y***r 发帖数: 16594 | 5 EST 8:00 PM之前联系的,我都 $54.5 一个收了。
这东西不占地方,要帮我囤一段时间。给我的email,24小时要能check一次。vacation
或者啥的两个星期不能投递没关系,但要提前沟通好。
got enough了,暂时不要了。夜深人静的时候我付款。 |

Leetcode免费给你用 就别挑剔了。凡事要先从自身找问题
你那个测试不是大数据

一个魔方 Rubik's Cube 由 27 个小方块组成
如果外表刷满油漆,有多少个小方块是2面刷了油漆的?
(题目还可以扩展,有多少个是刷了 0, 1, 2, 3, 4 面油漆的) |

好多东西都可以教会孩子数学概念,我妈妈给我女儿买了4巧板,9连环,还有一种可以
搭金字塔的小珠子,包括这里toys are us可以买到的rubik cube, 都可以让孩子当玩
具玩,还能锻炼几何,数列,空间立体思维,这些不是直接做题,但达到的效果从长远
看是一样的。
我特别喜欢4巧板,一共4个木块,只有一个形状特殊一点,剩下的3个是常见形状,附
带的小册子里面有从简到难100个形状可以让孩子拼,很有意思的。

Winners and Losers in the Trump Tax Plan

The tax plan the Trump administration released Wednesday consists (so far)
of a single page of bullet points.
If this were a more rounded plan, we could wait for the tax wonks at various
think tanks to run it through their models and tell with some precision how
it would affect people at different income levels and who would benefit

s*********5 发帖数: 5637 | 46 这是他关于生死的那段名言,也是现在被引用最多的那段话,英文原文楼上可以找到。愿大家都能听到自己内心和直觉的召唤。。
“没有谁想死。甚至想去天堂的人也不想为了去天堂而死。但死亡是我们所有人的目的
地,没有谁跑掉过。本来也应该是这样,因为“死”很有可能就是“生”的最佳发明。
它是“生”的变革促进者。它把旧的清理掉,为新的让路。眼下你是新的,但不久过后
的某一天,你慢慢地就成了旧的,被清理掉了。很遗憾变化是如此剧烈,但这相当真实。
“你的时间是有限的,所以不要把它浪费在走别人的人生道路上面。不要受教条羁绊,
那是在用别人的思考成果活着。不要让他人意见的噪音淹没你内心深处的声音。最重要
的是,要有勇气听从内心和直觉的召唤。它们或多或少已经知道你真正想成为一个什么
样的人。其他一切都是次要的。”
[2005年6月在斯坦福大学(Stanford)毕业典礼上的演讲]
