Xcode: How to Change the Company Name

No need to use the command line to do this.
It's a lot easier than I"ve seen done in several books.
Just change the Company field on your Address Book Card

Masterminds of programming

great quote from the book:
from one of the creators of Objective-C (Brad Cox):

Why is computer science not a real science?

Brad: Each time you encounter a new piece of software, you encounter something completely new and unique. How can you have a science where everything is unique?

If you study gold or lead from day to day, you can measure the properties and employ scientific methods to study them. With software, there is none of that.

Programmer Competency Matrix

Stuff that you should know as a programmer but will most likely never get around to LOL.
Oh well at least it gives a good high level view of how much stuff you don't know:
Note that the knowledge for each level is cumulative; being at level n implies that you also know everything from the levels lower than n.

Gotcha when installing VS2008 and SQL 2008

Visual Studio 2008 fails to install SQL Server 2005 Express if SQL Server 2008 Express or later is installed with the following error: "Component Microsoft SQL Server 2005 Express Edition returned an unexpected value"

Algorithms in C#: shortest path around a polygon (polyline routing)

Suppose you have to build a road to connect two cities on different sides of a lake. How would you plan the road to make it as short as possible?

To simplify the problem statement, a lake is sufficiently well modeled by a polygon, and the cities are just two points. The polygon does not have self-intersections and the endpoints are both outside the polygon. If you have Silverlight installed, you can use drag and drop on the points below to experiment:

new version of Visual Studio 2010 coming out soon

But like WTF it's only designed to run for a week before you gotta reboot your machine?
I guess that's Windows/Microsoft for you :(

The official sign-off criteria is that the end user needs to be able to keep VS open for an entire work week without any noticeable performance degradation (this means 5 days times 8 hours a day).

What CSC Graduates Should Know

Fundamental Algorithms
These are algorithms that students should know from memory (or with very little help from a reference).

1. Insertion sort.
2. Merge sort.
3. Quicksort.
4. Root finding (binary search, Newton's method).
5. Matrix multiplication (basic algorithm).
6. Gaussian elimination.
7. Radix conversion (e.g. binary to decimal and vice-versa).
8. Tree and graph traversals (preorder, postorder, depth-first, breadth-first)

Eclipse and Java for Total Beginners

Free video's for using Eclipse and Java.
Unfortunately they are in Flash format :(

Google AI Challenge

Welcome to the Google AI Challenge!

This year's Google AI Challenge is all about Tron. Tron is like two-player Snake, where your objective is to box in your opponent and make him crash into a wall or his own tail before you do! See the problem description for more information.

Check out the five minute quickstart guide to get started as quickly as possible!

The contest opens on February 4, and closes on February 26, 2010 at 11:59 PM.

Kasparov’s algorithm

Kasparov’s algorithm — “Weak human + machine + better process was superior to a strong computer alone and … superior to a strong human + machine + inferior process” — is that it suggests serious rewards accrue to those who figure out the best way to use thought-enhancing software.

Pretty cool!

Address Space Layout Randomization and VS problems

Error message when you use the Visual C++ 2008 compiler: "fatal error C1859"
When you enable the Create/Use Precompiled Header compiler option, the compiler requires that the precompiled header files and the relative modules do not move between compilations. However, the Address Space Layout Randomization (also known as ASLR) feature randomly relocates modules in a process. Therefore, the error occurs when modules move between compilations.
