Posthorn is a self-hosted outbound mail gateway that bridges your apps to a transactional email provider (Postmark, Resend, Mailgun, AWS SES, or outbound-SMTP). It offers three ingress options—HTTP form, HTTP API, and SMTP—and funnels all to a single Go-based transport. It’s not a mail server or marketing platform. Quick-start Docker deployment is provided, plus server-to-server API mode and an SMTP listener. Production setup requires SPF/DKIM/DMARC, reverse proxy, rate limiting, and approved origins.

BadHost CVE-2026-48710: Starlette <1.0.1 builds request.url from the Host header and path, letting attackers forge request.url.path to bypass path-based auth. Affects Starlette/FastAPI apps that use request.url.path in middleware, including vLLM, LiteLLM, MCP servers, and other AI infra. The X41 D-Sec/Nemesis scanner automates MCP-endpoint discovery and tests Host-header bypass in three modes: MCP Server, AI Infrastructure, Custom. Fix: upgrade Starlette to 1.0.1+, avoid path-based auth middleware, and use endpoint-based security (Depends/Security). Deploy an RFC-compliant reverse proxy to normalize Host headers; prefer scope['path'] if needed.

Joyce Johnson meditates on how Jack Kerouac’s fame outpaced the man she knew and how his life left a sea of artifacts. She traces relics: ashes from his last cigarette in a Grolier Club display; the vast archive sold by his heirs; the On the Road manuscript, sold for millions; and her own Kerouac collection—his red-and-black shirt, meals, letters, and photos from their 1957–58 orbit in Greenwich Village. The piece sketches a love affair born amid Beat frenzy, then waning as fame sharpened his loneliness and drinking, leaving Johnson with a memory as tangible as any relic.

AI hasn’t transformed law because structural barriers block diffusion. A two‑layer data moat exists: (1) access to comprehensive, curated case law databases (Westlaw/Lexis/Clio vLex) and (2) the editorial infrastructure that makes them usable. Open data and Me‑Tise approaches chip away at the moat, but many firms still struggle with fragmented data, poor governance, and nonstandard workflows. Organizational conservatism and the billable‑hour model slow value capture; risk and liability concerns, including the supervision gap as AI handles whole workflows, deter adoption. ABS structures and niche AI firms spark innovation, yet scale and access to justice remain unresolved.

Clint Hocking, veteran designer, argues that realistic, diffuse lighting in modern games makes stealth harder to read, blurring light, shadow, and safety cues. He says baked lighting in older titles was clearer and that current ray tracing and diffusion require deeper design thinking to sustain stealth. The piece cites historical examples (Thief’s light gem, Splinter Cell) and notes ongoing Splinter Cell remake work with Ubisoft layoffs; Hocking has since founded Build Machine Games to pursue new stealth projects.

Elizabeth Davidson traces the history of obituaries in American newspapers from ancient death notices to today’s digital memorials. Early notices were rare and biased toward the wealthy and prominent; printing innovations widened publication. The Civil War produced long casualty lists and sentimental obits, while the postwar era celebrated lifetimes and included more women and Black citizens. The linotype era expanded obits for ordinary people, and by the 1930s–40s the four-part format became standard. Today online platforms extend and reframe obituary practice.

The just-say-no engineer slows development and enforces high quality, a gatekeeper role that thrived during ZIRP (2008–2022) when companies hired aggressively and needed control over sprawling codebases. With ZIRP’s end, layoffs followed and firms shifted to delivering value, often blaming AI. AI tools now pressure these engineers to say yes, challenging their identity, and their once-valued stance is being punished. They won’t vanish but may need to move into pure engineering or other domains where quality matters, as the end-of-ZIRP environment reshapes expectations.

An ode to LAN parties, highlighting their social intimacy and low-latency appeal of local multiplayer. Once dominant in the 1990s, they declined in the 2000s due to faster Internet, gaming cafés, and DRM-driven publisher reticence, with online matchmaking and platforms like Discord taking over. Although large events like DreamHack persisted, the bite-sized, friend‑driven LANs remain memorable. Today, hosting is easier—laptops, Wi‑Fi, snacks—preserving a unique communal gaming experience that the author believes everyone should try at least once.

An opinion piece arguing that labeling AI as merely “next-token prediction” hides its capitalist impact: it accelerates labor displacement, concentrates production in a few hands, and transforms workers into replaceable nodes. It traces data-harvesting via opt-out defaults, massive datacenters, and lab funding, while executives push “solved” AI and national-security justifications. It warns of privacy erosion and a race to monetize humanity’s output, leaving most people with diminished economic mobility in a rent-seeking system.

Calvin Flegal's post describes Migo Games, a social arcade for Mac/iOS (and web) built with Elixir/Phoenix on the back end and Swift/SpriteKit on the front end, hosted on Fly.io with Postgres on Crunchy Bridge. The project emphasizes a lean binary (a few MB) and minimal dependencies. He praises Elixir for its fault tolerance and process-model fit (rooms), and notes faster Mac build times and better iOS performance vs web. AI aids development but doesn't replace hard challenges like user acquisition; he invites readers to try the games and leave reviews.

An engineer re-implemented a Rust web app (Axum/Tera; ~14.9k Rust lines) in Ruby on Rails to test a quick conversion with local LLMs. A comparative audit (Rust/Axum/Diesel vs Rails vs Rails+Sorbet) rates Rails as the best overall option (~1.47x better outcomes). The conversion took about 30 minutes, yielding a 77% reduction in lines (14,943 Rust lines to 3,322 Ruby lines). Ruby looks clean; typing via Sorbet/Agents may improve safety, and testing should be easier with Rails tooling (VCR). The author plans to explore further and notes impressive hardware and testing workflows.

Texas A&M researchers report a two-dose intranasal therapy using extracellular vesicles loaded with microRNAs that reach the brain and reverse aging-related cognitive decline in animal models. The spray reduces chronic neuroinflammation by dampening NLRP3 and cGAS-STING signaling, and restores mitochondrial energy, improving memory and recognition for months after treatment. If proven in humans, it could offer a noninvasive approach to dementia and brain fog, possibly replacing invasive procedures. A patent has been filed; study funded by the NIA.

Republishing the 1944 Simple Sabotage Field Manual, the piece argues modern organizations sabotage themselves by becoming ultra-bureaucratic. It shows how “do everything through channels” and similar tactics mirror today’s inefficiencies, explaining how bureaucratic dysfunction slows productivity despite tech advances. The suggested cure isn’t more rules but removing bureaucracy—a task hampered by growing middle management. The author proposes AI-enabled “fuzzy interfaces” that adapt to people, potentially letting scale occur without institutional sclerosis.

AI tools don’t weaken engineering judgment; passive use does. The real risk is abdication—accepting AI-suggested solutions without questioning creates hidden debt and can slow you down when failures occur. The remedy is adversarial use: treat AI output as a draft from a smart junior, then interrogate it—edge cases, assumptions, production implications, and security. The generate‑interrogate‑revise loop sharpens judgment and keeps you thinking with the tool. The author emphasizes deliberate practice through weekly, practical AI workflows available for free via The AI Leverage Weekly.
