Truth and kindness are the most important things
Nah that wouldn't happen. (Pumpkin is obviously better, and this objective fact is impossible to sanely argue against).

I legitimately thought this was some kind of advanced humor, but yeah no this tee unfortunately is just AI slop.

Banned books definitionally challenge the mainstream, so it greatly undercuts the point that the shirt promotes them by mixing the mainstream into a slurry and selling it as original!

This image is definitely fake. Look at the lighting on the clouds vs. mountains for example; it's in completely opposite directions.

Please be careful reposting secondhand images with secondhand captions. Most beautiful things you see on the internet today are blatant forgeries, to everyone's loss.

We split the atom,
And kill hundreds of thousands.

We split the atom,
And threaten billions more.

We split the atom,
And power our cities.

The fossil lobby smiles.

We split the atom,
And "green" groups scream for coal.

We forget how to split the atom.

And destruction's peril
Becomes certainty.

What kind of five-year-old writes in flawless common meter (four lines of alternating iambic tetrameter and iambic trimeter)?

The cool, colorful, fashionable Autumn, the holiday-filled, sparkling peace of Winter, and the new life of early Spring.

"Reverse seasonal affective disorder" is a real thing, but I've never understood how *we* are supposedly the weird ones!

Me, I am aligned to the rain.

Anonymous structs are "not supported", but in practice every C++ compiler supports them (in particular, Clang, GCC, and MSVC all do), so they can actually be freely used.

Note for any members' constructors you just initialize directly, as if the anonymous struct wasn't wrapping them.

(1) It sucks because it is ad-driven, and therefore Google has a perverse incentive to make your results worse, ensuring you spend more time looking at ads.

The tech people rejoice in what *can* be built.

The academics despair in what *has* been built.

This is actually an AO render. Originally, I was going to make it a render with glass material and an envmap, but the ray depth explodes. It also turns out all those interactions efficiently attenuate paths, so the right answer for glass is a mostly black image anyway. AO brings out more detail!
