  • How to center and scale Silverlight applications using ViewBox control

    - by Jacek Ciereszko
    There are many ways to make your application scalable in Web Browser window and align it in the center. Usually we use two Grid controls to align and panel control (like Canvas) to scale our apps. Not the best solution <UserControl … >     <Grid x:Name="LayoutRoot" Background="White">         <Grid HorizontalAlignment="Center" VerticalAlignment="Center">             <Canvas x:Name="scalePanel" VerticalAlignment="Top" HorizontalAlignment="Center">                 …             </Canvas>         </Grid>     </Grid> </UserControl>               The example above usually works but there are better ways. How? Use ViewBox. ViewBox control contains scale mechanisms with some stretching options. So ViewBox together with Grid control is all what we need to align and scale our applications. Good solution <UserControl … >     <Grid x:Name="LayoutRoot" Background="White">         <Viewbox>             ...         </Viewbox>     </Grid> </UserControl> How to find ViewBox control For those applications created in Silverlight 4, ViewBox is available in plug-in. For applications created in Silverlight 3 you can find it in Microsoft Silverlight Toolkit. Demo Let’s create a simple application that will contain: Button, TextBlock and red Rectangle. It will also have some Margin settings. This application won’t be in the center of window and it will not scale. <UserControl … >     <Grid x:Name="LayoutRoot">         <Grid Margin="100, 50, 100, 20">                 <StackPanel Orientation="Horizontal">                     <Button Width="100" Height="100" Content="test"/>                     <TextBlock Text="Button" Width="100" Height="100" />                     <Rectangle Width="100" Height="100" Fill="Red"/>                 </StackPanel>         </Grid> </Grid> </UserControl>   Run demo: RUN But If we use ViewBox control, we will got centered and always scaled application.    <Grid x:Name="LayoutRoot">         <Viewbox>             <Grid Margin="100, 50, 100, 20">                     <StackPanel Orientation="Horizontal">                         <Button Width="100" Height="100" Content="test"/>                         <TextBlock Text="bottom" Width="100" Height="100" />                         <Rectangle Width="100" Height="100" Fill="Red"/>                     </StackPanel>             </Grid>         </Viewbox>     </Grid> Link to application: RUN (try to resize application’s window) Link to source code: SilverlightCenterApplication.zip References ViewBox for Silverlight 3 http://silverlight.codeplex.com/    Polish version: http://jacekciereszko.pl/2010/05/jak-wysrodkowac-i-skalowac-aplikacje.html Jacek Ciereszko

  • LIMBO fails on startup with Internal errors - invalid parameters received

    - by user61262
    I installed LIMBO from the Humble Bundle V and as far as I am aware, this has wine packaged with it (I also installed the latest from the repo's in case is was because of that). However the game doesn't even start and fails with the message: Wine Program Error Internal errors - invalid parameters received. Is there a way to log the error or does anyone know why this happens? This question was asked previously but it seems to have disappeared. My Graphics cards is a Geforece GT 250 Cheers ice. [edit: Wine outputs the following error: wine /opt/limbo/support/limbo/drive_c/Program\ Files/limbo/limbo.exe fixme:system:SystemParametersInfoW Unimplemented action: 59 (SPI_SETSTICKYKEYS) fixme:system:SystemParametersInfoW Unimplemented action: 53 (SPI_SETTOGGLEKEYS) fixme:system:SystemParametersInfoW Unimplemented action: 51 (SPI_SETFILTERKEYS) fixme:win:EnumDisplayDevicesW ((null),0,0x32f580,0x00000000), stub! err:x11settings:X11DRV_ChangeDisplaySettingsEx No matching mode found 1920x1080x32 @60!

  • Live vom Oracle Partner Day 2012 in Frankfurt

    - by A&C Redaktion
    Frankfurt a. M. gegen 11:30 UhrCharmante Idee, mit einem Welcome-Lunch in den Oracle Partner Day 2012 zu starten. So kann man bei einem Snack auch gleich die beeindruckende Atmosphäre der Commerzbank Arena auf sich wirken lassen und ist, ehe man sich versieht, mit dem nebenstehenden Geschäftsführer, einer Managerin und zwei Vertriebsmitarbeitern in ein Gespräch über die jeweils letzten Stadionbesuche verwickelt. Überall fröhliches Wiedersehen, viele haben sich das letzte Mal vor genau einem Jahr getroffen, im Radisson Blu, beim OPN Day Satellite. So, die Masse setzt sich in Bewegung – auf geht’s zur Eröffnung: Silvia Kaske fängt an! 13:45 Uhr Die Keynotes waren mal wieder ein thematischer Rundumschlag – und ein kleines Who-is-Who im Oracle Universum zugleich: Silvia Kaske, Senior Director Channel A&C eröffnete den Partner Day, danach stellte David Callaghan (Senior Vice President UK, Ireland, Israel) die EMEA-Strategien für das FY13 vor und Jürgen Kunz (SVP Technology Northern Europe & Country Leader Germany) sprach über die Geschäftsmöglichkeiten mit Partnern. Christian Werner gab in seiner neuen Funktion als Senior Director Alliances & Channels Germany einen Überblick über die neue Struktur des Oracle Channels und stellte das deutsche Team vor. Zum Abschluss folgte mit Prof. Hermann Maurer ein Gastredner von der Academia Europaea, einer prominent besetzten akademischen Gesellschaft, die sich dem besseren Verständnis der Wissenschaft in der Öffentlichkeit verschrieben hat. Er wagte einen Blick in die Zukunft der IT: „Das Beste kommt erst noch“. Wie immer, in einem so komprimierten Programm, bleibt noch die eine oder andere Frage – aber jetzt ist ja Zeit, bei Coffee & Networking noch mal nachzufragen. Kurz nach 14 Uhr Viele haben inzwischen auch das erste Obergeschoss erkundet. In der Partner Service Zone ist das Angebot breit gefächert: Von Oracle Financing über das License Management bis hin zu OPN Specialized dreht sich hier alles um konkrete Angebote für Partner. Nach einem kurzen Abstecher in die ISV-Lounge, geht es weiter zur Expert Zone: Oracle Database, Oracle Options, Fusion Middleware, Applications und Oracle Hardware heißen hier die Themen und an den Infoständen wird bereits lautstark gefachsimpelt. Zurück im Erdgeschoss sieht man noch diverse Partner, Oracle Executives und andere Teilnehmer durcheinander wuseln, um ihre Breakout Session zu finden. Andere blättern im druckfrischen A&C Kursbuch. In den nächsten zwei Stunden stehen Business Opportunities im Fokus – aufgeteilt nach Hardware, Technology oder Sales Partnern – dazu noch die Angebote der VADs, die A&C Partner Sessions und das 1:1 Speed Dating. Einige Partner nutzen parallel die angebotenen Implementation Tests, um direkt vor Ort die Zertifizierung zu erhalten. Das doppelte Angebot der Breakouts ermöglicht den Teilnehmern, an möglichst vielen Sessions nacheinander teilzunehmen. Kein Thema soll zu kurz kommen! Ein AusblickWas erwartet uns noch, im Laufe des Nachmittags? Sehr informativ wird sicherlich das Leader Panel, in dem die teilnehmenden Partner Fragen an Oracle Executives stellen können. Wenn dann die ersten Teilnehmer unruhig werden, hat das nichts mit den Themen zu tun. Nein, es steht vielmehr noch ein spannender Höhepunkt bevor: die Partner Award Ceremony (über die wir später ausführlich berichten werden). Nach einer hoffentlich gelungenen Veranstaltung stellt sich zum Schluss nur noch die Frage, was sich genau hinter der „Red Stack Arena Sports Challenge“ verbirgt. Brauchen wir Turnschuhe?

  • Implementing Search for BlogReader Windows 8 Sample

    - by Harish Ranganathan
    The BlogReader sample is an excellent place to start speeding up your Windows 8 development skills.  The tutorial is available here and the complete source code is available here Create a project called WindowsBlogReader and create pages for ItemsPage.xaml, SplitPage.xaml and DetailPage.xaml and copy the corresponding code blocks from the sample listed above. Created a class file FeedData.cs and copy the code.  Finally, create a class DateConverter.cs and copy the code associated with it. With that you should be able to build and run the project.  There seems to be one issue in the sample feeds listed that the first week (feed1) doesn’t seem to expose it.  So you can skip that and use the second feed as first feed.  You will end up with one feed less but it works. I had demonstrated this in the recent TechDays at Chennai.  How we can use the Search Contract and implement Search for within the Blog Titles. First off, we need to declare that the App will be using Search Contract, in the Package.appmanifest file Next, we would need a handle of the Search Contract when user types on the search window in Charms Menu. If you had completed the code sample from the link above, you would have ItemsPage.xaml and ItemsPage.xaml.cs.  Open the ItemsPage.xaml.cs. Import the namespaces using System.Collections.ObjectModel and System.Linq. in the ItemsPage() constructor, right after this.InitializeComponent(); add the following code Windows.ApplicationModel.Search.SearchPane.GetForCurrentView().QuerySubmitted += ItemsPage_QuerySubmitted; This event is fired when users open up the Search Panel from Charms Menu, type something and hit enter. We need to handle this event declared in the delegate.  For that we need to pull the FeedDataSource instantiation to the root of the class to make it global. So, add the following as the first line within the partial class FeedDataSource feedDataSource; Also, modify the LoadState method, as follows:- protected override void LoadState(Object navigationParameter, Dictionary<String, Object> pageState)        {            feedDataSource = (FeedDataSource)App.Current.Resources["feedDataSource"];            if (feedDataSource != null)            {                this.DefaultViewModel["Items"] = feedDataSource.Feeds;            }        } Next is to implement the ItemsPage_QuerySubmitted method void ItemsPage_QuerySubmitted(Windows.ApplicationModel.Search.SearchPane sender, Windows.ApplicationModel.Search.SearchPaneQuerySubmittedEventArgs args)         {             this.DefaultViewModel["Items"] = from dynamic item in feedDataSource.Feeds                                              where                                              item.Title.Contains(args.QueryText)                                              select item;         } As you can see we are almost using the same defaultviewmodel with the change that we are using a linq query to do a search on feeds which has the Title that matches QueryText. With this we are ready to run the app. Run the App.  Hit the Charms Menu with Windows + C key combination and type a text to search within the blog. You can see that it filters the Blogs which has the matching text. We can modify the above Linq query to do a search for the Text in other attributes like description, actual blog content etc., I have uploaded the complete code since the original WindowsBlogReader Code is not available for download.  You can download it from here note:  this code is provided as-is without any warranties.  Cheers!!!

  • Attachments in Oracle BPM 11g – Create a BPM Process Instance by passing an Attachment

    - by Venugopal Mangipudi
    Problem Statement: On a recent engagement I had  a requirement where we needed to create BPM instances using a message start event. The challenge was that the instance needed to be created after polling a file location and attaching the picked up file (pdf) as an attachment to the instance. Proposed Solution: I was contemplating using process API to accomplish this,but came up with a solution which involves a BPEL process to pickup the file and send a notification to the BPM process by passing the attachment as a payload. The following are some of the brief steps that were used to build the solution: BPM Process to receive an attachment as part of the payload: The BPM Process is a very simple process which has a Message Start event that accepts the attachment as an argument and a Simple User Task that the user can use to view the attachment (as part of the OOTB attachment panel). The Input payload is based on AttachmentPayload.xsd.  The 3 key elements of the the payload are: <xsd:element name="filename" type="xsd:string"/> <xsd:element name="mimetype" type="xsd:string"/> <xsd:element name="content" type="xsd:base64Binary"/> A screenshot of the Human task data assignment that need to performed to attach the file is provided here. Once the process and the UI project (default generated UI) are deployed to the SOA server, copy the wsdl location of the process service (from EM). This WSDL would be used in the BPEL project to create the Instances in the BPM process after a file is polled. BPEL Process to Poll for File and create instances in the BPM process: For the BPEL process a File adapter was configured as a Read service (File Streaming option and keeping the Schema as Opaque). Once a location and the file pattern to poll are provided the Readservice Partner Link was wired to Invoke the BPEL Process. Also, using the BPM Process WSDL, we can create the Webservice reference and can invoke the start operation. Before we do the assignment for the Invoke operation, a global variable should be created to hold the value of the fileName of the file. The mapping to the global variable can be done on the Receive activity properties (jca.file.FileName).  So for the assign operation before we invoke the BPM process service, we can get the content of the file from the receive input variable and the fileName from the jca.file.FileName property. The mimetype needs to be hard coded to the mime-type of the file: application/pdf (I am still researching ways to derive the mime type as it is not available as part of the jca.file properties).  The screenshot of the BPEL process can be found here and the Assign activity can be found here. The project source can be found at the following location. A sample pdf file to test the project and a screenshot of the BPM Human task screen after the successful creation of the instance can be found here.

In past posts we have discussed session themes and our customer panel, but today I would like to summarize our Hands-on Labs and Demo Pods that we have available for attendees. For Oracle GoldenGate Hands-On Labs we have two labs that we are running this year. Deep Dive into Oracle GoldenGate Thursday October 4th at 11:15AM in the Marriott Marquis Salon 1/2 Oracle GoldenGate provides real-time log-based change data capture and delivery between heterogeneous systems. It enables cost-effective, low-impact, real-time data integration and continuous availability solutions. This session covers Oracle GoldenGate 11g’s internal product architecture and includes a hands-on lab that covers configuration examples for target database instantiation and real-time change data capture and delivery. The participants will configure Oracle GoldenGate to instantiate a secondary database that can be used for disaster recovery or a reporting instance. Come learn how easy it is to use and how this can be a very valuable and easy technology solution for your organization. Introduction to Oracle GoldenGate Veridata Wednesday October 3rd 10:15AM in the Marriott Marquis Sales 1/2 Oracle GoldenGate Veridata compares one set of data with another and identifies data that is out of synchronization. In this hands-on lab, you will be introduced to the key features of this product. Using the Oracle GoldenGate Veridata Web client, you will have the opportunity to configure comparison objects and rules, initiate a comparison, review the status and output of a comparison, and review out-of-sync data. As a bonus this year, we have recorded the labs and made them available on youtube.com/oraclegoldengate. These will be available the day of the labs. Our demo pods are an opportunity for attendees to see our products but more so to meet the product management and development teams. I would like to point out that we have two Oracle GoldenGate 11gR2 demo pods, one in the database camp and the other in the middleware camp. The one in the middleware camp will be focused on all platforms while the one in the database camp will have a focus on the Oracle platform. The other two I would like to point out are the Monitoring Oracle GoldenGate and the Oracle Enterprise Manager demo pods; both of these pods will focus on methods to monitor GoldenGate but the OEM demo pod will have a specific focus on the Oracle GoldenGate Management Pack plug-in for OEM. Below is a list of our demo pods and their locations.

  • Live Event: OTN Architect Day: Cloud Computing - Two weeks and counting

    - by Bob Rhubart
    In just two weeks architects and others will gather at the Oracle Conference Center in Redwood Shores, CA for the first Oracle Technology Network Architect Day event of 2013. This event focuses on Cloud Computing, and features sessions specifically focused on real-world examples of the implementation of cloud computing. When: Tuesday July 9, 2013              8:30am - 12:30pm Where: Oracle Conference Center              350 Oracle Pkwy              Redwood City, CA 94065 Register now. It's free! Here's the agenda: 8:30am - 9:00am Registration and Continental Breakfast 9:00am - 9:45am Keynote 21st Century IT | Dr. James Baty VP, Global Enterprise Architecture Program, Oracle Imagine a time long, long ago. A time when servers were certified and dedicated to specific applications, when anything posted on an enterprise web site was from restricted, approved channels, and when we tried to limit the growth of 'dirty' data and storage. Today, applications are services running in the muti-tenant hybrid cloud. Companies beg their customers to tweet them, friend them, and publicly rate their products. And constantly analyzing a deluge of Internet, social and sensor data is the key to creating the next super-successful product, or capturing an evil terrorist. The old IT architecture was planned, dedicated, stable, controlled, with separate and well-defined roles. The new architecture is shared, dynamic, continuous, XaaS, DevOps. This keynote session describes the challenges and opportunities that the new business / IT paradigms present to the IT architecture and architects. 9:45am - 10:30am Technical Session Oracle Cloud: A Case Study in Building a Cloud | Anbu Krishnaswami Enterprise Architect, Oracle Building a Cloud can be challenging thanks to the complex requirements unique to Cloud computing and the massive scale typically associated with Cloud. Cloud providers can take an Infrastructure as a Service (IaaS) approach and build a cloud on virtualized commodity hardware, or they can take the Platform as a Service (PaaS) path, a service-oriented approach based on pre-configured, integrated, engineered systems. This presentation uses the Oracle Cloud itself as a case study in the use of engineered systems, demonstrating how the technical design of engineered systems is leveraged for building PaaS and SaaS Cloud services and a Cloud management infrastructure. The presentation will also explore the principles, patterns, best practices, and architecture views provided in Oracle's Cloud reference architecture. 10:30 am -10:45 am Break 10:45am-11:30am Technical Session Database as a Service | Michael Timpanaro-Perrotta Director, Product Management, Oracle Database Cloud New applications are now commonly built in a Cloud model, where the database is consumed as a service, and many established business processes are beginning to migrate to database as a service (DBaaS). This adoption of DBaaS is made possible by the availability of new capabilities in the database that enable resource pooling, dynamic resource management, model-based provisioning, metered use, and effective quality-of-service controls. This session will examine the catalog of database services at a large commercial bank to understand how these capabilities are enabling DBaaS for a wide range of needs within the enterprise. 11:30 am - 12:00 pm Panel Q&A Dr. James Baty, Anbu Krishnaswami, and Michael Timpanaro-Perrotta respond to audience questions. Registration is free, but seating is limited, so register now.

This presentation uses the Oracle Cloud itself as a case study in the use of engineered systems, demonstrating how the technical design of engineered systems is leveraged for building PaaS and SaaS Cloud services and a Cloud management infrastructure. The presentation will also explore the principles, patterns, best practices, and architecture views provided in Oracle's Cloud reference architecture. 10:30 am -10:45 am Break 10:45am-11:30am Technical Session Database as a Service | Michael Timpanaro-Perrotta Director, Product Management, Oracle Database Cloud New applications are now commonly built in a Cloud model, where the database is consumed as a service, and many established business processes are beginning to migrate to database as a service (DBaaS). This adoption of DBaaS is made possible by the availability of new capabilities in the database that enable resource pooling, dynamic resource management, model-based provisioning, metered use, and effective quality-of-service controls. This session will examine the catalog of database services at a large commercial bank to understand how these capabilities are enabling DBaaS for a wide range of needs within the enterprise. 11:30 am - 12:00 pm Panel Q&A Dr. James Baty, Anbu Krishnaswami, and Michael Timpanaro-Perrotta respond to audience questions. Registration is free, but seating is limited, so register now.

  • Oracle OpenWorld 2012: Oracle Developer Cloud, ADF-Essentials, ADF Mobile and ME!

    - by Dana Singleterry
    This year at OOW, like those from the past, will certainly be unforgettable. Lots of new announcements which I can't mention here and may not event know about are sure to surprise. I'll keep this short and sweet. For every session ADF, ADF Mobile, Oracle Developer Cloud, Integration with SOA Suite, etc... take a look at the ADF Focus Document listing all the sessions ordered by day providing time and location. For Mobile specifically check out the Mobile Focus Document. OOW 2012 actually kicks off on Sunday with Moscone North demogrounds hosting Cloud. There's also the ADF EMG User Day where you can pick up many technical tips & tricks from ADF Developers / ACE Directors from around the world. A session you shouldn't miss and a great starting point for the week if you miss Sunday's ADF EMG User Day for all of you TechoFiles is Chris Tonas's keynote for developers - Monday 10:45 am at Salon 8 in the Marriott - The Future of Development for Oracle Fusion - From Desktop to Mobile to Cloud. Then peruse the ADF Focus Document to fill out your day with the many sessions and labs on ADF. Don't forge that Wednesday afternoon (4:30 - 5:30) offers an ADF Meetup which is an excellent opportunity to catch up with the Shakers and Makers of ADF from Product Managent, to customers, to top developers leveraging the ADF technology, to ACE Directors themselves. Not to mention free beer is provided to help you wind down from a day of Techno Overload. Now for my schedule and I do hope to see some of you at one of these. OOW 2012 Schedule 10/1 Monday 9:30am – 12:00pm: JDev DemoGrounds 3:15pm – 4:15pm: Intro to Oracle ADF HOL; Marriott Marquis – Salon ¾ 4:00pm – 6:00pm: Cloud DemoGrounds 10/2 Tuesday 9:45am – 12:00pm: JDev DemoGrounds 2:00pm -4:00pm: Cloud DemoGrounds 7:30 – 9:30: Team Dinner @ Donato Enoteca; Redwood City 10/3 Wednesday 10:15pm – 11:15pm: Intro to Oracle ADF HOL; Marriott Marquis – Salon 3/4 1:15pm – 2:15pm: Oracle ADF – Lessons Learned in Real-World Implementations; Moscone South – Room 309This session takes the form of a panel that consists of three customer: Herbalife, Etiya, & Hawaii State Department of Education. During the first part of this session each customer will provide a high-level overview of their application. Following this overview I'll ask questions of the customers specific to their implementations and lessons learned through their development life-cycle. Here's the session abstract: CON3535 - Oracle ADF: Lessons Learned in Real-World Implementations This session profiles and interviews customers that have been successful in delivering compelling applications based on Oracle’s Application Development Framework (Oracle ADF). The session provides an overview of Oracle ADF, and then three customers explain the business drivers for their respective applications and solutions and if possible, provide a demonstration of the applications. Interactive questions posed to the customers after their overview will make for an exciting and dynamic format in which the customers will provide insight into real-world lessons learned in developing with Oracle ADF. 3:30pm – 4:30 pm: Developing Applications for Mobile iOS and Android Devices with Oracle ADF Mobile; Marriott Marquis – Salon 10A 4:30pm – 6:00pm: Meet and Greet ADF Developers/Customers; OTN Lounge 10/4 Thursday   11:15pm – 12:15pm: Intro to Oracle ADF HOL; Marriott Marquis – Salon 3/4 I'm sure our paths will cross at some point during the week and I look forward to seeing you at one of the many events. Enjoy OOW 2012!

  • Sharing configuration settings between Windows Azure roles

    - by theo.spears
    If you are working on a medium-large Windows Azure project it's likely it will involve more than one role, for example separate web and worker roles. Unfortunately although all the windows azure configuration settings are stored in a single cscfg file, there is no way to share configuration settings between multiple roles. This means you have to duplicate common settings like connection strings across all your roles. There is an open Connect issue about this topic, but Microsoft have not said when they will fix it. In the mean time I've put together a dirty dirty hack cunning workaround that creates a fake role containing your shared configuration settings, and copies it to all roles as part of the build process. Here's how you set it up: 1. Download the zip file attached to this post, and unzip it into the folder containing your Azure project (not your solution folder). 2. Edit your csdef and cscfg files to include the placeholder project ServiceDefinition.csdef<?xml version="1.0" encoding="utf-8"?> <ServiceDefinition name="AzureSpendNotifier" http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceDefinition%22"http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceDefinition"> <WorkerRole name="GLOBAL"> <ConfigurationSettings> <Setting name="ExampleSetting" /> </ConfigurationSettings> </WorkerRole> <WorkerRole name="MyWorker"> <ConfigurationSettings> </ConfigurationSettings> </WorkerRole> <WebRole name="MyWeb"> <Sites> <Site name="Web"> <Bindings> <Binding name="WebEndpoint" endpointName="WebEndpoint" /> </Bindings> </Site> </Sites> <ConfigurationSettings> </ConfigurationSettings> </WebRole> </ServiceDefinition> ServiceConfiguration.cscfg<?xml version="1.0" encoding="utf-8"?> <ServiceConfiguration serviceName="AzureSpendNotifier" xmlns=http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceConfiguration osFamily="1" osVersion="*"> <Role name="GLOBAL"> <ConfigurationSettings> <Setting name="ExampleSetting" value="Hello World" /> </ConfigurationSettings> <Instances count="1" /> </Role> <Role name="MyWorker"> <Instances count="1" /> <ConfigurationSettings> </ConfigurationSettings> </Role> <Role name="MyWeb"> <Instances count="1" /> <ConfigurationSettings> </ConfigurationSettings> </Role> </ServiceConfiguration> It is important that all your roles contain a ConfigurationSettings entry in both cscfg and csdef files, even if it's empty- otherwise the shared configuration settings will not be inserted. 3. Open your azure deployment (.ccproj) project in notepad, and add the highlighted line below: ... <Import Project="$(CloudExtensionsDir)Microsoft.CloudService.targets" /> <Import Project="globalsettings/globalsettings.targets" /> </Project> It is important you add this below the Microsoft.CloudService.targets import line, as it replaces some of the rules defined in that file. Visual studio will prompt you to reload the project, say yes. At this point you will have a new Azure role called 'GLOBAL' with settings you can edit through the visual studio properties panel as normal. This role will never be deployed, but any settings you add to it will be copied to all your other roles when deployed or tested locally within visual studio.

  • Talking JavaOne with Rock Star Kirk Pepperdine

    - by Janice J. Heiss
    Kirk Pepperdine is not only a JavaOne Rock Star but a Java Champion and a highly regarded expert in Java performance tuning who works as a consultant, educator, and author. He is the principal consultant at Kodewerk Ltd. He speaks frequently at conferences and co-authored the Ant Developer's Handbook. In the rapidly shifting world of information technology, Pepperdine, as much as anyone, keeps up with what's happening with Java performance tuning. Pepperdine will participate in the following sessions: CON5405 - Are Your Garbage Collection Logs Speaking to You? BOF6540 - Java Champions and JUG Leaders Meet Oracle Executives (with Jeff Genender, Mattias Karlsson, Henrik Stahl, Georges Saab) HOL6500 - Finding and Solving Java Deadlocks (with Heinz Kabutz, Ellen Kraffmiller Martijn Verburg, Jeff Genender, and Henri Tremblay) I asked him what technological changes need to be taken into account in performance tuning. “The volume of data we're dealing with just seems to be getting bigger and bigger all the time,” observed Pepperdine. “A couple of years ago you'd never think of needing a heap that was 64g, but today there are deployments where the heap has grown to 256g and tomorrow there are plans for heaps that are even larger. Dealing with all that data simply requires more horse power and some very specialized techniques. In some cases, teams are trying to push hardware to the breaking point. Under those conditions, you need to be very clever just to get things to work -- let alone to get them to be fast. We are very quickly moving from a world where everything happens in a transaction to one where if you were to even consider using a transaction, you've lost." When asked about the greatest misconceptions about performance tuning that he currently encounters, he said, “If you have a performance problem, you should start looking at code at the very least and for that extra step, whip out an execution profiler. I'm not going to say that I never use execution profilers or look at code. What I will say is that execution profilers are effective for a small subset of performance problems and code is literally the last thing you should look at.And what is the most exciting thing happening in the world of Java today? “Interesting question because so many people would say that nothing exciting is happening in Java. Some might be disappointed that a few features have slipped in terms of scheduling. But I'd disagree with the first group and I'm not so concerned about the slippage because I still see a lot of exciting things happening. First, lambda will finally be with us and with lambda will come better ways.” For JavaOne, he is proctoring for Heinz Kabutz's lab. “I'm actually looking forward to that more than I am to my own talk,” he remarked. “Heinz will be the third non-Sun/Oracle employee to present a lab and the first since Oracle began hosting JavaOne. He's got a great message. He's spent a ton of time making sure things are going to work, and we've got a great team of proctors to help out. After that, getting my talk done, the Java Champion's panel session and then kicking back and just meeting up and talking to some Java heads."Finally, what should Java developers know that they currently do not know? “’Write Once, Run Everywhere’ is a great slogan and Java has come closer to that dream than any other technology stack that I've used. That said, different hardware bits work differently and as hard as we try, the JVM can't hide all the differences. Plus, if we are to get good performance we need to work with our hardware and not against it. All this implies that Java developers need to know more about the hardware they are deploying to.” Originally published on blogs.oracle.com/javaone.

  • Unmet Dependencies with kdelibs5-data

    - by Jitesh
    I was trying to install Amarok 1.4 on Ubuntu 12.04 (Gnome-classic), by following this instructions. Problem started after giving these two commands dpkg -i kdelibs5-data_4.6.2-0ubuntu4_all.deb dpkg -i kdelibs-data_3.5.10.dfsg.1-5ubuntu2_all.deb Now, immediately after these commands, Ubuntu Updater popped up and gave me an error that the package catalog is broken and needs to be repaired. Nothing can be installed or removed till then. It also offered a suggestion to run apt-get install -f. I tried that, but again got the same error.Also tried apt-get clean followed by apt-get install -f.

Now when I tried to install Amarok 1.4, I'm getting these errors. I also have digiKam and k3b installed, if that can be of any help. I use digiKam a lot, so removing KDE is not feasible for me. Any help on this issue will be highly appreciated. Thanks in advance.

  • OpenGL (glx) not working with ubuntu 12.10

    - by user26766
    It all started when I installed nvidia's own (download from website) driver. Uninstalling it and reverting back to nvidia-current didn't solve the problem, so I have been playing with this for a while. It seems glx support is missing, and my intel graphics is not responding. gnome loads only in fallback mode. Here are some outputs: glxinfo name of display: :0.0 Error: couldn't find RGB GLX visual or fbconfig glxgears Error: couldn't get an RGB, Double-buffered visual optirun glxgears works fine lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation GF108 [GeForce GT 540M] (rev ff) Here's the content of log file when just after running glxinfo: less /var/log/Xorg.0.log | grep gl [ 112.156] (II) LoadModule: "glx" [ 112.157] (II) Loading /usr/lib/xorg/modules/extensions/libglx.so [ 112.157] (II) Module glx: vendor="X.Org Foundation" [ 112.157] (II) UnloadModule: "glx" [ 112.157] (II) Unloading glx [ 112.157] (EE) Failed to load module "glx" (module requirement mismatch, 0) Some more info... lsmod Module Size Used by bbswitch 13612 0 pci_stub 12623 1 vboxpci 23195 0 vboxnetadp 25671 0 vboxnetflt 23480 0 vboxdrv 320372 3 vboxpci,vboxnetadp,vboxnetflt parport_pc 32689 0 ppdev 17074 0 bnep 18141 2 rfcomm 46620 12 binfmt_misc 17501 1 snd_hda_codec_hdmi 32049 1 snd_hda_codec_realtek 78147 1 joydev 17458 0 uvcvideo 76750 0 videobuf2_core 32852 1 uvcvideo videodev 120310 2 uvcvideo,videobuf2_core videobuf2_vmalloc 12861 1 uvcvideo videobuf2_memops 13405 1 videobuf2_vmalloc snd_hda_intel 33492 3 coretemp 13401 0 kvm_intel 132760 0 arc4 12530 2 snd_hda_codec 134213 3 snd_hda_codec_hdmi,snd_hda_codec_realtek,snd_hda_intel kvm 414111 1 kvm_intel iwlwifi 386837 0 i915 520799 2 snd_hwdep 17699 1 snd_hda_codec snd_pcm 96668 3 snd_hda_codec_hdmi,snd_hda_intel,snd_hda_codec psmouse 100389 0 drm_kms_helper 49113 1 i915 ghash_clmulni_intel 13221 0 snd_seq_midi 13325 0 snd_rawmidi 30513 1 snd_seq_midi btusb 22475 0 drm 288436 3 i915,drm_kms_helper serio_raw 13216 0 snd_seq_midi_event 14900 1 snd_seq_midi snd_seq 61555 2 snd_seq_midi,snd_seq_midi_event mac80211 535936 1 iwlwifi bluetooth 209249 22 bnep,rfcomm,btusb snd_timer 29426 2 snd_pcm,snd_seq snd_seq_device 14498 3 snd_seq_midi,snd_rawmidi,snd_seq snd 78921 16 snd_hda_codec_hdmi,snd_hda_codec_realtek,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm,snd_rawmidi,snd_seq,snd_timer,snd_seq_device cfg80211 206797 2 iwlwifi,mac80211 aesni_intel 51038 1 cryptd 20404 2 ghash_clmulni_intel,aesni_intel aes_x86_64 17256 1 aesni_intel dell_wmi 12682 0 sparse_keymap 13891 1 dell_wmi dcdbas 14439 0 i2c_algo_bit 13414 1 i915 microcode 22804 0 lpc_ich 17062 0 soundcore 15048 1 snd snd_page_alloc 18485 2 snd_hda_intel,snd_pcm video 19391 1 i915 mac_hid 13206 0 wmi 19071 1 dell_wmi mei 40691 0 lp 17760 0 parport 46346 3 parport_pc,ppdev,lp ahci 25721 3 libahci 31192 1 ahci atl1c 41102 0 how can I fix this? any ideas?

However I didn't find any obvious link to /lib/nvidia-current in /etc/ld.so.conf (where the directories containing the shared libraries are listed). I don't know if there's anything missing or if this is normal. thanks, UPDATE: The problem was solved by updating to Ubuntu 13.04. It seems bumblebee was to blame, but I'm not sure what was going wrong...

  • Why I Love the Social Management Platform I Use

    - by Mike Stiles
    Not long ago, I asked the product heads for the various components of the Oracle Social Cloud’s SRM to say what they thought was coolest about their component. And while they did a fine job, it was recently pointed out to me that no one around here uses the platform in a real-world setting more than I do, as I not only blog and podcast my brains out, I also run Oracle Social’s own social properties. Of course I’m pro-Oracle Social’s product. Duh. But if you can get around immediately writing this off as a puff piece, there are real reasons beyond my employment that the Oracle SRM works for me as a community manager. If it didn’t, I could have simply written about something else, like how people love smartphones or something genius like that. Post Grid I like seeing what I want to see. I’m difficult that way. Post grid lets me see all posts for all channels, with custom columns showing me how posts are doing. I can filter the grid by social channel, published, scheduled, draft, suggested, etc. Then there’s a pullout side panel that shows me post details, including engagement analytics. From the pullout, I can preview the post, do a quick edit, a full edit, or (my favorite) copy a post so I can edit it and schedule it for other times so I don’t have to repeat from scratch. I’m not lazy, just time conscious. The Post Creation Environment Given our post volume, I need this to be as easy as it can be. I can highlight which streams I want the post to go out on, edit for the individual streams, maintain a media library that’s easy to upload to and attach from, tag posts, insert links that auto-shorten to an orac.le shortlink, schedule with a nice calendar visual, geo-target, drop photos inline into Twitter, and review each post. Watching My Channels The Engage component of the Oracle SRM brings in and drops into a grid the activity that’s happening on all my channels. I keep this open round-the-clock. Again, I get to see only what I want; social network, stream, unread messages, engagement by how I labeled them, and date range. I can bring up a post with a click, reply, label it, retweet it, assign it, delete it, archive it, etc. So don’t bother trying to be a troll on my channels. Analytics Social publishing and engaging 24/7 would be pretty unrewarding if I couldn’t see how our audience was responding. Frankly, I get more analytics than I know what to do with (I’m a content creator, not a data analyst). But I do know what numbers I care about, and they’re available by channel, date range, and campaigns. I’m seeing fan count, sources and demographics. I’m seeing engagement, what kinds of posts are getting engagement, and top engagers. I’m seeing my reach, both organic and paid. I’m seeing how individual posts performed in terms of engagement and virality, and posting time/date insight. Have I covered all the value propositions? I’ve covered pathetically few of them. It would be impossible in blog length to give shout-outs to the vast number of features and functionalities. From organizing teams and managing permissions with Workflow to the powerful ability to monitor topics (and your competition) across the web in Listen, it’s a major, and increasingly necessary, weapon in your social marketing arsenal. The life of a Community Manager is not for everybody. So if the Oracle SRM can actually make a Community Manager’s life easier, what’s not to love? I invite you to take a look at and participate in our Oracle Social Cloud social channels!

  • Setting up a Carousel Component in ADF Mobile

    - by Shay Shmeltzer
    The Carousel component is one of the slickier ways of showing collections of data, and on a mobile device it works really great with the finger swipe gesture. Using the Carousel component in ADF Mobile is similar to using it in regular web ADF applications, with one major change - right now you can't drag a collection from the data control palette and drop it as a carousel. So here is a quick work around for that, and details about setting up carousels in your application. First thing you'll need is a data control that returns an array of records. In my demo I'm using the Emps collection that you can get from following this tutorial. Then you drag the emps and drop it in your amx page as an ADF mobile iterator. We are doing this as a short cut to getting the right binding needed for a carousel in our page. If you look now in your page's binding you'll see something like this: You can now remark the whole iterator code in your page's source. Next let's add the carousel From the component palette drag the carousel (from the data view category) to the page. Next drag a carousel item and drop it in the nodestamp facet of the carousel. Now we'll hook up the carousel to the binding we got from the iterator - this is quite simple just copy the var and value attributes from the iterator tag to the carousel tag: var="row" value="#{bindings.emps.collectionModel}" Next drop a panelForm, or another layout panel in to the carousel item. Into that panelForm you can now drop items and bind their value property to row.attributeNames - basically copying the way it is in the fields in the iterator for example: value="#{row.hireDate}". By the way you can also copy other attributes like the label. And that's it. Your code should end up looking something like this:     <amx:carousel id="c1" var="row" value="#{bindings.emps.collectionModel}">      <amx:facet name="nodeStamp">        <amx:carouselItem id="ci1">          <amx:panelFormLayout id="pfl1">            <amx:inputText label="#{bindings.emps.hints.salary.label}" value="#{row.salary}" id="it1"/>            <amx:inputText label="#{bindings.emps.hints.name.label}" value="#{row.name}" id="it2"/>          </amx:panelFormLayout>        </amx:carouselItem>      </amx:facet>    </amx:carousel> And when you run your application it will look like this:

  • Fixing some Visual Studio RC install issues

    - by terje
    The Visual Studio RC has shown some install issues in some cases, particularly for those who upgrades from VS 11 Beta.  I have listed the fixes known now below, and will update if there are more issues.  Note that a repair will not fix the issue, and a Windows restore and subsequent reinstall may not fix it either.  The system seems to remember too much. That was the case for me, at least.  The fixes below however, cures these issues. 1. The Team Explorer Build node doesn’t work You get an error saying System.TypeLoadException like this: To solve this do as follows: 1. Open a command prompt as administrator 2. Go to your program files directory for VS 2012 and down to  the extension folder like:   C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer 3. Run “gacutil –if Microsoft.TeamFoundation.Build.Controls.dll     2. The SQL Editor gives loading error When you start up VS 2012 RC you get a loading error message.  The same happens if you try to go from the menu to  SQL/Transact-SQL Editor/New Query.    To solve this do as follows: 1. Open Control Panel/Programs and Features 2. Locate the “Microsoft SQL Server 2012 Data-Tier App Framework     (Note , you might find up to 4 such instances) The ones with version numbers ending in 55 is from the SQL 2012 RC, the ones ending in 60 is from the SQL 2012 RTM.  There are two of each, one for x32 and one for x64.  Which is which no one knows. 3. Right click each of them, and select Repair. (It would be nice if someone with this issue tries only the latest RTM ones, and see if that clears the error, and comment back to this post. I am out of non-functioning VS’s )   3.  Errors referring to some extension You get errors referring to some extension that can’t be loaded, or can’t be found.  Check the activity log (see below), and verify there.  If you see yellow collision warnings there, the fix here should solve those too. To solve these:    1. Open a Visual Studio 2012 command prompt 2.  Run:   devenv /resetsettings     How to check for errors using the log Do as follows to get to the activity log for Visual studio 2012 RC 1. Open a Visual Studio 2012 command prompt 2. Run:   devenv /log This starts up Visual Studio.  3. Go to %appdata%/Microsoft\VisualStudio\11.0 4. Double click the file named ActivityLog.xml.  It will start up in your browser, and be formatted using the xslt in the same directory. 5.  Look for items marked in red.  Example for Issue 1 :

  • At the Java DEMOgrounds - Oracle Java ME Embedded Enables the “Internet of Things”

    - by Janice J. Heiss
    I caught up with Oracle’s Robert Barnes, Senior Director, Java Product Management, who was demonstrating a new product from Oracle’s Java Platform, Micro Edition (Java ME) product portfolio, Oracle Java ME Embedded 3.2, a complete client Java runtime optimized for microcontrollers and other resource-constrained devices. Oracle’s Java ME Embedded 3.2 is a Java ME runtime based on CLDC 1.1 (JSR-139) and IMP-NG (JSR-228).“What we are showing here is the Java ME Embedded 3.2 that we announced last week,” explained Barnes. “It’s the start of the 'Internet of Things,’ in which you have very very small devices that are on the edge of the network where the sensors sit. You often have a middle area called a gateway or a concentrator which is fairly middle to higher performance. On the back end you have a very high performance server. What this is showing is Java spanning all the way from the server side right down towards the type of chip that you will get at the sensor side as the network.” Barnes explained that he had two different demos running.The first, called the Solar Panel System Demo, measures the brightness of the light.  “This,” said Barnes, “is a light source demo with a Cortex M3 controlling the motor, on the end of which is a sensor which is measuring the brightness of the lamp. This is recording the data of the brightness of the lamp and as we move the lamp out of the way, we should be able using the server to turn the sensor towards the lamp so the brightness reading will go higher. This sends the message back to the server and we can look at the web server sitting on the PC underneath the desk. We can actually see the data being passed back effectively through a back office type of function within a utility environment.” The second demo, the Smart Grid Response Demo, Barnes explained, “has the same board and processor and is still using Java ME embedded with a different app on top. This is a demand response demo. What we are seeing within the managing environment is that people want to track the pricing signals of the electricity. If it’s particularly expensive at any point in time, they may turn something off. This demo sets the price of the electricity as though this is coming from the back of the server sending pricing signals to my home.” The demo had a lamp and a fan and it was tracking the price of electricity. “If I set the price of the electricity to go over 5 cents, then the device will turn off,” explained Barnes. “I can go into my settings and, in this case, change the price to 50 cents and we can wait a minus and the lamp will go off. When I change the pricing signal so that it is lower, the lamp will come back on. The key point is that the Java software we have running is the same across all the different devices; it’s a way to build applications across multiple devices using the same software. This is important because it fixes peak loading on the network and can stops blackouts.” This demo brought me back to a prior decade when Sun Microsystems first promoted  Jini technology, a version of Java that would put everything on the network and give us the smart home. Your home would be automated to tell you when you were out of milk, when to change your light bulbs, etc. You would have access to the web and the network throughout your home.It’s interesting to see how technology moves over time – from the smart home to the Internet of Things.

  • Three Buckets of Knowledge

    - by BuckWoody
    As I learn more and more about SQL Server every day, I divide up my information into three “buckets”: Concepts In the first bucket are the general concepts about the topic. What is it? What does it do (or sometimes, what is is supposed to do?) How does one operation flow to another? For this information I use books, magazine articles and believe it or not – Wikipedia. I don’t always trust that last source, but I do use it to see how others lay out their thoughts around a concept. I really like graphical charts that show me the process flow if I can get it, and this is an ideal place for a good presentation. In fact, this may be the only real use for a presentation – I’ll explain what I mean in a moment. Reference The references for a topic include things like Transact-SQL (T-SQL) syntax, or the screen layout on a panel, things like that. Think Dictionary. The only reference I trust for this information is Books Online – presentations are fine, but we’re talking about a dictionary. Ever go to a movie that just reads through a dictionary? Me neither. But I have gone to presentations where people try to include tons of reference materials in their slides. Even if you give me the presentation material later, it’s not really a searchable, readable medium. How To A how-to for me is an example, or even better, a tutorial about an example. Whatever it is shows me a practical use for the concepts and of course involves the syntax. The important thing here is that you need to be able to separate out the example the person is showing you from the stuff you need to know. I can’t tell you how many times folks have told me, “well, sure, if yours is red then that works. But mine is blue.” And I have to explain, “then use “blue” for the search word here.” You get the idea. No one will do your work for you – the examples are meant as a teaching tool only. I accept that, learn what I can, and then run off to create my own thing. You might think a How To works well in a presentation, and it does, for the most part. For a complex example or tutorial, I still prefer the printed word (electronic if possible) so that I can go over the example multiple times, skip around and so on.   The order here isn’t actually that important. Most of the time I start with a concept, look at an example, and then read the reference material. But sometimes I look up an example, read a little of concepts and then check the reference. The only primary thing I try to enforce is to read something from each of them. It’s dangerous to base your work on any single example, reference or concept.  Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • Talking JavaOne with Rock Star Kirk Pepperdine

    - by Janice J. Heiss
    Kirk Pepperdine is not only a JavaOne Rock Star but a Java Champion and a highly regarded expert in Java performance tuning who works as a consultant, educator, and author. He is the principal consultant at Kodewerk Ltd. He speaks frequently at conferences and co-authored the Ant Developer's Handbook. In the rapidly shifting world of information technology, Pepperdine, as much as anyone, keeps up with what's happening with Java performance tuning. Pepperdine will participate in the following sessions: CON5405 - Are Your Garbage Collection Logs Speaking to You? BOF6540 - Java Champions and JUG Leaders Meet Oracle Executives (with Jeff Genender, Mattias Karlsson, Henrik Stahl, Georges Saab) HOL6500 - Finding and Solving Java Deadlocks (with Heinz Kabutz, Ellen Kraffmiller Martijn Verburg, Jeff Genender, and Henri Tremblay) I asked him what technological changes need to be taken into account in performance tuning. “The volume of data we're dealing with just seems to be getting bigger and bigger all the time,” observed Pepperdine. “A couple of years ago you'd never think of needing a heap that was 64g, but today there are deployments where the heap has grown to 256g and tomorrow there are plans for heaps that are even larger. Dealing with all that data simply requires more horse power and some very specialized techniques. In some cases, teams are trying to push hardware to the breaking point. Under those conditions, you need to be very clever just to get things to work -- let alone to get them to be fast. We are very quickly moving from a world where everything happens in a transaction to one where if you were to even consider using a transaction, you've lost." When asked about the greatest misconceptions about performance tuning that he currently encounters, he said, “If you have a performance problem, you should start looking at code at the very least and for that extra step, whip out an execution profiler. I'm not going to say that I never use execution profilers or look at code. What I will say is that execution profilers are effective for a small subset of performance problems and code is literally the last thing you should look at.And what is the most exciting thing happening in the world of Java today? “Interesting question because so many people would say that nothing exciting is happening in Java. Some might be disappointed that a few features have slipped in terms of scheduling. But I'd disagree with the first group and I'm not so concerned about the slippage because I still see a lot of exciting things happening. First, lambda will finally be with us and with lambda will come better ways.” For JavaOne, he is proctoring for Heinz Kabutz's lab. “I'm actually looking forward to that more than I am to my own talk,” he remarked. “Heinz will be the third non-Sun/Oracle employee to present a lab and the first since Oracle began hosting JavaOne. He's got a great message. He's spent a ton of time making sure things are going to work, and we've got a great team of proctors to help out. After that, getting my talk done, the Java Champion's panel session and then kicking back and just meeting up and talking to some Java heads."Finally, what should Java developers know that they currently do not know? “’Write Once, Run Everywhere’ is a great slogan and Java has come closer to that dream than any other technology stack that I've used. That said, different hardware bits work differently and as hard as we try, the JVM can't hide all the differences. Plus, if we are to get good performance we need to work with our hardware and not against it. All this implies that Java developers need to know more about the hardware they are deploying to.”
