How to Boot-strap and Create .NET Projects
To create a .NET project from scratch, simply using Visual Studio Wizard is good enough most of the time. However, the default project settings produced by wizards are hardly acceptable for professional teams, as they set too low of a bar on quality.
In this article, Toptal Freelance Software Engineer Andrei Smirnov guides us through several standard practices, configuration files, and project settings every developer should apply when starting a new .NET project. Doing this in the very beginning of a project decreases future technical debt and makes product source code readable and professional-looking.

Introduction To PHP 7: What's New And What's Gone
If you haven’t been working with PHP lately, you might wonder what happened to PHP 6. Why the skip from PHP 5 to PHP 7? Well, long story short, PHP 6 was a failure. To avoid confusion, the new version was renamed PHP 7.
