Yup, we're Heatherless again. We promise you Heather next episode.
Join us during (and between) episodes for web-based Scalawags chat on Gitter.
- our amateur beatboxing is not improving
- Daniel's brain is all better now
- but hear him tell the story of the cat, the clothesline, and his emergency room visit
- demoing his terminal application that renders your webcam live in ASCII art, using Akka streams
- what, no speech bubbles? alas, audio-on-the-JVM
- hi, we're the Scalawags
- Scala Days: all five of us were there together, and Lukas took a photo, but we didn't have time to do an episode
- nostalgia for the modem yodel
- all the talk videos are at https://www.parleys.com/channel/scala-days-san-francisco-2015
- we liked the "go change the world" keynotes by Danese Cooper and Dianne Marsh
- Dick reveals which parts of his intro of Danese were actually outrageous lies
- bombshells in Martin's keynote? well, Hascalator. don't forget Hascalator.
- more details on TASTy (Martin's proposal for delivering Scala libraries not as JARs, but as Typed Abstract Syntax Trees). but don't hold your breath
- bit at the end of Martin's keynote about representing effects in the type system, because monad transformers make everyone's heads explode
- or do they? discuss.
- try to unify subtyping and parametric polymorphism and all hell breaks loose
- new Typesafe proposal to speed up the Scala compiler by replacing it with Mechanical Turk
- Daniel liked Andrew Phillips' Scala Puzzlers talk
- https://www.parleys.com/tutorial/scala-puzzlers-matrix-anything-possible
- Daniel got a lot of them wrong, and so did Adriaan and Miles
- Dick liked Julie Pitt's "If I Only Had a Brain... In Scala"
- Dick has seen Brendan McAdams's "A Skeptic's Look at scalaz' "Gateway Drugs"" talk before and liked it
- Functional Reactive Programming, what it is or isn't, and how Josh wrote an ASCII Pong game with it, but with only one paddle and no ball
- Josh's effort at a beginner talk, on Scala libraries newcomers should know about. sharing the ecosystem lore
- Daniel: there'll never be a complete reference; people should just ask on IRC or Gitter
- or it could be like apps: "Enjoying Scalaz? Give us a five-star review!"
- beginner, intermediate, or advanced?
- Seth liked Joe Barnes' Type-level Programming in Scala 101"
talk
- https://www.parleys.com/tutorial/type-level-programming-scala-101
- advanced topic, beginner-friendly presentation. so what is it, beginner or advanced?
- why didn't your talk get in?
- there were a ton of submissions
- everyone sent "reactive" proposals
- everyone's proposals were "intermediate"
- your abstract was way too long
- your abstract was way too short
- who are you? you had no bio
- Josh thinks you're a jerk
- Seth liked Chris Vogt's "Compossible: Extensible Records and
Type-Indexed Maps"
- https://www.parleys.com/tutorial/scala-records-extensible-records-type-indexed-maps
- giving the type system a more flexible idea of what fields are present in data
- Seth liked Miles Sabin's talk on automatic derivation of typeclass instances
- https://www.parleys.com/tutorial/swiss-army-knife-generic-programming-shapeless-typeclass-type-class-action
- look ma, no macros! well, one shared behind-the-scenes macro, but the new stuff is all implicits built over it
- don't macro everything. what should you macro?
- TASTy: are macros expanded, in the trees?
- Daniel liked Vlad Ureche's miniboxing talk, "Project Valhalla: The Good, the Bad and the Ugly"
- https://www.parleys.com/tutorial/project-valhalla-the-good-bad-ugly
- that's "oo-ray-kay", more or less, but call him Vlad
- Project Valhalla involves bringing something like specialization to the JVM so Java can use it. but Scala should use it too. we want to write abstract code and have it run fast even for primitive types.
- Scala Days had killer wi-fi
- Scala Days Amsterdam coming up
- Escalate training coming up
- S'mores and type lambdas!
- Tweet your Phil Bagwell Award nominations to @scaladays
- no Typesafers, no EPFL-ers
- the SLIP (Scala Library Improvement Process) committee
had their first monthly meeting
- SLIP talk now on Gitter at https://gitter.im/scala/slip
- Josh selects self, highlights self
- sock puppet pantomime preview of episode #30
After publishing a YouTube video, you can right-click on a timecode, then select "Copy video URL at current time". You get a link that opens the video to that spot, like this: https://www.youtube.com/watch?v=r-QSTPOKyDM&feature=player_detailpage#t=1758 That would allow you to post better links in the gist.
Also, if you past in the timecodes into the YouTube description, one per line, you can write comments next to each timecode. That becomes a clickable table of contents.
