一个意思，特殊词汇

美式英语与英式英语不仅在读音上有区别，在用法、拼写和语法上也有所不同。下面我从Pronunciation、Vocabulary、Spelling、Grammar等几个方面来进行叙述。Pronunciation在读音上的一些重要差异：在美式英语中重读元音通常发音较长，如 packet 中的 æ 在英式英语中，辅音 r 只是在元音之前才发音（如 red 和 bedroom），其他情况下均不发音（如 car、learn、over）。在美式英语中， r 在任何位置都发音。在美式英语中，元音之间的 t 读成弱化的 d，因此 writer 和 rider 听起来相似，而说英式英语者通常将 t 读成 t。Vocabulary美式英语或在英式英语和美式英语中含义不同的单词均予以注明，如 cookie、elevator、trunk。Spelling本词典标有英式英语和美式英语的不同拼法，常见区别如下。在美式英语中，以 l 结尾的动词，如果最后一个音节为非重读音节，该动词的 -ing 形式和过去分词均不双写 l ，如 cancelling（英式拼法）；canceling（美式拼法）。以 -tre 结尾的词，美式英语拼作 -ter，如 centre（英式拼法）；center（美式拼法）。以 -our 结尾的词，美式英语通常拼作 -or，如 colour（英式拼法）；color（美式拼法）。以 -ogue 结尾的词，美式英语中通常拼作 -og，如 dialogue （英式拼法）；dialog （美式拼法）。在英式英语中，许多动词的结尾拼作 -ize 或 -ise 均可，但在美式英语中只能拼作 -ize，如realize/realise（英式拼法）；realize（美式拼法）。GrammarPresent perfect/Simple past 现在完成时；一般过去时在美式英语中，already、just 和 yet 可用于一般过去时；在英式英语中，这些词只能用于现在完成时。I have already given her the present. BrE我已把礼物送给她了。I already gave her the present. NAmE我已把礼物送给她了。I"ve just seen her. BrE我刚见过她。I just saw her. NAmE我刚见过她。Have you heard the news yet? BrE你听说这消息了吗？Did you hear the news yet? NAmE你听说这消息了吗？

noise-canceling 噪声消除例：An information processing apparatus includes a jack, a noise-canceling section, ajudgment section, and a first regulation section. 一种信息处理装置，包括：插孔、消除噪声部分、判断部分和第一调节部分。

受载期（Laydays）是指船舶预期到达装货港或地点，并作好装货准备的日期。 所谓解约日（Cancelling date），又称销约期，是在航次租船合同中规定的，船舶未能在合同中所规定的时间内到达指定的装货港并作好装货准备，租船人可以选择解除合同的日期。受载期与解约日的不同规定方法及后果 关于受载期与解约日的规定有两种基本形式，不同的形式导致的后果是不同的。 （1）解约日与受载期的最后一日重合 有的合同规定，解约日为受载期的最后一天（例如合同规定受载期为3月10日至15日，15日这天即为解约日），这就是所谓的解约日与受载期重合，例如，我国海商法第97条的规定即属此种情况。在这种规定下，如果船舶在受载期的最后一天仍未到港并准备好装货，承租人便有权解除合同。（2）解约日在受载期届满之后。有的合同所规定的解约日是在受载期届满后的某一天，此种规定即属于二者相脱离的情况。在此种条款下，如果船舶在合同所规定的受载期之后的解约日这一天还未到达，租船人便有权解除合同。如果船舶仅仅超过了受载期，但并未超过解约日，则虽然出租人违约，承租人仍然无权解除合同。

1．英语动词加-ing,通常是在原形词尾直接加-ing构成：cough—coughing,climb—climbing,stand—standing,fight—fighting 2．以-e结尾的动词 （1）如果动词原形以一辅音加一不发音的-e结尾,一般应去掉e再加ing： write—writing,hope—hoping,care—caring,stare—staring,plane—planing,have—having,save—saving,produce—producing,breathe—breathing （2）以-ie结尾的动词应先将e去掉,将i变成y然后再加-ing： die—dying,tie—tying,vie—vying,lie—lying （3）以-ee,－oe,－ye结尾的动词加-ing时应保留词尾e： see—seeing,flee—fleeing,free—freeing,agree—agreeing,hoe—hoeing,dye—dyeing,eye—eyeing （4）以-ue结尾的动词大多应先去e再加-ing： sue—suing,imbue—imbuing,construe—construing,pursue—pursuing, rue—ruing 有时,词尾e可去掉也可保留： glue—gluing或 glueing,cue—cuing或 cueing,blue—blueing或 bluing, true—truing或trueing,clue—clueing或cluing 3．以一元音加一辅音结尾的动词 （1）如果动词最后一音节为重读闭音节,最后一个字母需要重复： run—running,stop—stopping,hop—hopping,plan—planning,star—starring,control—controlling但辅音x是个例外,无需重复（x其实起着两个辅音的作用）： tax—taxing,relax—relaxing （2）如果动词最后一个音节为次重读音节,最后一个字母有时也重复： kidnap—kidnapping或kidnaping,program—programming或programing （3）如果动词最后一个音节为非重读音节,最后一个字母大多无需重复： open—opening,offer—offering,audit—auditing但在有些动词中,重复或不重复均可： worship—worshiping或 worshipping,focus—focusing或 focussing,cancel—canceling或cancelling,travel—traveling或travelling 以非重读的-el结尾的动词加-ing时,英国英语习惯于重复词尾l,而美国英语则习惯于不重复1. 4．若动词以一元音加一半元音（y或w）结尾,可直接加-ing： pay—paying,throw—throwing,follow—following,draw—drawing,employ—employing 5．以-ic结尾的动词应先在字母c后加一字母k再加-ing： frolic—frolicking,panic—panicking,mimic—mimicking,picnic—picnicking,traffic—trafficking 这主要是为在动词后加-ing之后保留/k/这个音.若不在字母c后加字母k而直接加-ing,字母 c的发音就不再是/k/,而是/s/：

目前比较多的解决方案有几个： 一、结合MQ消息中间件实现的可靠消息最终一致性 二、TCC补偿性事务解决方案 三、最大努力通知型方案第一种方案：可靠消息最终一致性，需要业务系统结合MQ消息中间件实现，在实现过程中需要保证消息的成功发送及成功消费。即需要通过业务系统控制MQ的消息状态 第二种方案：TCC补偿性，分为三个阶段TRYING-CONFIRMING-CANCELING。每个阶段做不同的处理。 TRYING阶段主要是对业务系统进行检测及资源预留CONFIRMING阶段是做业务提交，通过TRYING阶段执行成功后，再执行该阶段。默认如果TRYING阶段执行成功，CONFIRMING就一定能成功。 CANCELING阶段是回对业务做回滚，在TRYING阶段中，如果存在分支事务TRYING失败，则需要调用CANCELING将已预留的资源进行释放。第三种方案：最大努力通知xing型，这种方案主要用在与第三方系统通讯时，比如：调用微信或支付宝支付后的支付结果通知。这种方案也是结合MQ进行实现，例如：通过MQ发送http请求，设置最大通知次数。达到通知次数后即不再通知。 具体的案例你也可以参考下这篇博客，它上面有完整的电商系统分布式事务实现案例：

目前比较多的解决方案有几个： 一、结合MQ消息中间件实现的可靠消息最终一致性 二、TCC补偿性事务解决方案 三、最大努力通知型方案第一种方案：可靠消息最终一致性，需要业务系统结合MQ消息中间件实现，在实现过程中需要保证消息的成功发送及成功消费。即需要通过业务系统控制MQ的消息状态 第二种方案：TCC补偿性，分为三个阶段TRYING-CONFIRMING-CANCELING。每个阶段做不同的处理。 TRYING阶段主要是对业务系统进行检测及资源预留CONFIRMING阶段是做业务提交，通过TRYING阶段执行成功后，再执行该阶段。默认如果TRYING阶段执行成功，CONFIRMING就一定能成功。 CANCELING阶段是回对业务做回滚，在TRYING阶段中，如果存在分支事务TRYING失败，则需要调用CANCELING将已预留的资源进行释放。第三种方案：最大努力通知xing型，这种方案主要用在与第三方系统通讯时，比如：调用微信或支付宝支付后的支付结果通知。这种方案也是结合MQ进行实现，例如：通过MQ发送http请求，设置最大通知次数。达到通知次数后即不再通知。

简单之美 | Apache Flink：特性、概念、组件栈、架构及原理分析 http://shiyanjun.cn/archives/1508.html Apache Flink是一个面向分布式数据流处理和批量数据处理的开源计算平台，它能够基于同一个Flink运行时（Flink Runtime），提供支持流处理和批处理两种类型应用的功能。现有的开源计算方案，会把流处理和批处理作为两种不同的应用类型，因为他们它们所提供的SLA是完全不相同的：流处理一般需要支持低延迟、Exactly-once保证，而批处理需要支持高吞吐、高效处理，所以在实现的时候通常是分别给出两套实现方法，或者通过一个独立的开源框架来实现其中每一种处理方案。例如，实现批处理的开源方案有MapReduce、Tez、Crunch、Spark，实现流处理的开源方案有Samza、Storm。Flink在实现流处理和批处理时，与传统的一些方案完全不同，它从另一个视角看待流处理和批处理，将二者统一起来：Flink是完全支持流处理，也就是说作为流处理看待时输入数据流是无界的；批处理被作为一种特殊的流处理，只是它的输入数据流被定义为有界的。基于同一个Flink运行时（Flink Runtime），分别提供了流处理和批处理API，而这两种API也是实现上层面向流处理、批处理类型应用框架的基础。 基本特性 关于Flink所支持的特性，我这里只是通过分类的方式简单做一下梳理，涉及到具体的一些概念及其原理会在后面的部分做详细说明。 流处理特性 支持高吞吐、低延迟、高性能的流处理 支持带有事件时间的窗口（Window）操作 支持有状态计算的Exactly-once语义 支持高度灵活的窗口（Window）操作，支持基于time、count、session，以及data-driven的窗口操作 支持具有Backpressure功能的持续流模型 支持基于轻量级分布式快照（Snapshot）实现的容错 一个运行时同时支持Batch on Streaming处理和Streaming处理 Flink在JVM内部实现了自己的内存管理 支持迭代计算 支持程序自动优化：避免特定情况下Shuffle、排序等昂贵操作，中间结果有必要进行缓存 API支持 对Streaming数据类应用，提供DataStream API 对批处理类应用，提供DataSet API（支持Java/Scala） Libraries支持 支持机器学习（FlinkML） 支持图分析（Gelly） 支持关系数据处理（Table） 支持复杂事件处理（CEP） 整合支持 支持Flink on YARN 支持HDFS 支持来自Kafka的输入数据 支持Apache HBase 支持Hadoop程序 支持Tachyon 支持ElasticSearch 支持RabbitMQ 支持Apache Storm 支持S3 支持XtreemFS 基本概念 Stream & Transformation & Operator 用户实现的Flink程序是由Stream和Transformation这两个基本构建块组成，其中Stream是一个中间结果数据，而Transformation是一个操作，它对一个或多个输入Stream进行计算处理，输出一个或多个结果Stream。当一个Flink程序被执行的时候，它会被映射为Streaming Dataflow。一个Streaming Dataflow是由一组Stream和Transformation Operator组成，它类似于一个DAG图，在启动的时候从一个或多个Source Operator开始，结束于一个或多个Sink Operator。下面是一个由Flink程序映射为Streaming Dataflow的示意图，如下所示： 比如从Source[1]到map()[1]，它保持了Source的分区特性（Partitioning）和分区内元素处理的有序性，也就是说map()[1]的Subtask看到数据流中记录的顺序，与Source[1]中看到的记录顺序是一致的。 Redistribution模式 这种模式改变了输入数据流的分区，比如从map()[1]、map()[2]到keyBy()/window()/apply()[1]、keyBy()/window()/apply()[2]，上游的Subtask向下游的多个不同的Subtask发送数据，改变了数据流的分区，这与实际应用所选择的Operator有关系。另外，Source Operator对应2个Subtask，所以并行度为2，而Sink Operator的Subtask只有1个，故而并行度为1。 Task & Operator Chain 在Flink分布式执行环境中，会将多个Operator Subtask串起来组成一个Operator Chain，实际上就是一个执行链，每个执行链会在TaskManager上一个独立的线程中执行，如下图所示： 在Flink集群启动的时候，TaskManager会向JobManager注册，如果注册成功，则JobManager会向TaskManager回复消息AcknowledgeRegistration。 SubmitJob Flink程序内部通过Client向JobManager提交Flink Job，其中在消息SubmitJob中以JobGraph形式描述了Job的基本信息。 CancelJob 请求取消一个Flink Job的执行，CancelJob消息中包含了Job的ID，如果成功则返回消息CancellationSuccess，失败则返回消息CancellationFailure。 UpdateTaskExecutionState TaskManager会向JobManager请求更新ExecutionGraph中的ExecutionVertex的状态信息，更新成功则返回true。 RequestNextInputSplit 运行在TaskManager上面的Task，请求获取下一个要处理的输入Split，成功则返回NextInputSplit。 JobStatusChanged ExecutionGraph向JobManager发送该消息，用来表示Flink Job的状态发生的变化，例如：RUNNING、CANCELING、FINISHED等。 TaskManager TaskManager也是一个Actor，它是实际负责执行计算的Worker，在其上执行Flink Job的一组Task。每个TaskManager负责管理其所在节点上的资源信息，如内存、磁盘、网络，在启动的时候将资源的状态向JobManager汇报。TaskManager端可以分成两个阶段： 注册阶段 TaskManager会向JobManager注册，发送RegisterTaskManager消息，等待JobManager返回AcknowledgeRegistration，然后TaskManager就可以进行初始化过程。 可操作阶段 该阶段TaskManager可以接收并处理与Task有关的消息，如SubmitTask、CancelTask、FailTask。如果TaskManager无法连接到JobManager，这是TaskManager就失去了与JobManager的联系，会自动进入“注册阶段”，只有完成注册才能继续处理Task相关的消息。 Client 当用户提交一个Flink程序时，会首先创建一个Client，该Client首先会对用户提交的Flink程序进行预处理，并提交到Flink集群中处理，所以Client需要从用户提交的Flink程序配置中获取JobManager的地址，并建立到JobManager的连接，将Flink Job提交给JobManager。Client会将用户提交的Flink程序组装一个JobGraph， 并且是以JobGraph的形式提交的。一个JobGraph是一个Flink Dataflow，它由多个JobVertex组成的DAG。其中，一个JobGraph包含了一个Flink程序的如下信息：JobID、Job名称、配置信息、一组JobVertex等。 组件栈 Flink是一个分层架构的系统，每一层所包含的组件都提供了特定的抽象，用来服务于上层组件。Flink分层的组件栈如下图所示： 了解YARN的话，对上图的原理非常熟悉，实际Flink也实现了满足在YARN集群上运行的各个组件：Flink YARN Client负责与YARN RM通信协商资源请求，Flink JobManager和Flink TaskManager分别申请到Container去运行各自的进程。通过上图可以看到，YARN AM与Flink JobManager在同一个Container中，这样AM可以知道Flink JobManager的地址，从而AM可以申请Container去启动Flink TaskManager。待Flink成功运行在YARN集群上，Flink YARN Client就可以提交Flink Job到Flink JobManager，并进行后续的映射、调度和计算处理。 Runtime层 Runtime层提供了支持Flink计算的全部核心实现，比如：支持分布式Stream处理、JobGraph到ExecutionGraph的映射、调度等等，为上层API层提供基础服务。 API层 API层主要实现了面向无界Stream的流处理和面向Batch的批处理API，其中面向流处理对应DataStream API，面向批处理对应DataSet API。 Libraries层 该层也可以称为Flink应用框架层，根据API层的划分，在API层之上构建的满足特定应用的实现计算框架，也分别对应于面向流处理和面向批处理两类。面向流处理支持：CEP（复杂事件处理）、基于SQL-like的操作（基于Table的关系操作）；面向批处理支持：FlinkML（机器学习库）、Gelly（图处理）。 内部原理 容错机制 Flink基于Checkpoint机制实现容错，它的原理是不断地生成分布式Streaming数据流Snapshot。在流处理失败时，通过这些Snapshot可以恢复数据流处理。理解Flink的容错机制，首先需要了解一下Barrier这个概念：Stream Barrier是Flink分布式Snapshotting中的核心元素，它会作为数据流的记录被同等看待，被插入到数据流中，将数据流中记录的进行分组，并沿着数据流的方向向前推进。每个Barrier会携带一个Snapshot ID，属于该Snapshot的记录会被推向该Barrier的前方。因为Barrier非常轻量，所以并不会中断数据流。带有Barrier的数据流，如下图所示： 接收到Barrier n的Stream被临时搁置，来自这些Stream的记录不会被处理，而是被放在一个Buffer中 一旦最后一个Stream接收到Barrier n，Operator会emit所有暂存在Buffer中的记录，然后向Checkpoint Coordinator发送Snapshot n 继续处理来自多个Stream的记录 基于Stream Aligning操作能够实现Exactly Once语义，但是也会给流处理应用带来延迟，因为为了排列对齐Barrier，会暂时缓存一部分Stream的记录到Buffer中，尤其是在数据流并行度很高的场景下可能更加明显，通常以最迟对齐Barrier的一个Stream为处理Buffer中缓存记录的时刻点。在Flink中，提供了一个开关，选择是否使用Stream Aligning，如果关掉则Exactly Once会变成At least once。 调度机制 在JobManager端，会接收到Client提交的JobGraph形式的Flink Job，JobManager会将一个JobGraph转换映射为一个ExecutionGraph，如下图所示： 迭代机制 机器学习和图计算应用，都会使用到迭代计算，Flink通过在迭代Operator中定义Step函数来实现迭代算法，这种迭代算法包括Iterate和Delta Iterate两种类型，在实现上它们反复地在当前迭代状态上调用Step函数，直到满足给定的条件才会停止迭代。下面，对Iterate和Delta Iterate两种类型的迭代算法原理进行说明： Iterate Iterate Operator是一种简单的迭代形式：每一轮迭代，Step函数的输入或者是输入的整个数据集，或者是上一轮迭代的结果，通过该轮迭代计算出下一轮计算所需要的输入（也称为Next Partial Solution），满足迭代的终止条件后，会输出最终迭代结果，具体执行流程如下图所示： Delta Iterate Operator实现了增量迭代，它的实现原理如下图所示： 另外，Flink还提供了3个参数来配置Backpressure监控行为： 参数名称 默认值 说明 jobmanager.web.backpressure.refresh-interval 60000 默认1分钟，表示采样统计结果刷新时间间隔 jobmanager.web.backpressure.num-samples 100 评估Backpressure状态，所使用的堆栈跟踪调用次数 jobmanager.web.backpressure.delay-between-samples 50 默认50毫秒，表示对一个Job的每个Task依次调用的时间间隔 通过上面个定义的Backpressure状态，以及调整相应的参数，可以确定当前运行的Job的状态是否正常，并且保证不影响JobManager提供服务。 参考链接 http://flink.apache.org/ http://flink.apache.org/features.html
