发帖数: 1969 | 1 空间不够，文件太大。分成几个chunk排序，然后把chunk两两merge。
可是，每个chunk的大小和memory一样大。那merge的时候，怎么merge啊？因为只能
merge一半，而且，根本读不下2个chunk啊。。。

发帖数: 6519 | 3 你这问题的format存在很大问题，要想让人给思路，至少你的问题要问的明白，我姑且
猜一下吧：
1. 一个client 对一个server
2. 多个client 对一个server
3. 一个client 对多个server
4. 多个client 对多个server
可以把1和2算做一类问题，3和4算做第二类问题
第一类问题就是传呗，一个server最终也就那么多cpu/ram/hdd，没啥花样
第二类问题，多个server可以选其中1-2个做master，其余的全是chunk server。
client上传的时候，不要经过master，master直接分配几个chunk server给client传文
件，其中一个chunk server可以作为leader，文件partition之后，一式三份保存在不
同的chunk server；文件分隔和保存记录可以存在master上 |

发帖数: 10908 | 4 我有另一个大胆假设。也可能 WIC-V 的 working memory 测试，测试的并不是
working memory 本身，测试的是 working memory 的 domain-general chunking 能力
（correlation 还是 causation 另说）。
这是因为我们的考试，包括智商测试的其他项目，更多的是 controlled environment
，也就是更多的是 routine fashion, predictable。
虽然大部分情况下，人的大脑有自我保护系统，即使在考试环境下，也不会过度发展
veli veli domain-specific 的 chunking（俗称，新东方型死记硬背红宝书狠刷题型
应考）。关于这点保护，看看大部分人考完 GRE 立马把红宝书给扔了烧了踩了埋了此

但上面这个保护是 “大部分情况”，并不是所有。如果这个保护机制失效，那么所有
跟周围考试风格类似的考试，可能都会被 veli veli domain-specific 的 chunking

发帖数: 10908 | 5 刚才敲的有点太快太乱，补充/修正一下就是：
"domain-specific vs domain-general" 以及 "routine vs non-routine" 都是表象。
其背后的实质因子，应该是 lower-order chunking vs higher-order chunking。
举个例子就是 superior on "lexicon (词汇) chunking", but poorly on "pragmatic
(上下文语境) chunking"，如果这种不对称的情况如果严重的话，可能会造成问题。

发帖数: 10908 | 6 所以从这个角度说，心算 AIME 15 道天空题，之所以要心算，既不是放着草稿纸不用

整 higher order non-routine chunking 来对付闻所未闻的题目。
而这种 higher order non-routine chunking 应该还分成前台和后台。前台是按既定
方针进行 explicit 的 chunking，干实事。而后台 implicit memory 的任务就是盯的
前台的行为，同时大略分析前台扔出来的垃圾。。。如果发现此路看起来不通，前台还

1 雷奥纳多的确杀了自己的妻子，在片中最开始的梦里，他从后面抱着Dolores，
Dolores是腹部流血的。这和最后的剧情吻合。
2 Dolores淹死了自己的三个孩子。因为雷奥纳多受到战争的创伤而染上了酗酒的毛病
。也因为这样，经常折磨妻子和孩子。
3 雷奥纳多叫Teddy，而不叫Andrew。
4 一共有三个Marshall在岛上。雷奥纳多，Chunk，George。雷奥纳多和Chunk一起上岛
。George是后来来搭救雷奥纳多的。但是却被抓住，要做手术。Chunk则是被威胁从而
协助医院。最后，在雷奥纳多要去做手术的时候。Chunk喊雷奥纳多“Teddy”。
5 雷奥纳多被医院的药物和医生进行心理诱导，让雷奥纳多觉得自己是一个彻头彻尾的
疯子。
6 电影最后，雷奥纳多知道要接受手术。有一个镜头特写了一个工作人员拿着白布包。
里面会是手术刀？还是其他的什么？雷奥纳多也看到了。
7 电影结尾没表雷奥纳多到底接受手术没有。我的看法是，雷奥纳多不会接受手术。他

would you use to sort the file and why?
书里给出的解法是：
1. Divide the file into K chunks, where X * K = 2 GB. Bring each chunk into
memory and sort the lines as usual using any O(n log n) algorithm. Save the
lines back to the file.
2. Now bring the next chunk into memory and sort.
3. Once we’re done, merge them one by one.
其中一个假定是每次不使用超过X的memory,但是最后一步怎么能满足这个条件呢？ |

and so on, 都记录各个shard上的最小值，exponential。共有nlogn个纪录。
query的时候，根据A和B的值，得到对应的chunk，再得到需要read哪些shard （logN个
）。在这些shard的最小中选择最小，返回。 |

也许是logN的query
building个index，如下：
选择一个chunk size，比如是256. 然后把原来数组scan 一边，每256个选个最小值保

用udp传, chunk by chunk。 加checksum验证 避免用tcp，慢。
存放地點放到缓存。不要直接写磁盘，异步往磁盘写 可以增加吞吐。
数据直接在客户端md5加密。安全性基本没问题了，处理好key的交换。
验证数据格式，只存储可识别的文件，未知格式文件拒绝存储。 |

发帖数: 2697 | 48 我来抛砖引个玉吧。是不是首先还得计算出个dp[][]数组表示i到j是不是chunked
palindrome，后面就跟palindrome partition一样了。所以关键是如何构造那个dp[][]
也就转化为给定一个String，如何判断它是不是chunked palindrome。
boolean isChunkedPalindrome(String s) {
int left = 0, right = s.length() - 1;
LinkedList queue = new LinkedList();
int[] cnt = new int[256];
while (left < right) {
char leftChar = s.charAt(left);
char rightChar = s.charAt(right);
queue.add(rightChar);
cnt[leftChar]++;
cnt[righ... 阅读全帖 |

We know that fish can be very nutritious and are packed with great nutrients
such as omega-3’s, the B vitamins and lean protein. But unfortunately,
fish can also have some unhealthy contaminants. Mercury is a contaminant
found in fish that can affect brain development and the nervous system. The
FDA has released guidelines for children, women who are pregnant and women
