The LeBron James Sweepstakes

Original image

These are anxious times in the city of Cleveland where a downtown banner in honor of two-time NBA Most Valuable Player LeBron James proclaims, "Born Here. Raised Here. Plays Here. Stays Here."

In most cases, three out of four is seen as a winning percentage. (I know I would've glady accepted that as a batting average while asking girls out back in high school as opposed to the school record hitless streak I preserved through graduation.)

But whether James stays in Cleveland with July 1 free agency approaching is a complete game changer in the mental health of a dedicated, reinvigorated but still mostly hapless sports town.

Taking down the "Born here" banner is the least of it. Having to use it to break falls from high ledges -- fireman rescue style -- is a possibility if LeBron bolts.

Only the Cavaliers can talk to James between now and July. NBA rules allow teams to pay more than other suitors to keep their own superstars. Yet, James' announced intention to "go through the process" and his track record of flirting with New York is the cause of much trepidation and -- at the very least -- downgrades the banner declarative to a question:

Stays Here?

Musical Chairs (Really Expensive Ones)

James, Miami's Dwyane Wade and Toronto's Chris Bosh are friends and Olympic teammates who orchestrated their free agencies to coincide, thereby raising the volume and increasing the tempo in this game of high-stakes musical chairs.

In part for that reason, this is like no other free agency. Baseball, still without a salary cap all these years later, most often produces the free-agent buzz. Alex Rodriguez signed with Texas for $252 million over 10 years. Long before him, Pete Rose made the one of the first ego-inflating "free agent tours" in 1978.

Only in basketball, though, can one superstar change the fortunes of a franchise so quickly. And James is launching himself into those waters at the height of his game and at the still precocious age of 25.


Forbes magazine estimates that the Cavaliers franchise was worth approximately $250 million the year before James came out of high school in Akron, Ohio, and went to work 30 miles north. This past season, in which every home game was sold out, the magazine estimated owner Dan Gilbert's investment at $476 million.


The stakes in part explain why Ohio Gov. Ted Strickland recently stopped in town to join a chorus of local celebrities and politicians in serenading James in a "Please Stay LeBron" video to the tune of "We Are The World."

Strickland defended taking time out of his busy schedule, telling reporters, "Come on, this is economic development. Do you know how important this is to the state of Ohio? LeBron means a lot to the future of our state."

Comedian Mike Polk came up with the idea for the video. His previous Cleveland tourism videos were outrageously funny, though some city officials didn't see the humor. Maybe some of the lyrics -- "Buy a home for the price of a VCR" -- had something to do with it. So, too, the battle cry sign-off of "We're not Detroit!"

The LeBron video was likewise done for comic relief. Some outsiders took it seriously. (I mean, folks, really now. We know "We Are The World" was originally used to raise awareness about world hunger. That's the joke.)

Polk put a famous-in-Cleveland furniture salesman and a personal injury lawyer on the same stage with the Governor and had a U.S. Senator (Sherrod Brown) pipe in on a remote feed. The lyrics offer to name every street in the city after James.

Which, of course, is ridiculous. Too costly. They'd just change the town name to LeBronland.

The LeBron-O-Meter

On the subject of things LeBron, the website partner of the newspaper I work for, The Plain Dealer, began running a daily LeBron-O-Meter offering a daily measurement (do I need to say "unscientific"?) of this period of transition.

Depending on the news or rumor of the day, the LeBron-O-Meter needle can settle into any one of five areas:


Staying.


Looking Good.


Keep 'em Guessing.


Uh-Oh.


Gone.

(It strikes me that given the divorce rate in 2010, this could be a handy tool for marriage counselors to give couples to better help them deal with issues as they arise.)

Everywhere the people of Cleveland look these days they find other women flirting with their beau and third parties sticking their noses in and adding to the stress.

His Many Suitors


From New York, Mayor Michael Bloomberg says he wants James to know what a great place his town is to raise kids. (James has two children.)


On behalf of Chicago, President Obama told Marv Albert in a recent interview that the Bulls would be a "great fit" for James.


Cleveland Browns' great Jim Brown says James will leave because Cavaliers fans were so harsh in their criticism of him after the team's surprising second round loss to the Boston Celtics.

The same day, author Buzz Bissinger, who did a book on James and his high school teammates, said James probably should leave for the benefit of his emotional development because Cleveland fans have coddled him too much.

In Dallas, Mavericks owner Mark Cuban was fined $100,000 by the NBA for saying the obvious -- the Mavs would be interested in James if he chooses not to stay in Cleveland.

In Los Angeles, 75 fans of the Clippers staged a parade around Staples Center last Thursday to show James how much they want him. That's impressive. I mean, who knew the Clippers had 75 fans and that they'd know how to stage a parade?

Not to be outdone, a 23-year-old transplanted Clevelander by the name of Brandon George, is intent on making James understand how important it is that he stay in Cleveland.

So George, who lives in Atlanta, waxed his chest.

Then he brushed his teeth with Dave's Insanity Hot Sauce.

I don't know the state of his list, but at that point he had 21 other self-tortures planned. Twenty three in all to match James' jersey number.

George started inlebronwetrust.com. Similar sites have cropped up on behalf of other fan bases. There are at least 67 Facebook groups dedicated to bringing James to New York.

His free agent tour can start on July 1. It'll be the recruiting period he never had as a high school senior, seeing as how every college recruiter knew it would be a waste of time since James long planned to go right from high school to the NBA.

With the NBA keeping an eagle's eye out for tampering with other teams' players ahead of the July 1 date, no organization is even hinting at how it will go about enticing James. Only a handful of teams have the salary cap flexibility to sign a superstar looking for a max contract.

Recruiting Pete Rose

Coincidentally, one of the first free agent tours also involved a hometown guy facing the prospect of leaving his local team -- the aforementioned Pete Rose in 1978.

What I remember about that first ego trip was that Rose appeared to be wearing Zsa Zsa Gabor's fur coat.

Atlanta, Kansas City, St. Louis, Pittsburgh and Philadelphia were among those who declared interest in Rose as part of a free agent re-entry draft back then.

Rose chartered a Lear jet and showed up places wearing a $4,000 mink coat. Earlier in the 1978 season, the Reds had asked Rose to stop driving his Rolls Royce to the park because it "made the fans mad." Rose refused.

He took two things on the trip. His agent, Reuven Katz, was one.

The other was a 25-minute video tape of his highlights.

Rose had already won it all with the Big Red Machine. He'd chased Joe DiMaggio's 56-game record hit streak. And he needed a video?

In Atlanta, Ted Turner offered him $1 million a year while he played and $100,000 a year for life in retirement.

In Kansas City, Kaufmann offered him a four-year deal and an oil investment.

Augie Busch in St. Louis offered a beer distributorship.

The Galbreath family in Pittsburgh, which owned Dandy Don Farms, were willing to cut him into the thoroughbred biz.

When Rose accepted a four-year deal in Philadelphia, he left money on the table but wasn't worried.

Of his four-year, $3.2 million contract, Rose said, "You could stack it all up and a show dog couldn't jump over it."

Keep 'em guessing

NBA rules prohibit teams from circumventing the salary cap these days. Like Rose choosing the Phillies because he felt they gave him the best chance to win a World Series, James says his decision will be all about the opportunity to win championships.

When he accepted his second consecutive MVP award during the Boston series, he staged the ceremony at the University of Akron basketball arena where he played many games as a high schooler. His family and friends and teammates all joined him.

Looking at the scene that that day, you couldn't help but think that it would take something extraordinary to extract James from his comfort zone in Northeast Ohio, what with the Cavaliers on the verge of a title.

Someone asked him about that in not those exact words.

"Wherever I go, Akron will always be my home," he said.

On the LeBron-O-Meter, that was "Keep 'em guessing."

Then the Cavs lost three straight to the Celtics and the series.

That put Cleveland fans in "Uh-oh" land.

The LeBron Sweepstakes

Cleveland Cavaliers

Pluses: The Cavs can offer James more money. If he signs a three-year deal, which is the conventional thought, he could make $9 or $10 million more simply by staying. Cavaliers' owner, Dan Gilbert, has spared no expense in trying to build a winner around James. His mother, long-time girlfriend and children are already here. Head coach unsettled after the firing of Mike Brown. But James could have a say in his successor. In a CNN interview with Larry King, James said that Cleveland "absolutely" had an advantage over his other suitors.

Minuses: The Cavs' roster may take a year or more to overhaul and they've lost salary cap flexibility in chasing a title. James may feel a bigger market would help sell him as a brand. He may simply be ready for a change of scenery.

New York Knicks

Pluses: James loves New York and Madison Square Garden as a stage. If you can make it there, you can make...oh, sorry, that's a song I had stuck in my head. The Knicks have the cap room to potentially add James and, say, Toronto's Chris Bosh.

Minuses: The Knicks roster. If they spend on James and Bosh, the rest of their team will be made up of players making the minimum. That's not a recipe for a championship.

New Jersey Nets

Pluses: Some good young players. A new arena in Brooklyn in the works. Well-heeled new ownership in Russian Mikhail Prokhorov. James' friendship with Jay-Z, a Nets' part owner.

Minuses: It's the Nets, not the Knicks. It's not Manhattan. The Nets aren't close to winning.

Chicago Bulls

Pluses: Point guard Derrick Rose and Joakim Noah. James grew up a Michael Jordan fan. He switched his number from 23 to 6 for next year in honor of Jordan.

Minuses: Not the kind of ownership James has enjoyed in Cleveland. Head coach unsettled. Living up to the Jordan legacy would be next to impossible.

Miami Heat

Pluses: The Heat have the flexibility to add another superstar. James could team up with Dwyane Wade, who has already won a title. A Hall of Fame coach, Pat Riley, is already in the organization. Florida is tax friendly for athletes. The weather can't be discounted.

Minuses: NBA rules only allow teams to play with one ball at a time. Who gets it with the game on the line, James or Wade? James is a better distributor of the basketball but James and Wade are too similar to truly complement each other.

Los Angeles Clippers

Pluses: They have cap flexibility. And talent.
Minuses: They're the Clippers. Donald Sterling is still their owner. James would play second fiddle to Kobe Bryant in L.A.

Man Buys Two Metric Tons of LEGO Bricks; Sorts Them Via Machine Learning
Original image
iStock // Ekaterina Minaeva

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!

Why Your iPhone Doesn't Always Show You the 'Decline Call' Button
Original image

When you get an incoming call to your iPhone, the options that light up your screen aren't always the same. Sometimes you have the option to decline a call, and sometimes you only see a slider that allows you to answer, without an option to send the caller straight to voicemail. Why the difference?

A while back, Business Insider tracked down the answer to this conundrum of modern communication, and the answer turns out to be fairly simple.

If you get a call while your phone is locked, you’ll see the "slide to answer" button. In order to decline the call, you have to double-tap the power button on the top of the phone.

If your phone is unlocked, however, the screen that appears during an incoming call is different. You’ll see the two buttons, "accept" or "decline."

Either way, you get the options to set a reminder to call that person back or to immediately send them a text message. ("Dad, stop calling me at work, it’s 9 a.m.!")
