Some tools I like/use/tolerate
Human observer experiments || Statistics || Writing right || Backups || Productivity || Useful websites || Social media resources
No psychophysicist's toolbox would be complete without the open source application PsychoPy.
It's actually a great tool for preparing, executing, and managing most types of subjective experiments with almost any kind of visual stimuli.
For statistical analysis and generating fancy plots, I've come to (more or less) love R. If you really want to spend the rest of your life in the 5th circle of Inferno, don't backup any of your data (e.g. code, research, pictures of your cats). Hardware failures do happen, and they happen often. I make sure to have at least two copies on different media.
I don't actively participate on Twitter, but here are a few interesting accounts I follow:

Human observer experiments
For multi-reader multi-case ROC studies, I've used the Dorfman, Berbaum, & Metz (DBM) software
and power estimation script in several experiments.
Lies, damned lies, and statistics
I use Rstudio as a graphical user interface for R.
R-bloggers is great site/blog for R tips and inspiration.
Also follow #rstats and these fine R handles on Twitter!
