David Tracy chronicles building the world’s first brand-new WWII Willys MB in his LA driveway, using mostly eBay-sourced parts for a 900‑mile Moab road trip. The Autopian partnered with eBay Motors, sourcing a Manila-made body and frame from MD Juan and a Go-Devil engine from France, aiming for 75% new parts and 90% from eBay. He recruited three wizkids—Brandon Girmus, Étienne Boisseau—and later Laurence for 20 days. After months of wrenching, setbacks (lifters, vapor lock, brakes, cooling), the Jeep finally ran and conquered off-road trails, proving The Autopian’s community-driven mission.

Vanguard-Map is a real-time 3D browser map of global moving assets—live ships (AIS), aircraft, satellites, submarine cables, and space weather—plus terrain and ocean simulation. It offers time scrubbing, scenario replay, and physics-based anomaly detection via invariants, rendered on a 1.5M-point terrain cloud. Built with Three.js as plain ES modules (no build step). Run by cloning the repo, serving the folder (npx serve . or python -m http.server 3000), then loading a local or live AIS key (aisstream.io); optional Cesium ion token for high-res terrain and a local flight proxy for flights. Architecture uses per-domain managers and vg1:* events.

pgrust is a Postgres rewrite in Rust that now passes 100% of Postgres’s regression tests, targeting Postgres 18.3 and booting from a 18.3 data directory. It aims to keep Postgres behavior while exploring deeper server changes with Rust and AI-assisted development. It’s not production-ready or optimized yet; some extensions (e.g., PL/Python, PL/Perl, PL/Tcl) aren’t fully compatible. The repo includes Docker and build-from-source instructions, a regression runner, and a roadmap for multithreaded internals, connection pooling, JSON workloads, and faster forking. License: AGPL-3.0.

AI slop starts with the codebase itself. AI code quality depends on the model’s training data and the codebase context. Common tech stacks give the model leverage; proprietary or inconsistent code requires extra teaching within a limited context window, increasing cost and lowering quality. Compare: (1) clear specs and a consistent codebase → fast, accurate implementation; (2) inconsistent, legacy code with extra docs → more inference, slower, pricier results. A rewrite to establish clear, consistent patterns can amplify AI’s strengths, changing rewrite economics by reducing teaching time and boosting output quality.

AI’s data-center boom hinges on delivering electricity, not just generating it. Stargate campuses demand about 1.2 GW peak, and worldwide AI compute could reach 100 GW by 2030 if growth stays strong. The bottleneck is grid interconnection: backlogs, rigid first-come, first-served rules, and costly restudies. Median interconnection time rose from under 20 months in 2005 to about 55 months in 2023. Reforms: cluster studies, cost-sharing for backbone upgrades, and auction-based fast-tracks; encourage energy-only service (connect-and-manage) and demand response; plus on-site batteries to ease grid strain. Flexibility in grid design, not just generation, powers the AI era.

Nextest is a next-generation Rust test runner, up to 3× faster than cargo test, with a modern UI, per-test isolation, and strong CI support. It provides powerful test filtering, filtersets, per-test settings, and the ability to record, replay, and rerun tests (including Perfetto traces and JUnit XML output). It can archive and partition tests across workers, supports setup scripts, and integrates with editors/IDEs. Runs on Linux, macOS, Windows, with pre-built binaries or from source. Doctests are not yet supported. Licensed under Apache 2.0.

Databricks built an internal benchmark to compare coding agents on its multi-million-line codebase across languages (Python, Go, TypeScript, Scala). They evaluated models and harnesses on real PR tasks, analyzing cost versus performance and task complexity. Key takeaways: the best performance sits on a Pareto frontier of OpenAI, Anthropic and open models; GLM 5.2 is viable for daily coding at lower cost; token price is a poor predictor of end-to-end cost; harness choice dramatically affects cost and quality (Pi vs native); models cluster into three capability tiers. They advocate mixed models, cheaper mid-tier use, and automatic model/harness selection.

MechCommander’s “left arm bug” misallocates large weapons into the left arm due to a flawed distribution fallback. The author uses embedded debugging symbols to map weapon classification (large vs small) and discovers Desperate Measures weapons are incorrectly treated as small. They patch the executable by locating a code cave and changing the large-weapon fallback from 0 to 2, which distributes large weapons across arms and side torsos. A secondary patch (default-to-large) reclassifies Desperate Measures weapons and trims space. They also publish a patcher on GitHub and note caveats for modders.

An avid LLM user reflects on heavy daily use of Claude Code, Codex, and other tools for designing, reviewing, and writing code, with a side stream of unsupervised agents and browsing for answers. He notes greater productivity but growing burnout: repeatedly encountering false assumptions, hallucinations, abrupt writing, emojis, and monotonous patterns. Personalization helps little; he can’t control others’ styles, and the repetition wears him down. He remains pragmatic about LLMs but is unsure how to cope with the fatigue, though he doesn’t plan to stop using them.

Frugon is a free, local, open-source LLM cost analyzer that runs entirely on your machine to identify where your LLM spend leaks. It ingests OpenAI-style JSONL logs, either via a local proxy shim (frugon capture) or by writing JSONL directly, and calculates costs, suggests model routing to reduce spend, and optionally samples traffic (--measure) using your keys. It supports installation via uvx frugon analyze or pipx, runs fully offline, and outputs a shareable savings report. Six commands: analyze, capture, models, update, pricing, quality. MIT licensed by Rodiun.

HTTP 406 Not Acceptable: the server cannot provide a valid representation of the requested resource (/computation/uts35/), and even the ErrorDocument handling failed to process the request.

Remote attestation uses TPM-protected measurements to prove a host's boot state (hardware, firmware, kernel/init, root filesystem). PCRs hash measurements; EK/AK establish trust, and LDevID provides provenance. A verifier challenges the device; if measurements match, the host can obtain TLS certs or be allowed to run workloads, proving provenance and restricting access. This builds a trusted boot foundation (measured boot) for further security, but runtime protection rests with EDR and policies. Upgrades can break seals; use TPM2_PolicyAuthorize to authorize new PCR values.

TryAI compared Grok 4.5, GPT-5.5, Claude Opus 4.8, and Claude Fable 5 by building the same three HTML apps: a 3D Rubik’s Cube, a particle gravity sandbox, and a Breakout game. Round results: Opus 4.8 and Fable 5 nailed the cube on first try; Grok 4.5 lagged at first but recovered; GPT-5.5 faltered on the cube. In the sandbox, GPT-5.5 delivered the most mesmerizing visuals; in Breakout all four were playable. Overall, Grok 4.5 offered the best speed and cost; Opus/Fable were the most reliable builders; GPT-5.5 was fastest at short prompts but pricier. TryAI suggests testing yourself.

Blog post arguing median makes a solid interview question. It explores design choices: should the input be sorted in place or copied, and mutation implications; API design and performance; an off-by-one trap; even vs odd length handling; and why median can be preferable to mean. It emphasizes testability and standard library knowledge. The piece includes a Python example: median(numbers) raises on empty input, uses sorted to avoid mutation, computes the middle value (or average of two middle elements) accordingly, with discussion comments.
