• Throwing Exception in CTOR and Smart Pointers

  - by David Relihan

  Is it OK to have the following code in my constructor to load an XML document into a member variable - throwing to caller if there are any problems: MSXML2::IXMLDOMDocumentPtr m_docPtr; //member Configuration() { try { HRESULT hr = m_docPtr.CreateInstance(__uuidof(MSXML2::DOMDocument40)); if ( SUCCEEDED(hr)) { m_docPtr->loadXML(CreateXML()); } else { //throw exception to caller } } catch(...) { //throw exception to caller } } Based on Scott Myers RAII implementations in More Effective C++ I believe I am alright in just allowing exceptions to be thrown from CTOR as I am using a smart pointer(IXMLDOMDocumentPtr). Let me know what you think....

• In MVC2, how do I validate fields that aren't in my data model?

  - by Andy Evans

  I am playing with MVC2 in VS 2010 and am really getting to like it. In a sandbox application that I've started from scratch, my database is represented in an ADO.NET entity data model and have done much of the validation for fields in my data model using Scott Guthrie's "buddy class" approach which has worked very well. However, in a user registration form that I have designed and am experimenting with, I'd like to add a 'confirm email address' or a 'confirm password' field. Since these fields obviously wouldn't exist in my data model, how would I validate these fields client side and server side? I would like to implement something like 'Html.ValidationMessageFor', but these fields don't exist in the data model. Any help would be greatly appreciated.

• Generic Method to find the tuples used for computation in Postgres?

  - by Rahul

  If I have a table col1 | name | pay ------+------------------+------ 1 | Steve Jobs | 1006 2 | Mike Markkula | 1007 3 | Mike Scott | 1978 4 | John Sculley | 1983 5 | Michael Spindler | 1653 The user executes a sum query which sums the pay of people getting paid more than $1500. Is there a way to also implicitly know which tuples have been used which satisfy the condition for sum ? I know you can separately write another query to just return the primary key ids which satisfy the condition. But, Is there any other way to do that in the same query ? probably rewrite the query in some way ? or... any suggestion ?

• Generate SQL Server Express database from Entity Framework 4 model

  - by Cranialsurge

  I am able to auto-generate a SQL Server CE 4.0 *.sdf file using code-first generation as explained by Scott Guthrie here. The connection string for the same is as follows: <add name="NerdDinners" providerName="System.Data.SqlServerCe.4.0" connectionString="data source=|DataDirectory|NerdDinner.sdf"/> However if I try to generate an mdf instead using the following connection string, it fails to do so with the following error - "The provider did not return a ProviderManifestToken string.". <add name="NerdDinners" providerName="System.Data.SqlClient" connectionString="data source=|DataDirectory|NerdDinner.mdf"/> Even directly hooking into a SQLEXPRESS instance using the following connection string fails <add name="NerdDinners" providerName="System.Data.SqlClient" connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=NerdDinner;Integrated Security=True"/> Does EF 4 only support SQL CE 4.0 for database creation from a model for now or am I doing something wrong here?

• Website settings for running visual web as root?

  - by Curtis White

  Scott Gu explains how to run visual web developer using a root path, here: http://weblogs.asp.net/scottgu/archive/2006/12/19/tip-trick-how-to-run-a-root-site-with-the-local-web-server-using-vs-2005-sp1.aspx This worked exactly as he described in one instance for me. But, today I do not see this option. More over, I do not think I have a solution file, and I think that has something to do with it. I'm aware there are web application projects and web site model, and web site model is basically just a "directory". But can web site model, also, have a solution file for this setting or not a solution file? What determines that? I am interested in using this method on on a web site, i.e directory only model.

• ASP.NET 4.0 webforms routing

  - by Ethan

  I have an existing site that I'd like to convert to use routing, and after reading Scott Guthrie's post here, I built a working sample that works for most circumstances. However, since not all of the pages on the existing site match a particular pattern, I'll need to check against a database to determine which route (destination .aspx page) to use. For example, most pages are like this: http://www.mysite.com/people/person.html This is fine - I can easily route these to the view_person.aspx page because of the 'people' directory. But some pages are like this: http://www.mysite.com/category_page.html http://www.mysite.com/product_page.html This necessitates checking the database to see whether to route to the view_category.aspx page or the view_product.aspx page. And this is where I'm stuck. Do I create an IRouteHandler that checks the database and returns the route? Or is there a better way? The only code I've found that kind of fits is the answer to this question. Thanks in advance.

• Learn Fundamentals of Silverlight 4 Data Binding

  - by Eric J.

  I'm just starting to work with Silverlight (no WPF experience either) and am having a difficult time finding a source that provides a full explanation of Data Binding. There is absolutely no lack of tutorials (starting with the ones on Silverlight.net or Scott Gu's blogs), but everything I have found is "by example". Is there a resource that explains how data binding works in Silverlight, from a Fundamental/Conceptual perspective, and provides end-to-end coverage of data binding features? The desire for a more fundamental source of information is driven by a number of questions that came up this afternoon in reviewing tutorials and writing sample apps, such as: Why can't I bind the value of a slider like this?: Value="{Binding=Age, Mode=TwoWay}" where Age refers to an int property in the object data context I bind in code-behind (the Visual Studio error message is Expected '[]'. How do I use the DataContext property in VS 2010? What's a Path, Relative Source, Static Source, ...?

• Add version control to existing SQL Server database

  - by ederbf

  I am part of a development team currently working with a database that does not have any kind of source control. We work with SQL Server 2008 R2 and have always managed the DB directly with SSMS. It now has ~340 tables and ~1600 stored procedures, plus a few triggers and views, so it is not a small DB. My goal is to have the DB under version control, so I have been reading articles, like Scott Allen's series (http://bitly.com/9cJmGR) and many old SO related questions. But I am still unable to decide on how to proceed. What I'm thinking of is to script the database schema in one file, then procedures, triggers and views in one file each. Then keep everything versioned under Mercurial. But of course, every member of the team can access SSMS and directly change the schema and procedures, with the possibility that any of us can forget to replicate those changes in the versioned files. What better options are there? And, did I forget any element worth having source control of?

• When to use MVC Scaffolding via NuGet vs MVC Scaffolding via MVC3 Tools Update

  - by James

  I am a little confused about the various different "mainstream" scaffolding options for MVC3. There is a NuGet package called MVCScaffolding. It first showed up in Jan 2011, but seems to be active and have recent updates, and be developed by Scott Hanselman, among others. Then in May 2011 came the MVC3 Tools Update. This seems like it incorporated the original scaffolding ideas into an "out of the box" scaffolding options. However, this has not been updated since. So - what is the relationship between these two scaffoldings (if any). Are there cases when one should be used over the other, or is it just a matter of taste? Does Visual Studio 2012 or MVC4 change the game on any of this? Thanks for any input.

• PL DOC source forge - 2 issues

  - by user1792793

  I'm attempting to use PLDOC source forge (http://pldoc.sourceforge.net/maven-site/) with my code to generate a neat page with comments of my liking. I'm coming across 2 issues, any help would be appreciated. 1 I've been using tags (/**, */) to make comments and this works perfectly for functions, but does not appear in procedures. My Functions and procedures are independent and not in packages, and trying to add comments before the PROCEDURE declaration just gets deleted when saved. 2 if i try to use the recommended method of getting the data directly from teh database (call pldoc.bat -url jdbc:oracle:thin:@localhost:1521:ORCL -user SCOTT -password TIGER -sql SYS_OWNER.DBMS_PIPE,SYS_OWNER.DBMS_OUTPUT), it puts all the available functions and procedures under the user SIS_OWNER (SIS_owner is the only link available on the left hand side). I want to change this so that I can view all the methods in the list instead. Problem with procedures stated in 1 still exists with this method. Please let me know if you have overcome this and any pointers would be great. Thanks

• aspnet_regsql questions and users and role

  - by Alexander

  I spend quite some hours banging my head against the wall trying to set up the aspnet membership / roles tables in my SQL server database instead of having them exist inside the App_Code/ASPNETDB.MDF file because that file wasn't working correctly on my host. I eventually figured out the problem by following Scott's gu here and was able to resolve it by running the aspnet_regsql.exe utility and creating a connection string for LocalSqlServer. The ridiculous part about it is that after running the aspnet_regsql and upload my database to my webhost all of my users and role that I have already created is gone. The user, membership, role, etc is gone. I can't populate this using the Web Site Administration Tool as it's not visual studio now. So what is the easiest way to populate the user, role, etc to my SQL Server as I now have dbo.aspnet_Application, dbo.aspnet_Paths, dbo.aspnet_Roles, etc...etc...

• iPhone CoreData Migration and modifying data

  - by ScottL

  I have an app that has both static data and user entered data in the CoreData store. I understand how to do a lightweight migration to a new database version, but how to I add or modify the static data without affecting the users data? If I have 50 static data entries to add and a couple to modify (ie. spelling mistakes) should they be stored in a different sqlite db and copied over? Also, is it possible to look at the version of the data store so that this copy only happens the first time the app is started up after upgrading? Sorry for the general noob type question, but this is the first time I have ever had to deal with this sort of issue. Thanks, Scott

• Building Visual Studio Setup Projects with TFS 2010 Team Build

  - by Jakob Ehn

  One of the most common complaints from people starting to use Team Build is that is doesn’t support building Microsoft’s own Setup and Deployment project (*.vdproj). When creating a default build definition that compiles a solution containing a setup project, you’ll get the following warning: The project file "MyProject.vdproj" is not supported by MSBuild and cannot be built.   This is what the problem is all about. MSBuild, that is used for compiling your projects, does not understand the proprietary vdproj format defined by Microsoft quite some time ago. Unfortunately there is no sign that this will change in the near future, in fact the setup projects has barely changed at all since they were introduced. VS 2010 brings no new features or improvements hen it comes to the setup projects. VS 2010 does include a limited version of InstallShield which promises to be more MSBuild friendly and with more or less the same features as VS setup projects. I hope to get a closer look at this installer project type soon. But, how do we go about to build a Visual Studio setup project and produce an MSI as part of a Team Build process? Well, since only one application known to man understands the vdproj projects, we will have to installa copy of Visual Studio on the build server. Sad but true. After doing this, we use the Visual Studio command line interface (devenv) to perform the build. In this post I will show how to do this by using the InvokeProcess activity directly in a build workflow template. You’ll want to run build your setup projects after you have successfully compiled the projects.   Install Visual Studio 2010 on the build server(s)   Open your build process template /remember to branch or copy the xaml file before modifying it!)   Locate the Try to Compile the Project activity   Drop an instance of the InvokeProcess activity from the toolbox onto the designer, after the Run MSBuild for Project activity   Drop an instance of the WriteBuildMessage activity inside the Handle Standard Output section. Set the Importance property to Microsoft.TeamFoundation.Build.Client.BuildMessageImportance.High (NB: This is necessary if you want the output from devenv to show up in the build log when running the build with the default verbosity) Set the Message property to stdOutput   Drop an instance of the WriteBuildError activity to the Handle Error Output section Set the Message property to errOutput   Select the InvokeProcess activity and set the values of the parameters to:     The finished workflow should look like this:     This will generate the MSI files, but they won’t be copied to the drop location. This is because we are using devenv and not MSBuild, so we have to do this explicitly   Drop a Sequence activity somewhere after the Copy to Drop location activity.   Create a variable in the Sequence activity of type IEnumerable<String> and call it GeneratedInstallers   Drop a FindMatchingFiles activity in the sequence activity and set the properties to:     Drop a ForEach<String> activity after the FindMatchingFiles activity. Set the Value property to GeneratedInstallers   Drop an InvokeProcess activity inside the ForEach activity.  FileName: “xcopy.exe” Arguments: String.Format("""{0}"" ""{1}""", item, BuildDetail.DropLocation) The Sequence activity should look like this:     Save the build process template and check it in.   Run the build and verify that the MSI’s is built and copied to the drop location.   Note 1: One of the drawback of using devenv like this in a team build is that since all the output from the default compilations is placed in the Binaries folder, the outputs is not avaialable when devenv is invoked, which causes the whole solution to rebuild again. In TFS 2008, this was pretty simple to fix by using the CustomizableOutDir property. In TFS 2010, the same feature is not avaialble. Jim Lamb blogged about this recently, have a look at it if you have a problem with this: http://blogs.msdn.com/jimlamb/archive/2010/04/13/customizableoutdir-in-tfs-2010.aspx   Note 2: Although the above solution works, a better approach is to wrap this in a custom activity that you can use in your builds. I will come back to this in a future post.

• 5 Steps to getting started with IronRuby

  - by Eric Nelson

  IronRuby is a Open Source implementation of the Ruby programming language for .NET, heavily relying on Microsoft's Dynamic Language Runtime. The project's #1 goal is to be a true Ruby implementation, meaning it runs existing Ruby code. Check out this summary of using the Ruby standard library and 3rd party libraries in IronRuby. IronRuby has tight integration with .NET, so any .NET types can be used from IronRuby and the IronRuby runtime can be embedded into any .NET application. These 5 steps should get you nicely up and running on IronRuby – OR … you could just watch a video session from the lead developer which took place earlier this month (March 2010 - 60mins). But the 5 steps will be quicker :-) Step 1 – Install IronRuby :-) You can install IronRuby automatically using an MSI or manually. For simplicity I would recommend the MSI install. TIP: As of the 25th of March IronRuby has not quite shipped. The download above is a Release Candidate (RC) which means it is still undergoing final testing by the team. You will need to uninstall this version (RC3) once the final release is available. The good news is that uninstalling IronRuby RC3 will work without a hitch as the MSI does relatively little. Step 2 – Install an IronRuby friendly editor You will need to Install an editor to work with IronRuby as there is no designer support for IronRuby inside Visual Studio. There are many editors to choose from but I would recommend you either went with: SciTE (Download the MSI): This is a lightweight text editor which is simple to get up and running. SciTE understands Ruby syntax and allows you to easily run IronRuby code within the editor with a small change to the config file. SharpDevelop 3.2 (Download the MSI): This is an open source development environment for C#, VB, Boo and now IronRuby. IronRuby support is new but it does include integrated debugging. You might also want to check out the main site for SharpDevelop. TIP: There are commercial tools for Ruby development which offer richer support such as intellisense.. They can be coerced into working with IronRuby. A good one to start with is RubyMine which needs some small changes to make it work with IronRuby. Step 3 – Run the IronRuby Tutorial Run through the IronRuby tutorial which is included in the IronRuby download. It covers off the basics of the Ruby languages and how IronRuby integrates with .NET. In a typical install it will end up at C:\Program Files\IronRuby 0.9.4.0\Samples\Tutorial. Which will give you the tutorial implemented in .NET and Ruby. TIP: You might also want to check out these two introductory posts Using IronRuby and .NET to produce the ‘Hello World of WPF’ and What's IronRuby, and how do I put it on Rails? Step 4 – Get some good books to read Get a great book on Ruby and IronRuby. There are several free ebooks on Ruby which will help you learn the language. The little book of Ruby is a good place to start. I would also recommend you purchase IronRuby Unleashed (Buy on Amazon UK | Buy on Amazon USA). You might also want to check out this mini-review. Other books are due out soon including IronRuby in Action. TIP: Also check out the official documentation for using .NET from IronRuby. Step 5 – Keep an eye on the team blogs Keep an eye on the IronRuby team blogs including Jimmy Schementi, Jim Deville and Tomas Matousek (full list) TIP: And keep a watch out for the final release of IronRuby – due anytime soon!

• They may block off Howard Street—but Oracle OpenWorld is a two-way street.

  - by Oracle Accelerate for Midsize Companies

  Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 by Jim Lein, Sr. Director, Oracle Accelerate for Midsize Companies “Engineered to Inform and Inspire”—that’s the theme of Oracle OpenWorld 2012. In early October, tens of thousands of attendees will descend on the streets of San Francisco because they share one thing in common: the desire to learn more about Oracle. You might think that’s the way we, Oracle employees, look at this event—as just another opportunity for attendees to learn about what we do. But it’s really a two way street. Every year I’m amazed by how informed and inspired I am by our customers and their companies. Midsize companies buy Oracle to grow. As part of the Oracle Accelerate for Midsize Companies team I get to talk with our partners and business leaders at growing companies almost every day, usually via phone. Oracle OpenWorld presents the perfect opportunity to meet some of them in person, in an informal setting, and in one of the most beautiful cities in the world. The stories our customers tell me about their businesses provide vivid examples of how they have overcome the challenges of managing increasingly complex global operations and growing during uncertain economic conditions. It’s no secret that my favorite session at Oracle OpenWorld (besides Larry Ellison’s keynotes and the Customer Appreciation Event, of course) is the Oracle Accelerate Customer Panel. This year we’re featuring executives from three companies who deployed Oracle ERP rapidly to support their company’s growth: Chris Powell, VP and Corporate Controller of Beats by Dr. Dre, a California based designer and manufacturer of premium headphones (sorry, no free samples), Iñaki Zuazo, CIO of Industrias Juno, a building materials provider based in Spain, Kamran Moosa, Project Coordinator for Spartan Engineering, a provider of engineering and construction support services for an LPG storage project in Texas, and That’s a pretty diverse lineup and it will be interesting to hear the perspectives of both IT and financial project stakeholders. The session, “Oracle Accelerate Customer Case Studies: Rapid Deployment of Oracle Applications”, is at 3:30 pm on Wednesday, October 3, in the Concert room at the Palace Hotel. Oracle loves our hometown of San Francisco and it’s a great place to host Oracle OpenWorld. It’s now San Francisco’s largest conference and the city closes off Howard Street to better accommodate the attendees. Some Bay Area commuters may be inconvenienced for a few days by this closure but the conference brings about $100 million into the local economy. Now that’s a two-way street.

• Adding Fake Build Information in TFS 2010

  - by Jakob Ehn

  We have been using TFS 2010 build for distributing a build in parallel on several agents, but where the actual compilation is done by a bunch of external tools and compilers, e.g. no MSBuild involved. We are using the ParallelTemplate.xaml template that Jim Lamb blogged about previously, which distributes each configuration to a different agent. We developed custom activities for running these external compilers and collecting the information and errors by reading standard out/error and pushing it back to the build log. But since we aren’t using MSBuild we don’t the get nice configuration summary section on the build summary page that we are used to. We would like to show the result of each configuration with any errors/warnings as usual, together with a link to the log file. TFS 2010 API to the rescue! What we need to do is adding information to the InformationNode structure that is associated with every TFS build. The log that you normally see in the Log view is built up as a tree structure of IBuildInformationNode objects. This structure can we accessed by using the InformationNodeConverters class. This class also contain some helper methods for creating BuildProjectNode, which contain the information about each project that was build, for example which configuration, number of errors and warnings and link to the log file. Here is a code snippet that first creates a “fake” build from scratch and the add two BuildProjectNodes, one for Debug|x86 and one for Release|x86 with some release information:   TfsTeamProjectCollection collection = TfsTeamProjectCollectionFactory.GetTeamProjectCollection(new Uri("http://lt-jakob2010:8080/tfs")); IBuildServer buildServer = collection.GetService<IBuildServer>(); var buildDef = buildServer.GetBuildDefinition("TeamProject", "BuildDefinition"); //Create fake build with random build number var detail = buildDef.CreateManualBuild(new Random().Next().ToString()); // Create Debug|x86 project summary IBuildProjectNode buildProjectNode = detail.Information.AddBuildProjectNode(DateTime.Now, "Debug", "MySolution.sln", "x86", "$/project/MySolution.sln", DateTime.Now, "Default"); buildProjectNode.CompilationErrors = 1; buildProjectNode.CompilationWarnings = 1; buildProjectNode.Node.Children.AddBuildError("Compilation", "File1.cs", 12, 5, "", "Syntax error", DateTime.Now); buildProjectNode.Node.Children.AddBuildWarning("File2.cs", 3, 1, "", "Some warning", DateTime.Now, "Compilation"); buildProjectNode.Node.Children.AddExternalLink("Log File", new Uri(@"\\server\share\logfiledebug.txt")); buildProjectNode.Save(); // Create Releaes|x86 project summary buildProjectNode = detail.Information.AddBuildProjectNode(DateTime.Now, "Release", "MySolution.sln", "x86", "$/project/MySolution.sln", DateTime.Now, "Default"); buildProjectNode.CompilationErrors = 0; buildProjectNode.CompilationWarnings = 0; buildProjectNode.Node.Children.AddExternalLink("Log File", new Uri(@"\\server\share\logfilerelease.txt")); buildProjectNode.Save(); detail.Information.Save(); detail.FinalizeStatus(BuildStatus.Failed); When running this code, it will a create a build that looks like this: As you can see, it created two configurations with error and warning information and a link to a log file. Just like a regular MSBuild would have done. This is very useful when using TFS 2010 Build in heterogeneous environments. It would also be possible to do this when running compilations completely outside TFS build, but then push the results of the into TFS for easy access. You can push all information, including the compilation summary, drop location, test results etc using the API.

• Gamify your Web

  - by Isabel F. Peñuelas

  Yesterday Valencia welcomed the Gamification World Congress that I follow virtually through #GWC2012. BBVA, Iberia, Ligeresa, Axe, Wayra, ESADE, GlaxoSmithKline, Macmillan, Gamisfaction, Nomaders, Blaffin were among the companies presenting success stories on gaming. It has been proved that people remember things easily when an emotion is created. The marketing expectations around Gamification techniques have a lot to do with Neuromarketing theories. There are a lot of expectations on internal enterprise Gamification. In the public Web some sectors are taking the lead on following the trend. The Gartner Analyst Brian Burke opened another Gamification recent event in Madrid remembering that “Gamification is mostly about Engagement”, and this can be applied both to customers or employees. Gamification and Banking The experience of the Spanish Financial Group BBVA that just launched BBVA Game was also presented a week ago at the BBVA Innovation Centre during the event “Gamification & Banking: a fad or a serious business?” . One of the objectives of the BBVA Game was to double the name of registered users. “People like the efficiency of the online channel want to keep a one-to-one contact with the brand”-explained Bernardo Crespo. Another interested data coming out the BBVA presentation was that “only 20% of Spanish users –out of the total holders of Bank Accounts in the country- is familiar with the use of a Web Site to consult their bank accounts”, the project aims also to reverse this situation helping people to learn making a heavy use of the Video in the gaming context. In general Banking presenters seem to agree that Gamification techniques are helping to increase the time spent on the Web. Gamification and Health Using Gamification techniques for chronic illness rehabilitation was another topic of the World Congress. Here you can find some ideas and experiences What can games do for the health (In Spanish) I have personally started my own mental-health gaming project at http://www.lumosity.com/ Gamification in the Enterprise I really recommend Reading this excellent post of Ultan ÓBroin my Introduction to Gamification and Applications. Employee´s motivation and learning are experiencing a 360º turn and it looks than some of us will become soon the Dragon of the year instead of the Employee of the Year. Using Web 2.0 Tools for Gamification Projects  What type of tools do we need for a quick-win Gamification project? To certain extend Gamification can be considered an evolution of the participative Web. Badging, avatars, points and awards, leader boards, progress charts, virtual currencies, gifting and giving challenges and quests are common components and elements. The Web is offering new development frameworks to that purpose as this Avatar Framework from Paypal or Badgeville to include in web applications. Besides, tools to create communities around a game are required to comment, share and vote players as well as for an efficient multimedia management. Due to its entirely open architecture, its community features, and its multimedia and imaging solutions is were I see WebCenter as a tool helping brands to success.

• How can I thoroughly evaluate a prospective employer?

  - by glenviewjeff

  We hear much about code smells, test smells, and even project smells, but I have heard no discussion about employer "smells" outside of the Joel Test. After much frustration working for employers with a bouquet of unpleasant corporate-culture odors, I believe it's time for me to actively seek a more mature development environment. I've started assembling a list of questions to help vet employers by identifying issues during a job interview, and am looking for additional ideas. I suppose this list could easily be modified by an employer to vet an employee as well, but please answer from the interviewee's perspective. I think it would be important to ask many of these questions of multiple people to find out if consistent answers are given. For the most part, I tried to put the questions in each section in the order they could be asked. An undesired answer to an early question will often make follow-ups moot. Values What constitutes "well-written" software? What attributes does a good developer have? Same question for manager. Process Do you have a development process? How rigorously do you follow it? How do you decide how much process to apply to each project? Describe a typical project lifecycle. Ask the following if they don't come up otherwise: Waterfall/iterative: How much time is spent in upfront requirements gathering? upfront design? Testing Who develops tests (developers or separate test engineers?) When are they developed? When are the tests executed? How long do they take to execute? What makes a good test? How do you know you've tested enough? What percentage of code is tested? Review What is the review process like? What percentage of code is reviewed? Design? How frequently can I expect to participate as code/design reviewer/reviewee? What are the criteria applied to review and where do the criteria come from? Improvement What new tools and techniques have you evaluated or deployed in the past year? What training courses have your employees been given in the past year? What will I be doing for the first six months in your company (hinting at what kind of organized mentorship/training has been thought through, if any) What changes to your development process have been made in the past year? How do you improve and learn from your mistakes as an organization? What was your organizations biggest mistake in the past year, and how was it addressed? What feedback have you given to management lately? Was it implemented? If not, why? How does your company use "best practices?" How do you seek them out from the outside or within, and how do you share them with each other? Ethics Tell me about an ethical problem you or your employees experienced recently and how was it resolved? Do you use open-source software? What open-source contributions have you made? Follow-Ups I liked what @jim-leonardo said on this Stack Overflow question: Really a thing to ask yourself: "Does this person seem like they are trying to recruit me and make me interested?" I think this is one of the most important bits. If they seem to be taking the attitude that the only one being interviewed is you, then they probably will treat you poorly. Good interviewers understand they have to sell the position as much as the candidate needs to sell themselves. @SethP added: Glassdoor.com is a good web site for researching potential employers. It contains information about how specific companies conduct interviews...

• JavaOne Latin America 2012 Trip Report

  - by reza_rahman

  JavaOne Latin America 2012 was held at the Transamerica Expo Center in Sao Paulo, Brazil on December 4-6. The conference was a resounding success with a great vibe, excellent technical content and numerous world class speakers. Some notable local and international speakers included Bruno Souza, Yara Senger, Mattias Karlsson, Vinicius Senger, Heather Vancura, Tori Wieldt, Arun Gupta, Jim Weaver, Stephen Chin, Simon Ritter and Henrik Stahl. Topics covered included the JCP/JUGs, Java SE 7, HTML 5/WebSocket, CDI, Java EE 6, Java EE 7, JSF 2.2, JMS 2, JAX-RS 2, Arquillian and JavaFX. Bruno Borges and I manned the GlassFish booth at the Java Pavilion on Tuesday and Webnesday. The booth traffic was decent and not too hectic. We met a number of GlassFish adopters including perhaps one of the largest GlassFish deployments in Brazil as well as some folks migrating to Java EE from Spring. We invited them to share their stories with us. We also talked with some key members of the local Java community. Tuesday evening we had the GlassFish party at the Tribeca Pub. The party was definitely a hit and we could have used a larger venue (this was the first time we had the GlassFish party in Brazil). Along with GlassFish enthusiasts, a number of Java community leaders were there. We met some of the same folks again at the JUG leader's party on Wednesday evening. On Thursday Arun Gupta, Bruno Borges and I ran a hands-on-lab on JAX-RS, WebSocket and Server-Sent Events (SSE) titled "Developing JAX-RS Web Applications Utilizing Server-Sent Events and WebSocket". This is the same Java EE 7 lab run at JavaOne San Francisco. The lab provides developers a first hand glipse of how an HTML 5 powered Java EE application might look like. We had an overflow crowd for the lab (at one point we had about twenty people standing) and the lab went very well. The slides for the lab are here: Developing JAX-RS Web Applications Utilizing Server-Sent Events and WebSocket from Reza Rahman The actual contents for the lab is available here. Give me a shout if you need help getting it up and running. I gave two solo talks following the lab. The first was on JMS 2 titled "What’s New in Java Message Service 2". This was essentially the same talk given by JMS 2 specification lead Nigel Deakin at JavaOne San Francisco. I talked about the JMS 2 simplified API, JMSContext injection, delivery delays, asynchronous send, JMS resource definition in Java EE 7, standardized configuration for JMS MDBs in EJB 3.2, mandatory JCA pluggability and the like. The session went very well, there was good Q & A and someone even told me this was the best session of the conference! The slides for the talk are here: What’s New in Java Message Service 2 from Reza Rahman My last talk for the conference was on JAX-RS 2 in the keynote hall. Titled "JAX-RS 2: New and Noteworthy in the RESTful Web Services API" this was basically the same talk given by the specification leads Santiago Pericas-Geertsen and Marek Potociar at JavaOne San Francisco. I talked about the JAX-RS 2 client API, asyncronous processing, filters/interceptors, hypermedia support, server-side content negotiation and the like. The talk went very well and I got a few very kind complements afterwards. The slides for the talk are here: JAX-RS 2: New and Noteworthy in the RESTful Web Services API from Reza Rahman On a more personal note, Sao Paulo has always had a special place in my heart as the incubating city for Sepultura and Soulfy -- two of my most favorite heavy metal musical groups of all time! Consequently, the city has a perpertually alive and kicking metal scene pretty much any given day of the week. This time I got to check out a solid performance by local metal gig Republica at the legendary Manifesto Bar. I also wanted to see a Dio Tribute at the Blackmore but ran out of time and energy... Overall I enjoyed the conference/Sao Paulo and look forward to going to Brazil again next year!

• Oracle at ARM TechCon

  - by Tori Wieldt

  ARM TechCon is a technical conference for hardware and software engineers, Oct. 30-Nov 1 in Santa Clara, California. Days two and three of the conference will be geared towards systems designers and software developers, those interested in building ARM processor-based modules, boards, and systems. It will cover all of the hardware and software, tools, ranging from low-power design, networking and connectivity, open source software, and security. Oracle is a sponsor of ARM TechCon, and will present three Java sessions and a hands-on-lab:  "Do You Like Coffee with Your Dessert? Java and the Raspberry Pi" - The Raspberry Pi, an ARM-powered single board computer running a full Linux distro off an SD card has caused a huge wave of interest among developers. This session looks at how Java can be used on a device such as this. Using Java SE for embedded devices and a port of JavaFX, the presentation includes a variety of demonstrations of what the Raspberry Pi is capable of. The Raspberry Pi also provides GPIO line access, and the session covers how this can be used from Java applications. Prepare to be amazed at what this tiny board can do. (Angela Caicedo, Java Evangelist) "Modernizing the Explosion of Advanced Microcontrollers with Embedded Java" - This session explains why Oracle Java ME Embedded is the right choice for building small, connected, and intelligent embedded solutions, such as industrial control applications, smart sensing, wireless connectivity, e-health, or general machine-to-machine (M2M) functionality---extending your business to new areas, driving efficiency, and reducing cost. The new Oracle Java ME Embedded product brings the benefits of Java technology to microcontroller platforms. It is a full-featured, complete, compliant software runtime with value-add features targeted to the embedded space and has the ability to interface with additional hardware components, remote manageability, and over-the-air software updates. It is accompanied by a feature-rich set of tools free of charge. (Fareed Suliman, Java Product Manager) "Embedded Java in Smart Energy and Healthcare" - This session covers embedded Java products and technologies that enable smart and connect devices in the Smart Energy and Healthcare/Medical industries. (speaker Kevin Lee) "Java SE Embedded Development on ARM Made Easy" - This Hands-on Lab aims to show that developers already familiar with the Java develop/debug/deploy lifecycle can apply those same skills to develop Java applications, using Java SE Embedded, on embedded devices. (speaker Jim Connors) In the Oracle booth #603, you can see the following demos: Industry Solutions with JavaThis exhibit consists of a number of industry solutions and how they can be powered by Java technology deployed on embedded systems.  Examples in consumer devices, home gateways, mobile health, smart energy, industrial control, and tablets all powered by applications running on the Java platform are shown.  Some of the solutions demonstrate the ability of Java to connect intelligent devices at the edge of the network to the datacenter or the cloud as a total end-to-end platform.Java in M2M with QualcommThis station will exhibit a new M2M solutions platform co-developed by Oracle and Qualcomm that enables wireless communications for embedded smart devices powered by Java, and share the types of industry solutions that are possible.  In addition, a new platform for wearable devices based on the ARM Cortex M3 platform is exhibited.Why Java for Embedded?Demonstration platforms will show how traditional development environments, tools, and Java programming skills can be used to create applications for embedded devices.  The advantages that Java provides because of  the runtime's abstraction of software from hardware, modularity and scalability, security, and application portability and manageability are shared with attendees. Drop by and see why Java is an optimal applications platform for embedded systems.
