Simple Parallel Array Filtering in F#

Recently I was doing some data processing and since it fit nicely in a parallel setup, I changed my pipeline to use the Array.Parallel module. An easy and simple change that can speed up your task especially if it’s time consuming. Nonetheless, I also needed Array.filter and to my surprise it wasn’t available in the … Continue reading Simple Parallel Array Filtering in F#

Articles about using F# to implement Lisp

I was looking for examples of Lisp implementations using F# and found these 3 interesting series of blog posts. You can find other posts about implementing Lisp or Scheme using F# but these were the ones I found more comprehensive and different enough to compare different implementations. Although these Lisp implementations are learning experiments and … Continue reading Articles about using F# to implement Lisp

A note on shortcircuiting of argument evaluation in #'<

There is an interesting thread in the Clozure Common Lisp development mailing list about argument evaluation in #'<. Until now, CCL was implementing shortcircuiting when evaluating the arguments of #'<. This essentially means that when calling (< 1 3 2 4 5) it would stop before evaluating all the arguments since it wold know it … Continue reading A note on shortcircuiting of argument evaluation in #'<

Professional Change

After many years in academia doing research, I’ve recently joined the software industry. I am now working at Microsoft, specifically, at their Search Technology Center in Munich. It’s an exciting and challenging work! I will continue doing my Common Lisp explorations in my free time and talk about them in here as before (disclaimer: the … Continue reading Professional Change

zsort: portable sorting algorithms in Common Lisp

zsort is a library that I started working on as a simple hobby project. More or less around the same time I decided to check which algorithms the different Common Lisp implementations use. It is now part of Quicklisp so it can be easily used (thanks Zack!). The main goal of zsort is to be … Continue reading zsort: portable sorting algorithms in Common Lisp
