I think what happened here is that something went wrong and messed up the permissions of some of the users files. MS help suggested that he login as an administrator and reatore the intended permissions.

I don’t work with Windows boxes, but see a similar situation come up often enough on Linux boxes. Typically, the cause is that the user elevated to root (e.g. the administrator account) and did something that probably should have been done from their normal account. Now, root owns some user files and things are a big mess until you go back to root and restore the permissions.

It use to be that this type of thing was not an issue on single user machines, because the one user had full privileges. The industry has since settled on a model of a single user nachine where the user typically has limited privileges, but can elevate when needed. This protects against a lot of ways a user can accidentally destroy their system.

Having said that, my understanding of Windows is that in a typical single user setup, you can elevate a single program to admin privileges by right clicking and selecting “run as administrator”, so the advice to login as an administrator may not have been nessasary.

You joke, but after cosmonaut Alexi Leonov complained about the possibility of a bear attack, the TP-82 ahotgun was standard issue on Russian spacecraft for decades.

There are still a lot of rather arbitrary decisions to make.

Is 4/pi inside or outside of the summation?

Is it (-1)^n+1 or (-1)^n with an additional negative sign in any of the other natural locations for it.

Is the e term outside of the fraction with a negative exponent, or part of the denominator.

Do you start with n=0 or n=1 (and adjust the terms inside the summation accordingly)

Did they expand (2n+1)^2?

As a kid I attended a Jewish day school, and we had a year long class on European-Jewish history through the Holocaust.

The post screenshotted (allegedly from the AGA) reads almost like it came right out of that era as a piece of anti-semetic propoganda.

Seriously. Weather the post was actually from the AGA, or an anti-semetic propogandist, it is 100% blood libel, and should treated as such.
