Code Clinic: 6 Problems in 6 Programming Languages

CodeClinic

“Learn to code!” It’s the latest buzzphrase. Everyone from Barack Obama to Will.i.am is talking up the importance of learning a programming language—which is good. But it’s only part of the story.

Successful programmers know more than just a computer language. They also know how to think about solving problems. They use “computational thinking”: breaking a problem down into segments that lend themselves to computer solutions.

Our Developer content at lynda.com already provides a wealth of programming courses geared towards all levels of experience. Starting this month, we’ll also delve into computational thinking—with a unique new set of courses called Code Clinic.

Getting Started with Excel VBA

excel-cells-in-repose

Excel is a powerful and versatile tool you can use to analyze data—but not every capability you might want is built in.

Using the Visual Basic for Applications (VBA) language, you can script custom processes in Excel. VBA is an object-oriented language, which means that elements of Excel—such as workbooks, worksheets, and the program itself—are represented as objects. An object has three main components:

  • properties, which describe the object
  • methods, which are things the object can do
  • events, which are occurrences the object can recognize and react to

Anyone who’s been paying attention to the game development scene can tell you that Unity has evolved very quickly, and has matured into an amazing development environment; and 4.5, the latest release, is no exception. Unity 4.5 focuses a lot on bug fixes (over 450 of them), but there are also some great new features as well. I wanted to take a minute to highlight four of these new features, and talk about how they’ll impact your projects.

Swift: A New Programming Language

Apple's Swift: A New Programming Language

Swift is a new programming language developed by Apple for iOS and OS X app development, which builds on the best parts of many popular languages like Objective-C, Ruby, Python, C# and more. Announced at Apple’s annual WWDC developer conference this year, Swift is the culmination of years of “skunkworks” development alongside optimizations made to Apple’s SDKs and developer tools.

WWDC 2014 Report: What’s New for Apple?

apple-wwdc-2014

Apple’s yearly Worldwide Developer Conference (WWDC) has long been a place where Apple makes major announcements of both hardware and software.

But the keynote at this year’s event, which began this morning in San Francisco, included no new hardware announcements: no new iPhone, no iPad, and no sign of any long-rumored iWatch or Apple TV.

Living with Google Glass

Doug Winnie - Living with Google Glass

Living in San Francisco, you see people wearing Google Glass often: at coffee shops, at restaurants, on trains. The Glass Explorer program, a group of people invited by Google to purchase Glass before its official release, has been expanding over time. As a result, thousands of Explorers are now using Google Glass and informing Google on how to improve it.

I’m part of the program myself, having received my Glass invitation in December. So I plunked down my $1,500 and went to the Google Glass office in San Francisco to pick it up. The “fitting,” as they called it, took place in a cavernous and sparse office building near the Embarcadero with sweeping views of the San Francisco Bay Bridge. A Glass-wearing representative helped me through the setup process then showed me how to connect it to my phone. Afterwards, I was turned loose to wander the streets of San Francisco with my new piece of fancy eyewear.

But instead—I put it away.
