I'm using the system command in C++ to call some external program, and whenever I use it, a console window opens and closes after the command finishes. How can I avoid the opening of a console window? I would be happy if the solution could be platform-independent. I would also like for my program to wait until the command is finished....
Hi, We have a script that needs to function between two dates, so to test the script we need to change the UNIX system date to simulate the date conditions. PROBLEM: The problem is we have other systems running on the same server so we can't just change the UNIX system date. QUESTION: Is there a way to set the system date on the fly w...
Hi, i was wondering what the best way is to implement a tag system, like the one used in SO. I was thinking of this but i can't come up with a good scalable solution. The things i was thinking was is the basic 3 table solution. Having the tags table, the 'articles' tables, and a tag_to_articles table. Is this still the best solution to...

The system() function will launch a new process from C and a Perl script. What exactly are the differences between processes called by system() in C and from Perl scripts, in terms of representation of error codes? ...
System(); is able to call a program in PATH. How is it possible to send stdin read from e.g. a text field on a GUI to a command line program such as ftp, sftp ... with their own prompts? System() waits for a program to quit, but ftp does not without user interaction. It's also not possible to create a batch file since it's read only one ...

I've implemented an Elo rating system in a game. There is no limit for the number players. Players can join the game constantly so the number of players probably rises gradually. How the Elo values are exactly calculated isn't important because of this fact: If team A beats team B then A's Elo win equals B's Elo loss. Hence I've got a ...
My System.out.println() and System.err.println() calls aren't being printed to the console in the order I make them. public static void main(String[] args) { for (int i = 0; i < 5; i++) { System.out.println("out"); System.err.println("err"); } } This produces: out out out out out err err err err err Instead of alternating out...

Or would there be no difference, basically replacing system calls with function calls? edit: I am after lists of applications similar to memtest86 but for number crunching as examples ...

I often catch myself doing the following (in non-critical components): some_small_struct *ptr=(some_small_struct *) malloc(sizeof(some_small_struct)); ptr->some_member= ...; In words, I allocate dynamically memory for a small structure and I use it directly without checking the malloc'ed pointer. I understand there is always a chance...
We'd like to use git to maintain system configurations. Because sometimes configuration data exists outside of /etc, we've started doing something like this on our systems: # cd / # git init # git add etc # git add some/other/path # git commit -m 'initial import' And so forth. This works, up to a point. As long as your cw...
Hi everybody, I'd like to develop a tracking system using an API of course (like the famous Orange API). the idea is simple: I send a SMS (from my Web interface) to the person i want to track The person's mobile terminal (GPS like this) send me back automatically the coordinates by SMS. The sent information are displayed on the user's...
Hi all, I'm writing a Perl script that runs 4 simultaneous, identical processes with different input parameters (see background here - the rest of my question will make much more sense after reading that). I am making a system() call to a program that generates data (XFOIL, again see above link). My single-core version of this program...
apc_clear_cache [http://php.net/manual/en/function.apc-clear-cache.php] has an option to send in 'user' which will delete the apc user cache, or else if not present, the system cache. Which is better? I don't understand the difference since there's no way to explicitly store a value in one cache over the other via apc_store/apc_fetch. ...
