USB海量存储设备类规范包括四个独立的子类规范：(ATA command的那个没有) ①USB Mass Storgage Class Control/Bulk/Interrupt(CBI)Transport ②USB Mass Storage Class Bulk-Only Transport ③USB Mass Storage Class ATA Command Block ④USB Mass Stroage Class UFI Command Specification。 前两个子规范定义了数据/命令/状态在USB上的传输方法。 Bulk-Only传输规范仅仅使用Bulk端点传送数据/命令/状态， CBI传输规范则使用Control/Bulk/Interrupt三种类型的端点进行数据/命令/状态传送。 后两个子规范定义了对存储介质的操作命令。 ATA 命令规范用于硬盘。 UFI命令规范是针对USB移动存储而制定的，实际上UFI命令格式是基于SFF-8070i和SCSI-2规范，总共定义了19个12字节长度的操作命令。

A complete set of bit banged, software driven I2C routines I created for any PIC device - and they work!! These functions are single master only functions, and are ideal for communicating with things like EEPROMs, LCD Drivers, ADC Converters etc

The Staged Event-Driven Architecture (SEDA) is a new design for building scalable Internet services. SEDA has three major goals: To support massive concurrency, on the order of tens of thousands of clients per node To exhibit robust performance under wide variations in load and, To simplify the design of complex Internet services. SEDA decomposes a complex, event-driven application into a set of stages connected by queues. This design avoids the high overhead associated with thread-based concurrency models, and decouples event and thread scheduling from application logic. SEDA enables services to be well-conditioned to load, preventing resources from being overcommitted when demand exceeds service capacity. Decomposing services into a set of stages also enables modularity and code reuse, as well as the development of debugging tools for complex event-driven applications.
