(it does add a bias lower... is part of the normal approx that it gives the occasional impossibly high value to balance out an overall downwards bias?)

@darrenjw
@avibryant Quick question: @jonnylaw and I are writing a paper about functional PP in which we discuss Rainier. How would you like us to cite it?
Avi Bryant
@avibryant
honestly not something I've thought about or have experience with. Bryant et al, and the github URL?
whatever you do there is zero chance of anyone being offended or unhappy.
Darren Wilkinson
@darrenjw
OK, great, thanks. We'll make something up!
Avi Bryant
@avibryant
(Happy to review drafts etc if that’s helpful or appropriate)

@darrenjw
Draft paper on arXiv. Comments welcome (from anyone) - https://arxiv.org/abs/1908.02062

Nice! Who's the intended audience? People familiar with PPL but not FP?
Darren Wilkinson
@darrenjw
Statisticians, basically.
Also, a blog post that is potentially of interest to Rainier types: https://darrenjw.wordpress.com/2019/08/07/write-your-own-general-purpose-monadic-probabilistic-programming-language-from-scratch-in-50-lines-of-scala-code/

hi guys, is there any chance i can compile rainier to javascript using scajajs?
scalajs cannot use reflection and it is single threaded, so async.await does not work either
also java librararies either cannot be used afaik
jhegedus42
@jhegedus42
also , i am trying to compile stan to javascript ... https://github.com/jhegedus42/stan2js not that easy :)
so, if there would be a way to get rainier to compile to javascript, that would be the killer, coz i have no idea about how to develop c++, but i am decent at scala...
also, 20 years ago i wrote sort of like some hmc code in fortran ...
statistical physics exercises/masters/phd
one should use cats nowadays, so i heard
https://typelevel.org/cats/

@jhegedus42
is rainier using cats ?
i like this blog https://darrenjw.wordpress.com/2019/08/07/write-your-own-general-purpose-monadic-probabilistic-programming-language-from-scratch-in-50-lines-of-scala-code/
but the trend is to use cats
it would be a bad architectural decision to not do so, imho, and not build rainier on top of cats ... if one really wants to do proper functional programming and not reinvent the wheel

it does
impressive
i am sold
this is awesome
this is future
omg
super awesome architecture
scalability
powerful language
easy to code
this is gonna be the probabilistic programming of the future
scala is catching on heavily
especially where people need to use their brains to write code...
and functional programming works very well for math minded people
wow, this rainier project is the best i have seen so far ... when it comes to the mcmc zoo...
jhegedus42
@jhegedus42
the rest are dead ends compared to this ... c++ ... difficult, python ... not typesafe ... none of them are scalable ... dont fit into the distributed ecosystem, cannot be used to write DSL-s, not functional ... nightmare to do development ...
R is dead end too ... its not a programming language ...
scala is a sweetspot .. for people who have brains ...
and if you want to do mcmc ... then you most likely have ...
scala is not easy ... BUT extremely powerful ...
and the people who do mcmc can learn it ...
and R and python and C++ cannot catch up anymore ...
combine mathematicians with cats ...
they will be in heaven
this is the future

ok, over and out ... i work on my website project, if rainier can be compiled to javascript, i would be very happy to make some educational demo using it ...
