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…

Quoting Matthew Green

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…

ttok 1.0

Release: ttok 1.0 I released ttok 0.4, ran uv tool upgrade ttok, piped a file into the new version... and realized that it was defaulting to the GPT-4 tokenizer when it should very clearly default to GPT-5/GPT-6 instead! I figured switching the default was a reasonable excuse to finally ship a 1.0. OpenAI haven't actually confirmed that GPT-6 uses the same tokenizer as the GPT-5 family yet - there's an angry issue about it - but I found this commit by William Liu which reports on an experiment…

ttok 0.4

Release: ttok 0.4 ttok is my CLI tool for counting tokens, using OpenAI's open source tiktoken library. It hasn't been in updated in a couple of years, but I finally fixed a Click warning, updated CI, and added a --list-models command to list available models. It works with uvx, so you can count tokens in anything like this: cat file.txt | uvx ttok Tags: projects, ai, openai, generative-ai, llms, tokenization

Quoting Carson Gross

Computer programming is, fundamentally, about two things: Problem-solving using computers Learning to control complexity while solving these problems I have a hard time imagining a future where knowing how to solve problems with computers and how to control the complexity of those solutions is less valuable than it is today, so I think it will continue to be a viable career even with the advent of AI tools. — Carson Gross Tags: computer-science, carson-gross, careers, ai

The Preservation Gap in the AI Stack: Why Capability Is Advancing Faster Than Reconstructability

Artificial intelligence systems are difficult to reproduce because their behavior depends on nondeterministic models and on data, configurations, policies, and external services that continue to change. But exact reproducibility is not always what operators, investigators, or auditors need. They often need something different: historical reconstructability. The central claim is that reconstructability is a system property […]
