Install gtk-gnutella 1.0.0 in Ubuntu 13.10/13.04/12.04/10.04

Last updated: September 24, 2013

Gtk-gnutella is the graphical Unix Gnutella client, efficient, reliable and fast, written in C. It has been optimized for speed and scalability, with low-memory consumption. It is meant to be left running 24×7, using little CPU and only the configured bandwidth.

Gtk-gnutella 1.0.0 is a major release correcting a few bugs and adding small but interesting features such as the ability to limit dropping of received UDP messages, making the DHT keys and values persistent across sessions, SDBM file auto-compaction at startup, and last but not least, rarest-chunk downloading to optimize download efficiency when facing partial sources.

New Feature:

Let users define a maximum lease time for UPnP and NAT-PMP mappings.
Made DHT keys and values persistent across sessions.
When there are partial sources for a file, download the rarest chunks first.

Improvements:

[GTK1] Optimize massive updating of the download source list.
[GTK] Dynamically update the list of available chunks in the file (blue line).
Files used to persist information across sessions are now auto-compacted.
The UPnP layer can now monitor more types of Internet Gateway Devices.
After unclean shutdown, rename existing core file in crash directory.
Detect servers that choke when receiving pipelined HTTP requests.
Added the Mersenne Twister Pseudo-Random Number Generator.
Remember when user requests an auto-restart, to keep the same session going.
Increased maximum download buffer size to 1 MiB and default to 128 KiB.

Install gtk-gnutella 1.0.0 via PPA:

The Sourceforge provides the Deb packages for gtk-gnutella, but I can’t install it on my machine due to dependency problem. Fortunately there’s a PPA repository makes it easy to install it in Ubuntu and its derivatives.

To get started, press Ctrl+Alt+T on your keyboard to open terminal. When it opens, run below command to add the ppa:

sudo add-apt-repository -y ppa:zapman/gtkg

Then update package lists and install the package via:

sudo apt-get update; sudo apt-get install gtk-gnutella

Enjoy!

How to easily kill a frozen / locked-up app or window in Ubuntu

Last updated: September 23, 2013

This tutorial shows you how to easily kill / force quit an application or window that freezes or stops responding using xkill & shortcut key.

Xkill is a utility for forcing the X server to close connections to clients. This program is very dangerous, but is useful for aborting programs that have displayed undesired windows on a user’s screen. It works on Ubuntu, Linux Mint, Elementary OS, and other Linux systems.

You can run Xkill from terminal, Alt+F2 run command box or even via a keyboard shortcut. When it runs, your cursor becomes a cross (‘X’). Click on any window will kill it instantly.

Warning: Don’t click on Desktop and Panel when running xkill, it will also kill them and break your desktop and you need to restart to restore.

To create a shortcut key for xkill, go to System Settings -> Keyboard -> Shortcut -> Custom shortcuts. Click add to create the shortcut and give a key combination.

After that, press the key combination and then click on the window you want to kill.

Enjoy!

This tutorial is going to show you a simple and stylish Facebook browser for your PC. This app provides native Facebook experience in a Facebook styled window plus a system tray icon for providing notifications. This app doesn’t disturbs you by popping out notifications, but it notifies you silently by changing the system tray icon color.

This app uses a simple approach for delivering notifications in the system tray. It reads the number of notifications, messages and friend requests directly from the facebook page, using Javascript calls, without using any components from Facebook SDK.
