Emoji, Emoji, What for Art Thou? Lisa Lebduska By providing a history and context for emojis, this essay argues that they are more a means of creative graphic expression than a threat to alphabetic literacy, and that their study contributes to a re-materilaizing of literacy.
Introduction Today I thought I'd talk about a neat design pattern that doesn't seem to get much love: In its fullest form it's also sometimes called the Prototype Pattern.
People use this pattern all over the place, and I'll give you a nice set of real-life examples in a little bit. It's a design pattern that's useful in every programming language, and as we'll see shortly, it's also pretty darn useful as a general-purpose persistence strategy.
But even though this pattern is near-universal, people don't talk about it very often. I think this is because while it's remarkably flexible and adaptable, the Properties Pattern has a reputation for not being "real" design or "real" modeling.
In fact it's often viewed as a something of a shameful cheat, particularly by overly-zealous proponents of object-oriented design in language domains or relational design in database domains. I hope to offer a different and richer perspective here.
With luck, this article might even help begin the process making the Properties Pattern somewhat fashionable again.
Three Great Schools of Software Modeling Before I tell you anything else about the Properties Pattern, let's review some of the most popular techniques we programmers have for modeling problems.
I should point out that none of these techniques is tied to "static typing" or "dynamic typing" per se. Each of these modeling techniques can be used with or without static checking. The modeling problem is orthogonal to static typing, so regardless of your feelings about static checking, you should recognize the intrinsic value in each of these techniques.
Class Modeling You know all about this one. Class-based OO design is the pound gorilla of domain modeling these days. Its appeal is that it's a natural match for the way we already model things in everyday life. It can take a little practice at first, but for most people class modeling quickly becomes second nature.
Although the industry loves OO design, it's not especially well liked as an academic topic.
This is because OO design has no real mathematical foundation to support it — at least, not until someone comes along and creates a formal model for side effects. The concepts of OOP stem not from mathematics but from fuzzy intuition.
This in some sense explains its popularity, and it also explains why OOP has so many subtly different flavors in practice: Industry folks can never quite agree on what OOP is, but we love it all the same. Relational Modeling Relational database modeling is a bit harder and takes more practice, because its strength stems from its mathematical foundation.
Relational modeling can be intuitive, depending on the problem domain, but most people would agree that it is not necessarily so: Object modeling and relational modeling produce very different designs, each with its strengths and weaknesses, and one of the trickiest problems we face in our industry has always been the object-relational mapping ORM problem.
It's a big deal.Developed for AS Media Studies - WJEC MS1 spec. Designed to help students complete representation essays - giving them hints and structure for the essay. • Recognise and analyse representations evident in the stimulus material. • Demons. Of the silent trilogy, Earth () is Dovzhenko’s most accessible film but, perhaps for these same reasons, most misunderstood.
In a Brussels’ film jury would vote Earth as one of the great films of all time. Earth marks a threshold in Dovzhenko’s career emblematic of a turning point in the Ukrainian cultural and political avant-garde - the end of one period and transition to another.
In fact, essays are utterly simple to write since they normally include the author’s view. For those who’ve ever employed article composing solutions, you may be below the perception it charges a good deal. Representationalism definition is - the doctrine that the immediate object of knowledge is an idea in the mind distinct from the external object which is the occasion of perception.
How to use representationalism in a sentence. the theory or practice of realistic representation in art. John Locke (b. , d. ) was a British philosopher, Oxford academic and medical researcher.
Locke’s monumental An Essay Concerning Human Understanding () is one of the first great defenses of modern empiricism and concerns itself with determining the limits of human understanding in respect to a wide spectrum of topics. It thus tells us in some detail what one can legitimately claim. Disclaimer: This essay has been submitted by a student.
