I own a Logitech c170 web-cam which has very good Linux support. I bought this web-cam almost 2 years ago and at that time, it worked like a charm on Ubuntu 12.04. I stopped using the web-cam over a year ago and I almost forgot about it. A few days ago, I had an interview on Skype and as my phone front camera does not work well with Skype, I needed to take this one from my Desktop. So I took the web-cam and plugged it in to my computer running Ubuntu 14.04 (yes, I upgraded), launched Cheese (comes pre-installed on Ubuntu 14.04) hoping everything would work just as before. But to my surprise, even though I could take photos using Cheese, I could not see the video stream. Here's what I did to solve the problem:

Subclipse is an Eclipse Team Provider plug-in providing support for Subversion within the Eclipse IDE. Installing Subeclipse plug-in in Eclipse running on Ubuntu (or any other Linux distribution) is a little more complex than on win-32 platform. You need to install an additional package that contains the JavaHL binaries. To install Subeclipse, follow the below simple steps:

1.Go to Ubuntu Software Center and install the below package.

libsvn-java

2.Note the installed version of the above package.

Users of Alliance or similar broadband services might have noticed that their network connection would sometimes get dropped while on Ubuntu or the network speed is somewhat less than what is advertised. The solution for this is that you need to change the duplex setting of your network connection. Don't freak out yet, it's not as hard as you might think. Follow the below simple steps:

1. Get the desired duplex settings from your service provider. In this case, we will assume that it's "10 duplex half". Replace it with the appropriate speed in your case.

I have been brushing up my skills in Python from last week. I am a Java developer by profession and my love for Python came purely from a hobby perspective. But nevertheless, love is love. First time I learnt Python when I was still not that into Java and the Python version was 2.x. But this time, I went with the version 3.x.
I am also learning how to make GUI application with PyGObject since PyGtk is not used in new development anymore. This is some amazing work by the developers that I don't have to work in C++ to make GTK+ applications. My next goal is to make my first application in Python and GTK+, albeit a simple one, which I might publish also.

I upgraded my Ubuntu from 12.04. Eclipse 3.7 with Subclipse 1.6 was installed in 12.04. Now after upgrading to 13.04, after I start Eclipse and synchronize my project with the repository, it throws the error message: "Incompatible JavaHL library loaded. 1.6.x or later required."

Possible reason: libsvn-java is needed to be installed in Ubuntu in order to make SVN work in Eclipse. The installed version in Ubuntu 12.04 was 1.6 as far as I remember. But after upgrading to 13.04, the libsvn-java version was also upgraded to 1.7. But the version of Subclipse that is compatible with libsvn-java 1.7 is Subclipse 1.8.
