Q Can I attach two monitors to my Dell Vostro 220?
A No, it has only one video connector.
The way around this is to buy a video card which supports two monitors. The computer is old but it has a PCIe x16 slot, so there are lots of video cards available.
After installing the card, you then install an “additional driver,” and, if it's an Nvidia card, in “Nvidia X Server Settings” you can set it up the way you want, as necessary. Most likely, when you plug in the two monitors, it will do what you want.
Q I installed Ubuntu 13.10. The other OS was Windows XP. Everything worked OK. Then upgraded to Windows 7 and have lost grub boot loader.
A Use Boot Repair: https://help.ubuntu.com/community/Boot-Repair
Q What is better, a hardware firewall or a software firewall?
A (Thanks to The Fu in the Ubuntu Forums) There really aren't any “hardware firewalls” anymore. Most cheapo routers run Linux and use iptables as the firewall. pfSense is a better firewall than any of the Linux options. It is smarter about tracking connections, and because it is based on BSD, it tends to slow down, not fail, under heavy loads.
Gord adds: modem =⇒ pfsense =⇒ local network works really well for me.
Q I have an Ubuntu server and configured NFS server, but it is not possible to access from any machine in the same network.
A (Thanks to SeijiSensei in the Ubuntu Forums) Have an iptables firewall on the server? If so, you probably don't have port 2049 open.
Q I have a laptop with lubuntu 13.10 with these specifications: 512 RAM, gma900, Intel Centrino 1.6 GHz. Can I use a virtual machine to run XP?
A No, you need more memory.

Tips and Techniques
Solution Options
I recently ran into the weirdest problem. It appeared that my hard drive was packing it in, and eventually, I could not boot Linux Mint 13, my daily driver.
I moved the SATA cable to the other hard drive on my primary system – and Small Business Server (SBS) failed to boot. Huh?
It appeared that the SATA port or the cable had failed, so I plugged in a different cable in a different port, and SBS booted; presto-chango, Mint booted.
I have the luxury of being able to easily try these options, so I solved my problem fairly easily. Most people would have just assumed that the hard drive failed, and would have resorted to whatever the state of their backup was. In many, many cases, that state is dreadful.
So I can reiterate Ronnie's recent message: make a good backup. Backup to DVD, backup to an external drive and backup to the Cloud. But back up!
