I love the new layout. And I especially like seeing Multibit first on the client list. I remember first trying the "default" client only to get very frustrated, but when I later tried out MultiBit it was smooth sailing.

Multibit will complain on most newbie machines that "No Java found". Which is tedious presumptive and dangerous to install too. So it's not quite recommendable for beginners either.

I fixed the quoted text for you. There was a new Java release 10 days ago fixing critical security holes, and already there is another vulnerability disclosed. When that's patched, the next one will be used...

"Foundation" and "get started" are links to other sites, but they appear equal in the site hierarchy to sub-categories. Main-menu style links should be consistent and not launch another web site without the destination being apparent.

I will take on "en/how-it-works.html". I was just going to fix the fragment sentences and the sentences that start with a conjunction, but upon reading the content, it really could be better, so a refactorization is in order. This is the first stopping point for a new user - they will have no concept of what this new "network money" is, where it is stored, or how it can be uncounterfeitable. The illustration is non-illustrative.

I do not require that everyone use GPG; rather, it is mostly used to verify that the addresses I issue come from me and not another impostor. I can hold escrow for such transactions (and I've done a couple of those too), but please remember that I only hold BTC in each transaction. The system would work like this:

1) I receive the amount agreed to at an escrow address.

2) Buyer sends the PayPal transaction.

3a) Seller confirms, escrow released.

3b) Buyer denies receiving of the funds; I instruct either side to change to a temporary password and grant me temporary access to the account to verify the transactions involved. Alternately, screenshots may be provided in the first place as a weaker evidence. Funds released to whichever side that convinces me the most based on hard evidence.

you forgot step 4: buyer charges back PayPal after receiving their purchase and gets their money back. PayPal is bad, mKay...

please remember that I only hold BTC in each transaction.

This puts the escrow agent in a harder position - did the seller send a box of rocks or is the buyer lying? Did the item get stolen off a porch when it was delivered? Since money-only escrow is to ensure the potential-scam seller doesn't get undisputable Bitcoins until the purchased item is received, it still leaves open the possibility of claims from an unscrupulous buyer that they didn't get the purchased items, either to get a refund or to just deny payment, or for the seller to ship a box-o-crap and claim the buyer is lying about getting crap.

Here's something I typed up previously describing full escrow, where the escrow agent only forwards on the transaction after seeing both the payment and the item are legit:

Consider these escrow conditions, these would be mine:

1. Bitcoins come first; you won't be sending a package until I confirm payment is secure. The payment address wallet/keys will be backed up the wazoo, with a paper copy of the address keys and transaction info for my next of kin to discover.

2. escrow agent -> buyer shipping cost comes out of the Bitcoins, I'll calculate for you pessimistically @ today's MtGox if I know the box weight, dimensions, and destination ZIP.

3. The singles (or any other item) must be shipped to me with signature service so you can prove to yourself I got them (this based on my experience of eBaying hundreds of items, this is to prevent shipping services leaving stealable packages at the door instead of hand-delivering to a person, or marking them "delivered" when nothing was delivered, it was delivered to the wrong address, or it was stolen by the delivery driver). The items must be double-boxed, over-packaged, and well padded, so it arrives safely and so I don't have to re-box it to meet insurance requirements.

4. If the package is lost or damaged getting to me, you must have insured the parcel yourself and claim the loss yourself. I will refund the Bitcoins if I do not receive the package or if the package contents are not as described or damaged (after waiting around a month to ensure the package was not misplaced or delayed in shipping).

5. I will re-ship FedEx insured with adult signature confirmation to a physical address only. No post-office box services either (I will Google, seller should check address also).

6. Carrier signature-proof-of-delivery will be proof I completed escrow service. When it is delivered with signature, the transaction will be final and I will send Bitcoins. There will be no claims the package wasn't received if it was delivered and signed for.

7. If the package is lost getting from me to the buyer, I will pay out the Bitcoins to the seller after a similar waiting period to be sure it's lost for good and that the shipper acknowledges the loss and insurance will cover it. I will compensate TO THE BUYER only what I am able to get from insurance (all shipping companies have insurance adjusters that are dicks and routinely deny claims you have to then appeal, will only pay "replacement cost" regardless how much insurance you buy, etc).

8. If the package is damaged getting from me to the buyer, I will compensate TO THE BUYER what insurance pays out (see above) as a replacement or repair settlement. Buyer must cooperate with insurance adjuster's package inspections and/or pick-up of damaged packaging and any or all shipped merchandise, etc.

I think I've thought out every escrow scenario here. Anyone considering doing escrow services should examine the above too, so a buyer and seller know the score when it all goes wrong. 6, 7, and 8 seem like the best terms for fairness and to protect seller and escrow agent against unscrupulous buyer claims.

That was generous of you, not many would have done that. IMO that wouldn't be wrong but still a good gesture on your part.

Yes, especially since if you didn't loan the BTC, you would still have the full amount plus zero risk of default. Of course 2.5 BTC of interest just became more USD profit.

1530  Other / Beginners & Help / Re: Sending BitCoins without Transaction Fees! on: March 02, 2013, 09:34:18 AM
The age of the coins and the amount you are sending will determine whether you can send for free. Sending without the minimum fee when it is required will cause you headaches later, and the Bitcoin client won't let you do it.

First, recognize that a transaction is made of:
- inputs - the funding source(s), the individual payments you previously received, and
- outputs - the amount(s) you are sending to different addresses. Typically only one or two outputs, but you can send to many people in one transaction if you want.

The baseline calculation for "when it becomes free" is 1 BTC after one day. If the input of your transaction is a single 1 BTC payment you received over a day ago (144 confirmations), then Bitcoin-qt won't require a fee, even if you are only sending .1 BTC to someone else (the other .9 is also sent, but it's sent back to your wallet as another output). Likewise, if your balance is from a single 0.1 BTC, a transaction using that payment would be free to send after 10 days of confirmations.

The above examples are when your transaction is made of one input. Often a transaction will be made of many smaller previous payments to you, put together by Bitcoin in whatever way it calculates will minimize the change that needs to be sent back to you. Therefore, it can be harder to know if you will need a fee without actually attempting to send the transaction. No "warning, requires a fee" message? That means a fee was not required, and only your optional fee (if set above 0) will be included.

If any output of your transaction is less than 0.01 BTC, a minimum fee is required regardless, to keep people from cheaply spamming the blockchain by sending the same money over and over.

In 1985 the Cray-2 supercomputer was released, and was the fastest computer in the world for five years. It cost about $16 million in 1985 dollars. The memory was 256M 64k words, more than all previously produced Cray-1s combined - 2GB.  It had 1.9GFLOPS of processing power in it's fastest configuration - approximately equal to an iPad 2, and significantly less than the computer I'm typing on.

I think that technology might keep up with Bitcoin.

Big Hint #2 - The answer wouldn't be different if I used lower case letters instead of upper case, but the clue would only be one letter!

Would you care to explain the above for me, for I read it as if all the letters were put in lower case, the solution would be easier to solve, hence putting all the letters in lower case to visualize a solution.

Now, if you had said: The answer would be more difficult if I used lower case letters...

Then we all would have continue the quest staring at upper case letters.

Imagine the problem uses a magic black box that only outputs letters of a certain criteria:

letters ----->[MAGIC BOX]----> only letters that match criteria

So to make the puzzle, we put two sequences of inputs into the box:
letters A-R:  ----->[MAGIC BOX]----> clue sequence
letters S-Z:  ----->[MAGIC BOX]----> rest of sequence

When the criteria is "typography of letter includes a diagonal line", the outputs are:
letters A-R:  ----->[contains diagonal?]----> clue:{A,K,M,N,R}
letters S-Z:  ----->[contains diagonal?]----> answer:{V,W,X,Y,Z}


If the puzzle was created with lower-case letters however:
letters a-r:  ----->[contains diagonal?]----> clue:{k}
letters s-z:  ----->[contains diagonal?]----> answer:{v,w,x,y,z}


Using lower-case letters, it would be impossible to make a puzzle with the criteria "contains diagonal" that had
 A. a good enough unique answer, i.e., if I asked you to "complete the sequence {z,y,x,w,v}", how would you know the answer is {k}? or
 B. a non-obvious answer ("complete the sequence {k,v,w,x,y}")

That's right! You get the genius award! I considered VWXYZ to be the answer, but had noted VWXY would also be a correct answer based on the information available.

I call foul and should be rewarded the prize. BTW, what was the prize?  Roll Eyes


You get a critique of your signature, which says BTC = $c2. Assuming that $ is a place holder for an input value of X dollars, than the units of your answer would be:

bitcoins = X * 89875517873681764 dollars*meters2*seconds-2

I guess I didn't realize that dollars stored kinetic energy...

AKMNRVWXYZ

everything that has something diagonal in it... it had to be something with the shapes because capitalization changed things.

I'm not sure about Z, could be only \ are trigger shapes, but not /. Z is the only one that doesn't have a \

The official bitcoin-0.8.0-linux.tar.gz has a directory structure to the archive. From the directory where you extracted it, you can run Bitcoin by typing ./bitcoin-0.8.0-linux/bin/32/bitcoin-qt & in a terminal.

You can also move the above bitcoin-qt file to another directory by itself, no other files from the archive are needed to run Bitcoin. You can be really fancy and add an icon for it.

Make sure that you successfully created a persistent directory for your data, that you can shut down and reboot and your Bitcoin wallet addresses and the current block count are still there (just booting the live cd will always forget anything you downloaded as it only uses a RAM disk.) Also use UUID, so that partitions will always be found even if you use different USB ports or a different computer:

http://wiki.tinycorelinux.net/wiki:persistent_home

now that MSFT appears to be preventing booting from USB sticks in Windows 8, will your TinyCore USB system still work on those machines?
Newer machines may use UEFI boot instead of BIOS, this requires a 64 bit distro and UEFI bootloader (Ubuntu 12.10 64 bit is one distro that is ready, tinycore liveCD is not). This is not "Microsoft preventing booting", it is pretty standard for it to be enabled on new PCs now that Win8 supports it; old BIOS doesn't support hard drives larger than 2 TB. Macs also use EFI. Only incompetent hardware manufacturers have a problem.

If "trusted boot" is enabled, a computer will only boot signed code. This is being worked on by kernel devs, but it requires kernel code signed by Microsoft. This is more of a grab by Microsoft that no user wants, under the guise of more security.

Both of these "features" can generally be disabled in BIOS. Windows 8 certified systems are required to permit the user to disable Secure Boot.
