Talk 12: Jason Hemann

[cgswords]

Love the 10-foot font

[samth]

Use of Racket is implied by the (), you don't have to have it on the slides. :)

[samth]

Syntax highlighting would be nice.

[cgswords]

• We can probably get rid of slide 2...
• Love the fake repl
• Maybe call valof 'eval' for those schemers?

[cgswords]

6 minutes in, we're finishing up background

[samth]

More visuals, less text.

[laurmcarter]

Re syntax highlighting, color distinction between bound variables and quoted data would be nice.

[cgswords]

That bulleted list of the type inferencer, program generator, CL reducer, could make sweet visuals

[laurmcarter]

... or just distinguishing quoted data, for that matter.

[ccshan]

I'm confused about the organization of the introduction. You talk about miniKanren, then microKanren, then back to miniKaren on the next (book cover) slide -- why move back and forth, and more importantly, what is the goal of your talk?

[cgswords]

I feel like this entire constraint discussion could have happened before introducing microkanren.

[ccshan]

For syntax highlighting, you could follow the typesetting of the Reasoned Schemer book?

[cgswords]

Yes, you go through why miniKanren hurts for constraints, and then you could lead into microkanren and talk about adding constraints to it!

[ccshan]

Is the headline "tiny implementation of logic programming now features tiny implementation of constraints"? (Because tiny is teachable) Then put the desiderata slide as FIRST slide.

[cgswords]

:fireworks: ^^^^^^ what ken said

[samth]

Agree 100% with @ccshan and @cgswords.

[samth]

Never use a fixed-width font for text.

[cgswords]

Okay we're getting into the good things, and we're already at 10 minutes (the Constraint Recipe slide). That intro should tighten up.

[samth]

How did the font get so small?

[ccshan]

Maybe one way to demonstrate the pedagogical success of microKanren is to jump right into explaining it (without going through miniKanren - just say that it is too big).

[cgswords]

@ccshan "I'm not even going to bother explaining miniKanren; it's just too big. I'm going to show you some microKanren, and you'll have no problem understanding it" ?

[cgswords]

The syntax-rule could get a nice picture to explain it.

[cgswords]

The same for your call/fresh. A little logic puzzle diagram could be cute? Or some sort of reasoning as we move through the constraints there.

[ccshan]

The claim of "extensible" makes me want a list of extensions that have been made. I assume: booleans (subsuming SAT solver), numbers (subsuming some kind of SMT), etc.

[samth]

Complicated macros on your slide seem unnecessary. Also, why does S0 need to be unhygenic?

[ccshan]

Put "120 lines" claim on the first slide too.

[cgswords]

Using the System, example 1, hits 20 minutes

[cgswords]

Write a pretty-printer, use it, sell it as a front-end?

[samth]

I feel like match could be used usefully somehow in the type inference example.

[cgswords]

@samth are you proposing generating match expanders for mK constraints? Because that's a neat idea.
