3 years of work on Pipenv in Gentoo come to a happy end
3 years and 3 months ago, I signed up for maintaining Pipenv in Gentoo. This work made me co-maintainer of pipenv. I finally closed a long standing bug in Gentoo's pipenv. Due to this work, pipenv now ships less vendored packages, and is about 20% smaller in size.

coverage reporting and logging without a webservice
For quite a while now I wanted to have a cheap replacement for collecting and tracking coverage of codes I work on. Finally, I found a nice way to record and track coverage reporting inside git itself in a semi-automatic or completely automatic way.
On learning Ruby coming from Python ...
I am learning Ruby, and coming from Python it's not a an easy thing. Ruby is confusing, it has a weird syntax, and things are not really simple as in Python. There is still tons of stuff which seem like dark magic. There's `nil`, there are `gems` and `bundler`. And there is _Rails, which isn't Ruby_. Ruby is good for so many people out there, and I am sure you can do amazing things in it. I already know it's never going to be my weapon of choice, but it's not bad knowing my way around it. I'd like to know how to set up a simple project, read and debug code, install gems and package ruby projects. I have been ignoring Ruby for too long.

Yet another case of Python vs. Regular Expressions
Regular Expressions are really awesome, and If you read the last post you might got the wrong impression I am totally against their use. I love using regular expressions, but sometimes, knowing Python is more than enough.
Python's regex is not always the best option
When programming in Python, regex are not always your best tool. This has a few reasons, regex can be computationally expensive, unreadable and unmaintainble, and finally, sometimes there is a better pythonic way without them. Here are a few examples.

A Complete PyGTK CD Ripper Tutorial
Most tutorials on GTK, create partial UIs, and thus leave the reader to connect the rest by himself. Some others create an almost complete application, but usually, this application is useless. This tutorial, will lead (eventually, I hope...) to a functional application, that rips CD and converts them to MP3 using cdparanoia and lame. In addition to writing this tutorial in blog posts with code, the code will be highly verbose and commented thoroughly ...

Warning: This is not a technical post, rather just a boring rant and a call for advice. A friend of mine asked me what programming language he should learn.
A Usefull PyGTK Example
I have been looking for a good pygtk tutorial for a very long time. I have found a few tutorials which where an overkill, so I don't link to them.

oh, Yesterday I was a bad programmer
Forgetting my first lesson in programming, I looked for a solution to convert IP addresses to country. I found out tables, and SQL files, and went on and on trying to figure how to use them, and do SQL in python
Installing python-matplotlib from source in Debian
Hoora Debian ! I love how every past experience of developers brings something useful ! If you need to build python matplotlib from sources you need to install quite a lot dependencies. Luckily for me in Debian it's quite easy.

Most people that find my blog in the end of the internet arrive here while looking for python matplotlib tutorial. That's thanks to the crazy matplotlib tutorial I already have in my blog. However, this tutorial is not very useful. And since I'm using matplotlib to do some of my homeworks, I been wanting to post some real life tutorial. After all why not give the audience what it wants?
Crazy Matplotlib tutorial
I started using python's matplotlib to plot graphs in my Oceanography courses. Matplotlib is pretty easy to understand if you already know some python. However it's documentation is somewhat frustrating, even though it comes with a plethora of examples.
Data analysis with Programming
Last time I wrote about the disadventages of using a spreadsheet program to analyze large amounts of data, espcially when it comes to important data.
Data analysis with spreadsheets vs. programming
In many cases people use programs like Excel, Gnumeric or Openoffice.org spreadsheet to analyze large amounts of data. I always hated Excel, and when I switched to Linux about 3 years ago I learned about Gnumeric, but I always found it a little bit limited because I couldn't use macros.
