• HR According to Batman

  - by D'Arcy Lussier

  Any idea who that guy is running alongside the Caped Crusader? That’s Nightwing, but you may know him as Robin…well, the first Robin anyway. There were actually like 5 Robin’s according to Wikipedia: Dick Grayson, the original, who’s parents were circus performers killed by a gangster. Jason Todd, who was caught trying to steal tires off of the Batmobile. Tim Drake, who saw Dick’s parents die and figured out who Batman and Robin were. and a few others that get into recent time travel/altered reality storylines. What does this have to do with HR? Well, it somewhat ties in with an article by Alex Papadimoulis from 2008. In the article he talks about the “Cravath System”. The Craveth system was developed by a law firm called Cravath, Swaine & Moore back in the 19th century. In a nutshell, they believed in hiring the best and brightest straight out of school. These aspiring lawyers would then begin a fight for survival in the firm, with the strong surviving. In what’s termed the “Up and Out” rule, employees needed to be promoted within 3 years or leave the company. They should achieve partner within 7 – 8 years and no later than 10 after initially coming on board (read all about the system on Wikipedia here). Back to Alex’s article, he quotes from a book published in 1947 about the lawfirm: Under the “Cravath system” of taking a substantial number of men annually and keeping a current constantly moving up in the office, and its philosophy of tenure, men are constantly leaving… it is often difficult to keep the best men long enough to determine whether they shall be made partners, for Cravath-trained men are always in demand, usually at premium salaries. And so we see a pattern forming here: 1. Hire a whole whack of smart college graduates 2. Put them to work 3. The ones that stick around should move up the ladder. The ones that don’t stick around served the company well and left to expound the quality of the Cravath firm. Those that didn’t fall into either of those categories were just let go. There’s some interesting undercurrents to these ideas. If you stick around, you better keep your feet moving! I was at a Microsoft shindig a few months back, and was talking to a Microsoft employee. He shared that at MS you have 5 years to achieve a “senior” position within the company. Once you hit that mark, you can stay there for the rest of your career (he told about a guy who’s a “senior” developer and has been for the last 20+ years working on audio drivers for Windows), but you *must* hit that mark within the timeframe. What we see with Microsoft is Cravath’s system in action, whether intentional or not: bring in smart young people and see which ones stick. You need to give people something to work towards. Saying “You must reach this level or else!” is one way to look at it. The other way is to see achieving a higher rank in the organization as something for ambitious employees to reach towards. It’s important for an organization to always have the next generation of executives waiting in the wings, and unless you’re encouraging that early on you may find yourself in a position of needing to fill positions that nobody has been working towards. Now, you might suggest that this isn’t that big of a deal because you could just hire someone from outside the organization, but the Cravath system holds to the tenet of promoting internally; develop your own talent, since your business is the best place for the future leadership to learn teh business from. It’s OK for people to quit. Alex’s article really drives this point home, but its worth noting here also: its OK for your people to quit. In fact its inevitable…and more inevitable that it’ll be good people that leave. Some will stay and work towards the internal awards of promotion, but a number will get experience, serve the organization well, and then move on to something else. This should be expected and treated as a natural business occurrence. The idea of an alumni of an organization begins to come into play here: “That guy used to work for <insert company here>”. There’s a benefit in that: those best and brightest will be drawn to your organization and your reputation will permeate your market through former staff that are sought after because of how well you nurtured them. The Batman Hook All of this brings us back to Batman and his HR practice: when Dick decided he’d had enough of the Robin schtick, he quit and became his own…but he was always associated with Batman and people understood where his training had come from. To the Dark Knight’s credit, he continued training partners under the Robin brand. Luckily he didn’t have to worry about firing any of them (the ship sort of sails when you reveal a secret identity), although there was that unfortunate “quitting” of the second Robin when the Joker blew him up…but regardless, we see the Cravath system at work: bring in talent, expect great things, and be ok with whatever they decide for their careers. It’s an interesting way to approach HR, and luckily for us our business isn’t as dangerous or over-the-top as the caped crusader’s.

• OpenGL ES 2.0: Using VBOs?

  - by Bunkai.Satori

  OpenGL VBOs (vertex buffer objects) have been developed to improve performance of OpenGL (OpenGL ES 2.0 in my case). The logic is that with the help of VBOs, the data does not need to be copied from client memory to graphics card on per frame basis. However, as I see it, the game scene changes continuously: position of objects change, their scaling and rotating change, they get animated, they explode, they get spawn or disappear. In such highly dynamic environment, such as computer game scene is, what is the point of using VBOs, if the VBOs would need to be constructed on per-frame basis anyway? Can you please help me to understand how to practically take beneif of VBOs in computer games? Can there be more vertex based VBOs (say one per one object) or there must be always exactly only one VBO present for each draw cycle?

• Box2D body rotation with setTransform

  - by thobens

  I' having a problem rotating a body with setTransform(), The body has multiple sensors that should rotate with the player. The rotation works but it rotates around the bodys local 0,0 position instead of the center. Note that the game is in a top-down perspective and the player can go in four different directions, thus I need to rotate him immediately (in one tick) in 90 degrees steps. Up: Down: I can't find a way to set the rotation center. Here's the code I use to rotate it: float angle = direction * 90 * MathUtils.degRad; // direction is an int value from 0 to 3 body.setTransform(body.getPosition(), angle); I also tried body.getLocalCenter().set() and bc.body.getMassData().center.set() but it didn't seem to have any effect. How can I rotate the body around its center?

• How was your experience working as a game tester?

  - by MrDatabase

  I'm currently an independent game developer. I'm open to the idea of working on a team in the game industry. I'm under the impression that being a "game tester" is a relatively easy way to get a job... however that job may be somewhat undesirable. So how was your experience working as a tester in the game industry? Some interesting experiences could include: Did the game tester position lead to other more desirable positions? How were the relationships between testers and developers? Did you write any code? (test "frameworks", unit tests etc) If bugs made it into production was any (potentially unfair) blame put on the testers?

• Time based movement Vs Frame rate based movement?

  - by sil3nt

  Hello there, I'm new to Game programmming and SDL, and I have been following Lazyfoo's SDL tutorials. My question is related to time based motion and frame rate based motion, basically which is better or appropriate depending on situations?. Could you give me an example where each of these methods are used?. Another question I have is that, in lazyfoo's two Motion tutorials (FPS based and time based) The time based method showed a much smoother animation while the Frame rate based one was a little hiccupy, meaning you could clearly see the gap between the previous location of the dot and its current position when you compare the two programs. As beginner which method should I stick to?(all I want is smooth animations).

• Ahk script and C++ communication [closed]

  - by Tony

  I wish to use the fuctions of autohotkey within a C++ program. I am currently running my scripts triggered by the c++ program- I just run them as a .bat file. This works well but the problem is that I cannot return values from the script to the c++ program. I wish to be able to read the position of the mouse from the script and make decisions based upon this in my C++ program. My scripts do quite complex things- so doing this in autohotkey is the best solution for me- I have knowledge of C, but little of C++. I have read about the Autohotkey .DLL - I know how to trigger it but not how to read values from it. If anyone could instruct me or even post example code of a .dll being loaded and a value sent to a script and a value returned- I would be eternally grateful!! I have spent hours on this and to no avail!!

• 3D Dice using Maya - for integration with iOS game app

  - by Anil

  My designer is building a 3D design of a dice using Maya. I want to integrate this in my iOS app so that the user can spin the dice and get a number. Then they play the game using that number. So, I have two questions: 1) How can I make the dice spin and stop at a random position so that a number is presented to the user? and 2) Once it stops spinning how can I detect the number that is displayed to the user (programmatically)? Many thanks. -Anil

• Mixing Objective-C and C++: Game Loop Parts

  - by Peteyslatts

  I'm trying to write all of my game in C++ except for drawing and game loop timing. Those parts are going to be in Objective-C for iOS. Right now, I have ViewController handling the update cycle, but I want to create a GameModel class that ViewController could update. I want GameModel to be in C++. I know how to integrate these two classes. My problem is how to have these two parts interact with the drawing and image loading. GameModel will keep track of a list of children of type GameObject. These GameObjects update every frame, and then need to pass position and visibility data to whatever class or method will handle drawing. I feel like I'm answering my own question now (talking it out helps) but would it be a good idea to put all of the visible game objects into an array at the end of the update method, return it, and use that to update graphics inside ViewController?

• Isometric - precise screen coordinates to isometric

  - by Rawrz

  I'm trying to translate mouse coords to precise isometric coords (I can already find the tile the mouse is over, but I want it to be more precise). I've tried several different methods but I seem to keep falling short. For drawing I use: batch.draw( texture, (y * tileWidth / 2) + (x * tileWidth / 2), (x * tileHeight / 2) - (y * tileHeight / 2)) This is what I currently use for figuring out a tile position: float xt = x + camPosition.x - (ScreenWidth/2) ; float yt = (ScreenHeight) - y + camPosition.y - (ScreenHeight/2); int tileY = Math.round((((xt) / tileWidth) - ((yt) / tileHeight))); int tileX = Math.round((((xt) / tileWidth) + ((yt) / tileHeight))- 1); I'm just wondering how I could update these to allow for more precise coordinates, instead of tile only. EDIT: Following what ccxvii said below, and removing the -1 from tileX, the object follows my mouse just like I had wanted. Just going to re-examine the math and figure out if that change will result in other messes =o

• who are software design engineers?

  - by Sepala

  My question is, who are software design engineers? And, what is the meaning of the following statement (from a software design engineer job ad)? "Application domain knowledge is essential and....." What is application domain? SDLC? My hope is to become a software engineer one day (OK, to be honest, more than that. I need to be a legend), that who do programming (They say this job has no programming). I am following final year of my Bsc(Hons) in computing and I have completed a foreign diploma, majoring software engineering - Java technologies. Will this job experience help me out to get a job in my desired position, which is mentioned above, after the degree? Wikipedia and google never gave a clear straight forward answer!! Please help!

• 3D Ray Casting / Picking

  - by Chris

  Hi, I am not sure if I should post this link, but I feel this falls into game development just as much as it does math. I have a ray cast's far and near values and I am trying to calculate the end point of the ray so that I can either draw a line to show the ray, or render an object at the end of 3d mouse position. Here is my post on the stack overflow math site, if there is a problem with me doing this just close the thread. Thank you. http://math.stackexchange.com/questions/15918/help-with-matrix-mathematica

• GLSL Atmospheric Scattering Issue

  - by mtf1200

  I am attempting to use Sean O'Neil's shaders to accomplish atmospheric scattering. For now I am just using SkyFromSpace and GroundFromSpace. The atmosphere works fine but the planet itself is just a giant dark sphere with a white blotch that follows the camera. I think the problem might rest in the "v3Attenuation" variable as when this is removed the sphere is show (albeit without scattering). Here is the vertex shader.

• Bullet physics debug drawing not working

  - by Krishnabhadra

  Background I am following on from this question, which isn't answered yet. Basically I have a cube and a UVSphere in my scene, with UVSphere on the top of the cube without touching the cube. Both exported from blender. When I run the app The UVSphere does circle around the cube for 3 or 4 times and jump out of the scene. What I actually expect was the sphere to fall on top of the cube. What this question about From the comment to the linked question, I got to know about bullet debug drawing, which helps in debugging by drawing outline of physics bodies which are normally invisible. I did some research on that and came up with the code given below. From whatever I have read, below code should work, but it doesn't.

• Slot Machine Pay Out

  - by Kris.Mitchell

  I have done a lot of research into random number generators for slot machines, reel stop calculations and how to physically give the user a good chance on winning. What I can't figure out is how to properly insure that the machine is going to have a payout rating of (lets say) 95%. So, I have a reel set up wit 22 spaces on it. Filled with 16 different symbols. When I get my random number, mod divide it by 64 and get the remainder, I hop over to a loop up table to see how the virtual stop relates to the reel position. Now that I have how the reels are going to stop, do I make sure the payout ratio is correct? For every dollar they put in, how to I make sure the machine will pay out .95 cents? Thanks for the ideas. I am working in actionscript, if that helps with the language issues, but in general I am just looking for theory.

• DirectX9 dynamic rendering

  - by gardian06

  What I am planning to do is have the models (or maybe just an identifier for the model to be used) stored outside of the directX9 framework, and so in nature have completely dynamic rendering. All of the information that I have found contains static rendering (rendering models that are stored in memory at specific positions) I would like information on how to take a model (or identifier for a model type) that is stored outside of the framework, and render it to the screen. I am expected to take a container that holds all the relevant data to be rendered. The information outside would hold the position, orientation (quaternion, though I am told that I can also get a rotation matrix if I prefer), and dimensions (scale)

• What's the deal with URLs for Yandex.Metrica not prepended with "http"?

  - by sharptooth

  The description of Yandex.Metrica explicitly says that URLs like //mc.yandex.ru/metrika/watch.js (no http: in front) that the web site owner has to insert into his pages are not erroneous. So for example this code: <img src="//mc.yandex.ru/watch/00000" style="position:absolute; left:-9999px;" alt="" /> is claimed to be okay. However the code validator thinks such URLs are not okay and I'd rather make the validator happy so that noone breaks the code later trying to "fix" it. Why are these URLs not prepended with http:? What happens if I actually prepend them with http:?

  Hi, I know some people have asked about getting back into programming after a break and this is a potential duplicate. I just am in a position where I can go back to school in Stat/Applied Math. But I'm very worried about the impact it will have on my career and ability to find a job afterwards. I have 3 years experience in .NET on top of a couple of years in PHP. Right now, I'm a senior software engineer. Do you think taking two years off to do math is going to dramatically hurt my marketability?
