    • 把non-transactional resource和transactional resource放在一个事务中，就是把对non-transactional resource的操作放在最后。
      很土的一个方式，原来也是这么做的，只是没总结出来。 - post by lithium
  • By putting the interaction with the non-transactional
    resource as the final action in the transaction, we limit the chance of error
    occurring after interaction with the non-transactional resource
  • in a pseudo-transaction that has any number of interactions
    with transactional resources and a single interaction with a non-transactional
    resource, make the non-transactional interaction the final activity in the
    pseudo-transaction.
  • To achieve a pseudo transaction, we encapsulate each non-transactional interaction
    into a Command object. In each Command object, we implement a rollback method,
    which is called if a rollback of the pseudo-transaction occurs sometime after
    the Command has been executed.

创业不嫌晚

刘伯温，名刘基，字伯温，明朝开国元勋，上通天文，下晓地理，能掐会算，前知五百年，后知五百载，被后人比作为诸葛亮。
这么大的一位能人，最初为元朝效力25年，宦海沉浮四起四落，48岁弃官回家乡隐居，50岁被朱元璋盛情邀请出山，进献"十八策"，论天下安危，在创建明王朝的过程中，立下了汗马功劳。
刘伯温50岁才追随朱元璋创业，所以，创业不嫌晚。

牛年到了

一年时间可真快呀，完全没有征兆就过去了。
去年的大年三十在干嘛，在搜陈冠希的照片，呵呵，那时还在广州，天河公园旁边租住的房子里。今天呢，已经身在杭州。鞭炮声渐渐的淡去了，我却不想入睡。我太不想让这个时刻就这么过去了!生活，就像从手边流过的水，你怎么努力也阻挡不了它，也抓不住他，眼睁睁的看着它流过。我特别的怀旧，但却没时间回忆过去，只是一路拼命向前奔跑，好像在追逐我的目标，但那真的是我想要的吗。

也许在特别的日子里看着时间的流过，触发了我特别的感伤，其实每一天不是一样在过。打起精神来，还有很多有意义的事要做。放下理想，那一瞬间可能会很轻松，但我却不知道该如何前行。没办法，有抱负的中年。

  • The source and target servers do not have to be in the same cluster
    which makes bridging suitable for reliably sending messages from one
    cluster to another, for instance across a WAN, and where the connection
    may be unreliable.
  • The bridge has built in resilience to failure so if the source or
    target server connetion is lost

• 多核的软肋：阿姆达定律 - apple4us

  tags: concurrency

  • 阿姆达定律讲的是这么一件事：一个程序存在两部分，

    只能串行计算的部分 S，和能够并行计算地部分 P。

    两部分之和是整个程序，因此 S+P=1。

    这个程序如果在一个具有N个核心的处理器上运行，

    那么和它在一个单核处理器上运行相比，速度的提升是 1/(S
    + P/N)。当 N 趋近于无穷大时（即假设我们有无穷多个核心），

    速度提升的上限是 1/S，

    即速度提升的上限取决于程序不能被并行计算的部分。
