VS Code inserting 'Co-Authored-by Copilot' into commits regardless of usage
VS Code was silently inserting 'Co-Authored-by: GitHub Copilot' into git commits even when users weren't using Copilot β€” and without showing it in the commit message UI. One of the approving engineers posted a public apology in the HN thread. This is a significant breach of trust around git history integrity, with real implications for code attribution, IP, and what Microsoft's AI-first push is doing to engineering culture.

Kimi K2.6 just beat Claude, GPT-5.5, and Gemini in a coding challenge
Kimi K2.6, an open-weights model from Chinese lab Moonshot AI, topped a competitive programming benchmark over Claude, GPT-5.5, and Gemini. Open-weights frontier models from Chinese labs are increasingly competitive, which has real implications for compute gatekeeping narratives and Western AI moats.

AI Self-preferencing in Algorithmic Hiring: Empirical Evidence and Insights
Empirical paper finding that AI-powered hiring systems exhibit 'self-preferencing' β€” systematically favoring candidates who themselves used AI tools during the application process. This has concrete economic and labor market implications and is the kind of feedback loop that's hard to detect without careful measurement.

A couple million lines of Haskell: Production engineering at Mercury
Mercury, a fintech startup, runs millions of lines of production Haskell β€” a rare real-world data point on what serious functional programming at scale actually looks like. Covers engineering tradeoffs, hiring, tooling, and what it means to bet on a language most engineers consider exotic. High-craft engineering perspective.

This Month in Ladybird – April 2026
Monthly progress update from the Ladybird browser project β€” an independent, from-scratch browser engine with no legacy Chromium or WebKit code. For someone who builds things from scratch to understand them, this is essential reading on what it takes to implement a real browser in 2026 and where the project stands.

Six Years Perfecting Maps on WatchOS
An indie developer's six-year deep dive into building maps on watchOS β€” a constrained platform with severe memory, rendering, and API limitations. The kind of craft-focused engineering writeup that rewards careful reading; full of specific technical decisions and the patience required to do one hard thing extremely well.

LLMs do fine on ARC-AGI-3 if they are allowed to search over game logs
A finding that LLMs perform significantly better on ARC-AGI-3 when given access to game logs and allowed to hill-climb over search β€” suggesting the benchmark's difficulty is highly sensitive to harness design, not just raw model capability. Important nuance for how to interpret recent ARC-AGI-3 results.

Why the A.I. Job Apocalypse (Probably) Won’t Happen
Ezra Klein argues the AI job apocalypse probably won't materialize the way Silicon Valley predicts β€” not because AI isn't powerful, but because of how labor markets, productivity gains, and demand expansion historically interact. Worth reading critically given the counterpoint from the job posting data (Article 215).

Everyone talks about agi timelines, hardly anyone talks about compute gatekeeping
A Reddit thread making the underappreciated point that compute concentration β€” not just algorithmic progress β€” is a binding constraint on AGI's societal impact. If OpenAI, Microsoft, and a handful of others control inference at scale, model breakthroughs may not democratize the way open-weights advocates hope.

Spotify adds 'Verified' badges to distinguish human artists from AI
Spotify is adding 'Verified' badges to distinguish human artists from AI-generated music. A platform-level signal that AI content labeling is becoming a real product feature, not just a policy debate β€” with implications for how music discovery and monetization will evolve.

California to begin ticketing driverless cars that violate traffic laws
California will begin issuing traffic tickets to autonomous vehicles that violate traffic laws. A regulatory step toward treating AVs as accountable road users rather than experimental hardware β€” the 'no driver to blame' legal gap is starting to close.

Neanderthals ran 'fat factories' 125,000 years ago (2025)
Archaeological evidence from 125,000 years ago shows Neanderthals systematically processed large animal bones to extract fat β€” suggesting sophisticated, planned food processing behavior well before modern humans. Quietly rewrites assumptions about Neanderthal cognition and behavioral complexity.

Do_not_track
A shell script tool for opting out of various telemetry and tracking systems across common developer tools and platforms. Practically useful for anyone who cares about what their dev environment is phoning home, especially relevant given the VS Code/Copilot attribution story.
