The ultimate evil computer program:
I'm sure glad that nothing could possibly go wrong when building an evil intelligent computer program... (Via Morality War.)
A group of scientists is building the world's most evil computer program. This isn't a B-movie setup: A team at Rensselaer Institute's AI & Reasoning Lab is bringing personified evil to virtual life in the hope that they'll unlock the secrets of human morality. The researchers have given their creation a face and a name, and quiz it daily, using its answers to further blacken its hideous character.More info here.
Selmer Bringsjord, director of the AI lab and chairman of RPI's Department of Cognitive Science, has created "E," a computer-generated character programmed according to his own definition of evil. E must, according to Bringsjord, be willing to carry out premeditated acts that are immoral and would cause harm to others. And, when E analyzes its reasons for wanting to commit such acts, it must either develop a logically incoherent argument or conclude that it desired to see people harmed.

Shameless plug: My radiology practice Invision/Sally Jobe gets mentioned in this October 28, 2008 story in the Wall Street Journal, "CT Scans Gain Favor as Option for Colonoscopy".
The article quotes one of my partners, Dr. Richard Obregon, who was one of the co-authors of the recent September 18, 2008 paper in the New England Journal of Medicine on this topic, "Accuracy of CT Colonography for Detection of Large Adenomas and Cancers".

"Wikipedia and the Meaning of Truth".
Simson Garfinkel discusses the problems that arise when truth isn't based on adherence to the facts of reality but instead to a mixture of authority and social consensus:

Unlike the laws of mathematics or science, wikitruth isn't based on principles such as consistency or observability. It's not even based on common sense or firsthand experience. Wikipedia has evolved a radically different set of epistemological standards--standards that aren't especially surprising given that the site is rooted in a Web-based community, but that should concern those of us who are interested in traditional notions of truth and accuracy. On Wikipedia, objective truth isn't all that important, actually. What makes a fact or statement fit for inclusion is that it appeared in some other publication--ideally, one that is in English and is available free online. "The threshold for inclusion in Wikipedia is verifiability, not truth," states Wikipedia's official policy on the subject.

Problems with early e-voting? From CNN (emphasis mine):
(Via Techdirt.)
...[R]eports of problems are troubling signs for many who are skeptical of whether their votes will count.Personally, I don't regard "it's just been doing that" as a very satisfactory response from government representatives. If American voters don't have confidence in the legitimacy of the outcome, this election could be historic in more ways than one...
Forty-two percent of those surveyed in a recent CNN/Opinion Research Corp. poll said they were not confident that their votes could be "accurately cast and counted."
... In West Virginia's Jackson County, there were some reports that voting machines were accidentally recording the wrong vote.
"I went in there and pushed the Democrat ticket, and it jumped to the Republican ticket for president of the United States," said Calvin Thomas, an 81-year-old West Virginian...
The same thing happened to his daughter, Micki Clendenin, when she cast her ballot. In both cases, poll workers at the site had them touch the screen a few more times, and the voting machine changed their ballot to their candidate choice.
"The lady came in, and she was -- very nicely, she just said, 'it's just been doing that.' She said, 'just hit it again.' So we hit it again, and this time it did go to Obama," Clendenin said.

You can chat with Elbot yourself, and perhaps help improve its algorithm so that it might win next time.

Some rock bands are making more money from Guitar Hero releases than from their albums:
...Aerosmith have made more money from "Guitar Hero: Aerosmith" (pictured above), a version of the video-game that features the band, than from any of their albums. Mr Kotick [of Activision] has even suggested that rather than expecting games companies to pay to license their music, bands should pay to have their music included in games.
...Metallica's new album Death Magnetic" was made available as a download for "Guitar Hero" on the day of its release. (Fans have pointed out that the video-game version actually sounds better than the album.)
Combat zone shopping:
One of the unexpected military impacts of the Internet is the stress Internet shopping has placed on the military mail system. It works like this. Americans can cheaply send things to a soldier overseas, because the troops use a special military address in United States. The military then pays for shipping letters (less frequently) and packages (much more frequently) to wherever the military recipient is on the planet. Because of the ease of shopping online, and the near-universal access to the Internet by troops overseas, more stuff is being bought online and shipped overseas largely at government expense. In 2006, the Department of Defense shipped 112,000 tons overseas. In 2007, that was up to 139,000 tons. This year, it's headed for a total of 180,000 tons. It costs the Department of Defense over half a billion dollars a year to move this stuff, most of it moving by air.
Internet shopping became important both because it improves morale, and also saves lives. Little luxuries mean a lot, and just about anything is available via the Internet. This includes things like Netflix (the low cost two discs a month deal works well with troops overseas). But troops also buy military equipment (and some weapons, like knives) as well. Special clothing and equipment (tools, flashlights, goggles, etc.) are the most common items ordered. When one trooper finds a new item that works real well, the word gets around very quickly. The troops have a network of message boards, social sites (MyPage, FaceBook) and email lists (listservs) that keep everyone informed. Some companies have found themselves quickly sold out of an item, days after a soldier or marine found that, "hey, this works." A lot of those popular gadgets are lifesavers, all because the Internet and the military postal system gets the stuff to the troops quickly and cheaply.

"The Maryland State Police classified 53 nonviolent activists as terrorists and entered their names and personal information into state and federal databases that track terrorism suspects..."
The article also notes:
(Via IPList.)
The article also notes:
Both [former state Police Superintendent Thomas] Hutchins and [current Police Superintendent Terrence] Sheridan said the activists' names were entered into the state police database as terrorists partly because the software offered limited options for classifying entries.The 1940's excuse of "I was just following orders!" has now apparently now been upgraded into "The software left me with no other choices!"

"Can the President grant immunity from prosecution?":
I love Fox's 24. A common plot device in the show is for the bad guy to demand and get a letter of immunity from prosecution signed by the President in exchange for some vital piece of information. The immunity always seems to hinge on the information being true and resulting in the capture of some villain or the recovery of the explosive du jour. Is any of this true? Can one demand immunity from prosecution signed by the President, and, more importantly, can one expect to get it?

Prison currency is no longer the cigarette, but rather the mackerel:
There's been a mackerel economy in federal prisons since about 2004, former inmates and some prison consultants say. That's when federal prisons prohibited smoking and, by default, the cigarette pack, which was the earlier gold standard.(Via Marginal Revolution.)
Prisoners need a proxy for the dollar because they're not allowed to possess cash. Money they get from prison jobs (which pay a maximum of 40 cents an hour, according to the Federal Bureau of Prisons) or family members goes into commissary accounts that let them buy things such as food and toiletries. After the smokes disappeared, inmates turned to other items on the commissary menu to use as currency.
...[T]he mack is a good stand-in for the greenback because each can (or pouch) costs about $1 and few -- other than weight-lifters craving protein -- want to eat it.

Play Tetris in Mac's Terminal app:
Here's how to do it.
First, open a new Terminal.app (/Applications/Utilities) window and type "emacs," then hit enter.
After the screen loads, press "escape," then "x."
Type "tetris" (lower-case) and hit enter.
There you have it, a fully playable game of Tetris. Use the arrow keys to control the blocks.

"Spontaneous traffic jams are like detonation waves":
We're all familiar with phantom jams, traffic blockages that arise with no apparent cause and that melt away for no discernible reason.
Today Ruben Rosales and pals at MIT and the University of Alberta in Canada coin a new term for the waves that cause these hold ups: they call them jamitons.
