http://gisli.hamstur.is/2014/10/receiving-bitcoins

October 2, 2014, in bitcoin. Some of you might be aware of the other Bitcoin blockchain. Which is mined in parallel to the main blockchain. And since coins on testnet are entirely worthless we can develop safely without our mistakes being too costly. Testnet coins are worthless - but useful. They are useful because they are worthless. Maybe not so surprisingly Xenog. One of the developers of Haskoin, is such a volunteer and using his faucet. Moments later to my wallet. To seed our peer connections with a...

Optical-mouse scanner and location awareness. February 18, 2010, in robotics. One of the problems in the world of moving robots is the task of figuring out where robot is. One way is to mount a GPS-module on the robot. Simpler solutions might include methods that measure how many rounds the wheels have spun and (with the help of the diameter of the wheels and our friend π) calculate the distance travelled. What if the wheel spins or slides? Then the robot thinks it’s further along than it actually is.

http://gisli.hamstur.is/2014/08/bootstrapping-haskell-for-bitcoin-development

Bootstrapping Haskell for Bitcoin development. August 20, 2014, in bitcoin. It’s time to get our hands dirty. Let’s begin bootstrapping our Haskell development environment. Before we proceed it’s probably fair to note that it’s. Early days for Bitcoin development using Haskell and like users of most languages one should expect the Bitcoin libraries to be changing rapidly. Never the less the authors. On top of the library. Please consider signing up for their service to show them your support. Mkdir test-...

http://gisli.hamstur.is/2014/08/bitcoin-wallets

August 13, 2014, in bitcoin. In this blog post I’m going to concentrate on Bitcoin wallets. Which will be our foundation for a more developer-oriented discussion. Wallets are analogous to web browsers in that they are the main interface for end users to interact with the network. In its simplest form it is a file which contains a collection of private keys. In addition the wallet software usually takes care of communicating with peers, managing the blockchain and keeping records of wallet transactions.

Bitcoin from a developer's perspective. August 3, 2014, in bitcoin. Is an exciting new technology invented by the mysterious Satoshi. In 2009 which has been gaining some serious traction in the last few months. Although there are many introductory blog posts about Bitcoin there aren’t necessarily many which tackle the subject from a developer’s perspective. To further explore the possibilities of Bitcoin I’m going to be experimenting with it by writing some Haskell. Since the database is distributed wher...
