Phoronix's Michael Larabel writes: An interesting anecdote from this month's Linux Plumbers Conference in Tokyo is that Meta (Facebook) is using the Linux scheduler originally designed for the needs of Valve's Steam Deck... On Meta Servers. Meta has found that the scheduler can actually adapt and work very well on the hyperscaler's large servers. [...] The presentation at LPC 2025 by Meta engineers was in fact titled "How do we make a Steam Deck scheduler work on large servers." At Meta they have explored SCX_LAVD as a "default" fleet scheduler for their servers that works for a range of hardware and use-cases for where they don't need any specialized scheduler. They call this scheduler built atop sched_ext as "Meta's New Default Scheduler." LAVD they found to work well across the growing CPU and memory configurations of their servers, nice load balancing between CCX/LLC boundaries, and more. Those wishing to learn more about Meta's use and research into SCX-LAVD can find the Linux Plumbers Conference presentation embedded below along with the slide deck (PDF).

An anonymous reader quotes a report from MarketWatch: ServiceNow announced a deal to acquire cybersecurity company Armis on Tuesday, marking a new milestone in the software giant's artificial-intelligence business strategy. The $7.75 billion all-cash transaction is part of ServiceNow's goal of advancing governance and trust in autonomous AI agents, and the company's largest transaction to date. "The acquisition of Armis will extend and enhance ServiceNow's Security, Risk, and [Operational Technology] portfolios in critical and fast-growing areas of cybersecurity and drive increased AI adoption by strengthening trust across businesses' connected environments," the company wrote in a press release. While ServiceNow built its foundation IT service management products, the company has positioned itself as an "AI control tower" that orchestrates workflows across HR, customer service and security operations. Organizations today are operating in increasingly complex environments, with assets spanning from laptops and servers to smart grid devices, Gina Mastantuono, chief financial officer of ServiceNow, told MarketWatch on Tuesday. "But at the same time, cyber threats are becoming more sophisticated and more complex," she added. ServiceNow's Security and Risk business crossed $1 billion in annual contract value earlier this year, and the Armis acquisition is expected to triple ServiceNow's market opportunity in the sector. Armis currently has over $340 million in annual recurring revenue, with growth exceeding 50% year-over-year, according to the press release. The Armis acquisition would allow ServiceNow to create an "end-to-end proactive cybersecurity exposure and operations stack that enables enterprises to see, decide and act across a business' entire technology footprint," Mastantuono said.

Here are some of the new Laowa lenses Venus Optics will announce next year (2026):

  • Laowa FF 45mm f/2.8 ultra macro full-frame 1-5X APO (11 elements in 9 groups)
  • Laowa FF 17.5mm f/1.7 ultra macro full-frame 5-10X APO (17 elements in 12 groups)


Specifications:

  • Full-range parfocal design throughout zooming (means the focus will not change as you increase magnification)
  • Coaxial illumination (means light goes through the lens, hits the surface, and comes back; the lens acts as a condenser and an objective – suitable for inspection)
  • Covers high magnification zoom from 1:1 to 10:1, filling the gap between a traditional macro lens and a microscope
  • Longer working distance (40.35mm/22.5mm) facilitates lighting setup
  • Adopts apochromatic (APO) optical design to effectively eliminate chromatic aberration, resulting in sharp images and accurate colors
  • Full-frame lenses compatible with multiple mounts (E/Z/L/F/RF/EF)
  • Meets the image needs of scientific research and commercial applications

Laowa FF 14-60mm T3.6 stereo zoom lens:
