Houdini and Blender Export Identical Plant Geometry, Differing Mainly in File Size

·1 views

A test compared Houdini 22 and Blender 5.2 by exporting the same controlled plant from shared prototypes and fixed placements. Both exports retained 6,076 triangles, three vertex-color groups and two wind attributes, with a maximum position difference of 0.000000082 metres. Two early failures, degenerate leaf tips and lost colours in the first Blender material setup, surfaced only through checking the data rather than the export button. The author stresses the study measures editable assembly and deliverable data, not which application is faster or better for procedural modelling in general. The GLB files differed in size and normal handling, so file size alone does not indicate exporter efficiency.

Musk Reportedly Buys $1B Stake in CNN's Parent Company

Reports indicate that Elon Musk has acquired a stake worth roughly $1 billion in the parent company of CNN. The details come from a linked news item shared on Hacker News, which has drawn only limited discussion so far. The source material provided does not include the full article text, so specifics such as the exact ownership percentage, transaction date, and stated rationale cannot be confirmed here. Further reporting would be needed to verify the terms and any official statements from the companies involved.

Voice and chat AI agents gave conflicting answers on fees and availability at one dental group

A four-clinic dental group in Ohio used one vendor and one knowledge base for both its AI phone agent and its web chat agent, yet the two channels answered the same questions differently. An audit of 60 conversations per channel found contradictions on rescheduling fees, insurance acceptance, appointment length, and same-day availability. The most costly case involved the chat agent citing a $25 late-rescheduling fee while the phone agent said there was no charge, which led customers to doubt the stated pricing. The inconsistencies were attributed to system prompts written separately with different priorities, voice-specific brevity that dropped policy qualifiers, and separate feedback channels that never compared transcripts. The suggested fix is a canonical answer table for money- and commitment-related questions, with channel-specific wording that must keep all qualifiers.

MockMini releases v0.1.0, a small auditable macOS proxy core of about 2,600 lines

MockMini, a compact proxy core written in C and Swift, has reached its first tagged release, v0.1.0, under an Apache-2.0 license. It supports Shadowsocks, VMess, Trojan and VLESS over TCP, TLS or WebSocket, running on its own bounded userspace TCP/IP endpoint. Unlike larger kernels such as mihomo, Clash or sing-box, it avoids vendored proxy kernels, third-party TCP/IP stacks and the Go runtime, so one developer can review the whole codebase. Its packet engine is fuzzed, with about 99% line coverage, and continuous integration runs sanitizers and checks against a pinned Xray release. The project still lacks features such as gRPC, Reality and SACK, and its throughput trails mature kernels, while its maintainers invite reviews and contributions.

Spirula Studio's Vulkan build trains a 100,000-splat Garden scene for Three.js

A test of Spirula Studio's Windows Vulkan build used the official Mip-NeRF 360 Garden sample with supplied camera poses. The 2,000-iteration training run produced a 100,000-splat scene in about 13.6 seconds of total process time. The 24.80 MB PLY file was converted to a 1.95 MB SPZ file and rendered in a local WebGL scene using Spark 2.4.0 and Three.js 0.186.1. The author notes the test did not cover other GPU vendors, new phone captures, or production use in the Digital Garden.
