11 Geeky Snow Creations We Love

Original image
Reddit User spmm

Whether snowmen, snow sculptures, or something that lands strangely in the middle, these snow structures are some of the most delightfully geeky ones out there.

1. Won't You Be My Neighbor?

I can’t tell you who actually made this incredible and adorable Totoro snowman, but I can tell you that it was featured on the Hayao Miyazaki Fan Page and that if a magical hat could bring any snow creation to life, I would hope it was this one. After all, who doesn’t want to play with their very own Totoro?

2. The Doctor is In

When it came time to create a snowy version of the Time Lord, Flickr user Great Beyond went with the Tom Baker version.

3. It's Bigger (And Warmer) On the Inside

If you're at all familiar with Whovians, you know that they'll make a TARDIS out of anything, including snow—like this one by DeviantArt user facethecookie.

4. Masters of the Snowiverse

Why build an igloo to huddle in when you can ask Kilroy III if he can make you a Castle Grayskull like this one, which comes complete with two full wings and a seat in each wing.

5. Hoth in Here

Look seriously awesome while sitting on some snow by building an incredible AT-AT sculpture like this one by Redditor bluebomber.

6. Snow Slug

On the other hand, if you want an excuse to force someone to sit in the snow in a gold bikini, Twitter user Fetts has got you covered. Best of all, this Jabba seems to be lifesize and appropriately colored.

7. The Droid You're Looking For

For those Star Wars fans who want to keep their snow sculptures fighting on the side of good and not evil, Jen C has set a more positive example with her delightful R2-D2 sculpture.

8. Return of the Snowman

When vandals knock over your snowman, get creative like this Redditor, who took advantage of his destroyed Gandalf the Gray by resurrecting the snowman into Gandalf the White.

9. Weapon of Icy Destruction

Another good solution to this problem involves creating snowmen that are already being destroyed and suffering, like those young Calvin of Calvin and Hobbes was known to make. Neighborhood vandals sure aren’t going to have as much fun destroying a snowman that’s already been slaughtered by an icicle like the one in this sad scene by Flickr user Pahz.

10. Who You Gonna Call?

Just a few pieces of fabric can make a huge difference when it comes to the personality of your snowman. After all, without the hat and neck piece, Redditor spmm’s Stay Puft Marshmallow Man would look more like the Michelin Man. But those few accessories made him the delightfully goofy monster we all loved in Ghostbusters.

11. Fun with ... Fungus

If you don’t feel comfortable in cold weather or just aren’t very good at sculpting, you can always try making your snowmen out of other materials. Fungus, for example, worked rather well for the team over at the J. Craig Venter Institute.

Well Flossers, now it’s your turn. If you’ve made any great geeky snow sculptures of your own, feel free to share the pictures or stories of the creation in the comments section. I wish I could join in the fun, but living in San Diego means snowmen aren’t my strong suit.

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

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!

Here's How to Change Your Name on Facebook

Whether you want to change your legal name, adopt a new nickname, or simply reinvent your online persona, it's helpful to know the process of resetting your name on Facebook. The social media site isn't a fan of fake accounts, and as a result changing your name is a little more complicated than updating your profile picture or relationship status. Luckily, Daily Dot laid out the steps.

Start by going to the blue bar at the top of the page in desktop view and clicking the down arrow to the far right. From here, go to Settings. This should take you to the General Account Settings page. Find your name as it appears on your profile and click the Edit link to the right of it. Now, you can input your preferred first and last name, and if you’d like, your middle name.

The steps are similar in Facebook mobile. To find Settings, tap the More option in the bottom right corner. Go to Account Settings, then General, then hit your name to change it.

Whatever you type should adhere to Facebook's guidelines, which prohibit symbols, numbers, unusual capitalization, and honorifics like Mr., Ms., and Dr. Before landing on a name, make sure you’re ready to commit to it: Facebook won’t let you update it again for 60 days. If you aren’t happy with these restrictions, adding a secondary name or a name pronunciation might better suit your needs. You can do this by going to the Details About You heading under the About page of your profile.
