Meebo web interface: I recently started using Meebo, an online browser-based instant messaging. Meebo allows users to combine instant messaging on a single webpage. Meebo works with several chat networks: AIM, Yahoo!, MSN, Google Talk, ICQ and Jabber.

There is no software to install. Meebo will run on any computer with a browser and internet access. Meebo allows users to combine chat buddies in a singe buddy list. You can use your existing IM accounts, or get a free Meebo login to chat across all networks with a single id.

The Meebo interface is also capable of playing games, video conference, transfer files, and so much more, all from the web browser. There is another feature is called Rocket man, it’s a shiny rocket ship in the Meebo IM window which allows you to launch and select any application to launch with your buddy.

In addition to the web interface, Meebo has other products and offerings.

Meebo Me: is a piece of code that you place in your web page. It allows you to chat with anyone who comes to your blog or web page. Your visitors show up in your Meebo buddylist so you can strike up a conversation, answer questions, or just keep tabs on guests. You can also publish your online status so friends can see if you’re available when they visit your site.

Meebo for iPhone: Meebo brings IM to the Apple iPhone. Just point to www.meebo.com on the iPhone or iPod touch and chat on the go. Effortlessly flick through your buddies. The smart buddylist makes it easy to keep up with all your conversations. No downloads are required and it’s free.

The Meebo Firefox Extension gives you a sidebar with a smart buddylist and visual notifications when your friends IM you. Drag internet links and images directly to your buddies, all while surfing the Web!

Meebo Repeater: Meebo Repeater is a software download for people who want to chat safely when their IM access is restricted. Just install the repeater on a computer that can access the Web freely, and then use that computer to bounce the signal to Meebo. It’s simple and secure.

Linux Kill Command

Occasionally, a Linux Kill command is what you need to terminate an application. This happened to me last night. I was trying to re-run Firefox 3.0 after it had crashed. I was getting an unusual error which I’ve never witnessed before. I wished I had taken a screenshot of the error since I can’t remember it vis-a-vis. It said something like this, “Firefox is still running, please close the application before running another one.”

It was very unusual error since I could not find a trace of Firefox running on my desktop. There were no minimized windows, no instances of Firefox running whatsoever in the current panel I was in or in any other panel (Ubuntu has multiple panels). Zilch. Absolutely nothing, but my system still thinks Firefox is running.

Force Quit

One way of killing an application is to use Force Quit. You can add a force quit icon to your Top Panel by right clicking your Top Panel and selecting `Add To Panel.` Look for the `Force Quit` icon (it’s the broken window icon) and click Add. You should see a `Force Quit` icon on your Top Panel similar to the snapshot I’ve taken below. It’s the last icon to the right, the one that looks like a broken window.

Kill Command

In my case, I could not use Force Quit. There were no traces of Firefox running on my desktop. Well, it is time for the Kill command. So, I thought about writing a tutorial for Linux newbies on how to terminate an application that will not start because another instance of it is running in the background.

The Fix

First things first, check if there is a process running in the background. Substitute the name of the offending application in place of Firefox. From the Terminal, type:

# ps -ef | grep firefox

The PS command gives you a snapshot of the current processes running on your system. I’m using the GREP command to display Firefox processes only. You should get a reply similar to the one below.

In this example, we are seeing one process with Firefox running. It has a process ID or PID of 4694. The second process is the GREP command we just issued. Just ignore this one. Based on the PS command, we’ve now determined the PID of the application that we need to KILL.

Going For The Kill

Now, for the fun part. Let’s kill this application. From the terminal, type:

# kill 4694

You can try it with -9 to ensure execution.

# kill -9 4694

That’s it. This application is now dead. You should be able to restart the application. To learn more about Linux commands, check out the following Man pages:
