  • git merge specifies wrong author

    - by dhblah
    I have a problem with latest version of git i compiled under cygwin. At first, it displays editor to enter merge message. Previously, it went sailent. And then commit author seems to be different from normal commit. When I do manual commit, author is User Name <[email protected]>, but when I do merge author name is Domain\username <[email protected]> Is there a way to make merge to specify the same auther as for manual commit? What's happening?

  • PHP debugging or performance Hook

    - by Joshua
    In an interpreted language like PHP it is possible in theory to set up some sort of callback function that would be run indiscriminately after every line of code. I am wondering if such a thing exists in PHP or if such a thing could be accomplished in any way? Such a feature could be useful for diagnostics or performance tests. Does anyone know of such a mechanism in PHP?

  • dreferencing 2 d array

    - by ashish-sangwan
    Please look at this peice of code :- #include<stdio.h> int main() { int arr[2][2]={1,2,3,4}; printf("%d %u %u",**arr,*arr,arr); return 0; } When i compiled and executed this program i got same value for arr and *arr which is the starting address of the 2 d array. For example:- 1 3214506 3214506 My question is why does dereferencing arr ( *arr ) does not print the value stored at the address contained in arr ?

  • Apple Mac Software Development

    - by MattMorgs
    I'm planning on developing an Apple Mac application which will collect hardware information from the host Mac and also installed software info. The hardware and software info will be collected in an encrypted XML file and then posted back to a website. The application should run as a "service" or background process on the Mac and can be configured to collect the data on a frequent basis defined by another encrypted XML config file. I've done plenty of Windows based software development but never on the Mac. Can anybody point me in the direction of any useful info on how to develop on the Mac, collect hardware and software info, export to an XML file, file encryption and packaging a compiled app to run as a service? Is either Objective C, Cocoa or Ruby a possible option? Many thanks for your help in advance!

  • How to resize an image smoothly (with resampling) using Windows API calls?

    - by Clay Nichols
    I need to resize images and resample them so they don't end up all jagged (I think that's called aliasing). I found some code (sorry, lost the link) that does this in pure VB6 code but it's a bit slow (2-5 seconds) and I'm displaying pictures in real time so I need something faster. I seem to recall seeing some examples of doing this with the GDI+ library. An example in VB6 would be ideal, but I can probably work with a simple example with Windows API calls in another language.

  • ShowDialog and Hide form, when from is called from other object in VS2010

    - by Piotr Dabrowski
    Hallo, I have a modal Form, used for searching information in DB. This Form is used by a COM object, that waits for search result. Initialization of the form take a lot of time (because of building connection to DB). So, I initialize the Form (without showing it), and keep Form-object alive, as long as COM-object work. In this way I keep the state of the Form: public void Search() this.ShowDialog(); string result = this.ResultOfSearch; this.Hide() return result; And it doesn't work anymore on VS2010 (compiled for Framework 2.0). I search for alternative way to make a modal form (or a method to protect a form against Destroy() at the end of ShowDialog). Any ideas?

  • Which do I select - Windows Azure or Amazon EC2 - for hosting unmanaged C++ code?

    - by sharptooth
    We have a server solution written entirely in unmanaged Visual C++. It contains complicated methods for really heavy data processing. The whole thing contains millions lines of code, so rewritning it all in some other language is not an option. We could write some extra code or make isolated changes, but rewriting everything is out of the question. Now we'd like to put it on a cloud. Which platform do we choose - Amazon EC2 or Windows Azure - and why?

  • Which IDE / code editor was the first to introduce a code completion feature?

    - by Uri
    I am trying to identify the point in time where code completion (autocomplete/intellisense/whatever) was first introduced in IDEs and would appreciate any pointers. By code completion here I mean a feature within the editor that offers methods or suggestions based on the code that was already typed, and I am interested in programming language related completions (not word processor style completion).

  • Strange profiler behavior: same functions, different performances

    - by arthurprs
    I was learning to use gprof and then i got weird results for this code: int one(int a, int b) { return a / (b + 1); } int two(int a, int b) { return a / (b + 1); } int main() { for (int i = 1; i < 30000000; i++) { two(i, i * 2); one(i, i * 2); } return 0; } and this is the profiler output % cumulative self self total time seconds seconds calls ns/call ns/call name 48.39 0.90 0.90 29999999 30.00 30.00 one(int, int) 40.86 1.66 0.76 29999999 25.33 25.33 two(int, int) 10.75 1.86 0.20 main If i call one then two the result is the inverse, two takes more time than one both are the same functions, but the first calls always take less time then the second Why is that? Note: The assembly code is exactly the same and code is being compiled with no optimizations

  • How could my code compliled correctly without necessary headers?

    - by ZhengZhiren
    I use the functions fork(),exec()... But how can this program compiled without including some extra headers(like sys/types.h, sys/wait.h). I use ubuntu 10.04 with gcc version 4.4.3 #include <stdio.h> #include <stdlib.h> int main() { pid_t pid; printf("before fork\n"); pid = fork(); if(pid == 0) { /*child*/ if(execvp("./cpuid", NULL)) { printf("error\n"); exit(0); } } else { if(wait(NULL) != -1) { printf("ok\n"); } } return 0; }

  • python: list manipulation

    - by Jason S
    I have a list L of objects (for what it's worth this is in scons). I would like to create two lists L1 and L2 where L1 is L with an item I1 appended, and L2 is L with an item I2 appended. I would use append but that modifies the original list. How can I do this in Python? (sorry for the beginner question, I don't use the language much, just for scons)

    - by osgx
    Hello Where can I find examples of code, written in "Unified Parallel C"? I also interested in normative documents about this language (standards, reference manuals, online-accessible books and courses). What extensions were added to C to get UPC? Is this dialect alive or dead?

  • Can .NET AppDomains do this?

    - by Eloff
    I've spent hours reading up about AppDomains, but I'm not sure they work quite like I'm hoping. If I have two classes, Foo in AppDomain #1, Bar in AppDomain #2: App Domain #1 is the application. App Domain #2 is something like a plugin, and can be loaded and unloaded dynamically. AppDomain #2 wants to create Foo and use it. Foo uses lots of classes in AppDomain #1 internally. I don't want AppDomain #2 using object foo with reflection, I want it to use Foo foo, with all the static typing and compiled speed that goes with it. Can this be done considering that AppDomain #1, containing Foo, is never unloaded? If so, does any remoting take place here when using Foo? When I unload AppDomain #2, the type Foo is destroyed?

  • Where did the name `atoi` come from?

    - by Earlz
    Ok I've been curious about this for a while. In the C language where did they come up with the name atoi for converting a string to an integer? The only thing I can think of is Array To Integer for an acronym but that doesn't really make sense.

  • Why is the Java VM so popular?

    - by sdudo
    There are more and more programming languages (Scala, Clojure,...) coming out that are made for the Java VM and are therefore compatible with the Java Byte-Code. I'm beginning to ask myself: Why the Java VM? What makes it so powerful or popular that there are new programming languages, which seem gaining popularity too, created for it? Why don't they write a new VM for a new language?

  • a good resource or book for architecting object-oriented software

    - by Ygam
    I have looked at a couple of books and all I have looked at were just discussing the technicalities of OOP. By technicalities I mean, here's a concept, here's some code, now get working. I have yet to see a book that discusses the architectural process, what are the ways of doing this, why doing this is bad, how to actually incorporate design patterns in a real-world project, etc. Can you recommend a good resource or book? I am mainly programming with PHP but a language-agnostic book/resource would do :)

  • Common files in output directories in a C# program

    - by Net Citizen
    My VS2008 solution has the following setup. Program1 Program2 Common.dll (used and referenced by both Program1 and Program2) In debug mode I like to set my output directory to Program Files\Productname, because some code will get the exe path for various reasons. My problem is that Program1 when compiled, will give an error that it could not copy Common.dll if Program2 is started. And vise versa. The annoyance here is that I don't even make changes to Common.dll that often, but 100% of the time it will try to copy it, not only when there are changes. I end up having to close all programs, and then build and then start them. So my question is, how can I only have VS2008 copy the Common.dll if there are changes inside the Common.dll project?
