Creating iTunes Scrollers

Apple introduced new scrollers in iTunes 7 and then moved on to give us the HUD, which many developers want their own scrollers for too. In Leopard, many of us thought that these would come in a nice, shiny box; but as they didn’t we’re all forced to roll our own. The common method is to draw all the components in Photoshop and then make a composite image when subclassing, but now with NSGradient and some nice additions to NSBezierPath all these have become quite easy to do, even for those with little artistic ability.

How-to: Install MCNP4C2 on Mac OS X 10.4.10 (Intel)

MCNP (Monte Carlo N-Particle) is a transport code that is used throughout the physics community to model how particles interact as they travel through a system. The code is quite old, and therefore requires tweaking to get it running on newer systems like Mac OS X 10.4.10. There are programs and compilers it needs to use when installing that aren’t included in Mac OS X anymore due to their age, and a few that are on the Mac OS X CD that came with your computer, but aren’t installed by default. The first things we need are:

A FORTRAN-77 compiler and a ‘C’ compiler of the same version.
The ‘fsplit’ program.
X11 installed.
The XCode tools.
