Killing a process in Linux

As a software developer one thing I have several times is killing a process, some people will term is as ugly or bad, but general software developers often come across situation where killing a process is handy or necessary. I will mention some use cases later in the blog. Killing a process usually involves 2 steps. Finding the process ID that is intended to be terminated and terminating it with a kill statement.

Guarding against softwares with memory leak

I have been using IntelliJ IDEA as the IDE for my project development. It has been satisfying but sometimes it annoys me a lot. For example, when I am typing in the code editor and all of a sudden I cant hear the music playing (which I always play while coding), the IDE stopped responding and the mouse pointer hardly moves. The only way to start working normally again is to restart my laptop and on a laptop it is not a happy scenario to force reboot and moreover I do not like force reboot as a solution.

WinRAR on Ubuntu

As a novice Linux and Ubuntu Fiesty Fawn user I have faced some issues related to RAR Archives. WinRAR is the Windows tool widely used for this purpose and it is also a powerful archiver.

This actually leads to 3 challenges - generating DDLs for the DBMS, keeping the queries in Data Access Layer portable across the DBMS platforms and optimizing the read SQLs for the specific DBMS platform. This blog entry will cover only introduce the probable solution to the first of the three challenges. DDL usually differs from one DBMS to the other.

Getting Intel 82801G to work in Fiesty Fawn

My new laptop is a Acer Aspire 5585WXMi. It ships with ALC883 Intel HDA chipset. I could get everything to work with Ubuntu Fiesty Fawn except for my sound card and it was so sad that I could basically work with everything excepting for sound. After trying a lot of things all of a sudden it started to work. So I started looking into why and how. I noticed that I have ALSA 1.
