It is similar to signing in for every day of the month at the beginning of the month. Second, it assumes that there are readers, that the readers are sentient beings, and that the readers care. There may be no readers (statcounter could be fibbing?), those readers could be bots and spiders, and the reader(s) could be apathetic or hostile to the perceived probability of future postings. Finally, self-referential scribblings will accumulate and distract, eventually forming a large proportion of one's posts. If 20% of a blog's posts are about the expected frequency of future posts, or apologies for past nonexistent posts, it would be a nuisance to read. Fundamentally, this blog is not to serve or build a community of readers, but just for me to express myself. I would like to have one or more readers, but not too many more than that.
However, having said that, I will try to resume blogging (but it may be light for the next year or two…). I list no email address, but comment modulation is on and results in an email sent to my account, so post a comment to send me a mail. I have only rejected one comment, and that because it was about ten thousand words in German about UFOs. I guess there was no upper limit on comment length at that time, but it exceeded my own upper limit, which is that comments must be no longer than the cumulative content of the entire blog, at least, particularly when in a non-English lingo.
Happy New yEar, reader! It's a cow. The end of the noughties is within countdown range and the teenies will be upon us soon. After '09 the "twenny" will come into use, as in "twenny-ten".
