Are you a Fedora user who wants to check out the new Australis Theme for Firefox scheduled for release with Firefox 28? However, you are a bit apprehensive of letting go that stable release of Firefox in bundled within your Fedora installation by default, just in case something goes wrong with the nightly beta release.

If this is what defines your current dilemma, fear not. You can have both the stable as well as the nightly beta versions installed simultaneously in your computer in a few simple steps without any trouble at all! Here’s how to do it in case of Firefox Nightly version 28 [the latest release at the time of writing this post]:-

Step 1: Login as Super User:-

$su

Step 2: Get the nightly package:-

Go to http://nightly.mozilla.org to get the latest available nightly build for your system.

Alternatively, you can use the command line tool wget to directly download it via the command line as follows:-

#wget http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-trunk/firefox-28.0a1.en-US.linux-x86_64.tar.bz2

Step 3: Extract the contents of the tar ball as follows:-

#tar -xvf firefox-28.0a1.en-US.linux-x86_64.tar.bz2

Step 4: Rename the extracted directory to “nightly”:-

#mv firefox nightly

Step 4: Create an installation directory:-

#mkdir /opt/firefox

Step 5: Move the contents of the “nightly” directory to the installation directory:-

#mv /nightly /opt/firefox/nightly

Step 6: Create a Symbolic link for the Nightly installation:-

#ln -s /opt/firefox/nightly/firefox /usr/local/bin/nightly

Step 7:Run Firefox Nightly by typing the following within the command line or the alt+f2 launcher:-

For command line: $nightly

For alt+f2: nightly

Step 8: Relax and enjoy the Australis awesomeness! 🙂

Installing Microsoft TrueType Fonts in Fedora18 / 19 / 20


This is something that I just learned how to do, courtesy of a documentation work that I need to for my college’s fourth semester evaluations, where the requirements state that I need to use Arial / Verdana fonts for my Project Report. The interesting part is that I’m a hardcore Fedora user who uses LibreOffice for all my documentation purposes and as obvious as it may sound, these fonts don’t come pre-installed in Fedora 18. Du-uh? Right? So, I had to distinctly install these fonts on my laptop. How did I do it? Here’s the breakdown.

First here’s a bit of a trivia for those who already don’t know this! (Read: Yack):

Microsoft TrueType fonts (TTFs) are quite commonly found throughout the web, usually specified in stylesheets. However, for Linux users, the most common of these TTFs don’t come pre-installed in most of the common distributions by default. Instead, they are replaced by generic equivalents, usually fallback fonts most commonly defined in stylesheets (again!). This is also true even case of offline documents such as spreadsheets, presentations, or plain .doc files.

Installing TrueType font packages allow you to see content created using these fonts just as the content creator originally intended.

The Microsoft TrueType fonts package includes the following font-families:

  • Andale Mono
  • Arial Black/Arial (Bold, Italic, Bold Italic)
  • Comic Sans MS (Bold)
  • Courier New (Bold, Italic, Bold Italic)
  • Georgia (Bold, Italic, Bold Italic)
  • Impact
  • Times New Roman (Bold, Italic, Bold Italic)
  • Trebuchet (Bold, Italic, Bold Italic)
  • Verdana (Bold, Italic, Bold Italic)
  • Webdings

And here’s the part on how to install these fonts! (Read: Hack):

You can install the MS core fonts by installing the msttcorefonts package. Here’s how to do it. The gist describes what to do, and the commands explain how to do using the Terminal. You may need superuser privileges or sudo configured. :-

  1. Make sure you have the following rpm-packages installed. Any version should do.
    • rpm-build,
    • wget,
    • A package that provides the ttmkfdir utility. For Fedora Core, ttmkfdir should suffice.
  2. Download the latest msttcorefonts spec file from here.
  3. Install the cabextract utility.
    • sudo yum install rpm-build cabextract ttmkfdir
  4. Build the msttcorefonts-2.5-1.noarch.rpm package.
    • $ sudo rpmbuild -bb msttcorefonts-2.5-1.spec
  5. Install the fonts:
    • $ sudo yum install /root/rpmbuild/RPMS/noarch/msttcorefonts-2.5-1.noarch.rpm

Programming on Mobile Devices


This is a thought that’s been rather bugging me for sometime now:

Is writing code (programming) via mobile devices really not a very feasible idea?

In the current scenario, almost all conventional programming is done on desktop computers (PCs, laptops and the likes), wherein we have a standard keyboard which is used to write down all the code, and a relatively large enough display device to help us visualize what we are writing. However, with the mercurial rise in popularity of mobile devices we have seen a huge shift from conventionally used devices to mobile devices with almost all major aspects of modern day computing making a gradual yet steady shift towards mobile computing.

We see a lot of developers now focusing on “Programming for mobile devices“, however there is an evident lack of focus on “Programming on mobile devices“, which is actually quite weird in my honest opinion. On one hand we are talking about a truly mobile world, where almost every aspect of computing is being made available for on the go mobile devices. Whereas, on the other hand, for the very basic necessities for enabling these mobile functionalities we fallback to traditional computers (and by traditional, I do take into account laptops as well, because no matter how small in size they may be, they still follow the same desktop oriented norms).

Why is it so that we aren’t yet completely comfortable with the thought of being able to write a piece of code on our mobile handsets? I know some people may argue that it is possible to write code in some ABC language using a XYZ software on a tablet device. However, what I ask is that are you really comfortable with the current scenario? Why can’t we find a nice alternative way to make programming on devices such as mobile handsets more intuitive, organic, comfortable and developer friendly?

The main problem with devices as small as mobile handsets as I see it, is a combination of low resolution / small screen size + lack of a comfortable keyboard / input device. But is it really the main challenge that we are talking abut here? Or is our mindset the main challenge? Is it really that difficult to take on the challenge of redesigning the existing programming methodology and create an efficient solution for mobiles, or is it just that we are just too lazy and or narrow minded to explore the possibilities of programming on mobile devices.

I have heard the proverb which says “Nothing is impossible“, however, I think there’s an even more dangerous public opinion which states “This is not feasible!” which generally results in the eventual death of ideas. But is feasibility really applicable here or should it be the willingness and openness in one’s mind to imagine and realize the things which others might reject as non-feasible and bring about a much needed change in the paradigms? What do you think? Please do leave your thoughts on this as comments below.

Running Friendlycode – A local instance of Thimble


Here is a breakdown of how to run Friendlycode in 3 (maybe not-so-simple) steps.

Friendlycode Snapshot

Friendlycode – An Offline Thimble Instance.

Prerequisite: A static file server such as Apache.

Steps:-

  1. Download Friendlycode from here.
  2. Extract the contents of the friendlycode-gh-pages package into a directory named friendlycode within your file server’s document root. For example, in Apache you might want to put the friendlycode directory inside www/html or www or public_html based upon your Operating System’s preferences.
  3. You can then run a trivial embedding of Friendlycode from your browser by navigating to the examples/bare.html file within the friendlycode directory.

    Example: http://localhost/friendlycode/examples/bare.html

Additional features in Friendlycode:-

  1. Javascript: By default, Friendlycode doesn’t allow JS. An example of an embedding that allows JS and publishes using an alternate API can be run from the examples/alternate-publisher.html file.

    Example: http://localhost/friendlycode/examples/alternate-publisher.html

  2. Localization: Friendlycode currently uses Transifex for localization. To localize Friendlycode in your language, please visit the Transifex friendlycode project. Any strings you don’t translate will fall-back to English. To try out a localized version run the examples/transifex.html file.

    Example: http://localhost/friendlycode/examples/transifex.html

  3. Development: If you are a code ninja and want to play around with the dev-repository of Friendlycode, you can checkout the excellent Readme.md file at Atul’s friendlycode repository at Github.

Installing Steam for Linux Beta | Counter Strike for Fedora 17 / 18 / 19 / 20


Here’s the link to a really interesting article by Russel Bryant that I found on the web. Especially helpful for all my geeky gamer friends who keep on complaining about how they are not able to play Counter Strike or Team Fortress 2 on their Linux based systems. Enjoy!

If however you are a counter strike freak and this link doesn’t completely satiate your needs, you may try referring to this blog for Chris Daniel’s take on installing Counter Strike on Fedora 18.

Debugging NO KEY warning during “yum install vlc”


This is a problem that I encountered today while tryiing to install VLC media player on my brand new Fedora 18 installation.

Right after the dependency resolutions are complete, yum returns the following warning:-

Transaction Summary
===============================================
Install 1 Package (+45 Dependent packages)

Total size: 37 M
Installed size: 118 M
Is this ok [y/N]: y

GPG key retrieval failed: [Errno 14] Could not open/read file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmfusion-free-fedora-18-i386

Did a bit of snooping around over the internet and found the missing rpmfusion keys at: http://rpmfusion.org/keys and derived the following solution:-

Step by step solution to the problem [root login used]:-

  • I have already compiled the key into a single .gz file, which can be downloaded from this link: http://goo.gl/bKoyb
  • Place the .gz file in the directory: /etc/pki/rpm-gpg/
  • #cd /etc/pki/rpm-gpg/
  • #tar -xvzf RPM-GPG-KEY-rpmfusion.tar.gz
  • rm RPM-GPG-KEY-rpmfusion.tar.gz
  • #yum install vlc
  • You should get this output after dependency resolution is complete:

  • Enter ‘y’ (without the quotes!)

Voila! VLC’s installed!

NOTE:It is highly recommended to do a ‘yum update’ after the installation procedure is complete, as it helps ensuring that the new rpm keys are standards-compliant!
