- A Worm’s Mind in a Lego Body — the c. elegans worm’s 302 neurons has been sequenced, modelled in open source code, and now hooked up to a Lego robot. It is claimed that the robot behaved in ways that are similar to observed C. elegans. Stimulation of the nose stopped forward motion. Touching the anterior and posterior touch sensors made the robot move forward and back accordingly. Stimulating the food sensor made the robot move forward. There is video.
- Show and Tell: A Neural Image Caption Generator — Google Research paper on generating captions like “Two pizzas sitting on top of a stove top oven” from a photo. Wow.
- Big Data with the ELK Stack — ElasticSearch, logstash, and Kibana. Interesting and powerful combination of tools!
- Apollo: Amazon’s Deployment Engine — Apollo will stripe the rolling update to simultaneously deploy to an equivalent number of hosts in each location. This keeps the fleet balanced and maximizes redundancy in the case of any unexpected events. When the fleet scales up to handle higher load, Apollo automatically installs the latest version of the software on the newly added hosts. Lust.
An argument against the Five Whys and an alternative approach you can apply.
Before I begin this post, let me say that this is intended to be a critique of the Five Whys method, not a criticism of the people who are in favor of using it. This critique I present is hardly original; most of this post is inspired by Todd Conklin, Sidney Dekker, and Nancy Leveson.
The concept of post-hoc explanation (or “postmortems” as they’re commonly known) is, at this point, taken hold in the web engineering and operations domain. I’d love to think that the concepts that we’ve taken from the new view on “human error” are becoming more widely known and that people are looking to explore their own narratives through those lenses.
I think that this is good, because my intent has always been (might always be) to help translate concepts from one domain to another. In order to do this effectively, we need to know also what to discard (or at least inspect critically) from those other domains.
The Five Whys is such an approach that I think we should discard.
A humanist approach to automation.
Editor’s note: At some point, we’ve all read the accounts in newspapers or on blogs that “human error” was responsible for a Twitter outage, or worse, a horrible accident. Automation is often hailed as the heroic answer, poised to eliminate the specter of human error. This guest post from Steven Shorrock, who will be delivering a keynote speech at Velocity in Barcelona, exposes human error as dangerous shorthand. The more nuanced way through involves systems thinking, marrying the complex fabric of humans and the machines we work with every day.
In Kurt Vonnegut’s dystopian novel ‘Player Piano’, automation has replaced most human labour. Anything that can be automated, is automated. Ordinary people have been robbed of their work, and with it purpose, meaning and satisfaction, leaving the managers, scientists and engineers to run the show. Dr Paul Proteus is a top manager-engineer at the head of the Ilium Works. But Proteus, aware of the unfairness of the situation for the people on the other side of the river, becomes disillusioned with society and has a moral awakening. In the penultimate chapter, Paul and his best friend Finnerty, a brilliant young engineer turned rogue-rebel, reminisce sardonically: “If only it weren’t for the people, the goddamned people,” said Finnerty, “always getting tangled up in the machinery. If it weren’t for them, earth would be an engineer’s paradise.”
You need to understand users to create engaging experiences that add value.
“[Jeff Sussna says in his blog post Empathy: The Essence of DevOps]: ‘It’s not about making developers and sysadmins report to the same VP. It’s not about automating all your configuration procedures. It’s not about tipping up a Jenkins server, or running your applications in the cloud, or releasing your code on GitHub. It’s not even about letting your developers deploy their code to a PaaS. The true essence of DevOps is empathy.’
“Understanding the other people that you work with and how you’re going to work together more effectively — that word ‘empathy’ struck me and it made me connect the world of DevOps with the world of user experience design.”
In the design community, empathy is at the heart of delivering excellent user experiences. Read more…
