neatorama presents: HDYK? – {day 2}

It’s an all-new 5-day trivia hunt!

Co-puzzle Master Josh Halbur and I are happy to bring you the next How Did You Know? sponsored by our friends over at neatorama.com.


Here’s how it works: Every day the rest of this week, we’ll be presenting two challenges at noon ET. They’ll be very similar to the kinds of puzzles you’ve come to expect from me and Josh, and, yes, they will feed into the Day 5 puzzle, as normal. Each evening, at 8pm ET, we’ll be putting up a third challenge loosely based on the day’s previous two challenges. You won’t need to solve the first two to solve the third, but knowing the day’s theme might help you be the first to crack Level 3. Also: note that you’ll have to solve Level 3–the bonus–to compete on Day 5

>> Prizes! Each day, one person will win one item from the neatoshop worth $25 or less. Shipping is on the house but the item you pick must be in stock. Oh, and no credit if you don’t use up the full $25. To be eligible for the prize, you need to leave the correct answer to Level 3 on the correct neatorama page before 10pm ET. You also need to tell us in that comment what you want if you’re selected at random.

>> So what’s in it for the person/team who finishes first with all the correct answers? Bragging rights, as always, with your photo/bio posted on our site. But also the chance to win the Day 5 neatorama prize, and, as has been tradition here for the last 28 months of HDYK?, your pick of any one of the amazing t-shirts from our store.

As always, if you’re not a Fan of our Facebook page, be sure to add us so we can keep you updated, and you can get in on some additional nifty clues throughout the week. If you’re new to our five-day hunt, you can read up on our new Rules page here. Oh, and yesterday’s challenges can be found here if you missed it. Okay, ready to get your Hunt on? Click on through.

New AI-Driven Music System Analyzes Tracks for Perfect Playlists

Whether you're planning a bachelorette party or recovering from a breakup, a well-curated playlist makes all the difference. If you don't have time to pick the perfect songs manually, services that use the AI-driven system Sonic Style may be able to figure out exactly what you have in mind based on your request.

According to Fast Company, Sonic Style is the new music-categorizing service from the media and entertainment data provider Gracenote. There are plenty of music algorithms out there already, but Sonic Style works a little differently. Rather than listing the entire discography of a certain artist under a single genre, the AI analyzes individual tracks. It considers factors like the artist's typical genre and the era the song was recorded in, as well as qualities it can only learn through listening, like tempo and mood. Based on nearly 450 descriptors, it creates a super-accurate "style profile" of the track that makes it easier for listeners to find it when searching for the perfect song to fit an occasion.

Playlists that use data from Sonic Style feel like they were made by a person with a deep knowledge of music rather than a machine. That's thanks to the system's advanced neural network. It also recognizes artists that don't fit neatly into one genre, or that have evolved into a completely different music style over their careers. Any service—including music-streaming platforms and voice-activated assistants—that uses Gracenote's data will be able to take advantage of the new technology.

With AI at your disposal, all you have to do as the listener is decide on a style of music. Here are some ideas to get you started if you want a playlist for productivity.
