| 00:01 | <@ToxicFrog> | kwsn: lua. Go go gadget coroutines. |
| 00:01 | < kwsn> | ha |
| 00:02 | <@ToxicFrog> | Tarinaky: this is actually for a class; the important part is the recursive backtracking, not the sudoku. |
| 00:02 | <@ToxicFrog> | kwsn: so far everything I've done in this course is Just Better with coroutines, which means I can't use Scala for anything :/ |
| 00:02 | < Tarinaky> | ToxicFrog: Why the sadface? |
| 00:03 | <@ToxicFrog> | Tarinaky: because I want more excuses to use Scala because I want more practice with it. |
| 00:03 | <@ToxicFrog> | However, implementing this in scala requires warping it in ways that feel unnatural to work around the lack of coroutines. |
| 00:03 | <@ToxicFrog> | I guess I could use synchronous Actors but that's kind of heavy for what I'm doing. |
| 00:04 | <@ToxicFrog> | ...hmm. |
| 00:04 | | * ToxicFrog ponders how to implement coroutines in terms of Scala Actors |
| 00:06 | <@ToxicFrog> | kwsn: anyways, the course permits the use of any language (with the caveat that if the prof can't run it out of the box on his laptop, you need to bring in yours and demo it). |
| 00:06 | < kwsn> | ah |
| 00:07 | <@ToxicFrog> | However, all of the small projects are of the form "implement an algorithm, or set of related algorithms, with the ability to step through them and observe their state" - last one was a sort algorithm visualizer. |
| 00:08 | <@ToxicFrog> | This naturally lends itself to coroutines (or continuations in general, really) and the only language I'm fluent in that has sufficiently powerful constructs for same is lua. |
| 00:09 | <@ToxicFrog> | Scala has continuations, but they're so limited by the JVM as to be effectively useless for this; Scheme has call/cc but I'm not comfortable enough in Scheme to do homework in it on tight deadlines. |
| 00:12 | | shade_of_cpux is now known as cpux |
| 00:18 | | * ToxicFrog offers kwsn a preserved call stack |
| 00:19 | | * kwsn declines, goes back to touching up her ada program |
| 00:20 | | * Tarinaky isn't quite sure he understands what a coroutine is. |
| 00:21 | < Namegduf> | Tarinaky: A cooperatively scheduled thread, basically. |
| 00:22 | < Namegduf> | Within a program. |
| 00:22 | < Namegduf> | Usually within a single OS thread. |
| 00:23 | <@ToxicFrog> | ^ That. |
| 00:24 | <@ToxicFrog> | It's like a thread in that it has its own stack, but unlike a thread, when you start it, whatever started it pauses; the coroutine runs until it yields, at which point the thread that started it in the first place resumes executing. |
| 00:24 | < Namegduf> | Yeah. |
| 00:25 | < Tarinaky> | I see. |
| 00:25 | < Tarinaky> | I think. |
