I am working on an RSS Reader type program and I would like it to be able to automatically import RSS feeds from the users browser bookmarks.

I'm starting with assembler under Linux. I have saved the following code as testasm.c and compiled it with: gcc testasm.c -otestasm The compiler replies: "impossible constraint in ‘asm’". #include <stdio.h> int main(void) { int foo=10,bar=15; __asm__ __volatile__ ("addl %%ebx,%%eax" : "=eax"(foo) : "eax"(foo), "ebx"(...

Hi SO Friends, I am writing code in embedded linux since last couple of years, I use make utility to build my code and I am not at all an advance user of it. But now, It is necessary to have better compilation, cross-compilation knowledge, so that I can easily port my code to newer processors. So I want to learn that which different to...
The Boost Libraries don't seem to have a device for setting a thread's priority. Would this be the best code to use on Linux or is there a better method? boost::thread myThread( MyFunction() ); struct sched_param param; param.sched_priority = 90; pthread_attr_setschedparam( myThread.native_handle(), SCHED_RR, ¶m); I don't have al...
Hi All - I'm working though the First Steps tutorial on the POCO Project site, and I've successfully built the library (Debian Linux, 2.6.26, gcc 4.3.2) under my home directory ~/Development/POCO with the shared libraries located in ~/Development/POCO/lib/Linux/x86_64/lib My problem is that any application I build that depends on t...

We believe that we are running out of video RAM in a Linux based system that we are working on. We are seeing video & graphic drivers segment faulting with allocation related errors. Are they any tools or techniques that we can use to determine how much video ram is free at any given point in time? Either an external application or so...
Hi, on my ubuntu 9.04 the /usr/include/netinet/tcp.h defines the tcp header as follows struct tcphdr { u_int16_t source; u_int16_t dest; u_int32_t seq; u_int32_t ack_seq; # if __BYTE_ORDER == __LITTLE_ENDIAN u_int16_t res1:4; u_int16_t doff:4; u_int16_t fin:1; u_int16_t syn:1; u_int16_t rst:1; ...

I was wondering how to make a program that can output to every line of the console and not just output a line to be tacked on to the bottom. How can I get control of the whole console like that so I could write console based apps? ...
I have a server application running under Cent OS. The server answers many requests per second but it repeatedly crashes after each hour or so and creates a crash dump file. The situation is really bad and I need to find out the crash cause as soon as possible. I suspect that the problem is a concurrency problem but I'm not sure. I have...
I am running a little program in python that launches a small window that needs to stay on top of all the other windows. I believe this is OS specific, how is it done in GNU-Linux with GNOME? [Update - Solution for Windows] Lovely, I think I got it working. I am using Python 2.5.4 with Pygame 1.9.1 in Eclipse on Vista 64-bit. Thus, thi...

Hi, I need to use Valgrind to detect any memory access violations made in a server application. The server creates many threads. I suspect that there is a racing condition that causes the server to crash every 1 hour or so. We used Valgrind to analyze its memory usage but the server process' speed decreased dramatically. The server's sp...
I'm writing a shell script which will store the output of a command in a variable, process the output, and later echo the results. Here's what I've got: stuff=$(diff -u pens tape) # process the output echo $stuff The problem is, the output I get from running the script is this: --- pens 2009-09-27 10:29:06.000000000 -0400 +++ tape 20...
