What Made The AK-47 So Popular?

Why are AK-47s sometimes referred to as Kalashnikovs?

That name would be a nod to the rifle’s inventor. Mikhail Kalashnikov was born to a farming family in southern Russia in 1919. As a boy, he wanted to become a poet, but like a lot of young Russian men he ended up in the army instead. Kalashnikov rose through the ranks to become a tank commander until he was wounded while fighting Nazis at the Battle of Bryansk in 1941.

While Kalashnikov was convalescing he began poking around in small arms design.

A fellow soldier had asked Kalashnikov why the Russians weren’t as well armed as the Nazis, each of whom had his own automatic rifle. Kalashnikov started tinkering with designs for an automatic rifle that could help defend his country, and he finally perfected his design in 1947. The rifle is officially known as the Avtomat Kalashnikova (Automatic Kalashnikov), and the “47” derives from its year of completion.

What made the AK-47 so popular?

One might think that the AK-47’s wild popularity stems from pinpoint accuracy. Think again. The standard issue AK isn’t particularly accurate; it’s best in relatively close-range combat situations rather than distant engagements.

The AK-47’s major selling points are its simplicity and its ability to take a beating. The rifle was designed to be easy to use, easy to repair, and reliable. The ruggedness of the gun makes it the perfect weapon for dirty, sandy conditions or for soldiers who might not be super disciplined about maintaining their firearms. Its simple firing mechanism means that the gun jams very rarely. Depending on conditions of use, an AK-47 can have a service life of anywhere from 20 to 40 years.

We see terrorists and rebels with Kalashnikovs all the time. How many are out there?

The AK’s ubiquity isn’t simply a testament to its reliability. It’s also partially a function of the mind-numbing number of Kalashnikovs that have been produced. Oxford economist Phillip Killicoat cites an amazing statistic in his 2006 paper “Weaponomics: The Economics of Small Arms.”

There are somewhere around 500 million firearms worldwide. Around 100 million of those are some sort of Kalashnikov, with the AK-47 leading the way with roughly 75 million units in existence.

Huge production numbers coupled with a long service life have littered the globe with AKs. Killicoat’s paper cites another big reason for the AK-47’s global status: the Soviet government may have been stingy with its own people, but it was awfully generous when it came to giving away or selling Kalashnikovs to regimes and rebel groups it supported.

Even with relatively high demand, such a gigantic supply has kept the AK fairly cheap for terrorists, drug lords, and thugs around the globe. In fact, in some places an AK-47 is actually much cheaper today than it was 25 years ago. In a 2005 interview about his book Illicit, editor Moises Naim of Foreign Policy relayed an anecdote about a Kenyan village in which an AK-47 cost 15 cows in 1986. Nineteen years later the price had cratered to just four cows. In Killicoat’s “Weaponomics” paper he breaks down average AK-47 prices by region, and while most run buyers a few hundred dollars, he tracked transactions for as little as $40 or $50.

So Mikhail Kalashnikov must be pretty rich, right?

Think again. The Soviet government wasn’t exactly generous with its royalty payment on his rifles. Kalashnikov has confirmed that he never made a cent in royalties off of his gun design since the government simply took the plans and mass-produced the rifle. Kalashnikov reportedly lives modestly off of his government pension. He's lent his name to several other products, including Kalashnikov Vodka, which was launched in 2004.

Kalashnikov actually comes across as a deeply conflicted inventor in interviews and public statements. He’s obviously very proud of having designed a workhorse rifle that served the Russian military for so long, but he’s uneasy about the role the gun has assumed in terrorist culture. At the same time, he realizes that he’s not to blame for the AK-47 ending up in the wrong hands. At a celebration of his 90th birthday, he said, ''I created a weapon to defend the borders of my motherland. It's not my fault that it's being used where it shouldn't be.”

On a 2002 visit to Germany, Kalashnikov expressed similar ambivalence, saying, “I'm proud of my invention, but I'm sad that it is used by terrorists. I would prefer to have invented a machine that people could use and that would help farmers with their work—for example a lawnmower."

Is it Legal to Own an AK-47 in the United States?

Short answer: if you’re talking about a legitimately fully automatic AK-47, only in rare cases. While it’s no longer legal for domestic companies to make or import machine guns for civilian use, private individuals can still lawfully own machine guns that were legally registered prior to May 1986. These grandfathered-in guns (including some AK-47s) can legally be transferred to new owners, but it’s a tightly regulated transaction overseen by the ATF. It’s also pricey; in addition to all the background checks and oversight the transfer usually includes a $200 excise tax.

Semi-automatic look-alikes (that is, rifles where you have to pull the trigger each time you want to fire a shot) are legal in many areas, though. Some enterprising companies have used this fact to their advantage. In 2009 Max Motors of Butler, MO ran a “Free AK-47 with Any New Truck” promotion.

Man Buys Two Metric Tons of LEGO Bricks; Sorts Them Via Machine Learning
May 21, 2017

Jacques Mattheij made a small, but awesome, mistake. He went on eBay one evening and bid on a bunch of bulk LEGO brick auctions, then went to sleep. Upon waking, he discovered that he was the high bidder on many, and was now the proud owner of two tons of LEGO bricks. (This is about 4400 pounds.) He wrote, "[L]esson 1: if you win almost all bids you are bidding too high."

Mattheij had noticed that bulk, unsorted bricks sell for something like €10/kilogram, whereas sets are roughly €40/kg and rare parts go for up to €100/kg. Much of the value of the bricks is in their sorting. If he could reduce the entropy of these bins of unsorted bricks, he could make a tidy profit. While many people do this work by hand, the problem is enormous—just the kind of challenge for a computer. Mattheij writes:

There are 38000+ shapes and there are 100+ possible shades of color (you can roughly tell how old someone is by asking them what lego colors they remember from their youth).

In the following months, Mattheij built a proof-of-concept sorting system using, of course, LEGO. He broke the problem down into a series of sub-problems (including "feeding LEGO reliably from a hopper is surprisingly hard," one of those facts of nature that will stymie even the best system design). After tinkering with the prototype at length, he expanded the system to a surprisingly complex system of conveyer belts (powered by a home treadmill), various pieces of cabinetry, and "copious quantities of crazy glue."

Here's a video showing the current system running at low speed:

The key part of the system was running the bricks past a camera paired with a computer running a neural net-based image classifier. That allows the computer (when sufficiently trained on brick images) to recognize bricks and thus categorize them by color, shape, or other parameters. Remember that as bricks pass by, they can be in any orientation, can be dirty, can even be stuck to other pieces. So having a flexible software system is key to recognizing—in a fraction of a second—what a given brick is, in order to sort it out. When a match is found, a jet of compressed air pops the piece off the conveyer belt and into a waiting bin.

After much experimentation, Mattheij rewrote the software (several times in fact) to accomplish a variety of basic tasks. At its core, the system takes images from a webcam and feeds them to a neural network to do the classification. Of course, the neural net needs to be "trained" by showing it lots of images, and telling it what those images represent. Mattheij's breakthrough was allowing the machine to effectively train itself, with guidance: Running pieces through allows the system to take its own photos, make a guess, and build on that guess. As long as Mattheij corrects the incorrect guesses, he ends up with a decent (and self-reinforcing) corpus of training data. As the machine continues running, it can rack up more training, allowing it to recognize a broad variety of pieces on the fly.

Here's another video, focusing on how the pieces move on conveyer belts (running at slow speed so puny humans can follow). You can also see the air jets in action:

In an email interview, Mattheij told Mental Floss that the system currently sorts LEGO bricks into more than 50 categories. It can also be run in a color-sorting mode to bin the parts across 12 color groups. (Thus at present you'd likely do a two-pass sort on the bricks: once for shape, then a separate pass for color.) He continues to refine the system, with a focus on making its recognition abilities faster. At some point down the line, he plans to make the software portion open source. You're on your own as far as building conveyer belts, bins, and so forth.

Check out Mattheij's writeup in two parts for more information. It starts with an overview of the story, followed up with a deep dive on the software. He's also tweeting about the project (among other things). And if you look around a bit, you'll find bulk LEGO brick auctions online—it's definitely a thing!

What Happened to Jamie and Aurelia From Love Actually?
May 26, 2017

Fans of the romantic-comedy Love Actually recently got a bonus reunion in the form of Red Nose Day Actually, a short charity special that gave audiences a peek at where their favorite characters ended up almost 15 years later.

One of the most improbable pairings from the original film was between Jamie (Colin Firth) and Aurelia (Lúcia Moniz), who fell in love despite almost no shared vocabulary. Jamie is English, and Aurelia is Portuguese, and they know just enough of each other’s native tongues for Jamie to propose and Aurelia to accept.

A decade and a half on, they have both improved their knowledge of each other’s languages—if not perfectly, in Jamie’s case. But apparently, their love is much stronger than his grasp on Portuguese grammar, because they’ve got three bilingual kids and another on the way. (And still enjoy having important romantic moments in the car.)

In 2015, Love Actually script editor Emma Freud revealed via Twitter what happened between Karen and Harry (Emma Thompson and Alan Rickman, who passed away last year). Most of the other couples get happy endings in the short—even if Hugh Grant's character hasn't gotten any better at dancing.
