An Open Letter to Brad Marchand

http://ift.tt/2kDIRON

Brad,

It wasn’t too long ago that you were establishing yourself as an NHL-caliber player. After proving to the Bruins organization that you had a special offensive prowess with Providence in 2008 and 2009, the team decided it would be best to give you a shot with the NHL club. Your first season with the varsity squad would certainly be a memorable one.

In 77 games with the Bruins, you notched 41 points, solidifying your spot on a very competitive roster. In your first taste of the playoffs, you brought your A-game. In 25 playoff games, you scored 11 goals, ten of which were at even strength, and tacked on eight assists. Oh, and you finished it off by lifting Lord Stanley’s Cup above your head as a rookie. Not a bad way to kick off your NHL career.

Two-Way Talent

Since then, you’ve established yourself as a core player for the organization. Your offensive abilities have taken off, leading you to a career-high 61 points last season. You have a natural knack for finding the back of the net; your 14.93 career shooting percentage is third among all active players, ahead of guys like Sidney Crosby.

Meanwhile, you’ve polished your defensive game to become a top of the line two-way forward (that’s what happens when you sit on Patrice Bergeron’s wing for years, right?). You’ve now become a premier NHL player, one that Claude Julien can throw out to score a game-winning goal, or to kill off the biggest penalty of the game.

However, as you’ve developed into one of the most valuable players in Boston, one question mark has anchored you down – discipline.

Playing with an Edge

Look, I understand the type of game you play. You broke into the league as a scrappy forward, and you’re one of the best in the league when it comes to getting under the opposition’s skin. That’s all great. You’ve found a very specific niche to identify with, and it’s led you to quite a bit of success so far.

But the line that you walk is a very thin one, and you too often find yourself on the wrong side of it. Let’s look at your track record for a moment.

A few years ago, when the antics really started to emerge, you were a hot-topic in the Boston media. With the organization falling from its place of grace, and trade rumors flying around, people began questioning whether your talent was worth the lack of discipline on the ice.

And then, something kind of cool happened. A new Marchand walked into the doors of training camp prior to last season. The news reports were pleasantly surprised to see an extra jump in your step, and you made it very clear that you wanted to serve as a leader for a club that you had long-since established a prominent role with. Maybe you had taken the media’s speculation to heart. Maybe you decided on your own that it was time to mature your game a bit. There’s only one person who knows that, and it’s you.

Either way, Bruins fans were impressed with the guy in 63 last season. You took on a leadership role of sorts for the team and posted the best numbers of your career. But at the end of the season, there was one dark spot – the unnecessary low hit you made on Mark Borowiecki of the Senators.

Since then, things have been a bit better. We’ve spent more time celebrating your goals, and less time cringing about iffy plays. I, like some fellow writers that I know, would even have gone so far as to say that you recognized your value to the team, and put those kinds of things behind you.

And then the calendar turned to 2017. Already in 2017, we’ve seen a couple of plays that were pretty unreasonable. There was the trip on Niklas Kronwall that cost you $10,000 on January 24th, and then a similar incident a week later in Tampa Bay.

Long story short, your play hasn’t matured as much as we thought it did, and that’s an issue. To put it bluntly, you’re just too important to this Bruins team to risk taking yourself out of the lineup with those types of plays.

A Plea for the Future

Look around the locker room. You aren’t a rookie anymore. You’re in the middle of your seventh full season with the Bruins. You’re the team’s top producer, you just earned your way to the first All-Star Game of your career, and you’re a guy that younger players can look up to. You’ve become a top-flight two-way forward while developing one of the best scoring touches in the game.

But all of that gets ruined when you slew-foot somebody. When you cross the line, you negate the skill that you’ve spent your entire life building, and more importantly, you severely hurt the team that you’ve represented your entire career.

I’ll sum it up like this. Playing with an edge is fine. When you do it the correct way, you’re better than anybody at being the under-your-skin producer. That’s why former President Barack Obama called you “the Little Ball of Hate” during that White House visit six years ago. But you have to recognize that you’re dancing on a very thin line, and the city of Boston needs you to remain on the correct side of it. Play the game the way you do best. Just do it right.

Sincerely,

Concerned Bruins fans everywhere.

In Just 5 Moves, Grandmaster Loses and Leaves Chess World Aghast

Here's an abridged list of phrases you might not expect to be spoken in anguish by a chess play-by-play announcer:

  • "What's going on? What the hell is going on? What. Is. Going. On??"
  • "Has she gone mental?"
  • "I've done this kind of bet when I've been extremely drunk with my friends. ... This is the kind of thing you'd see in a primary school or from a very drunk person."

And yet, here was British grandmaster Simon Williams, uttering his astonishment as the women's chess world champion effectively threw her match in just five baffling moves at the Tradewise Gibraltar Chess Festival.

Hou Yifan, a Chinese grandmaster so accomplished she's earned the nickname "Queen of Chess," turned her skills against herself spectacularly in her 10th and final match at the event. Her loss to India's Lalith Babu was so decisive, in fact, that it begged explanation.

After the match, Hou offered one freely: She was "really, really upset" for the "unbelievable and weird pairings" that meant seven of her 10 opponents during the event were women.

Hou, who currently outpaces the second-ranked female player by 68 points, recently left the women's chess circuit for mixed events where she can compete against men, who fill every spot in the world's top 100 rankings.

"It would allow me to focus on the top level, on the 'men's' field," Hou told ChessBase magazine of her decision last year. "I could try to become stronger, to be more efficient, as there would be no obligation to play the women's tournaments anymore."

When she found herself competing against other female players in the lion's share of matches at Gibraltar, Hou was frustrated. In her post-match interview, she says she brought her concerns to the event's "chief arbiter" on Tuesday, to no avail.

So she decided on a very public display of protest: throwing her final match.

"I just hoped that attention could be coming to the final decisive round," Hou said. "And what I also hope [is] that the pairings — you know — for the future event should be like a 100 percent fair situation."

And she certainly drew attention: Besides the flabbergasted Simon Williams, the festival's tournament director, Stuart Conquest, called Hou's game the "biggest crisis" in the festival's history, according to The Telegraph.

Brian Callaghan, the festival's organizer, was nonplussed. He says the matchup drawings "come out of machines," dismissing allegations of any intentional unfairness.

"These pairings are not made by people," Callaghan said Thursday. "I understand: If I was in her shoes, and I suddenly pulled a draw of six girls one after the other, I would say also, 'What is going on here?' But clearly nothing was going on. It's coming out of a machine."

Callaghan said Hou is still "very popular with me and very popular with the tournament," but also added: "I'm sorry for Yifan, because I think she let herself down a little bit today."

Greenlight Capital's Q4 Letter: Dramatically Increased General Motors Position

http://ift.tt/2l1fxOR

David Einhorn's hedge fund Greenlight Capital finished 2016 up 8.4% and has returned 16.1% annualized since inception in 1996.

Their fourth quarter letter examines how their portfolio is positioned now that Donald Trump is president and will be trying to change policies. 

Greenlight is long various US value stocks that could benefit from corporate tax cuts (AMERCO, CC, Dillard's, DSW), they're long companies that can benefit from repatriation of foreign cash (Apple (AAPL)), and they're long companies that can benefit from demand for consumer durables (General Motors (GM), a position in which they've "dramatically increased their position."

They're also short 'bubble basket' stocks (Netflix), oil frackers, and Caterpillar (CAT).

Turning back to their thesis on GM, Greenlight writes that, "While the bears have been screaming 'peak auto' for the last couple of years, we think a strengthening job market will sustain the current upcycle and lead to better than expected credit performance at GM's finance subsidiary.  While the bears also cite long-term concerns over self-driving cars, we see a huge intermediate-term opportunity in assisted-driving cars."

During the quarter, David Einhorn's firm also exited its positions in AECOM (ACM), Michael Kors (KORS), and Take-Two Interactive Software (TTWO).   They also covered short positions in FLSmidth (Denmark: FLS), Mead Johnson Nutrition (MJN), and Reynolds American (RAI).

At the end of 2016, their largest positions in alphabetical order were: AerCap, Apple, CONSOL Energy, General Motors, and gold.  Their average exposures were 106% long and 81% short.

Facebook's Oculus lost a case against game maker ZeniMax, leaving the tech company on the hook for $500 million.

A jury ordered Facebook to pay $500 million in damages to ZeniMax due to theft of intellectual property on Wednesday.

ZeniMax sued Oculus for allegedly stealing its intellectual property. The company claimed Oculus' VR device Oculus Rift was "primitive" until John Carmack, Oculus chief technology officer and founder of a company owned by ZeniMax, improved on the device using his knowledge from his previous work as a ZeniMax employee. It also said that Oculus founder Palmer Luckey "commercially exploited" Zenimax computer code and trade secrets in order to develop its products.

Facebook purchased Oculus in 2014. Facebook CEO Mark Zuckerberg testified in court that he was not aware of the intellectual property claims between Oculus and ZeniMax.

The WHOOP Approach to Measuring Sleep

http://ift.tt/2jxvU9O

The Technology

WHOOP measures blood flow using a technology called Photoplethysmography (PPG). There are LEDs (light-emitting diodes) on the bottom of the strap that shine light into your skin, which is full of tiny capillaries. Blood in the capillaries absorbs more of the light than the tissue surrounding it. Specifically, the hemoglobins in blood absorb a particular wavelength of light. The light that isn’t absorbed is reflected back and received by a sensor called a photodiode, which is located between the LEDs. By observing the differences in light, WHOOP is able to track the changes in blood flow caused by each pulse, and in turn calculate your heart rate and heart rate variability.

The WHOOP Strap also contains a three-axis accelerometer that measures motion. The PPG and accelerometer data are plugged into an advanced algorithm that determines your sleep stages (for a deeper dive into the stages of sleep, take a look at the White Paper: The Importance of Sleep Stage Tracking for Athletic Performance and Recovery). Unfortunately the algorithm is a trade secret, so we can’t get into the specifics of how it works. However, we can tell you about the process that went into creating it.

 

Sleep Testing

About two years ago, WHOOP began running sleep tests on a wide variety of subjects. Among the early participants were company employees, college athletes, a Boston running running club and other local volunteers.

Each subject visited a certified sleep lab and underwent an overnight sleep test known as a polysomnogram (PSG). Participants were instructed to do everything as they normally would leading up to the study. At the lab, they were each given a room to sleep for the night that resembled a boring hotel room. The rooms were dark, comfortable and optimized for ideal sleep temperature. Many subjects brought work, while others read books and watched movies before falling asleep.

The participants were outfitted with WHOOP Straps and numerous electrodes from the neck up to collect data for the PSG (pictured below via infrared video). They were then monitored by certified sleep technicians in an adjacent room for the entire night.

Screen Shot 2017-01-25 at 3.49.04 PM

WHOOP data scientists trained our sleep staging algorithm by lining up the results of the PSGs with the data from the WHOOP Straps. 

We’ve followed this format ever since, refining and improving the algorithm as more and more athletes have gone through our sleep study protocol. Each time the Strap’s hardware or signal processing technology has been updated, more testing has been done to ensure the continued accuracy of the algorithm’s sleep detection.

 

WHOOP and You

No two human bodies are alike. From the minute you put on a WHOOP Strap, it begins to learn specifically about you. The algorithm is constantly running and collecting data 24/7. After examining your first night’s Sleep wearing the Strap, WHOOP analyzes the data and uses it to better understand your body going forward.
