Anyone know a place in the central San Diego area that offers Unix/ Linux training courses?

Q. I'm looking for an instruction program in the central San Diego area (not north, east or south county) that teaches the basic commands and and concepts of Unix & Linux. I think there may be something available at the community college system but would like to use something outside of that if possible.

Thanks

A. Try and surf the following links to get all details

What is the limitations of Linux compared to Windows?
Q. Linux is the alternative to Windows.

However, it seems Linux has its limitations.

What is the limitations of Linux compared to Windows?

What is it that Windows has but Linux lacks?

Or is Linux just as good as Windows?

A. I suppose I can help you with your homework. Let's start by examining your assumptions:

1. Linux is not the only alternative to Windows. Apple's (Unix based) Mac OSX is a very viable alternative, as is FreeBSD. There are other OS's, but few have the capabilities of Windows, Linux, OSX, and FreeBSD.
---
2. The only real limitation of Linux compared to Windows is that most PC games are release for Windows but not Linux. DItto OSX. Worse for FreeBSD. Some software (eg Cedega) will allow you to play most PC games on Linux, but not all, and not really easily. It is harder to sync your Windows Mobile smartphone to Linux, but then it's not 100pct reliable on Windows either. In every other respect Linux is similar or superior in capability to Windows, with a minor bit of retraining.
-----
3. Windows has a massive install base and widespread vendor support. Linux is not as comprehensively understood and supported. This is why people say Linux is harder than Windows, even though you apply exactly the same learning process to Linux that you did to Windows. Many programs are available for Windows that are simply not operable in Linux due to this vendor support.
-------
4. Linux is better than Windows, because Linux is by nature more secure: the way Linux handles users and permissions naturally limits the scope of a virus or trojan. Linux is also free. Linux also does not participate in thinly disguised blackmail. Linux does not promote vendor lock. Linux presents a similar user experience across hardware platforms. Linux allows a user to leverage training to multiple roles rather than isolating user skills from admin skills.

I could go on for days.

How do I save my preferences in Ubuntu Linux?
Q. I am brand new to Linux; I have it booting from my external USB hard drive. I see places to change settings (theme, time, etc.) but there isn't really an equivalent of the "Apply" button, and when I close the windows, the changes aren't saved...

What am I doing wrong?
I have tried pressing Enter, double clicking, all the things that usually indicate a selection.

A. This tutorial on Ubuntu 8.10 Intrepid Ibex shows a close button at the bottom of the screen saver preferences window and i think it's the same as the appearance preferences window.

Changes made here are applied immediately after selecting the changes not with an apply button.

So in that tutorial the screen saver is actually changed when a new one is selected, not after a button turns it on.

Hope this helps.
