A UN report warns of 'water bankruptcy'—irreversible depletion of natural water reservoirs (aquifers, wetlands, glaciers) from unsustainable use and worsening drought. The study, in Water Resources Management, notes that over 40% of irrigation water comes from draining aquifers, and more than 70% of aquifers are in decline; wetlands have shrunk by about 1.5 million sq miles, and glaciers by 30%. About 3 billion people live where water storage is unstable. Pollution and runoff render water unusable. Hot spots: Middle East, South Asia, U.S. Southwest. Calls for halting irreversible loss and sustainable farming; ahead of a UN meeting in Dakar.

Instabridge has acquired Nova Launcher. The product will remain stable, compatible with modern Android, and actively maintained. The company promises responsible stewardship: keep performance and customization core, fix bugs, and listen to the community via Reddit, Play Store, and email; a support channel will be announced. Nova’s identity will stay intact, with changes evaluated for performance and user control. They may introduce paid tiers or ads for the free version, but Nova Prime remains ad-free and existing Prime purchases will be honored. Nova Prime price is now $3.99; open-sourcing and privacy practices will be considered; long-term, step-by-step plan.

Amplify profiles Hightouch’s production agent harness, designed for long-running, open-ended marketing tasks. The team separates planning from execution, letting the model generate and update a plan that guides steps. They use dynamic plan updates via special tool calls to revise the plan as new data appears. To manage context, they buffer large results to files and use dynamic subagents—offloading messy work to isolated, cheaper models and then summarizing. They also fan out to many small models instead of relying on embeddings. The result is a scalable, in-production agent capable of deep reasoning and adaptive planning.

wxpath is a declarative web crawler that expresses traversal with XPath. It runs asynchronously (aiohttp) and supports url(...) and ///url(...) for deep, breadth-first crawling, streaming results as they’re discovered. It can be used from Python or via a CLI, outputs JSON-friendly maps, and respects robots.txt by default. Optional persistence backends (sqlite or redis) and pluggable hooks are available. The project is early in development and APIs may change.

Hoover Dam’s Monument Plaza hides a 26,000-year celestial map in its terrazzo floor, encoding the dam’s completion date via Earth's axial precession (25,772 years). Sculptor Oskar Hansen arranged a circle around the central flagpole to map Polaris’ angle and visible planets, enabling a date precise to a day. Alexander Rose retraces the project, revealing scarce documentation, obtaining building plans, and explaining how precession times the opening. The design notes Thuban as ancient North Star and Vega as future North Star, linking the plaza to Long Now’s 10,000-year clock vision; the floor may endure for millennia.

The text is a Google/YouTube CAPTCHA warning noting unusual traffic from the reader’s network has triggered a block. To proceed, the user must solve a CAPTCHA; blocks may occur when automated scripts, malware, or fast requests are detected. If sharing a network, an administrator should be consulted since another device could be responsible. The message includes the user’s IP, timestamp, and the video URL.

Meta’s lawyers are accused of abandoning their ethical duties like Big Tobacco: destroying evidence, burying research on harm to children and teen mental health, and shielding findings behind attorney-client privilege. Whistleblowers testified to a “funnel of manipulation” in safety research, including VR child exploitation concerns; a 2025 DC judge invoked the crime-fraud exception to pierce privilege. Rooted in John Adams’s threefold duty to client, court, and country, the piece argues for accountability through bar investigations, possible disbarment, and privilege reform. Meta isn’t unique; similar misconduct has surfaced at Snap, Google, and OpenAI. Upholding truth is essential to legal legitimacy.

SquishyGo is a free browser Go game with 5x5–9x9 boards. Play AI (Lv1/Lv2) or humans, with pass, resign, undo, and 'do over' tickets earned by watching ads. It uses simplified Jungo rules: stones are captured by surrounding, and you cannot repeat a previous position (ko). The game ends after both players pass; the winner has more stones. Stones have cute faces; you can add to your home screen on Safari. Updated version may require a refresh.

Anthropic's Claude Code and Claude Cowork spotlight AI agents and a unified UI, fueling fears that software stocks could suffer as AI handles information synthesis, GUI, and workflows. Historically, software shares underperform during tech selloffs; some call Claude Code the ChatGPT moment repeated, potentially compressing software valuations as demand shifts to AI-enabled platforms. Bulls see this as a long-term opportunity to own AI winners amid rising server demand, while tariff headlines and rotations keep tech volatility high.

Creative PostgreSQL optimizations beyond standard indexing. Uses constraint_exclusion to skip full table scans when constraints guarantee no results, beneficial for ad-hoc BI queries. Demonstrates lowering cardinality by indexing the date portion of timestamps with a function-based index, producing much smaller indexes and faster queries; to ensure use, introduces virtual generated columns (Postgres 18) though indexes on them aren’t yet supported. Shows enforcing uniqueness with a Hash-based approach via an exclusion constraint, yielding a much smaller index, but with FK and ON CONFLICT limitations; suggests MERGE as workaround.

UNIX Pipe Card Game teaches kids to combine Unix commands via pipes (cat, grep, tail, head, wc, sort, uniq). The youngest player picks a task (e.g., print the second line, most common line), shuffles and draws cards, and players build a pipeline to complete the task; first to finish earns a point. Includes a parent deck and an Expansion: Process Substitution. PDFs, code and authors are listed; CC BY 4.0. If no Unix, use jslinux in the browser. Related games cover Python, pointers, memory, and more.

This post estimates Nvidia’s chance of closing below $100 at any time in 2026. It argues that a simple unbiased random walk fails because volatility scales with sqrt(t) and drift matters over longer horizons. It uses a binomial option-pricing model with implied daily volatility ≈3.1% from a 340‑day $100 call, to simulate crossing the $100 barrier. A naïve calculation yields ~24%, but the author notes p̃ is not a true probability. Calibrating option-implied risk-neutral to real-world via a Bank of England beta-curve reduces the estimate to about 14%, with the author ultimately settling on ~10%.
