  • Jan 14 - Spacemacs Useful Buffers Gotcha

    I’ve ran into a little spacemacs annoyance that took me a while to resolve, and it seems like it could pop up under a variety of different contexts. I figured that a few words about it here might save others some time.

  • Dec 23 - Pretty Printing a Table in Emacs

    Recently, I needed to output some relatively small tabular data in Emacs and message was starting to be a bit long in the tooth. Finally, I’ve decided to try my hand at upgrading the visuals for myself. I realize that there’s probably dozens of different ways of pretty-printing tables in Emacs, but I was already partial to the tabular output used by functions such as list-processes and plugins such as prodigy (Using org mode’s tables also comes to mind for example). So I’ve decided to recreate this experience for my own tables. The result has been convenient and aesthetically pleasing enough to share.

  • Jul 22 - Free Monads in the Wild - OCaml Edition

    OCaml programmers don’t seem to resort to free monads much. I like to imagine that this is the case because we’re a practical bunch. But it could simply be that this technique like other monads is a bit heavyweight syntactically, let alone the performance implications it might have.

  • Feb 26 - Publishing an OPAM Package - a Checklist

    The process of publishing an opam package has come a long way from its modest beginnings. Nevertheless the opam team deserves praise for choosing an extremely simple and flexible model for contribution - the git commit. To me that explains how it aged gracefully with improvements such as:

  • Feb 15 - Scrap your Camlp4

    ppx has been out for a while but it seems like the community has been taking its time transitioning away from camlp4. There’s probably a couple of reasons for that:

  • Jan 06 - Omegle in N2O

    Recently I’ve been messing around with a new and exciting web framework in erlang called N2O. This framework appeals to me for a few reasons. These include:

  • Dec 13 - Type Safe Routing - Baby Steps

    Type safe routing means different things to different people. So let’s start by clarifying the intended meaning in this post. There are 2 widely used definitions:

  • Dec 11 - Abandoning Async

    There is an old and great schism in the OCaml community. The schism is between two concurrency libraries - Async and Lwt. As usual for these things, the two are very similar, and outsiders would wonder what the big deal is about. The fundamental problem of course is that they’re mutually incompatible. The result of this is a split OCaml world with almost no interoperability, and duplication of efforts.

  • May 23 - Introducing Humane-re

    OCaml is my favorite language, but one area where it (its tools rather) often falls short in practice is common string handling tasks where regular expressions are often involved. The kind of stuff that Awk and and scripting languages often get praised for. In other words, not getting in the way and allowing to get the job done with minimal boilerplate.

  • Apr 11 - Middleware in Opium

    In my previous post I’ve introduced opium in a beginner friendly way, while in this post I’ll try to show something that’s a little more interesting to experienced OCaml programmers or those are well versed with protocols such as Rack, WSGI, Ring, from Ruby, Python, Clojure respectively.
