People often ask if they should use another tool than Google Analytics. In this presentation, I am showing a few ways to work with the GA API to obtain some compelling visualizations. Here are the eight types analysis we are proposing to go beyond the Analytics functionality: - Box plots & Histograms - Rolling Averages - Decomposing & Forecasting traffic - Growth over traffic - Bubble chart overviews - Pareto analysis - Bars & Lines - Multi-channel analysis Most of our visualizations are built with the help of R, Tableau and D3.js

The document discusses probability distributions and their natural parameters. It provides examples of several common distributions including the Bernoulli, multinomial, Gaussian, and gamma distributions. For each distribution, it derives the natural parameter representation and shows how to write the distribution in the form p(x|η) = h(x)g(η)exp{η^T μ(x)}. Maximum likelihood estimation for these distributions is also briefly discussed.

Transactional Outbox & Inbox Patterns.pptxMaysam Mousa

This presentation provides a comprehensive overview of the Transactional Outbox Pattern and the Inbox Pattern, two essential techniques for ensuring reliable and consistent communication in distributed systems. We start by clearly outlining the problem these patterns aim to solve—namely, maintaining data consistency between databases and message brokers in event-driven architectures. From there, we delve into what the Outbox Pattern is, how it works under the hood, and how it guarantees message delivery even in the face of failures. The presentation then shifts focus to the Inbox Pattern, explaining its role in ensuring idempotency and preventing duplicate processing of messages. Each concept is explained with simple language, diagrams, and a logical flow that builds a solid understanding from the ground up. Whether you’re an engineer building microservices or just exploring distributed system patterns, this talk provides clarity, practical insights, and a helpful demo to see the patterns in action. Topics Covered: * Problem Statement * Transactional Outbox Pattern * How It Solves the Problem * Internal Mechanics * Delivery Guarantees * Inbox Pattern Explained * Internal Workflow * Conclusions & Further Reading * Demo
