What we're about

Organised in partnership by Scott Logic and FINOS, the Open Source London meetup aims to expand contributions to and consumption of open source technologies that support large enterprises in addressing their business challenges.

We wish to encourage everyone to consume and contribute safely to open source software by fostering collaboration in the community around open source solutions and services for large organisations across the economy.

With expert guest speakers and facilitators at each session, you can expect: demos of the latest open source technologies (don’t worry, no pitches!); case study presentations on transformational or enabling projects; investigations of tech, down to the code level; and interactive sessions exploring agile ways of working and how to foster an open source culture.

In the true spirit of openness, this group welcomes people at all levels of experience, from students and undergraduates to senior business leaders, including:

• Senior business leaders and OSS enablers

• Engineering and open source contributors

• DevOps and quality engineering

• Agile Coaches, Scrum Masters and Product Owners

• Risk, Cyber, Audit and Regulators

• Undergraduates, graduates and other students

• Those seeking engineering opportunities

• Open source community and networkers

We look forward to seeing you at our next event.



If you are interested in presenting at one of our meetups or giving a 15-minute lightning talk on an open source project, please message meetup organiser Claire Cocks (https://secure.meetup.com/messages/?new_convo=true&member_id=290323217&name=Claire+Cocks). We particularly welcome talk submissions from women speakers, speakers from ethnic minorities, and speakers from other under-represented groups.



We believe that the open source community should be representative of the wider community, and that we can achieve this by valuing diversity and fostering inclusion.

While we have a long way to go, we want our open source meetup groups to play their part in delivering positive change. We will take an agile, incremental approach to this, reviewing and learning as we go. Planned initiatives in 2021/22 include:

• a commitment to avoid all-white or male-only speaker line-ups at our events, with help from the wider community

• new activities to facilitate inclusive networking, for those who want to network at our events

• investigating the best means of supporting inclusive interactions at our events for those attending online

We will collaborate with you and ask for your feedback on these initiatives. We will also be encouraging you to share anonymous diversity data with us. This is to help us set a baseline, target our efforts, and measure change over time as we work to make our meetup events as diverse, equitable and inclusive as they can be.

Our Open Source meetup groups have been awarded the Gold badge by CHAOSS. The event badging initiative measures the inclusivity of different technical events through human reviews. You can find out more about the initiative here https://chaoss.community/diversity-and-inclusion-badging/

Open Source London // Sept 2021 // Live stream

Online event

// Why is this a live stream event? //

In September, we'll be hosting our first in-person Open Source Leeds meetup and live streaming the event so that members of our Open Source meetups in Edinburgh, Bristol and London can participate.

This is the approach we will take from now on as we transition out of the pandemic, keeping a regional flavour by hosting physical events in London, Edinburgh, Bristol and Leeds, and live streaming every event to the network so that you can participate in them wherever you’re based.

There will be opportunities to network with other members online, and to ask questions following each talk.

We have three fantastic speakers lined up for our September event:

• Sukhvinder Panesar, Chief Engineer, Lloyds Banking Group
• Colin Eberhardt, CTO, Scott Logic
• James Robertson, Software Engineer, Mixcloud

// Open Source Contribution in Banking // Sukhvinder Panesar

Open source can add much value by reducing development costs, enhancing features, fixing bugs more quickly and, most importantly, by reducing reliance on vendors to manage products and tools.

The emergence of Fintech and Challenger banks – which use infrastructure that’s significantly based around open source tools – has provided a pathway for the bigger banks to also use open source effectively by engaging with a global community of talented engineers to build cutting edge products and services.

In this talk, Sukhvinder will discuss different strategies that are being used in banking to adopt open source. Traditionally, banking has huge legacy estates with common operating models around support for suppliers. Open source creates new opportunities to modernise the estate, along with challenges that must be overcome, as Sukhvinder will explain.

// Open Source Sustainability and our Corporate Social Responsibility // Colin Eberhardt

Modern software is increasingly complex, made up of hundreds or thousands of open source components, hidden away in deeply nested dependency trees. Just how much do we know about these open source components that are an integral part of our products? What are the risks associated with their usage, and our exposure?

In this talk, Colin will take a closer look at the make-up of modern software supply chains – we’ll look at where this code comes from, who authored it and how it is distributed – ultimately asking ourselves the question, “Is this sustainable?”

This problem is growing; to solve it, we need a reset in how we view this precious and fragile asset. Grass-roots activism can only go so far; to really make a difference, large corporations need to wake up to their responsibility and make genuine and tangible commitments.

// Lightning talk: Building open source productivity tools // James Robertson

Many engineers spend years building a suite of their own custom productivity tools. Many of these tools have great value to the wider community and are projects ripe to be open-sourced.

In this talk, James will chart his attempts to open-source some of his own bespoke tools. He will cover the challenges of converting projects to work beyond personal use. He will also cover learning and building in public and his attempts to get traction for the projects. He'll demo his latest tool which allows engineers to keep across all company communications without leaving the comfort of their coding environment.

Open Source London is organised in partnership by Scott Logic and FINOS.
