		<description><![CDATA[Many years ago, around 2000, I formed a limited company. A bunch of us wanted to rent a rack in a data centre and host our servers there, and it seemed wise to have a separate legal entity to sign the contract with the ISP for the rack.

This cost me some money here and there [...]]]></description>

And you have to tear apart the home you spent years building, while remembering all the fun times you had in the cold, empty, rooms [...]]]></description>

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[A friend has asked me to cast her some silver wedding rings. So I am adapting my aluminium casting experience to silver...

The thing to use for silver moulds is cuttlefish bone, which is soft enough to easily carve into shapes, but can withstand the heat of molten silver. For a single pour, at any rate.

		<description><![CDATA[At the Bristol Hackspace this evening, I powered up a Hall sensor.

The Allegro A1321 takes a 5v supply and outputs 2.5v - plus or minus 5mV per gauss of magnetic field in the sensor.

It turned out that small magnets don't produce many gauss, so I added a 741 op-amp with a gain of about 100 [...]]]></description>

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.

		<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[It's widely held that it's a scary experience for somebody to tell
their parents that they are gay. As a parent, therefore, I began to
wonder how I could arrange it so that, if any of my children turn out
to be gay, they could be spared any distress in telling us about it.

I surmised that the distress [...]]]></description>

		<description><![CDATA[I've been reading a book lately called "The Brain that Changes
Itself", which discusses a once-controversial theory that the adult
brain can rewire itself in the same manner as the developing brain,
with the main difference being that it just requires more effort to
focus the attention. It used to be believed that once the brain had
finished developing, its [...]]]></description>

		<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>
