Udacity's Android Developer Nanodegree Updated To Android Architecture Components

Udacity's Android Developer Nanodegree gets up to speed with Android Architecture Components with an important update. This recognizes that the components are growing in popularity and can  even be considered the modern way of doing things on the platform.
This new class talks us through the four subtopics that comprise the Architecture Components:
1. The Room persistence library - an ORM for easier interaction with a backend database.
2. LiveData - based on RxJava and the Observer pattern so that the UI can be  automatically updated upon any change happening to the underlying data store.
3. ViewModel - Caching and preserving data/state during configuration changes.
4. Lifecycle Aware Components - to make objects that haven't got a lifecycle (as defined by the platform) to become lifecyle aware.

Book Review : How To Create Pragmatic, Lightweight Languages

At last, a guide that makes creating a language with its associated baggage of lexers, parsers and compilers, accessible to mere mortals, rather to a group of a few hardcore eclectics as it stood until now.

The first thing that catches the eye, is the subtitle:

The unix philosophy applied to language design, for GPLs and DSLs"
What is meant by "unix philosophy" ?. It's taking simple, high quality components and combining them together in smart ways to obtain a complex result; the exact approach the book adopts.
I'm getting ahead here, but a first sample of this philosophy becomes apparent at the beginnings of Chapter 5 where the Parser treats and calls the Lexer like  unix's pipes as in lexer|parser. Until the end of the book, this pipeline is going to become larger, like a chain, due to the amount of components that end up interacting together.

The book opens by putting things into perspective in Chapter 1: Motivation: why do you want to build lan…

EU Blockchain Observatory and Forum Blockchain AMA

The EU Blockchain Observatory is a recent initiative, launched in February 2018, which is backed by the European Commission with the primary aim of educating the EU's public on Blockchain technology.This very interesting AMA really served that purpose by answering  the public's challenging questions, which were mainly tweeted under the #AMABlockchain hashtag. Educating the public aside, the forum's two other objectives are to accelerate the application of this technology at a pan-European level and to push for cooperation between member states to materialize uses cases and scenarios backed by Blockchain. The AMA started smoothly tackling lightweight questions, such as "what is the Blockchain technology?" or "where is a Bitcoin stored?", (answer: "on every computer in the Blockchain network"), continuing with what a blockchain Node is and what does a Miner do. Other questions revolved around which Consensus algorithms does a blockchain network…
