		<description><![CDATA[This year's going to be pretty busy with settling into the new home, but I have a few projects.


Finish the ring casting I nearly finished before the move. That's a priority.
Resurrect my aluminium foundry. In particular, it's our bronze wedding anniversary, so Sarah's going to design a pattern for a sundial, which I will cast [...]]]></description>

		<description><![CDATA[When I was a child, I had a lot of technical books lying around. My grandmother was a science teacher and my grandfather was an engineer, and lots of their old books lined my shelves. And alongside them, I had a lot of science fiction, too. And from all this, I learnt that technology could [...]]]></description>

		<description><![CDATA[In The Lord of the Flies, the children (marooned on an island and working out how to organise themselves to survive) develop a technique for managing debate: they use a conch shell as a token to represent who currently holds the floor. Without the conch, you can't talk; you have to wait your turn.

		<description><![CDATA[Currently, you can go to various providers and buy online storage capacity (IMHO, rsync.net is best, after research I did to find an offsite backup host for work). It's more expensive than a hard disk in your computer, and miles slower, but it has one brilliant advantage: it's remote. So it's perfect for backups.

And that's [...]]]></description>

		<description><![CDATA[Pondering Bitcoin, I recently opined:

Who sets the difficulty of the puzzle and all that? The computers in the network do - when the system was created, rules were agreed, and written into the software. As everyone runs software following those rules, anybody solving easier puzzles or trying to award themselves more bounty for doing so [...]]]></description>

		<description><![CDATA[My recent thoughts about bitcoin reminded me of earlier thoughts I'd had about digital currency.

Cryptographic digital currency is a way of transferring value without trusted third parties being involved in every transaction, but within a closed domain, it's easier to go for a trusted party and cut out all the crypto maths. Which is why [...]]]></description>

		<description><![CDATA[I've been learning about Bitcoin lately.

It's an electronic currency. I've seen electronic currency before - in the late 90s there were efforts to create them based on virtual banks issuing coins. The coins were basically long random serial numbers which, along with a statement of the value of the coin, were then signed by the [...]]]></description>

		<description><![CDATA[I was enthusiastic about IPv6 when I first read of it, in the late 1990s. Mainly, I liked the autoconfiguration, and the inbuilt support for anycast and multicast, which are used to great effect: there is s standard IPv6 address for "my nearest time server" and the like, which has various benefits.

However, it comes at [...]]]></description>

		<description><![CDATA[One of my too many projects is to make a wearable computer.

Lots of people are interested in making wearables, but nobody's yet come up with one that hits a "sweet spot" of decent functionality along with it being unobtrusive enough to not be a pain.

Well, I'm a nerd, so I'm far happier to put up [...]]]></description>
