Does it seem an adventure? Well it is and I will tell you how I came to have this international experience. Dzien Dobry! My name is Wojciech Jurojc, I am Polish and I am currently a Business Development Consultant within Oracle, based in Prague. I joined Oracle on the 1st of August 2011. I graduated in 2010 and obtained 2 Masters Degrees in Political Science and Economics. I would like to tell you more about my past and how I joined Oracle. In 2005 I began studying at the Faculty of Political Sciences Gdansk University. In 2008, I obtained a Bachelors Degree. During these three years I had the opportunity to go to England twice, where I worked as a Bartender, first in Blackpool and then in Manchester. This allowed me to improve my language skills and become more confident. In the meantime, I joined the International Student Organization-AIESEC, where I was organized conferences and conducted student projects. Also I met a mass of interesting people from around the world. After graduation in 2008, I was able to get an Internship within a big company in Poland. I worked there as an Intern in the Purchase Department. That was my first adventure within a corporate environment. I learnt a lot about purchasing processes and negotiations. In September 2008, I started studying two Masters Faculties: Political Science and Economics. It was very difficult, but it was not impossible. Over the next two years of studying I was able to go on a three month internship to India where I worked as a Marketing Assistant in an NGO. I was travelling around northern India and did presentations to the academic community about green energy and environmental projects. I had the opportunity to visit Nepal and walked in the Himalayas. That was a huge experience as well as a cultural shock. It taught me how to deal with many problems and to appreciate what I have. At the end of 2009 I was working as a Marketing Assistant for a Leasing company, where I learnt useful sales knowledge and improved my objection handling skills. In July 2010, I graduated with a double Masters and found a job in Thailand as Sales Representative in an IT company. I worked in Thailand until the end of January 2011. Besides that, I was working in an International company with interesting people and I had the opportunity to travel around Thailand and visit Cambodia. After this adventure I started looking for jobs in Europe where I could further develop my sales skills. I found Oracle and I don’t regret this decision which I made. I am currently working in Prague in an international Hardware team and I know that is not the end of my adventures. At this moment, I am working in a team of 12 members. Ten of them are based in Prague and 2 others are based in Russia. We come from different countries such as: Czech Republic, Russia, Ukraine, Turkey, Slovakia and Kazakhstan. I am working on the Polish market, cooperating with our Hardware customers and partners. What do I enjoy the most about my job? I enjoy every challenge that I face in my daily activities as there are always new experiences for me and new things that I learn. As part of Oracle, I gain international exposure and therefore more career opportunities to explore. I have planned my next step for the career path I dream of and I am currently working on it. I recommend you check our Career Page if you’re looking for an international career. If you want to find out more about our job opportunities, follow us on https://campus.oracle.com .

• Pirates, Treasure Chests and Architectural Mapping

  Pirate 1: Why do pirates create treasure maps? Pirate 2: I do not know.Pirate 1: So they can find their gold. Yes, that was a bad joke, but it does illustrate a point. Pirates are known for drawing treasure maps to their most prized possession. These documents detail the decisions pirates made in order to hide and find their chests of gold. The map allows them to trace the steps they took originally to hide their treasure so that they may return. As software engineers, programmers, and architects we need to treat software implementations much like our treasure chest. Why is software like a treasure chest? It cost money, time,  and resources to develop (Usually) It can make or save money, time, and resources (Hopefully) If we operate under the assumption that software is like a treasure chest then wouldn’t make sense to document the steps, rationale, concerns, and decisions about how it was designed? Pirates are notorious for documenting where they hide their treasure.  Shouldn’t we as creators of software do the same? By documenting our design decisions and rationale behind them will help others be able to understand and maintain implemented systems. This can only be done if the design decisions are correctly mapped to its corresponding implementation. This allows for architectural decisions to be traced from the conceptual model, architectural design and finally to the implementation. Mapping gives software professional a method to trace the reason why specific areas of code were developed verses other options. Just like the pirates we need to able to trace our steps from the start of a project to its implementation,  so that we will understand why specific choices were chosen. The traceability of a software implementation that actually maps back to its originating design decisions is invaluable for ensuring that architectural drifting and erosion does not take place. The drifting and erosion is prevented by allowing others to understand the rational of why an implementation was created in a specific manor or methodology The process of mapping distinct design concerns/decisions to the location of its implemented is called traceability. In this context traceability is defined as method for connecting distinctive software artifacts. This process allows architectural design models and decisions to be directly connected with its physical implementation. The process of mapping architectural design concerns to a software implementation can be very complex. However, most design decision can be placed in  a few generalized categories. Commonly Mapped Design Decisions Design Rationale Components and Connectors Interfaces Behaviors/Properties Design rational is one of the hardest categories to map directly to an implementation. Typically this rational is mapped or document in code via comments. These comments consist of general design decisions and reasoning because they do not directly refer to a specific part of an application. They typically focus more on the higher level concerns. Components and connectors can directly be mapped to architectural concerns. Typically concerns subdivide an application in to distinct functional areas. These functional areas then can map directly back to their originating concerns.Interfaces can be mapped back to design concerns in one of two ways. Interfaces that pertain to specific function definitions can be directly mapped back to its originating concern(s). However, more complicated interfaces require additional analysis to ensure that the proper mappings are created. Depending on the complexity some Behaviors\Properties can be translated directly into a generic implementation structure that is ready for business logic. In addition, some behaviors can be translated directly in to an actual implementation depending on the complexity and architectural tools used. Mapping design concerns to an implementation is a lot of work to maintain, but is doable. In order to ensure that concerns are mapped correctly and that an implementation correctly reflects its design concerns then one of two standard approaches are usually used. All Changes Come From ArchitectureBy forcing all application changes to come through the architectural model prior to implementation then the existing mappings will be used to locate where in the implementation changes need to occur. Allow Changes From Implementation Or Architecture By allowing changes to come from the implementation and/or the architecture then the other area must be kept in sync. This methodology is more complex compared to the previous approach.  One reason to justify the added complexity for an application is due to the fact that this approach tends to detect and prevent architectural drift and erosion. Additionally, this approach is usually maintained via software because of the complexity. Reference:Taylor, R. N., Medvidovic, N., & Dashofy, E. M. (2009).

• Creating a 2D Line Branch (Part 2)

  - by Danran

  Yesterday i asked this question on how to create a 2D line branch; Creating a 2D Line Branch And thanks to the answered provided, i now have this nice looking main branch; *coloured to show the different segments in the final item. Now is the time now to branch things off as discussed in the article; http://drilian.com/2009/02/25/lightning-bolts/ Again however i am confused as to the meaning of the following pseudo code; splitEnd = Rotate(direction, randomSmallAngle)*lengthScale + midPoint; I'm unsure how to actually rotate this correctly. In all honesty i'm abit unsure what to-do completely at this part, "splitEnd" will be a Vector3, so whatever happens in the rotate function must then return some form of directional rotation which is then * by a scale to create length and then added to the midPoint. I'm not sure. If someone could explain what i'm meant to be doing in this part that would be really grateful.

• Tiled perlin/value noise texture with (2^n)+1 size

  - by tobi

  Actually what I have in mind is value noise I think, but what I am going to ask applies to both of them. It is known that if you want to produce tiled texture by using the perlin/value noise, the size of the texture should be specified as the power of 2 (2^n). Without any modifications to the algorithm when you use the size of (2^n)+1 the texture cannot be tiled anymore, so I am wondering whether it is possible (by modifying the algorithm somehow) to generate such tiling texture with the size of (2^n)+1. The article (from which I have my implementation) is here: http://devmag.org.za/2009/04/25/perlin-noise/ I am aware that I can produce texture with 2^n size and just copy twice the last column/row from the ends to make it (2^n)+1, but I don't want to, because such repetitions are visible too much.

• New Endpoint options that enable additional application patterns

  - by kaleidoscope

  The two communication-related capabilities:  a) inter-role communication and b) external endpoints on worker roles enable new application patterns in Windows Azure-hosted services. Inter-role Communication - A common application pattern enabled by this is client-server, where the server could be an application such as a database or a memory cache. External Endpoints on Worker Roles - A common application type enabled by this is a self-hosted Internet-exposed service, such as a custom application server.

• Multiple Passwords on One Account

  - by user110789

  I'd like to join three ideas into one interesting and sometimes useful feature. There was a question about using multiple passwords earlier this year, but it didn't receive much attention. I'd like to ask the question again after showing an interesting and new way to use the feature. The three original posts I found to be interestingly combined were: (1) Multiple passwords per user (2) http://blog.littleimpact.de/index.php/2009/09/14/automatic-encryption-of-home-directories-using-truecrypt-62-and-pam_exec/ (3) http://www.truecrypt.org/docs/hidden-volume Basically I'd like to login to my account with two passwords and depending on the password I use, I would get a different content in my home directory. In a way I would get a cryptographically hidden account into my system. So the question is, is it possible to allow multiple passwords to log on to Ubuntu/Linux for the same user?

• FreeBSD performance tuning. Sysctls, loader.conf, kernel.

  - by SaveTheRbtz

  I wanted to share knowledge of tuning FreeBSD via sysctls, so i'm posting them with comments. Based on Igor Sysoev (author of nginx) presentation about FreeBSD tuning up to 100,000-200,000 active connections. Sysctls are for 7.x FreeBSD. Since 7.2 amd64 some of them are tuned well by default. Prior 7.0 some of them are boot only (set via /boot/loader.conf) or does not exist at all.

I wanted to thank FreeBSD community, especially author of nginx - Igor Sysoev, nginx-ru@ and FreeBSD-performance@ mailing lists for providing useful information about FreeBSD tuning. So here is the question: What tunings are you using on yours FreeBSD servers? You can also post your /etc/sysctl.conf, /boot/loader.conf, kernel options, etc with description of its' meaning (do not copy-paste from sysctl -d). Don't forget to specify server type (web, smb, gateway, etc) Let's share experience!

• Uploading multiple images through Tumblr API

  - by Joseph Carrington

  I have about 300 images I want to upload to my new Tumblr account, becuase my old wordpress site got hacked and I no longer wish to use wordpress. I uploaded one image a day for 300 days, and I'd like to be able to take these images and upload them to my tumblr site using the api. The images are currently local, stored in /images/. They all have the date they were uploaded as the first ten characters of the filename, (01-01-2009-filename.png) and I went to send this date parameter along as well. I want to be able to see the progress of the script by outputting the responses from the API to my error_log. Here is what I have so far, based on the tumblr api page. // Authorization info $tumblr_email = '[email protected]'; $tumblr_password = 'password'; // Tumblr script parameters $source_directory = "images/"; // For each file, assign the file to a pointer here's the first stumbling block. How do I get all of the images in the directory and loop through them? Once I have a for or while loop set up I assume this is the next step $post_data = fopen(dir(__FILE__) . $source_directory . $current_image, 'r'); $post_date = substr($current_image, 0, 10); // Data for new record $post_type = 'photo'; // Prepare POST request $request_data = http_build_query( array( 'email' => $tumblr_email, 'password' => $tumblr_password, 'type' => $post_type, 'data' => $post_data, 'date' => $post_date, 'generator' => 'Multi-file uploader' ) ); // Send the POST request (with cURL) $c = curl_init('http://www.tumblr.com/api/write'); curl_setopt($c, CURLOPT_POST, true); curl_setopt($c, CURLOPT_POSTFIELDS, $request_data); curl_setopt($c, CURLOPT_RETURNTRANSFER, true); $result = curl_exec($c); $status = curl_getinfo($c, CURLINFO_HTTP_CODE); curl_close($c); // Output response to error_log error_log($result); So, I'm stuck on how to use PHP to read a file directory, loop through each of the files, and do things to the name / with the file itself. I also need to know how to set the data parameter, as in choosing multi-part / formdata. I also don't know anything about cURL.

• Debugging Messaging Exception

  - by rizza

  We have a batch program that incorporates JavaMail 1.2 that sends emails. In our development environment, we haven't got the chance to encounter the above mentioned exception. But in the client's environment, they had experienced this a lot of times with the following error trace: javax.mail.MessagingException: 550 Requested action not taken: NUL characters are not allowed. at com.sun.mail.smtp.SMTPTransport.issueCommand (SMTPTransport.java: 879) at com.sun.mail.smtp.SMTPTransport.finishData (SMTPTransport.java: 820) at com.sun.mail.smtp.SMTPTransport.sendMessage (SMTPTransport.java: 322) ... I'm not sure if this is connected to my problem, http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4697158. But trying JavaMail 1.4.2, I see that the content transfer encoding of the email is still 7bit, so I'm not sure if using JavaMail 1.4.2 could solve the problem. Please take note that I could only do testing in our development environment that hasn't been able to replicate this. With the above exception, how would i know if this is from the sender or the receiver side? What debugging steps could you suggest? EDIT: Here is a DEBUG of the actual sending (masked some information): DEBUG: not loading system providers in &lt;java.home&gt;</a>/lib DEBUG: not loading optional custom providers file: /META-INF/javamail.providers DEBUG: successfully loaded default providers DEBUG: Tables of loaded providers DEBUG: Providers Listed By Class Name: {com.sun.mail.smtp.SMTPTransport=javax.mail.Provider[TRANSPORT,smtp,com.sun.mail.smtp.SMTPTransport,Sun Microsystems, Inc], com.sun.mail.imap.IMAPStore=javax.mail.Provider[STORE,imap,com.sun.mail.imap.IMAPStore,Sun Microsystems, Inc], com.sun.mail.pop3.POP3Store=javax.mail.Provider[STORE,pop3,com.sun.mail.pop3.POP3Store,Sun Microsystems, Inc]} DEBUG: Providers Listed By Protocol: {imap=javax.mail.Provider[STORE,imap,com.sun.mail.imap.IMAPStore,Sun Microsystems, Inc], pop3=javax.mail.Provider[STORE,pop3,com.sun.mail.pop3.POP3Store,Sun Microsystems, Inc], smtp=javax.mail.Provider[TRANSPORT,smtp,com.sun.mail.smtp.SMTPTransport,Sun Microsystems, Inc]} DEBUG: not loading optional address map file: /META-INF/javamail.address.map DEBUG: getProvider() returning javax.mail.Provider[TRANSPORT,smtp,com.sun.mail.smtp.SMTPTransport,Sun Microsystems, Inc] DEBUG SMTP: useEhlo true, useAuth false DEBUG: SMTPTransport trying to connect to host "nnn.nnn.n.nnn", port nn DEBUG SMTP RCVD: 220 xxxx.xxxxxxxxxxx.xxx SMTP; Mon, 23 Mar 2009 15:18:57 +0800 DEBUG: SMTPTransport connected to host "nnn.nnn.n.nnn", port: nn DEBUG SMTP SENT: EHLO xxxxxxxxx DEBUG SMTP RCVD: 250 xxxx.xxxxxxxxxxx.xxx Hello DEBUG SMTP: use8bit false DEBUG SMTP SENT: MAIL FROM:<a href="newmsg.cgi?mbx=Main&[email protected]">&lt;[email protected]&gt;</a> DEBUG SMTP RCVD: 250 <a href="newmsg.cgi?mbx=Main&[email protected]">&lt;[email protected]&gt;</a>...

• Landscape orientation for UITabBarController?

  - by gingersnap

  The UITabBarController does not allow landscape orientation. So I used a subclass of UITabBarContoller (called RotatingTabBarController). Its sole purpose it to allow rotation by returning YES to shouldAutorotateToInterfaceOrientation call. The problem is that when you rotate the iPhone in simulator it gives the following malloc error. malloc: *** error for object 0x3888000: pointer being freed was not allocated *** set a breakpoint in malloc_error_break to debug I am using 3.0 SDK with Xcode 3.2 on Snow Leopard. I set a breakpoint in malloc_error_break but I can not trace it back to my code. Is there something I can do to make this error go away? Here is the RotatingTabBarController class: #import <UIKit/UIKit.h> @interface RotatingTabBarController : UITabBarController { } @end @implementation RotatingTabBarController -(BOOL)shouldAutorotateToInterfaceOrientation:UIInterfaceOrientation)interfaceOrientation { return YES; } @end Update: I tried the same with a category. But it gives the same malloc error. // UITabBarController+Rotation.h @interface UITabBarController (rotation) - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation; @end // UITabBarController+Rotation.m #import "UITabBarController+Rotation.h" @implementation UITabBarController (rotation) - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } @end Backtrace [Session started at 2009-09-05 12:13:19 -0400.] Untitled(992,0xa06d9500) malloc: *** error for object 0x2024000: pointer being freed was not allocated *** set a breakpoint in malloc_error_break to debug Untitled(992,0xa06d9500) malloc: *** error for object 0x2014000: pointer being freed was not allocated *** set a breakpoint in malloc_error_break to debug [Session started at 2009-09-05 12:13:27 -0400.] GNU gdb 6.3.50-20050815 (Apple version gdb-1344) (Fri Jul 3 01:19:56 UTC 2009) Copyright 2004 Free Software Foundation, Inc.

• how to Use JAXWS/JAXB rename the parameter

  - by shrimpy

  I use CXF(2.2.3) to compile the Amazon Web Service WSDL (http://s3.amazonaws.com/ec2-downloads/2009-07-15.ec2.wsdl) But got error as below. Parameter: snapshotSet already exists for method describeSnapshots but of type com.amazonaws.ec2.doc._2009_07_15.DescribeSnapshotsSetType instead of com.amazonaws.ec2.doc._2009_07_15.DescribeSnapshotsSetResponseType. Use a JAXWS/JAXB binding customization to rename the parameter. The conflict was due to the data type show below: <xs:complexType name="DescribeSnapshotsType"> <xs:sequence> <xs:element name="snapshotSet" type="tns:DescribeSnapshotsSetType"/> </xs:sequence> </xs:complexType> <xs:complexType name="DescribeSnapshotsResponseType"> <xs:sequence> <xs:element name="requestId" type="xs:string"/> <xs:element name="snapshotSet" type="tns:DescribeSnapshotsSetResponseType"/> </xs:sequence> </xs:complexType> I create a binding file try to address the issue...but it didn`t do the job <jaxws:bindings xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" wsdlLocation="EC2_2009-07-15.wsdl" xmlns="http://java.sun.com/xml/ns/jaxws" xmlns:jxb="http://java.sun.com/xml/ns/jaxb" xmlns:jaxws="http://java.sun.com/xml/ns/jaxws"> <enableWrapperStyle>false</enableWrapperStyle> <jaxws:bindings node="wsdl:definitions/wsdl:types/xs:schema[@targetNamespace='http://ec2.amazonaws.com/doc/2009-07-15/']"> <jxb:bindings node="xs:complexType[@name='tns:DescribeSnapshotsType']//xs:element[@name='snapshotSet']"> <jxb:property name="snapshotRequestSet"/> </jxb:bindings> <jxb:bindings node="xs:complexType[@name='DescribeSnapshotsResponseType']//xs:element[@name='snapshotSet']"> <jxb:property name="snapshotResponseSet"/> </jxb:bindings> </jaxws:bindings> </jaxws:bindings> And the command i used, was like below <wsdlOptions> <wsdlOption> <wsdl>${basedir}/src/main/resources/wsdl/EC2_2009-07-15.wsdl</wsdl> <extraargs> <extraarg>-b</extraarg> <extraarg>${basedir}/src/main/resources/wsdl/Bindings_EC2_2009-07-15.xml</extraarg> </extraargs> </wsdlOption> </wsdlOptions> What is wrong with my code????

• iPhone static libraries: How to hide instance variable

  - by Frenzy

  I'm creating a static library to share using the following guide: http://www.amateurinmotion.com/articles/2009/02/08/creating-a-static-library-for-iphone.html In one of the functions, I return a "SomeUIView" which is a subclass of UIView and is defined in the public header, however I don't want to expose the internal instance variable of SomeUIView in the public header. I've tried using categories for a private internal header file for SomeUIView, but I keep running into "Duplicate interface declaration for class 'SomeUIView'". Does anyone know how to do this? Thanks!

• Using Monotouch with Google .NET APIs

  - by Bryan

  I am using Mike Bluestein's article, http://mikebluestein.wordpress.com/2009/09/27/using-monotouch-with-the-net-library-for-the-google-data-api/, to build an application that communicates with the google APIs. When I try to add references to my project, the imported projects say "incompatible target framework: v2.0". I can change version to 1.0, 3.0, or 3.5 with the same results. If I add the .dll to the monotouch project I get a compilation error - monotouch failed with no output 134. Any suggestions?

• Vim syntax highlighting not working (but works in gvim?)

  I've followed all instructions given on this site with an empty .vim folder, but for some reason, python highlighting is not working on my system. It only highlights the comments and a few variables - nothing like the picture. http://concisionandconcinnity.blogspot.com/2009/07/vim-part-i-improved-python-syntax.html Is there some other setting I am forgetting? I'm also using ubuntu 10.04 if that matters. A weird other note - it works in gvim, but not vim?

• mysql never releases memory

  - by Ishu

  I have a production server clocking about 4 million page views per month. The server has got 8GB of RAM and mysql acts as a database. I am facing problems in handling mysql to take this load. I need to restart mysql twice a day to handle this thing. The problem with mysql is that it starts with some particular occupation, the memory consumed by mysql keeps on increasing untill it reaches the maximum it can consume and then mysql stops responding slowly or does not respond at all, which freezes the server. All my tables are indexed properly and there are no long queries. I need some one to help on how to go about debugging what to do here. All my tables are myisam. I have tried configuring the parameters key_buffer etc but to no rescue. Any sort of help is greatly appreciated. Here are some parameters which may help. mysql --version mysql Ver 14.12 Distrib 5.0.77, for redhat-linux-gnu (i686) using readline 5.1 mysql> show variables;

• Shawn Wildermuth violating MVVM in MSDN article?

  - by rasx

  This may be old news but back in March 2009, Shawn Wildermuth, his article, “Model-View-ViewModel In Silverlight 2 Apps,” has a code sample that includes DataServiceEntityBase: // COPIED FROM SILVERLIGHTCONTRIB Project for simplicity /// <summary> /// Base class for DataService Data Contract classes to implement /// base functionality that is needed like INotifyPropertyChanged. /// Add the base class in the partial class to add the implementation. /// </summary> public abstract class DataServiceEntityBase : INotifyPropertyChanged { /// <summary> /// The handler for the registrants of the interface's event /// </summary> PropertyChangedEventHandler _propertyChangedHandler; /// <summary> /// Allow inheritors to fire the event more simply. /// </summary> /// <param name="propertyName"></param> protected void FirePropertyChanged(string propertyName) { if (_propertyChangedHandler != null) { _propertyChangedHandler(this, new PropertyChangedEventArgs(propertyName)); } } #region INotifyPropertyChanged Members /// <summary> /// The interface used to notify changes on the entity. /// </summary> event PropertyChangedEventHandler INotifyPropertyChanged.PropertyChanged { add { _propertyChangedHandler += value; } remove { _propertyChangedHandler -= value; } } #endregion What this class implies is that the developer intends to bind visuals directly to data (yes, a ViewModel is used but it defines an ObservableCollection of data objects). Is this design diverging too far from the guidance of MVVM? Now I can see some of the reasons why Shawn would go this way: what Shawn can do with DataServiceEntityBase is this sort of thing (which is intimate with the Entity Framework): // Partial Method to support the INotifyPropertyChanged interface public partial class Game : DataServiceEntityBase { #region Partial Method INotifyPropertyChanged Implementation // Override the Changed partial methods to implement the // INotifyPropertyChanged interface // This helps with the Model implementation to be a mostly // DataBound implementation partial void OnDeveloperChanged() { base.FirePropertyChanged("Developer"); } partial void OnGenreChanged() { base.FirePropertyChanged("Genre"); } partial void OnListPriceChanged() { base.FirePropertyChanged("ListPrice"); } partial void OnListPriceCurrencyChanged() { base.FirePropertyChanged("ListPriceCurrency"); } partial void OnPlayerInfoChanged() { base.FirePropertyChanged("PlayerInfo"); } partial void OnProductDescriptionChanged() { base.FirePropertyChanged("ProductDescription"); } partial void OnProductIDChanged() { base.FirePropertyChanged("ProductID"); } partial void OnProductImageUrlChanged() { base.FirePropertyChanged("ProductImageUrl"); } partial void OnProductNameChanged() { base.FirePropertyChanged("ProductName"); } partial void OnProductTypeIDChanged() { base.FirePropertyChanged("ProductTypeID"); } partial void OnPublisherChanged() { base.FirePropertyChanged("Publisher"); } partial void OnRatingChanged() { base.FirePropertyChanged("Rating"); } partial void OnRatingUrlChanged() { base.FirePropertyChanged("RatingUrl"); } partial void OnReleaseDateChanged() { base.FirePropertyChanged("ReleaseDate"); } partial void OnSystemNameChanged() { base.FirePropertyChanged("SystemName"); } #endregion } Of course MSDN code can seen as “toy code” for educational purposes but is anyone doing anything like this in the real world of Silverlight development?

• Google App Engine + AdWords API: java.lang.NoClassDefFoundError: javax/xml/soap/SOAPException

  - by Konrad

  Hi all, I know a lot so far about this exception. But I am wondering, if any of you tried to use AdWords API on GAE. AdWords uses Axis as underlying WS library, which do not work on GAE and unfortunately I cannot find solution to make it working. I tried already this: http://dev.bizo.com/2009/04/calling-soap-web-services-on-google-app.html Does any of you know if there is a way to use AdWords API on GAE with Java? Thanks in advance for any help Konrad
