I used to have an Amiga 600 with a 2400 baud modem. I can't remember the name of the BBS I mostly connected to, but the telephone number was just passed around word of mouth.

I lived in Lincolnshire in the UK, a pretty rural county - not very wealthy. It was a local rate number - same area code and it meant free calls. The person who ran it had a pretty big switchboard so could handle about 10-20 connections at once.

The best thing about it was it had a persistent MUD running. You had a character which moved around room to room, slaying monsters but also PvP. If you killed the other person you got all their stuff. One of the problems was if you logged off your character just sat there and would only rudimentarily defend themselves if someone else came along. So you'd need to find somewhere in the middle of nowhere to leave them.

Now the _really_ great thing about this BBS is the owner also had a Compuserve connection. He had it set up so you could trade gold pieces in the MUD game for Compuserve credits - minutes on the _actual_ internet.

I remember finding a logged out player, killing them, getting a jackpot in gold coins and then eagerly spending them to get on Compuserve. It was the first ever time and I didn't really know what to do. I seem to recall their was a directory of _all_ the websites in a big listing with their corresponding index numbers. You could then browse over and take a look.

It felt like some crazy magical sci fi novel at the time. I was about 11 or 12 back then - very early 90s. Just before the blizzard of AOL trial CDs hit the UK.


I enjoyed the talk - thanks for doing it. There's an alternative though to the final approach of using a class template. You can actually do a typealias which fuses together multiple protocols into a single type. I've done a small example here:

One of the protections there is that if you delete an app from your phone, you've got the option to also delete all of it's data from HealthKit. Still agree it's a pain though when it does happen.


I'd imagine that to begin with medical professionals will only allow this on approved devices (the originating device is stored with the sample). Given that certified devices have to work within defined tolerances, they'd then be able to know roughly how good the data they're dealing with. I guess there's always going to be cases of user error in equipment use, but that's part of what has to be considered when designing such a system.


Thanks for that - you've caught me being a bit ambiguous. I've corrected it now.

What I was intending to say is that your HealthKit store itself is never transmitted as a whole /except/ as part of an iCloud backup. Apps can of course move individual data points around with the users permission so long as they say so in their privacy agreements.

'The recorded data is of an incredibly private and personal nature and they’re preventing HealthKit stores from being passed over any kind of network except as part of a secure iCloud backup'
