So far today I have been wrestling with getting my dissertation experiment bundled into a standalone app via py2app. Including opencv seems to be troublesome. Until I find a solution to the opencv problem, I’m going to comment it out and focus on speeding up the real-time response force feedback on the display machine.

Wednesday, November 9th, 2011Spent most of the day working on coding my first dissertation experiment, which will use an xbox gamepad’s analog triggers to index response force. I came up with a cool way to provide visual feedback of response force as well as response type, but I need to do some optimization of the code to help it avoid dropping frames. Engaged Jon Mulle to work on translating this opencv C++ code to python for use in my experiment for eye monitoring via webcam.
Talked at length with Matt Hilchey regarding the state of science and our shared disillusion with the scientific publishing process. Advised Heath Matheson on mixed effects analysis of multinomial data. Posted an answer on stats.stackexchange.com regarding analysis of questionnaire data.
Trying again…
Wednesday, November 9th, 2011After multiple discussions with colleagues, I’ve decided to give the whole open lab notebook thing another try. I’m about to start up data collection for my dissertation as well as a comp project, so this is probably an optimal time to start up again. I’ll try to update the page every couple hours with what I’ve done since the last update.
Mental Chromometry updated again
Sunday, December 27th, 2009I just posted a pretty substantial update to my work on mental chromometry. Posted a new manuscript including a corrected model and enhanced estimation algorithm.
Open musing
Sunday, November 29th, 2009It’s been a while since my last content posting. Part of my failure may be due to the usual seasonal influences, but I think I’m also finding it difficult to justify placing work here at a higher priority than the low position at which it has apparently fallen. I guess this is one of the difficulties in motivating scientists to engage in open notebooks; the benefits of such an enterprise are long-term and abstract compared to the day-to-day necessities of doing science. Yet I remain committed to the idea that the trade-off ultimately sides in favour of the investment in an open notebook, and I will endeavour to find ways to remind myself of this when my own motivation wanes. (I’ve obviously been exposed to the literature demonstrating that public resolutions are the most effective means to behavioural modification)
Another aspect of open notebooks that has troubled me of late is the prospect of getting scooped. When initiating this exploration, I knew that this was the primary concern of most scientists when the idea of an open notebook is proposed, and I allayed my own fears by convincing myself that: (1) open notebooks themselves provide proof of priority of a sort; (2) anyone seeking to mine my postings for scoopable material would likely remain a step behind me, since they’d only get access to my work only up to my latest posting; and (3) being scooped may be an acceptable cost-of-business if the benefits of open notebooks become more prevalent. Of course, (1) is only really relevant for future historians of science, since within the annals of science itself peer-reviewed publication is (and should?) be the standard for priority. (2) is also somewhat dubious in that it necessitates intentionally delayed posting of material, which somewhat violates the spirit of openness. So lately I am left with (3), which again necessitates elevating an long-term/abstract gain against immediate concerns of cost.
On the other hand, I recently experienced a great example of the efficiency of openness while attending the 50th annual meeting of the Psychonomics Society last week in Boston. The poster sessions were a great opportunity to interact with other scientists and share ideas about each other’s work. I’ve hopefully drummed up a couple collaborations out of the experience. I did, however, feel a pang of regret immediately after pointing out a flaw in one poster and suggesting to the author an easy solution. I think it was the fact that the solution was easy, so easy I could have done it myself, that made the interaction feel like a missed opportunity. On the other hand, while it would have been easy for me to implement the solution, it would certainly have been even easier for the poster’s author to implement it, since he obviously had most of the experiment already coded. Hopefully by fostering an atmosphere where scientists value the long-term efficiency of openness over immediate potential gains through closed competition, we’ll speed the progress of science.
In a similarly vein, hopefully down the road I don’t look back on sentiments like this as exemplifying the naïveté of youth!
ggplot2 book is available via Amazon
Wednesday, August 19th, 2009Hadley Wickham, author of many of my favorite R tools (ggplot2, plyr, reshape, crantastic), has a ggplot2 book now on sale at Amazon. I wrote a short review.
