• I'm a CS student, and honestly I don't understand Knuth's books..

  - by Raymond Ho

  I stumbled this quote from Bill Gates: "You should definitely send me a resume if you can read the whole thing." He was talking about The Art of Programming books.. So I was pretty curious and want to read it all but honestly, I don't understand it at all.. I'm really not that highly intellectual being.. So this should be the reason why I can't understand it, but I am eager to learn.. I'm currently reading volume 1 about fundamental algo.. So is there any books out there that are friendly to novice/slow people like me? So I can build up myself and hopefully in the future I can read Knuth's book at ease..

• What are the fundamentals of game development?

  - by Matt

  Hi, I completely do not understand how a video game can be coded. I'm a beginner programmer and only have experience writing console applications that do math and what not. I do not understand how these logical processes can make images move on the screen (video games). Obviously if i jumped into a game development book or something like that I would understand but I am currently still getting a grasp of the fundamentals of programming in general. Could anyone give a simple explanation , coding wise, on the jump between making a computer do simple math to making a computer produce amazing graphical programs such as video games? Maybe there are some intro videos someone can point me to? I

• Understanding the Java Ecosystem

  - by syrion

  I have traditionally had the "luxury" of being a one-man development team. I've used Python extensively, have a reasonable command of Perl, PHP, and JavaScript. My problem is Java. I can write Java code. I'm not great at it--unlike Python, I rarely make use of anything unique to Java when I'm writing it. Furthermore, my experience is mostly in simple GUI/console programming. Unfortunately, I'm currently pursuing an IT degree where Java is the lingua franca. My database class is requiring that our projects be written in Java using servlets, and I just can't wrap my head around the ecosystem. Is there a good online overview of or tutorial on how the Java web ecosystem works? I have Thinking in Java, but it's mostly just the language itself (which I understand well enough to get by). I have looked at the Sun servlet tutorial, but it seems outdated.

• What sort of security method is this called (if it has a name)?

  - by loosebruce

  I have thought of a way of securing access to an application interacting with another application. Using this method Application 1 - "What is the sum of 1+1?" Application 2 - "3" Application 1 - "Access granted" Is this method used a lot, does it have a classification in the programming world? The advantages for me of using this is that I do not have to spend more effort implementing security keys/certificates. Any unauthorized machine trying to interpret it would give the correct result and identify itself as untrusted. What sort of weaknesses are there to doing this?

• Cheerp -- C++ for web: advance or regression?

  - by Henrique Barcelos

  Recently I've run into Cheerp, a C++ to Javascript compiler, which uses a modified version of clang to generate Javascript code from C++ sources. That makes me wonder: why in the seven kingdoms would someone do this in their right mind? I mean: why would you take a language that is not designed for web at all, that is far more convoluted and bureaucratic, write your code and then compile it into Javascript itself? Can anybody see any advantages in doing so? We surely can discard performance as a reason, because in the end it generates pure Javascript code. Is there anyone here that have real experience with this? P.S.: I'm not sure if this is an on topic question, but this is the most general forum about programming that I could find in the StackExchange network. Edit Although this seems like a subjective question, it is not. I am asking for reasons that this tool could be useful. I got interested at first, but started wondering why would someone use it.

• 2d shapes in XNA 4.0?

  - by Lautaro

  Having some experience of XNA but none of 3D programming. I have an idea i want to realize but i have not decided to do it in 3d or 2d. Im not sure which one will be best in XNA. I want to have a shape like a blob that can reshape depending on input. The morphing does not need to be very advanced. It could be a circle (2d) or globe (3d) that just has one point that moves slightly in a random direction. In ASP.NET i have made this through the 2d Draw classes where i can make lines, circles, squares etc and then modify the points that makes them up. But it seems to me that XNA does not have classes for making 2d shapes (can i get this confirmed?). If it had, then this would be the quickest solution for me.

• How can i get latency when using Game Center?

  - by Freddy

  I'm pretty new to network programming. Basically I'm using game center for making a relatively simple iPhone game using Game-center p2p. However i'm now working on a algorithm to improve the multiplayer performance. But, I need to know how long it took for a package to travel from one device to the another device (latency) for the algorithm to work good. As for now, I have solved the problem by sending a double with time interval since 1970 in the package and then I compare it with the time at the other device. However I have heard that the NSDate methods is connected to the internet, which also will cause latency so the time interval would not be perfectly correct. What is the ideal way to check for how long it take for a package to be sent?

• Would a professional, self taught programmer benefit from reading an algorithms book?

  - by user65483

  I'm a 100% self taught, professional programmer (I've worked at a few web startups and made a few independent games). I've read quite a few of the "essential" books (Clean Code, The Pragmatic Programmer, Code Complete, SICP, K&R). I'm considering reading Introduction to Algorithms. I've asked a few colleagues if reading it will improve my programming skills, and I got very mixed answers. A few said yes, a few said no, and a one said "only if you spend a lot of time implementing these algorithms" (I don't). So, I figured I'd ask Stack Exchange. Is it worth the time to read about algorithms if you're a professional programmer who seldom needs to use complex algorithms? For what it's worth, I have a strong mathematical background (have a 2 year degree in Mathematics; took Linear Algebra, Differential Equations, Calc I-III).

• Are there existing FOSS component-based frameworks?

  - by Tesserex

  The component based game programming paradigm is becoming much more popular. I was wondering, are there any projects out there that offer a reusable component framework? In any language, I guess I don't care about that. It's not for my own project, I'm just curious. Specifically I mean are there projects that include a base Entity class, a base Component class, and maybe some standard components? It would then be much easier starting a game if you didn't want to reinvent the wheel, or maybe you want a GraphicsComponent that does sprites with Direct3D, but you figure it's already been done a dozen times. A quick Googling turns up Rusher. Has anyone heard of this / does anyone use it? If there are no popular ones, then why not? Is it too difficult to make something like this reusable, and they need heavy customization? In my own implementation I found a lot of boilerplate that could be shoved into a framework.

• Easiest turn-base games you can think of?

  - by Edgar Miranda

  I'm planning to get into the process of programming multiplayer turn-base games. I would like to start off by making some of the simplest (yet fun) multiplayer turn-base games out there. What are some that you can provide? For example... Tic-Tac-Toe Rock-Paper-Scissors Checkers Some not so easy games... 4 in a row chess poker In terms of "ease" of implementation I'm mainly looking at logic. For example, Rock-Paper-Scissors has very simple logic, while chess has logic that is more complicated. So far I have the following: Hexagon Heroes of Might and Magic Nine Men's Morris Connect 4 21 (card game) Pen the Pig (The Dot game) Memory Match

• Starting my first project and have no idea about it. Guide please.

  - by Chankey Pathak

  I am a Computer Science student (6th semester). I want to make a project and I have a team of 4 people (My friends). So we are 5 people and we have decided to make a "Web based file explorer". The project will be similar to THIS one. How should we start with this project? We guys don't know much about programming. I know Java a little and I am a RHCE so can handle the server and all such administrative stuffs. Since this is our first project so we guys have no idea how we'll make it? I know Java and other guys in the group knows C#, ASP.NET, PHP, SQL and Joomla. Please guide and give your suggestions. Thank you. PS : Perhaps my question is not complete, if you want more information then leave a comment I will edit the question.

• Can't install lua on 12.04 on Chrome book

  - by Anthony

  I am currently trying to install lua on my Ubuntu 12.04 on Chrome book and I keep getting this error: I'm doing good learning different programming languages (self taught) and well I wanted to start learning Lua. That error is keeping me from doing that unfortunately. I've tried doing it with and without of root access and still no success. Does anyone know what might be causing the problem or of a different way of installing Lua? Thanks a ton! Don't mind the top of the image just me taking out my frustration.

• What are some recommended video lectures for a non-CS student to prepare for the GRE CS subject test?

  - by aristos

  Well the title kinda explains all there is to explain. I'm a non-cs student and was preparing to apply PhD programs in applied mathematics. But for my senior thesis I've been reading lots of machine learning and pattern recognition literature and enjoying it a lot. I've taken lots of courses with statistics and stochastics content, which I think, would help me if I get accepted to a program with ML focus, but there are only two CS courses -introduction to programming- in my transcript and therefore I decided to take the CS subject test to increase my chances. Which courses do you think would be most essential to have a good result from CS subject test? I'm thinking of watching video lectures of them, so do you have any recommendations?

• Future-proofing myself when learning to program.

  - by Chris Bridgett

  I want to learn to program in a 'future-proof' manner, if you like. Whilst Windows dominates the desktop OS marketplace (for now), obviously there is a lot of value in learning its languages/frameworks/API's and so on - this might be subject to change as new devices emerge or Windows shoots itself in the foot (over-friendly previews of Windows 8 don't look too appealing...). Would I be right in thinking that having a solid knowledge of C/C++ for back-end logic/low level programming and the like, combined with an extremely portable language like Java for GUI's and so on, would be a good basis for software development that will prove useful on the most amount of systems? - I'm talking desktop PC's, tablets, phones.

• College for Game Development [closed]

  - by Cole Adams

  I am currently a Freshman Computer Science Major at Samford University, but I am realizing that the actual field I want to get into is Game Development. I go to all of these classes that are supposed to make you well rounded that have nothing to do with what I want to do and frankly, after 18 years of schooling, I am sick of having to be in classes like that. I want to go to a Game Design/Development school where that is the priority and I am not overburdened with useless classes. At this point I am so tired of the Samford classes already that I am heavily considering taking next semester off and just getting a job and focusing on learning programming on my own or something like that. My question is what would be some good schools to apply to for enrollment in 2013 and what does it take to get into these schools? Thanks in advanced.

• Rotate a vector by given degrees (errors when value over 90)

  - by Ivan

  I created a function to rotate a vector by a given number of degrees. It seems to work fine when given values in the range -90 to +90. Beyond this, the amount of rotation decreases, i.e., I think objects are rotating the same amount for 80 and 100 degrees. I think this diagram might be a clue to my problem, but I don't quite understand what it's showing. Must I use a different trig function depending on the radians value? The programming examples I've been able to find look similar to mine (not varying the trig functions). Vector2D.prototype.rotate = function(angleDegrees) { var radians = angleDegrees * (Math.PI / 180); var ca = Math.cos(radians); var sa = Math.sin(radians); var rx = this.x*ca - this.y*sa; var ry = this.x*sa + this.y*ca; this.x = rx; this.y = ry; };

• What's a good tool for Scrum Project Management in game development? [closed]

  - by BleakCabalist

  I'm looking for an efficient, easy-to-learn tool for Scrum project management not for proffesional use but to use it in my thesis concerning the use of Scrum in game development. Basically I want to visualize a production process of a hypothetical game. Some fragments of the production process should be really detailed to make my point, so basically user stories, tasks, burndown charts etc. are a must. I'm using Scrum, Kanban and some Lean practices for eliminating waste. I also want to use Extreme Programming practices in this production process including TDD and Continuous Integration. I have zero experience in proffesional project management so I need something that's fairly simple to use for a newb like me. Anyone can recommend a tool like that? For now I was thinking about TargetProcess and ScrumWorks. Thanks.

• .NET Libraries Cost More Than Windows?

  - by Kevin Mark

  When looking into libraries to make my programming life a little bit easier I've (almost) always been disappointed by the prices offered. For instance, Actipro's WPF Studio is $650. I suppose that's worth it if you plan to make money from the use of those controls. But take a look at, say, Windows. Windows 7 Ultimate is just about $220. I consider Windows to be a far more complex and "worth-it" product/purchase than a library that runs on it. Why the significant difference in pricing? Do libraries really need to be so expensive, or do they need to charge more in order to make a decent some of money?

• Are keyboard layouts inherently flawed for programmers?

  - by Craige

  Lately I've been noticing my keyboard usage more and more and how it affects my productivity. It brought to mind a question/problem that I believe has not been truly solved in the programming community (partially based on individual preferences). Are all/most keyboard layouts inherently flawed for programmers? What changes to your keyboard layout do you feel would increase your productivity most? Edit Remember when answering that there are a number of different factors that could make a keyboard layout flawed. For instance, if you type as fast as you believe you need to, but hitting common keys is uncomfortable, said keyboard layout could be considered flawed.

• What's the most effective way to perform code reviews?

  - by Paddyslacker

  I've never found the ideal way to perform code reviews and yet often my customers require them. Each customer seems to do them in a different way and I've never felt satisfied in any of them. What has been the most effective way for you to perform code reviews? For example: Is one person regarded as the gatekeeper for quality and reviews the code, or do the team own the standard? Do you do review code as a team exercise using a projector? Is it done in person, via email or using a tool? Do you eschew reviews and use things like pair programming and collective code ownership to ensure code quality?

• Microsoft and Joyent Announce Node.js Windows Port

  With the Node.js command line tool, developers can type ?node my_app.js.' to run JavaScript programs. It gives developers a JavaScript application programming interface (API) supplies access for the network and file system as well. One instance where Node.js often comes in handy is in the creation of scalable networked programs that emphasize high concurrency and low response times. Developers who wish to use Node.js use on Windows at this time must do so running a virtual machine with Linux.

• What do you call "X <= $foo <= Y" comparison?

  - by Jakob

  While writing a Perl statement like if ( $foo >= X && $foo <= Y ) yet again, I wondered why many programming languages do not support the more comfortable form if ( X <= $foo <= Y ) and what this is called. I came up with "3-legged comparison" but no results when searching for it. By the way there is also the "element-of-set" form if ( $foo in X..Y ) which I only consider more readable when provided via a short keyword. Is there a term for X <= $foo <= Y comparison? Which languages support it?

• Why should most logic be in the monitor objects and not in the thread objects when writing concurrent software in Java?

  - by refuser

  When I took the Realtime and Concurrent programming course our lecturer told us that when writing concurrent programs in Java and using monitors, most of the logic should be in the monitor and as little as possible in the threads that access it. I never really understood why and I really would like to. Let me clarify. In this particular case we had several classes. Lift extends Thread Person extends Thread LiftView Monitor, all methods synchronized. This is nothing we came up with, our task was to implement a lift simulation with persons waiting on different floors, and theses were the class skeletons that were given. Then our lecturer said to implement most of the logic in the monitor (he was talking about class Monitor as THE monitor) and as little as possible in the threads. Why would he make a statement like that?
