I've been a computer hobbyist since before the IBM PC, and a professional programmer not too long after that. I've had experience with electronic repair, manufacturing, and testing of professional audio.

I tutored other students in Fortran before PCs existed, built my first computer from bare circuit boards and reject parts (S-100 CP/M system), and transitioned from stereo repair, to professional audio manufacturing at Dolby Labs, where I set up the automated functional testing for Dolby professional equipment. From there, I went into programming full-time as a C programmer for Mac presentation graphics systems, then to Windows C++ video programming. My last 10 years was as a C++ Windows software engineer for a corporate source code control system.

I'm now a Linux user, retired from active work but still helping friends with computer problems, configuration, audio/video setup, and other electronic devices.

comment What is the exact difference between a 'terminal', a 'shell', a 'tty' and a 'console'?
The command line is simply the language used to send commands to the command-line interpreter running in a shell from the terminal/terminal emulator.

comment Not able to configure phpmyadmin in Ubuntu 12.04
This isn't an answer because I don't know anything about any lamp wrappers, but it looks like Apache may not be running, or you are not connecting correctly. Apache is responsible for intercepting php files and translating them to HTML, which is all the browser understands (besides JavaScript).

comment Gnome, KDE, XFCE… which is most simple and customizable?
I think they all are capable of most of what you want, but some may take more work than others to learn and implement the features. I personally use Gnome classic with Compiz and dual monitors, and I use the keyboard a lot. There are shortcuts for moving windows between monitors, to various places on one monitor (like top half, left half, middle full screen, etc. There's also keys Expo, etc. And I believe they all have clipboard managers.

comment Clock skews on remote machines
NTP is the standard for time sync. There were utilities that calculated the drift years ago; I remember source code for Unix at the time, but I don't remember right now what the names were. Search for time synchronization and correction.

comment ssh localhost without password doesn't work on Fedora 14
FWIW, I always use two commands: 1. ssh-keygen -t rsa (or dsa), then 2. ssh-copy-id "username@hostname -p" for rsa. I don't usually use dsa, but I think the second command is something like ssh-copy-id -i /homedirectory/.ssh/id_dsa username@hostname -p.

comment Partition not mounting from fstab
Both of these are good comments, and I wanted to second the 1st suggestion. Using mount -a is almost always a good habit to check the validity of fstab. The reason it is good is that it will immediately list any errors it finds, so you not only know whether the file is valid, but if it isn't, you know what the errors are, which, of course, is a nice first step to solving the problem.

comment SSH into Ubuntu VM remotely
I'm slightly confused about what's running where, so if I'm off base, forgive me; but... For troubleshooting, you could temporarily install an ssh demon on your main system (Ubuntu?), and see if you can connect to it from outside. That would let you know if it's getting through the router. Then you might be able to troubleshoot (if needed) from the main system to the VM to make sure that part is working.

comment Add blinking network-monitor icon to GNOME / XFCE
I'm don't know XFCE, but Gnome2 and Gnome3 in classic mode has a panel applet called "System Monitor" that can be set to show a graph of that information, where you can choose the colors for each; I have green for incoming, and red for outgoing on mine.

comment mounting to non-empty directory, then later deleting original files
Well, your answer was good, but the assumption wasn't. :) I wasn't running out of space, but I wanted to avoid that possibility in the future. I had plenty of unused space on my drive, along with several used and unused partitions to play with, so I decided to do this more as something that seemed like a good idea. I used the tip from @jippie before I saw your post, but both seem to be similar. Yours was more detailed, but I didn't really need details too much, just the idea was enough. Thanks for the post

comment mounting to non-empty directory, then later deleting original files
Well, that worked out perfectly - amazing that it was that easy. I used the command sudo mount --bind / /mnt/temp to mount the filesystem, and deleted the files with no problem, after confirming that the timestamps were different than /var, to make sure it was indeed different. Thanks for the tip.

comment mounting to non-empty directory, then later deleting original files
Interesting idea - So, I'll see the "real" /var directory doing that, instead of the mounted one. If that's true, then this method is much more straightforward than any other ideas I saw in my research for accessing the original files when mounting on a non-empty directory. I'll check it out and come back later.

comment Permissions/ownership of /usr/local/bin
Good answer; I thought maybe I'd add my 2 cents worth. Even if you are the only user now, this could change in the future, and it's a good idea to follow best practices all the time. If you have a personal script only for yourself, put it in ~/bin; if it's something others might use, put it in /usr/local/bin. Others could mean yourself, in a different account, too. And, remember, some of the rules protect you from yourself, to make it harder to delete important files.

comment How do I make sure grub is only installed once?
Did you ever resolve your problems? I'm looking into doing something like this, and came across this article that looks interesting, if it's accurate; so I'm looking for feedback on it, or suggestions in general before I waste too much time... article

comment About to replace windows with Ubuntu 11.10. Will this cause any problems?
Well, I'm not totally sure what you did, but I'm glad it seemed to work out. There are usually a number of ways to accomplish things in Linux once you understand a few basics. You probably learned some of those during this experience, and soon it will not seem hard. Unfortunately, you will probably learn a few things the hard way along your journey. :) But if you avoid things like WUBI, it will be much easier.

comment Downgrade Gnome 3 to Gnome 2
Might be nicer to either say what cinnamon actually is, or give a link that explains it. The link you gave tells nothing about what it is anywhere on the site. Simply saying it's "neat and non disruptive" would describe any one of the available GUI options, depending on the opinion of the user, would it not? Also, you imply that it is not gnome, yet my understanding is that it is a fork of the gnome 3 shell. I can't see much advantage over Gnome3 classic, unless you like the Mint Menu.

comment About to replace windows with Ubuntu 11.10. Will this cause any problems?
Sorry, no, I meant run the WUBI installation, not install. So while running it, you can copy data over to the new partition, or to a backup of some sort.

comment OpenSSH, chroot user: Root needs to own the user directory, is there any consequence?
Is there a reason you don't use the standard file permissions? Linux/Unix was designed to be multi-user, and has the ability to easily grant or deny access to some or all of your directories with permissions for you, your group, and everyone else. Just make sure you don't add your friend to the sudoers list.

comment Keyboard only desktop environment
Well, I haven't actually tried either of those. I use Vim extensively as a programmer, but most people don't like that sort of interface. I personally would not like to use a browser without a mouse, although it's better than not using it at all, like if I had a laptop, and the touchpad stopped working.

Sure, and I used to use Lynx in the early days of the web before graphical web browsers. It's worth bringing up, but don't be too surprised when most people look at you like you just stepped in a big pile of ... well, lets just say they may look at you strangely.

comment Keyboard only desktop environment
But most people do things other than playing around with their windows and desktop, like web browsing, etc. A tiling window manager won't change that, will it?
