• C: Random Number Generation - What (If Anything) Is Wrong With This

  - by raoulcousins

  For a simple simulation in C, I need to generate exponential random variables. I remember reading somewhere (but I can't find it now, and I don't remember why) that using the rand() function to generate random integers in a fixed range would generate non-uniformly distributed integers. Because of this, I'm wondering if this code might have a similar problem: //generate u ~ U[0,1] u = ( (double)rand() / ((double)(RAND_MAX)); //inverse of exponential CDF to get exponential random variable expon = -log(1-u) * mean; Thank you!

• Does the Flex rich text control have any practical value?

  - by George Edison

  Since the control emits bizzare non-standard HTML, I'm wondering if it has any practical value. The control emits font tags! How are others dealing with it? Do you do some sort of RegEx replace on the text? Or am I missing something?

• Count white spaces to the left of a line in a text file using C++

  - by insertable

  Hi all, I am just trying to count the number of white spaces to the LEFT of a line from a text file. I have been using count( line.begin(), line.end(), ' ' ); but obviously that includes ALL white spaces to the left, in between words and to the right. So basically what I'm wanting it to do is once it hits a non-space character stop it from counting the white spaces. Thanks everyone.

• Place images byte into String is not working?

  - by Proyb2

  I tried on Flex 3, facing issue with uploading JPG/PNG image, trace readUTFBytes would return correct bytes length but tmpFileContent is trucated, it would only appear to have upload just 3 characters of data to the server through PHP script which made image unusable. I have no issue for non-images format. What is wrong here? var tmpFileContent:String = fileRef.data.readUTFBytes(fileRef.data.length); Is String capable of handle bytes?

• QueryString From Shared Function

  - by Kezzer

  I'm trying to get a query string from a shared function in a code-behind model using VB.NET. You have to use HttpContext.Current.Request.QueryString("Query") in order to get it from a shared function, however doing HttpContext.Current.Request.QueryString.Count gives back 0, which obviously isn't right in my case as there's many that exist. Is there some sort of issue with using this static call from a shared function?

• How to crop scanned image using C#?

  - by ieaglle

  I have a scanned image of a book page and i need to crop this scan for leaving only page area. I tried to use AForge to detect page borders, but it doesn't work because the space which i need to crop may consist of little "light" areas (due to scanner quality) and edge detector detects borders there. That's why this is bad idea as for me. Could you recommend something? P.S. Please don't tell me to use non-free libraries.

• Mcafee PCI Compliance failing on Session ID cookie?

  - by frio80

  Hello there. I am attempting to obtain PCI compliance for my site but the Mcafee security scan has thrown a: Potential Sensitive Persistent Cookie Sent Over a Non-Encrypted (SSL) Channel Drupal (default behavior) sets a session cookie when you simply arrive at the site. This is causing the problem. Clearly, the entire site shouldn't be under SSL; plenty of other sites set session cookies like this. What gives?

• Best way for user authentication on JavaEE 6 using JSF 2.0?

  - by ngeek

  I'm wondering what the current state of art recommendation is regarding user authentication for a web application making use of JSF 2.0 (and if any components do exist) and JEE6 core mechanisms (login/check permissions/logouts) with user information hold in a JPA entity. The Sun tutorial is a bit sparse on this (only handles servlets). This is without making use of a whole other framework, like Spring-Security (acegi), or Seam, but trying to stick hopefully with the new Java EE 6 platform (web profile) if possible. Thanks, Niko

• Logical equality in C

  - by andrew cooke

  [It seems odd this doesn't exist, so apologies in advance if it's a duplicate] I want to test for logical equality in C. In other words, I want to know whether two values would be equal if both were converted in the normal way associated with logical expressions. In C99, I think that (bool)a == (bool)b gives what I want. Is that correct? What is the normal way of writing this in traditional C?

• How to decide on what hardware to deploy web application

  - by Yuval A

  Suppose you have a web application, no specific stack (Java/.NET/LAMP/Django/Rails, all good). How would you decide on which hardware to deploy it? What rules of thumb exist when determining how many machines you need? How would you formulate parameters such as concurrent users, simultaneous connections and DB read/write ratio to a decision on how much, and which, hardware you need? Any resources on this issue would be very helpful...
