The poem above is old, but the sentiment is universal. I first saw the verse at Plinko's error page, but the original author is nowhere to be found, although the verse owes a lot to Edgar Allan Poe. Looking for something on the internet that leads to an error page is frustrating, but there's an art to alleviating the reader's pain. Only this, and nothing more. Some websites make their 404 page entertaining in itself, and a few make it a real treat. You might even be distracted from what you were trying to find in the first place!

The Internet Movie Database (IMDb) is all about movies, so it makes sense that their error page gives you a well-known quote about your situation. There are about a dozen quotes that rotate, with some exact quotes, and some that are altered for the occasion.

BedMap is a hotel finder. They also found a great movie quote to adapt for their error page.

The Association for Computing Machinery's error page talks to you in text. The message goes on way after what you see here, until you feel much sorrier for the poor web server than you feel for yourself.

The error page at the game Brain Chef does the same thing as ACM, but instead of becoming melancholy, it flirts with you! And it keeps on, trying to keep you from navigating elsewhere.

The 404 page at Everlasting Blort acknowledges that the server is just as confused as you are. The page contains a flashing .gif that may trigger reactions if you suffer from photosensitive epilepsy. Those who visit Blort often already know that disorientation is what you go there for in the first place.

NPR's error page looks pretty normal for National Public Radio, but it cleverly contains a list of other things besides your missing destination link that cannot be found. After Amelia Earhart and the erased Watergate tape, they list Jimmy Hoffa, your luggage, Atlantis, and Waldo. Each item links to an article about the subject.

Homestar Runner blames you for the error. Which is just as well- I blame them for not adding anything new for years. Still, if you haven't seen all the cartoons, they are there for your enjoyment. But the other error messages they've used over the years were memorable as well.

Lesson learned: don't ever cram a Swiss cake roll into your disc drive.

This Russian business site 404 page is liable to make you forget what you were looking for, even if you don't understand a word of Russian (or Romanian -thanks, !). Let's all dance! This animation is found at more than one Russian site, so it's probably a feature of the hosting service. Warning: the song might be in your head all day.

Blue Fountain Media would like to develop websites and apps for you, but if you reach their error page instead, they offer on online version of Pac-Man for you to play. That makes everything all better, doesn't it?

Titlest golf equipment knows when you've lost a link, and they'll pitch in to help you look for it. In the rough. They've found a lot of golf balls there, after all.

Joel Veitch composed a song and video for Rathergood's 404 page. As you might guess, it's sung by a kitten.

Oh dear, you've got a 404
This isn't what you came here for
Oh dear, you've got a 404, there's nothing here to see
Oh dear, you've got a 404
This isn't what you came here for
Now that you're here, let's have a 404 party!

It's just as silly as anything you could possibly be looking for in his archives.

Woodland Farmers Market sells fresh produce in Washington state. They are also Star Wars fans and punsters.

Mashable did not find the page you're looking for. But they found your socks, so that's a plus, huh? Hey wait, who's wearing my socks? Oh, that's okay, they've got a hole in them anyway.

Bluegg is a company that designs websites. They also designed a sweet 404 page that says,

Ahhhhhhhhhhh! This page doesn't exist
Not to worry. You can either head back to our homepage, or sit there and listen to a goat scream like a human.

I listened to that goat scream quite a few times while preparing this item.

The Rolling Stones website gives you a video on their error page. A very appropriate video.

To be honest, these error pages came from a list that I've been keeping for seven years now. I just added to the list as I found great 404 pages, but I hadn't stopped to check how long the list was until recently. Over the years, many great error pages were lost because the website went out of business. Others just don't seem that creative anymore. Some error pages were changed or gutted due to copyright violations. To save time, I had kept a few posts that were lists of great error pages. Now I find that those posts no longer exist, and the links redirect to boring, everyday error pages. If you know of a wonderful error page everyone should see, please tell us about it!

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!

Scientists Think They Know How Whales Got So Big
May 24, 2017

It can be difficult to understand how enormous the blue whale—the largest animal to ever exist—really is. The mammal can measure up to 105 feet long, have a tongue that can weigh as much as an elephant, and have a massive, golf cart–sized heart powering a 200-ton frame. But while the blue whale might currently be the Andre the Giant of the sea, it wasn’t always so imposing.

For the majority of the 30 million years that baleen whales (the blue whale is one) have occupied the Earth, the mammals usually topped off at roughly 30 feet in length. It wasn’t until about 3 million years ago that the clade of whales experienced an evolutionary growth spurt, tripling in size. And scientists haven’t had any concrete idea why, Wired reports.

A study published in the journal Proceedings of the Royal Society B might help change that. Researchers examined fossil records and studied phylogenetic models (evolutionary relationships) among baleen whales, and found some evidence that climate change may have been the catalyst for turning the large animals into behemoths.

As the ice ages wore on and oceans were receiving nutrient-rich runoff, the whales encountered an increasing number of krill—the small, shrimp-like creatures that provided a food source—resulting from upwelling waters. The more they ate, the more they grew, and their bodies adapted over time. Their mouths grew larger and their fat stores increased, helping them to fuel longer migrations to additional food-enriched areas. Today blue whales eat up to four tons of krill every day.

If climate change set the ancestors of the blue whale on the path to its enormous size today, the study invites the question of what it might do to them in the future. Changes in ocean currents or temperature could alter the amount of available nutrients to whales, cutting off their food supply. With demand for whale oil in the 1900s having already dented their numbers, scientists are hoping that further shifts in their oceanic ecosystem won’t relegate them to history.
