mastodon 4.5.8

Graduated in mathematics over 40 years ago. Spent career in engineering R&D (communications and security). More RFCs than other publications. Retired. These days I spend too much time on some probability software (ask for version to run locally free, website coming). Also a problem setter for New Scientist and a trustee of the Friends of my local museum.

I'm generally on the anti- side of discussion of Jackson's films. But credit where it is due, "one does not just walk into Mordor" is a good line. And one does not just sail through the Strait of Hormuz.

Deliveroo (yes, I know I shouldn't use them) have a reasonable security process where you are given a two digit code on ordering to give to the person delivering (who I do tip when the option is given). At least it was reasonable except that for some reason my code seems to have frozen, it's now always the same code. (No, I'm not posting it.) Probably not much difference in security in practice, but why make such a change? (Or not notice the change when something else is changed would be my guess.)

@cstross@wandering.shop I lost days due to covid this last year. But as I'm retired (early, though in a couple of months only early because they raised my pension age) that doesn't matter to them.

@cstross@wandering.shop Discussion online with some Americans indicates that for all their healthcare provision issues, they can get free covid shots just by turning up. (I don't know if that's just some states or national, but it was all who commented.) In fact no other country represented in that discussion (typical richer countries) had the not unless you pay (and it's not cheap) position most of us have. (I used to qualify sometimes, but no longer. A friend whose wife does get a free shot doesn't himself get one as her carer.)

@davekarpf Yes, but. The but would be how you consider earlier examples of founders who became cult figures. From the twentieth century that would include Henry Ford and Walt Disney, and from the late nineteenth and early twentieth century Thomas Edison. There are many more. Are these the same phenomenon, or a different one?
