Consumers may see a discrepancy between reported capacity and actual

However, the operating system usually calculates capacity in binary format,
causing traditional HDD and SSD to show a lower capacity in Windows. In the
case of SSDs, some of the capacity is reserved for formatting and redundancy
for wear leveling. These reserved areas on an SSD may occupy up to 5% of

发帖数: 1700 | 24 network capacity的定义是很难的
不能简单地推广点对点通信的capacity
1.点对点通信的时候最重要的一个指标是transmission rate，所以Shannon建模的时候
假设两点间保持通信然后导出可以达到的最高rate
网络通信不是这么一回事，网络不可能始终保持饱和（即所有的link都始终保持通信）
，网络一个重要的特性就是burstiness，建模的时候要考虑这个因素
2.网络的另一个重要指标是delay，这在Shannon点对点通信的model中也是不考虑的（
关注的是无错信息传输，更准确的说是出错概率趋近于0，两者其实差别挺大，前者叫
Zero-Error Capacity，Shannon后来有一篇专门的paper讲这个，这个capacity是不能
用互信息来得到的，对大多数信道来说还是open的），网络的general capacity中应该
包含delay这个因素（点对点通信model中假设delay可以无穷大）

马英九指出，这个法庭的存在，应该是为国际争端定纷息争、避免走上冲突甚至战争。但是，这样的仲裁结果，不但没有排难解纷，反而增加了冲突的可能。「在背後操控的势力，看似赢了面子，其实却输了裡子。」
「菲律宾对中国」南海仲裁案，常设仲裁法院今天公布结果，称中国大陆在9段线范围内主张的历史权利没有法律依据，而南沙群岛的所有海上地物，均为礁岩，包括太平岛在内。
马英九晚间在脸书发文表示，从去年12月到今年5月，包括他在内，150多名部会首长、国内外学者专家和国内外媒体，都访问太平岛，亲眼见证这个淡水充裕（南沙唯一）、农产丰富、生活机能完整的岛屿，完全符合「联合国海洋法公约」第121条关于「岛屿」必须「维持人类生存与自身经济生活」的要件。
他说，至今年4月底为止，也有430篇国际媒体完整陈述「太平岛是岛」的事实。太平岛是「岛」不是「礁」，已是国内外多数人的共识。

(菲律宾共和国 v. 中华人民共和国)
海牙，2016年7月12日
仲裁庭发布裁决
今日，根据《联合国海洋法公约》(“《公约》”)附件七组成的仲裁庭就菲律宾共和国
对中华人民共和国提起的仲裁案作出了一致裁决。
该仲裁案涉及在南海的历史性权利的作用和海洋权利的渊源、某些岛礁的地位及其能够
产生的海洋权利，以及菲律宾声称违反了《公约》的中国某些行为的合法性问题。考虑
到《公约》对强制争端解决的限制性规定，仲裁庭强调，它既不对任何涉及陆地领土主
权的问题进行裁决，也不划定当事双方之间的任何边界。
中国反复申明“其不接受、不参与由菲律宾单方面提起的仲裁”。然而，《公约》附件
七规定，“争端一方缺席或不对案件进行辩护，应不妨碍程序的进行”。附件七同时规
定，在争端一方不参与程序的情况下，仲裁庭“必须不但查明对该争端确有管辖权，而
且查明所提要求在事实上和法庭上均确有根据”。因此，在整个程序中，仲裁庭采取了
一些步骤验证菲律宾诉求的正确性，包括要求菲律宾提交进一步的书面论证，在两次庭

发帖数: 102 | 44 之前面试 遇到过LRU 这道题，面试之前准备过，就直接说了 用hashmap 和
linkedlist。 但是实现起来发现很不好处理 删除命令。 由于是最后一题时间有限就
没在写下去。不过最后一再追问下，知道使用Doublelinkedlist。。。
不过感谢国人面试官，还是给过了。 再次鸣谢下。
然后看到leetcode有这道题（稍微有点不一样）就又做了下，还是问题重重，不得不感
叹自己实力的差距, 不过最后还是通过了，代码如下：
1.由于是菜鸟，代码很丑很啰嗦，希望大神们指点要怎么改进。
2.小弟有一事不明，为啥LRU 还要有（key,value）查询？ 现实中，不就只有一个
value吗？然后HashMap 存。 现实中的LRU 每个内存有key
这个值吗？
希望帮忙讲解下LRU。

manager are okay. But the VP of engineering is joke. He was disrespectful. I
walked out after the interview:( Very bad experience for me.
Wish you the best luck! 他家的问题会问多线程和系统设计。Hope it helps.

不好意思，我略过了一些步骤。
把每个vertice分拆成两个vertice, create two edges between them, one with INF
capacity and 0 cost, one with capacity of 1 and cost of -money. Edges
between the original vertices stays the same, with 0 cost and INF capacity(
or capacity of 2, does not matter).
This is the standard way to move cost/capacity to edges. |
