In a near-future-release of Automic Vault we have added ssh-agent support. Automatically allow ssh connections for trusted destinations. Require human approval for everything else. Human approval can happen on the iPhone app. eg. allow your Terminal automatically and deny your agents. You can delete the keys from ~/.ssh/ after import. Keys are properly encrypted in the keychain. Related

I'm confused. Isn't the Speaker of the House of Representatives literally the most senior member of that particular branch of the US government? Who exactly is "upstairs" to him? Quoting @RepThomasMassie I predicted they’d call off Congress until the election to stop our new Epstein bill. Johnson said on TV that was “stupid” and “nonsensical.” But then he got a call from “upstairs” and canceled Congress from the middle of September until the election. government Related

I even switched to local CI, you know, like DHH inspired where I don't care so much more about the CI on GitHub. We still have it. It's still, it still has a place, but I just run tests locally and if they work locally, I push to main.

And remember that DeepSeek happened in times of crisis, urgency, not in times of comfort. A lot of these technological breakthroughs and leapfrogging happens in times of crisis. This is called crisis innovation. And you got to thank the US for that. When the Chinese were comfortably importing chips from the US, the whole industry stalled for 20 years.

A korrent is a belief a person has stated in their own words: one
sentence stating the claim, backed by a quote and a source, kept at
korrents.com .
Under a name here, the quoted block is what they actually said.
The korrent beneath it is the claim those words support, in
korrents' wording — tap it to see the record, its source, and who
else holds it.
Nobody here wrote their own korrents. They are compiled from public
statements, and a person can change their mind, which is recorded too.

About the English under a post
Some people here publish in a language other than English. Where they
do, this site shows a machine translation beneath the post, in
this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the
serif above is exactly what the person published, and it is what to
quote them on. A translation can be wrong in ways that matter,
especially about tone.
Only the post's own words are translated. A quoted post, a linked
article and a belief on korrents.com
are left in their original language.
