Views is one of the most complex of all Drupal modules and one of the most useful of all Drupal modules. The only downside is that, since it is very complex, not too many people have been able to contribute to the documentation of the module. If you search Google for finding out how to programmatically set a filter in Views2 you probably wouldn't find any help. Here is how you do it.

The dream of every person starting out to build websites is to reach out to as many people as possible. Not very many actually make it to more than a few hundred visitors per month on a regular basis. But with the profusion of social bookmarking sites, there is a chance for some of these low traffic sites to get bursts of very high traffic once in a while, for ex: when they get slashdotted. The question is how to outlive such spikes in traffic, without burning large holes in your pocket

Blogger is one of the most popular free blogging service providers out there. Yet again another free service from the kitty of Google. Blogger is a reasonably user friendly blogging platform except for its theming capabilities. If you don't customize anything you can configure most of the stuff through the blogger admin interface but if you did something then you will have to do everything subsequently as well. A very simple task like showing the comment form below the posts requires you to fiddle with the template xml file, if you are already using a customized template.

We have been running the RequestCD Program for more than a year now. For this program we have been heavily downloading iso's, mostly GNU/Linux distributions. We download either through direct downloads or through bittorrent. Bittorrent downloads are inherently safer because the downloaded iso would be guaranteed error free. However http and ftp downloads results in corrupted downloads once in a while. Traditionally when you end up with a corrupted iso you had to download the iso file again. Not anymore. You can easily repair a corrupted iso using Bittorrent.

Upgrading a working server application is always tricky. This is especially true if the upgrade had changes in configuration files and you had customizations done in your local configuration file. The recent exim4 upgrade to version 4.67-3 had structural changes in the configuration files. The suggested upgrade method is to accept all the modifications provided by the upgrade and redo the customizations. But what if you did not read the instructions properly and ended having an exim4 installation that throws out errors every time you try to start exim4.

Setting up Malayalam on Ubuntu or for that matter any other GNU/Linux distribution like Fedora, Mandriva has been progressively getting easier thanks to the wonderful effort of the free software community going by the name "Swathanthra Malayalam Computing" or SMC in short. Most of the patches and tweaks have gone upstream to the OS trunks and most distros are already Malayalam capable. A few minor tweaks are required to set up reading and writing in Malayalam in the latest version of Ubuntu 8.10 - Intrepid Ibex

We had a query from one of our customers to help them migrate their local mail server to Google Apps. They wanted to do this because they did not have the sufficient in-house capability nor have the funds to get paid external capability to support an internal mail server. One hurdle that they were facing was that they had around 40GB of mail left on the local mail server that they wanted to migrate to the new mail accounts they created on Google Apps.

If you have noticed a drastic slowdown in your DSL internet connection after you upgraded to Ubuntu Hardy Heron (Ubuntu 8.04) then it might not be that your ISP is entirely to blame. It could be settings on your PC that is slowing things down. We had a problem in our office where Ubuntu PCs were getting only around 80Kbps as opposed to 2Mbps from Windows machines. After troubleshooting and playing with some configuration parameters we got the Ubuntu Machines up to the same level as the Windows PCs

If you do a google search on this topic you will come across different posts that says how windows does not allow booting of a logical partition and why windows should be installed on a primary partition. The fact of the matter is that windows allows itself to be installed on logical partitions but it will want a primary windows partition to boot up. Recently we faced a situation where we had to make a windows installed on a logical partition boot up on its own.

We had recently been involved in a project to set up a Conference Management System for an International Conference to be conducted in Kerala sometime later this year. We had zeroed in on Pentabarf as the solution we were going to base the system on. Pentabarf is a Ruby on Rails solution that has been used for the last couple of DebConfs. Pentabarf as such is an excellent system, being a system created by programmers for programmers, but it heavily lacked in documentation both on their site and on the world wide web. We however managed to get it installed on Ubuntu with Apache, Ruby on Rails and FastCGI. We are sharing the installation instructions for Pentabarf on Ubuntu here
