This post explores some of the more common types of GPS tracking errors to expect with low-end GPS devices, providing an understanding of what causes them as well as some approaches for correcting them. The techniques outlined can provide users of low-end GPS devices with a reasonable level of automated improvement of the accuracy of their GPS tracks.
I often hear iOS developers ask some variant of the same key question: "What's the best way to develop a UI in iOS: through Storyboards, NIBs, or code?" Answers to this question, explicitly or implicitly, tend to assume that there's a mutually exclusive choice to be made, one that is often addressed upfront, before development. I'm of the opinion that there's no single choice to be made. Rather, each option has its strengths and weaknesses—and there's no need to use any one of them in isolation.

Go is a relatively new language with a number of attractive features. It's great for writing concurrent programs, thanks to an excellent set of low-level features for handling concurrency. In many cases, though, a handful of reusable abstractions over those low-level mechanisms makes life much easier. This introductory tutorial walks you through building one such abstraction: a wrapper that can turn any data structure into a transactional service in Go.
The recent resurgence in Artificial Intelligence has been powered in no small part by a new trend in machine learning, known as "Deep Learning". In this article, I'll introduce you to the key concepts and algorithms behind Deep Learning, beginning with the simplest building block.
Beyond its beauty, in recent years Córdoba has been enjoying a rapidly growing reputation as a technology center, one that may soon rival Buenos Aires as Argentina’s main technology hub. Last month, Toptal coordinated and hosted a highly successful and well-attended JavaScript Technical Conference in Córdoba, Argentina. Read about how the event came together and the vibrant network of software developers in and around Córdoba.
I love and use Django in lots of my personal and client projects, mostly for those involving relational databases and more classical web applications. However, by design, Django is very tightly coupled with its ORM, Template Engine System, and Settings object. Plus, it's not a new project: it carries a lot of baggage from the past to remain backwards compatible. In a few of my client projects, we've chosen to give up on Django and use a micro framework like Flask, typically when the client wants to do some interesting stuff with the framework. At the same time, we often need user registration, login, and more, all of which is easily handled with Django. The question emerged: is Django an all-or-nothing deal? Should we drop it completely from the project, or is there a way to combine some it with the flexibility of other frameworks?
Writing concurrent programs is hard. Having to deal with threads, locks, race conditions, and so on is highly error-prone and can lead to code that is difficult to read, test, and maintain. This post provides an introductory guide to the Scala-based Akka framework, showing (with code samples) how Akka facilitates and simplifies the implementation of robust, concurrent, fault-tolerant applications.
With an 80% increase in the remote workforce from 2005 to 2012, there must be more to the picture than meets the eye. This post pulls the rug out from under 5 of the most prevalent myths about remote workers, with a specific focus on the software development industry.
