Chrome DevTools MCP now lets coding agents connect to active Chrome sessions, reusing existing browser sessions and accessing debugging data in DevTools (Elements, Network). To use it, enable remote debugging in Chrome (chrome://inspect/#remote-debugging) and configure the MCP server with --autoConnect. When connecting, Chrome prompts for permission and shows a “controlled by automated test software” banner. The feature (beta in Chrome M144) enables seamless manual/AI debugging; setup steps are detailed in the post.

An Atlantic essay by Charlie Warzel examines why many older adults spend more time on digital devices and why their children and grandchildren worry. It asks whether this concern is justified or a projection of younger generations’ anxieties about screen time. Katty Kay interviews Warzel, exploring tech’s impact on family relationships and loneliness among seniors.

Bill Wadge honors his late PhD advisor, John W. Addison Jr. (1930–2026), recounting how Addison’s precise, elegant logic teaching at UC Berkeley shaped his career. He recalls Addison’s tough yet brilliant courses in model theory and definability, and how Addison steered him to a breakthrough via an infinite-game approach and a Hartley Rogers paper, yielding his Borel-set work and a 350-page dissertation. Wadge notes Addison’s generosity, his Berkeley network (Gödel, Tarski, Kleene, Church), and how Addison’s mentorship influenced his own supervision and the Lucid dataflow work. Addison’s spirit lives on in his descendants.

C++26 deprecates ellipsis parameters without a preceding comma to improve C compatibility and reduce confusion with parameter packs. Deprecated forms include void f(int ...); void g(auto args ...); template<class T> void h(T ...); The comma-separated forms (void f(int, ...); void g(auto args, ...); template<class T> void h(T, ...);) remain valid and preferred. Standalone ellipsis (void f(...);) stays valid. The change is non-breaking and can be automated, clearing space for future features like homogeneous variadic parameters.

LATENT learns athletic humanoid tennis skills from imperfect human motion data—motion fragments that capture primitive tennis skills, not complete match sequences. By extracting priors from these quasi-realistic motions and applying correction and composition, it trains a policy that consistently returns balls to target locations with natural motion. The approach includes robust sim-to-real transfer designs and is deployed on a Unitree G1 humanoid, achieving multi-shot rallies with human players in the real world.

The piece argues that prompt injection is an infrastructure risk, not only a model-safety issue, as browser, memory, and multi-agent handoffs can leak data or cause harmful actions from untrusted content. It traces 2025–2026 developments: expanding attack surfaces (web, email, tool calls, memory), public incidents like the MCP GitHub exploit leaking private data, and defender strategies (least privilege, per-task credentials, signed cards, memory-origin tracking, cross-agent policies). It concludes security must be built in: per-repo scoped credentials, tool signing, memory controls, and auditable data flow; some residual risk will remain.

Zipp 2001 Restoration, Part 1 recounts Ben Katz’s discovery of a late-1990s Zipp 2001 frame (one of about eight variants) and his plan to modernize it. He tests removable dropouts to widen hub spacing for 11s/12s and add a disc-brake mount, using a UDH hanger for safety. A 5-axis machined prototype dropout is produced and anodized. He documents a gaudy paint plan—primer, dark base, blue sparkle flake, multiple clear coats—tested on a fork before applying to the beam. The post ends with machining a new seat clamp; more parts are forthcoming.

River 0.4.0 splits the Wayland stack by running the window manager as a separate process, coordinated with river via the river-window-management-v1 protocol. This preserves frame-perfect rendering and low latency, while giving window managers full control over placement, keybindings, and policy. The protocol splits state into window-management state and rendering state, with atomic manage and render sequences so no per-frame roundtrips are needed. Benefits include easier WM development, crash isolation, and support for high-level languages. Limitations target 2D desktop use (no VR or wobble effects). Aiming for river 1.0 with broader WM compatibility.

Trust no one: one-way Windows domain trusts can be exploited in practice. The trusted-domain account created for a trust (the TDO) stores the trust password and Kerberos inter-realm keys on the trusting domain. A new tool, tdo_dump.py (Impacket-based), can extract the TDO from the trusting domain, revealing the TRUST_ACCOUNT password and Kerberos keys, enabling an attacker with Domain Admins on the trusting domain to authenticate to the trusted domain and perform typical AD attacks. Thus, one-way trusts can effectively be bidirectional in practice, enabling lateral movement.

At Palantir's AIPCon, CEO Alex Karp defended the company's role in military kill chains, saying they're proud to help warfighters and that some casualties are inevitable; he warned AI's dangers and shifts in power. The conference showcased Maven for Targeting Workflow (integration of reconnaissance-to-action), ShipOS for the US Navy, and an extended Airbus Skywise partnership. Healthcare demos included Care Progression Navigator and Reforge, a Joint Commission 'healthcare data router' project. Other examples highlighted real-time patient flow and AI-enabled workflows; Palantir portrays its platform as universal across sectors, despite controversy.

Generative AI doesn’t make software more productive; lines of code remain a poor productivity metric. Programming is about expressing ideas and managing complexity, not rapid code production. LLMs can speed coding but encourage premature implementation, raise maintenance costs, and hinder collaboration and support. The piece advocates prioritizing design, reusable libraries, and thoughtful tradeoffs over sheer code volume, and calls for explicit questions about productivity, value, and cost rather than assuming more code equals better outcomes.

The piece contrasts the size of modern compilers with small, practical ones: a 1500-line C subset and a 500-line Lisp compiler can function effectively, suggesting large codebases add many features through seams and kludges rather than essential functionality. The author then details sixteen months of work on a physical project—digging, bending, barren patch of dirt—named Seams/Landscapes/Kludges, with a plaque and seeds, as a tangible start, and frames it as part of the 'Modern GDSL' effort to post about their work.

This piece covers the first material‑programming workshop on the Kniterate knitting machine, funded to train students and experiment with our knit tools. Attendees create a 100‑stitch cast‑on template organized in layers, then compare the Kniterate interface to the knitout visualiser and CMU tools. The session explores plating rib structures, front/rear transfers, and bind-offs, and notes how waste yarn and feeder placement affect results. A pattern from Rosie is knitted after a few trials. Reflections suggest knitout visuals are less usable for knitters than the Kniterate view, underscoring the need for clearer, knitter‑friendly visualisations.
