Jeff Deck and Benjamin D. Herson were men on a mission. Their quest was to travel across the United States, fixing typos on public signs. The Great Typo Hunt: Two Friends Changing The World, One Correction At A Time is their book about the journey. NPR reports:

Some typos were uncorrectable — out of the team's reach, or, as Deck tells NPR's Tony Cox, requiring tools and materials that weren't included in his "typo correction kit."

Deck carried a variety of Sharpies, of which "the black Sharpie was the most important." Deck also carried Wite-Out, dry erase markers, chalk, crayons and pens.

Sometimes Deck and Herson couldn't get permission from the typo-maker to make an adjustment to the signage. "They would turn us down, or they'd be apathetic about it," says Deck.

"Or they'd say 'Oh, we'll fix that one later,' and we'd really have to take their word on that."

Make a guess, and then hit the jump to see if you're correct.

So, as I mentioned previously, JetBlue flight attendant Steve Slater had had enough after 28 years of rude passengers. So he got on the intercom, cussed out the woman who swore at him, and quit his job. After grabbing two beers, he opened the emergency slide to the jetliner to exit the plane. Slater then drove home and was having sex at the time that police arrived to arrest him.

He's become something of a working class hero, and Geekosystem has compiled eight tributes that artists and singers across the Internet have created to honor him. Pictured above is a PSA by artist

It all started when Jeremy Gelbart, one of the founders of Ultrinsic, made a bet with Steven Wolf, the other founder, that he would make an A in a college class. After they graduated, they decided to see if this scheme could work on a larger scale:

Ultrinsic, currently in beta form, allows students at 37 colleges to gamble on their grades in each of the classes they take. The student hands over money to Ultrinsic--as well as access to his or her official school records--as a wager that they will attain a certain grade. If they get it, Ultrinsic pays out on a sliding scale.

A pilot scheme in place at both Penn and NYU over the last academic year had some takers, including one guy who won $150, although the serious money is to be made by high schoolers as they head off to university. Then, if you bet $20 on getting a 4.0 GPA, then you'll walk away with $2,000 should you succeed. That, apparently, is what motivation looks like.

There are 43,252,003,274,489,856,000 possible varying positions for the Rubik's Cube. A team of mathematicians and programmers determined that all of them can be solved within 20 moves:

With about 35 CPU-years of idle computer time donated by Google, a team of researchers has essentially solved every position of the Rubik's Cube™, and shown that no position requires more than twenty moves.

Every solver of the Cube uses an algorithm, which is a sequence of steps for solving the Cube. One algorithm might use a sequence of moves to solve the top face, then another sequence of moves to position the middle edges, and so on. There are many different algorithms, varying in complexity and number of moves required, but those that can be memorized by a mortal typically require more than forty moves.

Researchers led by Tajuki Narumi at the University of Tokyo created a cookie-eating simulator that allows users to believe that they're tasting different flavors, when they're really only tasting one:

To create the effect, the team branded a plain cookie with a distinct logo that the headset tracks via a built-in camera. An air pump sprays out the smell of the chosen cookie, increasing its concentration as the system "sees" the cookie approaching the wearer's nose.

Meanwhile, a visual display in the headset shows an image of the chosen cookie, suggesting the correct texture for that flavour.

The combination of smell and visual texture combine to fool the user's sense of taste into thinking they are eating a flavoured cookie instead of the plain one.

Allegedly, the above photo is one of thirty-three that a woman named Jenny emailed to her co-workers as her resignation letter. Her boss, Spencer, installed Internet usage monitoring software on the company's computers. Jenny had access to it, so she decided to let her co-workers know what Spencer was looking at on the Internet.

UPDATE: It's a hoax.

The photo above is from a 2008 Amsterdam art installation created by the Sagmeister group out of 250,000 coins. In the links, you can find a time-lapse video of the creation of the display. The captions read, in part:

Over the course of 8 days, and with the help of over 100 volunteers, the coins were sorted into 4 different shades and carefully placed over a 300 sqm area.

The coin mural spelled out the sentence "Obsessions Make My Life Worse and My Work Better."

After completion the coins were left free and unguarded for the public to interact with.

Steven Slater, a flight attendant on a JetBlue airliner, got into an argument with a passenger while during boarding at a Pittsburgh airport. He finally had enough of his job, quit, and opened the emergency slide on the plane in order to leave:

He grabbed the intercom and said: "To the passenger who called be a mother ------, ---- you.

"I've been in the business 28 years. I've had it. That's it."

Mr Slater then activated the emergency exit and slid down the inflatable slide on to the tarmac.

He then boarded a train to the terminal, stripping off his tie and discarding it to the astonishment of bemused onlookers.

Slater was later arrested.

Sharpie has developed a new writing implement that's a cross between a pen and a pencil. The writing it produces stays erasable for three days. Then it becomes permanent. At Wired, Charlie Sorrel writes:

The Sharpie Liquid Pencil contains an “ink” made from liquid graphite and lays it down just like a pen. Once written, you have three days to think on the validity and weight of your words. During this period you can erase it just like pencil-marks. After the three days is up, the pencil lines will turn to ink and remain inscribed forever.

Richard Berk, a criminology professor at the University of Pennsylvania, thinks that it's possible to build a computer program that could predict the likelihood that a convicted felon will commit future crimes. These predictions could be used to determine whether or not a convict should be granted parole:

If Berk's ground-breaking computer models work, it could be key for a state parole board that has come under increasing scrutiny for releasing violent criminals well before they reach their maximum sentence, only to see them go on to commit more violent crimes.[...]

Killers who kill again after they are released highlight the need for the state to find a more accurate way to predict which inmates present the highest risk when paroled.

So the parole board has given Berk a $228,000 grant to build his system, pilot it next year and have it in place by 2011.

"We're hoping this will take the board's decision-making to a higher level," parole board spokesman Leo Dunn said. "If a computer program can help prevent the death of someone like [Denise Merhi], then the board wants that information."

Who's been stealing my Twinkies from my cubicle here at Neatorama HQ? This time, I'm going to catch Miss Cellania in the act! Instructables user action_owl designed and built a homemade laser tripwire alarm system that tweets a picture of anyone who crosses it:

This instructable will show you how to construct a laser tripwire that can twitter and grab an image from a webcam, as well as execute any command you can put in a bash script.

This instructable is actually quite simple and is even suitable as a beginner arduino project. It requires a GNU/linux (or possibly Mac) operating system with the arduino IDE and Processing IDE working properly.

I've just discovered a neat retro culture blog that has apparently never been mentioned here. It's called Retrospace, and is packed with advertising, music, fashion, and magazine covers from the groovy 60s and 70s. Posts are sorted into categories in the left sidebar, including "Gastro-Abominations" and "That 70s Home".
