hyperthesis··on I've acquired a new superpower
A parallel processor is you!
hyperthesis··on Fermat's Last Theorem – how it’s going
There'a a story that when someone wrote up a famous mathematician's work (Euler?), he found many errors, some quite serious. But all the theorems were true anyway.

Sounds like Tao's third stage, of informed intuition.

hyperthesis··on Unique killer whale pod may have acquired special skills to hunt whale sharks
Consider whaling, by killer apes.
hyperthesis··on Everyone is capable of, and can benefit from, mathematical thinking
This beats TFA. Interesting relation between cumulativeness and distribution ("Yule process"). But how does this explain variation is how quickly children pick up maths - would you argue it's due to prior exposure e.g. parental tutoring?

Any comments on the "10x programmer"?

hyperthesis··on Ask HN: Axiomatic algebra, like ch 1 Spivak's Calculus?
Being more precise: I like Spivak not defining addition, multiplication or number. I just want the other steps explicit, like equality transitivity, enough to implement it (for a computer without "mathematical maturity".)

I feel I already know what's needed - but I didn't catch the 0.a=0 omission at first, and there's surely others I'm still missing... Part of the problem is I have too much implicit knowledge.

hyperthesis··on Ask HN: Axiomatic algebra, like ch 1 Spivak's Calculus?
Thanks, I'll take a look at those late chapters.

The algebra is my main interest, that happens to be in a calculus text.

0a = 0 is proven later in ch 1, it's just the ordering.

By "something I could code", I mean implementimg these properties (more like writing a proof assistant).

hyperthesis··on Applied Mathematical Programming
TBF Binet's formula is astonishing
hyperthesis··on Writing a book in the age of open source
Knuthing it.
hyperthesis··on UE5 Nanite in WebGPU
This is like when Joel said git stores diffs.
hyperthesis··on Scientists discover a new hormone that can build strong bones in mice
Read of a study years ago that had postmenopausal wpmen do weight training - giving a dramatic 40% increase in bone density in 6 weeks IIRC the details.

It's not that frail people need to be inactive, but that inactivity causes frailty.

hyperthesis··on How I've Learned to Live with a Nonexistent Working Memory
Can't read without an account.

Also "working memory" is short-term storage, like registers, the details of what you're thinking about right now. Not memory of past events, like your wedding day.

hyperthesis··on The Right Kind of Stubborn
"Giving the world a solution" vs. "showing the world how flawlessly smart they are" reminds me of being "visited" by a genius (muse, inspiration). You now have the gift to share, but it doesn't show you're a genius.
hyperthesis··on Face of ancient Australian 'giga-goose' revealed after fossil skull found
The climate change created land bridges. https://xkcd.com/552
hyperthesis··on I found a 55 year old bug in the first Lunar Lander game
Though famous as the first lunar lander game, the impressive part was the specific numerical techniques used.
hyperthesis··on POV-Ray – The Persistence of Vision Raytracer (2021)
Also the high-quality amateur scientist webpages. e.g. measurements on radiation heat loss to the sky when camping.

OTOH... we now have sci-hub.se with high-quality professional scientist papers.

hyperthesis··on Most life on Earth is dormant, after pulling an 'emergency brake'
Don't they (traditionally) also have a much higher meat intake than average, which supplies vitamin D?
hyperthesis··on How actors remember their lines
I was curious: they all have two-syllable names except for Doc (leader).
hyperthesis··on AlphaFold 3 predicts the structure and interactions of life's molecules
Engineering often precedes Science. It's just more data.
hyperthesis··on Simplicity is an advantage but sadly complexity sells better (2022)
Complexity signals innovation: an invention that is merely a "workshop improvement" won't get patented. Complexity signals non-obviousness.

Too easy -> easily copied -> and no long-term competitive advantgage. Complexity signals hard.

hyperthesis··on Simplicity is an advantage but sadly complexity sells better (2022)
"There's no bragging rights to your software, because it's too simple to use", a developer criticized my product. This reduced its viral spread, though managers liked it.
hyperthesis··on Simplicity is an advantage but sadly complexity sells better (2022)
The solution to a problem can be simple.

But now we want other things. e.g. car=transport, then: speed, efficiency, style, non-polluting, safety, price, a/c, touchscreens, self-driving etc.

The boundless complexity of human desire.

oblig. perverse incentive https://www.folklore.org/Negative_2000_Lines_Of_Code.html
hyperthesis··on In Praise of Idleness (1932)
"[A]ll the low hanging fruit have been plucked" from these trees.

In a complex, highly multi-dimensional space, yes, there's always a hill to incrementally climb. There are other hills.

Incrementalism gets you necessary data; but not necessarily insight.

EDIT Of course, following up an idea is work.

hyperthesis··on Cardio fitness is a strong, consistent predictor of morbidity and mortality
Can anyone give a sense of how much fitter 3.5 mL/kg/min is, in practical terms? e.g. distance cycled/how out of breath?

> For every 1-MET (3.5 mL/kg/min) higher level of CRF, we identified substantial reductions in the risk of all-cause, CVD and cancer mortality. We also identified significant reductions in the risk of incident hypertension, heart failure, stroke, atrial fibrillation and type 2 diabetes per higher MET.

> For most, a 1-MET higher level of CRF is attainable through a regular aerobic exercise programme. For example, in a large population-based observational study of over 90 000 participants, nearly 30% were able to increase their CRF by 1-MET (median follow-up was 6.3 years) without intervention.

hyperthesis··on The Snapdragon 855's iGPU
There's still real-time ray-tracing.

Cosmetic physics can eat up more, but as a gameplay mechanic, user interaction with realistic physics are too unpredictable (beyond a gimmick). Of course, we could then get actual computer sports.

hyperthesis··on New Foundations is consistent – a difficult mathematical proof proved using Lean
It will eventually become as chess is now: AI will check and evaluate human translation to and from English.
hyperthesis··on Orwell’s Escape
There's an automatic conformity within us, which is useful for communication, learning, trade, custom and law. e.g. It's helpful that we try to use the same words for the same things.

But we can't think outside our frameworks with this conformity engaged. Hence, the need for solitude.

I think the greater problem of a "person on business from Porlock" (https://wikipedia.org/wiki/Person_on_business_from_Porlock) was not the interruption itself, but that it engaged Coleridge automatic conformity... and so, without moorings, his imagined unreality drifted away like a dream on waking.

I must add that this is a higher human intellectual need - but we are also gregarious by deep mammalian nature, and if isolated, will invent and converse with imaged persons.

hyperthesis··on Structuralism as a Philosophy of Mathematics
Well, there's the fundamental theorem of arithmetic, that there is exactly one composition of prime factors for every natural number (excluding ordering). https://wikipedia.org/wiki/Fundamental_theorem_of_arithmetic
hyperthesis··on A Theory of Composing Protocols (2023)
Thanks for your guidance! I now see they're (now-obviously!) things like TCP and http. I had missed their informal definition:

> Here we use the term protocol to denote a specification of the interaction patterns between different system components. [...] To give a more concrete intuition, an informal specification of a protocol for an e-banking system may be as follows: The banking server repeatedly offers a menu with three options: (1) request a banking statement, which is sent back by the server, (2) request a payment, after which the client will send payment data, or (3) terminate the session.

I would say it's like how you use an API.

hyperthesis··on A Theory of Composing Protocols (2023)
What exactly is a "protocol"?

I skimmed the pdf for a definition, but it seems to only give examples, then jump directly to defining compositions.
