Pondering Axum + F# by podwysocki

It’s been a while since I’ve posted about Axum as I’ve been posting about other asynchronous and parallel programming models. After two releases of the Axum standalone language and lots of good user feedback, it’s time to ponder what could be with Axum...

F# – Async Running with Continuation Scissors by podwysocki

As you may have noticed, I’ve been covering a bit about concurrency on this blog lately, and for good reason. Between Axum, Erlang, Scala and F#, there is a lot to explore with actor model concurrency, task based concurrency, data parallel applications...

Axum – Ping Pong with Ordered Interaction Points by podwysocki

UPDATE: Removed code and explained that what I had was not intended behavior After a slight diversion into F# mailbox processing, it’s time to come back to talk a little bit more about Axum . In our last Axum post , we discussed using dataflow networks...

When Side Effects and Laziness Collide by podwysocki

While working on a side project recently, I came to rediscover some of the consequences of one of my earlier posts on “Side Effects and Functional Programming” . It’s important that we realize that when we are creating our programs to beware of lazy evaluation...

Actors in F# – The Bounded Buffer Problem by podwysocki

In the previous post , I covered an example of an auction simulation using asynchronous message passing and a shared nothing approach using the MailboxProcessor class in F#. The auction example was a great piece to demonstrate scalability by adding additional...

F# Actors Revisited by podwysocki

UPDATE: Removed ref cells to use two recursive loops In the previous post , I covered briefly about the actor model in F#. This style of concurrency, using asynchronous message passing and a shared-nothing approach through the use of mailboxes is a pretty...

Axum – Ping Pong with Dataflow Networks by podwysocki

In the previous post , I gave the canonical Ping-Pong example in Axum and how it compared with Axum. I want to revisit this post because there are some areas in which we can rework it in addition to the other solutions we’ll visit. Some parts were needlessly...

Talking Functional Programming with Erik Meijer by podwysocki

When I was last out in Redmond, I had the opportunity to sit down with Erik Meijer to speak about something for which I’m passionate, functional programming. After such recent appearances on Channel9 as Joe Duffy and Anders Hejlsberg , I was quite flattered...

Which Is More Beautiful Architecture - FP or OOP? by podwysocki

Recently, upon the recommendations of a few people, I picked up a copy of the book “Beautiful Architecture: Leading Thinkers Reveal the Hidden Beauty in Software”. This book is a great read and includes essays from some of the top minds in software today...

Exploring MapReduce with F# by podwysocki

With my exploration into mass concurrency and big data problems, I’m always finding challenges to give myself on how I might solve a given issue. Such examples that have intrigued me along the way as PLINQ , MPI/.NET , Data Parallel Haskell , but one...
