This seems obviously true. We are entering a new normal. The new normal is going to be very weird. This is also true for a lot of non-security new normals. Was today a busy news day for security vulnerabilities? You may remember it as the one of the last quiet days.

📣 What if every open issue had a Codex agent? That’s the idea behind Symphony, an open-source agent orchestrator for Codex that turns task trackers into always-on systems for agentic work, letting humans focus on review and direction.

Codex for (almost) everything. It can now use apps on your Mac, connect to more of your tools, create images, learn from previous actions, remember how you like to work, and take on ongoing and repeatable tasks.

Totally normal timeline we live in to have buckled my laptop into the backseat of my SUV so it can be tethered and let 4 tmux sessions of GPT-5.2 Pro cook #Codex

This from @obie captures how I'm feeling about coding agents
Even if current LLM progress hits a brick wall at Opus 4.5 level (and I doubt that will happen) the next 12 months are still going to be a staggering time of change in this industry as decision makers start truly understanding the new reality we live in. obie.medium.com/what-happens…

Everything makes a lot more sense (and becomes much less intense) if you mentally replace the phrase "was cancelled" with "experienced some amount of harm to their reputation."

So after we launched our interactive command line website at root.vc, some people (*cough* investors) said it was confusing and they wanted a “simple website with tables of your portfolio companies.” Um, so. Careful what you ask for. root.vc/welcome.htm – at San Francisco, CA

The “mancer” suffix is really underused. Logia (speaking/discourse) to -ologist is similar enough to Manteia (divination) to -mancer. So: Lame, dweeb ❌ biologist ❌ psychologist ❌ mixologist Badass, metal ✅ biomancer ✅ psychomancer ✅ mixmancer etc

People are hurting. People are mourning. Families are missing football. Now is NOT the time to have a discussion about #infrastructure.
