MultiGet – a multithread download manager for Ubuntu Linux desktop

It’s extremely frustrating to have your download progress interrupted, especially when you are downloading several (relatively large) files over the Internet. Fortunately, there’s MultiGet, a download manager that supports multi-connection and parallel downloads.

MultiGet is easy to user, and from my observation, it’s interface closely resemble Flashget download manager from Microsoft Windows platform. The differences is, that MultiGet runs natively on Linux, and it supports multiple operating system too.

MultiGet has a simple, friendly user interface that is easy to use. Best of all, it supports batch task downloading.

Working hard publishing papers and learning PyGTK

For the last few weeks I’ve been working hard to finish up my research project, most of it concerning about on mobile phone application usability and context-aware applications. This leaves me with less  time to devote for this blog and I started to realise that I might have a ‘burn-out’ issue at the same time.

I’m still using Ubuntu in my daily work if you are curious (Ubuntu Netbook Remix 9.04 for netbook) and Ubuntu Jaunty Jackalope for my Intel Core 2 Duo Desktop PC. Besides writing those research papers, I’ve use what left of my time to learn PyGTK to enable me to code RAD app for GNU/Linux desktop environment.

I found out the references around the internet regarding PyGTK is very helpful to aid me in understanding the GTK+ bindings in python, which is not much different from its C counterpart.

Now that I’ve some time to spare until Hari Raya, I’ll try to use that time wisely to fill up this blog with a couple more of fresh new posts. So, keep reading!
