This is the second part of my write up of the LeadDev London 2024 conference. To read my thoughts on
the talks from day 1, and my overall impression of the conference please read
my previous post. As with that post this is just the summary
of my notes, so will give you a flavour of the talks. This should help you decide if you want to pay for
a digital pass to access the videos, or if enough time has passed to look them up on YouTube or the
LeadDev site.
In the afternoon I attended a workshop by a couple of Google engineers on DORA. I’ve
watched the recording of the talks I missed, so I’ve included my thoughts on those below. My write-up of the workshop
is at the end of this post.
And with that out of the way, on with the talks…

In what is fast becoming an annual tradition I recently switched on my Slack out-of-office, packed up a
bag with plenty of room left for some conference swag, and got on the train to the Barbican for
LeadDev London 2024 (see my review of 2022
day 1 and day 2, and
2023
day 1 and day 2).
As with last year, this is a one-track conference focused on leadership and engineering management, with a
separate one-track conference at the same time, StaffPlus, focused on Staff+ engineers. I only have a ticket
to LeadDev, so I only got to see those talks.

Most teams will have a team meeting on a regular schedule. Once a week,
every two weeks or once a month the team gets together to discuss the
day’s big issues. This can be a difficult meeting because it doesn’t have
a defined agenda, and is open-ended.
Other meetings either drive a project forward, solve a
specific problem or implement a specific process. They might have a
varying agenda, but the overall goal of the meeting is (hopefully) clear,
and there is a point when the meetings will stop. Barring the team disbanding,
this is not true for team meetings.
A common pattern, and one I am certainly guilty of, is asking people
what issues they would like to discuss, and perhaps sharing a few updates
from around the business. When you get to the end of the agenda you just say
“Thanks everyone” and go back to your desks.
The problem with this is that you are encouraging people to just bring
existing problems to the table, and then only if you manage to get the culture
to be non-threatening enough that they feel comfortable with sharing their
issues with the group.

In my earlier post Sustainable Software Development
I talked about how to build software that can be maintained and improved over the long term, and how to run teams that can
work without burning out. In this post, I want to expand on one area of this - how to maintain innovation while using standards
to reduce diversity in your code base.
Snow-flake applications, which have unique characteristics compared to others in your estate, take a significantly outsized amount
of time to maintain. This extra complexity requires specialist knowledge in your developers, and the time taken to context switching
between applications is increased. You also don’t benefit from the economies of scale, where you can apply improvements across many
of your applications simultaneously.
Historically, sharing code across applications would be done through shared libraries, but the modern software development landscape
is more complex and many companies are moving to Platform-as-a-Service models (PaaS). This is where the infrastructure used to run
an application is more than just a server with a CPU, some memory and a disk. Instead, it is a whole ecosystem of APIs, developer tools
and a platform for running code. Whether internally developed, or purchased from an external company, PaaS systems are chosen because
they abstract developers away from much of the drudgery that previously they would have had to work through, but this also constrains
them to only using services provided by the platform.

I’ve previously written about my attempts to get metrics about my house into Prometheus
and to visualise them with Grafana. This project has gone well, and I can measure
everything I want to apart from water usage - please let me know in the comments if you
have a suggestion on how to do that! The one thing that’s missing is a “glanceable”
display. My Grafana dashboards work well when I’m at my computer, but they’re not so great
when cooking in the kitchen.
