Note that this means, unlike vowels, intervening H and W characters do not act as a barrier to combining runs of letters with the same code.
请注意：这意味着，与元音不同同，插在中间的字符 H 和 W 不会对组合相同代码的字母形成障碍。
In one sense, you're still depending on the word of others; open source does remove a major barrier by giving you the program code but that's only part of the puzzle.
从某种意义上，你依然要依赖其它人。开源通过给你程序源代码确实移除了一个主要的障碍，但这只是难题的一部分。
While this is easy to encapsulate, it's still a portability barrier because it requires you to rewrite your lookup and calling code, effectively tying your application to the JBoss platform.
虽然这样的代码易于封装，但是在可移植性上仍然存在障碍，因为它需要重新编写查找和调用代码，这实际上将应用程序捆绑到了JBoss平台上。
