Join us during and between episodes for web-based Scalawags chat on Gitter.
- Seth is out wardriving
- Daniel can't believe this nonsense
- Dick's hotel room is well stocked with English bitter
- "Batteries included" distributions
- Why not more than one? EPFL, Typesafe, Typelevel...
- Dick: how about "metapackages" like Ubuntu?
- Seth ventures something which could surely be agreed upon...
- ...which Daniel immediately disagrees with
- Daniel: the standard library is basically a trump card
- Daniel predicts an uprising on Twitter of all three scalaz.IList users
- Heather strokes her luxuriantly flowing beard
- and speaks up for the Scala 9-to-5ers
- and envisions a better universe
- Daniel: you can't win against String. distinction between "protocols" and other things
- Dick still doesn't know what JSON library to recommend to his students
- Seth presses Daniel to take a side. Daniel likes the idea so much, he takes two
- Daniel dubs my-way-or-the-highway "the Guido approach" and compares Scala users to an ant colony
- Dick: how about we all disagree so much that nothing changes in the standard library for three years? is that what you want?
- Daniel invokes Freud:
- can we somehow do something more akin to continuous delivery? not while we're tied to the Scala release cycle
- Heather is the Lorax, she speaks for the enterprise users
- Dick: they can always stick with the old version
- Daniel: enterprises aren't against change, they're against uncertainty and lack of communication
- Heather: surely there is some middle ground here
- Daniel on the importance of communicating around change
- the Linux model: kernel versus distributions
- is the OS model even applicable to languages?
- SBT is designed so you install nothing but a launch script; each project pulls in everything else it needs
- on Gitter, Rob Norris says the Scala standard distribution isn't needed, because "everyone uses SBT"
- but not everyone: open source yes, enterprise no
- Seth: getting a new build tool into a company can actually be harder than getting a new language in
- Dick still doesn't know what JSON library to recommend to his students
- Heather: is that so bad?
- Daniel: can we collect metadata about libraries so we can find them?
- Dick: look out, here come the library hipsters
- how about an SBT plugin for that? Seth is almost surprised it doesn't exist
- people are (understandably) confused about comments. there's the Gitter room, there's the Google Q&A feature, and there's YouTube comments
- let's just use Gitter?
- "run code without thinking about servers"
- Dick has been messing with it and it's "dead simple" and pretty neat
- Scala isn't officially supported, but it works
- Gilt has a plugin that does deployment
- con: startup time
- Dick's Amazon Echo is psychoanalyzing him now
- comparison with Google App Engine
- by Josh and Matthew Farwell
- Josh is away counting his book-writing millions
- released a few weeks ago
- by Denys Shabalin
- https://github.com/densh/scala-offheap
- sun.misc.Unsafe is going away so use this instead
- it's lexically scoped and includes data structures
- when do you really need this?
- Seth has been writing Java and Scala too long if he actually misses manual memory management a little
- digression into object pools and Java 1.1 nostalgia
- more Scalawags coming soon whether you want it or not
