• It uses one configuration file plus Git hooks to control branch flow, checks, and lane behavior.
• It is positioned as a zero-cost local alternative to GitHub Merge Queue with commands for landing, syncing, previewing, and promotion.

Recursive Filters: SMA, EMA, Low‑Pass, and a Tiny Kalman

Key Points

• Recursive filters are presented as low-memory, low-latency tools for smoothing noisy streaming measurements.
• The article compares SMA, EMA/low-pass filtering, and a simplified 1D Kalman update, highlighting their trade-offs.
• It concludes that SMA is simple, EMA/low-pass is a practical default for streams, and tiny Kalman filtering adds adaptive behavior when noise is known.

Starter Homes Are Piling Up While Luxury Homes Fly Off the Market

Key Points

• Starter-home inventory rose nationally, but starter-home sales still fell year over year.
• Luxury-home inventory tightened while luxury sales increased, showing stronger high-end demand.
• San Francisco showed one of the sharpest splits, with luxury sales surging and starter-home sales declining.

Flume Water Monitor 915 MHz Security Is Pretty Good

Key Points

• The Flume sensor-to-bridge RF link was reverse engineered and its encryption was defeated with moderate effort.
• The protocol uses frequency hopping in the 902.5–927 MHz band, 2-FSK at 200 kbps, CRC-16, and AES-128 ECB on the payload.
• The article says effective key strength fell to 44 bits, enabling a GPU-based brute-force attack in about a day for under $10.

Angels in Coptic Magic I: Introduction

Key Points

• The article defines angels in Coptic magic as divine intermediaries active in both heavenly and material realms.
• Coptic magical texts drew on Greek, Jewish, and Christian ritual and literary traditions.
• The post introduces major textual models for angelic hierarchy, including magical papyri, Sefer ha-Razim, and On the Celestial Hierarchy.

A pharmacy chain in Vermont implemented AI for efficiency

Key Points

• Kinney Drugs’ AI refill assistant rollout was followed by customer reports of errors, delays and communication failures.
• The AI tool, Burt, was built by Synerio, and Kinney Drugs’ terms acknowledge the system may contain inaccuracies or omissions.
• The article links the case to broader concerns that healthcare AI adoption is moving faster than privacy and consumer protection regulation.

NSF pilots 4-year PhDs with industry research placements

Key Points

• NSF is funding a five-year, $47 million pilot for a four-year Ph.D. model with built-in industry research placements.
• The program aims to serve more than 250 doctoral students and is supported by universities and private industry.
• NSF says the pilot is designed to better align STEM doctoral training with the reality that many graduates pursue industry careers.

Logic for Programmers by Hillel Wayne

Key Points

• The book teaches programmers how to use logic for practical software design, testing, verification, and reasoning.
• It covers topics from Boolean logic and property testing to Dafny, Alloy, TLA+, SMT solving, and Prolog.
• The book is available in DRM-free digital formats, with code samples on GitHub and a print edition on Amazon.

Kuna: Decompiler Development in the Age of Coding Agents

Key Points

• Kuna is a newly released experimental decompiler built largely with LLM-written code and designed for autonomous refinement.
• The article reports benchmark results placing Kuna close to IDA Pro 9.2 in control-flow structuring on C programs.
• Basque says Kuna relies on prior open-source decompiler research, especially Ghidra and angr, and still requires scientific evaluation methods rather than fully automatic research.

Thanatos Rising

Key Points

• Einstein asked Freud in 1932 to address the question 'Why War?' as part of a League of Nations-linked intellectual exchange.
• The article contrasts Einstein’s pacifism with Freud’s skepticism about giving simple answers to the problem of war.
• The correspondence unfolded as Nazism was rising in Europe, and the published pamphlet was later barred in Germany.
