  • How to replace href using javascript regex in Firefox?

    - by Andrei
    I try to change some links on a webpage using the following code for jQuery on Rails $(function () { $('#lesson a').live('click', function () { $.getScript(this.href.replace(/^(http...[^\/]+)?\/+(.*)$/,'/ajax/\\$2')); return false; }); }) This trick works for Chrome and Safari, but fails (nothing happens on click) for Firefox and Opera. What can be wrong with the code? EDIT1: The webpage contains: <div id="lesson"> <a href="/subj1">Subject 1</a> ... </div> On click, a browser (i.e. Firefox and Opera) should make an ajax-request of /ajax/subj1.

  • How can I make the boostrap js carousel automatically cycle as soon as the page loads?

    - by Jonathan Larkin
    Using bootstrap.js version 2.02 I'm trying to get the Twitter Bootstrap Carousel to automatically cycle as soon as someone visits my site. Right now, the auto cycling works only after you click one of the cycle buttons at least once. I want the carousel to begin cycling at the interval right away. Does anyone know how to do this? My site is hotairraccoon.com You'll see how after you click the carousel once, it begins to cycle every 5 seconds or so, but I don't want the click to be required to reveal carousel content. Thanks!

  • How to I get raw 'mouse' events with touch screens on Windows Vista/7?

    - by Emil
    Does anyone have a clue how to completely disable the touch/tablet 'magic' introduced in Windows Vista? When I follow the steps on http://msdn.microsoft.com/en-us/library/bb969148(VS.85).aspx (both SetProp disable and WM_TABLET_QUERYSYSTEMGESTURESTATUS override) I succeed in stopping windows from treating press-and-hold as a right-click (it correctly gives me a WM_LBUTTONDOWN), but it also gives me a premature WM_LBUTTONUP (before I really let go of the screen). And there is also another problem: a click followed by a drag (down, up, down, move) is treated as a double-click (down, up, down, up, move). These issues occur with two very different touch screens (so it is not a hardware problem), and it never used to happen with Windows XP. This really bugs me. I would much rather have the raw input events like you have for normal mouse clicks. Any ideas?

  • Why does the CPU window always appear when trying to debug my project after a rebuild in Delphi 2010

    - by James
    Hi, Whenever I rebuild my application and try to step into a break-point the CPU window always appears. From what I understand the CPU window appears when DCU does not match up with the source file, however, in my case the DCU's are defintely being re-compiled and there are no old ones lying around or anything like that. The strange thing here is if I close down the application and re-open the project, place the breakpoint and run it works fine. I can even modify files and just press F9 to run the project and it works fine....it only seems to be when I rebuild the project (via IDE Project menu or the project context menu) that this CPU window never breaks into the source (even though it can find it!). I also noticed in the callstack a unit called Generics is always the top of the stack, never the unit my break point is in, this is no way related to where my break point is. Any ideas?

  • Pop up window dialogs

    - by Omega
    In Cocoa, my application's main window has a button. How can I make it so when you click it, a new window will be generated and set focus to such window so that the main window can not be clicked or interacted with at all? This new window will have a textfield and a submit button. You click it and the window is supposed to close and send the textfield's data back to the main window (and it will recover focus as well). I found this: How to open a new window on button click in Cocoa Mac Application? But the answer doesn't seem to be working for me. The function showWindow doesn't seem to be recognized...

  • Detecting coincident subset of two coincident line segments

    - by Jared Updike
    This question is related to: How do I determine the intersection point of two lines in GDI+? (great explanation of algebra but no code) How do you detect where two line segments intersect? (accepted answer doesn't actually work) But note that an interesting sub-problem is completely glossed over in most solutions which just return null for the coincident case even though there are three sub-cases: coincident but do not overlap touching just points and coincident overlap/coincident line sub-segment For example we could design a C# function like this: public static PointF[] Intersection(PointF a1, PointF a2, PointF b1, PointF b2) where (a1,a2) is one line segment and (b1,b2) is another. This function would need to cover all the weird cases that most implementations or explanations gloss over. In order to account for the weirdness of coincident lines, the function could return an array of PointF's: zero result points (or null) if the lines are parallel or do not intersect (infinite lines intersect but line segments are disjoint, or lines are parallel) one result point (containing the intersection location) if they do intersect or if they are coincident at one point two result points (for the overlapping part of the line segments) if the two lines are coincident

  • Eclipse - Ouline View - Turn Off Filtering

    - by Ibolit
    Hi. I recently installed Eclipse on my new computer, and this installation somewhat filters the class members. I think it is somehow related to the Outline, but i couldn't find any settings related to it. The thing is that when i, for example, have an error in a method, and click on the little red square on the margin, eclipse shows me only that method, and nothing else. When i then click on the class name in the outline panel, eclipse shows me the class without import declarations. I can, of course, click on the import declarations in the outline panel, but then i get only them. When I want to jump to the declaration of some method by command-clicking that method's name, I again get only that method on the screen. It is really annoying. Can anyone please help me fix it? Best regards,Timofey.

  • Which kind of method signature do you prefer and why?

    - by devoured elysium
    Ok, this is probably highly subjective but here it comes: Let's assume I'm writing a method that will take a printscreen of some region of the screen. Which method signature would you prefer and why? Bitmap DoPrintScreen(int x, int y, int width, int height); Bitmap DoPrintScreen(Rectangle rect); Bitmap DoPrintScreen(Point point, Size size); Other Why? I keep seeing myself repeatedly implementing both 1) and 2) (redirecting one of them to the other) but I end up usually just using one of them, so there really is no point in having both. I can't decide which would be better. Maybe I should use the signature that looks the most with the method I'll be calling to make the printscreen?

  • .htaccess causes links on page to try an open a BIN file?

    - by user1796820
    My friend's site which I agree to tech-advise, is psychtalkonline.com. You can go check it out, it's an anonymous forum (miniBBS) running Apache on Unix. I at first had a problem with mod_rewrite but then I uploaded the .htaccess file. However, that seemed to cause problems. If you click on any link, you will get a pop-up saying "You have chosen to open which is a BIN file". If you click the source code, and click on the links in the source code, you will see that it goes to the BIN file. I'm not really sure what's going on. I really would appreciate some help. Thanks.

  • Is Ubuntu recognizing and/or using my NVIDIA graphics card?

    - by user212860
    This is my first post here, and I'm pretty new to Ubuntu/Linux. I currently have no other OS except for Ubuntu 13.10. (I used to have Win7 until i got a new terabyte hard drive). My current PC build, if any of this helps: CPU: Intel i5 quad-core Graphics: NVIDIA GeForce GTX 650 RAM: 8 GB HDD: 1 TB SATA 3 Motherboard: MSi Z77 A-G41 OS Ubuntu 13.10 So I recently installed Ubuntu 13.10 and put Steam on it, and I'm seeing that my games run a lot slower than they did when I had Win7. I figured it was a graphics problem, so I checked System Settings Details Overview. It says in "Graphics" that I have "Gallium 0.4 on NVE7" (don't really know what that is). Does this mean that Ubuntu is not using my graphics card? In System Settings Software & Updates Additional Drivers, it clearly shows like this: NVIDIA Corporation: GK107 [GeForce GTX 650] -This device is using an alternative driver (And then it shows a list of drivers that I can switch back and forth to) So this is a bit confusing. In Software and Updates, it clearly shows that I have my NVIDIA card installed, and that I have a driver selected for it. But in System Settings, it shows I have some Gallium 0.4 thing. I had done a bit of research, and ended up typing command: "lspci|grep VGA" in the Terminal. It showed this in response: VGA compatible controller: NVIDIA Corporation GK107 [GeForce GTX 650] (rev a1) The Terminal seems to recognize my graphics card. What it looks like to me, is that I don't have the proper driver, and I might be using my CPU's integrated graphics. When I switch around which driver I am using in that list, it still does not see my card in System Settings. Some of the drivers in the list give me some sort of OpenGL error when I try to run a game. It might just be that my games are running slow because the game developers have not optimized it for Ubuntu that well. However, that still doesn't take away from the fact that System Settings is not showing my NVIDIA card. TL;DR Version: How do I know if my video card is being recognized/used? If my video card is not being used, what is the best way fix that? Please make your answers easy to understand. I do not mind wordy responses, as long as I can follow what you're saying. Any help would be greatly appreciated! Thanks, Jabber5

  • Bouncing a ball off a surface

    - by Sagekilla
    Hi all, I'm currently in the middle of writing a game like Breakout, and I was wondering how I could properly bounce a ball off a surface. I went with the naive way of rotating the velocity by 180 degrees, which was: [vx, vy] -> [-vy, vx] Which (unsurprisingly) didn't work so well. If I know the position and veocity of the ball, as well as the point the ball would hit (but is going to instead bounce off of) how can I bounce it off that point? I don't need any language specific code. If anyone could provide a small, mathematical formula on how to properly do this that would work fine for me. I also need this to work with integer positions and velocity (I can't use floating point anywhere). Thanks!

  • Visual Studio IDE - how do you quickly find the implementation(s) of an interface's method?

    - by Jess
    Is there a quick way to find all of the implementations of, not references to, an interface's method/property/etc? Here's some sample code: public class SomeClass : IBaseClass { public Int32 GetInt() { return 1; } } public interface IBaseClass { public Int32 GetInt(); } public class SomeOtherClass { ISomeClass _someClass; private TestMethod() { _someClass = new SomeClass(); _someClass.GetInt(); } } I want to quickly get to SomeClass.GetInt() while reviewing SomeOtherClass.TestMethod(). If I right click on _someClass.GetInt() and click 'Go To Definition', it takes me to the interface. If I click 'Find All References', I could potentially see a list of all uses ... not just the classes that implement the GetInt() method. Is there a faster way to find this? Any tips from other developers? We are using D.I. for most of our dependencies, which means that tracing through deeply nested code takes forever.

  • Design Better, Rich Internet Applications

    As you know, Rich Internet Applications are web-based software programs that behave and operate like a desktop application. These may be delivered through a site-specific browser, a browser plug-in, or through other methods; they are especially useful for massively-multiplayer online role-playing games (MMORPGs). RIA training can be especially useful in learning the tools that are used for designing and developing these increasingly-necessary additions to Internet Web Sites.

  • How to change the name dynamicaly using jQuery grid

    - by kumar
    I have jQuery grid with user data; my first column is ID: $("#table").click(function(e) { var row = jQuery(e.target).parent(); Name = row.attr("id"); Friends(Name); }); Now when I click on the row I am getting the ID value. I am passing this ID to one function to display it. It always shows the name of the first row - it isn't changing for every row click... Any ideas?

  • C++0x optimizing compiler quality

    - by aaa
    hello. I do some heavy numbercrunching and for me floating-point performance is very important. I like performance of Intel compiler very much and quite content with quality of assembly it produces. I am thinking at some point to try C++0x mainly for sugar parts, like auto, initializer list, etc, but also lambdas. at this point I use those features in regular C++ by the means of boost. How good of assembly code do compilers C++0x generate? specifically Intel and gcc compilers. Do they produce SSE code? is performance comparable to C++? are there any benchmarks? My Google search did not reveal much. Thank you.

  • NavigateUrl="#" becomes href="SubFolder/#"??

    - by jamietre
    This isn't exactly Fermat's last theorem, but it keeps coming back to annoy me like an unpaid phone bill from college. Sometimes I want to create a HyperLink that does not cause a postback, so I want the target url to be #. When the markup happens to be from a UserControl in a subfolder, / |- Home.aspx (uses UC.ascx) |- Sub |- UC.ascx the URL is rewritten with a relative path, e.g. <asp:HyperLink runat="server" NavigateUrl="#" >Click Me!</asp:HyperLink> becomes <a href="SubFolder/#">Click Me!</a> Which is, unfortunately, wrong. Obviously I can get around this by not using a server control, but it seems stupid. Can this be avoided? The point here is I will add a click event with jQuery or in code-behind, and I never want it to cause a postback, but I want it to be a hyperlink for CSS reasons.

  • PropertyUtils performance

    - by mR_fr0g
    I have a problem where i need to walk through an object graph and pick out a particular property value. My original solution caches a linked list of property names that need to be applied in order to get from point A to point B in the object graph. I then use apache commons PropertyUtils to iterate through the linked list calling getProperty(Object bean, String name) until i have reached point B. My question is around how this will perform compared to perhaps cahing the Method objects for each step. What is propertyUtils doing under the bonnet? Is it doing a lot of reflection / heavy lifting?

  • Breathing for game/movie characters

    - by dtldarek
    Breathing (the movement of chest and face features): I'd like to ask if it is hard to model and whether it is computationaly expensive. I recently noticed the great effect it has in Madagascar 3 movie, but (please, correct me if I am wrong) don't remember seeing it in any games (except maybe steam cloud in cold/winter setting) and very few animated movies does that to noticable degree (e.g. when it is necessary by the plot or situation). I'd greatly appreciate answers from both movie graphics and game graphics perspective.

  • Determining if two rays intersect

    - by Faken
    I have two rays on a 2D plane that extend to infinity but both have a starting point. They are both described by a starting point and a vector in the direction of the ray extending to infinity. I want to find out if the two rays intersect but i don't need to know where they intersect (its part of a collision detection algorithm). Everything i have looked at so far describes finding the intersection point of two lines or line segments. Anyone know a fast algorithm to solve this?
