Facing new challenges everyday

I recently had a problem where an entire website goes down from nothing, I checked the Apache logs, the application server logs and no big exceptions has been found.

After check the postgres database logs and few hours of searches on the web I finally could think in a small possibility, the firewall closing idle connections opened by application servers, so I decided to set the tcpKeepAlive property on JDBC connection, after that the issue seens to be gone.

I have been trying to find a reason to study c programming for a long time, now I found a reason to do it, I wrote a very small application that uses APR and GTK+ where I can manager costumers and suppliers contact info.

Before start coding you must pay attention to the following requirements:

• Apache APR
• GTK+
• pkg-config

All the requirements above can be easily installed in your system by using the linux distribution package management system, you can also visit their respective sites to download the sources, compile them and install the binaries. The Apache APR sources can be found at apr.apache.org and GTK+ sources at gtk.org
