  • The security level should be the user’s choice. Maybe I don’t care if my neopets account is hacked. Maybe the 2fa offered actually decreases security, like the SMS 2FA required by my 401k account that can be used as the sole recovery factor, bypassing the password. Maybe I’m accessing from a system configuration that makes 2fa really annoying, like a build system running inside a fresh VM on every run.

    The service doesn’t have the context necessary to know when 2FA is warranted.






  • There’s multiple things you’re mixing up here. There’s the “up” in the global coordinate reference frame. This could be based on the local system, though that makes entering and exiting the system a tiny bit more difficult. More likely it’d be based on galactic coordinates.

    There’s also the ship reference frame in the comic. This probably won’t be oriented towards the global coordinate system. It’ll be oriented towards whatever the engines, sensors, and gravity need. Because the ships will all be in orbit, their orientations will probably be changing constantly relative to other ships and the global reference frame. There’s no reason to orient in a single direction and lots of reasons not to (it wastes energy, points your sensors away from the things you want to see, etc).

    Just did a quick eBay check. The cheapest 350hp ICE I could find was a rebuilt $3,000 Chevy engine. A new one is more like $6-8k. An equally powerful, brand new Siemens motor was $1,500.

    This makes sense when you think about it though. An electric motor is basically just steel with a bunch of coiled wire with some control electronics. An ICE is hundreds of pounds of precision cast and machined metal. The cost driver in electric vehicles is not the motor, it’s the batteries.





  • Genesis is pretty clear that Egypt came after the flood. Noah had sons with him. One of them, Ham fathered Africans. Noah’s grandson Mizraim was the father of all Egyptians.

    Some early Christians reconciled that with the obvious age of the pyramids by guessing that the pyramids predated the flood and modern Egyptians were simply a new population, but no one’s seriously argued that in literal millennia.



  • I’m not the one who posted the initial response, I’m just explaining what they meant.

    Also, this isn’t intended to be dismissive or insulting because I recognize that everyone comes from different backgrounds and experiences, but it’s pretty widely known that different crops have different labor costs. Everyday is a chance to learn something new though. Here’s a quick overview from UC Davis on the subject.

    I’d also recommend the book Fresh Fruit, Broken Bodies if you want a more personal, on-the-ground understanding of (some of) the human costs of agriculture. Understand that no book can cover everything though and there’s much worse costs than anything it covers.

    None of this human cost is inherently related to concepts like monocropping either. Rather, they’re related to the economic and political context agriculture exists in, especially how those impact current mechanisation capabilities. Harvesting things like cereals is so efficient in large part because of the huge demand from livestock agriculture for cheap feedstock to justify the development/purchase of things like combine harvesters.

    Some crops aren’t heavily mechanized though, and modern agriculture hires cheap laborers instead. These tend to be the expensive things at the grocery store for fairly obvious reasons, but not always. If you’re buying Spanish produce in Europe (e.g. bell peppers), there’s a reasonable chance it was harvested by migrant workers working under inhumane conditions in a greenhouse. Things like coconuts tend to have slavery and animal cruelty in their supply chains and that’s the basis for a good chunk of cuisine in South Asia.

    Another way to directly tie specific crops to their human costs is to look at the daily dead body reports by US border patrol. They tend to spike a couple weeks before/after certain crop harvests. Strawberries and tomatoes show up particularly strongly in this kind of analysis, which is why I mentioned them. You can also see the spikes from things like grapes, lettuce and beans.
