How to get Armory to use Bitcoin-Qt's block chain on OSX ...

Are we overlooking pgp verification of wallet installation files?

I am curious how many people use pgp to verify the new version of their favorite wallet software every time a new version comes out? To me it seems like pgp verification isn't taken very seriously. Most, but not all vendors will put out new pgp signature files with each new release however if you are relatively unaware of security this could mean you are unknowingly missing a very important step. Importing the authors pgp key, downloading the associated signature file and then verifying the executable isn't very obvious to those who aren't security savvy. However it is an obvious security hole and a potential honeypot for anyone looking for some easy coin. One thing I find disturbing is how few of the major wallet developers put any significant effort into educating their users on the first step of securing their hot wallet. Multibit and armory are the only two clients I know of that give any information on pgp verification, but even multibit misses this important step on their "How to install" page. Electrum doesn't even provide a signature file for their linux version instead providing a hyperlink with an md5 hash appended to it. Bitcoin-qt from what I can tell only provides sha256 hashes of their files with zero instruction on how to use them. To me it seems like the pgp step of securing a wallet is looked at as the boring minor tidbit that you have to have that nobody really wants to put time into resulting in most vendors throwing up some hashes/signatures with little to no information on how to use them. I think that all vendors should have a section with instructions on how to verify their software, put this as the second step in getting started with their software right after the download step and make sure to provide pgp signatures for each installer package and not just hashes. For me, not being a security expert, I feel much safer verifying a pgp signature vs checking that a hash matches. With bitcoins being targeted on a daily basis through incredibly creative means this seems to me like a giant gaping hole that could be fought with a very small amount of education. Just a thought.
Edit: because I suck at the grammar Edit: after digging around I found the electrum signature files for linux. There is no direct link to the page from their website but they can be found here:

If bitcoins became a real player in the world currency, wouldn't the blockchains be ridiculously large?

I am trying to decide which is better for me, electrum vs. armory. With my limited knowledge, it appears that armory requires a local blockchain vs. electrum, which uses's servers. Satoshidice doesn't really help that much either.
If in, say, 5 years.. the blockchain has grown astronomically... wouldn't it be a pain to maintain a local blockchain? If i reformat my computer, for example, it would likely take days to fully re-download and re-verify. If my bitcoin QT client goes down, how would I go about recovering my coins? and if electrum's blockchain went down, how would i go about recovering my coins?

A call to all streamers: use bitcoin!

(Cross-posting from TL)
All you need is to overlay something like this qr code to your stream, and that's it! Now anyone in the world that sees it and holds some bitcoin, can donate some to you.
As far as I know, the options we currently have to donate some money in support to our favourite players are restricted to two: to subscribe to their twitch channel, or to donate using paypal. While these modes of payment might suit some, I feel that streamers are loosing on a potential source of income by not enabling bitcoin donations. Its quite easy to set up, and it has zero costs.
Awesome! How do I do it?
Now it's trivial for anyone in the world holding bitcoin to send you some. They just need to scan the qr code or copy the written address, and use it to send from their wallet.
Bitcoin can also be as easily used in a tournament setting. For instance, in TotalBiscuit's Shoutcraft America series, he set up a tip jar paypal account for every contestant, so that people could send tips to their favourite players. I thought that was a brilliant idea, but felt that the lack of a bitcoin option was a missed opportunity. Would have been as easy as to embed the 2 player qr codes at each side of the hud during each match for anyone to instantly be able to tip the players.
In other news, TotalBiscuit announced at the end of his last Shoutcraft America tournament that he'll be hosting a bo7 showmatch between NaNiwa and Scarlett, for the price of 12 bitcoin. I have already seen talk of people wanting to add their own bitcoins to that prizepool (as if it is not high enough!) as soon as he makes the price address public. And I think having the ability to do so is awesome!
Some more examples of qr awesomeness
Stuff you should also probably read
Wallet security is an important topic. The money people send to the receiving address can be spent by anyone knowing the private key that generated the wallet. This means that yes, online wallet providers can theoretically rob you of all your coins. The blockchain wallet is considered to be the safest of the online wallets, since it hands you the private keys and allows for two factor authentication wallet management, but the safest option is still an offline private wallet. Personally I like Electrum, but you can also use Armory or the bitcoin-qt original client. TL;DR: use online wallets for pocket change, and store any meaningful balance cautiously.
Also it's worth noting that anyone that knows your receiving address can see your live balance (for instance you can see the current balance and all past transactions of the wallet I just created for this post here ); another reason in favour of moving your funds around if they get meaningful.
But wait a second... What is this bitcoin thing you're talking about?? Is it edible?
Nope, but you can apparently buy pizza with it! I'm sure most of you have already heard about it, with the current price bubble news, the announcement that Team Liquid is now accepting bitcoin for the store and TL+ subscriptions, or if you have seen the bitcontip bot in action in some subreddits. However bitcoin is a pretty complex topic and there is a good amount of misinformation floating around, so if you want to learn the facts you can watch this video or visit these webpages or the bitcoin wiki.
Are you a cyberpunk cryptoanarchist neoliberal technocapitalist nerd new world order reptilian illuminati conspiracy-theorist drug dealer anonymous and freemason member?
Yes! And on top of that I also am an avid SC2 fan and a bitcoin enthusiast. And I think esports could greatly benefit from bitcoin, and that bitcoin could greatly benefit from esports; they are made one for the other. This is my attempt at playing matchmaker!
Disclamer: Please use this post to discuss the involvement of bitcoin within the SC2 and esports community. To discuss about fundamental bitcoin issues, please use head to bitcoin. Thanks.
