@TakoTreba @Airbnb Ironically the best way to get anything done with Airbnb customer support is to email Brian directly. I had a similar experience, wrote Brian and it was resolved in my favor in an hour.

On Sunday evening, I had the worst experience I’ve ever had with @Airbnb. A few hours before arriving in Hamburg for OMR, a conference that brings more than 70,000 people to the city, my booking was suddenly cancelled. I immediately contacted customer support, expecting them to help me find another place. Instead, they told me they couldn’t assist because “Airbnb didn’t cancel your booking, the host did.” Excuse me? This happened around 11 PM. I spent the entire night on calls with customer support and did not sleep at all. At around 1 AM, things got even worse. I received a message saying I was no longer allowed to make bookings on Airbnb because my account had been flagged as potentially dangerous. I honestly couldn’t believe what was happening. I was traveling with my three-month-old baby. I explained that multiple times. It made no difference. No meaningful help. No travel credits. My account was blocked. And by the time I arrived in Hamburg, I had to scramble to find a hotel on my own. The ironic part? There was no AI involved in this experience. Only humans following scripts and passing me from one person to another. And, Brian, I genuinely wish I had been dealing with AI instead. It would have been faster, more logical, and probably far more empathetic than the people I spoke with that night. What shocked me most was realizing how few real alternatives there are to Airbnb. At midnight I was completely on my own trying to solve a problem that should never have happened in the first place. Worst customer experience I’ve had in years.

@benhylak The ChatGPT interface doesn’t work for this. We’ve already tried it.

@steipete how does it not just gloss over stuff and consider it "done" prematurely? Still having issues with this in 5.5

Ghostty is leaving GitHub. I'm GitHub user 1299, joined Feb 2008. I've visited GitHub almost every single day for over 18 years. It's never been a question for me where I'd put my projects: always GitHub. I'm super sad to say this, but its time to go. mitchellh.com/writing/ghostt…

Tibo@thsottiaux·
With Codex the there is quite the gulf in load between peak and off-peak times, and we would like to achieve more of a smoother traffic pattern as that would be a more optimal use of our compute. We have ideas, but curious what you all think we should do? Would more usage during off-peak and surge multiplier during peak times make sense?

"Using coding agents well is taking every inch of my 25 years of experience as a software engineer, and it is mentally exhausting. I can fire up four agents in parallel and have them work on four different problems, and by 11am I am wiped out for the day. There is a limit on human cognition. Even if you're not reviewing everything they're doing, how much you can hold in your head at one time. There's a sort of personal skill that we have to learn, which is finding our new limits. What is a responsible way for us to not burn out, and for us to use the time that we have?" @simonw

"Using coding agents well is taking every inch of my 25 years of experience as a software engineer." Simon Willison (@simonw) is one of the most prolific independent software engineers and most trusted voices on how AI is changing the craft of building software. He co-created Django, coined the term "prompt injection," and popularized the terms "agentic engineering" and "AI slop." In our in-depth conversation, we discuss: 🔸 Why November 2025 was an inflection point 🔸 The "dark factory" pattern 🔸 Why mid-career engineers (not juniors) are the most at risk right now 🔸 Three agentic engineering patterns he uses daily: red/green TDD, thin templates, hoarding 🔸 Why he writes 95% of his code from his phone while walking the dog 🔸 Why he thinks we're headed for an AI Challenger disaster 🔸 How a pelican riding a bicycle became the unofficial benchmark for AI model quality Listen now 👇 youtu.be/wc8FBhQtdsA
