The Sylvester–Gallai Theorem says any finite noncollinear set of points in the plane has a line through exactly two of them. Kelly’s proof selects the closest point–line pair (P, l). If l passed through more than two points, two would lie on the same side of P′, and constructing a line through P and a point plus a perpendicular from the other would create a shorter distance than the minimum, a contradiction. Therefore l contains exactly two points.

A Zenodo data-and-code archive for the preprint analyzes sample-based quantum diagonalization (SQD/QSCI) on iron–sulfur clusters to test convergence to the target spin. Using a rotation-invariant spin audit (determinant-space ⟨S²⟩, invariant S²-Gram spectra, higher moments), the authors find no audited run reaches the named singlet at a competitive energy; at the largest dimension, the lowest root is ~170 mHa below the published energy but ⟨S²⟩ ≈ 1.37, far from singlet, with hardware samples offering no energy advantage. They urge including measured spin moments as benchmarks. The archive provides full data, code, and reproducibility materials (START_HERE.md, SHA hashes).

NSF's Daniel K. Inouye Solar Telescope (DKIST) team reports the first high-resolution observation of Kelvin-Helmholtz instability (KHI) on the Sun's photosphere, seen as small vortex-like swirls at magnetic boundaries. Combined with simulations (MURaM) from HAO and MPS, the findings confirm KHI as a driver of magnetic energy diffusion and possibly heating the outer solar atmosphere, contributing to space weather processes. The study, published in Nature, suggests KH vortices constantly twist and mix magnetized plasma, potentially fueling flares and CMEs. Future work will automate detection to quantify energy transport to higher layers.

Researchers developed a bioengineered chewing gum (bean-gum base with FRIL antiviral protein, enhanced with protegrin) that targets microbes linked to head and neck cancer. In ex vivo tests on patient saliva, gum extracts reduced HPV by up to 93% and lowered two cancer-associated bacteria, Porphyromonas gingivalis and Fusobacterium nucleatum, by almost to zero with a single dose, while sparing beneficial oral bacteria. The approach could supplement or prevent infection alongside existing therapies. Study led by Henry Daniell (UPenn); published in Scientific Reports.

Oliver Haslam argues that USB-C cables are indistinguishable by sight despite varying charging and data capabilities. He uses a $15 USB-C tester to measure voltage, current, and real-time power drawn, helping identify which cables can fast-charge a 16-inch MacBook Pro and other devices. He notes the importance of e-marker chips and that cables can lie about specs; a tester alone helps, but you can't tell data-speed from the cable without more advanced meters. He pairs testing with a label maker to categorize cables, hoping cables will come with labels or color codes.

Guajes de Ayala, Guerrero: a 50-person self-defense group formed as cartels pressed into remote communities. Armed with U.S.-made AK-47s and AR-15s, grenades, and drones, they patrol mountains to deter the Nueva Familia Michoacana. Born in 2020 after land seizures, the vigilantes reflect a fractured security landscape where multiple cartels and gangs operate; many residents fled, schools closed, clinics shuttered. The government remains split on vigilantes, and the killing of El Mencho threatens to trigger further violence as power shifts.

A visual primer on quantizing large language models. It explains how quantization reduces memory by lowering bit-width from FP32 to FP16, BF16, or INT8, and contrasts dynamic/static PTQ with QAT. It covers symmetric (absmax) and asymmetric (zero-point) quantization, range clipping, and calibration for weights and activations. It surveys 4-bit quantization methods like GPTQ (GPU) and GGUF (CPU offload), and contrasts PTQ with QAT. It also describes extreme approaches such as BitNet (1-bit and 1.58-bit ternary) that speed up large models.

Pokémon Emerald ported to the RP2350 (Cortex-M33) running natively on RP2350B with 16 MB QSPI flash. No emulator; full game at ~60 fps with HDMI output. The decompilation is recompiled for Cortex-M33; the GBA PPU is software-rendered on core1, delivering a 240x160 framebuffer to 640x480 HDMI. Saves persist to QSPI flash; RAM ~378 KB; game image ~11.7 MB on flash. Playable from boot through overworld, battles, and saves, but audio is incomplete, link cable/RFU absent, RTC/time issues, and some features missing. Build uses Pico SDK and includes port docs.

An in-depth overview of vLLM, a high-throughput LLM inference system. It starts from offline single-GPU basics (paged attention, continuous batching) and builds to online, multi-GPU/multi-node serving with a modular engine (engine core, model executor, KV cache, scheduler) and advanced features (chunked prefill, prefix caching, guided and speculative decoding, disaggregated prefill/decode). It covers scaling to MultiProcExecutor with data-parallel and tensor/pipeline parallelism, distributed serving stacks, and benchmarking/auto-tuning. It also describes architecture details like KV-cache blocks, prefix hashing, and external KV transfer via SharedStorageConnector, plus DP load-balancing and an API server stack.

Nepal becomes the 47th government onboarded to Have I Been Pwned's free government service. Nepal's National Cyber Security Centre will monitor Nepalese government domains against HIBP data, enabling detection of exposed government email accounts and rapid response to breaches. The move strengthens threat monitoring and incident response and places Nepal among a growing list of governments using HIBP to protect public resources from compromised credentials.

State-Oriented Consistency: don’t force one uniform guarantee on all state. An OOM in a clustered MQTT broker showed the flaw: loading every client session on startup under Uniform Consistency. The fix: classify state, ask what happens if nodes disagree, find the required guarantee, and choose the weakest mechanism. Result: a 5-row table mapping state to guarantee to mechanism (Live sessions: single authoritative owner — Coordinator; Offline sessions: deterministic placement; Topic routing: availability — AP routing; Durable message state: durability — shared storage; Membership: eventual consistency — gossip). Ownership is deterministically computed; memory scales with ownership, not fleet size. Implemented in Keel MQTT Gateway.

Using the Daniel K. Inouye Solar Telescope in Hawaii, astronomers released the highest-resolution image yet of the Sun’s visible surface. The image shows dynamic, band-like and vortex-like plasma structures in a magnetically active area near a sunspot, with features ranging from about 20 km to thousands of kilometers. The team links many vortices to Kelvin-Helmholtz instabilities at granule edges, marking the first observational confirmation of such instabilities on the Sun. These minute flows may help explain coronal heating and the transport of magnetic energy across the surface.

AMD has acquired AI chip startup Taalas, which bakes model weights directly into silicon as MSICs. In tests, Taalas's HC1 on TSMC 6nm ran Meta’s Llama 3.1 8B at 16,960 tokens/s—about 48x Nvidia GPUs and 8.5x Cerebras. The HC2 aims for 20B parameters per chip, enabling a trillion-parameter model with ~50 chips. AMD plans to pair Instinct-based Helios racks with Taalas accelerators in a disaggregated setup. The deal is an actual acquisition (terms undisclosed) and is expected to close in Q4.

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.
