  • Linux Kernel - Integer to ASCII

    - by DRX-Z
    I need to convert an integer to it's ASCII representation from within the Linux Kernel. How can I do this? I can't find any built-in conversion methods. Are there any already in the kernel or do I need to add my own?

  • I need to cut a portion of a string in linux

    - by Abeed Salam
    I have a file in a folder like this: installer-x86_64-XXX.XX-diagnostic.run The XXX.XX is a version number and I need the version number only. How to do it in linux? I have this code: #!/bin/bash current_ver=$(find /mnt/builds/current -name '*.run'|awk -F/ '{print $NF}') So this gives me just the name of the file correctly (minus the location, which I dont want). But how do I only get the XXX.XX version number into a variable such as $version

  • What speech libraries are available in Linux?

    - by George Edison
    When it comes to TTS (text-to-speech) libraries in Linux, what choices do developers have? What libraries ship with the majority of distros? Are there minimal libraries? What functionality does each library offer? I'm approaching this primarily from a C++ point of view, although Python would suit me too.

  • Creating a "virtual" path (/bla) in Mac OS X and Linux that calls custom code

    - by Michael Stum
    Just something I'd like to play with, I would like to create a "virtual" file/directory in the File System of Linux or Mac OS X (Not sure if I can share the same code - does POSIX help?), for example /foo and then perform custom code when something is read or written to it. Similar how /dev/null allows for stuff like echo "Hello!" > /dev/null I don't care if it's in /dev, /proc or anywhere else, as said it's mainly something to play with...

  • Linux directories

    - by Alex Farber
    I am writing installation script for my program, which is supposed to run on Linux/Unix OS. What is the default directory for the following files: Executable files (programs). Program should be executed by typing its name from the command line. Shared libraries. Third-party shared libraries (the program is not open source, so I need to redistribute third-party libraries). Read-only program configuration files for all users. Configuration data available for read/write access for all users.

  • Remote Desktop in Linux like Team Viewer

    - by crissangel
    For Remote Desktop Sessions in Linux, I want to know if there something available equivalent for what Team Viewer does for windows? The main advantage I find of Team viewer is that it can bypass firewalls, needs no NAT configurations or port forwarding rules to be setup in the router.

  • Linux tool to send raw data to a TCP server

    - by paul simmons
    Hi, I am aware that this is not a direct 'development' question but I need that info to test a development project, so I think someone could've hit similar problem. I will test a software that runs a TCP server and according to sent commands replies some answers. I will test the software and do not want to write code if it doesn't work well. So I want to send those commands and test drive the server software. How can I achieve this with a Linux box?

    - by Daniel Stevens
    I'm a Linux user looking to write a program which will pick up the phone, dial a number, play a recording and record what the person on the other end of the line says and save it to an audio file. I will want to use the modem that came with my computer if possible. What should I use to write this program?

  • question about a macro in Linux Kernel List implementation

    - by holydiver
    I generally have ignored using macros while writing in C but I think I know fundamentals about them. While i was reading the source code of list in linux kernel, i saw something like that: #define LIST_HEAD_INIT(name) { &(name), &(name) } #define LIST_HEAD(name) \ struct list_head name = LIST_HEAD_INIT(name) (You can access the remaining part of the code from here.) I didn't understand the function of ampersands(I don't think they are the address of operands here) in LIST_HEAD_INIT and so the use of LIST_HEAD_INIT in the code. I'd appreciate if someone can enlighten me.

  • Autorun a removable device in Linux

    - by Zloy Smiertniy
    I have a removable device setup so it autoruns when plugged into a Windows machine and pops up a message giving the owner's information, so it can be returned if lost. Is there a way to do this in Linux as well? It doesn't need to be complex, it can be an option in a right-click menu, or a splashscreen, or anything.

  • Get the layout mode (landscape or portrait) of a pdf from php/linux

    - by Jonathan Hendler
    Given a PDF, how can one get the layout mode of a PDF (or relative width/height) using a PHP lib or linux command line tool? Using http://www.tecnick.com/public/code/cp%5Fdpage.php?aiocp%5Fdp=tcpdf which can set this variable on new PDFs, but for existing pdfs from adobe. Thought of converting pdfs to ps, or using gs in some other way - like converting it to an image first, and getting the width and height of that. Is this the best way?

    I am setting up a new SVN server on Ubuntu Linux. Where is a good place (best practice) to put the repositories? Should I create a new user? The server will be accessed via http:// so no need to create user accounts etc (as was the case for svn://). Many thanks in advance
