FireViston TV: Android App & Streaming Server for the Living Room

Live Project: tv.cadnative.com What Is FireViston TV? FireViston TV is a full-stack streaming solution designed for the modern living room. It consists of two parts that work in tight coordination: FireViston TV Android App — a native Android/Android TV application that delivers a polished, remote-friendly viewing experience. https://github.com/akshaynikhare/FireVisionIPTV/releases FireViston TV Server — the backend streaming infrastructure that powers content delivery, user management, and playback control hosted at tv.cadnative.com Together, they form a complete, self-contained streaming platform. The Android App Built for the 10-Foot Experience The FireViston Android app is designed for television screens — large fonts, d-pad navigation, and a layout that works from across the room. No pinching, no scrolling hunts, no mobile-style UI crammed onto a 55-inch display. Smooth Playback Video streaming requires more than just playing a file. FireViston handles adaptive bitrate streaming, buffer management, and codec compatibility to ensure smooth playback across the broadest range of Android TV devices — from budget sticks to high-end smart TVs. Content Discovery A clean, browsable content grid lets users find what they want quickly. Categories, search, and a "continue watching" row reduce friction from intent to playback. The Server Backend Reliable Infrastructure The FireViston server at tv.cadnative.com manages content ingestion, transcoding pipelines, and delivery. It's built to handle concurrent streams without degrading quality for any individual viewer. API-Driven Architecture The Android app communicates with the server through a REST API, making the backend flexible enough to support additional clients — web players, other mobile platforms — without rewriting core logic. User & Session Management Account creation, authentication, playback progress sync, and device management all happen server-side. Users can pick up on any device exactly where they left off. W

Exactly-Once Semantics in Kafka: Promise vs. Reality

"We're using Kafka with exactly-once semantics, so we don't have to worry about duplicates." I've heard this in architecture reviews, design docs, and postmortem explanations. It represents a misunderstanding of what Kafka's exactly-once guarantee actually covers, and the gap between the promise and the reality has caused real production incidents. What Kafka's Exactly-Once Actually Covers Kafka's exactly-once semantics (EOS), introduced in 0.11.0, operates at two levels: Producer idempotence ( enable.idempotence=true ): The producer assigns each message a sequence number. The broker deduplicates messages with the same producer ID and sequence number. This prevents duplicates caused by producer retries — the message lands in the Kafka partition exactly once, regardless of retry count. Transactions ( transactional.id ): Allows a producer to write to multiple partitions atomically. Either all writes commit or none do. Combined with isolation.level=read_committed on consumers, readers only see committed transactions. Together, these give you exactly-once message delivery within the Kafka cluster. What Exactly-Once Does Not Cover Here's the boundary that engineers miss: Kafka's exactly-once guarantee is scoped to the Kafka cluster. The moment your consumer does anything outside Kafka — writes to a database, calls a REST API, publishes to a cloud queue — you're outside the transaction boundary. Consider a typical consumer: consumer . poll ( records ); for ( record : records ) { database . save ( process ( record )); // External write — outside Kafka transaction } consumer . commitSync (); If the application crashes after database.save() but before commitSync() , Kafka re-delivers the message. The consumer reprocesses it. The database now has two writes for the same event. Enabling producer idempotence on the consumer's Kafka writes does not fix this. The Patterns That Actually Give You End-to-End Safety Idempotent Consumers Design consumer processing logic to be idempote
