Customizing Spaces UI

- by vijaykumar.yenne

In most common scenarios we stumble up on use cases to customize the Web center spaces UI. Is the Spaces UI customizable? What is the extent to which we can customize? How do i customize it? These are some questions that developers/architects normally come across. Well to clear the air, OOTB spaces comes with some default "site templates" and it also gives a flexibility to create custom site templates suiting the organization needs. The site templates concept has been introduced in the latest PS1 release of webcenter and to customize/create the the new site template, we have to leverage the Extend Spaces Project available on OTN. You could download the the project from here. Also there is white paper available on what all can be customized/extended from spaces perspective listed here . There is a specific details outlined on how to create custom site template in the Customizing Site Template white paper. One of the things the white paper high lights is "While you can create new site templates and modify the sample site templates but you cannot modify either of the out-of-the-box site templates ie the default and maximized. So if my need is to either increase the size of header to fit in a bigger logo or introduce couple of extra links on the default/maximized lay out how do i achieve this? All you need to do is customize the OOTB shell (shell-config.xml). 1. Copy the shell config's available in the Source Files Directory of the extended spaces unzipped directory into the CustomSite Template Project ExtendWebCenterSpaces\CustomSiteTemplate\custom\oracle\webcenter\webcenterapp\metadata\shell 2. Modify the appropriate shell 3. Deploy the CustomSite Template as ADF Jar 4. ensure you have the profile dependency on the aboproject int he custom webcenter spaces project 5. Deploy the Spaces Extension on the Webcenter Spaces Instance. (Details in the first white paper). You should see the changes immediately. eg: In the default shell, i have changed the height from 30 to 60 to increase the header size height="60" This is what i get to see : If you have worked on the R1 release time frame, where you created a custom shell/chrome, how do we make them compatible and make it available in the Spaces PS1 instance? All you need to do is the following: 1. Copy the custom shell in to the shell directory of the custom site template project 2. Register the shell with WCSiteTemplates.xml available in the same project. Eg : Yo can add the below entry pagePath="/oracle/webcenter/webcenterapp/view/templates/MyShellTemplate.jspx" pageDefPath="/oracle/webcenter/webcenterapp/bindings/pageDefs/oracle_webcenter_webcenterapp_view_templates_WebCenterAppShellTemplatePageDef.xml" displayName="myShell" chromeLevel="myShell"/ Note : pagePath - Absolute path of the template JSPX file. This path must be unique. So you might have to do the following to get your custom chrome working absolutely fine with no problems at all: 1. Create a jspx page, say /custom/mysite/SiteTemplate.jspx 2. Include the the default jspx in the new site template like following SiteTemplate.jspx ------------------ 3. Add the newly created site template in the WCSiteTemplate.xml file like following - pagePath="/custom/mysite/SiteTemplate.jspx" pageDefPath="/oracle/webcenter/webcenterapp/bindings/pageDefs/oracle_webcenter_webcenterapp_view_templates_WebCenterAppShellTemplatePageDef.xml" displayName="myShell" chromeLevel="myShell"/

Migrating SQL Server Compact Edition (SQL CE) database to SQL Server using Web Matrix

- by Harish Ranganathan

One of the things that is keeping us busy is the Web Camps we are delivering across 5 cities. If you are a reader of this blog, and also attended one of these web camps, there is a good chance that you have seen me since I was there in all the places, so far. The topics that we cover include Visual Studio 2010 SP1, SQL CE, ASP.NET MVC & HTML5. Whenever I talk about SQL CE, the immediate response is that, people are wow that Microsoft has shipped a FREE compact edition database, which is an embedded database that can be x-copy deployed. If you think, well didn’t Microsoft ship SQL Express which is FREE? The difference is that, SQL Express runs as a service in the machine (if you open SQL Configuration Manager, you can notice that SQL Express is running as a service along with your SQL Server Engine (if you have installed ). This makes it that, even if you are willing to use SQL Express when you deploy your application, it needs to be installed on the production machine (hosting provider) and it needs to run as a service. Many hosters don’t allow such services to run on their space. SQL CE comes as a x-Copy deploy-able database with just a few DLLs required to run it on the machine and they don’t even need to be installed in GAC on the production machine. In fact, if you have Visual Studio 2010 SP1 installed, you can use the “Add Deployable Dependencies” option in Project-Properties and it would detect that SQL CE is something you would probably want to add as a deploy-able dependency for your project. With that, it bundles the required DLLs as a part of the “_bin_deployableAssemblies” folder. So your project can be x-Copy deployed and just works fine. However, SQL CE has the limit of 4GB storage space. Real world applications often require more than just 4GB of data storage and it often turns out that people would like to use SQL CE for development/ramp up stages but would like to migrate to full fledged SQL Server after a while. So, its only natural that the question arises “How do I move my SQL CE database to SQL Server” And honestly, it doesn’t come across as a straight forward support. I was talking to Ambrish Mishra (PM in SQL CE Team, Hyderabad) since I got this question in almost all the places where we talked about SQL CE. He was kind enough to demonstrate how this can be accomplished using Web Matrix. Open Web Matrix (Web Matrix can be installed for free from www.microsoft.com/web) and click on “Site from Template” Click on the “Bakery” template (since by default it uses a SQL CE database and has all the required sample data) and click “Ok”. In the project, you can navigate to the Database tab and will be able to find that the Bakery site uses a SQL CE database “bakery.sdf” Select the “bakery.sdf” and you will be able to see the “Migrate” button on the top right Once you click on the “Migrate” button, you will notice that the popup wizard opens up and by default is configured for SQL Express. You can edit the same to point to your local SQL Server instance, or a remote server. Upon filling in the Server Name, Username and Password, when you click “Ok”, couple of things happen. 1. The database is migrated to SQL Server (local or remote – subject to permissions on remote server). You can open up SQL Server Management Studio and connect to the server to verify that the “bakery” database exists under “Databases” node. 2. You can also notice that in Web Matrix, when you navigate to the “Files” tab and open up the web.config file, connection string now points to the SQL Server instance (yes, the Migrate button was smart enough to make this change too ) And there it is, your SQL Server Compact Edition database, now migrated to SQL Server!! In a future post, I would explain the steps involved when using Visual Studio. Cheers !!!

Why you need to tag your build servers in TFS

- by Martin Hinshelwood

At SSW we use gated check-in for all of our projects. The benefits are based on the number of developers you have working on your project. Lets say you have 30 developers and each developer breaks the build once per month. That could mean that you have a broken build every day! Gated check-ins help, but they have a down side that manifests as queued builds and moaning developers. The way to combat this is to have more build servers, but with that comes complexity. Inevitably you will need to install components that you would expect to be installed on target computers, but how do you keep track of which build servers have which bits? What about a geographically diverse team? If you have a centrally controlled infrastructure you might have build servers in multiple regions and you don’t want teams in Sydney copying files from Beijing and vice a versa on a regular basis. So, what is the answer. Its Tags. You can add a set of Tags to your agents and then set which tags to look for in the build definition. Figure: Open up your Build Controller Manager Select “Build | Manage Build Controllers…” to get a list of all of your controllers and he build agents that are associated with them. Figure: the list of build agents and their controllers Each of these Agents might be subtly different. For example only one of these agents has FTP software installed. This software is required for only one of the many builds we have set up. My ethos for build servers is to keep them as clean as possible and not to install anything that is not absolutely necessary. For me that means anything that does not add a *.target file is suspect, and should really be under version control and called via the command line from there. So, some of the things you may install are: Silverlight 4 SDK Visual Studio 2010 Visual Studio 2008 WIX etc You should not install things that will not end up on the target users computer. For a website that means something different to a client than to a server, but I am sure you get the idea. One thing you can do to make things easier is to create a tag for each of the things that you install. that way developers can find the things they need. We may change to using a more generic tagging structure (Like “Web Application” or “WinForms Application”) if this gets too unwieldy, but for now the list of tags is limited. Figure: Tags associated with one of our build agents Once you have your Build Agents all tagged up ALL your builds will start to fail This is because the default setting for a build is to look for an Agent that exactly matches the tags for the build, and we have not added any yet. The quick way to fix this is to change the “Tag Comparison Operator” from “ExactMatch” to “MatchAtLease” to get your build immediately working. Figure: Tag Comparison Operator changes to MatchAtLeast to get builds to run. The next thing to do is look for specific tags. You just select from the list of available tags and the controller will make sure you get to a build agent that uses them. Figure: I want Silverlight, VS2010 and WIX, but do not care about Location. And there you go, you can now have build agents for different purposes and regions within the same environment. You can also use name filtering, so if you have a good Agent naming convention you can filter by that for regions. For example, your Agents might be “SYDVMAPTFSBP01” and “SYDVMAPTFSBP02” so a name filter of “SYD*” would target all of the Sydney build agents. Figure: Agent names can be used for filtering as well This flexibility will allow you to build better software by reducing the likelihood of not having a certain dependency on the target machines. Figure: Setting the name filter based on server location Used in combination there is a lot of power here to coordinate tens of build servers for multiple projects across multiple regions so your developers get the most out of your environment.

What packages do I need to compile .tex documents using XeLaTeX?

- by maria

Hi I'm aware of the existence of similar threads on this forum. But any of replies mach to my problem. I'm using Ubuntu 10.4 and I hadn't problems with fonts till I've decided to use XeLaTeX instead of LaTeX (cf http://tex.stackexchange.com/questions/12347/typesetting-a-document-using-arabic-script/12358#12358). The problem is that I'm not able to compile any .tex document using XeLaTeX, as well as properly display XeLaTeX documentation. As I've learn thanks to mentioned thread, XeLaTeX uses the fonts availables in general in the system. I was trying yo read fontspec documentation, but it opens in pdf with a lot of white gaps and terminal output (quite long) consist mostly of errors. This are just few lines of it: Error: Missing language pack for 'Adobe-Japan1' mapping Error: Unknown font tag 'F5.1' Error (24124): No font in show Error: Unknown font tag 'F5.1' I was trying to compile simple XeLaTeX file: \documentclass{article} \usepackage{fontspec} \setmainfont{Linux Libertine O} \begin{document} Hello World! \end{document} without succes.

Two small issues with Windows Phone 7 ApplicationBar buttons (and workaround)

- by Laurent Bugnion

When you work with the ApplicationBar in Windows Phone 7, you notice very fast that it is not quite a component like the others. For example, the ApplicationBarIconButton element is not a dependency object, which causes issues because it is not possible to add attached properties to it. Here are two other issues I stumbled upon, and what workaround I used to make it work anyway. Finding a button by name returns null Since the ApplicationBar is not in the tree of the Silverlight page, finding an element by name fails. For example consider the following code: <phoneNavigation:PhoneApplicationPage.ApplicationBar> <shell:ApplicationBar> <shell:ApplicationBar.Buttons> <shell:ApplicationBarIconButton IconUri="/Resources/edit.png" Click="EditButtonClick" x:Name="EditButton"/> <shell:ApplicationBarIconButton IconUri="/Resources/cancel.png" Click="CancelButtonClick" x:Name="CancelButton"/> </shell:ApplicationBar.Buttons> </shell:ApplicationBar> </phoneNavigation:PhoneApplicationPage.ApplicationBar> with private void EditButtonClick( object sender, EventArgs e) { CancelButton.IsEnabled = false; // Fails, CancelButton is always null } The CancelButton, even though it is named through an x:Name attribute, and even though it appears in Intellisense in the code behind, is null when it is needed. To solve the issue, I use the following code: public enum IconButton { Edit = 0, Cancel = 1 } public ApplicationBarIconButton GetButton( IconButton which) { return ApplicationBar.Buttons[(int) which] as ApplicationBarIconButton; } private void EditButtonClick( object sender, EventArgs e) { GetButton(IconButton.Cancel).IsEnabled = false; } Updating a Binding when the icon button is clicked In Silverlight, a Binding on a TextBox’s Text property can only be updated in two circumstances: When the TextBox loses the focus. Explicitly by placing a call in code. In WPF, there is a third option, updating the Binding every time that the Text property changes (i.e. every time that the user types a character). Unfortunately this option is not available in Silverlight). To select option 1, 2 (and in WPF, 3), you use the Mode property of the Binding class. The issue here is that pressing a button on the ApplicationBar does not remove the focus from the TextBox where the user is currently typing. If the button is a Save button, this is super annoying: The Binding does not get updated on the data object, the object is saved anyway with the old state, and noone understands what just happened. In order to solve this, you can make sure that the Binding is updated explicitly when the button is pressed, with the following code: private void SaveButtonClick(object sender, EventArgs e) { // Force update binding first var binding = MessageTextBox.GetBindingExpression( TextBox.TextProperty); binding.UpdateSource(); // Property was updated for sure, now we can save var vm = DataContext as MainViewModel; vm.Save(); } Obviously this is less maintainable than the usual way to do things in Silverlight. So be careful when using the ApplicationBar and remember that it is not a Silverlight element like the others!! Happy coding!

Oredev 2011 Trip Report

- by arungupta

Oredev had its seventh annual conference in the city of Malmo, Sweden last week. The name "Oredev" signifies to the part that Malmo is connected with Copenhagen with Oresund bridge. There were about 1000 attendees with several speakers from all over the world. The first two days were hands-on workshops and the next three days were sessions. There were different tracks such as Java, Windows 8, .NET, Smart Phones, Architecture, Collaboration, and Entrepreneurship. And then there was Xtra(ck) which had interesting sessions not directly related to technology. I gave two slide-free talks in the Java track. The first one showed how to build an end-to-end Java EE 6 application using NetBeans and GlassFish. The complete instructions to build the application are explained in detail here. This 3-tier application used Java Persistence API, Enterprsie Java Beans, Servlet, Contexts and Dependency Injection, JavaServer Faces, and Java API for RESTful Services. The source code built during the application can be downloaded here (LINK TBD). The second session, slide-free again, showed how to take a Java EE 6 application into production using GlassFish cluster. It explained: Create a 2-instance GlassFish cluster Front-end with a Web server and a load balancer Demonstrate session replication and fail over Monitor the application using JavaScript The complete instructions for this session are available here. Oredev has an interesting way of collecting attendee feedback. The attendees drop a green, yellow, or red card in a bucket as they walk out of the session. Not everybody votes but most do. Other than the instantaneous feedback provided on twitter, this mechanism provides a more coarse grained feedback loop as well. The first talk had about 67 attendees (with 23 green and 7 yellow) and the second one had 22 (11 green and 11 yellow). The speakers' dinner is a good highlight of the conference. It is arranged in the historic city hall and the mayor welcomed all the speakers. As you can see in the pictures, it is a very royal building with lots of history behind it. Fortunately the dinner was a buffet with a much better variety unlike last year where only black soup and geese were served, which was quite cultural BTW ;-) The sauna in 85F, skinny dipping in 35F ocean and alternating between them at Kallbadhus is always very Swedish. Also spent a short evening at a friend's house socializing with other speaker/attendees, drinking Glogg, and eating Pepperkakor. The welcome packet at the hotel also included cinnamon rolls, recommended to drink with cold milk, for a little more taste of Swedish culture. Something different at this conference was how artists from Image Think were visually capturing all the keynote speakers using images on whiteboards. Here are the images captured for Alexis Ohanian (Reddit co-founder and now running Hipmunk): Unfortunately I could not spend much time engaging with other speakers or attendees because was busy preparing a new hands-on lab material. But was able to spend some time with Matthew Mccullough, Micahel Tiberg, Magnus Martensson, Mattias Karlsson, Corey Haines, Patrick Kua, Charles Nutter, Tushara, Pradeep, Shmuel, and several other folks. Here are a few pictures captured from the event: And the complete album here: Thank you Matthias, Emily, and Kathy for putting up a great show and giving me an opportunity to speak at Oredev. I hope to be back next year with a more vibrant representation of Java - the language and the ecosystem!

Should I break contract early?

- by cbang

About 7 months ago I made the switch from a 5 year permie role (as a support developer in C#) to a contract role. I did this because I was stagnating in my old role. The extra cash contracting is really helping too. Unfortunately my team leader has taken a dislike to me from day 1. He regularly tells me I went out contracting too early, and frequently remarks that people in their 20's have no idea what they are talking about (I am 29). I was recently given the task of configuring our reports via our in house reporting library. It works off of a database driven criteria base, with controls being loaded as needed. The configs can get fairly complex, with controls having various levels of dependency on each other. I had a short time frame to get 50 reports working, and I was told to just get the basic configuration done, after which they will be handed over to the reporting team for fine tuning, then the test team. Our updated system was deployed 2 weeks ago, and it turned out that about 15 reports had issues causing incorrect data to be returned. Upon investigation I discovered that the reporting team hadn't even looked at them, and the test team hadn't bothered to test the reports. In spite of this, my team leader has told me that it is 100% my fault. As a result, our help desk got hit hard. I worked back until 2am that night to fix the highest priority issues (on my wedding anniversary!). The next day I arrive at work at 7:45 am to continue with the fixes. I got no thanks, but keep getting repeatedly told by my manager that "I fucked up" and "this is all my fault". I told my team leader I would spend part of my weekend working to fix the remaining issues. His response was "so you fucking should! you fucked it all up!" in front of the rest of the team. I responded "No worries." and left. I spent a decent chunk of my weekend working on it. Within 2 business days of finding out about the issues, I had all the medium and high priority issues fixed. The only comments my team leader has made to me in the last 2 weeks is to tell me how I have caused a big mess, and to tell me it was all my fault. I get this multiple times a day. If I make any jokes to anyone else in the team, I get told not to be a smartass... even though the rest of the team jokes throughout the day. Apart from that, all I get is angry looks any time I am anywhere near the guy. I don't give any response other than "alright" or silence when he starts giving me a hard time. Today we found out that the pilot release for the next stage has been pushed back. My team leader has said this was caused by me (but the higher ups said no such thing). He also said I have "no understanding of the ramifications of my actions". My question is, should I break contract (I am contracted until June 30) and find another role? No one else in my team will speak up in my favour, as they are contractors too and have no interest in rocking the boat. I could complain to my team leaders boss, but I can't see that helping, as I will still be stuck in the same team. As this is my first contract, I imagine getting the next one will be hard without a reference. I can't figure out if this guy is trying to get me fired up to provoke a confrontation (the guy loves conflict), or if he is just venting anger, or what. Copping this blame day after day is really wearing me down and making me depressed... especially since I have a wife and kid to support).

What's up with LDoms: Part 9 - Direct IO

- by Stefan Hinker

In the last article of this series, we discussed the most general of all physical IO options available for LDoms, root domains. Now, let's have a short look at the next level of granularity: Virtualizing individual PCIe slots. In the LDoms terminology, this feature is called "Direct IO" or DIO. It is very similar to root domains, but instead of reassigning ownership of a complete root complex, it only moves a single PCIe slot or endpoint device to a different domain. Let's look again at hardware available to mars in the original configuration: root@sun:~# ldm ls-io NAME TYPE BUS DOMAIN STATUS ---- ---- --- ------ ------ pci_0 BUS pci_0 primary pci_1 BUS pci_1 primary pci_2 BUS pci_2 primary pci_3 BUS pci_3 primary /SYS/MB/PCIE1 PCIE pci_0 primary EMP /SYS/MB/SASHBA0 PCIE pci_0 primary OCC /SYS/MB/NET0 PCIE pci_0 primary OCC /SYS/MB/PCIE5 PCIE pci_1 primary EMP /SYS/MB/PCIE6 PCIE pci_1 primary EMP /SYS/MB/PCIE7 PCIE pci_1 primary EMP /SYS/MB/PCIE2 PCIE pci_2 primary EMP /SYS/MB/PCIE3 PCIE pci_2 primary OCC /SYS/MB/PCIE4 PCIE pci_2 primary EMP /SYS/MB/PCIE8 PCIE pci_3 primary EMP /SYS/MB/SASHBA1 PCIE pci_3 primary OCC /SYS/MB/NET2 PCIE pci_3 primary OCC /SYS/MB/NET0/IOVNET.PF0 PF pci_0 primary /SYS/MB/NET0/IOVNET.PF1 PF pci_0 primary /SYS/MB/NET2/IOVNET.PF0 PF pci_3 primary /SYS/MB/NET2/IOVNET.PF1 PF pci_3 primary All of the "PCIE" type devices are available for SDIO, with a few limitations. If the device is a slot, the card in that slot must support the DIO feature. The documentation lists all such cards. Moving a slot to a different domain works just like moving a PCI root complex. Again, this is not a dynamic process and includes reboots of the affected domains. The resulting configuration is nicely shown in a diagram in the Admin Guide: There are several important things to note and consider here: The domain receiving the slot/endpoint device turns into an IO domain in LDoms terminology, because it now owns some physical IO hardware. Solaris will create nodes for this hardware under /devices. This includes entries for the virtual PCI root complex (pci_0 in the diagram) and anything between it and the actual endpoint device. It is very important to understand that all of this PCIe infrastructure is virtual only! Only the actual endpoint devices are true physical hardware. There is an implicit dependency between the guest owning the endpoint device and the root domain owning the real PCIe infrastructure: Only if the root domain is up and running, will the guest domain have access to the endpoint device. The root domain is still responsible for resetting and configuring the PCIe infrastructure (root complex, PCIe level configurations, error handling etc.) because it owns this part of the physical infrastructure. This also means that if the root domain needs to reset the PCIe root complex for any reason (typically a reboot of the root domain) it will reset and thus disrupt the operation of the endpoint device owned by the guest domain. The result in the guest is not predictable. I recommend to configure the resulting behaviour of the guest using domain dependencies as described in the Admin Guide in Chapter "Configuring Domain Dependencies". Please consult the Admin Guide in Section "Creating an I/O Domain by Assigning PCIe Endpoint Devices" for all the details! As you can see, there are several restrictions for this feature. It was introduced in LDoms 2.0, mainly to allow the configuration of guest domains that need access to tape devices. Today, with the higher number of PCIe root complexes and the availability of SR-IOV, the need to use this feature is declining. I personally do not recommend to use it, mainly because of the drawbacks of the depencies on the root domain and because it can be replaced with SR-IOV (although then with similar limitations). This was a rather short entry, more for completeness. I believe that DIO can usually be replaced by SR-IOV, which is much more flexible. I will cover SR-IOV in the next section of this blog series.

Abstracting entity caching in XNA

- by Grofit

I am in a situation where I am writing a framework in XNA and there will be quite a lot of static (ish) content which wont render that often. Now I am trying to take the same sort of approach I would use when doing non game development, where I don't even think about caching until I have finished my application and realise there is a performance problem and then implement a layer of caching over whatever needs it, but wrap it up so nothing is aware its happening. However in XNA the way we would usually cache would be drawing our objects to a texture and invalidating after a change occurs. So if you assume an interface like so: public interface IGameComponent { void Update(TimeSpan elapsedTime); void Render(GraphicsDevice graphicsDevice); } public class ContainerComponent : IGameComponent { public IList<IGameComponent> ChildComponents { get; private set; } // Assume constructor public void Update(TimeSpan elapsedTime) { // Update anything that needs it } public void Render(GraphicsDevice graphicsDevice) { foreach(var component in ChildComponents) { // draw every component } } } Then I was under the assumption that we just draw everything directly to the screen, then when performance becomes an issue we just add a new implementation of the above like so: public class CacheableContainerComponent : IGameComponent { private Texture2D cachedOutput; private bool hasChanged; public IList<IGameComponent> ChildComponents { get; private set; } // Assume constructor public void Update(TimeSpan elapsedTime) { // Update anything that needs it // set hasChanged to true if required } public void Render(GraphicsDevice graphicsDevice) { if(hasChanged) { CacheComponents(graphicsDevice); } // Draw cached output } private void CacheComponents(GraphicsDevice graphicsDevice) { // Clean up existing cache if needed var cachedOutput = new RenderTarget2D(...); graphicsDevice.SetRenderTarget(renderTarget); foreach(var component in ChildComponents) { // draw every component } graphicsDevice.SetRenderTarget(null); } } Now in this example you could inherit, but your Update may become a bit tricky then without changing your base class to alert you if you had changed, but it is up to each scenario to choose if its inheritance/implementation or composition. Also the above implementation will re-cache within the rendering cycle, which may cause performance stutters but its just an example of the scenario... Ignoring those facts as you can see that in this example you could use a cache-able component or a non cache-able one, the rest of the framework needs not know. The problem here is that if lets say this component is drawn mid way through the game rendering, other items will already be within the default drawing buffer, so me doing this would discard them, unless I set it to be persisted, which I hear is a big no no on the Xbox. So is there a way to have my cake and eat it here? One simple solution to this is make an ICacheable interface which exposes a cache method, but then to make any use of this interface you would need the rest of the framework to be cache aware, and check if it can cache, and to then do so. Which then means you are polluting and changing your main implementations to account for and deal with this cache... I am also employing Dependency Injection for alot of high level components so these new cache-able objects would be spat out from that, meaning no where in the actual game would they know they are caching... if that makes sense. Just incase anyone asked how I expected to keep it cache aware when I would need to new up a cachable entity.

Ask the Readers: Would You Be Willing to Give Windows Up and Use a Different O.S.?

- by Asian Angel

When it comes to computers, Windows definitely rules the desktop in comparison to other operating systems. What we would like to know this week is if you would actually be willing to give up using Windows altogether and move to a different operating system on your computers. Note: This week’s Ask the Readers post is posing a hypothetical situation, so please refrain from starting arguments or a flame war in the comments. Good reasoned discussion is always welcome. There is no doubt that Windows is the dominant operating system in use today. Everywhere you go or look it is easy to find computers with Windows installed such as at work, home, the library, government offices, and more. For many people it is the operating system that they know and are comfortable with, which makes changing to a different operating system less appealing. Adding to the preference for Windows (or dependency based on your view) is the custom software that many businesses use on a daily basis. Throw in the high volume of people who depend on and use Microsoft Office as a standard for their business documents and it is little wonder that Windows is so dominant. So what would you use if you did decide to take a break from or permanently move away from Windows? If your choice is Linux then you have a large and wonderful variety of distributions to choose from based on what you want out of your system. Want a distribution that is easy to work with? You could choose Ubuntu, Linux Mint, or others that are engineered to be ready to go “out of the box”. Like a challenge? Perhaps Arch Linux is more your style. One of the most attractive features of all about Linux is the price…it is very hard to beat free! Maybe Mac OS X sounds like the perfect choice. It has a certain mystique and elegance associated with it and many OS X fans refuse to use anything else if given a choice. Then there is the soon to be released Chrome OS with its’ emphasis on cloud computing. This is a system that is definitely focused on being as low-maintenance and hassle-free as possible. Quick on, quick off, minimalist, and made to be portable. All of the system’s updates will occur automatically leaving you free to work and play in the cloud. But it does have its’ limitations…no installing all of those custom apps that you love using on Windows or other systems…it is literally all about the browsing window and web apps. So there you have it. If the opportunity presented itself would you, could you give Windows up and use a different operating system? Would it be easy or hard for you to do? Perhaps it would not really matter so long as you could do what you needed or wanted to do on a computer. And maybe this is the perfect time to try something new and find out…that new favorite operating system could be just an install disc away. Let us know your thoughts in the comments!

Iterative and Incremental Principle Series 4: Iteration Planning – (a.k.a What should I do today?)

- by llowitz

Welcome back to the fourth of a five part series on applying the Iteration and Incremental principle. During the last segment, we discussed how the Implementation Plan includes the number of the iterations for a project, but not the specifics about what will occur during each iteration. Today, we will explore Iteration Planning and discuss how and when to plan your iterations. As mentioned yesterday, OUM prescribes initially planning your project approach at a high level by creating an Implementation Plan. As the project moves through the lifecycle, the plan is progressively refined. Specifically, the details of each iteration is planned prior to the iteration start. The Iteration Plan starts by identifying the iteration goal. An example of an iteration goal during the OUM Elaboration Phase may be to complete the RD.140.2 Create Requirements Specification for a specific set of requirements. Another project may determine that their iteration goal is to focus on a smaller set of requirements, but to complete both the RD.140.2 Create Requirements Specification and the AN.100.1 Prepare Analysis Specification. In an OUM project, the Iteration Plan needs to identify both the iteration goal – how far along the implementation lifecycle you plan to be, and the scope of work for the iteration. Since each iteration typically ranges from 2 weeks to 6 weeks, it is important to identify a scope of work that is achievable, yet challenging, given the iteration goal and timeframe. OUM provides specific guidelines and techniques to help prioritize the scope of work based on criteria such as risk, complexity, customer priority and dependency. In OUM, this prioritization helps focus early iterations on the high risk, architecturally significant items helping to mitigate overall project risk. Central to the prioritization is the MoSCoW (Must Have, Should Have, Could Have, and Won’t Have) list. The result of the MoSCoW prioritization is an Iteration Group. This is a scope of work to be worked on as a group during one or more iterations. As I mentioned during yesterday’s blog, it is pointless to plan my daily exercise in advance since several factors, including the weather, influence what exercise I perform each day. Therefore, every morning I perform Iteration Planning. My “Iteration Plan” includes the type of exercise for the day (run, bike, elliptical), whether I will exercise outside or at the gym, and how many interval sets I plan to complete. I use several factors to prioritize the type of exercise that I perform each day. Since running outside is my highest priority, I try to complete it early in the week to minimize the risk of not meeting my overall goal of doing it twice each week. Regardless of the specific exercise I select, I follow the guidelines in my Implementation Plan by applying the 6-minute interval sets. Just as in OUM, the iteration goal should be in context of the overall Implementation Plan, and the iteration goal should move the project closer to achieving the phase milestone goals. Having an Implementation Plan details the strategy of what I plan to do and keeps me on track, while the Iteration Plan affords me the flexibility to juggle what I do each day based on external influences thus maximizing my overall success. Tomorrow I’ll conclude the series on applying the Iterative and Incremental approach by discussing how to manage the iteration duration and highlighting some benefits of applying this principle.

Valuing "Working Software over Comprehensive Documentation"

As Oracle's chief methodologist, that might seem a self-deprecating attitude. After all, the agile manifesto tells us that we should value "individuals and interactions" over "processes and tools." My job includes process development. I also subscribe to ideas put forth in a number of subsequent works including Balancing Agility and Discipline: A Guide for the Perplexed (Boehm/Turner, Addison-Wesley) and Agile Project Management: Creating Innovative Products (Highsmith, Addison-Wesley). Both of these books talk about finding the right balance between "agility and discipline" or between a "predictive and adaptive" project approach. So there still seems to be a place for us in creating the Oracle Unified Method (OUM) to become the "single method framework that supports the successful implementation of every Oracle product." After all, the real idea is to apply just enough ceremony and produce just enough documentation to suit the needs of the particular project that supports an enterprise in moving toward its desired future state. The thing I've been struggling with - and the thing I'd like to hear from you about right now - is the prevalence of an ongoing obsession with "documents." OUM provides a comprehensive set of guidance for an iterative and incremental approach to engineering and implementing software systems. Our intent is first to support the information technology system implementation and, as necessary, support the creation of documentation. OUM, therefore, includes a supporting set of document templates. Our guidance is to employ those templates, sparingly, as needed; not create piles of documentation that you're not gonna (sic) need. In other words, don't serve the method, make the method serve you. Yet, there seems to be a "gimme" mentality in some circles that if you give me a sample document - or better yet - a repository of samples - then I will be able to do anything cheaply and quickly. The notion is certainly appealing AND reuse can save time. Plus, documents are a lowest common denominator way of packaging reusable stuff. However, without sustained investment and management I've seen "reuse repositories" turn quickly into garbage heaps. So, I remain a skeptic. I agree that providing document examples that promote consistency is helpful. However, there may be too much emphasis on the documents themselves and not enough on creating a system that meets the evolving needs of the business. How can we shift the emphasis toward working software and away from our dependency on documents - especially on large, complex implementation projects - while still supporting the need for documentation? I'd like to hear your thoughts.

Process Is The New App by Leon Smiers

- by JuergenKress

Process-on-the-Fly #2 - Process is the New App The next generation of business process management and business rules management tools is so powerful that it actually can be seen as the successor to custom-built applications. Being able to define detailed process, flows, decision trees and business helps on both the business and IT side to create powerful, differentiating solutions that would have required extensive custom coding in the past. Now much of the definition can be done ‘on the fly,’ using visual models and (semi) natural language in the nearest proximity to the business. Over the years, ERP systems have been customized to enter organization-specific functionality into the ERP application. This leads to better support for the business, but at the same time involves higher costs for maintenance, high dependency on the personnel involved in this customization, long timelines to deliver change to the system and increased risk involved in upgrading the ERP system. However, the best of both worlds can be created by bringing back the functionality to out-of-the-box usage of the ERP system and at the same time introducing change and flexibility by means of externalized 'Process Apps' in direct connection with the ERP system. The ERP system (or legacy bespoke system, for that matter) is used as originally intended and designed, resulting in more predictable behavior of the system related to usage and performance, and clearly can be maintained in a more standardized and cost-effective way. The Prrocess App externalizes the needed functionality into a highly customizable application outside the ERP for which it is supported by rules engines, task inboxes and can be delivered to different channels. The reasons for needing Process Apps may include the following: The ERP system just doesn't deliver this functionality in a specific industry; the volatility of changing certain functionality is high; or an umbrella type of functionality across (ERP) silos is needed. An example of bringing all this together is around the hiring process for a new employee at a university. Oracle PeopleSoft HCM could be used as the HR system to store all employee details. In the hiring process, an authorization scheme is involved for getting the approval to create a contract for the employee-to-be. In the university world, this authorization scheme is complex and involves faculties/colleges (with different organizational structures) and cross-faculty organizational structures. Including such an authorization scheme into PeopleSoft would require a lot of customization. By adding a handle inside PeopleSoft towards an externalized authorization Process App, the execution of the authorization of the employee is done outside the ERP: in a tool that is aimed to deliver approval schemes via a worklist-type of application. The Process App here works as an add-on to the PeopleSoft system, but can also be extended to support the full lifecycle of the end-to-end hiring process with the possibility to involve multiple applications. The actual core functionality is kept in the supporting ERP systems, while at the same time the Process App acts as an umbrella function to control the end-to-end flow and give insight into the efficiency of the end-to-end process.

- by JuergenKress

In the last 12 years Link Consulting has been making its presence in specific areas such as Governance and Architecture, both in terms of practices and methodologies, products, know-how and technological expertise. The Enterprise Architecture Management System - Oracle Enterprise Edition (EAMS - OER Edition) is the result of this experience and combines the architecture management solution with OER in order to deliver a product specialized for SOA Governance that gathers the better of two worlds in solution that enables SOA Governance projects, initiatives and programs. Enterprise Architecture Management System Enterprise Architecture Management System (EAMS), is an automation based solution that enables the efficient management of Enterprise Architectures. The solution uses configured enterprise repositories and takes advantages of its features to provide automation capabilities to the users. EAMS provides capabilities to create/customize/analyze repository data, architectural blueprints, reports and analytic charts. Oracle Enterprise Repository Oracle Enterprise Repository (OER) is one of the major and central elements of the Oracle SOA Governance solution. Oracle Enterprise Repository provides the tools to manage and govern the metadata for any type of software asset, from business processes and services to patterns, frameworks, applications, components, and models. OER maps the relationships and inter-dependencies that connect those assets to improve impact analysis, promote and optimize their reuse, and measure their impact on the bottom line. It provides the visibility, feedback, controls, and analytics to keep your SOA on track to deliver business value. The intense focus on automation helps to overcome barriers to SOA adoption and streamline governance throughout the lifecycle. Core capabilities of the OER include: Asset Management Asset Lifecycle Management Usage Tracking Service Discovery Version Management Dependency Analysis Portfolio Management EAMS - OER Edition The solution takes the advantages and features from both products and combines them in a symbiotic tool that enhances the quality of SOA Governance Initiatives and Programs. EAMS is able to produce a vast number of outputs by combining its analytical engine, SOA-specific configurations and the assets in OER and other related tools, catalogs and repositories. The configurations encompass not only the extendable parametrization of the metadata but also fully configurable blueprints, PowerPoint reports, charts and queries. The SOA blueprints The solution comes with a set of predefined architectural representations that help the organization better perceive their SOA landscape. More blueprints can be easily created in order to accommodate the organizations needs in terms of detail, audience and metadata. Charts & Dashboards The solution encompasses a set of predefined charts and dashboards that promote a more agile way to control and explore the assets.

It's at its 13th download attempt at the moment of writing. The actual downloads seem to be done just fine, but whatever it does after downloading seems to be failing. I tried removing openjdk-6, but then it wanted to install openjdk-7 instead, with the same result, hanging at openjdk-7-jre-headless instead. I also tried changing servers from my local (Danish) to the main server. No luck. It's also keeping me from upgrading alle the other packages. What to do? Update After following instructions in the answer by @lpanebr, it is now stuck at the linux-firmware package. So, maybe it's a more general problem than being related to specific package(s)? Although it did download some packages without problems before getting stuck at linux-firmware.

XNA Multiplayer Games and Networking

- by JoshReuben

· XNA communication must by default be lightweight – if you are syncing game state between players from the Game.Update method, you must minimize traffic. That game loop may be firing 60 times a second and player 5 needs to know if his tank has collided with any player 3 and the angle of that gun turret. There are no WCF ServiceContract / DataContract niceties here, but at the same time the XNA networking stack simplifies the details. The payload must be simplistic - just an ordered set of numbers that you would map to meaningful enum values upon deserialization. Overview · XNA allows you to create and join multiplayer game sessions, to manage game state across clients, and to interact with the friends list · Dependency on Gamer Services - to receive notifications such as sign-in status changes and game invitations · two types of online multiplayer games: system link game sessions (LAN) and LIVE sessions (WAN). · Minimum dev requirements: 1 Xbox 360 console + Creators Club membership to test network code - run 1 instance of game on Xbox 360, and 1 on a Windows-based computer Network Sessions · A network session is made up of players in a game + up to 8 arbitrary integer properties describing the session · create custom enums – (e.g. GameMode, SkillLevel) as keys in NetworkSessionProperties collection · Player state: lobby, in-play Session Types · local session - for split-screen gaming - requires no network traffic. · system link session - connects multiple gaming machines over a local subnet. · Xbox LIVE multiplayer session - occurs on the Internet. Ranked or unranked Session Updates · NetworkSession class Update method - must be called once per frame. · performs the following actions: o Sends the network packets. o Changes the session state. o Raises the managed events for any significant state changes. o Returns the incoming packet data. · synchronize the session à packet-received and state-change events à no threading issues Session Config · Session host - gaming machine that creates the session. XNA handles host migration · NetworkSession properties: AllowJoinInProgress , AllowHostMigration · NetworkSession groups: AllGamers, LocalGamers, RemoteGamers Subscribe to NetworkSession events · GamerJoined · GamerLeft · GameStarted · GameEnded – use to return to lobby · SessionEnded – use to return to title screen Create a Session session = NetworkSession.Create( NetworkSessionType.SystemLink, maximumLocalPlayers, maximumGamers, privateGamerSlots, sessionProperties ); Start a Session if (session.IsHost) { if (session.IsEveryoneReady) { session.StartGame(); foreach (var gamer in SignedInGamer.SignedInGamers) { gamer.Presence.PresenceMode = GamerPresenceMode.InCombat; Find a Network Session AvailableNetworkSessionCollection availableSessions = NetworkSession.Find( NetworkSessionType.SystemLink, maximumLocalPlayers, networkSessionProperties); availableSessions.AllowJoinInProgress = true; Join a Network Session NetworkSession session = NetworkSession.Join( availableSessions[selectedSessionIndex]); Sending Network Data var packetWriter = new PacketWriter(); foreach (LocalNetworkGamer gamer in session.LocalGamers) { // Get the tank associated with this player.
