As the number of our new (and old) customers grows, it becomes crucial to use IaC and enjoy all of its benefits like mitigation of human errors, infrastructure (self-)documentation etc. (more…)
What (the hell) was my app doing: First steps with Opentracing and Jaeger
Try to Google a bit and find some blog posts about adoption of microservices, Docker, Kubernetes and other “new” stuff in the traditional environments. Almost every post is like “yeah, microservices are kinda cool, but monitoring and overall observability is very challenging.”
Well, that’s not true anymore. And today I’m gonna show you one important pillar of this shift from “challenging” to “absolutely possible.” Please make some noise for the technology which can’t be missing in your microservice stack – distributed tracing.

What I Don’t Like About React Hooks
There has been a lot of discussions concerning React Hooks on Twitter recently and Dan Abramov is defending them pretty well. But since I have seen the API for the first time I can’t get rid of the feeling that I just don’t like them. Here is my reason why. (more…)
Is Jenkins still the only choice in 2019? What about Gitlab CI?
As we’ve shared in our previous DevOps posts, we mainly use Jenkins for our common CI and CD tasks. Nowadays, Jenkins is still industry standard, there are heaps of resources tutorials and Stackoverflow threads about (almost) every conceivable issue. I’ve written “almost” back there, I know. Well, sometimes you have to dive in to Java code and figure out what the hell that XYZ plugin actually does. And things can get messy. But enough of complaints.
Data Dependencies Management in Redux Based Applications 2/2
The data dependencies management is an important topic for me. Over the years, while working with React, Redux and other libraries from this ecosystem, we developed a few solutions for this problem. Here is our story.
Interacting with the Tezos Blockchain on iOS, Part 2: Tezos Contracts
This tutorial is a follow-up to the part 1 that explained how to work with TezosSwift. If you did not read it and are already familiar with it or just want to skip to the code generation, I think you should be able to follow this tutorial as well, just download the project from part one.
You’ve changed, Slack
Redesigns launch countless waves of hate. That’s an axiom. Every logo change of any more or less known company is welcomed by tons of bitter posts and comments on every social network of the world. Insults on designers, supposedly “witty” memes, attempts to improve the design, listings of human organs that can be seen in new graphics, discoveries of old-time logos from which the new one was obviously copied – just classic. The quality of the redesign doesn’t matter. Twitter will explode even when Spotify changes the shade of green.

Interacting with the Tezos blockchain on iOS: Part 1
Interacting with the Tezos blockchain on an iOS device should be an easy task. With TezosSwift, we at Ackee are working to accomplish that goal. TezosSwift has been built with type-safety in mind and implements most of what you could possibly need for Tezos development on iOS. Parts of this tutorial are also applicable to Keefer Taylor’s TezosKit, a library that TezosSwift is based on.
Typescript: Function composition and recurrent types
While I was working on our toolkit library Desmond I stumbled upon a problem when defining the TypeScript definition for a function pipe.
Cypress – testing web applications with ease
Jest, Mocha and Chai are among the most known tools for React testing (and Javascript in general) of applications. In Ackee we use Jest for unit test and integration testing. However, when it comes to testing more complex functionalities, working with Jest is not always easy. When integrating many application parts in your tests you must often deal with complex setup of a test environment, mocking modules/functions and handling of asynchronous events. That is the reason I decided to try the testing tool Cypress which our colleague Lukáš heard about at the Reactive Meetup in Pardubice and I would like to share my experience in this article.
