Adding multiple h-feeds to the same web page

I maintain a web page that lists notes from IndieWeb events. Entries are added to the page when notes from meet-ups are archived to the community wiki. This web page contains several h-feeds. h-feed is the microformats markup that says that the tagged area represents a feed....

What I associate with my name

Ava and I are trading blog post titles. The topic Ava chose for me to write about was “What I associate with my name”. When I was young, I remember distinctly looking through a kids’ encyclopaedia and finding “James” written in there a few times [1]. I don’t know why that me...

Proust’s questionnaire

Zachary’s website introduced me to “Proust’s questionnaire”, a series of questions by Marcel Proust. I thought it would be fun to try and respond to them! I am writing this blog post as the snow falls outside. I wasn’t expecting snow today, but here it is. Some of the most w...

A sandwich questionnaire, part two

Ruben, after responding to the sandwich questionnaire that Zachary blogged about, added a few more questions. When I saw the blog post, I thought: these questions are exactly what I need today. Below I have responded to the delightfully-named “second helping” questions that R...

I still remember being in the audience back then. James is an amazing guy! Looking forward to seeing him on stage again! 😁 (Make sure you’re there, too. 😉 Also check out his book, Feck Perfuction – so good.)

The inverted index pattern

In “Build a search index in Python”, I walked through how to create a search index using the “inverted index” structure. This structure is commonly used in document search. This week I was thinking about “inverting” data is more broadly applicable in software engineering tha...

Designing for inactive users: Account check-ins and deletion

Artemis has been open for registration with an invite code for over a year. In that time, many people have signed up. With that said, not everyone who signs up will end up using their account. This is par for the course with software. Signing up for an account doesn’t mean so...

Redesigning the Artemis account deletion back-end

As I have been building Artemis, I have learned that the account deletion flow requires constant review. For example, whenever I add a new database table, I need to make sure that table is in the account deletion flow. I may also need to create an index in the database so I c...

Performance-wise, Safari on iOS apparently doesn’t seem to like the over-engineered CSS custom property calculations for fluid type and all the other stuff in my little style mixer. 🙈

But hey, my personal site is my playground, right? ¯\_(ツ)_/¯

Notifying users of page updates

Some time in January, I was going through my browser tabs and came across an Artemis tab that had been opened a while ago. But it took me a moment to realise that the tab might be out of date. My eyes went first to the posts from authors to which I have subscribed, then to th...

Brainstorming source code editing for web applications

Last year, I worked on a bookmarklet for editing pages on my website. When clicked, the bookmarklet would open the page in GitHub that corresponded with the page I was viewing. I used the bookmarklet so much I turned it into a browser extension, which I still use regularly to...

Drawing and hand-written fonts

I have been thinking about hand-writing and websites in the background for a little while. I made a hand-written font using Calligraphr a few months ago. I enjoyed making this font, but haven't used it for a web project yet. Here's what it looks like: While making the font,...

Webspace Invaders

A couple of weeks back, I’m sitting at my desk when a direct message from my frontend friend Kevin Powell pops up. Kevin’s a genuinely kind guy. He makes CSS videos on YouTube and he’s got this way of explaining things that never makes you feel stupid for not knowing them al...
