Object oriented programming in Ada
I never understood object-oriented programming until I learned Ada. A friend was curious about what I meant by that, so tried to get me to translate some Java code into Ada. That didn't end up being very illustrative, but we touch on classes, encapsulation, inheritance, and memory management; it might tickle your curiosity!

Getting to know you
Over the past few weeks I've asked you some questions, and this is the last question I have planned for now.
What is your gender? (If you prefer not to say, simply do not answer)
The answer to this question may help me interpret other questions, but it's also fun to know my demographics!
Flashcard of the week
I ended up reading a bit of Boyd recently to finally try to understand how his OODA loops are different from the Shewhart plan–do-study–act cycle. I won't explain too much about this here because it will become a full future article later.
Which are the three aspects of Boyd's OODA loops that aren't captured by the Shewhart cycle?
There is one way, a surface reading, in which the OODA loop is exactly a Shewhart cycle, but then it implicitly encompasses three more aspects, unlike the Shewhart cycle.
(1) Temporality, (2) Organisational shape, and (3) Interactive loops of different sizes.
The OODA loop cares about when in time each step happens. It cares about how an organisation is shaped to maximise adaptation from the OODA loop. Any organisation also runs multiple intersecting OODA loops of various sizes, and these need to be arranged so they harmonise.
