In other news, I haven't actually bought much lately. But I am moving houses relatively soon and will have more space for my lab.
The poster in question is, in my not so humble opinion, and based on observations over several months, only borderline sane. Sane enough to not get swept off the streets by a team of men in white coats, but not sane enough to be allowed to play with things that require expertise to avoid killing or maiming oneself or others. I can't help but be reminded of Niven and Pournelle's
"Think of it as evolution in action". The appearance of some videos from him, with frequent hand-rolling of *ahem* cigarettes, generates a new perspective that to my mind certainly explains a lot of his past postings.
I'd previously wondered whether he was a young but bright teenager or even younger who was just charging headlong into everything that seemed interesting without slowing down enough along the way to learn how anything actually worked. There was a lot that spoke of much immaturity, coupled with a certain kind of enthusiastic but unfocussed curiosity that often goes with bright young men. Now that I see that he's 35 or so the evidence of immaturity takes on a completely different flavour.
Footnote.
Quoting Niven and Pournelle made me realise that I'd completely forgotten that I once shared an office with Jerry Pournelle for a week back in the 90s. He wrote a column for our US backed but UK published magazine, and for some reason the powers that be in the US (who paid for his column at 'star writer' rates) had decided to billet him with us for a week for him to "
Get a flavour of what they're doing in the UK". A self-confessed 'paleo-conservative', he was as much of a sexist knuckle-dragger as you might expect from some of his writing; his trying to send our [female] Deputy Managing Editor off to "
Get me a cuppa coffee dharlin'." did not go down well, and during the week there were other incidents that suggested that he hadn't quite caught up with the times as to how one approached professional women in the 1990s. I recall having to persuade some of the ladies that pitching him from a sixth floor window was likely to go down very poorly with our US publisher who paid our inflated salaries.
