Some people like to receive this blog via email. I previously used JetPack to send out subscriber messages - but it became increasingly clear that Automattic isn't a good steward of such things. I couldn't find any services which would let me send a few thousand subscribers a few emails per week, at zero cost. So, redecentralise! I installed phpList which is an open source email campaign tool. …

If your WordPress site has lots of plugins, it's sometimes difficult to keep track of what is manipulating your content. Ever wondered what priority all your various actions and filters have? This is a widget which will show you which actions are registered to your blog's hooks, and their priority order. It looks like this: Stick this code in your theme's functions.php or in its own plugin. …

A scrap of code which I hope helps you. Problem You installed the WordPress JetPack plugin and wrote all your blog posts in Markdown. Now you want to remove JetPack or replace it with a better Markdown parser. You turn off JetPack's "Write posts or pages in plain-text Markdown syntax". You click edit on a post and see the HTML version of your page. Where did the Markdown version go? …

Dan Q very kindly shared his script to make WordPress do good HTML. But I couldn't get it working. Looking at the HTML it was spitting out, the meta generator said it was HTML Tidy version 5.6.0. That's quite old! I confirmed this by running: echo tidy_get_release(); Which spat out 2017/11/25. Aha! There are a few bugs in this version of HTML Tidy, some of which are fixed in later…

Hot on the heels of yesterday's post, I've now made all of this blog available in text-only mode. Simply append .txt to the URl of any page and you'll get back the contents in plain UTF-8 text. No formatting, no images (although you can see the alt text), no nothing!

I've launched a WordPress Plugin for an extremely niche use-case. WP GeSHi Highlight Redux works with WordPress's Classic Editor to convert Markdown to syntax highlighted code. That allows me to write: ```php $a = "Hello"; $b = 5 * 2; echo $a . str($b); ``` And have it displayed as: $a = "Hello"; $b = 5 * 2; echo $a . str($b); I've previously written about the WP GeSHi Highlight plugin.…

I was noodling around in PHP the other day and discovered that this works: <?php $🍞 = "bread"; echo "Some delicious " . $🍞; I mean, there's no reason why it shouldn't work. An emoji is just a Unicode character (OK, not just a character - but we'll get on to that), so it should be fine to use anywhere. Emoji work perfectly well as function names: function 😺🐶() { echo "catdog!"; } 😺🐶(); De…

Because I'm a grumpy old man, I don't use Gutenberg or Block themes on my WordPress. Instead, I write everything in Markdown. When I write code snippets in Markdown, they look like this: ```php $a = 1; echo $a; if ($a < 5) { // Do Something return thing( $a, true ); } ``` But I want to render that with code highlighting. I was using the Prismatic Plugin. It is excellent and very…

A few weeks ago, I built an ActivityPub Server in a Single PHP File. It's a proof of concept showing how easy it is to turn a website into a full-featured Fediverse participant. After a bunch of feedback and testing, I've added a some features to make it slightly more useful. A single PHP file - 45KB of no-library goodness. Just add your details, upload, and done. No databases. Everything…

Any computer program can be designed to run from a single file if you architect it wrong enough! I wanted to create the simplest possible Fediverse server which can be used as an educational tool to show how ActivityPub / Mastodon works. The design goals were: Upload a single PHP file to the server. No databases or separate config files. Single Actor (i.e. not multi-user). Allow the Actor to…

I've written an ActivityPub server which only allows you to post messages to your followers. That's all it does. It won't record favourites or reposts. There's no support for following other accounts or receiving replies. It cannot delete or update posts nor can it verify signatures. It doesn't have a database or any storage beyond flat files. But it will happily send messages and allow…

I'm a little bit obsessed with building eInk displays. They're pretty cheap second hand. They're low energy, passive displays, with good-enough performance for occasional updates. Here's a new one which shows me what the current cost of my electricity is: Background After installing solar panels, a smart electricity meter, and a solar battery - the next obvious step was a smart energy…
