I use Dvorak exclusively and echo the other comment -- I'm not sure that it has made a dramatic difference in my speed, but it is much more comfortable! Your hands sit neatly on the home row, and do not have to reach much.
The only downside is that I use vim and after many years of Nethack am pretty good at hjkl movement, and I can't even take advantage! :( Definitely something to consider though if you want to switch and are a vim user.
I use org-mode in emacs for this! I usually keep notes on whatever task I am working on, and more general programming notes which I file into tagged headlines for easy reference later.
does that really recompense for the possibility of sustaining permanent damage to a product you purchased on a marketplace you believed to be safe? Is it really ok to sell fraudulent products that could harm the user as long as you give a full refund? fine, but the trust is destroyed. This seems like an effort to avert bad publicity, I don't think they would email a customer about a fraudulent product in any other case.
