I use Mozilla’s Thunderbird e-mail client, and their Firefox web browser. Every now and then, I would need to transfer all my settings from one computer to another, or from one OS install to another. Recently, I was once again faced with this little problem.
In Thunderbird, I used to copy the Mail folder over, the
prefs.js file, and some other odds and ends – but that meant I had to reinstall all my extensions and everything. The same was true for Firefox – minus the Mail folder.
So, the other day, I finally figured out how to transfer ALL the settings over in one ridiculously, stupidly easy step. Why I was unable to find any information about this on the web before is beyond me. Everything I’ve found says to copy files from inside your profile directory as I have been doing, which is entirely unnecessary.
Read on to see how to do it…
I’m going to assume that you know how to do some basic stuff in Linux. In other words, if you don’t know what a command line is, or how to traverse directories, this might not help you much.
I should also note that my preferred flavor of Linux is Ubuntu. These commands will work on Ubuntu, but I can’t make any guarantees for other distributions. Best to just try them out and see what happens!
Without further ado, here are some of the top linux tips and tricks that I have gathered over the years…
If you’ve ever had the pleasure of upgrading old electrical wiring in a residence, you know that a separate earth ground wire was generally not used in the past. In such cases, you find yourself with 2 wires: live, and neutral.
Now, you might want to install a grounded outlet without redoing a lot of wiring. A common method of getting around this little problem is to install the new 3-conductor outlet by tying live to one prong, neutral to the other prong, and then using a jumper wire to connect neutral to the ground connection inside the outlet.
“Theoretically, this should work just fine!” you reason.
It turns out that theoretically, you are in fact correct. Practically speaking, adding a “ground” in a 2-wire installation by tying neutral and ground together has several serious – and possibly dangerous – drawbacks.
Here’s the scoop.
How Does it Work?
Never let children use a chainsaw!
Let’s face it: everyone loves chainsaws. A chainsaw can make very short work of any trees, bushes, or branches that happen to be causing a problem. I have even seen a small chainsaw skillfully used in place of a large circular saw for home remodeling – no electricity required! They are seriously handy devices.
The one problem with chainsaws is that they require maintenance. In fact, they require a lot of maintenance in order to perform optimally. A lot of “service” shops really don’t do a very good job of taking care of saws. If you can find a service shop with an old guy who still uses files to sharpen chains, then you have discovered a true gem!
For the rest of us, you can save some bucks – and have a lot of fun – by servicing your chainsaw yourself.
I’m sure you’ve all heard some hype about 64-bit this and 64-bit that. The thing I read the most is that a 64-bit operating system or piece of software is automagically twice as fast as a 32-bit one. Not so. Worse yet, some operating system vendors market their product as having an “advanced 64-bit architecture”, when the truth of the matter is that their OS is not fully 64-bit.
In any case, most people today are using a 32-bit operating system, but a surprising number have already switched to a 64-bit OS. Or in some cases, a quasi-64-bit OS…
There is one true reason though why you will actually want to switch to a 64-bit OS in the near future: the infamous 3GB barrier. Just what the heck is this mystical barrier, and why should you care?
