A number of the tube lines have large sections above ground.

A fixed wheel counts as a brake, though I've only seen the law in relation to bicycles which require 2 working brakes not sure how this applied to unicycles.

In Germany a fixed wheel does not count as a brake, and passionate fixie drivers will have a rear brake installed but never use it.

The signs on the rim of a brake that has been used is frowned upon by o̶b̶s̶e̶s̶s̶e̶d̶ passionate fixie drivers.

Sounds like the rules are the same actually

In the UK a bike is required to have 2 brakes, and a fixed wheel counts a single brake, i.e. you can't ride a fixie with no extra brake but you can with a single brake

In my experience R is king of happily chugging along spitting out nonsense results when it should have errored 100 lines ago.

The increasing prevalence of non-standard evaluation in R packages was one of the major reasons I switched from R to python for my work. The amount of ceremony and constant API changes just to have something as an argument in a function drove me mad.

Yeah, this was so very very painful. I once ended up maintaining a library that basically used all the different NSE approaches, which was not very much fun at all.

It's because you're in London. I have family in rural Cumbria with full fibre, yet none of the flats I've rented in London have availability.

I don't see how I could ever afford to retire whilst still having to pay rent in the UK.

If you've ever had to deal with the UK police as a victim of a crime, you'll quickly find out they're pretty useless at obtaining CCTV footage. I was asked to get it myself, to which the business who owned the CCTV told me they would only hand it to the police, so nothing happened.

The coachloads of Chinese tourists that I see every summer make me doubt this.

I think it was largely pushed by Phil Gaimon who was trying to get into the news to sell his new (at the time) book.

You can get some very permanent water-proof inks. Platinum Carbon black is my favourite.

Platinum Carbon Black is a wonderful ink. It seems to work very well in cheap fountain pens with flow issues. It’s highly resistant to coffee spills and looks ok on mediocre paper. Only drawback is cleaning it up; it cleans up like used motor oil.

De Atramentis, too, has a range of permanent inks which are quite fast-drying, too.

Happy customer for years.
