A Linux distribution is an operating system made as a software collection based on the Linux kernel and, often, on a package management system and are available for a variety of systems. A typical Linux distribution comprises a Linux kernel, GNU tools and libraries, additional software, documentation, a window system (the most common being the X Window System), a window manager, and a desktop environment. Most Linux systems are open-source software made available both as compiled binaries and in source code form, allowing modifications to the original software. Over three hundred distributions are in active development, including commercially backed distributions (such as Fedora, openSUSE and Ubuntu) and community-driven distributions (such as Debian, Slackware, Gentoo and Arch Linux).

I have rsync some files to a remote server.  Some of those files have been updated on the remote server and others of those files have been updated on the original server.  

I want to update the remote server so that it includes any changes to updated files on the original server but I don't want to overwrite anything on the remote server that has more recently been changed on the remote server than the original server.

Which rsync option should I use for this?

I read about binary compatibility between Linux distributions, however... Ubuntu and RHEL are usually not compared or even mentioned in regards with each other.

Are they?

Hi.
We want to start building our own chromium browser for use in our Digital signage solution.

We have set up an environment on a Windows PC, and have successfully build a default chromium browser.

We do, however have some trouble finding our way around in the code.

Therefor, maybe som waypoints could help us.

Can anyone tell me, where I could find some code regarding:
The address bar
Tabs
Forward/backwards arrows

A code snippet is enough, or maybe even better in which  files are they.

Also, hints on how to find elements, without having to guess our way through and making searches in Visual Studio, without knowing the name of what we're actually looking for

I have a windows XP that is running on  a 32 bit AMD Sempron 140  2.71 Ghz and 2.75 RAM and looking to convert to Ubuntu or some other linux distro so this can be re purposed.  I would like to have an easy to use desktop for non technical users.

There are a handful of "best lightweight" style articles that I have already read and am looking for personal experience.

Thank you.

i'm trying to install an IRC client on my Debian Gnome Desktop.

Every IRC client comes up with a plethora of unresolved dependencies

i've tried apt-get and the GUI package manager when apt-get didn't want to auto resolve the dependencies.

the GUI package manager lists the app i want to install, then i click the check box to install it, click apply changes, and it looks like the progress bar goes from 0 to 100 real quick, and then it shows the package as installed...

but when i go to run the app, it is missing, and i go back into package manager and it shows not installed

i haven't had this problem before--both apt-get and package manager have been real good to me

thanks for suggestions
