Commute Times - From the world of Awesome Visualizations

-
Trulia has really managed to hit one out of the park here - they've put together heat maps for commute times for various cities around the country.  You can (kinda) thank Google for this - Trulia used the GTFS spec that they popularized as well as OpenStreetMap to put together this awesome chunk of awesomeness. 
Basically, put in your city, and get a heat map that shows you commute times (driving as well as mass transit) within 15 minutes, 27 minutes, or heck, whatever you move the slider around to.

Oh, all the other Trulia goodies are there too, viz., School ratings, Crimes, etc.
Go check it out!

The fruits look like Cannonballs (well, d-uh), and the flowers are really quite amazing, and pretty ludicrously distinctive...

Erlang, Binaries, and Garbage Collection (Sigh)

The nice thing about garbage-collection is that it is makes memory management absolutely transparent to you Of course, the above is true right up to the point when it stops being transparent, at which point it does a phase change from nice to clusterf**k of biblical proportions .  There are entire posts, books, and suicide notes that have been written about this, and I have no great desire to add to them, save with the minor comment that paranoia about garbage-collection is still justified , albeit only in the edge-cases for most people. That said, I'll give you that Erlang GC is in many ways much, much better positioned in this regard than, oh, Java, but it still rears up and bites you in the butt when you least expect it. ( More information about Erlang's GC vis-a-vis Java here , and Jesper's truly excellent description of Erlang's GC here ).  A story from the past should serve to illustrate this. Once upon a time, in a magical land far far away - well, Her

Visualizing Prime Numbers

-
Image
From Jason Davies , we have El Patron de Los Primos , probably one of the coolest prime number visualizer that I've seen.  For every Natural number, he draws a periodic curve that intersects at that number and each of its multiples.  Needless to say, prime numbers are touched by only two curves (itself and 1 ). You can scroll to the right, and move up the prime food change. (The image above is a screen grab.  Go here to see the actual thing)
