I'm pretty sure "self diving cars" is a much better technology for ending drunken driving. Although, I did see an interesting argument about the presence of ethanol in gasoline essentially putting a car's own BAC over the legal limit to dive itself. Then again, none of that alcohol should be found in its "breath," thanks to the catalytic converter...
A new system called the Driver Alcohol Detection System for Safety, if implemented, could prevent a cause of death for almost 10.000 Americans every year. The technology for preventing drunken driving works off of on sensors that analyse alcohol levels in the car’s air. If a scan detects too high levels, the car will not …

Back in. Plus who wants to drink in Kansas anyway?

How to view someones IP address and connection speed!: https://youtu.be/SXmv8quf_xM

How is it that I only learned about this video's existence today?? This gem has been around since 2008! I've learned so much today, including the fact that I've been saying it wrong: "tracer tee!" This video is amazing.

Think there's little benefit to watching campy 1980's comedies? Wrong. There is a lot of vocabulary to be learned. The generation that has missed out on watching The Three Amigos probably also never learned words like "infamous" and "plethora." Only recent media tidbits like Geico radio commercials have really scratched the surface for "nada." (And really, even Geico missed the mark. Nada is obviously a light chicken gravy...)

An example. This article on Phandroid used "infamous," and a couple comments indicated that they did not know what that word means. They would have been much better off with the 23 peso version.
We didn't get many meaningful updates on Project Ara from Google IO, unfortunately. What we did get was a majestic moment of pride from one of the project leads holding the a working Project Ara prototype up like the infamous scene straight out of Lion King.

Give this generation time. You cannot force open the petals of a flower!

People of the media: "pi" is a mathematical concept. As such, those pesky digits actually mean something. Dates actually mean something, too, but that's a completely different concept. Also, "pi" and "pie" share common letters and pronunciation, but have little else in common (other than the fact that many pies are, in one dimension, circular). So "Pi Day" already combines three unrelated things, and is really just a fun thing to do. I support this. It's a great opportunity to focus the public's attention on a math! But, let's take the opportunity to represent the math correctly. Get the word out that the real high-precision Pi Day is next year: 3/14/16.

It is really irritating me that we are so casually saying that this year is a super special one for Pi Day. Why? Because tomorrow is "3/14/15," and pi, to 6 significant digits, is 3.14159. I threw that '9' in there because pi, to 5 significant digits is 3.1416. We have this concept of "rounding" for a good reason. Especially with irrational numbers, there is no way to precisely capture the actual number with digits. With every additional digit, the representation is a bit closer to the actual number, but it never gets there completely. (This is one reason we represent the ratio of a perfect circle's circumference to its diameter with a name -- "pi" -- rather than a digital representation.) Although you can never use digits to perfectly capture pi, you can capture something close, with measurable accuracy. For example, I could say that pi, to 5 significant digits, is 3.4567. That would be much less accurate than using the number 3.1415. It would be more accurate to say that it is 3.1416. This is true for the same reason that the number 59 is closer to the number 60 than it is to 50, or that someone who is 5'11" tall is more likely to say that they are "6 feet tall" rather than "5 feet tall."

So, sure, "Pi Day" is a fun gimmick, but it's one that draws public attention to mathematics in a way that few other other fun things do. Why use the event to spread mathematical ignorance? I'm looking at you, +HuffPost Live... 
Pi Day, Pi Day, gotta get down on Pi Day. Saturday marks "Pi Day," the one day each year the calendar's digits match up with "pi" or "π," the irrational number that expresses the ratio of a circle’s circumfe...

Couple of thoughts... I'm all for media bashing especially Huff Post but let's not restrict pi day. How about we expand the maths a bit. We can say yesterday was a super pi day (to 5 sig figs) using the floor func and next year will be a super pi day using the ceil func. Pretty sure some media pundits eyes will glaze over right before their brains explode. Extra fun.
