I wonder what percentage of Google Lens is used for legitimate purposes versus students using it to do their math homework for them.

I know that Linux Mint has some older, stable packages for its software that aren't bleeding edge. However, is there any way to force it to update LibreOffice to the latest version? I suppose that means adding a repository, but I am unsure which one. #LinuxMint #LibreOffice

Yeah, I totally still need that single-core intel machine that I was using as an HTPC back in 2009. I'll plug it back up and use it any day now!

...or just let it sit by my desk holding up other obsolete machines I've built/used/hoarded since then.

Going to War with Iran is wrong. It won't matter what justifications they use or which turn out to be true. We've seen this script before. We will gain nothing, and will have introduced needless suffering and death into the world. Congress needs to regain its war authority or it is lost for good. #USA #Iran #IranWar #NoWarWithIran

So, I teach high school math and we use numworks graphing calculators. They've been excellent! However, I recently ran across an issue that shows you can't always trust what your calculator says.

Suppose you want to take the cube root of negative 230. You should get approximately -6.127. It is perfectly fine to take the cube root of a negative number and get a real result. However, if the calculator is in Complex/Cartesian mode for displaying complex numbers, you get approximately 3.063+0.306i. Simply moving the negative sign outside of the radical sign (again, this is just fine to do in high school), you get the correct answer as shown below.

I wonder what causes this?
