An alternate history imagines IPv4 evolving into IPv4x: 128-bit addresses layered under 32-bit IPv4, preserving compatibility with existing networks. The first 32 bits remain, the extra 96 sit in the body; a flag marks IPv4x packets; IPv4 owners obtain the 96-bit subspace. RFC 1996 formalized it; MIT and others deployed it gradually; unused /8s were reserved for IPv4x. By 2006 IPv4 exhausted; NAT and CGNAT shaped networks; P2P flourished; 2016 the tipping point toward IPv4x; 2020 pandemic showcased benefits. In reality, IPv4x never happened; IPv6 became the upgrade path. SixGate envisions a bridge.

DDR4 initialization evolves through four phases: power-up/initialization, ZQ calibration (tunes 240Ω DQ network using an external reference to set drive and termination), VrefDQ calibration (internal VrefDQ for POD termination set via MR6), and Read/Write Training (align CK/DQS and determine per-DRAM delays). Training uses: Write Leveling, MPR Pattern Write, Read Centering, Write Centering. Periodic calibration (ZQCS and Read Centering) may be run to cope with voltage/temperature changes. On completion, the DIMMs enter IDLE and become ready for operation.

Apple’s MacBook Neo targets the sub-$1,000 market with a $599 starting price and emphasizes repairability. Its modular design makes internal components easier to replace than in recent MacBooks, and the keyboard is a separate top case rather than a fixed unit. Battery replacements are cheaper ($149), and accidental-damage fixes cost less under AppleCare+. Parts aren’t listed yet, but are expected to be cheaper than higher-end MacBooks, aiding schools, businesses, and accident-prone users.

Researchers show aging gut microbiome shifts trigger gut inflammation that dampens vagus nerve signaling to the hippocampus, contributing to cognitive decline. In mice, sharing microbiomes between young and old or transplanting old microbiomes into young impairs memory; conversely, germ‑free old mice retain memory, and activating the vagus nerve or treating with antibiotics restores young‑like memory in aged animals. They identify Parabacteroides goldsteinii as rising with age and linked to inflammatory metabolites that suppress the vagus–hippocampus axis. Modulating the gut microbiome or peripheral nerve activity may offer a way to combat age‑related cognitive decline in humans.

Fungi are crucial to life—building soils, sequestering ~13 billion tons of CO2 annually, and underpinning a $55 trillion economy—but remain poorly understood, with only about 155,000 described of perhaps 2–12 million species. Most plants rely on mycorrhizal networks that boost nutrient and water uptake and carbon storage. Conservation efforts (SPUN, Underground Explorers, FUNDIS) and recent pledges push to recognize fungi on par with plants and animals, signaling a growing global “fungal awakening.”

Tim Straubinger explains full-spectrum photography using a modded Canon EOS Rebel T6 with a hot-mirror filter and an 850 nm infrared low-pass filter to capture near-IR. Daytime scenes show pink-tinted foliage, dark skies, and altered shadows; infrared reduces haze for landscapes. Close-ups reveal translucent leaves and color shifts. Indoors, halogen, sodium, and LED lighting plus security cameras emit infrared, producing pink, glow-rich images. He notes focus challenges and previews future explorations with selective filters and ultraviolet.

Iran claimed an underwater-drone attack on two tankers anchored near Basrah, Iraqi waters. The Safesea Vishnu (73,976 dwt, US Safesea Group) and Zefyros (50,155 dwt, Greece’s George & Vassilis Michael family) were left ablaze; at least one crew member died and 38 foreigners were rescued as Iraqi port operations were suspended. The incident occurred about five nautical miles south of Basrah; UKMTO urged caution. Separately, Maersk-operated Source Blessing was struck by a projectile north of Jebel Ali; all crew safe and no environmental impact reported. The Gulf crisis widens.

Indirection in Rust async code isn’t inherently costly; extracting a few lines into a separate async function rarely affects performance in release builds, as compilers often inline small calls and the workload is dominated by I/O, locks, or allocations. Real concerns are maintainability, readability, and cognitive load. Measure with benchmarks and profilers; inline or extract only after a real problem is proven. Favor clear abstractions and testability, letting the optimizer handle the rest.

Atlassian plans to lay off about 1,600 employees (roughly 10%) to fund AI investments, though CEO Mike Cannon-Brookes says AI won’t replace people. Severance costs are estimated at $225–236 million, with cuts to complete by Q4 FY, mainly affecting software staff in the US, Australia, and India. CTO Rajeev Rajan is stepping down. The stock has fallen over 50% this year amid SaaS fears. Atlassian cites cloud growth and ~5 million monthly active users of its AI tool Rovo, but the company has been unprofitable since 2017.
