為了在工業生產及過程控制中準確測量溫度，設計了一種基于低功耗MSP430單片機的數字溫度計。整個系統通過單片機MSP430F1121A控制DS18B20讀取溫度，采用數碼管顯示，溫度傳感器DS18B20與單片機之間通過串口進行數據傳輸。MSP430系列單片機具有超低功耗，且外圍的整合性高，DS18B20只需一個端口即可實現數據通信，連接方便。通過多次實驗證明，該系統的測試結果與實際環境溫度一致，除了具有接口電路簡單、測量精度高、誤差小、可靠性高等特點外，其低成本、低功耗的特點使其擁有更廣闊的應用前景。
Abstract:
In order to obtain accurate measuring temperature in industrial production and process control， a digital thermometer based on MSP430 MCU is designed. The system uses MSP430F1121A MCU to control DS18B20， and gets the temperature data， which is displayed on the LED. The temperature sensor DS18B20 and MCU transmit data through serial communication. MSP430 series has ultra-low power and high integration， DS18B20 only needs one port to achieve data communication. Through many experimental results prove， this system is consistent with actual environment temperature. The system has characteristics of interface circuit simple， high measuring accuracy， minor error， high reliability， besides， the characteristics of low cost and low power make it having vaster application prospect.
About:
Paco (pacKAGE oRGANIZER) is a simple, yet powerful tool to aid package management when installing programs from source code. It uses the LD_PRELOAD method to track package installations, and provides various options to keep the installed software organized. It s mainly a command line application but it has also an optional GTKMM interface.
Release focus: minor bugfixes
Changes:
Libpaco-log has been rewritten in C. This prevents a glibc installation failure when building LFS in chapter 6. The option -x|--expand has been removed. Several bugs have been fixed in paco, gpaco, and rpm2paco.

About:
hamsterdb is a database engine written in ANSI C. It supports a B+Tree index structure, uses memory mapped I/O (if available), supports cursors, and can create in-memory databases.
Release focus: Major feature enhancements
Changes:
This release comes with many changes and new features. It can manage multiple databases in one file. A new flag (HAM_LOCK_EXCLUSIVE) places an exclusive lock on the file. hamsterdb was ported to Windows CE, and the Solution file for Visual Studio 2005 now supports builds for x64. Several minor bugs were fixed, performance was improved, and small API changes occurred. Pre-built libraries for Windows (32-bit and 64-bit) are available for download.

xl2tpd a Layer 2 Tunneling Protocol (L2TP) daemon. It supports IPsec SA reference tracking, which enables the IPsec stacks to support multiple l2tp clients behind the same NAT router and multiple l2tp clients on the same internal IP address. It is a fork of "l2tpd".
Release focus: minor feature enhancements
Changes:
Support for passwordfd, a workaround for some Cisco routers, and extended logging.

μC/OS-II Goals
Probably the most important goal of μC/OS-II was to make it backward compatible with μC/OS (at least from an
application’s standpoint). A μC/OS port might need to be modified to work with μC/OS-II but at least, the application
code should require only minor changes (if any). Also, because μC/OS-II is based on the same core as μC/OS, it is just
as reliable. I added conditional compilation to allow you to further reduce the amount of RAM (i.e. data space) needed
by μC/OS-II. This is especially useful when you have resource limited products. I also added the feature described in
the previous section and cleaned up the code.
Where the book is concerned, I wanted to clarify some of the concepts described in the first edition and provide
additional explanations about how μC/OS-II works. I had numerous requests about doing a chapter on how to port
μC/OS and thus, such a chapter has been included in this book for μC/OS-II.
This a sample Plug and Play filter driver that provides WMI data blocks. Typically, driver writers will copy the sample code into their own driver and make any minor modifications so that the WMI data blocks are always available when the driver is loaded. Alternatively, WmiSamp can be left as a filter driver if WMI data blocks should only be made available when the filter driver is loaded.
