  • 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.

  • 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.

  • 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.

  • 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. No matter how many times I would see the Shuttle it would never get old. This has been an amazing experience that I will never forget. My hope is that this film will show you the amount of dedicated people and teamwork that it took to get the Endeavour to its new home. Enjoy. The end result of their labor is the above video, a beautiful time-lapse video of Endeavour’s journey from the airport to its hanger at the California Science Center.

  • 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.

  • 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?

  • 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!

  • Time management and self improvement

    - by Filip
    Hi, I hope I can open a discussion on this topic as this is not a specific problem. It's a topic I hope to get some ideas on how people in similar situation as mine manage their time. OK, I'm a single developer on a software project for the last 6-8 months. The project I'm working on uses several technologies, mainly .net stuff: WPF, WF, NHibernate, WCF, MySql and other third party SDKs relevant for the project nature. My experience and knowledge vary, for example I have a lot of experience in WPF but much less in WCF. I work full time on the project and im curios on how other programmers which need to multi task in many areas manage their time. I'm a very applied type of person and prefer to code instead of doing research. I feel that doing research "might" slow down the progress of the project while I recognize that research and learning more in areas which I'm not so strong will ultimately make me more productive. How would you split up your daily time in productive coding time and time to and experiment, read blogs, go through tutorials etc. I would say that Im coding about 90%+ of my day and devoting some but very little time in research and acquiring new knowledge.

  • 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.

  • 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.

  • 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:

  • Entity Framework &amp; Transactions

    - by Sudheer Kumar
    There are many instances we might have to use transactions to maintain data consistency. With Entity Framework, it is a little different conceptually. Case 1 – Transaction b/w multiple SaveChanges(): here if you just use a transaction scope, then Entity Framework (EF) will use distributed transactions instead of local transactions. The reason is that, EF closes and opens the connection when ever required only, which means, it used 2 different connections for different SaveChanges() calls. To resolve this, use the following method. Here we are opening a connection explicitly so as not to span across multipel connections.   using (TransactionScope ts = new TransactionScope()) {     context.Connection.Open();     //Operation1 : context.SaveChanges();     //Operation2 :  context.SaveChanges()     //At the end close the connection     ts.Complete(); } catch (Exception ex) {       //Handle Exception } finally {       if (context.Connection.State == ConnectionState.Open)       {            context.Connection.Close();       } }   Case 2 – Transaction between DB & Non-DB operations: For example, assume that you have a table that keeps track of Emails to be sent. Here you want to update certain details like DataSent once if the mail was successfully sent by the e-mail client. Email eml = GetEmailToSend(); eml.DateSent = DateTime.Now; using (TransactionScope ts = new TransactionScope()) {    //Update DB    context.saveChanges();   //if update is successful, send the email using smtp client   smtpClient.Send();   //if send was successful, then commit   ts.Complete(); }   Here since you are dealing with a single context.SaveChanges(), you just need to use the TransactionScope, just before saving the context only.   Hope this was helpful!

  • 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.

  • dual boot Windows 7 and Ubuntu 11.04, black screen when loading Windows

    - by Sean
    I am proficient with Windows and not so much with Linux. Here is my story: Original system came with Windows 7, got openSUSE installed on the second hard drive, and dual boot for this setup worked fine. Wanted to switch to Windows 7 and Ubuntu 11.04 dual boot so I did a Windows system recovery and it appeared to give me back a fresh Windows 7 install. I then go to install Ubuntu 11.04 and the installer informs me I have multiple operating systems already installed. I go to the advanced partitioning option and sure enough Windows 7 is on /sda while openSUSE is still on /sdb. From here I followed this guide (How to dual-boot Linux and Ubuntu with two hard drives) after I had deleted all the openSUSE partitions on /sdb through the Allocate Drive Space tab of the installer. I make the /boot, swap, /, and /home partitions and set the GRUB into the MBR of the second disk (/dev/sdb). Everything installs fine. I reboot, Windows loads automatically, install EasyBCD and add an entry for Ubuntu into the Windows Boot Manager while assigning the type as GRUB2. Reboot the system and it now shows dual booting options for both Windows and Ubuntu. Problem is: while I can use Ubuntu fine when I try to boot into Windows it just gives me a black screen and after a little while the fans start running crazy. If I restart the computer I will sometimes get the message that my system was put into hibernation mode because the temperature got too high (90C) which I presume is in accordance with the fans going crazy. I have linked the output from the Boot Info Script below, any suggestions on how to fix this issue would be greatly appreciated!

  • Permission issues causes Unity Segmentation fault

    - by Dj Gilcrease
    I upgraded from 13.04 to 13.10 and I can boot to the unity-greeter and login just fine, but after login I just get a black screen with a cursor. I have tried following http://help.ubuntu.com/community/BinaryDriverHowto/ATI http://help.ubuntu.com/community/RadeonDriver and the manual install of the downloaded AMD drivers. All have the same affect. Also I have read Black screen after login with cursor I get a black screen after logging in ubuntu 13.04 black screen after login Ubuntu 13.10 - Black screen after login session Ubuntu 13.04 - Black screen with unresponsive cursor Upgrade to Ubuntu 13.04 Problem - Boots into Blank Black Screen All of which were no further help then the two support articles about ATI drivers So I switched back to the default drivers and went a little further into debugging, when I do ctrl+alt+F1 and login and try unity --debug > unity_start.log then ctrl+alt+F8 the screen stays black with a cursor and when I switch back ctrl+alt+F1 the contents of the log output are http://pastebin.com/rdQG4Hb0 However when I try sudo unity --debug > unity_start_root.log then ctrl+alt+F8, unity starts and the output of the log is http://pastebin.com/Yv4RD2j7 The fact that it starts as root tells be it is either a permissions issue of some required file or there is some setting that is specific to my user that is causing the SIGSEGV. So to narrow this down I activated the guest account and tried to login and got the same black screens with only a mouse cursor, so this tells me that it is not a configuration issue, but a permissions issue, so how do I narrow down which file has the wrong permissions? Also is there anything further that may help debug this issue? Ok after a few more hours of googling I found that if I add myself to the video group I can login and see the desktop, but there are lots of other permission related issues, so I am thinking something went wonky with PolicyKit during the upgrade, is there a way to reset PolicyKit settings for a user?

  • Gparted resize of an extended partition fails with error "can't have overlapping partitions".

    - by Marcus
    I just decided to install Ubuntu 12.04 alongside Windows 7 on my Dell laptop. However I didn't do this manually but instead used the "Install Ubuntu alongside Windows 7" option during the installation. Now the partition that Ubuntu runs in has very little space and I am getting warning messages. I'm trying to use gparted 0.12.1-5 (via a live CD) to give Windows less space and give Ubuntu more. I've managed to remove 100GB from the Windows partition so I now have some unallocated space between Windows and Ubuntu. This is what it looks like inside Ubuntu (not using the live CD, since it won't let me mount a USB to save a screenshot): So first I take sda4 (extended?) and resize it to the left so it takes up all the unallocated space. Then I resize sda5 (ext4) as well so it takes up all the new space. However, when I hit apply, it fails on the first action (resizing sd4) with the error message can't have overlapping partitions. Any ideas as to why this happens? I also tried resizing sda4 by just a few MB so that it definitely didn't overlap anything, but I still got the same error message. To clarify, I am using gparted from the LiveCD, I just took the screenshot from Ubuntu. I couldn't attach the details file containing the error information from gparted because I can't mount a USB drive when I'm running from the LiveCD. I'm tried following the guide on the gparted website but it says Invalid argument or something like that. If the gparted details are needed, I may need some hints on how to solve the USB issue as well. :)

  • Book Review - Programming Windows Azure by Siriram Krishnan

    - by BuckWoody
    As part of my professional development, I’ve created a list of books to read throughout the year, starting in June of 2011. This a review of the first one, called Programming Windows Azure by Siriram Krishnan. You can find my entire list of books I’m reading for my career here: http://blogs.msdn.com/b/buckwoody/archive/2011/06/07/head-in-the-clouds-eyes-on-the-books.aspx  Why I Chose This Book: As part of my learning style, I try to read multiple books about a single subject. I’ve found that at least 3 books are necessary to get the right amount of information to me. This is a “technical” work, meaning that it deals with technology and not business, writing or other facets of my career. I’ll have a mix of all of those as I read along. I chose this work in addition to others I’ve read since it covers everything from an introduction to more advanced topics in a single book. It also has some practical examples of actually working with the product, particularly on storage. Although it’s dated, many examples normally translate. I also saw that it had pretty good reviews. What I learned: I learned a great deal about storage, and many useful code snippets. I do think that there could have been more of a focus on the application fabric - but of course that wasn’t as mature a feature when this book was written. I learned some great architecture examples, and in one section I learned more about encryption. In that example, however, I would rather have seen the examples go the other way - the book focused on moving data from on-premise to Azure storage in an encrypted fashion. Using the Application Fabric I would rather see sensitive data left in a hybrid fashion on premise, and connect to for the Azure application. Even so, the examples were very useful. If you’re looking for a good “starter” Azure book, this is a good choice. I also recommend the last chapter as a quick read for a DBA, or Database Administrator. It’s not very long, but useful. Note that the limits described are incorrect - which is one of the dangers of reading a book about any cloud offering. The services offered are updated so quickly that the information is in constant danger of being “stale”. Even so, I found this a useful book, which I believe will help me work with Azure better. Raw Notes: I take notes as I read, calling that process “reading with a pencil”. I find that when I do that I pay attention better, and record some things that I need to know later. I’ll take these notes, categorize them into a OneNote notebook that I synchronize in my Live.com account, and that way I can search them from anywhere. I can even read them on the web, since the Live.com has a OneNote program built in. Note that these are the raw notes, so they might not make a lot of sense out of context - I include them here so you can watch my though process. Programming Windows Azure by Siriram Krishnan: Learning about how to select applications suitable for Distributed Technology. Application Fabric gets the least attention; probably because it was newer at the time. Very clear (Chapter One) Good foundation Background and history, but not too much I normally arrange my descriptions differently, starting with the use-cases and moving to physicality, but this difference helps me. Interesting that I am reading this using Safari Books Online, which uses many of these concepts. Taught me some new aspects of a Hypervisor – very low-level information about the Azure Fabric (not to be confused with the Application Fabric feature) (Chapter Two) Good detail of what is included in the SDK. Even more is available now. CS = Cloud Service (Chapter 3) Place Storage info in the configuration file, since it can be streamed in-line with a running app. Ditto for logging, and keep separated configs for staging and testing. Easy-switch in and switch out.  (Chapter 4) There are two Runtime API’s, one of external and one for internal. Realizing how powerful this paradigm really is. Some places seem light, and to drop off but perhaps that’s best. Managing API is not charged, which is nice. I don’t often think about the price, until it comes to an actual deployment (Chapter 5) Csmanage is something I want to dig into deeper. API requires package moves to Blob storage first, so it needs a URL. Csmanage equivalent can be written in Unix scripting using openssl. Upgrades are possible, and you use the upgradeDomainCount attribute in the Service-Definition.csdef file  Always use a low-privileged account to test on the dev fabric, since Windows Azure runs in partial trust. Full trust is available, but can be dangerous and must be well-thought out. (Chapter 6) Learned how to run full CMD commands in a web window – not that you would ever do that, but it was an interesting view into those links. This leads to a discussion on hosting other runtimes (such as Java or PHP) in Windows Azure. I got an expanded view on this process, although this is where the book shows its age a little. Books can be a problem for Cloud Computing for this reason – things just change too quickly. Windows Azure storage is not eventually consistent – it is instantly consistent with multi-phase commit. Plumbing for this is internal, not required to code that. (Chapter 7) REST API makes the service interoperable, hybrid, and consistent across code architectures. Nicely done. Use affinity groups to keep data and code together. Side note: e-book readers need a common “notes” feature. There’s a decent quick description of REST in this chapter. Learned about CloudDrive code – PowerShell sample that mounts Blob storage as a local provider. Works against Dev fabric by default, can be switched to Account. Good treatment in the storage chapters on the differences between using Dev storage and Azure storage. These can be mitigated. No, blobs are not of any size or number. Not a good statement (Chapter 8) Blob storage is probably Azure’s closest play to Infrastructure as a Service (Iaas). Blob change operations must be authenticated, even when public. Chapters on storage are pretty in-depth. Queue Messages are base-64 encoded (Chapter 9) The visibility timeout ensures processing of message in a disconnected system. Order is not guaranteed for a message, so if you need that set an increasing number in the queue mechanism. While Queues are accessible via REST, they are not public and are secured by default. Interesting – the header for a queue request includes an estimated count. This can be useful to create more worker roles in a dynamic system. Each Entity (row) in the Azure Table service is atomic – all or nothing. (Chapter 10) An entity can have up to 255 Properties  Use “ID” for the class to indicate the key value, or use the [DataServiceKey] Attribute.  LINQ makes working with the Azure Table Service much easier, although Interop is certainly possible. Good description on the process of selecting the Partition and Row Key.  When checking for continuation tokens for pagination, include logic that falls out of the check in case you are at the last page.  On deleting a storage object, it is instantly unavailable, however a background process is dispatched to perform the physical deletion. So if you want to re-create a storage object with the same name, add retry logic into the code. Interesting approach to deleting an index entity without having to read it first – create a local entity with the same keys and apply it to the Azure system regardless of change-state.  Although the “Indexes” description is a little vague, it’s interesting to see a Folding and Stemming discussion a-la the Porter Stemming Algorithm. (Chapter 11)  Presents a better discussion of indexes (at least inverted indexes) later in the chapter. Great treatment for DBA’s in Chapter 11. We need to work on getting secondary indexes in Table storage. There is a limited form of transactions called “Entity Group Transactions” that, although they have conditions, makes a transactional system more possible. Concurrency also becomes an issue, but is handled well if you’re using Data Services in .NET. It watches the Etag and allows you to take action appropriately. I do not recommend using Azure as a location for secure backups. In fact, I would rather have seen the examples in (Chapter 12) go the other way, showing how data could be brought back to a local store as a DR or HA strategy. Good information on cryptography and so on even so. Chapter seems out of place, and should be combined with the Blob chapter.  (Chapter 13) on SQL Azure is dated, although the base concepts are OK.  Nice example of simple ADO.NET access to a SQL Azure (or any SQL Server Really) database.

  • Using Table-Valued Parameters With SQL Server Reporting Services

    - by Jesse
    In my last post I talked about using table-valued parameters to pass a list of integer values to a stored procedure without resorting to using comma-delimited strings and parsing out each value into a TABLE variable. In this post I’ll extend the “Customer Transaction Summary” report example to see how we might leverage this same stored procedure from within an SQL Server Reporting Services (SSRS) report. I’ve worked with SSRS off and on for the past several years and have generally found it to be a very useful tool for building nice-looking reports for end users quickly and easily. That said, I’ve been frustrated by SSRS from time to time when seemingly simple things are difficult to accomplish or simply not supported at all. I thought that using table-valued parameters from within a SSRS report would be simple, but unfortunately I was wrong. Customer Transaction Summary Example Let’s take the “Customer Transaction Summary” report example from the last post and try to plug that same stored procedure into an SSRS report. Our report will have three parameters: Start Date – beginning of the date range for which the report will summarize customer transactions End Date – end of the date range for which the report will summarize customer transactions Customer Ids – One or more customer Ids representing the customers that will be included in the report The simplest way to get started with this report will be to create a new dataset and point it at our Customer Transaction Summary report stored procedure (note that I’m using SSRS 2012 in the screenshots below, but there should be little to no difference with SSRS 2008): When you initially create this dataset the SSRS designer will try to invoke the stored procedure to determine what the parameters and output fields are for you automatically. As part of this process the following dialog pops-up: Obviously I can’t use this dialog to specify a value for the ‘@customerIds’ parameter since it is of the IntegerListTableType user-defined type that we created in the last post. Unfortunately this really throws the SSRS designer for a loop, and regardless of what combination of Data Type, Pass Null Value, or Parameter Value I used here, I kept getting this error dialog with the message, "Operand type clash: nvarchar is incompatible with IntegerListTableType". This error message makes some sense considering that the nvarchar type is indeed incompatible with the IntegerListTableType, but there’s little clue given as to how to remedy the situation. I don’t know for sure, but I think that behind-the-scenes the SSRS designer is trying to give the @customerIds parameter an nvarchar-typed SqlParameter which is causing the issue. When I first saw this error I figured that this might just be a limitation of the dataset designer and that I’d be able to work around the issue by manually defining the parameters. I know that there are some special steps that need to be taken when invoking a stored procedure with a table-valued parameter from ADO .NET, so I figured that I might be able to use some custom code embedded in the report  to create a SqlParameter instance with the needed properties and value to make this work, but the “Operand type clash" error message persisted. The Text Query Approach Just because we’re using a stored procedure to create the dataset for this report doesn’t mean that we can’t use the ‘Text’ Query Type option and construct an EXEC statement that will invoke the stored procedure. In order for this to work properly the EXEC statement will also need to declare and populate an IntegerListTableType variable to pass into the stored procedure. Before I go any further I want to make one point clear: this is a really ugly hack and it makes me cringe to do it. Simply put, I strongly feel that it should not be this difficult to use a table-valued parameter with SSRS. With that said, let’s take a look at what we’ll have to do to make this work. Manually Define Parameters First, we’ll need to manually define the parameters for report by right-clicking on the ‘Parameters’ folder in the ‘Report Data’ window. We’ll need to define the ‘@startDate’ and ‘@endDate’ as simple date parameters. We’ll also create a parameter called ‘@customerIds’ that will be a mutli-valued Integer parameter: In the ‘Available Values’ tab we’ll point this parameter at a simple dataset that just returns the CustomerId and CustomerName of each row in the Customers table of the database or manually define a handful of Customer Id values to make available when the report runs. Once we have these parameters properly defined we can take another crack at creating the dataset that will invoke the ‘rpt_CustomerTransactionSummary’ stored procedure. This time we’ll choose the ‘Text’ query type option and put the following into the ‘Query’ text area: 1: exec('declare @customerIdList IntegerListTableType ' + @customerIdInserts + 2: ' EXEC rpt_CustomerTransactionSummary 3: @startDate=''' + @startDate + ''', 4: @endDate='''+ @endDate + ''', 5: @customerIds=@customerIdList')   By using the ‘Text’ query type we can enter any arbitrary SQL that we we want to and then use parameters and string concatenation to inject pieces of that query at run time. It can be a bit tricky to parse this out at first glance, but from the SSRS designer’s point of view this query defines three parameters: @customerIdInserts – This will be a Text parameter that we use to define INSERT statements that will populate the @customerIdList variable that is being declared in the SQL. This parameter won’t actually ever get passed into the stored procedure. I’ll go into how this will work in a bit. @startDate – This is a simple date parameter that will get passed through directly into the @startDate parameter of the stored procedure on line 3. @endDate – This is another simple data parameter that will get passed through into the @endDate parameter of the stored procedure on line 4. At this point the dataset designer will be able to correctly parse the query and should even be able to detect the fields that the stored procedure will return without needing to specify any values for query when prompted to. Once the dataset has been correctly defined we’ll have a @customerIdInserts parameter listed in the ‘Parameters’ tab of the dataset designer. We need to define an expression for this parameter that will take the values selected by the user for the ‘@customerIds’ parameter that we defined earlier and convert them into INSERT statements that will populate the @customerIdList variable that we defined in our Text query. In order to do this we’ll need to add some custom code to our report using the ‘Report Properties’ dialog: Any custom code defined in the Report Properties dialog gets embedded into the .rdl of the report itself and (unfortunately) must be written in VB .NET. Note that you can also add references to custom .NET assemblies (which could be written in any language), but that’s outside the scope of this post so we’ll stick with the “quick and dirty” VB .NET approach for now. Here’s the VB .NET code (note that any embedded code that you add here must be defined in a static/shared function, though you can define as many functions as you want): 1: Public Shared Function BuildIntegerListInserts(ByVal variableName As String, ByVal paramValues As Object()) As String 2: Dim insertStatements As New System.Text.StringBuilder() 3: For Each paramValue As Object In paramValues 4: insertStatements.AppendLine(String.Format("INSERT {0} VALUES ({1})", variableName, paramValue)) 5: Next 6: Return insertStatements.ToString() 7: End Function   This method takes a variable name and an array of objects. We use an array of objects here because that is how SSRS will pass us the values that were selected by the user at run-time. The method uses a StringBuilder to construct INSERT statements that will insert each value from the object array into the provided variable name. Once this method has been defined in the custom code for the report we can go back into the dataset designer’s Parameters tab and update the expression for the ‘@customerIdInserts’ parameter by clicking on the button with the “function” symbol that appears to the right of the parameter value. We’ll set the expression to: 1: =Code.BuildIntegerListInserts("@customerIdList ", Parameters!customerIds.Value)   In order to invoke our custom code method we simply need to invoke “Code.<method name>” and pass in any needed parameters. The first parameter needs to match the name of the IntegerListTableType variable that we used in the EXEC statement of our query. The second parameter will come from the Value property of the ‘@customerIds’ parameter (this evaluates to an object array at run time). Finally, we’ll need to edit the properties of the ‘@customerIdInserts’ parameter on the report to mark it as a nullable internal parameter so that users aren’t prompted to provide a value for it when running the report. Limitations And Final Thoughts When I first started looking into the text query approach described above I wondered if there might be an upper limit to the size of the string that can be used to run a report. Obviously, the size of the actual query could increase pretty dramatically if you have a parameter that has a lot of potential values or you need to support several different table-valued parameters in the same query. I tested the example Customer Transaction Summary report with 1000 selected customers without any issue, but your mileage may vary depending on how much data you might need to pass into your query. If you think that the text query hack is a lot of work just to use a table-valued parameter, I agree! I think that it should be a lot easier than this to use a table-valued parameter from within SSRS, but so far I haven’t found a better way. It might be possible to create some custom .NET code that could build the EXEC statement for a given set of parameters automatically, but exploring that will have to wait for another post. For now, unless there’s a really compelling reason or requirement to use table-valued parameters from SSRS reports I would probably stick with the tried and true “join-multi-valued-parameter-to-CSV-and-split-in-the-query” approach for using mutli-valued parameters in a stored procedure.

  • Does HTML 5 &ldquo;Rich vs. Reach&rdquo; a False Choice?

    - by andrewbrust
    The competition between the Web and proprietary rich platforms, including Windows, Mac OS, iPhone/iPad, Adobe’s Flash/AIR and Microsoft’s Silverlight, is not new. But with the emergence of HTML 5 and imminent support for it in the next release of the major Web browsers, the battle is heating up. And with the announcements made Wednesday at Google's I/O conference, it's getting kicked up yet another notch. The impact of this platform battle on companies in the media and advertising world, and the developers who serve them, is significant. The most prominent question is whether video and rich media online will shift towards pure HTML and away from plug-ins like Flash and Silverlight. In fact, certain features in HTML 5 make it suitable for development for line of business applications as well, further threatening those plug-in technologies. So what's the deal? Is this real or hype? To answer that question, I've done my own research into HTML 5's features and talked to several media-focused, New York area developers to get their opinions. I present my findings to you in this post. Before bearing down into HTML 5 specifics and practitioners’ quotes, let's set the context. To understand what HTML 5 can do, take a look at this video of Sports Illustrated’s HTML 5 prototype. This should start to get you bought into the idea that HTML 5 could be a game-changer. Next, if you happen to have installed the beta version of Google's Chrome 5 browser, take a look at the page linked to below, and in that page, click on any of the game thumbnails to see what's possible, without a plug-in, in this brave new world. (Note, although the instructions for each game tell you to press the A key to start, press the Z key instead.). Here's the link: http://www.kesiev.com/akihabara As an adjunct to what's enabled by HTML 5, consider the various transforms that are part of CSS 3. If you're running Safari as your browser, the following link will showcase this live; if not, you'll see a bitmap that will give you an idea of what's possible: http://webkit.org/blog/386/3d-transforms Are you starting to get the picture (literally)? What has up until now required browser plug-ins and other patches to HTML, most typically Flash, will soon be renderable, natively, in all major browsers. Moreover, it's looking likely that developers will be able to deliver such content and experiences in these browsers using one base of markup and script code (using straight JavaScript and/or jQuery), without resorting to browser-specific code and workarounds. If you're skeptical of this, I wouldn't blame you, especially with respect to Microsoft's Internet Explorer. However, i can tell you with confidence that even Microsoft is dedicated to full-on HTML 5 support in version 9 of that browser, which is currently under development. So what’s new in HTML 5, specifically, that makes sites like this possible?  The specification documents go into deep detail, and there’s no sense in rehashing them here, but a summary is probably in order.   Here is a non-authoritative, but useful, list of the major new feature areas in HTML 5: 2D drawing capabilities and 3D transforms. 2D drawing instructions can be embedded statically into a Web page; application interactivity and animation can be achieved through script.  As mentioned above, 3D transforms are technically part of version 3 of the CSS (Cascading Style Sheets) spec, rather than HTML 5, but they can nonetheless be thought of as part of the bundle.  They allow for rendering of 3D images and animations that, together with 2D drawing, make HTML-based games much more feasible than they are presently, as the links above demonstrate. Embedded audio and video. A media player can appear directly in a rendered Web page, using HTML markup and no plug-ins. Alternately, player controls can be hidden and the content can play automatically. Major enhancements to form-based input. This includes such things as specification of required fields, embedding of text “hints” into a control, limiting valid input on a field to dates, email addresses or a list of values.  There’s more to this, but the gist is that line-of-business applications, with complicated input and data validation, are supported directly Offline caching, local storage and client-side SQL database. These facilities allow Web applications to function more like native apps, even if no internet connection is available. User-defined data. Data (or metadata – data about data) can easily be embedded statically and/or retrieved and updated with Javascript code. This avoids having to embed that data in a separate file, or within script code. Taken together, these features position HTML to compete with, and perhaps overtake, Adobe’s Flash/AIR (and Microsoft’s Silverlight) as a viable Web platform for media, RIAs (rich internet applications – apps that function more like desktop software than Web sites) and interactive Web content, including games. What do players in the media world think about this?  From the embedded video above, we know what Sports Illustrated (and, therefore, Time Warner) think.  Hulu, the major Internet site for broadcast TV content, is on record as saying HTML5 video does not pass muster with them, at least not yet.  YouTube, on the other hand, already has an experimental HTML 5-based version of their site.  TechCrunch has reported that NetFlix is flirting with HTML 5 too, especially as it pertains to embedded browsers in TV-based devices.  And the New York Times’ Web site now embeds some video clips without resorting to Flash.  They have to – otherwise iPhone, iPod Touch and iPad users couldn’t see them in the Mobile Safari browser. What do media-focused developers think about all this?  I talked to several to get their opinions. Michael Pinto is CEO and Founder of Very Memorable Design whose primary focus has been to help marketing directors get traction online.  The firm’s client roster includes the likes Time, Inc., Scholastic and PBS.  Pinto predicts that “More and more microsites that were done entirely in Flash will be done more and more using jQuery. I can also see slideshows and video now being done without Flash. However if you needed to create a game or highly interactive activity Flash would still be the way to go for the web.” A dissenting view comes from Jesse Erlbaum, CEO of The Erlbaum Group, LLC, which serves numerous clients in the magazine publishing sector.  When I asked Erlbaum whether he thought HTML 5 and jQuery/JavaScript would steal significant market share from Flash, he responded “Not at all!  In particular, not for media and advertising customers!  These sectors are not generally in the business of making highly functional applications, which is the one place where HTML5/jQuery/etc really shines.” Ironically, Pinto’s firm is a heavy user of Flash for its projects and Erlbaum’s develops atop the “LAMP” (Linux, Apache, MySQL and PHP/Perl) stack.  For whatever reason, each firm seems to see the other’s toolset as a more viable choice.  But both agree that the developer tool story around HTML 5 is deficient.  Pinto explains “What’s lost with [HTML 5 and Javascript] techniques is that there isn’t a single widely favored easy-to-use tool of choice for authoring. So with Flash you can get up and running right away and not worry about what is different from one browser to the next.“  Erlbaum agrees, saying: “HTML5/Javascript lacks a sophisticated integrated development environment (IDE) which is an essential part of Flash.  If what someone is trying to make is primarily animation, it's a waste of time…to do this in Javascript.  It can be done much more easily in Flash, and with greater cross-browser compatibility and consistency due to the ubiquity of Flash.” Adobe (maker of Flash since its 2005 acquisition of Macromedia) likely agrees.  And for better or worse, they’ve decided to address this shortcoming of HTML 5, even at risk of diminishing their Flash platfrom. Yesterday Adobe announced that their hugely popular Deamweaver Web design authoring tool would directly support HTML 5 and CSS 3 development.  In fact, the Adobe Dreamweaver CS5 HTML5 Pack is downloadable now from Adobe Labs. Maybe Adobe is bowing to pressure from ardent Web professionals like Scott Kellum, Lead Designer at Channel V Media,  a digital and offline branding firm, serving the media and marketing sectors, among others.  Kellum told me that HTML 5 “…will definitely move people away from Flash. It has many of the same functionalities with faster load times and better accessibility. HTML5 will help Flash as well: with the new caching methods you can now even run Flash apps offline.” Although all three Web developers I interviewed would agree that Flash is still required for more sophisticated applications, Kellum seems to have put his finger on why HTML 5 may nonetheless dominate.  In his view, much of the Web development out there has little need for high-end capabilities: “Most people want to add a little punch to a navigation bar or some video and now you can get the biggest bang for your buck with HTML5, CSS3 and Javascript.” I’ve already mentioned that Google’s ongoing I/O conference, at the Moscone West center in San Francisco, is driving the HTML 5 news cycle, big time.  And Google made many announcements of their own, including the open sourcing of their VP8 video codec, new enterprise-oriented capabilities for its App Engine cloud offering, and the creation of the Chrome Web Store, which the company says will make it easier to find and “install” Web applications, in a fashion similar to  the way users procure native apps on various mobile platforms. HTML 5 looks to be disruptive, especially to the media world.  And even if the technology ends up disappointing, the chatter around it alone is causing big changes in the technology world.  If the richness it promises delivers, then magazine publishers and non-text digital advertisers may indeed have a platform for creating compelling content that loads quickly, is standards-based and will render identically in (the newest versions of) all major Web browsers.  Can this development in the digital arena save the titans of the print world?  I can’t predict, but it’s going to be fun to watch, and the competitive innovation from all players in both industries will likely be immense.
