Eventz API
A Universal Software Law!
y = F(Y, e)
About Our Software
We present a Software Law:
y = F(Y, e)
• e is an event—something new happening.
• F is the only code—a function that applies the rules for e.
• y is the immutable data tuple that logs the event.
• Y is the immutable set of every previous y.
Real-Time Processing with RabbitMQ Pub-Sub
Eventz uses RabbitMQ pub-sub so that F functions can dynamically
subscribe to types of y that arrive as new e events.
• No need for direct function calls—F reacts automatically when
relevant events occur.
• Fully event-driven, enabling real-time processing without polling.
• Loose coupling—new functions can be added without modifying existing
code.

No More "Building the Wrong Software"
With Eventz, each department owns and manages its own e (events) and F
(functions).
No endless IT backlogs.No miscommunication between developers and business teams.Every stakeholder controls their own processes.
The End of the Requirements Nightmare
Traditional software development obsesses over Requirements—trying to capture every possible need upfront, locking projects into rigid structures that may not match reality.
With Eventz, Requirements are just e and F, as stated by stakeholders.
• e captures the real-world event—what actually happens.
• F applies the organization’s rules to process it.
That’s it. No speculation, no misinterpretation—just actual events and functions, continuously refined by the people who use them.
F is Technology Agnostic
Unlike traditional software, where choosing a platform locks you in, F can be
written in any technology that suits the task.Python, Java, C++, R—
whatever fits the function.Need high-performance computing? Use specialized libraries.
Want machine learning? Write F in TensorFlow or PyTorch.
Eventz doesn’t dictate technology. It just makes software work.
Your Calendar—Always There, No Internet Required
Ever noticed how Google Calendar goes blank without an internet connection?
That’s because it depends on a database that isn’t local.
But what if your Calendar was just data tuples—always available, never lost?
With y = F(Y, e):
• e is a new meeting request.
• F checks for conflicts and updates the schedule.
• y logs the new event.
• Y is the immutable set of every previous y—every appointment ever
made.
With y = F(Y, e):
• F checks for conflicts and updates the schedule.
• y logs the new event.
• Y is the immutable set of every previous y—every appointment ever made.
Payroll—From 9 Years of Work to 3-Second Reconciliation
But y = F(Y, e) processes nine years of payroll in seconds:
• F applies the articles of the union contract to calculate pay, overtime, and deductions.
• y logs the updated financials.
• Y is the immutable set of every previous y—every timecard and payroll entry ever recorded.
The AI Angle: Omniscience by Design
Notice that an argument of F is Y—which means AI sees everything
that ever happened.
AI thrives on historical data, context, and patterns, and Eventz naturally
provides all of it.
No need to query a database or engineer a data pipeline—just ask F
Too Simple to Fail.
With Eventz, software is no longer tangled in databases, APIs, and middleware.
It’s just functions and immutable events—fully controlled by the people
who actually use them.
And you believed that computing had to be complex. Nope. �
