Lenovo 3000 N200 sound card problem solved

My Laptop is a lenovo 3000 N200.After i installed Ubuntu 8.04 my sound car was not detected by the system.
And also there were no software to test my finger print reader.

To fix the sound card problem in Lenovo 3000 N200 what i did was

1. open alsa-base file in the /etc/modprobe.d directory using a text editor

eg: $sudo vim /etc/modprobe.d/alsa-base

2 .then add following line to the end of that file

options snd-hda-intel model=lenovo
(and saved the file)

3.Open a empty text space and add the same line to that and save it as modprobe.conf in /etc/ directory and /etc/modutils/ directory

then i saved the files and restart the machine

finally i heard the sweeeeeeet Ubuntu starting sound........Cooooool
My next step is to find a fingerprint reader software for my fp reader....

2. open source.list file in a text editor (you must set the R/W active to the file before that)

3 Add following two lines to the end of the file

deb hardy main
deb-src hardy main

and save the file

4. type apt-get update in the terminal (Better do it as the root)

5.Then update manager will appier in the task bar( its a arrow directing down direction to indicate download)

6.DO the update and restart the machine with modem connected.

7.go to system->preferences -> network configuration to configure the connection

if you do not have a internet connection ,

Mobile Train TimeTable for Srilanka

For my Level 3 programming project I did a train time table management system which enables the Users to view train details through mobile phone and a web interface.while the train staff is able to keep the train time table upto date by adding ,removing,editing ,posting delays ect..

This was a solution provided for a current Sri Lanken problem where no existing solutions are there.
It is a extendible system which was designed and implemented using MVC architecture.As a result of that the system is easily convertible to the new technologies.
