Techie Litmus Test

The audience is now divided into two groups: the techno-Muggles are staring at the comic, wondering WTF it’s supposed to mean. The rest of us are laughing hysterically, perhaps literally ROFL*, at the thought of counting sheep using signed integers. Who but Randall Munroe would have thought of a cartoon gag about twos’ complement math?

This is a great example of why XKCD is so cool. Only once in a great while will a comic come along that truly Gets It and shows us another aspect of Truth. Calvin and Hobbes, Non Sequitur, and The Far Side come to mind. This is great stuff. But don’t just take my word for ittake a look at some for yourself!

…and then there’s the Map of the Internet. (Yes, really. It’s a classic.) And also Geohashing — a new meme…

* Note to self: Don’t read XKCD at work anymore, even on break. The Muggles will hear you laughing for sure!

Coolest. App. EVER.

I’ve just discovered Crayon Physics. Remember playing with crayons as a kid and imagining your drawings coming to life?

Well, imagine no longer. This is an excellent example of why computers are so cool. I’ve known about this for maybe a day or so, and already I’m thinking of it in terms of some of the Great Games I’ve known: Zork, Flight Simulator, Oblivion, etc.

Don’t bother with the instructions; just let your inner kindergartener out to play with it and you’ll figure it out in no time.

Take a look — it’s really amazing.

EDIT: (No, this is not an April Fool’s joke.)

In Soviet Russia…

…memes perpetuate you!

OK — how I wound up having the “first” comment on the first video on YouTube, I’ll probably never know. Especially since I know for a fact that I wasn’t the first to comment (click the button to show the replies marked as spam if you don’t believe me). But judging from the number of “d00d u haz teh f1rst YouT00b commend eVar!” replies I get, I’m in danger of becoming a meme.

Apparently the word was coined by Richard Dawkins, though — so it’s not all bad.

im in ur youtubes confusing ur memes

Stupid Robot Tricks

New video — getting two robots to “share” access to an object. (Robot B waits for the signal from Robot A before starting, then Robot A waits its turn for the cycle to start over.) Since the robots aren’t bolted down, the positions drift — the solution for this is to either secure them or run them at a slower speed. The test works as a proof of concept and test of the communications between the two, though.
