Question

For a couple years I keep returning to ideas of composability remix ability coding in small pieces getting to snap them together and apart fluidly like legos and with lots of collaborators This is what excites me about functional programming how it lends itself to abstractions that compose really well However I was recently inspired by < JP Posma> to throw elegant composability out of the window and simply enable coding in the small by appending small programs together and what we came up with is called twittereval The idea is you add the words eval to a tweet s URL and then we evaluate it and all the tweets above it or referenced as JavaScript It s obviously silly but also kinda neat and I thought it would be thought provoking to this community Excited to hear what ideas and suggestions you guys have I d also really love it if anyone tried it out and made anything cool

David Brooks · Answer

just in case you haven t heard of it you probably have check out flow based programming

stevekrouse · Answer

Thanks Quite familiar with that kind of thing I normally refer a similar but slightly different category of things as node and wire programming I m somewhat into it but not really for reasons of modularity amp composability I normally think of node and wire environments as a UI that s an alternative to text so the semantics aren t as relevant

David Brooks · Answer

It does get a bit mixed up with all the similar looking tools out there but Morrison s original idea definitely puts modularity and composability front and center An old school flow based programming program can be put together in text for instance

Oh interesting can you point me to a good resource

guitarvydas · Answer

a I want to know more but I don t use Twitter much Where should I look b Knee jerk thoughts about composition FBP etc lt to come gt

David Brooks · Answer

Sure His Morrison s website is a pretty good primer he also wrote a book about it

guitarvydas · Answer

Most FBP discussion is on discord <https discord gg tTgUa99c> there is too a google group and slack group

guitarvydas · Answer

The secret sauce of composition is independence AKA concurrency ^parallelism I have begun to call it 0D zero dependencies The secret sauce of FBP is concurrency Once you have 0D you can draw diagrams if you wish incl node and wire diagrams Trying to draw diagrams in a sync based paradigm i e just about every existing programming language meets with resistance and eventually hopelessness and bloatware ^parallelism Parallelism is often conflated with concurrency but is only a subset of concurrency Rob Pike s talk Concurrency is not Parallelism It s Better gave me the words for dividing and conquering these concepts

David Brooks · Answer

oh wow I didn t even know about the discord thanks thumbsup all

What do y all do for sandboxing slightly smiling face

David Brooks · Answer

I use NixOS < Kartik Agaram> if that s what you mean

Kartik Agaram · Answer

No my question was for Steve Eval open to the internet is a bit nerve wracking smile

stevekrouse · Answer

It s all client side evaluation

stevekrouse · Answer

You may have to join the Twitter community to see those tweets I didn t think so but things about Twitter communities can be buggy

David Brooks · Answer

I don t have a twitter account and I could see those tweets just fine <https twitter com stevekrouse status 1523449402009948160>

Kartik Agaram · Answer

Oh you re right I can see <https twitter com stevekrouse status 1523441421562236928> when not logged in but not when logged in
