France will reduce reliance on extra-EU proprietary tech to boost digital sovereignty by replacing Windows with Linux. DINUM ordered ministries to map dependencies and plan exits from non-EU tech by fall, with rollout across ministries, operators, and industrial partners. While open-source EU options like openSUSE exist, the move aims to curb dependence on US tools and regain control of data, infrastructure, and pricing.

BlueHammer is a Windows privilege-escalation chain exploiting Defender during a definition update. It weaves five components—Defender, Volume Shadow Copy Service, Cloud Files API, opportunistic locks, and Defender RPC—to read SAM/SYSTEM/SECURITY from a temporary shadow copy, decrypt NTLM hashes, reset a local admin password, log in as SYSTEM, copy the token, create a service, and spawn a SYSTEM shell, then restore the hashes. It requires a pending Defender signature update; no CVE. PoC on GitHub by Chaotic Eclipse. Mitigations: monitor VSS, Cloud Files roots, rapid password changes, new services, and tighten permissions.

WeakC4 presents a search-free, low-knowledge weak solution to 7x6 Connect Four. It relies on a formal 'Steady State Diagram' language to describe winning continuations for a subset of positions and an opening-tree of leaves containing those tricks. Red-to-move moves are uniquely determined by a fixed priority list; the solution uses no runtime search (O(wh) move) and fits about 150 KB, with under 10,000 nodes (two-thirds leaves). It uses a genetic algorithm to pick branches, brute-force verify, and visualizes the game; an Anki deck aids memorization. It contrasts with strong solutions, illustrating structure over brute force.

Argues the common calendar misaligns seasons with daylight; first days of seasons are misleading (e.g., summer starts on the solstice though days decline). Proposes a new calendar that centers each season on the solstice/equinox, shifting starts to May 7 (summer), Aug 9 (fall), Nov 6 (winter), Feb 21 (spring). Adds that this North American-centric view overlooks other traditions that place the solstice in midsummer; the idea aims to align seasons with daylight patterns.

AP News profiles Aadam Jacobs, who recorded more than 10,000 concerts—from Nirvana’s 1989 Chicago show to Björk and dozens of indie bands—over four decades using gradually improving gear. Now volunteers in the U.S., U.K., and Germany are cataloging, digitizing, and uploading the tapes to the Internet Archive, making rare live performances available for streaming and download. The project relies on careful metadata work and occasional artist cooperation (The Replacements, etc.) and faces copyright questions, but with no profit involved lawsuits seem unlikely. Jacobs, now in poor health, remains a devoted music fan.

Max van IJsselmuiden argues that procrastinating on large tasks can feel productive when you pursue newer, enjoyable work. Through Casey Neistat’s four-quadrant matrix, he distinguishes productive procrastination from true progress. The brain’s limbic system fights negative emotions tied to hard tasks, while the prefrontal cortex plans long-term goals. Novelty drives reward through dopamine; guilt and moral licensing complicate follow‑through, and the Zeigarnik effect sustains unfinished tasks. Remedies include affect labeling, self-forgiveness, and making older tasks feel new, plus habit cues to start work.

The piece celebrates vintage government report covers as art, highlighting how mid-20th-century transportation reports paired data with striking visuals. Northwestern University Transportation Library curator Rachel Cole shows covers like Transporting Watermelons in Bulk and Bins by Truck and A Report of Highway Death in Missouri, noting they used design to engage readers and tell stories about mobility and safety. The article discusses designers' roles, shifts to PDFs in the 2010s, budget pressures, and the rise of clip art and AI, arguing that modern, plain covers lose the memorable, human-centered impact of earlier artwork.

The Allegro team compared detekt, diktat, and ktlint for Kotlin static analysis to enforce method/field ordering. None enforce ordering out of the box. Ktlint remains fastest and formatting-focused with minimal config. Diktat is thorough but overly strict, noisy, and hard to tailor. Detekt offers many rules and a custom rule API, and they prototyped a visibility-order rule, but it adds maintenance cost and lacks Java 25 support. Conclusion: stick with ktlint for formatting; use detekt for targeted quality issues if needed, but not as a broad replacement.

FAA launches an ad campaign urging gamers to apply for air-traffic-control jobs to address a long-running shortage. The effort uses Xbox imagery and highlights a $155,000 salary after three years, arguing that tech-skilled gamers fit the role. Transportation Secretary Sean P. Duffy says recruitment must adapt to a new generation, echoing a 2021 'level up' push. The drive follows high-profile aviation incidents. The FAA says staffing is at a six-year high but warned of about 3,000 vacancies and many retirements by 2028; it remains critically needed.

Colin Percival reflects on 20 years with AWS and FreeBSD on EC2, from 2006 when S3 sparked his interest to advance FreeBSD on EC2 (and NetBSD), through early security concerns about unsigned responses, signature schemes, and process improvements (Signature Version 2, IMDSv2). He details iterative work—Xen kernel limits, public beta of Tarsnap using SimpleDB, and the t1.micro era—plus leadership as FreeBSD Release Engineer and later sponsorship to sustain FreeBSD/EC2. He notes collaboration with AWS teams, the IAM evolution, AWS Heroes, and ongoing security debates that shaped his two decades with AWS.

STARFLING is a mobile game where you tap to release a sling between stars. The screen shows your score (0) and best (0), with options to resume, restart, or play again; you can watch ads to continue or revive after game over, and there are prompts to share on iOS/Android.

quien is a Go-based interactive TUI tool for enhanced domain/IP lookups, including WHOIS, RDAP, DNS, mail, SSL/TLS, HTTP headers, and tech-stack detection. It uses RDAP-first lookups with WHOIS fallback, automatic WHOIS server discovery via IANA, and IP lookups with reverse DNS and abuse contacts. JSON subcommands enable scripting. Features include exponential-backoff retries and tech-stack detection (e.g., WordPress plugins, JS/CSS frameworks). Install via brew tap retlehs/tap/quien or go install github.com/retlehs/quien@latest. Usage covers domain, IP, and JSON outputs; aliasing can replace the system whois.

Zettelkasten is a network of atomic ideas, not a folder or tag system. In Obsidian, use minimal structure (00 Inbox, 10 Literature Notes, 20 Permanent Notes, 30 Templates). Capture fleeting notes quickly in Inbox; weekly, convert to literature notes; distill into 1–3 permanent notes; link notes as you go; create Maps of Content only as needed. AI, especially Desktop Commander, can maintain large vaults by reading local Markdown files, identifying orphaned notes, stale MOCs, and suggesting/linking connections. A weekly ~15-minute routine plus prompts keeps it scalable.

An author describes Bevy game-development guides that started for friends and grew into a comprehensive Bevy resource. Written by a Ruby/web developer, the site is built with Staticky and links to Bevy Starter, Awesome Bevy, and Soldev for Rust/Solana. The guides cover Bevy 0.18 topics (apps, components, physics, UI, patterns, etc.) and tutorials like Pong. The collection includes extensive Bevy tutorials, commands, queries, plugins, and system patterns. Contact: [email protected].

Split locks are atomics that cross cache lines, forcing contention and often becoming 'bus locks' on modern CPUs. Across tested CPUs (Intel Arrow Lake/Alder Lake, Skylake; AMD Ryzen Zen 2/Zen 5, Piledriver), split locks wreck performance, especially for L1 misses, and can devastate L2/L3 and DRAM throughput; latency can rise to microseconds in some cases. Some architectures (e.g., Piledriver) handle them comparatively better; others (Zen 5, Arrow Lake’s modern cores) suffer heavy penalties. Linux mitigations trap and delay splits to curb noisy neighbors, but the author argues consumer systems should avoid split locks and calls for precise, data-driven improvements.
