What's the 'interesting new hypothesis'? Everything as reported here was already well known.

Who has the accurate map of overhead wires?

If you're 'BCBG' French you can't talk business until after the cheese.

However good the catalyst, and however resistant it is to poisoning by feed impurities, the energy for the conversion has to come from somewhere. Where? Even a 'perfect' system would merely be a store of that conversion energy.

50 years ago I wrote COBOL in near-plain language clear enough for the industrial client to check the logic from the source, with meaningful data-names. We input it on 80-column cards which had been 'interpreted' (ie content auto-printed in plaintext along the top of each card, to make debugging easier - just switch card/s), and the pack 'compiled' overnight, with 4 magical tape decks flipping away while we drank cocoa (sometime with rum) - hard drives weighed half a ton then, and only Government had them. With all the resources now available, things seem to have gone way downhill since then.

Germany has very little black coal, and no source of uranium. Even short of Lebensraum. Surprise us?

On some installations, it changes file associations so that online pdfs are opened by new Chrome instead of Acrobat. But in my country, government forms to be filled in won't work unless in a normal pdf reader. Had to change back the file associations for several cousins too. Check now and revert, if you haven't noticed this!

Note also that the people most at risk seem least likely to have smartphones with the desired Bluetooth feature, or recent enough to accept the OS updates necessary. Has the intended user-base ever been surveyed for compatibility?

Could have happenned every thousand years. We just think it's 'God' calling.

A hint to 'App' developers, whatever the source. Before making technical decisions, sample-survey the population you would like to be most active. See what cellphones they actually have (eg what version of Android, what available memory) and ensure that it will work for the majority. Note that it is quite possible that the older people who would be most at risk will have the least up-to-date handsets, and can't update even if they know how to. The fact that a system is technically possible does not guarantee that it is practically feasible.

If one stops calling it obsessional 'UBI', and looks at what's happenning with the UK's much-maligned 'Universal Credit', maybe evolution is in progress. Note also the practical snags when you try it.

We used to have 'The Workhouse'. It wasn't as bad as Dickens painted it.

You don't 'struggle to breathe' when short of oxygen. That's caused by an excess of carbon dioxide. So if the CO2 diffuses enough, the patient can still be dangerously low on O2, without showing distress. Buy a cheap oximeter for your finger and get used to your own readings - lower than 94% and you are in real trouble.

50 years ago in Britain, you shook hands on first meeting someone, and again when they left their job. If you shook hands with a friend or a routine business contact they would ask you what was being celebrated. When did the Continental habit invade?

Since when did it make sense for a shareholder to sue their own company? For misleading customers? Maybe the customers could sue for proven losses, or the sharholders could fire the directors in an annual meeting. What an odd systen the US has.
