  • AES and CBC in PHP

    - by Kane
    I am trying to encrypt a string in php using AES-128 and CBC, but when I call mcrypt_generic_init() it returns false. $cipher = mcrypt_module_open(MCRYPT_RIJNDAEL_128, '',MCRYPT_MODE_CBC, ''); $iv_size = mcrypt_enc_get_iv_size($cipher); $iv = mcrypt_create_iv($iv_size, MCRYPT_RAND); $res = mcrypt_generic_init($cipher, 'aaaa', $iv); //'aaaa' is a test key Can someone tell me why is returning 0/false? I read the php documentation and seems correct (http://us.php.net/manual/en/mcrypt.examples.php)

  • What is the correct way to create a single instance application?

    - by Nidonocu
    Using C# and WPF under .net (rather than WindowsForms or console), what is the correct way to create an application that can only be run as a single instance? I know it has something to do with some mythical thing called a mutex, rarely can I find someone that bothers to stop and explain what one of these are. The code needs to also inform the already running instance that the user tried to start a second one, and maybe also pass any command line arguments if any existed.

  • What software should i use to work with Ruby?

    - by paranoid_pedlar
    I've only ever learned to "program" with notepad when I was learning to create batch files in Windows. I would appreciate if you can explain to me the benefits of working with an IDE over a text editor or vice versa. Please don't give emotional responses or argue someone else's suggestion/advice. I use Linux primarily. Also, I would like to be able to make programs that can be used in Windows, but programmed in Linux. Thanks.

  • What is the fastest / best Base64 en/decoder for Java ?

    - by mP
    Just found the MIG Base 64 utility but its over 6 years old since its last release. It would appear to be quicker than the Apache commons equivalent but I have yet to confirm by writing up an actual test. Has anyone verified its correctness which is always a worry. If someone takes a look at the methods, please note i a referring to the non fast methods which make assumptions trading possible correctness for pure speed.

  • How to do method chaining in Java? o.m1().m2().m3().m4()

    - by Pentium10
    Maybe the title might be better, if someone knows a better one, please edit. I've seen in many Java code notation that after a method we call another, here is an example. Toast.makeText(text).setGravity(Gravity.TOP, 0, 0).setView(layout).show(); As you see after calling makeText on the return we call setGravity and so far. How can I do this with my own classes? Do I have to do anything special?

  • Guidance on creating a drawing application in Silverlight

    - by Élodie Petit
    I need help on creating an application like Visio in Silverlight, of course a much more simpler one. Just dragging and dropping shapes and connecting them is enough at this time. Can someone direct me to some resources about this? Algorithms / implementations don't need to be in C# / Silverlight. It may be enough to start with the logic behind such an application. Thanks.

  • Usability of an endless/infinite scroll

    - by Anton Gogolev
    What are pros and cons of this technique (see Softfolio for an example). Two things I personally thought of are as follows: Impossible to tell someone where an item of interest is located (like, you probably won't say "324-th row, second column") Broken navigation when you return back to an infinitely scrolled page. What else can you think of? And what do you personally think of this approach in general. Would you use this in you projects?

    - by Gbps
    I have a C++ program that takes user input for fopen in order to initiate a file write. Could someone help me find a function which will return a FILE* and use the Windows specific version of mkdir in order to create the folder structure for fopen to never fail to open a new file in the specified location because one of the folders does not exist. Thanks a bunch!

  • FOSS solution for a local machine: DNS

    - by Shyam
    Hi, I love my Mac. But I have always found that my DNS lookups are as slow, even while flushing caches and I travel over know roads on the Internet. I was wondering if someone would know something a bit more automatic/intelligent than /etc/hosts and less complex and iron forged as BIND. Thank you for your feedback and answers!
