The key moment is when Elizabeth Holmes is on speakerphone and Nathan asks her if she knew Amanda Seyfried was in the room. Holmes says: "I'm not sure." What she means is: "I'm not sure if saying yes or no is to my advantage here." Quoting @Noahpinion The movie does a great job of helping regular people understand two very different types of liars. The first type intentionally deceives people. The second type creates a fantasy world for themselves and other people to inhabit. The second type is much more dangerous.

Hi Daniel, With all the nonsense going on related to AI slop bug reporting and PRs, just looking in from the outside is exhausting, I imagine it must be even worse for you and the other contributors. I wanted to say thank you for all the time and energy you put into cURL, the tool really is a joy to use and never lets me down. energy AI slop

Been charging my EV #offgrid for 2 years now and up to 2.25 megawatt hours total. That's $1000 saved over using public fast chargers. Not bad for a way to use excess power from the #solar system, which was not really designed to charge an EV, just to always have enough power at home. After some upgrades, I expect it will be closer to 1.5 mwh/year going forward. solar

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.
