Permit Pending is a city simulation game in which players act as an elected mayor rather than an all-powerful planner. Every proposed project, from apartment blocks to bus lanes, must survive zoning hearings, public objections, lawsuits and appeals before it can be built, with an underlying economic simulation and a cast of neighbors who react to decisions.
A developer posted a Show HN project called 'The Duck Pond,' a web-based audio simulation featuring three hens, two drakes and two broods of ducklings. All duck sounds are generated in real time through synthesis rather than played from recordings, with spatial audio simulating a listener's position on the bank.
McKinsey & Company will have some entry-level candidates for business-analyst roles complete a 10-minute conversation with an AI-simulated client as part of its interview process, according to The Wall Street Journal. The simulation is meant to reflect about 80% of scenarios consultants typically face, not to stress-test applicants with extreme behavior, and human interviewers—not the AI—will evaluate performance. The pilot runs this fall in select North American offices and could involve hundreds of undergraduate applicants.
Researchers and former officials gathered at Queen Mary University of London for a war-game exercise simulating how nations, companies and NGOs would respond to solar radiation modification technologies that could cool the planet by reflecting sunlight. Participants, including climate researcher Colleen Golja, played roles ranging from national governments to indigenous groups and tech firms, testing how a race to deploy such technology might unfold. The exercise revealed that reaching consensus on ethical, science-based deployment proved far harder than expected.
Researchers at Queen Mary University of London ran a tabletop exercise last September simulating how nations, NGOs, indigenous groups and companies would respond to emerging solar radiation modification technologies. Participants, including roles for governments and tech firms, struggled to agree on ethical guardrails for deploying methods such as spraying reflective particles into the atmosphere to cool the planet. Climate researcher Colleen Golja, who advised players on the science, said she expected easy agreement on ethical research but instead encountered sharp disagreement.
Cloudflare engineers describe building a deterministic simulation testing (DST) tool for celld, a runtime for running Workers and Durable Objects applications outside Cloudflare's infrastructure using only an S3-compatible object store as an external dependency. The simulator, still in development and not yet public, controls event ordering, timing, and storage responses so that failures involving delayed messages, failed writes, or node restarts can be reliably reproduced and debugged.
A developer has rebuilt an old prototype vehicle simulation as a browser-based JavaScript project, layering a 'Brick', a 'Ship' inspired by the 1986 game Thrust, and a 'Car' on top of a shared 2D rigid-body physics core. The system uses true rigid-body dynamics with torque rather than the simplified point-physics hacks common in older games, paired with an approximate, self-described 'not physically accurate' tyre model for vehicle handling.
A gaming writer continues a critique of city-builder aesthetics, focusing specifically on Cities: Skylines 2's flat, overly clean surfaces where sidewalks, buildings, and grass meet without natural transitions. The author contrasts in-game screenshots with more organic real-world or modded examples, arguing the base game looks lifeless without extensive manual decoration.
A developer built a system where AI language models, including Opus 5.5, produce paintings by writing programs that control a physics-based simulation of oil paint on linen, including bristle brushes, wet paint, drying and layered glazes. No image-generation model is used; most models paint in the style of Caspar David Friedrich based only on written research rather than seeing his actual artwork. Of 75 paintings produced, 46 were created incrementally at a simulated easel, with the model working passage by passage and periodically stepping back to assess progress.
The OpenRadioss project's website has been taken offline, with visitors now redirected to a transition page. That page directs users seeking simulation software, technical resources, or ways to participate in future development to Siemens instead.
Researchers used simulations built from ground-truth clonal lineages to test how partial sampling and varying capture rates affect the ability to reconstruct clonal architecture in the newborn mouse forebrain. They quantified how many recovered multicellular clones are needed to detect all cell types within a lineage and how accurately observed cell-type proportions match the true underlying clone composition.
A maker built an installation combining a FLIP (Fluid Implicit Particle) fluid simulation with an electromechanical flipdot display, unveiled at the EMF2026 event. Unable to afford commercial flipdot displays, which reportedly cost tens of thousands of dollars from specialist manufacturers, the creator sourced or built panels through informal networks after being turned down by companies owning existing displays.
