If you’re just curious, MTA-STS relates to SMTP, in the same way that HSTS relates to HTTP. Except, naturally, it relies on, you get three guesses… yes, DNS. And this is what it is, and how to set it up.Continue reading
So here’s the thing about SSH: The first time you connect to a server, you have no real idea of if that’s legitimate or not, right? Well, you could compare the key fingerprint to the fingerprint that the server admin gave you and make sure they match, but nobody does that.
Well… there is a way. Using everyone’s favorite always-broken service, DNS.Continue reading
So this is a fun one, and likely a long one. Come, let’s talk about the unlikely backing for a decentralized, privacy-focused communications platform, the very weird ways in which IMAP can be used, and a hopefully final wrap-up to my streak of rambling about PGP.Continue reading
There’s a few common ways to do this:
- Web Key Directory
Let’s discuss how they all work.Continue reading
Pretty Good Privacy, or as it’s more commonly known as by its most popular client’s name, GNU Privacy Guard, is a method of encrypting and/or signing your messages using the power of public key cryptography. And, while it can get extremely complex, the basics of using PGP are, actually, pretty simple. So in the words of the great Angus Deveson, Let’s get started.Continue reading
For those of you that have ever tried to setup email on your phone that’s more than just GMail, you’ve likely been asked how you want to access the account, either POP or IMAP, and were likely told the difference is that “IMAP keeps messages on the server.” Well, let’s go over the specific differences here, to actually give a more complete understanding of what each protocol is like.Continue reading
Git and Bitcoin: the Similarities
Fun fact: I’m writing articles on initialcommit.com now! I’ve worked with Jacob in the past to bring you the evolution of version control systems (go look that up there, hugo doesn’t like links in the body of link posts, hah), but now I’ve actually got articles under my name there. If you like Git things, check it out.
Anyways, to the point. Did you know that Git and Bitcoin are actually based on some very similar concepts and at the very low level are nearly identical in implementation? In the two-post series over there, I pick apart just how closely related the two are.
So here’s a fun one.
Have you ever noticed that even for huge changes to a repository, a
git push only sends over a few kilobytes, maybe a few megabytes at most?
If you’re familiar with the internals of git, you know that git stores an entire copy of the new file on commit.
So how are these changes so small?
