  • Tips To Manage An Effectively Come Back To Work After A Long Vacation

    - by Gopinath
    Vacations are very relaxing – no need to reply to endless mails, no marathon meeting or conference calls. It’s all about fun during the vacation. The troubles begin as you near the end of vacation and plans to think about getting back to work. Once we are back to work after a long vacation there will be many things to worry – a pile of snail mails, hundreds of unread emails,  a flood of phone calls to answer and a stream of scheduled meetings. How to handle all the backlog and catch up quickly with the inflow of work? Here is a management tip from Harvard Business Review blog to get back to work the right way after a long vacation Block off your morning. Make sure you don’t have any meetings scheduled or big projects due. Then before you open your inbox, pause and think about your work priorities. As you make your way through emails and voicemails, focus on returning the messages that are connected to what matters most. Defer or delegate things that aren’t top priority. And remember it will probably take more than one day to get caught up, so be easy on yourself. Hope these tips lets you plan a right comeback to work after your vacation. cc Image credit: flickr/dfwcre8tive This article titled,Tips To Manage An Effectively Come Back To Work After A Long Vacation, was originally published at Tech Dreams.

  • Visual Studio 2010 Hosting :: Connect to MySQL Database from Visual Studio VS2010

    - by mbridge
    So, in order to connect to a MySql database from VS2010 you need to 1. download the latest version of the MySql Connector/NET from http://www.mysql.com/downloads/connector/net/ 2. install the connector (if you have an older version you need to remove it from Control Panel -> Add / Remove Programs) 3. open Visual Studio 2010 4. open Server Explorer Window (View -> Server Explorer) 5. use Connect to Database button 6. in the Choose Data Source windows select MySql Database and press Continue 7. in the Add Connection window - set server name: 127.0.0.1 or localhost for MySql server running on local machine or an IP address for a remote server - username and password - if the the above data is correct and the connection can be made, you have the possibility to select the database If you want to connect to a MySql database from a C# application (Windows or Web) you can use the next sequence: //define the connection reference and initialize it MySql.Data.MySqlClient.MySqlConnection msqlConnection = null; msqlConnection = new MySql.Data.MySqlClient.MySqlConnection(“server=localhost;user id=UserName;Password=UserPassword;database=DatabaseName;persist security info=False”);     //define the command reference MySql.Data.MySqlClient.MySqlCommand msqlCommand = new MySql.Data.MySqlClient.MySqlCommand();     //define the connection used by the command object msqlCommand.Connection = this.msqlConnection;     //define the command text msqlCommand.CommandText = "SELECT * FROM TestTable;"; try {     //open the connection     this.msqlConnection.Open();     //use a DataReader to process each record     MySql.Data.MySqlClient.MySqlDataReader msqlReader = msqlCommand.ExecuteReader();     while (msqlReader.Read())     {         //do something with each record     } } catch (Exception er) {     //do something with the exception } finally {     //always close the connection     this.msqlConnection.Close(); }.

  • Handling EJB/JPA exceptions in a “beautiful” way

    - by Rodrigues, Raphael
    In order to handle JPA exceptions, there are some ways already detailed in lots of blogs. Here, I intend to show one of them, which I consider kind of “beauty”. My use case has a unique constraint, when the User try to create a duplicate value in database. The JPA throws a java.sql.SQLIntegrityConstraintViolationException, and I have to catch it and replace the message. In fact, ADF Business Components framework already has a beautiful solution for this very well documented here . However, for EJB/JPA there's no similar approach. In my case, what I had to do was: 1. Create a custom Error Handler Class in DataBindings file; a. Here is how you accomplish it. 2. Override the reportException method and check if the type of exception exists on property file a. If yes, I change the message and rethrows the exception b. If not, go on the execution The main goal of this approach is whether a new or unhandled Exception was raised, the job is, only create a single entry in bundle property file. Here are pictures step by step: 1. CustomExceptionHandler.java 2. Databindings.cpx 3. Bundle file 4. jspx: 5. Stacktrace: Give your opinion, what did you think about that?

  • The Low Down Dirty Azure Blues

    - by SGWellens
    Remember the SETI screen savers that used to be on everyone's computer? As far I as know, it was the first bona-fide use of "Cloud" computing…albeit an ad hoc cloud. I still think it was a brilliant leveraging of computing power. My interest in clouds was re-piqued when I went to a technical seminar at the local .Net User Group. The speaker was Mike Benkovitch and he expounded magnificently on the virtues of the Azure platform. Mike always does a good job. One killer reason he gave for cloud computing is instant scalability. Not applicable for most applications, but it is there if needed. I have a bunch of files stored on Microsoft's SkyDrive platform which is cloud storage. It is painfully slow. Accessing a file means going through layers and layers of software, redirections and security. Am I complaining? Hell no! It's free! So my opinions of Cloud Computing are both skeptical and appreciative. What intrigued me at the seminar, in addition to its other features, is that Azure can serve as a web hosting platform. I have a client with an Asp.Net web site I developed who is not happy with the performance of their current hosting service. I checked the cost of Azure and since the site has low bandwidth/space requirements the cost would be competitive with the existing host provider: Azure Pricing Calculator. And, Azure has a three month free trial. Perfect! I could try moving the website and see how it works for free. I went through the signup process. Everything was proceeding fine until I went to the MS SQL database management screen. A popup window informed me that I needed to install Silverlight on my machine. Silverlight? No thanks. Buh-Bye. I half-heartedly found the Azure support button and logged a ticket telling them I didn't want Silverlight on my machine. Within 4 to 6 hours (and a myriad (5) of automated support emails) they sent me a link to a database management page that did not require Silverlight. Thanks! I was able to create a database immediately. One really nice feature was that after creating the database, I was given a list of connection strings. I went to the current host provider, made a backup of the database and saved it to my machine. I attached to the remote database using SQL Server Studio 2012 and looked for the Restore menu item. It was missing. So I tried using the SQL command: RESTORE DATABASE MyDatabase FROM DISK ='C:\temp\MyBackup.bak' Msg 40510, Level 16, State 1, Line 1 Statement 'RESTORE DATABASE' is not supported in this version of SQL Server. Are you kidding me? Why on earth…? This can't be happening! I opened both the source database and destination database in SQL Management Studio. I right clicked the source database, selected "Tasks" and noticed a menu selection called "Deploy Database to SQL Azure" Are you kidding me? Could it be? Oh yes, it be! There was a small problem because the database already existed on the Azure machine, I deployed to a new name, deleted the existing database and renamed the deployed database to what I needed. It was ridiculously easy. Being able to attach SQL Management Studio to remote databases is an awesome but scary feature. You can limit the IP addresses that can access the database which enhances security but when you give people, any people, me included, that much power, one errant mouse click could bring a live system down. My Advice: Tread softly and carry a large backup thumb-drive. Then I created a web site, the URL it returned look something like this: http://MyWebSite.azurewebsites.net/ Azure supports FTP, but I couldn't figure out the settings until I downloaded the publishing profile. It was an XML file that contained the needed information. I still couldn't connect with my FTP client (FileZilla). After about an hour of messing around, I deleted the port number from the FileZilla setup page….and voila, I was in like Flynn.   There are other options of deploying directly from Visual Studio, TFS, etc. but I do not like integrated tools that do things without my asking: It's usually hard to figure out what they did and how to undo it. I uploaded the aspx , cs , webconfig, etc. files. Bu it didn't run. The site I ported was in .NET 3.5. The Azure website configuration page gave me a choice between .NET 2.0 and 4.0. So, I switched to Visual Studio 2010, chose .NET 4.0 and upgraded the site. Of course I have the original version completely backed up and stored in a granite cave beneath the Nevada desert. And I have a backup CD under my pillow. The site uses ReportViewer to generate PDF documents. Of course it was the wrong version. I removed the old references to version 9 and added new references to version 10 (*see note below). Since the DLLs were not on the Azure Server, I uploaded them to the bin directory, crossed my fingers, burned some incense and gave it a try. After some fiddling around it ran. I don't know if I did anything particular to make it work or it just needed time to sort things out. However, one critical feature didn't work: ReportViewer could not programmatically generate PDF documents. I was getting this exception: "An error occurred during local report processing. Parameter is not valid." Rats. I did some searching and found other people were having the same problem, so I added a post saying I was having the same problem: http://social.msdn.microsoft.com/Forums/en-US/windowsazurewebsitespreview/thread/b4a6eb43-0013-435f-9d11-00ee26a8d017 Currently they are looking into this problem and I am waiting for the results. Hence I had the time to write this BLOG entry. How lucky you are. This was the last message I got from the Microsoft person: Hi Steve, Windows Azure Web Sites is a multi-tenant environment. For security issue, we limited some API calls. Unfortunately, some GDI APIS required by the PDF converting function are in this list. We have noticed this issue, and still investigation the best way to go. At this moment, there is no news to share. Sorry about this. Will keep you posted. If I had to guess, I would say they are concerned with people uploading images and doing intensive graphics programming which would hog CPU time.  But that is just a guess. Another problem. While trying to resolve the ReportViewer problem, I tried to write a file to the PDF directory to see if there was a permissions problem with some test code: String MyPath = MapPath(@"~\PDFs\Test.txt"); File.WriteAllText(MyPath, "Hello Azure");     I got this message: Access to the path <my path> is denied. After some research, I understood that since Azure is a cloud based platform, it can't allow web applications to save files to local directories. The application could be moved or replicated as scaling occurs and trying to manage local files would be problematic to say the least. There are other options: Use the Azure APIs to get a path. That way the location of the storage is separated from the application. However, the web site is then tied Azure and can't be moved to another hosting platform. Use the ApplicationData folder (not recommended). Write to BLOB storage. Or, I could try and stream the PDF output directly to the email and not save a file. I'm not going to work on a final solution until the ReportViewer is fixed. I am just sharing some of the things you need to be aware of if you decide to use Azure. I got this information from here. (Note the author of the BLOG added a comment saying he has updated his entry). Is my memory faulty? While getting this BLOG ready, I tried to write the test file again. And it worked. My memory is incorrect, or much more likely, something changed on the server…perhaps while they are trying to get ReportViewer to work. (Anyway, that's my story and I'm sticking to it). *Note: Since Visual Studio 2010 Express doesn't include a Report Editor, I downloaded and installed SQL Server Report Builder 2.0. It is a standalone Report Editor to replace the one not in Visual Studio 2010 Express. I hope someone finds this useful. Steve Wellens CodeProject

  • Creating a Dynamic DataRow for easier DataRow Syntax

    - by Rick Strahl
    I've been thrown back into an older project that uses DataSets and DataRows as their entity storage model. I have several applications internally that I still maintain that run just fine (and I sometimes wonder if this wasn't easier than all this ORM crap we deal with with 'newer' improved technology today - but I disgress) but use this older code. For the most part DataSets/DataTables/DataRows are abstracted away in a pseudo entity model, but in some situations like queries DataTables and DataRows are still surfaced to the business layer. Here's an example. Here's a business object method that runs dynamic query and the code ends up looping over the result set using the ugly DataRow Array syntax:public int UpdateAllSafeTitles() { int result = this.Execute("select pk, title, safetitle from " + Tablename + " where EntryType=1", "TPks"); if (result < 0) return result; result = 0; foreach (DataRow row in this.DataSet.Tables["TPks"].Rows) { string title = row["title"] as string; string safeTitle = row["safeTitle"] as string; int pk = (int)row["pk"]; string newSafeTitle = this.GetSafeTitle(title); if (newSafeTitle != safeTitle) { this.ExecuteNonQuery("update " + this.Tablename + " set safeTitle=@safeTitle where pk=@pk", this.CreateParameter("@safeTitle",newSafeTitle), this.CreateParameter("@pk",pk) ); result++; } } return result; } The problem with looping over DataRow objecs is two fold: The array syntax is tedious to type and not real clear to look at, and explicit casting is required in order to do anything useful with the values. I've highlighted the place where this matters. Using the DynamicDataRow class I'll show in a minute this code can be changed to look like this:public int UpdateAllSafeTitles() { int result = this.Execute("select pk, title, safetitle from " + Tablename + " where EntryType=1", "TPks"); if (result < 0) return result; result = 0; foreach (DataRow row in this.DataSet.Tables["TPks"].Rows) { dynamic entry = new DynamicDataRow(row); string newSafeTitle = this.GetSafeTitle(entry.title); if (newSafeTitle != entry.safeTitle) { this.ExecuteNonQuery("update " + this.Tablename + " set safeTitle=@safeTitle where pk=@pk", this.CreateParameter("@safeTitle",newSafeTitle), this.CreateParameter("@pk",entry.pk) ); result++; } } return result; } The code looks much a bit more natural and describes what's happening a little nicer as well. Well, using the new dynamic features in .NET it's actually quite easy to implement the DynamicDataRow class. Creating your own custom Dynamic Objects .NET 4.0 introduced the Dynamic Language Runtime (DLR) and opened up a whole bunch of new capabilities for .NET applications. The dynamic type is an easy way to avoid Reflection and directly access members of 'dynamic' or 'late bound' objects at runtime. There's a lot of very subtle but extremely useful stuff that dynamic does (especially for COM Interop scenearios) but in its simplest form it often allows you to do away with manual Reflection at runtime. In addition you can create DynamicObject implementations that can perform  custom interception of member accesses and so allow you to provide more natural access to more complex or awkward data structures like the DataRow that I use as an example here. Bascially you can subclass DynamicObject and then implement a few methods (TryGetMember, TrySetMember, TryInvokeMember) to provide the ability to return dynamic results from just about any data structure using simple property/method access. In the code above, I created a custom DynamicDataRow class which inherits from DynamicObject and implements only TryGetMember and TrySetMember. Here's what simple class looks like:/// <summary> /// This class provides an easy way to turn a DataRow /// into a Dynamic object that supports direct property /// access to the DataRow fields. /// /// The class also automatically fixes up DbNull values /// (null into .NET and DbNUll to DataRow) /// </summary> public class DynamicDataRow : DynamicObject { /// <summary> /// Instance of object passed in /// </summary> DataRow DataRow; /// <summary> /// Pass in a DataRow to work off /// </summary> /// <param name="instance"></param> public DynamicDataRow(DataRow dataRow) { DataRow = dataRow; } /// <summary> /// Returns a value from a DataRow items array. /// If the field doesn't exist null is returned. /// DbNull values are turned into .NET nulls. /// /// </summary> /// <param name="binder"></param> /// <param name="result"></param> /// <returns></returns> public override bool TryGetMember(GetMemberBinder binder, out object result) { result = null; try { result = DataRow[binder.Name]; if (result == DBNull.Value) result = null; return true; } catch { } result = null; return false; } /// <summary> /// Property setter implementation tries to retrieve value from instance /// first then into this object /// </summary> /// <param name="binder"></param> /// <param name="value"></param> /// <returns></returns> public override bool TrySetMember(SetMemberBinder binder, object value) { try { if (value == null) value = DBNull.Value; DataRow[binder.Name] = value; return true; } catch {} return false; } } To demonstrate the basic features here's a short test: [TestMethod] [ExpectedException(typeof(RuntimeBinderException))] public void BasicDataRowTests() { DataTable table = new DataTable("table"); table.Columns.Add( new DataColumn() { ColumnName = "Name", DataType=typeof(string) }); table.Columns.Add( new DataColumn() { ColumnName = "Entered", DataType=typeof(DateTime) }); table.Columns.Add(new DataColumn() { ColumnName = "NullValue", DataType = typeof(string) }); DataRow row = table.NewRow(); DateTime now = DateTime.Now; row["Name"] = "Rick"; row["Entered"] = now; row["NullValue"] = null; // converted in DbNull dynamic drow = new DynamicDataRow(row); string name = drow.Name; DateTime entered = drow.Entered; string nulled = drow.NullValue; Assert.AreEqual(name, "Rick"); Assert.AreEqual(entered,now); Assert.IsNull(nulled); // this should throw a RuntimeBinderException Assert.AreEqual(entered,drow.enteredd); } The DynamicDataRow requires a custom constructor that accepts a single parameter that sets the DataRow. Once that's done you can access property values that match the field names. Note that types are automatically converted - no type casting is needed in the code you write. The class also automatically converts DbNulls to regular nulls and vice versa which is something that makes it much easier to deal with data returned from a database. What's cool here isn't so much the functionality - even if I'd prefer to leave DataRow behind ASAP -  but the fact that we can create a dynamic type that uses a DataRow as it's 'DataSource' to serve member values. It's pretty useful feature if you think about it, especially given how little code it takes to implement. By implementing these two simple methods we get to provide two features I was complaining about at the beginning that are missing from the DataRow: Direct Property Syntax Automatic Type Casting so no explicit casts are required Caveats As cool and easy as this functionality is, it's important to understand that it doesn't come for free. The dynamic features in .NET are - well - dynamic. Which means they are essentially evaluated at runtime (late bound). Rather than static typing where everything is compiled and linked by the compiler/linker, member invokations are looked up at runtime and essentially call into your custom code. There's some overhead in this. Direct invocations - the original code I showed - is going to be faster than the equivalent dynamic code. However, in the above code the difference of running the dynamic code and the original data access code was very minor. The loop running over 1500 result records took on average 13ms with the original code and 14ms with the dynamic code. Not exactly a serious performance bottleneck. One thing to remember is that Microsoft optimized the DLR code significantly so that repeated calls to the same operations are routed very efficiently which actually makes for very fast evaluation. The bottom line for performance with dynamic code is: Make sure you test and profile your code if you think that there might be a performance issue. However, in my experience with dynamic types so far performance is pretty good for repeated operations (ie. in loops). While usually a little slower the perf hit is a lot less typically than equivalent Reflection work. Although the code in the second example looks like standard object syntax, dynamic is not static code. It's evaluated at runtime and so there's no type recognition until runtime. This means no Intellisense at development time, and any invalid references that call into 'properties' (ie. fields in the DataRow) that don't exist still cause runtime errors. So in the case of the data row you still get a runtime error if you mistype a column name:// this should throw a RuntimeBinderException Assert.AreEqual(entered,drow.enteredd); Dynamic - Lots of uses The arrival of Dynamic types in .NET has been met with mixed emotions. Die hard .NET developers decry dynamic types as an abomination to the language. After all what dynamic accomplishes goes against all that a static language is supposed to provide. On the other hand there are clearly scenarios when dynamic can make life much easier (COM Interop being one place). Think of the possibilities. What other data structures would you like to expose to a simple property interface rather than some sort of collection or dictionary? And beyond what I showed here you can also implement 'Method missing' behavior on objects with InvokeMember which essentially allows you to create dynamic methods. It's all very flexible and maybe just as important: It's easy to do. There's a lot of power hidden in this seemingly simple interface.

  • SQLAuthority News – 2 Security Updates for SQL Server 2000 SP 4 Users

    - by pinaldave
    If you are using SQL Server 2000 still today my very first recommendation to you is to upgrade to SQL Server 2012. SQL Server 2000 is now 12 years old product and since then many new enhancements as well features which are relevant to current growth and progress in Informational Industry. Now is the time to catch up with the latest trends. Here is one more point for you to notice if this helps you consider to upgrade to the latest version. One can’t upgrade directly from SQL Server 2000 to SQL Server 2012. You need to first upgrade to either SQL Server 2005/2008/R2 and then further plan to upgrade to SQL Server 2012. There is no direct upgrade path for SQL Server 2000 to SQL Server 2012. I strongly believe this is the time to upgrade to the latest version. Well, also there is a rule that to let something continue if it is not broken and working fine. If you are following that rule and still using SQL Server 2000 I strongly suggest that you upgrade your SQL Server 2000 SP4 and update it with latest Security updates. Here are two important SQL Server Security Updates. Security Update for SQL Server 2000 Service Pack 4 (KB983811) Security Update for SQL Server 2000 Service Pack 4 (KB983812) As we are talking about SQL Server 2000 let me ask you a quick question – how many of you are still using SQL Server 2000 or earlier version in a production system on at least one server?

  • Parsing scripts that use curly braces

    - by Keikoku
    To get an idea of what I'm doing, I am writing a python parser that will parse directx .x text files. The problem I have deals with how the files are formatted. Although I'm writing it in python, I'm looking for general algorithms for dealing with this sort of parsing. .x files define data using templates. The format of a template is template_name { [some_data] } The goal I have is to parse the file line-by-line and whenever I come across a template, I will deal with it accordingly. My initial approach was to check if a line contains an opening or closing brace. If it's an open brace, then I will check what the template name is. Now the catch here is that the open brace doesn't have to occur on the same line as the template name. It could just as well be template_name { [some_data] } So if I were to use my "open brace exists" criteria, it won't work for any files that use the latter format. A lot of languages also use curly braces (though I'm not sure when people would be parsing the scripts themselves), so I was wondering if anyone knows how to accurately get the template name (or in some other languages, it could just as well be a function name, though there aren't any keywords to look for)

  • BUILD apps that use C++ AMP

    - by Daniel Moth
    If you are a developer on the Microsoft platform, you are hopefully attending (live or virtually) the sessions of the BUILD conference, aka //build/ in Anaheim, CA. The conference sold out not long after it opened registration, and it achieved that without sharing *any* session details nor a meaningful agenda up until after the keynote today – impressive! I am speaking at BUILD and hope you'll catch my talk at 9am on Friday (the last day of the conference) at Marriott Elite 2 Ballroom. Session details follow. 802 - Taming GPU compute with C++ AMP Developers today inject parallelism into their compute-intensive applications in order to take advantage of multi-core CPU hardware. Beyond CPUs, however, compute accelerators such as general-purpose GPUs can provide orders of magnitude speed-ups for data parallel algorithms. How can you as a C++ developer fully utilize this heterogeneous hardware from your Visual Studio environment?  How can you benefit from this tremendous performance boost in your Visual C++ solutions without sacrificing developer productivity?  The answers will be presented in this session about C++ Accelerated Massive Parallelism. I'll be covering a lot of the material I've been recently blogging about on my blog that you are reading, which I have also indexed over on our team blog under the title: "C++ AMP in a nutshell". Comments about this post by Daniel Moth welcome at the original blog.

  • Lightning talk: Coderetreat

    - by Michael Williamson
    In the spirit of trying to encourage more deliberate practice amongst coders in Red Gate, Lauri Pesonen had the idea of running a coderetreat in Red Gate. Lauri and I ran the first one a few weeks ago: given that neither of us hadn’t even been to a coderetreat before, let alone run one, I think it turned out quite well. The participants gave positive feedback, saying that they enjoyed the day, wrote some thought-provoking code and would do it again. Sam Blackburn was one of the attendees, and gave a lightning talk to the other developers in one of our regular lightning talk sessions: In case you can’t watch the video, I’ve transcribed the talk below, although I’d recommend watching the video if you can — I didn’t have much time to do the transcribing! So, what is a coderetreat? So it’s not just something in Red Gate, there’s a website and everything, although it’s not a very big website. It calls itself a community network. The basic ideas behind coderetreat are: you’ve got one day, and you split it into one hour sections. You spend three quarters of that coding, and do a little retrospective at the end. You’re supposed to start fresh each, we were told to delete our code after every session. We were in pairs, swapping after each session, and we did the same task every time. In fact, Conway’s Game of Life is the only task mentioned anywhere that I find for coderetreat. So I don’t know what we’ll do next time, or if we’re meant to do the same thing again. There are some guiding principles which felt to us like restrictions, that you have to code in crazy ways to encourage better code. Final thing is that it’s supposed to be free for outsiders to join. It’s meant to be a kind of networking thing, where you link up with people from other companies. We had a pilot day with Michael and Lauri. Since it was basically the first time any of us had done anything like this, everybody was from Red Gate. We didn’t chat to anybody else for the initial one. The task was Conway’s Game of Life, which most of you have probably heard of it, all but one of us knew about it when did the coderetreat. I won’t got into the details of what it is, but it felt like the right size of task, basically one or two groups actually produced something working by the end of the day, and of course that doesn’t mean it’s necessarily a day’s work to produce that because we were starting again every hour. The task really drives you more than trying to create good code, I found. It was really tempting to try and get it working rather than stick to the rules. But it’s really good to stop and try again because there are so many what-ifs when you’ve finished writing something, “what if I’d done it this way?”. You can answer all those questions at a coderetreat because it’s not about getting a product out the door, it’s about learning and playing with ideas. So we had all these different practices we were trying. I’ll try and go through most of these. Single responsibility is this idea that everything should do just one thing. It was the very first session, we were still trying to figure out how do you go about the Game of Life? So by the end of forty-five minutes hadn’t produced very much for that first session. We were still thinking, “Do we start with a board, how do we represent all these squares? It can be infinitely big, help, this is getting really difficult!”. So, most of us didn’t really get anywhere on the first one. Although it was interesting that some people started with the board, one group started with the FateDecider class that decides whether things live or die. A sort of god class, but in a good way. They managed to implement all of the rules without even defining how the squares were arranged or anything like that. Another thing we tried was TDD (test-driven development). I’m sure most of you know what TDD is: Watch a test, watch it fail for the right reason Write code to pass the test, watch it pass Refactor, check the test still passes Repeat! It basically worked, we were able to produce code, but we often found the tests defined the direction that code went, which is obviously the idea of TDD. But you tend to find that by the time you’ve even written your first assertion, which is supposed to be the very first thing you write, because you write your tests backwards from the assertions back to the initial conditions, you’ve already constrained the logic of the code in some way by the time you’ve done that. You then get to this situation of, “Well, we actually want to go in a slightly different direction. Can we do this?”. Can we write tests that don’t constrain the architecture? Wrapping up all primitives: it’s kind of turtles all the way down. We had a Size, which has a Width and Height, which both derive from Dimension. You’ve got pages of code before you’ve even done anything. No getters and setters (use tell don’t ask instead): mocks and stubs for tests are required if you want to assert that your results are what you think they should be. You can’t just check the internal state of the code. And people found that really challenging and it made them think in a different way which I think is really good. Not having mutable state: that was kind of confusing because we weren’t quite sure what fitted within that rule and what didn’t, and I think we were trying too hard to follow the rule rather than the guideline. No if-statements: supposed to use polymorphism instead, but polymorphism still requires a factory with conditional behaviour. We did something really crazy to get around this: public T If(bool condition, Func<T> left, Func<T> right) { var dict = new Dictionary<bool, Func<T>> {{true, left}, {false, right}}; return dict[condition].Invoke(); } That is not really polymorphism, is it? For-loops: you can always replace a for-loop with recursion, but it doesn’t tend to make it any more readable unless it’s the kind of task that really lends itself to that. So it was interesting, it was good practice, but it wouldn’t make it easier it’s the kind of tree-structure algorithm where that would help. Having a limit on the number of levels of indentation: again, I think it does produce very nice, clean code, but it wasn’t actually a challenge because you just extract methods. That’s quite a useful thing because you can apply that to real code and say, “Okay, should this method really be going crazy like this?” No talking: we hated that. It’s like there’s two of you at a computer, and one of you is doing the typing, what does the other guy do if they’re not allowed to talk. The answer is TDD ping-pong – one person writes the tests, and then the other person writes the code to pass the test. And that creates communication without actually having to have discussion about things which is kind of cool. No code comments: just makes no difference to anything. It’s a forty-five minute exercise, so what are you going to put comments in code for? Finally, this is my fault. I discovered an entertaining way of doing the calculation that was kind of cool (using convolutions over the state of the board). Unfortunately, it turns out to be really hard to implement in C#, so didn’t even manage to work out how to do that convolution in C#. It’s trivial in some high-level languages, but you need something matrix-orientated for it to really work. That’s most of it, really. The thoughts that people went away with: we put down our answers to questions like “What have you learnt?” and “What surprised you?”, “How are you going to do things differently?”, and most people said redoing the problem is really, really good for understanding it properly. People hate having a massive legacy codebase that they can’t change, so being able to attack something three different ways in an environment where the end-product isn’t important: that’s something people really enjoyed. Pair-programming: also people said that they wanted to do more of that, especially with TDD ping-pong, where you write the test and somebody else writes the code. Various people thought different things about immutables, but most people thought they were good, they promote functional programming. And TDD people found really hard. “Tell, don’t ask” people found really, really hard and really, really, really hard to do well. And the recursion just made things trickier to debug. But most people agreed that coderetreats are really cool, and we should do more of them.

  • Continuous Physics Engine's Collision Detection Techniques

    - by Griffin
    I'm working on a purely continuous physics engine, and I need to choose algorithms for broad and narrow phase collision detection. "Purely continuous" means I never do intersection tests, but instead want to find ways to catch every collision before it happens, and put each into "planned collisions" stack that is ordered by TOI. Broad Phase The only continuous broad-phase method I can think of is encasing each body in a circle and testing if each circle will ever overlap another. This seems horribly inefficient however, and lacks any culling. I have no idea what continuous analogs might exist for today's discrete collision culling methods such as quad-trees either. How might I go about preventing inappropriate and pointless broad test's such as a discrete engine does? Narrow Phase I've managed to adapt the narrow SAT to a continuous check rather than discrete, but I'm sure there's other better algorithms out there in papers or sites you guys might have come across. What various fast or accurate algorithm's do you suggest I use and what are the advantages / disatvantages of each? Final Note: I say techniques and not algorithms because I have not yet decided on how I will store different polygons which might be concave, convex, round, or even have holes. I plan to make a decision on this based on what the algorithm requires (for instance if I choose an algorithm that breaks down a polygon into triangles or convex shapes I will simply store the polygon data in this form).

  • Looking Back at MIX10

    - by WeigeltRo
    It’s the sad truth of my life that even though I’m fascinated by airplanes and flight in general since my childhood days, my body doesn’t like flying. Even the ridiculously short flights inside Germany are taking their toll on me each time. Now combine this with sitting in the cramped space of economy class for many hours on a transatlantic flight from Germany to Las Vegas and back, and factor in some heavy dose of jet lag (especially on my way eastwards), and you get an idea why after coming back home I had this question on my mind: Was it really worth it to attend MIX10? This of course is a question that will also be asked by my boss at Comma Soft (for other reasons, obviously), who decided to send me and my colleague Jens Schaller, to the MIX10 conference. (A note to my German readers: An dieser Stelle der Hinweis, dass Comma Soft noch Silverlight-Entwickler und/oder UI-Designer für den Standort Bonn sucht – aussagekräftige Bewerbungen bitte an [email protected]) Too keep things short: My answer is yes. Before I’ll go into detail, let me ask the heretical questions whether tech conferences in general still make sense. There was a time, where actually being at a tech conference gave you a head-start in regard to learning about new technologies. Nowadays this is no longer true, where every bit of information and every detail is immediately twittered, blogged and whatevered to death. In the case of MIX10 you even can download the video-taped sessions shortly after. So: Does visiting a conference still make sense? It depends on what you expect from a conference. It should be clear to everybody that you’ll neither get exclusive information, nor receive training in a small group. What a conference does offer that sitting in front of your computer does not can be summarized as follows: Focus Being away from work and home will help you to focus on the presented information. Of course there are always the poor guys who are haunted by their work (with mails and short text messages reporting the latest showstopper problem), but in general being out of your office makes a huge difference. Inspiration With the focus comes the emotional involvement. I find it much easier to absorb information if I feel that certain vibe when sitting in a session. This still means that I have put work into reviewing the information later, but it’s a better starting point. And all the impressions collected at a (good) conference combined lead to a higher motivation – be it by the buzz (“this is gonna be sooo cool!”) or by the fear to fall behind (“man, we’ll have work on this, or else…”). People At a conference it’s pretty easy to get into contact with other people during breakfast, lunch and other breaks. This is a good opportunity to get a feel for what other development teams are doing (on a very general level of course, nobody will tell you about their secret formula) and what they are thinking about specific technologies. So MIX10 did offer focus, inspiration and people, but that would have meant nothing without valuable content. When I (being a frontend developer with a strong interest in UI/UX) planned my visit to MIX10, I made the decision to focus on the "soft" topics of design, interaction and user experience. I figured that I would be bombarded with all the technical details about Silverlight 4 anyway in the weeks and months to come. Actually, I would have liked to catch a few technical sessions, but the agenda wasn’t exactly in favor of people interested in any kind of Silverlight and UI/UX/Design topics. That’s one of my few complaints about the conference – I would have liked one more day and/or more sessions per day. Overall, the quality of the workshops and sessions was pretty high. In fact, looking back at my collection of conferences I’ve visited in the past I’d say that MIX10 ranks somewhere near the top spot. Here’s an overview of the workshops/sessions I attended (I’ll leave out the keynotes): Day 0 (Workshops on Sunday) Design Fundamentals for Developers Robby Ingebretsen is the man! Great workshop in three parts with the perfect mix of examples, well-structured definition of terminology and the right dose of humor. Robby was part of the WPF team before founding his own company so he not only has a strong interest in design (and the skillz!) but also the technical background.   Design Tools and Techniques Originally announced to be held by Arturo Toledo, the Rosso brothers from ArcheType filled in for the first two parts, and Corrina Black had a pretty general part about the Windows Phone UI. The first two thirds were a mixed bag; the two guys definitely knew what they were talking about, and the demos were great, but the talk lacked the preparation and polish of a truly great presentation. Corrina was not allowed to go into too much detail before the keynote on Monday, but the session was still very interesting as it showed how much thought went into the Windows Phone UI (and there’s always a lot to learn when people talk about their thought process). Day 1 (Monday) Designing Rich Experiences for Data-Centric Applications I wonder whether there was ever a test-run for this session, but what Ken Azuma and Yoshihiro Saito delivered in the first 15 minutes of a 30-minutes-session made me walk out. A commercial for a product (just great: a video showing a SharePoint plug-in in an all-Japanese UI) combined with the most generic blah blah one could imagine. EPIC FAIL.   Great User Experiences: Seamlessly Blending Technology & Design I switched to this session from the one above but I guess I missed the interesting part – what I did catch was what looked like a “look at the cool stuff we did” without being helpful. Or maybe I was just in a bad mood after the other session.   The Art, Technology and Science of Reading This talk by Kevin Larson was very interesting, but was more a presentation of what Microsoft is doing in research (pretty impressive) and in the end lacked a bit the helpful advice one could have hoped for.   10 Ways to Attack a Design Problem and Come Out Winning Robby Ingebretsen again, and again a great mix of theory and practice. The clean and simple, yet effective, UI of the reader app resulted in a simultaneous “wow” of Jens and me. If you’d watch only one session video, this should be it. Microsoft has to bring Robby back next year! Day 2 (Tuesday) Touch in Public: Multi-touch Interaction Design for Kiosks & Architectural Experiences Very interesting session by Jason Brush, a great inspiration with many details to look out for in the examples. Exactly what I was hoping for – and then some!   Designing Bing: Heart and Science How hard can it be to design the UI for a search engine? An input field and a list of results, that should be it, right? Well, not so fast! The talk by Paul Ray showed the many iterations to finally get it right (up to the choice of a specific blue for the links). And yes, I want an eye-tracking device to play around with!   The Elephant in the Room When Nishant Kothary presented a long list of what his session was not about, I told to myself (not having the description text present) “Am I in the wrong talk? Should I leave?”. Boy, was I wrong. A great talk about human factors in the process of designing stuff.   An Hour with Bill Buxton Having seen Bill Buxton’s presentation in the keynote, I just had to see this man again – even though I didn’t know what to expect. Being more or less unplanned and intended to be more of a conversation, the session didn’t provide a wealth of immediately useful information. Nevertheless Bill Buxton was impressive with his huge knowledge of seemingly everything. But this could/should have been a session some when in the evening and not in parallel to at least two other interesting talks. Day 3 (Wednesday) Design the Ordinary, Like the Fixie This session by DL Byron and Kevin Tamura started really well and brought across the message to keep things simple. But towards the end the talk lost some of its steam. And, as a member of the audience pointed out, they kind of ignored their own advice when they used a fancy presentation software other then PowerPoint that sometimes got in the way of showing things.   Developing Natural User Interfaces Speaking of alternative presentation software, Joshua Blake definitely had the most remarkable alternative to PowerPoint, a self-written program called NaturalShow that was controlled using multi-touch on a touch screen. Not a PowerPoint-killer, but impressive nevertheless. The (excellent) talk itself was kind of eye-opening in regard to what “multi-touch support” on various platforms (WPF, Silverlight, Windows Phone) actually means.   Treat your Content Right The talk by Tiffani Jones Brown wasn’t even on my planned schedule, but somehow I ended up in that session – and it was great. And even for people who don’t necessarily have to write content for websites, some points made by Tiffani are valid in many places, notably wherever you put texts with more than a single word into your UI. Creating Effective Info Viz in Microsoft Silverlight The last session of MIX10 I attended was kind of disappointing. At first things were very promising, with Matthias Shapiro giving a brief but well-structured introduction to info graphics and interactive visualizations. Then the live-coding began and while the result was interesting, too much time was spend on wrestling to get the code working. Ending earlier than planned, the talk was a bit light on actual content, but at least it included a nice list of resources. Conclusion It could be felt all across MIX10, UIs will take a huge leap forward; in fact, there are enough examples that have already. People who both have the technical know-how and at least a basic understanding of design (“literacy” as Bill Buxton called it) are in high demand. The concept of the MIX conference and initiatives like design.toolbox shows that Microsoft understands very well that frontend developers have to acquire new knowledge besides knowing how to hack code and putting buttons on a form. There are extremely exciting times before us, with lots of opportunity for those who are eager to develop their skills, that is for sure.

  • Bingbot seems to be adding "ForceRecrawl: 0" to URLs when crawling my sites

    - by Louis Somers
    I'm seeing this in the iis-logs of two websites that I maintain: GET /an/existing/page/on/my/site+ForceRecrawl:+0 - 80 - 207.46.195.105 HTTP/1.1 Mozilla/5.0+(compatible;+bingbot/2.0;++http://www.bing.com/bingbot.htm) I get about one or two of these per day from these IP addresses: 207.46.195.105, 65.52.110.190.. an more, all belonging to msnbot-ip.search.msn.com Probably Microsoft has a bug in their crawler? Any way, doing a search on "ForceRecrawl: 0" in major search engines comes up with a bunch of random sites. Doing the search on StackOverflow or here gave no results (to my amazement). Am I the only one seeing this? I first noticed these on the 9th of this month, and I'm seeing them pass almost daily since... Another thing that I think is crazy, is that the URL http://www.bing.com/bingbot.htm redirects to mail.live.com (hotmail). Currently I'm returning 404's but I'm considering to catch these, strip the trailing " ForceRecrawl: 0" and process as if it were a legitimate url. Could anyone shed some light on this? Could it have to do with some configuration or so in Bing's Webmaster Tools?

  • WP7 &ndash; Oh, You Wanted to Develop On Your New Phone? That&rsquo;ll Cost Ya!

    - by D'Arcy Lussier
    Had an interesting Twitter convo today about WP7 development. Question was raised on how to use a WP7 device as the deployment target from within VS.NET. Thinking that this would be an *obvious* question, I replied that you need to set the right value in one of the drop lists in the IDE… I did this, hooked up my device, then tried to run my app, just as a final test that it was as easy as I thought it would be. It wasn’t. So first, your phone can’t be locked, so make sure you unlock it. Also, don’t kill the Zune software when you notice it automagically started – its needed for VS.NET to deploy to your device. Finally, you need to register your device for development. Aiden Caine has a great article on what you need to do for this, but in a nutshell you need to launch the Windows Phone Developer Registration program found in the Windows Phone Developer Tools folder. Now, here’s the catch to all of this: You must have a Windows Phone AppHub account. As in paid account. That’s right – to do development on your actual device, you need to have a $99 ($120 in Canada) AppHub developer membership. Now, I get this – if Microsoft didn’t put this restriction, then they’d be back in Mobile 6.x land where anyone could install whatever app to whoever, whenever, and without any standards being upheld. This is the same thing that Apple does with their marketplace, its not something unprecedented. But, it is something that will be new to the majority of Microsoft developers that have lived without application restrictions for years. Now, if you’re in the US then you have the opportunity to get a rebate on that $99 fee from Microsoft if you publish two apps successfully. You can get more details on this offer here.

  • Slick2D - Cannot instantiate the type Image

  • 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.

In the first post, JMS Step 1 - How to Create a Simple JMS Queue in Weblogic Server 11g we looked at how to create a JMS queue and its dependent objects in WebLogic Server. In the previous post, JMS Step 2 - Using the QueueSend.java Sample Program to Send a Message to a JMS Queue I showed how to write a message to that JMS queue using the QueueSend.java sample program. In this article, we will use a similar sample, the QueueReceive.java program to read the message from that queue. Please review the previous posts if you have not already done so, as they contain prerequisites for executing the sample in this article. 1. Source code The following java code will be used to read the message(s) from the JMS queue. As with the previous example, it is based on a sample program shipped with the WebLogic Server installation. The sample is not installed by default, but needs to be installed manually using the WebLogic Server Custom Installation option, together with many, other useful samples. You can either copy-paste the following code into your editor, or install all the samples. The knowledge base article in My Oracle Support: How To Install WebLogic Server and JMS Samples in WLS 10.3.x (Doc ID 1499719.1) describes how to install the samples. QueueReceive.java package examples.jms.queue; import java.util.Hashtable; import javax.jms.*; import javax.naming.Context; import javax.naming.InitialContext; import javax.naming.NamingException; /** * This example shows how to establish a connection to * and receive messages from a JMS queue. The classes in this * package operate on the same JMS queue. Run the classes together to * witness messages being sent and received, and to browse the queue * for messages. This class is used to receive and remove messages * from the queue. * * @author Copyright (c) 1999-2005 by BEA Systems, Inc. All Rights Reserved. */ public class QueueReceive implements MessageListener { // Defines the JNDI context factory. public final static String JNDI_FACTORY="weblogic.jndi.WLInitialContextFactory"; // Defines the JMS connection factory for the queue. public final static String JMS_FACTORY="jms/TestConnectionFactory"; // Defines the queue. public final static String QUEUE="jms/TestJMSQueue"; private QueueConnectionFactory qconFactory; private QueueConnection qcon; private QueueSession qsession; private QueueReceiver qreceiver; private Queue queue; private boolean quit = false; /** * Message listener interface. * @param msg message */ public void onMessage(Message msg) { try { String msgText; if (msg instanceof TextMessage) { msgText = ((TextMessage)msg).getText(); } else { msgText = msg.toString(); } System.out.println("Message Received: "+ msgText ); if (msgText.equalsIgnoreCase("quit")) { synchronized(this) { quit = true; this.notifyAll(); // Notify main thread to quit } } } catch (JMSException jmse) { System.err.println("An exception occurred: "+jmse.getMessage()); } } /** * Creates all the necessary objects for receiving * messages from a JMS queue. * * @param ctx JNDI initial context * @param queueName name of queue * @exception NamingException if operation cannot be performed * @exception JMSException if JMS fails to initialize due to internal error */ public void init(Context ctx, String queueName) throws NamingException, JMSException { qconFactory = (QueueConnectionFactory) ctx.lookup(JMS_FACTORY); qcon = qconFactory.createQueueConnection(); qsession = qcon.createQueueSession(false, Session.AUTO_ACKNOWLEDGE); queue = (Queue) ctx.lookup(queueName); qreceiver = qsession.createReceiver(queue); qreceiver.setMessageListener(this); qcon.start(); } /** * Closes JMS objects. * @exception JMSException if JMS fails to close objects due to internal error */ public void close()throws JMSException { qreceiver.close(); qsession.close(); qcon.close(); } /** * main() method. * * @param args WebLogic Server URL * @exception Exception if execution fails */ public static void main(String[] args) throws Exception { if (args.length != 1) { System.out.println("Usage: java examples.jms.queue.QueueReceive WebLogicURL"); return; } InitialContext ic = getInitialContext(args[0]); QueueReceive qr = new QueueReceive(); qr.init(ic, QUEUE); System.out.println( "JMS Ready To Receive Messages (To quit, send a \"quit\" message)."); // Wait until a "quit" message has been received. synchronized(qr) { while (! qr.quit) { try { qr.wait(); } catch (InterruptedException ie) {} } } qr.close(); } private static InitialContext getInitialContext(String url) throws NamingException { Hashtable env = new Hashtable(); env.put(Context.INITIAL_CONTEXT_FACTORY, JNDI_FACTORY); env.put(Context.PROVIDER_URL, url); return new InitialContext(env); } } 2. How to Use This Class 2.1 From the file system on Linux This section describes how to use the class from the file system of a WebLogic Server installation. Log in to a machine with a WebLogic Server installation and create a directory to contain the source and code matching the package name, e.g. span$HOME/examples/jms/queue. Copy the above QueueReceive.java file to this directory. Set the CLASSPATH and environment to match the WebLogic server environment. Go to $MIDDLEWARE_HOME/user_projects/domains/base_domain/bin  and execute . ./setDomainEnv.sh Collect the following information required to run the script: The JNDI name of the JMS queue to use In the WebLogic server console > Services > Messaging > JMS Modules > Module name, (e.g. TestJMSModule) > JMS queue name, (e.g. TestJMSQueue) select the queue and note its JNDI name, e.g. jms/TestJMSQueue The JNDI name of the connection factory to use to connect to the queue Follow the same path as above to get the connection factory for the above queue, e.g. TestConnectionFactory and its JNDI name e.g. jms/TestConnectionFactory The URL and port of the WebLogic server running the above queue Check the JMS server for the above queue and the managed server it is targeted to, for example soa_server1. Now find the port this managed server is listening on, by looking at its entry under Environment > Servers in the WLS console, e.g. 8001 The URL for the server to be passed to the QueueReceive program will therefore be t3://host.domain:8001 e.g. t3://jbevans-lx.de.oracle.com:8001 Edit Queue Receive .java and enter the above queue name and connection factory respectively under ... public final static String JMS_FACTORY="jms/TestConnectionFactory"; ... public final static String QUEUE="jms/TestJMSQueue"; ... Compile Queue Receive .java using javac Queue Receive .java Go to the source’s top-level directory and execute it using java examples.jms.queue.Queue Receive   t3://jbevans-lx.de.oracle.com:8001 This will print a message that it is ready to receive messages or to send a “quit” message to end. The program will read all messages in the queue and print them to the standard output until it receives a message with the payload “quit”. 2.2 From JDeveloper The steps from JDeveloper are the same as those used for the previous program QueueSend.java, which is used to send a message to the queue. So we won't repeat them here. Please see the previous blog post at JMS Step 2 - Using the QueueSend.java Sample Program to Send a Message to a JMS Queue and apply the same steps in that example to the QueueReceive.java program. This concludes the example. In the following post we will create a BPEL process which writes a message based on an XML schema to the queue.

  • 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!

  • Flash Technology Can Revolutionize your IT Infrastructure

    - by kimberly.billings
    A recent article in the Data Center Journal written by Mark Teter outlines how flash is becoming a disruptive technology in the data center and how it will soon replace HDDs in the storage hierarchy. As Teter explains, the drivers behind this trend are lower cost/performance and power savings; flash is over 100x faster for reads than the fastest HDD, and while it is expensive, it can produce dramatic reductions in the cost of performance as measured in Input/Outputs per second (IOPS). What's more, flash consumes 1/5th the power of HDD, so it's faster AND greener. Teter writes, "when appropriately used, flash turns the current economics of IT performance on its head. That's disruptive." Exadata Smart Flash Cache in the Sun Oracle Database Machine makes intelligent use of flash storage to deliver extreme performance for OLTP and mixed workloads. It intelligently caches data from the Oracle Database replacing slow mechanical I/O operations to disk with very rapid flash memory operations. Exadata Smart Flash Cache is the fundamental technology of the Sun Oracle Database Machine that enables the processing of up to 1 million random I/O operations per second (IOPS), and the scanning of data within Exadata storage at up to 50 GB/second. Are you incorporating flash into your storage strategy? Let us know! Read more: "Flash technology can revolutionize your IT infrastructure", The Data Center Journal, March 30, 2010.

  • Experience your music in a whole new way with Zune for PC

    - by Matthew Guay
    Tired of the standard Media Player look and feel, and want something new and innovative?  Zune offers a fresh, new way to enjoy your music, videos, pictures, and podcasts, whether or not you own a Zune device. Microsoft started out on a new multimedia experience for PCs and mobile devices with the launch of the Zune several years ago.  The Zune devices have been well received and noted for their innovative UI, and the Zune HD’s fluid interface is the foundation for the widely anticipated Windows Phone 7.  But regardless of whether or not you have a Zune Device, you can still use the exciting new UI and services directly from your PC.  Zune for Windows is a very nice media player that offers a music and video store and wide support for multimedia formats including those used in Apple products.  And if you enjoy listening to a wide variety of music, it also offers the Zune Pass which lets you stream an unlimited number of songs to your computer and download 10 songs for keeps per month for $14.99/month. Or you can do a pre-paid music card as well.  It does all this using the new Metro UI which beautifully shows information using text in a whole new way.  Here’s a quick look at setting up and using Zune on your PC. Getting Started Download the installer (link below), and run it to begin setup.  Please note that Zune offers a separate version for computers running the 64 bit version of Windows Vista or 7, so choose it if your computer is running these. Once your download is finished, run the installer to setup Zune on your computer.  Accept the EULA when prompted. If there are any updates available, they will automatically download and install during the setup.  So, if you’re installing Zune from a disk (for example, one packaged with a Zune device), you don’t have to worry if you have the latest version.  Zune will proceed to install on your computer.   It may prompt you to restart your computer after installation; click Restart Now so you can proceed with your Zune setup.  The reboot appears to be for Zune device support, and the program ran fine otherwise without rebooting, so you could possibly skip this step if you’re not using a Zune device.  However, to be on the safe side, go ahead and reboot. After rebooting, launch Zune.  It will play a cute introduction video on first launch; press skip if you don’t want to watch it. Zune will now ask you if you want to keep the default settings or change them.  Choose Start to keep the defaults, or Settings to customize to your wishes.  Do note that the default settings will set Zune as your default media player, so click Settings if you wish to change this. If you choose to change the default settings, you can change how Zune finds and stores media on your computer.  In Windows 7, Zune will by default use your Windows 7 Libraries to manage your media, and will in fact add a new Podcasts library to Windows 7. If your media is stored on another location, such as on a server, then you can add this to the Library.  Please note that this adds the location to your system-wide library, not just the Zune player. There’s one last step.  Enter three of your favorite artists, and Zune will add Smart DJ mixes to your Quickplay list based on these.  Some less famous or popular artists may not be recognized, so you may have to try another if your choice isn’t available.  Or, you can click Skip if you don’t want to do this right now. Welcome to Zune!  This is the default first page, QuickPlay, where you can easily access your pinned and new items.   If you have a Zune account, or would like to create a new one, click Sign In on the top. Creating a new account is quick and simple, and if you’re new to Zune, you can try out a 14 day trial of Zune Pass for free if you want. Zune allows you to share your listening habits and favorites with friends or the world, but you can turn this off or change it if you like. Using Zune for Windows To access your media, click the Collection link on the top left.  Zune will show all the media you already have stored on your computer, organized by artist and album. Right-click on any album, and you choose to have Zune find album art or do a variety of other tasks with the media.   When playing media, you can view it in several unique ways.  First, the default Mix view will show related tracks to the music you’re playing from Smart DJ.  You can either play these fully if you’re a Zune Pass subscriber, or otherwise you can play 30 second previews. Then, for many popular artists, Zune will change the player background to show pictures and information in a unique way while the music is playing.  The information may range from history about the artist to the popularity of the song being played.   Zune also works as a nice viewer for the pictures on your computer. Start a slideshow, and Zune will play your pictures with nice transition effects and music from your library. Zune Store The Zune Store offers a wide variety of music, TV shows, and videos for purchase.  If you’re a Zune Pass subscriber, you can listen to or download any song without purchasing it; otherwise, you can preview a 30 second clip first. Zune also offers a wide selection of Podcasts you can subscribe to for free. Using Zune for PC with a Zune Device If you have a Zune device attached to your computer, you can easily add media files to it by simply dragging them to the Zune device icon in the left corner.  In the future, this will also work with Windows Phone 7 devices. If you have a Zune HD, you can also download and add apps to your device. Here’s the detailed information window for the weather app.  Click Download to add it to your device.   Mini Mode The Zune player generally takes up a large portion of your screen, and is actually most impressive when run maximized.  However, if you’re simply wanting to enjoy your tunes while you’re using your computer, you can use the Mini mode to still view music info and control Zune in a smaller mode.  Click the Mini Player button near the window control buttons in the top right to activate it. Now Zune will take up much less of your desktop.  This window will stay on top of other windows so you can still easily view and control it. Zune will display an image of the artist if one is available, and this shows up in Mini mode more often than it does in the full mode. And, in Windows 7, you could simply minimize Zune as you can control it directly from the taskbar thumbnail preview.   Even more controls are available from Zune’s jumplist in Windows 7.  You can directly access your Quickplay links or choose to shuffle all music without leaving the taskbar. Settings Although Zune is designed to be used without confusing menus and settings, you can tweak the program to your liking from the settings panel.  Click Settings near the top left of the window. Here you can change file storage, types, burn, metadata, and many more settings.  You can also setup Zune to stream media to your XBOX 360 if you have one.   You can also customize Zune’s look with a variety of modern backgrounds and gradients. Conclusion If you’re ready for a fresh way to enjoy your media, Zune is designed for you.  It’s innovative UI definitely sets it apart from standard media players, and is very pleasing to use.  Zune is especially nice if your computer is using XP, Vista Home Basic, or 7 Starter as these versions of Windows don’t include Media Center.  Additionally, the mini player mode is a nice touch that brings a feature of Windows 7’s Media Player to XP and Vista.  Zune is definitely one of our favorite music apps.  Try it out, and get a fresh view of your music today!
