Azurpoly has released new screenshots and a development update for their Dassault Rafale add-on for Microsoft Flight Simulator, highlighting the addition of realistic wingtip smoke and physics-based flare systems. Simultaneously, Skyward Simulations detailed the upcoming Cessna Citation Sovereign+, emphasizing its highly interactive cockpit, advanced electrical system simulation down to the PCB level, and refined flight models. Both updates focus on increasing the fidelity of flight dynamics and avionics logic to provide a more authentic simulation experience for users.

Japan has officially relaxed decades-old restrictions on arms exports, allowing it to sell lethal weapons to 17 allied nations including the US and UK for the first time since WWII. This policy shift marks a significant departure from the country's post-war pacifist identity, driven by Prime Minister Sanae Takaichi's assertion that no single nation can ensure security alone in the current geopolitical climate. While a ban on sales to conflict zones remains, authorities have introduced exceptions for 'special circumstances' amidst rising regional tensions involving China and North Korea.

Japan has officially scrapped its postwar ban on exporting lethal weapons, marking a significant shift in its pacifist policy to strengthen its defense industry against regional threats from China and North Korea. The new guidelines allow the sale of advanced equipment like fighter jets and destroyers to 17 partner nations, including Australia and the Philippines, while maintaining strict screening to avoid supplying countries at war. This move aims to build a resilient industrial base and deepen military cooperation, though it faces criticism from opponents who argue it violates the constitution and could increase global tensions.

The C# Dev Kit team replaced complex C++ native Node.js addons with C# and .NET Native AOT to reduce build friction and dependency overhead. This approach leverages N-API to allow C# code to produce shared libraries that Node.js can load directly without requiring Python or legacy build tools. The article details the implementation of P/Invoke, string marshalling, and entry point registration to enable seamless interoperability between .NET and JavaScript.

This tutorial provides a complete Python implementation for deploying the Qwen 3.6-35B-A3B multimodal MoE model, covering advanced features like thinking traces, tool calling, and session persistence. The code demonstrates dynamic GPU memory management, quantization strategies, and the integration of retrieval-augmented generation (RAG) for practical workflows. It serves as a technical guide for developers looking to prototype robust AI applications using modern large language models.

Kevin Warsh is scheduled to appear before the Senate Banking Committee for his Federal Reserve chair nomination, facing scrutiny over his financial transparency and alignment with President Trump's demand for interest rate cuts. The hearing is complicated by rising inflation linked to the Iran conflict and a Justice Department investigation into current Chair Jerome Powell, which may delay the nomination vote. This potential leadership transition could create an unprecedented overlap where Warsh and Powell serve simultaneously, raising concerns about market stability and Fed independence.

In response to escalating war pressures, Iran has granted its field commanders greater autonomy over militias operating in Iraq, allowing them to conduct operations without direct approval from Tehran. This decentralization marks a significant shift from previous centralized command structures, driven by the need to preempt complaints from Iraqi Kurdish authorities and adapt to the aftermath of recent conflicts. The move complicates U.S. efforts to curb attacks on American assets, as these groups now function with increased independence while remaining embedded within Iraq's state security apparatus.

Oil prices dipped and Asian shares mostly rose on Tuesday as uncertainty persisted regarding US-Iran negotiations aimed at ending the regional war. Despite a scheduled ceasefire deadline, tensions remain high following the seizure of an Iranian-flagged ship, keeping investor sentiment cautious about potential supply disruptions in the Persian Gulf. Meanwhile, strong corporate earnings from US companies and resilient consumer spending continue to support market stability despite the geopolitical backdrop.
