History

edit

On 29 May 1999, the first SLOCs of the Polit OS shell has been written by Ivan Kozak (Ukrainian: Іван Козак), a Ukrainian programmer, at the time he being a student of KPI, later a student of KNU in the field of Cybernetics.[1][2][3][4][5]

 
Halcyon used as service name for Polit OS, and blue bird as logo

On 6 January 2001, a new developer, nicknamed 'Cyberhead', joined the Polit development.

During Sumer 2001, source has been fully rewritten from Turbo Pascal 5.5 to Borland Pascal 7.

On 15 January 2002, author of Polit has been hosted to talk about Polit OS at the «Night zone online» (Ukrainian: Зона ночі online) late night TV-show on the Novy Kanal.[6]

On 4 July 2002, CaesarAgency, one of Ukrainian domains registrators, gifted Polit with a free hosting and polit-os.org.ua domain.[7] Polit named as "the first Ukrainian operating system" because it has Ukrainian interface mimiced to Microsoft Windows UI.

On 21 August 2002, Yury Benesh,[8] author of the StormDOS shell in Assembly,[9] ported Polit to Virtual Pascal, which resulted in a small improvements of execution speed and decreasing size of distribution files. Source code and both 16-bit and 32-bit binary builds of this port available on the official Polit OS website.

On 30 August 2005, Ivan Kozak released the last version of the Polit shell, commemorating it to the 14th Anniversary of the Independence of Ukraine. It has a new the "Blue Bird" default theme.

During all of the time of active development, there was at least 6 contributors (from Kyiv, Kharkiv, Odesa and Belarus), including author, who joined the Polit OS development.[6]

Features

edit

Polit distributed in a form of zipped folder and floppy disk IMG-file, and could be launched from DOS (MS-DOS, FreeDOS) and Windows 95/98/M on PC or run inside emulators and virtual machines (DOSBox, DOSBox-X, VirtualBox).[10][11]

Pros

edit

Cons

edit
  • Impossible to launch external DOS software, except of own built-in software and software written for Polit.
  • Bad support for hardware components and devices due to lack of drivers.
  • Limited number of ready to use software (but new software could be created by users with a knowledge of Pascal).
