Programming/markup languages

Projects grouped by language they are created in. Majority of the projects utilize many languages at the same time.

ActionScript

I've used it only for coding complex animations in Flash.

C

One of the first programming languages that I came in contact with.

C#

Powerful and flexible, also the primary .NET language for me.

C++

Multi-paradigm and one of the most popular programming languages in the world.

CSS

The Cascading Style Sheets are used in presentation layer in web development.

HTML

By far, the most popular language used to display web pages is HyperText Markup Language.

HTML5

Most recent revision of the HTML standard.

Java

Java programming language may also mean Java SE API.

Java Micro Edition

Mobile edition of Java. Current mobile devices either do not support Java at all, or support Java Standard Edition, but it was not the case in the past.

Since great majority of early and even some recent mobile phones supported Java Micro Edition applications (those are called MIDlets), this was the one of the most portable technologies ever created. Nowadays it's very hard to find a technology that spans so diverse set of devices, although there are several technologies that aspire to that status.

JavaScript

Client-side scripting language, very useful in web development.

LaTeX

Document markup language that I use for scientific papers, and various software engineering artifacts such as user guides, business analyses, technical documentations. I also use it to generate certain documents automatically.

PHP

"The" script language of the web. Very widely used, it also powers this website.

Python

Gradually typed, dynamic, object-oriented programming language. Praised for ease of use at small and large scale.

XAML

Markup language used for declarative UI programming in Windows Presentation Foundation.

XML

Markup language that due to its extensibility can be found almost anywhere. I use it often in serialization.
