What this means is that most vertical applications are a mere recompilation away from running equally well on linux , freebsd , sunos , irix , aix , or indeed on mac os x ; in some cases even this step is not necessary , since abis application binary interfaces support foreign binaries 这意味着什么呢，大部分垂直应用程序只需要重新编译就可以很好地运行于linux 、 freebsd 、 sunos 、 irix 、 aix ，当然也可以运行于mac os x ；有时连这个步骤都不是必须的，因为abi （应用程序二进制接口）支持外来的二进制文件。
As has been shown in other languages , the combination of a source editor and repl makes a powerful tool . this installment hopefully has identified and demonstrated a major tool to let you interactively evaluate expressions and statements in java programs without getting bogged down in recompilation - the " read - eval - print - loop " or repl 希望本部分已经指出并演示了一种主要工具，它能让您交互地对java程序中的表达式和语句进行评价，而不陷入重编译的泥沼这种工具就是“读取-评价-打印-循环”即repl工具。
