Can anyone point me to a good tutorial on creating a bootable Linux CD from scratch? I need help with a fairly specialized problem: my firm sells an expansion card that requires custom firmware. Currently we use an extremely old live CD image of RH7.2 that we update with current firmware. Manufacturing puts the cards in a machine, boots...
I am interested in moving a number of my projects from Visual Studio and Access/Office Basic with a SQL back-end to the Linux world. Are there any utilities available to move code over to a similar platform on Linux? I apologize in advance for my naiveté, it's been at least 18 years since I last worked in a Unix environment... Thanks ...
When running my application I sometimes get an error about "too many files open". Running "ulimit -a" reports that the limit is 1024. How do I increase the limit above 1024? Edit "ulimit -n 2048" results in a permission error. ...
Some code that rounds up the division to demonstrate (C-syntax): #define SINT64 long long int #define SINT32 long int SINT64 divRound(SINT64 dividend, SINT64 divisor) { SINT32 quotient1 = dividend / divisor; SINT32 modResult = dividend % divisor; SINT32 multResult = modResult * 2; SINT32 quotient2 = multResult / divisor; SI...
I want to be able to get an estimate of how much code & static data is used by my C++ program? Is there a way to find this out by looking at the executable or object files? Or perhaps something I can do at runtime? Will objdump & readelf help? ...
I have a large GUI project that I'd like to port to Linux. What is the best framework to use for GUI programming in Linux? Should KDE / Gnome frameworks be used? Or can I use something more generic other than X? I feel like if I chose one of Gnome or KDE, I'm closing the market out for a chunk of the Linux market who have chosen one ov...
What's the current status of Mono's Platform Invoke implementation on Linux? And on Solaris? ...
How can I improve the look and feel of my Linux desktop to suit my programming needs? I found Compiz and it makes switching between my workspaces (which is something I do all the time to make the most of my 13.3" screen laptop) easy and look great - so what else don't I know about that make my programming environment more productive/ple...
Heyall... I want to build a lightweight linux configuration to use for development. The first idea is to use it inside a Virtual Machine under Windows, or old Laptops with 1Gb RAM top. Maybe even a distributable environment for developers. So the whole idea is to use a LAMP server, Java Application Server (Tomcat or Jetty) and X Window...
I have a set of Berkeley DB files on my Linux file system that I'd like to examine. What useful tools exist for getting a quick overview of the contents? I can write Perl scripts that use BDB modules for examining them, but I'm looking for some CLI utility to be able to take a look inside without having to start writing scripts. ...
I'm looking for some software that allows me to control a server based application, that is, there are bunch of interdependent processes that I'd like to be able to start up, shut down and monitor in a controller manner. I've come across programs like Autosys, but that's expensive and very much over the top for what I want. I've also se...
The only nice way I've found is: import sys import os try: os.kill(int(sys.argv[1]), 0) print "Running" except: print "Not running" (Source) But is this reliable? Does it work with every process and every distribution? ...
Specifically, what commands do I run from the terminal? ...
Because Linux (and its variants) have a completely different set of fonts than Windows and Mac OS X, is there anyone with any experience of creating cross-platform font families - ideally finding equivalents to the common fonts found on the aforementioned operating systems? If so, what is the best route to take? ...
I have 3 Linux machines, and want some way to keep the dotfiles in their home directories in sync. Some files, like .vimrc, are the same across all 3 machines, and some are unique to each machine. I've used SVN before, but all the buzz about DVCSs makes me think I should try one - is there a particular one that would work best with this...
I was wondering if there is a more up to date alternative to libFoundation (which hasn't been updated since 2001) to develop modern cross-platform Obj-C applications. I don't need appKit features, only Foundation is needed. I know about GNUStep, but I've only heard bad things about it. The Cocotron seems nice, but doesn't seem like it ...
Is there any UI library that can be to build both a text user interface (ncurses) and graphical user interface (GTK? QT?) from the same source? I know that debconf can be used with various frontends, I would like to build something similar but programmable. ...
I have an NFS-mounted directory on a Linux machine that has hung. I've tried to force an unmount, but it doesn't seem to work: $ umount -f /mnt/data $ umount2: Device or resource busy $ umount: /mnt/data: device is busy If I type "mount", it appears that the directory is no longer mounted, but it hangs if I do "ls /mnt/data", and if I...
Is there a maximum number of inodes in a single directory? I have a directory of 2 million+ files and can't get an the ls command to work against that directory. So now I'm wondering if I've exceeded a limit on inodes in Linux. Is there a limit before a 2^64 numerical limit? ...
In this question someone asked for ways to display disk usage in Linux. I'd like to take this one step further down the cli-path... how about a shell script that takes the output from something like a reasonable answer to the previous question and generates a graph/chart from it (output in a png file or something)? This may be a bit too ...
