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.

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

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)

Agile Manifesto points

People over tools
Sw over doc
Collaboration over contract
Change over plan

Scrumban

Be restful
Put view partials in proper resource (table partial, not table body)
Namespace a lot, use lib a lot, but don't put app (eg AR models) stuff in lib
Models should not use change itself in callbacks; Use services, strategies, queries, have a clear dependency hirarchy
Limit the use of validation (defaults?), they are only for UI purposes, (almost) always add relative DB constraints
DB foreign_keys, unique indexes, null with defaults
No SQL outside of the model
Write extra models (or Query objects?) to connect models
Write non-AR models
