Hi Casascius, how will we be able to get private and public keys onto the hologram? Is that going to require that we have our own laser-engraving equipment?


(the sticker will be TRANSPARENT where the lettering is - so for example, if "..." - three periods - are lasered, that will be rendered as three see-thru dots on the sticker itself where there is no foil.)  This laser etching is done during production and affects only the foil - the plastic is intact over the lettering.

It looks like if you had your own laser etcher that matched what the printing company does (and if it can be done to the final product and not exclusively as a mid-production step), you would be making the area transparent, not printing on it. Not good for private keys.

2563  Bitcoin / Bitcoin Discussion / Type Bitcoin symbol ฿ with your keyboard! (Windows - US Keyboards) on: January 18, 2012, 08:03:39 PM
I've created a new keyboard layout for Windows (Win2000-Win7) with the Microsoft Keyboard Layout Creator (link in case you want to do it yourself). This is the standard US keyboard layout, except when you press CTRL or RIGHT-ALT, you get some new options:



We know Shift+4 is the dollar sign; now CTRL+4 or RightAlt+4 gets you ฿! CTRL+NumPad "." is also ฿ (some programs like Firefox reserve CTRL+Numbers). In addition, the other currency symbols are available as shown above.

Download:
http://we.lovebitco.in/us+btcKB.zip - installer for all platforms (unzip to it's own directory) (253k)



Install:
1. Simply run the setup.exe after unzipping, you'll get a success message when it is done:


2. In the Control Panel, Choose "Region and Language" (Vista and Win7, shown) or "Regional and Language Options" (WinXP). Press "Change Keyboards" on the "Keyboards and Languages" tab (Vista and Win7), or "Details" on the "Languages" tab (XP):


3. In the "Default Input Language" dropdown list, you will have a new option! Select it and press "OK".


4. You are now ready to type ฿! You do not need to restart Windows, but any applications will need to be re-opened for your new keyboard combos to work.


PS. You should never download and install programs on your computer with Bitcoin, but you can trust me, really!

It appears that "minimize on close" and "minimize to tray instead of taskbar" options don't work correctly on Win32 (Windows 7 x32). I've tested checking the options and restarting too.

-Bitcoin appears in both the tray AND the taskbar, both when operating and when minimized and regardless of the option "minimize to tray".
-"minimize on close" works, but it doesn't care about the other "minimize" option, it closes to a tray icon regardless, the option works like "tray icon on close", not a "minimize on close".

well, we will see, I just bot 4 cards yesterday Smiley

I would have purchased them manually.... Tongue

$2000 of the most expensive mining cards at a high difficulty = a loooong position.

2568  Bitcoin / Mining support / Re: 3 BTC Bounty: help me diagnose my mining rig lockups and reject rate on: January 18, 2012, 07:17:20 AM
@deepceleron: you nailed it with upgrading to phoenix 1.7.3 for lowering my reject rate.  Been running all day, reject rate is now at .134%!  I guess phoenix 1.7.0 had issues with rejected shares?

I lowered my core clock from 780mhz to 720mhz; 700mhz is stock for 5970's.  This lowered my hashrate by 100 MHash (not a big deal).  I still had a couple of lockups today though.  I'll bring it down to 700mhz tomorrow.

As of now at least 1.5 btc of the bounty is going to deepceleron, probably the remaining 1.5 btc too if there are no more suggestions.

That was a bugfix that was rolled out, I didn't find a definitive post that stated "this fixes all your stales" in the Phoenix thread for you, but it no longer lags for .5 seconds, and it also supports rollntime so your miner doesn't have to request more work if it completes a nonce space (supported on some pools).

The one card that is running significantly hotter - you could pull it and make sure it has well-applied thermal grease. It should only have a very thin coating on components (not blobs squeezed out), and can benefit from an upgraded thermal paste like arctic silver 5. Clean the old stuff with 99% rubbing alcohol (or Everclear), and re-apply a paper thin coat of new TIM on the chips. Put the heatsink on with the normal screws and take it back off again. You should see from the thermal paste impression on the heatsink that there is good contact being made.

If you still lock up that close to core clock on the cards, I would remove one card at a time (maybe starting with that hot one), and and put your miner back to overclocked. Run the card you removed by itself mining in it's own computer (your desktop computer or a $50 Craigslist dell) and see if the problem follows one card.

So even with the latest hit on bitcointalk.org wallet stealing incident "bill cosby", my defense+ would have not stopped my wallet getting taken?

Win7 64bit.

There were no wallets stolen or anything bad. The jokers used a flaw in an old version of the bulletin board software to put a javascript on the site that displayed a bunch of cosby animations and graphics, nothing else.

oclvanitygen -d 0 1Bitcoinz    (0 = device # and the string is the address searching for 1Bitcoinz is impossibly long which prevent the generator from getting lucky too soon)


<--- not impossibly long...

Another thing if you are running oclvanitygen, it will benefit from memory as overclocked as you can go.
2571  Bitcoin / Mining support / Re: 3 BTC Bounty: help me diagnose my mining rig lockups and reject rate on: January 17, 2012, 09:46:54 AM
Upgrade to phoenix 1.7.3, you'll see reject rate drop quickly. You could also switch to a pool with known low rejects that doesn't charge the highest fees in the pool biz (which is good for another 3%-10% "boost" to your bottom line).

Not what you want to hear, but I would run the cards closer to stock speed and then if it still locks up, overclock at least is eliminated as a cause of your problem. Pushing a card too hard would get me a random reboot every few days.

Here's one that I made myself, donations if you feel like it. It's a midi file which most phones use (and they sound more ringtoney too).


Inspired by a classic C64 video game, you can probably figure it out.

There's been a fair bit of commentary on the lack of interest from the housewives who make up the majority of the show's audience.

If it had a different name, like "Elite Women Lawyers of Chicago", maybe we wouldn't expect it to be about a church-going cupcake-baking house frau, and it might get more than housewife viewers... Like "House", it is not about a house at all. It should be called "Asshole Genius Doctor Always Gets The Fourth Diagnosis Correct".

2575  Economy / Trading Discussion / Re: Mt Gox - withdraw Address changed, Bitcoins Lost? on: January 16, 2012, 08:47:59 PM
To clarify: The "My Bitcoin Address" shown to you in the Bitcoin client often changes. This is to enhance anonymity, so people can't easily examine what kind of payments you have received. If you only had one address, it would be possible for others to see everything you've been doing with Bitcoin by knowing your address. You have multiple Bitcoin addresses, all of which are forever valid, even though only one is shown in the main window.

Any address you get from your Bitcoin client is always going to be good. You can re-use the same address when requesting a payment from MtGox so it is easy to keep track of the payments from MtGox, or you can use different addresses so that it is harder for others to discover payments to you and your actual balance.
2576  Other / Beginners & Help / Re: If someone sends me some BTC how long should it take to "arrive"? on: January 16, 2012, 08:35:52 PM
If you have your Bitcoin client open at the same time the transaction is sent, you should immediately see that someone has sent you money. However, in order for the payment to be processed, the transaction needs to be included in the Bitcoin blockchain, which can be a few minutes to a half hour. Waiting several more Bitcoin blocks after the one that contains your payment ensures that the payment to you will be a permanent addition to the blockchain, and the Bitcoin client considers six more blocks (about an hour) as when the payment to you is "confirmed". Your Bitcoin client also needs to have downloaded all transaction blocks including the one with your payment to see these confirmations.

More screenshots:

4. Receive Coins screen:


5. Transactions screen. The tooltip is from hovering over the last entry:


6. Address Book screen. You can't send from here, but you can create a new address and label existing addresses:


2578  Bitcoin / Development & Technical Discussion / Bitcoin 0.5.2 screenshots on: January 16, 2012, 08:03:36 PM
Screenshots of 0.5.2:

1. Overview screen - first view when starting Bitcoin (tooltip is from hovering over the last "recent transaction"):


2. Send Coins screen. Next to the address field, the first icon is Choose address from address book. The next icon is Paste address from clipboard. The last icon is Remove this recipient (enabled if you have added several Pay To recipient entries):


3. What we see after clicking the Choose address from address book icon:





2579  Bitcoin / Development & Technical Discussion / Re: Bitcoin 0.5.x and it's major interface update on: January 16, 2012, 07:31:32 PM
Also one other thing I've noticed, I don't know about you or others, Comodo Defense+ said that bitcoin-qt needed to access something of the system component which gives bitcoin-qt.exe access to take screenshots of your desktop.
"Accessing the screen directly allows an application to draw custom bitmaps"; there's your answer. In order to avoid this security warning, likely all graphics and button icons would have to be removed from the program, or a windows-only client using only the windows API to create the GUI would be needed.

I just installed 0.5.2beta for my first look at 0.5.x-qt, (been letting others test the bleeding edge...), and didn't realize before how much the interface was changed, and I am impressed with the layout of information. It is basically how I would have designed it.

Some things are annoying, like hiding the block count, confirmations, and connections behind icons. Fees could be shown in the transaction window, and the block number in the transaction details. Address book is sparse; it doesn't clearly state that these are others' addresses you have previously used to send people money, doesn't let you do anything like send coins to an address you choose, and could be integrated into "send coins" better - The "address book" menu bar icon changes the whole interface to that "tab", but finding and pressing the unlabeled "address book" icon in "send coins" brings up a different but identical address book window. The "Export" icon is not consistent with UI user expectation; it functions to export data from the other icon you have selected, it is not it's own "tab".

Beware deepceleron's razor: when you make something so simple even idiots can use it, only idiots will use it.
