  • Pictorial Guide to Interpreting Infrared Spectra

    Having taught spectroscopy for several years, I find that students commonly have a hard time prioritizing IR bands in their spectra interpretation.  After several false starts and long years of procrastination, here’s a pictorial guide that I hope would be clear, accurate, and helpful for learning to interpret IR spectra.  If you wish to use…

  • ChemDoodles, ISISDraw, BKChem, MarvinBeans, ChemSketch, ChemDraw…

    There’s at least a dozen chemical structure editors running under different kinds of licenses and platform, and (ugh) none of them are truly satisfactory.  The latest one I’ve checked out is ChemDoodle, which is somewhat new and have some good things going on.  The existing reviews on the Net dates to 2004/5, so a fresh…

  • Web Adventures: evaluating what to learn

    The past few weeks I’ve been greatly distracted while writing. Trying to build a supporting app for my dissertation and the inertia kick from chemdoodle web components brought me to learning Java / JavaScript. I’ve known for sometime that I need to learn web-dev for OpenChemArt (amongst other things), but haven’t put serious thoughts into…

  • How NOT to swim distance butterfly?

    Since promising Cindy to teach her how to swim a long and efficient butterfly, I’ve been watching swimmers of various fluency at my pool (not very hard – swimming fly attracts butterfly like daffodils 🙂 ) as well as videos of exceptional swimmers like Misty Hyman and Mike Phelps online.  I’ve since learnt that it’s…

  • Anonymous vs the “Patriots”

    Visualizing the damage done in the so-called “first world information war“* up to Dec 10, with each unit representing one hour of downtime.  The data was extracted from PandaLabs’ blog.  Downtime on the top is largely from Anon‘s** Operation: Payback (and is investigated by US-DOJ and an arrest in the Netherlands); downtime to Wikileaks was…
