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.

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

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

What’s the best Linux firewall distro of 2017?

You don’t have to manage a large corporate network to use a dedicated firewall. While your Linux distro will have an impressive firewall – and an equally impressive arsenal of tools to manage it – the advantages don’t extend to the other devices on your network. A typical network has more devices connected to the internet than the total number of computers and laptops in your SOHO. With the onslaught of IoT, it won’t be long before your router doles out IP addresses to your washing machine and microwave as well. The one thing you wouldn’t want in this Jetsonian future is having to rely on your router’s limited firewall capabilities to shield your house – and everyone in it – from the malicious bits and bytes floating about on the internet. A dedicated firewall stands between the internet and internal network, sanitising the traffic flowing into the latter. Setting one up is an involved process both in terms of assembling the hardware and configuring the software. However, there are quite a few distros that help you set up a dedicated firewall with ease, and we’re going to look at the ones that have the best protective open source software and roll them into a convenient and easy to use package.

GNOME and Other Software

  • Nautilus 3.24 – The changes
    Since Nautilus was created, if a user wanted to open a folder where the user didn’t have permissions, for example a system folder where only root has access, it was required to start Nautilus with sudo. However running UI apps under root is strongly discouraged, and to be honest, quite inconvenient. Running any UI app with sudo is actually not even supported in Wayland by design due to the security issues that that conveys.
  • GNOME hackaton in Brno
    Last week, we had a presentation on Google Summer of Code and Outreachy at Brno University of Technology. Around 80 students attended which was a pretty good success considering it was not part of any course. It was a surprise for the uni people as well because the room they booked was only for 60 ppl.
  • Peek Gif Recorder Gets Updated, Now Available from a PPA
    Peek, the nifty animated gif screen capture app for Linux desktops, has been updated. Peek 0.9 reduces the size of temporary files, adds a resolution downsampling option (to help the app use fewer resources when rendering your gif), and introduces fallback support for avconf should ffmpeg be unavailable.
  • Cerebro is an Open Source OS X Spotlight Equivalent for Linux
    Billed as an ‘open-source productivity booster with a brain’, Cerebro is an Electron app able to run across multiple platforms. It’s an extendable, open-source alternative to Spotlight and Alfred on macOS, and Synapse, Kupfer, Ulauncher, GNOME Do, and others on Linux.
  • JBoss Fuse 6.3 integration services for Red Hat OpenShift released
    Red Hat announced the latest update to the Red Hat JBoss Fuse-based integration service on Red Hat OpenShift. With the growth of the Internet of Things (IoT), cloud-based SaaS systems, and new data streams, organizations can face increasing pressure to more quickly deliver innovative new services. Traditional centralized, monolithic ESB-style integration approaches are often ill-suited to support the business in responding to this pressure.

  • Meet the chap open-sourcing US govt code – Paul, an ex-Microsoft anti-piracy engineer [Ed: Used to work for Microsoft and now spreads the GPL ("cancer" according to Microsoft) in the US government]
    The manager of the project, Berg said, really wanted to release MOOSE as open source, but didn't know how to do so. As a result it took 18 months to traverse government bureaucracy and to obtain the necessary permissions. It's now available under the GPL 2.1 license.
