Temporal's Rust SDK 1.0 demoed on custom ESP32 conference badges

·1 views

A developer created a demo to announce Temporal's Rust SDK 1.0 release at RustConf. The project involved running the SDK on Replay 2026 conference badges, which are ESP32-S3 based devices. These badges functioned as genuine Temporal Activity Workers, polling a cloud Task Queue and handling user input. The 'Durable Trivia' game demonstrated the SDK's capabilities, including heartbeating and activity completion on constrained hardware.

Bogotá apartment rental data reveals median price disparities across neighborhoods

Aptología released ten new open-data studies on Bogotá's apartment rental market based on October 2026 listings. The research shows median rents vary widely, from COP 1 million in Usme to COP 4.5 million in Chapinero. Furnished apartments cost nearly 23% more per square meter than unfurnished ones. Units that accept pets command a 7% premium, and higher-floor apartments are significantly more expensive.

PostgreSQL & Node.js Techniques Prevent Inventory Overselling

A common concurrency bug called the lost update problem can cause online stores to oversell limited inventory during high traffic. This occurs when multiple transactions read the same stock level before any of them update it, leading to inaccurate decrements. The article demonstrates the issue using a Node.js and PostgreSQL environment where 50 concurrent purchase requests compete for 10 items. It then presents three solutions: conditional atomic updates, pessimistic locking, and optimistic locking. The appropriate method depends on the specific level of data contention in the application.

Compose Multiplatform on iOS: Memory Pressure from Skia-Metal Rendering

A technical article analyzes performance issues in Compose Multiplatform apps on iOS devices with limited RAM. It explains how the framework's Skia canvas uses Apple's Metal API for rendering, independent of UIKit. The integration of native UIKit components creates boundaries that force expensive GPU context switches, increasing memory pressure. On devices with around 3GB of RAM, such as the iPhone XR, these compositing decisions can trigger memory spikes and cause dropped frames in production.

AI and IoT bridge data gaps for visibility in automotive manufacturing

Automotive manufacturing faces a visibility challenge due to operational data fragmented across multiple separate systems. This fragmentation hinders a unified, real-time view of factory operations, complicating tracking of vehicles, components, and processes. Technologies like AI, IoT, RFID, and real-time location systems can connect physical operations to digital systems. These technologies enhance traceability, improve tracking of assets across assembly stations, and support smarter production decisions.
