LINUX IS CONFUSING. THESE ARTICLES SHOULD HELP.
If you’ve been using the default movie player in Ubuntu to play videos, you might have noticed that there’s no way in the application to clear the recent history of watched movies. This could cause issues if you happened to open a video that you don’t want other people to see in your list.
Don’t get me wrong, I think the mouse was probably the greatest innovation in computing since the silicon chip, but for a power user it’s really the slowest form of input. Taking your hands off the keyboard to reach for your mouse takes easily 500 ms of time, if you’re fast. Add to that the time to actually find the cursor (no small feat on high resolution screens), and the time to find and click on that one tiny icon you need, and you’re talking some serious productivity cramping. Of course, you could always be one of those *nix rebels who refuse to use any graphical environment, but what’s the fun of using bash, VI and command-line compilers for the rest of your days?
So you are using the killer Amarok music application under Ubuntu, but when you try to “Burn this Album”, the menu item is grayed out and otherwise disabled. The reason for this is because Amarok is a KDE application designed to work with K3b, the cd burning application for KDE, but it’s not installed by default in Ubuntu. (For that matter, neither is Amarok)
Most of the time, when I download something it’s a file archive of some kind – usually a tarball or a zip file. This could be some source code for an app that isn’t included in Gentoo’s Portage tree, some documentation for an internal corporate app, or even something as mundane as a new WordPress installation.
How many times have you noticed a file sitting in a directory and wondered… where did this file come from? Or you are trying to tell a friend how to use a utility but he doesn’t have it installed, and you can’t remember what package you installed to get it.
My favorite feature in the latest version of VMware Workstation is that you can run virtual machines entirely in the background. This is most useful for “appliance” machines that you won’t actually use from the prompt, but through a web browser or ssh client.
A very common task for a web developer is uploading a single file from a subdirectory on your development box to the same subdirectory on a remote server. Unfortunately, this always ends up being an annoying manual process involving switching directories on both servers, and wastes a large amount of time.
Microsoft’s SQL Server has a tool called Profiler that you can use to monitor every SQL query that hits the database. This is extremely useful for programmers as well as database administrators to troubleshoot the exact queries generated by an application.
If you’ve tried to use the built-in “Extract Here” functionality in Ubuntu’s File Roller to extract either a single or a multi-part zip or rar file and ended up with a “Password required” error, then you might just assume the files are password protected when in fact they are not.
Ubuntu includes a very limited shortcut key configuration utility which doesn’t allow you to assign hotkeys to your own applications or scripts. To get around this limitation, we can use the built-in gconf-editor utility to assign them ourselves.
As a webmaster, I’ve often wanted to be able to see real-time hits as they arrive. Sure, Google Analytics is a wonderful package for looking at trends over time, but there’s a delay of a few hours there, and you really can’t see data like requests per second or total bytes.
If you run a dual-boot system with Linux and Windows, this has happened to you. You had to do your monthly reinstall of Windows, and now you don’t see the linux bootloader anymore, so you can’t boot into Ubuntu or whatever flavor of linux you prefer.
The find utility on linux allows you to pass in a bunch of interesting arguments, including one to execute another command on each file. We’ll use this in order to figure out what files are older than a certain number of days, and then use the rm command to delete them.
If you’ve installed Suse using the CD/DVD installation, the default setting is for software installations to load from the cdrom instead of off the internet repositories. Since I’m always connected directly to the internet, I’d much prefer to download and install from the net.
