Bluesky Over the past few days, I've taken the time to summarize my thoughts on the recent incidents involving agents’ misaligned behavior. We don't know with certainty what comes next, but we know where these issues originate, and this can help us plan the path forward. English, from French Ces derniers jours, j'ai pris le temps de résumer mes réflexions sur les récents incidents impliquant des comportements inappropriés d'agents. Nous ne savons pas avec certitude ce qui va suivre, mais nous savons d'où viennent ces problèmes, et cela peut nous aider à planifier la voie à suivre.

A fixed, forward, insufficiently defended logistics hub is a single point of failure; its loss propagates faster than any combat loss of ships.

energy
Their words
If you keep asking this question, what you realize is energy is the fundamental input. When we figure out AI and robotics that allows us to do semi-aututonomous manufacturing, energy will become the cost of all things, right? The cost of buying a thing will become the cost of energy used to make it.

there's as populations become more apart, there begins to be biological incompatibilities rapidly developing, probably as the square of the distance separation, because you need pairs of interacting genes, and therefore it's the square of the separation.

Bluesky Happy Pi Day! In a certain sense, π is not a constant, but a variable. Using our usual Euclidean distance, it is 3.14159… but applying other L^p norms on ℝ², half the unit circle's perimeter will give other values. For instance, at p=1 (taxicab geometry), “π” = 2√2. At p ≈ 2.2, it's 3.20. Related

energy
Their words, before
we will see batteries aggressively displace transmission as the most cost-effective way to ensure continuity of electricity supply, leading to an eventual pruning of the grid and drastic reduction in the average distance that power travels between production and consumption, even as the average time that power is stored increases.

A confession in prep for my next blog article: 6 months ago I started a program of Testosterone Replacement therapy, after learning about it from my friend Kevin @Camp4 who had just started a company which does it. I thought I'd be at least helpful as test subject for their protocols, but it turned out to be much more: my life has been semi-transformed, in the form of maybe a 50% boost in all areas of life. It's pretty big. So now I am encouraging any friends who are men friends in the 45+ age group to consider learning more about this stuff, and to make sure their next blood test includes a… Quoting @Camp4 There’s a lot of noise and misinformation out there about testosterone.

Decoded is a semi-autobiographical book that tells Jay-Z's story growing up and finding success in hip hop. It also helps you deeply understand the inner-city ghetto struggles (Jay was actually a drug dealer until age 27). In organized sections of hand picked songs with RapGenius-style lyric explanations (note: Decoded came first), you see through his eyes the difficult choices he and so many others faced while listening to some of his best tracks.

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

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.
