• git-svn clone checkouts wrong repo?

  - by hyperboreean

  So I am trying to switch to git, by using git-svn. I am having a svn repo called myrepo from which I want to clone just the project called myproject. The thing is that by running the following command: git svn clone path-to-repo/myrepo/myproject --stdlayout --prefix=svn myproject the whole repo myrepo is cloned rather than just myproject. I tried using -T, -t, -b as well to let git know about the layout of the project, but without any success. I always get the following output: Using higher level of URL: path-to-repo/myrepo/myproject => path-to-repo/myrepo and tries to clone that one. Am I doing something wrong? It might be that the svn repo layout could be broken or git incompatible ?

• for loop vs while loop

  - by Atul

  We can use for loop and while loop for same purpose. in what means they effect our code if I use for instead of while? same question arises between if-else and switch-case? how to decide what to use? for example which one you would prefer? This code: int main() { int n; cin>>n; for(int i=0;i<n;i++) { do_something(); } return 0; } Or this code: int main() { int n,i=0; cin>>n; while(i<n) { do_something(); i++; } return 0; } if using for or while loop does not effect the code by any means then may I know What was the need to make 2 solution for same problem?

• The glutKeyboardFunc does not react to key presses immediately

  - by Nibirue

  I have a function glutKeyboardFunc(keyboard), where keyboard has: void keyboard(unsigned char key, int x, int y){ float alpha = 1.0; switch(key){ case 'c': glClearColor(1,0,0,alpha); printf("success"); break; } } This is a summary of the function; it works properly, but only once some other action has occurred. For instance, the printf statement reports success immediately on keystroke 'c', but the background color does not become active until I click somewhere else on the canvas. I want all keystrokes to have an immediate effect.

• How to create a project from existing source in Eclipse and then find it?

  - by Roman

  I have created several .class files. All of them are located in one directory. I used a text editor to write these class files. Now I want to switch to Eclipse. In Eclipse I click File-New-Java Project. Then I select "Create project from existing source". After that I select the directory where all my .class files and click OK. As a result, nothing visible happens. But when I try to do the same, Eclipse tells me that that this project already exist. Where does it exist and how can I access it? By the way, in my "workspace" file nothing new appeared. Is it OK? I though my new Java Project will be there.

• .BAT Switches Parsing

  - by giiYanJ

  Erm.. I'm working with a switches parsing in BAT files, which goes like this: <commands> -a -b -x -y -z -u abc ...... The user may input a lot of switch, or none. So I used looped shift to make parsing infinite switches possible: :loop IF "%1"=="-a" ... SHIFT GOTO loop But when the script ends, I always get cmd executing the switches and showing up error like '-n' is not recognized as an internal... So, someone got any idea? Thanks a lot... P/S: Make solution sticks with BAT script if possible as using other language may cause dependencies problem as this script is aimed on ANY computer with Windows. Finally, thanks again =) EDIT: Tried shf301 suggestion, i found out that I used DEL %0 to delete itself but it seems the %0 is shifted into the arguments because of the SHIFT command.

• Toggle alternative

  - by Nutmeg

  In a contactform I am using both the jQuery validation plug-in 1.3 and the following (slide) script: $(document).ready(function() { // Expand Panel $("#open").click(function(){ $("div#contact").slideDown("slow"); }); // Collapse Panel $("#close").click(function(){ $("div#contact").slideUp("bounce"); }); // Switch buttons from "Log In | Register" to "Close Panel" on click $("#toggle a").click(function () { $("#toggle a").toggle(); }); }); Problem is that the validation plug-in 1.3 uses the following segment: addWrapper:function(toToggle){if(this.settings.wrapper)toToggle.push(toToggle.parents(this.settings.wrapper));return toToggle;}, which conflicts with the slide code. What's the smartest way to go about this? Using the toggleClass instead? Thanks for your help!

• iDevice for Dummies: Can a device be assigned multiple provisions (Personal/Enterprise)?

  - by Alex

  Hi guys, Is it possible to assign multiple provisions to an iDevice? To be honest, I'm not sure if I'm using the correct terminology, but basically, I'm developing an iPad app for a company and I've only been testing it in the simulator because I don't have a registration to the developer program and they haven't setup their enterprise registration yet either. And I'm sure you all know how limited the simulator is... I don't really care about the $99 it costs to join, but what I'm worried about is having my iDevices locked permanently to my personal registration and unable to switch back and forth to the enterprise registration. I'd appreciate it if someone can explain to me how the registrations work. And keep in mind, I'm a dummy. :) Thanks in advance!

• Django: HTTPS for just login page?

  - by Mark

  I just added this SSL middleware to my site http://www.djangosnippets.org/snippets/85/ which I used to secure only my login page so that passwords aren't sent in clear-text. Of course, when the user navigates away from that page he's suddenly logged out. I understand why this happens, but is there a way to pass the cookie over to HTTP so that users can stay logged in? If not, is there an easy way I can use HTTPS for the login page (and maybe the registration page), and then have it stay on HTTPS if the user is logged in, but switch back to HTTP if the user doesn't log in? There are a lot of pages that are visible to both logged in users and not, so I can't just designate certain pages as HTTP or HTTPS.

• How to control the state of the buttons to be in present based on an event happened in a Silverlight app?

  - by vladc77

  I am trying to avoid building two buttons when I really need one. In my Silverlight app scenarios, I have few grids with a different content and buttons that control the visibility of these grids. I need to be able to show a different visual for a button when its content grid is visible. I can control states such as MouseOver and Pressed and more with visual state manage. However, I am not sure how to achieve this functionality with. I also can place an image on top of the button and switch the visibility of both but it is not perfect for what I need. I am wondering if there is any way to achieve this behavior. Any ideas are highly appreciated!

• Interrupt a thread in DatagramSocket.receive

  - by SEK

  I'm building an application that listens on both TCP and UDP, and I've run into some trouble with my shutdown mechanism. When I call Thread.interrupt() on each of the listening threads, the TCP thread is interrupted from listening, whereas the UDP listener isn't. To be specific, the TCP thread uses Socket.accept(), which simply returns (without actually connecting). Whereas the UDP thread uses DatagramSocket.receive, and doesn't exit that method. Is this an issue in my JRE, my OS, or should I just switch to (Datagram)Socket.close()?

• Arduino TimeSerial

  - by user541597

  I am working with the TimeSerial sketch (an example in the Arduino Time library). Everything works fine, and I can get it to output the time continuously. I am trying to set a switch which will read in a serial.read(). For example, I send 1 through the serial monitor, my sketch reads the one and runs a function I've created called resetfunc() which all it does is end serial and go back up to setup. It then asks me to enter the T and time stamp but doesn't wait and just keeps printing time. Why is it still doing this? When I haven't sent it the T and timestamp through serial yet?

• [C] How I change a variable of a type to another one?

  - by drigoSkalWalker

  I want to do it: int main () { bla bla bla void *onetype; switch (USER_INPUT_TYPE) { CASE CONVERT_TO_CHAR: convert onetype VOID TO CHAR HOW??? CASE CONVERT_TO_INT: convert onetype VOID TO INT HOW??? LOT OF CASES... } } Yes, I know type casting, but type casting is a 'temporary' change... So...Is there any way to accomplish it in C? EDIT : Stop stop stop! Please, see, what are you doing is type casting, I KNOW THIS, you are creating another variable of the desirable type like int i = (int) onetype, I don't want this, I want something else like onetype = (int) onetype, without recreate them, without allocate another variable. Thanks a lot guys!

• Do you know any build systems with decent support for parallelization?

  - by dahpgjgamgan

  Hi, I am looking for a build system (working on ms windows) that has good support for parallelization of tasks/targets (or whatever you call them). To be more specific - during build (that is initiated on MS Windows machine) I need to copy source files to a number of different machines (which are not necessarily running Windows) and start a remote job on each of them - and I really like to do that on all machines at once. Does anyone know a build system that's capable of executing such a task in parallel. From what I googled, the options currently available are: -j switch in make - but i don't know if nmake supports this -some custom nAnt tasks -msbuild has some form of support for parallelization - seems similiar to make (meaning you don't specify what to do in parallel, just specify that it would be nice to build things that way) -fake (f# make) is written in functional programming language which are known to have good parallelization support - but I'm not very skillful in functional programming area. Any other solutions I could explore?

• I have an Xcode static library project, how do I add a test target to it so I can run it there? (Ins

  - by zekel

  I want to be able to test library code in the library target so I don't have to switch over to a separate project to run it. I see how to add a target, but I'm not sure how to set it up to run like the "Command Line Tool" project template does. I tried adding a new "Shell Tool" target, but I don't know how to make it run like one. What build settings do I have to add to that target? What files (main.m?) do I need to start it up?

• modifying constants in objective c during run time

  - by moshikafya

  I am trying to solve the following problem. I have the following constants in my header file: #define PREFS_MY_CONSTANT_1 @"bla1" #define PREFS_MY_CONSTANT_2 @"bla2" #define PREFS_MY_CONSTANT_3 @"bla3" ... In one of my functions, I'd like to print to the UIbutton one of those strings based on user input, so say the user inputs '1', i would show bla1. Instead of creating a huge switch (i have 100 of those), I am looking for a way to combine the constant with the variable holding the user input, so something like that ideally: NSInteger input; [button setTitle:PREFS_MY_CONSTANT_{$input} forState: UIControlStateNormal]; Is something like that possible? what would be the best way to solve this?

• c++: truth assignment warning with arguments?

  - by John

  I use the following to work with arguments in my programs, but it seems to just hand me a warning (just a warning): "warning: suggest parentheses around assignment used as truth value" The beginning of the code is as follows: enum{OPT_DISP_H = 0x2, OPT_DISP_W = 0x1}; int main(int argc, char *argv[]) { int opt = 0x00; char c; while((++argv)[0] && argv[0][0]=='-'){ while(c =* ++argv[0]) switch(c){ case 'h': opt |= OPT_DISP_H; break; //etc.. The while(c =* ++argv[0]) part being where the warning persists. The code works fine, but what does this warning mean opposed to what is used? I think the code is c = *++argv[0], using the pointer. So why does the single = work and what is really recommended to be used?

• What is the business case for a dependency injection (DI) framework?

  - by kalkie

  At my company we want to start using a dependency injection (DI) framework for managing our dependencies. I have some difficulty with explaining the business value of such a framework. Currently I have come up with these reasons. Less source code, delete all the builder patterns in the code. Increase in flexibility. Easier to switch dependencies. Better separation of concern. The framework is responsible for creating instances instead of our code. Has anybody else had to persuade management? How did you do that? What reasons did you use?

• Deployment process

  We are having a massive system having around 15 servers hosting .Net WCF services, mvc application etc. When we do a deployment (out of office hours) we have to uninstall and install everything on the live servers. This takes lot of time and if something goes wrong we have to rollback everything. can you please suggest something different to this? like Deply into a other environment (whenever you like) and switch the URL to point to new servers [This comes with the overhead of cost of maintaining 2 copies of production (active and passive)] any other ideas please.

• Database design to hold multiple iteration measurements

  - by Valder

  Hi All. I am new to sqlite and SQL in general. I am keen to switch from flat-files to sqlite for holding some measurement information. I need a tip on how to better layout the database, since I have zero experience with this. I have a ~10000 unique statistic counters that are collected before and after each test iteration. Max number of iterations are 10, though it could be less. I was thinking the following: CREATE TABLE stat_names(stat_id, stat_name); CREATE TABLE stats_per_iteration(stat_id, before_iter_1, after_iter_1, before_iter_2, after_iter_2, ...); stat_names table would hold mapping of a full counter to a uniq stat_id. stats_per_iteration table would hold mesurement data 1 + 10 * 2 columns. stat_names.stat_id = stats_per_iteration.stat_id OR maybe I should have a separate table for each iteration? Which would results in 1 + 10 tables in database. Thanks!
