LawyermanTM (@lawyerman_ktk) on twitter: "Mass transit systems are a SERVICE. they don't "lose" money, they cost money. These are services, not poorly run business. Framing public services as profit making entities is the worst form propaganda. No one says the military "loses" $8.8 billion/year. Same here"

Poster de la comédie musicale makina "Bernadette Soubarou". Dans la moitié haute, une femme les yeux fermée vaguement habillée en Vierge Marie. Dans la moitié inférieure, une voiture Subaru bleue. La tagline de la comédie musicale est "182 chevaux dans le moteur, 1 seul dieu dans son cœur".

One of the most powerful refactorings is wrapping a primitive in a more meaningful type and then pushing that change through the entire codebase. It finds bugs, dodgy assumptions and adds meaning, which makes work permanently easier for the next dev (which could be you).
