ruby difference engine

由 懵懂的女人 提交于 2019-12-19 11:57:29
问题 Looking for a Ruby differencing engine. So you can do some of the same things meld viewer does. For example you have this first set of code per line: String1 String2 String3 2nd set: String1 String3 String4 The diff would come out to show lines 2 and 3 are different. I already am using this one: http://github.com/pvande/differ, but it's definitely not perfect but pretty good. I would like to add on to it, however I'm trying to find some knowledge on another one before going further with this

How can I make a Ruby gem package copy files to arbitrary locations?

问题 Suppose you have a software package. You want to make it a gem, because gems are the de facto standard way to distribute anything in the Ruby world. Gems are great -- for libraries. But for real applications, the Rubygems system seems lacking. Only "recently" did they introduce a way to mark executables to be placed in somewhere in the system wide executable PATH. Unfortunately, Ruby gems still seems to be wanting in other aspects of software packaging, namely putting configuration files in

mysql2 gem Can't build native extensions

由 本秂侑毒 提交于 2019-12-19 02:29:25
问题 Our intern's computer is having problems installing the mysql2 gem. We just upgraded his computer from OS X 10.6 to 10.8 (Mountain Lion). I have tried installing mysql through homebrew and through the 64 bit DMG installer. I also tried symlinking to the dev tools (as pointed out here: Not able to install some gems after mountain lion upgrade). We have Xcode (4.4) installed and the command line tools installed. We tried a reboot after installing the command line tools. This is his PATH

第七章· Redis Cluster 核心技术

由 為{幸葍}努か 提交于 2019-12-18 23:19:57
一、Redis Cluster 分布式集群 1.什么是Redis Cluster 1）Redis集群是一个可以在多个Redis节点之间进行数据共享的设施（installation）。 2）Redis集群不支持那些需要同时处理多个键的Redis命令，因为执行这些命令需要在多个Redis节点之间移动数据，并且在高负载的情况下，这些命令将降低Redis集群的性能，并导致不可预测的行为。 3）Redis集群通过分区（partition）来提供一定程度的可用性（availability）：即使集群中有一部分节点失效或者无法进行通讯，集群也可以继续处理命令请求。 4）Redis集群有将数据自动切分（split）到多个节点的能力。 2.Redis Cluster的特点 高性能 1.在多酚片节点中，将16384个槽位，均匀分布到多个分片节点中 2.存数据时，将key做crc16（key），然后和16384进行取模，得出槽位值（0-16384之间） 3.根据计算得出的槽位值，找到相对应的分片节点的主节点，存储到相应槽位上 4.如果客户端当时连接的节点不是将来要存储的分片节点，分片集群会将客户端连接切换至真正存储节点进行数据存储 高可用 在搭建集群时，会为每一个分片的主节点，对应一个从节点，实现slaveof功能，同时当主节点down，实现类似于sentinel的自动failover的功能。 3
