The unfolding energy shock is rattling global markets, raising the prospect of $150 oil, and forcing energy-dependent economies across Asia and Europe to scramble for alternatives.

We May Be Living Through the Most Consequential Hundred Days in Cyber History In the first four months of 2026, an unprecedented wave of cyberattacks occurred, including the wiping of Stryker’s global fleet across 79 countries, the hijacking of the wildly popular Axios npm package, and a 10-petabyte leak from a Chinese state supercomputer. The author points out a jarring disconnect: while the public discourse remains strangely fatigued and silent, there is quiet panic behind closed doors—highlighted by an emergency briefing between the Treasury Secretary and bank CEOs regarding thousands of zero-days discovered by Anthropic’s new Mythos model.

When using large language models for recommendation systems, passing raw numerical counts ruins the signal because the model processes digits as text tokens rather than magnitudes. By converting raw engagement counts into percentile buckets wrapped in special tokens (e.g., <view_percentile>71</view_percentile>), LinkedIn increased the correlation between popularity and embedding similarity 30x, offering a highly reusable pattern for safely encoding structured numerical data into transformer contexts.

OpenAI is pivoting its resources away from video generation tools like Sora to focus intensely on a new “Super App” designed to autonomously operate your computer and automate workflows. Company leadership revealed that a powerful new foundational model codenamed “Spud” is expected within weeks, aiming to push AGI boundaries by acting as a universal, agentic digital assistant rather than just a chatbot.

The landscape of AI-assisted programming is shifting rapidly as agentic workflows mature. In a recent InfoQ interview, David Heinemeier Hansson (DHH) shared his transition to an “Agent-First” development style, arguing that AI dramatically amplifies the value of senior engineers while signaling the end of the traditional programmer’s “golden age”. In the enterprise space, NetEase’s CodeWave platform is actively pushing back against chaotic “Vibe Coding” by advocating for a “Spec Driven” approach to bring control and maintainability to AI-generated code bases.

Story of the Week#

Global markets experienced severe whiplash as early-week optimism for an imminent end to the U.S.-Iran conflict quickly evaporated following President Donald Trump’s prime-time address vowing to strike Iran “extremely hard” over the next several weeks. The geopolitical escalation sent energy markets parabolic, with the Strait of Hormuz effectively closed and physical Brent crude cargoes skyrocketing past $141 per barrel—its highest level since the 2008 financial crisis. Energy analysts are warning that if the war extends beyond April, the global economy faces a catastrophic loss of over 600 million barrels of oil, forcing a brutal transition from supply anxiety to outright demand destruction and rationing.
