While comparing java TCP socket performance between RH Linux and Solaris, one of my test is done by using a java client sending strings and reading the replies from a java echo server. I measure the time spent to send and receive the data (i.e. the loop back round trip). The test is run 100,000 times (more occurrence are giving similar ...
I am writing a c++ program on Linux (Ubuntu). I would like to delete the contents of a directory. It can be loose files or sub-directories. Essentially, i would like to do something equivalent to rm -rf <path-to-directory>/* Can you suggest the best way of doing this in c++ along with the required headers. Is it possible to do this...
This may or may not being a coding issue. It may also be an xinetd deamon issue, i do not know. I have a python script which is triggered from a linux server running xinetd. Xinetd has been setup to only allow one instance as I only want one machine to be able to connect to the service, which is therefore also limited by IP. Currently...

Hi all, I was working on the Linux box A and I run this: grep '^\S*\s-' access_log That displayed some lines, as expected. Then I moved to the machine B and I launched exactly the same command. But this time it didn't work. I had to launch this in order to get done what I needed: grep '^[^ ]* -' access_log Before succeeding, I...
Hi guys I would like to know if anyone meet a similar situation. What are the reasons for a company to decide that you must develop using Linux environment (virtual machine) and not Windows environment? Here there's no workstations with Linux at all - all computers have Windows installed. There's one production Linux server. Is it ...
I would like to be able to print to a number of remote printers from a website. The website runs on a Linux server, and it is the application within the website that generates the print jobs. The remote printers are located at a number of broadband sites. The printers will be serial receipt printers or USB printers. There will most like...
On a Linux system it is typical to type progname --help in order to view the help output for that program. After this you will see a description like: progname [SWITCHES] [FILES]... [ETC] My question is; is there a standardized syntax for his sort of (command-line use) documentation? In order to describe things like optional switches...
So here's the problem, I'm reading a level file for my game, works fine under linux: @0 @12 200x200 version 3 @16 973 blocks @989 @993 18 zones But under windows I get the following result: @0 @212 200x200 version 3 @216 973 blocks @1200 @1204 18 zones Uh? The windows ftell stats with an offset of 200? Reading the file apparently y...
This is about me being stressed by playing the game "type a command and remember to prepend sudo or your fingers will get slapped". I am wondering if it is possible somehow to configure my Linux system or shell such that when I forget to type e.g. "sudo apt-get install emacs", instead of just telling me that I did something wrong, gksud...
Business as usual: I've logged into my Linux machine from my MacBook Pro using NX, opened a terminal, and ... key bindings with M- (Meta-) do not work. (Talking about bash, of course.) Wait for it. I'm using a PC keyboard hooked up to my Mac (I cannot work on a cramped laptop keyboard). So I decided to investigate: used xev to capture ev...
I am studying a sound converting algorithm where an array of signed shorts is received. At a given point in the algorithm it converts the samples from 16 bits to 14 bits, and it does it like this: int16_t sample = (old_sample + 2) >> 2; For me its clear that the shifting is needed as we want to get rid of the least 2 significant bits,...
Hello all, I am using Selenium to conduct user interface tests with JUnit, in a Maven project. The project is located on a Linux box running IEs4Linux and Wine to allow us to run the tests in IE. Right now I'm using Xming along with Putty to view the virtual browser windows, and I am able to open an IE window with the command "ie6", an...

Hi, I am writing a program that repeatedly does an operation till Ctrl+C is hit by the user in the Linux terminal. I am programming in C. Any ideas how i can implement this. I have tested my program by using "for" loops with a condition but now i want to make it run as long as Ctrl+C is hit by the user and interrupted. What I was thin...
So I have a tty (let's say /dev/tty5) and want to know whether it currently is a controlling tty of a process group or session, or whether it is currently unowned. POSIX has two API functions which suggest themselves here: tcgetpgrp() and tcgetsid(), both of which only work however if the caller has the tty as controlling tty -- which in...
I am trying to run ffmpeg via the exec call on linux. However I have to use quotes in the command (ffmpeg requires it). I've been looking through the java doc for processbuilder and exec and questions on stackoverflow but I can't seem to find a solution. I need to run ffmpeg -i "rtmp://127.0.0.1/vod/sample start=1500 stop=24000" -re -...
I am developing under Linux with pretty tight constraints on disk usage. I'd like to be able to point logging to a fixed-size file. For example, if my application outputs all logs to stdout: ~/bin/myApp > /dev/debug1 and then, to see the last amount of output: cat /dev/debug1 would write out however many bytes debug1 was setup to ...
