When opening ubuntu live cd it appears to me as an operative system. Can it replace an os OR SHOULD IT BE USED ALONG WITH A SUITABLE OS? If it is the second option then what system to adopt? At present Ihave an XP prf.
View 3 Replies1) Write a C program using the fork() system call that that generates the Fibonacci sequence in the child process. The number of the sequence will be provided in the command line. For example, if 5 is provided, the first five numbers in the Fibonacci sequence will be output by the child process. Because the parent and child processes have their own copies of the data, it will be necessary for the child to output the sequence. Have the parent invoke the wait() call to wait for the child process to complete before exiting the program. Perform necessary error checking to ensure that a non-negative number is passed on the command line.
2) Repeat the preceding exercise, this time using the CreateProcess () in the Win32 API. In this instance, you will need to specify a separate program to be invoked from CreateProcess(). It is this separate program that will run as a child process outputting the Fibonacci sequence. Perform necessary error checking to ensure that a non-negative number is passed on the command line.i have done with Fibonacci sequence .but i dont know how to include tht fork() function and win32 api .any one can help to finish?
i just can't know how to get it work.
Code: #include<stdio.h>
main()
{
int _res;int i=3;int b=5;

printf("%d",_res);
}

I know a couple of small ones for windows systems (nosee, dscrypt) but i wonder if there is any i could use on both linux and windows OS. the idea is to be able to carry it on USB key and the programme (or probably there will have to be 2 versions of it) would run either on windows or linux os and i could decrypt and encrypt the file if i needed to. no matter on what system i plug the USB key to.

View 7 Replies View RelatedI discovered that if you install directFB (a framebuffer display library magic thing) you can run "links -g" which makes an attempt to be graphical, but it's still not quite the same as a normal browser... I was wondering if there was any way to run an X server for a single programme, or an equivalent solution. Essentially, what I'd like to be able to do is run, say, "startx firefox [URL] and for an X server to be created solely to run my firefox instance. Obviously, the current behaviour (at least, in Ubuntu, as I haven't installed X on Gentoo) is to bring up a graphical login screen, allowing me to start an entirely new X session. Is there a way to do this, or is it just "not how X works"?

View 9 Replies View RelatedWhen I enable UFW Configuration, in a programme called Firewall Configuration, runs along with the System. Now, I configured it such that it can run along with the Session. Now, Ubuntu is already secure. So, is there any need for additional Firewall like this? (ufw is already present in Ubuntu, and this only Configures it). And, is it required to have it enabled always for keeping the Firefox running? (Because It may consume System Resources). Or, is there any other firewall that consumes less System resources or runs at the Background?
View 1 Replies View RelatedMy Ubuntu system is occasionally becoming very sluggish. I'm running many things simultaneously and it's very difficult to tell which program is the culprit.
I suspect that the sluggishness is due to disk activity since the CPU usage is consistently under 50% on each of the 4 cores of the CPU, and over 30% of the 6GB of RAM are free.
Is there a tool that can show me in real time the number of disk IO operations per second and the amount of data read/written per second? Can all this info be broken down and displayed per process?

I'm using my Linux (SLES 10) server as a File Server at this point. I need to set File Permissions to nested folders differently to different groups. For example:
homesharedengineering* should be read only for groupA
homesharedengineeringadmin should be read & write for groupB Plus read only for groupA
homesharedengineeringautocad should be read & write for groupC Plus read only for groupA
I've been using Webmin and Putty to set permissions but Putty only allows me the Default Group, it won't allow me to set several groups on the same directory. Webmin seems to allow me to add multiple groups (Webmin --> Others --> File Manager --> Info & ACL tab will provide extended abilities) but when I add multiple groups, they don't seem to take effect? I'm wondering if my setup at the 'Share' level or at the hierarchy of my folder structure (unix based) needs to be set specifically?

View 2 Replies View RelatedII'm a front-end web developer, I've always developed on Windows with technologies like XHTML, CSS, Javascript and Flash, I've dabbled with PHP and MySQL. I am well used to Windows workflows and tools, from Photoshop to Notepad++, Filezilla and WAMP server stacks to After Effects, and a swathe more - but always on Windows.I'm at a point where I think I need to start seriously developing on a Linux box, specifically at the moment to create web apps based on Node.js, but compiling tools and programs has become a task I'm more frequently required to do.
My question? I need to get my hands on a user-friendly install of Linux, but which one? I need common interface developer tools (lists welcome) to replace... well as many tools I have on Windows as possible.I need to be readily connected to the internet, I need OS updates to not destroy my workflow by crashing the OS, as I've seen Ubuntu do to various friends. I want efficiency, I need to be able to customise what I need to in order to perform development tasks.I guess this could be a long list, but - I don't have practical working knowledge of the Linux OS, nor how it "compares" to Windows (excuse my faux pas). I'm obviously willing to learn, but I'm far, far more keen to just... continue interface development, just on Linux instead of Windows.
A friend of mine helped me set up a server which includes Squirrel Mail.It?s CentOS 5.3.I have a person who would like to access Squirrel Mail at remote sites.My questions is, I can create an account on the server which has KDE and the usual general applications and he would have the remote access Squirrel Mail but he doesn?t need nor does he want to access KDE or anything else on my server. He just want an account so he can use Squirrel Mail.
View 1 Replies View RelatedI have the impression that not that many people understand the scope and limitations of GNU General Public License. This is somehow my basic understanding of it. If I take a program covered under the GNU license, first of all I have the right to get the source code. Second, I can modify it at will. Third, I can redistribute it as will too but the new code will necessarily will have the same GNU license. This made me wonder how people actually can charge for software derived from Linux, for instance, Red Hat. Well, my impression is that they really make profit only out of services. In this thread [URL] I think I found a lot of confusion, even from a moderator (not intended to offend). Red Hat is based on Linux and it is necessarily covered under GNU. Somebody probably bought the program from RHE and can make it available at no cost.
Nevertheless, the moderator decided to warn the user. In this article [URL] it says the following:"Our training is not designed to promote vendor lock-in. Though these courses are based on Red Hat Enterprise Linux, the source code for [RHEL] is available to the community via the GPL [GNU General Public License]," said Red Hat spokewoman Leigh Day. This thread [URL] shows yet more confused people. Is there is a glitch in this type of license that prevents programs like RHEL to be redistributed for free? Why their license page doesn't mention GNU license? Or the problem is just that people get overwhelmed by this license and are afraid to be penalized and get paralyzed? By the way, RHEL is just the example. The key question is about the license!!

View 2 Replies View RelatedWhat is the general opinion of the Mandriva and Debian distros? Mainly asking what kind of user you consider the distro to be for (beginners, advanced, total newb, whatever), and whether you think they offer as much to an extremely experienced user as they would to a newb.Those are my two favorite distros, and I really like Mandriva a lot. I'm trying to pick one to stick with throughout, but I'm not really sure if Mandriva is too automated and Windows-user oriented like Ubuntu (I haven't really delved into the deeper aspects of Linux so I have zero experience in this area now). This might sound a little elitist but I don't want to be using Mandriva and just be automatically dismissed as a newb on first impression just because I'm using Mandriva (although admittedly I am a bit of a newb at the moment, I don't plan on staying one).
