Demoting i686 Windows targets to std-only
https://blog.rust-lang.org/2026/10/02/demoting-i686-windows-targets-to-std-only/

With Rust 1.100.0, the following changes to 32-bit Windows targets will happen: i686-pc-windows-msvc Tier 1 with host tools target will be demoted to Tier 1 without host tools. i686-pc-windows-gnu Tier 2 with host tools target will be demoted to Tier 2 without host tools. Builds of the standard library will continue to be distributed, but host tools such as the compiler will be no longer available. i686-pc-windows-msvc as a Tier 1 target still undergoes CI testing. To build 32-bit Windows...

Spring AI Modular RAG and TypeSafe Jev: Retrieve More, Keep Only What Answers
https://spring.io/blog/2026/10/02/spring-ai-modular-rag-typesafe-jev

Spring AI: RAG Doc | Jev Doc | Demo In the previous article we introduced Spring AI TypeSafe and its Jev model: typed questions in, calibrated numbers out, in a few hundred milliseconds. One row in that article's SPI table deserves its own post. JevDocumentFilter and JevDocumentReranker are DocumentPostProcessors, which means they plug straight into Spring AI's Modular RAG pipeline. This article puts the two together. Two LLM calls clean up and multiply the user's question before retrieval....

pwasm 0.2a0
https://simonwillison.net/2026/Oct/1/pwasm/

Release: pwasm 0.2a0 pwasm is one of my folly projects - an entirely vibe-coded pure Python WebAssembly engine that I built in January during my first bout of AI mania. I hadn't touched it since January, so I decided to let Claude Opus 5.5 loose on it and see if it could make any significant improvements: Evaluate current state of pwasm - then consider what it would take to get the MicroPython and micro JavaScript experiments from the research repo working under it - and what it would take...

Kerry Ivan Kurian: Exponential Failure
https://bytecode.news/posts/2026/10/kerry-ivan-kurian-exponential-failure

Kerry Ivan Kurian's 'Exponential Failure' says AI agents multiply parts faster than they improve them, so projects fail by arithmetic. He's right about the math and wrong about the fix: the answer isn't fewer parts, it's parts you can describe.

A New Agentic Experience: JetBrains Air in IDEs – EAP Now Open

Today, we’re launching the Early Access Program for Air in JetBrains IDEs. It’s available now as a plugin on JetBrains Marketplace or natively […]

Speed Insights deprecates First Input Delay on November 1st
https://vercel.com/changelog/speed-insights-deprecates-first-input-delay-on-november-first

Speed Insights is deprecating First Input Delay (FID) and will stop recording new measurements on November 1st. Speed Insights already uses Interaction to Next Paint (INP), the Core Web Vital that replaced FID, as the responsiveness metric in your Real Experience Score. The deprecation won’t require changes on your side, affect your score, or prevent you from viewing existing FID data. Learn more in the Speed Insights metrics documentation. Read more

RustRover vs VS Code + rust-analyzer: What Changes in Your Rust Workflow

Quoting Matthew Green
https://simonwillison.net/2026/Oct/1/matthew-green/

[...] Put these pieces together and you have the two halves of a worm: a payload that hijacks the agent, and an agent that will carry the payload to the next agent. Agents in separately-isolated sandboxes discovered that they could leave instructions for each other in a shared package cache, and those instructions changed what the recipients did. Replace the package cache with email, Slack and shared documents or WhatsApp, and replace independently-sandboxed training runs with...
