• Render graphics using Doubles in Graphics2D

  - by thedeadlybutter

  Currently, I have a JFrame for my game to render in, and I'm using Graphics2D for drawing (The games graphics are fairly simple 2D sprites). However, my delta variable is a double, and all of the Graphics 2D methods (And Grpahics) use int. I tried to type cast the delta to an int, but it just rounds down to 0. So my question is, how can I render graphics using Graphics2D in Java with coordinates that are doubles. Can I convert it to work with Graphics2D if there is no built in way? Or, is there a graphics library that can support doubles for coordinates?

• Applying prerecorded animations to models with the same skeleton

  - by Jeremias Pflaumbaum

  well my question sounds a bit like, how do I apply mo-cap animations to my model, but thats not really it I guess. Animations and model share the same skeleton, but the models vary in size and proportion, but I still want to be able to apply any animation to any model. I think this should be possible since the models got the same skeleton bone structure and the bones are always in the same area only their position varies from model to model. In particular Im trying to apply this to 2D characters that got 2arm, 2legs, a head and a body, but if you got anything related to that topic even if its 3D related or keywords, articles, books whatever Im gratefull for everything cause Im a bit stuck at the moment. cheers Jery

• manage 2 wireless device

  - by yi.tang.uni

  I erased Windows 7 and installed Ubuntu 12.04 on my Dell Latitude E4200. I an very happy with my choice but with little pity. I cannot use the wireless service in my university as the build-in device works unstable. I bought a USB wireless device, which solve the problem. However, the build-in device keep to sent me message about unable to connect, which waste laptop's cup & battery. The phsical bottom to turn off wireless affect both devices. So the question is: "How can I manually shut down wireless device?" There is another interest comes to my mind: "Does 2 wireless improve the overall internet usage if I run a high-internet-consuming program like BT ?" Thank for your time and energy.

• Best choise of gui platform/framework for 3d development [closed]

  - by Miguel P

  The title pretty much says it all, so I'm developing a 3d engine for Directx 11, and it's going good so far. I started using .net forms as a GUI, but then(Of curiosity), i jumped to MFC, and the app looked great, but in my perspective, MFC is badly written, and it's too complicated, meaning that some things just took forever, while it would have taken a few seconds in .net forms. But my real question is: If i want to make an Editor for a 3d scene, where directx renders in the form( This was accomplished in .net forms), what would be the best choise of gui platform/framework? MFC,.net forms, Qt, etc....

• Looking for a very subtle unit testing example

  - by Stéphane Bruckert

  In the context of Continuous Integration, I need to teach unit testing to a 20-people audience of programmers. Everything will be all right, but I am still trying to find the perfect unit testing example. More than writing tests like a robot, I want to show that unit testing can help prevent very subtle errors. I am thinking of the following scenario to happen when doing a live TDD demo: the test cases would already be written, we would have to write methods together, most of us would naturally have forgotten to handle a specific case for a method, everyone would then be surprised, when seeing that all tests don't pass, the failing test would make us think more and realize that we forgot an important case. My question will probably finish as "too broad" or "not clear what you are asking", but we never know, one of you might have a great idea. Your answer can use Java and JUnit, though any other language will be fine since only the idea will matter.

• How do I simulate the mouse and keyboard using C# or C++?

  - by Art

  I want to start develop for Kinect, but hardest theme for it - how to send keyboard and mouse input to any application. In previous question I got an advice to develop my own driver for this devices, but this will take a while. I imagine application like a gate, that can translate SendMessage's into system wide input or driver application with API to send this inputs. So I wonder, is there are drivers or simulators that can interact with C# or C++? Small edition: SendMessage, PostMessage, keybd_event will work only on Windows application with common messages loop. So I need driver application that will work on low, kernel, level.

• Find "secret" port number

  - by CJ Sculti

  this may be kind of an odd question. My friend has challenged me. So somehow, he change the "port" of his site to 31337. If you just go to domain.com, you get redirected to google, to access the real site you go to domain.com:31337. He is going to change it again and he is challenging me to find out which port it is. Is this possible without guessing? Hopefully someone can help! Thanks. Oh, and is this the right stack exchange site to post this on...

• What the different hardware temperatures listed in psensor, sensor viewer etc reffer to?

  - by cipricus

  I have installed psensor and see a list of temperatures, but listed as ”Temperature 1”, 2, 3 etc . I can only guess where the processor is: but who's who for sure? The same question stands for Sensors Viewer. I can also type sensors in Terminal but I get no more than that acpi -t gives Thermal 0: ok, 65.0 degrees C Thermal 1: ok, 37.9 degrees C Thermal 2: ok, 56.0 degrees C Thermal 3: active, 71.0 degrees C Considering psensor, I know for a fact that: - the temperature that varies most depending on the CPU use is Temp1 and it is one of the two highest - the other high temperature is Temp4 and it goes to the ceiling when using youtube/flash - Temp2 is very stable at a medium level of 50-60 degrees Celsius - Temp3 is by far the lowest and most imobile So, I guess Temp1 is the CPU temperature, and Temp4 is the GPU temperature. Temp2 and 3 must be the motherboard and the hdd. Does anybody know for sure?

• java framework for a web wizard

  - by snippl

  I'd like to create a web wizard or a wizard on/within a website. I know there are several java frameworks for wizards but there is none for the web in particular. If I search for a framework, I always get wizards to create a website, applet, servlet and what not. But never how to create such a wizard itself. So the question(s) is: What framework should I use to create a web wizard? And what frameworks are there? The wizard will be the visualisation for a BPEL Process deployment on a apache ode. I thought a webapp would be an easy way because the apache is running anyway. I'm not bound to that, perhaps someone has a better idea.

• wordpress woocommerce php variable usage %1$s

  - by tech

  I am using wordpress with woocommerce and I am trying to manipulate a copy of myaccount.php The default code uses some variables of some sort that I am not familiar with nor have I been able to find documentation on. The variables in question are %1$s, %2$s and %s <p class="myaccount_user"> <?php printf( __( 'Hello <strong>%1$s</strong> (not %1$s? <a href="%2$s">Sign out</a>).', 'woocommerce' ) .

• Redirect AFTER Initiating download

  - by mashup

  I have a question - is there any way to initiate a download and AFTER the user has confirmed the download then redirect to another site? Is something like that possible via ASP or another language commonly used for websites? Bad PHP "user experience" scenario (In use right now) a) User comes to site, clicks download button b) Users sees "download" landing page, gets redirected after 5 seconds c) Download starts on Thankyoupage Good "user experience" scenario: (my dream solution, what I want) a) User comes to site, clicks download button b) Download starts immediately on landing page c) Download confirmed, redirects now to thank you page Any programming language is a go for this.

• Why is bzip2 needed in the kernel patch instructions?

  - by user12657

  This was from here. Extract the patch tar -xvzf /usr/src/web100-2.5.22-200810130047.tar.gz bzip2 web100/ web100-2.6.27-2.5.22-200810130047.patch Test the patch bzip2 -dc /usr/src/linux/web100/ web100-2.6.27-2.5.22-200810130047.patch.bz2 | patch -p1 --dry-run I looked at the .patch, the diff output of many files and the file .patch.bz2 after the bzip2 command which is too also the diff output of many files, they seem to be the same. My question is why is bzip2 even needed to turn the .patch into a .patch.bz2? Is it for the redirection to std output from the -dc option for the patch command? Even if it is, why not just not just use the patch command in the form something like this:patch -p1 < patchfile? I don't see why the bzip2 is done here. Also, I think the bzip2 might have an extra space in the command after web100/, right?

• What is the right level of granularity for code commenting?

  - by Nick

  Commenting in code I believe is very important but recently I've been reviewing code that has left me wondering particular this one. //due to lack of confidence with web programming leaving this note in for now What is the right level of granularity for code commenting? EDIT: Obviously the above comment is shocking hence why I'm asking the question. I've recently noticed the inline comments in the code at my work place annoying. Instead of getting angry I want discovery the acceptable level of granularity for code commenting in the community.

• What constitutes proper use of threads in programming?

  - by Smith

  I am tired of hearing people recommend that you should use only one thread per process, while many programs use up to 100 per process! take for example some common programs vb.net ide uses about 25 thread when not debugging System uses about 100 chrome uses about 19 Avira uses more than about 50 Any time I post a thread related question, I am reminded almost every time that I should not use more that one thread per process, and all the programs I mention above are ruining on my system with a single processor. What constitutes proper use of threads in programming? Please make general comment, but I'd prefer .NET framework thanks EDIT changed processor to process

• How to deal with tautology in comments?

  - by Tamás Szelei

  Sometimes I find myself in situations when the part of code that I am writing is (or seems to be) so self-evident that its name would be basically repeated as a comment: class Example { /// <summary> /// The location of the update. /// </summary> public Uri UpdateLocation { get; set; }; } (C# example, but please refer to the question as language-agnostic). A comment like that is useless; what am I doing wrong? Is it the choice of the name that is wrong? How could I comment parts like this better? Should I just skip the comment for things like this?

• Why didn't IE8 support border-radius, evil or ignorance?

  - by Mark Rogers

  When I think back to the time of the release of IE7, I was surprised that there wasn't border-radius support. It seems like an obviously great idea to have a css-property name for rounded corners, which can potentially make a site look less like it came from the computer stone-age. Finally, today we have IE9 and Microsoft finally decided to play ball with the rest of the world. But the question remains, why didn't Microsoft bother to support border-radius in IE8? The problem probably became obvious to the company as the growing chorus of complaints from web developers got louder after the release of IE7. Was the company so isolated or in group-think mode that they were blind for that many years? Or did Microsoft have some additional motive to suppress the border-radius property?

• How can I initialize file names in the folders/ subfolders?

  - by user37991

  Sometimes Thunar allows 'camel-case' of file names, but only in the immediate folder, not the sub-folders. "Perl module to convert stringt to and from CamelCase" exists in Synaptic, but it is not powerful enough, or am I ignorant? The only way I can reliably do this is with Windows shareware (paid $$): Servant Salamander). That's why all my data & archives are on NTFS partitions. BTW: Synaptic has different entries for 'initialize' and 'initialise'. But I'll mention this in another question.

  - by hal9k2

  As in the question above: What the best way to wire up Entity Framework database model (context) to viewModel in MVVM (WPF)? I am learning MVVM pattern in WPF, alot of examples shows how to implement model to viewModel, but models in that examples are just simple classes, I want to use MVVM together with entity framework model (base first approach). Whats the best way to wire model to viewModel. Thanks for answers. //ctor of ViewModel public ViewModel() { db = new PackageShipmentDBEntities(); // Entity Framework generated class ListaZBazy = new ObservableCollection<Pack>(db.Packs.Where(w => w.IsSent == false)); } This is my usual ctor of ViewModel, think there is a better way, I was reading about repository pattern, not sure if I can adapt this to WPF MVVM

• Is Ubuntu running well on an usb hdd? Need suggestions

  - by Klaus

  Dear Linux and Ubuntu pros, I have here a company notebook, and because the hdd is full encrypted I cannot install an extra partition for another system that I would like to use in my free time. And I really need another system, because this crap windows here with that much of antivirus, antispyware, anti-whatever on it is sooo slow and anoying. What can I do? I could use an external usb hdd with another system. Because I would like to handle big files and so on, I dont want to use an sub stick. An usb 2.5hdd + ubuntu is what I think the best option. Here are my question: Do I have to note something? Is Ubuntu running well on an external hdd? Do I have big performance problems (because of the usb hdd)? Should I buy a very fast hdd for much money or is it not that important? Any suggestions? Thank you :)

• How do I go from a simple html5 tic tac toe game to an online 2 player game?

  - by phi1o

  I've been working on an online 2 player Tic Tac Toe solution for blackberries. both old and new. And so far I have html5 code that has a 3 x 3 layout that switches between x and o for the game mechanics. I believe I'm still missing a check for win function but my question is about the server side of this game. I'm not sure how to go about learning what exactly I want. how do you take what I have now, and make this into a functioning online game? I've been told WAMP is a good solution, as well as IIS. and its all really over my head, so i'm hoping to get a little more clarity as far as what I should focus on to bring this game to life.

• How do I reset my Ubuntu user password?

  - by Myself

  I lost my Ubuntu user account password... I saw some other questions on this topic that had answers telling me to restart the computer, press the left shift key after BIOS, go to root, type "passwd [username]" and all this other stuff, but none of that worked. After I typed a new password and retyped it, it gave me an error message saying something like "Authentication Manipulation Error." There was another question complaining about this, but there weren't any useful answers that worked. Does anybody know of a way for me to retrieve or reset my password? Am I doing something wrong with that method I mentioned?

• I Need a recommendation for a CMS application with ECommerce

  - by Griff

  Does anyone have any recommendation for an open source solution for a robust CMS application that has a fully featured ECommerce module? I have been looking into Drupal with Ubercart -- but it looks like Ubercart is not fully up to speed with Drupal 7, and the other modules for Ecommerce don't look as robust. The CMS system should support CMIS as both client and server, and be able to run in a cloud computing environment. The system could be written in any standard web programming language, although Java would be my preference. I'm posting this question here because it seems that all CMS systems provide ECommerce as an afterthought, rather than a core feature.

• Use hotplug and turn on/off PCI device for replacing NIC
