In a surprising development that seems really strange and unnecessary, Firefox 2.0 won’t go to the previous page when I press the “backspace” button on the keyboard. I have grown used to this over the period I have used Firefox. The fact that I can’t use backspace the way I am used to has been annoying me no end. So I decided to dig a little deeper.

The feature was removed to fix a bug. But then, until the bug fix propagates to a firefox build available on Ubuntu, one has to resort to a little scratching to fix the matter. Here’s how you resurrect the backspace button in Firefox 2.0.

Automatix is a graphical interface for automating the installation of the most commonly requested applications in Debian based Linux operating systems.

Installing Popular Applications On Your Ubuntu Desktop With Automatix2

This tutorial was written while offline and without any kind of browser open. That’s right. You can blog right from your gnome-based desktop with the greatest of ease!

Tutorial for the day: Installing and blogging with Drivel.

To install Drivel you can use the basic methods we’re familiar with. Via the command line or from “Applications” > “Add / Remove” > search:Drivel. (command line “sudo aptitude install drivel”

You can then access Drivel from your Applications menu inside the Internet section.

Some times you want to use iSO images without burning them.If you don’t want to waste your CD’s/DVD’s here is the simple possible solutions using these tips you can mount and unmount ISO images without burning them.

I know two possible solutions

Now we will see each one in detailed

Mount and Unmout ISO images without burning them

There are times when people make mistakes, and manage to do crazy things to working systems. It wasn't so long ago that a hasty deletion caused me all kinds of problems. Recently I read of an unfortunate sysadmin who managed to recursively change permissions on their root filesystem - and here is my attempted solution.

The problematic command was:

(none):~# chmod -R 777 /

Still in this case, I had to install several times an older version of ImageMagick. Why? Not for the application itself, but because of some applications that relied on the php wrapper (the imagick pecl module). This compiles fine with ImageMagick 6, but many functions fail. So in order to have the php module working properly I had to first install imagemagick 5 that is the last version the php module works fine.

I will show how to install ImageMagick 5.5.7 (the latest version available from the 5 branch) from sources on a Debian Etch system. Debian obviously contains packages for ImageMagick (v. 6.2.4 at the time of writing this post), that can be installed as easy as

Install ImageMagick 5.5.7 on Debian

You've spent hours installing, configuring, and tweaking your system into perfection. Every device is working properly, every patch applied, every last last application is up to date, and your system is contently purring like a lion with a belly full of wildebeest. This is a prime time to save an image of your system in case anything screws it up. There are many commercial solutions available, but what free utilities will properly back up your system?

Backing up your system with free software

  • Spark on Kubernetes at Spark Summit EU
    I’ll be speaking about Spark on Kubernetes at Spark Summit EU this week. The main thesis of my talk is that the old way of running Spark in a dedicated cluster that is shared between applications makes sense when analytics is a separate workload. However, analytics is no longer a separate workload — instead, analytics is now an essential part of long-running data-driven applications. This realization motivated my team to switch from a shared Spark cluster to multiple logical clusters that are co-scheduled with the applications that depend on them.
