Cloaking devices -- it's not just 'Star Trek' anymore
During the 175th Meeting of the Acoustical Society of America, being held May 7-11, 2018, in Minneapolis, Minnesota, [Amanda D.] Hanford will describe the physics behind an underwater acoustic shield designed in her lab.
Hanford and her team set out to engineer a metamaterial that can allow the sound waves to bend around the object as if it were not there. Metamaterials commonly exhibit extraordinary properties not found in nature, like negative density. To work, the unit cell -- the smallest component of the metamaterial -- must be smaller than the acoustic wavelength in the study.
[...] To date, most acoustic metamaterials have been designed to deflect sound waves in air. Hanford decided to take this work one step further and accept the scientific challenge of trying the same feat underwater. Acoustic cloaking underwater is more complicated because water is denser and less compressible than air. These factors limit engineering options.

"Bend over!"
"I don't wanna!"
"Bend over!!!"
The man screamed at the child at the top of his lungs. Since the child would not comply, the man, Emmerson, used his superior might to force the child to bend over and then jammed his penis into the boy's anus.The man was squeezing the child's neck from behind while also slamming his genitals deep inside his rectum. Describing the man's treatment of the little boy as 'vicious' would be a gross understatement. The child screamed and cried, but the man's treatment of the boy only became more violent. And it was all the kid's fault.
Yes. If the child had only instantly acceded to the man's command, the normally-kind adult would not have been as angry or violent. Thus, this was the boy's doing, and he had to take responsibility for his foolish actions. And take responsibility he shall!
The man's level of righteous fury increased exponentially by the second. "How dare you not obey me!" the man screeched. As the man's fury increased, so too did the amount of force he dispensed. This eventually resulted in a sickening snap; the boy's motion had at last come to an end.
But the man was furious about this as well. The child disobeyed the man, and then had the audacity to be so fragile! Emmerson wasn't even close to satisfied yet, which made his anger all the greater. He needed more. He needed more. He needed more!
Emmerson looked around, and spotted something that interested him: A group of young, young children. Almost immediately after spotting this, the man angrily stamped in their direction.
Those children were living, breathing, and energetic... until Emmerson arrived.

Since the friendly neighborhood overlords review every "spam" mod, what can we do to eliminate this problem? I'm not the only one browsing at -1, and we definitely need to nuke this amazingly dedicated troll.
I guess that protecting messages from being completely obliterated is a good thing overall, so maybe the Spam mod math should ignore the -1 floor ?

Mitch McConnell, smart guy, right? He used the Nuclear Option in the Senate. It worked great, we got Judge Gorsuch into the SC. And I asked Mitch, why don't you use that one all the time? And he said it could come back to bite us in the ass. And not in a good way. Because if the Dems ever get a majority in the Senate they'll want to go nuclear all the time.
My Generals, also very smart. I asked them, why don't we use our nuclear arsenal more often? Because it worked great on Japan. And they said it could come back to bite us in the ass. If we're not careful, it could zap our cyber. Mexico, not much cyber. There would be fallout, very bad for our dairy farmers, they'd have to throw out all the milk. And it could cause climate change, the nuclear winter. Cancun, it gets a little colder, it's still warm. Duluth, it gets colder, certain body parts may fall off. May freeze and fall off. Although sometimes I think we could use a little bit of that nuclear winter!
Let me tell you, Spam Modding is the same. Because it doesn't just block the folks you want to block. And it's not blocking the folks you want to block. Right? You do double or triple Spam Modding, maybe it blocks the tweets about baby rape, about baby murder. And maybe it blocks you. And maybe it blocks me. Let me tell you, if there wasn't Spam Modding, maybe the baby rape & murder person would get VERY BORED. Because she wouldn't be getting other people blocked. And she wouldn't be wasting the Administrators' time. DENUKE!!!
