Commentrebar? (Score 2)33

Was hoping for a bit more detail than the article gave. Concrete is great and all but how do they make it earthquake resistant? Or survive broad face hurricane winds on a 20' tall flat wall? Can they put rebar in the walls?

If Linus is right, then the kernel should treat all filenames as a stream of bytes. Good idea? Not really.

There's really no other sane way to do it. Even Apple has come around to this as this is the exact thing Apple's APFS does. Filenames are simply bytes, assumed to be (and forced to be) valid UTF-8. Of course it's complicated by the fact that there are different ways of normalizing UTF-8, so you can get a situation where you copy files from a mac to Linux and you might see two identically-named files where one used NFC and other used NFD normalization. Unicode is kind of messy that way. Though folks argue that Apple chose the wrong normalization scheme.

The moon, like all solid bodies, has a surface rich in oxides.

Honestly, this to me isn't as interesting with respect to the moon as it is with respect to Venus. Venus is very hydrogen deficient. If you could dramatically up its hydrogen capture rate (e.g. magnetic lensing) and in a way that would greatly exceed the loss rate (normally we think of the solar wind as a loss mechanism), it would have a wide range of effects that would make it more earthlike. In particular, you'd get the Bosch reaction, where H2 and CO2 react to form water and graphite. Venus's surface is active (both volcanism, and while it has no subduction, it has microplates that jostle up against each other), so over geological timescales, surface carbon will be sequestered. So you're lowering the pressure, lowering the temperature, raising the water, and lowering the acidity. Also, if the water content in the crust rises over geological timescales, it becomes more ductile, so potentially - after immense timescales - you might *possibly* start/restart plate tectonics

None of this would be at all on human timescales, but it's interesting to ponder whether Venus's conversion to a hellscape could be slowly reersed.

this.

I only reluctantly gave up atavist for the weaker search but broader index of google.

But I've tried, off and on for several years, to use non-google search engines.

I think that that 80% is about right on usable results from bing/ddg -- but it's unusual day that I don't need to go to google at least once. For some searches, I don't even bother and go straight there.

what finally got me to change my default away from google was the effort of typing "-video:" (which also excludes ai) on every search.

in related news, still waiting for an orbital strike on the YouTube servers, but in vain. Really, how can you make a vive minute "video" on the firing order of an eight cylinder engine (the numerals 1-8 in some order or another) ?
