  • Jave JIT compiler compiles at compile time or runtime ?

    - by Tony
    From wiki: In computing, just-in-time compilation (JIT), also known as dynamic translation, is a technique for improving the runtime performance of a computer program. So I guess JVM has another compiler, not javac, that only compiles bytecode to machine code at runtime, while javac compiles sources to bytecode,is that right?

  • Is displayMetrix xdpi and ydpi accurate?

    - by oddvark
    Can the xdpi and ydpi settings be relied upon to accurately represent the physical pixels in once inch of screen space? I need this to be accurate for some display code I'm writing. I realize the documention says that this is the case, but I need to know if individual handsets get this right MOST OF THE TIME. I know I can alternately use "densitiy" which will give me 120, 160, 240 steps of DPI, but an exact dpi would be much better. Thanks!

  • C# multiple asynchronous HttpRequest with one callback

    - by aepheus
    I want to make 10 asynchronous http requests at once and only process the results when all have completed and in a single callback function. I also do not want to block any threads using WaitAll (it is my understanding that WaitAll blocks until all are complete). I think I want to make a custom IAsyncResult which will handle multiple calls. Am I on the right track? Are there any good resources or examples out there that describe handling this?

  • Help with data retrieval MACRO

    - by Andrei Ciobanu
    Hello, given the following structure: struct nmslist_elem_s { nmptr data; struct nmslist_elem_s *next; }; typedef struct nmslist_elem_s nmslist_elem; Where: typedef void* nmptr; Is it possible to write a MACRO that retrieves the data from the element and cast it to the right type: MACRO(type, element) that expands to *((type*)element->data). For example for int, i would need something like this: *((int*)(element->data)) .

  • Outlook Folder Browse Dialog???

    - by Ike
    Hello there, I'm hoping someone could help me with a quick point in the right direction. ALL I NEED is the Outlook folder browser dialog call. I am developing some plugins for Outlook using C# and this is a crucial part for both plugins. Hopefully, it is like a standard DialogResult that passes back folder information (selected folder) so that I can use this info for further processing. Can anyone help me? Thanks in advance.

  • nginx - redirect a certain path to another domain

    - by Eli
    Hey there. I am very unfamiliar with nginx, as a forewarning, and also can't find any actual references on the regex system they use. So right now it's a black box to me. All I want to do is redirect a user trying to go to www.mydomain.com/mydirectory/X to www.myotherdomain.com/X . Seems like I should be using the rewrite command but the syntax of the regex is eluding me. Thanks in advance.

    I list products on my homepage and on a company details page. I use the exact same HTML, but for some reason the product appears different: The productname is "Artikel 1".

But here: http://www.zorgbeurs.nl/bedrijven/76/mymedical the green price area is all the way at the bottom of the page. Why?

  • Something like PPerl for Ruby?

    - by sal
    I've used PPerl for deamon like processes. This program turns ordinary perl scripts into long running daemons, making subsequent executions extremely fast. It forks several processes for each script, allowing many proceses to call the script at once. Does anyone know of something like this for ruby? Right now I am planing on using a wrapper around curl to call a REST WebService written in Sinatra running on JRuby. I'm hoping there is a simpler option.

  • Tile Collision Question

    - by Alu
    Hey guys, I'm working on tile collision. Currently, I just draw the tile map the normal way (two for loops) and there is no scrolling. Right now, to check if my player is over a tile, I use tileX = (int)person1v.X / 16; tileY = (int)person1v.Y / 16; However, I want to detect collision before I hit the tile so it could act as a wall. How do I detect collision before even making the move?

  • Activation Function, Initializer function, etc, effects on neural networks for face detection

    - by harry
    There's various activation functions: sigmoid, tanh, etc. And there's also a few initializer functions: Nguyen and Widrow, random, normalized, constant, zero, etc. So do these have much effect on the outcome of a neural network specialising in face detection? Right now I'm using the Tanh activation function and just randomising all the weights from -0.5 to 0.5. I have no idea if this is the best approach though, and with 4 hours to train the network each time, I'd rather ask on here than experiment!
