# Summary of IRC Log from July 28, 2012

* A discussion about DIY spectrometers revealed that DVD media can be used as a diffraction grating (a "poor man's prism") in homemade spectrometer designs, with a link shared to a related Flickr photo.

* Open Source Ecology (OSE) was discussed, particularly their recruitment for a steam power project manager position paying only $2,000/month with restrictive conditions including a required unpaid orientation period.

* Participants debated CAD software challenges for open hardware projects, noting that OSE has plans for a "$1/2M fully-featured, open source CAD/CAM solution" but currently lacks proper CAD file sharing.

* A discussion about banana allergies and immunology emerged after the banana genome sequencing was mentioned, with participants noting that autoimmunity is complex and multi-factorial, making it difficult to isolate specific allergens.

* A Python-based Tesseract OCR trainer tool was shared (https://github.com/BaltoRouberol/TesseractTrainer), with the suggestion that proper training might improve OCR results.

* There was a brief discussion about wiki platform preferences, with some frustration expressed about fragmentation across different wiki platforms rather than consolidating information.
