  • 11 ADF Mobile Apps in 30 Hours

    - by Shay Shmeltzer
    The Oracle ADF Mobile team took part in a special "hackathon" this weekend, where 11 teams of new college hires who joined Oracle lately spent 30 hours building enterprise mobile applications leveraging ADF Mobile. One important thing to note - none of the participants worked with Oracle ADF Mobile before! In fact 90% of them didn't develop with ADF previously. All they had is a 2 hour training session before the event - and that's all they needed. From that point on they were able to build great cross device mobile applications. So what did they build? Here are some examples: A mileage expense tracking system: An ad campaign analysis system An expense report entry system Bug tracking system with data analysis: Carpooling social system: College Hiring system with CV scanning: Shipment management system for Farmers: Project time entry system: For sale post-it system (with item location): Conference event experience system with conference map and twitter feed integration: It was great to see how fast developers were able to learn and leverage ADF Mobile - and how creative the teams were. Here they are in action: So how about you? What would you build next? What would be your first ADF Mobile application? Start today!

  • C# return variables

    - by pb01
    In a debate regarding return variables, some members of the team prefer a method to return the result directly to the caller, whereas others prefer to declare a return variable that is then returned to the caller (see code examples below) The argument for the latter is that it allows a developer that is debugging the code to find the return value of the method before it returns to the caller thereby making the code easier to understand: This is especially true where method calls are daisy-chained. Are there any guidelines as to which is the most efficient and/or are there any other reasons why we should adopt one style over another? Thanks private bool Is2(int a) { return a == 2; } private bool Is3(int a) { var result = a == 3; return result; }

  • Issue with user having a gmail account and Google Apps account using same email/username

    - by Joshua
    Greetings! We have a user in our organization that had been using her email address at our domain at her username for gmail.com We recently moved our folks on to Google Apps, and have just moved our email server over to Google (IMAP/SMTP). I'm having all kinds of trouble only with this user's account with her sending and receiving email via the new Google mail server and wondering if it's because of her existing Gmail account. So her email address with us is [email protected], which is her login/user id with us on our Google Apps site. She still has her gmail identity tied to that same [email protected]. She's ok with deleting her old Gmail account...if I do so however will it goof things up for her going forward with us on the Google Apps site? Will she not be able to receive email? Thanks! Joshua

  • Menubar hidden in all KDE apps

    - by Francesco Feltrinelli
    I am using Kubuntu 10.10 with Plasma-Netbook on my netbook. Somehow I messed up with window's settings and now the menubar (the one on top of the window, just below the titlebar, which has the File button, Edit, Settings, Help, ...) is hidden from all my KDE applications. Here you can see how the menubar should be correctly displayed: Here you can see how it is actually displayed on my netbook: I don't remember what I did to hide the menubar, I clicked somewhere in the context menu which shows right-clicking on window title, but I cannot find that setting anymore. Can you please help me? Thank you very much.

  • HTML5 mobile game development vs. native game apps

    - by Vic Szpilman
    What is the current state of game engines, frameworks, libraries and conversions related to the HTML5 set of technologies (including CSS3 and JavaScript libraries such as RaphaelJS, Impact, gameQuery); and how does the best of that compare with developing a native app (especially for iOS and Android)? Especially in terms of performance, visuals and getting that "native feel". Thoughts on solutions such as Appcelerator and Corona SDK are also appreciated. In regards to Unity3D, is it possible to develop in it and still have the game be playable on a browser (such as current releases of Chrome or Firefox, at least) without any dependencies or having the user install anything (no unity web player). What I'm looking for is how to develop in web standards as to reach the maximum number of platforms (including outside mobile) while still retaining a native experience for mobile without having to implement the game anew for iOS and Android.

  • .NET 4: &ldquo;Slim&rdquo;-style performance boost!

    - by Vitus
    RTM version of .NET 4 and Visual Studio 2010 is available, and now we can do some test with it. Parallel Extensions is one of the most valuable part of .NET 4.0. It’s a set of good tools for easily consuming multicore hardware power. And it also contains some “upgraded” sync primitives – Slim-version. For example, it include updated variant of widely known ManualResetEvent. For people, who don’t know about it: you can sync concurrency execution of some pieces of code with this sync primitive. Instance of ManualResetEvent can be in 2 states: signaled and non-signaled. Transition between it possible by Set() and Reset() methods call. Some shortly explanation: Thread 1 Thread 2 Time mre.Reset(); mre.WaitOne(); //code execution 0 //wating //code execution 1 //wating //code execution 2 //wating //code execution 3 //wating mre.Set(); 4 //code execution //… 5 Upgraded version of this primitive is ManualResetEventSlim. The idea in decreasing performance cost in case, when only 1 thread use it. Main concept in the “hybrid sync schema”, which can be done as following:   internal sealed class SimpleHybridLock : IDisposable { private Int32 m_waiters = 0; private AutoResetEvent m_waiterLock = new AutoResetEvent(false);   public void Enter() { if (Interlocked.Increment(ref m_waiters) == 1) return; m_waiterLock.WaitOne(); }   public void Leave() { if (Interlocked.Decrement(ref m_waiters) == 0) return; m_waiterLock.Set(); }   public void Dispose() { m_waiterLock.Dispose(); } } It’s a sample from Jeffry Richter’s book “CLR via C#”, 3rd edition. Primitive SimpleHybridLock have two public methods: Enter() and Leave(). You can put your concurrency-critical code between calls of these methods, and it would executed in only one thread at the moment. Code is really simple: first thread, called Enter(), increase counter. Second thread also increase counter, and suspend while m_waiterLock is not signaled. So, if we don’t have concurrent access to our lock, “heavy” methods WaitOne() and Set() will not called. It’s can give some performance bonus. ManualResetEvent use the similar idea. Of course, it have more “smart” technics inside, like a checking of recursive calls, and so on. I want to know a real difference between classic ManualResetEvent realization, and new –Slim. I wrote a simple “benchmark”: class Program { static void Main(string[] args) { ManualResetEventSlim mres = new ManualResetEventSlim(false); ManualResetEventSlim mres2 = new ManualResetEventSlim(false);   ManualResetEvent mre = new ManualResetEvent(false);   long total = 0; int COUNT = 50;   for (int i = 0; i < COUNT; i++) { mres2.Reset(); Stopwatch sw = Stopwatch.StartNew();   ThreadPool.QueueUserWorkItem((obj) => { //Method(mres, true); Method2(mre, true); mres2.Set(); }); //Method(mres, false); Method2(mre, false);   mres2.Wait(); sw.Stop();   Console.WriteLine("Pass {0}: {1} ms", i, sw.ElapsedMilliseconds); total += sw.ElapsedMilliseconds; }   Console.WriteLine(); Console.WriteLine("==============================="); Console.WriteLine("Done in average=" + total / (double)COUNT); Console.ReadLine(); }   private static void Method(ManualResetEventSlim mre, bool value) { for (int i = 0; i < 9000000; i++) { if (value) { mre.Set(); } else { mre.Reset(); } } }   private static void Method2(ManualResetEvent mre, bool value) { for (int i = 0; i < 9000000; i++) { if (value) { mre.Set(); } else { mre.Reset(); } } } } I use 2 concurrent thread (the main thread and one from thread pool) for setting and resetting ManualResetEvents, and try to run test COUNT times, and calculate average execution time. Here is the results (I get it on my dual core notebook with T7250 CPU and Windows 7 x64): ManualResetEvent ManualResetEventSlim Difference is obvious and serious – in 10 times! So, I think preferable way is using ManualResetEventSlim, because not always on calling Set() and Reset() will be called “heavy” methods for working with Windows kernel-mode objects. It’s a small and nice improvement! ;)

  • Customizing Google Sites look and feel

    - by David Parunakian
    I find the site layout and theming capabilities in Google Sites (found in the Manage Site screen) very limited; for instance, I do not seem to be able to place the horizontal navigation buttons directly to the right of the logo and to customize their style, as well as to use the standard trick of making a horizontally stretchable background image of a box with rounded corners by splitting it into three parts and replicating the middle one, etc. Am I missing something? Are there any advanced settings available? Thanks.

  • Sharing Windows Store apps between accounts

    - by Klas Mellbourn
    In Windows 8 it seems natural to me that each person in a family has their own Microsoft Account with which they log in. If you pay for an app on the Windows Store, you can install that same app on several computers using the same Microsoft Account. Good. However, if several persons, in this case my children, each have their own account on the same computer, they do not get access to apps bought on a sibling's account, even if the app has been installed on the same computer. Bad. (Compare this to iOS where you are allowed have several iPhones with different iCloud-connected accounts but all using the same iTunes App Store account, which is perfect for a family where all can then use the same app which was bought just once) Is there any way to share apps between Microsoft Accounts (e.g. members of the same family)? Alternatively, is there a way to run apps that are installed on a computer when you are logged in with a Microsoft Account different than the one used when installing the app?

  • How to Hibernate from .NET Apps and How to enable Hibernate in Windows XP

    The usage of Computer desktop or laptop is increased all around the world phenomenally. This link gives you the picture on how power consumption is for various devices we use daily. to reduce the power consumption Hibernate is one of the best way provided by default in Windows Vista or Windows 7. Hibernate feature enables you to close the machine without closing your applications, that means the applications will be restored as they were once we restart the machine. Hibernate feature is not enabled in Windows XP by default. I’ve seen many people that they run (do not switch off) the machines months and months as they do not want to close the windows or applications running in Windows XP. below are the steps to enable Hibernate in Windows XP. Right click on Desktop. Click on properties. Go to screen save tab. Click on power button Select Hibernate tab Check the checkbox “Enabled Hibernate” Apply the settings. Now when you try to shutdown, “Shut down windows” dialog shows “Hibernate” options. Now you can safely close the machine without closing your applications or windows as they will be restored once you on the machine. </SPAN? Some time you might want to provide this future programmatically for the applications you develop for windows. Generally you might want to provide this option in windows applications where process needs huge time. Download managers are the one of the best example. below is the code to do a Hibernate from the .NET code. using System.Windows.Forms;namespace CodeKicks.WinApp.Machine{ public static class MyMachineHelper { public static void DoHibernate() { //Application.SetSuspendState(PowerState.Suspend, true, false); Application.SetSuspendState(PowerState.Hibernate, true, false); } }} span.fullpost {display:none;}

  • Auto-tiling with Yoshi's Island style tiles

    - by Boreal
    I'm creating a 2D platformer and I'd like to implement an auto-tiling system. Normally, this wouldn't be particularly difficult. However, I'd like to have tiles like in Yoshi's Island, where the graphics extend past the actual collidable tile's boundaries. Consider this image: Although the eggs and the Piranha Plant are clearly resting on the ground, the flower tiles continue behind them, out of the collidable tile. I know that it would be simple to do by hand, but extremely time consuming. Using an auto-tiling algorithm would save me a lot of time and boredom, but I'm not sure where to start.

  • Actions and Controllers managing strategy in MVC apps

    - by singleton
    Can anyone name any usefull strategy/architectural pattern for allocating actions between different controllers when using MVC pattern for developing web application? I am now developing web app using asp.net Mvc3 framework and still can't figure out how to manage actions and controllers. One approach is to create single action controller for each url, but it's not the best choice since to much controllers have to be created. Should I list all available urls that are supported by me web app, devide them into groups and create separate controller for each group or act in any different manner? It seems like I will become face to face with some kind of mess with no consistent approach in managing actions and controllers.

The background is, lets say 10, 000 users hit the player "Alex Rodriguez", the application have to calculate 10, 000 the A-Rod stats by years intead of just read it from some where is temporal saved. Here I go: What is the best method for caching this type of data? Do I have to used the same database, and some temporal values on the same database, or create a Web Service for that? What reading about web caching so you recommend?

  • Portable Class Library even better in .NET 4.5

    - by nmarun
    Visual Studio 2012 makes Cross-Platform development even easier. It comes with a feature called Portable Class Library (PCL). This feature was available in Visual Studio 2010 as well, but it required an additional install as against being out-of-the-box for 2012. It’s also worth noting that PCL is available only for Pro and above versions of 2012. So it’s not available with the Express edition of Visual Studio 2012. Let’s get started. In Visual Studio 2012 you can see a template called Portable Class...(read more)

  • Creating a retro-style palette swapping effect in OpenGL

    - by Zack The Human
    I'm working on a Megaman-like game where I need to change the color of certain pixels at runtime. For reference: in Megaman when you change your selected weapon then main character's palette changes to reflect the selected weapon. Not all of the sprite's colors change, only certain ones do. This kind of effect was common and quite easy to do on the NES since the programmer had access to the palette and the logical mapping between pixels and palette indices. On modern hardware, though, this is a bit more challenging because the concept of palettes is not the same. All of my textures are 32-bit and do not use palettes. There are two ways I know of to achieve the effect I want, but I'm curious if there are better ways to achieve this effect easily. The two options I know of are: Use a shader and write some GLSL to perform the "palette swapping" behavior. If shaders are not available (say, because the graphics card doesn't support them) then it is possible to clone the "original" textures and generate different versions with the color changes pre-applied. Ideally I would like to use a shader since it seems straightforward and requires little additional work opposed to the duplicated-texture method. I worry that duplicating textures just to change a color in them is wasting VRAM -- should I not worry about that?

  • Organising levels / rooms in a MUD-style text based world

    - by Polynomial
    I'm thinking of writing a small text-based adventure game, but I'm not particularly sure how I should design the world from a technical standpoint. My first thought is to do it in XML, designed something like the following. Apologies for the huge pile of XML, but I felt it important to fully explain what I'm doing. <level> <start> <!-- start in kitchen with empty inventory --> <room>Kitchen</room> <inventory></inventory> </start> <rooms> <room> <name>Kitchen</name> <description>A small kitchen that looks like it hasn't been used in a while. It has a table in the middle, and there are some cupboards.

Interaction with people and enemies as well as death and completion are necessary additions. Since the XML is quite difficult to work with, I'd probably create some sort of world editor. I'd like to know if this method has any downfalls, and if there's a "better" or more standard way of doing it.

  • How To Enable Aero Glass-Style Transparency in Windows 8

  • Apple iOS Apps and caching at the edge proxy

    - by Matthew Iselin
    Our network contains a growing number of iOS devices, all of which with very similar configurations. All Internet access is via a transparent proxy. We've found that iOS updates and some free apps cache fine on the proxy, but any paid apps fail to cache properly (as they seem to be encrypted to the Apple ID (?)). I'm just wondering if there's any way forward with this where we could cache the paid apps so that they are purchased n times, but downloaded from the proxy cache instead of from the Internet each time. Bandwidth caps aside, the download direct from the Internet slows everything down for everyone, regardless of fairness queueing and related 'fixes'. I know this is quite unlikely, but I figured there's nothing to lose and everything to gain before I look into other solutions (eg, QoS).
