CTC25 – Creating and Sharing Openly

Date: 19th – 20th February 2022
Tickets: https://ti.to/code-the-city/ctc25

We had a really productive session over the weekend. We’d four projects running. Where these produced code you can find it on Github. We added the event itself to Wikidata. And for each project, we’ve linked the final presentation video of each below.

The reminder of this page is as it was in the run up to the event


At what will be our milestone 25th hack weekend we will be looking at what is involved in creating and sharing products openly. This might be data, information, images, software code or even hardware.

We’re working with partners and volunteers to create a growing list of possible projects which they would love you to work on with them. Or you can bring your own challenges that you would like to work on.

Whichever route you go down, the determining factor is openness – open licensing, transparency, sharing and re-use.

While we’d hoped to make this a physical / virtual hybrid, for reasons out of our control we’ve had to make it virtual only. We’re sure our next one will be physical too!

Challenges and projects

We’re working on a final list of challenges and projects which we will keep updating in this Google doc.

So far we have

As part of the event we will be running a Wikipedia Editathon – with training and practice in creating, and improving Wikipedia articles. This will be facilitated by Wikimedia UK’s Scotland Coordinator, Dr Sara Thomas and our own Ian Watt. This is likely to overlap with and support several of the items on the list above.


We’re working on finalising the exact format but the weekend will resemble this:

By signing up for this hack weekend, you agree to our Code Of Conduct

Who should attend?

Anyone – despite our name, coding is a small bit of what we do.

Of course, coders, data wranglers, designers and other techies are important to a hack weekend.


As a charity we aim to encourage all to attend our events – and to make the barrier to attendance as low as we can make it. We also have to consider our costs of administration. So our standard tickets are just £5 for the weekend.

If this is a barrier to you attending please get in touch and we can issue you with a ticket at no cost, no questions asked.
