I think the Airlines should take a stance on the shutdown and include a message in every delay/cancellation message. Or at the very least both sides it and include a message from each party blaming the other.

I didn't realize how large the increase in healthcare premiums was until I saw the numbers. How do you afford $920/month if your making 65K per year? That's 11K/year for people who probably have very little disposable income as is.

Forcing government employees to work without pay is the antithesis of free market capitalism. It's another example how the government constantly puts its finger on the scale. Republicans only have a problem when it benefits the majority of Americans.

AI is great for writing code.
Browsers are great for executing code.
CORS and other security measures are major blocker to many valuable apps. If we want to make browsers great for AI we need to make it easier for users to say I trust this app and relax CORS.

I've been using codex-CLI to build the AISRE UI I've been dreaming of for two years but lacked the capability to build. Yesterday I used it to add the ability to execute code inside web containers; it even figured out how to execute d3 code and make the results visible
Interesting impact of Claude Code:
I dabble with frontend, but not a frontend expert. I always reached for etiher some templates or something like Webflow to put together some landing page.
Now I started to... ask Claude Code to build me as per my spec.

I was playing with using webcontainers to add JS executability to my @runme.dev app. But when you enable the required headers that breaks OpenAI's chatkit which is served off a different domain.

AI is separating the production and consumption of information. If direct access to Wikipedia is dropping that suggests information consumers find AI mediated consumption more useful. This will impact the production of information; including the economic model
So for-profit AI companies have trained on the world's largest collaborative volunteer project and a precious free resource, to make money for their for-profit enterprises. They have crushed traffic to the volunteer project, starving it of donors and volunteers

I think People's intuition is that AISREs will solve problems the way humans do. I think this is unhelpful because it leads you to believe you just need to write down how humans solve ops problems. Notably you start thinking you can skip investing in evals.
