This guide on the Triangle Game frames the multicolor Ramsey problem: color the edges of a complete graph so no monochromatic triangle occurs. With three colors, the largest safe group is 16 (Greenwood–Gleason; 17 is impossible). The 2026 result shows the safe size grows without bound as colors increase, giving a lower bound: there is a safe table with people-per-color at least c · color_count^(1/3) / log color_count. The construction uses a tower of rooms, palettes, a team rule, and a fixed referee; it surpasses older factorial upper bounds and relates to channel capacity. The guide includes interactive pages

Jane Street posts another puzzle: reverse engineer an ASIC from a final GDS layout. Recover a netlist, deduce the circuit’s function, and extract the secret output value. A warm-up provides a simple binary adder with Verilog, netlist, and GDS; tools like KLayout/Magic and an open-source PDK help. Submissions close Sept 4, 2026; collaboration allowed, no spoilers online until after, and avoid feeding the puzzle files to AI (AI can help write scripts). A future competition may fabricate entries. For more, see Hardcaml and Jane Street hardware jobs. Authors: Anish Singhani, Ben Devlin.

Two UC tech workers describe how 2,100 information technology employees joined UPTE-CWA Local 9119 to win job security and a vision of tech serving people. Using organizing committees, surveys, conversations, and home visits, the union built support among a workforce. In California, a majority of the bargaining unit had to vote yes, and after five strikes (Dec 2024–Nov 2025) the UC won a contract with about 22% raises over three years, up to $300/mo in health-premium savings, and cross-campus layoff protections. They say unions can steer tech toward serving people and public services against AI-driven layoffs and private-profit priorities.

PostgreSQL cannot parallelize count(distinct ...) because distinct requires seeing all values in one place (sort or hash) to deduplicate; partial aggregates cannot merge distinct across workers. As a result, a query like SELECT count(distinct user_id) FROM events is serialized with a top-level Aggregate and an external sort, even on multi-core systems. The recommended rewrite is to push distinct into a GROUP BY: SELECT count(*) FROM (SELECT user_id FROM events GROUP BY user_id) s; this enables parallel hash aggregation. For per-group distinct, similarly group first per group. Use EXPLAIN to verify plan shape.

Can Celik explains why Herdr, a terminal-based runtime for running software agents, evolved into a platform with a TUI and a growing plugin ecosystem. He built a persistent runtime so agents can run across projects and machines, with a bundled UI and multiple clients (Raycast, Stream Deck, iOS). After 25k stars and 340k downloads, Herdr is joining Y Combinator (F26) with plans to hire a small team while keeping the core runtime free under Apache 2.0. The strategy emphasizes open-source, extensibility through extensions, and a lean core to stay lean while enabling broader adoption.

SpaceX's xAI subsidiary operates the Colossus data center near Memphis with dozens of unpermitted gas turbines spewing smog and toxins. A Clean Air Act suit by SELC/NAACP prompted federal involvement, though the DOJ framed it as national security. On July 30, 2026, xAI agreed with Mississippi DEQ to remove the turbines and replace them with a natural-gas plant by July 2027, amid concerns of environmental racism, health harms, and aquifer depletion. Critics say the "move fast" ethos sacrifices accountability and is shielded from scrutiny.

Artificial Analysis provides independent AI benchmarks and leaderboards, centered on the Intelligence Index v4.1.1, evaluating 9 benchmarks (GDPval-AA v2, 𝜏³-Banking, Terminal-Bench v2.1, SciCode, Humanity's Last Exam, GPQA Diamond, CritPt, AA-Omniscience, AA-LCR). It reports speed, cost, tokens, and endpoint accuracy, plus openness and pricing across 595 models from multiple providers. It also hosts specialized indices (Agentic, Coding Agent, Image/Video, Speech, Capability) and ongoing methodology updates and new model evaluations.

Philip Zeyliger argues no-code platforms like Airtable have peaked as LLM-driven tool use reshapes software. He traces a shift from spreadsheets and bespoke IT to cloud VMs, praising Linux-based stacks for portability and lighter lock-in. Exe.dev offers hosted Linux VMs and dev environments to build AI agents, enabling end-to-end, agent-powered apps in production. Key features include preinstalled agents (Shelley), Integrations, secure sharing, easy porting of spreadsheets, scheduling, and automations. Pricing starts at $20/month for 50 VMs (2 CPUs, 8GB RAM) with scalable resources.

ChipTycoon is a theme-park simulation of a semiconductor fab. A cart carries one wafer through twenty stops, with the cargo visibly changing from sand to rough silicon, a crystal, a disc, then chips. The middle ring shows that making a chip is printing many layers—about sixty—repeated across four laps. The ride pace speeds up after reading all stops, and you can pause, skip, restart, or follow the camera. The process shown mirrors real steps: quartz sand, carbon reduction, Siemens purification, Czochralski growth, wafering, polishing, mask making, deposition, photoresist, exposure, develop/etch, ion implantation, copper wiring, probing, dicing, packaging, final sort.

FCC eliminates the 39% cap on TV households a single company can reach, replacing it with a case-by-case approach (vote 2-1). Carr says the cap is outdated; opponents such as Free Press and Sen. Elizabeth Warren call it unlawful and warn it will boost consolidation and erode localism. Nexstar, the nation’s largest broadcaster, benefits and is pursuing a $6.2B Tegna merger that would reach about 60% of households. Critics fear antitrust challenges and reduced viewpoint diversity; the move accelerates media consolidation.

Rafael Epplée outlines building progressively enhanced forms with htmx, using a bookmark-editing UI as example. The article contrasts transient state in server-rendered flows with SPA JS memory, and shows techniques to survive interactions: keeping user input in form values, using query parameters/paths, GET forms, and button formaction values to detect which action ran. The approach starts without JS, then adds htmx features (live search, loading spinners) on top. He notes tradeoffs of page swaps, strives to avoid stale data, and suggests testing with JS off and consults resources on server-rendered + htmx patterns.

Wirecutter investigates Talenti’s decline from a premium gelato icon to an inconsistent product. Nine flavors were sampled; vanilla was subpar—thin, sour, and foamy—and several other flavors fared poorly. The piece traces recipe changes: gums (carob, tara, guar) added over time and shifts in vanilla beans (pods to extract and specks). It also explains packaging woes: ultra-tight lids from blast-freezing and two-material jars, with an interior seal that worsens opening friction. Talenti was bought by Unilever in 2014 and divested in 2025; nostalgia lives on, jars persist.

Zapscape is a KVM/x86 use-after-free vulnerability (CVE-2026-64561) in the shadow MMU recursive zap path that lets a guest escape to the host and gain root privileges, threatening guest–host isolation in multi-tenant x86 clouds. A PoC targets AMD/KVM emulated by QEMU, showing how guest actions can compromise the host and create a /Zapscape file on the host. Affected versions span f95eec9bed76 to 2abd5287f083. The PoC is demonstration code, not weaponized for immediate cloud use; disclosure is public.

GitHub reports an incident affecting Actions (and Pages). Workflow runs are failing or delayed; some Actions API requests error, and migrations with GitHub Enterprise Importer may fail. Engineers have deployed mitigations and are rolling out a further fix. Pages is experiencing degraded performance; overall service degraded with ongoing investigation and recovery efforts.

Metro Council approved using eminent domain to try to buy the property next to the Nashville Zoo for DC Blox’s planned data center, 27-5. The move starts negotiations but faces a long process: zoning appeals, a December moratorium, and potential court battles. An amendment would require Metro to receive and consider an appraisal and wait three weeks before filing condemnation. Supporters cite office-space needs; critics warn of high costs and the "dangerous" use of condemnation. The deal hinges on broader data-center zoning and possible delays.
