Insider's Guide To Udacity Android Developer Nanodegree Part 5 - Make Your App Material

Having embarked on this account of the Android Developer Nanodegree, designed by Google and delivered through Udacity's platform, in March, we've already covered a lot of skills. This part  tackles mission impossible, turning a Coder into a Designer.

I always aim for functionality first and design second, something clearly evident in my Nanodegree projects submitted thus far which satisfied just the UI essentials but also in my other unrelated-to Android-work, such as Ultimate Extract and Recover, a Win32 application and Smart Device Seeker, a Website about smart devices. So "design second" doesn't pertain just to Android applications but crosses boundaries and I guess that's something prevalent to most backend-oriented developers out there.

This has to change since design plays a big role in what breaks or makes success and, with so much competition in the Android store, producing just a functional application is not enough. This makes sense since the user's first encounter is with the 'get to know' phase that depends on the aesthetic, layout, setup and organization part of the application, taking place much earlier than the functionality assessment phase.

Thankfully, as there's patterns for everything, so there are for designing UIs and on the Android platform they're collectively known as 'Material Design'.

In addition to standardizing aesthetics with color palettes, typography, imagery and so on, Material Design also sets up a common ground for all Android apps to be built upon so that end users are able to transfer their experience of using one app to the using of another. That's why the 'Hamburger' icon, the rounded Contacts of Gmail, the flipping of pages by swiping left and right are patterns so frequently met across all Android applications.

Then again, while 'Material Design' might be the recommended way, it does not enforce strict or uncrossable boundaries, as any app is free to deviate when necessary, typically when wanting to infuse the brand's signature and that feeling of uniqueness.
The class is organized in 5 distinct units including the end project:

How Much Gameplay Can You Pack In Just 13K?

Given our expectations of Xbox games, you might consider writing a game within a 13K limit, which is the challenge for the annual js13K competition far too restrictive. Its results are now out and prove that it is possible to produce a game that is fun to play. 

Back in the tape loading days and on platforms the likes of Commodore64 games came in sizes of 4K or less. As proof of concept, here's a list of a few such 4K titles, copied over from Lemon64 's archive:
Alien SidestepBug CrusherDot GobblerClose EncountersDot Gobbler v2GridrunnerLaser CyclesMarios BrewerySpace ActionSpace RicoshayTank WarsHesmon64Retro Ball  Fast forward to now, at a time when Javascript's eating the world by making all sorts of applications or  games available to everyone through the medium of the browser, rendering the need of dedicated platforms and Operating systems obsolete, 13K is sufficient enough to pack both gameplay AND cool graphics due to the advanced browser engines and HTML5.

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…

Hour of Code 2017 Introduces App Lab

t's the time of year when the world-class Hour of Code once more commences; just an hour for introducing coding to the uninitiated, having them complete self guided tutorials. But is a hour sufficient? What can a beginner actually code within this limit? The answer is a bit more complicated than that, so let's find out all about it! Integrated into the larger, worldwide, annual Computer Science Education week, this year taking place December 4-10, Hour of Code's novel mission has always been to get everybody coding, aged from 4 to 104, by providing: "a one-hour introduction to computer science, designed to demystify code, showing that anybody can learn the basics, and broadening participation in the field of computer science". But first of all, why this obsession with Computer Science, in particular in getting  kids as young as 4 to learn to code? The answer is simple. Nowadays code is everywhere around us, from desktop computers to mobile phones and, thanks to w…
