Gun control is political theatre, full of sound and fury, Signifying nothing.

Politicians on both sides of the issue energize their respective bases, rake in donations, and distract the public from more important issues.

Firearm and ammunition companies, and retailers rake in enormous sales. Perhaps some of this windfall makes it back into the pockets of those politicians who are most vocal about pushing for gun control?

I'm pretty sure nothing of legislative consequence will come out of this latest round of the gun debate. The big reason this is probably being pushed by the President is so that he can get concessions from Republicans on the fiscal issues. Then a gentleman's agreement gets worked out in a smoke filled room over copious amounts of scotch to where Obama lets the Republican mostly win the gun argument while Democrats mostly win this latest debt ceiling clash.  Hopefully this is all followed by people seeing Republicans rolling over on economic matters and then driving up the value of my bitcoins.

.Yes, the storage used on the Android is much less,  I found this posted on another web site:

"miners absolutely need the entire blockchain. Normal users need just the headers and those transactions that are linked to their addresses."

Is there a more detailed explanation around?

The reference client uses a full implementation of the Bitcoin protocol and works as a full node. To do this it uses the entire blockchain to store and relay transactions.

The Android app and Multibit use BitcoinJ as a backend and BitcoinJ only cares about addresses it holds in its wallet, so it doesn't need to have the whole blockchain on its own. Doing this though requires trusting those full nodes running the reference client.

If you have a computer that is on around the clock, like a desktop, laptop effectively used as a desktop, or a home server I recommend running a full client on it to help strengthen the network. If you have a lot of coins you want to keep on lockdown you can run the Armory client to manage that wallet, but Armory depends on having a full client running on the system it is on to provide it networking services.

Then for coins you want to just have on hand MultiBit or the Android Wallet are good solutions that provide you ready access to your coins. Electrum is another good lightweight client, but I have less experience running it.
1024  Bitcoin / Electrum / Re: Should I make a new portable version of Electrum? on: January 17, 2013, 10:20:36 PM
So, my question is, why create nonportable software in 2013 in the first place? Shouldn't all software be portable nowadays?


Sometimes, depending on what the software is you can look at as a user and think security risk. I agree portable software is useful for a lot of people and in a lot of applications, but there's still niches where some caution about moving an instance of an app from machine to machine needs some consideration.

We'd like to cover NCAA and tennis games, but for the moment we'll maintain our current selection plus the three leagues we're adding this weekend (NHL, Bundesliga, Africa Cup of Nations). We want to make sure that we don't miss any games from those leagues before adding more. Tennis in particular is problematic because games are played throughout the day and announced match start times usually aren't anywhere close to actual start times. We could probably do major tennis finals, semi- and quarterfinals but no promises on those yet. Also we're still looking into Asian handicaps for soccer.

We've been receiving more bets each day, so I want to thank those already betting with us and encourage more players to give us a try!

Have you though about an NCAA bracket pool?

It took a decent number of hours for the first bet I created to go through http://bitbet.us/bet/139/mlb-season-opener-rangers-over-astros/

It's nice to see a no account betting service with more meaningful outcomes to wager on than SatoshiDice. It's heartening to see such a full set of wagers on the NFL playoffs. Hopefully traffic grows and the Sportsbook beefs up these next few months. I can't wait to lose some money on the Alma Mater when College Football starts up again.

usual story, have ALOT of bitcoins with crypto xchange, and can not get them out.  Any suggestions?
are You talking about www cryptoxchange com ?
it looks for me as if they stopped the business on
19th Nov. 2012 and announced it on
27th Nov. 2012
You might like go in direct contact with them to get at least some of Your BTCs back.
Good luck

This, they joined the list of ex-exchanges.

I don't know how or why devcoin.org managed to point to bitcoinaddict, I thought maybe it was a godaddy parked domain side effect or something, as last night I tried to use godaddy's domain control systems to point devtome.org at devtome.com and also to point devcoinlorg there too. Maybe now it has propagated things will look different...

Hmm no, for me both still point at bitcoinaddict somehow.


If you updated the CNAME records it can take quite a while for that to propogate through the DNS system. You can hope it happens in minutes, but sometimes it takes hours or even more than a day. I had this problem when I moved the hosting for one of my personal sites to a VPS, changed the destination path in the GoDaddy panel. Finally a day an a half later I was able to access my new site using the domain name rather than through typing in the ip.

Hopefully by the middle of 2013 we will have:
+ encrypted wallets
+ HD wallets


This would be so great. I recently switched to Multibit for handling my wallet because last month Bitcoin-qt/Armory became too much for my laptop as the blockchain expanded. I still run full bitcoind on the home server to help the network, but the laptop travels a lot and the sync time was getting to be too much.

I love the Multibit interface with the MtGox values, keeping the last sent transaction details in the send tab, and the nice GTK+ theme. I miss my encrypted deterministic wallet though.

I have Ubuntu. But my system reboots every 6 hours and *always* corrupt my blockchain, forcing me download everything again Sad

But I'll try to use a VirtualBox with snapshots, so if I have the DB corrupt again I just recover the last snapshot. Anyway, OTC is complicated. For me, a 11-yrs programmers is annoying the steps, you can imagine for my mum, for example. It's true: OTC is impossible to handle. We have a more user-friendly system, maybe linked with Facebook account. I know it is possible to make FB fakes, but it's hard to do a good fake, with a lot of pics, old posts, real friends etc.
I used Electrum for signing. You are lucky GPG come pre-installed with Ubuntu but I don't think you will go that far. 

I don't use Facecrap btw.

Ditto on Facebook, not worth it.

Thats the issue. I'll have to figure it out.

I'd probably be interested, but shipping would probably be more than the trouble to ship the 1990 box, the 1991 set might be worth it though.
1032  Economy / Trading Discussion / Re: what is the ultimate system for Bitcoins reputation? on: January 17, 2013, 02:39:32 AM
But there is no web site where you can use a reputation system easily like "StackOverflow"-like-rep-schema, for example?

OTC is for nerds, and it's boring and useless even for nerds without time.

Atruk, really, do you think great mass will use something like OTC?  Huh

Maybe?

The alternative still involves spending a lot of time trading honestly and building up reputation that way.
1033  Economy / Trading Discussion / Re: what is the ultimate system for Bitcoins reputation? on: January 17, 2013, 01:21:36 AM
what is the ultimate system for Bitcoins reputation on the great mass? OTC does not count because it's complicated. TL; DL.

OTC is the gold standard. A close second is having your IRL identity well known. Beyond that the Rhodium circa 2008 (around 10,000 an once back then) standard is the strong WOT rating from OTC trades combined with a well known IRL identity.

For all of the effort it might seem to take to use OTC and WOT, as well as further time to build a reputation there that is where most of the big deals happen.

It is a bit much for most people, so a lesser standard is building up a general history of making good trades and not being and asshole. Read the scam accusations threads and understand why some things make people suspicious.
1034  Bitcoin / Mining speculation / Re: 253 BTC Bet that Butterfly Labs will Not Deliver an ASIC Prior to March 1st on: January 17, 2013, 01:11:31 AM
So the real question is, does anyone think that the rigs will be within the +/-10% specs of the bet?  Grin

Given the number of things  to go wrong in their latest delivery post, the chance they make that date and are within +/-10% of the advertised value rather than +/-10% of an FPGA's performance is probably slim.

I'll probably be in the market for some gently used FPGAs in the window between UPS tracking numbers going out and people firing up their butterfly boxes. If the BFL chips do outperform the FPGAs by the margin advertised, in the worst case I'll have an impressive collection of paperweights featuring Blinkenlights.
1035  Bitcoin / Development & Technical Discussion / Re: Why is it hard to track backwards from public address to private key? on: January 17, 2013, 12:58:17 AM
The one-way function is the basis of public-key cryptography generally. A simple example: take two extremely large primes p and q. Multiplying them yields a composite N but it is very difficult to derive p and q if given N.

From a mathematical non-super expert.

What you described is "large integer factorization" which is one method used in public private key cryptography but not the method used by Bitcoin.  It is the method used in RSA for example.  Eliptical curve cryptography used by Bitcoin uses a different method called "discrete logarithm problem" as outline by BurtW above.  The major advantage of ECC is that it is more efficient with key sizes.  256 bit ECC has roughly the same strength as 3072 bit RSA.

Still ECC can be somewhat difficult to grasp so large integer factorization is useful in the context as a generic problem which is easy to calculate but infeasible to reverse.   It is important to note that both RSA and ECC "work" because no efficient solution of the reverse has been found .... yet.  If someone were to discover a computationally efficient method of factoring massive numbers then RSA and other algorithms based on large integer factorization would fail.  Likewise if someone were to discover a computationally efficient method to solve discrete logarithms algorithms like ECC would fail.  This is different than finding a cryptographic flaw in a particular algorithm.

Essentially "large integer factorization" is based on the premise that it will remain exponentially more difficult to factor the product of primes and thus by chosing primes of sufficient size one can ensure the amount of work required to factor the product of those primes is beyond the capabilities of current technology.  Its strength comes from that premise and if it is flawed then all algorithms based on that premise will have no cryptographic strength.

And there's still one more step protecting an address's private key, because the address is a one way hash of the public key rather than the public key itself. As long as you never reuse addresses that you have sent coins out of, your public key will never be exposed. It is exposed when you send coins though, because it is included to validate the signature on the transaction from the private key.

#4 The chips work, but apparently we chose the wrong shipping option and the ASICs will be crossing the Pacific by boat. As the rest of the ship's cargo is especially heavy we estimate they will arrive in dock thirty days from now.

Hi my Mom has a new real estate company called "Gold Keys Realty" and she needs a logo

Post a logo and ill ship 6 bitcoins to whoever creates the sharpest one thanks

10 posts, offering 6 BTC = any proof you have them and will actualy pay for logo? Unless you can provide some, I'll skip your deal, sorry.

This problem could be solved if this request was posted to a site that served as an escrow service like http://www.rugatu.com/

I've had success these past two weeks with hundred dollar moneypaks. The first took 12 confirmations because I sent it through the Blockchain.info anonymizer without using a blockchain.info wallet. The second I sent from my client and it appeared in 6 confirmations. I just keep my browser open to the page where I made the transaction and write down the transaction code immediately. My most recent transaction with them was yesterday morning.
