• Does PHPUnit have some inbuilt recursive array comparison function?

  - by Ben Dauphinee

  Some of the testing I will need to do will require comparing a known array with the result I am getting from the functions I will be running. For comparing arrays recursively: Does PHPUnit have an inbuilt function? Does someone here have some code they have constructed to share? Will this be something I will have to construct on my own?

• On OSX, how do I gradient fill a path stroke?

  - by Emiel

  Using the plethora of drawing functions in Cocoa or Quartz it's rather easy to draw paths, and fill them using a gradient. I can't seem to find an acceptable way however, to 'stroke'-draw a path with a line width of a few pixels and fill this stroke using a gradient. How is this done?

• Calculating the maximum distance between elements of vector in Matlab

  - by lhahne

  Lets assume that we have a vector like x = -1:0.05:1; ids = randperm(length(x)); x = x(ids(1:20)); I would like to calculate the maximum distance between the elements of x in some idiomatic way. It would be easy to just iterate over all possible combinations of x's elements but I feel like there could be a way to do it with Matlab's built-in functions in some crazy but idiomatic way. Any ideas?

• Delphi - Differences between CompareStr and CompareString

  - by Bourgui

  Hi all, I'm hoping someone can shed some light on this for me What are the differences, in Delphi 2009, between the CompareStr (defined in SysUtils) and CompareString (from Windows API) functions? Both let you specify the locale to be used, is the Windows one simply more "complete", due to the available comparison flags? Is one consequently faster than the other? Thanks!

• MySQL Hashing Function Implementation

  - by Jonas Stevens

  I know that php has md5(), sha1(), and the hash() functions, but I want to create a hash using the MySQL PASSWORD() function. So far, the only way I can think of is to just query the server, but I want a function (preferably in php or Perl) that will do the same thing without querying MySQL at all. For example: MySQL hash - 464bb2cb3cf18b66 MySQL5 hash - *01D01F5CA7CA8BA771E03F4AC55EC73C11EFA229 Thanks!

• glGenBuffers not defined?

  - by user146780

  I'm using windows and I notice that a lot of functions are grayed out because I guess #ifdef GL_GLEXT_PROTOTYPES is not defined. One of these is the VBO extension. Should I just define GL_GLEXT_PROTOTYPES? Otherwise how else can I use VBOs since im using OpenGL32.dll (I want my application to have no dll dependencies not included in Windows by default.) Thanks

  I'm playing around with GHCi for the first time, and I'm having some trouble writing multi-line functions. My code is as follows: Prelude> :{ Prelude| let diffSquares lst = abs $ squareOfSums lst - sumOfSquares lst Prelude| where Prelude| squareOfSums lst = (fst (sumsAndSquares lst))^2 Prelude| sumOfSquares lst = snd (sumsAndSquares lst) Prelude| sumsAndSquares = foldl (\(sms,sqrs) x -> (sms+x,sqrs+x^2)) (0,0) Prelude| :} It gives the following error: <interactive>:1:142: parse error on input `=' Could someone kindly point me in the direction of what I'm missing?

• How to ANSI-C cast from unisigned int * to char *?

  - by user314290

  I want these two print functions to do the same thing: unsigned int Arraye[] = {0xffff,0xefef,65,66,67,68,69,0}; char Arrage[] = {0xffff,0xefef,65,66,67,68,69,0}; printf("%s", (char*)(2+ Arraye)); printf("%s", (char*)(2+ Arrage)); where Array is an unsigned int. Normally, I would change the type but, the problem is that most of the array is numbers, although the particular section should be printed as ASCII.

• How can the subView detect that the mainView is rotating?

  - by wolverine

  I have a mainView. To this view, I am adding a view of the same size. When the mainView(the background) rotates, its being detected but the subview doesnt have any idea about being rotated. And its functions are not even being called. Even when the program launches too, if I am in landscape mode, its the same way. How can I make the subView know that the device is being rotated?

• WSASend() with more than one buffer - could complete incomplete?

  - by Poni

  Say I post the following WSASend call (Windows I/O completion ports without callback functions): void send_data() { WSABUF wsaBuff[2]; wsaBuff[0].len = 20; wsaBuff[1].len = 25; WSASend(sock, &wsaBuff[0], 2, ......); } When I get the "write_done" notification from the completion port, is it possible that wsaBuff[1] will be sent completely (25 bytes) yet wsaBuff[0] will be only partially sent (say 7 bytes)?

• Numpy: Creating a complex array from 2 real ones?

  - by Duncan Tait

  I swear this should be so easy... Why is it not? :( In fact, I want to combine 2 parts of the same array to make a complex array: Data[:,:,:,0] , Data[:,:,:,1] These don't work: x = np.complex(Data[:,:,:,0], Data[:,:,:,1]) x = complex(Data[:,:,:,0], Data[:,:,:,1]) Am I missing something? Does numpy not like performing array functions on complex numbers? Here's the error: TypeError: only length-1 arrays can be converted to Python scalars Cheers
