12 Attempts to Bribe Celebrities for Worthy Causes

Original image

Want to contribute to a worthy cause and get your favorite celebrity to do something awesome and/or ridiculous? That’s the idea behind Charity Bribes.

Anyone can post something awesome or bizarre for a specific celebrity to do. These ideas go on a master list, where the good people of the Internet vote for their favorites. Currently on the leader board: “Morgan Freeman to spend an afternoon narrating user-submitted animal videos.”

The activity with the most votes when the current bribe expires (every 30 days) is the next one to be featured. People then pledge money to get the celeb to do the aforementioned awesome thing. If the celeb doesn’t take the bribe, no one has to give the money they pledged. If the celebrity follows through, the predetermined charity gets the cash that was raised.

Larry David fans recently pledged more than $10,000 in an attempt to get LD on Twitter. Larry hasn't reacted to the bribe yet, but he has 30 days from the end of the bribe to make good on the deal. I have a good feeling about the current bribe, which happens to be #1 on our list:

1. Get Conan O’Brien to interview a guest on his show wearing an eye patch and black turtleneck while holding a pipe. If asked why, he should say, “I don’t want to talk about it.” All proceeds from this bribe go to Autism Speaks.

2. Get Christopher Walken to read dramatically from an upper-level biochemistry textbook. Perhaps adding in relevant anecdotes about his life. Proceeds go to The Sierra Club.

3. Get Celine Dion to sing “I Want Your Sex” by George Michael. Proceeds go to Cystic Fibrosis Quebec.

4. Get Rachael Ray to do a show with Epic Meal Time and each has to make the other's dish according to their recipe and instructions. Proceeds go to the American Heart Association.

5. Get Donald Trump to post a picture of how his hair looks when he wakes up. Proceeds go to St. Jude’s Children’s Hospital.

6. Get the Cast of the Wonder Years to reenact a famous scene. Proceeds go to United Way of NY.

7. Get Bill Clinton to do the Icky Shuffle and the Hokey Pokey on video. Proceeds go to the Clinton Global Initiative. (I feel like this probably happens at wedding receptions all of the time.)

8. Get Daniel Day Lewis to post a YouTube video of him reenacting the milkshake scene from There Will Be Blood with an eight year old drinking an actual milkshake. Proceeds go to AIDS. (I’m assuming that means the AIDS Foundation, but the user doesn't actually say).

9. Get Jack Black and Jack White to sing the hit song "Ebony and Ivory". Proceeds go to Little Kids Rock.

10. Get Katy Perry to switch places with Zooey Deschanel for a WHOLE episode of New Girl where no one acknowledges the switch. Proceeds go to Trevor Project.

11. Get Jeff Bridges to anchor ABC World News. Proceeds go to No Kid Hungry.

12. Get Christopher Lloyd to take a video of himself reenacting a scene from Back to the Future where he says "Great Scott!" Proceeds go to the Michael J. Fox Foundation for Parkinson's Research.

Let us know if you post a bribe. Anyone want to see Mangesh and Will arm wrestle? Want Ransom to give your town the Strange Geographies treatment?

Man Buys Two Metric Tons of LEGO Bricks; Sorts Them Via Machine Learning

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!

Working Nights Could Keep Your Body from Healing

The world we know today relies on millions of people getting up at sundown to go put in a shift on the highway, at the factory, or in the hospital. But the human body was not designed for nocturnal living. Scientists writing in the journal Occupational & Environmental Medicine say working nights could even prevent our bodies from healing damaged DNA.

It’s not as though anybody’s arguing that working in the dark and sleeping during the day is good for us. Previous studies have linked night work and rotating shifts to increased risks for heart disease, diabetes, weight gain, and car accidents. In 2007, the World Health Organization declared night work “probably or possibly carcinogenic.”

So while we know that flipping our natural sleep/wake schedule on its head can be harmful, we don’t completely know why. Some scientists, including the authors of the current paper, think hormones have something to do with it. They’ve been exploring the physiological effects of shift work on the body for years.

For one previous study, they measured workers’ levels of 8-OH-dG, which is a chemical byproduct of the DNA repair process. (All day long, we bruise and ding our DNA. At night, it should fix itself.) They found that people who slept at night had higher levels of 8-OH-dG in their urine than day sleepers, which suggests that their bodies were healing more damage.

The researchers wondered if the differing 8-OH-dG levels could be somehow related to the hormone melatonin, which helps regulate our body clocks. They went back to the archived urine from the first study and identified 50 workers whose melatonin levels differed drastically between night-sleeping and day-sleeping days. They then tested those workers’ samples for 8-OH-dG.

The difference between the two sleeping periods was dramatic. During sleep on the day before working a night shift, workers produced only 20 percent as much 8-OH-dG as they did when sleeping at night.

"This likely reflects a reduced capacity to repair oxidative DNA damage due to insufficient levels of melatonin,” the authors write, “and may result in cells harbouring higher levels of DNA damage."

DNA damage is considered one of the most fundamental causes of cancer.

Lead author Parveen Bhatti says it’s possible that taking melatonin supplements could help, but it’s still too soon to tell. This was a very small study, the participants were all white, and the researchers didn't control for lifestyle-related variables like what the workers ate.

“In the meantime,” Bhatti told Mental Floss, “shift workers should remain vigilant about following current health guidelines, such as not smoking, eating a balanced diet and getting plenty of sleep and exercise.”
