Shirt Pocket announces SuperDuper! 4, a ground-up rewrite of the macOS backup tool after 22 years. It replaces Documents with Copy Jobs, inline configuration, and a real-time preview of what would happen. It speeds up with Smart Updates (2x–) and Turbo; a typical 8‑million‑file, 2.5TB run drops from ~40 minutes to ~1 minute. It runs as a background helper/server; copies can run with no UI and in parallel. It supports any Mac file system, Copy Rules, Shortcuts integration, and optional shell scripts. Requires macOS 14+; paid upgrade with discounts; free for qualifying recent purchases.

NASA kept Voyager 2 running for another year by trimming its power draw from the plutonium-powered RTG. Engineers shut off nonessential devices and switched to low-power options, leaving three active science instruments instead of ten. The adjustment, nicknamed the “Big Bang” power shift, conserves energy as power fades by about four watts per year. Voyager 1 is set to receive a similar treatment in the coming months.

The Nixpkgs core team has disbanded after 10 months of governance, citing unsustainable, lightweight leadership and burnout. They cite achievements such as reforming committer delegation, onboarding 19 committers, extending the merge bot, reestablishing GitHub contact, securing an Enterprise Cloud upgrade, triaging a GitHub security incident, and starting an automation/AI policy. They attribute ongoing governance failures to systemic Steering Committee issues—poor communication, micromanagement, lack of delegation instinct, and slow progress on GSoC, grants, AI policy, moderation, and GitHub org reform—making autonomous decision-making untenable. They’ll reduce involvement and won’t seek SC roles, hoping for future delegated leadership.

An open repository documenting a clean-room reverse engineering of Captain Bible in the Dome of Darkness (1994 DOS game). It provides a reproducible FreeDOS/QEMU environment and research notes, with the original CB/ data kept Git-ignored. The project includes a Rust-based clean-room engine (SDL3 frontend), a suite of analysis tools (Rizin, Python, mdBook), and living documentation in docs/ and spec/. PLAN.md and progress logs track activity, and results are published as mdBook books. Setup uses run.sh to launch the emulator with a persistent image; deterministic comparisons and rebuilds are supported. Docs publish to GitHub Pages.

Five years after proposing curlese, curl remains the universal language for diagnosing broken HTTP integrations. The core problem—two teams, opaque logs, and a firewall—persists, but curl output now provides executable evidence that can be pasted into tickets, or fed to an LLM for context. What changed: HTTP/2, HTTP/3, widespread mTLS, and edge defenses (WAFs/proxies) complicate failures; a single curl -v repro often pins the issue. The 2026 survival kit adds flags for timing, DNS bypass, mTLS, JSON payloads, retries, and a -w one-line autopsy. Updated symptoms-to-culprits dictionary and starter phrases round out the guide.

The U.S. Department of Energy launched the Genesis Open Models initiative, unveiling Genesis-Science-1 with Arcee as the first open-weight foundation model for scientific research. The program, part of the Genesis Mission, aims to accelerate discovery by providing transparent, adaptable AI models for domains from materials discovery to biology and high-energy physics. A DOE-hosted portal opens today for open-weight contributions, with first-round applications due August 14, 2026. Tracks cover foundation-stage data and post-training data/environments; reviews use five gates. Universities, national labs, industry, and research organizations may apply.

Ben Zhang lost his phone at the office and Find My was disabled by MDM. He asked Claude for help, which suggested tracking Bluetooth signal strength and quickly generated a meter to do so. He used it, watched the signal rise, and found the phone. He shared a GitHub repo (ben-z/findphone) for the tool, prompting discussion about Bluetooth radar and bespoke personal software.

Angus Cheng explains that some PDFs encode trailing minus signs invisibly by drawing the minus in the same gray as the background, causing amounts like $110.00- to appear negative when parsed. This alignment trick helps right-align numbers but hinders data extraction. Two fixes are proposed: OCR the PDF to render and read as images, or strip out non-black text (ignore colored text)—the latter requires the extractor to track text color.

Retired General Paul Nakasone (ex-NSA) told DEF CON that water-system controllers (PLCs) must not be internet-connected, as at least 12 US states have seen water hacks, likely by Iran. The FBI is investigating attacks on operational technology. Iran-linked groups have targeted PLCs for years, and researchers say Iran is behind the recent disruptions. Nakasone warns of a vast attack surface—about 50,000 water municipalities supplying 90% of US water. Defense requires a collaborative approach with partnerships, such as DEF CON Franklin and Project Chimera, to harden critical infrastructure.

Guarded methods encode per-method constraints on the receiver via a type equality witness. OCaml lacks dedicated syntax, but you can encode constraints with type ('a,'b) eq = | Refl : ('a,'a) eq. For example, flatten requires ('a,'b list) eq to prove the receiver is a list, while sum requires ('a,int) eq. Interface: class type ['a] obj_list = object (self) method length : int; method append : 'a list -> 'a obj_list; method uncons : ('a * 'self) option; method flatten : ('a,'b list) eq -> 'b list; end. Implementation uses a helper with Refl to enforce the constraint, preserving normal message passing.

REpsych is a proof-of-concept by Christopher Domas showing how a program’s control flow graph (CFG) can generate an image. It translates input images into functioning programs so the CFG renders the original image. To create a program from an image, save it as a 24 BPP bitmap in gfx/, then run make image. Two executables are produced: repsych_v1 and repsych_v2, each with a different CFG-placement strategy. Tips: keep images small (≤100×100); for text, convert to 2 BPP BW before 24 BPP for best results. BSD-3-Clause.

John Gruber critiques Apple’s rejection of Terry Godier’s iOS app Dark Hours, arguing it is strictly astronomy, not astrology, and that the claim of a live tarot feature is mischaracterized. He praises the app’s design and usability, contending it should be celebrated and approved, as such errors undermine the App Store’s value for developers and users.

An engineering leader shares a curated “Required Reading” list of technical articles and books to help teams digest wisdom from experienced programmers. The list highlights lessons on clean coding, architecture choices, and practical tradeoffs (anti-ORM stance, frontend simplicity, locality of behavior, YAGNI, parse-don’t-validate). It covers Coding practices, Platform, Frontend, Databases, Async, and Encoding, plus notable books such as The Design of Everyday Things, Designing Data-Intensive Applications, Crafting Interpreters, Category Theory for Programmers, and The Mythical Man-Month. Articles are annotated with why they matter, and some opinions may be contested.

AI coding at scale drives rising costs; the article argues for a playbook that preserves broad access while keeping spend predictable by pursuing the efficiency frontier. Four cost levers: (1) adopt open-source or cheaper models and use a meta-harness to retain flexibility; (2) dynamic routing (request- and task-level, plus escalation) to use the lowest-cost capable model (Unity AI Gateway shows savings); (3) visibility and spend gates with progressive friction rather than hard caps; (4) reduce token overhead via context compression, lean harnesses, and prompt caching. It promotes a centralized AI Gateway (Unity AI Gateway + Omnigent) with open tooling.

Assembly Hall of Shame, by Christopher Domas, seeks the absolute floor of single-instruction latency rather than speed. It builds leaderboards of how slow a single instruction can run on stock hardware by hammering MMIO/PCIe and forcing microarchitectural delays. The x86 leaderboard is led by fxrstor64 on Ryzen 7 5800H, with ~198,002,498,236 cycles (~62 seconds). Other entries include wbinvd, rdrand, cpuid, wrmsr, rdmsr, and more. Rules: one instruction scored, no interrupts, no hardware mods, timings normalized to base clock.
