• Contract Programming - Deposit % and Payment Methods? Any advice is appreciated

  - by Rick

  I'm pretty new to doing contract work and finally landed a decent paying project. The guy actually offered to put down a deposit and I'm just wondering what percentage I should consider asking for. I was thinking around 25% since its not a terribly large project (only about 20 hours). Also, I can't use PayPal (have had a terrible experience with them freezing funds for no good reason) so I'm wondering if anyone can suggest other methods for the client to send the deposit / payment. I want to make it as easy as possible for them.. thanks for any advice

• Lag compensation of projectile shooting game

  - by Denis Ermolin

  I'm thinking about an algorithm for firing projectiles with lag compensation. Now I did find only one descent solution: Player hits fire button. Client sends input "fire". Client waits for server response. Server generates bullet then sends response to client. Client recieves response and finally fires projectile. Is this solution only "trueway"? I find it the only one that can be fair to all of the clients. Valve in this case, doesn't compensate lag from rocket shots. I am feeling that I will not compensate it, too. I think that with today's bandwidth I can close my eyes on this problem, because I don't see any solutions with fair logic. What do you think?

• Doubts regarding the behaviour of 'autoremove' command and '--auto-remove' flag

  - by Jasper Loy

  After reading several man pages and forums, I thought that running 'apt-get autoremove' without any following argument removes all unused dependencies left on the system, while running 'apt-get autoremove xxx' removes xxx together with its unused dependencies. However I found this to be not true. Running 'apt-get autoremove xxx' not only removes xxx together with its unused dependencies, it also removes all other unused dependencies. So I tried to run 'apt-get remove --auto-remove xxx', thinking that this would remove only xxx and its unused dependencies. To my surprise, this also removed xxx, its unused dependencies and all other unused dependencies. Is this the intended behaviour of the commands or a bug? Is there any quick way to remove xxx and its unused dependencies without removing other unused dependencies?

• How to export a C++ class library to C# using a dll?

  - by SICGames2013

  In my previous revision game engine I deported major functions for the game editor for C#. Now, I'm beginning to revise the game engine with a static library. There's a already dynamic library created in C++ to use DLLEXPORT for C#. Just now I want to test out the newer functions and created a DLL file from C++. Because the DLL contains classes I was wondering how would I be able to use DLL Export. Would I do this: [DLLEXPORT("GameEngine.dll", EntryPoint="SomeClass", Conventional=_stdcall)] static extern void functionFromClass(); I have a feeling it's probably DLLImport and not DLLExport. I was wondering how would I go about this? Another way I was thinking was because I already have the DLL in C++ prepared already to go the C# Class Library. I could just keep the new engine as a lib, and link the lib with the old DLL C++ file. Wouldn't the EntryPoint be able to point to the class the function is in?

• How to keep a team well-trained?

  - by PierrOz

  Hi dear fellows, I'm currently mentoring a small team of 4 junior dev in small software company. They are very smart and often achieve their tasks with a high-quality job but I'm sure they still can do better - actually I have exactly the same feeling for myself :) -. Besides some of them are more "junior" than other. So I would like to find of a funny way to improve their CS skills (design, coding, testing, algorithmic...) in addition to the experience they acquire in their daily work. For instance, I was thinking of setting up weekly sessions, not longer than 2 hours, where we could get together to work on challenging CS exercises. A bit like a coding dojo. I'm sure the team would enjoy that but is it really a good idea? Would it be efficient in a professional context? They already spend all their week to code so how should I organize that in order for them to get some benefits? Any feedback welcome !

• Programming Challenges for a beginner

  - by JMK

  I'm in an unusual situation. A colleague of mine wants to "learn programming" and, being a developer I have been tasked with teaching him "programming". Personally, I am self taught, and have never taught any sort of skill to anybody else before so I am not quite sure where to start. Also, I still have a heck of a lot to learn myself (although don't we all)! I write in C# but is C# a good language for a beginner? I was thinking that Visual Basic .Net would be a better starting point, so was considering getting him setup with Visual Studio Express 2010, teaching him a few basics (variables, functions, classes etc) then finding some programming challenges and asking him to work through these. Does anybody have a good source of these sorts of challenges? Also is this a good strategy? Finally, what are your experiences of teaching programming to somebody else and what advice would you give?

• What payment processors fullfill this requirements and what are their pluses and minuses? [on hold]

  - by Sharen Eayrs

  Accept credit card Allow me to automatically credit a customers' account. We're not selling e-book. We're selling a credit to our account. So it's important that customers do not get credited twice. Easy to program and integrate with our sites. Have affiliate programs. Transfer money to bank accounts quickly Accept merchants from many countries No monthly fee is a plus. I am thinking of using 2co.com avangate.com clickbank.com Some people reccomend https://stripe.com/us/features (is it easy to implement) http://www.paymentwall.com/ There are so many payment processor I am very confused. Can anyone tell me pluses and minuses of those ones. or perhaps others. What would be the plus and minuses of those 3 that you know off

• What has the most efficient intersection test against an AABB tree - OBB, Cylinder or Capsule?

  - by identitycrisisuk

  I'm currently trying to find collisions in 3D between a tighter volume than an AABB and a tree of AABB volumes. I just need to know whether they are intersecting, no closest distance or collision response. An OBB, Cylinder or Capsule would all roughly fit these purposes but Cylinder and Capsule were the first thing I thought of, which I have found little information about detecting intersections online. Am I right in thinking that they would always be more complex to perform Separating Axis Tests on even though they might seem like simpler shapes? I figure by the time I get my head around SAT for curved shapes I could have done the thing with OBBs but I wanted to find out for sure.

• Is client side JavaScript capable of replicating the Node.JS module loading system?

  - by jt0dd

  I like the Node.JS style of JavaScript, where I can write all of my functionalities into smaller files and then require those neatly from within my code. I'm even thinking about trying to write a framework to mimic that behavior in client-side JS. My goal would be to implement the module loading system as accurately as possible - See Module docs. For require(), I can use things detailed in answers to this question, most notably JQuery's $.getScript(). It seems to me that other aspects of the module loading system should be possible as well. So I'm asking more experienced programmers here first, before I waist my time: Is there something that I'm missing that's going to cause such an attempt to fail miserably, or can this be successfully done?

• SuperSocket

  - by csharp-source.net

  SuperSocket is a light weight extensible socket application framework. You can use it to build a command based server side socket application (like FTP server, SMTP/POP3/IMAP4 server, SIP server, etc) easily without thinking about how to use socket, how to maintain the socket connections and how socket works(synchronize/asynchronize). It is a pure C# project which is designed to be extended, so it is easy to be integrated to your existing system. As long as your systems (like forum/CRM/MIS/HRM/ERP) are developed in .NET language, you must be able to use SuperSocket to build your socket application as a part of your current system perfectly.

• Snooker Android Application [closed]

  - by Rzarect

  I am working currently on my final year project / dissertation for the university and I have a "crazy" idea for it. I was thinking of designing an android app for Snooker players, different bars or tournaments, an app that will use the mobile camera to detect every movement and change on the table and in the same time will keep the score for the players without any human input. I want to know if it is an impossible thing. If it is plausible I really need some ideas, advices from where to start. I got to say that I have some experience in Android development and I already started to read a lot of articles, projects about the shape detection, color detection and edge detection.

• Any learning/studying material for C/C++ that use game programming as learning context out there?

  - by mac

  As most of game programming is done - I read on this very site - in C/C++ I was wondering if there is any learning/studying material for C/C++ that would target specifically game programming. I am not looking for material about "developing games" or "software architecture for games", but rather for material that uses "game programming" as the CONTEXT for introducing and illustrating C/C++ features, idioms, programming techniques, etc... With a simile: think to the GOF book on design patterns. There, they used "developing a text-editor" as a context for introducing design patterns, but the book is most definitively not a book about "developing text-editors". Thanks in advance for your time and advice! PS: My background: I am a programmer with a solid experience in OO scripting languages and only some experience in C and Assembler (on AVR microcontrollers), so I am thinking to mid-to-advanced level material, rather than tutorials for beginners, although it might be interesting to take a look to the latter ones if nothing else is available.

• Programming *into* a language vs. writing C code in Ruby

  - by bastibe

  Code Complete states that you should aways code into a language as opposed to code in it. By that, they mean Don't limit your programming thinking only to the concepts that are supported automatically by your language. The best programmers think of what they want to do, and then they assess how to accomplish their objectives with the programming tools at their disposal. (chapter 34.4) Doesn't this lead to using one style of programming in every language out there, regardless of the particular strengths and weaknesses of the language at hand? Or, to put the question in a more answerable format: Would you propose that one should try to encode one's problem as neatly as possible with the particulars of one's language, or should you rather search the most elegant solution overall, even if that means that you need to implement possibly awkward constructs that do not exist natively in one's language?

• Good practices in screen states management?

  - by DevilWithin

  I wonder what are the best ways to organize different screens in a game? I am thinking of it like this: Inheriting a base State class, and overriding update and render methods, to handle the current screen. Then, under certain events a StateManager is able to activate another Screen State, and the game screen changes as only the current State is rendered. On the activation of a new screen, effects like fading could be added, and also the same goes for its deactivation. This way a flow of screen could be made. By saying when A ends, B starts, allowing for complex animations etc. Toughts?

• What are the system requirements for each flavor of Ubuntu Desktop?

  - by Braiam

  I'm thinking about installing Ubuntu Desktop, but I don't know what flavor is the better for my system. What are the minimum and recommended hardware requirements? What kind of CPU? How much memory? Should I have Hardware Acceleration? What flavor should I use? This is an attempt of a canonical answer. My answers have the "official minimal requirements", the recommended are a mix of official sources and opinion based (along with the answer it's told the source). You can comment or edit if you feel that the information is obsolete or incomplete. Is a good rule of thumb that any system capable to run Windows Vista, 7, 8 x86 OS X will almost always be a lot faster with any Ubuntu flavor even if they are lower-spec than described below.

• Modules already committed, client doesn't pay, what should I do?

  - by John

  So the story is simple, early stage EU portal hired me to do some extra modules. I got all the source code for local testing, did my job, committed new code. Now I am out of this project but client still haven't paid me yet and he is not even thinking about that. It has been couple of months and no contract was signed so I can't take any legal actions. What should I do with all the source code? Sell it? Run exact copy of that portal? Make all portal publicly available?

• Doing practice jobsearch/technical interviews?

  - by Beekguk

  I graduated college last year & I've never gone through the interview process - my current programming position evolved out of projects I did in school, but in a few months I'm making a clean break and moving across the country so I'm going to have to face a "grown-up" jobsearch. I'm kind of scared of technical interviews - I think I'm pretty good at my job and my hobby programming projects ... but what if it turns out I'm part of that group that thinks they're qualified, but really just cause despair at the state of education in the hearts of interviewers? So, I'm thinking of doing a "practice" job hunt in my current city to get an idea of what it's like and what kind of experience/expertise employers are really looking for. Is this a dick move ethically (applying to/interviewing for jobs I can't take)? If so, is there another good way to prepare for technical interviews, especially those little trick puzzle-type questions?

• Finding inspiration / help for making up (weapon) names

  - by Rookie

  I'm really bad with words, especially with English words. Currently I'm struggling to make a good weapon names for my game, it needs to display the weapon functionality (weak/strong/fast/ballistic etc) correctly as well. For example the best weapon in a (futuristic) game cannot be called just with the name "Laser", it's just too boring, right? Are there any tools, websites or anything that helps me finding good names for weapons? (or anything else similar). I was thinking to use scientific names, but noticed that they are really hard to write, and they get very long, and I also lack information about science, I only know I could use the atomic sub-particles names in the weapons for example. How do I get started with becoming good with making up names? (this could apply in generally to any naming problems).

• New Bing Maps

  - by MikeParks

  Normally I don't stray too far from Programming and TFS on my blog posts but I'm just really impressed with how much Silverlight has improved Bing maps. I use to be big on MapQuest, then hopped over to Google, but now the new Bing Maps have everything I need. The two coolest features are right on the main page. All you have to do is go to http://www.bing.com/maps/explore/, enter your city and hit enter in the search box, then look in the lower left corner under the EXPLORE section. Check out the "What's nearby" and "Restaurants" links. The best part is, if you're interested in doing any Silverlight programming, they have a Bing Maps Silverlight Control Interactive SDK. I was thinking about coding something....but they've pretty much got it down :) Pretty impressive stuff.

• Google Dart vs CoffeeScript? Which one should one learn?

  - by garbage collection

  I was thinking about learning CoffeeScript some time in the future. In the mean time, Google came out with Dart that seems to do what CoffeeScript does. Google says: Dart code can be executed in two different ways: either on a native virtual machine or on top of a JavaScript engine by using a compiler that translates Dart code to JavaScript. This means you can write a web application in Dart and have it compiled and run on any modern browser. Does anyone know advantages and disadvantages of learning Dart or CoffeeScript?

• Objects disappear when zoomed out in Unity

  - by Starkers

  Ignore the palm trees here. I have some oak-like trees when I'm zoomed in: They disappear when I zoom out: Is this normal? Is this something to do with draw distance? How can I change this so my trees don't disappear? The reason I ask is because my installation had a weird terrain glitch. If this isn't normal I'm going to reinstall right away because I'm always thinking 'is that a feature? Or a glitch'?

• Drawing out a document with strategies for coping with "disasters"

  - by James Poulson

  Does anyone happen to know of some guidelines for writing up a document for coping with possible disaster scenarios ? By disaster I mean anything that could lead to loss of work, time or eventually a client. I seem to remember reading an article along these lines but, unfortunately, I can't find it anymore. So I'd appreciate some feedback in this direction. I think such an approach would be useful in the company I'm in right now as we've had the occasional scare which might have been avoided with some preventative thinking.

• Listing technologies on a resume for a software position when your background is game programming?

  - by Ford

  So I'm thinking about applying for a entry level position in the software industry but my limited experience working and all my notable experience in college is with game technologies. Sure, the languages transfer over well but most of the technologies I have experience with are all related to graphics programming, engines of various types, and such, and do not transfer over at all. I feel like it would be inappropriate to just take my game programming resume and basically replace the word game with software for the reasons mentioned but on the other hand if I take them out I will only have languages and some technologies that I have some small passing experience with- which will obviously not reflect well on me. Should I leave them out or put them in, and if so how can I spin them to be appropriate?

• Are there any alternative JS ports of Box2D?

  - by Petteri Hietavirta

  I have been thinking about creating a top down 2D car game for HTML5. For my first game I wrote the physics and collisions my self but for this one I would like to use some ready made library. I found out Box2D and its JS port. http://box2d-js.sourceforge.net It seems to be quite old port, made in 2008. Is it lacking many features of current Box2D or does it have major issues with it? And are there any alternatives for it?
