I’m trying something new today: a small experiment falling in between programming and scientific litterature.

I’ve been interested in “literate programming” for quite some time now, without going any further though. But I recently found the tools that would make it actually practicable and decided to dive in.

So, I’ve implemented a very small Python module that illustrates the notion of autocovariance and autocorrelation and the way to compute them via Fourier transforms:

Literate Musing > Autocorrelations

The subject is not new at all, but such measures are something that I had to re-implement (for image processing puproses) more than I’d like to in past years, and each possible implementation having its own statistical biases, it always takes time to remember all the tricky details. So, this new document should at least help (me) quickly find all the relevant info.

This was also a subject underpinning a big part of my PhD work… a PhD that I defended 2 years ago, is there some “causation” here ?

:)

For the technical side of things, the “tools” that helped me setup this “experiment” are essentially:

• Python
• pylit
• sphinx

Since Miro2.0 has been released a few weeks ago, I’ve had some time to use it and I thought I could take this occasion to share some of the podcasts I folow regularly on the internet.

But first of all a great thanx to Miro’s developer that did a great job in tackling the two major problems I had with the software: impossibility to navigate the list of feeds, while playing a video (or audio) and performance. The only remaining thing on my whishlist would be that Miro handles image feeds (ala CoolIris for instance).

Now for the list of podcasts I listen to, most of them are in french, so here is a quick selection among the english speaking ones:

• ESOCast some info on the southern observatory in Chile
• Martin Bailey Photography Podcast: nice podcast about Martin’s work

• Jeff Curto’s Camera Position : about the “creative side” of photography

• TED Theme: Tales of Invention : high-tech fancy conferences
