  In this Issue: Michael Washington, Samuel Jack, Alfred Astort(-2-), Nokola(-2-), Avi Pilosof, Chris Klug, Pete Brown, Laurent Bugnion(-2-), and Jaime Rodriguez(-2-, -3-). Above the Fold: Silverlight: "Sharing resources and styles between projects in Silverlight" Chris Klug WP7: "Windows Phone Application Performance at Silverlight Firestarter" Jaime Rodriguez Training: "Silverlight View Model (MVVM) - A Play In One Act" Michael Washington Shoutouts: Koen Zwikstra announced the availability of the first Silverlight Spy 4 Preview 1 Gavin Wignall announced the Launch of Festive game built with Silverlight 4, hosted on Azure ... free to play. From SilverlightCream.com: Silverlight View Model (MVVM) - A Play In One Act Michael Washington has an interesting take on writing a blog post with this 'play' version of Silverlight View Models and Expression Blend with a heaping dose of Behaviors added in for flavoring. Build a Windows Phone Game in 3 days – Day 1 Samuel Jack is attempting to build a WP7 game in 3 days including downloading the tools and an XNA book... interesting to see where he's headed wth this venture. 4 of 10 - Make sure your finger can hit the target and text is legible Continuing with a series of tips from the folks reviewing apps for the marketplace via Alfred Astort is this number 4 -- touch target size and legible text. 5 of 10 - Give feedback on touch and progress within your UI Alfred Astort's number 5 is also up, and continues the touch discussion with this tip about giving the user feedback on their touch. Fantasia Painter Released for Windows Phone 7 + Tips Nokola took the release of his Fantasia Painter on WP& as an opportunity not only to blog about the fact that we can go buy it, but has a blog full of hints and tips that he gathered while working on it. Games for Windows Phone 7 Resources: Reducing Load Times, RPG Kit; Other Nokola also blogged about the release of the new games education pack, and gives up the cursor he uses in his videos after being asked... The simplest way to do design-time ViewModels with MVVM and Blend. Avi Pilosof attacks the design-time ViewModel issue in Blend with a 'no code' solution. Sharing resources and styles between projects in Silverlight Chris Klug is talking about sharing resources and styles across a large Silverlight project... near and dear to my heart at this moment. Dynamically Generating Controls in WPF and Silverlight Pete Brown has a post up that's generated some interest... creating controls at runtime... and he's demonstrating several different ways for both Silverlight and WPF #twitter for Windows Phone 7 protips (#wp7) Laurent Bugnion was posting these great tips for Twitter for WP7 and rolled all 16 of them up into a blog post... check them and the app out... Increasing touch surface (#wp7dev) Laurent Bugnion's most current post should be of great interest to WP7 devs... providing more touch surface for your user's fat fingers, err, I mean their fat fingerings :) ... great information and samples ... and interesting it is a fail point as listed by Alfred Astort above. Windows Phone Application Performance at Silverlight Firestarter This material from Jaime Rodriguez actually hit prior to his Firestarter presentation, but should be required reading for anyone doing a WP7 app... great Performance tips from the trenches... slide deck, cheat-sheet, and code. UpdateSourceTrigger on Windows Phone data bindings Another post from Jaime Rodriguez actually went through a couple revisions already.. how about a WP7 TextBox that fires notifications to the ViewModel when the text changes? ... would you like a behavior with that? Details on the Push Notification app limits Jaime Rodriguez has yet another required reading post up on Push Notification limits ... what it really entails and how you can be a good WP7 citizen by the way you program your app. Stay in the 'Light!

• Oracle on Oracle: Is that all?

  - by Darin Pendergraft

  On October 17th, I posted a short blog and a podcast interview with Chirag Andani, talking about how Oracle IT uses its own IDM products. Blog link here. In response, I received a comment from reader Jaime Cardoso ([email protected]) who posted: “- You could have talked about how by deploying Oracle's Open standards base technology you were able to integrate any new system in your infrastructure in days. - You could have talked about how by deploying federation you were enabling the business side to keep all their options open in terms of companies to buy and sell while maintaining perfect employee and customer's single view. - You could have talked about how you are now able to cut response times to your audit and security teams into 1/10th of your former times Instead you spent 6 minutes talking about single sign on and self provisioning? If I didn't knew your IDM offer so well I would now be wondering what its differences from Microsoft's offer was. Sorry for not giving a positive comment here but, please your IDM suite is very good and, you simply aren't promoting it well enough” So I decided to send Jaime a note asking him about his experience, and to get his perspective on what makes the Oracle products great. What I found out is that Jaime is a very experienced IDM Architect with several major projects under his belt. Darin Pendergraft: Can you tell me a bit about your experience? How long have you worked in IT, and what is your IDM experience? Jaime Cardoso: I started working in "serious" IT in 1998 when I became Netscape's technical specialist in Portugal. Netscape Portugal didn't exist so, I was working for their VAR here. Most of my work at the time was with Netscape's mail server and LDAP server. Since that time I've been bouncing between the system's side like Sun resellers, Solaris stuff and even worked with Sun's Engineering in the making of an Hierarchical Storage Product (Sun CIS if you know it) and the application's side, mostly in LDAP and IDM. Over the years I've been doing support, service delivery and pre-sales / architecture design of IDM solutions in most big customers in Portugal, to name a few projects: - The first European deployment of Sun Access Manager (SAPO – Portugal Telecom) - The identity repository of 5/5 of the Biggest Portuguese banks - The Portuguese government federation of services project DP: OK, in your blog response, you mentioned 3 topics: 1. Using Oracle's standards based architecture; (you) were able to integrate any new system in days: can you give an example? What systems, how long did it take, number of apps/users/accounts/roles etc. JC: It's relatively easy to design a user management strategy for a static environment, or if you simply assume that you're an <insert vendor here> shop and all your systems will bow to that vendor's will. We've all seen that path, the use of proprietary technologies in interoperability solutions but, then reality kicks in. As an ISP I recall that I made the technical decision to use Active Directory as a central authentication system for the entire IT infrastructure. Clients, systems, apps, everything was there. As a good part of the systems and apps were running on UNIX, then a connector became needed in order to have UNIX boxes to authenticate against AD. And, that strategy worked but, each new machine required the component to be installed, monitoring had to be made for that component and each new app had to be independently certified. A self care user portal was an ongoing project, AD access assumes the client is inside the domain, something the ISP's customers (and UNIX boxes) weren't nor had any intention of ever being. When the Windows 2008 rollout was done, Microsoft changed the Active Directory interface. The Windows administrators didn't have enough know-how about directories and the way systems outside the MS world behaved so, on the go live, things weren't properly tested and a general outage followed. Several hours and 1 roll back later, everything was back working. But, the ISP still had to change all of its applications to work with the new access methods and reset the effort spent on the self service user portal. To keep with the same strategy, they would also have to trust Microsoft not to change interfaces again. Simply by putting up an Oracle LDAP server in the middle and replicating the user info from the AD into LDAP, most of the problems went away. Even systems for which no AD connector existed had PAM in them so, integration was made at the OS level, fully supported by the OS supplier. Sun Identity Manager already had a self care portal, combined with a user workflow so, all the clearances had to be given before the account was created or updated. Adding a new system as a client for these authentication services was simply a new checkbox in the OS installer and, even True64 systems were, for the first time integrated also with a 5 minute work of a junior system admin. True, all the windows clients and MS apps still went to the AD for their authentication needs so, from the start everybody knew that they weren't 100% free of migration pains but, now they had a single point of problems to look at. If you're looking for numbers: - 500K directory entries (users) - 2-300 systems After the initial setup, I personally integrated about 20 systems / apps against LDAP in 1 day while being watched by the different IT teams. The internal IT staff did the rest. DP: 2. Using Federation allows the business to keep options open for buying and selling companies, and yet maintain a single view for both employee and customer. What do you mean by this? Can you give an example? JC: The market is dynamic. The company that's being bought today tomorrow will be sold again. Companies that spread on different markets may see the regulator forcing a sale of part of a company due to monopoly reasons and companies that are in multiple countries have to comply with different legislations. Our job, as IT architects, while addressing the customers and employees authentication services, is quite hard and, quite contrary. On one hand, we need to give access to all of our employees to the relevant systems, apps and resources and, we already have marketing talking with us trying to find out who's a customer of the bough company but not from ours to address. On the other hand, we have to do that and keep in mind we may have to break up all that effort and that different countries legislation may became a problem with a full integration plan. That's a job for user Federation. you don't want to be the one who's telling your President that he will sell that business unit without it's customer's database (making the deal worth a lot less) or that the buyer will take with him a copy of your entire customer's database. Federation enables you to start controlling permissions to users outside of your traditional authentication realm. So what if the people of that company you just bought are keeping their old logins? Do you want, because of that, to have a dedicated system for their expenses reports? And do you want to keep their sales (and pre-sales) people out of the loop in terms of your group's path? Control the information flow, establish a Federation trust circle and give access to your apps to users that haven't (yet?) been brought into your internal login systems. You can still see your users in a unified view, you obviously control if a user has access to any particular application, either that user is in your local database or stored in a directory on the other side of the world. DP: 3. Cut response times of audit and security teams to 1/10. Is this a real number? Can you give an example? JC: No, I don't have any backing for this number. One of the companies I did system Administration for has a SOX compliance policy in place (I remind you that I live in Portugal so, this definition of SOX may be somewhat different from what you're used to) and, every time the audit team says they'll do another audit, we have to negotiate with them the size of the sample and we spend about 15 man/days gathering all the required info they ask. I did some work with Sun's Identity auditor and, from what I've been seeing, Oracle's product is even better and, I've seen that most of the information they ask would have been provided in a few hours with the help of this tool. I do stand by what I said here but, to be honest, someone from Identity Auditor team would do a much better job than me explaining this time savings. Jaime is right: the Oracle IDM products have a lot of business value, and Oracle IT is using them for a lot more than I was able to cover in the short podcast that I posted. I want to thank Jaime for his comments and perspective. We want these blog posts to be informative and honest – so if you have feedback for the Oracle IDM team on any topic discussed here, please post your comments below.

• java.util.ConcurrentModificationException when serializing non thread-safe maps

  - by [email protected]

  We have got some questions related to exceptions thrown during a map serialization like the following one (in this example, for a LRUMap): java.util.ConcurrentModificationExceptionat org.apache.commons.collections.SequencedHashMap$OrderedIterator.next(Unknown Source)at org.apache.commons.collections.LRUMap.writeExternal(Unknown Source)at java.io.ObjectOutputStream.writeExternalData(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java(Inlined CompiledCode))at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java(Inlined CompiledCode))at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java(Inlined CompiledCode))at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java(Compiled Code))at com.tangosol.util.ExternalizableHelper.writeSerializable(ExternalizableHelper.java(InlinedCompiled Code))at com.tangosol.util.ExternalizableHelper.writeObjectInternal(ExternalizableHelper.java(Compiled Code))at com.tangosol.util.ExternalizableHelper.serializeInternal(ExternalizableHelper.java(Compiled Code))at com.tangosol.util.ExternalizableHelper.toBinary(ExternalizableHelper.java(InlinedCompiled Code))at com.tangosol.util.ExternalizableHelper.toBinary(ExternalizableHelper.java(InlinedCompiled Code))at com.tangosol.coherence.servlet.TraditionalHttpSessionModel$OptimizedHolder.serializeValue(TraditionalHttpSessionModel.java(Inlined Compiled Code))at com.tangosol.coherence.servlet.TraditionalHttpSessionModel$OptimizedHolder.getBinary(TraditionalHttpSessionModel.java(Compiled Code)) This is caused because LRUMap is not thread safe, so if another thread is modifying the content of that same map while serialization is in progress, then the ConcurrentModificationException will be thrown. Also, the map must be synchronized. Other structures like java.util.HashMap are not thread safe too. To avoid this kind of problems, it is recommended to use a thread-safe and synchronized map such as java.util.Map, java.util.Hashtable or com.tangosol.util.SafeHashMap. You may also need to use the synchronizedMap(Map) method from Class java.util.Collections.

• Non-English-based programming languages

  - by Jaime Soto

  The University of Antioquia in Colombia teaches its introductory programming courses in Lexico, a Spanish-based, object-oriented .NET language. The intent is to teach programming concepts in the students' native language before introducing English-based mainstream languages. There are many other Non-English-based programming languages and there is even a related question in Stack Overflow. I have several questions regarding these languages: Has anyone on this site learned to program using a non-English-based language? If so, how difficult was the transition to the first English-based language? Is there any research-based evidence that non-English speakers learn programming faster/better using languages with keywords in their native language instead of English-based languages?

• "initialization error: class file has wrong version" message in JDeveloper 10.1.2.x

  - by [email protected]

  The "initialization error: class file has wrong version" has become a somewhat recurrent error message thrown by JDeveloper 10.1.2.x as newer JDKs have been released in the last years. Note that JDeveloper 10.1.2 was developed to run with JDK 1.4.2. The reasons for this error message to be thrown include: A JDK version higher than 1.4.2 is being used and some unexpected incompatibility conflicts can occur because of that Some of the libraries used on the workspace and/or project were compiled with newer JDK version So, it is strongly recommended to use newer JDeveloper versions (10.1.3 - 11g) for newer JDKs. JDeveloper 10.1.2 will be desupported in December 2010 (or later depending on the support contract). Further information about this can be seen at http://www.oracle.com/support/library/brochure/lifetime-support-middleware.pdf

• New Packt Books: APEX & JRockit

  - by [email protected]

    I have received these 2 ebooks from Packt Publkishing and I am currently reviewing them. Both of them look great so far.   Oracle Application Express 3.2 - The Essentials and More First of all, I have to mention that I am new to APEX. I was interested on this product which is a development tool for Web applications on the Oracle Database. As I support JDeveloper and ADF, which are products that work very closely with the Oracle Database and are a rapid development tool as well, it is always interesting and useful to know complementary tools. APEX looks very useful and the book includes many working examples. A more complete review of this book is coming soon. Further information about this book can be seen at Packt.   Oracle JRockit: The Definitive Guide Many of our Oracle Coherence customers run their caches and clusters using JRockit. This JVM has helped us to solve lots of Service Requests. It is a really reliable, fast and stable JVM. It works great on both development and production environments with big amounts of data, concurrency, multi-threading and many other factors that can make a JVM crash. I must also mention JRockit Mission Control (JRMC), which is a great tool for management and monitoring. I really recommend it. As a matter of fact, some months ago, I created a document entitled "How to Monitor Coherence-Based Applications using JRockit Mission Control" (Doc Id 961617.1) on My Oracle Support. Also, the JRockit Runtime Analyzer (JRA) and it successor of newer versions, the JRockit Flight Recorder (JFR) are deeply reviewed. This book contains very clear and complete information about all this and more. I will post an entry with a more complete review soon (and will probably post an entry about Coherence monitoring with JRMC soon too). Further information about this book can be seen at Packt.

• Bohemia Interactive's bio2s format

  - by Jaime Soto

  Does anyone have specifications for the bio2s scripting language from Bohemia Interactive? They develop Operation Flashpoint, Armed Assault (ArmA), and Virtual Battlespace. These scripts are sometimes called O2 or Oxygen scripts and are used in their terrain and modeling tools. Oxygen is Bohemia Interactive's modeling tool. I found additional examples of the format in this VBS2 tutorial and this ArmA forum thread. EDIT: I clarified the purpose of the bio2s format and provided some links to examples.

• C/C++: Who uses the logical operator macros from iso646.h and why?

  - by Jaime Soto

  There has been some debate at work about using the merits of using the alternative spellings for C/C++ logical operators in iso646.h: and && and_eq &= bitand & bitor | compl ~ not ! not_eq != or || or_eq |= xor ^ xor_eq ^= According to Wikipedia, these macros facilitate typing logical operators in international (non-US English?) and non-QWERTY keyboards. All of our development team is in the same office in Orlando, FL, USA and from what I have seen we all use the US English QWERTY keyboard layout; even Dvorak provides all the necessary characters. Supporters of using the iso646.h macros claim we should them because they are part of the C and C++ standards. I think this argument is moot since digraphs and trigraphs are also part of these standards and they are not even supported by default in many compilers. My rationale for opposing these macros in our team is that we do not need them since: Everybody on our team uses the US English QWERTY keyboard layout; C and C++ programming books from the US barely mention iso646.h, if at all; and new developers may not be familiar with iso646.h (this is expected if they are from the US). /rant Finally, to my set of questions: Does anyone in this site use the iso646.h logical operator macros? Why? What is your opinion about using the iso646.h logical operator macros in code written and maintained on US English QWERTY keyboards? Is my digraph and trigraph analogy a valid argument against using iso646.h with US English QWERTY keyboard layouts? EDIT: I missed two similar questions in StackOverflow: Is anybody using the named boolean operators? Which C++ logical operators do you use: and, or, not and the ilk or C style operators? why?

• "Oracle Enterprise Manager Grid Control Advanced OEM Techniques for the Real World" Book - My Humble Review

  - by cristobal.soto(at)oracle.com

  After reviewing this book, I am really amazed with it. I really recommend it, specially if you work with these tools (BPEL, SOA Suite and/or OSB), if you are a SOA Architect and/or if your work is focused on production environments.This book provides valuable and useful information for monitoring and automation tasks.In the books is very clearly explained and with screenshots (which makes it even easier to read, understand and follow) how to perform several tasks that are necessary to keep a correct performance on the production environments and the subtasks that must be executed on them.The test sections on chapters 3, 10 and 13 (SOAP tests for partner links and BPEL processes, service tests on web applications, and SOAP test OSB proxy and business service endpoints) look specially interesting for me and I really liked to see that there is special emphasis on the use of WebLogic Server as well.For further information and order the book, please go to the Packt Publishing web site.

• "Oracle Coherence 3.5" Book - My Humble Review

  - by [email protected]

    After reviewing the book in more detail I say again that it is a great guide for sure. Lots of important concepts that sometimes can be somewhat confusing are deeply reviewed, including all types of caching schemes and backing maps, and the cache topologies with their corresponding performances and very useful "When to use it?" sections. Some functionalities that are very desirable or used a lot are reviewed with examples and best practices of implementation, including: Data affinity Querying Pagination Indexes Aggregations Event processing, listening and triggering Data persistence Security Regarding the networking and architecture topics, Coherence*Extend is exhaustively reviewed, including C++ and .NET clients, with very good tips and examples, even including source codes. Personally, I am also glad to see that the address providers (<address-provider> tag), new feature in Coherence 3.5 which is a way to programmatically provide well-known addresses in order to connect to the cluster, is mentioned on the book, because it provides new functionalities to satisfy some special configuration requirements for example: Provide a way to switch extend nodes in cases of failure Implement custom load balancing algorithms and/or dynamic discovery of TCP/IP connection acceptors Dynamically assign TCP address and port settings when binding to a server socket Another very interesting and useful section is the "Coherent Bank Sample Application", which is a great tutorial, useful to understand how Coherence interacts with third party products establishing a clear integration with them, including the use of non-Oracle products like MS Visual Studio.

• switch views using a button, going to a table view, iphone

  - by Jaime Rae

  My program has 4 buttons and each button calls a different table view. That works fine, but my problem is, the view controller I'm using brings up a table view that covers up my navigation bar and my tab bar. I need to replace that coding with something that will bring up a table and not cover up my nav and tab bars. Here is the coding I'm using: -(IBAction)buttonNorthWest { NorthWestViewController *nwController = [[NorthWestViewController alloc] initWithNibName:@"NorthWestView" bundle:nil]; self.nwViewController = nwController; [self.view insertSubview:nwViewController.view atIndex:0]; [self presentModalViewController:nwViewController animated:YES]; [nwController release]; } The [self presentModalViewController....] is the problem. Does anyone know how I can replace that code with something that keeps my nav and tab bars? Thanks, Jaime

• Should devs, testers and business users have one unified test script?

  - by Carlos Jaime C. De Leon

  In development, I would normally have my own test scripts that would document the data, scenarios and execution steps that I plan to test; this is my dev test plan. When the functionality has been deployed to Test, testers test it using their own test script that they wrote. In UAT, the business user then tests using their own test plan. In retrospect, it looks like this provides a better coverage, with dev tests having a mix of black and white box testing, while testers and business users focus on black box testing. But on the other hand, this brings up distinct test cases that only are executed per stage (ie. some cases which testers thought of are only executed on Test stage) and it would like the dev missed it, which makes it a finding/bug. Is it worth consolidating the test scripts from the start? Thus using one unified test script, or is it abit difficult to do this upfront?
