哪里可以买到呢？
谢谢

HP Slate 500 sees 'extraordinary demand,' experiences six-week shipping
delay (update)
Yes, the HP Slate 500 is officially backordered, less than a month after its
enterprising debut, and Hewlett-Packard claims it's because of "extraordina
ry demand," a phrase that's presently not quantifiable. The long and short o
f it, though, is that you're not getting one by Yuletide if you purchase the
pricey portable today, as you'll have to wait six weeks until they're ready
to ship out. Still, if your budding business bought in on day one, there's
still a chance it might arrive in time -- ours is due to our door in early D
ecember, if that gives you any idea. We've pinged HP for comment, and hope t
o hear back soon. We'll be sure to let you know just how "extraordinary" tho
se sales numbers might be.
Update: We've yet to hear back from HP proper, but a trusted tipster with a
contact inside HP spun us a very interesting tale -- HP reportedly only ever
planned a limited production run of 5,000 units, and received orders for 9,
000 instead. When demand outstripped supply, HP apparently had to re-hire pr
oduction workers just to get the presses printing out tablets again, and are
presently placating angry customers by offering them over $100 off their $8
00 purchase as apology.

最近把一些linux下dev的codes放到win环境下测试。直接装python&pip,没有用
anaconda，virtenv之类的，结果发现性能下降一大截，比如一些文件读还有计算下降
了20%-50%。一样的codes性能下降这么多，我怀疑可能是机器造成。linux用的是个i5-
4300M的机器， win是个amd FX8320的机器。内存都是16G，加ssd。还有一种可能是
intel的优化了python，有MLK(codes里边用了很多numpy).但是这个MLK似乎比较新，i5
还没有。
哪位有类似经验的，给科普一下。

这肯定不准，intel的 cache一般做的都比amd的大，所以贵。
你不如在windows 上装两个虚拟机，一样的配置，分别bench mark.

没办法，因为是国内的朋友要我买了给寄回去
请教local哪里有卖吗？

种子应该种不出大樱桃来，需要嫁接，国内多年前就有引种了，北京郊区果园里多的是
真要带只能买颗树，等秋天落叶后剪些枝条带回去，不过有点风险，被查到肯定会没收
一般lowes，homedepot之类的春天有，我不在LA，不知道当地哪儿有卖的

国内1000人民币的山寨板做的已经不错了，但还是都有些小问题
期待国内1500块钱以下更完美的板明年上旬上市呵呵

passmark上i5-4300M单线程1800, FX8320只有1400，numpy慢个30%太正常了。
