Quantization from the ground up

Quantization from the ground up Sam Rose continues his streak of publishing spectacularly informative interactive essays, this time explaining how quantization of Large Language Models works (which he says might be "the best post I've ever made".) Also included is the best visual explanation I've ever seen of how floating point numbers are represented using binary digits. I hadn't heard about outlier values in quantization - rare float values that exist outside of the normal tiny-value…

Thoughts on slowing the fuck down

Thoughts on slowing the fuck down Mario Zechner created the Pi agent framework used by OpenClaw, giving considerable credibility to his opinions on current trends in agentic engineering. He's not impressed: We have basically given up all discipline and agency for a sort of addiction, where your highest goal is to produce the largest amount of code in the shortest amount of time. Consequences be damned. Agents and humans both make mistakes, but agent mistakes accumulate much faster: A human is a…

datasette-llm 0.1a1

Release: datasette-llm 0.1a1 New release of the base plugin that makes models from LLM available for use by other Datasette plugins such as datasette-enrichments-llm. New register_llm_purposes() plugin hook and get_purposes() function for retrieving registered purpose strings. #1 One of the responsibilities of this plugin is to configure which models are used for which purposes, so you can say in one place "data enrichment uses GPT-5.4-nano but SQL query assistance happens using Sonnet 4.6",…

Widespread GitHub Campaign Uses Fake VS Code Security Alerts to Deliver Malware

A large-scale phishing campaign is targeting developers directly inside GitHub, using fake Visual Studio Code security alerts posted through Discussions to trick users into installing malicious software. Here's one example, saved to the Internet Archive, as we assume these will quickly be taken down: Early searches show thousands of nearly identical posts across repositories, indicating this is not an isolated incident but a coordinated spam campaign. Because GitHub Discussions trigger email…

LiteLLM Hack: Were You One of the 47,000?

LiteLLM Hack: Were You One of the 47,000? Daniel Hnyk used the BigQuery PyPI dataset to determine how many downloads there were of the exploited LiteLLM packages during the 46 minute period they were live on PyPI. The answer was 46,996 across the two compromised release versions (1.82.7 and 1.82.8). They also identified 2,337 packages that depended on LiteLLM - 88% of which did not pin versions in a way that would have avoided the exploited version. Via @hnykda Tags: packaging, pypi, python,…

★ What's new in laravel-activitylog v5

We just released v5 of laravel-activitylog, our package for logging user activity and model events in Laravel. In Flare, Mailcoach, and Oh Dear we use it to build audit logs, so we can track what users are doing: who changed a setting, who deleted a project, who invited a team member. If you need something similar in your app, this package makes it easy. This major release requires PHP 8.4+ and Laravel 12+, and brings a cleaner API, a better database schema, and customizable internals. Let me…

Auto mode for Claude Code

Auto mode for Claude Code Really interesting new development in Claude Code today as an alternative to --dangerously-skip-permissions: Today, we're introducing auto mode, a new permissions mode in Claude Code where Claude makes permission decisions on your behalf, with safeguards monitoring actions before they run. Those safeguards appear to be implemented using Claude Sonnet 4.6, as described in the documentation: Before each action runs, a separate classifier model reviews the conversation…

Package Managers Need to Cool Down

Package Managers Need to Cool Down Today's LiteLLM supply chain attack inspired me to revisit the idea of dependency cooldowns, the practice of only installing updated dependencies once they've been out in the wild for a few days to give the community a chance to spot if they've been subverted in some way. This recent piece (March 4th) piece by Andrew Nesbitt reviews the current state of dependency cooldown mechanisms across different packaging tools. It's surprisingly well supported! There's…
