TECH

1. Four-hour batteries beat new gas peakers on cost — Wood Mackenzie modelling found them cheaper across all 43 assessed markets. This strengthens the economic case for storage in peak-power systems. https://gastopowerjournal.com/news/energy-storage/four-hour-batteries-now-beat-gas-peaking-plants-on-cost-globally/
2. AI agents completed all tested OT attack scenarios — Booz Allen’s lab tests showed frontier models moving from network access to physical industrial actions. Critical-infrastructure cyber defenses need to assume much faster attacks. https://www.theregister.com/security/2026/10/11/ai-systems-are-fully-capable-of-carrying-out-nightmare-attacks-against-infrastructure-and-nobodys-ready/5302450
3. Korean researchers controlled 2D semiconductor crystal growth — Their oxygen-based process achieved single crystals at 397 of 400 sites in testing. It could help make atomically thin chip materials manufacturable. https://www.theregister.com/science/2026/10/11/researchers-work-out-how-to-control-2d-semiconductor-growth-for-future-chips/5301666
4. Linux adds an AMD TLB-erratum workaround — Linux 7.3-rc7 will protect affected Zen systems running older microcode. It prevents stale memory-translation entries from causing incorrect behavior. https://www.phoronix.com/news/Linux-WA-TLBI-Erratum-1718
5. Microsoft contributes a Hyper-V IOMMU driver to Linux — The planned Linux 7.4 driver enables in-kernel DMA protection and device assignment for guest VMs. It improves virtualization security and hardware access on Azure-style systems. https://www.phoronix.com/news/MS-Paravirt-Hyper-V-IOMMU

FINANCE / POLITICS

1. Ukraine says Russia violated the announced energy ceasefire — Zelenskyy cited a strike on a Kharkiv thermal plant and asked Washington to enforce any deal. Energy infrastructure remains central to the war and fuel-market risk. https://www.investing.com/news/commodities-news/ukraine-accuses-russia-of-violating-trumps-energy-ceasefire-as-eu-imposes-new-sanctions-4943687
2. US senators urge reversal of the Russian diesel plan — Six bipartisan senators opposed planned purchases intended to ease high fuel prices. The proposal links domestic inflation pressure to sanctions policy. https://apnews.com/article/93fa63c8a88e538f1456e7d448fc550d
3. Vår Energi cuts its 2026 production outlook — The company now expects 390,000 barrels of oil equivalent per day after operational problems at several assets. It is a near-term signal for Norwegian petroleum output and investors. https://e24.no/boers-og-finans/i/Vgjzx6/nedgang-paa-oslo-boers-oljeaksjer-faller
