The PCA9541 is a 2-to-1 I2C-bus mAster selector designed for high reliability dual mAsterI2C-bus applications where system operation is required, even when one mAster fails orthe controller card is removed for maintenance. The two mAsters (for example, primaryand back-up) are located on separate I2C-buses that connect to the same downstreamI2C-bus slave devices. I2C-bus commands are sent by either I2C-bus mAster and are usedto select one mAster at a time. Either mAster at any time can gain control of the slavedevices if the other mAster is disabled or removed from the system. The failed mAster isisolated from the system and will not affect communication between the on-line mAsterand the slave devices on the downstream I2C-bus.

Abstract: Designers who must interface 1-Wire temperature sensors with Xilinx field-programmable gate arrays(FPGAs) can use this reference design to drive a DS28EA00 1-Wire slave device. The downloadable softwarementioned in this document can also be used as a starting point to connect other 1-Wire slave devices. The systemimplements a 1-Wire mAster connected to a UART and outputs temperature to a PC from the DS28EA00 temperaturesensor. In addition, high/low alarm outputs are displayed from the DS28EA00 PIO pins using LEDs.

sheerdns is a mAster DNS server whose zone records are stored on a One-Record-Per-File bases. Because of this, it is the simplest of any DNS to configure, the easiest to update, and the most efficient for networks that experience a lot of updates (for example mAster servers for dynamic IP address ranges). You never have to restart it; any updates are available immediately without having to notify the sheerdns process. 来源: http://freshmeat.net/projects/sheerdns/?topic_id=149 sheerdns是一个主DNS服务器，它的域记录保存在一个One-Record-Per-File（每文件一个记录）的库中。因此，它是最简单的DNS配制，最容易更新，对于有大量更新的网络（如动态IP地址范围的主服务器）来说它是最高效的。你不必重新启动它，任何更新不用通知对应DNS进程就可以立即生效。
