• FPS camera specification

  - by user1095108

  I remember I once composed a FPS viewing transformation, as a composition of 3 rotations, each with an angle as a parameter. The first angle specified the left/right rotation around the y-axis, the second angle the up/down rotation around the x-axis, and the third around the z-axis. The viewing transformation was therefore specified by 3 angles. Naturally, this transformation had a gimbal lock, depending in what order the transformation were performed. What should I look at to derive my viewing transformation without the gimbal lock? I know the "lookAt" method already, but I consider that cumbersome. EDIT: MY first guess is to do the first 2 transformations to get a viewing direction and then the axis-angle rotation on this axis.

• enable all touchpad functions

  - by user118136

  When I had been using Windows 8 my touchpad had multiple gestures: 2 fingers direction top-bottom = vertical revers scrolling(if I scrolled top than page have scrolled bottom); 2 finger direction left-right = horizontal revers scrolling zoom in and zoom out like smartphones with 2 fingers 2 finger rotation = rotate image in image viewer (+ 90 deg or -90 deg) place a finger in the left edge and drag it to right = change windows application, in Ubuntu I want to change the active program to left like Ctrl+Shift+Tab place a finger in the right edge and drag it to left = open right menu and select the option moving finger on direction top-bottom, in Ubuntu I want to change the active program to right like Alt+Tab I succeed enable 2 finger vertical scrolling of System Setings, but I want that it do not work in revers sense. Do it exist a method to enable the rest of gestures and revers the vertical scrolling? edit: It's a Synaptics touchpad.

• XNA GameTime TotalGameTime slower than real time

  - by robasaurus

  I have set-up an empty test project consisting of a System.Diagnostics.Stopwatch and this in the draw method: spriteBatch.DrawString(font, gameTime.TotalGameTime.TotalSeconds.ToString(), new Vector2(100, 100), Color.White); spriteBatch.DrawString(font, stopwatch.Elapsed.TotalSeconds.ToString(), new Vector2(100, 200), Color.White); The GameTime.TotalGameTime displayed is slower than the stop watch (by about 5 seconds per minute) even though GameTime.IsRunningSlowly is always false, why is this? The reason this is an issue is because I have a server which uses stopwatch and it is faster than my client game. For instance my client notifies the server it has dropped a mine which explodes in one minute. Because the stopwatch is faster the server state explodes the mine before the client and they are out of sync. I don't want to have to notify the client when the server explodes it as this would use unnecessary bandwidth.

• What options are there for splitting UI layout from code logic using a markup language?

  - by Daenyth

  What tools similar to GWT's UIBinder exist in other languages? By this I mean a system where you can define your UI layout in a markup language (preferably html+css) and attach the functionality to the layout using the code. I'm most interested in anything for python, but answers in other languages would interest me as well. I'm interested because the benefits of having a non-programmer work directly on the layout without needing to touch the code and adjust a bunch of UI toolkit method calls is very productive. I'm aware of Flex for flash, but is there anything else out there? What search terms might I use to find such frameworks? I've looked around but I haven't found anything concrete.

• Lining things up while using columns

  - by Charles

  I have a request that may not be possible. I'd like to line up the elements of a form so that the inputs all start at the same place: Name: [ ] Company: [ ] Some question with a long name: [ ] But my list is (somewhat) long and I would like to show them in multiple columns on screens that are wide enough. Ideally, I'd find a POSH method (table-free is semantically appropriate, I think) that works on a reasonable number of browsers. My current page uses a table. I tried CSS with columns: auto; -moz-column-count: auto; -moz-column-width: auto; -webkit-column-count: auto; -webkit-column-width: auto; but Firefox (at least) won't break a table across columns.

• OutOfBounds Exception when creating a PolygonShape using jbox2d

  - by B3nGr33ni3r

  So here's the deal, i'm parsing a file that contains the vertices for a polygon, that i want to create in box2d. I create a new PolygonShape() and then call .set() giving it a defined array of Vec, and that defined array's .length property. I expected this to work, since the documentation for jbox2d says this method takes a Vec array, and the count of Vec objects in that array. However, it errors out, and it seems to be unrelated to my code. The error i get is Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 8 at org.jbox2d.collision.shapes.PolygonShape.set(PolygonShape.java:174) and, upon looking at that line in the jbox2d svn repository, i still cannot figure out the issue. Any help is appreciated!

• Predicted target location

  - by user3256944

  I'm having an issue with calculating the predicted linear angle a projectile needs to move in to intersect a moving enemy ship for my 2D game. I've tried following the document here, but what I've have come up with is simply awful. protected Vector2 GetPredictedPosition(float angleToEnemy, ShipCompartment origin, ShipCompartment target) { // Below obviously won't compile (document wants a Vector, not sure how to get that from a single float?) Vector2 velocity = target.Thrust - 25f; // Closing velocity (25 is example projectile velocity) Vector2 distance = target.Position - origin.Position; // Range to close double time = distance.Length() / velocity.Length(); // Time // Garbage code, doesn't compile, this method is incorrect return target.Position + (target.Thrust * time); } I would be grateful if the community can help point out how this is done correctly.

• How to smartly optimize ads on website

  - by YardenST

  I've a content website that presents ads. Now, my team want to optimize it for a better experience for the users. (we really believe our ads are good for our users.) We are sure that every website deals with this issue and there must be some known ways and methods to deal with it, that smart people thought of before. so what i'm looking is a tested, working method to optimize ads. for example: if i was asking about optimizing my website in Google, I would expect you to answer me: learn SEO if i was asking about optimizing the use of my website: usability testing. navigation: information architecture what is the field that deals with optimizing ads?

• Is there a language offering LISP-like macros with a more complex syntax?

  - by blubb

  LISP's macros are extremely powerful constructs, and the inability to introspect and modify the program itself beyond the method signature level has always struck me as a limitation. Yet I favour "complex" syntax because it tends to be closer to natural language. So far I have failed to find a language which combines a powerful macro mechanism such as LISP's with a naturally looking syntax (1). Is anyone aware of such a language? Footnote: I would consider python to have a naturally looking syntax as it allows constructs like this: if 0 < a < 5 and b in list. The avoidance of braces to structure blocks is irrelevant in this case, though.

• Isn't class scope purely for organization?

  - by Di-0xide

  Isn't scope just a way to organize classes, preventing outside code from accessing certain things you don't want accessed? More specifically, is there any functional gain to having public, protected, or private-scoped methods? Is there any advantage to classifying method/property scope rather than to, say, just public-ize everything? My presumption says no simply because, in binary code, there is no sense of scope (other than r/w/e, which isn't really scope at all, but rather global permissions for a block of memory). Is this correct? What about in languages like Java and C#[.NET]?

• Is it okay to have many Abstract classes in your application?

  - by JoseK

  We initially wanted to implement a Strategy pattern with varying implementations of the methods in a commmon interface. These will get picked up at runtime based on user inputs. As it's turned out, we're having Abstract classes implementing 3 - 5 common methods and only one method left for a varying implementation i.e. the Strategy. Update: By many abstract classes I mean there are 6 different high level functionalities i.e. 6 packages , and each has it's Interface + AbstractImpl + (series of Actual Impl). Is this a bad design in any way? Any negative views in terms of later extensibility - I'm preparing for a code/design review with seniors.

• Disqus thread migration. Gotchas?

  - by sramsay

  I've been migrating a site to a new domain. The site itself is pretty straightforward (it uses Jekyll), and everything has gone fine -- except migration of Disqus threads. I've had partial success -- some of the threads have migrated successfully, but not all. I've tried the domain migration wizard (which caught a few), the URL mapper (which caught a few), and the 301 redirect crawler (which caught a few). But the remaining threads just won't move, no matter which method I use. So, I suppose I suppose I'm asking if there are any "gotchas" I should know about with this. When you execute any of these migration tools, it says it will "take awhile." Does that mean hours? Days? I can't tell if it's working, and there's no logging or error reporting that I can see.

• Cannot upgrade or install 12.04 - Black screen

  - by Paul

  An update from 11.10 to 12.04 failed because of a boot into black screen (Nvidia graphics card) after selecting normal boot in Grub (recovery console was available though). I then wiped the whole partition (deleting all proprietary drivers) and tried a fresh install, but could not run the installation cd because it was booting straight into a black screen again. Now I reinstalled 11.10 (and installed proprietary Nvidia driver version 173), and would like to ask 2 questions: 1 - Is there a proven method to fix this problem from the recovery console, so that I can safely try upgrading again (without much knowledge of Ubuntu)? 2 - Is there a website which I could check for updated Nvidia drivers packaged into the upgrade, so that I can safely upgrade without running into a black screen some time later on?

• Gnome Shell installed not working in Ubuntu 12.04

  - by user68180

  I had Gnome Shell working perfectly on my desktop, and I tried to install it on my laptop by the exact same method, (tried apt-get, synaptic and software centre), but it won't work. It seems to install fine with no errors. If I select "Gnome" at login, I get the "Gnome Classic" interface rather than Gnome Shell. My laptop has sufficient specs to run Gnome Shell. Am I missing something? EDIT: I have just discovered that under System Details Graphics, it says "Unknown". So, Ubuntu hasn't recognised my graphics card, and I'm guessing this is why Gnome Shell can't work. I have a nVidia GeForce GT 525M. How can I get it working? (as you may have realised, I'm a linux noob)

• Asking potential developers to draw UML diagrams during the interview

  - by DotnetDude

  Our interview process currently consists of several coding questions, technical questions and experiences at their current and previous jobs. Coding questions are typically a single method that does something (Think of it as fizzbuzz or reverse a string kind of question) We are planning on introducing an additional step where we give them a business problem and ask them to draw a flowchart, activity, class or a sequence diagram. We feel that our current interview process does not let us evaluate the candidate's thinking at a higher level (which is relevant for architect/senior level positions). To give you some context, we are a mid size software company with around 30 developers in the team. If you have this step in your interview process, how has it improved your interviewing veracity? If not, what else has helped you evaluate the candidates better from a technical perspective.

• Visitor-pattern vs inheritance for rendering

  - by akaltar

  I have a game engine that currently uses inheritance to provide a generic interface to do rendering: class renderable { public: void render(); }; Each class calls the gl_* functions itself, this makes the code hard to optimize and hard to implement something like setting the quality of rendering: class sphere : public renderable { public: void render() { glDrawElements(...); } }; I was thinking about implementing a system where I would create a Renderer class that would render my objects: class sphere { void render( renderer* r ) { r->renderme( *this ); } }; class renderer { renderme( sphere& sphere ) { // magically get render resources here // magically render a sphere here } }; My main problem is where should I store the VBOs and where should I Create them when using this method? Should I even use this approach or stick to the current one, perhaps something else? PS: I already asked this question on SO but got no proper answers.

• Permissions depending on parameters passed to application

  - by Engineiro

  I have a java app that writes to a very important table I have. This is sudo protected, but this app takes a parameters for where the output should go. The default is the REAL DEAL but the "output" parameter takes priority over the default, so if a user provides a path that they have write permission for, say: /home/username/mystuff then I would like for users to be allowed to write to these directories. The app is launched in a shell script, so I am wondering if I can check that the string does not equal /path/to/real/deal and not empty (since /path/to/real/deal is the default) and allow users to write to places they have permissions for. My impression of linux permissions is that it is tied to the application itself and cannot be conditionally approved, but I wonder if there is some bash fu or alternative method I can perform to get me my desired result. Using Ubuntu 10.04.4 LTS

• Java ResourceLoader.getResourceAsStream local resource

  - by Dajgoro Labinac

  Before using lwjgl, i used the Graphic method, and there i displayed imageicons, and i had the picture file located in the resources. I used: ImageIcon tcard = new ImageIcon(this.getClass().getResource("RCA.png")); to load the image. Now when i load textures in lwjgl, i have to use absolute paths to locate the file: tcard = TextureLoader.getTexture("PNG", ResourceLoader.getResourceAsStream("C:/RCA.png")); I tried googling, but i didn't find anything helpful... How can i load the image from the local resources like in the first example?

• Interviews that include Algorithms and Data Structures

  - by EricFromSouthPark

  I want to start looking for jobs in great companies and I have four years of enterprise corporations development, three years with C#.NET and alomst one year with Ruby On Rails, JS, etc... But when I look up interview questions from Google, Amazon, Fog Creek, DropBox, etc... they are really targeted at students that are coming fresh out of college and still remember what was Dynamic Programming and Dijkstra algorithms ... but I don't! :( It has been a while for me ... If a I need a sort algorithm I would either Google it or there already is a library and method that does it for me. So what should I do? Do they realize that this guy is not coming from college and will ask more general questions about software architecture or nop! I should go back find my old Data structures book from the storage and read them? In that case wht books and language do you recommend to hone my skills?

• Updating "Inactive" Chunks

  - by Conner Bryan

  In my game, the only chunks (4x4 areas of tiles) in memory are the ones that the player is in. However, chunks need to have updates applied to them over time. A (likely) well-known example would be MineCraft: even if the player isn't in a chunk, the wheat still needs to grow over time. My current solution is to call a method and pass in the time since the chunk was active.. but what if the chunk depends on nearby chunks for information, i.e. vines spreading or similar? Is there any reasonable solutions to this problem, or should I simply not depend on nearby chunks?

  I have a server that has 4 hds inside all in stadalone configurations (no hardware raid). I want using preseed to create a "regular" partition on disk1 on which i ll install ubuntu and create a raid 0 array with the remainning three disks. Is this possible? Can i use partman-auto/method twice inside the preseed file once for regular and once for raid? I need to use this for unattended provisioning so i need to set my disks inside the preseed file. Thanking you all in advance for your time. Costas

• How should UI layer pass user input to BL layer?

  - by BornToCode

  I'm building an n-tier application, I have UI, BL, DAL & Entities (built from POCO) projects. (All projects have a reference to the Entities). My question is - how should I pass user input from the UI to the BL, as a bunch of strings passed to the BL method and the BL will build the object from the parameters, or should I build the objects inside the UI submit_function and send objects as parameters? EDIT: I wrote n-tier application, but what I actually meant was just layers.

• How to store and update data table on client side (iOS MMO)

  - by farseer2012

  Currently i'm developing an iOS MMO game with cocos2d-x, that game depends on many data tables(excel file) given by the designers. These tables contain data like how much gold/crystal will be cost when upgrade a building(barracks, laboratory etc..). We have about 10 tables, each have about 50 rows of data. My question is how to store those tables on client side and how to update them once they have been modified on server side? My opinion: use Sqlite to store data on client side, the server will parse the excel files and send the data to client with JSON format, then the client parse the JOSN string and save it to Sqlite file. Is there any better method? I find that some game stores csv files on client side, how do they update the files? Could server send a whole file directly to client?

• Will my game engine be compatible with physics engines?

  - by Bane

  My engine supports Scene handling, Cameras, and has a Renderer. Also, it has a class called Drawable, which has the position, the shape and the picture of an object. The picture property has width, height, rotation and a draw method. All game objects are supposed to inherit from this Drawable class, and are added to the Scene, along with a Map (collection of Tiles, that also inherit from Drawable), lights, and so on and so forth. The shape property of a Drawable is a Polygon, a collection of user defined vertices around the position of a Drawable (this is a relative coordinate system, so [0, 0] is the position of the Drawable. With this setup, will the users of my engine (probably only me) still be able to intergrate physics engines such as Box2DJS into their games?
