Merge Wiki Changes From A Forked Github Repo

This is inspired (or basically copied) from How To Merge Github Wiki Changes From One Repository To Another, by Roman Ivanov, and serves to ensure that should something happen to the original article, the information remains nice and safe here.

Terminology

OREPO: original repo - the repo created or maintained by the owner

FREPO: the forked repo that presumably has updates to its wiki, not yet on the OREPO

Using Selenium and Python to screenshot a javascript-heavy page

As websites become more JavaScript heavy, it's harder to automate things like screenshotting for archival purposes. I've seen examples and suggestions to use PhantomJS for visual testing/archiving of websites, but have run into issues such as the non-rendering of webfonts. I've never tried out Selenium until today...and while I'm not thinking about performance implications yet, Selenium seems far more accurate than PhantomJS...which makes sense since it actually opens a real browser. And it's not too hard to script to do complex interactions: here's an [example of how to log in to Twitter, write a tweet, upload an image, and send a tweet via Selenium and DOM element selection](https://gist.github.com/dannguyen/8a6fa49253c1d6a0eb92

	import scala.util.{Success, Failure}

	val f: Future[List[String]] = Future {
	session.getRecentPosts
	}

	f onComplete {
	case Success(posts) => for (post <- posts) println(post)
	case Failure(t) => println("An error has occured: " + t.getMessage)
	}

	EntityManager em = emf.createEntityManager();
	em.getTransaction().begin();

	EntityGraph<?> graph = em.getEntityGraph("graph.AuthorBooks");
	HashMap<String, Object> properties = new HashMap<>();
	properties.put("javax.persistence.fetchgraph", graph);

	Author a = em.find(Author.class, 1L, properties);

	em.getTransaction().commit();

	; Основан на том, что имея некоторое неточное значение y
