How an American nightmare becomes real

The air was likely frigid as the hunter lit a small fire. The caribou would come in the morning—forced through the narrow strip of marshland where he camped. There was nowhere else to go. The land was flanked by water on both sides, and large stones had been laid out in slanting lines to funnel the animals into this bottleneck. The hunter struck his weapon to sharpen its edge in anticipation. In that moment, two glassy flakes splintered away from the point of impact and fell to his feet. They would be buried there for nearly 10,000 years. In 2013 those two shards of obsidian, a natural volcanic glass, would be recovered from a sample of earth, roughly the volume of a quart of milk, that was pulled from the bottom of Lake Huron, under 100 feet of water. And the story the flakes would tell was one of an even longer journey. John M. O’Shea of the University of Michigan and his team of underwater archaeologists have found something extraordinary about these two pieces of obsidian: they traveled nearly 2,500 miles from central Oregon before coming to rest at what is now the bottom of one of the Great Lakes. The samples were recovered from the Alpena-Amberley Ridge, a geologic formation below Lake Huron that connects Michigan to Ontario. O’Shea and his team have been diving at the site for more than a decade, collecting artifacts and environmental samples to prove that 9,000 years ago—as ice age glaciers were receding and the Great Lakes were forming—the area was dry land inhabited by Native Americans, who built hunting structures on it to trap and kill caribou. Obsidian was highly prized by ancient stone toolmakers. The flakes identified by Brendan Nash , a member of O’Shea’s team at the University of Michigan, have strike marks and sharp, feathered edges—both telltale signs of human modification. This evidence, combined with the distance to the obsidian’s original source, paint a picture of an extensive trade or exchange network that spanned the continent nearly 3,000 years after the end of the last ice age. Stone tools recovered from the Alpena-Amberley Ridge are much smaller than artifacts found nearby that date to the same time period. This suggests that a group of ancient people, with a different way of life and system of hunting, existed on the ridge around 9,000 years ago. In their study, O’Shea, Nash and their colleagues wrote, “ These specimens provide greater resolution , as well as greater complexity, to an important and poorly understood time period in the North American past.” In two small flakes, one can gain a view of a world lost to time and the waves.

When you specify a Pod, you can optionally specify how much of each resource a Container needs. The most common resources to specify are CPU and memory (RAM); there are others. When you specify the resource request for Containers in a Pod, the scheduler uses this information to decide which node to place the Pod on. When you specify a resource limit for a Container, the kubelet enforces those limits so that the running container is not allowed to use more of that resource than the limit you set.

“Don’t write clever code.” Why not? “Because it’s hard to understand.” People who say this think of clever code such as Duff’s Device: Duff's Device send(to, from, count) register short *to, *from; register count; { register n = (count + 7) / 8; switch (count % 8) { case 0: do { *to = *from++; case 7: *to = *from++; case 6: *to = *from++; case 5: *to = *from++; case 4: *to = *from++; case 3: *to = *from++; case 2: *to = *from++; case 1: *to = *from++; } while (--n > 0); } } This code is “clever” because it exploits knowledge about the language, in this case the peculiarities of fall-through.
