Manipulating YAML and OpenApi specifications with yq

Yq is a powerful command-line tool designed to make working with YAML, JSON, and XML files easier and more efficient. it is build to feell a lot like jq an other popular cli.

YQ functionalities support YAML, making it an invaluable resource for us developers, DevOps engineers, and data enthusiasts who frequently interact with configuration files or structured data formats.

With YQ, you can query, manipulate, and transform data in a concise and expressive way, all while maintaining readability. Whether you're automating workflows, debugging configuration issues, or managing complex infrastructure setups, YQ streamlines these tasks, saving you both time and effort.

Your code-first API needs validation

Image title

When you start a project you might tend to do code first API as this is a well-known territory for most developers, especially with frameworks like Spring Boot which use powerful annotations to generate your API and specifications.

In a matter of a few lines, you have a simple CRUD API up and running. But that’s not the end of the story, people need to consume it next. And as they are looking at consuming your API the first thing they will turn to is your documentation, specification, and associated testing UI.

You would think that the code-first approach and auto-generation of your OpenAPI specification got you covered. Sadly most of the time your specification will be invalid.

Bring your OPC-UA tags to the cloud with AWS IoT and Kepware

Today I would like to introduce you to a set of nice functionalities of both Kepware and AWS.

We all have of favorite OPC server depending on the task, but for me, it is Kepware without a doubt. No, I’m not sponsored, I just love it! The nice thing about OPC servers is usually that they cover way more communication protocols and allow us to connect to otherwise non-OPC compatible machines.

Connecting your on-premises OPC server to the cloud

Now with all these collecting capabilities, we need to be able to store, analyze, and display such data. There is of course some powerful tool to do this such as historians like Osi Pi, but what would be nice is if we could set up as a scalable solution within minutes with unlimited integration and that’s where cloud solution comes handy.

Luckily for us, Kepware got us covered and is already providing an IoT Gateway that will allow us to choose tag which should be forwarded to the cloud.

SiLA 2 going fancy with features

If you have missed the introduction to SiLA 2 please have a look around here: SiLA 2 Hands-on

This will be a more technical article but bear with me as you will gain deeper knowledge about what SiLA 2 is about. I would like to first thank UniteLabs for supporting me in writing this blog series.

Want to skip all the talk and directly see a feature definition? go here

Features! If you should remember one new thing in SiLA 2 I would say that’s it. Features enable you :

to describe your equipment interface precisely to automatically generate the backbone of your server to standardize equipment interface over the industry

What is a feature?

As abstract as this word may be, here we are talking about a well-defined behavior or ability of laboratory equipment. This image above shows all the components of a feature definition.

SiLA 2 hands on : bringing automation to the laboratory

Ever heard about SiLA ? It stands for Standard in Lab Automation, and if you’re not working in automation of life science laboratories, you are probably hearing about this for the first time. In this blog post I will introduce you the benefits of SiLA 2 (the latest version of the standard) and show a hands-on example how the standard can help and simplify laboratory equipment integration into your IT systems.

Let’s set the scene

In a perfect world all your equipment would provide the same way of controlling the functions and accessing the data. Integrating the equipment into your IT landscape would become both consistent and less tedious.

Sadly, until now, several issues may occur :

Real-time OPC-UA tags monitoring in the cloud with AWS IoT

Wouldn’t it be nice to see your field data in (near) real-time? To be able to build a powerful dashboard in a matter of minutes to monitor your process, or start digitizing your visual management practices.
