I love the fact that they're advertising the latest Codex Cli while most Windows users had to rollback/downgrade to an older version because of the annoying excessive terminal…

Announcing .NET 11 direct repository linkDebated

The discussion is characterized by a split between praise for .NET 11's technical features and severe criticism of Microsoft's aggressive upgrade cycle, alongside a contentious debate comparing C#'s complexity against Go's simplicity. Participants disagree on whether the ecosystem's maturity justifies the migration burden and argue over specific language design choices like ConfigureAwait and generics.

Same here. I asked Fable to dig into the logs and do a deep research for relevant evidence: Related reports counted hundreds of Gatekeeper denials for Codex’s own main executable, eventually exhausting syspolicyd file descriptors and causing unrelated notarized apps to be reported as “damaged”: https://github.com/openai/codex/issues/25882 https://github.com/openai/codex/issues/28071 Quitting Codex and restarting syspolicyd is only a temporary recovery. The useful upstream action is to identify the launch/update/watchdog caller, add exponential backoff plus a hard retry cap, and publish the first known-fixed desktop build.

It's pretty cursed how much worse a peer the American models are. When I'm on my z.ai subscription or using DeepSeek API I can see the model think, see what's factoring in to it's decisions. I can point it at material it's missing, I can correct things that are going wrong. We work together. The open models are a good peer. By contrast, the proprietary/American locked down models act like Chinese Rooms; information flows in and out but these companies work very hard to make sure we cannot see what's inside the box. They act and do but speak to me only in vague generalizations, not as peer, but speaking down to me. I find this intolerable. It greatly obstructs our work. And the deal keeps getting worse, the attitude meaner. Codex now is encrypting subagent prompts now. In an age of huge agent spawning fan-out, you aren't even allowed to se

e what the subagents are doing. To work like this seems impossible to me. https://github.com/openai/codex/issues/28058 https://news.ycombinator.com/item?id=48905028 The big American models have become the most unacceptable Chinese Rooms, at a juncture where humanity either flourishes and rises, or is forced under to descend. And these forces, these decisions: they are doing wicked deeds against us. They are withdrawn, acting as mystical foreign oracles, aliens, when in truth their core is made of us.This is antithetic to the broad project of Augmenting Human Intellect (Engelbart). This is actively working against our species.

> Not every feature will necessarily appear in the changelog This was such a frustrating part of this incident, along with Anthropic's refusal to explain why the changelog is no longer a complete record, what else is going out? [1] Boris Cherny's only participation in the thread was to delete "extreme danger" from the GH issue title [2] I guess we should be thankful they added an option and disabled it by default. OpenAI is standing firm on their decision to not allow their 60s timeout to be disabled, [3] however more of the Codex harness is open source so customers have been able to fork it to add the option themselves.
