形式存储。然后问，问什么不能一个
cache line存一个，我说spatial locality保证性能最好啊，如果太分散性能不好。他
很不满意。然后说到了主存，他说无论这个 int在哪里，你访问的时间都是一样的。我说
当然不一样，你active 一个row，之后连续访问这个row的性能比你 重新active一个
row，要高很多。。。他说什么是active row，我解释，他极其不满意。。总之搞的我
一头雾水不知所云！这是什么面
试题啊！他然后就说不问了，再聊吧。就匆匆结束了。。。。
请教大牛，这是啥意思啊？ |

从这个来看，我觉得他问的和你回答的不是一个问题。一般的cache line size都是2的
指数，比如64，128什么的。20x20的int array，一行是80个bytes。他问的是不是为什
么一个cache line放不了这个数组的一行。
这个算architecture，不算很硬件的问题。 |

数据江湖，风起云涌。各路英豪，群雄逐鹿。
这是一个数据科学最好的时代，也是数据江湖最乱的时代。
那么在这么一个特殊的江湖里面浪，有什么兵器是值得我们去关注的呢？这篇文章列举
了一些常用方法（刀剑），并不涵盖工具与平台。就先让我们一起去看看这个排名不分

数据科学家Vincent Granville博士发表博文列举了数据科学家常用的45种技术。这是
个很适合初学者去逐个了解的列表。当然，这并不代表数据科学（统计学）的全部。虽
然他并没有提出自己的详细总结，但是有志于学习数据科学的同学不妨初步有个印象，
有不太熟悉的topic可以进一步去了解一下。另外我在后面也补充了我认为也值得学习
的领域，很多人都会在日常的数据实践中用到。多学有益于身心健康。

数学公理定理还是不行的。
另外一个问题是，对于具体加减乘除数学公理定理之类的，学校反正迟早

“第一，现在的最好的，不一定是将来的最好的。”
为啥会有这种情况发生？
举个实例，为啥会有人平面几何证明题很好，但是卡在立体几何和数学归纳法上？
我个人认为是卡在 spatial-temporal thinking 上，无法有效地把高维
reduce 成低维，或者从低阶 induce 到高阶。
那平面几何为啥能过关。我个人猜想是平面几何出题空间小（指通常考试难度
和时间限制下的出题空间），容易被穷举练习法击倒。。。

另外娃如果搞坏了，把家里地板弄脏了，自己会不会自己因此被

的概率又有多大，预估臭骂持续时间的 mean value 是多少，
median value 是多少，是不是呈现正态分布趋势，最后怎么

只要家长不是太笨，一天两个小时私教数学，两三年之内参加
