A user reports a systemic issue affecting Steam Networking–based peer‑to‑peer (P2P) games in Israel and possibly other Middle‑East regions since March 13. In titles such as *Street Fighter 6*, Israeli players experience round‑trip latencies of ~120 ms when connected PC‑to‑PC, compared with 60–80 ms to European peers and 5–10 ms when cross‑playing with PS5. The problem is isolated to Steam’s P2P networking; games that use alternative networking stacks (e.g., *Tekken 8*) do not show the latency increase. Multiple Israeli users across various ISPs have confirmed the issue, and ISP‑level diagnostics and port‑forwarding attempts have revealed no local network faults. Anecdotal reports suggest similar symptoms in Egypt, indicating a potential regional scope. No resolution or guidance from game or Steam support has been provided.

ntsc‑rs is a software tool that applies a precise VHS‑style video effect. The available screenshots show its user interface, a direct side‑by‑side visual comparison with Red Giant Universe’s VHS effect, and a sample render completed in 15 seconds, demonstrating its performance. The tool can also be loaded as a plugin within nonlinear editing (NLE) applications, allowing users to integrate the effect into standard video‑editing workflows. Overall, ntsc‑rs emphasizes accurate emulation of analog VHS characteristics while offering rapid rendering and compatibility with existing editing pipelines.

The site hosts a public domain image archive containing 11,082 out‑of‑copyright works. All images are free to browse, download, and reuse, with the collection continuously updated each week. The archive is organized under an “Images and Visual Content” section, exemplified by an entry labeled “Image 1” with alt text referencing “The Public Domain Review.”

Symbolica 2.0 expands the Python‑Rust symbolic computation framework with programmable symbols and extensive API refinements. Users can now attach custom hooks for simplification, differentiation, series expansion, and evaluation, enabling symbols such as γ to regularize poles via user‑defined series callbacks. The Rust API is streamlined through a prelude, builder‑style constructions, and reduced import paths; functions, settings, and evaluator configuration can be fluently combined. Evaluators rewrite expression trees into optimized instruction programs, support JIT compilation (via symjit), and now include a double‑float domain offering ~106‑bit precision at three‑fold speed over arbitrary‑precision arithmetic. Custom evaluation hooks can be registered for multiple numeric types (f64, Complex, Float, etc.) using type‑erased storage and later specialized without runtime overhead. New built‑in special functions (gamma, polylog, Bessel, zeta, etc.) provide immediate normalization and can be used inside optimized evaluators, with constants folded to numeric literals during code export. Performance improvements—faster pattern matching, byte‑slice term sorting, enhanced Horner schemes, and a modular polynomial GCD algorithm—yield 2‑10 000× speedups on real workloads. Future work includes optional GMP‑free arbitrary‑precision backends for WASM compatibility.

The article traces the rise of “liminality” as a dominant visual aesthetic, linking contemporary internet culture to earlier artistic precedents. It cites the abandoned Century III Mall in Pennsylvania as a prime example of a “ghost mall” captured in a 2025 Facebook post, illustrating the aesthetic’s focus on empty, transitional spaces. The phenomenon is rooted in the 2019 “Backrooms” creepypasta, which imagined infinite, unpopulated rooms and spurred a community that now shares thousands of similar images across Facebook, Reddit, and Instagram—often barring AI‑generated content. The piece highlights key visual motifs (e.g., carpeted hallways, dim lighting) and compares them to works by Surrealists such as de Chirico and Magritte, as well as American painters Edward Hopper, Grant Wood, and Andrew Wyeth, noting shared themes of isolation and “in‑between” settings. Scholars cited argue that liminality reflects contemporary anxieties of anonymity, digital homogenization, and post‑industrial alienation, intensified by COVID‑19 shutdowns but persisting beyond that period.

Chemists have experimentally observed a boron buckminsterfullerene (B₈₀), confirming the existence of an 80‑atom cage first predicted in 2007. The clusters were generated by laser vaporization of a boron target in a helium/argon carrier gas, allowing rapid cooling that stabilized B₈₀ into a single geometry. Photoelectron spectroscopy produced three sharp peaks that match simulated spectra for the buckyball structure, while alternative B₈₀ isomers did not fit the data. This result challenges prior density functional theory (DFT) calculations, which had ranked the buckyball geometry as less stable than other B₈₀ forms; the authors argue that DFT inadequately describes this system. B₈₀ is valence‑isoelectronic with C₆₀, sharing 240 valence electrons and similar bonding, and may exhibit higher electron affinity, suggesting potential applications as a semiconductor, hydrogen‑storage material, or doped superconductor—pending bulk synthesis. The team plans reactivity studies with water and oxygen and to explore larger boron clusters to assess the persistence of the cage motif.

oproxy is an open‑source MITM proxy that runs locally (or in Docker) and supports HTTP, HTTPS, and SOCKS5 traffic. It captures requests and responses, displaying headers, bodies, status, timing, tags, notes, and inspector data for JWT, GraphQL, gRPC, and WebSocket frames. Captured sessions can be replayed, exported as HAR, cURL, Fetch, or Python snippets, and imported back. Traffic can be modified via rule sets, map‑remote/local, access controls, throttling, breakpoints, mock responses, DNS overrides, capture filters, Lua scripts, or upstream proxy chaining. An authenticated Assistant interface allows OpenAI‑compatible chat models to inspect state and apply confirmed changes. The service runs as a forward HTTP proxy (default port 8080), optionally provides SOCKS5 and additional TLS listeners, and serves a management UI and API on the same endpoint. Persistent volumes store CA certificates and session data. Build requirements are Rust ≥ 1.85, Node.js ≥ 22, and Yarn via Corepack; Docker images are also provided. The MIT‑licensed tool is intended for developers testing browsers, CLIs, mobile apps, APIs, and automated test suites.
