  • Fetching templates via API. Who provides this service?

    - by Guandalino
    I'm mainly a server side developer. I'm not a designer, even if I understand web layouts, grids, CSS, typography, valid markup, etc. and I'm able to do some graphic work too (almost). It just takes a lot of time and the result is not always beautiful. I know there are tons of website templates sites out there, and I'd like to use their designs as a starting point for my customers' works, giving them the possibility to choose the design they like more. I'd just prefer to show the templates catalog to customers from within my site, fetching templates info (screenshots, description, etc) from a remote server using an API. TemplateMonster.com provides, or provided, such API. But the service responds with "Unauthorized usage". Are there other sites offering this kind of retrieval service?

  • ContentManager in XNA cant find any XML

    - by user36385
    Im making a game in XNA 4 and this is the first time I'm using the Content loader to initialize a simple class with a XML file, but no matter how many guide I follow, or how simple or complicated is my XML File the ContentManager cant find the file; the Debug keep telling me: "A first chance exception of type 'Microsoft.Xna.Framework.Content.ContentLoadException' occurred in Microsoft.Xna.Framework.dll". I'm really confuse because I can load SpriteFonts and Texture2D without a problem ... I create the following XML (the most basic Xna XML): <?xml version="1.0" encoding="utf-8" ?> <XnaContent> <Asset Type="System.String">Hello</Asset> </XnaContent> and I try to load it in the LoadContent method in my main class like this: System.String hello = Content.Load<System.String>("NewXmlFile"); There is something I'm doing wrong? I really appreciate your help

  • Where does this concept of "favor composition over inheritance" come from?

    - by Mason Wheeler
    In the last few months, the mantra "favor composition over inheritance" seems to have sprung up out of nowhere and become almost some sort of meme within the programming community. And every time I see it, I'm a little bit mystified. It's like someone said "favor drills over hammers." In my experience, composition and inheritance are two different tools with different use cases, and treating them as if they were interchangeable and one was inherently superior to the other makes no sense. Also, I never see a real explanation for why inheritance is bad and composition is good, which just makes me more suspicious. Is it supposed to just be accepted on faith? Liskov substitution and polymorphism have well-known, clear-cut benefits, and IMO comprise the entire point of using object-oriented programming, and no one ever explains why they should be discarded in favor of composition. Does anyone know where this concept comes from, and what the rationale behind it is?

  • Converting 3 axis vectors to a rotation matrix

    - by user38858
    I am trying to get a rotation matrix (in 3dsmax) from 3 vectors that form an axis (all 3 vectors are aligned by 90 degrees each other) Somewhere I read that I could build a rotation matrix just by inserting in every row one vector at a time (source: http://renderdan.blogspot.cz/2006/05/rotation-matrix-from-axis-vectors.html) So, I built a matrix with these example vectors x-axis : [-0.194624,-0.23715,-0.951778] y-axis : [-0.773012,0.634392,0] z-axis : [-0.6038,-0.735735,0.306788] But for some reason, if I try to convert this matrix to eulerangles, I receive this rotation: (eulerAngles 47.7284 6.12831 36.8263) ... which is totally wrong, and doesn't align to my 3 vectors at all. I know that rotation is quite difficult to understand, may someone shed some light? :)

  • Unable to get screen signal after purge FGLRX

    - by Boris
    I thought that my ATI driver was not running well so I wanted to re-instal it completely. I did: sudo apt-get remove --purge fglrx* sudo apt-get remove --purge xserver-xorg-video-ati xserver-xorg-video-radeon and after a boot I wanted to intal the ATI driver BUT at the boot no more signal to my screen. Since, every time I turn on my PC it gets to purple screen and then screen shuts down ! Note that: Even if the screen is off, PC seems to be running almost well: I m still able to use my network to access data shared with NFS. Using live USB I have no screen problem. I tried to plug my screen on an alternative output but it did not work. I tried CTRL+ALT+F1 while being on purple screen but it does not do anything, screen shut down anyway. I m going to try the SHIFT thing and learn from blackscreen wiki...

  • Kill a tree, save your website? Content strategy in action, part III

    - by Roger Hart
    A lot has been written about how driving content strategy from within an organisation is hard. And that's true. Red Gate is pretty receptive to new ideas, so although I've not had a total walk in the park, it's been a hike with charming scenery. But I'm one of the lucky ones. Lots of people are involved in content, and depending on your organisation some of those people might be the kind who'll gleefully call themselves "stakeholders". People holding a stake generally want to stick it through something's heart and bury it at a crossroads. Winning them over is not always easy. (Richard Ingram has made a nice visual summary of how this can feel - Content strategy Snakes & ladders - pdf ) So yes, a lot of content strategy advocates are having a hard time. And sure, we've got a nice opportunity to get together and have a hug and a cry, but in the interim we could use a hand. What to do? My preferred approach is, I'll confess, brutal. I'd like nothing so much as to take a scorched earth approach to our website. Burn it, salt the ground, and build the new one right: focusing on clearly delineated business and user content goals, and instrumented so we can tell if we're doing it right. I'm never getting buy-in for that, but a boy can dream. So how about just getting buy-in for some small, tenable improvements? Easier, but still non-trivial. I sat down for a chat with our marketing and design guys. It seemed like a good place to start, even if they weren't up for my "Ctrl-A + Delete"  solution. We talked through some of this stuff, and we pretty much agreed that our content is a bit more broken than we'd ideally like. But to get everybody on board, the problems needed visibility. Doing a visual content inventory Print out the internet. Make a Wall Of Content. Seriously. If you've already done a content inventory, you know your architecture, and you know the scale of the problem. But it's quite likely that very few other people do. So make it big and visual. I'm going to carbon hell, but it seems to be working. This morning, I printed out a tiny, tiny part of our website: the non-support content pertaining to SQL Compare I made big, visual, A3 blowups of each page, and covered a wall with them. A page per web page, spread over something like 6M x 2M, with metrics, right in front of people. Even if nobody reads it (and they are doing) the sheer scale is shocking. 53 pages, all told. Some are redundant, some outdated, some trivial, a few fantastic, and frighteningly many that are great ideas delivered not-quite-right. You have to stand quite far away to get it all in your field of vision. For a lot of today, a whole bunch of folks have been gawping in amazement, talking each other through it, peering at the details, and generally getting excited about content. Developers, sales guys, our CEO, the marketing folks - they're engaged. Will it last? I make no promises. But this sort of wave of interest is vital to getting a content strategy project kicked off. While the content strategist is a saucer-eyed orphan in the cupboard under the stairs, they're not getting a whole lot done. Of course, just printing the site won't necessarily cut it. You have to know your content, and be able to talk about it. Ideally, you'll also have page view and time-on-page metrics. One of the most powerful things you can do is, when people are staring at your wall of content, ask them what they think half of it is for. Pretty soon, you've made a case for content strategy. We're also going to get folks to mark it up - cover it with notes and post-its, let us know how they feel about our content. I'll be blogging about how that goes, but it's exciting. Different business functions have different needs from content, so the more exposure the content gets, and the more feedback, the more you know about those needs. Fingers crossed for awesome.

  • Does software testing methodology rely on flawed data?

    - by Konrad Rudolph
    It’s a well-known fact in software engineering that the cost of fixing a bug increases exponentially the later in development that bug is discovered. This is supported by data published in Code Complete and adapted in numerous other publications. However, it turns out that this data never existed. The data cited by Code Complete apparently does not show such a cost / development time correlation, and similar published tables only showed the correlation in some special cases and a flat curve in others (i.e. no increase in cost). Is there any independent data to corroborate or refute this? And if true (i.e. if there simply is no data to support this exponentially higher cost for late discovered bugs), how does this impact software development methodology?

  • Keyring Password, Unity in 11.10

    - by Collin Owens
    Login to 11.10 I input my password and shortly afterward I am asked for a keyring password. I realize that I was asked for this during installation (second time lucky!) and I did enter a password (what a mistaka to maka). This now entails my having to input the keyring password on every boot up! Looking at previous answers it would seem that the applications - accesories - password and encryption keys - was the suggested route. However I assume that was in Gnome (At this stage I look back in fondness!!!) Certainly, I don't get the same route in Unity! I saw a reference to seahorse in a terminal - but this results in several error reports and a sub windows which does not seem to open. The objective in this exercise is to log in using the login password and not also the keyring password! any help would be appreciated - thank you

  • Is the term "web portal" obselete?

    - by John Hamelink
    Firstly, sorry if this is the wrong place: I've looked at all the programming-related boards and this one seems like the best fit - correct me if I'm wrong. My boss uses the term "portal" for the project I work on all the time. To me, the word makes me think of Yahoo in the late 90s. Does the word "portal" have old-school connotations, or is it just me? Do you think it's ok to use it, and not drag our client's perception of the product down into the middle-ages? Or again, am I just being weird?

  • Flash animations doesn't work

    - by sosen
    I have a following problem: I have Ubuntu 12.04 installed on my Athlon 1800+ + 1 GB RAM + Nvidia Geforce4 MMX 440 (pretty old configuration) and everything works just fine except Flash Player in my Web browser (tried Firefox and Chromium). Instead of movie/animation, I get blank space. I updated my system via update manager, checked the plugins (everything OK), installed and updated flash player one more time, installed Ubuntu restricted extras, tried Firefox's Flash Aid, even tried Youtube Html 5 (still the same result)... Please, help me! I enjoy working with Linux and Ubuntu is the first that works for me well (after Open Suse and Fedora) but I have no idea what is wrong now...

  • 6 Ways Windows 8 Is More Secure Than Windows 7

    - by Chris Hoffman
    Whatever you think of it, Windows 8 isn’t just a new interface slapped on top of Windows 7. Windows 8 has seen a lot of security improvements, including an integrated antivirus, an application reputation system, and protection from boot-time rootkits. There are also quite a few low-level security improvements under the hood. Microsoft hasn’t spelled out all of them, but Windows 8 manages memory in a more secure way and includes features that make security vulnerabilities harder to exploit.

  • OpenGL 2D Depth Perception

    - by Stephen James
    This is the first time i have ever commented on a forum about programming, so sorry if I'm not specific enough. Here's my problem: I have a 2D RPG game written in Java using LWJGL. All works fine, but at the moment I'm having trouble deciding what the best way to do depth perception is. So , for example, if the player goes in front of the tree/enemy (lower than the objects y-coordinate) then show the player in front), if the player goes behind the tree/enemy (higher than the objects specific y-coordinate), then show the player behind the object. I have tried writing a block of code to deal with this, and it works quite well for the trees, but not for the enemies yet. Is there a simpler way of doing this in LWJGL that I'm missing? Thanks :)

  • When to mark a user story as done in scrum?

    - by Saeed Neamati
    There is a notion in scrum that emphasizes delivery of workable units at the end of each sprint. Each workable unit also maps directly of indirectly to a user story and when in new sprint PO introduces new PBI (new user stories), this means that practically team can't always go back to previous user stories to do the rest of the job, which in turn means that when you implement a user story, you should do it as complete as it's known to the team in that time, and you shouldn't forget anything (something like "I'm sorry, I've forgotten to implement validation for that input control" or "I didn't know that cross-browser check is part of the user story"). At the other hand, test, backward compatibility, acceptance criteria, deployment and more and more concepts come after each user story. So, when can team members know that the user story is done completely, not just for demo, and start a new one?

  • How do I consistently re-size my game window and elements?

    - by Milo
    In my 2D game, I have a flow layout. Inside the flow layout are tables. I have a slider that lets the user make the tables larger or smaller. This makes the background larger or smaller too. Everything should scale proportionally which means the background should stay at the same position when I make things larger, and it almost does. When the scrollbar is at 0, it does exactly this. As the scrollbar gets further down problems arise. I'll toggle the slider maybe 3 times and on the fourth time, the background jumps a little lower on the Y axis. In order to be efficient, I only start rendering the background near the parent of the flow layout. Here it is: void LobbyTableManager::renderBG( GraphicsContext* g, agui::Rectangle& absRect, agui::Rectangle& childRect ) { int cx, cy, cw, ch; g->getClippingRect(cx,cy,cw,ch); g->setClippingRect(absRect.getX(),absRect.getY(),absRect.getWidth(),absRect.getHeight()); float scale = 0.35f; int w = m_bgSprite->getWidth() * getTableScale() * scale; int h = m_bgSprite->getHeight() * getTableScale() * scale; int numX = ceil(absRect.getWidth() / (float)w) + 2; int numY = ceil(absRect.getHeight() / (float)h) + 2; float offsetX = m_activeTables[0]->getLocation().getX() - w; float offsetY = m_activeTables[0]->getLocation().getY() - h; int startY = childRect.getY(); if(moo) { std::cout << "S=" << startY << ","; } int numAttempts = 0; while(startY + h < absRect.getY() && numAttempts < 1000) { startY += h; if(moo) { std::cout << startY << ","; } numAttempts++; } if(moo) { std::cout << "\n"; moo = false; } g->holdDrawing(); for(int i = 0; i < numX; ++i) { for(int j = 0; j < numY; ++j) { g->drawScaledSprite(m_bgSprite,0,0,m_bgSprite->getWidth(),m_bgSprite->getHeight(), absRect.getX() + (i * w) + (offsetX),absRect.getY() + (j * h) + startY,w,h,0); } } g->unholdDrawing(); g->setClippingRect(cx,cy,cw,ch); } The numeric problem seems to be in the value of startY. I outputted startY figuring out its value: As you can see here, this is me only zooming in, pay attention to the final number before the next s=. You'll notice that, what should happen is, the numbers should be linear, ex: -40, -38, -36, -34, -32, -30, etc. As you'll notice, the start numbers linearly correlate ex: 62k, 64k, 66k, 68k, 70k etc.. but the end result is wrong every third or 4th time. Here is most of the resize code: void LobbyTableManager::setTableScale( float scale ) { scale += 0.3f; scale *= 2.0f; agui::Gui* gotGui = getGui(); float scrollRel = m_vScroll->getRelativeValue(); setScale(scale); rescaleTables(); resizeFlow(); if(gotGui) { gotGui->toggleWidgetLocationChanged(false); } updateScrollBars(); float newVal = scrollRel * m_vScroll->getMaxValue(); if((int)(newVal + 0.5f) > (int)newVal) { newVal++; } m_vScroll->setValue(newVal); static int x = 0; x++; moo = true; //std::cout << m_vScroll->getValue() << std::endl; if(gotGui) { gotGui->toggleWidgetLocationChanged(true); } if(gotGui) { gotGui->_widgetLocationChanged(); } } void LobbyTableManager::valueChanged( agui::VScrollBar* source,int val ) { if(getGui()) { getGui()->toggleWidgetLocationChanged(false); } m_flow->setLocation(0,-val); if(getGui()) { getGui()->toggleWidgetLocationChanged(true); getGui()->_widgetLocationChanged(); } }
