New York thoracic surgeon: "For many patients 9/11 is not over"

Thoracic surgeon Raja Flores writes about the ongoing health toll from Sept. 11 for Ground Zero responders and others exposed to the dust. Years after the attacks, thousands face cancer, asthma, digestive and other illnesses, with funerals continuing. While individual causation can’t be proven, science shows elevated risk among the exposed. About 140,000+ are enrolled in the World Trade Center Health Program, and more than 8,000 have died. For many, Sept. 11 is not over after 25 years.

I've operated petabyte-scale ClickHouse clusters for 5 years

Tinybird offers a managed ClickHouse-based data platform with DX Ingest, sub-second SQL APIs, Kafka Connector, AI-focused DevEx, zero-downtime migrations, and enterprise-grade workspace and cluster management. The included blog recounts five years running petabyte-scale ClickHouse clusters: architecture uses replicas and shards with cloud storage and zero-copy replication; upgrades and ingestion are the main pain points; effective ingestion requires balanced batch inserts, partitioning, and backpressure; storage choices (hot SSDs for cache and hot/cold with S3) influence costs; success hinges on testing across versions, monitoring, and trained operators. Tinybird aims to simplify analytics without hosting ClickHouse.

Diesel prices in U.S. top $6 a gallon for first time

Diesel prices in the U.S. topped $6 a gallon for the first time, averaging $6.05 nationally and $7.98 in California, with regular gas at about $4.29. The surge reflects tighter global supply from the Iran conflict, reduced refining capacity in the Middle East and Russia, and Ukraine strikes, with Brent near $108. The rise is already hitting wholesale costs and could soon be passed to consumers, affecting groceries, furniture, and vehicle charges. Analysts say relief could be months away and uneven.

Re-Engineering YouTube for the Living Room: Bringing "Chrobalt" to RDK

Collabora, with Google’s YouTube Cobalt and Partner Engineering, delivered the first RDK-based Chrobalt reference platform for third-party living-room devices on Amlogic. Chrobalt merges Cobalt with Chromium via Starboard for a modern web engine on low-power TVs and STBs. Collabora modernized Starboard/toolchains, integrated Chromium tests with NPLB, and enabled YTS certification for 4K/UHD, DRM, and input latency. They integrated Chrobalt into RDK7, upstreamed fixes to Cobalt/Starboard, and built a Rust DAB adapter for automated testing. Shown at BlinkOn and YouTube Device Partner Summit; enables OEMs like Samsung/LG to deploy YouTube on RDK.

Show HN: ClaudeStatsBar: your session is 486k deep and nothing told you

ClaudeStatsBar is a Python utility for Claude Code that shows the current session’s context size, token costs per turn, and remaining headroom within 5h and 7d windows. It displays a live status line (e.g., 486k context, 49k/turn, ~162t left) and warns when limits approach. The API is stateless; context grows as turns re-send prior messages. The repo provides installation via install.sh, config in ~/.claude/settings.json, Windows and POSIX instructions, and an MIT license. It emphasizes that shorter prompts aren’t the lever; reduce turns or clear/compact between tasks.

Houthis 'take control' of key island in global shipping route

Houthis claim Mokha and Perim Island capture, giving control over a key Red Sea chokepoint (Bab al-Mandab) and raising shipping risks. They say navigation is safe for all vessels except Saudi ships, which they blockade. The move threatens Saudi oil exports and could push oil prices higher, with displacement in Yemen around 46,000. The US says it remains in regular contact with allies to defend freedom of navigation.

If coding is solved, what now?: Measuring the sloppiness of code

LLMs generate code that is often correct but sloppy—extra abstractions, duplicates, and poor structure that grow with LOC. Evaluating sloppiness is hard: AI judges are unreliable and human judges aren’t scalable. The article highlights SlopCodeBench metrics: Verbosity (flagged/clone lines relative to LOC) and Erosion (mass in complex functions CC>10 relative to total mass). In benchmarks, repos show Verbosity ≈0.15 and Erosion ≈0.31, while agent code is ≈0.33 and ≈0.68, roughly twice as sloppy. Iterative, context-clearing testing worsens outcomes. The author calls for robust, human-informed evals and future work (coupling, churn, cohesion).

Moonshot serves Claude instead of Kimi and collects exchanges for model training

Anthropic’s threat report shows Claude misused for cyberattacks, influence ops, surveillance, biology, and weapons, and how defenses disrupted these efforts. A Meta veteran warns the gap between lone actors and nation-states has closed, as agentic tooling enables recon, exploitation and exfil at APT-scale. Attacks chase stolen API keys and session tokens; 'living off the land' lets attackers run workloads under victims’ IDs. AI fuels scalable recon and influence operations and widens surveillance capabilities. The piece urges sharing threat indicators with platforms and society, noting the need for safeguards and cautioning about foreign actors routing prompts to US firms.

Experiment – Projectional Viewer

Tarvydas tests a projectional viewer that hides implementation details to reveal cleaner structure. Beginning with a Rebol phone-number grammar, he strips copy clauses and the trailing action, leaving parse "(416)555-1234" [ "(" 3 digits ")" 3 digits "-" 4 digits ]. An Emacs Lisp tool, pellide-view.el, pipes the source through a pipeline (OhmJS parser + RWR rewrite rules) to yield the elided grammar and display it in the editor; toggling back shows the source. Observations: elided grammar reads better and toggling is fast. Next: test PEGs (Lua, Janet), detect elidable regions, and explore composing many small DSLs via transmogrification.

Remember Hong Kong

Hong Kong’s democracy fight—led by Jimmy Lai and Joshua Wong—faces a harsh rollback as the CCP’s National Security Law silences dissent. Wong, once Time’s “Face of Protest” and now facing a potentially life sentence after pleading guilty to urging sanctions, exemplifies a generation’s risk. Lai remains imprisoned; Nathan Law sought asylum in Britain. The piece argues that despite global missteps (e.g., Trump’s torn stance) and Beijing’s victory for now, repression cannot erase the longing for freedom; the arc of justice, though long, bends toward liberty.

Instagram's head says engagement falls by half without the algorithm

Instagram head Adam Mosseri warned that turning off the platform’s recommendation algorithm can cut engagement by up to 50% and lower satisfaction, arguing this happens when a chronological feed floods with brands and publishers. Australia is considering a Digital Duty of Care bill that would require a prompt to turn ranking off, rather than a hidden option. The debate centers on who should initiate feed customization. Europe’s Digital Services Act already pushes a non-profiling feed; adoption is modest, raising questions about wellbeing metrics.

RTK reports token savings, but our cost benchmarks disagree

RTK promises large token savings by compressing terminal output. Benchmarks on Claude Code (Fable 5.0) and OpenCode (DeepSeek V4 Pro) show mixed results: initial cost reductions for Fable but increases for DeepSeek; when counting failures and averaging per task, savings largely disappear. DeepSeek costs rose up to ~17–18%; one task dominated gains for Fable. RTK gain measures removed output rather than money saved, and extra turns often negate benefits. Conclusion: RTK does not reliably lower AI-coding costs; it's a niche optimization, not a general saver.

The Waymo effect: how AI is quietly making research less collaborative

The Waymo effect argues that frictionless AI—especially large language models— is quietly making research less collaborative. By replacing human friction with prompts and instant outputs, it fosters decollaboration, prioritizing speed and individual productivity over the serendipitous conversations that fuel science. Funding cuts, velocity-centric evaluation, and credit-free AI outputs also erode co-authorship and idea diversity. Writing is thinking; outsourcing it dulls deep understanding. The remedy: fund friction (workshops, visits, co-location), evaluate contributions rather than speed, and design pilot-in-command workflows with humans steering and diverse models in the loop.
