AWS Lambda offers a relatively thin service with a rich set of ancillary configuration options, making it possible to implement easily scalable and maintainable applications leveraging these services.

In this article, Toptal engineer Andrew Crosio gives us a step-by-step tutorial for building an image uploading and resizing service and demonstrates how AWS Lambda can be used as a platform to easily build service-oriented architecture applications.

Python is a powerful, object-based, high-level programming language with dynamic typing and binding. Due to its flexibility and power, developers often employ certain rules, or Python design patterns. What makes them so important and what do does this mean for the average Python developer?

In this post, Toptal Senior Software Engineer Andrei Boyanov explains why Python is great for design patterns, and how they can be used to unlock even more potential, or to streamline development and make code more maintainable.

Nowadays, almost all Python frameworks use WSGI as a means, if not the only means, to communicate with their web servers. This is how Django, Flask, and many other popular frameworks do it.

This article intends to provide readers with a glimpse into how WSGI works and allow them to build a simple WSGI application or server.

Analysts have come to recognize social network data as a virtual treasure trove of information for sensing public opinion trends and groundswells of support. In this article, Toptal Engineer Elder Santos describes the techniques he employed for a proof-of-concept that effectively analyzed Twitter Trend Topics to predict, as a sample test case, regional voting patterns in the 2014 Brazilian presidential election.

Although the most wide-spread and supported way of running Django is on a Linux system (e.g., with uwsgi and nginx), it actually doesn’t take much work to get it to run on IIS. In this article, Toptal Engineer Ivan Voras walks you through a step-by-step tutorial, clearly explaining how to install Django on IIS.

Reverse engineering and hacking are usually related to malicious activities that result in sleepless nights of engineers responsible for system maintenance.

Reverse engineering is a tool that we can utilize to find the flaws and improve our software in many aspects. This article shows us how to use these techniques to learn more about different implementations of web API.

Scientific computing is hard. But thanks to an ever-growing landscape of open source tools, really tough problems are becoming easier to solve. Toptal engineer Charles Cook provides an in-depth example, leveraging open source tools to solve a problem in computational fluid dynamics.

Python’s simple, easy-to-learn syntax can mislead Python developers – especially those who are newer to the language – into missing some of its subtleties and underestimating the power of the language.

In this article, Toptal’s Martin Chikilian presents a “top 10” list of somewhat subtle, harder-to-catch mistakes that can trip up even the most advanced Python developer.

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.
