future gcc/gfortran releases on Mac OS X — they may be going away
Fellow researchers using OS X, The GNU steering committee has decided to remove OS X (intel) from their primary target list, and OS X (power pc) from their secondary target list. This means that future releases of gcc may not work on OS X. I presume many of you compile…
Showcase: Vibration Turns Your iPhone into a Spectrum Analyzer
Vibration is a true vibration spectrum analyzer using the built in accelerometers inside the iPod Touch and iPhone. It acquires and displays time series data, optionally removes DC bias, applies a Hamming window and performs an FFT on each channel to produce frequency spectra. The accelerometer has a sensitivity of…
CUDA: A Quick Look and Comparison of FFT Performance on Mac
Like many scientists, we’re interested in using graphics cards to increase the performance of some of our numerical code. With the addition of CUDA to the supported list of technologies on Mac OS X, I’ve started looking more closely at architecture and tools for implemented numerical code on the GPU….
Open Source Support
What are your experiences porting legacy code to OS X. Would you like to use compilers other than those currently supported by XCode. Think about an Automator script that performs: Xcode Transition: Doing It RightBefore you migrate a project to Xcode, you can take a few steps that will save…

Data Analysis tools For Mac
Scott Hannahs has compiled a fabulous list of the tools for Data Analysis available for Mac OS X for the SciTech mailing list and I thought it would be useful to spread the word. Remember that many of the more expensive applications have free/cheap education or student versions. Free =…
