I'm still finding my way with Linux, but this looks like a good resource for local help.

Various people have had the bright idea to use this spare capacity to solve difficult problems. One of the best known projects is SETI@home that analyses radio signals for signs of alien intelligence. I ran that briefly, but have dedicated much more time to distibuted.net (mathematical proofs and code-breaking challenges) and grid.org (medical research). I've clocked up several years of processing for each of them.
I don't get paid for this or anything, but I like the feeling that I am contributing to possibly worthwhile causes. I've recruited others to the cause and am always trying to bring in more people. For grid.org I started a team called Whizz for atomms (a Gerald Searle reference). Feel free to join us.
I know some people will worry that these programs could pose a security risk, but I'm very wary myself. I check various forums for any potential issues before installing anything. I've not heard of issues with either of these. Some people have found that they can affect their PC performance, but I've not noticed this. Mail me if you have questions.

I go along with most of that, but I'm not quite as paranoid as him. Maybe I've been lucky or I could have been hacked without knowing about it. My move to Linux should help matters a little, but I still need to be careful.
Generally the internet is fairly safe if you stick to sites you know with good reputations. Have a read of his hints and you should be okay.
Let's be careful out there.

Mozilla provide Firefox (web) and Thunderbird (email) as I was using on Windows. Both have reached version 1.0 now and work well.
OpenOffice continues to satisfy my word processing and spreadsheet needs.
GnuCash replaces Quicken to the limited extent I use it.
gPhoto talks to my Kodak digital camera. I'm still sorting out a tool to organise the resulting pictures. My Sipix webcam does not seem to be very well supported on Linux.
My Canon i455 printer is partly working using a driver for a different printer, but it comes out a bit faint. There is no specific driver for mine apart from the commercial Turboprint. I used that on the Amiga many moons ago. I may consider it if there is no alternative. I need to get the scanner working, but I believe my Epson is supported.
I've been trying some simple programming using Python. It's a neat little language that I want to learn. So far I've just done a bit of encryption, but one day I may write proper applications with GUI etc, just for fun.
So generally it's going well. The rest of the family can use it without having to know it's not Windows. The kids still have a Windows 98 PC for games and web. The other PC is still awaiting fixing, but can be persuaded to boot when needed. I have lots of data on there that will not fit on the others. I need to invest in bigger disks, but that's for after Xmas.

The basis of my encryption options is GPG (Gnu Privacy Guard, descended from PGP, Pretty Good Privacy). This uses public key encryption techniques. This means that you can freely publish a key for people to encrypt messages to you with, but only you can read them with your secret key. One of the interesting concepts is that other people can 'sign' your public key to say that they confirm that you are who you say you are. Yesterday Simon and I met up with Rob from Rotterdam to exchange keys. This was coordinated via Biglumber.
There are utilities for most email clients that allow easy use of GPG. My chat client of choice, Psi, can also use it to encrypt instant messages. Simon and I are using that now. I just need to bring some of my other contacts up to speed.
I don't have major secrets, but I like my privacy.

I've been thinking for ages about moving to Linux. Most of what I need (internet, word processing, home accounts) is freely available. It also opens up possibilities for playing with some interesting new technologies. I just need to ensure that all my data can be transferred across. There's also the issue of using my peripherals. I just bought a Canon printer that is not officilly supported in Linux, but I found a comment on a forum that suggest it might work. See my del.icio.us links.
I will still have at least one Windows PC in the house if I really need to run Windows software. The kids use one for web and some old games.

I've got an old Celeron 433 PC that used to be in Dad's office. I had already upgraded it with my old Matrox video card, Yamaha sound card, more memory and a second hard drive, but had a problem fitting a CD. The case requires the drive to have plastic rails fitted and I couldn't find any that fitted. So I splashed out on a £10 case from ebuyer. It's not too bad actually, apart from having too many screws to undo. We have some old Gatemay machines at work that don't require a screwdriver to open the case and replace a drive. I guess something like that would cost a lot more. Over the last couple of evenings I've moved all the parts over and it all seems to work. I added a third drive in a removable caddy for backup and file transfer. Those three drives add up to less than 10GB. Not much by modern standards, but enough for what it will be used for.
Of course the PC will also be running the grid.org client to give me a few extra points, but it's going to take a while to process each work unit.
I know a lot of people think they need the latest/greatest PC, but unless you play new games it's over the top. Anything over 300MHz will be fine for internet, word processing etc as long as it has enough memory. 256MB should be a minimum. You can pick up old PCs at computer fairs for less than £50. Much better for the environment to re-use old hardware than to keep producing new stuff. Just keep back-ups in case the disk fails. If anyone has old hard drives that they have outgrown I might be interested.

Disable CD auto-run - The kids may have to find and click on something to play their games, but this 'feature' can be more trouble than it's worth. If nothing else it may stop you playing 'protected' music CDs on your PC. It's a bit technical this one as it involves the registry.
Get a firewall - The free Zonealarm software sits between you and the great wide internet, checking for naughty behaviour. The best option is to have it tell you each time a new program tries to access the internet. This should stop software installing itself and getting up to no good. It also makes you invisible to any nasty crackers (hackers are not bad people).
Install a virus checker - AVG is free and seems to do the job. Make sure you set it to get regular updates.
Don't use IE or Outlook Express - There are some very good products from Mozilla that let you surf the web and read your email without attracting every worm, virus or other bug that's out there. They also offer a lot more in the way of spam filtering and pop-up blocking.
Check for spyware - All sorts of apparently useful or fun software also installs other, less friendly, software that may monitor your surfing and bombard you with adverts. Ad-Aware detects and destroys most of these. Get it and run it often.
All the above are absolutely free, so there's no excuse.
