These days I’ve been busy programming a version of Lavaurs algorithm for the idenfication of circle chords: the abstract Mandelbrot set.
The images don’t look like much, but the output of the program is nicer: it outputs an Encapsulated PostScript file which looks sharper. But when converting to png with ImageMagick some distortion appeared.

Sometimes I view mathematical knowledge as a desert. Full of sand, some pebbles, some rocks. You can get easily lost in this dry sea, but you can also find a place to stay and add. And now, I can say I have added my small grain of sand: An entire transcendental family with a persistent Siegel disc (link to the preprint version in ArXiV). My first article, now officially “Awaiting Editorial Assistant Processing”.

Like almost every year, August comes with a lot of pending To Do lists… This year, it is choking full, mostly of work related issues, and some unknotted threads waiting to be finished. And in two and a half weeks I’ll head for Paris, and then my “vacation” is over.
Yesterday I wasted my morning: bought my orange belt, set up the external monitor for my netbook, configured the printer, fotocopied two pages of a book and drank an horchata with a friend.
I love the smell of old (really old, but not dusty) books. It reminds me of some kind of vanilla scent, that is only to be found in them. I smelled it a few weeks ago, when I bought Conrad’s Heart of Darkness, second hand 1972 Penguin Modern Classics edition (3€) in a second hand bookstore in Göttingen (Germany).
Here are some pictures and images which look pretty good together with my Fluxbox configuration, in my Netbook. Here they are for your enjoyment. They are supposed to be small, not to drain too many system resources. I will upload later the butterfly in higher resolution.

Two and a half weeks ago, I got a netbook and promptly installed Ubuntu, followed by Fluxbox (as already explained). And after two weeks of almost continued use, I like it even more than when I decided to use it. Some of the points I really enjoy (in no particular order).
Strong keyboard shortcuts. As an emacs junkie as I am, I love keyboard shortcuts. And Fluxbox is incredibly flexible in defining or removing them: Even system-wide shortcuts are customizable.
