I was invited to the Wroc# conference and here are some of my sketchnotes.
This was a great conference and I have to thank the organisers for inviting me over to sketchnote the conference.
Glenm started by stating the most important thing to consider when it comes to any function or microservice is to think about:
We cannot get anything done without any form of coupling but we want to have LOW COUPLING. Anything that is coupled together we want to be close to each other so that they can easily change together, i.e. we want HIGH COHESION.
Events and Messages are ways of decoupling our systems:
Kim and Sander have an issue with Agile™, how an entire industry has appeared out of a simple set of principles that had helped some early pioneers grow faster. So they decided to create FLOW: The worse software development approach in history which takes a lot of the anti-patterns from other development methodologies.
The current Agile™ practices focus more on certification than real-world practical experiences and so people use the techniques blindly rather than applying the principles.
Let's take a look at the Agile Manifesto again:
That is, while there is value in the items on the right, we value the items on the left more.
Agile™ has grown to focus solely on the left and ignoring the right. It was never about no tools, no processes, no documentation, no contract negotiation and no plan. We still need all of these but not at the expense of the items on the left.

Zan took us through some of the architectural decisions that we might need to make when building a multi-tenant system and how we apply it to building systems on Azure.
This was not about absolutes, but about trade-offs, for every decision that is needed there are multiple possible solutions and Zan gives us a look at the pros and cons of some of those possibilities.

There is a lot about security that I need to think about after this talk. He takes us through some of the interesting attacks that can be made against your site and how you can defend against them.
There is a lot to learn and to try out, but when building up one of the policies we should start bit by bit. We can use the
report-uri to understand what we are missing and what violations may cause our site to break.

Roy made me think a lot about the interactions that I have with people around me, about how I learn and about how I can improve how I can learn.
Being a leader is not always about command and control, a leader should be enabling people, helping them to grow to a position where they do not need you to tell them what to do.
When Roy talks abhout how we learn, he points out that we have points in our abilities jump rapidly, but these jumps tend to be brief and then we "plateau", there are long periods where we don't grow. These jumps are linked to times when we learn something new, we learn a new technique, or a new programming language, where we are taken out of our comfort zone. Being out of our comfort zone pushes you into a ravine where you are less effective, less able, but by going through this process you find the knowledge and skills we need to make the next jump in our abilities.
I came away with several questions, how can I deliberately push myself out of my comfort zone? How can I push myself to learn something new? How can I then do the same for the rest of my team?
One interesting point about team dynamics was that to make a team adapt, the team needs to have the space to adapt. A team exists in one of several states:
Teams can move between these states, so it is important to recognise which state your team is in.
Jacob took us through the world of Xamarin at Microsoft, how we can build cross-platform applications for mobile devises in the .NET world. There is a lot that Xamarin provides, including the ability to test on multiple different devices and even develop for MacOS on the web.
My favourite part of the talk was where Jacob introduced us to Seeing AI, an application that has been built by Microsoft to help narrate the world to blind/partially sighted people. There are so many different features, like being able to read a document, telling the user to rotate their phone to align with the document, or being able to recognise the expressions of faces in a meeting.
Tech like this shows me the potential that exists for the world, technology that is designed to actually make people's lives better, and I hope more apps like this can be made to make the world more accessible.
