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.

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 s...
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 ...
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 But it took me a moment to realise that the tab might be out of date.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 t...
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 t...

”I like to say that I was a garlic smuggler for the mafia, which I was, but there’s more to the story than that.”

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...

An Orchid!
There was considerable excitement out on the terrace a couple of days ago, because The Squeeze had noticed two very definite flower spikes emerging from a plant that has mostly just sat there for the past couple of years. At first glance I thought it might possibly be Chinch...

How very pleasant. Today’s quest was just to the side of what some people cite as the jewel of the Renaissance architecture, [Bramante’s Tempietto](https://en.wikipedia.org/wiki/Tempietto_del_Bramante). I couldn’t get any closer today, though I have been inside on other occasions.
