  • $stdin compatibility with std::istream using swig, C++, and Ruby

    - by Kenny Peng
    I have a function in C++ that takes in an std::istream as the input: class Foo { Foo(std::istream &); } Using SWIG, I've bound it to Ruby, but Ruby's $stdin variable is fundamentally different from anything like the stream classes in C++, so I'm not sure how to either 1) expose the C++ class to Ruby in a way that I can use $stdin, or 2) convert $stdin into something the C++ class can understand. Anyone have experience with binding iostreams in C++ to Ruby? Thanks.

  • How do make my encryption algorithm encrypt more than 128 bits?

    - by Ranhiru
    OK, now I have coded for an implementation of AES-128 :) It is working fine. It takes in 128 bits, encrypts and returns 128 bits So how do i enhance my function so that it can handle more than 128 bits? How do i make the encryption algorithm handle larger strings? Can the same algorithm be used to encrypt files? :) The function definition is public byte[] Cipher(byte[] input) { }

  • Efective way to avoid integer overflow when multiplying?

    - by Jonathan
    Hi, I'm working on a hash function which gets a string as input. Right now I'm doing a loop and inside the hash (an int variable) is being multiplied by a value and then the ASCII code for the current character is added to the mix. hash = hash * seed + string[i] But sometimes, if the string is big enough there is an integer overflow there, what can I do to avoid it while maintaining the same hash structure? Maybe a bit operation included inside the loop?

  • jquery upgrade breaking existing code

    - by Victor
    I have a following event handler which worked in jquery 1.3.2 but stopped working when we upgraded to 1.8.2, still fired but doesn't do anything $('input.maskedInput').focus(function () { $(this).mask("999-999-9999"); }).blur(function () { $(this).unmask(); var numbers = $(this).val().replace(/-/g, '').replace(/_/g, ''); $(this).val(numbers.toString()); }); What could be a problem?

  • NAN mixing float and GLFloat?

    - by carrots
    This often returns NAN ("Not A Number") depending on input: #define PI 3.1415f GLfloat sineEaseIn(GLfloat ratio) { return 1.0f-cosf(ratio * (PI / 2.0f)); } I tried making PI a few digits smaller to see if that would help. No dice. Then I thought it might be a datatype mismatch, but float and glfloat seem to be equivalent: gl.h typedef float GLfloat; math.h extern float cosf( float ); Is this a casting issue?

  • Focus on textbox based on URL.

    - by Cameron
    I have two forms on one page and want to have the input boxes focused based on the URL. So for example: domain.com/Default.aspx#login and domain.com/Default.aspx#register and the javascript I have this: window.document.getElementById('<%=txtUserName.ClientID %>').focus(); window.document.getElementById('<%=txtEmail.ClientID %>').focus(); it might be better if the urls are Default.aspx?action=login actually (not sure if this effects the way in which it would work)

  • Java app makes screen display unresponsive after 10 minutes of user idle time

    - by Ross
    I've written a Java app that allows users to script mouse/keyboard input (JMacro, link not important, only for the curious). I personally use the application to automate character actions in an online game overnight while I sleep. Unfortunately, I keep coming back to the computer in the morning to find it unresponsive. Upon further testing, I'm finding that my application causes the computer to become unresponsive after about 10 minutes of user idle time (even if the application itself it simulating user activity). I can't seem to pin-point the issue, so I'm hoping somebody else might have a suggestion of where to look or what might be causing the issue. The relevant symptoms and characteristics: Unresponsiveness occurs after user is idle for 10 minutes User can still move the mouse pointer around the screen Everything but the mouse appears frozen... mouse clicks have no effect and no applications update their displays, including the Windows 7 desktop I left the task manager up along the with the app overnight so I could see the last task manager image before the screen freezes... the Java app is at normal CPU/Memory usage and total CPU usage is only ~1% After moving the mouse (in other words, the user comes back from being idle), the screen image starts updating again within 30 minutes (this is very hit and miss... sometimes 10 minutes, sometimes no results after two hours) User can CTRL-ALT-DEL to get to Windows 7's CTRL-ALT-DEL screen (after a 30 second pause). User is still able to move mouse pointer, but clicking any of the button options causes the screen to appear to freeze again On some very rare occasions, the system never freezes, and I come back to it in the morning with full responsiveness The Java app automatically stops input scripting in the middle of the night, so Windows 7 detects "real" idleness and turns the monitors into Standby mode... which they successfully come out of upon manually moving the mouse in the morning when I wake up, even though the desktop display still appears frozen Given the symptoms and characteristics of the issue, it's as if the Java app is causing the desktop display of the logged in user to stop updating, including any running applications. Programming concepts and Java packages used: Multi-threading Standard out and err are rerouted to a javax.swing.JTextArea The application uses a Swing GUI awt.Robot (very heavily used) awt.PointerInfo awt.MouseInfo System Specs: Windows 7 Professional Java 1.6.0 u17 In conclusion, I should stress that I'm not looking for any specific solutions, as I'm not asking a very specific question. I'm just wondering if anybody has run into a similar problem when using the Java libraries that I'm using. I would also gladly appreciate any suggestions for things to try to attempt to further pinpoint what is causing my problem. Thanks! Ross PS, I'll post an update/answer if I manage to stumble across anything else while I continue to debug this.

  • How can I securely check if a username is already taken?

    - by Geo
    I have a form where someone can create a new user. I'd like to add some AJAX to check if a username is taken, as soon as the input field loses focus. I'm not really sure how to go about this, as this could pave the way to bruteforce attack, since you could check for any username and see whether or not it exists. Any suggestions?

  • Wordpress as CMS, Without Using It As Website Platform

    - by swt
    What is the best method, if there is one, of using Wordpress as a CMS for users to input data while not actually building the website on the Wordpress platform? One possible solution I've found is using a PHP class called "WPGet" (http://peter.upfold.org.uk/projects/wpget) which fetches directly from the database.

    Given: fruitid('Apple', 'Granny Smith', 1). fruitid('Apple', 'Cox', 2). fruitid('Pear', 'Bartlett', 3).

  • shipping and handling fee calculation

    - by Newb
    Here is the question: Many companies normally charge a shipping and handling fee for purchases. Create a Web page that allows a user to enter a purchase price into a text box - include a JavaScript function that calculates shipping and handling. Add functionality to the script that adds a minimum shipping and handling fee of $1.50 for any purchase that is less than or equal to $25.00. For any orders over $25.00, add 10% to the total purchase price for shipping and handling, but do not include the $1.50 minimum shipping and handling fee. After you determine the total cost of the order (purchase plus shipping and handling), display it in an alert dialog box. I am beginner at JavaScript and struggling to get my code to work. It does display an alert box with the value entered by the user but doesn't add anything. Although, I don't know why the formula doesn't work. Please help. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Calculating Shipping & Handling</title> <script type="text/javascript"> /* <![CDATA[ */ var price=[]; var shipping=[]; var total=price+shipping; function calculateShipping(){ if (price <= 25){ shipping = (price + 1.5); } else { shipping = (price * 10 / 100); } window.alert("The purchase price with shipping is " + document.calculate.ent.value); } /* ]]> */ </script> </head> <body> <form name ="calculate" action="" > <p>Enter Purchase Price</p> <input type="text" name="ent" > <input type="button" name="button" value="Submit" onClick="calculateShipping()" /> </form> </body> </html>

How could I dynamically update the query to include ('blue', 'dogs') in union and intersection queries?
