Rascase, a very simple tool

I've not talk much about Rascase here, but now i'm gonna explain some things where i am working on.

Rascase is mainly two things, the first one 'is my project degree to obtain my title degree of ingeniero ejecución en computación e informática (aka computer engineer)', and the second one 'is a simple CASE tool for linux to design Entity-Relationship models'.

Currently I am finishing the document to present it for corrections, these are made by a group of designed teachers (correctors teachers), they will return it to me on march (probably at the end of march), then a apply the corrections to the document and then wait for defend my project.
On the software side, rascase currently is less than a drawing program, still there is a lot of things hardcoded, but in february it must be functional tool, a really CASE tool.

Rascase will use the philosophy 'just to use', because the time don't let me develop a complete and powerfull tool like 'powerdesigner' is, but this will be just a stop on the road, i mean this will be just the first release (and i hope not the last to), my expectations are huge :)

A few thecnical details about the technologies involved in the development of the project:

• The interface is designed using glade (3.4), the are some parts made by code, especially the canvas setup and a minor details.
• The pattern design is MVC++, a MVC based pattern, defined by Ari Jaaksi (part of the development group of nokia internet tablet n770, n800, n810, and others things inside nokia)
• The programming language is Python :)
• Libraries used
• PyGTK, nothing to say about this :P
• PyODF, a python library to make documents with OpenDocument Format, i'm using it to generate the data dictionaries in ODT format
• PyGoocanvas, the bindings of goocanvas, and this is a canvas library is based in cairo
  


• The source code is managed using git, the great distributed version control system

A shot of the curently state of rascase, just a functional interface without logical code. (aka mockup of prototype :P)

WWE en Santiago de chile

Sí, al fin, la

WWF

WWE estará en Chile, 100% confirmado, tanto por el sitio oficial como por un weon (aka chileno) con mucha suerte que está en yankilandia y carreteó con los hardy boyz

La cosa será el 14 de febrero, en el arena santiago (la unica vez que he estado en ese domo fue para el partido de Chile-Argentina por copa davis y quedó la cagá :P), los precios variarán entre 20 y 130 lukas, las entradas las venderán por ticketmaster

espero poder ir :-\

alguien se anima?, esto probablemente no se vuelva a repetir, porque sacar un espectaculo así de grande al backyard del mundo es bastante difícil, basta con pensar con toda esa gran cantidad de cantantes/artistas que anuncian la venida a chile y luego a la altura de brasil o llegando a argentina anuncian que no vienen a chile, razones?, chile es un mercado demasiado cagón :-\

Herramienta para Diagramas de secuencia

Hoy me cansé de las herramientas pussy (aka ide-all-in-one-use-just-the-mouse) y comencé a utilizar una herramienta a lo menos poco usual, pues consiste en que el diagrama de secuencia lo programas, es decir, escribes la logica del diagrama y la herramienta se encarga generar la gráfica :) con eso me olvidé de esos problemas malditos de 'quedó un poco corrido', 'quedo desalineado', etc..

Una muestra del primer diagrama que hice y me tomó solamente unos 10 minutos, entre cranearme la lógica del diagrama de secuencias y aprender la sintaxis (que por cierto un muy pequeña)
con el siguiente script

Usuario:Actor
x:ViewMainWindow ":ViewMainWindow"
y:y ":ControlMainwindow"
z:z ":Project"
a:a ":ControlSaveFileDialog"
b:b ":ViewSaveFileDialog"

Usuario:x.Abrir Proyecto
x:models=y.open_project()
y:a.ControlSaveFileDialog()
a:path=b.ViewSavefileDialog
y:path=a.get_path()
y:z.new Project()
y:models=z.get_model_list()

Para obtener como resultado esto otro


Definitivamente una herramienta que apunta a la productividad.

100% recomendada, el sitio de la herramienta es: http://sdedit.sourceforge.net

A pesar de que está en Java con swing, me gustó caleta :) quizás podria algún día reescribirla en pygtk xD e integrarla a mi herramienta case :D alguien se anota para esa feature :P

Emacs recargado

I'm still fascinated with the power of Emacs, it's amazing how a big group of hackers (real hackers)could develop a wonderful multi purpose tool, especially oriented to programming tasks.

The key of emacs is elisp, a functional programming language (I really hate the functional languages, but this one it is not a pain-in-the-ass like SML).

I didn't read any elisp book or tutorial, but i could made some customizations of my environment, especially with the help of jonathan (a member of the rizoma-devel crew) and emacswiki.

Today i started to improve emacs for develop python scripts, and this is the result

That is a shot of a python script evaluated (at write-time) with pylint

Now if you are developing software, probably you will need the api documentation, wel with emacs you can have the python help embedded in the main window, so if you are on a word with simple customizable shortcut you can display it like in the image:


There are another tricks that I applied to my .emacs file, i'll let them available in some website soon.
