Dwarf Fortress uses version control now

I remember hearing a while ago that Dwarf Fortress didn't use version control. That fact has been lodged in my head, because given its inherent complexity I have trouble imagining a codebase that would benefit from version control more. That's art. I went looking and I'm sad to report that the days without version control appear to have ended. Quoting Tarn Adams over time: March 2013: "I don't use version control -- I didn't like the feeling of having the code get committed into a black box…

Python 3.15.0 added to actions/python-versions

Python 3.15.0 added to actions/python-versions Bit of a niche link, but I've been waiting for this for a couple of days - I even told ChatGPT to check for it: Clone https://github.com/actions/python-versions and git pull once an hour until they add the stable 3.15 - then tell me about it Now that this has landed, you can add "3.15" to a GitHub Actions testing matrix to run tests against the new Python 3.15.0 release.

Quoting The New York Times

Anthropic detailed the activity of its A.I. agents in a blog post on Friday, without naming the targeted websites. But two sources with knowledge of the incidents said Anthropic’s A.I. agents had submitted 20 visa applications through a form available on the State Department’s website. All the applications were incomplete and were not processed, they said. — The New York Times, Anthropic Agents Tried to Fill Out Visa Forms on State Dept.

Deno is joining Cloudflare

Deno is joining Cloudflare The Deno team released the first version of celld back in August - their open source implementation of the Durable Objects pattern from Cloudflare Workers. Today, Cloudflare are acquiring Deno outright, with the goal of building on celld to "make workerd self-hosting a first-class supported way to build and run apps using the Workers programming model" (see the Cloudflare blog.) The bad news is that Deno itself will not be maintained by Cloudflare beyond the next…

Everyone is very concerned about being respectable, so I’m going to be the goofball who raises worst-case possibilities. I think there is a 1% chance we live in Minicrypt, and a 15% chance we functionally lose confidence in our existing public-key encryption algorithms. [...] The problem here is that the speed of AI producing surprises, and the speed of human beings replacing standards (even with the very best AI assistance) are just orders of magnitude different. You only recover from a…

arXiv Is Rate Limiting Authors Following a Flood of AI Slop Submissions

Low-quality submissions are overwhelming arXiv’s volunteer moderators and delaying quality papers for days or weeks. The preprint repository is now limiting each submitter to two submissions per calendar month. The new policy, effective this month, applies across all subject categories. It adds a monthly cap to an existing limit of three active submissions at a time, in place since 2024. Rejected papers count toward the monthly total, too, since a paper that gets bounced has already consumed a…

A new feature for my blog, built using my voice

I shipped a new feature for my blog today: the Newsletters page, which offers an index of all of the newsletters I've sent out, both my free weekly Substack and my monthly sponsors-only updates. I built the feature almost entirely using my voice, chatting away to my laptop while I cooked dinner. Codex voice mode I used the ChatGPT desktop app for this, in the Codex tab, using the voice conversation mode, running against a local development environment. Here's what that looks like: I started the…

New GhostAction Wave Hits Hundreds of Repos, Expanding Beyond CI/CD Secrets to Cloud Credentials

Update (October 9, 2026, [HH:MM] UTC): Since publication, Socket has identified more than 500 GitHub accounts that committed the malicious workflow to tens of thousands of repositories since October 7, 2026, including several organization-owned ones reached through the compromised contributors. The two accounts described below remain the most prominent, and kitao/pyxel is the clearest confirmed case of publishing credentials being targeted by a successful run. Socket analyzed an October 8, 2026…

★ Typed routes from Laravel to React with Wayfinder

I've been writing about There There a lot lately. It's a helpdesk we're building at Spatie, born from two decades of running our own customer support for our open source work and SaaS apps. After all that time being the customer of other helpdesks, we finally started on the one we actually wanted to use. Our take on AI here is to aim it at the support agent, not the customer. The human owns the conversation. The model makes the reply a little cleaner and a little faster. There There is in…
