The semicircle (episode 8 — The Fifth Floor)

The treatment of error as a source of valuable information is precisely what distinguishes the feedback (error-controlled) system from its less capable predecessors.

Walkthrough: Watch your Ansible deployments in Grafana !

A few months ago our friends Guillaume Lefevre and Etienne Coutaud made an appearance at the 2017 KubeCon to present their work on a monitoring solution based on Prometheus and Grafana. (The video can be found here) A bit over a month later, we faced a problem in production, the platform started to behave abnormally. The graphs showed bursts in metrics which was unusual and some people were wondering if a deployment could have changed something in the configuration and triggered the problem. Even if…

The semicircle (episode 7 — Crisis / Opportunity)

Managers are not confronted with problems that are independent of each other, but with dynamic situations that consist of complex systems of changing problems that interact with each other. I call such situations messes. Problems are extracted from messes by analysis. Managers do not solve problems, they manage messes. Russell Ackoff A chat window opens at the bottom right. Maria: come to see me when you can for 15 minutes today pls. You save your work, answering: I'm coming. You grab something to write with.…

The semicircle (episode 5 — Brownbag Lunch)

Jeremy arrives first, he settles in near the projector and takes a sandwich out of his brown paper lunch bag. "So if I understand correctly, you propose that we spend the lunch break on the XXL code." "Yes. But just experimenting, mind you. It's a trial." "Don't bother justifying, I am joking." Farid and Audrey now show up and take a seat. Farid asks, "Could you remind us what you mean by Mob Programming? I forgot." "Rather than trying to explain it, I suggest we…

Kubernetes vs Swarm: Volumes!

Hey everybody! After reading both the Kubernetes and Docker “How does it work?” series, I guess you can’t wait to transform your old-school infrastructure and put all your applications inside containers. Indeed, containers are a great way to make your applications portable and easy to deploy. Nevertheless, there is a subject we have not discussed yet: data persistence.

The semicircle (episode 4 — Driver/Navigator)

You are late, but it is just getting started. You slip into your chair as quietly as you can. Hardly unnoticed, because the person who is standing near the projector calls you out, asks your name, and explains to you the purpose of tonight's exercise. "We are doing a mob, using TDD, using the Bowling Score kata. That guy," he points to the person who is sitting at the laptop, "he's the Driver. The Driver writes the code, but he doesn't think. You are the…

The semicircle (episode 3 — Communication Breakdown)

The conclusion seems inescapable that at least with certain kinds of large programs, the continued adaption, modification, and correction of errors in them, is essentially dependent on a certain kind of knowledge possessed by a group of programmers who are closely and continuously connected with them. Peter Naur - Programming as Theory Building You look at that bit of code, the one where you have to add some new functionality and hear yourself saying out loud: "I would never have written it this way... How…

WebAssembly, an executable format for the web

With the latest Web browser updates, there is now a standard for high-performance code execution via the Web. WebAssembly is indeed now available on Edge, Safari, Chrome and Firefox. It promises a standard execution environment on all machines, regardless of hardware or OS. Some see in it the future platform for the deployment of universal applications — for mobiles, but not only. A platform that would enable performance very close to that of native applications. Others worry about the upcoming fragmentation of effort and methods…
