A careful look at some EXIF data displayed by PixelPost indicated some inexplicable discrepancy. Also, having to manually enter all the Lens information for each image was becoming tedious. Using Phil Harvey's EXIFTool utility, I hacked PixelPost code to come up with a new tag - <CUSTOM_EXIF> The work-flow is as follows:

• Run exiftool on RAW Image and extract the necessary information into a file.
• PixelPost will read this file on the fly and display the information contained within.

Modified work flow is as follows:

• Run exiftool on RAW Image and extract the necessary information into a table in PixelPost database.
• Manually update another table with additional useful information (lighting, GPS coordinates, tripod/flash/filters usage, special techniques, etc.) in PixelPost database.
• PixelPost will pull out the records corresponding to a given image from these tables.

Developing a set of scripts that would automate customization of new(er) linux boxes. The Super-Script, to be run as root, is called MiME - Moving in Made Easier. Idea is to remove repeatitiveness and hence remove any/all mistakes while customizing, installing, compiling a bunch of software/utilities on a bunch of machines.

Effectively employed when our research group got four brand new work-stations to replace the old ones (ganesh, vishnu, shiva and laxmi) in July of 2007.

Setting up a Beowulf Linux Cluster using (old) desktop computers. Mostly to play around, learn a few tricks, do some benchmarking and practice MPI.
