  • Based on videos from one of the major lava-themed entertainment venues who has been posting updates for two months, the “barriers” for Grindavik were barely started, with work only beginning some time after January 4th or 5th. The primary focus of the public work was in building the barriers to protect the regional power plant to the east of the fissures (and hot springs resort area just east and north the power plant). IIRC, those barriers took a month to construct.

    The subsurface dam/inclusion runs pretty much directly under Grindavik, so if an active eruption opens along the southern edge of the magma inclusion there will be no way to prevent damage to those houses adjacent.

    Disc: I’m neither a seismologist nor a volcanologist, but I’ve seen Journey to the Center of the Earth. Oh, and I was in Grindavik in October.



  • Yeah, that’s just a shitty (or out of spec) time base. My Seiko watch gains 1-2 minutes a day, but it’s completely mechanical so it depends on temperature and winding/mechanism tension for accuracy. There are electronic timing circuits which are resistance and capacity based, and as the resistance and capacitance of the system drift (time/age and temperature) they also drift. A crystal, made to vibrate at high frequency (piezoelectrically, iirc), will provide a much more stable time base and be accurate to seconds over many days’ time.

    Interesting aside - time keeping is how ships at sea used to determine where they were in the ocean. Latitude can be found from the stars, but longitude can’t so it needs a time reference standard. The book, Longitude tells the story of the search and the competing methods for determining location prior to the invention of crystal/electronic time bases and modern GPS. I won’t say that the storytelling is particularly gripping, but the actual path to discovery is fascinating.


  • That’s probably just fluctuations in the line frequency and the method for keeping time varying between the two (one might use a crystal that drifts). Being on the “wrong” frequency will have it shift by hours every day. I had a (US/60Hz origin) microwave in my apartment in Bonaire (50Hz) last year that never seemed to have the right time, and when I did the math I realized it was the frequency - it was behind by ~4 extra hours every day (50/60 x 24 hours).






  • Marketing: We need to defend this - what’s something people are really excited about?

    Engineer: Stainless steel; you can’t make a good stainless without nickel

    Salesman: Oooh - I know! How about nickels? Everybody loves nickels and their worth 5 cents each!

    Engineer:

    Marketing:

    Intern: You know, they use nickel in battery packs for electric cars

    Marketing: Oh, right - everybody likes electric cars. Green and vroom-vroom, I love it!

    Engineer: You know that electric cars don’t go vroom-vroom, right?

    Marketing: I’m going with electric cars, it’s a feel-good use people will get behind.


  • I mean, we sort of set up this fuck-fest despite Britain telling us it was a bad idea. But we were the Victors of the World™ so clearly we knew what we were doing (clears throat). Kind of like our useless embargo of Cuba, we made a decision and we’re sticking with it, no matter how stupid or counterproductive it is, and there’s a very vocal portion of the electorate which supports the move (mostly out of spite, which makes them that much more intractable).

    Is the current war terrible? Sure. Nobody should be killing civilians or taking the hostage. Is the plight of the Palestinians real? Yeah, it is. Israel has been an absolute menace, because they can.



  • Maybe stupid is the wrong word? Willfully, negligently, and/or belligerently ignorant might be more accurate, I guess. These people get pretty angry when told they can’t build on “their land” because it s uninsurable and it is within the (statistical) flood plane. These are the same people you see crying on TV and angry at the government for not paying to rebuild their house, or for letting them build there at all, after a flood. They conveniently forget how they were told that it would flood and they intentionally ignored the warnings. I don’t know; in my book that’s pretty stupid.


  • “the country’s flood zones — areas that are deliberately flooded to absorb excess water — were built. But such areas are no longer as sparsely populated as they once were. Local governments have allowed towns in designated flood zones to grow, despite regulations meant to control the number of residents living there.”

    "“Is it the government’s fault or is it the people’s fault for moving back to these places?” said Wang Weiluo, an engineer and expert on China’s water system who is based in Germany. “It’s the government’s. All those people were given approvals to build their homes there. They’re the government’s rules and they didn’t enforce them.”

    Yeah, so, I happen to work in this field (or adjacent to it) in the US. At least here, everybody knows where the flood zones are - published maps, disclosures when you buy property, disclosures/regulations when you build. And you know what? The dumb motherfuckers I work for will do everything they can to skirt the regulations because they haven’t seen in flood in a long time, and the government is just over-regulating. And in the rural counties where there is little to no regulation enforcement, they just build there without permits - or even with permits that have been issued without due diligence on the part of the building official.

    I have no doubt that there are a bunch of stupid fucking hicks in China, and stupid fucking hick government officials, and greedy fucking land sellers and builders who have the same attitude. I feel bad for the people who got flooded out and lost everything, because that’s a terrible fate - especially if you didn’t realize what you bought. But this is the result of human stupidity.

    Life is hard. It’s even harder when you’re stupid.



  • If you’re not writing your own software for the phone, and you don’t need access to the raw sensor data, there’s likely an equal app for iPhone now. I was in the same boat for a while - needing things that only android offered. I switched to iPhone in '19 I think, and I’ve found replacement apps for everything except detailed wifi scanning. Also, the apps I used on android which offered direct GPS tracking would show how many satellites and nominal locations are just binary - you have signal or you don’t. That’s frustrating when you’re at the edge of signal and trying to get a lock.

    I can see how it would be a deal breaker if you need a specific app for work. I can’t switch to mac as several of my (multi-thousand dollar) analysis programs are windows only, and if an update breaks something or there’s an incompatibility, it costs me $2k/day to troubleshoot.
