My name is Arend-Paul Spijkerman (but i'm also known to listen to 'Paul' or even 'A.P.').
I was born in city of Purmerend in the Netherlands in 1968, later lived in Zaandam until my family moved
to the countryside in the north-east of the Netherlands when i was aged 10.
i learned electrical engineering (at C-level with German) ('80-'84) at the LTS in Musselkanaal.
i studied electronics (with telecommunication) ('84-'88) at the MTS in Stadskanaal.
and technical computer science (= computer science plus electronics) ('88-'92) at the HTS in Emmen.
Services I can provide.
-Software development for Mac, Windows, Amiga, Android and Linux.
-Programming of internet programs, video programs, GUI and graphics programs.
-Programming of 8 & 32 bit microcontrollers and processors, Scenix SX, PIC, 6502, Z80, ARM, XMOS.
-Programming of MBED, lpcxpresso, javelin stamp, basic stamp devices.
-Digital and Analogue circuit designs.
-Prototyping of small devices.
To make software developing easier, i have written a C library that provides a
lot of functionality and compiles on MS Windows x86 and MS Windows .NET, it compiles
on apple Mac using Codewarrior or XCode, it compiles on Linux using GCC and
it compiles on old and new Amigas using SAS-C or GCC.
Which means, i can develop a program on one machine .. say a Mac with codewarrior,
and then copy the source code to the other platforms and compile working executables
without the need of making changes.
The library contains basic functionality but also more complex functionality.
Like functions to allocate memory (with build in code to check if all memory was
deAllocated without being overwritten) and functions to handle doubly linked lists.
There are file access functions, including more complex functions to load line formated
files or XML files.
There is a library of "save" functions to handle text strings.
Also it contains functions for internet access, and client/server logic.
It contains functions to load and save pictures, and to do all sort of functions
to perform actions on pictures, like scaling, texturing etc.
There is even an engine for 2D/3D games.
Some of the more complex functions are the Dynamic GUI engine, this part handles
all of the setting up, displaying and handling of GUIs. Where the GUI can contain
background pictures, and all kind of effects.
The GUI can even be defined in a text file, so it can easily be changed later.
So to handle the GUI the main program only needs a handfull of calls.
The GUI code has enough functionality so it can be used in my webbrowser.
Also on Mac and windows there is a video play object, so videos can be shown in the GUI.
There is an audio player for Mac, Windows, Android etc which supports MP3 and avi tags.

A BBS system is a computer useally at someone's home (in the age before the internet)
that people call with their computer and a modem to chat, exchange mail or download or play games.
The system is Multinode and has a internal server program for resources like messages, files etc.
for the nodes and mail and file processors to use.
It has a front end calling/answering software for automated login, or transfer to other software
like fax software .. and has an automated file exchange mode. So it can call other systems at night
and exchange mail and files.
It has mail and file processors to route those through the network of computers.
It has a RIPscrip interpreter for screens with RIP graphics.
