  • I have one, it’s been great.

    That said, “exactly what the problem is” isn’t always the same as telling you the solution. I had a “misfire on cyl #3” error or something like that, which can be a number of things. Replacing all the coils and plugs myself was probably still cheaper than taking it to the shop though!





  • Except on the Linux systems I’ve used, when I ask it to shut down, it shuts down no matter what. Windows and macOS let programs stop the shutdown process indefinitely (when shutdown/reboot are invoked the usual way).

    I think that’s what the meme is trying to get at.







  • Aluminum foil is very common in physics labs. And a main use for it is “baking”! To get ultra high vacuum (UHV)* you generally need to “bake out” your chamber while you pump down. Foil is used same as with baking food — keep the heat in and evenly distributed on the chamber.

    Sadly, it’s usually not food grade aluminum foil, as that can contain oils, and oils and vacuum are generally a big no-no.

    *Just how good is UHV? Roughly: I live in San Francisco, which is ~7 miles by ~7 miles (~11km). Imagine you raise that by another 7 miles to make a cube. Now, evacuate every last molecule of gas out of it. Now take a family sedan’s trunk, fill it with 1 atmosphere of gas, and release that into the 7 mile cube. That’s roughly UHV pressure.
