Seriously how much work do you think you are going to get for 75 BTC at a proper "software house" (at the rates I normally charge you would get less than 40 hours for that amount - and although I am very competent I don't believe that I could possibly complete all those tasks in that amount of time)?

And if you think it should be outsourced to some even less skilled people (like many on freelancer.com) then I think your chances of even getting a working solution are remote.

Also in regards to inexperience I am happy to help out with any C++ questions from either contributor (and I have been writing C++ professionally since the mid-90's).

One further thing to understand is that FellowTraveller can "Reject" the tasks being currently performed by any contributor (on the grounds that they are overdue) - yet I think he understands that if he did that now then NO-ONE will do them (as I wrote before - Xenland and JaSK are the only two to even bid on *any* of the Moneychanger tasks on CIYAM Open).

Faith in "electronic postage stamps"?

I must say that I am not surprised (all along Open Coin had stated that the purpose of XRP was not to be a currency itself - but at the same time they profited greatly by not intervening as the gullible bet on it).

They are clever at "social manipulation" but I think they will find that people don't actually enjoy be tricked (especially people that have ended up losing money because of it).

I am in the process of putting up some very simple tasks for the CIYAM project on CIYAM Open (some of which require a little programming skill and some none at all).

For example: https://ciyam.org/openid/open/?cmd=view&data=20130731083804662000&ident=M100V131&chksum=a774e4db

I've yet to allocate BTC to these tasks yet (am still looking at other basic "house-keeping" things I'd like done for the project and will add those as well then finalise a budget).

So if interested you might be able to pick up some BTC through one or more such tasks.

Indeed - only *two* people have even put in bids to do any of the tasks and of course those bids were created by the *only* two people that are working on any of the tasks listed on CIYAM Open.

So if you think that they shouldn't be working on the tasks then there would be ZERO people working on them instead.

In the standard client there is no way to do this (although you can use the Coin Control patch to do so*).

The software automatically chooses UTXOs and creates a "change address" for you if they do not equal the exact amount you are sending.

So let's say you have 3 UTXO's as follows:

1Addr1 0.2
1Addr2 0.2
1Addr1 0.2

and you want to send 0.3 to 1DestAddr then it will use two of the three UTXO's (which could be both 1Addr1 ones or one 1Addr1 and 1Addr2 one) then create a new address (1Addr3 let's say) to send the 0.1 change back to yourself.

*Note that if it choose to pick 1Addr1 and 1Addr2 UTXO's then there are *two* so called "from" addresses (i.e. the balance of an address is actually just the total of all UTXOs for it).

Sure - CIYAM Open's topic is here: https://bitcointalk.org/index.php?topic=132006.0 and also welcome to PM me with questions or more details.

In regards to making money eventually new Projects will require a fee to list but as a way to get the concept (and of course the website) promoted I am providing free listings for the first 10 projects.

Yup - I guess the OP doesn't understand Bitcoin very well - time for me to leave this topic...

Haha - your large merchant mines then do they (if not then why would they want a less secure network)?

As mentioned in the other topic (https://bitcointalk.org/index.php?topic=265488.msg2874428#msg2874428) CIYAM Open would be happy to host the project task management free of charge (as we are doing for Moneychanger - https://ciyam.org/open/?cmd=view&data=20130606055250338000&ident=M100V137&chksum=a2a9d6d5).

If the OP is interested then I would be happy to create a project on CIYAM Open for this (subject to *zero* fees).

CIYAM Open is a project management system that unlike traditional "bounties" (where multiple contributors compete for a reward that only one will get) locks in a single contributor to finishing the task by an agreed date and time (with a merged git commit being generally used as "proof of delivery").

The system is currently being used to help manage the Moneychanger project (https://ciyam.org/open/?cmd=view&data=20130606055250338000&ident=M100V137&chksum=a2a9d6d5) and note that all BTC is held by the project's owner (i.e. no actual BTC is held on CIYAM Open and each project manager provides their own BTC addresses).

An introductory slideshow about the workflow can be found at http://ciyam.org.

That just looks as though you didn't pass a correct (or any) password to MySQL.

So the election has finally been announced and I've thought of an idea to solve these two big problems.

1) The NBN under Labor will be "fiber to the home" (something that would serve Australia very well in the future) but under Liberal will only end up being "fiber to the node" (nowhere near as good but of course much cheaper).

2) Both parties want to stop the "boat people" (despite the fact that tens of thousands of people arrive by plane and stay in Australia illegally due to overstaying their visas - but whatever as a nation we seem to *hate* boat people).

So why not have a policy that says: Provided you are not discovered to be some criminal that should be sent back to where you came from you can *earn* your Australian citizenship by working on the NBN rollout for 1 year?

If you look at the past you'll see that huge projects such as the Snowy hydro project and even the Great Ocean road project were basically done this way in the past.

This would greatly reduce the cost of constructing the NBN and at the same time provide a place for new immigrants as has occurred in Australia's history (and no-one these days complains about immigrants who helped with those earlier projects).

I think that if you don't already know how to code the use of a pool of unused addresses then you would find it much easier to use an API as some of the other responders have mentioned (just make sure that the key used for the API call to generate an address is not the same one for being able to spend BTC).

Yup - pretty much what I said - I think whether you would use bitaddress or vanitygen probably comes down to just how many addresses you want to generate (under 1000 probably bitaddress is easiest but over 10,000 and I think vanitygen would be better - it would also depend upon what sort of tools the OP is comfortable working with).

BTW - QR codes can easily be generated in javascript (so that shouldn't be your major concern either way) - code to do so is in both bitaddress.org and brainwallet.org (and probably plenty of other websites).

If you are not the owner of the server and can't be 100% of its security then you would not want to be generating key pairs on it and even APIs are going to be problematic in regards to keeping your "API keys" safe (although I think many APIs might have different keys for creating addresses vs. spending BTC so you should be fairly safe with those).

Another approach might be to generate 1000's of keypairs (or more depending upon the expected frequency of usage) from an offline computer using bitcoind or vanitygen and then import just the "public" keys of the key pairs into a DB (as a public key pool).

When the pool gets near to running out you would just replenish with more.

CIYAM Open now supports Google Authenticator 2FA

Now before you go all anti-Google please understand that the Authenticator is actually an implementation of the RFC 6238 TOTP algorithm (and does not involve even accessing google.com).

Although the actual Google version of the Android app wants Network permission (to periodically update the clock) it is not necessary for it to do so and so if you prefer you can use a version that requires no special permissions from CIYAM here:

http://ciyam.org/Google_Authenticator.apk

Source code for this version of Google Authenticator can be found here:

https://github.com/kactech/otp-authenticator-android

To set up your account for 2FA do the following:

1) Download and install Google Authenticator on your Android device.

2) Log in to CIYAM Open as you normally do from your PC.

3) Click on your user name (near where the Logout link is).

4) Click on the little window blind cord icon to "show more" details (yes got to get a better pair of icons for that).

5) Click Edit Details and then click on the Use Authentication checkbox (now a QR code that contains the Google Authenticator URI should appear).

6) In your Android device start the Google Authenticator app select the Add Account menu item (if it doesn't do that part for you automatically).

7) Click the "Scan barcode" button and then scan the QR code from your PC screen (if that doesn't work for you then the account will have to be added manually - the "secret" key is shown below the QR code and PIN fields for that purpose).

Type in the 6 digit PIN that the Google Authenticator app displays (you may need to make sure your clock has been updated to network time recently if it doesn't match the expected value).

9) Hit Enter or click on Save Details (and don't worry without the correct PIN it will not allow the record to be saved).

10) To test Logout then Login (you should be prompted to enter the PIN after the initial password login).

The 2FA implementation is applicable to all types of CIYAM Open accounts (i.e. standard, OpenID or GPG) and to switch it off repeat steps 3 to 5 (this time "unchecking" Use Authentication) and Save Details.

There is a way to make money out of extraordinarily cheap housing but actually it does require quite a bit of investment (have seen it done in Australia before).

Basically you buy *every* property in a small street then end the leases for all existing tenants (in a legal and reasonable way) and after they have left rebuild all the houses (and later be very fussy about the new tenants that you let move in).

If you can do that well (and the street is not surrounded by other bad streets) then there is a good chance you can create a nicer new street for people to live in that will actually attract people to it (and then eventually reap the rewards as the property values increase).

It isn't without risk and it isn't so cheap but it has a much better chance than buying a single property in an area that already has severe problems with crime and bad tenants.

But if the taxes are too high then even this approach might not work (so sometimes what look like "bargains" are actually very far from it).

It's a big file which consists of many smaller parts (blocks - which you could think of as "pages").

Every computer that runs the Satoshi client has it's own copy of this big file and it is fundamental to the way that Bitcoin can work as a decentralised P2P system.

The blocks contain all the Bitcoin transactions - so actually the "blockchain" is a "shared ledger" between all the Satoshi clients.

You already have that option by your choice of client (e.g. use one of the other clients such as Multibit or Electrum rather than the Satoshi one) - but what is being built under the hood now is much better than just a choice of "lite" or "full".

There is a lot of work going on to solve this problem by the devs - you can expect in a not too distant future version of the Satoshi client to be able to specify the amount of disk space you want to use to hold the parts of the blockchain that you need (which should be fairly minimal for most users).
