Any word on a bitcoin specific live cd/usb distro of linux as mentioned at the end of the article?  That'd be rad!  Also, what live OS do y'all prefer?  Deciding between Tails and Liberte, but I'm open to suggestions.

Thanks for the advice.

Perhaps the OP could add screen shots to guide newbies like us? "A picture tells a thousand words"

I always wondered something like that too.  Where if someone steals you wallet does changing the password on my wallet make it secure or the does the person who stole it have the copy of my wallet with the weaker password. In that case would I just consider those bitcoin addresses and keys compromised an just make a new wallet and transfer the bitcoins out of those compromised address to a new secure bitcoin address that hasn't been compromised before the password is cracked?

zero3112 you should use as secure password as possible even on your copy.
what if someone steels your copy ?
if you choose a secure password most chances that you are safe even if someone will steal your wallet (as long as he haven't been able to steal your password)
the thing is that you might wont even be aware someone stole your wallet until its too late so the most secure method is to use a paper wallet you know can't be stolen unless someone breaks into your house.

Does wallet.dat ever change?  If the encryption bitcoin uses ever gets cracked (say some method of quickly reversing the hash), wouldn't the encryption need to change?  In that case, wouldn't you need to recreate your wallet.dat?

junbin - the wallet might change if you send coins out of it. you can read more about it here -
https://en.bitcoin.it/wiki/Change
In short is some transactions require your client to generate a new address fo you to get change in.
by default I think bitcoion-qt generate 100 addresses for the wallet. so after 100 transactions you might need to backup your
wallet again (but don't catch me on the word here I guess its best to backup whenever you can if your sending coins)
if you only receiving coins it shouldn't be an issue

Any word on a bitcoin specific live cd/usb distro of linux as mentioned at the end of the article?  That'd be rad!  Also, what live OS do y'all prefer?  Deciding between Tails and Liberte, but I'm open to suggestions.

I created a small an ubuntu based live cd with the most common bitcoin tools already in it.
you can download it from my blog -
http://blog.non.co.il/index.php/bitbuntu-livecd/
But you might want to wait a bit since I'm adding more tools to it and I hope to release an updated version in a few days

This is somewhat related to a secure wallet-- Is it safer to keep your bitcoins at mtgox or to put them into your wallet? What i want to know, is should I get my bitcoins out and into a wallet right away?

This is somewhat related to a secure wallet-- Is it safer to keep your bitcoins at mtgox or to put them into your wallet? What i want to know, is should I get my bitcoins out and into a wallet right away?

In theory its safer to save your coins in your own wallet, and paper wallet is considered the most secure way of doing so.
so if your not planning on trading your coins too often its better to take them out of gox.

Yet I wouldn't rush to get all my coins out of gox If i still want to trade. Gox have been hacked once and I think they will do their best to prevent a second incident.
also they compensated all the victims of the first attack for the amount that was stolen so if your account does get hacked and its not your fault (its not somebody who guessed your password because
you chose a week one or hacked your pc and got your gox credentials) and you can prove it (which probably mean it will happen to many accounts and not just one) you might get compensation from mt gox.
which is some thing you will never get if someone manage to takes coins from your private address.
I don't want to be to clear about a compensation from gox since I have no connection to gox and I can't talk on their behalf, but in the end they have an interest of keeping their clients trust even if someone will hack theme.
