  • Drupal Query builder

    - by Rimian
    I quite often use Drupal's Views Module to build SQL that I paste into my code. It understands the Drupal database schema quite well. Is there a module that would give me this functionality or can I factor this out of Views?

  • Help understanding the Single Responsibility Principle

    - by user204588
    I'm trying to understand what a responsibility actually is so I want to use an example of something I'm currently working on. I have a app that imports product information from one system to another system. The user of the apps gets to choose various settings for which product fields in one system that want to use in the other system. So I have a class, say ProductImporter and it's responsibility is to import products. This class is large, probably too large. The methods in this class are complex and would be for example, getDescription. This method doesn't simply grab a description from the other system but sets a product description based on various settings set by the user. If I were to add a setting and a new way to get a description, this class could change. So, is that two responsibilities? Is there one that imports products and one that gets a description. It would seem this way, almost every method I have would be in it's own class and that seems like overkill. I really need a good description of this principle because it's hard for me to completely understand. I don't want needless complexity.

  • Bejeweled Blitz - How does it assert there is always a move?

    - by EvilTeach
    I have been playing Bejeweled Blitz for a while now. Yes, it is an addiction. In thinking about the game, I have observed that on some boards, the bottom runs dry (no moves) leaving only the top part of the board playable. Frequently that part of the board drys up, and one is left with moves in area cleared by the last move. The board never runs completely dry, so clearly the program is doing some sorts of calculation that allows it to choose what to drop to prevent it from running dry. I have noticed in this 'mode' that it is very common for the algorithm to drop jewels which causes more non-dry area to appear in the horizontal area. Perhaps less frequent is a drop which seems designed to open up the bottom part of the board again. So my question is "How would one go about designing an algorithm guarantee that there is always a move available.?"

  • How to merge two FBOs?

    - by DevDevDev
    OK so I have 4 buffers, 3 FBOs and a render buffer. Let me explain. I have a view FBO, which will store the scene before I render it to the render buffer. I have a background buffer, which contains the background of the scene. I have a user buffer, which the user manipulates. When the user makes some action I draw to the user buffer, using some blending. Then to redraw the whole scene what I want to do is clear the view buffer, draw the background buffer to the view buffer, change the blending, then draw the user buffer to the view buffer. Finally render the view buffer to the render buffer. However I can't figure out how to draw a FBO to another FBO. What I want to do is essentially merge and blend two FBOs, but I can't figure out how! I'm very new to OpenGL ES, so thanks for all the help.

  • The 10.6.3 os x update broke simulated key-presses for Nestopia.

    - by Lou Z.
    The iPhone app that I released is a wireless game controller, it translates touches on the device into key-presses on the networked Mac. This allowed for playing emulator (e.g. Nestopia) games using the iPhone as a controller. Of course, the day that I released it coincided with an os x update. After installing this update, the simulated key-presses no longer work in Nestopia! The crazier thing is, when I go to 'File Open' within Nestopia, I can cycle through the file list by hitting the up-arrow on my iphone controller; i.e. the simulated key-presses work in menu items, but not in the game itself. The code that I use to simulate keys is below. Given the list of changes here, can anyone identify which change would cause this problem? Thanks!! #define UP false #define DOWN true -(void)sendKey:(CGKeyCode)keycode andKeyDirection:(BOOL)keydirection{ CGEventRef eventRef = CGEventCreateKeyboardEvent(NULL, keycode, keydirection); CGEventPost(kCGSessionEventTap, eventRef); CFRelease(eventRef); }

  • Game Programming - GUIs

    - by Spencer
    I've been coding for a while now and would like to start looking into programming games. I know the industry's standard language is C++, for 3D graphics the main choice is between Direct 3D and OpenGL, but what is the most widely used GUI framework? I'm currently on a Mac so if native Windows API is the answer, then what is the cross platform choice? To be clear, I'm not looking for people's favourites but simply what the common or standard game industry's choice is so that I can learn and familiarize myself with it. Thanks, Spencer

  • How do I prepare myself for a summer of working on Python using Linux environment?

    - by Shailesh Tainwala
    Hi, I have used just Windows for programming so far. Now, I have an internship starting in two weeks and I will be using just Linux environment with Python programming language. I've installed Ubuntu on my system but have no exposure to shell scripting. I need some advice on how I can quickly learn to use the Linux terminal quickly. Any books or web resources that you can suggest? Also, is there a particular IDE that is generally preferred for Python programming on Linux, or is Vim preferred? How can I best prepare myself for the internship ahead? Thanks for taking the time.

  • 3-d game programming

    - by Ygam
    what programming language/languages do they use to produce games lik Bioware's Dragon Age Origins and some other 3-d games like Call of Duty? If I would like to do 3d-game programming, where do I start? Are there even simple tutorials for this? I would like to do 3-d game programming for PC games:)

  • Getting the executed output of an aspx page after a short delay

    - by Ankur
    Hi all, I have an aspx page which has some javascript code like <script> setTimeout("document.write('" + place.address + "');",1); </script> As it is clear from the code it will going to write something on the page after a very short delay of 1 ms. I have created an another page to get the page executed by some query string and get its output. The problem is I can not avoid the delay as simply writing document.write(place.address); will not print anything as it takes a little time to get values so if i set it in setTimeout for delayed output of 1 ms it always return me a value If I request the output from another page using System.Net.WebClient wc = new System.Net.WebClient(); System.IO.StreamReader sr = new System.IO.StreamReader(wc.OpenRead("http://localhost:4859/Default.aspx?lat=" + lat + "&lng=" + lng)); string strData = sr.ReadToEnd(); I get the source code of the document instead of the desired output can anyone help me out for either avoiding that delay or else delayed the client request ouput so that i get a desired value not the source code The js on default.aspx is <script type="text/javascript"> var geocoder; var address; function initialize() { geocoder = new GClientGeocoder(); var qs=new Querystring(); if(qs.get("lat") && qs.get("lng")) { geocoder.getLocations(new GLatLng(qs.get("lat"),qs.get("lng")),showAddress); } else { document.write("Invalid Access Or Not valid lat long is provided."); } } function getAddress(overlay, latlng) { if (latlng != null) { address = latlng; geocoder.getLocations(latlng, showAddress); } } function showAddress(r) { place = r.Placemark[0]; setTimeout("document.write('" + place.address + "');",1); //document.write(place.address); } </script> and the code on requestClient.aspx is as System.Net.WebClient wc = new System.Net.WebClient(); System.IO.StreamReader sr = new System.IO.StreamReader(wc.OpenRead("http://localhost:4859/Default.aspx?lat=" + lat + "&lng=" + lng)); string strData = sr.ReadToEnd();

  • How to avoid game rendering component circular references?

    - by CodexArcanum
    I'm working on a simple game design, and I wanted to break up my game objects into more reusable components. But I'm getting stuck on how exactly to implement the design I have in mind. Here's an example: I have a Logger object, whose job is simply to store a list of messages and render them to screen. You know, logging. Originally the Logger just held the list, and the game loop rendered it's contents. Then I moved the rendering logic into the Logger.Draw() method, and now I want to move it further into a LoggerRenderer object. In effect, I want to have the game loop call RenderAll, which will then call Logger.Render, which will in turn call the LoggerRenderer.Render and finally output the text. So the Logger needs to contain a Renderer object, but the Renderer needs access to the Logger's state (the message queue) in order to render. How do I resolve that? Should I be passing in the message queue and other state information explicitly to the Render method? Or should the game loop be calling the Renderer directly and it links back to the logger, but the RenderAll method never actually sees the logger object itself? This feels kind of like Command pattern, but I'm botching it up terribly.

  • JQuery: Push Effect?

    - by JGreig
    I'm currently using the JQuery slideDown/slideUp effect and am not accomplishing what I want. Essentially, I want to create an action where I "push" a div off the top of the browser window. Something similar to the following push effect example. How can I do this with JQuery? The problem with just using slideDown/slideUp is that the other DIV just overlaps the div I'm hiding. But instead, I want to PUSH the div I don't want visible off the top of the browser window.

  • What programming technique / practice done by you was ahead of its time?

    - by Binoj Antony
    I once built a very good web application in ASP (classic) back in 2001 and extensively used XmlHttpRequest object in it. (I was lucky that the clients were only using IE, and only IE supported this object at that time). Then later when people started talking about AJAX in 2005, It felt good to have used something ahead (or early) of its time. Well, maybe this does not qualify to be listed as something done ahead of its time. Which programming technology/technique/practice have you done that was ahead of this time. One story per answer please. The title for this question taken from an opposite question here.

  • Best commercial libraries for developing NCPDP-based systems (prescription drug related)

    - by Kaveh Shahbazian
    What are (based on experiences) best commercial libraries for developing NCPDP-based systems? Edit 2: Thanks to all for help! NCPDP (National Council for Prescription Drug Programs) is an standard for e-prescribing. It defines two formats for message transmission: binary and XML. Implementing XML is somehow easier because it is a standard format which in turn gives us more tooling options. The binary format has a very big specification and time-consuming to implement. I did not find an open source solution to work with. So I am looking for commercial alternatives. Edit 1: Please guide me; what's wrong with this question?

  • @font-face fonts only work on their own domain

    - by Ben
    I am trying to create a type of font repository for use on my websites, so that I can call to any font in the repository in my css without any other set-up. To do this I created a subdomain on which I placed folders for each font in the repository that contained the various file types for each font. I also placed a css file called font-face.css on the root of the subdomain and filled it with @font-face declarations for each of the fonts, the fonts a linked with an absolute link so that they can be used from anywhere. My issue is that it seems that I can only use the fonts on that subdomain where they are located, on my other sites the font does not show. Using firebug I determined that the font-face.css file was successfully being linked to and loaded. So why does the font not correctly load? Is there protection on the font files or something? I am using all fonts that I should be allowed to do this with, so I don't see why this is occurring. Maybe it is an apache issue, but I can download the font just fine when I link to it. Oh, and just to clarify, I am not violating any copyrights by setting this up, all the fonts I am using are licensed to allow this sort of thing. I would however like to set up a way that only I can have access to this repository of fonts but that's another project.

  • Best Static Website Generator

    - by Nick Retallack
    In the age of dynamic websites built with layouts and templates, nobody wants to write plain old repetitive static html anymore. But now that you can outsource dynamic features to services like Disqus, and you could get slashdotted/dugg/reddited at any moment, sometimes a static website is best for scalability. There are quite a few static website generators out there that let you use templates, layouts, alternative markup languages, and other new age stuff. So this question is a bit of a survey. Which do you think is the best, and why? Here are a few examples to start us off: WebGen StaticMatic Static

  • How to achieve Bing maps like InfoWindow in Google Maps?

    - by BillB
    I'm using Google Maps v3. I really like the InfoWindows found in Bing, as opposed to Google. Screenshots & functionality found here comparing the two: http://www.axismaps.com/blog/2009/07/data-probing-and-info-window-design-on-web-based-maps/ Question: How can I replicate Bing like InfoWindows while using Google Maps v3? UPDATE: To be more specific, what I like about Bing's InfoWindows include: - The pointer dynamically changes sides from left/right/bottom/top, as opposed to Google limited to only have the InfoWindow pointer on the bottom - Bing's InfoWindows use less space - You can configure Bing's InfoWindows to pop up outside of the map bounders so that you don't have to autopan the map to display the marker's InfoWindow
