It’s very loud in Kyiv.
Explosions.
Missiles and drones.

I don’t know what else to say.

A dark, horrific night for Kyiv. I can hardly remember russia ever bombing this many apartment buildings in a single terrorist attack here.

A hard night in Kyiv.
We’re under massive attack.

The mayor reports damage across the city.
It feels like being trapped inside a strange game –
only this game is reality.

2:43 am in Kyiv.
The awful attack continues.
I don’t want to repeat the same words.
I’ll write to you in the morning –
I hope it comes.

We are in a stock market 'tech bubble', driven in large part by over-investment in AI companies.

It's starting to unravel and the downside will be like 1987.

It should be a fun few months...

Greetings from Kyiv,
where the night was calm.

I finished writing Sunday Letter
and went for warcoffee at a bookstore –
found a treasure: History of Ukraine by Mykhailo Hrushevskyi,
the historian and statesman who shaped modern Ukrainian identity.
First published in 1921.

Mate of twenty years has cut me off because he thinks I'm trying to sleep with his other half. Tried to explain I think she's an terribly unattractive, but this seems to have made things worse.

Warcoffee time in Kyiv.
I visited two exhibitions today,
and now I’m resting among books.

Ukraine is an amazing country.
I’m here to tell you about it.

I'm seriously considering converting my bicycle trailer into a micro-camper.
Need to play around with some design ideas. Currently thinking of it unfolding (a bit like a rooftop tent some cars have).
But it must be lightweight, so probably coroplast.
