I recently destroyed my good old Nexus 6 phone. It’s still working, but display screen is broken. Due to this fact, I’ve had an excuse to buy new Pixel 2 phone. It’s pretty expansive, but its quality is really good. As usual, I wanted to debug an app on this device and encountered problem related to device permissions. Once I connected the phone, to my laptop and typed adb devices, I’ve seen the following message:...
Introduction I have my own tiny Python project called spotify-cli-linux, which is (surprise!) command line interface for Spotify desktop app on Linux. Python is not my primary programming language and I work more with Java. Nevertheless, I find this language enjoyable and useful in many cases, so I try to learn something new about it from time to time.

Introduction In the cloud computing era, companies start using services like Google Cloud Platform, Amazon Web Services or Microsoft Azure. We can hear about the term “Serverless”. It doesn’t mean that we don’t have any servers.

We have concepts like Backend as a Service (BaaS) and Funtion as a Service (FaaS)....
Today, I’ve released my another tiny project. It’s a very simple implementation of Event Bus with RxJava 2 under the hood. This library is compatible with Java 1.7 or higher. I didn’t use Java 1.8 or 1.9 because I wanted to make it compatible with Android apps. You can use it as follows: Bus bus = ReactiveBus.create(); Disposable observer = bus.receive().subscribe(new Consumer<Event>() { @Override public void accept(Event event) { // handle event here } }); Once, we created Event Bus object and our observer (or more precisely: disposable subscriber), we can start sending events:...
