Ploum outlines an uncompromising AI policy: no interaction with AI or its outputs as sources; prefer human-written content and critical thinking. He distrusts generated images and code, warning that reliance on AI makes projects hard to maintain. He champions open source for maintainability and accountability. In education, students must submit work wholly produced by themselves. He views AI as addictive and harmful to learning, culture, and the economy, and urges avoiding AI discussions in class to keep human agency at the center.

Procedural Graph stores procedural knowledge as (procedure, relation, procedure) triplets to guide LLM agents with step-level, queryable hints rather than an unbounded history. A guidance model translates the surrounding subgraph into situational hints that bias the next action without dictating it. The graph self-evolves: an LLM refiner contrasts failed vs successful trajectories, edits topology and attributes, and commits only edits that improve held-out validation, discarding the rest. Starting from a minimal skeleton, it matches or surpasses hand-designed graphs and can repair flawed priors. It outperforms memory baselines across datasets and LLMs, with added gains from self-evolution.

Overview of Penrose P3 tilings and a concrete subdivision algorithm. The article explains tilings, prototiles, periodic vs aperiodic patterns, and how P3 uses two rhombi derived from four Robinson triangles. It presents a four-rule subdivision system to recursively refine triangles, and shows how to encode these rules as term-rewriting rules and implement them in code (generateP3). It discusses a cyclotomic-based, integer-coordinate representation using the golden ratio to represent vertices, enabling exact comparisons and avoiding floating-point error. It notes the acute/obtuse pair structure and pentagonal symmetry, with references for further reading.

Seven months after disputing a missing cheese packet via an AI agent, the author demonstrates a high-ROI system for winning consumer-claims with AI. Starting with a $10 coupon seed, he built a process where an AI agent researches contracts, regulators, and filing options, crafts strategy, and manages negotiations across multiple levers (warranty, regulator, arbitration, publicity). The tally exceeds $12,000 recovered across IRS penalties, warranties, insurance disputes, and more. The approach reduces cognitive load, reframes customer service as an ongoing campaign, and signals a shift where AI-enabled consumers disrupt the traditional funnel.

Rahul Ravikumar outlines a method to create a true “Magic Move” for code snippets in presentations, addressing Keynote’s poor code animations. He analyzes diff algorithms and argues visual continuity matters more than minimal edits, favoring Heckel’s O(n) diff over Myers for code morphing. Code is tokenized via TextMate grammars (language-agnostic) into tokens with content, primary scope, depth, and position. Using anchors (unique tokens) and forward/backward passes, he computes diffs to morph snippets smoothly, batching deletions and insertions. The Warp project implements this; Bento later added code-morphing.

Incremental ClickHouse optimizations cut a heavy multi-tenant query from tens of seconds to sub-second latency. Key changes: partitioning from monthly to client_id % 36 for better parallelism; moving event_type earlier in ORDER BY; removing an expensive join by precomputing fields at the application layer; reading fewer columns; replacing nested views with flat, cached dbt templates to cut compilation; tuning merges (raise max_bytes_to_merge_at_max_space_in_pool, set min_age_to_force_merge_seconds) to improve deduping; adding period_ends_at to ORDER BY to enable granule filtering and read fewer rows. Result: ~400ms for the biggest client, ~200x faster, with CPU/memory gains.

Autonomous vehicles appear to reduce crashes and injuries versus human drivers, though data are limited. ADAS, including automatic emergency braking (AEB), cuts pedestrian crashes ~27% and rear-end crashes ~50% with injuries down ~56%; bundled features lower property claims up to ~39%. Waymo reports 20 million robotaxi rides over 220 million miles with 92% fewer fatal or serious crashes and major drops in pedestrian injuries, airbag-related crashes, and intersection injuries. Data quality varies; IIHS urges federal standardization. If such gains hold, preventing roughly 580,000 deaths worldwide annually could be possible.

James Cherti explains that Emacs Consult async searches (consult-fd, consult-find, consult-grep, consult-ripgrep) use debounce, throttle, and refresh-delay to time searches and UI updates. Defaults are conservative, trading speed for CPU and battery life. For faster feedback, set: consult-async-input-debounce to 0.05, consult-async-input-throttle to 0.1, consult-async-refresh-delay to 0.05. Debounce waits for typing to stop; throttle caps start rate; refresh-delay tightens UI updates. The changes speed the feedback loop but not the underlying tools.

The UN endorsed a resolution to promote maps that accurately reflect continental sizes, dethroning the Mercator projection. With 164 countries in favor and one opposed, the move highlights Mercator’s 500-year bias that inflates the Global North. Alternatives include Gall-Peters (equal-area, distorted shapes) and Equal Earth (equal-area with curved lines, better overall accuracy). Equal Earth, created in 2018 after Boston Public Schools adopted Gall-Peters, aims to preserve area accuracy while reducing shape distortion. The UN calls correcting distortions an act of cognitive justice and memorial reparation, noting maps reflect choices about power.

Visa and Mastercard are card networks, not issuers, banks, or payment processors. They don’t issue cards, onboard merchants, or print POS hardware. Their job is to connect cardholders/issuers with merchants/acquirers, creating a two‑sided market. Four core roles: run the telecom network to route authorization messages; coordinate the banking network to settle funds (including international), using net settlement; set incentives via interchange and network fees; and enforce rules and handle disputes (often through arbitration). This structure explains why issuers reward spending and merchants accept card payments.

Reasoning prefills on a few open models, v1.1, reruns an experiment inserting the first 1% of GPT-5.5 Pro’s reasoning into target models’ reasoning channels across 45 tasks (STEM, non-STEM, puzzles). Comparing unprefilled vs prefixed outputs, they measure unigram source recall in the first 100 tokens. Results show increases for several models; Qwen3.8 A95B rises from 33.9% to 54.5% recall (+20.6 pp), with STEM tasks up to +27.6 pp. Kimi K3 also shows gains. Authors suggest Qwen may have learned from GPT-5.5 Pro (or a related model) rather than Opus.

Bomb sense is the player's ability to deploy limited bombs at the right moment in shmups to clear bullets, gain invulnerability, and survive tight patterns. The economy of bombs makes mis-timing costly, while skillful use creates space for strategy and dramatic turns. Bombs forgive mistakes, turning even punishing games into opportunities and often more accessible than raw health. The author loves bombs, sees them as a unique, essential mechanic, and argues that teaching bomb sense is an accessibility/design challenge: not more options, but making the learning process—through tutorials and imaginative design—more approachable, since genre literacy and practice are key.
