Build it and they'll come? At least one end has to be somewhere people want to be, right? A line from London into the countryside makes sense. You can live in the countryside and work in London. A line from nowhere to nowhere is a chicken/egg problem. Now if one end is an Airport and another is a new community who will have jobs at the airport, that might work.
I think so - I started doing a binary search >50000 -> <75000 -> <65000 -> <55000 -> <52500 then wondered if it was 50000, so guessed that. It said I was right, well done, the answer is indeed 02563!
Do you take the money, or do your users split it between their friends and you take a cut?
The take the money one has been done (Beeminder, and others probably), but sure different flavours are welcome.
The split with friends I haven't seen. That would be pretty cool, especially if you can do it without needing to pay banks a txn fee, or perhaps a tiny one (maybe you take a 5% of profits fee from participents, or similar). Crypto is the other option (!).
The split with friends is great becuase
* People less likely to lie to friends than a SaaS. Which is good for both parties.
* Social motivation and financial motivation.
* If you lose it's like losing a game of poker with mates, not a big deal (as long as you kept the stakes reasonable).
Except chronic fatigue / long covid could affect IQ as tested. It might be that you have the CPU but the power supply isn't up to voltage, so to speak, so the CPU has to run slow.
Yes this sort of thing! There was one posted on HN back where the speaker says, in the middle of other context fairly deep in, recognise this number? 3.14159265358779323846264338327950288419, and then shows that it isn't actually Pi, (one of the digits is swapped, he may have swapped a different digit to me). Nice joke because is reminds us to challenge assumptions too!
I like a joke that is about the subject matter. A subtle pun that makes a smile but doesn't interrupt the flow at all. Another way to make it entertaining is make it a story. Forget jokes, make it about how you had to mop up the leaks in the server room as an intern before getting to the rack that had the crashed hard disk. Or something.
I remember the first meme like presentations back in 2002 at work and I hated it. It's like stop learning, now you have to find this picture funny (maybe it was some star wars reference, and I haven't watched them), and we will get back to it. It was cringe!
