Edit: There's no need to compile Docky from source on F14 any more. The packages have landed on the official repos. If you still want to build from source, you are welcome to use this post. For everyone else, just fire a terminal and type: $ su -c "yum install docky" If you already had installed it from source, see the Step 0 below to uninstall it. About five months ago I posted a blogpost named " Howto Install Docky on Fedora ". Little did I know that people will be using my guide as much as they have being doing. A few things have changed since the original post which assumed that the Fedora version running is 13 (please see the comments on the original post) and also Fedora 14 has come out. Therefore, I though of writing a wee bit more up-to-date post eventhough any of this isn't anything remotely serious. This is just to avoid answering question on the original post, as much as for the sake of everyone. Also the official install guide from Docky wik...

If you know me personally, then you know that I'm a big fan of GNOME Do . As a keyboard savvy person I use Do extensively. Do is an application launcher similar to the Mac app Quicksilver. However the GNOME Do team has been putting a lot of research and development into it from the initiation. Result: probably the best application launcher out there for any platform. Some months ago, Do included an interesting theme called Docky which made the launcher acts as a dock (a la Mac, Avant, Cairo Dock, etc.). With the integration of GNOME Do, there's no need to say that Docky was super cool. And it started gaining features in a high speed. Ultimately Docky was getting so developed that it became a separate project. Installing GNOME Do on a Fedora system is as easy as: $ sudo yum install gnome-do There are some packages with the names starting from gnome-do-plugins*. With the addition of these GNOME Do can truly enhance your desktop experience. Give it a fair try, I'm pretty...

Pagers If you use a Linux/Unix system using a pager should be quite familiar to you. A pager in the Unix sense is a program which lets you view pages of contents. Examples for pagers are the Unix commands " less " and " more ". It's likely that your man page viewer is also using one of these. The program less is perhaps the most popular of these, with more features than " more ". These pagers are nice to use use and come very handy in day to day Linux/Unix operations. When you just need to view a file (instead of opening it for editing) it's quite natural to use less. If it's a file with a few lines we'd usually use cat , but less is more convenient on longer files. One irritating thing about less is, there is no syntax highlighting support there by default. You can try to use an external program like " highlight " for the highlighting part and then pipe it to less . (Eg: $ highlight --ansi --force my_file | less -R ) But ...

Setting up a Subversion (svn) repository is something development teams have to do fairly regularly, not that I want to use Subversion. :) If you listen to me, go use Git . Subversion is undoubtedly very good. But after using Git for about a year, you can't simply get me to switch back. Git is that good. :) I've written about Git before . In cases where you can't use Git (or you feel too castrated by TortoiseSVN, pardon me for the pun) you can use Subversion. In this post I'll go through the steps you have to follow to get a basic Subversion setup up and running on a CentOS 5 Linux host. However I think you should be able to use this on other Linux distros too. There's more than one way to host a Subversion repo. I'm going to stick with one way involving WebDAV. Don't mind the buzz word. It's the most common usage for this purpose. If you want a repository where you want to checkout and commit remotely, this is an easy way of getting it done. In addition...

Again, I'm not switching to Java. :) For clarity, I'm helping one of my online buddies to setup and use Ruby even as I write this. This work was something I had to do for a Rails project which used JSPs and stuff with a MySQL database over JDBC. The application setup was quite interesting calling JSPs to work with a Rails webapp. Actually the following things are found on the Internet. I cannot remember all the sources I looked at, but one was the MySQLs own documentation and Apache Tomcat documentations. So if this works (which in my case did), credit should not be mine. :) Here's the setup. GNU/Linux (in my case CentOS 5, although should work with any Linux distro) Apache Tomcat (5.5.25, should work with Tomcat 5.5 range) Sun JDK (1.6.0_04) MySQL (5.0.22) MySQL Connector/J (5.1) 1. I assume that Java is setup ( See my previous post for more details on setting up Java manually), and your MySQL is running on the same host on port 3306. Please replace your actual settings i...

I'm not switching to Java. :) But this particular thing is something I've answered several times. So instead of repeating it every time, I'll put the details here and point others here. Installing Sun's Java (JDK and JRE) manually, without using something like yum, apr-get, urpm, etc. seems to be something many desktop (or whatever) Linux users want. For example they want to run certain applications like NetBeans, FrostWire, etc. which require a JRE to be available. This tutorial is going to take you through the steps you need to setup a working JRE/JDK on a Linux system. You may as well take this idea and tune it for your non-Linux environments like Solaris, *BSD. Note: This howto assumes you have 'sudo' configured for you. If you don't have 'sudo' configured, you'll have to either use 'su' or login as root to use the commands I have provided with 'sudo' at the beginning. Please replace file names and paths in this howto with you...

I know some of you are asking why , rather than how , regarding migration from Mozilla Thunderbird to Evolution. Maybe that's why there are lot of Evolution to Thunderbird migration guides, but not many vice-versa. Fear not, here is a guide, to assist who dare to migrate from Thunderbird to Evolution. The techniques described here are tested with the newer versions of both the software, namely Thunderbird 2.0.0.4 and Evolution 2.10.2. On higher versions also this should work without an issue. I think Mozilla people are doing a wonderful job with both Firefox and Thunderbird . From my point of view Firefox is the best general purpose web browser around. It beats most proprietary browser in speed, stability, security, modularity, etc. (and don't start commenting the so and so browsers are greater or so and so is cool too. I know they may be, Fx is simply my choice. This also applies to any comparisons with Evolution too :) However Fxs' counterpart in e mail business, is not y...
