Portfolio excerpts

  • Software products

    First of all, I have designed and built a number of proprietary client-server applications based on customer demands and deployment environment specifics. Naturally these are considered business secret and it wouldn't be appropriate to exhibit the details. See following freeware products for reference:

    • B-Cup XP, Windows XP and 2003, service with control panel
      Simple, fast and compact automated backup program, positively reviewed on freeware sites and by users all over the world
    • Dynamic Log Viewer, Windows 2000 and later, user mode application
      Inspired by linux tools, provides way for watching current state of processes or systems that log their status into plain log files. Used by developers in number of environments.

  • Middleware and C++ libraries

    • EXT C++ Library, details and project progress: http://sourceforge.net/projects/ext/
      Set of various useful C++ classes, templates and macros that extend functionality provided by ISO C++ and standard C++ library. The aim of the EXT library is to provide a range of lightweight language and library utilities.
    • Brace C++ library details and project progress: http://sourceforge.net/projects/brace/
      Brace is a comprehensive C++ template library that parse, organize and serialize string-based human-readable hierarchical data. The contained format itself is easier to edit and maintain than XML, yet similar in philosophy and already widely used (in plenty of dialects).
    • eXtendable Binary library details and project progress: http://sourceforge.net/projects/xbinary/
      The XB Library is an effort to implement a library for manipulation with universal file format that would match the requirements of so called Binary XML. The XB data format allows fast and compact, yet still robust enough, serialization of trees of any arbitrary data.
    • Z4 storage library
      Compressed filesystem storage library with access caching, constant read/write access times and encryption support. Total Commander plugin is also available.

  • Web applications and presentations

    • www.ringos.cz
      XHTML 1.1 valid presentation, CSS styled, clean and readable code, simple but professional design
    • www.rksen.cz
      XHTML/CSS, webdesign, implementation, dynamic content (PHP), proprietary content management system
    • www.tds.cz
      XHTML/CSS, ordinary corporate webpage design, dynamic content (PHP), simple content management
    • www.intextr.cz
      XHTML/CSS, designed an early version of company homepage

  • Games and eye-candy applications

    • The Matrix Trilogy Screensaver, for official webpage see http://www.matrixscreensaver.150m.com/
      Project that aims to become the best The Matrix code simulation available as freeware.
    • Shoot 'em, Windows 2000 or newer
      Very simple and straightforward shooter game. What makes it unique is that its 3D graphics is drawn in full colors in text mode, similar to ASCII art.
    • Space 2004: Solar System, non-interactive real-time animation
      7 minutes long demo, made for Czech 3D Open Contest. Realistic visit of all planets in our Solar system. Silver in overal rating.

  • Talks and articles

    • C++0x, Game Developer Session 2008, Brno
      An informal talk about upcomming revision of the C++ programming language standard held at conference of game developers.
      http://gds.ceske-hry.cz/game-developers-session-2008/program/45
    • Standard pro zápis kódu v jazycích C a C++
      List of rules and recommendations for C and C++ coding, including rationale for every rule, that I was tasked to prepare for my team. Guided by recommendations of highly valued C++ experts (listed inside), but also clearly biased by my experience and local specifics. Publicaly available here with consent of my employer. Only Czech language version is available.
    • Obecná schémata ochrany kódu
      Originally written for Ceske-Hry.cz magazine the paper covers basics of different executable code and data protection schemes and techniques. Only Czech language version is available.
    • PC Svět (no longer existing www.pcsvet.cz)
      I wrote more than sixty technical articles published on the PC Svět magazine website. The papers were mostly focused on C++ programming language, programming techniques and software development in general.
