I must be an engineer for a different Network Rail

Agreed. In addition to yours, notions like limits/colimits, equalisers/coequalisers, kernels/cokernels, epi/monic will be very hard to grasp a motivation for without a breadth of mathematical experience in other areas.

Like learning a language by strictly the grammar and having 0 vocabulary.

Shivlov for the one and only text in linear algebra is rough. IMO, it’s a little terse and fast paced. Efficient if you’re already well versed enough to be dangerous, but otherwise I think might slow down the beginner to a crawl in places.

Same for Hartshorne’s Algebraic Geometry. Neither of these are bad textbooks at all, they both have a place on my bookshelf, but certainly better options have appeared through the years (for AG, I’d be remiss to mention Ravi Vakil’s fantastic The Rising Sea, due for a physical publishing October, and Ulrich Görtz & Torsten Wedhorn two part series)

I hope I’m not adding 2 + 2 to get 5, but it’s incredibly convenient that a lot of people are being charged for supporting a proscribed group the same month as the online safety act is rolled out…

The cynic in me almost wonders if when it comes to re-election time, these increased numbers in terrorist charges will be trotted out and the context conveniently forgotten.

I don’t think it’s dumb - hasty and premature perhaps. Manufacturers have been shipping boards with flaky RVV support, a years old kernel and undocumented blobs on in house baked OS and calling it a day.

Feels like a step towards strong arming them into shipping products that can be supported easier/not being left to rot in a drawer.
