• Android opengles 2.0 :different resolutions rendering and input

  - by kkan

  I'm currently developing a sprite based 2D game for android using opengles 2.0. I've got some basic rendering done that mimics the spritebatch functionality of xna (draw sprite, rotation, color). But all of this works for a fixed projection matrix, but android has a lot of screen sizes. Q1)Would this be an okay method to scale up/down the drawing? 1)Draw the whole screen to a texture. 2)Draw the above texture as a quad to the device. I found the above through some searching, not sure if it's the best one, are there any alternatives? Q2)How do you handle inputs for different resolutions? I currently get the position of a touch and use it raw. Would it be okay to get the position, and then scale the position to size of the texture used for rendering, and the perform calculations on it? Thanks.

• Unity mouse input not working in webplayer build

  - by Califer

  I have a button script with the following code void OnMouseDown() { animation.Play("button-squish"); enlarged = true; audio.PlayOneShot(buttonSound); } void OnMouseUpAsButton() { if (enlarged) { SelectThisButton(); enlarged = false; animation.Play("button-return"); } } void OnMouseExit() { if (enlarged) { enlarged = false; animation.Play("button-return"); } } It works great in the editor, but when I made a build and tested it in Chrome none of the buttons had any response. Further testing revealed that it did work in Firefox. Rather than telling people to change their browser if they want to play, I want to make the button code work. How else can I get the buttons to know when they're being pressed if the built-in stuff isn't working?

• Neural network input preprocessing

  - by TND

  It's clear that the effectiveness of a neural network depends strongly on the format you give it to work with. You want to preprocess it into the most convenient form you can algorithmically get to, so that the neural network doesn't have to account for that itself. I'm working on a little project that (surprise!) is going to be using neural networks. My future goal is to eventually use NEAT, which I'm really excited about. Anyway, one of my ideas involves moving entities in continuous 2D space, from a top-down perspective (this would be a really cool game AI). Of course, unless these guys are blind, they're going to be able to see the world around them. There's a lot of different ways this information could be fed into the network. One interesting but expensive way is to simply render a top-down "view" of things, with the entities as dots on the picture, and feed that in. I was hoping for something much simpler to use (at least at first), such as a list of the x (maybe 7 or so) nearest entities and their position in relative polar coordinates, orientation, health, etc., but I'm trying to think of the best way to do it. My first instinct was to order them by distance, which would inherently also train the neural network to consider those more "important". However, I was thinking- what if there's two entities that are nearly the same distance away? They could easily alternate indexes in that list, confusing the network. My question is, is there a better way of representing this? Essentially, the issue is the network needs a good way of keeping track of who's who, while knowing (by being inputted) relevant information about the list of entities it can see. Thanks!

• Microphone doesn't give any input, yet music does

  - by user52643

  I've tried a few guides but nothing works as of yet. I've tried two microphones, both of which work on my Vista setup but do nothing on Ubuntu. Nothing is on mute both on the Sound utility or Skype (which I'm trying to use my mic for). I've been informed that when my speakers are playing very load, this can be heard on the other end of a call, too. See link for cat /proc/asound/card0/codec#0 results which are apparently relevant... _' N.B. I am noob x

• Bluetooth Audio and SoftPhone Audio Input/Output

  - by o7th Web Design

  I have a Voip Softphone software that I would like to start using on my Ubuntu 14.04 box. Here's the thing. My system sound right now goes through my HDMI to my speaker system so I can play music all day ;-) I have a bluetooth headset connected to the machine as well. What I am wondering is if there is a way to: Auto-mute the music when a call comes in Auto-switch the sound devices when a call comes in, from my hdmi sound device, to my headset Auto-switch back when the call ends, and auto-un-mute the music Or even just an auto-switch to the headset? I can always pause the music ;)

• Writing a basic shader for large input files

  - by Zoltan Varadi

  I started writing a shader for my iOS app and instead of starting from scratch i used this tutorial here: http://www.raywenderlich.com/3664/opengl-es-2-0-for-iphone-tutorial I wrote an import function, first to import wavefront .obj models. My problem is that with I can't handle larger inputs (with a simple cube it was working). I realized that the indices array is an array of GLubyte values, which is unsigned char, so as a result i cant have more than 256 indexes. I modified it to GLuint, but then only get a blank screen. What else needs to me modified? p.s.: the source can be downloaded from here: http://d1xzuxjlafny7l.cloudfront.net/downloads/HelloOpenGL.zip

• How do I output my audio input?

  - by VarLogRant

  A few iterations ago, I think this was Jaunty but could've been before, I would plug a 1/8" audio cable from the line-out of a Windows netbook to the line-in of my Ubuntu machine, so I would have all the sound from both machines without having to plug both into a mixer which I don't have. I didn't do this much, as I was pretty-much happy with Banshee at the time. But with Karmic, and still with Lucid, I can only get the output if I'm recording with Audacity. Which I'm not going to do from my web-development and systems programming workstation. I can tell by plugging in headphones that my netbook has audio out working. I can see Sound Preferences that the Ubuntu machine is receiving them. I just want the old behavior back. Help?

• Hiding my location to websites with region-specific languages/content

  - by Tudor

  I just went to download Microsoft Secority Essentials and it enraged me as it redirected me to a site in my home language and not the default English. If I go to America, I don't want them to speak Swahili. It reminded me of all the other websites who try to do the same. I don't want my content in greek when I'm on vacation! I for one simply can't work on a computer unless the language is English (or unless there's a VERY good reason to change the language). Location aware content is only good for download mirrors, and even then I would rather pick from a list of countries myself. (or if you can't speak anything but your own language) I know websites get your location from your IP and ISP, but is there any way you can inhibit this behaviour on a browser level? Is there any Chrome/Firefox extension for it? Do I really have no choice but to hide my IP? There's all sorts of services that claim they're hiding your IP for free so that people can't log and trace your steps through the internet, but they're probably logging it themselves and making money off it. Why else would they be free? I've found that Firefox has an Option that says "Choose your preferred language when displaying pages". Haven't found anything for Chrome.

• How to stop windows from adding additional keyboards to languages

  - by MMavipc

  I have the English language setup with the normal en-us layout, and only this layout. I have the Spanish language setup with united states - international layout. When I switch to English it gives me the option to select the regular keyboard or the international version. Only the regular version is listed under EN in my language settings. How do I get it to remove the international keyboard from English? Sometimes it switches to international while I'm on English mode and screws up my typing, which is a pain in the ass.

• Source of parsers for programming languages?

  - by Arkaaito

  I'm dusting off an old project of mine which calculates a number of simple metrics about large software projects. One of the metrics is the length of files/classes/methods. Currently my code "guesses" where class/method boundaries are based on a very crude algorithm (traverse the file, maintaining a "current depth" and adjusting it whenever you encounter unquoted brackets; when you return to the level a class or method began on, consider it exited). However, there are many problems with this procedure, and a "simple" way of detecting when your depth has changed is not always effective. To make this give accurate results, I need to use the canonical way (in each language) of detecting function definitions, class definitions and depth changes. This amounts to writing a simple parser to generate parse trees containing at least these elements for every language I want my project to be applicable to. Obviously parsers have been written for all these languages before, so it seems like I shouldn't have to duplicate that effort (even though writing parsers is fun). Is there some open-source project which collects ready-to-use parser libraries for a bunch of source languages? Or should I just be using ANTLR to make my own from scratch? (Note: I'd be delighted to port the project to another language to make use of a great existing resource, so if you know of one, it doesn't matter what language it's written in.)

• Theory of formal languages - Automaton

  - by dader51

  Hi everybody ! I'm wondering about formal languages. I have a kind of parser : It reads à xml-like serialized tree structure and turn it into a multidimmensionnal array. I figured out that i need at least three variables to achieve the job : $tree = array(); // a new array $pTree = array(&$tree); // a new array which the first element points to $tree; $deep = 0; plus the one containing the sentence splitted into words. My point is on the similarities between the algorithm deing used and the differents kinds of automatons ( state machines turing machines stack ... ). The $words variable is the "tape" of the automaton, the test/conditions of the algorithm are transitions, $deep is the state and $tree is the output. I cannont figure what is $pTree. So the question is : which is the automaton I implictly use here, and to which formal languages family does it fit ? And what's about recursion ?

• Switching languages on a website with PHP

  - by jnkrois

  Hello everybody, I'm just looking for some advice. I'm creating a website that offers (at least) 2 languages. The way I'm setting it up is by using XML files for the language, PHP to retrieve the values in the XML nodes. Say you have any XML file, being loaded as follows: <?php $lang = "en"; $xmlFile = simplexml_load_file("$lang/main.xml"); ?> Once the file contents are available, I just output each node into an HTML tag like so: <li><?php echo $xmlFile->navigation->home; ?></li> which in turn is equal to : <li><a href="#">Home</a></li> as a nav bar link. Now, the way in which I'm switching languages is by changing the value of the "$lang" variable, through a "$_POST", like so: if(isset($_POST['es'])){ $lang = "es"; }elseif(isset($_POST['en'])){ $lang = "en"; } The value of the "$lang" variable is reset and the new file is loaded, loading as well all the new nodes from the new XML file, hence changing the language. I'm just wondering if there is another way to reset the "$lang" variable using something else, other than "$_POST" or "$_GET". I don't want to use query string either. I know I could use JavaScript or jQuery to achieve this, but I'd like to make the site not too dependable on JavaScript. I'd appreciate any ideas or advice. Thanks

• When opening a file in perl, how can I automatically use STDIN/OUT if the file name is "-"?

  - by Ryan Thompson

  I have a perl program that takes input and output file arguments, and I'd like to support the convention of using "-" to specify standard input/output. The problem is that I can't just open the file name, because open(my $input, '<', '-') opens a file called -, not standard input. So I have to do something like this: my $input_fh; if ($input_filename eq '-') { # Special case: get the stdin handle $input_fh = *STDIN{IO}; } else { # Standard case: open the file open($input_fh, '<', $input_filename); } And similarly for the output file. Is there any way to do this without testing for the special case myself? I know I could hack the ARGV filehandle to do this for input, but that won't work for output.

• The use of getters and setters for different programming languages [closed]

  - by leonhart88

  So I know there are a lot of questions on getters and setters in general, but I couldn't find something exactly like my question. I was wondering if people change the use of get/set depending on different languages. I started learning with C++ and was taught to use getters and setters. This is what I understand: In C++ (and Java?), a variable can either be public or private, but we cannot have a mix. For example, I can't have a read-only variable that can still be changed inside the class. It's either all public (can read and change it), or all private (can't read and can only change inside the class). Because of this (and possibly other reasons), we use getters and setters. In MATLAB, I can control the "setaccess" and "getaccess" properties of variables, so that I can make things read-only (can directly access the property, but can't overwrite it). In this case, I don't feel like I need a getter because I can just do class.property. Also, in Python it is considered "Pythonic" to not use getters/setters and to only put things into properties if needed. I don't really understand why its OK to have all public variables in Python, because that's opposite of what I learned when I started with C++. I'm just curious what other people's thoughts are on this. Would you use getters and setters for all languages? Would you only use it for C++/Java and do direct access in MATLAB and Python (which is what I am currently doing)? Is the second option considered bad? For my purposes, I am only referring to simple getters and setters (just return/set the value and do not do anything else). Thanks!

• Python vs all the major professional languages [closed]

  - by Matt

  I've been reading up a lot lately on comparisons between Python and a bunch of the more traditional professional languages - C, C++, Java, etc, mainly trying to find out if its as good as those would be for my own purposes. I can't get this thought out of my head that it isn't good for 'real' programming tasks beyond automation and macros. Anyway, the general idea I got from about two hundred forum threads and blog posts is that for general, non-professional-level progs, scripts, and apps, and as long as it's a single programmer (you) writing it, a given program can be written quicker and more efficiently with Python than it could be with pretty much any other language. But once its big enough to require multiple programmers or more complex than a regular person (read: non-professional) would have any business making, it pretty much becomes instantly inferior to a million other languages. Is this idea more or less accurate? (I'm learning Python for my first language and want to be able to make any small app that I want, but I plan on learning C eventually too, because I want to get into driver writing eventually. So I've been trying to research each ones strengths and weaknesses as much as I can.) Anyway, thanks for any input

• Set up heads up for two people

  Is there a way to set up a Mac or Linux so that one can connect two mice and two keyboards with both users having independent input on the screen with their respective mice and keyboards? I'd like to set up an environment for pairwise programming, and in particular have two developers be able to concurrently edit different documents on the same computer screen, but each person having different keyboards and mice. I'd be much obliged for any input and direction.

• Have problems designing input and output for a calculator app

  - by zoul

  Hello! I am writing a button calculator. I have the code split into model, view and a controller. The model knows nothing about formatting, it is only concerned with numbers. All formatting is done in the view. The model gets its input as keypresses, each keypress is a part of an enum: typedef enum { kButtonUnknown = 0, kButtonMemoryClear = 100, kButtonMemoryPlus = 112, kButtonMemoryMinus = 109, kButtonMemoryRecall = 114, kButtonClear = 99, … }; When the user presses a button (say 1), the model receives a button code (kButtonNum1), adds the corresponding number to a string input buffer ("1") and updates the numeric output value (1.0). The controller then passes the numeric output value to the view that formats it (1). This is all plain, simple and clean, but does not really work. The problem is that when user enters a part of a number (say 0.00, going to enter 0.001), the input does not survive the way through model to view and the display says 0 instead of 0.00. I know why this happens ("0.00"::string parses to 0::double and that gets formatted as 0). What I don’t know is how to design the calculator so that the code stays clean and simple and the numbers will show up on screen exactly as the user types them. I’ve already come with some kind of solution, but that’s essentially a hack and breaks the beautiful and simple flow from the calculator model to the display. Ideas? Current solution keeps track of the calculator state. If the calculator is building a number, I take the calculator input buffer (a string) and directly set the display contents (also a string). Otherwise I take the proper path, ie. take the numeric calculator output, pass it to the view as a double and the view uses its internal formatter to create a string for the display. Example input: input | display | mode ------+---------+------------ 0 | 0 | from string 0. | 0. | from string 0.0 | 0.0 | from string 0.0+ | 0 | from number This is ugly. (1) The calculator has to expose its input buffer and state. (2) The view has to expose its display and allow setting its contents directly using a string. (3) I have to duplicate some of the formatting code to format the string I got from the calculator input buffer. If user enters 12345.000, I have to display 12,345.000 and therefore I’ve got to have a commification code for strings. Yuck.

• Test for absence of an input tag's value attribute

  How can I confirm the absence of a HTML attribute in a Rails RSpec test? I can verify that an input tag has a value attribute and that it is an empty string like so: response.should have_tag("input[name=?][value=?]", "user[password]", "") response.should have_tag("input[name=?][value=?]", "user[password_confirmation]", "") But what I want to do is verify that my input fields do not have a value attribute at all (i.e., a blank field).

What is it about Python (features, etc) over other languages that you love? The reason I usually give is that in Python you forget about the complexities and frills of programming languages and can just focus on producing code that works... What do you think?
