There are many applications out there that provide project-based web development tools and very feature-rich interfaces, but sometimes all you really need is a good text editor. For those times, there are few editors that can stand up to the KDE powerhouse called Kate.

Kate is a multi-document interface (MDI) text editor, available for both KDE 3 and 4. It runs on multiple Linux and Unix-like platforms, Mac OS X, and  Windows. It also includes a component called KatePart, which runs inside numerous other KDE applications, including Quanta+ (on KDE 3 only), KWrite, Konqueror, and Kdevelop. Kate provides syntax highlighting for over 120 text formats, making it perfect for whatever programming language you choose.

Many KDE 3 users swear by the K menu and would dare anyone to challenge it with something better. Fortunately for those people, KDE 4 retained that menu version as an option. For the rest of us, there are a couple of more robust menus that offer a variety of features. Lancelot is a third-party menu that has now entered into the KDE fold. It is the one I use, and many others have found it pretty useful. In this post, I will present to you some of Lancelot’s features so that you can decide if it is right for you.

For those who always feel that gaming is not suitable in Linux OS and it is always an hassle to install and get games to run in Linux platform, then DJL will definitely change the way you think.

Djl is an open-source (GPL licensed) game manager written in Python 2.5 for the GNU/Linux Operating Systems. In short, it is an application that allows you to install/uninstall/manage your games easily. With Djl, you can browse through its repository of 100+ games and install the game you want with a simple click. No longer do you need to worry about game dependencies and all the command lines.

There are plenty of things that I love about Linux, but when it comes to maximizing battery life performance, there is very little to desire. On the frontend, you might be running very few applications, but unknown to you, there are actually plenty of applications running in the backend that are quietly draining away your battery. Compiz, workspace, dock are few such examples. As a result, a battery that used to last 3 hours can only last for 2 hours (or less) now.

So what can you do about it?

PowerTOP is an application that allows you to view information about programs that are misbehaving while your computer is idle. With this information, you can then make changes and optimize your computer to squeeze more juice out of your laptop battery.

For those who own an iPhone/iPod Touch and at the same time is an Ubuntu (or Linux) users, here’s is a good news. You can now easily mount your iPhone in your Ubuntu without having to jailbreak your phone.

In the past, the dirty but effective way to access the iPhone from your Linux system is via SSH. This requires you to jailbreak your phone and it voids the warranty. With iFuse, you can now mount your iPhone/iPod Touch under Linux with just a USB cable. You can also view/edit/cut/copy/paste the file just like any USB disk drive.

Perhaps Mac users know this better than anyone else.  Shortcut keys do exactly what they say, give you shortcuts, saving you time. On my previous computer, my “C” key had worn off the keyboard because I spent so much time copying with “Ctrl-C” rather than going to the menu each time to select “copy”. Whether you are starting an application or cycling through virtual desktops, Linux users tend to love shortcut keys just as much.

In KDE, shortcut keys are customizable for each and every application, and you can also customize global shortcuts that affect the desktop, window manager, command interface, and other features. What follows is a brief guide to using KDE shortcuts, but first I am going to press “Ctrl-S” to save my work.

As time goes on, netbooks are getting more and more popular. These small, cheap, portable computers are gaining popularity in situations where you want the flexibility of a laptop, but don’t need the raw power or price tag of a high-end machine. Some come with Windows, some come with Linux. Unfortunately, the pre-installed Linux on some netbooks can be lacking in quality and features. For those who aren’t satisfied with the default OS on their netbook, Ubuntu has created Ubuntu Netbook Remix.

As the name implies, it’s Ubuntu with some tweaks to make the size and speed of the OS more appropriate to the hardware you’ll find in your average netbook. The most noticable difference is that they’ve completely re-skinned the standard Gnome desktop into something more closely resembling Gnome Shell than the Gnome you’re used to.

For those who are sick of using Windows XP on their netbook and wanted to try out a netbook-efficient and more user friendly OS, then Jolicloud could well be the one heading to your netbook.

Jolicloud is a new Linux distro based on the Ubuntu Netbook Remix, but specifically optimized for netbook devices. What make it stands out from the rest is its Web services that delivers a whole new Web-centric experience to its users (we will discuss more on that later).

Jolicloud is currently at closed alpha testing stage and only offer download on an invitation basis. The download is a LiveCD installer of around 600MB, distributed in iso format. You will have to use a USB creator software to mount the iso file on a USB drive before you can use it to install on a netbook.

Digikam is a free and open source photo management software package for KDE. Many KDE-based Linux distributions either come with Digikam installed or have it available in their repositories. With Digikam, you can import photos from your digital camera or flash memory, organize and tag them, rate them, edit them, and export them to various services or custom galleries.

Three popular services that Digikam can handle are Flickr, PicasaWeb, and Facebook. The first two are social photo sites, and the last is a social networking site. All three support photo plugins used by Digikam. This makes uploading photos quick, easy, and painless.

I am operating under the assumption that you already have accounts on the services you want to use. If not, you will need to register and activate whichever accounts you want before you proceed.

Many people don’t think of their command prompt as a particularly useful thing, or even pay it much attention. To me, this is a bit of a shame, as a useful prompt can change the way you use the command line. Well I’ve scoured the Interwebs looking for the best, most useful, or sometimes most amusing bash prompts. Here, in no particular order, are the ones I’d be most likely to use on my computers.

Note – to use any of these prompts, you can copy & paste the “PS1=” line directly into your terminal. To make the change permanent, paste the line to the end of your ~/.bashrc file.
