+# About me
+
+<img src="/media/me_header.jpg" alt="picture of me in Scotland" class="full clear"/>
+
+Hi, my name is Adrian Kummerländer. I am a Software Developer located in southern Germany.
+
+I taught myself programming at the age of 10 and spent the first few years developing software in _Delphi_ and _C#_. After my switch to _Linux_ as my primary operating system I started developing primarily in _JavaScript_, _XSLT_ and _C++_ altough I very much enjoy trying out other languages such as _Scala_ and _Python_.
+
+My professional education in software development started with my apprenticeship as a _"computer science expert with subject area software development"_[^1] at [_Sybit_](http://sybit.de) in 2010 which I concluded with distinction in 2013. 
+
+While my primary activity nowadays is studiying for my A levels at the _Technische Oberschule_ I still work as a part-time developer at _Sybit_ in the _SAP CRM_ area where I mainly develop business printout processes using _ABAP_, _JavaScript_ and _XSLT_ in addition to _SAP WebUI_ development.
+
+Although software development and tickering with my computer systems definitely is a primary occupation of mine both professionally and recreationally, I also enjoy reading _hard science fiction_ books and attending concerts and festivals of _orchestral_ and _Metal_ music. If you are interested, a overview of my musical interests is available as a [blog article](/article/musikalischer_jahresruekblick_2013/) in German. 
+
+I use this website to document some of my [thoughts and experiences](/archive) concerning software development and various other topics in addition to summarizing some of my [projects](/category/projects).
+
+[^1]: This really is the official translation of my recognized trade but I for one prefer referring to myself simply as Software Developer

+# BinaryMapping
+
+…is a collection of C++ templates which may be used to map binary structures into tuples and various other structures.
+
+These structures can then be traversed using integrated containers and iterators. This is useful for many kinds of data serialization tasks.
+
+A explanation of an earlier version of this template library can be found on this [blog]. The source code is available via both [Github] and [cgit].
+
+## Current features
+
+* Support for any kind of flat structure that can be expressed using integral types and arbitrarily sized byte-arrays
+* Support for serialization in either big or little endianess
+* Offers Container and Iterator templates for fast traversal of collections of tuples or other structures
+* Support for developing custom types to be used in the Container and Iterator templates
+* Support for nesting structures inside each other
+* BitField template offers bit-level access to ByteField byte-arrays
+* Doesn't require any external libraries besides the GNU libraries `endian.h`
+* Header only library because of heavy usage of template metaprogramming
+* Unit Tests based on GoogleTest
+* MIT license

+# CodepointIterator
+
+…is a `std::iterator` derived class implementing the `std::bidirectional_iterator_tag` which iterates through unicode codepoints in a UTF8-encoded string.
+
+The source code is available on both my [Github] profile and [cgit].
+
+## Current features
+
+* Bidirectional iteration through unicode codepoints
+* The class itself does not rely on any external libraries
+* Dereferencing an instance of the iterator yields the codepoint as `char32_t`
+* Unit Tests based on GoogleTest

+# GraphStorage
+
+…is a Graph storage and query library based on LevelDB.
+
+It currently supports integer indexed nodes with properties and directed edges with types. The integer IDs are serialized _by hand_, values are serialized using protocol buffers. Everything is stored in a single sorted LevelDB database.
+
+Queries are possible trough a iterator like interface that handles single level queries quite fast. Additionally changes to edges can be monitored using a subscription mechanism.
+
+The library is in development and while not intended for any kind of production usage the source code is available via both [Github] and [cgit].

+# InputXSLT
+
+…is a Apache Xalan based XSLT extension enabling access to external commands, the filesystem and calling further transformations from inside a transformation.
+
+It is used as the base for the static site generation system used to generate the whole website you are currently viewing and is available via [Github] or [cgit].
+
+## Why?
+
+Contrary to popular opinion I actually like XSLT as a content transformation language and have built - amongst other things - most of my website projects on top of it. While I used the XSLT based [Symphony CMS] for most of these endeavours, the intention behind InputXSLT was to develop XSLT extensions enabling the development of static site generators using XSLT as both a template and application language. The fact that you are currently reading this page proves that this is indeed possible.
+
+## Overview
+
+The following table summarizes all the external functions provided by InputXSLT. They are available under the `InputXSLT` namespace after including `function.inputxslt.application` into the stylesheet element. 
+
+|Function           |Description                                                                                                   |
+|`read-file`        |Reading plain text files as text and XML files as node trees                                                  |
+|`read-directory`   |Traversing filesystem directories                                                                             |
+|`external-command` |Executing external commands including support for providing the input stream and capturing the output stream  |
+|`write-file`       |Committing plain text or node trees to the filesystem                                                         |
+|`generate`         |Calling transformations including support for capturing the result or committing it directly to the filesystem|
+
+The `ixslt` XSLT frontent provided by InputXSLT also implements a custom include entity resolver alongside to an easy to use interface for implementing further custom extension functions.
+
+## Tradeoffs and compromises
+
+All external functions offered by InputXSLT can be accessed using the XPath expression evaluation subsystems of the XSLT language. While in some cases XSL extension elements would have been the primary choice limitations in the C++ implementation of the Apache Xalan XSLT library made the usage of external functions the path of least resistance. In practice external functions like the one used to call other transformations are wrapped inside utility templates and as such may be used as if they where implemented as extension elements. All other functions like the ones used to access the filesystem fit better within a XPath-expression context and are as such implemented in the most fitting way.

+# SimpleParser
+
+…is a simple parser for resolving mathematical terms.
+
+The term is parsed by generating a binary expression tree using the Shunting-Yard algorithm. The implementation itself does not use any external libraries and relies fully on the features provided by the C++ language and the standard library.
+
+This application marks the first steps in C++ I took a couple of years back and is available on [Github] or [cgit].
+
+## Current features
