Dependency Injection in Functional Programming

There exist several DI frameworks / libraries in the Scala ecosystem. But the more functional code you write the more you'll realize there's no need to use any of them.

A few of the most claimed benefits are the following:

Dependency Injection.
Life cycle management.
Dependency graph rewriting.

58 bytes of CSS to look great nearly everywhere

When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:

main {
  max-width: 38rem;
  padding: 2rem;
  margin: auto;
}

Async/Await - The challenges besides syntax - Cancellation

This is the second article in a series of articles around Rusts new async/await feature. The first article about interfaces can be found here.

In this part of the series we want to a look at a mechanism which behaves very different in Rust than in all other languages which feature async/await support. This mechanism is Cancellation.

	1 - Create a private GitHub/Bitbucket or similar git repo. Here I assume the repo is:

	https://github.com/calkan/bash_history.git

	2 - Create .history directory and initialize it for the repo:

	mkdir $HOME/.history
	cd $HOME/.history
	git init
	touch README.md

	/**
	A markov-chain based glyph generator. Given sequences of points as a corpus, this will create a markov chain based on those points.

	Then, by sampling the chain, we can generate entirely new glyphs that weren't in our original dataset.

	Press "r" to generate a new frame. Press "s" to save the frame to a file (with a random UUID as its name).

	Requires the PostFx library: https://github.com/cansik/processing-postfx/
