CPython's reference counting remains core, but hot-loop overhead is reduced by new optimizations. A new bytecode, LOAD_FAST_BORROW, loads locals without incrementing refcounts. It uses static lifetime analysis to borrow values on the stack; borrowed values must be consumed in the same block, or converted to strong refs if they may escape. The analysis uses control-flow graphs and abstract interpretation to identify safe LOAD_FAST{_LOAD_FAST} cases. JIT optimizations are loop-focused, optional, and trigger after ~4000 iterations. The work is likened to Rust lifetimes.

Flint, a Singapore-based company, says its cellulose-based, PFAS-free paper batteries are in production and will be offered to select strategic partners. The rechargeable, non-toxic, non-flammable cells use water-based manufacturing to cut reliance on lithium, nickel, cobalt, and lead. Production is in an 8,000+ sq ft facility in Singapore, with two product lines to be shown at CES 2026. Flint is expanding pilots with global brands (including Logitech), exploring European manufacturing, and developing a solid-state derivative for higher-density apps, following a US$2M 2025 raise.

Ken-ichi Ueda explains his departure after 18 years, citing a leadership that misdirected iNaturalist and ignored staff input. He argues for a two‑product approach—Seek for casual users and iNaturalist for enthusiasts—rather than one all‑purpose app. Leadership repeatedly shifted priorities, stifling the mobile team, and the buyout offer after staff attrition (about 30%) underscored governance failures. The Google AI grant debacle highlighted deeper problems. He plans to keep working on natural history software, pursue decentralization, and urges more user and board accountability, while considering future roles outside the current organization.

An expired security certificate broke macOS Logitech apps Logi Options+ and G Hub, causing them to fail to launch and reset device settings. Logitech released patches with an updated certificate, but the updater is also broken, so users must manually install patched versions. If apps weren’t uninstalled, settings should return after patching. Patches support macOS 13 Ventura, 14 Sonoma, 15 Sequoia, and 26 Tahoe; fixes for older macOS versions will come later.

Amjad Masad, Palestinian-born founder of Replit, was branded a 'terrorist sympathizer' in Silicon Valley after Gaza-related comments. Despite backlash, Replit pivoted to AI coding tools, launching an AI agent and, in 2024–25, raising $250M at a $3B valuation. Masad remains outspoken on Palestine, attracting both support and investor pushback, while Saudi Arabia’s PIF-backed partnerships and enterprise deals (Atlassian, Zillow) helped the company grow. He had previously turned down a $1B GitHub offer. Masad seeks to democratize software creation worldwide and use his wealth to aid Palestine, amid competition in AI coding startups.

Tumblr was removed from Apple's iOS App Store after user-uploaded images of child sexual abuse were found on the platform. The app disappeared on 16 November, with Tumblr saying the illegal images slipped through its moderation filters because they weren’t in its known CSAM database. Tumblr said it immediately removed the content and that safeguarding on scaled platforms is challenging; it asked for the app to be re-listed but gave no date. The incident follows Tumblr’s history of lax moderation and previous scrutiny by Indonesia and South Korea.

Bose open-sourced the SoundTouch API as it phases out the line. After Feb. 18, 2026, SoundTouch Wi‑Fi speakers and soundbars will be dumb: no security or software updates, cloud connectivity, or app control. However, AUX/HDMI/Bluetooth will still work; AirPlay and Spotify Connect will remain, and AirPlay 2 can play the same audio on multiple devices. The SoundTouch app will auto-update on May 6, 2026 to support locally operating functions, with a workaround for saving presets. The move aims to reduce e-waste and let users keep using devices, though some features are lost and customers are unhappy.

John Gruber discusses the New York Times’ frame-by-frame, three-angle analysis of Renee Good’s murder by an unnamed ICE agent in Minneapolis, rejecting Trump/Noem’s self-defense/terrorism framing and labeling the act as murder. He highlights bystander Caitlin Callenson’s near-field footage (posted by Minnesota Reformer) that captures the shooting and the officer’s flight, noting her courage and its role in identifying the officer as Jonathan Ross. Gruber emphasizes the danger of documenting such events and honors Callenson’s defiant, clarifying footage.

Security researcher demonstrates bypassing NVIDIA Tegra X2 secure boot on Magic Leap One and Tesla Autopilot hardware. Starting from a secured headset, they exploit the bootloader via USB, perform fault injection to dump the BootROM, and uncover an unpatchable USB recovery vulnerability affecting all Tegra X2s. They exploit flaws in NVIDIA’s Fastboot (SparseFS unpacking) and kernel DTB loading to gain persistence, then achieve code execution at the highest privilege level. The exploit also applies to Tesla Autopilot hardware. Speaker: Elise Amber Katze.

ChatLocal is a location-based chat app where you load perimeters around places to access chat rooms. You can contribute while inside a perimeter, search places to create or load perimeters, view top chat rooms, and use a heat map of favorite places. If no geofence exists, you can create one with an embedded geofence creator. Features include anonymous mode and place-based chats globally. An early-2026 app release is planned; it originates from LocalVideo, with a LinkedIn story reference; Terms of Service and Privacy Policy apply.

Protests sweep Iran as landline and internet access are cut in many cities. Eyewitnesses report nationwide demonstrations with security crackdowns. Video analysis of 463 clips from the first 10 days shows chants shifting from labor/strike calls to direct anti-Islamic Republic slogans and increasing calls for the return of the monarchy—Pahlavi— with mournful elegies and chants like "Death to the dictator" and "The Shah is coming home." Protests spread from Tehran to 91 cities, including universities; chants split between anti-regime and pro-Pahlavi lines. International reactions include Alinejad urging Starlink and U.S. figures signaling support for regime change.

Arm CPUs sometimes implement TSO; the standard Arm memory model is weaker, complicating x86 emulation. A patch series proposes making TSO switchable in Linux via prctl, so user-space can enable TSO where supported. Some CPUs (NVIDIA, Fujitsu) run TSO; Apple offers it as run-time opt-in. Maintainers Deacon and Marinas oppose upstreaming, warning it would fragment code and complicate portability. Alternatives include keeping it out-of-tree, enabling only in VMs or per-process, or shipping with downstream kernels. The discussion highlights a tension between hardware capabilities and kernel-wide portability.

Texas' Collin County court issued a temporary restraining order blocking Samsung from collecting TV viewing data via Automated Content Recognition (ACR) in Texas, citing deceptive enrollment, opaque disclosures, and consent that isn't informed; the court warned data could be accessed by the Chinese Communist Party and extended the TRO to Samsung officers and staff. One day later the judge vacated the TRO, saying it should be set aside; Samsung said the order was vacated on Jan. 6, with a hearing scheduled for Jan. 9. The lawsuit continues.

Aphex Twin and ex-Korg engineer Tatsuya Takahashi discuss their collaboration on the Monologue, focusing on microtuning, real-time scale editing, and the philosophy of standards versus musical feel. They trace tuning origins from 440 Hz, the value and challenges of microtuning, and the Monologue editor's ability to import/export Scala files; discuss sampling rates (48 kHz vs 31.25 kHz) and drift vs stability. They cover gear usage (Monologue, MS-20 kit, Poly-61M, Volcas, Cirklon), the creation of "Korg Funk 5," and the design process, constraints, and future possibilities, with Takahashi leaving Korg and reflections on creativity.

The article argues that PostgreSQL observability must be unified with application and infrastructure monitoring, not kept isolated. As systems scale, DB metrics reflect system-wide patterns and root causes; standard DB views are insufficient. It outlines a 'bridge' approach: shared time axis, common identifiers, unified storage, and integrated workflows for cross-signal analysis and causal diagnosis. It introduces pgX, Base14's PostgreSQL observability integration that brings deep DB metrics into the same data lake as traces, logs, and metrics to speed root-cause analysis and optimization. The next post will detail what pgX collects and visualizations.
