  • Java Static Methods

    - by KP65
    Hello, I am wondering when to use static methods? Say If i have a class with a few getters and setters, a method or two, and i want those methods only to be invokable on an instance object of the class. Does this mean i should use a static method? e.g Obj x = new Obj(); x.someMethod or Obj.someMethod (is this the static way?) I'm rather confused!

  • Are there Java libraries to do drag and drop

    - by Kenston
    Hello. Are there open source libraries for Java to make implementation of drag and drop easier? I plan to make something like the one shown below: The program is Alice, where you can drag some elements on the left and nest them to the right. It's open source, but they did not use any libraries I think. I'm wondering if we anyone know of open source frameworks that work this way, or assist in doing complex drag and drops.

  • Dynamic graphing using Jfreechart

    - by Albinoswordfish
    Right now I'm using JFreeChart in order to create a dynamic chart. However the chart is significantly slowing down my GUI. I was just wondering, is jfreechart generally heavy in the graphics department (my computer is not fast at all). Or is there a way to configure the ChartPanel to better optimize dynamic charting.

  • Where are Riak Post-Commit Hooks run?

    - by pixelcort
    I'm trying to evaluate using Riak's Post-Commit Hooks to build a distributed, incremental MapReduce-based index, but was wondering which Riak nodes the Post-Commit Hooks actually run on. Are they run on the nodes the client used to put the commits, or on the primary nodes where the data is persisted? If it's the latter, I'm thinking I can from there efficiently do a map or reduce and put additional records from the output.

  • What should an open source representative know?

    - by Hans
    I was recently made the "open source representative" for our software team. Some of the duties include: Tracking FOSS used in our projects Propose FOSS solutions to the software team Being the intermediary between the software team and the legal department While I have some experience with FOSS, I was wondering: Where I can get a good overview of FOSS licenses? What should I be aware of when dealing with the legal department? How can I gently introduce the team to FOSS?

  • C++ Program Always Crashes While doing a std::string assign

    - by bbazso
    I have been trying to debug a crash in my application that crashes (i.e. asserts a * glibc detected free(): invalid pointer: 0x000000000070f0c0 **) while I'm trying to do a simple assign to a string. Note that I'm compiling on a linux system with gcc 4.2.4 with an optimization level set to -O2. With -O0 the application no longer crashes. E.g. std::string abc; abc = "testString"; but if I changed the code as follows it no longer crashes std::string abc("testString"); So again I scratched my head! But the interesting pattern was that the crash moved later on in the application, AGAIN at another string. I found it weird that the application was continuously crashing on a string assign. A typical crash backtrace would look as follows: #0 0x00007f2c2663bfb5 in raise () from /lib64/libc.so.6 (gdb) bt #0 0x00007f2c2663bfb5 in raise () from /lib64/libc.so.6 #1 0x00007f2c2663dbc3 in abort () from /lib64/libc.so.6 #2 0x00000000004d8cb7 in people_streamingserver_sighandler (signum=6) at src/peoplestreamingserver.cpp:487 #3 <signal handler called> #4 0x00007f2c2663bfb5 in raise () from /lib64/libc.so.6 #5 0x00007f2c2663dbc3 in abort () from /lib64/libc.so.6 #6 0x00007f2c26680ce0 in ?? () from /lib64/libc.so.6 #7 0x00007f2c270ca7a0 in std::string::assign (this=0x7f2c21bc8d20, __str=<value optimized out>) at /home/bbazso/ThirdParty/sources/gcc-4.2.4/x86_64-pc-linux-gnu/libstdc++-v3/include/bits/basic_string.h:238 #8 0x00007f2c21bd874a in PEOPLESProtocol::GetStreamName (this=<value optimized out>, pRawPath=0x2342fd8 "rtmp://127.0.0.1/mp4:pop.mp4", lStreamName=@0x7f2c21bc8d20) at /opt/trx-HEAD/gcc/4.2.4/lib/gcc/x86_64-pc-linux-gnu/4.2.4/../../../../include/c++/4.2.4/bits/basic_string.h:491 #9 0x00007f2c21bd9daa in PEOPLESProtocol::SignalProtocolCreated (pProtocol=0x233a4e0, customParameters=@0x7f2c21bc8de0) at peoplestreamer/src/peoplesprotocol.cpp:240 This was really weird behavior and so I started to poke around further in my application to see if there was some sort of memory corruption (either heap or stack) error that could be occurring that could be causing this weird behavior. I even checked for ptr corruptions and came up empty handed. In addition to visual inspection of the code I also tried the following tools: Valgrind using both memcheck and exp-ptrcheck electric fence libsafe I compiled with -fstack-protector-all in gcc I tried MALLOC_CHECK_ set to 2 I ran my code through lint checks as well as cppcheck (to check for mistakes) And I stepped through the code using gdb So I tried a lot of stuff and still came up empty handed. So I was wondering if it could be something like a linker issue or a library issue of some sort that could be causing this problem. Are there any know issues with the std::string that make is susceptible to crashing in -O2 or maybe it has nothing to do with the optimization level? But the only pattern that I can see thus far in my problem is that it always seems to crash on a string and so I was wondering if anyone knew of any issues that my be causing this type of behavior. Thanks a lot!

  • Overriding MIME Type in PHP

    - by Mr Carl
    My site is requesting a remote image which is being transferred with the wrong MIME type. I was wondering how might I override it in PHP to tell it that it's an image? I can't use header('Content-Type') because the image is being used in a HTML document. http://manga.justcarl.co.uk/N/Naruto/494/1 - one of the pages attempting to request an image... the image looks broken because it's trying to output it as html

  • ASP.NET, JQuery - Sharing regular expressions

    - by Steve
    If you have a fair number of regular expressions used by both client (javascript) and server side code (C#, vb.net) and want to store them in one place to avoid duplication, where do you store them? I could use registerscript and write out the regex as strings, but just wondering if there is something more elegant.

  • Are there any "undocumented features" in Silverlight?

    - by Sorskoot
    I was wondering if there are any features in Silverlight 2 or 3 that aren't documented or are hidden very deep in the framework? Stuff that can be very helpful in some cases, but can be a pain to find. Are there any "hidden" gems? I'm thinking about stuff you normaly don't find in tutorials and in demos. For example, finding information about the operating system the Silverlight Application is running on thru the System.OperatingSystem class.

  • VB Classes Best Practice - give all properties values?

    - by Becky Franklin
    Sorry if this is a bit random, but is it good practice to give all fields of a class a value when the class is instanciated? I'm just wondering if its better practice to have a constuctor that takes no parameters and gives all the fields default values, or whether fields that have values should be assigned and others left alone until required? I hope that makes sense, Becky

  • Is there an API or SDK for TomTom satellite navigation devices that would let me access them from Wi

    - by jammycakes
    I was given a TomTom satellite navigation device (XL 30) for Christmas and I've been wondering recently if it is possible to use it as a location sensor for my own programs on my (Windows 7) laptop. Does anyone know if there is a published API which would allow me to do this? More specifically, how can I query it for my current location (latitude, longitude, and, if possible, altitude?)

I was wondering if there are any Ant or Apache Ivy gurus around that could give some input. The Git Project is Located Here And the Project HomePage here

  • preg_replace only part of match

    - by Tony Vipros
    Hi, I'm using preg_replace to create urls for modrewrite based paging links. I use: $nextURL = preg_replace('%/([\d]+)/%','/'.($pageNumber+1).'/',$currentURL); which works fine, however I was wondering if there is a better way without having to include the '/' in the replacement parameter. I need to match the number as being between two / as the URLs can sometimes contain numbers other than the page part. These numbers are never only numbers however, so have /[\d]+/ stops them from getting replaced.

  • fake python modules via symlinks: on windows?

    - by eudoxos
    I have several compiled python modules; they are put into a single .so (to avoid runtime linking, there are cross-module symbol dependencies), but a number of symlinks points to this .so: libfoo.so -> liball.so libbar.so -> liball.so liball.so This way, I can do import foo (Python will call initfoo() defined in liball.so) or import bar (calls initbar()). I am wondering if this approach will work on Windows?

    - by Steve Griff
    Hi there folks, I'm researching the prospect of incorporating a blog into my site. Currently, my site is written using the Zend Framework so it's not just a case of using Wordpress and that be the end of it. I was wondering. Has someone already done what I'm thinking of doing and written a blog infrastructure with comments and so forth using ZF? Anyone got any suggestions? Thanks Steve

  • Can a .csv file be used as a data source in Visual Studio 2008 (C#)?

    - by Kevin
    I'm pretty new to C# and Visual Studio. I'm writing a small program that will read a .csv file and then write the records read to a MS SQL database table. I can manually parse the .csv file, but I was wondering if it is possible to somehow "describe" the .csv file to Visual Studio so that I can use it as a data source? I should mention that the first two lines in the .csv file contain header information and the following lines are the actual comma-delimited data.
