Tune your iTouch

The iTouch as it is after you buy it doesn´t worth the money it cost, but after some work tunning it, this nice device begins to blossom. But keep something in mind, without wifi connection to internet your iTouch won´t evolve.

Norma43 bank format parser

In Spain, all banks has an unified file format to supply statements of account, this format is known as Norma43. The first version of the format was released May 1982 and it's quite simple to parse. Almost all bank's web supplies Norma43 files with your account info. If you want to process this info, inserted in a database or whatever software treatment, this file can be very helpful. I've implemented a python class that parses this file format and fill in an array with all the registers in the file and its field values.

SSH editing & WinSCP

1. Do you want to edit files on your remote linux server from your windows desktop using your favorite editor (Crimson Editor may be)?
2. Have your linux server already an SSH server properly configured?
3. Is your linux configuration mana low?(WOW addicts will understand this question)
4. If you have answered YES to all the former questions, this blog entry may be helpful for you.

After several internet searches I found that the free software, WinSCP, the one that I use to copy files from/to linux, currently support this feature for any editor and also works great with Crimson editor, enabling remote editing almost transparently. When you edit a remote file, it opens one temporary file in your local machine and monitors the file status, updating the remote file when any change is detected.

MtgLife returns

Finally I rescued from backups the code of the MgtLife, a Python application I developed a year or two ago for Symbian. The main purpose of this application is to keep updated the life points of the two opponents of a Magic The Gathering match. This is what I call a freak combo, Magic + CellPhone + PyS60.

Debian Etch + Quickcam Chat

This is the key feature for my next sad and freak project. I need a webcam working on my linux server. I've failed several times to configure it properly, but I finally achieved it. Here you will find how to configure a Logitech Quickcam Chat on an Etch Debian.

Correlating Data

After analyzing any measurement values I always ask myself the same question, is this data wrong or not?. To check if my temperature measurements were good enough I gathered in all the thermometers in my home and placed next to the Arduino+LM35. Then I confirmed that the LM35 was doing a good job, but that wasn´t enough, I needed to know if the measurement of the LM35 could be at least a naive model of the whole room temperature. To do so I started working with PyEphem and probed that the temperature data was correlated with the sun altitude.

Plotting Data

Data is almost useless without a proper view. After storing the temperature data I need a way to plot this information so I can infer something. Let´s face the 'artistic' stage of the project.
