4€ will get you two (pretty small by US standards) scoops of ice cream or three beers in a shop in Germany. In a cheap bar, you might get a beer for 4€ though the average is much closer to 5€ these days.
If you can't transfer the course's material onto new, unseen questions, then you might have memorised it, but you didn't understand it. Getting an A requires understanding, not rote memorisation.
Even if it was still a thing (and it really isn’t, imo), libimobiledevice does a decent job already, and given a little funding it shouldn’t be super hard to close the gaps and build a nice UI on top of it. But that’s not happening because very few people care about it at all.
Now, AirDrop support is a completely different beast. But it requires hardware support (promiscuous mode, iirc) that many common chipsets simply lack.
Good news for you! 1.5 is in O(50) since they’re both constants! (It’s 1.50 because the author has the 58€-a-month flat rate ticket for all local and regional services in the entire country. If you buy a regular ticket, you get back 25% of the ticket price for delays over an hour and 50% for delays over two hours)
Your comparison to Windows is probably more appropriate than you think. When is the last time Windows crashed on you (and it wasn't a dodgy third-party driver that caused it)? It works fine for nearly everyone using it. So does WhatsApp.
1. Settings → Chats → Disable "Save to Camera Roll", done.
2. WhatsApp has rock-solid message delivery, otherwise it wouldn't have 2 billion users (https://blog.whatsapp.com/two-billion-users-connecting-the-w...). It's the default messaging app in most of the world. You don't become that popular with unreliable message delivery.
It's likely that your spine will have sustained some damage in an accident that jammed your doors. That means you want level extraction, which requires removing both driver's side doors and the B pillar ("total sidewall removal"). Pulling a healthy person (or an injured person if they need to be removed from the car right now) out of a car is easy, doing it without further spine damage is a lot harder. Practising it is great fun, though :)
That means "don't step into traffic". It doesn't mean "you're not allowed to cross the road unless there's a pedestrian crossing". Crossing the road outside of marked pedestrian crossings is perfectly legal here (Germany).
"(3) Persons on foot shall rapidly cross lanes on the shortest path transverse to the direction of travel, taking into account vehicle traffic. If traffic density, speed, visibility or traffic flow so require, a carriageway may only be crossed at crossings or junctions, at traffic lights within markings, at pedestrian crossing aids or on pedestrian crossings (sign 293). If the carriageway is crossed at crossings or junctions, pedestrian crossings or markings at traffic lights shall always be used." - translated with deepl from https://www.gesetze-im-internet.de/stvo_2013/__25.html
Finland accounts for around 1% of the EU population, that's hardly enough to make claims about "Europe". Speed tiers don't happen in most countries (I can say this with certainty for the UK and Germany).
