Exocortex: Setting up Huginn

Sep 11, 2016

In my last post I said that I'd describe in greater detail how to set up the software that I use as the core of my exocortex, called Huginn.

First, you need someplace for the software to live. I'll say up front that you can happily run Huginn on your laptop, desktop workstation, or server so long as it's not running Windows. Huginn is developed under Linux; it might run under one of the BSDs but I've never tried. I don't know if it'll run as expected in MacOSX because I don't have a Mac. If you want to give Huginn a try but you run Windows, I suggest installing VirtualBox and build a quick virtual machine. I recommend sticking with the officially supported distributions and use the latest stable version of Ubuntu Server. At the risk of sounding self-serving, I also suggest using one of my open source Ubuntu hardening sets to lock down the security on your new VM all in one go. If you're feeling adventurous you can get a VPS from a hosting provider like Amazon's AWS or Linode. I run some of my stuff at Digital Ocean and I'm very pleased with their service. If you'd like to give Digital Ocean a try here's my referral link which will give you $10us of credit, and you are not obligated to continue using their service after it's used up. If I didn't like their service (both commercial and customer) that much I wouldn't bother passing it around.

As serious web apps go, Huginn's system requirements aren't very high so you can build a very functional instance without putting a lot of effort or money toward it. You can run Huginn in about one gigabyte of RAM and one CPU, with a relatively small amount of disk space (twenty gigabytes or so, a fairly small amount for servers these days). Digital Ocean's $10us/month droplet (one CPU, one gigabyte of RAM, and 30 gigabytes of storage) is sufficient for experimentation and light use. To really get serious usage out of Huginn you'll need about two gigabytes of RAM to fit multiple worker daemons into memory. I personally use the following specs for all of my Huginn virtual machines: At least two CPUs, 60 gigabytes of disk space, and at least four gigabytes of RAM. Chances are, any physical machine you have on your desk exceeds these requirements so don't worry too much about it (but see these special instructions if you plan on using an ultra-mini machine like the Raspberry Pi). If you build your own virtual machine, take into account these requirements.

Exocortex: Identity and Agency

Sep 05, 2016

Some time ago I was doing a longform series on Exocortex, my cognitive prosthetic system. I left off with some fairly broad and open-ended questions about the implications of such a software system for identity and agency. Before I go on, though, I think I'd better define some terms. Identity is one of those slippery concepts that you think you get until you have to actually talk about it. One possible definition is "the arbitrary boundry one draws between the self and another," or "I am me and you are you." A more technical definition might be "the condition or character as to who a person or what a thing is; the qualities, beliefs, et cetera that distinguish or identify a person or thing." That said, in this context I think that a useful working definition for the word 'identity' might consist of "the arbitrary boundry one draws between the self and another being that may or may not incorporate the integration of tools or other augmentations." Let us further modify the second, technical definition to include "the condition or character as to who a person or what a thing is or consists of due to the presence or absence of augmentations that modify the capabilities and/or attributes thereof," due to the fact that the definition should explicitly take into account the presence or absence of software or hardware augmentations. We also need to examine the definition of the word agency, which seems even more problematic. The Free Dictionary says that one definition is "the condition of being in action or operation," or loosely "being able to do stuff." The Stanford Encyclopedia of Philosophy says (among other things) the following about agency as a concept: The exercise or manifestation of the capacity to act. Of course, there are also arguments about the philosophy of agency that involve actors that should not be capable of having the intention to act doing so anyway, sometimes in ways that are functionally indistinguishable from organic life (which we usually think of as actors in the philosophical sense, anyway). And that's where things start getting tangled up.

Before I move on, I should set up two additional definitions. For the purposes of this post, 'agent' will refer to one of the functional units of Huginn used to construct solutions to larger problems. 'Constructs' will refer to the separate pieces of more complex software that plug into Huginn from outside.

OTR fingerprint page update

Aug 30, 2016

I'll be updating my OTR fingerprint page in a day or so. Please be patient.

Also note that I'm tired of being able to log into the jabber.ccc.de server one time in ten, so consider if officially deprecated.
