菲律宾长滩岛之旅
http://openinx.github.io/2016/04/26/boracay
Apr 26, 2016. 菲律宾消费水平感觉比国内要低不少，货币单位为比索，1RMB = 7PHP(比索), 1$=45.5 PHP，想象一下，用100美金能在菲律宾换一沓PHP，这是怎样一种土豪的感觉。 我们的宾馆是Azalea酒店，相当于国内三星级，离西海滩5分钟步行距离 美味早餐自助餐 楼顶游泳池， 住起来还是非常舒服的。 I LOVE BORACAY . 我随意的把相机镜头对准了一对露天酒吧歌手，然后咔咔拍了一张照片，没想到女歌手通过话筒说了一句Thank you for taking photo for me.，我也是感动万分。 他们嘴里唱着韩国的nobody nobody but you , and nobody nobody . ，还连带一些自创的摇手动作，唱完一句，然后他们从船上一个倒翻筋斗，跃入海水中，再快速游到平衡杆上，依次五六回。 后面，直到我们下船，走了几百米，其中一个小孩一直跟着冯宇，冯宇很有礼貌的推脱，说现在没有零钱了，但小孩一直跟着冯宇，然后冯宇想起导游说过一句，中国话的 还要 就是菲律宾语言中的 不要 的意思，跟随的人马上就会走开。

Sep 16, 2014. Poblem A. Password Attacker. 假设有一组解为X1,.,Xn,那么该组解的排列之后有 M! Sigma(Xi) = M , Xi = 1 且 1 =i =N. 那么所求答案为dp[M, N]. 递推式为:. Dp[0, 0] = 1 dp[0, i] = 0 ( 1 =i =M ) dp[i,j] = dp[i-1, j] * j dp[i-1, j-1] * (n - (j-1). 其中dp[i-1,j-1] * (n - j 1) 代表前面i-1个密码串只用了j-1个字符，那么第i个密码可以从剩余的n-(j-1)个字符总任选一个。 第二类stirling数的意义是: 将n个不同的元素分成k个等价类, 记为S(n,k)， 递推式为:. S(n,k) = S(n-1, k-1) S(n-1, k) * k. Problem B. New Years Eve. 第i层的标号为j的杯子，由放在第i 1层的标号为j, j i, j i 1这三个杯子之上。 当第i层的杯子的酒满了时，会等分的溢出到第i 1层的j,j i,j i 1这三个杯子里。

HBase最佳实践－CMS GC调优 – 有态度的HBase/Spark/BigData
http://hbasefly.com/2016/08/09/hbase-cms-gc
Skip to main content. MemStoreLAB策略、Memstore Chuck Pool策略对写缓存Memstore进行优化开始，到0.96版本提出BucketCache以及堆外内存方案对读缓存BlockCache进行优化，再到后续2.0版本宣称会引入更多堆外内存，可见HBase会将堆外内存的使用作为优化GC的一个战略方向。 如果看官还对CMS GC不是很了解，可以参考笔者之前的另一篇文章 HBase GC的前生今生-身世篇 ，文中对JVM的内存结构以及CMS GC进行了相当详细的介绍。 1 Young区 一个对象初始化之后，首先会进入Eden区，当Eden区满之后会触发一次Minor GC，Minor GC会检查Eden区所有对象是否依旧存活 是否有其他对象引用 ，如果存活，会将其从Eden区拷贝到Survivor区，并将这些存活对象的age加一，而死亡的对象会被作为垃圾回收。 很显然，随着时间流逝，Tenured区也会被填充满，此时就会触发CMS GC old gc ，这种GC相对比较复杂，由5个步骤组成，详见参考文章。 第二部分 不同age对象分布区，第一列表示该Young区...

Skip to main content. Alter ’table1’ , CONFIGURATION = {‘hbase.store.engine.class’ = ‘org.apache.hadoop.hbase.regionserver.StripStoreEngine’, }. 1 减少参与compaction的文件数 这个很好理解，实现起来却比较麻烦，首先需要将文件根据rowkey、version或其他属性进行分割，再根据这些属性挑选部分重要的文件参与合并 另一方面，尽量不要合并那些大文件，减少参与合并的文件数。 3 小region更有利于compaction 大region会生成大量文件，不利于compaction 相反，小region只会生成少量文件，这些文件合并不会引起很大的IO放大. 2 所有数据能够全部加载到block cache RAM/SSD ，假如HBase有1T大小的SSD作为block cache，理论上就完全不需要做合并，因为所有读操作都是内存操作。 Tier-Based Compaction HBASE-7055 HBASE-14477. 此时如果需要执行compac...
