E K Janaki Ammal

June 10, 2007

The latest issue of Resonance carries a biographical sketch of EK Janaki Ammal, a botanist (pdf); though the sketch mentions that Ammal was elected to be a fellow of the Indian Academy of Sciences the year the academy was founded by Sir C V Raman, namely, in 1935, from this document, it is clear that she is actually one of the founding members of the academy (and, hence the first woman member of the academy). Here is a note with her photograph (pdf). Unfortunately, there does not seem to be much of information on her on the net (and, no wiki page too, though she is listed as an eminent Ezhava).

Some links (to and via economists, mostly)

Structure of the Linux kernel

June 10, 2007

Here is an introduction to Linux kernel and its structure; via /.:

The Linux® kernel is the core of a large and complex operating system, and while it’s huge, it is well organized in terms of subsystems and layers. In this article, you explore the general structure of the Linux kernel and get to know its major subsystems and core interfaces. Where possible, you get links to other IBM articles to help you dig deeper.

Here is an online book about how Linux kernel works:

This book does not make any assumptions about the knowledge or experience of the reader. I believe that interest in the subject matter will encourage a process of self education where neccessary. That said, a degree of familiarity with computers, preferably the PC will help the reader derive real benefit from the material, as will some knowledge of the C programming language.

Finally, an online Linux kernel resources page.

HowTo: Write and submit papers

June 10, 2007

Though meant for mathematicians, some of the advice is valid for any paper writing–the one about writing a rapid prototype, or the one about submitting for the relevant journal, for example.

I also learnt another trick from my thesis advisor–namely, put every thought that occurs to you, everything you did, and every figure, explanation and derivation on paper. Then prune the draft; move things around; remove sections; edit vigorously; prune some more; work on something else for a couple of days, and get back to the draft; prune, and prune and prune. The only thing to remember while doing all this is not to delete anything permanently. Works wonderfully!

Terence also lists some resources at the end of his post; I would add Knuth et al’s Mathematical Writing (pdf), and Steven G Krantz’s wonderful primer on the subject to the list–by the way, Halmos’ review of Krantz’s book is here (pdf).

Before I end this post, I should also link to this career advice page of Terence Tao–again, mostly for mathematicians, but some points are of more general interest.

Have fun!
