'Diverging Diamond' Traffic Flow

http://www.npr.org/templates/story/story.php?storyId=120403340

It's not often that you can make traffic flow more smoothly and safely without spending significant time and money. But drivers in Springfield, Mo., are the first in the United States to use a new interchange design that transportation officials say is quick, cheap, and safe.

The "diverging diamond" is being put to the test. Fans of the new highway interchange design say it improves traffic flow by eliminating problematic left turns. There's just one catch: It briefly sends all cars over to the left side of the road.

Follow the link for a diagram.

Plaxo plugin disabled by 10.6.4 update

Just FYI: After updating to Mac OS X 10.6.4, Apple Mail complains about an incompatible plugin.

> Mail has disabled the following plug-ins:
>> PlaxoMailCTC
>> Contact the makers of these plug-ins for versions that are compatible with Mail 4.3 and Message 4.3.

I reported the problem to Plaxo.com. As long as the rest of plaxo works, I'm not too worried, but I'll need to do some more testing before I'm sure it's OK.

By the way, Plaxo is a free tool that synchronizes your contacts and calendars among several computers. It mostly works fine.

Carte - clojure relational mapping

http://github.com/brentonashworth/carte

Carte is relational mapping for Clojure. It maps nested immutable data structures to an underlying relational database management system. It is meant only to provide simple access and manipulation of relational data, it is not meant to be a replacement for SQL

 or relational algebra.

Tom Watson at the US Open

Tom Watson is my favorite Stanford golfer.  He'll be playing in the US Open at Pebble Beach starting on Thursday.  Good luck, Tom!

In Watson’s 1982 U.S. Open win at Pebble Beach, he holed a touchy chip shot from the greenside rough to birdie the 71st hole—arguably one of the greatest pressure shots ever—and then birdied the 18th to top Nicklaus.

JavaScript Blacklist - extension for Safari

(via daringfireball.net)

I used to edit /etc/hosts to block these bad guys.  Now, there's a Safari extension for non-programmers to use.

http://homepage.mac.com/drewthaler/jsblacklist/

JavaScript Blacklist is a simple extension for Safari 5 which blacklists scripts from a configurable list of domains. If a common "utility" script used by sites that you visit is annoying you, this will let you opt out quickly and easily.

Here are some examples of common annoying scripts. JavaScript Blacklist comes pre-configured to block these by default.

• tynt.com - modifies copy-pasted text
• intellitxt.com - green links with double-underlines
• snap.com - link previews

Accessing the App Engine Datastore - Compojure on GAE

http://compojureongae.posterous.com/accessing-the-app-engine-datastore

To use the datastore API I need to include a jar that comes with the GAE SDK in my app. I could call the Java API directly, but there are already a few Clojure libraries that provide friendly wrappers around it. One of the first (that I know of) was appengine-clj by John Hume (who was also one of the first to write about using Clojure on GAE).

I decided to go with this fork of appengine-clj by Roman Scherer, which seems to be more complete and actively maintained.
