The microservice architectural style provides development teams with a more decentralized approach to building software, each service being isolated, built, deployed, and managed independently. As a consequence, containers have become the de-facto consistent and resource-efficient standard of packaging individual services. Then came the emergence of orchestration tools such as Docker Swarm, Kubernetes, and Nomad. These tools help with automating scaling, deployment, and container management.

Although microservices-management complexity is dwindling due to these breakthroughs, some challenges remain, like the smooth and easy monitoring of such infrastructures. For instance, the ELK stack is typically used to address this need. …

A smart person isn’t just a high IQ, although IQ has evolved to include many more abilities than linguistic and logical-mathematical abilities. The smartest people I have encountered in my life share common traits but I argue it is the expression of a single principle they apply (consciously or unconsciously):

Smart people don’t provide answers, they ask questions

The next point to tackle is the following: why do they prefer asking questions instead of demonstrating their knowledge? Indeed, research has shown that self-disclosure activates our dopamine pleasure centers. Of course, at some point, they answer questions, but it seems to…

In response to this unprecedented crisis, many people and activities turned to digital tools to keep some semblance of normality. In my humble opinion we have a mixed set of results in France and here are some insights about it. More specifically, a fast and forced adoption of digital tools with insufficient leadership has left many confused about what technology can do to help. In addition, the half-heartedness of governmental actors and major industry players to embrace openness and transparency has made this situation worse, while trust is probably our best asset at the moment.

This is probably one of…

Preamble

At Kalisio, we develop open-source geospatial software — that’s to say, software that manages geolocated assets but in a more friendly and business-oriented way than GISs usually provide. We’ve built a strong ecosystem composed of various tools and applications, providing dozens of web services to deliver our solutions as SaaS:

• Kaabah, a solution to build and operate Docker Swarm infrastructures
• Kargo, a Docker-based solution to deploy geospatial services
• Krawler, a minimalist extract-transform-load (ETL) tool
• Weacast, a platform to gather, expose, and make use of weather forecast data
• KDK, a development kit to simplify building geospatial web applications
• Kano, a map…

Preambule

From the point of view of some folks your job can always be seen as bulls**t at a certain level. To take an extreme example anything but rural peasantry was probably seen as bulls**t by the Khmer Rouge regime. The fact is that the value of a job, its usefulness to society, is a pure human construction. As a consequence it cannot be a matter of discussion. …

Introduction to service mocking

FeathersJS provides a common query syntax, which is a subset of the MongoDB query syntax, on top of its unified service interface out of the box. Any database adapter complies with it and has the same interface as the other adapters. This is really good news because if you’d like to unit test your service you can easily mock it up by using the feathers-memory adapter instead of your actual DB adapter. Indeed, it is usually a better strategy for at least three key reasons:

• it avoids the headache of running a DB in your test setup,
• it is more…

A une époque où l’on cherche à protéger notre savoir-faire artisanal et local face à l’externalisation, et à la vue de l’importance que prend le numérique dans nos vies, je déplore que peu de personnes intègrent le développement de logiciels dans ce mouvement. Je pense que cela est principalement lié à la méconnaissance profonde de ce métier par le grand public, alors même que l’informatique est aujourd’hui reconnue comme une “technologie d’application générale”, c’est à dire provoquant des changements structurels dans la plupart des sphères de la société.

Le développement de logiciels est une activité artisanale dans le sens où…

You might be aware of Geographic Information System (GIS) designed to store, retrieve, manage, display, and analyze all types of geographic and spatial data.
