Because it’s Friday: Stochastic degradation

June 4, 2010
By

When you upload a video to YouTube, they don't store a perfect digital copy of your media file. The video is actually re-encoded into the MPEG-4 video format. This saves space on YouTube's servers, but also introduces some random degradation to the video (as a result of the lossy compression process). So what happens if you then save that...

Because it’s Friday: The dating equation

According to internet lore, there's a mathematical equation that governs the lower bound for the socially acceptable age of a potential dating partner: half your age plus 7, or, in mathematical terms, if x is your age then the lower bound is f(x) = x/2 + 7. Seems simple, right? if you're 20, then the minimum socially acceptable age...

Because it’s Friday: Ash

I lived for 10 years within sight (on a clear day, anyway) of Mount St. Helens, and had seen and heard a lot about the devastation caused by the eruption and pyroclastic flow 30 years ago. But I'd heard relatively little about the effects of the ash cloud settling on land. I was surprised to learn about the effect...

Calling all T-shirt designers

Got design skills as well as R skills? The organizers of the useR! 2010 conference are looking for a design to be used on the conference T-shirts. Mango Solutions (who are sponsoring the T-shirt) will select the winner, but personally I'd give extra points for designs that use R itself -- it's been done before! R-statistics blog: useR-2010 is...

Which font uses the most ink?

If you're being particularly cost-conscious about your use of printer ink or toner, you may be wondering which font you should choose to minimize ink use. Here's an infographic with the answer: This is an interesting infographic in its own right, but what makes it cool is that these are not photoshopped images of Bic biros. Matt Robinson created...

Because it’s Friday: Four chords, and the truth

April 23, 2010
By

This one's for the musicians out there. (By the way, in my purely anecdotal experience, musical aptitude appears to have a higher-then-expected representation amongst stats folks. I however am the exception that proves the rule, as anyone who's suffered through my Rock Band vocals can attest. But I digress.) What do the chords C#minor, A, E and B have...

Because it’s Friday: Pixels invade New York

April 9, 2010

Posted for no other reason than it warms my gamer-geek heart to see NYC taken over by 8-bit video game characters. The Tetris sequence is particularly cool. Update: The original video was deleted from YouTube, I'm guessing because of copyright issues with the music. This version has no music. (Thanks to reader MB in the comments for the heads-up.)

Because it’s Friday: Chatroulette

Yesterday, Drew Conway posted an analysis of the survival time to events on Chatroulette. If you're familiar with Chatroulette, you'll know what kind of events you can expect to occur when using it. (If you're not, here's a hint: don't try it now if you're at work.) Sadly, it was all an April Fool's Day joke. But Drew takes...
