Big Think examines how vague neglect laws and safety anxieties have expanded government reach into everyday parenting, shrinking childhood independence. In Georgia, a 6-year-old’s unsupervised park ride led to a DFCS investigation and a later reversal of a neglect finding; that case echoes a broader push for "reasonable childhood independence" (RCI) laws, now in 11 states, that require "blatant disregard" for neglect. Proponents argue unsupervised time builds resilience; critics warn overprotection worsens anxiety and mental health. The piece underscores the need for triage in child welfare and a rebalancing of risk, autonomy, and safety.

Salvaged ML5A-MB1 motherboard with a Loongson 3A5000LL quad-core LoongArch CPU; the author builds a Debian box, tests cooling, RAM, and M.2 storage, and updates the socketed BIOS via Loongson firmware tools. After wrestling with BIOS/UEFI and a flaky Wi-Fi setup (ultimately bridging through an Airport Express), they install Debian 12, then upgrade to unofficial loong13/trixie for better support. Benchmarks show the 3A5000LL trails an Intel i5-3570 and Ryzen 3600X, landing around the 13th percentile, but Doom/Quake/Extreme Tux Racer run. The GPU (Vivante GC1000) supports OpenGL ES 2.0; overall the system is surprisingly normal for Loongson hardware.

Argues outsourcing hollowed out American workers’ bargaining power as production moves overseas (chips in Taiwan, clothes in Vietnam, cars in Mexico, services from India). Tariffs could revive domestic negotiation but risk an insular, less innovative economy. Critiques export controls on NVIDIA and the global AI frenzy, urging a society that prioritizes flourishing Americans over dominant, coercive power. Questions AI’s real impact on jobs and notes the long timeline. The author loves America and longs for a true “mandate of heaven”—peace, prosperity, and less corporate/bullying dominance.

The post presents a profile-based approach to road geometry using only lines and circular arcs. Profiles (cross-sections) define the road; the path is the interpolation of these profiles. Connecting two endpoints with prescribed tangents usually needs more than a single arc. The fix: a two-line fillet construction—extend continuation lines to their intersection and draw a circle tangent to both. If continuation lines don’t intersect, insert an intermediary profile chosen with a cubic Hermite spline, using its midpoint tangent. Edge cases are handled by design constraints; future work covers road intersections and networks. Footnotes discuss derivatives and inflection points.

RFC 3986 permits empty path segments; a double slash in an HTTP URL path denotes a zero-length segment and is syntactically meaningful. URL normalization does not include collapsing //, as that would alter the path’s segment sequence and the identifier. HTTP/URI normalization removes dot-segments and, for http(s), can map an empty path to “/” and apply scheme-based rules, but it does not collapse repeated slashes. Therefore, URLs like /furweb.git// and /furweb.git/ are non-equivalent unless the origin defines equivalence; some servers/tools may mishandle this, but it is not standard normalization.

Proposes a binary-level defense: rewrite every syscall instruction in a Linux binary at load time so a process talks only to a tiny, userland “library kernel” that implements about 40 syscalls. All other 410 syscalls are intercepted by a small shim inside a minimal VM. The process runs with 0F 05 replaced by a trap (INT3/NOP); a fast, in-VM dispatcher enforces policy, emulates calls, or backs off to the hypervisor as needed. JIT-generated syscalls are handled via a self-healing LSTAR patch. Result: near-native performance with full argument inspection and control over syscall behavior.

An order is a set with a binary relation obeying laws. Linear orders are total, reflexive, transitive, antisymmetric; with totality they form chains. Dropping totality yields partial orders (posets). Joins (least upper bounds) and meets (greatest lower bounds) generalize max/min; chains are linearly ordered subsets. Hasse diagrams illustrate relations; examples include color-mixing, divisibility, and inclusion of sets. Birkhoff’s representation: distributive lattices ≅ inclusion orders of join-irreducibles. Lattices are posets with joins and meets; bounded lattices have least and greatest elements. Preorders extend orders; preorders are thin categories, linking order theory to category theory via products/coproducts as meets/joins.

IPv6 is seen as more complex not because of its longer addresses, but because adopting a new protocol requires changing implementations, a new version, and interworking with IPv4. The 1990s IETF pursued IPng amid several proposals; the 1994 decision guided by RFCs led to IPv6 to tackle routing scalability and address exhaustion. Coexistence with IPv4—via dual-stack or translation—was recognized as unavoidable. Most deployment challenges come from IPv4/IPv6 coexistence rather than IPv6’s own design. Proposals like "IPv8" would not simplify the transition; bigger addresses were the core justification.

John M. Lindbakk introduces Brunost, a purely Nynorsk, interpreted language implemented in Zig. It enforces Nynorsk for identifiers and ships with a Nynorsk dictionary. The syntax covers immutable variables (fast), mutable ones (endreleg), conditionals (viss / ellers), functions (gjer, gjevTilbake), and loops (forKvart, medan). It uses imports (bruk) and try/catch error handling (prøv / fang). It can run in browsers and Wasm. The post shows examples (Hello world, Fibonacci, FizzBuzz, Conway’s Life) and notes Brunost is a playful, incomplete project with plans for libraries, docs, and tooling.

Interval Calculator is a GitHub project by Victor Poughon implementing interval union arithmetic: calculations over unions of intervals, e.g., [a,b] U [c,d], with the inclusion property guaranteeing the result contains the value from input choices. It supports arithmetic operations (+, -, *, /, exponent) and a union operator U, allowing nested intervals like [0,[0,100]]. Bare numbers are treated as narrow intervals. Full precision mode uses IEEE 754 doubles to bound results and preserve containment; a non-full-precision mode uses degenerate intervals and limits decimals. It provides functions, constants, and preserves disjoint unions; bug reports and future enhancements are noted.

Transcription, Lerner’s hybrid ‘séance,’ blends poetry, fiction and essays to probe fatherhood, aging, and media. An unnamed narrator interviews his 90-year-old mentor, Thomas, in Providence; when the narrator drops his phone, the ensuing interview is largely reconstructed from memory, a process that haunts the book’s second and third sections, which follow Thomas’s son Max and a family grappling with a daughter’s ARFID. Central is how voice, memory and fiction shape reality, with technology and parenting at its core. Written after Lerner’s heart surgery, it marks a tender, self-aware turn beyond The Topeka School.

trust-manager is an Emacs package (MELPA) that enables just‑in‑time trust management to reduce friction in Emacs’s security model, where Emacs 30+ marks files as trusted/untrusted. It prompts on first access per project; decisions persist. It auto-trusts init, early-init, custom files, and load-path. Untrusted Lisp buffers show a red '?' in the mode line, which you can click to trust and restore features. Settings live in trust-manager-trust-alist and can be edited with trust-manager-customize or dedicated commands; it hooks into forgetting projects. Install via MELPA or from Git sources. Author: Eshel Yaron.

Casus Belli Engineering describes how organizations respond to visible failures by scapegoating a foundation component and replacing it with the advocate's preferred worldview. Rooted in Girard's scapegoating theory, the mechanism relies on crisis, rivalry, and collective imitation; insecure leaders craft a narrative that assigns guilt to a proximate foundation and promotes a replacement aligned with their technology or methodology. In software, Agile is a case: Waterfall becomes the scapegoat, agile branding disguises replacement as progress. The piece warns that real causes (testing gaps, error handling) survive, and calls for rigorous root-cause analysis and resisting rhetoric in favor of engineering evidence.
