[Andrew Craig @andrew_cb2]

Great and wide-ranging discussion about symbols (represented by languages like APL) vs words (represented by languages like q) in array languages.

[Arraycast @arraycast]

The plan was to talk about tacit programming, but we never got around to it. Instead we found naming things is one of the hard problems of computing.

Host: @code_report

Panel: Marshall Lochbaum, Adám Brudzewsky, Stephen Taylor and Bob Therriault.

@TheAviralGoel @tritlo Thanks!

[Andrew Craig @andrew_cb2]

@TheAviralGoel @tritlo What does 'DU' stand for?

[Andrew Craig @andrew_cb2]

@backtobourbon @matsonj @kennedymwavu @JosiahParry Yep, it's built into the REditorSupport R extension. Ctrl+Enter by default. https://t.co/y5XR85Ef0N

@adspthepodcast @SeanParent @jeriellsworth @tiltfive I love these Sean Parent episodes.

Advent of Code 2023 Day 7 (part 1) comparison between (Dyalog) #APL, #Kap, and base #rstats https://t.co/oEOH4tuvRV -- in which I detail an elegant array solution.

I'm all in for learning the APL glyphs, now!

New post: Hooray, Array! https://t.co/kDPehsWak6 in which I try out the new stack-based array language Uiua

Open challenge to @code_report (or anyone) to improve on my solution(s).

New post: Now You're Thinking with Arrays

in which I realise that I got into programming while exclusively learning languages with something interesting in common.

[Andrew Craig @andrew_cb2]

@carroll_jono @code_report Absolutely! I learnt MATLAB in uni as well and then worked with R so the arrays in APL and friends have felt very familiar. I think it's because of that that the most exciting part of APL for me has been the combinator features like the fork and ⍥.

@adspthepodcast For the outer product applying any function it's the built-in outer().

[Andrew Craig @andrew_cb2]

@adspthepodcast My two favourite languages are R and q so I was happy to hear R discussed even if not very positively! In R's defense, the built-in pipe is |> and the built-in outer product is %o%. I agree that it would have been nice to have had a separate scan function.

[Andrew Craig @andrew_cb2]

@dirk_sch Fortunately I wrote a short article about that a couple of months ago 😀

[Andrew Craig @andrew_cb2]

I wrote a short article about q, a language that's surprisingly similar to #rstats (built-in data frames etc.).

@dirk_sch I don't know a lot about go but that does sound interesting!

[Andrew Craig @andrew_cb2]

@dirk_sch It's a language that goes along with the kdb+ database. It's unfortunately not open source but does have a lot of nice features. Here's some example code: https://t.co/b2CP20HtHy

[Dirk Schumacher 🚲 @dirk_sch]

Say you write an R interpreter from scratch and you allow yourself to make breaking changes. What would you break and what would you keep? #rstats

[Andrew Craig @andrew_cb2]

Some dataframe history: 'Statistical Models in S' (1991) is the book that first mentions dataframes. From Monday Morning Data Chat podcast episode 135: Dataframe Deep Dive w/ Devin Petersohn. https://t.co/KYdcehIk4C
