Application Development

Introducing PyInstaller

Want to distribute Python programs to your Python-less clients? PyInstaller is the answer. If you're used to working with a compiled language, the notion that you would need to have a programming language around, not just for development but also for running an application, seems a bit weird. Just because a program was written in C doesn't mean you need a C compiler in order to run it, right?

Developing Console Applications with Bash

As a novice software developer, the one thing I look for when choosing a programming language is this: is there a library that allows me to interface with the system to accomplish a task? If Python didn't have Flask, I might choose a different language to write a web application. For this same reason, I've begun to develop many, admittedly small, applications with Bash. Although Python, for example, has many modules to import and extend functionality, Bash has thousands of commands that perform a variety of features, including string manipulation, mathematic computation, encryption and database operations. In this article, I take a look at these features and how to use them easily within a Bash application.

Creating an Application-Based Terminal Session

One of my first exposures to computers in a work environment was using a Wyse terminal to access a console-based application for data entry. It wasn't until a while later that I learned about terminals in UNIX and how they work. Once I understood it, I wanted to create my own self-contained application that was tied to a telnet or SSH session.

LinkedIn's {py}gradle

To facilitate better building of Android apps, the technical team at LinkedIn has developed {py}gradle, a new powerful, flexible and reusable Python packaging system. Now available to the Open Source community, {py}gradle wraps Python code into the Gradle build automation tool so that developers can build Android apps more easily.

Synopsys' Coverity

The new version 8.5 of Synopsys' Coverity extends the security umbrella of the static analysis tool to mitigate a wider range of security vulnerabilities.

Client-Side Performance

In past articles, I've covered different ways to understand, analyze and improve the performance of your web applications. I've shown that between your network connections, server hardware, database design and HTTP server configuration, you can change and improve the performance of your web application—well, sort of.

The Qt Company's Qt Start-Up

The Qt Company is proud to offer a new version of the Qt for Application Development package called Qt Start-Up, the company's C++-based framework of libraries and tools that enables t

Multitenant Sites

For some time now, there has been tremendous growth in the world of Web applications. It's quite amazing to see what you can do just via a Web browser—not only can you buy just about anything, but also a growing number of sites offer "software as a service", often abbreviated as SaaS. The idea is that in exchange for a monthly service fee, you get access to a service.

Promise Theory—What Is It?

During the past 20 years, there has been a growing sense of inadequacy about the "command and control" model for managing IT systems. Years in front of the television with a remote control have left us hard pressed to think of any other way of making machines work for us.


Back when I started to use the Internet in 1988, there was a simple way to get answers to your technical questions. You would go onto "Netnews", also known as Usenet, and you would post your question to one of the forums. There were forums, or "newsgroups", on nearly every possible topic, from programming languages to religions to humor.


There's an old saying in the real-estate business that the three most important things in a property are location, location and location. We can assume this is still true when it comes to real estate, but it also is increasingly true when it comes to Web applications.

A Shining Ruby in Production Environments

Even the most beautiful Rails application can lose its elegance if not deployed correctly. Like other Ruby frameworks or languages, such as Sinatra, Rails is based on the Rack interface. This article provides a basic introduction to Rack hosting and Rack-based application deployments.

Cloud Computing Basics—Platform as a Service (PaaS)

Generally, good programming is considered to be the measured application of an art form, craft or discipline, with the objective of producing a competent and evolving business solution. In traditional environments, computer programming is a practice that has multiple phases, such as designing, developing, testing, debugging and maintaining application code.

AIDE—Developing for Android on Android

Android, as a platform, is one of the fastest growing on the planet. It is available on smartphones and a series of different tablet sizes. Most devices also include a full spectrum of sensors that are available to programs you install, so it's a very inviting platform for development.
