今天读了几篇分布式相关的内容,记录一下.非经典论文,非系统化阅读,非严谨思考和总结.主要的着眼点在于分布式存储:好处是,跨越单台物理机器的计算和存储能力的限制,防止单点故障(single point of failure):常见方法是,做数据分区(data partition / sharding)以横向扩展,做数据复制(data replication)增加冗余度:难点是,如何在数据一致性(consistency).系统可用性(availability).分区容忍度(partition tol

SQL Server 阻止了对组件 'Ad Hoc Distributed Queries' 的 STATEMENT'OpenRowset/OpenDatasource' 的访问,因为此组件已作为此服务器安全配置的一部分而被关闭.系统管理员可以通过使用 sp_configure 启用 'Ad Hoc Distributed Queries'.有关启用 'Ad Hoc Distributed Queries' 的详细信息,请参阅 SQL Server 联机丛书中的 "外围应用配置器".
A first thought system architecture (pulling mode) is one that the server doesn't keep client information and the client takes a more active part in retrieving updates from the server, Note the previous model manager which is responsible for both the
昨天在审核资讯翻译的时候遇到这两个单词,文章里讲的也不清楚,感觉翻译的也不到位.今天就单独拿出来比较一下吧.尽管这两个单词相似,它们的具体实现方法还是有很大区别的. Distributional word representation主要是基于Distributional假说:"linguistic items with similar distributions have similar meanings" ,翻译过来差不多是“语言项若有像是的分布,则他们的语义也接近”.它一般是根据
