Federation, the driving name behind decentralized and self-hosted software. But what is ‘federation,’ really? Well, there’s the really complex answer, and the simple answer. The simple answer is that federation is when multiple unrelated instances of a piece of software are capable of communicating and sharing between one another. The long answer, well, if you want to see that, then…

OTR: Encrypted Instant Messaging

2021-06-30 9 min read Cool stuff Privacy Tech Tech explained Teknikal_Domain Unable to load comment count

Yes, for once, I have not just some app for secure messaging, this time, it’s a protocol. OTR, or Off-the-Record Messaging, is a protocol for establishing end-to-end encrypted messaging between two participants over a standard instant messaging channel like IRC or XMPP (Jabber). It also allows for deniable authentication, where during the conversation you can be assured that only you two are talking, but after the conversation, there is no way for an outside third party to 100% prove you talked, since it’s theoretically possible for an attacker to have forged the communications record. It’s complicated, but not too hard to wrap your head around.

So I take it some people reading this are familiar with what I’ll call a ‘remote filesystem protocol’ like NFS , SMB , or AFP . Well, did you know there’s one that’s found use in a few places and you’ve maybe heard of once or twice, and really… well, doesn’t sound like it should make any sense? Welcome to WebDAV. The remote filesystem that runs over HTTP.

This is where I’d usually make some joke about “if you remember, back in the day…” but… given how Freenode and Libera have been in the news recently for Freenode’s rather hostile takeover (and suicide), You probably know what IRC is. So. IRC, or Internet Relay Chat, is a really old (as in, 1988) protocol for text-based communications between users on a network. And the cool part is, it’s so simple that it’s almost funny. Like, let’s take a look. You could actually, with only a few minutes of reading, just enter raw IRC protocol lines by hand and have a perfectly valid and functional session.

Matrix: Decentralized, Federated Chat

Do you like secure chat apps? but actually secure, not like Telegram? And end-to-end encrypted, if selected? And ones that support sending media, and files, and even voice and video calls? And completely decentralized meaning you don’t need to rely on any one company or any one third-party server?

Well do I have a deal for you: Matrix.

Giving My Sitemap Some Style

2021-03-03 6 min read Behind the scenes Blog improvements Tech Web stuff Teknikal_Domain Unable to load comment count

Now I know I’ve talked about sitemap.xml before, but quick summary: that’s an XML file that has a list of every (public) URL on your site, to make it easier for crawlers to index your entire site since that list (or, map) lays it out. Well as an XML file, it can take XML style sheets, in a format called XSLT, short for XSL Transformations, short for eXtensible Stylesheet Language. Yes, it’s XML all the way down. But, if you’ve looked at my sitemap, you’ll see I’ve gone and done it. This is how.

Graylog, and the Syslog Protocol, Explained

2021-02-19 9 min read Software Sysadmin stuff Tech Tech explained Teknikal_Domain Unable to load comment count

So if you’ve tried enterprise log management systems, you’ve likely heard of Syslog. If you haven’t, Syslog, is, well, a protocol designed to allow multiple hosts to send their system logs over the network to some other server where they can be analyzed and stored. It’s another one of those weird UDP protocols, and this one is actually stupid simple, even in both of the commonly used forms! Oh, we’ll also cover the one piece of software that I use that handles Syslog — Graylog, which by itself is also really cool.

Updated May 1st, 2020

You familiar with Bitwarden? It’s another one of those password manager services that comes as a browser extension or standalone program, and allows for things like storing TOTP keys, generating new, secure passwords, and all that fun stuff. Except unlike others that I’ve seen, it has one difference: You can self-host an instance. Though, their self-hosted options look a little lacking unless you want to give them money. Well as it happens with an open sourced project, someone decided to create a Bitwarden API compatible server, thus creating vaultwarden. And this is why it’s cool.
