I hope to gain insight on what has already been accomplished, and what pitfalls you experienced along the way. UPDATE: From Mono Project, there are numerous applications listed such as Unity 3d, SWFDotNet, VistaDB, and even paint-mono(Paint.Net) but there are no OR/M's or IoC listed. ...
If server has php libcurl enabled, does it have all setopt options available (unless something new was added in new libcurl version and server didn't upgraded, of course) or is it possible for admins to turn off parts of functionality? I'm especially thinking about CURLOPT_HTTPHEADER - can i assume that if i'll be running my script on s...
How can I check a problem with mail being sent on my server? I run a simple test: if(mail($to, $subject, $message)) { echo 'Mail Sent'; } which the test outputs the text. But no mail ever arrives. How can I go about tracking down the issue? Thanks Rich ...

Is there any reason (other than syntactic ones) that you'd want to use FILE *fdopen(int fd, const char *mode); or FILE *fopen(const char *path, const char *mode); instead of int open(const char *pathname, int flags, mode_t mode); when using C in a Linux environment? ...
I have had difficulty figuring out how to use F# on Linux - I would really appreciate help. ...
I am missing something when it comes to understanding the need for highmem to address more than 1GB of RAM. Could someone point out where I go wrong? Thanks! What I know: 1 GB of a processes' virtual memory (high memory region) is reserved for kernel operations. The user space can use the remaining 3 GB. This is the 3/1 split. The...
When I do a "dbus_connection_close", do I need to flush the message queue? In other words, do I need to continue with "dbus_connection_read_write_dispatch" until I receive the "disconnected" indication or is it safe to stop dispatching? Updated: I need to close the connection to DBus in a clean manner. From reading the documentation, a...
I'm taking a course in operating systems and we work in Linux (Red hat 8.0). I'm trying to implement a file open,close tracker that will save for every process a history of files it opens and closes. I expected sys_open,close to also accept the process id and that I could use that to access the history of the process that initiated the c...
Is there a way to generate Excel spreadsheets with Perl on Linux so that I can open the spreadsheet on Windows and it creates native Excel graphics? I know that there are libs to draw graphics but all libs I know simply insert a picture to the Excel which looks weird when I open the spreadsheet on Windows. So I wondering is there a way t...
I'm in the process of moving from XP to Linux. (I'm new to Linux) I have succesfully installed CLIPs on Ubuntu, using the SPM. I would however, like to build CLIPS from the sources - since I will be extending its current functionality. I have downloaded the CLIPS sources (v6.2.4) from http://sourceforge.net/projects/clipsrules/files/C...
Hi, I have been trying to make an init script using start-stop-daemon. I am stuck on the arguments to the daemon. I want to keep these in a variable at the top of the script but I can't get the quotations to filter down correctly. I'll use ls here so we don't have to look at binaries and arguments that most people wont know or care abou...
I have a web dev. client using a shared host that doesn't allow shell access, and thus no access to SVN, Git, etc. I've tried to convince him to move to one of the many cheap options that allow it, but he won't do it. If I use version control on my staging server, are there any tools that will allow me to replicate the changes to product...
This just started happening three weeks or so ago. The content of my website hasn't changed, it's just a phpBB forum using MySQL as a backend. Nothing has changed in well over a year but recently, every two days or so, the server just shuts down and cannot be accessed at all, I have to notify my service provider to physically restart...
I've found lots of libraries to help with parsing command-line arguments, but none of them seem to deal with handling filenames. If I receive something like "../foo" on the command line, how do I figure out the full path to the file? ...
I'm trying to add a new syscall in Red Hat 8.0 and I'm confused about some aspect of the mechanism. I've been following this guide: http://www.linuxjournal.com/article/3326 which details the steps of updating the syscall table in entry.S and unistd.h. However, I can't seem to figure out how the compiler actually finds where the syscall ...
While I have played with parts of Qt in the past I am thinking of putting some real effort into learning it but also wondering what the potential monetary payback might be down the road. So I have some general questions about Qt's future. What is Qt's place in the job market? Are there many, or do you sense a growing number of install...
I'm interested in learning to write C programs which use threads. I picked up the following demo off the web from https://computing.llnl.gov/tutorials/pthreads/ #include <pthread.h> #include <stdio.h> #define NUM_THREADS 5 void *PrintHello(void *threadid) { long tid; tid = (long)threadid; printf("Hello World! It's me, thre...
Hi, I want to know if there is an efficient solution to monitor a process resource consumption (cpu, memory, network bandwidth) in Linux. I want to write a daemon in C++ that does this monitoring for some given PIDs. From what I know, the classic solution is to periodically read the information from /proc, but this doesn't seem the most...
other than getdomainname() is there any way to get the domain name on Linux without having to open and parse files in /etc? Code is appreciated. Thanks ...
