Note that he's starting from N2 Japanese, which is already a high level of Japanese proficiency (although it does not test writing/speaking at all, so it's very feasible to have N2 yet be terrible at conversation). He's not exactly learning hiragana from M:TG.
The M:TG competitions are giving him a framework to practice that conversation, which believe it or not can be hard to come by in Tokyo without deliberate effort (see 'expat bubble'). The vocab/grammar on the cards is mostly incidental to all that. If he was playing online M:TG in Japanese he wouldn't be getting anywhere near the payoff.
> if I turn off Lock Screen notifications and turn on time sensitive notifications then will I get no marketing notifications, and only notifications about my driver turning up?
It's up to the app developer, they get to mark notifications as time sensitive or not. So if someone decides that because a coupon is expiring soon it's "time sensitive" to ping you about it, then they can mark it as such. Hypothetically Apple could frown on this in app review, but it isn't something app reviewers are likely to be able to reliably catch.
> Something that isn't talked much about IPv6 and I believe has subtle and indirect influence on it's adoption is that it is far far far less human-readable than IPv4
What? This comes up in like 95% of ipv6 threads on HN (see also: ‘they should have just added an extra quad to v4 addresses’)
