Review of LaTeX and Friends by Marc van Dongen (Dutch)
MAPS 44, 2013, 13-14
04.pdf (496kb)
abstract:
Zeggen dat LaTeX niet gemakkelijk is om aan te leren, is een open deur intrappen. Met een degelijk boek als LaTeX and Friends word je meer dan behoorlijk op weg gezet. Saying that LaTeX is not easy to learn is a truism. With a good book like LaTeX and Friends you will more than adequately be put on the road.

Kegelsneden benaderen / Conic approximation (Dutch)
MAPS 44, 2013, 15-26
05.pdf (137kb)
abstract:
Kegelsneden kunnen systematisch worden benaderd door hoekpunten van een (deel van een) omgeschreven veelhoek. Een algoritme wordt ontwikkeld voor het bepalen van de steunpunten van een iteratieve derdegraads "Bézier" benadering van kegelsneden. Voor de start zijn drie punten nodig. Het algoritme is onafhankelijk van de stand van de kegelsnede. Conic sections can systematically be approximated by vertices of a (part of a) circumscribed polygon. An algorithm is developed for the determination of the support points of a third degree iterative "Bezier" approach of a conic. Initially, three points are needed. The algorithm is independent of the position of the conic section.

Pythagoras Trees in PostScript (English)

keywords:
2.5D, Adobe, ALGOL, art, backtracking, BASIC, CWI, Deubert, EPSF, FIFO, fractal, fractal geometry, IDE, Julia set, Lauwerier, Lévy, LIFO, Lindenmayer, minimal encapsulated PostScript, minimal plain TeX, Pascal triangle, Photoshop, production rule, Pythagoras Tree, PSlib, self-similarity, Sierpiński sieve, sentinel, TeX works, (adaptable) user space, Word
abstract:
Pythagoras Trees are drawn elegantly in PostScript, varied by randomness, colour and the use of curves. Lindenmayer production rules for systematic PS program development are enriched by PS concepts.

Classical Math Fractals in PostScript (English)
MAPS 44, 2013, 49-78
07.pdf (1672kb)
keywords:
Acrobat Pro, Adobe, art, attractor, backtracking, Cantor Dust, C curve, dragon curve, fractal, Game of Life, Hilbert curve, infinity, kronkel (twist), Lauwerier, Lévy, Lindenmayer, Minkowski, Monte Carlo, production rule, PSlib, Sierpiński, Star fractals, TACP, Turtle Graphics, von Koch (island)
abstract:
Classical mathematical fractals in BASIC are explained and converted into mean-and-lean EPSF defs, of which the .eps pictures are delivered in .pdf format and cropped to the prescribed BoundingBox when processed by Acrobat Pro, to be included easily in pdf(La)TeX, Word, ... documents. The EPSF fractals are transcriptions of the Turtle Graphics BASIC codes or programmed anew, recursively, based on the production rules of oriented objects. The Lindenmayer production rules are enriched by PostScript concepts. Experience gained in converting a TeX script into WYSIWYG Word is communicated.

Exam Papers Revisited (English)
MAPS 44, 2013, 79-90
08.pdf (125kb)
keywords:
exam, examination, collection, problem, question, multiple choice, ConTeXt, XML, HTML
abstract:
Described is a module for the consistent production and maintenance of student examinations. It can typeset questions with long or short answers, yes/no questions and multiple choice. The questions are formulated as XML documents and access ConTeXt through a special interface with HTML-like syntax.

A bit of HTML and a bit of ConTeXt (English)
MAPS 44, 2013, 91-96
09.pdf (83kb)
keywords:
ConTeXt, HTML, XML, include, vocabulary
abstract:
Described is a module for the typesetting of a subset of HTML operators. These can be used to build data sets in XML with HTML as formatting elements and have them typeset in ConTeXt. Other features are the inclusion of predefined content and provision for language localized words and expressions.

keywords:
ConTeXt, table
abstract:
Described is a module for the typesetting of tables. The module resembles the LaTeX tabular environment but is in fact based on a much older package, the origins of which are lost to the author.

Making the ConTeXt wiki easier to improve (English)
MAPS 44, 2013, 106-108
11.pdf (102kb)
keywords:
documentation, projects, wiki, infrastructure, ConTeXt
abstract:
An effort is underway to encourage both reading and editing of the ConTeXt wiki. This article names nine concrete improvements that are part of this effort, and makes a case for each of them. These nine items are the following. To impose structure and to ease navigation: predictable article names; navboxes; and a simple Main Page. To coordinate efforts: a `How this wiki works' page; a village pump; and templates for flagging problems. To make things easy for our editors: templates for common things; template documentation; sandboxes and testcases for templates.

12.pdf (67kb)
abstract:
After years of talks about future plans for MetaPost 2.0, finally real progress is being made. This paper introduces a pre-release of MetaPost 2 that can optionally use IEEE floating point for its internal calculations instead of the traditional 32-bit integers.
