Building Apps in Swift: Using Storyboards

1
In our previous article on building apps with Apple’s Swift, we demonstrated how to use view controllers and views in code to craft a simple app. Before we begin with this next lesson, using storyboards to build an app in Swift, it’s worth revisiting that first piece. (The code that accompanies the piece is stored on SourceForge as “First Example.zip.”) Remember that view controllers in Swift manage two roles: they controls views on a page or part of a page,… continue…

A Look at 5 Free Python Editors

PyScripter
Python programming can be done from the command line, but an IDE makes life so much easier. With so many options out there, which one should you use? To help you decide, I’ve looked at five Python editors (all free). Although Python has been more of a Linux programming language, the last few years have seen its increasing use on Windows, so many of the five are cross-platform. They are: Eclipse plus PyDev and other plugins PyScripter Eric Python IDE… continue…

How to Build Apps in Swift

Earlier this year, Apple executives unveiled Swift, which is meant to eventually replace Objective-C as the programming language of choice for Macs and iOS devices. While Objective-C remains popular, developers frequently complain about how difficult it is to use; Swift’s features will supposedly eliminate at least some of those issues. Despite its ease of use, developers will still need to spend some time learning how the language works. This is the first of a few articles that show how to… continue…

Unpopular Programming Languages That Are Still Lucrative

In a previous article, I discussed the best programming languages to learn over the next year. Most of those were popular languages such as C#, JavaScript, PHP, and Swift. (I also did a follow-up that sang the virtues of Objective-C and Python.) But that’s not the final story on languages: Programmers can also benefit from learning other, less popular languages that could end up paying off big—provided the programmers who pursue them play their proverbial cards right. And as with… continue…

Passing Functions as Parameters

Passing a Function as Parameter in C#
When I first started programming in the late 1970s, I was heavily into Pascal and the concept of passing an address as a parameter was just unheard of outside of academic circles. Procedural programming treated functions as something that were called, not passed around. Had I known C then—which had been around since the early 1970s—I might have been more aware of function pointers. If you don’t know C that well, a pointer is a variable that holds the memory… continue…

Why Don’t Software Engineers Get More Respect?

Tearing Up Resume
Not many people would argue that technology isn’t central to business nowadays. It’s hard to imagine any kind of company of any size operating without some kind of technical system in place to support it—if not drive it. So why don’t software engineers get more respect? That’s what TechCrunch columnist Jon Evans was thinking about the other day. What got him going was a blog post by Michael O. Church, a software engineer who blogged about how differently he was… continue…

Creating Random Access Text in C#

Contents of the Two Files
Back in April I looked at disk folders as a possible alternative to NoSQL or using a relational DB. My conclusion wasn’t encouraging—I was concerned about poor performance, especially on Linux. The use case I examined was for a server that had from 100,000 to 1 million users. I wanted to store and retrieve text files for any user. Those files could vary in length from a few bytes to a few KB. Back in the dark ages—before the Web… continue…

Are Python and Objective-C Worth Learning?

Last week’s article on the five programming languages you’ll need next year (and beyond) didn’t include two important languages: Python and Objective-C. Python’s exclusion sparked a passionate response from some readers, to say the least, and led us to craft a follow-up to emphasize Python’s importance to the programming world. Python is mature (the first version, created by a computer scientist named Guido van Rossum, was released in 1991). Google, where van Rossum worked for several years, has embraced Python… continue…

6 Developer Tips for Better Disaster Recovery

Blue Screen of Death
You go through life thinking that it won’t happen to you, but someday it will: Your development PC suddenly goes from being state-of-the-art to having the computing power of a brick. How quickly you get back into action depends upon your budget and preparedness. Over the recent July 4 weekend it happened to me. The disaster was partially of my own making. Thanks to a slightly dodgy set of RAM—both Ubuntu and Windows 7 memory tests agreed on this—I was… continue…

Python, Swift, JavaScript, Java: Best Ways to Learn Them

Learning a new programming language—or merely staying adept in ones you know already—is a necessary challenge for programmers and developers who want to stay relevant. Fortunately, every popular programming language comes with tons of documentation, as well as a variety of online tutorials. Check out these handy resources: JavaScript ranks high on everybody’s list of the most popular programming languages. Earlier this summer, for example, tech-industry analyst firm RedMonk drew publicly available data from GitHub and Stack Overflow that suggested… continue…
