|---|---|---|
| Supler: complex web forms, not so complex | Tomasz Szymański, Adam Warski | 28m |
Supler provides a Scala DSL that serializes form definitions to JSON and a Javascript renderer that builds HTML, runs common checks in the browser and posts… | ||
| Streams on top of Scala | Quentin Adam | 28m |
Compares concrete libraries: Play Iteratees, scalaz-stream, Reactive Streams and Akka Streams, and shows why streaming prevents loading huge bodies into memory… | ||
| Graphs & gremlins | Paweł Dolega | 38m |
Claims that graph databases (using OrientDB, gremlin-scala) let you keep relational features while gaining much faster traversals through index-free adjacency… | ||
| Function-Passing Style Typed, Distributed Functional Programming | Heather Miller | 31m |
Prototype implements a Function-Passing model in Scala using a pickling serializer, Netty for networking, and typed, serializable closures called spores… | ||
| The Mutability Matrix of Pain | Jamie Allen | 27m |
Explains how JVM heap, thread stacks and concurrency primitives map to Java/Scala code and gives concrete rules: locks cause kernel arbitration and cache loss… | ||
| How AKKA helped me to build an almost successful cloud for telco services | Tomasz Kogut | 24m |
Builds a telco cloud by extracting jBPM process definitions and delegating each step to Akka actors that preload untrusted Java components, replacing… | ||
| Fresh from the Oven: Akka gets Typed | Konrad 'ktoso' Malawski | 38m |
Akka ships experimental Akka‑Typed (2.4.x) and Akka‑Streams (1.0‑M1): actors are now defined as explicit behaviors with typed ActorRef envelopes, removing the… | ||
| Probabilistic modelling with Scala | Martin Mauch | 30m |
Demonstrates building Bayesian networks in Scala with Scala + base gala, constructs a student model and a Monty Hall model, and runs concrete inference. Shows… | ||
| Scalar Conference 2015 Summary | Quentin Adam, Paweł Dolega, Heather Miller, Adam Warski, Tomasz Szymański, Radosław Tkaczyk, Jamie Allen, Jon Pretty, Jacek Laskowski, Pawel Szulc, Martin Mauch, Tomasz Kogut, Konrad 'ktoso' Malawski | 03m |
Founded to fill a gap of Eastern Europe lacking a quality Scala conference, the event runs its second edition as free-to-attend with 30-minute talks that pack… | ||
| Delimited dependently | Jon Pretty | 34m |
Scala code uses an imported mode to turn ordinary APIs into checked-exception APIs with almost no call-site syntax, implemented with implicits and type-level… | ||
