EVi is a hard fork of Vim v9.1.2073 (Jan 2026) designed to avoid AI taint while extending Vim’s foundations. It retains Vi compatibility and adds features such as multi-level undo, syntax highlighting, command history, online help, spell checking, filename completion, block operations, and a GUI. Distribution is from Codeberg. The README for version 10.0 covers installation, documentation, and licensing (charityware, GPL-compatible); contributions are welcome. The project continues Bram Moolenaar’s Vim legacy with no AI integration.

Practical Guide to Bare Metal C++ explains how to use modern C++ (C++11) for embedded bare‑metal development, focusing on soft real‑time systems without heavy RTOS. It argues why C++ can outperform C via templates and code reuse, but warns about overhead from exceptions, RTTI and the standard library. It outlines a Device–Driver–Component architecture and an EventLoop model to handle interrupts and non‑interrupt contexts, with templates for generic peripherals, custom allocators, and logging. It also documents embxx/embxx_on_rpi libraries and concrete peripheral examples (UART, Timer, GPIO, I2C, SPI), startup/linker considerations, and offline builds.

TCXO failure in ThunderScope: 10 MHz output flat; PLL not locking. References showed a 10 MHz source but timebase ran at 10.665 MHz. After depackage, the crystal seemed fine; it resonated around 20 MHz, implying a divide-by-two in the driver. The root cause was a broken long bond wire from the controller die to the crystal, at the crescent bond interface, disconnecting the crystal. Ultrasonic cleaning during rework and bond-process issues were likely contributing factors; a second similar failure was reported, supporting sonication risk.

FT front-page montage of global headlines. Central threads: the Iran war’s economic impact (Kharg Island oil lifeline, which economies will pay the price) and U.S. strategy; market analysis (Goldman on hedging corporate loans); tech funding (Yann LeCun’s startup raising over $1bn). Also covers diversity in governance, European startup news, Venice food trends, and other business, politics, and culture briefs, plus paywall prompts.

howisFelix.today (FxLifeSheet) is Felix Krause’s decade-long quantified-self project tracking 100+ data types daily, yielding ~380k entries from RescueTime, Swarm, Apple Health, weather, and manual inputs. It runs on a single self-hosted Postgres DB and offers 48 open graphs with privacy-conscious daily snapshots. Data are entered via a Telegram bot; the aim is to explore how city, sleep, weather, and routines affect fitness, mood, and social life. In 2025 he stopped collecting data but kept the site and invites others to fork their own version.

Baochip-1x is a mostly-open, full-custom 22nm SoC for high-assurance applications. It combines a 350MHz VexRiscv CPU with MMU and an I/O processor (BIO) with four 700MHz PicoRV32 cores, plus 4 MiB RRAM and 2 MiB SRAM. It includes TRNG, crypto accelerators, secure mesh, glitch sensors, ECC RAM, protected key slots, and one-way counters; production-qualified with a mask set. A key differentiator is the MMU, enabling open software like Xous. Some subsystems are closed (AXI, USB PHY, analogs), but data paths are inspectable. Open RTL is partial; aims for open silicon-to-software stack.

Vittorio Romeo analyzes C++26 reflection’s compile-time cost. Using GCC 16 in Docker, he benchmarks baseline, <meta>, <ranges>, and <print> dependencies, and several reflection scenarios. -freflection adds no overhead; bottlenecks come from parsing standard library headers: about 149 ms for <meta>, about 440 ms for <ranges>, about 1,082 ms for <print>. Reflecting one struct about 331 ms; +57 ms for 10 types; +22 ms for 20. PCHs or modules dramatically reduce times; modules sometimes trail PCH. Conclusion: reflection enables power but raises per-TU overhead; large projects will rely on PCHs/modules; minimize stdlib dependencies.

Getting Started post explains easing entry into Common Lisp with the ls-dev-image: a batteries-included OCI container bundling Emacs, Slime, QuickLisp, Lisp-Stat, sample data sets and plots. Run: docker run --rm -it --user vscode -w /home/vscode ghcr.io/lisp-stat/ls-dev:latest bash, then launch Emacs and M-x slime. A built-in ls-server starts on port 20202, with a web interface at https://localhost:20202 for plots and data-frames; a refresh script keeps it aligned with upstream Lisp-Stat. Codespaces support; contributions welcome.

IISc researchers led by Kavita Babu studied C. elegans to understand neuromodulation of social behavior. They found that loss of CASY-1 disrupts pigment dispersing factor signaling and unleashes serotonin-driven swarming. The swarm is self-emergent, even from a single worm, shown with CRISPR mutants and optogenetics, plus modeling with Koç University. The work suggests conserved neuromodulatory control of collective behavior and outlines future tests under varying environmental conditions; published in PNAS (2026).

LoGeR (Long-Context Geometric Reconstruction with Hybrid Memory) scales dense 3D reconstruction to minutes-long videos by chunking streams and bridging them with a hybrid memory: Local Memory with Sliding Window Attention (SWA) preserves high-fidelity local geometry, while Global Memory via Test-Time Training (TTT) enforces long-range consistency and prevents scale drift. This results in sub-quadratic complexity and no post-hoc optimization. In tests up to 19,000 frames, LoGeR achieves strong geometric coherence and improved drift, outperforming prior feedforward methods on KITTI, VBR, 7-Scenes, ScanNet, and TUM-Dynamics.

Author notes that macOS Tahoe introduces non-uniform window corner radii: different windows show different radii, e.g., TextEdit vs Calculator, with toolbars making radii more exaggerated. In new Xcode projects, the main window has a smaller radius; adding a toolbar increases it. Other elements like sidebars are affected too. The author criticizes this as a confusing, inconsistent UI change that harms macOS’s reputation for consistency, and mentions a related WebKit bug about scrollbars being cut off by corner radii.

FT homepage headlines focus on the Iran war’s geoeconomic impact—Kharg Island’s oil lifeline and which economies will pay the price—alongside US politics around Trump and Venezuela. In markets, Goldman pitches hedges against corporate loans and talk of emergency oil reserves. In tech, Nvidia-backed AI startup Nscale joins Sheryl Sandberg/ Nick Clegg, Anthropic sues the Pentagon, Microsoft adds Anthropic AI to Copilot, and SoftBank’s OpenAI bet weighs on valuations. The page blends global conflict risk, energy economics, and AI/tech industry news.

FUTILE is a minimalist art project: a useless infinite-scroll site that treats endless scrolling as an experiment. On mobile it measures your scroll distance (in mm) and ranks top scrollers, while the void always wins. The bottom is unreachable, and the piece critiques social-media scrolling. It jokes about thumb tendinitis and lost time, suggests a vague mood boost in an invisible metric, and invites you to scroll for the sake of scrolling.

An overview of the rapid evolution of agentic coding around Claude Code, Claude Cowork, and Codex, detailing new features (agent teams, multi-agent swarms, memory, scheduling, web hooks), performance upgrades (Claude Fast), and the economics of token usage. The piece catalogs hackathon results, real-world deployments, and strong user enthusiasm, alongside cautions about safety, privacy, and malware risks (OpenClaw), as well as warnings about dangerous commands and the need for backups. It also discusses broader implications for software development labor, governance, and the shift toward AI‑assisted coding at scale.

Christopher Drum surveys Lotus 1-2-3’s rise on PC-DOS, arguing it rewrote what a spreadsheet could be and toppled VisiCalc by leveraging 80-column text, more RAM, and an integrated suite (spreadsheet, graphing, database). He recounts Release 2.x and 3.4, explains the key ideas—A1 references with $, a slash-based interface, built-in graphing, dBase translation, and robust macros and add-ins—that made it a business engine. The piece also chronicles HAL, a natural-language wrapper, and the gritty realities of DOS-era usability, plus emulation efforts (DOSBox-X/86Box) and Lotus’s legacy in modern spreadsheets.

Microsoft broke the core value of Windows for everyday users by diverting resources to AI and cloud at the expense of a stable, affordable OS. The piece cites a series of missteps—from the 'Recall' privacy risk and TPM 2.0 gatekeeping to forced Copilot integrations and a disruptive Start menu—plus patch instability and the July 2024 CrowdStrike outage, as signs of neglect. With Windows 10 still in use after end of support and Windows 11 adoption lagging, people are sticking with older, riskier software, creating a trust deficit and signaling a shift toward Azure/AI.
