  • 2D game collision response: SAT & minimum displacement along a given axis?

    - by Archagon
    I'm trying to implement a collision system in a 2D game I'm making. The separating axis theorem (as described by metanet's collision tutorial) seems like an efficient and robust way of handling collision detection, but I don't quite like the collision response method they use. By blindly displacing along the axis of least overlap, the algorithm simply ignores the previous position of the moving object, which means that it doesn't collide with the stationary object so much as it enters it and then bounces out. Here's an example of a situation where this would matter: According to the SAT method described above, the rectangle would simply pop out of the triangle perpendicular to its hypotenuse: However, realistically, the rectangle should stop at the lower right corner of the triangle, as that would be the point of first collision if it were moving continuously along its displacement vector: Now, this might not actually matter during gameplay, but I'd love to know if there's a way of efficiently and generally attaining accurate displacements in this manner. I've been racking my brains over it for the past few days, and I don't want to give up yet! (Cross-posted from StackOverflow, hope that's not against the rules!)

  • How To Get Browser To Open From Same Folder?

    - by Bad Learner
    I don't know how to make the title any more clear. Let me give an example - When I want to add an image to an article on my blog, I click "Browse" button in the image uploader, and then upload the image to the blog. The problem is, when I want to upload another image to my blog, I want the browser to look into the same directory; but it's always takes me to the "Recently Used" directory. Is there a way to change this? I hope I have made myself clear enough. EDIT: I only use Chrome, so I am referring to it.

  • On what basis would you split donation money among your open source team members without any strife?

    - by Vigneshwaran
    I am a developer of an open source project which is hosted in SourceForge. It started out as a little app then after some releases, it got more and more popular and it started consuming more time and responsibility from me. So I have enabled the donation option in SourceForge. I'm passionate to continue developing it for free but if (ever) any money comes in, how should I split it with my team? Should I split the amount equally among the number of team members? (50-50 as it is two-member team now) Number of classes, commits or any other valuable submissions by team members? Any other idea? What would you do in such situation? Please give your opinions. I hope this question will be useful for others.

  • How can a student programmer improve his teamwork skill?

    - by xiao
    I am a student right now. Recently, I am working in a project as a leader with three other students. Due to the lack of experience, our project is progressing slowly and our members are frustrated. They do not feel sense of accomplishment in the project. I am pressured and frustrated, too. But as a team leader, I think I need to push them. But I do not know how to do. Do I help them solve coding problem or just encouragement? But if I pay too much attention on it, it would slow down my own progress. It is a not technical question, but it is very common in software development. I hope veteran programmers would give me some suggestions. Thanks!

  • What is the role of C++ today?

    - by hades
    Currently I'm an IT student and I'm wondering what is still important in C++ today, what for is it used? I completed basic C++ course in my university but I can't imagine where can I use my knowledge and in which direction should I go learning C++. In other words what should I learn to become a successful C++ programmer? Currently I'm learning Java just because I don't see clearly in which area C++ could be useful today, but I clearly know which kind of work I'll be doing as a Java programmer. But I still hope that C++ isn't dead.

  • [Silverlight] How to choose the webcam resolution

    - by Benjamin Roux
    Hello, Today I’m gonna show you how to choose the webcam resolution when using Silverlight. By default most of them are in 640x480 which can be sometimes insufficient. VideoCaptureDevice source = devices.SelectedItem as VideoCaptureDevice; source.DesiredFormat = new VideoFormat(PixelFormatType.Unknown, 4096, 4096, 30); The magic thing with this line, is that the camera will choose the best resolution available (and not absolutely 4096x4096). You can also get all the supported formats using the SupportedFormats property. Hope this help.

  • Five development tools I can't live without

    - by bconlon
    When applying to join Geeks with Blogs I had to specify the development tools I use every day. That got me thinking, it's taken a long time to whittle my tools of choice down to the selection I use, so it might be worth sharing. Before I begin, I appreciate we all have our preferred development tools, but these are the ones that work for me. Microsoft Visual Studio Microsoft Visual Studio has been my development tool of choice for more years than I care to remember. I first used this when it was Visual C++ 1.5 (hats off to those who started on 1.0) and by 2.2 it had everything I needed from a C++ IDE. Versions 4 and 5 followed and if I had to guess I would expect more Windows applications are written in VC++ 6 and VB6 than any other language. Then came the not so great versions Visual Studio .Net 2002 (7.0) and 2003 (7.1). If I'm honest I was still using v6. 2005 was better and 2008 was simply brilliant. Everything worked, the compiler was super fast and I was happy again...then came 2010...oh dear. 2010 is a big step backwards for me. It's not encouraging for my upcoming WPF exploits that 2010 is fronted in WPF technology, with the forever growing Find/Replace dialog, the issues with C++ intellisense, and the buggy debugger. That said it is still my tool of choice but I hope they sort the issue in SP1. I've tried other IDEs like Visual Age and Eclipse, but for me Visual Studio is the best. A really great tool. Liquid XML Studio XML development is a tricky business. The W3C standards are often difficult to get to the bottom of so it's great to have a graphical tool to help. I first used Liquid Technologies 5 or 6 years back when I needed to process XML data in C++. Their excellent XML Data Binding tool has an easy to use Wizard UI (as compared to Castor or JAXB command line tools) and allows you to generate code from an XML Schema. So instead of having to deal with untyped nodes like with a DOM parser, instead you get an Object Model providing a custom API in C++, C#, VB etc. More recently they developed a graphical XML IDE with XML Editor, XSLT, XQuery debugger and other XML tools. So now I can develop an XML Schema graphically, click a button to generate a Sample XML document, and click another button to run the Wizard to generate code including a Sample Application that will then load my Sample XML document into the generated object model. This is a very cool toolset. Note: XML Data Binding is nothing to do with WPF Data Binding, but I hope to cover both in more detail another time. .Net Reflector Note: I've just noticed that starting form the end of February 2011 this will no longer be a free tool !! .Net Reflector turns .Net byte code back into C# source code. But how can it work this magic? Well the clue is in the name, it uses reflection to inspect a compiled .Net assembly. The assembly is compiled to byte code, it doesn't get compiled to native machine code until its needed using a just-in-time (JIT) compiler. The byte code still has all of the information needed to see classes, variables. methods and properties, so reflector gathers this information and puts it in a handy tree. I have used .Net Reflector for years in order to understand what the .Net Framework is doing as it sometimes has undocumented, quirky features. This really has been invaluable in certain instances and I cannot praise enough kudos on the original developer Lutz Roeder. Smart Assembly In order to stop nosy geeks looking at our code using a tool like .Net Reflector, we need to obfuscate (mess up) the byte code. Smart Assembly is a tool that does this. Again I have used this for a long time. It is very quick and easy to use. Another excellent tool. Coincidentally, .Net Reflector and Smart Assembly are now both owned by Red Gate. Again kudos goes to the original developer Jean-Sebastien Lange. TortoiseSVN SVN (Apache Subversion) is a Source Control System developed as an open source project. TortoiseSVN is a graphical UI wrapper over SVN that hooks into Windows Explorer to enable files to be Updated, Committed, Merged etc. from the right click menu. This is an essential tool for keeping my hard work safe! Many years ago I used Microsoft Source Safe and I disliked CVS type systems. But TortoiseSVN is simply the best source control tool I have ever used. --- So there you have it, my top 5 development tools that I use (nearly) every day and have helped to make my working life a little easier. I'm sure there are other great tools that I wish I used but have never heard of, but if you have not used any of the above, I would suggest you check them out as they are all very, very cool products. #

  • structure problem in Relational DBMS creation

    - by Kane
    For learning and understanding purpose, I currently want to try to make a small relational DBMS with simple features like (for now) only sequential reading/writing and CREATE TABLE, INSERT, SELECT, UPDATE and DELETE management. I am currently on the "think" part of the project and I am stuck on the way to store the read data in memory. First I was thinking of putting them properly on a structure, but the problem is that tables are all different, know the type of each column is not an issue, but I am not sure C provide a way to make fully dynamic structure. My second and current idea is to make a simple char array of the required length and just get the data by order with cast. But I am not sure if it is the good way to do that part, so I wanted to ask for your opinion and advices about that. Thanks in advance for your help. nb: I hope my question is enough clear and understandable, I still lack of pratice in english

  • Lost Traffic from Google Because of Meta-tag Adding

    - by Marian
    I have a site aroundnails.com. It has English version on subdomain en.aroundnails.com. Reading about language related meta-tags for Google, I have placed such a meta tag on the main page of main site: <link rel="alternate" hreflang="en" href="http://en.aroundnails.com/" /> By this way I have tried to say Google, that my site on en.aroundnails.com is the english version of main site, not a duplicate. After a fortnight I have lost a huge part of traffic from Google, more than a half. At the beginning of September I have moved this meta-tag, but traffic remained at the same level. Hope somebody can help me to solve this issue.

  • Is Haskell worth learning?

    - by Jason K
    I am looking at this question primarily from a career point of view, so I hope you answer it accordingly. I am fairly proficient with Python, can write C++ and I am a final year student of computer science engineering I am looking to learn Haskell because I have heard a lot about it. My question is: apart from learning it because of all the good I have heard about it, is it any good for my career? Is it used in the industry? I am curious to learn it but unless it helps me somehow in my career, I am not willing to make that change at this stage. Looking for some personal experiences here. Thanks!

  • GParted wont resize extended partitions

    - by Magnum Frost
    I have dual booted windows 7 and Ubuntu 12.04 LTS and have decided that I need more space on my Ubuntu partition. I used gparted on a Live CD to shrink my Windows 7 partition (/dev/sda3) but when i try to resize the extended partition (/dev/sda4), which houses my linux partition (/dev/sda6), the right click options are greyed out and there is a key next to the extended partition. I have resized the partitions within the extended partition before to provide room, but now I can go no further with that, and need to grow the extended partition. The free space lies to the left of the extended partition and there is a small amount of free space directly to the right as well. Also, within the extended partition is /dev/sda5 (ntfs) , which I have no idea what is on it, but most of the space (3.42GB) is used, /dev/sda6 (ext4, mount point: /), my partition containing Linux, and /dev/sda7 (linux-swap). I hope you guys can help me with this because I really don't want to screw something up while trying to resize the extended partition.

  • E-commerce for custom orders/customer image upload

    - by ansarob
    We have a client that needs an e-commerce site set up pretty quickly. As I have no experience with e-commerce, I am looking for some guidance. Basically, the two big features we need are: Ability for customer to add info about order (example: the name the customer wants to be put on the customizable product they ordered) Ability for customer to upload photo of product to be customized I hope this makes sense. Right now I am really looking into Shopify, but I can't tell if it does everything we need. I know you can add order notes when checking out, but not sure about image upload (maybe it can be added as an app through the API?).

  • How to see what's going on during shutdown

    - by Huygens
    Since a few weeks, Ubuntu freezes almost everytime when I shut it down. I know it because the shutdown animation stops and nothing is responsive: Ctrl+Alt+Del or AltGr+Syst+[r,e,i,s,u,b] don't make any difference. I have tried to look at various log files in /var/log but only INFO level message are logged. My hope to solve this problem would be to do a verbose shutdown, one where I could see what's going on, and so what's causing the problem, so I could start solving it. Therefore, as the title suggest it. Is there a way to see what's going on during shutdown? I could even go to the extreme of doing a step-by-step shutdown if this is the only way. Thanks for any tips.

  • How was collision detection handled in The Legend of Zelda: A Link to the Past?

    - by Restart
    I would like to know how the collision detection was done in The Legend of Zelda: A Link To The Past. The game is 16x16 tile based, so how did they do the tiles where only a quarter or half of the tile is occupied? Did they use a smaller grid for collision detection like 8x8 tiles, so four of them make one 16x16 tile of the texture grid? But then, they also have true half tiles which are diagonally cut and the corners of the tiles seem to be round or something. If Link walks into tiles corner he can keep on walking and automatically moves around it's corner. How is that done? I hope someone can help me out here.

  • Speaking at AMD Fusion conference

    - by Daniel Moth
    Next Wednesday at 2pm I will be presenting a session at the AMD Fusion developer summit in Bellevue, Washington State. For more on this conference please visit the official website. If you filter the catalog by 'Speaker Last Name' to "Moth", you'll find my talk. For your convenience, below is the title and abstract Blazing-fast code using GPUs and more, with Microsoft Visual C++ To get full performance out of mainstream hardware, high-performance code needs to harness, not only multi-core CPUs, but also GPUs (whether discrete cards or integrated in the processor) and other compute accelerators to achieve orders-of-magnitude speed-up for data parallel algorithms. How can you as a C++ developer fully utilize all that heterogeneous hardware from your Visual Studio environment? How can your code benefit from this tremendous performance boost without sacrificing your developer productivity or the portability of your solution? The answers will be presented in this session that introduces a new technology from Microsoft. Hope to see many of you there! Comments about this post welcome at the original blog.

  • What php programmer should know?

    - by emchinee
    I've dig the database here and didn't found any answer for my question. What is a standard for a php programmer to know? I mean, literally, what group of language functions, mechanisms, variables should person know to consider oneself a (good) php programmer? (I know 'being good' is beyond language syntax, still I'm considering syntax of plain php only) To give an example what I mean: functions to control http sessions, cookies functions to control connection with databases functions to control file handling functions to control xml etc.. I omit phrases like 'security' or 'patterns' or 'framework' intentionally as it applies to every programming language. Hope I made myself clear, any input appreciated :) Note: Michael J.V. is right claiming that databases are independent from language, so to put my question more precisely and emphasise differences: Practises or security, are some ideas to implement (there is no 'Pattern' object with 'Decorator()' method, is there?) while using databases means knowing a mysqli and a set of its methods.

  • Multiple problems using BOINC in Ubuntu 12.04

    - by Pablo Viollier
    I installed Berkeley's BOINC software in Windows and I loved it, however I'm having the following problems using it in Ubuntu 12.04: 1) The software doesn't appear in the systray, only in the Unity dock (left side) 2) I can minimize BOINC to the dock but when I open and close other program it maximizes again, wich is very annoying 3) The software can't be closed, it only minimizes to the Unity dock, and nothing happens using right click and close either 4) The software doesn't start at startup or as a startup application 5) It doesn't have a screensaver like in Windows I know it's a lot a problems, but I hope they can be fixed, because I love to use this software, and knowing it's open-software it would be a shame it didn't run on Ubuntu like it should.

  • use ubuntu notebook as second monitor for fedora desktop

    - by YumTum
    I was wondering if there is a possibility to use my netbook with ubuntu 12.04 as a second monitor for my fedora desktop, because its keyboard is broken but everything else is running just fine. I already read about x2x, but I hope there is a more direct way to do this (I mean not over the WLAN but e.g. via LAN etc... ). Would it be possible to directly use the monitor without even running the laptop? For example through an VGA adapter? Thanks for your replies!
