Pea PodFrom the article: “A Massachusetts man who was rushed to hospital with a collapsed lung came home with an unusual diagnosis: a pea plant was growing in his lung.”

Superman Comic Saves the Day!

Tuesday, October 5th, 2010

SupermanA US family was facing foreclosure and the loss of the home they’d lived in for decades. Accepting the inevitable, they started sorting and packing the stuff they’d accumulated over the years. And what a surprise they found: issue #1 of Action Comics, the first appearance of Superman. It’s expected to sell at auction for about $250,000 (recent sales of the same comic in better condition have gone for over $1 million). This will save the house from foreclosure, but they had to get a comic book dealer to call the bank and explain the situation.

A Great American Invention: The Supermarket

Friday, September 17th, 2010

Shopping CartSupermarkets did not exist prior to the 20th century. Free parking and the invention of the automobile ignition switch were key factors in their rise, and the lower prices during the Great Depression helped as well. The shopping cart was a relative latecomer to the scene, not being invented until 1937. The linked article explains all this and more.

The Comedy of Errors Leading to the BP Oil Spill

Wednesday, September 15th, 2010

BP LogoBP’s internal investigation into the Deepwater Horizon oil spill has uncovered eight unique problems that allowed the explosion and spill to occur. They run the gamut from poor practices/training to equipment failure and bad design.

It’s almost unbelievable how many things had to go wrong in order for the spill to occur, especially since many of them would not have happened if BP was on top of things. For example: “These tests indicated a problem … but were ‘incorrectly accepted as successful,’ in part because there were no standards in place for what constituted a negative test.” There’s also: “That returns us to the automated system that was attempting to shut the blowout preventer. Even though it kicked in, once the explosion happened at the surface, it lost power.” And then finally: “Redundant hardware on the sea floor was designed to operate independently. Unfortunately, it also failed; one of the devices had a fault in a critical piece of hardware, while the second had insufficient charge in its batteries to function.”

Enter the Candwich

Thursday, September 2nd, 2010

CandwichI suppose it was just a matter of time before someone put a sandwich inside a can. Apparently the hard part was developing a shelf-stable form of bread that can stay fresh for up to a year. Here’s hoping the inventor, Mark Kirkland, makes a ton of money from his idea.

The “God Number” for a Rubik’s Cube is Exactly 20

Tuesday, August 24th, 2010

Rubik's CubeResearchers have proven, using mathematical techniques and a heavy amount of computing power, that 20 is the maximum number of moves necessary to solve any Rubik’s Cube configuration by the shortest method. This value is known as God’s number. They were able to mathematically reduce the number of unique patterns from 43,252,003,274,489,856,000 to a mere 1,090,175,792,696,524,800 (one quintillion). Then they used something on the order of 35 CPU years of processing to verify that each of the remaining combinations could be solved in 20 moves or less.

Trading a Cell Phone For a Porsche on Craigslist

Tuesday, August 17th, 2010

Red PaperclipLong-time Chad’s News readers will recall how Kyle MacDonald made a series of trades to go from a single red paperclip to a house. Well now, a teenager named Steven Ortiz started with an old cell phone and made deals on craigslist to trade up to a working Porsche Boxster. Admittedly, it took him 14 swaps over two years, but that’s still pretty impressive.

The Ultimate Effect of Lossy Compression

Wednesday, June 9th, 2010

BitsAudio, video, and image files are so large that they effectively can’t be used on the internet, or in portable devices like cameras or iPods, without somehow making them smaller. And while there are ways to compress files without losing any of the data (think ZIP files), most of the formats we use today, MP3, JPEG, GIF, MP4, AVI, etc., use lossy compression. A song saved in the MP3 format, for example, throws away some of the audio but does it in such a way that most people don’t notice the difference.

But repeatedly compressing the same file will cause it to lose more and more of the actual data—sort of like making a photocopy of a photocopy. This is why I don’t use Audacity to edit MP3 files, because it first converts them to the WAV format for editing then back to MP3 for saving.

The linked article shows what happens to a video that was re-saved a thousand times. The author created the original video, uploaded it to YouTube, downloaded it, uploaded it again, and so on until he had a thousand uploads. The final video very clearly shows the cumulative effect of lossy compression.

The Loss of Anonymity in the Information Age

Saturday, April 3rd, 2010

AnonymousEvery so often a business or government entity will attempt to release “anonymized” data only to find that the anonymization process fails miserably (AOL, Netflix). The problem is not so much with the actual data itself, but is in how it can be combined with other data sources to identify specific individuals. A researcher has shown that 87 percent of Americans can be uniquely identified with just their ZIP code, birthdate, and gender.

Smoking Bans of Yore

Tuesday, February 16th, 2010

Mr. ButtsModern-day smoking bans are becoming more and more restrictive, but they don’t even come close to some of these draconian bans from the past—which include excommunication and summary execution as punishments.
