I don't think you can actually have the "unlimited downside" at least as a casual investor. Nobody trusts you to be able to pay up for the "unlimited downside", so when you short stock, you are required to provide s

I don't understand why Tether would be doing all that. They could have a very simple business model: 1. Accept USD and issue USDT in return, 2. Buy US Treasury bonds, which yield 1.5-2.5% for 3 month to 5 year bonds, 3. If people cash

We don't know what the actual bug is yet, or how easy it would be to exploit it. People are speculating that either: a) It would allow any non-root process to read full memory, including the kernel and other processes, or b) It would

Yes, the algorithm is breakable with a few examples to figure out the base word and the pattern. But this requires human attention at your personal algorithm. Unless you are enough of a celebrity or public figure to be personally targeted

You can't blindly overwrite existing data based on the UUID, sure. But I find that the security checks against "stealing UUIDs" are much simpler to implement than a system of composite primary keys (deviceid+autoincrement or

The Algorithm is a great solution - breaking the pattern would require password leaks from 3-4 different sites, and a human to spend time puzzling over it. For automated bots the passwords look unique. What's your solution for annoying

UUIDs (and other mostly random IDs) also have the important advantage that they can be generated offline - in mobile apps, client-side javascript or elsewhere. With autoincrement keys, you need to either contact the database server for each
