[Sorry if this joke is too lame, but...]
A pedophile, a traitor, a thief, a fraudster, a wife beater, a failed businessman, a draft dodger, a tax evader, a semi-literate moron, a felon, a mob boss, a rapist, an insurrectionist, a mass murderer, a tacky decorator, a golf cheater, and a senile man walk into a bar. Says the bartender, "And what will it be for you today, Mr. Trump?"

Ray Bradbury has a story with this theme. IIRC, written in the 1950, and set in the very near (then) future after mankind is wiped out by a global nuclear war.

OBJ is a file format for describing 3D shapes of things, e. g. for 3D printing. A .obj file contains data lines that define coordinates of points, corners and colors of polygons, curved surfaces, etc.
Today I learned that version 3.0 of the OBJ format may include lines like this:
csh <command>
Executes the requested UNIX <command>.
Sigh. Have we learned nothing since the Morris Internet Worm?

What is the proper general term for someone who is bent on imposing their *religious* beliefs on those who do not share them? Like the Taliban, Iran's Revolutionary Guard, the Spanish Conquistadores, ...

Never have I ever understood the rules of American football.
(I barely learned /some/ of the rules of baseball when my kids were going through the Baseball With The Parents Watching rite of passage, but promptly forgot them as soon as that brief period was over.)

Does not look like Trump or Sanders. Biden, perhaps?

Back in high school I had an exceptionally lazy teacher who let the students grade their own exams.
When did the FAA start delegating the certification to Boeing?

Don't trust the Wikipedia article. The definition of "mole" was changed in 2010 and some editors apparently haven't realized that yet. Now the Avogadro number is an exact number, essentially adimensional like pi or 360 degrees per turn. No longer a "physical constant".

/Chernobyl/ was good, it deserves a sequel or two.
