I've recently been given a MS Access .mdb database file and asked to make it usable in a Linux system. What I'm looking for is a way to convert the Access database to an open-source database such as MySQL or PostGres. I don't have MS Office, and it's a one-time project for a volunteer organization so I don't want to spend money if it...
I am writing a server program in C wherein every time a client connects, I create a new pthread to handle the client's requests. When all of the threads exit, however, then my program exits, as though a call to exit() has been made. This is a problem - how can I overcome it? Lets say the server is running, and 2 clients connect. Once t...

We have a business application that basically runs on an os-independent stack (tomcat+java+mysql) but we have always run it redhat or centos. There is a customer that is insisting to run it on opensolaris for his own reasons (an expensive everything-is-included support agreement with Sun). How painful can such a migration be? We have ...
My logging code uses the return value of backtrace() to determine the current stack depth (for pretty printing purposes), but I can see from profiling that this is a pretty expensive call. I don't suppose there's a cheaper way of doing this? Note that I don't care about the frame addresses, just how many of them there are. edit: These...

I am writing a Linux kernel module on Fedora core 6 and I am wondering if anyone could tell me how to add the assembly code shown below to my program. The assembly code was written for Windows and I have no idea how to convert to Linux kernel program. #ifdef _MSC_VER unsigned char lookKbits(char k) { _asm { mov dl, k ...
Under Linux, how can I tell what specific process owns / is using a given address in physical memory? I understand that this may require writing a kernel module to access some kernel data structure and return the results to a user - I need to know how it can be done, regardless of how complicated it is. ...
I am trying to locate a set of source code that would allow me to open and read the contents of an Excel file on Linux from within a C program. I dont really want to link it to OpenOffice SDK if I can find something that just does these two things. carl ...
I have a program that's running in two different modes. I want to compare the two modes with regard to runtime and memory requirements. Determining runtime is easy with using time. In fact, in this case it's really easy because the program reports both the CPU time and the wallclock time at the end of the test. However, determining m...
1st of all: I'm not programmer, neither Linux guru, just have to work with Linux, Oracle, shell scripts. My current task is to monitor a table in Oracle (tool: sqlplus), and if it contains a certain row, then watch a linux directory for a growing tmp file, and log its attributes (e.g. ls -l), in every 5 second. The most important part...
Hi Is it possible for me to change or assign my server a new IP address every time it needs to make a http request with commands such as wget? Thanks all Update The reason for this is exactly what the Tor project is trying to achieve. I do not want to leave a trace of what requests my server makes and I thought constantly changing my...

Is there any reason in particular why it's recommended to run memcached on a Linux server? Is it really that bad an idea to run it on a Windows Server box? What about an OS X Server box? The biggest reason that I read is about TCO. In other words, for each windows box that we run memcached on, we have to buy a copy of Windows Server ...
