  • Can Microsoft Build Appliances?

    - by andrewbrust
    Billy Hollis, my Visual Studio Live! colleague and fellow Microsoft Regional Director said recently, and I am paraphrasing, that the computing world, especially on the consumer side, has shifted from one of building hardware and software that makes things possible to do, to building products and technologies that make things easy to do.  Billy crystalized things perfectly, as he often does. In this new world of “easy to do,” Apple has done very well and Microsoft has struggled.  In the old world, customers wanted a Swiss Army Knife, with the most gimmicks and gadgets possible.  In the new world, people want elegantly cutlery.  They may want cake cutters and utility knives too, but they don’t want one device that works for all three tasks.  People don’t want tools, they want utensils.  People don’t want machines.  They want appliances. Microsoft Appliances: They Do Exist Microsoft has built a few appliance-like devices.  I would say XBox 360 is an appliance,  It’s versatile, mind you, but it’s the kind of thing you plug in, turn on and use, as opposed to set-up, tune, and open up to upgrade the internals.  Windows Phone 7 is an appliance too.  It’s a true smartphone, unlike Windows Mobile which was a handheld computer with a radio stack.  Zune is an appliance too, and a nice one.  It hasn’t attained much traction in the market, but that’s probably because the seminal consumer computing appliance -- the iPod – got there so much more quickly. In the embedded world, Mediaroom, Microsoft’s set-top product for the cable industry (used by AT&T U-Verse and others) is an appliance.  So is Microsoft’s Sync technology, used in Ford automobiles.  Even on the enterprise side, Microsoft has an appliance: SQL Server Parallel Data Warehouse Edition (PDW) combines Microsoft software with select OEMs’ server, networking and storage hardware.  You buy the appliance units from the OEMs, plug them in, connect them and go. I would even say that Bing is an appliance.  Not in the hardware sense, mind you.  But from the software perspective, it’s a single-purpose product that you visit or run, use and then move on.  You don’t have to install it (except the iOS and Android native apps where it’s pretty straightforward), you don’t have to customize it, you don’t have to program it.  Basically, you just use it. Microsoft Appliances that Should Exist But Microsoft builds a bunch of things that are not appliances.  Media Center is not an appliance, and it most certainly should be.  Instead, it’s an app that runs on Windows 7.  It runs full-screen and you can use this configuration to conceal the fact that Windows is under it, but eventually something will cause you to abandon that masquerade (like Patch Tuesday). The next version of Windows Home Server won’t, in my opinion, be an appliance either.  Now that the Drive Extender technology is gone, and users can’t just add and remove drives into and from a single storage pool, the product is much more like a IT server and less like an appliance-premised one.  Much has been written about this decision by Microsoft.  I’ll just sum it up in one word: pity. Microsoft doesn’t have anything remotely appliance-like in the tablet category, either.  Until it does, it likely won’t have much market share in that space either.  And of course, the bulk of Microsoft’s product catalog on the business side is geared to enterprise machines and not personal appliances. Appliance DNA: They Gotta Have It. The consumerization of IT is real, because businesspeople are consumers too.  They appreciate the fit and finish of appliances at home, and they increasingly feel entitled to have it at work too.  Secure and reliable push email in a smartphone is necessary, but it isn’t enough.  People want great apps and a pleasurable user experience too.  The full Microsoft Office product is needed at work, but a PC with a keyboard and mouse, or maybe a touch screen that uses a stylus (or requires really small fingers), to run Office isn’t enough either.  People want a flawless touch experience available for the times they want to read and take quick notes.  Until Microsoft realizes this fully and internalizes it, it will suffer defeats in the consumer market and even setbacks in the business market.  Think about how slow the Office upgrade cycle is…now imagine if the next version of Office had a first-class alternate touch UI and consider the possible acceleration in adoption rates. Can Microsoft make the appliance switch?  Can the appliance mentality become pervasive at the company?  Can Microsoft hasten its release cycles dramatically and shed the “some assembly required” paradigm upon which many of its products are based?  Let’s face it, the chances that Microsoft won’t make this transition are significant. But there are also encouraging signs, and they should not be ignored.  The appliances we have already discussed, especially Xbox, Zune and Windows Phone 7, are the most obvious in this regard.  The fact that SQL Server has an appliance SKU now is a more subtle but perhaps also more significant outcome, because that product sits so smack in the middle of Microsoft’s enterprise stack.  Bing is encouraging too, especially given its integrated travel, maps and augmented reality capabilities.  As Bing gains market share, Microsoft has tangible proof that it can transform and win, even when everyone outside the company, and many within it, would bet otherwise. That Great Big Appliance in the Sky Perhaps the most promising (and evolving) proof points toward the appliance mentality, though, are Microsoft’s cloud offerings -- Azure and BPOS/Office 365.  While the cloud does not represent a physical appliance (quite the opposite in fact) its ability to make acquisition, deployment and use of technology simple for the user is absolutely an embodiment of the appliance mentality and spirit.  Azure is primarily a platform as a service offering; it doesn’t just provide infrastructure.  SQL Azure does likewise for databases.  And Office 365 does likewise for SharePoint, Exchange and Lync. You don’t administer, tune and manage servers; instead, you create databases or site collections or mailboxes and start using them. Upgrades come automatically, and it seems like releases will come more frequently.  Fault tolerance and content distribution is just there.  No muss.  No fuss.  You use these services; you don’t have to set them up and think about them.  That’s how appliances work.  To me, these signs point out that Microsoft has the full capability of transforming itself.  But there’s a lot of work ahead.  Microsoft may say they’re “all in” on the cloud, but the majority of the company is still oriented around its old products and models.  There needs to be a wholesale cultural transformation in Redmond.  It can happen, but product management, program management, the field and executive ranks must unify in the effort. So must partners, and even customers.  New leaders must rise up and Microsoft must be able to see itself as a winner.  If Microsoft does this, it could lock-in decades of new success, and be a standard business school case study for doing so.  If not, the company will have missed an opportunity, and may see its undoing.

  • Strange Misleading Error[XML -2018/ AC-10006] when doing the R12 Cloning

    - by [email protected]
    During the recent Multi Node to Single Node R12 Clone, Encountered an strange error. When doing the database portion of the clone. Below command 'adclonectx.pl' creates the Context file perl adclonectx.pl contextfile=$ORACLE_HOME/appsutil/SOURCE_CONTEXT_FILE.xml template=$ORACLE_HOME/appsutil/template/adxdbctx.tmp pairsfile=$ORACLE_HOME/appsutil/clone/pairsfile.txt initialnode   When running the same command, It dumped the below error,   file:/tmp/tmpCtxClone.xml<Line 1, Column 1>: XML-20108: (Fatal Error) Start of root element expected.

  • WebGL CORS error loading simple texture in Chrome

    - by mathacka
    Here's my code: function loadTexture() { textureImage = new Image(); textureImage.onload = function() { setupTexture(); } textureImage.src = "jumper2.png"; } function setupTexture() { texture = gl.createTexture(); gl.bindTexture(gl.TEXTURE_2D, texture); gl.pixelStorei(gl.UNPACK_FLIP_Y_WEBGL, true); // this next line has the error: Uncaught SecurityError: An attempt was made to break through the security policy of the user agent. gl.texImage2D(gl.TEXTURE_2D, 0, gl.RGBA, gl.RGBA, gl.UNSIGNED_BYTE, textureImage); gl.texParameteri(gl.TEXTURE_2D, gl.OES_TEXTURE_FLOAT_LINEAR, gl.NEAREST); if (!gl.isTexture(texture)) { alert("Error: Texture is invalid"); } glProgram.samplerUniform = gl.getUniformLocation(glProgram, "uSampler"); gl.uniform1i(glProgram.samplerUniform, 0); } I've researched it and it is a CORS error a "Cross-origin resource sharing" error, but it's a local file! I can't figure out what's wrong. I did make the picture using gimp, and I'm not sure the coding was right on the export, but I eliminated a previous error using "gl.OES_TEXTURE_FLOAT_LINEAR".

  • Closest location - Heapify or Build-heap

    - by Trevor Adams
    So lets say we have a set of gps data points and your current location. If asked to give the closest point to your current location we can utilize a heap with the distance being the key. Now if we update the current location, I suspect that only a few of the keys will change enough to violate the heap property. Would it be more efficient to rebuild the heap after recalculating the keys or to run heapify (assuming that only a few of the keys have changed enough). It is assumed that we don't jump around with the new location (new current location is close to the last current location).

  • How To Build An Enterprise Application - Introduction

    - by Tuan Nguyen
    An enterprise application is a software which fulfills 4 core quality attributes: Reliability Flexibility Reusability Maintainability Reliability is the ability of a system or component to perform its required functions under stated conditions for a specific period of time. Because there are no ways more than testing to make sure a system is reliability, we can exchange the term reliability with the term testability. Flexibility is the ability of changing a system's core features without violating unrelated features or components. Although flexibility can helps us to achieve interoperability easily but the opposite is not true. For example, a program might run on multiple platforms, contains logic for many scenarios but that wouldn't mean it was flexibility if it forces us rewrite code in all components when we just want to change some aspects of a feature it had. Reusability is the ability of sharing one or more system's components for another system. We should just open a component's reusability in the context in which it is used. For example, we write classes that implement UI logic and deliver them to only classes which implementing UI. Maintainability is the ability of adding or removing features to a system after it was released. Maintainability consists of many factors such as readability, analyzability, extensibility therein extensibility is critical. Maintainability requires us to write code that is longer and complexer than normal but it doesn't mean we introduce unneccessarily complex code. We always try to make our code clear and transparent to everyone. An application enterprise is built on an enterprise design which consists of two parts: low-level design and high-level design. At low-level design, it focuses on building loose-coupled classes or components. Particularly, it recommends: Each class or component undertakes only single responsibility (design based on unit test) Classes or components implement and work through interfaces (design based on contract) Dependency relationship between classes and components could be injected at run-time (design based on dependency) At high-level design, it focuses on architecting system into tiers and layers. Particularly, it recommends: Divide system into subsystems for deployment. Each subsytem is called a tier. Typical, an enterprise application would have 3 tiers as illustrated in the following figure: Arrange classes and components to logical containers called layers. Typical, an enterprise application would have 5 layers as illustrated in the following figure

  • Build a custom Ubuntu based distribution

    - by user51447
    I am working on making a custom Ubuntu 11.10 based distro.(64 bit) I am adding non open source packages, replacing packages, changed user interface from Unity to GNOME, and more changes. My system is ready, and I want to create a redistributable image for my distro. When you go to system settings - system info, you see a logo with the Ubuntu name and logo, but I want to change it to the name and logo of my distro. Also, in the boot menu, I want to change the boot entry names, and the GRUB background. And I want to change the name Ubuntu from every possible location. Also, I will be sharing it with people, so I want to make my own software repositories, like linux mint has, or any other distro has, I will purchase server space for that. Also, the I want to customize the wubi installer like linux mint did and if some uses the customized tool to install my distro from Windows, they should see the name of my distro in add or remove programs page. Any help will be appreciated!

  • IIS 7.0 404 Custom Error Page and web.config

    - by Colin
    I am having trouble with a custom 404 error page. I have a domain running a .NET proj with it's own error handling. I have a web.config running for the domain which contains: <customErrors mode="RemoteOnly"> <error statusCode="500" redirect="/Error"/> <error statusCode="404" redirect="/404"/> </customErrors> On a sub dir of that domain I am ignoring all routes there by doing routes.IgnoreRoute("Assets/{*pathInfo}"); in the .NET proj and I want to put a custom 404 error page on that and any sub dir's of Assets. The sub dir contains static content like images, css, js etc etc. So in the Error Pages section of IIS I put a redirect to an absolute URL. The web.config for that dir looks like the following: <system.webServer> <httpErrors> <remove statusCode="404" subStatusCode="-1" /> <error statusCode="404" prefixLanguageFilePath="" path="http://mydomain.com/404" responseMode="Redirect" /> </httpErrors> </system.webServer> But I navigate to an unknown URL under that dir and yet I still see the default IIS 404 page. I am also seeing an alert in IIS that reads: You have configured detailed error messages to be returned for both local and remote requests. When this option is selected, custom error configuration is not used. Does this have anything to do with the customErrors mode="RemoteOnly" in the site web.config? I have tried to overwrite the customErrors in the sub dir web.config but nothing changes. Any help would be appreciated. Thanks.

  • 503.1 Service Unavailable Error Resolution

    - by Lee Brandt
    I was having a hell of a time tonight with my IIS on my development laptop. I don’t remember doing anything to change the IIS settings. I don’t use IIS that much on my dev machine. Usually Cassini is enough for testing my development efforts but tonight I needed to replicate a problem that seems to stem from x86 v x64 mismatch, so I went to create an IIS site pointed to my dev folder. When I did, I got a “503.1 Service Unavailable Error”. First thing I did is go over all my setting to make sure I didn’t screw something up when I set up the site. It was pointing to the right place, and the app pool settings seemed to be alright. However, when I got the 503.1 error and went back to my app pool list, I saw that the app pool I was using was stopped again. I must’ve started and ran it a dozen times to verify that I wasn’t seeing things. After having a colleague look at it and not finding an answer, I started poking around Google. I cam across a post from Phil Haack about the same error. His fix was not mine, however. When I ran his command on the CLI, I didn’t see the reserved routes for HTTP.SYS there. Finally, I looked in the event viewer (where I should have looked as soon as I saw that my app pool was stopping) and saw an error in there. For the IIS-W3SVC-WP Source I saw: The worker process for application pool 'DefaultAppPool' encountered an error 'Cannot read configuration file due to insufficient permissions ' trying to read configuration data from file '\\?\C:\Windows\Microsoft.NET\Framework64\v4.0.30319\CONFIG\machine.config', line number '0'. The data field contains the error code. So I went to that path and saw a little lock on the file icon. I opened up the security tab for file properties and saw that I was missing the IIS_IUSRS group. On a machine that was working correctly, I verified that it indeed had the IIS_IUSRS group set to Read and Read & Execute allowed. So I set mine up the same and voila! Hopefully this helps somebody else, too.

  • Where can I start learning to build web applications in C#

    - by Carson Myers
    So far I've written web sites in PHP, except for a pet project of mine written in Python. I'd like to start learning C# for use on the web, but I have no idea where to start. I know nothing of .Net. Are there any good tutorials or online books etc. which give a brief intro to the .Net environment (specifically C#, and specifically for the web)? I'm not even sure what I need to install. Visual Studio I guess, but what else? Anything special, or will VS do the trick?

  • How to build a Singleton-like dependency injector replacement (Php)

    - by Erparom
    I know out there are a lot of excelent containers, even frameworks almost entirely DI based with good strong IoC classes. However, this doesn't help me to "define" a new pattern. (This is Php code but understandable to anyone) Supose we have: //Declares the singleton class bookSingleton { private $author; private static $bookInstance; private static $isLoaned = FALSE; //The private constructor private function __constructor() { $this->author = "Onecrappy Writer Ofcheap Novels"; } //Sets the global isLoaned state and also gets self instance public static function loanBook() { if (self::$isLoaned === FALSE) { //Book already taken, so return false return FALSE; } else { //Ok, not loaned, lets instantiate (if needed and loan) if (!isset(self::$bookInstance)) { self::$bookInstance = new BookSingleton(); } self::$isLoaned = TRUE; } } //Return loaned state to false, so another book reader can take the book public function returnBook() { $self::$isLoaned = FALSE; } public function getAuthor() { return $this->author; } } Then we get the singelton consumtion class: //Consumes the Singleton class BookBorrower() { private $borrowedBook; private $haveBookState; public function __construct() { this->haveBookState = FALSE; } //Use the singelton-pattern behavior public function borrowBook() { $this->borrowedBook = BookSingleton::loanBook(); //Check if was successfully borrowed if (!this->borrowedBook) { $this->haveBookState = FALSE; } else { $this->haveBookState = TRUE; } } public function returnBook() { $this->borrowedBook->returnBook(); $this->haveBookState = FALSE; } public function getBook() { if ($this->haveBookState) { return "The book is loaned, the author is" . $this->borrowedbook->getAuthor(); } else { return "I don't have the book, perhaps someone else took it"; } } } At last, we got a client, to test the behavior function __autoload($class) { require_once $class . '.php'; } function write ($whatever,$breaks) { for($break = 0;$break<$breaks;$break++) { $whatever .= "\n"; } echo nl2br($whatever); } write("Begin Singleton test", 2); $borrowerJuan = new BookBorrower(); $borrowerPedro = new BookBorrower(); write("Juan asks for the book", 1); $borrowerJuan->borrowBook(); write("Book Borrowed? ", 1); write($borrowerJuan->getAuthorAndTitle(),2); write("Pedro asks for the book", 1); $borrowerPedro->borrowBook(); write("Book Borrowed? ", 1); write($borrowerPedro->getAuthorAndTitle(),2); write("Juan returns the book", 1); $borrowerJuan->returnBook(); write("Returned Book Juan? ", 1); write($borrowerJuan->getAuthorAndTitle(),2); write("Pedro asks again for the book", 1); $borrowerPedro->borrowBook(); write("Book Borrowed? ", 1); write($borrowerPedro->getAuthorAndTitle(),2); This will end up in the expected behavior: Begin Singleton test Juan asks for the book Book Borrowed? The book is loaned, the author is = Onecrappy Writer Ofcheap Novels Pedro asks for the book Book Borrowed? I don't have the book, perhaps someone else took it Juan returns the book Returned Book Juan? I don't have the book, perhaps someone else took it Pedro asks again for the book Book Borrowed? The book is loaned, the author is = Onecrappy Writer Ofcheap Novels So I want to make a pattern based on the DI technique able to do exactly the same, but without singleton pattern. As far as I'm aware, I KNOW I must inject the book inside "borrowBook" function instead of taking a static instance: public function borrowBook(BookNonSingleton $book) { if (isset($this->borrowedBook) || $book->isLoaned()) { $this->haveBook = FALSE; return FALSE; } else { $this->borrowedBook = $book; $this->haveBook = TRUE; return TRUE; } } And at the client, just handle the book: $borrowerJuan = new BookBorrower(); $borrowerJuan-borrowBook(new NonSingletonBook()); Etc... and so far so good, BUT... Im taking the responsability of "single instance" to the borrower, instead of keeping that responsability inside the NonSingletonBook, that since it has not anymore a private constructor, can be instantiated as many times... making instances on each call. So, What does my NonSingletonBook class MUST be in order to never allow borrowers to have this same book twice? (aka) keep the single instance. Because the dependency injector part of the code (borrower) does not solve me this AT ALL. Is it needed the container with an "asShared" method builder with static behavior? No way to encapsulate this functionallity into the Book itself? "Hey Im a book and I shouldn't be instantiated more than once, I'm unique"

  • Ant trouble with environment variables on Ubuntu

    - by Inaimathi
    Having some trouble with with ant reading environment variables in Ubuntu 9.1. Specifically, the build tasks my company uses has a token like ${env.CATALINA_HOME] in the main build.xml. I set CATALINA_HOME to the correct value in /etc/environment, ~/.pam_environment and (just to be safe) my .bashrc. I can see the correct value when I run printenv from bash, or when I eval (getenv "CATALINA_HOME") in emacs. Ant refuses to build to the correct directory though; instead I get a folder named ${env.CATALINA_HOME} in the same directory as my build.xml. Any idea what's happening there, and/or how to fix it?

  • Which kind of public sitemap should I build for a search based navigation site

    - by Noam
    I have a search based navigation web-site. Each query has filters as well as sort-by. The search results point to end-pages inside the site. Each of those pages has many outlinks to other end-pages. Currently I have a XML sitemap which directs crawlers to all the end pages. I'm trying to add a silo sitemap directory to improve SEO. Assuming this is the right direction I have a couple of options: end pages sorted alphabetically. Pages by major search filters, and then divide alphabetically. Pages for every filter and cross option between them and the sort-by. Which would you recommend and why? NOTE: I'm not referring to a XML sitemap.
