LINUX IS CONFUSING. THESE ARTICLES SHOULD HELP.
I have played with various distributions of Linux for the past 5 years. I would dabble in Red Hat running a web server, install Mandriva (Mandrake at the time) in a dual boot with XP, and actually build a kiosk for a tech school in my area using Suse Linux. I have also ran various versions on Virtual Machines over Windows many times. I have always had a love / hate relationship with Linux. When I could get things working it was great! However, when I just needed something like my SoundCard to work, I would find that 2 hours of compiling a driver just wasn’t worth it.
If you do a lot of tweaking to the panels in Gnome or KDE, you’ve probably run into an instance where you enabled a plugin or changed a setting and need to restart to see the effect (or maybe you locked something up). Instead of logging out or rebooting, we’ll just reload the process.
I decided to upgrade my Mac Mini to Linux over the weekend with excellent results until I encountered an extremely annoying error in Firefox: “Additional plugins are required to display all the media on this page”. Going through the wizard a dozen times didn’t fix the problem, so what gives?
If there’s one thing that drives me crazy about using multiple operating systems, it’s the inconsistency in keyboard shortcuts… when you hit the backspace key in Firefox on Windows it normally goes back to the previous page, but it doesn’t on Ubuntu Linux.
When you are trying to work on changing the design of your website, you have to be concerned with the width of the pictures in your article content. I’ve got notoriously large screenshots on most of the articles I’ve written, so if I want to increase the sidebar it’s critical to figure out which pictures are going to be too wide to fit in the new design.
Whether you are responsible for a server or just a programmer doing development, you’ll often have more than one logfile that you want to track at the same time. There’s a nifty little utility for Linux called MultiTail that allows you to monitor multiple logs in a single window, instead of requiring multiple separate shell windows open.
Ubuntu Gutsy is the latest major release of the most popular Linux distro, released on October 18, 2007. Like all Linux distributions you can upgrade easily even while the release is in beta, but now that it’s been released you should have much better luck with it.
Has this ever happened to you? I created a new virtual machine running Ubuntu on my VMware server before I left home, but forgot to install the ssh server… so I couldn’t get to that machine at all from my remote location. Rather than driving back home I decided to find a solution.
While working on the instructions for compiling MonoDevelop from source, I relied heavily on the dpkg and apt-cache commands to tell me what was already installed vs what packages were available in the repository. After completing that article it occurred to me that I should explain how to show what packages are currently installed… so here we are.
After reading a post from my friend Daniel about the new release of MonoDevelop, I decided to try and install it… which is when I realized that the installation from source is so painful I’d better figure it out and share it with everybody else.
One of the biggest security holes you could open on your server is to allow directly logging in as root through ssh, because any cracker can attempt to brute force your root password and potentially get access to your system if they can figure out your password.
If you like the way Ubuntu requires you to enter your username and password instead of clicking on an icon, you can enable the same thing for Windows Vista in a somewhat similar style logon process. This is really most useful for home users, as domain users should already see this screen.
If you’ve got an Ubuntu machine that you initially installed with Ubuntu Desktop, but would like to run as a server, you can just disable the graphical environment from starting up in order to save resources. This is also useful for doing system maintenance from the command line that needs to be performed outside of the GUI.
One of the things in Ubuntu that has always driven me crazy is the addition of new items into the grub menu without removing the old entries that likely don’t even work anymore. I’m sure most experienced Ubuntu users already know how to do this, but here’s the method anyway.
Virtualization Technology (VT) is a set of enhancements to newer processors that improve performance for running a virtual machine by offloading some of the work to the new cpu extensions. Both AMD and Intel have processors that support this technology, but how do you tell if your system can handle it?
I’m the type of geek that has an SSH client open at all times, connected to my most frequently used servers so that I have instant access for monitoring and anything else. As such, it irritates me greatly when I get disconnected, so I’m sharing a few methods for keeping your session alive.
