Meditation

It's practically an all-purpose training of the mind.

Meditation has the objects of stable attention and mindfulness (sati in pali), the latter being the optimal interaction between attention and peripheral awareness.

The practice consists in listening to the meditation object (the breath). Whenever you realise the mind wondered off, you happily move back to the meditation object. That's it, everything else are techniques to remove the time you're not following the meditation object.

{}.as_json # {}
{}.to_json # "{}"

# query / command
user_params # query, no get_params etc, prefer queries over commands, leads to more declarative code, which is simpler
remote_document # Query, not get_document, more declarative
buy_document! # Exception to the above, it's probably a POST and I want to express that it's not a free call
prepare_document! # Bang to express imperative behaviour (?)
compact_params(params) # command - takes args and can be reused
compacted_user_params # YES, a noun is better

The Direction Of The Dependency

When projects grow they become hard to change. One aspect that is not often highlighted is dependency direction. I haven't found much material on the topic, maybe the best ideas came from this talk by Sandi Metz "Less, the path to a better design".

Design Patterns

• Value: (read-only) does some math or manipulation with one input value, like a model, but for one value only
• Presenter: (read-only) takes complex data, like different models, and provides extra presentation values, even HTML
• Service: (mainly-write) Has a main method that writes data through delegation, and can expose the results as read-methods (eg: errors)
• Query: (read-only) Joins different models and performs SQL queries on them, ideally through SQL views
• Gateway: (read-write) LIB Wrap of an API (lib: favour primitives, don't depend on app)
• Serializer: (read-only) Converts input to a string like JSON, CSV, PDF blob etc (prefer others)
• Parser: (read-only) convert data from one format to another (prefer others)
• Decorator: (read-only) extends an object with extra value otherwise written in a presenter (prefer others)

Suggestions to a beginner developer

• Be very very humble
• Pick up small and tedious jobs (bug fixes?)
• Understand the product and the user
• Read and fully understand the task
• Think of the best UX, don't compromise
• Think of possible bugs in your code
• Read the stack trace carefully
• Ask for pairings when stuck
