I came across the following video ("The JavaScript Programming Language") that is a lecture by Douglas Crockford (who is a "JavaScript Architect" at Yahoo!) in which he discusses JavaScript. It is split into four 30-minute parts (totaling 2 hours):
It's useful to download the slides because the video doesn't always show them when he is referring to them.
It is a good introduction to JavaScript, explaining how parts of the language works as well as offering advice on how to use (or not use) various features of it. He also talks some about the history of the language.
Here are some good articles on how to get going with Postgresql on Ubuntu:
http://help.ubuntu.com/community/PostgreSQL
And Mac OS X 10.5 (Leopard):
http://www.z1r0.com/2008/03/configuring_postgresql_82_in_o.html
Note that version numbers don't matter, as I was able to apply these instructions to Postgres 8.3.
I also find the pgadmin3 tool to be very helpful with Postgres. In Ubuntu you can find it in the repositories, in Mac OS X, you can get a binary to install from here.
In this entry I discuss reasons to switch from Axis to XFire, and then how to get XFire as a server working nicely with .Net as a client.
I have written some past entries about Java/.Net web service interop, specifically how to get a Java Axis server working with a .Net 1.1 client. Now with .Net 2.0 we have nullable types built in to the language which removes the need to use the 3rd party library NullableTypes to handle nullable values.
I had Rails installed using Debian packages from the official repository and thought I'd try out RoR development. So I started the cookbook example in the article Rolling with Ruby on Rails. Not so fast, I was getting an error because it was not properly translating the domain object name to the correct database table. It was not translating "Recipe" into the "cookbook.recipes" table like it should, and instead was looking for the table "cookbook.Recipe". I worked around this by changing the database table, but that only worked until I tried to add more than one record.
