DDD Scotland summary

My takeaways from the conference

BigCode transforming

• The code is a liability, not an asset.
• Refactoring is expensive.
• Everybody in a team should be able to draw an architecture of project!
• Have an architect in a team. Without the architect, it is hard to be consistent with design or you will end up with lack of any design.
• Don’t afraid to kill code. It’s easy to do when you have decoupled code.
• We are heading to the services.

Teaching an old dog new tricks – presentation

• “We cannot be agile if our code sucks” – Venkat Subramaniam
• Recommended video about SOLID principles which is worth watching: Solid principles on example of guitar amplifier

Beyond C# 7

 

• Span<T> “is a new type to represent contiguous regions of arbitrary memory, with performance characteristics on par with T[]”
  • Jared Parsons on channel 9 about Span<T>
  • Github readme about Span<T>
• Other useful concepts:
  • reference assemblies are used at compile time only,
  • reference semantics with value type

Developing for privacy and data protection

• https://webdevlaw.uk/data-protection-gdpr/
• GDPR  applies to all data collected processed and retained about people within the European Union. It concerns personal data and sensitive personal data.
• This law is extraterritorial – it means that GDPR will apply not only in Europe!
• In brief: in EU data belongs to the subject.
• The seven principles of privacy by design:
  • Proactive
  • Default
  • Built into design
  • Positive sum
  • End-to-end
  • Open
  • User-centric
• You should document your approach to protect the user data
• If data leaks you will need to prove that you did what you can to protect the user data.

Adding a layer of chocolate(y) – presentation

• Under the hood, there is PowerShell and NuGet.
• You can improve default installer by adding in chocolatey for example path to the program in the system variable
• Chocolatey has the default implementation of uninstalling feature, so even if your installer doesn’t provide uninstall feature, choco will know how to do it.
• Chocolatey cannot detect reboot requirement
• ‘choco list -lo’
  • Lists all apps installed by choco
  • Synchronise removed apps from “programs&features”.
