Transcendicant:
One who dedicates their life to continuous, incremental all-self-improvement
* To seek the highest state of self freedom
* To grow resilient enough to hold and learn from all experience: the undesired, the shameful, the confused
* To sit in the discomfort of ultimate uncertainty, incompleteness, wrongness and unknowing
* To observe shame as the instinct to hide one's wrongness from others and self
* To discern and accept the utility of self-stories, ego-delusion and social programming, the useful illusions
* To continously renew the facts and data of being and re-tell only the smallest story necessary to act in the world
* To discard unneeded illusions and imagine beyond today's useful illusions
* To create new ways of thinking, new ways of being, new useful illusions

"Finally! Tagless and Fancy Free Monads"
In this talk, we'll explore "final tagless" as an alternative to the free monad.
At the end of this talk, you'll know:
* How to write Scala "final tagless" languages, bridges and interperters
* If monads are evil and the work of "he who shall not be named"
* The pros and cons between the free monad and "final tagless"
* Some suggestions on when to use the free monad or "final tagless"
View lance_bio.txt
Lance is a professional Scala adventurer, open source loner, longevity nut and semi-regular awkward dancer. Lance has been exploring Scala for the last 6 years and recently renewed his Scala vows on his Scala-versary: "I'll never quit you... not like those others". Lance enjoys polishing his shiny sword of functional programming +2 but finds his patrons prefer just "getting things done" with their rusty daggers. Lance also used to do a lot of improv, has deep thoughts about one-handed typing and will win, eventually, by living longer than everyone else.
You can’t perform that action at this time.
