I'm writing a plugin to highlight text strings automatically as you visit a web site. It's like the highlight search results but automatic and for many words; it could be used for people with allergies to make words really stand out, for example, when they browse a food site. But I have problem. When I try to close an empty, fresh FF wi...

after doing $ cat /dev/input/by-path/pci-0000:00:02.0-usb-0:2:1.0-event-kbd > ~/test_kbd as root, I got a bunch of binary codes (which was expected). Now, I wanted to know how can I interpret this binary code to figure out what key has been pressed? What format is the output in? and is there a reference I could look at that would t...
I have a Debian (lenny) server with 9 sata disks. One disk is connected to the motherboard's sata controller. The others are connected to two PCI sata controllers (four disks each). The disk connected to the motherboard is the boot disk. Before this has worked fine and the boot disk has always been /dev/sda. But after upgrading the kern...
I have some code that uses some shared libraries (c code on gcc). When compiling I have to explicitly define the include and library directories using -I and -L, since they aren't in the standard places. When I try to run the code, I get the following error: ./sync_test ./sync_test: error while loading shared libraries: libsync.so: can...

Hi Everyone, I am running some code that I have written in C which calls the md5 hashing functionality from a hashing library that someone else wrote (md5.c & md5.h). The odd behavior I have been seeing is: hashing working perfectly = I hash a string, and it comes out to the exact hash that I have verified it to be with multiple other...

I think of implementing a file search program using indexing in linux... I know that there are several other file search programs like beagled. but I am doing this for study purpose... I am struck with how to do indexing.. I have the following idea that I took from maemo-mapper application.. for example if u have file named "suresh" its ...
I have to import a large mysql dump (up to 10G). However the sql dump already predefined with a database structure with index definition. I want to speed up the db insert by removing the index and table definition. That means I have to remove/edit the first few lines of a 10G text file. What is the most efficient way to do this on li...
Hi! I have a question: Is there some way to the SPID in linux 2.6 from a C++ application? When I do a "ps -amT" I can see the threads in the process: [email protected]:~# ps -amT PID SPID TTY TIME CMD 1120 - pts/1 00:00:20 sncmdd - 1120 - 00:00:00 - - 1125 - 00:00:00 - - 1126 - 00...
Ok it might sounds dumb, but I couldn't figure out a way to pass int/char into this system call here is how I would like it to work system ("cal %d %d", month, year); I expect this will give me the following command on terminal "cal 3 2009" and the terminal will show me the calendar of March 2009. But the compiler is complaining ...

I would like a particular set of Python subprocesses to be as low-impact as possible. I'm already using nice to help limit CPU consumption. But ideally I/O would be limited as well. (If skeptical, please humor me and assume there is value in doing this; it doesn't matter how long they take to run, there can be a lot of them, and there...
Ok I need to make this program to display "cal" 3 month(one month before and one month after) side by side, rather than just one single month it displays in any Linux/UNIX. I got it working to display 3 calendar by using "system(customCommand)" three times; but then it's not side by side. I got some hint to use the following system cal...
I'm wondering what is the recommended audio library to use? I'm attempting to make a small program that will aid in tuning instruments. (Piano, Guitar, etc.). I've read about ALSA & Marsyas audio libraries. I'm thinking the idea is to sample data from microphone, do analysis on chunks of 5-10ms (from what I've read). Then perform a FF...
I'm quite comfortable with C for numerical computation, but not for graphical programming. I have a Nx by Ny by 3 RGB matrix in a command-line program for linux (gcc, ubuntu) and I want to pop up a window with it as an image. What's the easiest way to do this? It has to be relatively quick because I'll be updating the image frequently....
I have a 2GB text file on my linux box that I'm trying to import into my database.
