GTD & Things Process

Some David Allen (GTD) and Merlin Mann wisdom (Inbox Zero guy who now makes podcasts)

  • Life is has lots of inboxes, try and move everything to one place
    • i.e.: email to Things inbox, Reminders to Things inbox, your memory to something written down
  • Similarly, make it easy to capture things
    • I use the Quick Entry dialog on macOS and now the Action Button on the iPhone 15 Pro,
    • You'll eventually find yourself doing this all the time
  • For you to trust the process and get the most out of it, you need to do the reviews, otherwise none of this will work

Installing multiple versions of Xcode

When Xcode is upgraded between major versions (for example 14 to 15), the whole compiler toolchain is upgraded along with support for the new platforms targeted. Sometimes this causes problems, like when deprecated APIs are finally removed.

These changes always happen around significant operating system releases, like when a new version of iOS is released towards the end of September. A good short-term solution is to install the old version of Xcode alongside the current one.

  1. Fetch the last Xcode (for example 14.3.1 which is the last before 15) from the Developer Console (you'll need to be signed in with your Apple Developer account): https://developer.apple.com/download/all/?q=xcode%2014
  2. Extract and move it to /Applications, but with a name matching the version, e.g.: Xcode 13.4.1.app
  3. You should now be able to open your project in Xcode and it build successfully again.

Jest: Changing Mocks per Test

I'd been trying to mock react-native-device-info differently per test, so that I could explore setting a more useful User-Agent based on the platform it was running on. But Jest doesn't make doing this particularly very easy, at least not until recently:

Jest 29 and up

We can use [jest.mocked][1] to replace the implementation inside the it:

import { getVersion } from 'react-native-device-info'

Checking for valid MSIX certificates using Visual Studio

Checking a certificate will work is a bit of an awkward one to solve, but a built-in tool will do it:

 PS> Set-Location "C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\Common7\IDE\CommonExtensions\Microsoft\TailoredProjectServices\"
 PS> .\VSCertificateChecker.exe -f "C:\Users\NickCharlton\Documents\Certificates\DevelopmentTesting.pfx" -t msix
The file ALBAIKDevelopmentTesting.pfx is password-protected.
Enter password: ************************

Certificate Details:
        Private Key Found: True

RSpec: Testing ActiveStorage

RSpec: Testing ActiveStorage

Testing file uploads in ActiveStorage is a little awkward. Fortunately, fixtures comes to the rescue and we can provide a file to be passed through to the parameters. This works across model and system/feature specs.

In your factory, you might define it like:

factory :document do
    name { "Example File" }

Domain Driven Design & Event Storming

Domain Driven Design

  • Ubiquitous Language: the language used by everyone to describe the concepts spoken about (so that they are all on the same page)
  • Bounded Context: "a semantic contextual boundary"; within the boundary, each component has a specific meaning and does specific things
  • Domain:
    • Core Domain: the strategic scope which is core to the business/software product
    • Sub-domain: a sub-part of the overall business domain (supporting is ancillary to the core, but worth implementing in-house, whilst generic isn't, e.g.: user invoicing)
  • Domain Event: a record of some significant event occurring in a bounded context, which can be consumed inside the originating bounded context or by other bounded contexts
  • Aggregate/Entity/Data: a high-level type or model (it may be composed of entities and value objects)
  • Command: an operation which causes a domain event
