  • Programming concepts taken from the arts and humanities

    - by Joey Adams
    After reading Paul Graham's essay Hackers and Painters and Joel Spolsky's Advice for Computer Science College Students, I think I've finally gotten it through my thick skull that I should not be loath to work hard in academic courses that aren't "programming" or "computer science" courses. To quote the former: I've found that the best sources of ideas are not the other fields that have the word "computer" in their names, but the other fields inhabited by makers. Painting has been a much richer source of ideas than the theory of computation. — Paul Graham, "Hackers and Painters" There are certainly other, much stronger reasons to work hard in the "boring" classes. However, it'd also be neat to know that these classes may someday inspire me in programming. My question is: what are some specific examples where ideas from literature, art, humanities, philosophy, and other fields made their way into programming? In particular, ideas that weren't obviously applied the way they were meant to (like most math and domain-specific knowledge), but instead gave utterance or inspiration to a program's design and choice of names. Good examples: The term endian comes from Gulliver's Travels by Tom Swift (see here), where it refers to the trivial matter of which side people crack open their eggs. The terms journal and transaction refer to nearly identical concepts in both filesystem design and double-entry bookkeeping (financial accounting). mkfs.ext2 even says: Writing superblocks and filesystem accounting information: done Off-topic: Learning to write English well is important, as it enables a programmer to document and evangelize his/her software, as well as appear competent to other programmers online. Trigonometry is used in 2D and 3D games to implement rotation and direction aspects. Knowing finance will come in handy if you want to write an accounting package. Knowing XYZ will come in handy if you want to write an XYZ package. Arguably on-topic: The Monad class in Haskell is based on a concept by the same name from category theory. Actually, Monads in Haskell are monads in the category of Haskell types and functions. Whatever that means...

    - by douglasscott
    Working for a big company I enjoy all the Microsoft tools I can consume. I also have the infrastructure to support my development and team communication.I recently helped form a small consulting team that requires the same type of resources. That is when the realization of the true cost of Microsoft's professional development tools really hit me.Okay, I'll just bite the bullet and get what I'm used to working with to do high quality development projects.  After just a few minutes of looking at street prices and doing some quick math I began to have a realization...doing this right isn't cheap!Luckily there is help.  If you are willing to get your ducks in a row and do a little documentation  Microsoft will give you some developer manna. I went to the Bizspark site and completed the application which describes your company profile and services offer.  The approval process took about a week.  Voila, A Visual Studio Ultimate with MSDN Subscription!As a start-up Office 365 can be a great solution for all your team communications.  I also enrolled in the Microsoft Cloud Essentials program as part of a business track.  Once you meet the Cloud Essentials requirements you will receive 250 Office 365 licenses! This includes Office and hosted Exchange, Lync, and SharePoint.Take advantage of what Microsoft has to offer for your start-up.  It just may surprise you and save you a lot of your start-up budget.

  • Geek it Up

    - by BuckWoody
    I’ve run into a couple of kinds of folks in IT. Some really like technology a lot – a whole lot –and others treat it more as a job. For those of you in the second camp, you can go back to your drab, meaningless jobs – this post is for the first group. I’m a geek. Not a little bit of a geek, a really big one. I love technology, I get excited about science and electronics in general, and I read math books when I don’t have to. Yes, I have a Star Trek item or two around the house. My daughter is fluent in both Monty Python AND Serenity. I totally admit it. So if you’re like me (OK, maybe a little less geeky than that), then go for it. Put those toys in your cubicle, wear your fan shirt, but most of all, geek up your tools. No, this isn’t an April Fool’s post – I really mean it. I’ve noticed that when I get the larger monitor, better mouse, cooler keyboard, I LIKE coming to work. It’s a way to reward yourself – I’ve even found that it makes work easier if I have the kind of things I enjoy around to work with. So buy that old “clicky” IBM keyboard, get three monitors, and buy a nice headset so that you can set all of your sounds to Monty Python WAV’s. And get to work.

  • Teaching high school kids ASP.NET programming

    - by dotneteer
    During the 2011 Microsoft MVP Global Summit, I have been talking to people about teaching kids ASP.NET programming. I want to work with volunteer organizations to provide kids volunteer opportunities while learning technical skills that can be applied elsewhere. The goal is to teach motivated kids enough skill to be productive with no more than 6 hours of instruction. Based on my prior teaching experience of college extension courses and involvement with high school math and science competitions, I think this is quite doable with classic ASP but a challenge with ASP.NET. I don’t want to use ASP because it does not provide a good path into the future. After some considerations, I think this is possible with ASP.NET and here are my thoughts: · Create a framework within ASP.NET for kids programming. · Use existing editor. No extra compiler and intelligence work needed. · Using a subset of C# like a scripting language. Teaches data type, expression, statements, if/for/while/switch blocks and functions. Use existing classes but no class creation and OOP. · Linear rendering model. No complicated life cycle. · Bare-metal html with some MVC style helpers for widget creation; ASP.NET control is optional. I want to teach kids to understand something and avoid black boxes as much as possible. · Use SQL for CRUD with a helper class. Again, I want to teach understanding rather than black boxes. · Provide a template to encourage clean separation of concern. · Provide a conversion utility to convert the code that uses template to ASP.NET MVC. This will allow kids with AP Computer Science knowledge to step up to ASP.NET MVC. Let me know if you have thoughts or can help.

  • Inverted textures

    - by brainydexter
    I'm trying to draw textures aligned with this physics body whose coordinate system's origin is at the center of the screen. (XNA)Spritebatch has its default origin set to top-left corner. I got the textures to be positioned correctly, but I noticed my textures are vertically inverted. That is, an arrow texture pointing Up , when rendered points down. I'm not sure where I am going wrong with the math. My approach is to convert everything in physic's meter units and draw accordingly. Matrix proj = Matrix.CreateOrthographic(scale * graphics.GraphicsDevice.Viewport.AspectRatio, scale, 0, 1); Matrix view = Matrix.Identity; effect.World = Matrix.Identity; effect.View = view; effect.Projection = proj; effect.TextureEnabled = true; effect.VertexColorEnabled = true; effect.Techniques[0].Passes[0].Apply(); SpriteBatch.Begin(SpriteSortMode.BackToFront, BlendState.AlphaBlend, null, DepthStencilState.Default, RasterizerState.CullNone, effect); m_Paddles[1].Draw(gameTime); SpriteBatch.End(); where Paddle::Draw looks like: SpriteBatch.Draw(paddleTexture, mBody.Position, null, Color.White, 0f, new Vector2(16f, 16f), // origin of the texture 0.1875f, SpriteEffects.None, // width of box is 3*2 = 6 meters. texture is 32 pixels wide. to make it 6 meters wide in world space: 6/32 = 0.1875f 0); The orthographic projection matrix seem fine to me, but I am obviously doing something wrong somewhere! Can someone please help me figure out what am i doing wrong here ? Thanks

  • Screen space to world space

    - by user13414
    I am writing a 2D game where my game world has x axis running left to right, y axis running top to bottom, and z axis out of the screen: Whilst my game world is top-down, the game is rendered on a slight tilt: I'm working on projecting from world space to screen space, and vice-versa. I have the former working as follows: var viewport = new Viewport(0, 0, this.ScreenWidth, this.ScreenHeight); var screenPoint = viewport.Project(worldPoint.NegateY(), this.ProjectionMatrix, this.ViewMatrix, this.WorldMatrix); The NegateY() extension method does exactly what it sounds like, since XNA's y axis runs bottom to top instead of top to bottom. The screenshot above shows this all working. Basically, I have a bunch of points in 3D space that I then render in screen space. I can modify camera properties in real time and see it animate to the new position. Obviously my actual game will use sprites rather than points and the camera position will be fixed, but I'm just trying to get all the math in place before getting to that. Now, I am trying to convert back the other way. That is, given an x and y point in screen space above, determine the corresponding point in world space. So if I point the cursor at, say, the bottom-left of the green trapezoid, I want to get a world space reading of (0, 480). The z coordinate is irrelevant. Or, rather, the z coordinate will always be zero when mapping back to world space. Essentially, I want to implement this method signature: public Vector2 ScreenPointToWorld(Vector2 point) I've tried several things to get this working but am just having no luck. My latest thinking is that I need to call Viewport.Unproject twice with differing near/far z values, calculate the resultant Ray, normalize it, then calculate the intersection of the Ray with a Plane that basically represents ground-level of my world. However, I got stuck on the last step and wasn't sure whether I was over-complicating things. Can anyone point me in the right direction on how to achieve this?

  • Python or Ruby for freelance?

    - by Sophia
    Hello, I'm Sophia. I have an interest in self-learning either Python, or Ruby. The primary reason for my interest is to make my life more stable by having freelance work = $. It seems that programming offers a way for me to escape my condition of poverty (I'm on the edge of homelessness right now) while at the same time making it possible for me to go to uni. I intend on being a math/philosophy major. I have messed with Python a little bit in the past, but it didn't click super well. The people who say I should choose Python say as much because it is considered a good first language/teaching language, and that it is general-purpose. The people who say I should choose Ruby point out that I'm a very right-brained thinker, and having multiple ways to do something will make it much easier for me to write good code. So, basically, I'm starting this thread as a dialog with people who know more than I do, as an attempt to make the decision. :-) I've thought about asking this in stackoverflow, but they're much more strict about closing threads than here, and I'm sort of worried my thread will be closed. :/ TL;DR Python or Ruby for freelance work opportunities ($) as a first language? Additional question (if anyone cares to answer): I have a personal feeling that if I devote myself to learning, I'd be worth hiring for a project in about 8 weeks of work. I base this on a conservative estimate of my intellectual capacities, as well as possessing motivation to improve my life. Is my estimate necessarily inaccurate? random tidbit: I'm in Portland, OR I'll answer questions that are asked of me, if I can help the accuracy and insight contained within the dialog.

  • Fibonacci numbers in F#

    - by BobPalmer
    As you may have gathered from some of my previous posts, I've been spending some quality time at Project Euler.  Normally I do my solutions in C#, but since I have also started learning F#, it only made sense to switch over to F# to get my math coding fix. This week's post is just a small snippet - spefically, a simple function to return a fibonacci number given it's place in the sequence.  One popular example uses recursion: let rec fib n = if n < 2 then 1 else fib (n-2) + fib(n-1) While this is certainly elegant, the recursion is absolutely brutal on performance.  So I decided to spend a little time, and find an option that achieved the same functionality, but used a recursive function.  And since this is F#, I wanted to make sure I did it without the use of any mutable variables. Here's the solution I came up with: let rec fib n1 n2 c =    if c = 1 then        n2    else        fib n2 (n1+n2) (c-1);;let GetFib num =    (fib 1 1 num);;printfn "%A" (GetFib 1000);; Essentially, this function works through the sequence moving forward, passing the two most recent numbers and a counter to the recursive calls until it has achieved the desired number of iterations.  At that point, it returns the latest fibonacci number. Enjoy!

  • 2D soft-body physics engines?

    - by Griffin
    Hi so i've recently learned the SFML graphics library and would like to use or make a non-rigid body 2D physics system to use with it. I have three questions: The definition of rigid body in Box2d is A chunk of matter that is so strong that the distance between any two bits of matter on the chunk is completely constant. And this is exactly what i don't want as i would like to make elastic, deformable, breakable, and re-connection bodies. 1. Are there any simple 2D physics engines, but with these kinds of characteristics out there? preferably free or opensource? 2. If not could i use box2d and work off of it to create it even if it's based on rigid bodies? 3. Finally, if there is a simple physics engine like this, should i go through with the proccess of creating a new one anyway, simply for experience and to enhance physics math knowledge? I feel like it would help if i ever wanted to modify the code of an existing engine, or create a game with really unique physics. Thanks!

  • Why i can not load a simple pixel shader effect (. fx) file in xna?

    - by Mehdi Bugnard
    I just want to load a simple *.fx file into my project to make a (pixel shader) effect. But whenever I try to compile my project, I get the following error in visual studio Error List: Errors compiling .. ID3DXEffectCompiler: There were no techniques ID3DXEffectCompiler: Compilation failed I already searched on google and found many people with the same problem. And I realized that it was a problem of encoding. With the return lines unrecognized '\ n' . I tried to copy and paste to notepad and save as with ASCII or UTF8 encoding. But the result is always the same. Do you have an idea please ? Thanks a looot :-) Here is my [.fx] file : sampler BaseTexture : register(s0); sampler MaskTexture : register(s1) { addressU = Clamp; addressV = Clamp; }; //All of these variables are pixel values //Feel free to replace with float2 variables float MaskLocationX; float MaskLocationY; float MaskWidth; float MaskHeight; float BaseTextureLocationX; //This is where your texture is to be drawn float BaseTextureLocationY; //texCoord is different, it is the current pixel float BaseTextureWidth; float BaseTextureHeight; float4 main(float2 texCoord : TEXCOORD0) : COLOR0 { //We need to calculate where in terms of percentage to sample from the MaskTexture float maskPixelX = texCoord.x * BaseTextureWidth + BaseTextureLocationX; float maskPixelY = texCoord.y * BaseTextureHeight + BaseTextureLocationY; float2 maskCoord = float2((maskPixelX - MaskLocationX) / MaskWidth, (maskPixelY - MaskLocationY) / MaskHeight); float4 bitMask = tex2D(MaskTexture, maskCoord); float4 tex = tex2D(BaseTexture, texCoord); //It is a good idea to avoid conditional statements in a pixel shader if you can use math instead. return tex * (bitMask.a); //Alternate calculation to invert the mask, you could make this a parameter too if you wanted //return tex * (1.0 - bitMask.a); }

  • Converting world space coordinate to screen space coordinate and getting incorrect range of values

    I'm attempting to convert from world space coordinates to screen space coordinates. I have the following code to transform my object position Vector3 screenSpacePoint = Vector3.Transform(object.WorldPosition, camera.ViewProjectionMatrix); The value does not appear to be in screen space coordinates and is not limited to a [-1, 1] range.

  • Great Debugging skills weak problem solving

    - by Mahmoud
    For the 5 years I worked for various companies, I worked in large software like computer vision kits, embedded, games. I found myself very good at debuggins skills, I've even found and fixed bugs in frameworks and I solved them. The problem is that I'm very weak at problem solving. I got interview with Qualcomm, and they said you're fine at software, but you have a limited problem solving, I also had the same results with Google. I'm very bad at solving puzzles and brain teasers. During the interviews I solve all of the software related problems on the blackboard, but when I went to the GM and face math problems and probabilities, I struggle. How can I improve my problem solving skills? Edit Some of the problems: A cake that is cut from anywhere and needs just one cut to halved in equal. I told him cut it horizontally, he said No, consider it as a 2D Problem!. Consider a concenteric 3 circles, each one can get a color, but not matched with the other circle, how many blobs you can make out of those circles ? this was with the GM ( Augmented Reality SDK) Consider a train, an infinite one, and you looked at the window, and there are two cars, one big, and one small, what is the probability of having only a big car, I said 50%, he said, what if that two cars you dont know their length, and you want to get the probability of getting the biggest one, I struggled, didn't solve it... I was really exahusted after long day of interviews prob of having a number divisible by 5 in numbers from 1 to 100.. struggled!! All coding questions I solved them like reverse a string, detect a cycle in a linked list,..etc.

  • Computer Science Degrees and Real-World Experience

    - by Steven Elliott Jr
    Recently, at a family reunion-type event I was asked by a high school student how important it is to get a computer science degree in order to get a job as a programmer in lieu of actual programming experience. The kid has been working with Python and the Blender project as he's into making games and the like; it sounds like he has some decent programming chops. Now, as someone that has gone through a computer science degree my initial response to this question is to say, "You absolutely MUST get a computer science degree in order to get a job as a programmer!" However, as I thought about this I was unsure as to whether my initial reaction was due in part to my own suffering as a CS student or because I feel that this is actually the case. Now, for me, I can say that I rarely use anything that I learned in college, in terms of the extremely hard math, algorithms, etc, etc. but I did come away with a decent attitude and the willingness to work through tough problems. I just don't know what to tell this kid; I feel like I should tell him to do the CS degree but I have hired so many programmers that majored in things like English, Philosophy, and other liberal arts-type degrees, even some that never went to college. In fact my best developer, falls into this latter category. He got started writing software for his church or something and then it took off into a passion. So, while I know this is one of those juicy potential down vote questions, I am just curious as to what everyone else thinks about this topic. Would you tell a high school kid about this? Perhaps if he/she already knows a good deal of programming and loves it he doesn't need a CS degree and could expand his horizons with a liberal arts degree. I know one of the creators of the Django web framework was a American Literature major and he is obviously a pretty gifted developer. Anyway, thanks for the consideration.

  • Life and Career guidance

    - by Andrei TheGiant Haxtor
    Hello programmers. I have a current dilemma I'm pondering over. I will be graduating from high school with ~60 credits worth of community college work (pre-engineering courses), and I am wondering what would experienced programmers suggest I do with my time since I have all of the bull courses out of the way. Should I start taking computer science/engineering courses or should I take some other courses that interest me?(psych, math) The reason I am asking this is, well , I like doing a lot of self studying, especially relating to software and tech. I don't like to have the pressure of hard classes on me, so I could make up for the time lost doing the CC courses and dive deep in programming and books. I've started getting into programming recently unfortunately, since I didn't have much time b/c of my course load. Right now I am doing Java and messing around with android. I would like to get involved in web&mobile development, operating systems, and finance software. If any of you experienced people could please give me some guidance and words of wisdom, I would greatly appreciated. Sorry that this isn't necessarily related to programming. All the best.

  • How do I apply different probability factors in an algorithm for a cricket simulation game?

    - by Komal Sharma
    I am trying to write the algorithm for a cricket simulation game which generates runs on each ball between 0 to 6. The run rate or runs generated changes when these factors come into play like skill of the batsman, skill of the bowler, target to be chased. Wickets left. If the batsman is skilled more runs will be generated. There will be a mode of play of the batsman aggressive, normal, defensive. If he plays aggressive chances of getting out will be more. If the chasing target is more the run rate should be more. If the overs are final the run rate should be more. I am using java random number function for this. The code so far I've written is public class Cricket { public static void main(String args[]) { int totalRuns=0; //i is the balls bowled for (int i = 1; i <= 60 ; i++) { int RunsPerBall = (int)(Math.random()*6); //System.out.println(Random); totalRuns=totalRuns+RunsPerBall; } System.out.println(totalRuns); } } Can somebody help me how to apply the factors in the code. I believe probability will be used with this. I am not clear how to apply the probability of the factors stated above in the code.

  • Panning with the OpenGL Camera / View Matrix

    - by Pris
    I'm gonna try this again I've been trying to setup a simple camera class with OpenGL but I'm completely lost and I've made zero progress creating anything useful. I'm using modern OpenGL and the glm library for matrix math. To get the most basic thing I can think of down, I'd like to pan an arbitrarily positioned camera around. That means move it along its own Up and Side axes. Here's a picture of a randomly positioned camera looking at an object: It should be clear what the Up (Green) and Side (Red) vectors on the camera are. Even though the picture shows otherwise, assume that the Model matrix is just the identity matrix. Here's what I do to try and get it to work: Step 1: Create my View/Camera matrix (going to refer to it as the View matrix from now on) using glm::lookAt(). Step 2: Capture mouse X and Y positions. Step 3: Create a translation matrix mapping changes in the X mouse position to the camera's Side vector, and mapping changes in the Y mouse position to the camera's Up vector. I get the Side vector from the first column of the View matrix. I get the Up vector from the second column of the View matrix. Step 4: Apply the translation: viewMatrix = glm::translate(viewMatrix,translationVector); But this doesn't work. I see that the mouse movement is mapped to some kind of perpendicular axes, but they're definitely not moving as you'd expect with respect to the camera. Could someone please explain what I'm doing wrong and point me in the right direction with this camera stuff?

  • Project Euler 12: (Iron)Python

    - by Ben Griswold
    In my attempt to learn (Iron)Python out in the open, here’s my solution for Project Euler Problem 12.  As always, any feedback is welcome. # Euler 12 # http://projecteuler.net/index.php?section=problems&id=12 # The sequence of triangle numbers is generated by adding # the natural numbers. So the 7th triangle number would be # 1 + 2 + 3 + 4 + 5 + 6 + 7 = 28. The first ten terms # would be: # 1, 3, 6, 10, 15, 21, 28, 36, 45, 55, ... # Let us list the factors of the first seven triangle # numbers: # 1: 1 # 3: 1,3 # 6: 1,2,3,6 # 10: 1,2,5,10 # 15: 1,3,5,15 # 21: 1,3,7,21 # 28: 1,2,4,7,14,28 # We can see that 28 is the first triangle number to have # over five divisors. What is the value of the first # triangle number to have over five hundred divisors? import time start = time.time() from math import sqrt def divisor_count(x): count = 2 # itself and 1 for i in xrange(2, int(sqrt(x)) + 1): if ((x % i) == 0): if (i != sqrt(x)): count += 2 else: count += 1 return count def triangle_generator(): i = 1 while True: yield int(0.5 * i * (i + 1)) i += 1 triangles = triangle_generator() answer = 0 while True: num = triangles.next() if (divisor_count(num) >= 501): answer = num break; print answer print "Elapsed Time:", (time.time() - start) * 1000, "millisecs" a=raw_input('Press return to continue')
