I don’t think I have any special strategies, although I typically use syntax-debug-info to check scopes and get a sense of what’s going on

Hi everyone, I just saw a tweet about the PhD application deadline at NEU PRL in about 2 weeks.

I want to apply and was hoping to get some insight into the college before committing.

My background is very technical — math and CS — but my interests and strengths seem to fall at the intersection of technical and non-technical.

My Masters project applied results from sociology and political science to designing, building, and operating scalable ad hoc decentralized systems.

My advisor was supportive, but could not get involved. He did not share my research interests and had PhD students to manage.

Would I run into similar obstacles at NEU, particularly in the PRL?

@dedbox I would encourage you to contact people specifically that you might be interested in working with there

@samth ok, thanks.

Does anyone here use / prefer typed Racket?

use

ah I just read it seems not to perform well with the rest of the ecosystem

that is unfortunate

@slack1 dunno if the videos for oopsla/splash are up yet, but @samth gave a good talk on that

(and a couple other related talks)

It does, in many cases, perform just fine

Some times you’ll have to move an extra module to typed racket

And that talk is already up on YouTube

Heard about this from a podcast (Magic Read Along) today. It’s a web-based IDE inspired by, and geared towards Haskell, Lisp/Racket, Scala, etc.

I heard about an interesting kind of compose that takes a kind of function like map or filter, and doesn’t produce the intermediate data structures

I wonder if Racket does those kinds of optimizations under the hood

@slack1 that’s usually called “deforestation” or “stream fusion”

and Racket doesn’t do that automatically

ah I see, so it’s beneficial to write one

(it’s quite hard unless your language is like Haskell — lazy and pure)

I’m surprised to see that talk of this idea is like over 10 years old

yeah, it’s quite old in functional languages, probably older when considering arrays

the first paper on deforestation was written 30 years ago

other papers on related topics are older

Hello all :wave::skin-tone–5: Where is the best place to find help for slideshow?

right here

Good :blush:. Let’s start with the easy one. How do I move the presentation to the second screen? I used it yesterday for a dry run , and couldn’t make it move to the proyector screen, so ended mirroring the display (which meant couldn’t have the comments and the next slide views available)
