Netflix, the popular video-streaming service that takes up a third of all internet traffic during peak traffic hours isn’t just the single largest internet traffic service. Netflix, without doubt, is also the largest pure cloud service.

Netflix, with more than a billion video delivery instances per month, is the largest cloud application in the world.

At the Linux Foundation’s Linux Collaboration Summit in San Francisco, California, Adrian Cockcroft, director of architecture for Netflix’s cloud systems team, after first thanking everyone “for building the internet so we can fill it with movies”, said that Netflix’s Linux, FreeBSD, and open-source based services are “cloud native”.

By this, Cockcroft meant that even with more than a billion video instances delivered every month over the internet, “there is no datacenter behind Netflix”. Instead, Netflix, which has been using Amazon Web Services since 2009 for some of its services, moved its entire technology infrastructure to AWS in November 2012.

Google unveiled a “patent pledge” that it hopes will shield cloud software and big data developers from the type of litigation that has engulfed the mobile phone industry. The pledge, which is like a non-aggression pact, covers ten patents related to Google’s MapReduce technology.

The pledge, which Google announced on Thursday, says that developers are free to use or sell the technology described in the patents without fear of future lawsuits. The shield applies, however, only to projects based on open source software that is available to all

The ten patents included in Google’s pledge include a controversial one issued last year that covers a form of parallel processing known as MapReduce. The patent gave rise to fears that Google would be able to monopolize tools like Hadoop, which is an integral part of the so-called “big data” revolution that is fueling a wide range of new products and services. Google’s pledge appears intended to allay that fear.

Berlin filmmaker Sam Muirhead is attempting to live a completely open source life for one year. Here’s why.

The phrase ‘Open Source’, to many people, means ‘software you don’t have to pay for’—but really it’s so much more than that. It’s a way of thinking and working focused on transparency and collaborating with others. It’s about sharing ideas, plans, and developments for the benefit of the commons. And it’s definitely not just software.

I’ve been following open source closely over the last few years, but as a filmmaker, I never felt like I had skills to contribute to the movement’s development.

But then I realized that everyone, whether librarian, beekeeper, or mechanic, everyone can use the abilities they have in some way to make the world a little better, to help out a cause or an interest they feel is worthwhile. I felt sure that open source could use a filmmaker.

So I’ve started a somewhat insane plan to spread the word about open source, to get others thinking and talking about these ideas of collaboration, transparency, and modification—to show how far open source has come and how far it could go. This will be my Year of Open Source.

For one year I am trying to go as open source as possible, in all aspects of my life—the shoes I wear, the phone I use, even how I get around. I’m not buying any proprietary or traditionally copyrighted products unless all other options are exhausted. I’m looking for and switching to more open, transparent products which are replicable by others, trying to highlight the benefits of treating others as collaborators rather than competitors. I’ll be investigating how the open source philosophy might apply to different areas of life, where it fits well, and where it might not work. Is anybody working on an open source microwave? What would open insurance be like?

Since my first steps into QML when the Ubuntu SDK was launched, I have become a bit addicted to it. I decided to try to write a QML declarative game, and I settle on a shooting fighter jet game. Finally had enough content to put out an alpha. Here is the video:


The code for it in on my LP Junk branches, not really ready for review yet ;) but happy to have help!

You might notice that I am using the keyboard to drive the game in my computer, I have also build a touch joystick that so far works ok in the Nexus 7, but needs some calibration.

PS: if you have some problems with playing the video, try jumping a head 10 secs, it also helps if you play it in HD :)

Today we announced a collaborative support and engineering agreement with Dell.  As part of this agreement Canonical will add Dell 11G & 12G PowerEdge models to the Ubuntu Server 12.04 LTS Certification List and Dell will add Ubuntu Server to its Linux OS Support Matrix.

In May 2012, Dell launched the OpenStack Cloud Reference Architecture using Ubuntu 12.04 LTS on select PowerEdge-C series servers. Today’s announcement expands upon that offering by combining the benefits of Ubuntu Server Certification, Ubuntu Advantage enterprise support, and Dell Hardware ProSupport across the PowerEdge line.

Dell customers can now deploy with confidence when purchasing Dell PowerEdge servers with Dell Hardware ProSupport and Ubuntu Advantage.  When these customers call into Dell, their service tag numbers will be entitled with ProSupport and Ubuntu Advantage, which will create a seamless support experience via the collaborative Dell and Canonical support and engineering relationship.

In preparation for this announcement, Canonical engineers worked with Dell to enable and validate Ubuntu Server running on Dell PowerEdge Servers.  This work resulted in improved Ubuntu Server on Dell PowerEdge support for PCIe SSD (solid state drives), 4K-block drives, EFI booting, Web Services Management, consistent network device naming, and PERC (PowerEdge RAID Controllers).

Dell hardware systems management can be done out-of-band via ipmi, iDRAC, and the Lifecycle Controller.  Dell OMSA Ubuntu packages are also available but it is recommended to use the supported out-of-band systems management tools.  Dell TechCenter is a good resource for additional technical information about running Ubuntu Server on Dell PowerEdge servers.

If you are interested in purchasing Ubuntu Advantage for your Dell PowerEdge servers, please contact the Dell Solutions team at Canonical.  If your business is already using or thinking about using a supported Ubuntu Server infrastructure in your data-center then be sure to fill out the annual Ubuntu Server and Cloud Survey to provide additional feedback.

A few months back, I decided to write a Simple ToDo app for Android, then I hooked it up to a cloud backend, using Juju. That was my first Android application, so I got to experience first hand the latest developer documentation and development environment.

Last month, Canonical launched Ubuntu for Phones, that gave me the idea to re-write the same application on QML using the Ubuntu Components.

Clearly comparing a new SDK-Alpha with a stable platform like Android will seem hardly fair, however, keep reading as you might be surprised of the results.

QML vs Dalvik Java

Lets start with QT/QML vs Dalvik/Java – I found QML really easy to get to grips with and be productive. I had the UI (see picture below) running in no time and I would say much faster than with Android.  QML is a very flexible declarative environment that allows you to embedded quick logic into the layout. This is a blessing and  a curse.

While with Android, it was very easy to keep a nice MVC  separation, I struggled to stop the leaks in QML. So while it is very easy to quickly write a functional application, it does not impose what you would consider as good development practices.

In summary, they are both very powerful development environments.

IDE: Eclipse vs QtCreator

Part of the development experience is the IDE. I must say that I simply love the QTCreator. Possibly not as polish as Eclipse but you don’t need to read a manual to use it. Also, with a quick integration with the HUD, it is just very simple to use.

So what is QTCreator missing? A good emulator. The Android Development Kit (ADK) provides a really good user experience to develop mobile solutions. QMLScene gives you similar functionality but does not simulate a phone environment. However, all the technology is there, and  I am sure that will be included in the v1.0 version of the SDK.

Documentation

I can’t fault Android developer documentation, but taking into account its popularity, you  wouldn’t expect anything else.

I was very surprise of the quality of information on http://developer.ubuntu.com/ and specially with the component showcase.

componentshowcase

The only thing to watch out for is that in Android you can get all the info you need from a single website. With QML you quickly end up pinging between Digia, Nokia and Ubuntu pages.

The Code

The code is on my launchpad repos. The actual source functionality is not finished as I am still trying to figure out how to add menu options to access Done items. Anyway, the whole thing is pretty compact compare to the Dalvik code. The actual logic is almost identical in both. A ListView that is populate from an List model. All the data is persisted in SQLite db.

Conclusion

Both environments have been equally painless to work with, the difference is that the Ubuntu environment has *just* been released as an Alpha. I think this is the start of a very vibrant App development ecosystem.

Today’s inauguration of Barack Obama to his second term provides a good opportunity to look back at last year’s campaign and appreciate it in a bit more detail. We’ll skip discussion of the adverts, polls, photo ops, sound bites, political theatre and even the much appreciated informed debate on the issues, and focus instead on the interesting stuff – the IT infrastructure that powers something as dynamic as a presidential campaign. You can imagine the demands placed on such an infrastructure – scalability, reliability, cost effectiveness, manageability, openness, cloud. Once you have those requirements in mind, the clear choice for meeting those demands is Ubuntu. And so it’s no surprise that the Obama campaign reached the same conclusion.  We recently spoke with Harper Reed, the CTO of the Obama campaign, about the challenges he faced and solutions he and his team put in place during the campaign. We’ve published that piece in honour of today’s inauguration; you can find it on our new Insights blog.

The team behind the Samba file, print, and authentication server suite for Microsoft Windows clients announced the release of Samba version 4 yesterday. This version includes significant new capabilities that offer an open source replacement for many enterprise infrastructure roles currently delivered exclusively by Microsoft software, including acting as a domain controller, providing SMB2.1 protocol support, delivering clustering, and offering a virtual filesystem (VFS) interface. It comes with Coverity security certification and easy upgrade scripts. The release notes include details of all changes.

Notably, this includes the first open source implementation of Microsoft’s Active Directory protocols; Samba previously only offered Windows NT domain controller functions. According to the press release, “Samba 4.0 provides everything needed to serve as an Active Directory Compatible Domain Controller for all versions of Microsoft Windows clients currently supported by Microsoft, including the recently released Windows 8.”

Samba 4 can join existing Active Directory domains and provides all necessary function to host a domain that can be joined by Microsoft Active Directory servers. It provides all the services needed by Microsoft Exchange, as well as opening up the possibility of fully open source alternatives to Exchange such as the OpenChange project.

You have critical decisions ahead as you take your first steps into cloud computing.

One of them will be whether to build a private cloud infrastructure in your own data centre, make use of one of the public cloud services offered by vendors like Amazon, Rackspace and HP, or combine the two in a ‘hybrid cloud’ approach.

You can get closer to the right decision by considering the right questions now:

  • Budget - How much do you have (or how much don’t you have) to support your cloud strategy?
  • Speed - When do you need this done? Tomorrow, next year, yesterday…
  • Demand - How many users will you need to support? And will they call come at once?
  • Resources - What kind of resources do you have in-house? And how many can you realistically get your hands on?
  • Privacy -How sensitive is your data? Where are you doing business?

This short, sharp checklist takes you through the process that points you in the right direction and ensures your investments pay off from the start. Download it today.

Apple — one of the most closed companies in the world — is actually using lot of open source and software. Licensing information in the Apple iPhone proves this. Go to the legal section on the iPhone and it cites Linux Kernel developer Ted Ts’o for his code. Linux Suse is there, too.

Zemlin made the point that Apple has hundreds of billions of dollars in cash, which is enough to buy HP, Intel and Dell combined. Instead, Apple purchased the copyright to the Common Unix Printing System (CUPS), which now is on every Linux and Apple system.

The list of companies using Linux does not stop at Apple. Microsoft, which once equated open source with communism, is now a top contributor to the Linux Kernel project. And VMware is getting on the bandwagon.
