Installing BioPerl on Mac OS 10.6 Snow Leopard in 6 Easy Steps

The strategy I used to install BioPerl was as follows:

1. Use MacPorts to install Perl.
2. Use CPAN to install BioPerl.

Here are the nitty gritty details. You need a live internet connection, as both MacPorts and CPAN expect to be able to download packages.

Step One: XCode Tools

Before MacPorts can be installed, XCode Tools needs to be installed. This is free from Apple and can be installed from the original OS X 10.6 DVD or downloaded from Apple's developer site.

Solution to 100% CPU Usage by Linux Guest on VMWare Fusion

As part of my testing setup, I have an Intel Mac Pro with Mac OS X 10.6 Server (which runs with the 64-bit kernel) on which I run VMWare Fusion 3.0.1 and several Red Hat virtual machines.

I noticed that even at idle, each VM was taking up a high amount (like 100%!) of a CPU core. Additionally, on one VM top was displaying in near-real-time, which was kind of neat but I doubt the intended behavior. Because of this, I suspected the time management in the kernel was off.

APC UPS and Snow Leopard Server Not Communicating

I have used APC (American Power Conversion) power equipment for a long time. I have had both good and bad experiences with their products (a cherished memory is calling their technical support and asking about the "smell of burning plastic" emanating from one of their units).

I've recently upgraded an Intel Mac Pro to Snow Leopard Server (OS X Server 10.6.2) and noticed that the controls in Energy Saver for the UPS are different. Not in a good way.

Here's the relevant screen from OS X Server 10.5.8:

Eudora, Snow Leopard and Kerberos

I upgraded to OS X 10.6 "Snow Leopard" yesterday. A smooth upgrade except for one thing.

Eudora 6.2.4 for Mac OS X works on 10.6 (provided the optional Rosetta PowerPC-emulation code is installed), but not with kerberos.

To use kerberized POP, Eudora depends on the Code Fragment Manager library "Kerberos" which is part of the MIT Kerberos Extras for OS X package.

The actual library is installed to /System/Library/CFMSupport/Kerberos and is a 983k file last updated in 2003. It's labeled version 4.2.
