Please consider diverting your efforts to OpenStreetMap! The TIGER-derived basemap still needs fixup, but your work will benefit everyone, not just the Google shareholders who ultimately own Waze.
Switching modes like that was common practice on the Amstrad CPC (which used the same 6845 video chip), but as time went on, people also learned how to change the base address of screen RAM part way through each frame. This gave you super-smooth hardware scrolling for the main game area while still retaining a static score display. Unfortunately it came too late in the machine's history to be used for more than a handful of games, but demo coders used it extensively (and still do).
Disk was already the standard spelling in the UK by 1984 (in a computing context), just as program was used in preference to programme. But Amstrad mistyped it as disc on the plastic mouldings for their first CPC, and were too cheap to change them. Consequently CPC 3in disks were always called discs even into the 90s.
Interesting! I've recently plumped for UIKit (with bits of SwiftUI dropped in) for a new mapping app because, as you say, SwiftUI map support is virtually non-existent. Have you thought about adding Maplibre support as an alternative to MapKit?
Organ improvisation is a remarkable art, whether or not accompanying a silent film. In any of France's great cathedrals, the foremost musical experience is to hear the "titulaire" (essentially the headline organist) improvising on whatever theme they've selected for the day - sometimes chant, sometimes a hymn tune, sometimes something entirely frivolous and inappropriate that takes on a life of its own.
Even here in the UK, where it's not such a big thing, there's often an enjoyable few minutes at evensong where the organist improvises in the gap between finishing the prelude and the choir processing in. But France does it like nowhere else. One of the finest musical experiences I've ever known was Olivier Latry, titulaire at Notre Dame, giving a recital at Worcester Cathedral. After the appointed recital, he performed a 20-minute improvisation on the hymn chosen for evensong earlier that day (Herbert Howells' "Michael"), which he had never heard before. Superb yet entirely ephemeral - like most improvisations, it was never recorded.
It’s second nature very quickly. Our train into Oxford leaves at ten past the hour. You find yourself thinking “oh, I’ll aim for the ten past eleven” an hour or two beforehand and organise your morning accordingly. It’s absolutely no hardship.
So far it seems to be making a noticeable, albeit modest difference. Traffic in the city centre is clearly reduced. Buses are no longer queueing for ages at the Plain (the notorious roundabout that connects East Oxford to the city centre) - in fact, bus journey times are improved throughout. There are some knock-on effects, particularly in North Oxford in the evening peak, but generally it's working well. Footfall in the city centre remains high according to official figures, and certainly it was pretty rammed yesterday when I was doing my Christmas shopping.
It's only the third congestion charge to have been implemented in the UK, after London and Durham. (The Oxford scheme thus far is a slightly watered-down version of the full "traffic filters" mentioned in the review, because of the overrunning closure of the bridge by the railway station which cuts off one of the main routes into Oxford.)
So Tolkien was right. Ignore the conspiracy theorists. Have courage and fight back. Cars in historic city centres like Oxford are not something we have to just accept.
For UK readers, this is eerily similar to the typeface originally used on the "Thames Turbo" trains (class 165/166) from their construction in the 1990s until a refurb about five years ago - I could believe it was the same manufacturer. Some photos:
