  • How many real world developers are involved with the Demoscene?

    - by spoulson
    I grew up learning to code based on what I've experienced with the demoscene. It seems to be a pretty sparse subculture in the US. How many developers watch or participate in the scene? Teaser: If you haven't checked out the scene before, take a look at one of my favorites: Debris by Farbrausch. Watch on demoscene.tv or download the app (179k) and run it yourself. No video, all realtime rendering and audio. Think, a small group of guys wrote this for a competition on their free time.

  • How do I get developers to look at our bug tracking page regularly?

    - by abeger
    We've recently started using Trac and are still trying to figure out the best way to use it in our environment. It's great, but it will only be effective if developers look at it once in a while and I'm trying to figure out how to instill that habit in them. I've contemplated several solutions, such as: forcing them to use Trac as their homepage (too draconian) handing out bookmarks to the RSS feeds (same problem--no one will look at them) automatic email notifications (won't drive them to the site and might just annoy them more than anything else) What are some other solutions? What have you tried that worked?

  • How much benefit do you get from working with other developers?

    - by SnOrfus
    For whatever reason I've only ever worked solo. The job that I have now, I was under the impression that I was being hired to work underneath a senior developer and that I'd be able to learn from them/their code. This was actually one of the conditions that I had when I accepted the position (that and I was broke and needed the cash - so I would have likely taken it anyway). As it turns out, the intention of management was for me to replace that senior developer because they were contracted and relatively expensive. The question I have is, though I've learned a lot in the 2 short years I've been here, am I potentially seriously stunting my learning/progress working solo instead of working at a company with other developers?

  • Developer’s Life – Every Developer is a Captain America

    - by Pinal Dave
    Captain America was first created as a comic book character in the 1940’s as a way to boost morale during World War II.  Aimed at a children’s audience, his legacy faded away when the war ended.  However, he has recently has a major reboot to become a popular movie character that deals with modern issues. When Captain America was first written, there was no such thing as a developer, programmer or a computer (the way we think of them, anyway).  Despite these limitations, I think there are still a lot of ways that modern Captain America is like modern developers. So how are developers like Captain America? Well, read on my list of reasons. Take on Big Projects Captain America isn’t afraid to take on big projects – and takes responsibility when the project is co-opted by the evil organization HYDRA.  Developers may not have super villains out there corrupting their work, but they know to keep on top of their projects and own what they do. Elderly Wisdom Steve Rogers, Captain America’s alter ego, was frozen in ice for decades, and brought back to life to solve problems. Developers can learn from this by respecting the opinions of their elders – technology is an ever-changing market, but the old-timers still have a few tricks up their sleeves! Don’t be Afraid of Change Don’t be afraid of change.  Captain America woke up to find the world he was accustomed to is now completely different.  He might have even felt his skills were no longer necessary.  He, and developers, know that everyone has their place in a team, though.  If you try your best, you will make it work. Fight Your Own Battle Sometimes you have to make it on your own.  Captain America is an integral part of the Avengers, but in his own movies, the other superheroes aren’t around to back him up.  Developers, too, must learn to work both within and with out a team. Solid Integrity One of Captain America’s greatest qualities is his integrity.  His determine to do what is right, keep his word, and act honestly earns him mockery from some of the less-savory characters – even “good guys” like Iron Man.  Developers, and everyone else, need to develop the strength of character to keep their integrity.  No matter your walk of life, there will be tempting obstacles.  Think of Captain America, and say “no.” There is a lot for all of us to learn from Captain America, to take away in our own lives, and admire in those who display it – I am specifically thinking of developers.  If you are enjoying this series as much as I am, please let me know who else you would like to see featured.

  • ViewStateMode in ASP.Net 4.0

    - by sreejukg
    When asp.net introduced the concept of viewstate, it changed the way how developers maintain the state for the controls in a web page. Until then to keep the track of the control(in classic asp), it was the developer responsibility to manually assign the posted content before rendering the control again. Viewstate made allowed the developer to do it with ease. The developers are not bothered about how controls keep there state on post back. Viewstate is rendered to the browser as a hidden variable __viewstate. Since viewstate stores the values of all controls, as the number of controls in the page increases, the content of viewstate grows large. It causes some websites to load slowly. As developers we need viewstate, but actually we do not want this for all the controls in the page. Till asp.net 3.5, if viewstate is disabled from web.config (using <pages viewstate=”false”/> ..</pages>), then you can not enable it from the control level/page level. Both <%@ Page EnableViewState=”true”…. and <asp:textbox EnableViewState=”true” will not work in this case. Lot of developers demands for more control over viewstate. It will be useful if the developers are able to disable it for the entire page and enable it for only those controls that needed viewstate. With ASP.NET 4.0, this is possible, a happy news for the developers. This is achieved by introducing a new property called ViewStateMode. Let us see, What is ViewStateMode – Is a new property in asp.net 4.0, that allows developers to enable viewstate for individual control even if the parent has disabled it. This ViewStateMode property can contain either of three values Enabled- Enable view state for the control even if the parent control has view state disabled. Disabled - Disable view state for this control even if the parent control has view state enabled Inherit - Inherit the value of ViewStateMode from the parent, this is the default value. To disable view state for a page and to enable it for a specific control on the page, you can set the EnableViewState property of the page to true, then set the ViewStateMode property of the page to Disabled, and then set the ViewStateMode property of the control to Enabled. Find the example below. Page directive - <%@ Page Language="C#"  EnableViewState="True" ViewStateMode="Disabled" .......... %> Code for the control  - <asp:TextBox runat="server" ViewStateMode="Enabled" ............../> Now the viewstate will be disabled for the whole page, but enabled for the TextBox. ViewStateMode gives developers more control over the viewstate.

  • Microsoft Introduces WebMatrix

    - by Rick Strahl
    originally published in CoDe Magazine Editorial Microsoft recently released the first CTP of a new development environment called WebMatrix, which along with some of its supporting technologies are squarely aimed at making the Microsoft Web Platform more approachable for first-time developers and hobbyists. But in the process, it also provides some updated technologies that can make life easier for existing .NET developers. Let’s face it: ASP.NET development isn’t exactly trivial unless you already have a fair bit of familiarity with sophisticated development practices. Stick a non-developer in front of Visual Studio .NET or even the Visual Web Developer Express edition and it’s not likely that the person in front of the screen will be very productive or feel inspired. Yet other technologies like PHP and even classic ASP did provide the ability for non-developers and hobbyists to become reasonably proficient in creating basic web content quickly and efficiently. WebMatrix appears to be Microsoft’s attempt to bring back some of that simplicity with a number of technologies and tools. The key is to provide a friendly and fully self-contained development environment that provides all the tools needed to build an application in one place, as well as tools that allow publishing of content and databases easily to the web server. WebMatrix is made up of several components and technologies: IIS Developer Express IIS Developer Express is a new, self-contained development web server that is fully compatible with IIS 7.5 and based on the same codebase that IIS 7.5 uses. This new development server replaces the much less compatible Cassini web server that’s been used in Visual Studio and the Express editions. IIS Express addresses a few shortcomings of the Cassini server such as the inability to serve custom ISAPI extensions (i.e., things like PHP or ASP classic for example), as well as not supporting advanced authentication. IIS Developer Express provides most of the IIS 7.5 feature set providing much better compatibility between development and live deployment scenarios. SQL Server Compact 4.0 Database access is a key component for most web-driven applications, but on the Microsoft stack this has mostly meant you have to use SQL Server or SQL Server Express. SQL Server Compact is not new-it’s been around for a few years, but it’s been severely hobbled in the past by terrible tool support and the inability to support more than a single connection in Microsoft’s attempt to avoid losing SQL Server licensing. The new release of SQL Server Compact 4.0 supports multiple connections and you can run it in ASP.NET web applications simply by installing an assembly into the bin folder of the web application. In effect, you don’t have to install a special system configuration to run SQL Compact as it is a drop-in database engine: Copy the small assembly into your BIN folder (or from the GAC if installed fully), create a connection string against a local file-based database file, and then start firing SQL requests. Additionally WebMatrix includes nice tools to edit the database tables and files, along with tools to easily upsize (and hopefully downsize in the future) to full SQL Server. This is a big win, pending compatibility and performance limits. In my simple testing the data engine performed well enough for small data sets. This is not only useful for web applications, but also for desktop applications for which a fully installed SQL engine like SQL Server would be overkill. Having a local data store in those applications that can potentially be accessed by multiple users is a welcome feature. ASP.NET Razor View Engine What? Yet another native ASP.NET view engine? We already have Web Forms and various different flavors of using that view engine with Web Forms and MVC. Do we really need another? Microsoft thinks so, and Razor is an implementation of a lightweight, script-only view engine. Unlike the Web Forms view engine, Razor works only with inline code, snippets, and markup; therefore, it is more in line with current thinking of what a view engine should represent. There’s no support for a “page model” or any of the other Web Forms features of the full-page framework, but just a lightweight scripting engine that works with plain markup plus embedded expressions and code. The markup syntax for Razor is geared for minimal typing, plus some progressive detection of where a script block/expression starts and ends. This results in a much leaner syntax than the typical ASP.NET Web Forms alligator (<% %>) tags. Razor uses the @ sign plus standard C# (or Visual Basic) block syntax to delineate code snippets and expressions. Here’s a very simple example of what Razor markup looks like along with some comment annotations: <!DOCTYPE html> <html>     <head>         <title></title>     </head>     <body>     <h1>Razor Test</h1>          <!-- simple expressions -->     @DateTime.Now     <hr />     <!-- method expressions -->     @DateTime.Now.ToString("T")          <!-- code blocks -->     @{         List<string> names = new List<string>();         names.Add("Rick");         names.Add("Markus");         names.Add("Claudio");         names.Add("Kevin");     }          <!-- structured block statements -->     <ul>     @foreach(string name in names){             <li>@name</li>     }     </ul>           <!-- Conditional code -->        @if(true) {                        <!-- Literal Text embedding in code -->        <text>         true        </text>;    }    else    {        <!-- Literal Text embedding in code -->       <text>       false       </text>;    }    </body> </html> Like the Web Forms view engine, Razor parses pages into code, and then executes that run-time compiled code. Effectively a “page” becomes a code file with markup becoming literal text written into the Response stream, code snippets becoming raw code, and expressions being written out with Response.Write(). The code generated from Razor doesn’t look much different from similar Web Forms code that only uses script tags; so although the syntax may look different, the operational model is fairly similar to the Web Forms engine minus the overhead of the large Page object model. However, there are differences: -Razor pages are based on a new base class, Microsoft.WebPages.WebPage, which is hosted in the Microsoft.WebPages assembly that houses all the Razor engine parsing and processing logic. Browsing through the assembly (in the generated ASP.NET Temporary Files folder or GAC) will give you a good idea of the functionality that Razor provides. If you look closely, a lot of the feature set matches ASP.NET MVC’s view implementation as well as many of the helper classes found in MVC. It’s not hard to guess the motivation for this sort of view engine: For beginning developers the simple markup syntax is easier to work with, although you obviously still need to have some understanding of the .NET Framework in order to create dynamic content. The syntax is easier to read and grok and much shorter to type than ASP.NET alligator tags (<% %>) and also easier to understand aesthetically what’s happening in the markup code. Razor also is a better fit for Microsoft’s vision of ASP.NET MVC: It’s a new view engine without the baggage of Web Forms attached to it. The engine is more lightweight since it doesn’t carry all the features and object model of Web Forms with it and it can be instantiated directly outside of the HTTP environment, which has been rather tricky to do for the Web Forms view engine. Having a standalone script parser is a huge win for other applications as well – it makes it much easier to create script or meta driven output generators for many types of applications from code/screen generators, to simple form letters to data merging applications with user customizability. For me personally this is very useful side effect and who knows maybe Microsoft will actually standardize they’re scripting engines (die T4 die!) on this engine. Razor also better fits the “view-based” approach where the view is supposed to be mostly a visual representation that doesn’t hold much, if any, code. While you can still use code, the code you do write has to be self-contained. Overall I wouldn’t be surprised if Razor will become the new standard view engine for MVC in the future – and in fact there have been announcements recently that Razor will become the default script engine in ASP.NET MVC 3.0. Razor can also be used in existing Web Forms and MVC applications, although that’s not working currently unless you manually configure the script mappings and add the appropriate assemblies. It’s possible to do it, but it’s probably better to wait until Microsoft releases official support for Razor scripts in Visual Studio. Once that happens, you can simply drop .cshtml and .vbhtml pages into an existing ASP.NET project and they will work side by side with classic ASP.NET pages. WebMatrix Development Environment To tie all of these three technologies together, Microsoft is shipping WebMatrix with an integrated development environment. An integrated gallery manager makes it easy to download and load existing projects, and then extend them with custom functionality. It seems to be a prominent goal to provide community-oriented content that can act as a starting point, be it via a custom templates or a complete standard application. The IDE includes a project manager that works with a single project and provides an integrated IDE/editor for editing the .cshtml and .vbhtml pages. A run button allows you to quickly run pages in the project manager in a variety of browsers. There’s no debugging support for code at this time. Note that Razor pages don’t require explicit compilation, so making a change, saving, and then refreshing your page in the browser is all that’s needed to see changes while testing an application locally. It’s essentially using the auto-compiling Web Project that was introduced with .NET 2.0. All code is compiled during run time into dynamically created assemblies in the ASP.NET temp folder. WebMatrix also has PHP Editing support with syntax highlighting. You can load various PHP-based applications from the WebMatrix Web Gallery directly into the IDE. Most of the Web Gallery applications are ready to install and run without further configuration, with Wizards taking you through installation of tools, dependencies, and configuration of the database as needed. WebMatrix leverages the Web Platform installer to pull the pieces down from websites in a tight integration of tools that worked nicely for the four or five applications I tried this out on. Click a couple of check boxes and fill in a few simple configuration options and you end up with a running application that’s ready to be customized. Nice! You can easily deploy completed applications via WebDeploy (to an IIS server) or FTP directly from within the development environment. The deploy tool also can handle automatically uploading and installing the database and all related assemblies required, making deployment a simple one-click install step. Simplified Database Access The IDE contains a database editor that can edit SQL Compact and SQL Server databases. There is also a Database helper class that facilitates database access by providing easy-to-use, high-level query execution and iteration methods: @{       var db = Database.OpenFile("FirstApp.sdf");     string sql = "select * from customers where Id > @0"; } <ul> @foreach(var row in db.Query(sql,1)){         <li>@row.FirstName @row.LastName</li> } </ul> The query function takes a SQL statement plus any number of positional (@0,@1 etc.) SQL parameters by simple values. The result is returned as a collection of rows which in turn have a row object with dynamic properties for each of the columns giving easy (though untyped) access to each of the fields. Likewise Execute and ExecuteNonQuery allow execution of more complex queries using similar parameter passing schemes. Note these queries use string-based queries rather than LINQ or Entity Framework’s strongly typed LINQ queries. While this may seem like a step back, it’s also in line with the expectations of non .NET script developers who are quite used to writing and using SQL strings in code rather than using OR/M frameworks. The only question is why was something not included from the beginning in .NET and Microsoft made developers build custom implementations of these basic building blocks. The implementation looks a lot like a DataTable-style data access mechanism, but to be fair, this is a common approach in scripting languages. This type of syntax that uses simple, static, data object methods to perform simple data tasks with one line of code are common in scripting languages and are a good match for folks working in PHP/Python, etc. Seems like Microsoft has taken great advantage of .NET 4.0’s dynamic typing to provide this sort of interface for row iteration where each row has properties for each field. FWIW, all the examples demonstrate using local SQL Compact files - I was unable to get a SQL Server connection string to work with the Database class (the connection string wasn’t accepted). However, since the code in the page is still plain old .NET, you can easily use standard ADO.NET code or even LINQ or Entity Framework models that are created outside of WebMatrix in separate assemblies as required. The good the bad the obnoxious - It’s still .NET The beauty (or curse depending on how you look at it :)) of Razor and the compilation model is that, behind it all, it’s still .NET. Although the syntax may look foreign, it’s still all .NET behind the scenes. You can easily access existing tools, helpers, and utilities simply by adding them to the project as references or to the bin folder. Razor automatically recognizes any assembly reference from assemblies in the bin folder. In the default configuration, Microsoft provides a host of helper functions in a Microsoft.WebPages assembly (check it out in the ASP.NET temp folder for your application), which includes a host of HTML Helpers. If you’ve used ASP.NET MVC before, a lot of the helpers should look familiar. Documentation at the moment is sketchy-there’s a very rough API reference you can check out here: http://www.asp.net/webmatrix/tutorials/asp-net-web-pages-api-reference Who needs WebMatrix? Uhm… good Question Clearly Microsoft is trying hard to create an environment with WebMatrix that is easy to use for newbie developers. The goal seems to be simplicity in providing a minimal development environment and an easy-to-use script engine/language that makes it easy to get started with. There’s also some focus on community features that can be used as starting points, such as Web Gallery applications and templates. The community features in particular are very nice and something that would be nice to eventually see in Visual Studio as well. The question is whether this is too little too late. Developers who have been clamoring for a simpler development environment on the .NET stack have mostly left for other simpler platforms like PHP or Python which are catering to the down and dirty developer. Microsoft will be hard pressed to win those folks-and other hardcore PHP developers-back. Regardless of how much you dress up a script engine fronted by the .NET Framework, it’s still the .NET Framework and all the complexity that drives it. While .NET is a fine solution in its breadth and features once you get a basic handle on the core features, the bar of entry to being productive with the .NET Framework is still pretty high. The MVC style helpers Microsoft provides are a good step in the right direction, but I suspect it’s not enough to shield new developers from having to delve much deeper into the Framework to get even basic applications built. Razor and its helpers is trying to make .NET more accessible but the reality is that in order to do useful stuff that goes beyond the handful of simple helpers you still are going to have to write some C# or VB or other .NET code. If the target is a hobby/amateur/non-programmer the learning curve isn’t made any easier by WebMatrix it’s just been shifted a tad bit further along in your development endeavor when you run out of canned components that are supplied either by Microsoft or the community. The database helpers are interesting and actually I’ve heard a lot of discussion from various developers who’ve been resisting .NET for a really long time perking up at the prospect of easier data access in .NET than the ridiculous amount of code it takes to do even simple data access with raw ADO.NET. It seems sad that such a simple concept and implementation should trigger this sort of response (especially since it’s practically trivial to create helpers like these or pick them up from countless libraries available), but there it is. It also shows that there are plenty of developers out there who are more interested in ‘getting stuff done’ easily than necessarily following the latest and greatest practices which are overkill for many development scenarios. Sometimes it seems that all of .NET is focused on the big life changing issues of development, rather than the bread and butter scenarios that many developers are interested in to get their work accomplished. And that in the end may be WebMatrix’s main raison d'être: To bring some focus back at Microsoft that simpler and more high level solutions are actually needed to appeal to the non-high end developers as well as providing the necessary tools for the high end developers who want to follow the latest and greatest trends. The current version of WebMatrix hits many sweet spots, but it also feels like it has a long way to go before it really can be a tool that a beginning developer or an accomplished developer can feel comfortable with. Although there are some really good ideas in the environment (like the gallery for downloading apps and components) which would be a great addition for Visual Studio as well, the rest of the development environment just feels like crippleware with required functionality missing especially debugging and Intellisense, but also general editor support. It’s not clear whether these are because the product is still in an early alpha release or whether it’s simply designed that way to be a really limited development environment. While simple can be good, nobody wants to feel left out when it comes to necessary tool support and WebMatrix just has that left out feeling to it. If anything WebMatrix’s technology pieces (which are really independent of the WebMatrix product) are what are interesting to developers in general. The compact IIS implementation is a nice improvement for development scenarios and SQL Compact 4.0 seems to address a lot of concerns that people have had and have complained about for some time with previous SQL Compact implementations. By far the most interesting and useful technology though seems to be the Razor view engine for its light weight implementation and it’s decoupling from the ASP.NET/HTTP pipeline to provide a standalone scripting/view engine that is pluggable. The first winner of this is going to be ASP.NET MVC which can now have a cleaner view model that isn’t inconsistent due to the baggage of non-implemented WebForms features that don’t work in MVC. But I expect that Razor will end up in many other applications as a scripting and code generation engine eventually. Visual Studio integration for Razor is currently missing, but is promised for a later release. The ASP.NET MVC team has already mentioned that Razor will eventually become the default MVC view engine, which will guarantee continued growth and development of this tool along those lines. And the Razor engine and support tools actually inherit many of the features that MVC pioneered, so there’s some synergy flowing both ways between Razor and MVC. As an existing ASP.NET developer who’s already familiar with Visual Studio and ASP.NET development, the WebMatrix IDE doesn’t give you anything that you want. The tools provided are minimal and provide nothing that you can’t get in Visual Studio today, except the minimal Razor syntax highlighting, so there’s little need to take a step back. With Visual Studio integration coming later there’s little reason to look at WebMatrix for tooling. It’s good to see that Microsoft is giving some thought about the ease of use of .NET as a platform For so many years, we’ve been piling on more and more new features without trying to take a step back and see how complicated the development/configuration/deployment process has become. Sometimes it’s good to take a step - or several steps - back and take another look and realize just how far we’ve come. WebMatrix is one of those reminders and one that likely will result in some positive changes on the platform as a whole. © Rick Strahl, West Wind Technologies, 2005-2010Posted in ASP.NET   IIS7

  • What to do when opensource project starts to tear apart? (or a manager tries to write code and than shouts at the team)

    - by Kabumbus
    Imagine there is an open source cross-platform project on Google code. It has lots of revisions (1000). It concentrates in itself lots technological stuff - rare stuff - it mixes top tech. It contains server, and more than one client. The project was created by a well-connected team of developers (friends) and a manager that was sponsoring project at its start up during its first few months (project now is more than a year old-sponsoring oss project is a big good deal- also gave the idea of project to developers). The project was growing in complexity and effort reqiered to continue development. Once upon a time a manager - team leader started trying to write code (he was a programmer in some other projects - not the best, but he felt like he was one). He started because one of the developers suggested an idea at the team meeting and he felt he just needed to do it on his own. He failed, and he told the dev team about it. The dev team did what he failed to do in a few days. After that, the manager feels that team codes with out him perfectly and gets the job done in short time. He felt sorry and lost and he started to crash like an old bad PC. Firstly, he started to scream (in forms of messages not in voice) he tried to tell developers that what they were doing was a bad, not-needed thing - developers kindly told him that his "beginnings" were not compilable while dev team product worked as needed. He told the developers that all work they do should be firstly discussed with him. Here is the part where we need to mention that all team members are "project owners" and logically have equal rights. The team leader suggested to the developers these options: change their dev process to go through him, or be moved from project owners to contributers. So what are our options as developers? What arguments we can provide to the team leader/manager for him to calm down? Is it possible to save the project or is it better to fork out now? An important issue is that lately we had no active ticket system, and I personally think that this was the reason the mess appeared. So... any ideas?

  • What is your company's stance on Developers using Laptops?

    - by codepunk
    I am a developer and my company is moving towards a "no laptop" policy in fear of them being lost or stolen and source code being compromised. Now I don't work for NASA, the military or anything labeled Top Secret but our code is very important to our business nonetheless (as all source code would be). I'll be honest, I disagree with this policy against laptops and wanted to see what others think. I'd like to know: What is your team/company's stance on laptops Your company's size and/or field (small, medium or large, Fortune 500, etc). Whether you've had to take any extra precautions (signing any additional legal, ensure your hard drive is encrypted, etc). Thanks!

  • Agile team with no dedicated Tester members. Insane or efficient?

    - by MetaFight
    I'm a software developer. I've been thinking a lot about the efficiency of the Software Testers I've worked with so far in my career. In fact, I've been thinking a lot about the Software Testers role in general and have reached a potentially contentious conclusion: Non-developer Software Testers staff are less efficient at software testing than developers. Now, before everyone gets upset, hear me out. This isn't mere opinion: Software Testing and Software Development both require a lot of skills in common: Problem solving Thinking about corner cases Analytical skills The ability to define clear and concise step-by-step scenarios What developers have in addition to this is the ability to automate their tests. Yes, I know non-dev testers can automate their tests too, but that often then becomes a test maintenance issue. Because automating UI tests is essentially programming, non-dev members encounter all the same difficulties software developers encounter: Copy-pasta, lack of code reusibility/maintainability, etc. So, I was wondering. Why not replace all non-dev roles with developer roles? Developers have the skills required to perform Software Testing tasks, and they have the skills to automate tests and keep them maintainable. Would the following work: Hire a bunch of developers and split them into 2 roles: Software developers Software developers doing testing (some manual, mostly automated by writing integration tests, unit tests, etc) Software developers doing application support. (I've removed this as it is probably a separate question altogether) And, in our case since we're doing Agile development, rotate the roles every sprint or two. Also, if at all possible, try to have people spend their Developer stints and Testing stints on different projects. Ideally you would want to reduce the turnover rate per rotation. So maybe you could have 2 groups and make sure the rotation cycles of the groups are elided. So, for example, if each rotation was two sprints long, the two groups would have their rotations 1 sprint apart. That way there's only a 50% turn-over rate per sprint. Am I crazy, or could this work? (Obviously a key component to this working is that all devs want to be in the 3 roles. Let's assume I'm starting a new company and I can hire these ideal people) Edit I've removed the phrase "QA", as apparently we are using it incorrectly where I work.

  • How are developers using source control, I am trying to find the most efficient way to do source con

    - by RJ
    I work in a group of 4 .Net developers. We rarely work on the same project at the same time but it does happen from time to time.We use TFS for source control. My most recent example is a project I just placed into production last night that included 2 WCF services and a web application front end. I worked out of a branch called "prod" because the application is brand new and has never seen the light of day. Now that the project is live, I need to branch off the prod branch for features, bugs, etc... So what is the best way to do this? Do I simple create a new branch and sort of archive the old branch and never use it again? Do I branch off and then merge my branch changes back into the prod branch when I want to deploy to production? And what about the file and assembly version. They are currently at 1.0.0.0. When do they change and why? If I fix a small bug, which number changes if any? If I add a feature, which number changes if any? What I am looking for is what you have found to be the best way to efficiently manage source control. Most places I have worked always seem to bang heads with the source control system in on way or another and I would just like to find out what you have found that works the best.

  • When may I ask a question to fellow developers? (Rules before asking questions).

    I assigned a quite simple task to one junior developer today, and he kept pinging me EVERY 5 minutes for HOURS, asking STEP BY STEP, what to do. Whenever something went wrong, he simply copy&pasted the log and basically wrote, "An exception occurred. What should I do?" So I finally had to tell him, "If you want to be a developer, please start thinking a little bit. Read the error message. That's what they are for!". I also however, tell junior developers to ask questions before spending too much time trying to solve it themselves. This might sound contradictory, but I feel there is some kind of an implicit rule that distinguishes questions that should be asked fairly quickly and that should not (and I try to follow those rules when I ask questions..) So my question is, do you have any rules that you follow, or expect others to follow on asking questions? If so, what are they? Let me start with my own. If you have struggled for more than 90 min, you may ask that question (exceptions exists). If you haven't struggled for more than 15 min, you may not ask that question (if you are sure that the answer can not be found within 15 min, this rule does not have to apply). If it is completely out of your domain and you do not plan to learn that domain, you may ask that question after 15 min (e.g. if I am a java programmer and need to back up the DB, I may ask the DBA what procedure to follow after googling for 15 min). If it is a "local" question, whose answer is difficult to derive or for which resources is difficult to get (e.g. asking an colleague "what method xxx does" etc.), you may ask that question after 15 min. If the answer for it is difficult to derive, and you know that the other person knows the answer, you may ask the question after 15 min (e.g. asking a hibernate expert "What do I need to change else to make this work?". If the process to derive the answer is interesting and is a good learning opportunity, you may ask for hints but you may not ask for answers! What are your rules?

  • Running Windows Phone Developers Tools CTP under VMWare Player - Yes you can! - But do you want to?

    - by Liam Westley
    This blog is the result of a quick investigation of running the Windows Phone Developer Tools CTP under VMWare Player.  In the release notes for Windows Phone Developer Tools CTP it mentions that it is not supported under VirtualPC or Hyper-V.  Some developers have policies where ‘no non-production code’ can be installed on their development workstation and so the only way they can use a CTP like this is in a virtual machine. The dilemma here is that the emulator for Windows Phone itself is a virtual machine and running a virtual machine within another virtual machine is normally frowned upon.  Even worse, previous Windows Mobile emulators detected they were in a virtual machine and refused to run.  Why VMWare? I selected VMWare as a possible solution as it is possible to run VMWare ESXi under VMWare Workstation by manually setting configuration options in the VMX configuration file so that it does not detect the presence of a virtual environment. I actually found that I could use VMWare Player (the free version, that can now create VM images) and that there was no need for any editing of the configuration file (I tried various switches, none of which made any difference to performance). So you can run the CTP under VMWare Player, that’s the good news. The bad news is that it is incredibly slow, bordering on unusable.  However, if it’s the only way you can use the CTP, at least this is an option. VMWare Player configuration I used the latest VMWare Player, 3.0, running under Windows x64 on my HP 6910p laptop with an Intel T7500 Dual Core CPU running at 2.2GHz, 4Gb of memory and using a separate drive for the virtual machines. I created a machine in VMWare Player with a single CPU, 1536 Mb memory and installed Windows 7 x64 from an ISO image.  I then performed a Windows Update, installed VMWare Tools, and finally the Windows Phone Developer Tools CTP After a few warnings about performance, I configured Windows 7 to run with Windows 7 Basic theme rather than use Aero (which is available under VMWare Player as it has a WDDM driver). Timings As a test I first launched Microsoft Visual Studio 2010 Express for Windows Phone, and created a default Windows Phone Application project.  I then clicked the run button, which starts the emulator and then loads the default application onto the emulator. For the second test I left the emulator running, stopped the default application, added a single button to change the page title and redeployed to the already running emulator by clicking the run button.   Test 1 (1st run) Test 2 (emulator already running)   VMWare Player 10 minutes  1 minute   Windows x64 native 1 minute  < 10 seconds   Conclusion You can run the Windows Phone Developer Tools CTP under VMWare Player, but it’s really, really slow and you would have to have very good reasons to try this approach. If you need to keep a development system free of non production code, and the two systems aren’t required to run simultaneously, then I’d consider a boot from VHD option.  Then you can completely isolate the Windows Phone Developer Tools CTP and development environment into a single VHD separate from your main development system.

  • Career development as a Software Developer without becoming a manager.

    - by albertpascual
    I’m a developer, I like to write new exciting code everyday, my perfect day at work is a day that when I wake up, I know that I have to write some code that I haven’t done before or to use a new framework/language/platform that is unknown to me. The best days in the office is when a project is waiting for me to architect or write. In my 15 years in the development field, I had to in order to get a better salary to manage people, not just to lead developers, to actually manage people. Something that I found out when I get into a management position is that I’m not that good at managing people, and not afraid to say it. I do not enjoy that part of the job, the worse one, takes time away from what I really like. Leading developers and managing people are very different things. I do like teaching and leading developers in a project. Yet most people believe, and is true in most companies, the way to get a better salary is to be promoted to a manager position. In order to advance in your career you need to let go of the everyday writing code and become a supervisor or manager. This is the path for developers after they become senior developers. As you get older and your family grows, the only way to hit your salary requirements is to advance your career to become a manager and get that manager salary. That path is the common in most companies, the most intelligent companies out there, have learned that promoting good developers mean getting a crappy manager and losing a good resource. Now scratch everything I said, because as I previously stated, I don’t see myself going to the office everyday and just managing people until is time to go home. I like to spend hours working in some code to accomplish a task, learning new platforms and languages or patterns to existing languages. Being interrupted every 15 minutes by emails or people stopping by my office to resolve their problems, is not something I could enjoy. All the sudden riding my motorcycle to work one cold morning over the Redlands Canyon and listening to .NET Rocks podcast, Michael “Doc” Norton explaining how to take control of your development career without necessary going to the manager’s track. I know, I should not have headphones under my helmet when riding a motorcycle in California. His conversation with Carl Franklin and Richard Campbell was just confirming everything I have ever did with actually more details and assuring that there are other paths. His method was simple yet most of us, already do many of those steps, Mr. Michael “Doc” Norton believe that it pays off on the long run, that finally companies prefer to pay higher salaries to those developers, yet I would actually think that many companies do not see developers that way, this is not true for bigger companies. However I do believe the value of those developers increase and most of the time, changing companies could increase their salary instead of staying in the same one. In short without even trying to get into the shadow of Mr. Norton and without following the steps in the order; you should love to learn new technologies, and then teach them to other geeks. I personally have learn many technologies and I haven’t stop doing that, I am a professor at UCR where I teach ASP.NET and Silverlight. Mr Norton continues that after than, you want to be involve in the development community, user groups, online forums, open source projects. I personally talk to user groups, I’m very active in forums asking and answering questions as well as for those I got awarded the Microsoft MVP for ASP.NET. After you accomplish all those, you should also expose yourself for what you know and what you do not know, learning a new language will make you humble again as well as extremely happy. There is no better feeling that learning a new language or pattern in your daily job. If you love your job everyday and what you do, I really recommend you to follow Michael’s presentation that he kindly share it on the link below. His confirmation is a refreshing, knowing that my future is not behind a desk where the computer screen is on my right hand side instead of in front of me. Where I don’t have to spent the days filling up performance forms for people and the new platforms that I haven’t been using yet are just at my fingertips. Presentation here. http://www.slideshare.net/LeanDog/take-control-of-your-development-career-michael-doc-norton?from=share_email_logout3 Take Control of Your Development Career Welcome!

Michael “Doc” Norton @DocOnDev http://docondev.blogspot.com/ [email protected] In a short summary, I recommend any developer to check his blog and more important his presentation, I haven’t been lucky enough to watch him live, I’m looking forward the day I have the opportunity. He is giving us hope in the future of developers, when I see some of my geek friends moving to position that in short years they begin to regret, I get more unsure of my future doing what I love. I would say that now is looking at the spectrum of companies that understand and appreciate developers. There are a few there, hopefully with time code sweat shops will start disappearing and being a developer will feed a family of 4.

  • Curing the Database-Application mismatch

    - by Phil Factor
    If an application requires access to a database, then you have to be able to deploy it so as to be version-compatible with the database, in phase. If you can deploy both together, then the application and database must normally be deployed at the same version in which they, together, passed integration and functional testing.  When a single database supports more than one application, then the problem gets more interesting. I’ll need to be more precise here. It is actually the application-interface definition of the database that needs to be in a compatible ‘version’.  Most databases that get into production have no separate application-interface; in other words they are ‘close-coupled’.  For this vast majority, the whole database is the application-interface, and applications are free to wander through the bowels of the database scot-free.  If you’ve spurned the perceived wisdom of application architects to have a defined application-interface within the database that is based on views and stored procedures, any version-mismatch will be as sensitive as a kitten.  A team that creates an application that makes direct access to base tables in a database will have to put a lot of energy into keeping Database and Application in sync, to say nothing of having to tackle issues such as security and audit. It is not the obvious route to development nirvana. I’ve been in countless tense meetings with application developers who initially bridle instinctively at the apparent restrictions of being ‘banned’ from the base tables or routines of a database.  There is no good technical reason for needing that sort of access that I’ve ever come across.  Everything that the application wants can be delivered via a set of views and procedures, and with far less pain for all concerned: This is the application-interface.  If more than zero developers are creating a database-driven application, then the project will benefit from the loose-coupling that an application interface brings. What is important here is that the database development role is separated from the application development role, even if it is the same developer performing both roles. The idea of an application-interface with a database is as old as I can remember. The big corporate or government databases generally supported several applications, and there was little option. When a new application wanted access to an existing corporate database, the developers, and myself as technical architect, would have to meet with hatchet-faced DBAs and production staff to work out an interface. Sure, they would talk up the effort involved for budgetary reasons, but it was routine work, because it decoupled the database from its supporting applications. We’d be given our own stored procedures. One of them, I still remember, had ninety-two parameters. All database access was encapsulated in one application-module. If you have a stable defined application-interface with the database (Yes, one for each application usually) you need to keep the external definitions of the components of this interface in version control, linked with the application source,  and carefully track and negotiate any changes between database developers and application developers.  Essentially, the application development team owns the interface definition, and the onus is on the Database developers to implement it and maintain it, in conformance.  Internally, the database can then make all sorts of changes and refactoring, as long as source control is maintained.  If the application interface passes all the comprehensive integration and functional tests for the particular version they were designed for, nothing is broken. Your performance-testing can ‘hang’ on the same interface, since databases are judged on the performance of the application, not an ‘internal’ database process. The database developers have responsibility for maintaining the application-interface, but not its definition,  as they refactor the database. This is easily tested on a daily basis since the tests are normally automated. In this setting, the deployment can proceed if the more stable application-interface, rather than the continuously-changing database, passes all tests for the version of the application. Normally, if all goes well, a database with a well-designed application interface can evolve gracefully without changing the external appearance of the interface, and this is confirmed by integration tests that check the interface, and which hopefully don’t need to be altered at all often.  If the application is rapidly changing its ‘domain model’  in the light of an increased understanding of the application domain, then it can change the interface definitions and the database developers need only implement the interface rather than refactor the underlying database.  The test team will also have to redo the functional and integration tests which are, of course ‘written to’ the definition.  The Database developers will find it easier if these tests are done before their re-wiring  job to implement the new interface. If, at the other extreme, an application receives no further development work but survives unchanged, the database can continue to change and develop to keep pace with the requirements of the other applications it supports, and needs only to take care that the application interface is never broken. Testing is easy since your automated scripts to test the interface do not need to change. The database developers will, of course, maintain their own source control for the database, and will be likely to maintain versions for all major releases. However, this will not need to be shared with the applications that the database servers. On the other hand, the definition of the application interfaces should be within the application source. Changes in it have to be subject to change-control procedures, as they will require a chain of tests. Once you allow, instead of an application-interface, an intimate relationship between application and database, we are in the realms of impedance mismatch, over and above the obvious security problems.  Part of this impedance problem is a difference in development practices. Whereas the application has to be regularly built and integrated, this isn’t necessarily the case with the database.  An RDBMS is inherently multi-user and self-integrating. If the developers work together on the database, then a subsequent integration of the database on a staging server doesn’t often bring nasty surprises. A separate database-integration process is only needed if the database is deliberately built in a way that mimics the application development process, but which hampers the normal database-development techniques.  This process is like demanding a official walking with a red flag in front of a motor car.  In order to closely coordinate databases with applications, entire databases have to be ‘versioned’, so that an application version can be matched with a database version to produce a working build without errors.  There is no natural process to ‘version’ databases.  Each development project will have to define a system for maintaining the version level. A curious paradox occurs in development when there is no formal application-interface. When the strains and cracks happen, the extra meetings, bureaucracy, and activity required to maintain accurate deployments looks to IT management like work. They see activity, and it looks good. Work means progress.  Management then smile on the design choices made. In IT, good design work doesn’t necessarily look good, and vice versa.

  • Ldap access lists users even if user has no rights...

    - by Patkos Csaba
    I am trying to set up a more complex Active Directory structure for some testing purposes. What I did so far: set up 2 windows (one 2008 and one 2003) to control the same domain set up an Organizational Unit (ou): Developers set up 2 child OUs: "one" and "two" each OU has it's admin: adminOne and adminTwo I denied all access to OU "two" by removing on the Security tab all the groups I don't want to access it. now, when I log in as adminOne and I try to click on OU "two" it says I don't have permissions to see the users and properties of "two" - this is perfect, it's what I want Here comes my problem: I do a LDAP query with the adminOne user on the "Developers" What I expect to happen: I expect to retrieve the users from Developer - One I expect to NOT be able to retrieve the users from Developers - Two What actually happens: ldap shows all the users, both from Developers - One and Developers - Two, even if the user should not have permissions to Developers - Two And now my question: is there any specific settings on Windows 2003 or 2008 Active Directory servers which allow or deny access over LDAP? I could not find any.

  • Just released: a new SEO extension for the ASP.NET MVC routing engine

    - by efran.cobisi
    Dear users,after several months of hard work, we are proud to announce to the world that Cobisi's new SEO routing engine for ASP.NET MVC has been officially released! We even provide a free edition which comes at no cost, so this is something you can't really miss if you are a serious ASP.NET developer. ;)SEO routes for ASP.NET MVCCobisi SEO Extensions - this is the name of the product - is an advanced tool for software developers that allows to optimize ASP.NET MVC web applications and sites for search engines. It comes with a powerful routing engine, which extends the standard ASP.NET routing module to provide a much more flexible way to define search optimized routes, and a complete set of classes that make customizing the entire routing infrastructure very easy and cool.In its simplest form, defining a route for an MVC action is just a matter of decorating the method with the [Route("...")] attribute and specifying the desired URL. The library will take care of the rest and set up the route accordingly; while coding routes this way, Cobisi SEO Extensions also shows how the final routes will be, without leaving the Visual Studio IDE!Manage MVC routes with easeIn fact, Cobisi SEO Extensions integrates with the Visual Studio IDE to offer a large set of time-saving improvements targeted at ASP.NET developers. A new tool window, for example, allows to easily browse among the routes exposed by your applications, being them standard ASP.NET routes, MVC specific routes or SEO routes. The routes can be easily filtered on the fly, to ease finding the ones you are interested in. Double clicking a SEO route will even open the related ASP.NET MVC controller, at the beginning of the specified action method.In addition to that, Cobisi SEO Extensions allows to easily understand how each SEO route is composed by showing the routing model details directly in the IDE, beneath each MVC action route.Furthermore, Cobisi SEO Extensions helps developers to easily recognize which class is an MVC controller and which methods is an MVC action by drawing a special dashed underline mark under each items of these categories.Developers, developers, developers, ...We are really eager to receive your feedback and suggestions - please feel free to ping us with your comments! Thank you! Cheers! -- Efran Cobisi Cobisi lead developer Microsoft MVP, MCSD, MCAD, MCTS: SQL Server 2005, MCP

  • Oracle’s Java Community Outreach Plan

    - by Yolande Poirier
    As the steward of Java, Oracle recognizes the importance and value of the Java community, and the relevant role it plays in keeping Java the largest, most vibrant developer community in the world.   In order to increase Oracle’s touch with Java developers worldwide, we are shifting our focus from a flagship JavaOne event followed by several regional JavaOne conferences, to a new outreach model which continues with the JavaOne flagship event, as well as a mix of online content, regional Java Tours, and regional 3rd party event participation.  1. JavaOne JavaOne continues to remain the premier hub for Java developers where you are given the opportunity to improve your Java technical skills, and interact with other members of the Java community. JavaOne is centered on open collaboration and sharing, and Oracle will continue to invest in JavaOne as a unique stand-alone event for the Java community. Oracle recognizes that many developers cannot attend JavaOne in person, therefore Oracle will share the wealth of the unique event material to those developers through a new and easy-to-access online Java program. While online JavaOne content cannot address the importance of actual face-to-face community/developer engagements and networking, online content does aide in extending the Java technical learning opportunity to a broader collection of developers. 2. Java Developer Day Tours Oracle will execute regional Java Developer Days with recognized Java User Groups (JUGs) with participation from Java Evangelist and Java Champions. This allows local, regional specific Java topics to be addressed both by Oracle and the Java community. In addition, Oracle will deliver more virtual technical content programs to reach developers where an existing JUG may not have a presence. 3. Sponsorship of Community-Driven Regional Events/Conferences Oracle also recognizes that improved community dialog and relations are achievable by continued Oracle sponsorship and onsite participation at both established/well-recognized 3rd party events and new emerging/growing 3rd party events. Oracle’s ultimate goal is to be an even better steward for Java by reaching more of the Java ecosystem with face-to-face and online community engagements. We look forward to planning tours and events with you, members of the Java community.

  • Moving all UI logic to Client Side?

    - by Mag20
    Our team originally consisted of mostly server side developers with minimum expertise in Javascript. In ASP.NET we used to write a lot of UI logic in code-behind or more recently through controllers in MVC. A little while ago 2 high level client side developers joined our team. They can do in HTMl/CSS/Javascript pretty much anything that we could previously do with server-side code and server-side web controls: Show/hide controls Do validation Control AJAX refreshing So I started to think that maybe it would be more efficient to just create a high level API around our business logic, kinda like Amazon Fulfillment API: http://docs.amazonwebservices.com/fws/latest/APIReference/, so that client side developers would fully take over the UI, while server side developers would only concentrate on business logic. So for ordering system you would have a high level API like: OrderService.asmx CreateOrderResponse CreateOrder(CreateOrderRequest) AddOrderItem AddPayment - SubmitPayment - GetOrderByID FindOrdersByCriteria ... There would be JSON/REST access to API, so it would be easy to consume from client-side UI. We could use this API for both internal UI development and also for 3-rd parties to create their own applications. With advances in Javascript and availability of good client side developers, is it a good time to get rid of code-behind/controllers and just concentrate on developing high level APIs (ala Amazon) that client side developers can consume?

  • Microsoft and jQuery

    - by Rick Strahl
    The jQuery JavaScript library has been steadily getting more popular and with recent developments from Microsoft, jQuery is also getting ever more exposure on the ASP.NET platform including now directly from Microsoft. jQuery is a light weight, open source DOM manipulation library for JavaScript that has changed how many developers think about JavaScript. You can download it and find more information on jQuery on www.jquery.com. For me jQuery has had a huge impact on how I develop Web applications and was probably the main reason I went from dreading to do JavaScript development to actually looking forward to implementing client side JavaScript functionality. It has also had a profound impact on my JavaScript skill level for me by seeing how the library accomplishes things (and often reviewing the terse but excellent source code). jQuery made an uncomfortable development platform (JavaScript + DOM) a joy to work on. Although jQuery is by no means the only JavaScript library out there, its ease of use, small size, huge community of plug-ins and pure usefulness has made it easily the most popular JavaScript library available today. As a long time jQuery user, I’ve been excited to see the developments from Microsoft that are bringing jQuery to more ASP.NET developers and providing more integration with jQuery for ASP.NET’s core features rather than relying on the ASP.NET AJAX library. Microsoft and jQuery – making Friends jQuery is an open source project but in the last couple of years Microsoft has really thrown its weight behind supporting this open source library as a supported component on the Microsoft platform. When I say supported I literally mean supported: Microsoft now offers actual tech support for jQuery as part of their Product Support Services (PSS) as jQuery integration has become part of several of the ASP.NET toolkits and ships in several of the default Web project templates in Visual Studio 2010. The ASP.NET MVC 3 framework (still in Beta) also uses jQuery for a variety of client side support features including client side validation and we can look forward toward more integration of client side functionality via jQuery in both MVC and WebForms in the future. In other words jQuery is becoming an optional but included component of the ASP.NET platform. PSS support means that support staff will answer jQuery related support questions as part of any support incidents related to ASP.NET which provides some piece of mind to some corporate development shops that require end to end support from Microsoft. In addition to including jQuery and supporting it, Microsoft has also been getting involved in providing development resources for extending jQuery’s functionality via plug-ins. Microsoft’s last version of the Microsoft Ajax Library – which is the successor to the native ASP.NET AJAX Library – included some really cool functionality for client templates, databinding and localization. As it turns out Microsoft has rebuilt most of that functionality using jQuery as the base API and provided jQuery plug-ins of these components. Very recently these three plug-ins were submitted and have been approved for inclusion in the official jQuery plug-in repository and been taken over by the jQuery team for further improvements and maintenance. Even more surprising: The jQuery-templates component has actually been approved for inclusion in the next major update of the jQuery core in jQuery V1.5, which means it will become a native feature that doesn’t require additional script files to be loaded. Imagine this – an open source contribution from Microsoft that has been accepted into a major open source project for a core feature improvement. Microsoft has come a long way indeed! What the Microsoft Involvement with jQuery means to you For Microsoft jQuery support is a strategic decision that affects their direction in client side development, but nothing stopped you from using jQuery in your applications prior to Microsoft’s official backing and in fact a large chunk of developers did so readily prior to Microsoft’s announcement. Official support from Microsoft brings a few benefits to developers however. jQuery support in Visual Studio 2010 means built-in support for jQuery IntelliSense, automatically added jQuery scripts in many projects types and a common base for client side functionality that actually uses what most developers are already using. If you have already been using jQuery and were worried about straying from the Microsoft line and their internal Microsoft Ajax Library – worry no more. With official support and the change in direction towards jQuery Microsoft is now following along what most in the ASP.NET community had already been doing by using jQuery, which is likely the reason for Microsoft’s shift in direction in the first place. ASP.NET AJAX and the Microsoft AJAX Library weren’t bad technology – there was tons of useful functionality buried in these libraries. However, these libraries never got off the ground, mainly because early incarnations were squarely aimed at control/component developers rather than application developers. For all the functionality that these controls provided for control developers they lacked in useful and easily usable application developer functionality that was easily accessible in day to day client side development. The result was that even though Microsoft shipped support for these tools in the box (in .NET 3.5 and 4.0), other than for the internal support in ASP.NET for things like the UpdatePanel and the ASP.NET AJAX Control Toolkit as well as some third party vendors, the Microsoft client libraries were largely ignored by the developer community opening the door for other client side solutions. Microsoft seems to be acknowledging developer choice in this case: Many more developers were going down the jQuery path rather than using the Microsoft built libraries and there seems to be little sense in continuing development of a technology that largely goes unused by the majority of developers. Kudos for Microsoft for recognizing this and gracefully changing directions. Note that even though there will be no further development in the Microsoft client libraries they will continue to be supported so if you’re using them in your applications there’s no reason to start running for the exit in a panic and start re-writing everything with jQuery. Although that might be a reasonable choice in some cases, jQuery and the Microsoft libraries work well side by side so that you can leave existing solutions untouched even as you enhance them with jQuery. The Microsoft jQuery Plug-ins – Solid Core Features One of the most interesting developments in Microsoft’s embracing of jQuery is that Microsoft has started contributing to jQuery via standard mechanism set for jQuery developers: By submitting plug-ins. Microsoft took some of the nicest new features of the unpublished Microsoft Ajax Client Library and re-wrote these components for jQuery and then submitted them as plug-ins to the jQuery plug-in repository. Accepted plug-ins get taken over by the jQuery team and that’s exactly what happened with the three plug-ins submitted by Microsoft with the templating plug-in even getting slated to be published as part of the jQuery core in the next major release (1.5). The following plug-ins are provided by Microsoft: jQuery Templates – a client side template rendering engine jQuery Data Link – a client side databinder that can synchronize changes without code jQuery Globalization – provides formatting and conversion features for dates and numbers The first two are ports of functionality that was slated for the Microsoft Ajax Library while functionality for the globalization library provides functionality that was already found in the original ASP.NET AJAX library. To me all three plug-ins address a pressing need in client side applications and provide functionality I’ve previously used in other incarnations, but with more complete implementations. Let’s take a close look at these plug-ins. jQuery Templates http://api.jquery.com/category/plugins/templates/ Client side templating is a key component for building rich JavaScript applications in the browser. Templating on the client lets you avoid from manually creating markup by creating DOM nodes and injecting them individually into the document via code. Rather you can create markup templates – similar to the way you create classic ASP server markup – and merge data into these templates to render HTML which you can then inject into the document or replace existing content with. Output from templates are rendered as a jQuery matched set and can then be easily inserted into the document as needed. Templating is key to minimize client side code and reduce repeated code for rendering logic. Instead a single template can be used in many places for updating and adding content to existing pages. Further if you build pure AJAX interfaces that rely entirely on client rendering of the initial page content, templates allow you to a use a single markup template to handle all rendering of each specific HTML section/element. I’ve used a number of different client rendering template engines with jQuery in the past including jTemplates (a PHP style templating engine) and a modified version of John Resig’s MicroTemplating engine which I built into my own set of libraries because it’s such a commonly used feature in my client side applications. jQuery templates adds a much richer templating model that allows for sub-templates and access to the data items. Like John Resig’s original Micro Template engine, the core basics of the templating engine create JavaScript code which means that templates can include JavaScript code. To give you a basic idea of how templates work imagine I have an application that downloads a set of stock quotes based on a symbol list then displays them in the document. To do this you can create an ‘item’ template that describes how each of the quotes is renderd as a template inside of the document: <script id="stockTemplate" type="text/x-jquery-tmpl"> <div id="divStockQuote" class="errordisplay" style="width: 500px;"> <div class="label">Company:</div><div><b>${Company}(${Symbol})</b></div> <div class="label">Last Price:</div><div>${LastPrice}</div> <div class="label">Net Change:</div><div> {{if NetChange > 0}} <b style="color:green" >${NetChange}</b> {{else}} <b style="color:red" >${NetChange}</b> {{/if}} </div> <div class="label">Last Update:</div><div>${LastQuoteTimeString}</div> </div> </script> The ‘template’ is little more than HTML with some markup expressions inside of it that define the template language. Notice the embedded ${} expressions which reference data from the quote objects returned from an AJAX call on the server. You can embed any JavaScript or value expression in these template expressions. There are also a number of structural commands like {{if}} and {{each}} that provide for rudimentary logic inside of your templates as well as commands ({{tmpl}} and {{wrap}}) for nesting templates. You can find more about the full set of markup expressions available in the documentation. To load up this data you can use code like the following: <script type="text/javascript"> //var Proxy = new ServiceProxy("../PageMethods/PageMethodsService.asmx/"); $(document).ready(function () { $("#btnGetQuotes").click(GetQuotes); }); function GetQuotes() { var symbols = $("#txtSymbols").val().split(","); $.ajax({ url: "../PageMethods/PageMethodsService.asmx/GetStockQuotes", data: JSON.stringify({ symbols: symbols }), // parameter map type: "POST", // data has to be POSTed contentType: "application/json", timeout: 10000, dataType: "json", success: function (result) { var quotes = result.d; var jEl = $("#stockTemplate").tmpl(quotes); $("#quoteDisplay").empty().append(jEl); }, error: function (xhr, status) { alert(status + "\r\n" + xhr.responseText); } }); }; </script> In this case an ASMX AJAX service is called to retrieve the stock quotes. The service returns an array of quote objects. The result is returned as an object with the .d property (in Microsoft service style) that returns the actual array of quotes. The template is applied with: var jEl = $("#stockTemplate").tmpl(quotes); which selects the template script tag and uses the .tmpl() function to apply the data to it. The result is a jQuery matched set of elements that can then be appended to the quote display element in the page. The template is merged against an array in this example. When the result is an array the template is automatically applied to each each array item. If you pass a single data item – like say a stock quote – the template works exactly the same way but is applied only once. Templates also have access to a $data item which provides the current data item and information about the tempalte that is currently executing. This makes it possible to keep context within the context of the template itself and also to pass context from a parent template to a child template which is very powerful. Templates can be evaluated by using the template selector and calling the .tmpl() function on the jQuery matched set as shown above or you can use the static $.tmpl() function to provide a template as a string. This allows you to dynamically create templates in code or – more likely – to load templates from the server via AJAX calls. In short there are options The above shows off some of the basics, but there’s much for functionality available in the template engine. Check the documentation link for more information and links to additional examples. The plug-in download also comes with a number of examples that demonstrate functionality. jQuery templates will become a native component in jQuery Core 1.5, so it’s definitely worthwhile checking out the engine today and get familiar with this interface. As much as I’m stoked about templating becoming part of the jQuery core because it’s such an integral part of many applications, there are also a couple shortcomings in the current incarnation: Lack of Error Handling Currently if you embed an expression that is invalid it’s simply not rendered. There’s no error rendered into the template nor do the various  template functions throw errors which leaves finding of bugs as a runtime exercise. I would like some mechanism – optional if possible – to be able to get error info of what is failing in a template when it’s rendered. No String Output Templates are always rendered into a jQuery matched set and there’s no way that I can see to directly render to a string. String output can be useful for debugging as well as opening up templating for creating non-HTML string output. Limited JavaScript Access Unlike John Resig’s original MicroTemplating Engine which was entirely based on JavaScript code generation these templates are limited to a few structured commands that can ‘execute’. There’s no code execution inside of script code which means you’re limited to calling expressions available in global objects or the data item passed in. This may or may not be a big deal depending on the complexity of your template logic. Error handling has been discussed quite a bit and it’s likely there will be some solution to that particualar issue by the time jQuery templates ship. The others are relatively minor issues but something to think about anyway. jQuery Data Link http://api.jquery.com/category/plugins/data-link/ jQuery Data Link provides the ability to do two-way data binding between input controls and an underlying object’s properties. The typical scenario is linking a textbox to a property of an object and have the object updated when the text in the textbox is changed and have the textbox change when the value in the object or the entire object changes. The plug-in also supports converter functions that can be applied to provide the conversion logic from string to some other value typically necessary for mapping things like textbox string input to say a number property and potentially applying additional formatting and calculations. In theory this sounds great, however in reality this plug-in has some serious usability issues. Using the plug-in you can do things like the following to bind data: person = { firstName: "rick", lastName: "strahl"}; $(document).ready( function() { // provide for two-way linking of inputs $("form").link(person); // bind to non-input elements explicitly $("#objFirst").link(person, { firstName: { name: "objFirst", convertBack: function (value, source, target) { $(target).text(value); } } }); $("#objLast").link(person, { lastName: { name: "objLast", convertBack: function (value, source, target) { $(target).text(value); } } }); }); This code hooks up two-way linking between a couple of textboxes on the page and the person object. The first line in the .ready() handler provides mapping of object to form field with the same field names as properties on the object. Note that .link() does NOT bind items into the textboxes when you call .link() – changes are mapped only when values change and you move out of the field. Strike one. The two following commands allow manual binding of values to specific DOM elements which is effectively a one-way bind. You specify the object and a then an explicit mapping where name is an ID in the document. The converter is required to explicitly assign the value to the element. Strike two. You can also detect changes to the underlying object and cause updates to the input elements bound. Unfortunately the syntax to do this is not very natural as you have to rely on the jQuery data object. To update an object’s properties and get change notification looks like this: function updateFirstName() { $(person).data("firstName", person.firstName + " (code updated)"); } This works fine in causing any linked fields to be updated. In the bindings above both the firstName input field and objFirst DOM element gets updated. But the syntax requires you to use a jQuery .data() call for each property change to ensure that the changes are tracked properly. Really? Sure you’re binding through multiple layers of abstraction now but how is that better than just manually assigning values? The code savings (if any) are going to be minimal. As much as I would like to have a WPF/Silverlight/Observable-like binding mechanism in client script, this plug-in doesn’t help much towards that goal in its current incarnation. While you can bind values, the ‘binder’ is too limited to be really useful. If initial values can’t be assigned from the mappings you’re going to end up duplicating work loading the data using some other mechanism. There’s no easy way to re-bind data with a different object altogether since updates trigger only through the .data members. Finally, any non-input elements have to be bound via code that’s fairly verbose and frankly may be more voluminous than what you might write by hand for manual binding and unbinding. Two way binding can be very useful but it has to be easy and most importantly natural. If it’s more work to hook up a binding than writing a couple of lines to do binding/unbinding this sort of thing helps very little in most scenarios. In talking to some of the developers the feature set for Data Link is not complete and they are still soliciting input for features and functionality. If you have ideas on how you want this feature to be more useful get involved and post your recommendations. As it stands, it looks to me like this component needs a lot of love to become useful. For this component to really provide value, bindings need to be able to be refreshed easily and work at the object level, not just the property level. It seems to me we would be much better served by a model binder object that can perform these binding/unbinding tasks in bulk rather than a tool where each link has to be mapped first. I also find the choice of creating a jQuery plug-in questionable – it seems a standalone object – albeit one that relies on the jQuery library – would provide a more intuitive interface than the current forcing of options onto a plug-in style interface. Out of the three Microsoft created components this is by far the least useful and least polished implementation at this point. jQuery Globalization http://github.com/jquery/jquery-global Globalization in JavaScript applications often gets short shrift and part of the reason for this is that natively in JavaScript there’s little support for formatting and parsing of numbers and dates. There are a number of JavaScript libraries out there that provide some support for globalization, but most are limited to a particular portion of globalization. As .NET developers we’re fairly spoiled by the richness of APIs provided in the framework and when dealing with client development one really notices the lack of these features. While you may not necessarily need to localize your application the globalization plug-in also helps with some basic tasks for non-localized applications: Dealing with formatting and parsing of dates and time values. Dates in particular are problematic in JavaScript as there are no formatters whatsoever except the .toString() method which outputs a verbose and next to useless long string. With the globalization plug-in you get a good chunk of the formatting and parsing functionality that the .NET framework provides on the server. You can write code like the following for example to format numbers and dates: var date = new Date(); var output = $.format(date, "MMM. dd, yy") + "\r\n" + $.format(date, "d") + "\r\n" + // 10/25/2010 $.format(1222.32213, "N2") + "\r\n" + $.format(1222.33, "c") + "\r\n"; alert(output); This becomes even more useful if you combine it with templates which can also include any JavaScript expressions. Assuming the globalization plug-in is loaded you can create template expressions that use the $.format function. Here’s the template I used earlier for the stock quote again with a couple of formats applied: <script id="stockTemplate" type="text/x-jquery-tmpl"> <div id="divStockQuote" class="errordisplay" style="width: 500px;"> <div class="label">Company:</div><div><b>${Company}(${Symbol})</b></div> <div class="label">Last Price:</div> <div>${$.format(LastPrice,"N2")}</div> <div class="label">Net Change:</div><div> {{if NetChange > 0}} <b style="color:green" >${NetChange}</b> {{else}} <b style="color:red" >${NetChange}</b> {{/if}} </div> <div class="label">Last Update:</div> <div>${$.format(LastQuoteTime,"MMM dd, yyyy")}</div> </div> </script> There are also parsing methods that can parse dates and numbers from strings into numbers easily: alert($.parseDate("25.10.2010")); alert($.parseInt("12.222")); // de-DE uses . for thousands separators As you can see culture specific options are taken into account when parsing. The globalization plugin provides rich support for a variety of locales: Get a list of all available cultures Query cultures for culture items (like currency symbol, separators etc.) Localized string names for all calendar related items (days of week, months) Generated off of .NET’s supported locales In short you get much of the same functionality that you already might be using in .NET on the server side. The plugin includes a huge number of locales and an Globalization.all.min.js file that contains the text defaults for each of these locales as well as small locale specific script files that define each of the locale specific settings. It’s highly recommended that you NOT use the huge globalization file that includes all locales, but rather add script references to only those languages you explicitly care about. Overall this plug-in is a welcome helper. Even if you use it with a single locale (like en-US) and do no other localization, you’ll gain solid support for number and date formatting which is a vital feature of many applications. Changes for Microsoft It’s good to see Microsoft coming out of its shell and away from the ‘not-built-here’ mentality that has been so pervasive in the past. It’s especially good to see it applied to jQuery – a technology that has stood in drastic contrast to Microsoft’s own internal efforts in terms of design, usage model and… popularity. It’s great to see that Microsoft is paying attention to what customers prefer to use and supporting the customer sentiment – even if it meant drastically changing course of policy and moving into a more open and sharing environment in the process. The additional jQuery support that has been introduced in the last two years certainly has made lives easier for many developers on the ASP.NET platform. It’s also nice to see Microsoft submitting proposals through the standard jQuery process of plug-ins and getting accepted for various very useful projects. Certainly the jQuery Templates plug-in is going to be very useful to many especially since it will be baked into the jQuery core in jQuery 1.5. I hope we see more of this type of involvement from Microsoft in the future. Kudos!© Rick Strahl, West Wind Technologies, 2005-2010Posted in jQuery  ASP.NET

  • Open Data, Government and Transparency

    - by Tori Wieldt
    A new track at TDC (The Developer's Conference in Sao Paulo, Brazil) is titled Open Data. It deals with open data, government and transparency. Saturday will be a "transparency hacker day" where developers are invited to create applications using open data from the Brazilian government.  Alexandre Gomes, co-lead of the track, says "I want to inspire developers to become "Civic hackers:" developers who create apps to make society better." It is a chance for developers to do well and do good. There are many opportunities for developers, including monitoring government expenditures and getting citizens involved via social networks. The open data movement is growing worldwide. One initiative, the Open Government Partnership, is working to make government data easier to find and access. Making this data easily available means that with the right applications, it will be easier for people to make decisions and suggestions about government policies based on detailed information. Last April, the Open Government Partnership held its annual meeting in Brasilia, the capitol of Brazil. It was a great success showcasing the innovative work being done in open data by governments, civil societies and individuals around the world. For example, Bulgaria now publishes daily data on budget spending for all public institutions. Alexandre Gomes Explains Open Data At TDC, the Open Data track will include a presentation of examples of successful open data projects, an introduction to the semantic web, how to handle big data sets, techniques of data visualization, and how to design APIs.The other track lead is Christian Moryah Miranda, a systems analyst for the Brazilian Government's Ministry of Planning. "The Brazilian government wholeheartedly supports this effort. In order to make our data available to the public, it forces us to be more consistent with our data across ministries, and that's a good step forward for us," he said. He explained the government knows they cannot achieve everything they would like without help from the public. "It is not the government versus the people, rather citizens are partners with the government, and together we can achieve great things!" Miranda exclaimed. Saturday at TDC will be a "transparency hacker day" where developers will be invited to create applications using open data from the Brazilian government. Attendees are invited to pitch their ideas, work in small groups, and present their project at the end of the conference. "For example," Gomes said, "the Brazilian government just released the salaries of all government employees and I can't wait to see what developers can do with that."

  • JavaOne in Brazil

    - by janice.heiss(at)oracle.com
    JavaOne in Brazil, currently taking place in Sao Paolo, is one event I'd love to attend. I once heard "father of Java" James Gosling talk about Java developers throughout the world. He observed that there were good developers everywhere. It was not the case, he said, that that the really good developers are in one place and the not-so-good developers are in another. He encountered excellent developers everywhere. Then he paused and said that the craziest developers were definitely the Brazilians. As anyone who knows James would realize, this was meant as high praise. He said the Brazilians would work through the night on projects and were very enthusiastic and spontaneous - features that Brazilian culture is known for. Brazilian developers are responsible for creating one of the most impressive uses of Java ever - the applications that run the Brazilian health services. Starting from scratch they created a system that enables an expert doctor in Rio to look at an X-Ray of a patient near the Amazon and offer advice. One of the main architects of this was Java Champion Fabinane Nardon the distinguished Brazilian Java architect and open-source evangelist. As she writes in her blog:"In 2003, I was invited to assemble a team and architect a Public Healthcare Information System for the city of São Paulo, the largest in Latin America, with 14 million inhabitants. The resulting software had 2.5 million of lines of code and it was created, from specification to production, in only 10 months. At the time, the software was considered the largest J2EE application in the world and was featured in several articles, as this one. As a result, we won the Duke's Choice Award in 2005 during JavaOne, the largest development conference in the world. At the time, Sun Microsystems make a short documentary about our work." "In 2007, a lightning struck twice and I was again invited to assemble a new team and architect an even larger information system for healthcare. And thus I became CTO and one of the founders of Zilics Healthcare Information Systems. "In 2010, I started to research and work on Cloud Computing technology and became leader of the LSI-TEC Cloud Computing group. LSI-TEC is a research laboratory in the University of Sao Paulo, one of the best in Brazil. Thus, I became one of the ghost writers behind the popular Cloud Computing Twitter @the_cloud."You can see and hear Nardon in a 4 minute documentary on Java and the Brazilian health care system produced by Sun Microsystems. And you can listen to a September 2010 podcast with Nardon and her fellow Brazilian Java Champion Bruno Souza (known in Brazil as "Java Man") here at 11:10 minutes into the podcast.Next year, I'll hope to be reporting in Brazil at JavaOne!
