1979
🃏 Fortran — IBM 360 (Punched Cards!)
The very first program by Danko Josić: a steam properties diagram calculator, written in Fortran on an IBM 360 mainframe using punched cards. Where the coding journey began — 47 years ago.
1984
🎮 Commodore 64 BASIC
Original version written on an 8-bit Commodore 64 (64 KB RAM). Pure mathematical algorithms for planetary positions (Sun through Pluto) and the Placidus house system. A true software engineering legend.
~1985
💻 Turbo C — MS-DOS
Port from BASIC to Borland Turbo C. Compiled native executables for the IBM PC platform.
~1990
💻 Quick C — DOS/Windows
Microsoft Quick C port with further optimisation for the evolving PC ecosystem.
~1993
💻 Microsoft C — DOS/Windows
Professional-grade Microsoft C compiler. Continued cross-platform compatibility work.
~1996
📱 Watcom C — Palm Pilot
Remarkable port to the Palm OS PDA. Memory-constrained embedded-systems optimisation — astrology in your pocket.
1998–2000
🌐 PHP 3/4 — Web
Transition to the internet era. Apache/Linux web server, HTML forms, multi-user support for the first time. The calculation engine crossed onto the web unchanged.
2000–2025
🌐 Modern PHP Evolution
User authentication, MySQL database, Bootstrap 4 responsive UI, jQuery enhancements, session management, DST support.
2025
🔐 Security Modernisation
MD5 → bcrypt passwords, CSRF protection, environment-based config, XSS prevention, SQL injection defense (prepared statements). All security issues were in later additions, never in the original 1984 calculation engine.
2026
✨ Feature Expansion
Synastry, Composite Chart, Transits, Secondary Progressions, Solar Return, Lunar Return, Almanac suite (Ephemeris, Moon Phases, Retrogrades, Eclipses, Astro Calendar), Planetary Hours, Famous Charts, Zodiac gallery, Glossary. AI-powered chart synthesis across natal, synastry, composite, solar/lunar return, progressions, and Arabic Parts — personalized interpretations grounded in actual placements, cached cross-user for efficiency.

⚠ Core engine note:
The 1984 astronomical calculation code is mission-critical and has never been the source of security issues — it is pure mathematics with no user input. All security improvements (passwords, sessions, CSRF) addressed code added during the web era (1998–2000s).

✦ Astro Quote
Our modern science begins with astronomy. Instead of saying that man was led by psychological motives, they formerly said he was led by his stars. ... The puzzling thing is that there is really a curious coincidence between astrological and psychological facts, so that one can isolate time from the characteristics of an individual, and also, one can deduce characteristics from a certain time. Therefore we have to conclude that what we call psychological motives are in a way identical with star positions. Since we cannot demonstrate this, we must form a peculiar hypothesis. This hypothesis says that the dynamics of our psyche is not just identical with the position of the stars, nor has it to do with vibrations - that is an illegitimate hypothesis. It is better to assume that i is a phenomenon of time. ... The stars are simply used by man to serve as indicators of time... - Carl G. Jung in 1929
