  • You could say the same for a finite element model. A junior engineer with just 4 years of training can solve, explicitly, the deflection at the center of a slender, simple-simple beam of prismatic section and produce an exact (if slightly incorrect) answer. Building a FEM of the same can solve the problem and take longer (to make the model) with similar accuracy, both of which are good enough for design work.

    Only a fool wouldn’t have a FEM around though, as it can solve problem that would take centuries for a human to solve. They may as well make a cartoon with the child digging a 3” hole in beach sand and then showing a backhoe making a jagged edged hole of the same size.








  • Reminder - gas prices cannot be hiked by suppliers because they don’t own the gas. Petroleum products are bought and sold on commodity markets before they’re ever refined or even removed from the ground. These “futures” are bought and sold and the price at the pump is related to the current price to purchase the product from the commodity brokers, plus transportation and local markup.

    There are legitimate uses for futures contracts, but much of it is just gambling and capitalistic opportunism.




  • That’s sort of how I do mine. I put all my data onto dropbox/onedrive. I’ve got a $100 HP USFF hooked up in my office that is a 100% online mirror for those cloud accounts, and it backs up to an 8TB external each week. I rotate that drive with a spare each month (give or take), putting the “offline” one in a firesafe. It means I have a live copy (my pc), a cloud copy (OD/DB), a second hot copy (USFF PC), a near-line backup no more than 7 days old that isn’t “live” and a cold storage copy that is no more than a month old (aka less than Apple’s deleted-pictures and Dropbox’s previous version storage time). It cost me two external drives and the mini-pc. And if all those fail I’ll probably be roaming the radioactive wasteland looking for food and losing that data won’t matter.

    Oh, and that little box also runs a small FTP server and my Torrents for my Linux distro collection.
