A bramble of raspberries

A bramble of raspberries

For the past few months I've been increasingly obsessing over the idea of building a cluster of computers. Partly, to accelerate my learning, understanding, and internalisation of distributed computing [https://en.wikipedia.org/wiki/Distributed_computing]. Partly, to generate some new content to write about here and talk

Journeyman: thoughtbot

thoughtbot [https://thoughtbot.com] is a company that to most Rubyists needs no introduction. Legion are its employees' contributions to the open source ecosystem. My first encounter with thoughbot occurred four years ago when Mike Burns moved to Stockholm and started looking for gigs around Christmas 2011. The following

Stack machine, part 3 - Burst into flames

In the first part [https://codecoupled.org/2015/10/18/stack-machine-part-1] we built a very basic stack-based machine and we introduced the concept of subroutines in the second part [https://codecoupled.org/2015/10/20/stack-machine-part-2]. Halt and catch fire Granting the name to a highly enjoyable TV series [https:

For an excellent writeup in Swedish from the perspective of the MittMedia development team, see Mathias Nylén's blog post [http://dev.mittmedia.se/team/blogging/lennart/2015/11/05/lennarts-journeyman-tour.html] . Satisifed with the last few adjustments to the presentation, I glanced out of the window at the

Virtually Instructional

This is a slightly edited version of the talk I recently gave at ElixirConf 2015 [http://elixirconf.com] and Stockholm Elixir [www.meetup.com/stockholm-elixir/events/223392326]. Below is the recording of that talk, courtesy of Confreaks [http://confreaks.com]. Also, the presentation is available in all its glory [http:

Stack machine, part 2 - Hear me calling

In the previous part of this series [https://codecoupled.org/2015/10/18/stack-machine-part-1], we looked at implementing a very basic stack-based virtual machine [https://en.wikipedia.org/wiki/Stack_machine] in Elixir [http://elixir-lang.org] . At the end of it we began to ponder the concept of functions. But

Stack machine, part 1 - The deleted slide

During my ElixirConf talk [http://confreaks.tv/videos/elixirconf2015-virtually-instructional] I compared and contrasted register-based virtual machines [https://en.wikipedia.org/wiki/Register_machine], like the BEAM, to stack-based virtual machines [https://en.wikipedia.org/wiki/Stack_machine], like the JVM [https://en.wikipedia.org/wiki/Java_virtual_machine]. In doing

Disassembling pattern matching

In my ElixirConf talk [http://confreaks.tv/videos/elixirconf2015-virtually-instructional] I said that pattern matching doesn't work in the magical way that many of us might think it does. As demonstrated in the talk, this is true enough when using guard clauses. But what if we're only

Journeyman: Auctionet

Before becoming an official part of Auctionet [https://auctionet.com], there was a development team known as Barsoom [http://www.barsoom.se]. I've known the team for several years now, even before Kim [https://codecoupled.org/author/kim] joined it in 2012. But since before that they'

For the longest period of time, all I knew was that I had been invited to visit and work with a team by Shadowman [http://megaman.wikia.com/wiki/Shadow_Man]. Well, at least that's his avatar. My Google-fu skills failed me and as much as I tried,

Let me preface this instalment of my journeyman [https://codecoupled.org/2015/05/06/announcing-my-journeymanship] tales by this: if I was living in Gothenburg, I would eagerly spend my working days at Elabs [http://www.elabs.se]. But more importantly, I would want to spend a lot of my free

You, Pia [https://twitter.com/frusunnanbo] said, waving a finger at me as I was sitting next to her waiting for the next lightning talk to begin at Agila Sverige [http://agilasverige.se]. I want to talk to you. Less than a month later I found myself in the halls

Syntax, semantics, and aesthetics

I'm not usually inclined to start a blog post with a tl;dr [https://en.wikipedia.org/wiki/Wikipedia:Too_long;_didn't_read], but if I were, this one's would be a link to Xkcd [https://xkcd.com/386]. Ever since venturing into the

Plugging PlugRequireHeader

Over the last few weeks I've been working on another Elixir [http://elixir-lang.org] Hex package [https://hex.pm] - PlugRequireHeader [https://github.com/DevL/plug_require_header]. While not at 1.0 quite yet, I still would like to share it with you after taking a detour

A mob of mobs

It's been over a year since I last wrote [https://codecoupled.org/2014/03/03/walking-the-walk/] anything about mob programming [http://mobprogramming.org], but time hasn't stood still. At Mag+ [https://magplus.com] we've continued to use mob programming in various ways and contexts;

And good times were had by all

A few weeks ago my friend and colleague Martin Svalin and I paired on an experimental Elixir [http://elixir-lang.org] application, implementing the forward portion of the store and forward pattern [http://en.wikipedia.org/wiki/Store_and_forward]. In doing so, we wrote three very small date and time
