# Giving My Sitemap Some Style

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.

# 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.

# Email Filtering With Sieve

Sieve, defined in RFC 5228, is a programming language constructed for the express purpose of filtering email messages. And, fun fact, 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.

# 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.

# AbuseIPDB Checking With Postfix

So if you’ve not heard, there’s this website called AbuseIPDB, which, no affiliation, is a website where webmasters can submit reports of abusive IP addresses, and then query those reports, either manually, or using their REST API. And this is how I did exactly that, to help cut down some of the spam on my email server. Let’s get started.

# Temperatures as You Like

So here’s a short one for you: Do you like your temperatures expressed as °F, or °C?1

Well, there’s one fundamental issue with me writing like this. I can put, say, “I decreased temperatures by 20°F by cleaning the fans,” but if you’re a °C person, then you need to take a quick detour to convert that to units that you’re more familiar with. A common way to do this would be to notate that as “20°F (11.11 °C)", which works, but I’m effectively stating myself twice, and hoping that I actually got my numbers right. Plus that opens up the possibility for writing °F (°C) one time, and °C (°F) another. So for basically no benefit except me getting to be proud of myself, let’s improve on that.

# Teknikaldomain.me Website Architecture Overview

So I just checked in with initialcommit.com, the website run by Jacob Stopak, the same person I collaborated with to help explain the internals of version control systems, not once, but twice even. And he published an overview of how he made the site, and what tools he used. As I was looking, I noticed, we took a very different approach to get to two similar endpoints.

If you just want to see what I did, read on. If you want to see the differences, or are just curious about the various ways that sites can be built, read his first, then come back with that knowledge in mind.
