• Which is better? Native App or hybrid App?

  - by Prabakaran

  I want to develop a simple App for iOS, Android and windows phone. I just wondered that a simple HTML5, JS and CSS combination can work in all of these platforms. I want to know which one will be efficient? No problem with time and coding. But if i can achieve everything with HTML5-JS itself, i will chose Hybrid development. I want to know the major difference between the Native and Hybrid Development with example(I know that the main difference is HTML5-JS supports cross platform). Note : I am not making a game app.

• Logitech Wireless Keyboard & mouse not working aftesr upgrade to 12.04?

  - by deerjay99

  I upgraded my Dell Dimension 9200C to 12.04 Precise Pangolin with no issues, I ran it fine for a night but when I went back in a couple days later my Logitech Wireless Keyboard K350 and M510 mouse weren't active when booted. I can boot into an older version from the main the boot screen the mouse and keyboard work, but the network stack is gone. It says the networking manager on this version is not compatible. I'm scratching my head, it isn't the mouse and keyboard, they work fine on my dual boot, and they load fine in Knoppix. They did work fine on 12.04 for 1 night. Open to suggestions before I re-install completely.

• What is the best way of testing Ubuntu?

  - by Jay

  I'm a little confused as to whether I should install Ubuntu on its own partition on my hard drive, use VirtualBox or another virtualization package to install it, or use Wubi to install it directly on top of my current OS (Win 7). I definitely want to learn and use Ubuntu, so this is not just for playing around with it. Also, if I choose to partition, should I partition the hard drive myself or should I let the Ubuntu installation menu do it for me? I understand that I am going to need a main partition, for Ubuntu's core components, and also a swap partition. Then there is the option to add a partition for "home"- I don't understand what combination of these partitioning options I should choose, or whether it is better to partition in Windows before I install Ubuntu or just partition my hard drive when I install Ubuntu itself

• Instantiating Interfaces in C#?

  - by RealityDysfunction

  I am reading/learning about interfaces in C# at the moment, and thus far I managed to understand how it differs from an abstract class. In the book I am reading the author explains that interfaces are the ultimate abstract class and that it simply sets the standard of certain methods the inheriting class will have, but then provides the following example... static void Main(string[] args) { ... Circle c = new Circle("Lisa"); IPointy itPt = null; try { itPt = (IPointy)c; Console.WriteLine.(itPt.Points); } catch (InvalidCastException e) { Console.WriteLine(e.Message); } ... } The line that absolutely throws me off is the "IPointy itfPt=null;" did he just declare an interface??? I thought interfaces are abstract and can only be inherited? What kind of sorcery is going on here? Thanks for any help, I

• Client Side Prediction

  - by user13842

  I have a question regarding Client Side prediction. Ive tried to search topics about my specific problem but couldn't find anything which really answered my problem. Most tutorials and explanations assume that the Client sends messages like "Move my player up by 1 Position", but what if i send messages like "Set my player's velocity to x"? Since it's hard to explain with text, i made a graphic explaining my problem. The main problem is, that the player sets his own velocity, due to Client Side Prediction, earlier than the Server. So if 2 different velocities overlap, the Server would get out of sync. How can i tackle that problem? Thanks a lot. Graphic: http://img27.imageshack.us/img27/6083/clientpred.png (Ignore the 5.5cm)

• How to get several frequency ranges at the same time in fmod?

  - by Rootosaurus

  After reading documentation and tutorials about fmod I still have a question about frequency ranges. I've found how to get a frequency range using low and high pass DSP at the same time on the main channel, but I can't find how to get several ranges at the same time. For example I want, for a specific phase of my game, to hear range 400 to 600Hz and 1000 to 2000hz of the same sound. I tried to create a channel by range, but it doesn't seem to work (or maybe I do something wrong). How can I do that ? Thank you

• Collision Detection within Player/Enemy Class

  - by user1264811

  I'm making a 2D platform game. Right now I'm just working on making a very generic Player class. I'm wondering if it would be more efficient/better practice to have an ActionListener within the Player class to detect collisions with Enemy objects (also have an ActionListener) or to handle all the collisions in the main world. Furthermore, I'm thinking ahead about how I will handle collisions with the platforms themselves. I've looked into the double boolean arrays to see which tiles players can go to and which they can't. I don't understand how to use this class and the player class at the same time. Thank you.

• xUnit global setup / teardown [migrated]

  - by Codism

  I need to run some code before any test is executed and also some code after all tests are done. I thought there must be some attributes or marker interface to indicate the global initialization and termination code but couldn't find them. Alternatively, if I can invoke xUnit programmatically, I can also achieve what I want to do by the following code: ... Main(string[] args) { try { MyGlobalSetup(); RunAllTests(); // What goes into this method? } finally { MyGlobalTeardown(); } } Can anyone provide me some hint about how to declaratively or programmally run some global setup/teardown code? Thanks

• Site returning 404 header to google, not sure why

  - by Damon

  A Drupal site that works fine for regular users returns a 404 not found error when I try to use the W3C validator on it; it is also not being indexed by google at all (which is the main issue but I suspect there is a connection). It is a https:// site with .htaccess rule to redirect any http:// request to the https://. I had had it running in google webmaster tools and thought it was fine, but it turns out I had not added the https domain. After adding the https domain it's also returning the header as HTTP/1.1 404 Not Found Date: Mon, 15 Oct 2012 19:37:43 GMT Server: Apache Expires: Sun, 19 Nov 1978 05:00:00 GMT Cache-Control: no-cache, must-revalidate, post-check=0, pre-check=0 Robots.txt just has User-agent: * Crawl-delay: 10 # Files Disallow: /cron.php How can I check what the issue is here?

• Where can I get a list or data base of light reflectance values for different materials?

  - by mikidelux

  I'm implementing lighting for a WebGL app but I'm not an artist so I don't know how to generate or where to obtain a list of materials with its values (diffuse, specular, ambient and shininess). I've been searching a lot but with no luck. Is there any list or DB I might have overlooked? Any common repository or something similar? Thanks in advance. Note: English is not my main language, let me know if you don't understand something and I'll try to rephrase it.

• Should I use events in this case?

  - by joon

  I'm creating a video player, like a custom YouTube player. All of the GUI elements (progress bar, video player, play button, ...) are different classes, but I obviously need them to communicate. When the progress bar is clicked, or the slider is moved, it needs to send a "seek(x)" command to the video player. Similarly, the video player needs to update the progressbar every frame. Currently I'm doing this by having almost all elements have a link to each other. So when I create the progress bar, I'm telling it where the video player is. But after a while this becomes more and more complicated, and I'm wondering if events would be a better way to do this. Or a main controller class that has all the connections. What should I do?

• GNU Emacs 23.2 disponible en version stable : l'éditeur de texte ultime pour les développeurs ?

  GNU Emacs 23.2 disponible en version stable L'éditeur de texte ultime pour les développeurs ? GNU Emacs est un éditeur de texte très puissant et particulièrement populaire au sein de la communauté des développeurs.

• How to get BURG on 12.10 (Quantal Quetzal)

  - by Warpspace

  I've been using BURG for years to get rid of the eye sore that is the standard GRUB interface. When I upgraded to Quantal, the repository does not contain the updated information. I.e. after I add sudo add-apt-repository ppa:n-muench/burg sudo apt-get update I get the annoying response W: Failed to fetch http://ppa.launchpad.net/n-muench/burg/ubuntu/dists/quantal/main/binary-amd64/Packages 404 Not Found It's been like this for a month, contrary to various websites which say it works. Is BURG being maintained? Have they created a better alternative (such as integration with GRUB, like it should have been in the first place). How do I get a decent-looking bootloader?

• Computer restarts when I choose my Lucid install from GRUB

  - by Alexx Hardt

  Hey, I have 4 OS's on my netbook, it's really more a toy. However, in my main OS (Ubuntu Lucid) is some data I don't like to lose. Today, whenever I choose this install from GRUB, the netbook (Asus eeePC 1001P if it's of help) waits 5 seconds (no kernel messages) and then reboots. The other entries (backtrack, Linux From Scratch, Windows XP) work fine. Can anyone hint me to where the error could be? It's not GRUB, right? So a reinstall wouldn't help? Is it the kernel? I'm afraid I didn't remember when and what the most recent automatic updates were.

• Why does IDLE continue to crash? [migrated]

  - by Dyana

  Idle keeps crashing and I can't figure it out. After restarting the computer and reinstalling Python, none of which seemed to work, I looked to my peers and was told to "install one of the Tcl/Tk". After getting another opinion I was also told that I already had this and found it to be true but decided to try it anyway since it continued to crash. Nothing has improved and I have an assignment due. Any ideas on why this continues to happen and what I can do to fix the crash? Problem details: Process: Python [1183] Path: /Applications/Python 3.3/IDLE.app/Contents/MacOS/Python Identifier: org.python.IDLE Version: 3.3.0 (3.3.0) Code Type: X86-64 (Native) Parent Process: launchd [793] Date/Time: 2012-11-05 14:10:54.124 -0500 OS Version: Mac OS X 10.7.5 (11G63) Report Version: 9 Interval Since Last Report: 181805 sec Crashes Since Last Report: 4 Per-App Interval Since Last Report: 20 sec Per-App Crashes Since Last Report: 4 Anonymous UUID: 68994A08-7FFB-4074-A553-CB60A60BB412 Crashed Thread: 0 Dispatch queue: com.apple.main-thread Exception Type: EXC_CRASH (SIGABRT) Exception Codes: 0x0000000000000000, 0x0000000000000000 Application Specific Information: * Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Error (1007) creating CGSWindow on line 263'

• XNA stopped compiling my model x files

  - by HuseyinUslu

  So I've a 3d game project I'm working on and I'm using 2 model files (SkyBlock.x and AimedBlock.x). So until now everything was all good and my models files were compiled all okay and I was able to use them within my game. With the latest changes (which I don't know what caused it really) - XNA stopped compiling my model files and instead only outputs files; AimedBlockxnb - 1kb SkyDome.xnb - 1kb SkyDomeTexture.xnb - 1389 kb SkyDomeTexture_0.xnb - 419 kb So I created a test XNA game project and moved all my asset's to new solution content project's and tried compiling them and saw that they're all good. AimedBlockxnb - 2kb SkyDome.xnb - 13kb SkyDomeTexture.xnb - 4097 kb SkyDomeTexture_0.xnb - 683 kb So I guess my main project sucks there but I couldn't came with a solution. I even tried overwriting my game's content project with new game's content project (which was all okay) but it didn't work. Anybody had similar issues?

• Google France risque un redressement fiscal qui pourrait dépasser les 100 millions d'euros, d'après l'Express

  Google France risque un redressement fiscal Qui pourrait dépasser les 100 millions d'euros d'après l'Express Google France serait-il en règle avec le fisc ? L'administration française en doute. L'Express révèle que la Direction nationale d'enquêtes fiscales et les Douanes ont effectué une perquisition au siège parisien de Google France le 30 juin 2011. Le fisc soupçonnerait la firme de ne pas avoir déclaré des revenus entre 2008 et 2010 portant sur la vente de publicités en France. Cette perquisition aurait permis de mettre la main sur de nombreux mails, des factures et pas mal de contrats. [IMG]http://ftp-developpez.com/sarah-mendes/4ea6428442bac0df9b47...

• Will I get penalised by google for overflow hidden? [duplicate]

  - by Rascal Capac

  This question already has an answer here: How bad is it to use display: none in CSS? 5 answers I have 2 divs next to each other, div A and div B. Div A displays a whole wordpress post and div B displays about 15 excerpts of posts with the same tag. To get this looking nice I set the hight of div B to be the same as the hight of div A with javaScript. This means alot of post excerpts will be hidden due to overflow hidden on div B. Will Google penalise me for this, and if so, how can I make this work and still please Google? Ps. I would gladly prevent the excerpts from being indexed but the main post must be indexed Ds.

• What are the Characteristics of a Software "Center of Excellence" (CoE)?

  - by Randy

  Recently a new director of my department came in and expressed his wish that we become a "center of excellence". I expected that since he is my first boss who actually has a programming background that there would be some description of this. However, it was left at that. As I reflected on this over the last few days, I am coming up empty on what a CoE actually means beyond just "being effective" at delivering the product. Here are the main items I am struggling with: Is this just a term that is thrown around by management types? What qualities make a group of software developers and testers excellent? How do you measure excellence in this context?

• Site inaccessible by some people, fine for others [on hold]

  - by Paul Howell

  A couple of days ago my website www.howellphoto.com (hosted by one.com, wordpress site) started loading really slowly, and I have been unable to access any pages linked from the homepage. Several of my friends have found the same issue, yet many are able to access the site without problem. Live support at one.com have not been all that much help, requesting the ip addresses of a few people who cannot access the site, and saying it could be a firewall issue. Wordpress support (my site was created in prophotoblogs) have been better and have updated all plugins, etc, but can see no issue from their end. My main issue is that even if there was a local fix that I could do on my computer, this would not help wih any potential customers visiting my site for information! This is driving me crazy!!! Any help will be legendary! Cheers, Paul
