Apologies for radio silence
I'm sorry to have been quiet on posting here for a while.
The ongoing breakdown of my powerful but ageing Alienware laptop has been one factor. I had hoped to record several videos in the last two weeks, but as anyone who tried to listen to my last YouTube video would know, the laptop's sound and video recording are disastrous. So, I have ordered a new laptop (an Asus zenbook pro duo ux582) and I'll take delivery of it in London next Tuesday (I'm being interviewed there, and buying it in London means that I'll get a laptop with a UK keyboard rather than a European one with keys--umlats etc.--that I don't use).
I've also been flat out writing presentations to give over here--ones that I had hoped to record and post here, but for the above reasons, couldn't.
So, the silence will become an avalanche in a week or so, once I have the new laptop and I can record the talks that I have given over here (in Poland, Denmark, and--after next week--France).
