ahazred8ta··on AI refutes 30-year-old mathematical assumption in computer science
Superpolynomial subexponential runtimes. / Even though in practice it would take you several lifetimes, / If you ran it long enough you'd always find those two primes. / Superpolynomial subexponential runtimes -- Eric Hughes (2000)

As they said in "Yes, Minister": "under consideration" means we've lost the file; "under active consideration" means we're trying to find it.

ahazred8ta··on Ask HN: Are signed URL previews feasible?
Signed webpage schemes have been around since the 1990s. https://duckduckgo.com/?q=pgp-signed+webpages&ia=web

Recording the TLS session doesn't work. The content is only authenticated with a symmetric session key. The content is not signed by the server's private key. Anyone can use the same session key to forge a different session with a modified webpage and new auth tags. The hash of the webpage is not signed by the private key. This is intentional. The protocol is not intended to bind the content to the private key.

In 2016, Clinton spent $576.4 million and Trump spent $332.4 million. In 2024, total spending including PACs was $1.6B for Biden/Harris and $1.1B for Trump. There was less money behind Trump both times.
ahazred8ta··on How machines learned precision
Ditto the makers of scientific instruments, and the manufacturers of moveable type. The printer's ligne was 1/6 of a continental inch, and the typographic pointe was 1/12 of a ligne.
ahazred8ta··on Kevin Kelly – The Influence of Science Fiction on Science
After it was discovered that radiation was the result of atoms randomly decaying over long periods of time, there was speculation about making them release all their energy at once. There were sci-fi stories in the 'teens and 20s about discovering a ray that could be shined on radioactive material to make it go foof. There was no concept of neutrons, critical mass, or slamming hemispheres together. The idea was that the bomb residue would be nonradioactive because it all decayed.
ahazred8ta··on How machines learned precision
Interesting that many of the early steam mills used a steam engine to pump water into a water tower, which then drove a conventional water wheel to power the millworks.
ahazred8ta··on How machines learned precision
Armchair metrologist here. Did metalworkers back then use 16ths, or 12ths and 24ths? I'm familiar with the use of 1/12th lines ''' and multiples of 1/144th points ''''.
ahazred8ta··on Treachery in the Rodin Museum 3D scan verdict
From the 1500s, there were large numbers of Irish mercenaries called 'Wild Geese' who served in continental armies, and there have been communities of ethnic Irish people there for centuries. In particular a large number of Jacobite refugee families settled in Normandy after 1691. https://en.wikipedia.org/wiki/Flight_of_the_Wild_Geese
ahazred8ta··on Treachery in the Rodin Museum 3D scan verdict
It sounds like there were two different factions within the museum: one which intended to scan all the works and put 2D and 3D scans and models online, and one which did not want any scans to be released. The grants were obtained by Group A; Group B seems to have veto power.

ahazred8ta··on NASA asked several former SR-71A staffers to help secret restart
At several points in time, the Pentagon proposed mothballing the SR-71 and relying on sat-recon. And each time, the aircraft-recon imagery people screamed bloody murder and insisted they needed the aircraft imagery. And then one day the Pentagon announced that they were shutting down the SR-71 ... ... and there was a thundering silence from the aircraft-recon intel people. Almost as though there was already a replacement for the SR-71 but nobody could talk about it.
ahazred8ta··on The last time my family was replaced by technology
In the late 1800s there was a cottage industry of mechanics and ironmongers selling and repairing small steam and kerosene engines used by rural mills and farms. There were horse drawn steam threshing machines. Bicycle repair shops sprang up. The Wright brothers got into the bicycle business before horseless carriages. There were many intermediate tech skills that led up to working on motorcars.

ahazred8ta··on In an $80 Motel Room, a Discovery to Shed Light on the Origins of Life
Paper from last fall https://onlinelibrary.wiley.com/doi/full/10.1111/jeu.70040

They've known about the Paulinella genus for several decades, but they're always glad to discover a new species. This genus acquired a photosynthetic symbiont "only" 100 million years ago, and it's only partway through the process of losing its genes. It's a snapshot of the evolutionary process.

TBH, this has almost nothing to do with the origins of life.

ahazred8ta··on Newly Discovered Neo Asteroid 2026 SA8 Close but Safe Approach
The nearest approach is 0.988x Lunar Distance (379,868 km), 60 Earth radii out. The size is very roughly 6.7 meters, 22 feet. If it hit the atmosphere, the airburst would be about 5 kilotons. Airbursts like that happen every few years. https://en.wikipedia.org/wiki/Meteor_air_burst#After_1900

ahazred8ta··on My German Exit Tax: 13 Tax Advisors, 1.5 Years, 18.7k€ to leave the country
They wanted him to pay almost six years worth of his normal post-tax income. Did you have to pay six years worth of income? It took him a lot of work to get it down to 'only' 18.7k€.

This ranks right up there with the author who wrote a children's book about a village where they had to turn over 102% of the potatoes they grew. https://en.wikipedia.org/wiki/Pomperipossa_in_Monismania
