• Gain Total Control of Systems running Oracle Linux

  - by Anand Akela

  Oracle Linux is the best Linux for enterprise computing needs and Oracle Enterprise Manager enables enterprises to gain total control over systems running Oracle Linux. Linux Management functionality is available as part of Oracle Enterprise Manager 12c and is available to Oracle Linux Basic and Premier Support customers at no cost. The solution provides an integrated and cost-effective solution for complete Linux systems lifecycle management and delivers comprehensive provisioning, patching, monitoring, and administration capabilities via a single, web-based user interface thus significantly reducing the complexity and cost associated with managing Linux operating system environments. Many enterprises are transforming their IT infrastructure from multiple independent datacenters to an Infrastructure-as-a-Service (IaaS) model, in which shared pools of compute and storage are made available to end-users on a self-service basis. While providing significant improvements when implemented properly, this strategy introduces change and complexity at a time when datacenters are already understaffed and overburdened. To aid in this transformation, IT managers need the proper tools to help them provide the array of IT capabilities required throughout the organization without stretching their staff and budget to the limit. Oracle Enterprise Manager 12c offers  the advanced capabilities to enable IT departments and end-users to take advantage of many benefits and cost savings of IaaS. Oracle Enterprise Manager Ops Center 12c addresses this challenge with a converged approach that integrates systems management across the infrastructure stack, helping organizations to streamline operations, increase productivity, and reduce system downtime.  You can see the Linux management functionality in action by watching the latest integrated Linux management demo .

• ASP.NET: Building tree picker dialog using jQuery UI and TreeView control

  - by DigiMortal

  Selecting things from dialogs and data represented as trees are very common things we see in business applications. In this posting I will show you how to use ASP.NET TreeView control and jQuery UI dialog component to build picker dialog that hosts tree data. Source code You can find working example with source code from my examples repository in GitHub. Please feel free to give me feedback about my examples. Source code repository GitHub Building dialog box As I don’t like to invent wheels then I will use jQuery UI to solve the question related to dialogs. If you are not sure how to include jQuery UI to your page then take a look at source code - GitHub also allows you to browse files without downloading them. I add some jQuery based JavaScript to my page head to get dialog and button work. <script type="text/javascript">     $(function () {         $("#dialog-form").dialog({             autoOpen: false,             modal: true         });         $("#pick-node")             .button()             .click(function () {                 $("#dialog-form").dialog("open");                 return false;             });     }); </script> Here is the mark-up of our form’s main content area. <div id="dialog-form" title="Select node">     <asp:TreeView ID="TreeView1" runat="server" ShowLines="True"          ClientIDMode="Static" HoverNodeStyle-CssClass="SelectedNode">         <Nodes>             <asp:TreeNode Text="Root" Value="Root">                 <asp:TreeNode Text="Child1" Value="Child1">                     <asp:TreeNode Text="Child1.1" Value="Child1.1" />                     <asp:TreeNode Text="Child1.2" Value="Child1.2" />                 </asp:TreeNode>                 <asp:TreeNode Text="Child2" Value="Child2">                     <asp:TreeNode Text="Child2.1" Value="Child2.1" />                     <asp:TreeNode Text="Child2.2" Value="Child2.2" />                 </asp:TreeNode>             </asp:TreeNode>         </Nodes>     </asp:TreeView>     &nbsp; </div> <button id="pick-node">Pick user</button> Notice that our mark-up is very compact for what we will achieve. If you are going to use it in some real-world application then this mark-up gets even shorter – I am sure that in most cases the data you display in TreeView comes from database or some domain specific data source. Hacking TreeView TreeView needs some little hacking to make it work as client-side component. Be warned that if you need more than I show you here you need to write a lot of JavaScript code. For more advanced scenarios I suggest you to use some jQuery based tree component. This example works for you if you need something done quickly. Number one problem is getting over the postbacks because in our scenario postbacks only screw up things. Also we need to find a way how to let our client-side code to know that something was selected from TreeView. We solve these to problems at same time: let’s move to JavaScript links. We have to make sure that when user clicks the node then information is sent to some JavaScript function. Also we have to make sure that this function returns something that is not processed by browser. My function is here. <script type="text/javascript">     function         $("#dialog-form").dialog("close");         alert("You selected: " + value + " - " + text);         return undefined;     } </script> Notice that this function returns undefined. You get the better idea why I did so if you look at server-side code that corrects NavigateUrl properties of TreeView nodes. protected override void OnPreRender(EventArgs e) {     base.OnPreRender(e);                 if (IsPostBack)         return;     SetSelectNodeUrls(TreeView1.Nodes); } private void SetSelectNodeUrls(TreeNodeCollection nodes) {     foreach (TreeNode node in nodes)     {         node.NavigateUrl = "javascript:selectNode('" + node.Value +                             "','" + node.Text + "');";         SetSelectNodeUrls(node.ChildNodes);     }        } Now we have TreeView that renders nodes the way that postback doesn’t happen anymore. Instead of postback our callback function is used and provided with selected values. In this function we are free to use node text and value as we like. Result I applied some more bells and whistles and sample data to source code to make my sample more informative. So, here is my final dialog box. Seems very basic but it is not hard to make it look more professional using style sheets. Conclusion jQuery components and ASP.NET controls have both their strong sides and weaknesses. In this posting I showed you how you can quickly produce good results when combining jQuery  and ASP.NET controls without pushing to the limits. We used simple hack to get over the postback issue of TreeView control and we made it work as client-side component that is initialized in server. You can find many other good combinations that make your UI more user-friendly and easier to use.

• Source-control your BI Publisher reports

  - by Dmitry Nefedkin

  Version control systems (VCS) like Subversion, Git and the others has been widely adopted and became the must-have tool in any software development project. Source artifacts and checked out, modified, checked in, all the history of changes is tracked by the VCS.  But what if the development tool stores the source/configuration artifacts not in your laptop's hard drive, but in some shared repository instead? Well, we definitely need a way for export/import our artifacts from/to this repository.   Oracle BI Publisher report development approach is based on such a shared repository model (catalog), and starting from BI Publisher 11.1.1.5 Oracle ships Catalog Utility, which can be utilized to export/import the reports from the command line.  To start using the BI Publisher Catalog Utility you should: Go to the file system of the server where BI Publisher binaries has been installed and locate the following file: <MW_HOME>/Oracle_BI1/clients/bipublisher/BIPCatalogUtil.zip Copy the file to your local filesystem and unzip it. I will refer to this unzipped directory as <BIP_CLIENT_DIR> below If you do not want to pass server BI Publisher server URL, username and password during each invocation, modify the corresponding values inside <BIP_CLIENT_DIR>/config/xmlp-client-config.xml Open the terminal window and go to <BIP_CLIENT_DIR>/bin Make sure that the following environment variables are set: JAVA_HOME, ORACLE_HOME Now it's time to run the utility: if you are on Linux - just run BIPCatalogUtil.sh and pass the parameters according to the utility documentation if you are on MS Windows the bad news are that the command script for MS Windows is missing, and support.oracle.com note 1333726.1 says that a temporary solution is "create a .cmd file by setting up a classpath and copying the same commands from the .sh script". The good news are that I've created this script already,  please download the it from GitHub Hope you will find this utility useful during you day-by-day BI Publisher development.

• C++11 Tidbits: access control under SFINAE conditions

  - by Paolo Carlini

  Lately I have been spending quite a bit of time on the SFINAE ("Substitution failure is not an error") features of C++, fixing and tweaking various bits of the GCC implementation. An important missing piece was the implementation of the resolution of DR 1170 which, in a nutshell, mandates that access checking is done as part of the substitution process. Consider: class C { typedef int type; }; template <class T, class = typename T::type> auto f(int) - char; template <class> auto f(...) -> char (&)[2]; static_assert (sizeof(f<C>(0)) == 2, "Ouch"); According to the resolution, the static_assert should not fire, and the snippet should compile successfully. The reason being that the first f overload must be removed from the candidate set because C::type is private to C. On the other hand, before the resolution of DR 1170, the expected behavior was for the first overload to remain in the candidate set, win over the second one, to eventually lead to an access control error (*). GCC mainline (would be 4.8) finally implements the DR, thus benefiting the many modern programming techniques heavily exploiting SFINAE, among which certainly the GNU C++ runtime library itself, which relies on it for the internals of <type_traits> and in several other places. Note that the resolution of the DR is active even in C++98 mode, not just in C++11 mode, because it turned out that the traditional behavior, as implemented in GCC, wasn't fully consistent in all the possible circumstances. (*) In practice, GCC didn't really implement this, the static_assert triggered instead.

• Differences when Running with OutputCache managed module under ASP.NET IIS7.x with Cache-control header

  - by Shawn Cicoria

  This post is to report some differences when using MVC or IHttpHandlers if you’re attempting to set the Cache-control : max-age or s-maxage value under IIS7.x using the HttpResponse.Cache methods. [UPDATE]: 2011-3-14 – The missing piece was calling  Response.Cache.SetSlidingExpiration(true) as follows: context.Response.Cache.SetCacheability(HttpCacheability.Public); context.Response.Cache.SetMaxAge(TimeSpan.FromMinutes(5)); context.Response.ContentType = "image/jpeg"; context.Response.Cache.SetSlidingExpiration(true);   Under IIS7.x if you us one of the following 2 methods, you will only get a Cache-ability of “public”.  public ActionResult Image2() { MemoryStream oStream = new MemoryStream(); using (Bitmap obmp = ImageUtil.RenderImage("Respone.Cache.Setxx calls", 5, DateTime.Now)) { obmp.Save(oStream, ImageFormat.Jpeg); oStream.Position = 0; Response.Cache.SetCacheability(HttpCacheability.Public); Response.Cache.SetMaxAge(TimeSpan.FromMinutes(5)); return new FileStreamResult(oStream, "image/jpeg"); } } Method 2 – which is just a plain old HttpHandler and really isn’t MVC3, but under the same MVC ASP.NET application, same result. public class image : IHttpHandler { public void ProcessRequest(HttpContext context) { using (var image = ImageUtil.RenderImage("called from IHttpHandler direct", 5, DateTime.Now)) { context.Response.Cache.SetCacheability(HttpCacheability.Public); context.Response.Cache.SetMaxAge(TimeSpan.FromMinutes(5)); context.Response.ContentType = "image/jpeg"; image.Save(context.Response.OutputStream, ImageFormat.Jpeg); } } } Using the following under MVC3 (I haven’t tried under earlier versions) will work by applying the OutputCacheAttribute to your Action: [OutputCache(Location = OutputCacheLocation.Any, Duration = 300)] public ActionResult Image1() { MemoryStream oStream = new MemoryStream(); using (Bitmap obmp = ImageUtil.RenderImage("called with OutputCacheAttribute", 5, DateTime.Now)) { obmp.Save(oStream, ImageFormat.Jpeg); oStream.Position = 0; return new FileStreamResult(oStream, "image/jpeg"); } } To remove the “OutputCache” module, you use the following in your web.config: <system.webServer> <validation validateIntegratedModeConfiguration="false"/> <modules runAllManagedModulesForAllRequests="true"> <!--<remove name="OutputCache"/>--> </modules>

• Access Control Service: Home Realm Discovery (HRD) Gotcha

  - by Your DisplayName here!

  I really like ACS2. One feature that is very useful is home realm discovery. ACS provides a Nascar style list as well as discovery based on email addresses. You can take control of the home realm selection process yourself by downloading the JSON feed or by manually setting the home realm parameter. Plenty of options – the only option missing is turning it off… In other words, when you setup your ACS namespace and realm and register identity provider, there is no way to keep the list of identity providers secret. An interested “user” can always retrieve all registered identity provider (using the browser or download the JSON feed). This may not be an issue with web identity providers, but when you use ACS to federate with customers or business partners, you maybe don’t want to disclose that list to the public (or to other customers). This is an adoption blocker for certain situations. I hope this feature will be added soon. In addition I would also like to see a feature I call “home realm aliases”. Some random string that I can use as a whr parameter instead of using the real issuer URI.

• Add control to grid from code behind in Silverlight

  - by Emanuele Bartolesi

  In this post I show how you can easily add a control to a silverlight grid layout from code behind. First you draw the grid in the xaml. <Grid x:Name="LayoutRoot" Background="Red"> <Grid.RowDefinitions> <RowDefinition Height="20"> </RowDefinition> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="300"> </ColumnDefinition> </Grid.ColumnDefinitions> </Grid> Now in the page constructor add the following code. public MainPage() { InitializeComponent(); var myButton = new Button { Name = "btnOk", Content = "Ok", }; myButton.SetValue(Grid.RowProperty, 1); myButton.SetValue(Grid.ColumnProperty, 1); myButton.Click += myButton_Click; LayoutRoot.Children.Add(myButton); } Also add the evento of the button. void myButton_Click(object sender, RoutedEventArgs e) { } The code needs no comment because it’s very simple. The only important thing is the method SetValue because it is used to set XAML attribute of element. For a better understanding I have created an example that you can download from here.

• Character Jump Control

  - by Abdullah Sorathia

  I would like to know how can I control the jump movement of a character in Unity3D. Basically I am trying to program the jump in such a way that while a jump is in progress the character is allowed to move either left or right in mid-air when the corresponding keys are pressed. With my script the character will correctly move to the left when, for example, the left key is pressed, but when the right key is pressed afterwards, the character moves to the right before the movement to the left is completed. Following is the script: void Update () { if(touchingPlatform && Input.GetButtonDown("Jump")){ rigidbody.AddForce(jumpVelocity, ForceMode.VelocityChange); touchingPlatform = false; isJump=true; } //left & right movement Vector3 moveDir = Vector3.zero; if(Input.GetKey ("right")||Input.GetKey ("left")){ moveDir.x = Input.GetAxis("Horizontal"); // get result of AD keys in X if(ShipCurrentSpeed==0) { transform.position += moveDir * 3f * Time.deltaTime; }else if(ShipCurrentSpeed<=15) { transform.position += moveDir * ShipCurrentSpeed * 2f * Time.deltaTime; }else { transform.position += moveDir * 30f * Time.deltaTime; } }

• Terminal/Putty showing control characters (^M) after updating

  - by jaycee48

  I updated my system yesterday afternoon using the recommended updates from Update Manager. After it completed, I shutdown my system and went home for the day. I come in this morning and I am getting control characters displayed when using vi in both the standard terminal emulator, putty, and putty inside of my Windows virtual that I run with VirtualBox. I have made no other system changes and I cannot figure out how this occurred. It's as if every text file I have was created in DOS. I've searched the forums and I haven't found any answers. I am using xterm as my emulator and I checked with 3 of my coworkers and none of them are having this problem so we do not believe it is a server side issue. Especially since I've checked 3 different servers. There's nothing in my .profile other than PATH variables so I'm using the same terminal settings as everyone else. Some files are fine (I can open and read both /etc/environment and my .profile) but most of any kind of server generated log file is trash. Running cat or head on the same file displays the contents without the characters. Any ideas would be appreciated. Thanks.

• In CentOS 4.3 Webmin 1.3000 bandwidth monitoring is eating disk space. How to delete those files?

  - by Silkograph

  I maintain Linux server being used for Mail, Squid and DNS service. Recently I observed that something was eating server disk space. But at last, today I caught the culprit which was consuming the disk by storing large number of files. On this server, Webmin 1.300 is installed. We use Squid proxy and Sarg to monitor Internet access. I always manually clear Sarg generated files under /var/www/html/squid for last few years. But I never realized that Webmin is also storing some kind of bandwidth log files in its' directory structure. I have noticed that under /etc/webmin/bandwidth/hours it has stored more thousands of files since year 2007 totaling about 17 GB. We have used 40 GB HDD for this server machine. My question is how can I delete those (/etc/webmin/bandwidth/hours) files safely?

• Book Review: Programming Windows Identity Foundation

  - by DigiMortal

  Programming Windows Identity Foundation by Vittorio Bertocci is right now the only serious book about Windows Identity Foundation available. I started using Windows Identity Foundation when I made my first experiments on Windows Azure AppFabric Access Control Service. I wanted to generalize the way how people authenticate theirselves to my systems and AppFabric ACS seemed to me like good point where to start. My first steps trying to get things work opened the door to whole new authentication world for me. As I went through different blog postings and articles to get more information I discovered that the thing I am trying to use is the one I am looking for. As best security API for .NET was found I wanted to know more about it and this is how I found Programming Windows Identity Foundation. What’s inside? Programming WIF focuses on architecture, design and implementation of WIF. I think Vittorio is very good at teaching people because you find no too complex topics from the book. You learn more and more as you read and as a good thing you will find that you can also try out your new knowledge on WIF immediately. After giving good overview about WIF author moves on and introduces how to use WIF in ASP.NET applications. You will get complete picture how WIF integrates to ASP.NET request processing pipeline and how you can control the process by yourself. There are two chapters about ASP.NET. First one is more like introduction and the second one goes deeper and deeper until you have very good idea about how to use ASP.NET and WIF together, what issues you may face and how you can configure and extend WIF. Other two chapters cover using WIF with Windows Communication Foundation (WCF) band   Windows Azure. WCF chapter expects that you know WCF very well. This is not introductory chapter for beginners, this is heavy reading if you are not familiar with WCF. The chapter about Windows Azure describes how to use WIF in cloud applications. Last chapter talks about some future developments of WIF and describer some problems and their solutions. Most interesting part of this chapter is section about Silverlight. Who should read this book? Programming WIF is targeted to developers. It does not matter if you are beginner or old bullet-proof professional – every developer should be able to be read this book with no difficulties. I don’t recommend this book to administrators and project managers because they find almost nothing that is related to their work. I strongly recommend this book to all developers who are interested in modern authentication methods on Microsoft platform. The book is written so well that I almost forgot all things around me when I was reading the book. All additional tools you need are free. There is also Azure AppFabric ACS test version available and you can try it out for free. Table of contents Foreword Acknowledgments Introduction Part I Windows Identity Foundation for Everybody 1 Claims-Based Identity 2 Core ASP.NET Programming Part II Windows Identity Foundation for Identity Developers 3 WIF Processing Pipeline in ASP.NET 4 Advanced ASP.NET Programming 5 WIF and WCF 6 WIF and Windows Azure 7 The Road Ahead Index

• Managing Scripts in Oracle SQL Developer

  - by thatjeffsmith

  You backup your databases, right? You backup you home computer – your media collection, tax documents, bank accounts, etc, right? You backup your handy-dandy SQL scripts, right? Ok, now that I’ve got your head nodding, I want to answer a question I get every so often: How can I manage my scripts in SQL Developer? This is an interesting question. First, it assumes that one SHOULD manage their scripts in their IDE. Now, what I think the question generally gets around to is, how can we: Navigate to our scripts Open them Execute them What a good IDE should have is an interface to your existing Version Control System (VCS.) SQL Developer supports out-of-the-box both Subversion and Git. You can also download an extension via check-for-updates to get support for CVS. Now, what I’m about to show you COULD be done without versioning and controlling your scripts – but I want to ask you why you wouldn’t want to do this? So, I’m going to proceed and assume that you do INDEED version your scripts already. Seeing what scripts you’ve already got in your repository This is very straightforward – just open the Team Versions panel. Then connect to your repository. Shows you the files in your source control system. Now, I could ‘preview’ said file right away. If I open the file from here, we get a temp file copy down from the server to the local machine. This is a local temp copy of the controlled script – I can read/execute, but not write to it. And that might be all you need. But, if your script calls other scripts, then you’re going to want to check out the server copy of your stuff down your local SVN working copy directory. That way when your script calls another script – you’re executing the PRODUCTION APPROVED copies of said scripts. And if you do SPOOL or other file I/O stuff, it will work as expected. To get to those said client copies of your scripts… Enter the Files Panel The Files panel is accessible from the View menu. You can get to your files, one of two ways. If you’ve touched the file recently, you can see it under the Recent tree. Otherwise, you can navigate to your local ‘checked out’ copies of your script(s). Open your local copies, see what’s changed, etc. And I can access the change history and see what’s been touched… What changes am I going to ‘push out’ if I commit this back to the server? Most of us work on teams, yes? This panel also gives me a heads up if someone else is making changes to the same file. I can see the ‘incoming’ changes as well. To Sum It Up… If I want to get a script to run: do a full get to your local directory open the script(s) The files panel will tell you if your local copy is out of date from the server and if you have made local changes you’ve forgotten to commit back up to the server and your fellow teammates. Now, if you’re the selfish type and don’t want to share, that’s fine. But you should still be backing up your scripts, and you can still use the Files panel to manage your scripts.

BUT, then in the workplace I've worked at two companies, one, a very well known public facing high traffic website, and another high end Financial Services "Web-Based" hosted solution catering to some very large, very well known companies, which is where I currently Reside and everything's working just fine (KNOCK KNOCK!!). I'm constantly interfacing with EXTREMELY Old technology with some of these financial institutions.. OLD LIKE YOU WOULDN'T BELIEVE.. which leads me to the conclusion that if it works "LEAVE IT", and that maybe there's some value in old technology? at least enough value to overrule a rewrite!? right?? Is there something fundamentally flawed with the underlying technology that VSS uses? I have a feeling that if i said "someone said VSS Sucks" they would beg to differ, most likely give me this look like i dont know -ish, and I'd never gain back their respect and my credibility (well, that'll be hard to blow.. lol), BUT, give me an argument that I can take to someone whose been coding for 30 years, that builds Platforms that leverage current technology (.NET 3.5 / SQL 2008 R2 ), write's their own ORM with scaffolding and is able to provide a quality platform that supports thousands of concurrent users on a multi-tenant hosted solution, and does not agree with any benefits from having Source Control Integrated, and yet uses the Infamous Visual Source Safe. I have extensive experience with TFS up to 2010, and honestly I think it's great when a team (beyond developers) can embrace it. I've worked side by side with someone whose a die hard SVN'r and from a purist standpoint, I see the beauty in it (I need a bit more, out of my SS, but it surely suffices). So, why are such smarties not running away from Visual Source Safe? surely if it was so bad, it would've have been realized by now, and I would not be sitting here with this simple old, Check In, Check Out, Version Resistant, Label Intensive system. But here I am... I would love to drop an argument that would be the end all argument, but if it's a matter of opinion and personal experience, there seems to be too much leeway for keeping VSS. UPDATE: I guess the best case is to have the VSS supporters check other people's experiences and draw from that until we (please no) experience the breaking factor ourselves. Until then, i wont be engaging in a discussion to migrate off of VSS.. UPDATE 11-2012: So i was able to convince everyone at my work place that since MS is sun downing Visual Source Safe it might be time to migrate over to TFS. I was able to convince them and have recently upgraded our team to Visual Studio 2012 and TFS 2012. The migration was fairly painless, had to run analyze.exe which found a bunch of errors (not sure they'll ever affect the project) and then manually run the VSSConverter.exe. Again, painless, except it took 16 hours to migrate 5 years worth of everything.. and now we're on TFS.. much more integrated.. much more cooler.. so all in all, VSS served it's purpose for years without hick-up. There were no horror stories and Visual Source Save as source control worked just fine. so to all the nay sayers (me included). there's nothing wrong with using VSS. i wouldnt start a new project with it, and i would definitely consider migrating to TFS. (it's really not super difficult and a new "wizard" type converter is due out any day now so migrating should be painless). But from my experience, it worked just fine and got the job done.

• JRockit R28/JRockit Mission Control 4.0 is out!

  - by Marcus Hirt

  The next major release of JRockit is finally out! Here are some highlights: Includes the all new JRockit Flight Recorder – supersedes the old JRockit Runtime Analyser. The new flight recorder is inspired by the “black box” in airplanes. It uses a highly efficient recording engine and thread local buffers to capture data about the runtime and the application running in the JVM. It can be configured to always be on, so that whenever anything “interesting” happens, data can be dumped for some time back. Think of it as your own personal profiling time machine. Automatic shortest path calculation in Memleak – no longer any need for running around in circles when trying to find your way back to a thread root from an instance. Memleak can now show class loader related information and split graphs on a per class loader basis. More easily configured JMX agent – default port for both RMI Registry and RMI Server can be configured, and is by default the same, allowing easier configuration of firewalls. Up to 64 GB (was 4GB) compressed references. Per thread allocation profiling in the Management Console. Native Memory Tracking – it is now possible to track native memory allocations with very high resolution. The information can either be accessed using JRCMD, or the dedicated Native Memory Tracking experimental plug-in for the Management Console (alas only available for the upcoming 4.0.1 release). JRockit can now produce heap dumps in HPROF format. Cooperative suspension – JRockit is no longer using system signals for stopping threads, which could lead to hangs if signals were lost or blocked (for example bad NFS shares). Now threads check periodically to see if they are suspended. VPAT/Section 508 compliant JRMC – greatly improved keyboard navigation and screen reader support. See New and Noteworthy for more information. JRockit Mission Control 4.0.0 can be downloaded from here: http://www.oracle.com/technology/software/products/jrockit/index.html <shameless ad> There is even a book to go with JRMC 4.0.0/JRockit R28! http://www.packtpub.com/oracle-jrockit-the-definitive-guide/book/ </shameless ad>

• Control Your Favorite Music Player from Firefox

  - by Asian Angel

  Do you love listening to music while you browse? Now you can access and control your favorite music player directly from Firefox with the FoxyTunes extension. FoxyTunes in Action Once you have installed the extension and restarted Firefox you will see the FoxyTunes Toolbar located in the “Status Bar”. The default media app is Windows Media Player but can be easily changed. Here are the buttons/items available with the default settings: Search, FoxyTunes Main Menu, Show Player, Select Player, Previous Track, Play, Next Track, Mute On/Off, Volume, Play File, Twitty Tunes, Foxy Tunes Search/Explore, Open FoxyTunes Planet, & Toggle Visibility/Drag and drop to move. Note: You can hide or show individual buttons/items using the “FoxyTunes Menus”. Curious about the media players that FoxyTunes works with? Here is a complete listing…that definitely looks terrific! Notice that the currently selected media app is “bold and blue”. For our example we chose Spotify which we have previously covered. Keep in mind that you may or may not need to have your favorite media app open prior to “starting” FoxyTunes up (i.e. Play Button). Here is a good look at the “FoxyTunes Main Menu” and “Controls Sub-Menu”. The “Extras Menu”…if you click on skins you will be taken to the FoxyTunes Skins webpage. Here is a closer look into the “Configurations Menu” and one of the sub-menus. You do not need to look for options in the “Add-ons Manager Window”…everything you need is contained in these menus. If you do not like having FoxyTunes in the “Status Bar” you can easily drag and drop it to another toolbar. You can also condense the appearance of FoxyTunes using the small “triangle buttons” that are located in different spots throughout the “FoxyTunes Toolbar”. With just a click or two you can greatly reduce its’ impact on your UI. Conclusion If you love listening to music while browsing then the FoxyTunes extension will let you take care of everything right from your browser.

• Who should control navigation in an MVVM application?

  - by SonOfPirate

  Example #1: I have a view displayed in my MVVM application (let's use Silverlight for the purposes of the discussion) and I click on a button that should take me to a new page. Example #2: That same view has another button that, when clicked, should open up a details view in a child window (dialog). We know that there will be Command objects exposed by our ViewModel bound to the buttons with methods that respond to the user's click. But, what then? How do we complete the action? Even if we use a so-called NavigationService, what are we telling it? To be more specific, in a traditional View-first model (like URL-based navigation schemes such as on the web or the SL built-in navigation framework) the Command objects would have to know what View to display next. That seems to cross the line when it comes to the separation of concerns promoted by the pattern. On the other hand, if the button wasn't wired to a Command object and behaved like a hyperlink, the navigation rules could be defined in the markup. But do we want the Views to control application flow and isn't navigation just another type of business logic? (I can say yes in some cases and no in others.) To me, the utopian implementation of the MVVM pattern (and I've heard others profess this) would be to have the ViewModel wired in such a way that the application can run headless (i.e. no Views). This provides the most surface area for code-based testing and makes the Views a true skin on the application. And my ViewModel shouldn't care if it displayed in the main window, a floating panel or a child window, should it? According to this apprach, it is up to some other mechanism at runtime to 'bind' what View should be displayed for each ViewModel. But what if we want to share a View with multiple ViewModels or vice versa? So given the need to manage the View-ViewModel relationship so we know what to display when along with the need to navigate between views, including displaying child windows / dialogs, how do we truly accomplish this in the MVVM pattern?

  socat - exec:'bash -li',pty,stderr,ctty - bash: no job control in this shell What options should I use to get fully fledged shell as I get with ssh/sshd? I want be able to connect the shell to everything socat can handle (socks5, udp, openssl), but also to have a nice shell which correctly interprets all keys, various Ctrl+C/Ctrl+Z and jobs control. Update: Found "setsid" socat option. It fixes "no job control". Now trying to fix Ctrl+D.

• how do you document your development process?

  - by David

  My current state is a mixture of spreadsheets, wikis, documents, and dated folders for my input/configuration and output files and bzr version control for code. I am relatively new to programming that requires this level of documentation, and I would like to find a better, more coherent approach. update (for clarity): My inputs are data used to generate configuration files with parameter values and my outputs are analyses of model predictions. I would really like to have an approach that allows me to associate particular configuration(s) with particular outputs, so that I can ask questions of my documentation such as "what causes over/under estimates?" or "what causes error 'X'"?

• How should I manage "reverting" a branch done with bookmarks in mercurial?

  - by Earlz

  I have an open source project on bitbucket. Recently, I've been working on an experimental branch which I (for whatever reason) didn't make an actual branch for. Instead what I did was use bookmarks. So I made two bookmarks at the same revision test --the new code I worked on that should now be abandoned(due to an experiment failure) main -- the stable old code that works I worked in test. I also pushed from test to my server, which ended up switching the tip tag to the new unstable code, when I really would've rather it stayed at main. I "switched" back to the main bookmark by doing a hg update main and then committing an insignificant change. So, I pushed this with hg push -f and now my source control is "correct" on the server. I know that there should be a cleaner way to "switch" branches. What should I do in the future for this kind of operation?
