Do you still deny the power of OpenSource?

January 22, 2010

Have you watched the movie Avatar? Or the movie District9? Let me tell you something which you might not know about the movies. Those movies and many other were rendered on a Ubuntu based server farm (specs and references later). If you are a hardcore Linux hater then I recommend not watching the movies, hehe! Don’t take it seriously go and watch the movies if you still haven’t because those movies might have not been possible without OpenSource and Linux.

From the Dustin’s blog post:

I just attended Paul Gunn‘s talk at LCA2010, entitled:

  • Challenges in Data Centre Growth (or, “You need how many processors to finish the movie???”)

Paul is a Systems Administrator at Weta Digital, a Wellywood digital effects studio here in Wellington, New Zealand. Check out some of the feature films that Weta Digital has worked on, and I think you’ll recognize a few. District9, Day the Earth Stood Still, Jumper, King Kong, Lord of the Rings, Fantastic Four, Eragon, X-Men, i-Robot. Wow!

Now you know what few other movies were also rendered using that Ubuntu server farm. Now lets get back to the specs of the server farm so you know what Linux is capable of. Weta Digital have 2Petabytes of diskarray, 10gbps of networking and 35,000 cores (4,000+ HP blades). Now you might be thinking that those movies might have taken couple of hours to be rendered on such huge setup? No those movies still took around 48 hours to be rendered on that setup. Did you see the benefits of using open source here? Not yet?

  • No Licensing cost for the OS
  • Free Support
  • No hardware requirements from vendor
  • Ability to modify the kernel as per the setup (if needed)

The above benefits are just few of the many that I could think of. There may be many more in the long run but you have got the idea! didn’t you? With proprietary software Licensing cost alone would have been more then the cost of setting up small OpenSource Lab. Then the additional support cost plus no ability to modify the kernel (if needed) to run efficiently in such a huge environment. And we all know how proprietary Operating system vendors provides you list of the hardware requirements when you tell them how big environment you are will to create.

Do you have any such OpenSource success stories? Or may be about Linux? Let us know.

OpenSource and me in 2009

January 9, 2009

First of all I am sorry for not being able to post on the blog, as I was really taken over in the past. But once again, now I will try to keep the blog updated else there is no point having the domain and blog here on wordpress.com, so I will now try to be regular.

I also have to write an article regarding Pakistan’s Economy and OpenSource, which is still not completed and already have been behind the scheduled. But I hope I will get it done very very soon. Hopefully sometime next week, although I will not be able to post it here until I get permission from Rabia, but lets see what happens.

As far as Opensource is concerned there are many things that has been changed, Ubuntu 8.10 came our, OpenSuse 11.1 came out, I had the chance to install OpenSer, etc etc. But couldn’t wrote about them here on the blog. I will try to update all of it here so I can later reference it, and also I feel very happy when someone find the posts here useful for them.

So, its like resolution for this year, that I will keep the blog updated.

How to fix suspend/hibernate stop working after new linux install

July 19, 2008

This is for those who had suspend/hibernate working fine, and then suddenly it stopped working. So you must be wondering what is broken? Or what have you done wrong to your system. This is because you either have installed another copy of Ubuntu or someother linux on separate partition and that changed the UUID of swap partition. So now you need to tell your Ubuntu system about that new UUID.

Below are the steps to solve the above mentioned problem. (more…)

Are you wondering why PSI on ubuntu is not playing any sounds?

July 19, 2008

So you are using PSI on Ubuntu and wondering why PSI is not playing sounds on new messages and on other events. PSI uses a play command to play sounds. You need to install few sound libraries that are used by play to enable PSI to play sounds. Use the following command to install required libraries.

sudo apt-get install sox libsox-fmt-all

Hope this will be helpful.

June 28, 2008

Yay!!! one more yay for Firefox 3 and Firebug team. Firebug is now finally available for Firefox 3, specially for Ubuntu users its a breeze. Just do:

sudo apt-get install firebug

If you are not using Ubuntu, Get your firebug from Mozilla.

So there is alot happening for Firefox 3, As I already posted how efficient it is for memory and other resources. Also the bookmark management is awesome. Have a look at my firefox 3 post.

Kudos to Joe Hewitt for giving us something like Firebug.

Firefox!!!

June 18, 2008

firefoxYay! Finally the long waiting firefox 3 is out. I have been using the beta and rc versions for some time as I was using Ubuntu 8.04 (Hardy). But Firefox 3 stable is out now and is available for download. Its time for celebration for all Firefox users, because Firefox 3 is really a nice improvement since Firefox 2.

Firefox 3 is much faster, memory efficient, and my loving bookmarks management wow!. There is whole lot of things I might have missed but these 3 things were really what I wanted in firefox. And now it just rocks, its out of the world.

This is not just another firefox fan praising him, but if you don’t believe me then go and try it, grab your copye of firefox now.

Happy browsing everyone!

Missing Google Gears on its first birthday

May 29, 2008

Happy Birthday Google Gear, oh I forgot its only “Gears” now. Long Live Gears, but unfortunately I have been missing you alot. ou have been quite useful for me all this time, but unfortunately I love Firefox more then anything else and being on Firefox 3, I don’t have you anymore.

Hopefully this will fixed soon and I will be able to have you back in my FireFox. I am a happy user of Ubuntu 8.04 (Hardy) which comes with FireFox 3, which is just so awesome that I can’t go back to FireFox 2 and for this I had to sacrifice. My most of Google extensions don’t work anymore in Firefox 3 which includes Google Gears too.

I still want to have all those extensions back, but not sure how much time will it take, I have also read that FireFox 3 is going to be released in June, they have already released rc2 of FireFox 3. So stay tuned every one, FireFox 3 stable is coming soon.

Hibernate and suspend works perfectly fine on ubuntu 8.04

April 30, 2008

Wowwwwwwwwww! yes this was what I shouted when I installed Ubuntu 8.04 Hardy and enabled restricted drivers for my ATI card and found that Hibernate and suspend just works out of the box. Brilliant. I don’t remember where but I read somewhere that even sky is not the limit for Ubuntu and Mark Shuttleworth. This is so true, so true that it is just difficult for me to express.

The only thing that I didn’t liked is Firefox 3 bet 5 is forced on you, even though Firefox-2 is available in repository but making Firefox 3 beta verson a default choice is not the good decision. Because my beloved Google browser sync does not work with Firefox 3 and neither many of other available extensions.

I have tried both Ubuntu and Kubuntu flavors of Hardy and both are impressive. I will keep posting updates and my experiences with Ubuntu from time to time. For now, I have to leave we will do it later.

Ubuntu 7.10: Hibernate or Suspend does not work with restricted ATI drivers.

October 28, 2007

Due to a bug in restricted ATI drivers Hibernate or Suspend does not work on Ubuntu 7.10. When I tried to Hibernate/Suspend I got a blank screen which waited for nothing for ever. So I put a little search on the issue and found that this is the problem with ATI restricted drivers. Currently there are only 2 solutions for the problem:

  1. Use OpenSource ATI drivers.
  2. Stay with Ubuntu Fiesty, which is absolutely not a good option for many of us.

Note: I haven’t tested any of the above solutions. But this is what I found while doing the search for the solution of this problem.

I am not going to use OpenSource ATI drivers, because I don’t really need Hibernate/Suspend currently. When I will be needing them I will surely go for the OpenSource drivers. But maybe by that time we will have a fix/patch for the solution available.

Ubuntu Compiz Fusion on ATI

October 23, 2007

I tried Ubuntu on Acer Ferrari, it worked like charm. But when I tried to enable compiz fusion or so called desktop effects it wasn’t that straight. I would say it was a problem because every howto I found about enabling compiz fusion or desktop effects was missing the very basic requirement for desktop effect. That is xserver-xgl package, this package needs to be installed before you can enable desktop effects on your Ubuntu desktop. Use the command below to enable xgl on your Ubuntu.

Note: From Ubuntu 7.10 you only have to install the package, the xgl server will be automatically enabled.

apt-get install xserver-xgl

There wasn’t any other problem, the fglrx drivers from ubuntu repository worked fine for me. I have ATI Mobility Radeon X1600 256MB that cam with my laptop. Need to check the rest of features, like camera, bluetooth mouse and connectivity my Nokia E50. I think enough for now.
