  • SQL SERVER – 3 Online SQL Courses at Pluralsight and Free Learning Resources

    - by pinaldave
    Usain Bolt is an inspiration for all. He broke his own record multiple times because he wanted to do better! Read more about him on wikipedia. He is great and indeed fastest man on the planet. Usain Bolt – World’s Fastest Man “Can you teach me SQL Server Performance Tuning?” This is one of the most popular questions which I receive all the time. The answer is YES. I would love to do performance tuning training for anyone, anywhere.  It is my favorite thing to do, and it is my favorite thing to train others in.  If possible, I would love to do training 24 hours a day, 7 days a week, 365 days a year.  To me, it doesn’t feel like a job. Of course, as much as I would love to do performance tuning 24/7/365, obviously I am just one human being and can only be in one place t one time.  It is also very difficult to train more than one person at a time, and it is difficult to train two or more people at a time, especially when the two people are at different levels.  I am also limited by geography.  I live in India, and adjust to my own time zone.  Trying to teach a live course from India to someone whose time zone is 12 or more hours off of mine is very difficult.  If I am trying to teach at 2 am, I am sure I am not at my best! There was only one solution to scale – Online Trainings. I have built 3 different courses on SQL Server Performance Tuning with Pluralsight. Now I have no problem – I am 100% scalable and available 24/7 and 365. You can make me say the same things again and again till you find it right. I am in your mobile, PC as well as on XBOX. This is why I am such a big fan of online courses.  I have recorded many performance tuning classes and you can easily access them online, at your own time.  And don’t think that just because these aren’t live classes you won’t be able to get any feedback from me.  I encourage all my viewers to go ahead and ask me questions by e-mail, Twitter, Facebook, or whatever way you can get a hold of me. Here are details of three of my courses with Pluralsight. I suggest you go over the description of the course. As an author of the course, I have few FREE codes for watching the free courses.

  • Windows Azure: Announcing Support for Windows Server 2012 R2 + Some Nice Price Cuts

    - by ScottGu
    Today we released some great updates to Windows Azure: Virtual Machines: Support for Windows Server 2012 R2 Cloud Services: Support for Windows Server 2012 R2 and .NET 4.5.1 Windows Azure Pack: Use Windows Azure features on-premises using Windows Server 2012 R2 Price Cuts: Up to 22% Price Reduction on Memory-Intensive Instances Below are more details about each of the improvements: Virtual Machines: Support for Windows Server 2012 R2 This morning we announced the release of Windows Server 2012 R2 – which is a fantastic update to Windows Server and includes a ton of great enhancements. This morning we are also excited to announce that the general availability image of Windows Server 2012 RC is now supported on Windows Azure.  Windows Azure is the first cloud provider to offer the final release of Windows Server 2012 R2, and it is incredibly easy to launch your own Windows Server 2012 R2 instance with it. To create a new Windows Server 2012 R2 instance simply choose New->Compute->Virtual Machine within the Windows Azure Management Portal.  You can select the “Windows Server 2012 R2” image and create a new Virtual Machine using the “Quick Create” option: Or alternatively click the “From Gallery” option if you want to customize even more configuration options (endpoints, remote powershell, availability set, etc): Creating and instantiating a new Virtual Machine on Windows Azure is very fast.  In fact, the Windows Server 2012 R2 image now deploys and runs 30% faster than previous versions of Windows Server. Once the VM is deployed you can drill into it to track its health and manage its settings: Clicking the “Connect” button allows you to remote desktop into the VM – at which point you can customize and manage it as a full administrator however you want: If you haven’t tried Windows Server 2012 R2 yet – give it a try with Windows Azure.  There is no easier way to get an instance of it up and running! Cloud Services: Support for using Windows Server 2012 R2 with Web and Worker Roles Today’s Windows Azure release also allows you to now use Windows Server 2012 R2 and .NET 4.5.1 within Web and Worker Roles within Cloud Service based applications.  Enabling this is easy.  You can configure existing existing Cloud Service application to use Windows Server 2012 R2 by updating your Cloud Service Configuration File (.cscfg) to use the new “OS Family 4” setting: Or alternatively you can use the Windows Azure Management Portal to update cloud services that are already deployed on Windows Azure.  Simply choose the configure tab on them and select Windows Server 2012 R2 in the Operating System Family dropdown: The approaches above enable you to immediately take advantage of Windows Server 2012 R2 and .NET 4.5.1 and all the great features they provide. Windows Azure Pack: Use Windows Azure features on Windows Server 2012 R2 Today we also made generally available the Windows Azure Pack, which is a free download that enables you to run Windows Azure Technology within your own datacenter, an on-premises private cloud environment, or with one of our service provider/hosting partners who run Windows Server. Windows Azure Pack enables you to use a management portal that has the exact same UI as the Windows Azure Management Portal, and within which you can create and manage Virtual Machines, Web Sites, and Service Bus – all of which can run on Windows Server and System Center.  The services provided with the Windows Azure Pack are consistent with the services offered within our Windows Azure public cloud offering.  This consistency enables organizations and developers to build applications and solutions that can run in any hosting environment – and which use the same development and management approach.  The end result is an offering with incredible flexibility. You can learn more about Windows Azure Pack and download/deploy it today here. Price Cuts: Up to 22% Reduction on Memory Intensive Instances Today we are also reducing prices by up to 22% on our memory-intensive VM instances (specifically our A5, A6, and A7 instances).  These price reductions apply to both Windows and Linux VM instances, as well as for Cloud Service based applications: These price reductions will take effect in November, and will enable you to run applications that demand larger memory (such as SharePoint, Databases, in-memory analytics, etc) even more cost effectively. Summary Today’s release enables you to start using Windows Server 2012 R2 within Windows Azure immediately, and take advantage of our Cloud OS vision both within our datacenters – and using the Windows Azure Pack within both your existing datacenters and those of our partners. If you don’t already have a Windows Azure account, you can sign-up for a free trial and start using all of the above features today.  Then visit the Windows Azure Developer Center to learn more about how to build apps with it. Hope this helps, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

  • Unity 2d support dropped in 12.10, what now?

    - by tomodachi
    So its been announced. Ubuntu is dropping unity 2d support. I wouldn't mind if it wasn't for two things that are important to me. 1) A working system Unity is nice, i try to use it quite often. But it lags. 2) Support for older hardware. I also have old computers. You can imagine how they would work with unity if my current laptop is slog in Ubuntu. I guess i could use another desktop environment/ window manager , like switching to fluxbox. Anyone have any suggestion ideas/solutions on how to proceed with Ubuntu in the future? All insights welcome

  • Does md2 support skeletal meshes?

    - by jsvcycling
    I'm creating an FPS game. I'm writing my own game engine. So far all the backend stuff is going great. I'd like to support md2 as the native file format for 3D Objects, but I also want to use skeletal meshes. Does anyone know if the md2 file format supports skeletal meshes? In-case you need to know, I'm going to use blender as my Mesh creation tool and C++ as my programming language... Thanks For got to mention, the engine is based on OpenGL... Alright, for anyone who is reading this, I just found the Doom 3 md5 specifications (http://tfc.duke.free.fr/coding/md5-specs-en.html). It gives you some help on writing a parser (see bottom of link), but the example doesn't support lighting and texture mapping (the second set of example code allows for animation). Thanks @Neverender for answering my question...

  • Most efficient arc for developing cross-browser support?

    - by Chris Hasbrouck
    I'm curious to hear what approach people take to planning for cross-browser support when developing a website. There are generally two approaches I've seen developers take in their workflow: -optimize for webkit then apply hacks for IE7-9, or -optimize for IE7-8 then apply newer features for IE9/webkit Basically starting at the front of technology and working toward the back, or starting at the back of technology and working toward the front. How do you do things? What advantages or disadvantage do you perceive in the different way of doing things wrt to developing cross-browser support?

  • How can I get H.264 support?

    - by Chad--24216
    Canonical Limited is shown as a licensee of H.264. I am interested in being able to play H.264 video online when using the Chrome web-browser in Ubuntu (and in the future on Firefox when Firefox supports H.264). Is H.264 support enabled on self-installs of Ubuntu? If not, is there some way I can buy H.264 support for my Ubuntu install? Assume a scenario where I self-installed Ubuntu on a computer that came pre-installed with Windows OS. I'd like to know any and all options available to me for getting H.264 to work on Ubuntu.

  • First languages with generic programming support

    - by oluies
    Which was the first language with generic programming support, and what was the first major staticly typed language (widely used) with generics support. Generics implement the concept of parameterized types to allow for multiple types. The term generic means "pertaining to or appropriate to large groups of classes." I have seen the following mentions of "first": First-order parametric polymorphism is now a standard element of statically typed programming languages. Starting with System F [20,42] and functional programming lan- guages, the constructs have found their way into mainstream languages such as Java and C#. In these languages, first-order parametric polymorphism is usually called generics. From "Generics of a Higher Kind", Adriaan Moors, Frank Piessens, and Martin Odersky Generic programming is a style of computer programming in which algorithms are written in terms of to-be-specified-later types that are then instantiated when needed for specific types provided as parameters. This approach, pioneered by Ada in 1983 From Wikipedia Generic Programming

  • 3D game editor with C++ support and Bullet Physics

    - by Raghav Bali
    I am very new to game development and hence the question. Is there any open-source game editor that uses Bullet Physics engine with C++ code edit support.I have read about blender but it allows python based editing(if I am not wrong here). I need an editor to quickly draw the needed objects and concentrate more on the logic on their interactions(mostly magnetism based). This(my project) is part of an already existing legacy code in C++ which is forcing the dependency. Also, is there any physics engine which provides support for magnetism? Any help will surely be great. Thanks
