It's the Full Moon tonight, and this month's is an extra special one, it's also a total lunar eclipse. This will turn the Moon a red color, earning it the nickname of "Blood Moon". Moon gazers in North America, parts of Asia, Australia, and the Pacific will be lucky enough to see this phenomenon, but for those elsewhere, it'll still be a big and bright moon with lots of features to spot on its surface. Keep reading to find out exactly what you can see.
Admittedly, the new iPad Airs aren’t drastically different from their predecessors, but they do stand out due to their performance gains. They now run on Apple’s M4 chip, which Apple says makes them up to 30 percent faster (and over twice as fast as the M1 Air from 2020). The new models also offer 12GB of RAM instead of 8GB, which should help with multitasking and more demanding apps.，推荐阅读PDF资料获取更多信息
一个连锁反应是，高算力需求推高能耗，而高能耗产生的巨大热量，又对散热系统构成了极限挑战，传统的风冷技术已触达瓶颈，散热本身成为制约算力密度提升的“热墙”。，推荐阅读PDF资料获取更多信息
The big picture here is about how brutally complex it is to build a real database on dumb cloud primitives. They had to implement Record Managers, Page Managers, and buffer pools entirely on the client side, in order to cluster tiny records into pages. For distributed coordination, they hack SQS into a locking system with dedicated LOCK queues and carefully timed tokens. On top of that, they have to handle SQS quirks, with idempotent log records as we discussed above. The engineering effort is massive.
