To me, Intel syntax is much easier to read. If I go traipsing through assembly forest concentrating only on Intel syntax, will I miss anything? Is there any reason I would want to switch to AT&T (outside of being able to read others' AT&T assembly)? My first clue is that gdb uses AT&T by default. If this matters, my focus is only on any...
I'm a linux noob wanting to migrate this piece of C# code: using System; using System.IO; using System.IO.Ports; public class LoadCell { private static string configFile = Directory.GetCurrentDirectory() + "\\LoadCell.config"; private static string errorLog = Directory.GetCurrentDirectory() + "\\LoadCell.log"; private stati...
The Perl module Proc::ProcessTable occasionally observes that the pctcpu attribute as 'inf', 'nan', or a value greater then 100. Why does it do this? And are there any guidelines on how to deal with this kind of information? We have observed this on various platforms including Linux 2.4 running on 8 logical processors. I would guess ...

Hi, I need to steal some SKBs in my NetFilter hook, and retain them for some time. Is there a limit in the kernel about how many SKBs can I use at a time? What are the consequences of having some 100,000 or even more SKBs held in my kernel module? I could avoid copying my packets two time if I can have many-many SKBs. Regards, Denes ...
Does anyone know how I can read the first two characters from a file, using a bash script. The file in question is actually an I/O driver, it has no new line characters in it, and is in effect infinitely long. ...
I need to get the stack information of my C application in certain points. I've read the documentation and searched the Net but still cannot figure out how I can do it. Can you point to a simple process explanation? Or, even better, to an example of stack unwinding. I need it for HP-UX (Itanium) and Linux. Thanks ...

I have been using this script of mine FOREVER and I have always been using "~/" to expand my home directory. I get into work today and it stopped working: #if ( $output eq "" ) { $output = "~/tmp/find_$strings[0].rslt" } # BROKEN if ( $output eq "" ) { $output = "$ENV{HOME}/tmp/find_$strings[0].rslt" } #WORKS ... open OUT_FILE,...
Hi, I'm doing IPC on Linux using boost::interprocess::shared_memory_object as per the reference (anonymous mutex example). There's a server process, which creates the shared_memory_object and writes to it, while holding an interprocess_mutex wrapped in a scoped_lock; and a client process which prints whatever the other one has written ...
I find I'm writing a lot of Makefiles that could be cleaned up with the use of n-tuple lists. But I can't find any way to do this properly (and cleanly). So far I've only been able to come up with using $(shell ...) and tr, sed, or otherwise non-Makefile standards. For example, I'd like to do this: XYZs = \ dog.c pull_tail bark \...
Here is some code sample, but the issue is that the signal handler is not called when a 'break' is sent over the serial line with 'putty'. #include <sys/ioctl.h> #include <termios.h> #include <stdio.h> #include <sys/types.h> #include <sys/stat.h> #include <fcntl.h> #include <sys/signal.h> #include <errno.h> #include <sys/types.h> #inclu...
I am running Ubuntu Linux (2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17 01:57:59 UTC 2009 i686 GNU/Linux) and it seems that the command "ulimit -t" does not work properly. I ran: ulimit -t 1; myprogram where 'myprogram' is an endless loop. I expected the program to be interrupted after 1 second, but it did not stop. I tried the same thi...

I have an interesting (at least to me) problem: I can't manage to find a way to reliably and portably get information on grandchildren processes in certain cases. I have an application, AllTray, that I am trying to get to work in certain strange cases where its subprocess spawns a child and then dies. AllTray's job is essentially to d...
