• Is it possible to keep GNOME 2 in 11.10?

  - by RevenNL

  Unity has been both praised and hated by different people for various reasons. Mark Shuttleworth for example says that it's designed for widescreens as an example. I do fully agree with that statement, however due to the fact that I do not have a widescreen (1280x1024) Unity simply doesn't function smoothly for me. That's what it's important for me to have a good alternative. Since I really loved Gnome 2, I'd like to ask if it's possible to keep using that in Ubuntu 11.10 or would you guys suggest another alternative and if so why?

• How do I convert screen coordinates to between -1 and 1?

  - by bbdude95

  I'm writing a function that allows me to click on my tiles. The origin for my tiles is the center, however, the mouse's origin is the top left. I need a way to transform my mouse coordinates into my tile coordinates. Here is what I already have (but is not working): void mouseClick(int button, int state, int x, int y) { x -= 400; y -= 300; float xx = x / 100; // This gets me close but the number is still high. float yy = y / 100; // It needs to be between -1 and 1 }

• Key Handling mechanics

  - by Max

  I am new to game development and am working on my first game using OpenGL and C++. I have a game class which handles everything necessary in an update() function. Now i want to handle keyboard inputs. I use GLFW which supports key callbacks. However i wonder how to deal with inputs. Should i record the keys pressed and poll on it the next time my game updates or should the callback immediately perform the necessary actions? And why? Thanks :)

• How to elegantly work with a lot of print functions?

  - by user1824372

  I'm working on a Python project that is executed on a terminal (or console) for which I am planning to implement a GUI. I did not major in CS so I really have no idea how to effectively design a terminal GUI such that: the user interface looks good in GUI, it is directed to a certain widget, let's say, a text label, or a bottom bar, or a hide-able frame. Do you have any suggestions? Currently, I am using the print function to provide essential information on STDOUT during execution, so a lot of print calls are distributed here and there in the code. I'm thinking of using macro-like variables such as 'FILE_NOT_EXISTS_MESSAGE' for printing, and all of them and their values would be defined in one file. Is that a standard way to do this? Should I introduce a logging system? In summary, I'm looking for a pattern for handling console output that is effective and adaptable.

• A c++ program that computes the min and max of f(x) for a rectangle inputed by user

  - by StreetBallerX

  So bassicly this is the problem quoted from my teacher : "You have to write a program in C++ that computes the minimal and the maximal value of function f(x,y) obtained on an integer point in a given rectangle [a, b] x [c, d]. Your program should prompt the user to input numerical values of a, b, c and d, as floating point numbers, which are expected to be in a range from -100 thru 100. In case when minimal or maximal values do not exists, your program should output appropriate messages. f(x,y)=x+x*x+x*x*x+y+y*y " So before anyone tell me that i should try do it myself , i'll tell them that ive been trying to do it myself for the past 8 days but my deadline is aproaching and i just cant figure it out its a really simple program but i just cant understand it ... I wont post my attempts because all i saw in these forums is that when someone posts their try and a milion people start to say dont look it this way thry this and bla bla and the guy who posted it was just wondering for minor thing ... so what ever thank you all in advance and thats it :)

• pascal triangle in php (anything wrong with this solution?) [migrated]

  - by zhenka

  I saw that one of the interview questions could be building a pascal triangle. Is there anything wrong with this particular solution I came up with? function pascal_r($r){ $local = array(); if($r == 1){ return array(array(1)); } else { $previous = pascal_r($r - 1); array_push($local, 1); for($i = 0; $i < $r - 2 && $r > 2; $i++){ array_push($local, $previous[$r-2][$i] + $previous[$r-2][$i + 1]); } array_push($local, 1); } array_push($previous, $local); return $previous; } print_r(pascal_r(100));

• XNA tempory pause

  - by Marivs

  I need to do a temporary pause. If I do a collision with an enemy I want to pause the game for 1.5 seconds. Take a look here to my code: bool tPause; float timer; public ovveride Update(GameTime gameTime) { if(!tPause) { //... if(enemy.rectangle.Intersects(player.rectangle)) { timer+=(float)gameTime.ElapsedGameTime.TotalMilliseconds; tPause=true; if(timer>1500) { tPause=false; timer=0; } } //... } } It doesn't function.

• System.getProperty("user.dir") cannot get my project root path ,but the path which my eclipse is located

  - by facebook-100005613813158

  As the title goes , I have class named GetException.java,inside it ,I read a xml file in a static code block like(Because this document is shared): static{ ... document = db.parse(new File(System.getProperty("user.dir")+"/src/exception/ExceptionCode.xml")); ... } To test if the file path is correct, I write a main function just inside GetException.java, it proves that the path is correct ,xml file can be read successfully. My project root dir is "/home/wuchang/workspace/MongodbI". But When this Class is loaded from other class,such as I called one of its static functions , it reports the error message: /home/mrs/??/eclipse/src/exception/ExceptionCode.xml (No such file or directory) /home/mrs/??/eclipse/ is actually my eclipse installation directory.So , I wander how System.getProperty("user.dir") returned the eclipse installation directory to me ,instead of my project root directory?

• How to learn programming from very basic level to advanced level? [closed]

  - by user1022209

  I know many programming languages ,skills and concepts in very basic, such as PHP, Java, Object-oriented technology. Using PHP, I can build a simple website with CRUD, login function. Using Java, I can make an basic swing csv/plain text editor in which user can switch between 2 different views. In term of object-oriented Technology, I clearly understand what encapsulation, inheritance and Polymorphism are I want to know more about programming. Sometimes I "google" some of the topics I am interested at , the more I see on the internet, the more I feel I am a small potato in the world ( indeed I am ). The codings/concepts are difficult to understand. I lacks confidence right now so I am asking this question :( What is the best way to learn programming to advanced level? Just buy a book and read it page to page? Thanks for any helps

• PHPmyedit: custom URL for 'ADD' button [on hold]

  - by user2952715

  I'm currently working with phpmyedit and I need to access to the 'Add' (new record) function using a URL. As this script (phpmyedit) is dinamically generated, when I press the 'Add' button, I get the form to fill but the URL has no changes. How can I create some custom URL for the ADD button, that allows me to access externally and also pass parameters through the URL? Here is how PHPmyedit set up the navigation buttons by default: http://opensource.platon.sk/projects/doc.php/phpMyEdit/html/configuration.navigation.html Any help will be really appreciated.

• Touchpad stop working

  - by Diegov

  I'm in a HP 430 PC-Notebook using Oneiric. And sometimes my touchpad just stop working :(... I haven't installed anything, just safe playing with terminal following linuxcommand.org BTW my touchpad has a "hole" that in Windows, it works like this: two touch, block touchpad, two touch, unblock. And as far as I now, Ubuntu hasn't recognize this function so I think that the "hole" is not the problem... Also, I'm pretty sure that I haven't touch a little that... PD: Spanish speaker, sorry if "hole" is not the appropriate term haha.. Thanks!

• Physics for moving blocks

  - by Gabson

  I'm working on a 2D game for windows phone where the player moves blocks around to bounce a laser beams. I need to create some simple physics for moving the blocks. For the moment I have a simple collision class, telling me if two rectangles collide. But that's not enough because when I'm moving a block the rectangle/rectangle function doesn't work. By Doesn't work i mean,I manage the collision but I don't how to stop the block mooving while the user sliding the block. The collision response for the block I want is if the user tries to slide it on another object, the block should slide up against the other object and not overlap. How would I go about implementing this functionality?

• How to turn off power management for external hard drive (Seagate GoFlex)?

  - by RPG Master

  I bought this 2tb Segate GoFlex this last Black Friday and since then every 15 minutes or so the drive spins down, and then a little while later completely dismounts. Very annoying. From what I understand you could turn this off using the including Windows and Mac only software. This function and what controls it isn't proprietary, right? There has to be something that'll let me set it in Ubuntu... Anyone have any suggestions? Also, I formatted it to EXT4. Hope I didn't screw myself up. :/

• Does a large (hidden) submenu count towards site content in tems of determining page similarities?

  - by Name

  Basically, I have this site that recently lost a lot of traffic after I optimized the html, the exact reasons to which are uncertain. The graph of impressions (times a page appears on search listings) is continuously going down like an e^-x function. Because the content, previously occupying five pages of tables, now fits within a few paragraph tags, the menu now occupies about 80% of the live html code and I am starting to have doubts wherether this affects the "similar pages" factor that Google punishes. Questions: As far as I know, Google ignores invisible material and the submenus are only visible when hovered over. Has anything at all changed in this area? If I ajax in the submenus, leaving only the main eight menu items to load, will I be punished for "hiding" information? Is the idea worth testing or is it frankly retarded?

• Second monitor stopped working

  - by Mark D

  After setting up 11.10 today, I seem to be having problems with my dual monitor set up. It worked without issues in Mint but today after I switched to 11.10 only one monitor seems to function. This seems a little odd to me. During setup both monitors functioned without issue, although they were mirroring each other both monitors but as soon as it booted into Unity my secondary monitor stopped working. I checked under settings-display and the second monitor doesn't seem to even be detected. On the off chance it had something to do with drivers, I upgraded the proprietary drivers to the latest version with zero success. If anyone has any ideas, I'd love to hear them.

• Is there a way of leveling/compressing the sound system-wide?

  - by JethroDawnfine

  As a Laptop user, I'm sure that a lot of people, even the ones using Netbooks would have already gone through this problem. Especially when listening to podcasts, and using it as an example, the sound might have loud moments and quiet moments, one person speaking loud and the other speaking very quiet in the same episode. Thereby, I always wanted the sound to be compressed system-wide, and I just noted the other day, that in Windows, some Realtek drivers already offer this function. We have already a pulseaudio plugin for equalization system-wide, and although it still has problems like not letting us change its values and listen the change in real time, or cracking the sound while changing pulse volume, I do love it and use it. Now I'm just missing something to keep the sound around 0db (or near the volume level you're using) as a leveler plugin for pulseaudio. Any suggestion?

• Multiple parameters vs single parameter(object with multiple properties)

  - by Shwetanka

  I have an Entity Student with following properties - (name, joinedOn, birthday, age, batch, etc.) and a function fetchStudents(<params>). I want to fetch students based on multiple filters. In my method I have two ways to pass filters. Pass all filters as params to the method Make a class StudentCriteria with filters as fields and then pass the object of this class While working in java I always go with the second option but recently I'm working in php and I was advised to go with the first way. I am unable to figure out which way is better in maintaining the code, reusability and performance wise. Thanks.

• How do I correctly multiply an XMMATRIX by a scalar?

  - by user43129

  Using DirectXMath and its XMMATRIX structure in C++ and Direct X 11, how does one multiply that matrix structure by a single float scalar? I want to implement the operation B = A * f; where A and B are XMMATRIX and f is a float. I found all sorts of functions to multiply a matrix by another matrix or a vector. I found all sorts of functions to construct matrices. I could find no scalar multiplication! Why is there no such function? Is there no use case? Did I miss something? How do I implement scalar multiplication?

• Driver inversion

  - by Val

  I have a GUI game, which is driven by user every time it clicks the mouse. Every time user clicks a square on a board, the board state is updated (we re-compute the score, the player to make next move and legal movements it can make) and repainted. Both mouse click, state recomputation and painting are handled in the GUI thread. Now, suppose that I want to train AI to play without GUI. That is, game engine should consume next move by simply calling AI's makeMove function in one thread. This would allow to play millions of games per second automatically. GUI may just screenshot some arbitrary states time after time. How do you switch to this strategy?

• Advise how to write a simple test for this javascript snippet?

  - by resting

  I'm trying to start unit testing (not using any testing frameworks) for my javascripts. Here's one example of it. var obj = {}; obj.disableBtn = function ($btn, style) { $btn.attr('disabled','disabled').addClass('disabled').removeClass(style); }; The use case is as such: obj.disableBtn($('.submit'), 'btn-blue'); What it does is simply add the disabled attribute, add the disabled class, and remove the btn-blue style. Please advise how would a typical test case look like in this case. I have a little knowledge on testing using assert(), but have no idea how to go about it when it involves verifying the result on HTML elements.

• amixer volume controls applies twice

  - by user214604

  The volume increment or decrement is happening double the intended amount using amixer for my alsa driver using ./amixer -c 0 set Master 1- command. This happens becuase by default volume controls apply for both playback and capture moduels. My alsa driver config doesnt enabled any of the capture controls. even there is no capture enabled, the function from simple_none.c returns true for capture channel. All the capture volume controls are applied to my playback driver. static int is_ops(snd_mixer_elem_t *elem, int dir, int cmd, int val) case SM_OPS_IS_CHANNEL: return (unsigned int) val < s-str[dir].channels; ./amixer -c 0 set Master Playback 10+ ./amixer -c 0 set Master Playback 10 - ./amixer -c 0 set Master Capture 10+ ./amixer -c 0 set Master Capture 10 - I suspect capture is enabled by default in my system for alsa drivers. Let me know what are the things to ensure to disable the capture.
