is the linux for dummies 9th edition book a continuation of the other editions?

Q. I'm went to buy "linux for dummies" today at the book store and noticed that it said 9th edition on it. Does this mean that its just a rewritten,updated version or does it mean that you also need the 1st through 8th editions for it to make sense? in other words, can i buy this book without having to buy the others and still learn all i need to know?

A. It could mean it's been revised 9 times, therefore making it 9th edition, or it is as you said, i am unsure.

What is the best way to run Windows and Linux simultaneously on the same machine?
Q. I don't want to run one system inside another using an emulator or similar system.

I want a system that can run both OS's simultaneously and that I can switch between them.

Today I have both systems on my computer, but I need to shut one down to use the other.

Thank you.

A. You are talking about a virtual machine. There are pros and cons with that system.
Pros You can move back and forth between OSes without rebooting.
Cons If you host OS becomes inoperable (e.g. windows gets a serious virus) you will lose both systems, also if your computer does not have enough resources (ram and cpu power) it can run both OSes more slowly.
There are 2 free virtual machine: vmware and virtualbox.
The first link explains how to run linux in a virtual machine in windows.
The second explains how to windows 7 in a virtual machine on Ubuntu.
You should google both vmware and virtualbox to see which might suit you, and google "install windows 7 on virtualbox linux" to get more info and youtube videos.
Hope this helps.

What is good recording software for linux?
Q. Ive recently started useing ubuntu linux, because it runs better on my computer than windows. Any suggestions for good music recording software? I have An electric keyboard, electric guitar, electric, bass, electric drums, and a sampler (turn tables). Id like something flexible so i can use them all on the same software.

A. Audacity is a the easiest to get jump started and most likely to have drivers for your break out box.

There are several others. If you do a lot of Midi work I suggest Rosegarden. Keyboardists especially tend to favor Rosegarden. I love the interface, full featured but can be picky about which break out boxes it talks too.

Aurdor is another full featured recording software but it's interface is more like Pro Tools while Rosegarden more closely resembles Cakewalk.

Those are the 3 I'd start with. The best way to get them is through your favorite package manager. Synaptic is one of the better ones. Just do a search in synaptic for these packages. They take care of the dependencies for you. Makes installing software on Linux the easiest platform in the world to install software for. Audacity, Rosegarden and Aurdor are all listed in the Multimedia(universe) section in Synaptic. Just check them say yes you want ot install and it's dependencies. Then click on apply when you have selected all the packages you want to install.

You'll also want a good tagger. Easy Tag is solid, I personally prefer Kid3, but there are dozen good ones and Ubuntu comes with Gtag I think it is by default. You should be able to edit ID3 tags through your file browser thought that is a bit tedious.

Installing Lame is a must. If your terrified of a command line you'll also want a Lame front end but to be honest using lame on command line is a no brainer. Open a term window, lame -vbr (name of wave file you want to convert to a mp3) (name you want the MP3 to be)

lame -vbr something.wav something.mp3

This mp3's it using variable bit rate which gives you the best compromise between sound quality and compactness of the output. Most mp3s you download today use lame and it's vbr setting. You get 256k quality where it counts but where there's lots of quiet you get higher compression ratios usually saving a couple megs on the final output without reducing the quality any.

There are dozens of Lame front ends to let you do that without using a command line. Just search synaptic for lame and you'll find them. Audacity, Rosegarden and Audor will plug into Lame and allow you to output MP3s directly as well once you have lame installed. Personally I like to hand rip my stuff, then tag it w/mix & version. Then rename & retag anything I'm sending out to people or the public. Saves listening to 10 copies of the same tune to find that ONE mix you were looking for.

As for sampler software, again there are programs similar to Acid and you can use Rosegarden and Audor though they are not designed for it to do some of it. I don't sample so I can't recommend which are best of breed in that area.

What break out box you have is the trickiest part. I suggest using Maudio or going direct through USB if that's an option. Maudio is decently supported in Linux. Avoid Tascam, nearly impossible to get Linux to talk to a Tascam device.
