To some, The Kentucky Derby is a time-honored American sporting event that has been around for 140 years. For others, it’s the premier place to check out some of the world’s most elaborate hats. And when it comes to Derby headgear, “bigger is better” is definitely the mantra. While seated (read: fancier) attendees tend to opt for the kind of elegant head-topper you’d see at a Royal Wedding, there are no rules when it comes to the general admission crowd.
Still, the event’s organizers are kind enough to offer some general guidelines for how to dress for the annual event, stating that “Wearing a hat to the Kentucky Derby is believed to bear good luck! The long-established fashion was started by the women, however, over the last few years, many men have taken part in the tradition as well. Wearing a hat is much like getting into costume, you might be pleasantly surprised to see what type of character you become. From the fantastic to the sublime, there are no rules or limits.”
On his YouTube channel Mind Your Decisions, Presh Talwalkar shares logic puzzles dealing with geometry, statistics, and algebra. The puzzle below from the former Stanford math and economics student features no numbers, but that doesn’t mean it's easy to figure out.
To solve the brain teaser, you need to guess the secret word based on a few clues. Here’s the set-up: A teacher is leading a class and Albert, Bernard, and Cheryl are his students. He writes the words "cat," "dog," "has," "max," "dim," and "tag" on the board. He distributes one sheet of paper to each of his three students, with each piece containing a different letter from one of the words. He then tells them that together their letters spell one of the words on the board. The students only know their letter, they don’t know anyone else's.
The teacher asks Albert if he knows the secret word. Albert says yes, he does know it. Next, the teacher asks Bernard. After some hesitation, he replies that yes, he knows the secret word as well. Finally, the teacher asks Cheryl if she knows what the word is. She thinks for a moment and says that yes she does. Albert, Bernard, and Cheryl have successfully guessed the secret word. Do you know what it is based on their answers?
Figuring out the word without knowing any of its letters may seem difficult, but it’s not impossible. If you don’t know where to start, think about Albert’s answer and use the process of elimination to rule out some of the letters and words written on the board. Keep in mind that Bernard could only come to his conclusion from Albert’s answer, and Cheryl from Bernard’s.
Still lost? If you haven’t gotten to the bottom of it yet, the correct answer is "dog." When Albert answers that he knows what the right word is based on one letter, you can use that information to narrow down his possible letters to one of the six that are never repeated on the board: c, o, h, s, x, and i. And when Bernard says that he knows too, you can deduce that his list of potential letters is limited to t, g, h, or s. That leaves "cat," "dog," and "has" as the three remaining options. Cheryl’s answer confirms that she has the letter d, which means the secret word is "dog."

In the '90s, a significant amount of computing power was devoted to generating endless brick mazes on Windows 95. The screensaver has since become iconic, and now nostalgic Microsoft fans can relive it in a whole new way. As Motherboard reports, the animation has been re-imagined into a video game called Screensaver Subterfuge.
Instead of watching passively as your computer weaves through the maze, you’re leading the journey this time around. You play as a kid hacker who’s been charged with retrieving sensitive data hidden in the screensaver of Windows 95 before devious infomancers can get to it first. The gameplay is pretty simple: Use the arrow keys to navigate the halls and press Q and click the mouse to change their design. Finding a giant smiley face takes you to level two, and finding the briefcase icon ends the game. There are also lots of giant rats in this version of the screensaver.
Screensaver Subterfuge was designed by Cahoots Malone as part of the PROCJAM 2017 generative software showcase. You can download it for free for Windows, macOS, and Linux from his website, or if playing a game sounds like too much work, you can always watch videos of the old screensaver on a loop.
