  • How to execute a multiple line configure command using Mac OS X terminal?

    - by skiabox
    I am reading a nice article about upgrading php on mac os x mountain lion. At the Install part of the document the author says that the user must execute a multiple line configure command. What is the easiest way to do it, using mac os terminal? Thank you. PS : I have executed yesterday the configure command without the parameters. Can this action cause any problems with the re-execution of configure command (with parameters this time)?

  • cygwin running commands with switches when ssh in

    - by Troz123
    When I SSH into a Windows 2008 R2 box and try to run a command with switches like /cygdrive/c/directory/Reports.exe /ReportID=1 /DateRange=LastWeek the command just hangs and never finishes. I can see the Reports.exe spawn a process under the user but never finishes. If I RDP into the box open cygwin terminal and run the exact command it works. Any reason why I can't run the command when I SSH in?

  • Adding images to the html with javascript

    - by Anonymous
    I've tried some HTML DOM code from several sites, but it isn't working. It isn't adding anything. Does anyone have a working example on this? this.img = document.createElement("img"); this.img.src = "img/eqp/"+this.apparel+"/"+this.facing+"_idle.png"; src = getElementById("gamediv"); src.appendChild(this.img) But it isn't adding anything to the div. (gamediv) I've tried document.body as well, with no result. Thanks in advance.

  • Any dangers of sharing /home partition between two distros?

    - by Linux_iOS.rb.cpp.c.lisp.m.sh
    I have a laptop with a 250GB HDD. I have an existing installation of Kubuntu across three partitions (A 20GB one for /, 2GB for swap, and something like 97GB for /home). If I add another partition, use that as / for a Mint 13 install, and then use the existing /home partition as Linux Mint's home folder (different user names), are there any dangers (besides badly done partitioning, and other dumb things like that)?

  • How do I get the size of the boost buffer

    - by Anonymous
    I am trying to make an asynchronised server in visual studio and I use boost::asio::async_read(m_socket, boost::asio::buffer(m_buffer), boost::bind(&tcp_connection::handle_read, shared_from_this(), boost::asio::placeholders::error)); to get the buffer to be put in m_buffer boost::array<char, 256> m_buffer; but how do I get the size of this thing, m_buffer? size() didn't work, end() didn't work.. Any help would be fantastic. Thanks in advance.

  • Prevent Browser from Opening Download Window for CDN

    - by TheBlackBenzKid
    I use Rackspace CloudFiles CDN. Apparently the way that Akamai works (company that backs CloudFiles program) is that the mime-type is an image and will force the user to download it - I can still use the image within HTML tags like the <img src="//cdn.com/image.jpg"/> but copying it in the URL or clicking the image will always prompt the download I want to view that image within the browser - this happens with IE, Google Chrome and Firefox.

  • Unable to install some applications on windows 7 64 bit (These files can't be opened error)

    - by rzlines
    I get the following error when I try to install some application on my windows 7 64 bit system. How do I turn this off as I know that the applications that I'm installing are trusted. I have turned off windows defender and tried to tweak internet explorer security settings according to the first few google results but yet I have the same error. (I also created a new user account and tried importing new registry keys but nothing even then) How can I solve this?

  • Overriding vs Virtual

    - by anonymous
    What is the purpose of using the reserved word virtual in front of functions? If I want a child class to override a parent function, I just declare the same function such as "void draw(){}". class Parent{ public: void say(){ std::cout << "1"; }}; class Child : public Parent{public:void say(){ std::cout << "2"; } }; int main() { Child* a = new Child(); a->say(); return 0; } The output is 2. So again, why would the reserved word "virtual" be necessary in the header of say() ? Thanks a bunch.

  • How to use a variable in a function expression which is injected in a page?

    - by anonymous
    I'm trying to inject a function into a webpage via Chrome extension content script by: function inject(code) { var actualCode = '(' + code + ')();'; var script = document.createElement('script'); script.textContent = actualCode; (document.head||document.documentElement).appendChild(script); script.parentNode.removeChild(script); } var myObj = person; // myObj/person is passed in from elsewhere var fn = function() { alert(myObj.name); }; inject(fn); // myObj undefined My issue is, since fn is a function expression, I can't pass in myObj.personName. So my question is, how can I construct a function expression that includes a variable? Do I do some sort of string concatenation instead? I also tried to pass the object to the function, as follows: function inject(code, myObj) { var actualCode = '(' + code + ')(' + myObj +');'; ... But this did not work, and caused a "Uncaught SyntaxError: Unexpected identifier" error. Related: Building a Chrome Extension - Inject code in a page using a Content script

  • Is the XP VMM a bottleneck on a multi core machine?

    - by JeffV
    I have a dual Xeon hex core machine running an IO intensive application. (WinXP 32) I am seeing a hardware driver (1/2 user mode, 1/2 kernel, streaming data) that is using 6k delta page faults per second. When other applications load or allocate large amounts of memory the driver's hardware buffer gets an underrun (application not feeding it fast enough). Could this be because the kernel is only using one core to service page fault interrupts?

  • Creating a password-protected task in Windows 7

    - by Matthias
    I would like to configure a task like "child control software", so it would hibernate the pc at certain times. Is it possible to prevent modification (here: pausing) of a task through requiring the entering of the admin password to modify, EVEN THOUGH the currently-logged-in (and only) user is the admin account itself? (Do you know of any child control software that does NOT require an additional account yet is able to hibernate the system at certain times?) Thanks a lot!

  • I just can't figure out strcat.

    - by Anonymous
    I know I shouldn't be using that function, and I don't care. Last time I checked the spec for strcat, it said something along the lines of updating the first value as well as returning the same. Now, this is a really stupid question, and I want you to explain it like you're talking to a really stupid person. Why won't this work? char* foo="foo"; printf(strcat(foo,"bar")); EDIT: I don't know the difference between char[] and char*. How would I allocate a string of 255 characters? EDIT 2: OK, OK, so char[number] allocates a string of that many bytes? Makes sense. Thanks.

  • Restrict print copies on a PDF

    - by Chops
    We have a very specific use case for an application we're developing, where a user will be presented with a PDF document, which they can print off. However, we need to be able to restrict the PDF so it can only be printed off once. Does anyone know if there's a way to restrict the number of times a PDF can be printed. I'm aware the PDF spec has lots of security features, but I've not found reference to anything like this before. Many thank.

  • jQuery class selector and click()

    - by Anonymous
    I'm currently trying to get an alert to happen when something is clicked. I can get it working in jsFiddle, but not in production code: jsFiddle example that works (jQuery 1.5 loaded) HTML (in case jsFiddle is inaccessible): <!DOCTYPE HTML><html><head><title>Test</title></head> <body> <h1>25 Feb 2011</h1><h3>ABC</h3><ul> <li class="todoitem">Test&mdash;5 minutes</li> </ul> </body></html> Javascript: $(".todoitem").click(function() { alert('Item selected'); }); Non-working production example: <!DOCTYPE HTML><html><head><title>Test</title> <script src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.5.1.min.js" type="text/javascript"></script> <script type="text/javascript"> $(".todoitem").click(function() { alert('Item selected'); }); </script> </head> <body> <h1>25 Feb 2011</h1><h3>ABC</h3><ul><li class="todoitem">Test&mdash;5 minutes</li></ul> </body> </html> Safari's Inspector indicate that jQuery is being loaded correctly, so that's not the issue. As far as I can tell, these two pieces of code are essentially identical, but the latter isn't working. Can anyone see what I've done wrong?

  • How can I develop for Safari 6 without buying a mac?

    - by Urbycoz
    I've always found that just developing in Windows, and using Safari for Windows has been sufficient. However, Safari 6 has now been released, and I've got at least one user who has contacted me, saying he's experienced problems with one of my sites on his new ipad. The trouble is that Safari for Windows only goes up to 5.1.7. Do I have to go out and buy a new mac/ipad/iphone in order to test my code, or is there another way?

  • What would a new web development tool need to succeed?

    - by boost
    If one wanted to bring a new web development tool to market, what would it have to be able to do that would differentiate it enough from all the others to attract people's attention? In what areas are all the other frameworks and languages falling down, such that if a new product addressed those issues, it would stand a chance of being adopted by significant user community?

  • How to use ccache selectively?

    - by Anonymous
    I have to compile multiple versions of an app written in C++ and I think to use ccache for speeding up the process. ccache howtos have examples which suggest to create symlinks named gcc, g++ etc and make sure they appear in PATH before the original gcc binaries, so ccache is used instead. So far so good, but I'd like to use ccache only when compiling this particular app, not always. Of course, I can write a shell script that will try to create these symlinks every time I want to compile the app and will delete them when the app is compiled. But this looks like filesystem abuse to me. Are there better ways to use ccache selectively, not always? For compilation of a single source code file, I could just manually call ccache instead of gcc and be done, but I have to deal with a complex app that uses an automated build system for multiple source code files.

  • Can you password protect access to a directory (to local and networked PCs) in Windows XP Pro?

    - by Clay Nichols
    I could just compress the directory as a .zip file w/ a password (which I think would just look like a compressed folder w/ a password) but I'd like something with less overhead (i.e., none of the decompression, etc.) Any ideas? Clarification/update: I'd like to have anyone be able to access it from another computer if they know the password. I.e., I don't want them to have to log in as a different user, etc., but, rather just enter a password.
