I am currently doing one project about Mobile Robot Teleoperation, so stream video over network is one of my part. Actually there are many different approaches, but I chose OpenCV as my main approach because of its advantages in term of Computer Vision. But the crazy thing I have to do is making 2 server and client programs which run in Windows and Linux, respectively. Ok, now let’s go together:

Install OpenCV

I am doing a project about Mobile Robot Teleoperation which uses OpenCV for Computer Vision, but I always get error: libdc1394 error: Failed to initialize libdc1394

The reason is: There is no file /dev/raw1394 since the raw1394 driver is not loaded. So you need to insert that driver:

$ sudo modprobe raw1394

Check your permission access to that dev file:

$ ls -la /dev/raw1394

I am usually using Facebook and Twitter together, so sometimes I feel lazy to post what I am doing to both Facebook and Twitter so I was always looking for a good application which can automatically post my Twitter Updates to Facebook. Finally I was so satisfied with this Twitter application.

But by time it is really annoying that every my Twitter updates show up in Facebook, and my friends always said I am a spammer ^-^, but couldn’t know how to prevent it to steal my updates until today.

What do you have to do ?

I am a Twitter fan so far, so I have been always looking for good enough tools to make up my Twitter background. Today, after working, just spent little time I can have a overview of those tools, thanks to hongkiat.com article.

Is the default blue background of your Twitter page starting to look stale, or is it just me? It’s time to spice up your Twitter page with a little more personality – a little more YOU! With the growing trend of Twitter usage, it’s only logical to treat Twitter as an impression of yourself. And as you would personalize the profile picture of your Facebook, why leave your Twitter as one of the faceless crowd?

Just choose one suitable tool for you from here

For me, I choose http://www.freetwitterdesigner.com to design my background. That online tool works like a online Photoshop program, so I can easily design make my own background. Just have a look http://twitter.com/ngohaibac
