The "one-piece class" guarantees that only one instantiation object is available and provides a global access portal. "Design Considerations" 1. Blocks all instantiated methods: Private modifier constructor, assignment constructor, assignment copy

i18n internationalization The usual practice is to use the gettext, that is, the use of special keywords in the source code to identify the string will probably be translated, such as@if (model.iscustomerforummoderator) {

P101 refers to the range of disk block sizes [32, 256], butHttp://pclt.sites.yale.edu/blog/2010/03/10/disk-block-size mentions that because there is a minimum unit of read and write (512byte, which now has 4096), So sometimes a buffer is used to
