• [MINI HOW-TO] Redeem Pre-paid Zune Card Points for Zune Marketplace Media

  - by Mysticgeek

  If you don’t want to pay the monthly fee for a Zune Pass, one option is buying a pre-paid Zune card. Here we take a look at how to redeem the Zune card points so you can get music for your Zune or Zune HD. Of course the first thing you will need to do is buy a Zune card. You can find them for different amounts at most retail locations that sell Zune’s like Walmart, Best Buy…etc. When you purchase the card make sure the cashier activates it.   Now open up your Zune desktop software and sign in if you aren’t already. Go into Settings \ Account and under Microsoft Points click on Redeem Code. Now enter the code from the back of the card that you scratch off and hit Next. After entering in your code successfully it asks for your contact information, which seems odd considering you’re using a prepaid card. You may want to enter in a fictitious address and phone number if concerned about privacy…then click Next. The only thing you might want to enter in legitimately is your email address to get a confirmation email. You’re given a Thank you message… And back in your Account Settings you’ll see the points have been added. Now you can go shopping for music, videos, TV shows, and more at the Zune Marketplace. If you don’t want to give up your credit card info and pay the monthly fee for the Zune Pass, using prepaid card to purchase music as you go is a good alternative.

• Talking JavaOne with Rock Star Adam Bien

  - by Janice J. Heiss

  Among the most celebrated developers in recent years, especially in the domain of Java EE and JavaFX, is consultant Adam Bien, who, in addition to being a JavaOne Rock Star for Java EE sessions given in 2009 and 20011, is a Java Champion, the winner of Oracle Magazine’s 2011 Top Java Developer of the Year Award, and recently won a 2012 JAX Innovation Award as a top Java Ambassador. Bien will be presenting the following sessions: TUT3907 - Java EE 6/7: The Lean Parts CON3906 - Stress-Testing Java EE 6 Applications Without Stress CON3908 - Building Serious JavaFX 2 Applications CON3896 - Interactive Onstage Java EE Overengineering I spoke with Bien to get his take on Java today. He expressed excitement that the smallest companies and startups are showing increasing interest in Java EE. “This is a very good sign,” said Bien. “Only a few years ago J2EE was mostly used by larger companies -- now it becomes interesting even for one-person shows. Enterprise Java events are also extremely popular. On the Java SE side, I'm really excited about Project Nashorn.” Nashorn is an upcoming JavaScript engine, developed fully in Java by Oracle, and based on the Da Vinci Machine (JSR 292) which is expected to be available for Java 8.   Bien expressed concern about a common misconception regarding Java's mediocre productivity. “The problem is not Java,” explained Bien, “but rather systems built with ancient patterns and approaches. Sometimes it really is ‘Cargo Cult Programming.’ Java SE/EE can be incredibly productive and lean without the unnecessary and hard-to-maintain bloat. The real problems are ‘Ivory Towers’ and not Java’s lack of productivity.” Bien remarked that if there is one thing he wanted Java developers to understand it is that, "Premature optimization is the root of all evil. Or at least of some evil. Modern JVMs and application servers are hard to optimize upfront. It is far easier to write simple code and measure the results continuously. Identify the hotspots first, then optimize.” He advised Java EE developers to, “Rethink everything you know about Enterprise Java. Before you implement anything, ask the question: ‘Why?’ If there is no clear answer -- just don't do it. Most well known best practices are outdated. Focus your efforts on the domain problem and not the technology.” Looking ahead, Bien said, “I would like to see open source application servers running directly on a hypervisor. Packaging the whole runtime in a single file would significantly simplify the deployment and operations.”Check out a recent Java Magazine interview with Bien about his Java EE 6 stress monitoring tool here.

• How To Run A Shell Script Again And Again Having X Interval Of Time?

  - by Muhammad Hassan

  I have a shell script in my Ubuntu Server 14.04 LTS at ./ShellScript.sh. I setup /etc/rc.local to run the shell script after boot but before login using below code. Run this: sudo nano /etc/rc.local then add following and save. #!/bin/sh -e # # rc.local # # This script is executed at the end of each multiuser runlevel. # Make sure that the script will "exit 0" on success or any other # value on error. # # In order to enable or disable this script just change the execution # bits. # # By default this script does nothing. #!/bin/bash ./ShellScript.sh exit 0 Now I want to run/execute this shell script again and again having 15min of time interval between every run after boot but before login. So Can I do it? Update 1:) When I run crontab -e then I got the following. Now What to do? no crontab for root - using an empty one Select an editor. To change later, run 'select-editor'. 1. /bin/ed 2. /bin/nano <---- easiest 3. /usr/bin/vim.basic 4. /usr/bin/vim.tiny Choose 1-4 [2]: After selecting 2, I got crontab: "/usr/bin/sensible-editor" exited with status 2 UPDATE 2:) Update ShellScript.sh like below... #!/bin/bash # Testing ShellScript... while true do echo "ShellScript Start Running..." ********************************** All My Shell Script Codes/Script/Commands ********************************** echo "ShellScript End Running..." exit 0 sleep 900 done Then Run this: sudo nano /etc/rc.local then add following and save. #!/bin/sh -e # # rc.local # # This script is executed at the end of each multiuser runlevel. # Make sure that the script will "exit 0" on success or any other # value on error. # # In order to enable or disable this script just change the execution # bits. # # By default this script does nothing. sh ./ShellScript.sh & exit 0

• New Pluralsight Course: HTML5 Canvas Fundamentals

  - by dwahlin

    I just finished up a new course for Pluralsight titled HTML5 Canvas Fundamentals that I had a blast putting together. It’s all about the client and involves a lot of pixel manipulation and graphics creation which is challenging and fun at the same time. The goal of the course is to walk you through the fundamentals, start a gradual jog into the API functions, and then start sprinting as you learn how to build a business chart canvas application from scratch that uses many of the available APIs . It’s fun stuff and very useful in a variety of scenarios including Web (desktop or mobile) and even Windows 8 Metro applications. Here’s a sample video from the course that talks about building a simple bar chart using the HTML5 Canvas:   Additional details about the course are shown next.   HTML5 Canvas Fundamentals The HTML5 Canvas provides a powerful way to render graphics, charts, and other types of visual data without relying on plugins such as Flash or Silverlight. In this course you’ll be introduced to key features available in the canvas API and see how they can be used to render shapes, text, video, images, and more. You’ll also learn how to work with gradients, perform animations, transform shapes, and build a custom charting application from scratch.

• Advice Needed: Developers blocked by waiting on code to merge from another branch using GitFlow

  - by fogwolf

  Our team just made the switch from FogBugz & Kiln/Mercurial to Jira & Stash/Git. We are using the Git Flow model for branching, adding subtask branches off of feature branches (relating to Jira subtasks of Jira features). We are using Stash to assign a reviewer when we create a pull request to merge back into the parent branch (usually develop but for subtasks back into the feature branch). The problem we're finding is that even with the best planning and breakdown of feature cases, when multiple developers are working together on the same feature, say on the front-end and back-end, if they are working on interdependent code that is in separate branches one developer ends up blocking the other. We've tried pulling between each others' branches as we develop. We've also tried creating local integration branches each developer can pull from multiple branches to test the integration as they develop. Finally, and this seems to work possibly the best for us so far, though with a bit more overhead, we have tried creating an integration branch off of the feature branch right off the bat. When a subtask branch (off of the feature branch) is ready for a pull request and code review, we also manually merge those change sets into this feature integration branch. Then all interested developers are able to pull from that integration branch into other dependent subtask branches. This prevents anyone from waiting for any branch they are dependent upon to pass code review. I know this isn't necessarily a Git issue - it has to do with working on interdependent code in multiple branches, mixed with our own work process and culture. If we didn't have the strict code-review policy for develop (true integration branch) then developer 1 could merge to develop for developer 2 to pull from. Another complication is that we are also required to do some preliminary testing as part of the code review process before handing the feature off to QA.This means that even if front-end developer 1 is pulling directly from back-end developer 2's branch as they go, if back-end developer 2 finishes and his/her pull request is sitting in code review for a week, then front-end developer 2 technically can't create his pull request/code review because his/her code reviewer can't test because back-end developer 2's code hasn't been merged into develop yet. Bottom line is we're finding ourselves in a much more serial rather than parallel approach in these instance, depending on which route we go, and would like to find a process to use to avoid this. Last thing I'll mention is we realize by sharing code across branches that haven't been code reviewed and finalized yet we are in essence using the beta code of others. To a certain extent I don't think we can avoid that and are willing to accept that to a degree. Anyway, any ideas, input, etc... greatly appreciated. Thanks!

• Victor Grazi, Java Champion!

  - by Tori Wieldt

  Congratulations to Victor Grazi, who has been made a Java Champion! He was nominated by his peers and selected as a Java Champion for his experience as a developer, and his work in the Java and Open Source communities. Grazi is a Java evangelist and serves on the Executive Committee of the Java Community Process, representing Credit Suisse - the first non-technology vendor on the JCP. He also arranges the NY Java SIG meetings at Credit Suisse's New York campus each month, and he says it has been a valuable networking opportunity. He also is the spec lead for JSR 354, the Java Money and Currency API. Grazi has been building real time financial systems in Java since JDK version 1.02! In 1996, the internet was just starting to happen, Grazi started a dot com called Supermarkets to Go, that provided an on-line shopping presence to supermarkets and grocers. Grazi wrote most of the code, which was a great opportunity for him to learn Java and UI development, as well as database management. Next, he went to work at Bank of NY building a trading system. He studied for Java certification, and he noted that getting his certification was a game changer because it helped him started to learn the nuances of the Java language. He has held other development positions, "You may have noticed that you don't get as much junk mail from Citibank as you used to - that is thanks to one of my projects!" he told us. Grazi joined Credit Suisse in 2005 and is currently Vice President on the central architecture team. Grazi is proud of his open source project, Java Concurrent Animated, a series of animations that visualize the functionality of the components in the java.util.concurrent library. "It has afforded me the opportunity to speak around the globe" and because of it, has discovered that he really enjoys doing public presentations. He is a fine addition to the Java Champions program. The Java Champions are an exclusive group of passionate Java technology and community leaders who are community-nominated and selected under a project sponsored by Oracle. Nominees are named and selected through a peer review process. Java Champions get the opportunity to provide feedback, ideas, and direction that will help Oracle grow the Java Platform. This interchange may be in the form of technical discussions and/or community-building activities with Oracle's Java Development and Developer Program teams.

• A Generic, IDisposable WCF Service Client

  - by Steve Wilkes

  WCF clients need to be cleaned up properly, but as they're usually auto-generated they don't implement IDisposable. I've been doing a fair bit of WCF work recently, so I wrote a generic WCF client wrapper which effectively gives me a disposable service client. The ServiceClientWrapper is constructed using a WebServiceConfig instance, which contains a Binding, an EndPointAddress, and whether the client should ignore SSL certificate errors - pretty useful during testing! The Binding can be created based on configuration data or entirely programmatically - that's not the client's concern. Here's the service client code: using System; using System.Net; using System.Net.Security; using System.ServiceModel; public class ServiceClientWrapper<TService, TChannel> : IDisposable     where TService : ClientBase<TChannel>     where TChannel : class {     private readonly WebServiceConfig _config;     private TService _serviceClient;     public ServiceClientWrapper(WebServiceConfig config)     {         this._config = config;     }     public TService CreateServiceClient()     {         this.DisposeExistingServiceClientIfRequired();         if (this._config.IgnoreSslErrors)         {             ServicePointManager.ServerCertificateValidationCallback =                 (obj, certificate, chain, errors) => true;         }         else         {             ServicePointManager.ServerCertificateValidationCallback =                 (obj, certificate, chain, errors) => errors == SslPolicyErrors.None;         }         this._serviceClient = (TService)Activator.CreateInstance(             typeof(TService),             this._config.Binding,             this._config.Endpoint);         if (this._config.ClientCertificate != null)         {             this._serviceClient.ClientCredentials.ClientCertificate.Certificate =                 this._config.ClientCertificate;         }         return this._serviceClient;     }     public void Dispose()     {         this.DisposeExistingServiceClientIfRequired();     }     private void DisposeExistingServiceClientIfRequired()     {         if (this._serviceClient != null)         {             try             {                 if (this._serviceClient.State == CommunicationState.Faulted)                 {                     this._serviceClient.Abort();                 }                 else                 {                     this._serviceClient.Close();                 }             }             catch             {                 this._serviceClient.Abort();             }             this._serviceClient = null;         }     } } A client for a particular service can then be created something like this: public class ManagementServiceClientWrapper :     ServiceClientWrapper<ManagementServiceClient, IManagementService> {     public ManagementServiceClientWrapper(WebServiceConfig config)         : base(config)     {     } } ...where ManagementServiceClient is the auto-generated client class, and the IManagementService is the auto-generated WCF channel class - and used like this: using(var serviceClientWrapper = new ManagementServiceClientWrapper(config)) {     serviceClientWrapper.CreateServiceClient().CallService(); } The underlying WCF client created by the CreateServiceClient() will be disposed after the using, and hey presto - a disposable WCF service client.

• JavaOne Rock Star – Adam Bien

  Among the most celebrated developers in recent years, especially in the domain of Java EE and JavaFX, is consultant Adam Bien, who, in addition to being a JavaOne Rock Star for Java EE sessions given in 2009 and 2011, is a Java Champion, the winner of Oracle Magazine’s 2011 Top Java Developer of the Year Award, and recently won a 2012 JAX Innovation Award as a top Java Ambassador. Bien will be presenting the following sessions: TUT3907 - Java EE 6/7: The Lean Parts CON3906 - Stress-Testing Java EE 6 Applications Without Stress CON3908 - Building Serious JavaFX 2 Applications CON3896 - Interactive Onstage Java EE Overengineering I spoke with Bien to get his take on Java today.

• What is Database Continuous Integration?

  - by David Atkinson

  Although not everyone is practicing continuous integration, many have at least heard of the concept. A recent poll on www.simple-talk.com indicates that 40% of respondents are employing the technique. It is widely accepted that the earlier issues are identified in the development process, the lower the cost to the development process. The worst case scenario, of course, is for the bug to be found by the customer following the product release. A number of Agile development best practices have evolved to combat this problem early in the development process, including pair programming, code inspections and unit testing. Continuous integration is one such Agile concept that tackles the problem at the point of committing a change to source control. This can alternatively be run on a regular schedule. This triggers a sequence of events that compiles the code and performs a variety of tests. Often the continuous integration process is regarded as a build validation test, and if issues were to be identified at this stage, the testers would simply not 'waste their time ' and touch the build at all. Such a ‘broken build’ will trigger an alert and the development team’s number one priority should be to resolve the issue. How application code is compiled and tested as part of continuous integration is well understood. However, this isn’t so clear for databases. Indeed, before I cover the mechanics of implementation, we need to decide what we mean by database continuous integration. For me, database continuous integration can be implemented as one or more of the following: 1)      Your application code is being compiled and tested. You therefore need a database to be maintained at the corresponding version. 2)      Just as a valid application should compile, so should the database. It should therefore be possible to build a new database from scratch. 3)     Likewise, it should be possible to generate an upgrade script to take your already deployed databases to the latest version. I will be covering these in further detail in future blogs. In the meantime, more information can be found in the whitepaper linked off www.red-gate.com/ci If you have any questions, feel free to contact me directly or post a comment to this blog post.

• Visual Studio 2010 RC &ndash; Silverlight 4 and WCF RIA Services Development - Updates from MIX Anno

  - by Harish Ranganathan

  MIX is happening and there is a lot of excitement around the various releases such as the Windows Phone 7 Developer Preview, IE9 Platform Preview and few other announcements that have been made.  Clearly, the Windows Phone 7 Developer Preview has generated the maximum interest and opened a plethora of opportunities for .NET Developers.  It also takes the mobile development to a new generation and doesn’t force developers to learn different programming language. Along with this, few other releases have been out.  The most anticipated Silverlight 4 RC is out and its corresponding templates are also out there for you to download.  Once VS 2010 RC was released, it was much of a disappointment that it doesn’t support SL4 development as well as the SL4 Business Application Development (a.k.a. WCF RIA Services).   There were few workarounds though nothing concrete.  Earlier I had written about how the WCF RIA Services Preview does work with ASP.NET Development using VS 2010 RC. However, with the release of SL4 RC and the corresponding tooling updates, one can develop for both SL4 as well as SL4 + WCF RIA Services using VS 2010 RC.  This is kind of important and keeps the continuum going until VS 2010 RTMs.  So, the purpose of this post is to quickly give the updates and links to install the relevant tools. Silverlight 4 RC Runtime Windows Runtime or the Mac Runtime Silverlight 4 RC Developer Tools for Visual Studio 2010 RC Silverlight 4 Tools for Visual Studio 2010 (this would install the Runtime as well automatically) Expression Blend 4 Beta Expression Blend 4 Beta If you install the SL4 RC Developer Tools, it also installs the WCF RIA Services Preview automatically.  You just need to install the WCF RIA Services Toolkit that can be downloaded from Install the WCF RIA Services Toolkit Of course you can also just install the WCF RIA Services for VS 2010 RC separately (without SL4 Tools) from here Kindly note, all the above mentioned links are with respect to Visual Studio 2010 RC edition.  If you are developing with VS 2008, then you can just target SL3 (as I write this, there seems to be no official support for developing SL4 with VS 2008) and the related tools can be downloaded from http://www.silverlight.net/getstarted/ Basically you need to download SL 3 Runtime, SDK, Expression Blend 3 and the Silverlight Toolkit.  All the links for the download are available in the above mentioned page. Also, a version of WCF RIA Services that is supported in VS 2008 is available for download at WCF RIA Services Beta for VS 2008 I know there are far too many things to keep in mind.  So, I put a flowchart that could help with depicting it pictorial.  Note that this is just my own imagination and doesn’t cover all scenarios.  for example, if you are neither developing for Webform, Silverlight, you end up nowhere whereas in actual scenario you may want to develop Desktop, Services, Console, Game and what not.  So, keep in mind this is just Web. Cheers !!!

• Dependency Injection/IoC container practices when writing frameworks

  - by Dave Hillier

  I've used various IoC containers (Castle.Windsor, Autofac, MEF, etc) for .Net in a number of projects. I have found they tend to encourage a number of bad practices. Are there any established practices for IoC container use, particularly when providing a platform/framework? My aim as a framework writer is to make code as simple and as easy to use as possible. I'd rather write one line of code to construct an object than ten or even just two. For example, a couple of code smells that I've noticed and don't have good suggestions to: Large number of parameters (5) for constructors. Creating services tends to be complex; all of the dependencies are injected via the constructor - despite the fact that the components are rarely optional (except for maybe in testing). Lack of private and internal classes; this one may be a specific limitation of using C# and Silverlight, but I'm interested in how it is solved. It's difficult to tell what a frameworks interface is if all the classes are public; it allows me access to private parts that I probably shouldnt touch. Coupling the object lifecycle to the IoC container. It is often difficult to manually construct the dependencies required to create objects. Object lifecycle is too often managed by the IoC framework. I've seen projects where most classes are registered as Singletons. You get a lack of explicit control and are also forced to manage the internals (it relates to the above point, all classes are public and you have to inject them). For example, .Net framework has many static methods. such as, DateTime.UtcNow. Many times I have seen this wrapped and injected as a construction parameter. Depending on concrete implementation makes my code hard to test. Injecting a dependency makes my code hard to use - particularly if the class has many parameters. How do I provide both a testable interface, as well as one that is easy to use? What are the best practices?

• SQL SERVER – A Puzzle Part 3 – Fun with SEQUENCE in SQL Server 2012 – Guess the Next Value

  - by pinaldave

  Before continuing this blog post – please read the two part of the SEQUENCE Puzzle here A Puzzle – Fun with SEQUENCE in SQL Server 2012 – Guess the Next Value and A Puzzle Part 2 – Fun with SEQUENCE in SQL Server 2012 – Guess the Next Value Where we played a simple guessing game about predicting next value. The answers the of puzzle is shared on the blog posts as a comment. Now here is the next puzzle based on yesterday’s puzzle. I recently shared the puzzle of the blog post on local user group and it was appreciated by attendees. First execute the script which I have written here. Today’s script is bit different than yesterday’s script as well it will require you to do some service related activities. I suggest you try this on your personal computer’s test environment when no one is working on it. Do not attempt this on production server as it will for sure get you in trouble. The purpose to learn how sequence behave during the unexpected shutdowns and services restarts. Now guess what will be the next value as requested in the query. USE AdventureWorks2012 GO -- Create sequence CREATE SEQUENCE dbo.SequenceID AS BIGINT START WITH 1 INCREMENT BY 1 MINVALUE 1 MAXVALUE 500 CYCLE CACHE 100; GO -- Following will return 1 SELECT next value FOR dbo.SequenceID; ------------------------------------- -- simulate server crash by restarting service -- do not attempt this on production or any server in use ------------------------------------ -- Following will return ??? SELECT next value FOR dbo.SequenceID; -- Clean up DROP SEQUENCE dbo.SequenceID; GO Once the server is restarted what will be the next value for SequenceID. We can learn interesting trivia’s about this new feature of SQL Server using this puzzle. Hint: Pay special attention to the difference between new number and earlier number. Can you see the same number in the definition of the CREATE SEQUENCE? Bonus Question: How to avoid the behavior demonstrated in above mentioned query. Does it have any effect of performance? I suggest you try to attempt to answer this question without running this code in SQL Server 2012. You can restart SQL Server using command prompt as well. I will follow up of the answer in comments below. Recently my friend Vinod Kumar wrote excellent blog post on SQL Server 2012: Using SEQUENCE, you can head over there for learning sequence in details.

• Will my self-taught code be fine, or should I take it to the professional level?

  - by G1i1ch

  Lately I've been getting professional work, hanging out with other programmers, and making friends in the industry. The only thing is I'm 100% self-taught. It's caused my style to extremely deviate from the style of those that are properly trained. It's the techniques and organization of my code that's different. It's a mixture of several things I do. I tend to blend several programming paradigms together. Like Functional and OO. I lean to the Functional side more than OO, but I see the use of OO when something would make more sense as an abstract entity. Like a game object. Next I also go the simple route when doing something. When in contrast, it seems like sometimes the code I see from professional programmers is complicated for the sake of it! I use lots of closures. And lastly, I'm not the best commenter. I find it easier just to read through my code than reading the comment. And most cases I just end up reading the code even if there are comments. Plus I've been told that, because of how simply I write my code, it's very easy to read it. I hear professionally trained programmers go on and on about things like unit tests. Something I've never used before so I haven't even the faintest idea of what they are or how they work. Lots and lots of underscores "_", which aren't really my taste. Most of the techniques I use are straight from me, or a few books I've read. Don't know anything about MVC, I've heard a lot about it though with things like backbone.js. I think it's a way to organize an application. It just confuses me though because by now I've made my own organizational structures. It's a bit of a pain. I can't use template applications at all when learning something new like with Ubuntu's Quickly. I have trouble understanding code that I can tell is from someone trained. Complete OO programming really leaves a bad taste in my mouth, yet that seems to be what EVERYONE else is strictly using. It's left me not that confident in the look of my code, or wondering whether I'll cause sparks when joining a company or maybe contributing to open source projects. In fact I'm rather scared of the fact that people will eventually be checking out my code. Is this just something normal any programmer goes through or should I really look to change up my techniques?

• Say goodbye to System.Reflection.Emit (any dynamic proxy generation) in WinRT

  - by mbrit

  tl;dr - Forget any form of dynamic code emitting in Metro-style. It's not going to happen.Over the past week or so I've been trying to get Moq (the popular open source TDD mocking framework) to work on WinRT. Irritatingly, the day before Release Preview was released it was actually working on Consumer Preview. However in Release Preview (RP) the System.Reflection.Emit namespace is gone. Forget any form of dynamic code generation and/or MSIL injection.This kills off any project based on the popular Castle Project Dynamic Proxy component, of which Moq is one example. You can at this point in time not perform any form of mocking using dynamic injection in your Metro-style unit testing endeavours.So let me take you through my journey on this, so that other's don't have to...The headline fact is that you cannot load any assembly that you create at runtime. WinRT supports one Assembly.Load method, and that takes the name of an assembly. That has to be placed within the deployment folder of your app. You cannot give it a filename, or stream. The methods are there, but private. Try to invoke them using Reflection and you'll be met with a caspol exception.You can, in theory, use Rotor to replace SRE. It's all there, but again, you can't load anything you create.You can't write to your deployment folder from within your Metro-style app. But, can you use another service on the machine to move a file that you create into the deployment folder and load it? Not really.The networking stack in Metro-style is intentionally "damaged" to prevent socket communication from Metro-style to any end-point on the local machine. (It just times out.) This militates against an approach where your Metro-style app can signal a properly installed service on the machine to create proxies on its behalf. If you wanted to do this, you'd have to route the calls through a C&C server somewhere. The reason why Microsoft has done this is obvious - taking out SRE know means they don't have to do it in an emergency later. The collateral damage in removing SRE is that you can't do mocking in test mode, but you also can't do any form of injection in production mode. There are plenty of reasons why enterprise apps might want to do this last point particularly. At CP, the assumption was that their inspection tools would prevent SRE being used as a malware vector - it now seems they are less confident about that. (For clarity, the risk here is in allowing a nefarious program to download instructions from a C&C server and make up executable code on the fly to run, getting around the marketplace restrictions.)So, two things:- System.Reflection.Emit is gone in Metro-style/WinRT. Get over it - dynamic, on-the-fly code generation is not going to to happen.- I've more or less got a version of Moq working in Metro-style. This is based on the idea of "baking" the dynamic proxies before you use them. You can find more information here: https://github.com/mbrit/moqrt

• Interviews: Going Beyond the Technical Quiz

  - by Tony Davis

  All developers will be familiar with the basic format of a technical interview. After a bout of CV-trawling to gauge basic experience, strengths and weaknesses, the interview turns technical. The whiteboard takes center stage and the challenge is set to design a function or query, or solve what on the face of it might seem a disarmingly simple programming puzzle. Most developers will have experienced those few panic-stricken moments, when one’s mind goes as blank as the whiteboard, before un-popping the marker pen, and hopefully one’s mental functions, to work through the problem. It is a way to probe the candidate’s knowledge of basic programming structures and techniques and to challenge their critical thinking. However, these challenges or puzzles, often devised by some of the smartest brains in the development team, have a tendency to become unnecessarily ‘tricksy’. They often seem somewhat academic in nature. While the candidate straight out of IT school might breeze through the construction of a Markov chain, a candidate with bags of practical experience but less in the way of formal training could become nonplussed. Also, a whiteboard and a marker pen make up only a very small part of the toolkit that a programmer will use in everyday work. I remember vividly my first job interview, for a position as technical editor. It went well, but after the usual CV grilling and technical questions, I was only halfway there. Later, they sat me alongside a team of editors, in front of a computer loaded with MS Word and copy of SQL Server Query Analyzer, and my task was to edit a real chapter for a real SQL Server book that they planned to publish, including validating and testing all the code. It was a tough challenge but I came away with a sound knowledge of the sort of work I’d do, and its context. It makes perfect sense, yet my impression is that many organizations don’t do this. Indeed, it is only relatively recently that Red Gate started to move over to this model for developer interviews. Now, instead of, or perhaps in addition to, the whiteboard challenges, the candidate can expect to sit with their prospective team, in front of Visual Studio, loaded with all the useful tools in the developer’s kit (ReSharper and so on) and asked to, for example, analyze and improve a real piece of software. The same principles should apply when interviewing for a database positon. In addition to the usual questions challenging the candidate’s knowledge of such things as b-trees, object permissions, database recovery models, and so on, sit the candidate down with the other database developers or DBAs. Arm them with a copy of Management Studio, and a few other tools, then challenge them to discover the flaws in a stored procedure, and improve its performance. Or present them with a corrupt database and ask them to get the database back online, and discover the cause of the corruption.

• Windows Phone 7 Developer Tools - January 2011 Update

  - by Nikita Polyakov

  Long time no talk? So to make up for it, here is something very new – update to WP7 Dev Tools! The Windows Phone 7 Developer Tools January 2011 Update provides bits that you would install on TOP of the current WP7 Dev tools on your machine. If you are just installing the tools for the first time, this update replaces previously released October patch. In fact, it is no longer available as this January 2011 update replaces the patch entirely. What is in this update? TextBox support for Copy&Paste Updated Emulator Image that contains Copy&Paste for your testing There have been performance tweaks for the OS Minor Bugs and Fixes How does it Work? The Copy&Paste extends a existing TextBox control to have this new functionality, There is no current API access to the Clipboard or support for other controls that are not based on TextBox. If I have/Do I need to: A current application in the marketplace/No action is required Have an application that contains a TextBox in a Pivot or Panorama control surface/Text your application in provided emulator Recommendation is to move TextBox controls from directly top of controls that listen to Gesture movement to their own pop-off screens or entire pages as this might interfear with select behavior for Copy&Paste Have controls that do no inherit from TextBox/Such controls will not get new Copy&Paste behavior Note: The update materials, FAQ and Q&A do not answer WHEN the update for the OS will be sent to the phones.  Also to note - this update does NOT update your developer phone to enable Copy&Paste or any other features. Windows Phone 7 Training Kit February Update Windows Phone Training Kit has also been updated – you can grab a fresh copy here.   Where to I find more good information, documentation and training? This very awesome blog post from the Windows Phone Developer Blog - Windows Phone 7 Documentation Landscape. Official Blog Post on the Update is here. Happy coding! -Nikita   PS: I am well aware that it is Feb 4th and not January :) If you were disappointed at CES that Microsoft said nothing at all about future of WP7, don’t forget that MWC 2011 is Feb 14th – I am going to be listening for Windows Phone announcements then, as that is where the announcements were made about Windows Phone 7.

• How To Build An Enterprise Application - Introduction

  - by Tuan Nguyen

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