Show HN share on Hacker News rose from about 2–3% (2012–2022) to over 12% by December 2025, likely fueled by LLM-enabled coding posts (Claude Code, Cursor 1.0). Meanwhile, average Show HN scores declined—from about 19.53 to 9.04—suggesting lower quality or reader fatigue. The author analyzed BigQuery data, classified Show HN posts by titles starting with 'show_hn:', exported to CSV, with Python code on GitHub. Determining LLM usage is hard since many posts don’t mention it; updates planned every few months.
macOS runs hundreds of background processes, with backupd and backupd-helper from Time Machine using CPU and memory even when Time Machine is disabled. These processes are controlled by LaunchDaemons in the Signed System Volume, and most LaunchDaemons and LaunchAgents can’t be modified on modern macOS. Since macOS Sierra, Time Machine scheduling is handled by DAS and CTS via XPC, and com.apple.backupd-auto is dispatched hourly regardless of user settings. Even in a VM with Time Machine off, scheduling persists. Conclusion: due to SSV and DAS-CTS, user-level slimming of macOS is minimal; macOS isn’t designed for it.
Gore Verbinski calls Unreal Engine the “greatest slip backwards” for movie CGI, arguing its gaming aesthetic is seeping into cinema and harming photo-real realism. He says Unreal is replacing Maya in some VFX pipelines, hurting lighting, subsurface scattering, and creature animation, producing an uncanny valley. Verbinski cites Mandalorian virtual sets and films like The Matrix Resurrections and Quantumania as examples of Unreal’s influence. In his film Good Luck, Have Fun, Don’t Die, he still uses CGI but aims for at least 50% of the frame to be photographic to stay honest.

EU lawmakers delayed ratifying the EU–US trade deal in response to Donald Trump’s threats to impose Greenland tariffs. The move signals discontent and leaves room for retaliatory steps if Washington acts. The bloc had planned to vote on removing tariffs on US industrial goods as part of the agreement reached last July after months of wrangling that included 15% EU tariffs. The delay does not derail the deal, but Brussels will weigh options at an emergency summit, including pausing the pact or imposing up to €93 billion in tariffs; Macron backs coercive tools.
Vermaden chronicles building an ultra-light FreeBSD desktop (FreeBSD 15.0-RELEASE with Base PKGBASE, XLibre X11, Openbox/Tint2/Dzen2) on a UFS filesystem with Soft Updates instead of ZFS. He lays out install/config steps (loader.conf, rc.conf, sysctl.conf, devfs.rules), packaging minimal tools, and no login manager (uses xinit). RAM measurements show an idle Openbox desktop using about 206 MB RAM (230 MB observed minus small process costs). In a 220 MB VM, plain FreeBSD uses ~82 MB and the Openbox setup ~134 MB. Concludes 200 MB RAM desktop is feasible.
An in-depth guide of 113 production-ready agent patterns from real systems, organized into eight categories: Orchestration & Control; Tool Use; Context & Memory; Feedback Loops; UX & Collaboration; Reliability & Eval; Learning & Adaptation; Security & Safety. It frames the Christmas 2025 surge as production readiness, highlights foundational patterns (Plan-Then-Execute, Inversion of Control, Reflection Loop, Chain-of-Thought Monitoring) and multi-agent patterns (Swarm Migration, LATS, Tree of Thoughts, Oracle/Worker). Emphasizing human-in-the-loop, strong security, a maturity model, and practical steps: pick a few patterns, build a library, iterate, and share.

Bound Book Format (BBF) is a DirectStorage-native, high-performance binary container for digital comics and manga. It enables rapid append and random access with 4KB-aligned assets and memory-mapped I/O for direct GPU transfers and reduced CPU bottlenecks. BBF uses per-asset XXH3 hashes for integrity and deduplicates identical pages. The layout includes header, page data (AVIF/PNG), string pool, asset and page tables, section and metadata tables, and a footer. It supports hierarchical sections (volumes/chapters), mixed codecs, and verification. The bundled CLI tool bbfmux manages creation, verification, extraction, and info; MIT licensed.
The GDB JIT interface article explains how GDB can debug JIT-compiled code using two approaches. The classic interface requires the runtime to expose __jit_debug_register_code and __jit_debug_descriptor, create in‑memory ELF/Mach‑O objects for each JIT function, and link them into a descriptor list so GDB can attach symbols and lines; this is why projects like V8, LuaJIT and ART ship large JIT glue. The newer approach lets you write a custom debug info reader (a loaded shared object) that implements an interface (read/unwind/get_frame_id, etc.) to supply symbols and line data. It also discusses perf-map ideas, O(n^2) linked-list costs, and GC considerations.

Anthropic's original performance take-home is open for you to try. The repo provides a version of the original challenge to beat Claude Opus 4.5 with unlimited time. Benchmarks (clock cycles) compare Claude Opus 4 variants and Sonnet 4.5, e.g., 2164 cycles (Opus 4 after long compute), 1790 (Opus 4.5 casual), 1579, 1548, 1487, 1363. If you optimize below 1487 cycles, email [email protected] with code (and resume) for potential interviewing. Run tests/submission_tests.py to verify thresholds. Files include perf_takehome.py, problem.py, Readme.md.
Humanoid and Siemens completed a proof of concept using Humanoid’s HMND 01 wheeled Alpha robot in Siemens’ Erlangen Electronics Factory to automate tote-to-conveyor destacking. The two-phase POC included a physical twin and a two-week on-site run, demonstrating autonomous operation and real-world readiness. Target metrics were met: 60 tote moves per hour; support for two tote sizes; autonomous runs over 30 minutes; uptime over 8 hours; overall pick-and-place and autonomous pick-and-place success rates above 90%. The partners see this as a first step toward a broader collaboration and potential rollout of humanoid robots across Siemens facilities.
Disaster planning for regular folks advocates level-headed, data-driven emergency prep. It urges readers to map realistic risks, prioritize common, manageable hazards over sensational doomsday fantasies, and build a practical lifestyle of readiness. Core "commandments" cover: save money and protect savings; avoid unnecessary debt; learn transferable skills; get in shape; foster neighborly ties; write a response plan and will; plan for safety and security; and maintain sensible gear. The guide details water and food stockpiling, fuel and power basics, essential tools, camping/hygiene gear, medical and protective supplies, and simple self-defense and online safety. The aim: confidence and resilience, not panic.
Verizon has begun enforcing a 365-day lock on phones bought via its TracFone subsidiary, returning to the pre-2021 policy after an FCC waiver. New phones activated on or after Jan 20, 2026 must be paid-for and active for a year before they can be unlocked on request; automatic unlock after 60 days no longer applies. The change covers TracFone and its prepaid brands (Straight Talk, Net10, Clearway, Total Wireless, Simple Mobile, SafeLink, Walmart Family Mobile). Phones purchased before Jan 20, 2026 remain eligible after 60 days. Visible also adopts 365 days.
Snapshot testing captures a known-good API response and compares future responses to a baseline to catch regressions. It offers fast test creation, broad coverage of large payloads, and readable diffs, but risks nondeterminism from dynamic data and snapshot fatigue. Mitigations include scrubbing timestamps/IDs, using placeholders, or ignoring fields. A Kreya example shows enabling snapshots for REST/gRPC, saving a baseline, running checks against new responses, reviewing diffs, and updating snapshots when intentional. Not a silver bullet, but high-ROI for complex APIs.
ScratchTrack brings Git-style version control to audio production. It tracks every recording, edit, and mix as commits, lets you branch to experiment, and merge ideas back with conflict-aware collaboration. Features include multi-track recording with take management, offline access, and export of stems or full mixes as WAVs. Work flows: record, branch, share for collaboration, merge. Pricing: Free for solo projects; Pro ($10/month) adds cloud sync and collaboration. macOS native app (requires macOS 14+).
