From (broken) KMail to Evolution (or from maildir to mailbox)

If you are looking for a rant about how Evolution is better than KMail, look elsewhere. I am running Evolution because I am giving Gnome another chance and I like using all the standard tools to get an integrated desktop.

Programming Python, Part I

Linux Journal has just published an article I wrote title Programming Python, Part I. It is obviously an honour to have an article on such an important publication.

Thank you Ramiro for letting me know it was already published and write about it. Continue reading “Programming Python, Part I”

Tramp

I have just learned about Tramp. An extension to Emacs that let’s you edit file remotely. Very nice. Kate can also do it through the fish KIO, but sometimes Emacs is such a good editor.

If you normally edit files on remote server and you like Emacs, check Tramp. I don’t have special attachment to any editor yet and I really can’t make full use of any of Vim or Emacs (the two editors I use most). I think I should sit down for a couple of weeks and learn Emacs.

SVGs in .Net using Cairo and Gtk+ (and C#)

If I was using C it would have been simply a couple of calls to librsvg, but on C# things got a bit more ugly because Rsvg, the wrapper around librsvg is not finished. And other bindings are also missing. Just getting a Cairo context out of a Gtk.DrawingArea was not as simple as I would have liked it to be (I describe how to do it in a previous post, but I’ll do it again here).

The archer aims at himself

Last Monday I took my first lesson in archery, that is, shooting arrows with a bow. Some years ago I would have tried to do it myself: go buy a bow and some arrows, find a place to shoot and shoot. But I am really glad I haven’t done that and instead, went to Otendor’s Parlemo branch. There’s so much to learn first. On one side there’s a lot of technique. A lot. I wouldn’t have guessed a 10% of what I’ve been taught in one lesson.

Trying to find exceptions in Haskell

In my quest to re-learn Haskell I eventually thought: “OK, let’s see how an exception looks like”. Starting my favorite interactive Haskell implementation:

   ___         ___ _
  / _ \ /\  /\/ __(_)
 / /_\// /_/ / /  | |      GHC Interactive, version 6.4.1, for Haskell 98.
/ /_\\/ __  / /___| |      http://www.haskell.org/ghc/
\____/\/ /_/\____/|_|      Type :? for help.

Loading package base-1.0 ... linking ... done.
Prelude>

OK. Let’s generate an exception now, a division by zero for example (something basic): Continue reading “Trying to find exceptions in Haskell”

Django… awesome

I have an idea for a web application that might enjoy moderate success. And from time to time I try to develop it and it would be already done if it wasn’t that web developing is so painful (reading PLAI and trying to make my own Lisp to conquer the word is far more fun and entretaining… oh damn, I shouldn’t told you my plan… oh well).

My favourite framework so far is (and continues to be, more on that latter): UnCommon Web (UCW). But after reading an article titled Framework Performance (or Django vs. Rails vs. Symfony: Django is fastest on digg) I said: “Hey, let’s give this Django thing a try”.
