During the day, I create software to forecast retail sales and calculate order proposals. Lots of time series, with an emphasis on fast, automatic and robust data cleansing and forecasting. I'm an elected director for the International Institute of Forecasters and an Associate Editor for their practitioner-oriented forecasting journal Foresight. At night, I switch hats and do inferential statistics for academic clinical and biological psychology. My main tool is the statistical computing environment R.

See xkcd on the impossibility of double-blind study protocols.

comment Is there evidence that GTD increases productivity?
@Superbest: sure, people are trying. But many easy approaches don't work or send perverse incentives (what's a programmer going to do if you measure his productivity by lines of code, or number of classes, or number of bugs fixed?). Other approaches, like 360 degree reviews, work better, but they are expensive to implement and still subject to noise & politics.

comment Is there evidence that GTD increases productivity?
+1. It's already hard enough to quantify "productivity" as such (lots of people are thinking hard about this in the context of bonus payment schemes). It'll be even harder to compare different interventions to improve productivity, given issues like selection bias, compliance, the impossibility of blinding participants (of course, raters could be blinded) and so forth.

comment How to switch to a new, spam-free, email address but avoid checking the old?
Probably not. If there were such a surefire rule, you could just use it as your spam filter and keep this address.

comment How to love programming or my job
Hi, and welcome to Personal Productivity! I'd guess a few more details would help us answer your question. First, why do you want to love coding? Second, what specifically do you hate about it? You write that "I feel like I'm too stupid to learn." This looks like a good point to expand on. Could you give a few details about a situation where you needed to learn something, and how you failed at it?

comment Reducing mess - ideas from the Personal Productivity world?
@Olav: by getting me to use one (or more) Inboxes, which I go through in my Weekly Review, and by making me touch everything no more than twice. This has done wonders to clean up my desk. It will admittedly do less for toys lying around, so you'll need to do something different there, like getting into the habit of putting things away immediately, or scheduling 15-minute bursts of putting stuff away every day.

comment How to balance sleep in biweekly schedule
In your question, you write that school starts at 07:30pm, in your comment, you write 07:30am. I am confused and will vote to close. Please consider editing your question.

comment How to balance sleep in biweekly schedule
It is a bit unclear why your school schedule means that you can't develop a sleeping routine. I have a hard time imagining a school schedule that would make a consistent sleep routine, say from midnight to 8am impossible. Perhaps you could edit your question to clarify.
