Neural Network Stock Analysis
I am applying that computational neuroscience math to stocks. I was in the process of running a Fourier decomposition on Starbuck’s data for the past three years (in R) when I realized that my sampling frequency was lower than 1.157*10^-5 Hz (longer than 1 day). While this resolution gives me a good look at the low-pass trends, I am interested in day-trading. So, I decided to find...

Does HTML5 Really Beat Flash? No.
the decision to block Flash is less of a technological one and more of a business-minded one. After all, if you could easily visit Hulu.com to stream TV shows and movies, then why would you need to buy them from the iTunes Store?

Steve Job's Rhetoric on the Flash iPhone / iPad...
Steve Jobs just wrote an essay on why Flash is “unfit” for the iPhone/iPad architecture, illuminating a new type of format war between Apple and Adobe. In his essay, Jobs employs numerous rhetorical strategies that may mislead those outside the developer stratosphere. While I am an avid mac user, I am also a long-time flash developer. Here is my critical analysis of Job’s...
LaTeX and OSX
Because there is no simple tutorial for getting the apa package in LaTeX to work (all of the information is loosely spread out across the internet), I decided to make a tutorial for the absolute beginner having some familiarity with the OSX terminal.
What is LaTeX and why is it useful for my research?
LaTeX is a type of markup (like HTML) that will turn your text into a beautifully typeset...

The Best Way to Gain Exposure to Research
I just sent this to all the psych majors at SDSU. Its good advice and its how I got here.
Dear Psychology Peers, I was impressed by the (overwhelming) number of responses for my neuroscience seminar/tour at UCSD. However, I noticed that many of you are sophomores and juniors who are just starting out and want to gain exposure to the field. This sort of experience is extremely helpful in making...

Wireless EEG Part 2
So, after my last (lengthy) post on why the older NeuroSky headset is no good, I contacted the VP of R&D and explained the problem. A newer version should be in the mail shortly. I’ll let you know how it goes. Looks like the company has good support :)
I also managed to convince the Ramachandran lab that the new 14 channel Emotiv Epoc is the way to go. We will be ordering the research...

Research with a Business Mindset
I am coming closer to something that I have had started realizing in an earlier post. Research is business. Business is time, money, people, and results.
Investors are grant money. Products are publications. Data are company investments. Data are company property. Scientists are CEOs. Labs are corporations.
For instance: Always get permission from the PI before accessing data. The CEO controls...

Woooo Finished the New Effort IRB!!!
3 days, 20 hours, and 8 pages, its a beauty. I must have rewrote each sentence close to 3 times. When you write this sort of document, you are forced to clean and linearize all of your ideas. Doing this was not easy, and I was forced to face some deep theoretical issues that have escaped me in the past months. However, tonight I was able to tackle them head on and draw new distinctions that I...

Paulus Lab Website Coded!
Whew! This is my first fully php website. Its way cleaner and more efficient to use php. Each page renders the entire “theme” (all the links, images, css, html) in only 5 lines!! Now thats lightweight coding. I need to make the flash part next.

Worked on it over the past 2 days, which is about 10 hours..
WatchThis is a video on how body parts are grown with stem cells. There are 2 strategies:
Build a part from scratch (using a mold)
Make the body regrow its own parts (with a chemical that fetuses use to regrow parts before birth)
I highly recommend watching this. It is the future of medicine as we know it.
Props to Robert Koehler for sharing this!

Sensation Seeking Application Finished!!!
Thats right, I stayed up all night. 839 lines of code later, I finished the php script that scores Zuckerman’s Sensation Seeking Scale (SSS). The SSS is a neat inventory that basically quantifies how gnarly you are. Zuckerman (1979) has a different percentile distribution because he had a different sample size, it was a different era, and he was in Europe. Dr. Paulus has resampled his...
Super Simple AS3 Webcam Uploader
This here script does what everybody’s been looking for. A simple flash webcam app that uploads images from your webcam to the web. It also lets you download the image you just took.
Here’s a working demo.
Here’s the source files.
Here’s how it works:
The flash code creates the camera and takes the picture as bitmapdata
This bitmapdata is fed into a jpeg encoder (in...
