  • XNA - positioning after rotation

    - by DijkeMark
    I have a turret with a 2 gunbarrels. The turret rotates towards my mouse. So far no problem. When it creates a few bullets and positions them at the end of the gun barrels. Here is the problem. It only works the moment the gun is point upwards. The moment it rotates the end of the gun barrels have moved ofcourse, thus the bullets don't spawn at the end of the gun battels, but at the place the where the gun barrels are when the turret is pointing upwards. How can I check where the end of the gun barrels are the moment it rotates? Thanks in Advance, Mark Dijkema PS. If you need code please let me know, I didn't post any yet, because I didn't what code you would need.

  • How to tackle archived who-is personal data with opt-out?

    - by defaye
    As far as I understand it, it is possible to opt-out (in the UK at least) of having your address details displayed on who-is information of a domain for non-trading individuals. What I want to know is, after opt-out, how do individuals combat archived data? Is there any enforcement of this? How many who-is websites are there which archive data and what rights do we have to force them to remove that data without paying absurd fees? In the case of capitulating to these scoundrels, what point is it in paying for the removal of archived data if that data can presumably resurface on another who-is repository? In other words, what strategy is one supposed to take, besides being wiser after the fact?

  • How to determine collision direction between two rectangles?

    - by Jon
    I am trying to figure out how to determine the direction a collision occurs between two rectangles. One rectangle does not move. The other rectangle has a velocity in any direction. When a collision occurs, I want to be able to set the position of the moving rectangle to the point of impact. I seem to be stuck in determining from what direction the impact occurs. If I am moving strictly vertically or horizontally I manage great detection. But when moving in both directions at the same time, strange things happen. What is the best way to determine what direction a collision occurs between two rectangles?

  • What's the reason exceptions are heavily used in managed (C# and Java) languages but not in C++? [on hold]

    - by ZijingWu
    AFAIK, a lot of C++ projects don't allow exceptions and deny them in coding guidelines. I have a lot of reasons, for example, exception is hard to handle correctly if your binary needs to be compiled by separate and different compilers. But it doesn't fully convince me, there is a lot of projects which are just using one compiler. Compared to C++, exceptions are heavily used in C# and Java and the reason can only be that exception are not bringing enough benefit. One point is debugbility in practice. Exception can not get the call stack in C++ code, but in C# and Java you can get the call stack from exception, it is significant and makes debugging easier. No-callstack is not the fault of the exception, it is the language difference, but it impacts the exception usage. So what's the reason that exceptions are frowned upon in c++ programs?

  • Does Ubuntu 12.04 supports for B75 boards?

    - by rail02000
    I want to build a new computer with Intel G840 CPU and Gigabyte B75M-D3H motherboard and install Ubuntu (or Kubuntu) 12.04 64bit on it. However, I'm worried about whether the chip is too new and whether that Linux Kernel now has support for it. According to the article [Phoronix] Intel Core i7 3770K Ivy Bridge Linux Performance Review ,the Linux kernel is ready to work on the chip. Existing Intel Sandy Bridge motherboards/chipsets are compatible with Ivy Bridge processors, but earlier this month Intel launched the new Panther Point chipsets that are already compatible with Linux too: the B75, H77, Z75, Z77, HM75, HM76, UM77, and HM77. But I didn't find further information or cases about running Ubuntu on the chip. So,is it OK to run Ubuntu on the board? Do I need to upgrade the kernel to a newer version (3.4 or 3.5 etc.) to get the system more smoothly? Or should I choose boards with H61 chip? Thank for your response!

  • rotate opengl mesh relative to camera

    - by shuall
    I have a cube in opengl. It's position is determined by multiplying it's specific model matrix, the view matrix, and the projection matrix and then passing that to the shader as per this tutorial (http://www.opengl-tutorial.org/beginners-tutorials/tutorial-3-matrices/). I want to rotate it relative to the camera. The only way I can think of getting the correct axis is by multiplying the inverse of the model matrix (because that's where all the previous rotations and tranforms are stored) times the view matrix times the axis of rotation (x or y). I feel like there's got to be a better way to do this like use something other than model, view and projection matrices, or maybe I'm doing something wrong. That's what all the tutorials I've seen use. PS I'm also trying to keep with opengl 4 core stuff. edit: If quaternions would fix my problems, could someone point me to a good tutorial/example for switching from 4x4 matrices to quaternions. I'm a little daunted by the task.

  • What does it mean to "have experience with the Unix/Linux command line"? [closed]

    - by Aerovistae
    I'm a new comp sci grad applying to jobs, and this requirement confuses me, especially since the job description (Python back-end developer) says it's the single most important thing ("Everything else we can teach you!") I mean, I know how to use the command line... I know your standard run-of-the-mill stuff like navigating around and manipulating files and permissions and using pipes and running applications, but what are they looking for when they say something like that? I'm aware there's no end to what you can do with the command line, but I was under the impression that after a certain point it's the sort of thing that only benefits server/system administrators.

  • Package version updates policy

    - by Sandman4
    Not sure if here it's the right place to ask, if not - please point me to the right direction. Let's say there's a package, for the sake of real-world example - bind9. In Precise and in Quantal it's version 9.8.1. The original developer (ISC) currently provide versions 9.8.4 which is a bugfix release in the 9.8 line, and 9.9.2 which is a "new features" branch. It looks like when a security issue is encountered, the specific bugfix is backported into 9.8.1. Now the question: Why maintainers don't just update to the latest bugfix release ? Why to backport only certain patches ? Is it intentionally or just there's no maintaner who would take the effort to update to the latest bugfix release ?

  • Why did 13.10 break my custom keyboard layout?

    - by con-f-use
    I was using a custom keyboard layout. Basically I modified the us-mac layout to fit my ideal of a math-heavy version of the regular us layout that also throws German umlauts into mix. It went well and worked marvelously for 6 consecutive versions of Ubuntu. Today's version Upgrade (from 13.04 to 13.10) broke that streak. I now have the usual crappy Macintosh-Layout. Now xkb just ignores my layout and all of the other changes I make in /usr/share/X11/xkb/symbols/us (tried to switch '0' and '9' everywhere and rebooted - no effect). Why is that? I suspect I have to do an extra step now for the changes to take effect or something like that. Anyone care to point me in the right direction?

  • Does tweeting 9 to 5 hurt job applicants?

    - by evadeflow
    If you were looking into a job applicant's background and discovered that he or she has 1200 followers on Twitter and averages 50 tweets per day (more than half of which are during business hours), would it affect your hiring decision? How and why? Personally, I'd be a little worried about the candidate's ability to focus on the job at hand if they're constantly checking in with their 'tweeps' thoughout the day. In non-tech jobs, a lot of companies simply block Twitter as an irrelevant distraction. But it can be a useful resource---to programmers in particular. I just wonder how much is too much. At what point does it become a red flag?

  • Windows 7 and 11.10 side by side from scratch what am I doing wrong?

    - by Bill.Caffery
    I have tried everything I can think of at this point and I'm at a total loss. I have a 2TB drive I want to install Windows 7 and 11.10 (both are 64 bit) side by side, but once I install Windows it must need gpt to work or something because no matter how many times I've removed it, it always returns. If I use gdisk and set the disk as mbr, Windows won't load. Now this last time I ran gdisk and tried to boot into Windows before I installed Ubuntu all the way and ended up at a grub rescue prompt. Any help please? Also let me say I have been searching and reading for days and have tried everything I can find to make this work so this isn't a one time event, it's continual.

  • Website creation preparation [closed]

    - by Loki
    I am in the pre-coding phase of creating a website. I know that it will be account based (users have to register/login to use the features). I also know that the server will have to do certain operations that are timer based, that is to say that user will have events that will trigger at a point chosen by the user and do something. I am searching for a good choice in server-side technology, and was wondering what my options are and what the best choice is. I would prefer open technology and something that doesn't use interpreted languages (Java, .net). My first thought is PHP + PGSQL for serverside and HTML+CSS+JS for clients, but I am still looking at my options.

  • Are there any surveys on to what degree developers like or hate scrum ?

    - by dparnas
    Background: During a conference an analyst pointed out in a tweet that developers hate scrum. Myself and another person responded that this was not the case, and started discussing different scenarios on why developers would dislike scrum. One of the scenarios where that lazy developers are not able to hide in a scrum project. They are constantly challenged by the team to contribute. This discussion resulted in a blog post and video http://elsewhat.com/2010/05/20/lazy-developers-hate-agile-and%C2%A0scrum/ I've gotten three comments which I've tried to answer in a neutral way, but they comments do point out that there are some people who loathe scrum (and I am always 100% certain they are not lazy developers). Question Have there ever been a survey among developers on to what degree developers like or hate scrum ?

  • Deep Cloning C++ class that inherits CCNode in Cocos2dx

    - by A Devanney
    I stuck with something in Cocos2dx ... I'm trying to deep clone one of my classes that inherits CCNode. Basically i have.... GameItem* pTemp = new GameItem(*_actualItem); // loops through all the blocks in gameitem and updates their position pTemp->moveDown(); // if in boundary or collision etc... if (_gameBoard->isValidMove(pTemp)) { _actualItem = pTemp; // display the position CCLog("pos (1) --- (X : %d,Y : %d)", _actualItem->getGridX(),_actualItem->getGridY()); } Then doesn't work, because the gameitem inherits CCNode and has the collection of another class that also inherits CCNode. its just creating a shallow copy and when you look at children of the gameitem node in the copy, just point to the original? class GameItem : public CCNode { // maps to the actual grid position of the shape CCPoint* _rawPosition; // tracks the current grid position int _gridX, _gridY; // tracks the change if the item has moved CCPoint _offset; public: //constructors GameItem& operator=(const GameItem& item); GameItem(Shape shape); ... } then in the implementation.... GameItem& GameItem::operator=(const GameItem& item) { _gridX = item.getGridX(); _gridY = item.getGridY(); _offset = item.getOffSet(); _rawPosition = item.getRawPosition(); // how do i copy the node? return *this; } // shape contains an array of position for the game character GameItem::GameItem(Shape shape) { _rawPosition = shape.getShapePositions(); //loop through all blocks in position for (int i = 0; i < 7; i++) { // get the position of the first block in the shape and add to the position of the first block int x = (int) (getRawPosition()[i].x + getGridX()); int y = (int) (getRawPosition()[i].y + getGridY()); //instantiate a block with the position and type Block* block = Block::blockWithFile(x,y,(i+1), shape); // add the block to the this node this->addChild(block); } } And for clarity here is the block class class Block : public CCNode{ private: // using composition over inheritance CCSprite* _sprite; // tracks the current grid position int _gridX, _gridY; // used to store actual image number int _blockNo; public: Block(void); Block(int gridX, int gridY, int blockNo); Block& operator=(const Block& block); // static constructor for the creation of a block static Block* blockWithFile(int gridX, int gridY,int blockNo, Shape shape); ... } The blocks implementation..... Block& Block::operator=(const Block& block) { _sprite = new CCSprite(*block._sprite); _gridX = block._gridX; _gridY = block._gridY; _blockNo = block._blockNo; //again how to clone CCNode? return *this; } Block* Block::blockWithFile(int gridX, int gridY,int blockNo, Shape shape) { Block* block = new Block(); if (block && block->initBlockWithFile(gridX, gridY,blockNo, shape)) { block->autorelease(); return block; } CC_SAFE_DELETE(block); return NULL; } bool Block::initBlockWithFile(int gridX, int gridY,int blockNo, Shape shape) { setGridX(gridX); setGridY(gridY); setBlockNo(blockNo); const char* characterImg = helperFunctions::Format(shape.getFileName(),blockNo); // add to the spritesheet CCTexture2D* gameArtTexture = CCTextureCache::sharedTextureCache()->addImage("Character.pvr.ccz"); CCSpriteBatchNode::createWithTexture(gameArtTexture); // block settings _sprite = CCSprite::createWithSpriteFrameName(characterImg); // set the position of the block and add it to the layer this->setPosition(CONVERTGRIDTOACTUALPOS_X_Y(gridX,gridY)); this->addChild(_sprite); return true; } Any ideas are welcome at this point!! thanks

  • One man software developer product success stories? [on hold]

    - by EugeneKr
    I've got a bad feeling that this question is not appropriate here.. Hopefully you can point me to the right place to ask such a thing (not google though, been there). I want to create my own product, but for some reason have no ideas, so decided to see what people have already done. I would like to start by myself too. I don't mind expanding, but at later stages when it is absolutely necessary. Anyway, to give you an example. There is a guy who created bingo card generation software, then somebody made a wedding planner software and they seem to be doing pretty fine. I would like to know more such cases to draw inspiration from. Do you know such people or maybe you are one of them? Also, if there are places on the net where they dwell, don't hesitate to tell me :) Thanks!

  • How to deal with readers requesting free advice / support on my blog? [closed]

    - by russau
    I have a handful of popular articles on my blog (nothing huge), and they attract the occasional developer who wants help implementing some code grabbed from my blog. Now I'm getting people who haven't made any attempt to learn the code, email me their code, and expect me to trace it through for them. I'm sure anyone with a half-popular blog gets similar requests. What's the best way to deal with this scenario? I want to put together a boilerplate response including these points: How far have you gone with this on your own? (is it any benefit for anyone if I say they are being imposing) I'm happy to help with any problems you find in my code Point them to other forms of help such as stackoverflow, diagnostic tools relevant to the topic.

  • How can one get involved in the Ubuntu Brainstorm team?

    - by Jay
    I've heard it thrown around on a lot of blogs that Ubuntu Brainstorm is the "graveyard of good ideas". I have a bit of a passion for average end-users suggesting the kinds of software they want and they way they think their applications and computers could work. I'm interested in joining the Ubuntu Brainstorm team, maybe to facilitate ideas not getting buried and making it not seem like a dead platform. Unfortunately I'm not very plugged into the "community" so I'm not sure how to go about it. I was hoping someone might be able to point me in the right direction. Thanks.

  • Which is the appropriate content-type meta tag value ?

    - by Argoron
    I have a question about the meta tag content-type. When starting to build my site (HTML+PHP+JS), I copied a lot of the meta tags over from elsewhere, and I have, amongst others, the following: <meta http-equiv="content-type" content="application/xhtml+xml; charset=iso-8859-1" /> Now, I've seen that tag is being used a lot with the value "text/html". I've been searching the web but could not find a comprehensive explanation regarding what the difference between both is. The "text/html" intuitively sounds more straightforward to me. Should I change my tag to that, or might the "application/xhtml+xml" be an equivalent solution ? Alternatively, can anyone point me to a resource where the different values for these tags are listed and explained in a clear manner? Thanks in advance

  • phishing attack. Where do I start the cleanup?

    I'm a newbie webmaster. I've got a domain and a site... and no clue about the web (I'm OK with files and programs... ) I got a message from google that my site is a possible phishing site, with a link the the suspect page: http://www.mydomain.com/~phishers/Paypal/us/Confirm.php needless to say, I didn't put that up. Can someone point me to a good tutorial on what to do now? I'd like to figure out what happened so I can defend against it the next time around. How do I identify what kind of attach this is? Also, what is the tilde doing in the URL path? I couldn't find any path like this on my hosting account, so I'm not entirely sure how to delete it.

  • Are people getting away with the "follow 1000s and then unfollow" Twitter trick? [closed]

    - by Baumr
    It seems that more and more people are trying to 'cheat' their way into more Twitter followers. The basic mechanism is: Follow thousands of people on Twitter with the hope that they'll follow you back. Once it reaches a point you're happy with, start gradually unfollowing them. That way, at the end of the day, it'll look like a lot of people follow you unconditionally. I've seen self-proclaimed social media and SEO experts do this. It's clear they want to look influential — and will use black hat social media tactics to do so. I can see how it can work, so is Twitter letting them get away with it? Should it?
