# New Feature: Post Labels

Now you might not see this too much since I plan to use the feature sparingly, categories and tags are both capable of sorting everything to a satisfactory level, but I’m using this thing that I just made to add extra little labels, which have a few cool uses.

# Self Hosted Password Manager: vaultwarden

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.

# Email Filtering With Sieve

Sieve, defined in RFC 5228 , is a programming language constructed for the express purpose of filtering email messages. And, on a Sieve-enabled server, it can do a lot of work.

# Shortening My URLs With tekdmn.me

Has anyone noticed that I’ve been giving out URLs of the form tekdmn.me and not teknikaldomain.me? Well, not only did I buy another domain that’s just a shorter version of this one, but it’s also, at the moment, the singular domain I have that’s 100% serverless. How? Cloudflare, obviously.

# Delta Chat: Instant Messaging Using... Email?

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.

# Using Cloudflare's HTTP/2 Server Push

For those unaware, when using Cloudflare to proxy your site, HTTP/2 support is usually on by default, and highly recommended, and you can also enable HTTP/3 too. But, for a while I thought that Cloudflare’s HTTP/2 would rob you of one of the really cool and touted features of HTTP/2: the server push. Well, as it turns out, that’s completely possible. Let’s dive in.

# Comparing IMAP and POP

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.

# A Small Issue With SMTP

SMTP, or, the Simple Mail Transfer Protocol, is the communications protocol that email servers (Mail Transfer Agents, or MTAs) use to talk to one another to… transfer mail. And SMTP has one glaring issue: A rather ambiguous “try again later”.
