Benevolent Dictator for Life.

The informal, slightly tongue-in-cheek title given to a respected individual in the open source development community who sets general directions and makes final calls in certain situations within the scope of a given project. The BDFL is a tacit acknowledgement that communal, consensus-based decision making within the open source community occasionally runs up against obstacles, in which case a single authoritative voice can be useful. That BDFLs survive and flourish in these otherwise anarchistic contexts is attributed to their personal charisma and their reluctance to wield their power except in rare moments.

Of course, a project coordinator cannot really be anything like a dictator in the sense that he or she ultimately cannot enforce a decision, since a project fork is always possible.

Not all, or even most, open source projects have a BDFL.

Note the difference from the historical meaning of benevolent dictator, which is used in a political context.

Back when I lived in upstate new york 

A meaningless, unimpressive, self-serving introduction. An indicator that the story about to be shared will be pointless and dumb.
Back when I lived in upstate new york, I also had to park on the street - on two occasions, we got enough snow, mixed with just the right plowing, that my car was lifted off the ground from so much snow being jammed underneath it.

Sister: This meeting was to discuss the rough draft of my essay, where we discussed the subsidiary questions I added in my rough draft. We also discussed the relationship between my main title and the real-life situations I chose to use in my essay. We discussed the structure of my essay as well, specifically the Math AOK section and how it relates to the contradiction of the title. This second meeting was particularly helpful in discussing the implications of my essay claims and how to apply the title across various areas of knowledge. There were many sections of the essay that could have been cut down in wordiness and the ways of knowing required further and more in-depth analysis.
