Getting Wireless to work on Lenovo Thinkpad T400 with Ubuntu 10.4 Lucid

I struggled for a while to get my wireless card work after installing / upgrading Ubuntu on my T400 Thinkpad.

My T400 came with wireless card : Realtek Semiconductor .

To get it working, I followed these steps :

1- Open nautilus

sudo nautilus

2- Browse to /lib/modules/

3- Search for any rtl8192se and remove them

4-Download the drivers from Realtek website (Search for RTL8192SE)
Click to go to Realtek Website

5- Install the drivers

sudo apt-get install build-essential linux-source-2.6.32
tar -xzvf rtl8192se_linux_2.6.0015.0127.2010.tar.gz
cd rtl8192se_linux_2.6.0015.0127.2010
sudo make
sudo su
make install
modprobe r8192se_pci

6- Reboot and it should be working out of the box.

Installing Java plugin for Firefox on Ubuntu 10.4 (Lucid)

After upgrading from Ubuntu 9.10 to 10.4, I had some issues getting Java to work with Firefox, after checking the software center, I found that the Java plugin has been removed.

To get this fixed, I simply followed the steps in here http://ubuntuforums.org/showpost.php?p=9008918&postcount=32 and it worked well after that.

The world is going Mobile

Lately I have been spending a lot of time writing small apps for my nokia smartphone and willing to get iPhone for the same purpose. meanwhile We are working on a complete set of templates for a mobile version for all our 202 websites at work. and by chance A close friend is working on a wap gateway to server websites for mobiles. and Apple launched iPad !

All the above points is a live proof that the world is going mobile, reading that article here “The Whole World Is Going Mobile” and looking at the charts inside tells you where the next trend will be.

People will not have to carry a laptop, or sit in front of a screen, keyboard, speakers and case to just read the news, chat with friends, tweet, communicate on facebook, watch their favourite videos on youtube or play games. Simply they will do that using their mobile phones.

The small screen and keypad size is still a challenge, but there is large firms, and creative minds working on finding solutions to overcome those obstacles. and they do succeed.

Time now for the developers to master new areas, and designers to consider new audience.

Quick dive into Flash Builder 4 (formerly Flex)

It has been a while since I have opened Flash Builder 4 Beta, but having to fill in the survey for testing, I gave it another shot yesterday.

Downloaded the last build “253292” from adobe prerelease repository.

I spend like couple of hours reading the docs and trying this and that, there is a lot of improvements, but what really caught my eyes is the tooltip help when you mouse-over a component, it gives you a more detailed information than before.

And what really was a WOW for me is the changes in the Data menu, now with the simple wizard you can create a connection to web service, PHP, BlazeDs, and others.

I tried the PHP one, and it went very smooth, I could even without writing a single line of PHP, enter the database credentials, and select the table I want to have access to from my flex app, and in few click, flex created the service in PHP and the mirroring AS classes, It even downloaded the Zend Framework AMF component.

It is much different than before, I had to do a lot of hard coding to get to this point, now developers will have more time to concentrate on the application itself, rather than on connecting to database and making it work.

It is worth trying and developers should read the migration docs from previous versions to get ready for it when it released.

Manage your notes / Code snippets with Snippely

It has been a challenge for me to keep tracking code snippets I want to remember, I have always used text files, or sending my self email with the snippet that I feel I am gonna need to look at again in the future, same for notes also.

Today I have found this nice Air App called Snippely, it allow you to manage your notes / code snippets, It is enough for me and better than text files and emails, I believe I am gonna stick to it for now.

Snippely

Only Two options I wish to see in the coming version, to backup / restore the data & to sync the data across many machines, but like I said, I am happy with what I have now.

You can get Snippely from their Google Code page : http://code.google.com/p/snippely/

I hope you will find it as much useful as I did.

How to Add & Subtract time code in Python

I have been developing some tools for the media production lately, i found a neat way to add or subtract certain amount of seconds to a given time code.

for example i have a video that starts from 12:45:05 and i want to add 59 seconds to it and use the new time.

from datetime import datetime
from datetime import timedelta

time = datetime(2009, 1, 1, 12, 45, 05, 0)

diff = timedelta(seconds = 59)

final_time = time + diff
