Running full builds after merging? 🥱: Ship faster with git tree based caching

Christian Gregg says:

Fast deploy pipelines are an important facet of a fast moving engineering team; allowing you to ship smaller, safer units of value to production, faster, and more often.

In this talk we'll be covering how using git tree objects can allow you to run CI less or potentially not at all (in a not scary manner :) after merging your changes into your default branch, allowing you to get straight to deploying! 🚂

In cases where your team can precompile deployment artefacts your changes could make it into production in under 60s. If your team uses Heroku or Buildpacks to deploy your code, I'll point you to some tricks to help you do just that by detaching building and releasing your application to production!

The Browser Environment - A Systems Programmer's Perspective

Eleanor McHugh says:

A quirky introduction to writing realtime web systems with Sinatra as the backend. The highlight will be WebSockets but there'll also be coverage of DOM manipulation, AJAX/fetch, and timer events.

After the formal part of the meeting, if you want to keep on LRUGging a handful of us usually stay on the zoom call for a bit of a chat. It's not quite the same as hanging out together IRL, but it's better than nothing while things remain pandemic-y. If you have some ideas about an alternative approach, then let us know at


Prior to attending you should familiarise yourself with our README paying close attention to the code of conduct which applies to all attendees, even though we are all in our own little bubbles.

Secure your place

Even in a virtual world there are limited places for attending the meeting so you need to register via eventbrite. The link to the zoom meeting will only be sent to registered attendees on the day of the meeting, around about 6pm. Keep an eye out for the email and check your spam just in case.

Do prepare yourself in advance by downloading the zoom client.
