Deploying a WebAssembly smart contract on Oasis Ethereum

One of the cornerstones of Ethereum 2.0 is the migration from the “classic” EVM to a WebAssembly-based virtual machine. In this post, I explain how to deploy a compiled WebAssembly contract to the Oasis Ethereum chain.

Innovation in the web without sacrificing accessibility

We’ve truly stretched the boundaries of what is possible on the web. However, to do this we’ve sacrificed semantic HTML and made our applications inaccessible to a huge amount of different users. Instead of breaking the foundation of the web, we should consider this as an opportunity: how can we implement applications in a way that works for any user who might come along and want to interact with it?

Tests Granularity

In two previous posts we discussed the benefits of automated tests and the properties of a good test. So far we were trying to avoid differentiating the tests in any way. This time we want to address one way how tests can be classified: tests granularity.

Why you should write automated tests

This blog post gives an overview of the most common benefits gained by writing automated tests. It starts in a place where most of the projects we’ve seen so far are: tests are written as a last step of the development process. Then it shows additional benefits that could be gained if we all gave the tests a bit more focus and care.

Cookie-based Spring Security Session

If you need authentication within your Spring Boot web application, the natural choice is to use Spring Security. It’s easy to use and, as long as you stick close to the defaults, it’s also quite easy to configure. But, by sticking to those defaults, you will automatically get a session that is persisted on the server-side. That’s a problem.

Injecting polyfills for missing JavaScript functions into WKWebView

Hybrid apps often use the WKWebView to display the web app part. Unfortunately there is no console output to being able to debug it. This blog post provides a guide on how to add polyfills to WKWebView with native code interaction. As a result you will be able to catch the console output of a webpage loaded in a WKWebView and print it to the Xcode debug console.

Integral Evolutionary Organizations

Most companies face the major challenge to get as many employees as possible actively involved, that they do not only do service as a small cog in the big gear, but that they contribute actively, creatively with their various skills and abilities. In his book Reinventing Organizations [1] Frederic Laloux presents integral evolutionary forms of organization as a solution. This text presents the core ideas supported also by other sources.

Cross-platform testing of TypeScript code with Jasmine and Karma

I like TypeScript. Writing code that already underwent basic checks (i.e. typechecking) before it can even touch an execution engine is a big win in my book. In particular, TypeScript is nice because it integrates well into the broader JavaScript ecosystem and comes with batteries (i.e. types) included. Unfortunately, most test runners require extra setup to work with tests written in TypeScript. Some even require staggering amounts of configuration.

Remote work

Last week we switched INNOQ to 100% remote work. The reason for this radical (or radical-looking) step was the spread of the novel Corona virus SARS-CoV-2, which needs to be contained. In concrete terms, this means that all our consultants will temporarily work exclusively in the home office.

About unit and integration tests

The terms unit test and integration test are typically used as something different, or even opposite. In this blog post I explain why this is misleading and how I prefer to talk about isolation vs. integration instead.
