• What job is better for a newbie, one that requires you to create a new program frequently, or something like software maintenance?

  - by MobileDev123

  One of my friends has just completed his college degree and is ready to join the programmers' world. Today he has two offers, one with new projects every time, and another with software maintenance. The remaining factors are not important to him, what he wants to know is which option is better? My experience goes with second option because my first job was the maintenance one and I could learn how my fellow programmers made mistakes while coding . But I soon switched to a new job which required me to create new project every time. I enjoyed both but I must admit that my first job has given me a more advantage today. But it's not necessary that my experience can give benefit to him. But I want to know what is general approach? If I have to give him final verdict on these two, what should I tell him? Edit Everybody deserves one up vote here, I am really learning a lot from you guys.

• Bad idea to display mail server info in public github project?

  - by kentcdodds

  I have the project for work that requires me to send e-mails to people using our work mail server. The server doesn't require authentication. Part of my project is using a Java-Helper I'm developing on GitHub. I don't know if I completely understand how it all works, but I'm guessing it would be a bad idea to have the server information available on GitHub for the world to see. Is this correct? After thought: I'm not going to put it in the Java-Helper because that wouldn't be helpful for anyone but me. but I'm still curious to know the answer to this question :) Thanks!

• How to attach two XNA models together?

  - by jeangil

  I go back on unsolved question I asked about attaching two models together, could you give me some help on this ? For example, If I want to attach together Model1 (= Main model) & Model2 ? I have to get the transformation matrix of Model1 and after get the Bone index on Model1 where I want to attach Model2 and then apply some transformation to attach Model2 to Model1 I wrote some code below about this, but It does not work at all !! (6th line of my code seems to be wrong !?) Model1TransfoMatrix=New Matrix[Model1.Bones.Count]; Index=Model1.bone[x].Index; foreach (ModelMesh mesh in Model2.Meshes) { foreach(BasicEffect effect in mesh.effects) { matrix model2Transform = Matrix.CreateScale(0.1.0f)*Matrix.CreateFromYawPitchRoll(x,y,z); effect.World= model2Transform *Model1TransfoMatrix[Index]; effect.view = camera.View; effect.Projection= camera.Projection; } mesh.draw(); }

• Point Light Soft Shadows

  - by notabene

  How to implement soft shadows for omni directional (point) light. We use typical shadow mapping technique. Depth is rendered to texture cube and addresing is pretty simple then. Just using vector from light to fragments world position. It works perfectly. Until you want soft shadows. In our engine we use PCSS technique for spot lights. But for point light there begins troubles. How to sample in 3D? I developed technique when orthonormal basis is created from a direction and upvector (0,1,0). And then multiply sampling vector (something like this (1.0,i/depthMapSize,j/depthMapSize) with this basis. But this (of course :)) looks pretty bad for vectors near (0,1,0) and (0,-1,0). I will appreciate any help on this.

• Are the famous websites handmade? [closed]

  - by Mithun Chuckraverthy

  I'm a newbie in web designing. I always wanted to build a professional quality website by myself. So, I started learning HTML/XHTML and CSS for presentation; and, JavaScript and PHP/MySQL for scripting. I wonder, would the developers of famous websites design them by hand? Or, have they found out any better idea of using softwares? If so, can you tell me what are they? (By the word famous, I mean any websites that are liked by millions of people all over the world. Like: Google, Facebook etc.) Thanks in advance!

• OpenGL 2D Rasterization Sub-Pixel Translations

  - by Armin Ronacher

  I have a tile based 2D engine where the projection matrix is an orthographic view of the world without any scaling applied. Thus: one pixel texture is drawn on the screen in the same size. That all works well and looks nice but if the camera makes a sub-pixel movement small lines appear between the tiles. I can tell you in advance what does not fix the problem: GL_NEAREST texture interpolation GL_CLAMP_TO_EDGE What does “fix” the problem is anchoring the camera to the nearest pixel instead of doing a sub-pixel translation. I can live with that, but the camera movement becomes jerky. Any ideas how to fix that problem without resorting to the rounding trick I do currently?

• Looking for games in environments similar to a pinball table

  - by chaosTechnician

  I'm on a team of students working on a third-person adventure game that takes place inside a pinball machine (like, small scale, on the surface, avoiding pinballs, etc). One of my responsibilities on the project is to find games that are similar to this concept in appearance and/or gameplay for reference. So, does anyone know of games (other than pinball) that takes place in a pinball-like environment? Or, adventure games that take place in small, cramped environments with multiple paths around the world? Or games in which the player is often bombarded with balls (or other similar unintelligent obstacles)? Or games that take place on a small scale?

• Develop an android and iPhone application with shared database

  - by Bongo

  I have a great idea for smartphone application, And I want to develop an application suited for both android and iPhone. In addition I need to use spatial database for geo indexing that will be shared for both applications. I am new to this app world and I have some questions. Is there away to develop for both machines? I know java but not objective c. My guess is that I need to separate the database from the computing to support both applications. What are the best cloud computing providers with spatial database support that can host the server? Do I need 2 hosting servers or there is one server the can support the both of them? which database provider can support geo indexing and support this intergraion, I prefer providers with reasonable free quotas. Thanks.

• Is it possible to construct a cube with less than 24 vertices

  - by Telanor

  I have a cube-based world like minecraft and I'm wondering if there's a way to construct a cube with less than 24 vertices so I can reduce memory usage. It doesn't seem possible to me for 2 reasons: the normals wouldn't come out right and per-face textures wouldn't work. Is this the case or am I wrong? Maybe there's some fancy new dx11 tech that can help? Edit: Just to clarify, I have 2 requirements: I need surface normals for each cube face in order to do proper lighting and I need a way to address a different indexes in a texture array for each cube face

• Scrolling Box2D DebugDraw

  - by onedayitwillmake

  I'm developing a game using Box2D (javascript implementation - Box2DWeb), and I would like to know how I can pan the debug draw. I know the usual answer is - don't use debug draw, it's just for debugging. I'm not, however not all my objects are on the same screen, and i'd like to see where they are in the physics representation. How can I pan the debug drawing? As you can see the debug draw stuff, is show on the top left, but it only shows a small part of the world. Here is an example of what I mean: http://onedayitwillmake.com/ChuClone/ The game is open source, If you'd like to poke through and note something that perhaps i'm doing something that is obviously wrong: https://github.com/onedayitwillmake/ChuClone

• SEO disasters moving domain for a high traffic website?

  - by chrism2671

  We're looking at moving our website from http://www.wikijob.co.uk to http://www.wikijob.com/uk as we spread our wings internationally. Our .co.uk website has a PR6 and received around 1/2 million visitors a month, 40% international. The wikijob.com domain, while registered for a while, has not been used nor promoted. I am concerned that moving domain could really haemorrhage our traffic and result in a loss of goodwill from Google, even if we use a 301, but equally, if we could transfer that pagerank to the .com domain, that would give us a massive head start around the world. Should we do it, or should we start over with .com and leave .co.uk as is?

• Different ways to pass Textures into HLSL shaders

  - by codymanix

  The GraphicsDevice class of xna 4 has the properties Textures and VertexTextures. What is the exact difference? I don't really understand what MSDN tells me about this. I usually use Effect parameters to pass textures to my HLSL shaders. What are the differences between these methods, which is faster? My Scenario: I am working on a minecraft like game, which means lots of separate DrawPrimitives calls and change current Texture often since I have lots of different block types. Since I use an Octtree to organize the world, I cannot easily sort by texture.

• Is OO-programming really as important as hiring companies place it?

  - by ale

  I am just finishing my masters degree (in computing) and applying for jobs.. I've noticed many companies specifically ask for an understanding of object orientation. Popular interview questions are about inheritance, polymorphism, accessors etc. Is OO really that crucial? I even had an interview for a programming job in C and half the interview was OO. In the real world, developing real applications, is object orientation nearly always used? Are key features like polymorphism used A LOT? I think my question comes from one of my weaknesses.. although I know about OO.. I don't seem to be able to incorporate it a great deal into my programs. I would be really interested to get peoples' thoughts on this!
