This month has seen my Envy Code A and Envy Code B fonts stumbled upon some 4,000 times thanks to a Digg to Keith Deven’s programming fonts page that links here.

I’ve taken this opportunity to update the fonts – Envy Code B had a couple of issues with mis-positioned characters in the 9pt version especially with “il#” characters in the bold one. Fixed.

Anyone using object orientated programming soon finds themselves wanting to perform some action only if an object is of some type or implements some interface.

The easiest way is to do this is to use the isis operator. Typically it will appear something like:

Apple have announced the 17″ MacBook Pro at their US Store that should be shipping within the next 7-10 days (early May).

The machine is almost identical to the 2GHz models of the 15.4″ MacBook with the following differences;

One of the great new features in .NET 2.0 is support for nullable types – especially important when dealing with value types such as Int or DateTime values coming from a database. Previously you were forced to either set and track another binary flag or to use a “special” value to represent null that sooner or later would turn up in real data.

In C# 2.0 thanks to a bit of syntactic sugar we can do this;

Getting a new machine often spurs me to go out and find some new tools and utilities. Here’s some recent finds:

Kristian Dupont Knudsen has written a top 10 of programming advice notnot to follow with his rationalisation for each one. Being a programmer I thought I’d chip in with my 2 bits.

Joel recommends not using exceptions because they are “invisible in the source code” and that they create “too many possible exit points”.

This article was written when Boot Camp had limited device driver support and is now therefore out of date.

Apple’s Boot Camp provides the majority of drivers required including the elusive ATI Mobility Radeon X1600 driver however there are a few devices without official drivers. These are;
