You've Landed Here Because of My Retweet

You must have clicked on a link in a retweet that bring you here. The retweet starts with 'RTL', which stands for 'retweet with link', and ends with a link pointing here. This has nothing to do with the content or the author of the tweet that I reweeted. You may want to learn more about retweet with link here.

If you have landed here not because of a retweet then you may want to search Twitter with keywords 'RTL @chelahmy' where this link appears on those retweets. Generally this link is shortened on those retweets.

Why I place this link when I retweet?

I do this because I want to promote my blog. I don't blog that often. I am a software programmer and right now I am programming around Twitter. You may find that most of my blogs are about my ideas around Twitter. I would like to write about my programming in Twitter but that may come once in a while. Ideas will come more often. There is not much different in term of process to come up with an idea and to come up with a software program. Both require logical thinking. Please have a look at my blog archive at the left side of this page. Anyway, welcome to my blog!

Setting Up PyScripter for Quantum GIS

PyScripter is a general purpose Python Integrated Development Environment (IDE). Quantum GIS (QGIS) is a desktop GIS application that can be extended with Python plugins. Both are open source softwares. We intend to use PyScripter as an IDE to build QGIS Python plugin. We are using PyScripter 2.4.1.0 and QGIS 1.6.0 in Windows. PyScripter does not come with Python. On the other hand, QGIS is built in with Python. Thus, we will setup up PyScripter to use the build in Python in QGIS. We assume both PyScripter and QGIS are already installed. Preparing PyScripter batch file We assume that QGIS is installed in C:\OSGeo4W\ folder and PyScripter is installed in C:\Program Files\PyScripter\ . 1. Copy qgis.bat in C:\OSGeo4W\ bin to pyscripter.bat 2. Edit pyscripter.bat to remove the last line that read something like this start "Quantum GIS" /B "%OSGEO4W_ROOT%"\apps\qgis\bin\qgis.exe %* and replace it with this in one line Start "PyScripter" /B "C:\Progr...

Access Control

Access control is about controlling user flow within your application. Do not mistaken access control with security which is a bigger subject in itself. Access control begins by authenticating user and limit his or her activity in your application. An activity is something like creating, updating or deleting a content. There are always finite number of activities that can be done in a given application. Each user can be assigned to a set of activities that he or she is allowed to do. Access control is usually tied to session management. However, you do not need session management to have access control. When a user log in, a session is created so that the user is remembered for the subsequent access. Otherwise the user has to keep on providing his or her credential for each access. We can also keep a list of activities that the user is allowed to do in the session record. Some applications let the session alive indefinitely and some applications time out user after a duration of inacti...

Separation of Front-end and Back-end Concerns

Separation of concerns is the cornerstone of MVC framework. Model, view and controller are three broad concerns of web-based software development. On its early days MVC was implemented on server side. The server renders views for clients. Nowadays, most clients render views themselves. Even the terminology of client-server has already morphed into front-end and back-end . The need for back-end to handle views is diminishing. View concerns have became increasingly complex with two big sub-concerns of aesthetic and dynamics. Front-end evolves into bigger MVC concerns of itself. While back-end evolves into larger modeling concerns. Now, front-end and back-end are two separate concerns. Front-end and back-end are handled by two different teams of software developers with different specialties. Back-end evolves into something like "dinner can be served even without plates, forks and spoons, without table and chairs, and without a dinning room." Front-end is serving the withouts....
