Hi folks, I just posted a conjecture on mathoverflow https://t.co/YaM13KPy0a

Just added a few extra chapters to my programming course https://t.co/ggg6I6N50g

@headinthebox Although I love category theory, I think that any programming language allowing to somehow write fix(f) = f(fix(f)) while passing a parameter along can do the stuff formally explained.

[Luc Duponcheel @LucDup]

@headinthebox Keep on doing marvelous work, Erik.

@haskellhutt @shwestrick Does Haskell not have an Actor based messaging library? If so, then writing an high level API for parallel programming on top of it should be easy. I did it in Scala.

@runarorama A monad is like an expression. It is compositional. But, while evaluating it side effects may happen.

[Luc Duponcheel @LucDup]

@paul_snively FWIW, transformations and actions are ( almost ) equally important as compositions.

@satnam6502 Miranda was my first FP love as well. David Turner my first FP hero.

adding places

[Luc Duponcheel @LucDup]

I have cleaned up my GitHub accounts and now I have only one
https://t.co/d64w3wTn9d
with three repositories:
theMatrix, yoneda and time-hybrids.

My most important repository, psbp, is under revision.

... but there are only 24 hours in a day ... .

All comments are welcome.

@haskellhutt Enjoy!

[Luc Duponcheel @LucDup]

@octonato @Devoxx Congratulations

@ChShersh Are you 100% sure? I have had a similar experience a few times. Now I just am patient enough.

[Luc Duponcheel @LucDup]

@rockthejvm Some unifying remark instead of a separating one. Scala, running on the JVM and capable of using Java code, has been, more than Haskell, an inspiration for Java language designers, and still is an inspiration.

[Luc Duponcheel @LucDup]

Just created

The repo is about the Time Hybrids book of Fred Van Oystaeyen. Fred is a mathematician, among others outstanding in such fields as noncommutative algebraic geometry, virtual topology and functor geometry.

Added a screencastYoneda repository to GitHub with the code of the screencast and a https://t.co/tyAQ0J5XPA file explaining it.
