Science journalism or materials science?

New comment by texaslonghorn5 in "Intelligence Suggests Pro-Ukrainian Group Sabotaged Pipelines"

texaslonghorn5 — Tue, 07 Mar 2023 17:29:49 +0000

> U.S. officials declined to disclose the nature of the intelligence, how it was obtained or any details of the strength of the evidence it contains. They have said that there are no firm conclusions about it, leaving open the possibility that the operation might have been conducted off the books by a proxy force with connections to the Ukrainian government or its security services.

There's very little of substance in this article, since it doesn't disclose the intelligence or the officials making the judgement. So it comes across as "x refused to comment, y refused to comment, but we wanted to break the story first so trust me bro"

> rising to the non-associative power indices ... in the last two decades has been analyzed and does not have a quantum polynomial algorithm that solves it. The problem is called Exponential Congruences Problem.

The author uses similar wording a couple times and it is a little ambiguous? Does "does not have" mean a superpolynomial quantum lower bound has been discovered for this algorithm (or is there a reduction to some other important conjectured complexity theorem)? Or is it just that a polynomial algorithm has not been discovered yet?

no because k is an argument and you have to pre-write k nested loops

> The year-long human trials for Synchron's BCI system have been peer-reviewed by a neuroscience medical journal in Australia(opens in new tab), where the study found the technology safe and signal quality didn't degrade for its Australian patients. The study also concludes that "the favorable safety profile could promote wider and more rapid translation of BCI to people with paralysis." We'll give it about another year before someone's running Doom on it.

New comment by texaslonghorn5 in "The Absurdity of Income Tax"

The truly wealthy are making much of their money passively, income tax isn't really something they think about. The government would need to increase the estate and capital gains taxes to actually balance/unburden things.

Regardless, I found the anecdotes entertaining.

this isn't a materials science article, as it turns out.

if you've already read your three free articles, https://archive.is/VcIcJ

thought it was an interesting perspective, though it's a bit naive or maybe idealistic and it glosses over a lot of the negative harms of some technologies (and factors, economic and otherwise, that motivate these kinds of technologies).

Considering that Scott works in theoretical quantum complexity theory, I highly doubt that he reviewed this experimental quantum error correction paper.

there's a lot to unpack in this comment but I'll pick off one point and maybe others will contest the rest

> Only a very small minority of people have careers or relationships worth emulating, and they should be setting examples for everyone else to aspire to.

Of those that have relationships worth emulating I doubt they are parasocially broadcasting it for the world to see. To the contrary, most of these images that you see on social media are heavily curated and manicured and don't really reflect reality.

so based on empirical observations I am sure there are a number of people who are making barely enough to support the child care cost quoted in the post I quoted. maybe I misinterpreted the post I responded to

$540/40hrs = $13.5/hr. Any number of jobs pay this little.

Google searching "Bard Arendt" yields "Hannah Arendt Center for Politics and Humanities at Bard College" so likely this pdf is generated or hosted by this center's account.
