Here is an xorg.conf for a Gentoo guest running in VMWare Fusion on MacOS 10.6 (Snow Leopard). It’s surprisingly simple to set up X when the hardware is fake 😉 Gentoo runs great on a Macbook Pro 13″. I was concerned at first about the lack of 3D acceleration, but I tried a few 3D […]

I recently installed Gentoo Linux (amd64) as a guest on my Mac (OS 10.6 Snow Leopard) using VMWare Fusion. I thought I’d post the kernel config that I am using, since I didn’t find any out there that I trusted. If you can use this as a starting point, then it should save you some

In a previous post, I explained how to use the Python profiler. The profile is great for finding out which parts of the code run the slowest, or are called most often. However, the profiler doesn’t give any information about how much RAM is being consumed, or where it’s being consumed. If your program needs

It’s a real pain to surf the Web when the batteries die in your wireless mouse or trackball. I use some old rechargeables that are no longer fit for digital camera service, so this happens to me fairly often. My batteries just died again, so I had to figure out how to configure X.org to

My simulation library, which is written mostly in Python, needs a lot of data and parameters in order to run. In some cases, I just hard-code the values in the script that calls the library, and in other cases I load a pickle file containing a Python objext. What if I want to read in

Writing applications in Python on a Linux system is almost too easy. Deploying Python apps on other Linux systems is not hard, because most Linux systems already have Python, with its core libraries and tools, installed. Most Linux systems also have package managers that make it easy to find and install required components. But, what

I recently found a solution to a problem that had been vexing me for about a year. In order to successfully import anything from scipy.integrate, I had edit the file scipy/integrate/__init__.py and comment out the line from odepack import * If not, I would get various import errors such as Traceback (most recent call last):

I have found a few tools over the years that I find extremely useful for developing software. Python is my language of choice at the moment, but I’m sure these tools will be handy for any language. Subversion is an open-source version-control system. Version control was designed to allow multiple programmers to work on the

NOTE: these instructions are obsolete. Please see Building NumPy on a 64-bit Red Hat Cluster with Intel MKL. In a previous post I described how I built Numpy with Intel compilers and the Math Kernel Library on a 64-bit cluster. Today I upgraded to Numpy-1.2.1 and I made a few improvements to my install process. Please

VTK is an open-source software system for “3D computer graphics, image processing, and visualization” developed by by Kitware. VTK is the foundation of Paraview, an industrial-strength CFD visualization tool that I have found to be very useful. I generate “second generation” XML-based files from my Python code and import them into Paraview for visualization. I
