• What almost unknown programming language of 21st century a programmer should be introduced to?

  - by bigown

  Which languages almost nobody talks about but has some interesting features or concepts? It must satisfy the following 2 criteria: It must have been created in 2000 or later. Ex.: REBOL, Squeak, Oberon, etc. are out. It can't have some fame among programmers. Ex.: Groovy, C#, Scala, Go, Clojure, D, etc are out. The language doesn't need be good or totally implemented. License or platform doesn't matter. The language needs to be new and interesting. I posted a good example of language I wanna know. If you wish TIOBE can be used as reference to measure "fame", but don't cling on it.

• Windows 8 Location Services

  - by ryanabr

  I spent the afternoon with the Geolocator object in the WinRT and Widows 8 platform. I have also been working with doing Windows Phone 7 development, and first had to wrap my head around the fact that while similar, it is not the same as the GeoCoordinateWatcher that environment. I found a nice example here http://code.msdn.microsoft.com/windowsapps/Geolocation-2483de66 But the behavior of my app wasn’t the same. Once you ensure that location services is enabled by following these instructions: http://msdn.microsoft.com/en-us/library/windows/desktop/hh768219.aspx Location Services was still disabled. From everything I read, it sounded like the first time you try to use the Geolocator object, the user would be prompted to allow to “Access to your location”. After nosing around I found the issue. You need to add the location service as a Capability in the Package.appxmanifest file: After checking the box, I was prompted to allow access to location services as expected the first time I needed to use it.

• Is it possible to work with a dedicated server in XNA?

  - by Jake

  Hi I want to release my XNA game to the XBOX platform, but I'm worried about the networking limitations. Basically, I want to have a dedicated (authoritative) server, but it sounds like that is not possible. Which is why I'm wondering about: Using port 80 web calls to php-driven database Using an xbox as a master-server (is that possible?) I like the sound of #1, because I could write my own application to run on the xbox, and I would assume other users could connect to it similar to the p2p architecture. Anyone able to expand on theory #2 above? or #1 as worst-case scenario?

• Meet Windows Azure on June 7th

  - by ScottGu

  As many of you might know, I’ve spent much of my time the past 12 months working on Windows Azure – which is Microsoft’s Cloud Computing Platform (I also continue to run the teams that build ASP.NET, the server framework libraries of .NET, and a few other products too). I will be doing a keynote in San Francisco this Thursday, June 7th at 1pm PDT.  The event will be streamed live, and I hope you’ll be able to join us as we walkthrough some of the exciting work we’ve been doing – and how you’ll be able to take advantage of it as developers.

• Server costs and back loading for mobile devices

  - by user23844

  A company approached me to design an MMO for the mobile platform and I have the perfect idea for them. My question is how much would a server for a FTP game that has both a PVE element and PVP cost? Also do you think that it would be better or is it even possible to back load the data onto the phones (trying to come up with some interesting way to back up the data in case of emergency). I don't want the game to be totally online reliant (I want to appeal to not only phone users but also iPod touch users) and for there to be an offline mode. If you can't tell this is my first game besides simple projects I've done on the side. Any help would be greatly appreciated.

• Audio libraries for PC indie games [closed]

  - by bluescrn

  Possible Duplicate: Cross-Platform Audio API Suggestions What options are out there these days for audio playback/mixing in C++? Primarily for Windows, but portability (particularly to Mac and iOS) would be desirable. For a small indie game, potentially commercial, though - so I'm looking for something free/low-cost. My requirements are fairly basic - I don't need 3D sound, or many-channels - simple stereo is fine. Just need to be able to mix sound effects and a music stream, maybe decoding one or more compressed audio formats (.ogg/.mp3 etc), with all the basic controls over looping, pitch, volume, etc. Is OpenAL more-or-less the standard choice, or are there other good options out there?

  Past my day job, I also have the privilege of being Vice President and Member of the Board of the OpenWonderland Foundation (Formerly Project Wonderland for ex-Sun folks). It's great to see the progress Wonderland is making as the platform-of-choice for open source collaborative 3-D virtual worlds built in Java. The upcoming and first european IE Summit in Madrid will show a number of projects and innovations for virtual and game-based learning. I also dropped Ultan a note after learning about the Gamification of Oracle Apps to see if collaborating with kids and schools is an area we can work together on to improve kids engagement and learning experiences online.

• Chrome Mobile: The Mobile Web Developers Toolkit (Part 2)

  Chrome Mobile: The Mobile Web Developers Toolkit (Part 2) Building for mobile web requires a different mindset than desktop web development, and a different set of tools. The tools we're used to using often aren't available or would take up too much screen real estate. And going back to the dark ages of tweak/save/deploy/test/repeat isn't exactly optimal, so what can we do? Thankfully there are a number of great options - from remote debugging to emulation, mobile browsers are offering more and more tools to make our lives easier. We'll take a look at a couple of tools that you can use today to make cross platform mobile web development easier and then peer into the crystal ball to see what tools may bring in the future. Join us for Part 2 - as we take a look at a some of the many tools to make testing the mobile web easier. From: GoogleDevelopers Views: 0 0 ratings Time: 01:00:00 More in Science & Technology

• Viewing the NetBeans Central Registry (Part 2)

  - by Geertjan

  Jens Hofschröer, who has one of the very best NetBeans Platform blogs (if you more or less understand German), and who wrote, sometime ago, the initial version of the Import Statement Organizer, as well as being the main developer of a great gear design & manufacturing tool on the NetBeans Platform in Aachen, commented on my recent blog entry "Viewing the NetBeans Central Registry", where the root Node of the Central Registry is shown in a BeanTreeView, with the words: "I wrapped that Node in a FilterNode to provide the 'position' attribute and the 'file extension'. All Children are wrapped too. Then I used an OutlineView to show these two properties. Great tool to find wrong layer entries." I asked him for the code he describes above and he sent it to me. He discussed it here in his blog, while all the code involved can be read below. The result is as follows, where you can see that the OutlineView shows information that my simple implementation (via a BeanTreeView) kept hidden: And so here is the definition of the Node. class LayerPropertiesNode extends FilterNode { public LayerPropertiesNode(Node node) { super(node, isFolder(node) ? Children.create(new LayerPropertiesFactory(node), true) : Children.LEAF); } private static boolean isFolder(Node node) { return null != node.getLookup().lookup(DataFolder.class); } @Override public String getDisplayName() { return getLookup().lookup(FileObject.class).getName(); } @Override public Image getIcon(int type) { FileObject fo = getLookup().lookup(FileObject.class); try { DataObject data = DataObject.find(fo); return data.getNodeDelegate().getIcon(type); } catch (DataObjectNotFoundException ex) { Exceptions.printStackTrace(ex); } return super.getIcon(type); } @Override public Image getOpenedIcon(int type) { return getIcon(type); } @Override public PropertySet[] getPropertySets() { Set set = Sheet.createPropertiesSet(); set.put(new PropertySupport.ReadOnly<Integer>( "position", Integer.class, "Position", null) { @Override public Integer getValue() throws IllegalAccessException, InvocationTargetException { FileObject fileEntry = getLookup().lookup(FileObject.class); Integer posValue = (Integer) fileEntry.getAttribute("position"); return posValue != null ? posValue : Integer.valueOf(0); } }); set.put(new PropertySupport.ReadOnly<String>( "ext", String.class, "Extension", null) { @Override public String getValue() throws IllegalAccessException, InvocationTargetException { FileObject fileEntry = getLookup().lookup(FileObject.class); return fileEntry.getExt(); } }); PropertySet[] original = super.getPropertySets(); PropertySet[] withLayer = new PropertySet[original.length + 1]; System.arraycopy(original, 0, withLayer, 0, original.length); withLayer[withLayer.length - 1] = set; return withLayer; } private static class LayerPropertiesFactory extends ChildFactory<FileObject> { private final Node context; public LayerPropertiesFactory(Node context) { this.context = context; } @Override protected boolean createKeys(List<FileObject> list) { FileObject folder = context.getLookup().lookup(FileObject.class); FileObject[] children = folder.getChildren(); List<FileObject> ordered = FileUtil.getOrder(Arrays.asList(children), false); list.addAll(ordered); return true; } @Override protected Node createNodeForKey(FileObject key) { AbstractNode node = new AbstractNode(org.openide.nodes.Children.LEAF, key.isFolder() ? Lookups.fixed(key, DataFolder.findFolder(key)) : Lookups.singleton(key)); return new LayerPropertiesNode(node); } } } Then here is the definition of the Action, which pops up a JPanel, displaying an OutlineView: @ActionID(category = "Tools", id = "de.nigjo.nb.layerview.LayerViewAction") @ActionRegistration(displayName = "#CTL_LayerViewAction") @ActionReferences({ @ActionReference(path = "Menu/Tools", position = 1450, separatorBefore = 1425) }) @Messages("CTL_LayerViewAction=Display XML Layer") public final class LayerViewAction implements ActionListener { @Override public void actionPerformed(ActionEvent e) { try { Node node = DataObject.find(FileUtil.getConfigRoot()).getNodeDelegate(); node = new LayerPropertiesNode(node); node = new FilterNode(node) { @Override public Component getCustomizer() { LayerView view = new LayerView(); view.getExplorerManager().setRootContext(this); return view; } @Override public boolean hasCustomizer() { return true; } }; NodeOperation.getDefault().customize(node); } catch (DataObjectNotFoundException ex) { Exceptions.printStackTrace(ex); } } private static class LayerView extends JPanel implements ExplorerManager.Provider { private final ExplorerManager em; public LayerView() { super(new BorderLayout()); em = new ExplorerManager(); OutlineView view = new OutlineView("entry"); view.addPropertyColumn("position", "Position"); view.addPropertyColumn("ext", "Extension"); add(view); } @Override public ExplorerManager getExplorerManager() { return em; } } }

• Invoking JavaScript from Java

  - by Geertjan

  Here's an Action class defined in Java. The Action class executes a script via the JavaFX WebEngine: @NbBundle.Messages("CTL_AddBananasAction=Add Banana") private class AddBananasAction extends AbstractAction { public AddBananasAction() { super(Bundle.CTL_AddBananasAction()); } @Override public void actionPerformed(ActionEvent e) { Platform.runLater(new Runnable() { @Override public void run() { webengine.executeScript("addBanana(' " + newBanana + " ') "); } }); } }How does the 'executescript' call know where to find the JavaScript file? Well, earlier in the code, the WebEngine loaded an HTML file, where the JavaScript file was registered: WebView view = new WebView(); view.setMinSize(widthDouble, heightDouble); view.setPrefSize(widthDouble, heightDouble); webengine = view.getEngine(); URL url = getClass().getResource("home.html"); webengine.load(url.toExternalForm()); Finally, here's a skeleton 'addBanana' method, which is invoked via the Action class shown above: function addBanana(user){ statustext.text(user); } By the way, if you have your JavaScript and CSS embedded within your HTML file, the code navigator combines all three into the same window, which is kind of cool:

• Will Java be dead if the split into free/premium JVM happens?

  - by cringe

  According to http://www.theregister.co.uk/2010/11/06/oracle_dueling_jvms/ there is a possibility that Oracle really will kill Java split Java into Free and Premium JVMs. My Questions Do you think this will happen? Will this kill Java at the end? If you answer both questions with Yes, what are you doing about it? Which language would you choose, and which platform will you use? .NET/Mono? Plain compiled languages like Golang? Ruby? And if you answer No, why do you think Oracle will not harm Java and the community?

• How to run WordPress and Java web app running on Tomcat on the same server?

  - by Chantz

  I have to run a WordPress site served via Apache2 & Java-based webapp using Tomcat on the same server. When users come to example.com or example.com/public-pages they need to served from WordPress but when they come to example.com/private-pages they need to be served from the Tomcat. I have asked this question on serverfault where they suggested using different port, different IP & sub-domain. I want to go for different port solution since it will mean I need to buy only one SSL certificate. I tried doing the reverse proxy method by having the following in my default-ssl.conf <VirtualHost _default_:443> ServerAdmin webmaster@localhost ServerName localhost:443 DocumentRoot /var/www <Directory /var/www> #For Wordpress Options FollowSymLinks AllowOverride All </Directory> <Proxy *> Order deny,allow Allow from all </Proxy> ProxyRequests Off ProxyPass /private-pages ajp://localhost:8009/ ProxyPassReverse /private-pages ajp://localhost:8009/ SSLEngine on SSLProxyEngine On SSLCertificateFile /etc/apache2/ssl/apache.crt SSLCertificateKeyFile /etc/apache2/ssl/apache.key </VirtualHost> As you have noticed I am using mod_proxy_ajp in Apache2 for this. And that my Tomcat is listening to port 8009 and then serving content. So now when I go to example.com/private-pages I am seeing the content from my Tomcat. But 2 issues are happening. All my static resources are getting 404-ed, so none of my images, CSS, js are getting loaded. I see that the browser is requesting for the resources using URL example.com/css/* This will clearly not work because it translates to example.com:80/css/* instead of example.com:8009/css/* & there are no such resources in the WordPress directory. If I go to example.com/private-pages/abcd I am somehow kicked to the WordPress site (which obviously displays a 404 page). I can understand why #1 is happening but have no clue why the #2 is happening. Regardless, if there is another clean solution for resolving this, I would appreciate y'alls help.

• Does language endorsement by different platforms (Android, iOS) hurt app development?

  - by MSe

  Developing iOS or OSX based applications typically requires knowledge of Objective C, since XCode is highly tailored to this language. Android, on the other hand, has chosen Java as it's preferred language for app development. Now, I know other programming languages can be used to develop applications on either platform, but lets be honest, it's a lot easier (and encouraged) to develop apps using these "native languages." As a new app developer, it seems like it would be much easier if there was a common language and development environment for developing applications on all the major platforms. This thought is probably too idealistic for a programming discussion, and I wouldn't be surprised if the SE vultures flew in to close this topic. But, here's my question. Do you think that language endorsement creates unreasonable barriers to entry for new programmers, or do you think it's beneficial in some way (if so, why) for these platforms to use completely different development environments and languages for app development?

• Changing hosts but keep old emails [closed]

  Possible Duplicate: Change host / keep emails OK here's the situation...I'm trying to transfer my domain and email address to a new hosting service and I would like to start using Google's domain apps for my email, etc. My email address is currently on a WebMail type platform and when I move my domain and start using Google domain apps I would also like to keep the old emails and have them imported the the email address on Google. Note: The email address will be the same on both hosts. For example [email protected]. So its keeping the same address between two different systems. I've been Googling how to do this for awhile and all the migrate options that come up don't appear in the the Google inbox setting or domain apps config settings. Any help is greatly appreciated.

• Create .exe and .msi Installers for your JavaFX Apps

  - by mikew_co

  Well I wanted to figure out how the new JavaFX native packaging worked, so with a little work, I have written up my findings. Create a Windows Native Installer and EXE with JavaFX and NetBeans 7.2All the information is in the articles I have linked to at the end of the page. However, I hopefully have pulled together all the key facts in one place. In addition, I tried to document all the problems I ran into in the troubleshooting section. So what is the end result?  With everything installed, building an application in NetBeans creates an EXE installer, an MSI installer, and an EXE file to execute your application. Really slick professional stuff. This is a great addition to the whole Java platform.

• What is the difference between being an IT in investment bank and a professional IT company?

  - by deepsky

  Suppose there are two positions: IT in investment bank: developer for the infrastructure or the platform a famous IT company: embedded developer, linux As far as I understand, since in the investment bank not everyone will have the chance to work for the core trading system, most people just do the same job as they do in a normal IT company. And some of the tasks can even be outsourced. But in a professional IT company, you will have more chance to practice your coding skill and enhance your professional knowledge. So there are many choices when you want to change your job while the IT in invest bank not. Is this correct?

• Receive anonymous users' input by web upload form or email. Any online service for that?

  - by sja

  Are you aware of any online service or online "platform" allowing users, not previously registered, to upload pairs of picture+comment to a database? It would be a collaborative database of picture+comment pairs. I'm not going wiki or googlegroup, picasa or such because I'd like the user to have the least to do to participate, that is e.g.: take a picture with his phone and email it to an email to an email address. Or go to a web page with an upload form, type in a description, hit OK and that's it. And the goal is also that it be as hassle-less to put up as possible. Yeah I know, it can't programme itself to my requirements :) by I'm suspecting there's a tool or tool combination going a decent way through my needs. Thanks for any info/advice! SJA (NB the final goal is a kind of crowd-sourced census of specific urban items. If you have comment about the potential for spam-overload of my idea, other than "you're doomed", you're welcome!)
