RHS on Hungarian notation
I have to admit that I used it, and it was a throw back to when I had to use VBscript in ASP.old pages. I made the mistake of having code samples out there using it today and I still get blasted for it, and justifiably so. Early last year I finally let it go because I was lazy, and because the contract I was on (auto insurance giant Progressive) adhered strictly to the standards set in various Microsoft docs.
