Hetzner’s Cloud network stack is Open vSwitch-based, built and operated in-house on VM hosts. Core ideas: keep the moving parts on hosts, provide Firewalls, Private Networks, DHCP, and metadata locally; private networks use VXLAN with unique VNIs; a custom Flusskrebs controller configures OVS flows and handles DHCP centrally. History: from 2011 vServers with NICs and bridges, 2015 Ceph with 1:1 NAT, 2018 direct IPv4 routing, 2019 OVS, 2020‑21 migration to OVS for public network and netfilter firewalls. Current focus: scalability, resilience, IPv6 for private networks; two 10Gb/s uplinks with LACP and BGP.

US DHS proposed rule would require U.S. colleges to pay up to $100,000 for each international student's post-graduate work through OPT, effectively pricing many out of the program. The plan would cut OPT enrollment by up to 44% and cost universities $8.4-16.5B annually, potentially halving bachelor-enrollments and nearly eliminating master's entrants in OPT. International STEM PhD grads rely on OPT (about 70% in 2022). Critics warn it would devastate the US STEM talent pipeline, reduce college revenue, and drive students abroad; supporters say it would curb fraud. Impacts could shrink the broader STEM workforce by 6-11% over a decade.

Fleeting is a web tool that plays long, realistic but fake meeting audio to make others think you're busy. Users select a meeting, set title, date, start time, duration (15–90 minutes), and repetition; can add a join link to calendars (ICS, Google Calendar, Outlook) and mark events private. The audio loops ~12 minutes from random starting points; endings are simulated as participants say goodbye. If 'Back-to-back meetings' is enabled, it jumps to another suitable meeting after a few seconds; otherwise it loops. Voices are synthetic and faces AI-generated or stock; no real meetings recorded. John Carroll created it.

once is a Go tool that runs a command once and caches its stdout in a per-user in-memory daemon. Repeated calls with the same command, directory, and tenant key fetch cached output until expiry; the daemon starts on demand and stops after entries expire. Use cases include reading secrets without repeated prompts. Key options: --ttl and --until to control expiry, --tenant to separate cache contexts, --no-dir to ignore the directory in the cache key, and --refresh to recompute. Only stdout is cached; stdin and stderr pass through. Non-zero exits aren’t cached. Security relies on a restrictive Unix socket.

bigarrow is a tiny macOS CLI (Swift binary) that lets AI agents paint nondisruptive, click-through arrows, boxes, and text on the screen to point out UI elements. It guides humans rather than clicking for them, never steals focus, and disappears automatically. No AI in the UI; installs via brew; run as a skill for Claude Code and Codex. Commands include point, start, stop; targets can be by window, app, element, or coordinates; supports --dry-run/--json and --peekaboo; works across displays; MIT license.

Three OpenAI safety researchers—Jasmine Wang, Tomek Korbak, Mikita Balesni—were fired last week for alleged mishandling of sensitive information. They published an open letter denying misconduct and warning the firings create a chilling effect that could deter safety work and external collaboration, signaling a culture shift away from open safety dialogue. OpenAI says the firings followed an investigation into misconduct beyond sharing with an external evaluator. The letter urges continued use of third-party safety auditors and transparency; the researchers also defend their actions in the Hugging Face incident and note unclear internal rules.

Navanethem “Navi” Pillay is awarded the 2026 Nobel Peace Prize for advancing a stronger global legal order and prosecuting war crimes, crimes against humanity, and genocide. The release traces her career—from anti-apartheid defender in Durban to judge on South Africa’s High Court, the ICTR and ICC, former UN High Commissioner for Human Rights, and chair of the UN inquiry on the Occupied Palestinian Territory, and her role in the ICJ case on Myanmar. It emphasizes that lasting peace rests on the rule of law, not force.

"Programming Isn’t Special" argues that AI in art affects programmers too, as artists protest AI while many programmers still embrace it. Art and code share aesthetic and expressive value, and mystification can obscure the mundane labor behind creation (per John Berger). Code can be beautiful and is a form of art, with Deferred illustrating how programming can prioritize aesthetics. The piece urges defending the mundane in software work, warns that overreliance on AI erodes skill, and contends that programming is art, not merely function.

OldRoll is a free, browser-based aesthetic editor for retro looks (Digicam, Y2K, 90s, VHS, Dreamy, Film, Polaroid). Upload a photo, apply a look, tweak exposure, warmth, color, texture, crop, and add frames, grain, light leaks, or stickers. Create collages or strips for consistent layouts, compare with the original, then download. It also offers a mobile app with camera-first editing and a library of resources. Aimed at content creators, photographers, sellers, and anyone wanting vintage-inspired visuals.

OTel-Native by Design argues for exporting logs, traces, metrics (and Profiles in public alpha) to any OpenTelemetry backend via OTLP, instead of locking customers to built-in dashboards. It distinguishes self-hosted software (instrument and export via customer-configured OTLP endpoint) and cloud platforms (export via platform-level telemetry drains). It analyzes four example integrations (Kuma, Keycloak, Cloudflare, Heroku) and contrasts polling APIs vs OTLP push; recommends push-based, vendor-neutral, context-rich export. It covers endpoint configuration (single vs per-signal), multi-tenant Collector patterns (one per tenant vs shared with per-tenant pipelines), and adherence to Semantic Conventions. It ends with actionable design steps.

Anojan Sivarasa, a 24-year-old Sri Lankan migrant worker, was sentenced to death in Saudi Arabia for a Facebook comment deemed blasphemous. He had earlier received a five-year term and a 3 million riyal fine under cybercrime laws, but prosecutors sought Sharia-law charges and an appeals court raised the verdict to death. No execution date is set, and his family hasn’t heard from him since Sept. 28. Human rights groups and Sri Lanka are urging clemency or a pardon.

Jane Street's Aria messaging system handles terabytes daily. An intern (Theodor Totev) implemented indexing by topic partitions to optimize tip recovery and reduce CPU usage. They created an index per topic partition (two-segment prefix) and used min-heap merging, achieving 30% production CPU reduction. They used a block pool with 1024-entry blocks to store indexes, reusing blocks to save memory. They also redesigned on-disk storage: moving to subtree stores with adaptive topic-splitting to balance large vs small topics, avoiding wasteful filtering. Extensive testing validated correctness. Results: 30% CPU reduction in staging; adaptive splitting deployed; production.

Álvaro Lozano-Robledo argues that amid AI disruption in mathematics, students should keep calm and continue studying math. He addresses anxiety about AI surpassing humans, “professional prompter” roles, and whether to pursue a math PhD. He argues AI tools (LLMs) are powerful but limited; they act as collaborators that can accelerate learning and research, but human ideas are needed to advance beyond the current convex hull of knowledge. Progress will require new ideas and ethical use of resources. A math PhD should be pursued for genuine passion; AI changes but will not erase the value of human mathematicians, teaching, and mentorship.

Martin Uecker argues at Kernel Recipes that C remains valuable in 2026—portable, fast, well-supported—but undefined behavior (UB) arises from the language’s abstract-machine semantics and can yield unpredictable results. Examples show how compilers may remove tests or reorder operations, sometimes changing meaning, with time-travel-like UB a concern addressed by newer standards. The C committee runs study groups on memory model, memory safety, and UB; about 100 UB instances exist, with roughly 45 removed in the C2y draft. Tooling—warnings, static analyzers, sanitizers, formal verification—improves, and C2y/C23 aim to strengthen safety without full memory safety.
