I know that Apache creates as many instances of a CGI program as required but I have no idea how those instances write to the same file in an orderly manner.For example, a CGI program called by Apache inserts additional data in a file, is that file made automatically unavailable to the other instances (children) of this CGI program while it is inserting the data? Or should the CGI program do that?
View 2 RepliesI have about 200k data entries in xml file. I wrote php script (using php-xml) to read xml file and insert into mysql. At first it went really quickly inserting, then after a while after inserting 100k entries, it slowed right down, just like it would not even doing anything. I have CentOs with 512M on VirtualBox running as server.
View 3 Replies View RelatedI'm writing a C program, and using Autotools. I have a large text file that I need to include verbatim, as data for my program.I used to have a hacked-together Perl script that would take a file like this: Code: A Rabbi, a Priest, and a Minister walked into a bar.The bartender said, "What is this, a joke?" I found this site that contains instructions for doing exactly what I want, but that technique requires GNU's ld, and the whole point of using Autotools in the first place is to make my project platform- and compiler-independent.I should point out that, according to the Autotools help, I can do this with a script called either "txtc.sh" or "txtc.sh.in". Unfortunately, Google can't find such a script, and it's not in any package that I can find.

View 2 Replies View RelatedI am trying to store the data in my program in a map of priority_queues an I am having a bit of trouble doing it. basically I am storing activities (ie watching tv, eating dinner, playing ping-pong, etc) and I want these event grouped by the day that they happened on.
my first thought was to use a multimap where the key is the date, and the value is the activity, however I would like to keep the activities in a specific order. I have tried to find the proper syntax for this but have frustratingly come up empty. Even google provided little assistance.
I am looking for a program to help me store, organise and retrieve information. The aim would be to keep notes from literature, concepts and ideas which i come across during my studies. It's always a hassle to retrieve this information when i have to write a paper for instance. So in fact what i need is a sort of wikipedia-like program where information is searchable and where perhaps hyperlinks could lead me from one word/note to another.
View 2 Replies View RelatedWhat I want to do is force my DVD burner to use full writing power on the entire surface of a DVD. This should be able to invisibly damage the contained data, and should work on CDs, DVDs and BRDs too (in theory). I don't want to write data over it, so it's not a matter of having a RW disc or a R one. The result I want to obtain is simply an unreadable disc that does not look damaged. Do you know if there's a program able to ignore a disc being already full and perform this task?
View 2 Replies View RelatedI'm running a program called Synergy+ to let my keyboard and mouse control multiple computers. One of Synergy+'s features is that clipboard (copy-paste) data is able to be shared, as in copy on one machine, paste onto another. I would like this functionality removed but Synergy+ has no way to disable it. I'm looking for any ideas to block clipboard data from being transferred. Is there a way to block a program from accessing the machine's clipboard data?

View 3 Replies View RelatedI have connected a device to my linux system with a serial cable (rs232). The settings are: port /dev/ttyS0, baud rate=38400, data bits=8, stop bits=1, no parity, no hardware or software handshaking. I wrote a linux program that sends 1 byte to the device, but the device doesn't receive it. I know the serial ports are working because when I use the CuteCOM application to send data, the device DOES receive it, so obviously it is a problem with my code..
Code:
#include <stdio.h>
#include <stdlib.h>
#include <math.h>

I have my system connected to a sky wifi box (LAN connection) for my broadband, I also have about 4 tenants connected too, via wireless.
I was wondering if there were a program that i could run on my system that could monitor, or that i could use that would tell me how much data each person is using/downloading and what websites they were viewing etc..
i wanted to capture the stdout and stdin of a child process within a parent so that any output of child is sent to the parent and any input taken from the parent. code is simple enough and i have followed all code guidlines on the internet (some guidlines do differ also) my select call either hangs if i do not give a tmeout and with a timeout it returns 0 descriptors to be written to or read from:
below is the simple code for parent:
int main(void)
{
int outfd[2];
int infd[2];
[code].....
why select hangs without a timeout ... why can it not detect that the pipe is write ready i.e parent can write to it ... if it does not detect tha read pipe as having data...
I wrote a serial port communication program to access a equipment.
int main(void)
{
int fd = 0;
int nread = 0,i = 0,nwrite = 0, tmpread = 0, m = 0, n = 0 ;
[code]....
I dont want to wipe the whole drive, and i don't want to delete only particular files. I want to completely destroy all data in free space.I've found some articles about secure-delete package for linux that would allow erasing freespace with the command 'sfill,' but I can't find it in the repositories nor through google. This would be ideal but it seems maybe it's debian only.

Is it some kind of identification of the disk?

I need to either locate a script that is similar to what I am needing or figure out a better way of doing what I need. I have mutiple shops with AIX unix servers, using ksh with virtual terminals that connect. since these are on an internal network we have them connecting to the server as either usr01, usr02, etc. what I need to do is add 15 user's ranging from usr01-usr15 into /etc/passwd each usr is identical in such that each line contains
Code:
usr01::0:0::/usr/tops:/bin/ksh
only difference is the usr# changes. I wrote a script where I was just adding these all to the /etc/passwd but now I have been tasked with adding them to these shops but with out any duplicates. is there any way to have a script check the file to see if the usr# exists and if so proceed to the next number and then input the usr#::0:0::/usr/tops:/bin/ksh into the file?

View 8 Replies View RelatedI have Ubuntu 8.04, and Rythmbox 0.11 I am using for my home music source. I have been building a music library on my hard drive by inserting CD's, then using the "Copy to library" function. This works fine, but when I insert the CD, Rythmbox stops playing from the play list and switches to playing the CD. How do I stop this?
I can (and do) stop the player, manually go back to the play list, restart the player, then I can transfer the music from the CD to the hard drive. I'd just as soon not have it auto play. Or, alternately, is there another jukebox like player with more features that can handle the above? I find the shuffling isn't what I like, it seems to play some songs a lot more then others but I can live with that.
