  • Visual Studio 11 not 2011

    - by Daniel Moth
    A little pet peeve of mine is when people incorrectly refer to the Developer Preview (or the upcoming Beta) as Visual Studio 2011 instead of the correct Visual Studio 11. The "11" refers to the version number (internally we call it Dev11). What the product will be called when it is released is anyone's guess (it could keep the name or it could have a year appended to it, or it could be something else, who knows). Even if it does have a year appended to the name, I think it is a safe bet it won't be last year! For reference, version 10 was the previous version of Visual Studio which happened to be released in 2010, hence it got the name Visual Studio 2010. That is what confuses new people to this product I guess... they think that the two-digit number matches the year, just because it coincided like that last year. (btw, internally we called it Dev10). For further reference, older releases were: Visual Studio 2008 (v9) aka "Orcas", Visual Studio 2005 (v8) aka "Whidbey", Visual Studio .NET 2003 (v7.1) aka "Everett", and Visual Studio .NET 2002 (v7) aka "Rainier". Before that, we were in the pre-.NET era with Visual Studio 6 (where the version and the product name matched, without the year appended to the name). So next time you hear someone saying "Visual Studio 2011", point them to this post for some mini-education... thanks. Comments about this post by Daniel Moth welcome at the original blog.

  • How do I completely self study computer science?

    - by Optimus
    Being a completely self taught programmer I would like it if I could better myself by self-learning computer science course taught to a typical CS grad. Finding different resources on internet has been easy, there is of course MIT open course ware, and there are Coursera courses from Stanford and other universities. There are numerous other open resources scattered around the Internet and some good books that are repeatedly recommended. I have been learning a lot but my study is heavily fragmented, which really bugs me, I would love If somewhere I could find a path I should follow and a stack I should limit myself to so that I can be sure about what essential parts of computer science I have studied and systematically approach those I haven't. The problem with Wikipedia is it doesn't tell you whats essential but insists on being a complete reference. MIT open course ware for Computer science and Electrical Engg. has a huge list of courses also not telling you what courses are essential and what optional as per person's interest/requirement. I found no mention of an order in which one should study different subjects. What I would love is to create a list that I can follow like this dummy one SUBJECTS DONE Introduction to Computer Science * Introduction to Algorithms * Discrete Mathematics Adv. Discrete Mathematics Data structures * Adv. Algorithms ... As you can clearly see I have little idea of what specific subjects computer science consists of. It would be hugely helpful even if some one pointed out essential courses from MIT Course ware ( + essential subjects not present at MIT OCW) in a recommended order of study. I'll list the Posts I already went through (and I didn't get what I was looking for there) Computer science curriculum for non-CS major? - top answer says it isn't worth studying cse How can a self-taught programmer learn more about Computer Science? - points to MIT OCW Studying computer science - what am I getting myself into? Overview of computer science, programming

  • Sucky MSTest and the "WaitAll for multiple handles on a STA thread is not supported" Error

    - by Anne Bougie
    If you are doing any multi-threading and are using MSTest, you will probably run across this error. For some reason, MSTest by default runs in STA threading mode. WTF, Microsoft! Why so stuck in the old COM world?  When I run the same test using NUnit, I don't have this problem. Unfortunately, my company has chosen MSTest, so I have a lot of testing problems. NUnit is so much better, IMO. After determining that I wasn't referencing any unmanaged code that would flip the thread into STA, which can also cause this error, the only thing left was the testing suite I was using. I dug around a little and found this obscure setting for the Test Run Config settings file that you can't set using its interface. You have to open it up as a text file and add the following setting:  <ExecutionThread apartmentState="MTA" /> This didn't break any other tests, so I'm not sure why it's not the default, or why there is nothing in the test run configuration app to change this setting. Here is the code I was testing:  public void ProcessTest(ProcessInfo[] infos) {    WaitHandle[] waits = new WaitHandle[infos.Length];    int i = 0;    foreach (ProcessInfo info in infos)    {       AutoResetEvent are = new AutoResetEvent(false);       info.Are = are;       waits[i++] = are;         Processor pr = new Processor();       WaitCallback callback = pr.ProcessTest;       ThreadPool.QueueUserWorkItem(callback, info);    }      WaitHandle.WaitAll(waits); }

  • When Your Boss Doesn't Want you to Succeed

    - by Phil Factor
    You're working hard to get an application finished. You are programming long into the evenings sometimes, and eating sandwiches at your desk instead of taking a lunch break. Then one day you glance up at the IT manager, serene in his mysterious round of meetings, and think 'Does he actually care whether this project succeeds or not?'. The question may seem absurd. Of course the project must succeed. The truth, as always, is often far more complex. Your manager may even be doing his best to make sure you don't succeed. Why? There have always been rich pickings for the unscrupulous in IT.  In extreme cases, where administrators struggle with scarcely-comprehended technical issues, huge sums of money can be lost and gained without any perceptible results. In a very few cases can fraud be proven: most of the time, the intricacies of the 'game' are such that one can do little more than harbor suspicion.  Where does over-enthusiastic salesmanship end and fraud begin? The Business of Information Technology provides rich opportunities for White-collar crime. The poor developer has his, or her, hands full with the task of wrestling with the sheer complexity of building an application. He, or she, has no time for following the complexities of the chicanery of the management that is directing affairs.  Most likely, the developers wouldn't even suspect that their company management had ulterior motives. I'll illustrate what I mean with an entirely fictional, hypothetical, example. The Opportunist and the Aged Charities often do good, unexciting work that is funded by the income from a bequest that dates back maybe hundreds of years.  In our example, it isn't exciting work, for it involves the welfare of elderly people who have fallen on hard times.  Volunteers visit, giving a smile and a chat, and check that they are all right, but are able to spend a little money on their discretion to ameliorate any pressing needs for these old folk.  The money is made to work very hard and the charity averts a great deal of suffering and eases the burden on the state. Daisy hears the garden gate creak as Mrs Rainer comes up the path. She looks forward to her twice-weekly visit from the nice lady from the trust. She always asked ‘is everything all right, Love’. Cheeky but nice. She likes her cheery manner. She seems interested in hearing her memories, and talking about her far-away family. She helps her with those chores in the house that she couldn’t manage and once even paid to fill the back-shed with coke, the other year. Nice, Mrs. Rainer is, she thought as she goes to open the door. The trustees are getting on in years themselves, and worry about the long-term future of the charity: is it relevant to modern society? Is it likely to attract a new generation of workers to take it on. They are instantly attracted by the arrival to the board of a smartly dressed University lecturer with the ear of the present Government. Alain 'Stalin' Jones is earnest, persuasive and energetic. The trustees welcome him to the board and quickly forgive his humorless political-correctness. He talks of 'diversity', 'relevance', 'social change', 'equality' and 'communities', but his eye is on that huge bequest. Alain first came to notice as a Trotskyite union official, who insinuated himself into one of the duller Trades Unions and turned it, through his passionate leadership, into a radical, headline-grabbing organization.  Middle age, and the rise of European federal socialism, had brought him quiet prosperity and charcoal suits, an ear in the current government, and a wide influence as a member of various Quangos (government bodies staffed by well-paid unelected courtiers).  He was employed as a 'consultant' by several organizations that relied on government contracts. After gaining the confidence of the trustees, and showing a surprising knowledge of mundane processes and the regulatory framework of charities, Alain launches his plan.  The trust will expand their work by means of a bold IT initiative that will coordinate the interventions of several 'caring agencies', and provide  emergency cover, a special Website so anxious relatives can see how their elderly charges are doing, and a vastly more efficient way of coordinating the work of the volunteer carers. It will also provide a special-purpose site that gives 'social networking' facilities, rather like Facebook, to the few elderly folk on the lists with access to the internet. The trustees perk up. Their own experience of the internet is restricted to the occasional scanning of railway timetables, but they can see that it is 'relevant'. In his next report to the other trustees, Alain proudly announces that all this glamorous and exciting technology can be paid for by a grant from the government. He admits darkly that he has influence. True to his word, the government promises a grant of a size that is an order of magnitude greater than any budget that the trustees had ever handled. There was the understandable proviso that the company that would actually do the IT work would have to be one of the government's preferred suppliers and the work would need to be tendered under EU competition rules. The only company that tenders, a multinational IT company with a long track record of government work, quotes ten million pounds for the work. A trustee questions the figure as it seems enormous for the reasonably trivial internet facilities being built, but the IT Salesmen dazzle them with presentations and three-letter acronyms until they subside into quiescent acceptance. After all, they can’t stay locked in the Twentieth century practices can they? The work is put in hand with a large project team, in a splendid glass building near west London. The trustees see rooms of programmers working diligently at screens, and who talk with enthusiasm of the project. Paul, the project manager, looked through his resource schedule with growing unease. His initial excitement at being given his first major project hadn’t lasted. He’d been allocated a lackluster team of developers whose skills didn’t seem right, and he was allowed only a couple of contractors to make good the deficit. Strangely, the presentation he’d given to his management, where he’d saved time and resources with a OTS solution to a great deal of the development work, and a sound conservative architecture, hadn’t gone down nearly as big as he’d hoped. He almost got the feeling they wanted a more radical and ambitious solution. The project starts slipping its dates. The costs build rapidly. There are certain uncomfortable extra charges that appear, such as the £600-a-day charge by the 'Business Manager' appointed to act as a point of liaison between the charity and the IT Company.  When he appeared, his face permanently split by a 'Mr Sincerity' smile, they'd thought he was provided at the cost of the IT Company. Derek, the DBA, didn’t have to go to the server room quite some much as he did: but It got him away from the poisonous despair of the development group. Wave after wave of events had conspired to delay the project.  Why the management had imposed hideous extra bureaucracy to cover ISO 9000 and 9001:2008 accreditation just as the project was struggling to get back on-schedule was  beyond belief.  Then  the Business manager was coming back with endless changes in scope, sorrowing saying that the Trustees were very insistent, though hopelessly out in touch with the reality of technical challenges. Suddenly, the costs mount to the point of consuming the government grant in its entirety. The project remains tantalizingly just out of reach. Alain Jones gives an emotional rallying speech at the trustees review meeting, urging them not to lose their nerve. Sadly, the trustees dip into the accumulated capital of the trust, the seed-corn of all their revenues, in order to save the IT project. A few months later it is all over. The IT project is never delivered, even though it had seemed so incredibly close.  With the trust's capital all gone, the activities it funded have to be terminated and the trust becomes just a shell. There aren't even the funds to mount a legal challenge against the IT company, even had the trust's solicitor advised such a foolish thing. Alain leaves as suddenly as he had arrived, only to pop up a few months later, bronzed and rested, at another charity. The IT workers who were permanent employees are dispersed to other projects, and the contractors leave to other contracts. Within months the entire project is but a vague memory. One or two developers remain  puzzled that their managers had been so obstructive when they should have welcomed progress toward completion of the project, but they put it down to incompetence and testosterone. Few suspected that they were actively preventing the project from getting finished. The relationships between the IT consultancy, and the government of the day are intricate, and made more complex by the Private Finance initiatives and political patronage.  The losers in this case were the taxpayers, and the beneficiaries of the trust, and, perhaps the soul of the original benefactor of the trust, whose bid to give his name some immortality had been scuppered by smooth-talking white-collar political apparatniks.  Even now, nobody is certain whether a crime was ever committed. The perfect heist, I guess. Where’s the victim? "I hear that Daisy’s cottage is up for sale. She’s had to go into a care home.  She didn’t want to at all, but then there is nobody to keep an eye on her since she had that minor stroke a while back.  A charity used to help out. The ‘social’ don’t have the funding, evidently for community care. Yes, her old cat was put down. There was a good clearout, and now the house is all scrubbed and cleared ready for sale. The skip was full of old photos and letters, memories. No room in her new ‘home’."

  • MVVM Light V3 released at #MIX10

    - by Laurent Bugnion
    During my session “Understanding the MVVM pattern” at MIX10 in Vegas, I showed some components of the MVVM Light toolkit V3, which gave me the occasion to announce the release of version 3. This version has been in alpha stage for a while, and has been tested by many users. it is very stable, and ready for a release. So here we go! What’s new What’s new in MVVM Light Toolkit V3 is the topic of the next post. Cleaning up I would recommend cleaning up older versions before installing V3. I prepared a page explaining how to do that manually. Unfortunately I didn’t have time to create an automatic cleaner/installer, this is very high on my list but with the book and the conferences going on, it will take a little more time. Cleaning up is recommended because I changed the name of some DLLs to avoid some confusion (between the WPF3.5 and WPF4 version, as well as between the SL3 and SL4 versions). More details in the section titled “Compatibility”. Installation Installing MVVM Light toolkit is the manual process of unzipping a few files. The installation page has been updated to reflect the newest information. Compatibility MVVM Light toolkit V3 has components for the following environments and frameworks: Visual Studio 2008: Silverlight 3 Windows Presentation Foundation 3.5 SP1 Expression Blend 3 Silverlight 3 Windows Presentation Foundation 3.5 SP1 Visual Studio 2010 RC Silverlight 3 Silverlight 4 Windows Presentation Foundation 3.5 SP1 Windows Presentation Foundation 4 Silverlight for Windows Phone 7 series Expression Blend 4 beta Silverlight 3 Silverlight 4 Windows Presentation Foundation 3.5 SP1 Windows Presentation Foundation 4 Feedback As usual I welcome your constructive feedback. If you want the issue to be discussed in public, the best way is through the discussion page on the Codeplex site. if you wish to keep the conversation private, please check my Contact page for ways to talk to me. Video, tutorials There are a few new videos and tutorials available for the MVVM Light toolkit. The material is listed on the Get Started page, under “tutorials”.   Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

  • Minty Bug: Build an FM Bug Inside a Mint Container

    - by ETC
    Electronics projects that have real world (and showing off to your friends) potential are the most fun; today we take a look at a clever FM bug design hidden in a mint container. At PyroElectro Projects they wanted to try something new with the whole electronics-in-mint-container genre. They opted to turn a container of Ice Breakers Frost mints (the Ice Breakers response to Altoid Mints, presumably) into a small FM bug. The most clever part of the design is that the container still holds mints. Aside from a small black dot on the back of the case you’d have little reason to believe it was anything buy a box of mints. Check out the video below to see the mint container unpacked and the hidden electronics payload revealed: If you’re interested in the project hit up the link below for additional information.

  • Code Bubbles: Disruption comes to the IDE

    - by andrewbrust
    If you’re like me, you might see the open source Eclipse IDE as a copy or, more generously, a port of the Microsoft’s Visual Studio for the non-.NET world.  It’s not that Microsoft invented the IDE (I would credit Borland with that), but they really took the idea and ran with it for the first version of Visual Studio .NET in 2002.  The question is whether someone outside of Microsoft could take the modern IDE yet another major step forward in both principle and productivity. I think that has actually happened already, and I think the innovator in question is a second-year Computer Science PhD student at Brown, named Andrew Bragdon.  His project, which he calls Code Bubbles, is an IDE that allows for editing, debugging and exploration of code in “bubbles” which remind me a little bit of the discrete note tiles on OneNote…but they’re much more than that.  Bubbles actually allow for call stack traversal, saved debug sessions, sophisticated breakpoint and value watch behaviors and more.  And because bubbles, unlike windows, are borderless, and focus on code fragments rather than whole files, the de-cluttering effect is unbelievably liberating.  The best way to understand what Code Bubbles does is to watch the screencast video:     Code Bubbles is an IDE for Java development.  Why didn’t Microsoft come up with something like this for .NET devs?  Between the existing features in Visual Studio 2010, its WPF code editor, and the fact that OneNote’s UI bears some affinity to Code Bubbles’, it’s interesting that Microsoft still has not thought outside of its own “box” to get us something like this. Heck, that’s easy for me to say.  But it’s easy for you to say that you’d like something like this in Visual Studio sometime soon.  That’s because the ASP.NET site within UserVoice is taking votes on this very issue.  Just click this link and vote! Thanks to my fellow Microsoft Regional Director Sondre Bjellås for making me aware of Code Bubbles, and to RD Steve Smith for creating the UserVoice voting option.

  • Manipulating Human Tasks (for testing) by Mark Nelson

    - by JuergenKress
    A few months ago, while working on a BPM migration, I had the need to look at the status of human tasks, and to manipulate them – essentially to just have a single user take random actions on them at some interval, to help drive a set of processes that were being tested. To do this, I wrote a little utility called httool.  It reuses some of the core domain classes from my custom worklist sample (with minimal changes to make it a remote client instead of a local one). I have not got around to documenting it yet, but it is pretty simple and fairly self explanatory.  So I thought I would go ahead and share it with folks, in case anyone is interested in playing with it. You can get the code from my ci-samples repository on java.net: git clone git://java.net/ci4fmw~ci-samples It is in the httool directory. I do plan to get back to this “one day” and enhance it to be more intelligent – target particular task types, update the payload, follow a set of “rules” about what action to take – so that I can use it for more driving more interesting test scenarios.  If anyone is feeling generous with their time, and interested, please feel free to join the java.net project and hack away to your heart’s content.

  • Remastered King’s Quest Games Offer Classic Gaming on Modern Machines

    - by ETC
    If you were a fan of the King’s Quest series of adventure games from the 1980s and 1990s, you’ll be thrilled to see them remastered with enhanced graphics, polished voice acting, and more. Gaming studio AGD Interactive has been engaged in a multi-year project to remaster and freely release the classic King’s Quest games. They started with King’s Quest I in 2001, moved on to King’s Quest II, and just recently released King’s Quest III (see in the screenshot above). The gameplay for all three games is excellent and really captures the feel of the original games (with better graphics, quality voice acting, and adjustments made for modern computers). When you run the game you first get a small pre-launch console. There you can make adjusts to the game before launching it. We’d recommend you enable the pixel doubling filter. It make the game a little blockier (hey you are playing a 1980s remake!) but it fills up high resolution monitors more effectively.

  • How to Disable Touchpad tap in Toshiba Tecra R850 in Oneiric

    - by Kibi
    I know there's a lot of similar questions, but nothing I have tried here works yet - perhaps I was doing it wrong. New Laptop - Toshiba Tecra R850 with an install of Oneiric. Mostly things are working well, but I have a problem with the touchpad (or whatever it's called) - whenever I use it for moving the mouse pointer I accidentally tap on it - basically I am clicking all over the place by accident. So I want to disable the tap-as-click (after all, I have buttons for clicks too). I open up "Mouse and Touchpad" and on the Touchpad tab I check "Disable touchpad when typing" and UNcheck "Enable mouse clicks with touchpad". This does not achieve anything. The only piece of code I had which worked at all was to completely disable the touchpad by removing the driver - but that is no use since I WANT the mousing ability, just not the tap. In fact, even that would be good if I could still use the little blue stick thing and the other buttons - but it disabled them too. Tried installing touchpad indicator but it didn't seem to want to install. There were suggestions to put stuff into /usr/share/X11/xorg.conf.d so I edited 50-synaptics.conf and added the line Option "TapButton1" "0" But it didn't work and I'm not surprised since the place, syntax and values were all a guess really... Any ideas? This is really annoying. Thanks Kibi

  • SQL SERVER – Introduction to PERCENTILE_CONT() – Analytic Functions Introduced in SQL Server 2012

    - by pinaldave
    SQL Server 2012 introduces new analytical function PERCENTILE_CONT(). The book online gives following definition of this function: Computes a specific percentile for sorted values in an entire rowset or within distinct partitions of a rowset in Microsoft SQL Server 2012 Release Candidate 0 (RC 0). For a given percentile value P, PERCENTILE_DISC sorts the values of the expression in the ORDER BY clause and returns the value with the smallest CUME_DIST value (with respect to the same sort specification) that is greater than or equal to P. If you are clear with understanding of the function – no need to read further. If you got lost here is the same in simple words – it is lot like finding median with percentile value. Now let’s have fun following query: USE AdventureWorks GO SELECT SalesOrderID, OrderQty, ProductID, PERCENTILE_CONT(0.5) WITHIN GROUP (ORDER BY ProductID) OVER (PARTITION BY SalesOrderID) AS MedianCont FROM Sales.SalesOrderDetail WHERE SalesOrderID IN (43670, 43669, 43667, 43663) ORDER BY SalesOrderID DESC GO The above query will give us the following result: You can see that I have used PERCENTILE_COUNT(0.5) in query, which is similar to finding median. Let me explain above diagram with little more explanation. The defination of median is as following: In case of Even Number of elements = In ordered list add the two digits from the middle and devide by 2 In case of Odd Numbers of elements = In ordered list select the digits from the middle I hope this example gives clear idea how PERCENTILE_CONT() works.

  • Does OSB has any database dependency?

    - by Manoj Neelapu
    Major functionality of OSB is database independent. Most of the internal data-structures that re required by OSB are stored in-memory.Reporting functionality of OSB requires DB tables be accessible.http://download.oracle.com/docs/cd/E14571_01/doc.1111/e15017/before.htm#BABCJHDJ It should hover be noted that we can still run OSB with out creating any tables on database.In such cases the reporting functionality cannot be used where as other functions in OSB will work just as fine.We also see few errors in the log file indicating the absence of these tables which we can ignore.  If reporting function is required we will have to install few tables. http://download.oracle.com/docs/cd/E14571_01/doc.1111/e15017/before.htm#BABBBEHD indicates running RCU recommended. OSB reporting tables are bundled along with SOA schema in RCU. OSB requires two simple tables for reporting functionality and installing complete SOA schema is little far fetched. SOA schema contains lot of tables which OSB doesn't require at all. More over OSB tables are too simple to require a tool like an RCU.Solution to it would be to manually create those tables required for OSB. To make  life easier the definition of tables is available in dbscripts folder under OSB_HOME.eg. D:\Oracle\Middleware\osb\11gPS2\Oracle_OSB1\dbscripts. $OSB_HOME=D:\Oracle\Middleware\osb\11gPS2\Oracle_OSB1If you are not planning to use reporting feature in OSB, then we can also delete the JDBC data sources that comes along with standard OSB domain.WLST script to delete cgDataSources from OSB domain . OSB will work fine with out DB tables and JDBC Datasource.

  • Getting Query Parameters in Javascript

    - by PhubarBaz
    I find myself needing to get query parameters that are passed into a web app on the URL quite often. At first I wrote a function that creates an associative array (aka object) with all of the parameters as keys and returns it. But then I was looking at the revealing module pattern, a nice javascript design pattern designed to hide private functions, and came up with a way to do this without even calling a function. What I came up with was this nice little object that automatically initializes itself into the same associative array that the function call did previously. // Creates associative array (object) of query params var QueryParameters = (function() {     var result = {};     if (window.location.search)     {         // split up the query string and store in an associative array         var params = window.location.search.slice(1).split("&");         for (var i = 0; i < params.length; i++)         {             var tmp = params[i].split("=");             result[tmp[0]] = unescape(tmp[1]);         }     }     return result; }()); Now all you have to do to get the query parameters is just reference them from the QueryParameters object. There is no need to create a new object or call any function to initialize it. var debug = (QueryParameters.debug === "true"); or if (QueryParameters["debug"]) doSomeDebugging(); or loop through all of the parameters. for (var param in QueryParameters) var value = QueryParameters[param]; Hope you find this object useful.

  • Mission 26 Captures Endeavour’s Last Trip in Stop Motion

    - by Jason Fitzpatrick
    On September 21, 2012 the Space Shuttle Endeavour was delivered to the Los Angeles International Airport and spent the next three days being slowly transported 12 miles to the California Science Center. One dedicated team of photographers captured the whole thing. Lead by Matthew Givot, the group followed the shuttle for three straight days, photographing it around the clock. The Endeavor started on Thursday night and went on until Sunday night, with very little sleep to no sleep. The only thing that kept us going was pure love of the art and adrenaline. One thing that stood out the most for me, while I was shooting, was the people of Los Angeles. It was so powerful to see the excitement on peoples faces and the pride of their home town.

  • Custom Profile Provider with Web Deployment Project

    - by Ben Griswold
    I wrote about implementing a custom profile provider inside of your ASP.NET MVC application yesterday. If you haven’t read the article, don’t sweat it.  Most of the stuff I write is rubbish anyway. Since you have joined me today, though, I might as well offer up a little tip: you can run into trouble, like I did, if you enable your custom profile provider inside of an application which is deployed using a Web Deployment Project.  Everything will run great on your local machine and you’ll probably take an early lunch because you got the code running in no time flat and the build server is happy and all tests pass and, gosh, maybe you’ll just cut out early because it is Friday after all.  But then the first user hits the integration machine and, that’s right, yellow screen of death. Lucky you, just as you’re walking out the door, the user kindly sends the exception message and stack trace: Value cannot be null. Parameter name: type Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Stack Trace: [ArgumentNullException: Value cannot be null. Parameter name: type] System.Activator.CreateInstance(Type type, Boolean nonPublic) +2796915 System.Web.Profile.ProfileBase.CreateMyInstance(String username, Boolean isAuthenticated) +76 System.Web.Profile.ProfileBase.Create(String username, Boolean isAuthenticated) +312 User error?  Not this time. Damn! One hour later… you notice the harmless “Treat as library component (remove the App_Code.compiled file)” setting on the Output Assemblies Tab of your Web Deployment Project. You have no idea why, but you uncheck it.  You test and everything works great both locally and on the integration machine.  Application users think you’re the best and you’re still going to catch the last half hour of happy hour.  Happy Friday.

  • Microsoft Test Manager error in displaying test steps caused by malware

    - by terje
    Sometimes the tool is blamed for errors which are not the fault of the tool – this is one such story.  It was however, not so easy to get to the bottom of it, so I hope sharing this story can help some others. One of our test developers started to get this message inside the test steps part of a test case in the MTM. saying “Could not load file or assembly ‘0 bytes from System, Version=4.0.0.0,……..” The same error came up inside Visual Studio when we opened a test case there. Then we noted a similar error on another piece of software – this error: A System.BadImageFormatException, and same message as above, but just for framework 2.0. We found this  description which pointed to a malware problem (See bottom of that post), that is a fake anti-spyware program called “Additional Guard”.  We checked the computer in question using Malwarebytes Anti-Malware tool.  It found and cleaned out 753 registry keys!!  After this cleanup operation the error was gone.  This is a great tool !  The “Additional Guard” program had been inadvertently installed, and then uninstalled afterwards, but the corrupted keys were of course not removed.  We also noted that this computer had full corporate virus scanning and malware protection, but still this nasty little thing still slipped through.

  • Elevating Customer Experience through Enterprise Social Networking

    - by john.brunswick
    I am not sure about most people, but I really dislike automated call center routing systems. They are impersonal and convey a sense that the company I am dealing with does not see the value of providing customer service that increases positive perception of their brand. By the time I am connected with a live support representative I am actually more frustrated than before I originally dialed. Each time a company interacts with its customers or prospects there is an opportunity to enhance that relationship. Technical enablers like call center routing systems can be a double edged sword - providing process efficiencies, but removing the human context of some interactions that can build a lot of long term value and create substantial repeat business. Certain web systems, available through "chat with a representative" now links on some web sites, provide a quick and easy way to get in touch with someone and cut down on help desk calls, but miss the opportunity to deliver an even more personal experience to customers and prospects. As more and more users head to the web for self-service and product information, the quality of this interaction becomes critical to supporting a company's brand image and viability. It takes very little effort to go a step further and elevate customer experience, without adding significant cost through social enterprise software technologies. Enterprise Social Networking Social networking technologies have slowly gained footholds in the enterprise, evolving from something that people may have been simply curious about, to tools that have started to provide tangible value in the enterprise. Much like instant messaging, once considered a toy in the enterprise, expertise search, blogs as communications tools, wikis for tacit knowledge sharing are all seeing adoption in a way that is directly applicable to the business and quickly adding value. So where does social networking come in when trying to enhance customer experience?

  • Elastic versus Distributed in caching.

    - by Mike Reys
    Until now, I hadn't heard about Elastic Caching yet. Today I read Mike Gualtieri's Blog entry. I immediately thought about Oracle Coherence and got a little scare throughout the reading. Elastic Caching is the next step after Distributed Caching. As we've always positioned Coherence as a Distributed Cache, I thought for a brief instance that Oracle had missed a new trend/technology. But then I started reading the characteristics of an Elastic Cache. Forrester definition: Software infrastructure that provides application developers with data caching services that are distributed across two or more server nodes that consistently perform as volumes grow can be scaled without downtime provide a range of fault-tolerance levels Hey wait a minute, doesn't Coherence fullfill all these requirements? Oh yes, I think it does! The next defintion in the article is about Elastic Application Platforms. This is mainly more of the same with the addition of code execution. Now there is analytics functionality in Oracle Coherence. The analytics capability provides data-centric functions like distributed aggregation, searching and sorting. Coherence also provides continuous querying and event-handling. I think that when it comes to providing an Elastic Application Platform (as in the Forrester definition), Oracle is close, nearly there. And what's more, as Elastic Platform is the next big thing towards the big C word, Oracle Coherence makes you cloud-ready ;-) There you go! Find more info on Oracle Coherence here.

  • How to learn ASP.NET MVC without learning ASP.NET Web forms

    - by Naif
    First of all, I am not a web developer but I can say that I understand in general the difference between PHP, ASP.NET, etc. I have played a little with ASP.NET and C# as well, however, I didn't continue the learning path. Now I'd like to learn ASP.NET MVC but there is no a book for a beginner in ASP.NET MVC so I had a look at the tutorials but it seems that I need to learn C# first and SQL Server and HTML, am I right? So please tell me how can I learn ASP.NET MVC directly (I mean without learning ASP.NET Web forms). What do I need to learn (You can assume that I am an absolute beginner). Update: It is true that i can find ASP.NET MVC tutorial that explain ASP.NET MVC, but I used to find ASP.NET web forms books that explain SQL and C# at the same time and take you step by step. In ASP.NET MVC I don't know how can I start! How can I learn SQL in its own and C# in its own and then combine them with ASP.NET MVC!

  • SPARC64 VII+ Processor Core License Factor Reduced by 33%

    - by john.shell
    The Oracle processor core license factor has been a popular topic the last few months.  For those partners new to Oracle software licensing, the processor core license factor determines the number licensed CPUs that are required when running Oracle software (those charged on a per-CPU basis) on multi-core processors.My last entry talked about the core factor reduction for our T3 processor.  The core license factor for our newly announced SPARC64 VII+ processor is 0.5, which is a 33% reduction from the 0.75 rate used with our SPARC64 VI and VII processors.What does this mean for our partners?  Increased opportunity.  This change, similar to our T3-based systems, means that our hardware is the preferred platform for Oracle software. Still a little dizzy on the breadth of Oracle's software offering?  Do a simple scan of Oracle's software price lists. Consider this your target market.This change allows you to focus on total solution price or price/performance, not server prices or per core performance (a standard IBM sales tactic). That's the offensive side of the game.  Don't forget your defense.  One of the biggest customer benefits around the M-Series is investment protection.  The combination of a simple processor/board upgrade, along with a reduction in processor core license factor, makes upgrading one of the best financial moves for our customers.    One reminder.  The update to the processor core license factor only applies to the new VII+ processor - NOT the SPARC64 VI or VII processors.  You can find the official table here.

  • The fastest way to resize images from ASP.NET. And it’s (more) supported-ish.

    - by Bertrand Le Roy
    I’ve shown before how to resize images using GDI, which is fairly common but is explicitly unsupported because we know of very real problems that this can cause. Still, many sites still use that method because those problems are fairly rare, and because most people assume it’s the only way to get the job done. Plus, it works in medium trust. More recently, I’ve shown how you can use WPF APIs to do the same thing and get JPEG thumbnails, only 2.5 times faster than GDI (even now that GDI really ultimately uses WIC to read and write images). The boost in performance is great, but it comes at a cost, that you may or may not care about: it won’t work in medium trust. It’s also just as unsupported as the GDI option. What I want to show today is how to use the Windows Imaging Components from ASP.NET APIs directly, without going through WPF. The approach has the great advantage that it’s been tested and proven to scale very well. The WIC team tells me you should be able to call support and get answers if you hit problems. Caveats exist though. First, this is using interop, so until a signed wrapper sits in the GAC, it will require full trust. Second, the APIs have a very strong smell of native code and are definitely not .NET-friendly. And finally, the most serious problem is that older versions of Windows don’t offer MTA support for image decoding. MTA support is only available on Windows 7, Vista and Windows Server 2008. But on 2003 and XP, you’ll only get STA support. that means that the thread safety that we so badly need for server applications is not guaranteed on those operating systems. To make it work, you’d have to spin specialized threads yourself and manage the lifetime of your objects, which is outside the scope of this article. We’ll assume that we’re fine with al this and that we’re running on 7 or 2008 under full trust. Be warned that the code that follows is not simple or very readable. This is definitely not the easiest way to resize an image in .NET. Wrapping native APIs such as WIC in a managed wrapper is never easy, but fortunately we won’t have to: the WIC team already did it for us and released the results under MS-PL. The InteropServices folder, which contains the wrappers we need, is in the WicCop project but I’ve also included it in the sample that you can download from the link at the end of the article. In order to produce a thumbnail, we first have to obtain a decoding frame object that WIC can use. Like with WPF, that object will contain the command to decode a frame from the source image but won’t do the actual decoding until necessary. Getting the frame is done by reading the image bytes through a special WIC stream that you can obtain from a factory object that we’re going to reuse for lots of other tasks: var photo = File.ReadAllBytes(photoPath); var factory = (IWICComponentFactory)new WICImagingFactory(); var inputStream = factory.CreateStream(); inputStream.InitializeFromMemory(photo, (uint)photo.Length); var decoder = factory.CreateDecoderFromStream( inputStream, null, WICDecodeOptions.WICDecodeMetadataCacheOnLoad); var frame = decoder.GetFrame(0); We can read the dimensions of the frame using the following (somewhat ugly) code: uint width, height; frame.GetSize(out width, out height); This enables us to compute the dimensions of the thumbnail, as I’ve shown in previous articles. We now need to prepare the output stream for the thumbnail. WIC requires a special kind of stream, IStream (not implemented by System.IO.Stream) and doesn’t directlyunderstand .NET streams. It does provide a number of implementations but not exactly what we need here. We need to output to memory because we’ll want to persist the same bytes to the response stream and to a local file for caching. The memory-bound version of IStream requires a fixed-length buffer but we won’t know the length of the buffer before we resize. To solve that problem, I’ve built a derived class from MemoryStream that also implements IStream. The implementation is not very complicated, it just delegates the IStream methods to the base class, but it involves some native pointer manipulation. Once we have a stream, we need to build the encoder for the output format, which could be anything that WIC supports. For web thumbnails, our only reasonable options are PNG and JPEG. I explored PNG because it’s a lossless format, and because WIC does support PNG compression. That compression is not very efficient though and JPEG offers good quality with much smaller file sizes. On the web, it matters. I found the best PNG compression option (adaptive) to give files that are about twice as big as 100%-quality JPEG (an absurd setting), 4.5 times bigger than 95%-quality JPEG and 7 times larger than 85%-quality JPEG, which is more than acceptable quality. As a consequence, we’ll use JPEG. The JPEG encoder can be prepared as follows: var encoder = factory.CreateEncoder( Consts.GUID_ContainerFormatJpeg, null); encoder.Initialize(outputStream, WICBitmapEncoderCacheOption.WICBitmapEncoderNoCache); The next operation is to create the output frame: IWICBitmapFrameEncode outputFrame; var arg = new IPropertyBag2[1]; encoder.CreateNewFrame(out outputFrame, arg); Notice that we are passing in a property bag. This is where we’re going to specify our only parameter for encoding, the JPEG quality setting: var propBag = arg[0]; var propertyBagOption = new PROPBAG2[1]; propertyBagOption[0].pstrName = "ImageQuality"; propBag.Write(1, propertyBagOption, new object[] { 0.85F }); outputFrame.Initialize(propBag); We can then set the resolution for the thumbnail to be 96, something we weren’t able to do with WPF and had to hack around: outputFrame.SetResolution(96, 96); Next, we set the size of the output frame and create a scaler from the input frame and the computed dimensions of the target thumbnail: outputFrame.SetSize(thumbWidth, thumbHeight); var scaler = factory.CreateBitmapScaler(); scaler.Initialize(frame, thumbWidth, thumbHeight, WICBitmapInterpolationMode.WICBitmapInterpolationModeFant); The scaler is using the Fant method, which I think is the best looking one even if it seems a little softer than cubic (zoomed here to better show the defects): Cubic Fant Linear Nearest neighbor We can write the source image to the output frame through the scaler: outputFrame.WriteSource(scaler, new WICRect { X = 0, Y = 0, Width = (int)thumbWidth, Height = (int)thumbHeight }); And finally we commit the pipeline that we built and get the byte array for the thumbnail out of our memory stream: outputFrame.Commit(); encoder.Commit(); var outputArray = outputStream.ToArray(); outputStream.Close(); That byte array can then be sent to the output stream and to the cache file. Once we’ve gone through this exercise, it’s only natural to wonder whether it was worth the trouble. I ran this method, as well as GDI and WPF resizing over thirty twelve megapixel images for JPEG qualities between 70% and 100% and measured the file size and time to resize. Here are the results: Size of resized images   Time to resize thirty 12 megapixel images Not much to see on the size graph: sizes from WPF and WIC are equivalent, which is hardly surprising as WPF calls into WIC. There is just an anomaly for 75% for WPF that I noted in my previous article and that disappears when using WIC directly. But overall, using WPF or WIC over GDI represents a slight win in file size. The time to resize is more interesting. WPF and WIC get similar times although WIC seems to always be a little faster. Not surprising considering WPF is using WIC. The margin of error on this results is probably fairly close to the time difference. As we already knew, the time to resize does not depend on the quality level, only the size does. This means that the only decision you have to make here is size versus visual quality. This third approach to server-side image resizing on ASP.NET seems to converge on the fastest possible one. We have marginally better performance than WPF, but with some additional peace of mind that this approach is sanctioned for server-side usage by the Windows Imaging team. It still doesn’t work in medium trust. That is a problem and shows the way for future server-friendly managed wrappers around WIC. The sample code for this article can be downloaded from: http://weblogs.asp.net/blogs/bleroy/Samples/WicResize.zip The benchmark code can be found here (you’ll need to add your own images to the Images directory and then add those to the project, with content and copy if newer in the properties of the files in the solution explorer): http://weblogs.asp.net/blogs/bleroy/Samples/WicWpfGdiImageResizeBenchmark.zip WIC tools can be downloaded from: http://code.msdn.microsoft.com/wictools To conclude, here are some of the resized thumbnails at 85% fant:

  • OpenGL ES 2 shaders for drawing buildings and roads like Google Maps does

    - by Pris
    I'm trying to create a shader that'll give me an effect similar to what buildings and roads look like on 3D Google Maps. You can see the effect interactively if you enable WebGL at maps.google.com, and I also found a couple of screenshots that illustrate what I'm trying to achieve: Thing I noticed: There's some kind of transparency thing going on with the roads/ground and the buildings, but not between the buildings themselves. It might be that they're rendering the ground and roads after the buildings with the right blend functions to achieve that effect. If you look closely, you'll see parts of the building profiles have an outline. The roads also have nice clean outlines. There are a lot of techniques for outlining things with shaders... but I'm curious to find out what might have been used in this case considering mobile hardware and a large number of entities with outlines (roads and buildings) I'm assuming that for the lighting, some sort of simple diffuse per-vertex shader is being used for the buildings though I could be wrong. I'm especially curious about the 'look' they achieved with buildings (clean, precise outlines/shading). It reminds me a little of what you'd see when designing stuff with CAD applications like SolidWorks: I'd appreciate any advice on achieving this kind of look with ES 2 shaders.
