I've released two updates of the Kanban Action Planner plugin for Obsidian today: 2.7.1 and 2.8.0. The big one is 2.8.0: time tracking you can start without opening a board, new ways to filter your cards, and new cards that show up the moment you create them. 2.7.1 is a cleanup release; nothing chan
The findability stack is my own model of the different layers of findability in a personal knowledge base. I couldn't find any published model that describes them, so I made one. Each layer is a fallback for the one above it, and resurfacing runs across all of them.
Google Docs can now open, edit and share Markdown files without turning them into Google Docs. You double-click a `.md` file in Google Drive, it opens in Docs, and it stays a `.md` file. Drive also gets a rendered preview for Markdown files.

Claude Code now compacts long sessions while you're away. Leave a big conversation alone for about an hour and, when you come back, the conversation shows `Compacted while idle, before the prompt cache expired`. From that point on, Claude works from a summary of what you did together.
On Wednesday (21 October), Anthropic announced Claude Duet, a "proactive agent" in research preview. It runs on Claude Opus 5.5, works in its own cloud computer, and keeps going while you're away.

Heretic is an open source command-line tool that removes refusal behavior from transformer-based Large Language Models (LLMs)). Its README calls that behavior "censorship (aka 'safety alignment')". You give it a model, and it gives you back a copy that answers most of the prompts the original refuse
The encoding specificity principle says that you retrieve a memory best when the cues available at retrieval match the cues that were present when the memory was encoded. Endel Tulving and Donald Thomson formulated it in 1973. When you store something, you never store it alone: it gets stored togeth
Here's a list of useful Personal Knowledge Management (PKM)) concepts, methods and best practices:

Effort tells Claude roughly how much compute you want it to spend on a task. In Claude Code there are five levels (`low`, `medium`, `high`, `xhigh`, `max`), and you can change it at any time with `/effort`. On Claude Opus 5.5 and Claude Fable 5.1, switching mid-conversation doesn't break the prompt
sys1 is an open-source inference server written in Rust by Alvaro Bartolome.

Six days after Claude Opus 5.5, Anthropic released Claude Sonnet 5.5, the second model of the Claude 5.5 family. Haiku 5.5 is next, "in the coming weeks".
Claude Code has many extension points, and since October 2026 mods add one more. Each one changes a different layer: what Claude knows, what it may do, which tools it has, and (with mods) how Claude Code itself behaves and looks.
On 7 May 2026, OpenAI released three new audio models in its Realtime API: GPT-Realtime-2, GPT-Realtime-Translate and GPT-Realtime-Whisper. OpenAI pitched them as voice agents that can reason, call tools, translate and transcribe while the conversation keeps going.
When Claude Opus 5.5 came out, I wrote about the price, the efficiency and the clearer writing (my launch take). Since then, I've used it for visual and creative work, and the results impressed me.
On 30 September, Google DeepMind announced Gemini 4 Argon, its new frontier model. Demis Hassabis called it "a huge step forward across key capabilities" on X. Koray Kavukcuoglu, who wrote the announcement, says it's already changing how Google works and builds internally.

"You can now mod Claude Code." @ClaudeDevs posted that on 1 October. Claude Code Mods are out of early access, and they're on by default since v2.1.287.
A few days ago, I wrote about letting Claude Opus 5.5 edit one of my YouTube videos. Three posts from late September show a related pattern: people ask Claude Opus 5.5 for motion graphics, and what they get back is code that renders the video.
Anthropic now runs a storefront: the Claude Marketplace, at claude.com/marketplace. The tagline is "Connect your apps, data and tools to Claude", and the page is split into Add, Buy and Scale:
Anthropic published a post on getting the most out of Claude Opus 5.5 in Claude and Claude Code. It reached 229 points on Hacker News on 3 October. I found the comments more useful than the post: people tried the advice on real work and reported what broke.
It's tempting to treat the effort setting in Claude Code as a smartness knob: the task feels hard, so you turn it up. After reading Thariq Shihipar's guide and the community numbers, I think that's the wrong mental model, and an expensive one.
