“Stunning victory” means the political insiders were convinced the progressive candidate would win—and were terrified at the prospect.

Had a wasp fly up one leg of my trousers. Stung multiple times. Apparently I did a funny dance too.

Every time I read glowing stories about how effective drones are on the battlefield, I can’t help but think that the majority of their use in the future will be for suppressing civilian populations.

Maddie is tired of shouting into the void and has decided to try napping in it instead

“We’re teaching math wrong” (part N/???)
When you were introduced to sine, cosine, and tangent, I’m going to bet you were introduced to them in terms of triangles. Maybe you remember learning “SOH-CAH-TOA” to keep it all straight. Then maybe much later in your curriculum they showed you the unit circle, radian measure, and had you memorize a bunch of facts about signs and quadrants, etc.
I’m here to tell you that your confusion was natural because they taught you the subject exactly backwards. Trigonometry proceeds from the circle first! There’s a reason it’s called the “tangent” kids—it’s the slope of the tangent line that touches the unit circle at whatever point bounds the arc you’ve chosen.
Once you get the Pythagorean theorem under your belt, we can explain the basic trig functions to you on the unit circle in a way that makes sense both visually and algebraically (whatever learning style you prefer).
Yet another example where math curricula are apparently designed by people who don’t understand math—historically or otherwise.

Here’s the way this is going to go down. Once people become accustomed to the current shoddy and easily bypassed age verification systems, and astroturf movement will start saying, “Egads! These systems are easily bypassed! We must PROTECT THE CHILDREN!” And we will move from badly blocking content to completely censoring it. These people are playing a longer game.

Don’t let other people stomp on your happiness. If it’s not hurting anybody, do the things that make you happy, even when others belittle them or say they’re uncool.
Being true to yourself is cool. Having a passion is cool. Finding joy is cool.

The correct crowd response during the chorus of “Sweet Caroline” is?

If you can pick it up, so can the wind. And the wind can throw it a lot harder and a lot farther than you ever could. All loose objects should be cleaned up and stored inside well before the storm approaches.
Put up your storm shutters, barricades, and/or sandbags now, today. Milton will apparently be pushing lots of rain ahead of it and conditions tomorrow may be difficult.
You will lose power. Try to keep your electronics plugged in as much as possible, so that when power does go out you will be fully charged. Make sure all your backup power supplies are fully charged. Test your generator/battery/solar fail over. Generator fuel supply secure?
Filling a bathtub with water is not a bad idea. If water does go out, you have an extra supply for flushing toilets or drinking (after boiling).
How am I going to boil water if the power is out? Too late to get one now, but a propane stove is helpful to have in your hurricane kit (along with a supply of propane). Once it is safe outside, you can boil water and have hot meals.

The baby is Bowman who had transcended into a higher existence as the star child. Basically he’s an infant god looking down at Earth from on high.
