⚠️⚠️⚠️⚠️ An RCE vulnerability in PHP core! ALL VERSIONS AFFECTED. Only PHP 8 will receive patches. https://x.com/h4x0r_dz/status/2112620404309184734 https://www.php.net/archive/2026.php#2026-10-20-1 Make sure to update your servers ASAP tomorrow when patches are released. The release is scheduled for Wednesday, 21 October 2026 at 14:00 UTC Because once they're out in public, vulnerabilities will be exploited throughout the internet for sure. 🤯 Via @s13k_ (My idea was disconnect all my servers from the web before it, then update PHP, then test if it's safe, then put them back online?)
The PHP security team is giving advance notice: Upcoming security release Wed, Oct 21st 2026, 14:00UTC, two critical vulnerabilities, both rated CVSSv4 9.2. PHP users are encouraged to prepare to update. Earlier release if details become public or active exploit evidence.

View quoted postgreat points by caspar on what makes building a "company harness" (companyOS? org harness?) hard and how MDA solves them!
How do you build a company harness? We've built internal agents at LangChain across marketing, sales, and engineering. The results have been incredible but these agents were NOT easy to get right. We spent a ton of time solving the problems that come with a multiplayer harness.

The results have been incredible but these agents were NOT easy to get right. We spent a ton of time solving the problems that come with a multiplayer harness. Every agent team landed on the same core primitives: - It lives where people already work (for us that's Slack) - It knows who's asking and acts OBO that person for some services and with its own identity for others - It has memory, scoped globally and/or at the user level - It runs code in a sandbox where authenticated CLIs and scripts just work (gh, curl, your internal APIs) - Large % of its runs are scheduled rather than explicitly invoked by someone (ambient agents!!) It became clear we needed one shared place for these primitives, so we built Managed Deep Agents. In my humble opinion it is the easiest way to build a company harness today Our docs are very agent-friendly, point them here to get started: http://langch.in/mda
RT Eli Gaultney Seriously, OpenClaw is so good now. I'm starting to see a real gap in skills between people who haven't yet set up a personal agent and those who have. It's not scary!
@_infinati Yeah in January, a month in! Before we created a non-profit around it and made it good.
View quoted postRT Nicholas Larus-Stone Day 2 of “An agent a day keeps Phase 2 failures away” -- AI for increasing creativity Apparently yesterday was too tame, so let’s spice it up with a Hypothesis Dreamer Agent. When used appropriately, AI can actually be a great source of creativity. No one (including AI) knows your science better than you do. But sometimes you need to integrate ideas from other people, other teams, or the broader literature. And that’s exactly where an agent which is constantly synthesizing your research with broader context and dreaming up new hypotheses can help. Sample prompt (feel free to tweak): Please create a Weekly Hypothesis Generation Agent that looks over my work, my team’s work, and the published literature to suggest new hypotheses. These can include new research directions, ideas on why a particular experiment isn’t working, or ways our work could be improved. Give a prioritized list of 3-5 actionable suggestions. Please present all of the sources you used to come to this conclusion. If it’s helpful, please use visual references to understand the reasoning behind the suggestions.
