This tutorial demonstrates building a stateful engineering copilot using Letta, an AI framework that moves beyond simple prompt-based chat to include inspectable core memory blocks and shared state. The article details how to create agents with persistent memory for project tracking, semantic retrieval, and custom tools, while also enabling multi-agent collaboration through shared block access. This approach allows for deterministic risk estimation and portable agent workflows suitable for complex engineering tasks.

AionSky Studios has released AliveGrass, a new scenery utility for X-Plane 11 and 12 designed to enhance visual realism by dynamically adjusting grass color, density, and species based on environmental factors. The tool features automatic seasonal changes, terrain-aware placement that avoids roads and water, and performance optimizations that reportedly cause only minor FPS drops even on mid-range hardware. This release offers flight simulation enthusiasts a more authentic ground experience with regional vegetation variety.

BlueBird Simulations has released a highly detailed Boeing 757-200 add-on for Microsoft Flight Simulator 2020 and 2024 after a five-year development period. The package features an authentic flight management system, complex hydraulic simulations, and advanced Wwise 3D audio architecture developed in collaboration with Boris Audioworks. Priced around €71 or $80, the aircraft requires significant hardware specifications including an RTX 2080 and 16 GB of RAM to run properly.

SkyNexus has launched a free, browser-based Electronic Flight Bag (EFB) compatible with Microsoft Flight Simulator, X-Plane, and Prepar3D. The tool integrates with SimBrief operational flight plans to provide detailed performance calculations for major aircraft like the A320 and Boeing 737, utilizing live METAR data and NOAA GFS weather models without requiring a premium subscription. This release offers simulator pilots access to professional-grade briefing features, including turbulence overlays and runway exit predictions, entirely within a web browser.

MK Studios has released an early-access EFB app called MK Airport for Microsoft Flight Simulator 2024, allowing users to control their custom scenery's jetways and gate logic immediately. The tool integrates with the default simulator interface to manage aircraft docking sequences while offering features like SimBrief plan imports and customizable VDGS displays. This release provides simmers with advanced ground operations capabilities without requiring a wait for the official Contrail App launch.

Israeli forces have demolished homes and displaced approximately 2,000 Palestinian families in Hebron following an attack on a checkpoint that killed two soldiers. Prime Minister Benjamin Netanyahu authorized the operation as collective punishment for the gunmen's neighborhood, while far-right ministers called for even broader campaigns similar to those in Gaza. Local officials describe the situation as driven by upcoming elections, with residents forced to flee their properties and vehicles left behind.

Serbia faces a pivotal parliamentary election where student-led opposition candidate Ilija Srdanović challenges long-serving leader Aleksandar Vučić in a tight race. The Student List, formed from anti-corruption protests following the Novi Sad railway station collapse, fields 250 non-political candidates ranging from academics to engineers. This contest highlights a clash between Vučić's established infrastructure-focused governance and the opposition's vision for civil society freedoms and transparency.

Violent clashes erupted in Paris on Saturday as protesters threw fireworks and objects at police forces, prompting a response involving tear gas and water cannons. Approximately 70,000 officers were deployed across France to manage demonstrations that saw an estimated 400,000 participants, resulting in nearly 1,000 arrests. The Interior Ministry indicates that the unrest shows no immediate signs of easing.

Ukraine's Defence Minister confirmed that Starlink connectivity has been restored to stable speeds exceeding 400km/h after a recent dispute involving US President Donald Trump and Elon Musk allegedly imposed network limits. This restoration is critical for Ukrainian military operations, specifically enabling drones and logistics in remote battlefield areas where the satellite network serves as a primary communication link. The issue arose amidst broader diplomatic tensions regarding US sanctions on Russia and strikes on Russian oil infrastructure.

Ukrainian President Volodymyr Zelensky reports unexplained restrictions on Starlink and Starshield services affecting military operations, while US officials and Elon Musk provide conflicting explanations for these limits. The networks utilize a constellation of 10,000 satellites to maintain critical communications for drone operators and remote forces in the conflict zone. This dispute highlights the complex geopolitical dynamics surrounding private space infrastructure used in active warfare.
