DIY Password Manager

The problem of coming up with a good password is finding something memorable enough that you will remember it, but not so obvious that it’s guessable. A password manager essentially makes sure that your passwords are not guessable, but it also makes them impossible for you to remember them, so you have to outsource remembering your passwords to a database on your computer or in the cloud (i.e. on someone else’s computer).

Introducing: Totally Exchangeable Tokens

NFTs are all the rage these days, but I’m here to tell you about the next big thing. But first, let’s talk about what’s wrong with NFTs. NFTs – Non-Fungible Tokens – give you a way to secure ownership over a hyperlink to an image. That ownership is secured by its being stored in a ledger, and that ledger is decentralised and cryptographically secure. Now, that’s a really exciting prospect, but there are problems. Read more
