  • Clarification needed about Python CSV file format parsing

    - by HH
    Format is like: CHINA;2002-06-25 00:00:00.000;5,60 CHINA;2002-06-26 00:00:00.000;5,32 CHINA;2002-06-27 00:00:00.000;5,31 and I try to use Python's CSV tools to parse it but cannot understand the paragraph, source: And while the module doesn’t directly support parsing strings, it can easily be done: import csv for row in csv.reader(['one,two,three']): print row Could someone clarify the line ['one,two,three']? How would you use it with format A;B;C?

  • (Pivot) tables generation

    - by Yasir Arsanukaev
    Hello. We use Excel VBA to load data using SQL, process it and generate (pivot) tables. I wonder if there any other decent alternatives. I've been thinking on PDF generation but not sure if there are handy tools to construct pivot tables. Important requirement is the ability to print data correctly, so that everything fits on the page(s). Thanks.

  • How to autodoc .Net Google code projects?

    - by Remus Rusanu
    I know how to generate html documentation using Sandcastle and similar tools. But if I want to host the project on Google code, how can I easily publish the documentation straight into the Google project Wiki pages? I can see the SVN repository has a wiki folder which I assume maps to the project Wiki pages and I guess I can make a build step to build the documentation from the autodoc tags. But is there some tool that generates wiki compatible format from the code documentation tags?

  • Freeing ImageData when deleting a Canvas

    - by user578770
    I'm writing a XUL application using HTML Canvas to display Bitmap images. I'm generating ImageDatas and imporingt them in a canvas using the putImageData function : for(var pageIndex=0;pageIndex<100;pageIndex++){ this.img = imageDatas[pageIndex]; /* Create the Canvas element */ var imgCanvasTmp = document.createElementNS("http://www.w3.org/1999/xhtml",'html:canvas'); imgCanvasTmp.setAttribute('width', this.img.width); imgCanvasTmp.setAttribute('height', this.img.height); /* Import the image into the Canvas */ imgCanvasTmp.getContext('2d').putImageData(this.img, 0, 0); /* Use the Canvas into another part of the program (Commented out for testing) */ // this.displayCanvas(imgCanvasTmp,pageIndex); } The images are well imported but there seems to be a memory leak due to the putImageData function. When exiting the "for" loop, I would expect the memory allocated for the Canvas to be freed but, by executing the code without executing putImageData, I noticed that my program at the end use 100Mb less (my images are quite big). I came to the conclusion that the putImageData function prevent the garbage collector to free the allocated memory. Do you have any idea how I could force the garbage collector to free the memory? Is there any way to empty the Canvas? I already tried to delete the canvas using the delete operator or to use the clearRect function but it did nothing. I also tried to reuse the same canvas to display the image at each iteration but the amount of memory used did not changed, as if the image where imported without deleting the existing ones...

  • How can I persuade our team to use mac as our development platform?

    - by Allen Bargi
    I'm joining a start up and there's a debate on which platform we should choose for our development; Mac, Linux or Windows? We're gonna use mainly open source tools and languages like, ruby, rails, PHP and mysql and photoshop (or something equivalent on Linux) for design. I suggested mac but they challenged me to be more persuasive. what's your idea? Help me with your persuasive arguments please.

  • VMware event hooks in .NET

    - by Henry Jackson
    I'm developing an in-house .NET application that will be run on a VM (with VMware), and want to know if there's a way to get notifications from VM system events (like suspending, resumed, etc.) Anyone know of a convenient way to do that? The virtual machine has VMware Tools installed, does that provide a .NET API for hooking events?

  • Is there a web tool framework for building a video editing/manipulation widget other than custom Fla

    - by Brandon
    I am looking to build a widget for a site which allows users to tag images from individual frames of a video file but would prefer not to have to build a custom Flash tool. Is there an existing free library or framework which simplifies things like this in a webapplication setting? Features would also involve basic video playback functionality as well as time-driven meta-data and the ability to extract images from individual video frames. Are there existing open-source web-based tools for video manipulation other than building your own custom Flash app?

  • How can I make a GUI frontend to a command line tool in OSX?

    - by bfred.it
    I'm dying to know how I can make a GUI for ffmpeg and jhead in OSX. I've been looking for a solution for a while and thought you, stackoverflow's users, could help me. Maybe you know some document I haven't come across of or, better, a tutorial to make a GUI. I love those two tools but I like the simplicity of drag/drop operations. Note: I don't need a GUI for them, I want to make one.

  • C++ RPC library suggestions

    - by Oxsnarder
    I'm looking for suggestions regarding RPC libraries implemented in C++, for C++ developers. Some requirements constraints: Should work on both linux/unix and win32 systems Be able to execute free function and class methods Hopefully written in modern C++ not 90's/java-esque C++ Be able to function over networks and hetrogenous architectures Not too slow or inefficient Hopefully provide interfaces for TR1 style std::function's et al. My example usage is to invoke the free function foo on a remote machine. ---snip--- // foo translation unit int foo(int i, int j) { return i + j; } ---snip--- ---snip--- // client side main int main() { //register foo on client and server //setup necassary connections and states int result; if (RPCmechanism.invoke("foo",4,9,result)) std::cout << "foo(4,9) = " result << std::endl; else std::cout << "failed to invoke foo(4,9)!" << std::endl; return 0; } ---snip--- Something that can achieve the above or similar would be great.

  • Understanding C++ pointers (when they point to a pointer)

    - by Stephano
    I think I understand references and pointers pretty well. Here is what I (think I) know: int i = 5; //i is a primitive type, the value is 5, i do not know the address. int *ptr; //a pointer to an int. i have no way if knowing the value yet. ptr = &i; //now i have an address for the value of i (called ptr) *ptr = 10; //go get the value stored at ptr and change it to 10 Please feel free to comment or correct these statements. Now I'm trying to make the jump to arrays of pointers. Here is what I do not know: char **char_ptrs = new char *[50]; Node **node_ptrs = new Node *[50]; My understanding is that I have 2 arrays of pointers, one set of pointers to chars and one to nodes. So if I wanted to set the values, I would do something like this: char_ptrs[0] = new char[20]; node_ptrs[0] = new Node; Now I have a pointer, in the 0 position of my array, in each respective array. Again, feel free to comment here if I'm confused. So, what does the ** operator do? Likewise, what is putting a single * next to the instantiation doing (*[50])? (what is that called exactly, instantiation?)

  • How and/or Why is Merging in GIT Better than in SVN?

    - by John
    I've heard a few places that one of the main ways distributed version control systems shine, is much better merging than traditional tools like SVN. Is this actually due to inherent differences in how the two systems work, or do specific DVCS implementations like GIT/Mercurial just have cleverer merging algorithms than SVN?

  • What can you do in C without "std" includes? Are they part of "C," or just libraries?

    - by Chris Cooper
    I apologize if this is a subjective or repeated question. It's sort of awkward to search for, so I wasn't sure what terms to include. What I'd like to know is what the basic foundation tools/functions are in C when you don't include standard libraries like stdio and stdlib. What could I do if there's no printf(), fopen(), etc? Also, are those libraries technically part of the "C" language, or are they just very useful and effectively essential libraries?
