Why Is The Letter "Z" Associated With Sleep?

"Why is the letter Z associated with sleep?"

Interesting tidbit:
That raised the question of how snoring is represented in other cultures. Una discovered the following:
Germans use "chrrr," which considering the typical German pronunciations of ch and r -- i.e., you sound like you're getting ready to use the spittoon -- is a lot closer to snoring than "zzz."
The French, who also favor a sonically rich r, use "rrroooo," "rrr," "roon," "ron," and so on. The Spanish likewise use "rooooon."
The Japanese use characters that transliterate as "guu guu," while speakers of Mandarin Chinese use characters sounding like "hu lu."
Finns use "kroohpyyh," which I'm guessing gives a hint of what I sound like.

Fake Diplomas

Using a Mass Spam Attack to Hide a Cyberheist

Clever trick: "Cyberheist Smokescreen: Email, Phone, SMS Floods".

Here's the basic idea:
Many businesses request some kind of confirmation from their bank whenever high-dollar transfers are initiated. These confirmations may be sent via text message or email, or the business may ask their bank to call them to verify requested transfers. The attack that hit my inbox was part of an offering that crooks can hire to flood each medium of communication, thereby preventing a targeted business from ever receiving or finding alerts from their bank...
If you run a small business and one day find yourself on the receiving end of one of these email, SMS and/or phone floods, I’d advise you to find a mobile phone that isn’t being blocked and alert your financial institution to be especially vigilant for suspicious transactions.

Graffiti from Pompeii

Some examples of graffiti from Pompeii.

Times may change, but human nature does not. (Via Kottke.)

Bad Logic

Spot the fallacy: "There Is a 10% Chance You're Dreaming Right Now".

As one of my Facebook friends noted: "Since the author of the piece has only existed for 0.00000000028571% of the age of the universe, it is a statistical certainty that he wrote it before he was born!"

World’s First 3D-printed Gun

ExtremeTech: "The world's first 3D-printed gun".

This is fascinating from both a technical and legal perspective, especially given that it's the lower receiver that was printed. (This is the part that counts as the "firearm" for legal purposes.) All the other parts can be freely purchased without regulation.

As the article notes:
[T]his means that people without gun licenses — or people who have had their licenses revoked — could print their own lower receiver and build a complete, off-the-books gun. What a chilling thought. But hey, that's the ambivalent nature of technology, the great enabler...
I dare say many gun enthusiasts will find this liberating, not chilling.

Questions to consider:
1) Will this lead to calls for more regulation on currently-legal gun parts or on ammunition?

2) Will the government seek to criminalize possession of the data files necessary to print the critical components (comparable to criminalizing possession of, say, child pornography on one's hard drive)?

3) Or is the cat out of the bag?  ("Can't stop the signal!" as they would say in the Firefly universe.)
One noteworthy comment by member "phurba" on the AR15.com forum:
This is a hot topic on the 3D printer forums. Some people want to make plans for gun parts readily available, either to prove gun laws irrelevant or to circumvent them; while others feel that guns are icky and no such thing should happen.

Anyone who knows me here knows that I am hardly an advocate for gun control, however it is simple for an ineligible person to print a gun and buy the non-gun parts online. Is that something that could be regulated? Not really, unless you regulated the printers. The easiest way to control that is to stop the plans from being posted on public forums.
But let's be honest here: anyone who wants to circumvent these laws could go learn machining and mill their own AR receiver, and the same thing goes for learning CAD software and running a polymer printer. Does that mean that machinists classes and forums should be regulated? Certainly not. I really feel the same argument applied to 3D printers: basically, there's nothing that anyone can nor should do.

Physics of Staying Dry In The Rain

"Physicists tackle a crucial issue: How to stay dry in the rain"

The short version:
Basically, the best strategy for staying dry (or at least somewhat dry) is to run as fast as possible. Unless you’re really thin, in which case there may be a more optimal speed. And if you’ve got a tailwind behind you, then you should run exactly as fast as the wind at your back.

[Off Topic] Civilian Response to Active Attackers

[Off topic]: If you ever find yourself in a mass-shooting incident, how can you safely respond?

My friend Ari Armstrong discusses this with his father Linn Armstrong (a firearms instructor here in Colorado) on what unarmed -- and armed -- civilians can do. For instance, unarmed civilians could throw their movie theater drinks and any available objects en masse at a shooter, thus disorienting him.

Here's the full blog post by Ari and the related video, "Civilian Responses to Active Attackers":

Olympic Trademark Dispute

"US Olympic Committee Forces 30 Year Old Philidelphia Gyro Restaraunt To Change Its Name".

I believe in proper legal protection for trademarks. But this seems over-the-top.

Celebrities Leaving Twitter

The NYT reports that celebrities are leaving Twitter.

Why? In a sentence, "[I]t's a public gaffe waiting to happen".

New Lightest Material

"Scientists Produce the Lightest Solid Material":
[R]esearchers at the University of Kiel recently announced the creation of the lightest solid material ever made, based on a microtube manifestation of carbon. The scientists call their material aerographite, based on the substance's ephemeral quality. Aerographite weighs under 200 micrograms per cubic centimeter, which is a mere quarter of the weight of nickel microlattices—the previous record-holder for lightest solid. Despite its light weight, aerographite is endowed with significant strength based on its microtube lattice structure.

How Times Have Changed: AOL CDs

QOTD from Reggie Fairchild, product manager for AOL 4.0:
When we launched AOL 4.0 in 1998, AOL used ALL of the world-wide CD production for several weeks. Think of that. Not a single music CD or Microsoft CD was produced during those weeks...

How Marketers Exploit Bad Math Skills

How marketers exploit bad math skills and cognitive biases. (Via Instapundit.)

Here's a related excellent 2010 interview with William Poundstone on the psychology of pricing.

One sample story from Poundstone:
I'm a jeweler and for years, we've set up the carts in the malls where we sell the jewelry. And the very first year that we did that, my wife and I, we set up the cart and we sold, you know, the silver chains, sterling silver chains. And we went all around the mall and checked the prices of all the silver chains, and we priced our chains lower than anyone else in the whole mall, and put them out on display.
And they sat, and they sat, and they sat. So we were getting closer to Christmas and worried, so we doubled the price on every chain, and we put a 50 percent off sign in front of it, and they sold like crazy.

Responding to Price Discrimination Software

"Online firms are getting better at calculating how much they can sting you for. Here's how to pay less."

Basically, if sellers are going to analyze your online behaviour to get you to pay a higher price, it's equally fair for you to alter your behaviour to induce them to offer a lower price.

Your E-Book Is Reading You

"Your E-Book Is Reading You".

One tidbit from the article:
Barnes & Noble has determined, through analyzing Nook data, that nonfiction books tend to be read in fits and starts, while novels are generally read straight through, and that nonfiction books, particularly long ones, tend to get dropped earlier. Science-fiction, romance and crime-fiction fans often read more books more quickly than readers of literary fiction do, and finish most of the books they start. Readers of literary fiction quit books more often and tend skip around between books.
Those insights are already shaping the types of books that Barnes & Noble sells on its Nook...
