需要注意的是,s:timestamps中的最后条目是一个极为有用的例子:它会自动地更新任何嵌入式版权声明的年份范围,只要包含它们的文件被编写。
Note that the last entry in s: timestamps is a particularly useful example: it automatically updates the year-range of any embedded copyright notices, whenever a file containing them is written.
最关键的一点是将文件的 BuildAction属性设置为 EmbeddenResource(嵌入式资源)。
What's important is that the BuildAction property of the file be set to Embedded Resource.

在没有存储设备的嵌入式系统中,initrd是永久的根文件系统。
In embedded systems with no mutable storage, the initrd is the permanent root file system.
Groovy模板基本上是具有嵌入式Groovy片段的HTML,与J2EE应用程序中的JSP文件类似。

Heider建议在嵌入式字体中限制字符集以降低SWF文件的总下载时间。
Heider suggests limiting the characters within the embedded fonts to reduce the overall download size of the SWF file.
由于在很多基于Linux的嵌入式系统上没有硬盘,因此initrd也会作为这种系统上的永久根文件系统使用。
Because there is no hard drive in many embedded systems based on Linux, the initrd also serves as the permanent root file system.
最后一点很重要:在将ApacheDerby用作嵌入式数据库时,数据库文件的默认位置是在代码所在的目录中。
This last point is important: When you're using Apache Derby as an embedded database, the default location for the database files is in the directory where your code resides.
initrd对于在嵌入式系统中加载到RAM磁盘里的非持久性根文件系统来说也非常有用。
The initrd is also useful as a non-persistent root file system mounted in a RAM disk for embedded Linux systems.
在嵌入式模式中运行该类还需要 %CLOUDSCAPE%\lib\cs.jar文件。
The %CLOUDSCAPE%\lib\derby.jar file is required to run this class in embedded mode.
今天,B-tree文件系统(BTRFS)可以被用于存储节点,它已经实现了部分必要功能(例如嵌入式完整性)。
Today, the B-tree file system (BTRFS) can be used at the storage nodes, which already implements some of the necessary features (such as embedded integrity).
与嵌入式引导的情况类似,本地磁盘(软盘或CD-ROM)对于引导内核和ramdisk根文件系统来说都不是必需的。
Much like embedded booting scenarios, a local disk (floppy or CD-ROM) isn't necessary to boot a kernel and ramdisk root filesystem.
在构建嵌入式系统时,我们可能希望将initrd映像文件做得尽可能小,这其中有一些技巧需要考虑。
When you're building an embedded system and want the smallest initrd image possible, there are a few tips to consider.
嵌入式SQC程序需要使用PREP命令来编译,该命令将创建绑定文件。
The embedded SQC program needs to be precompiled using the PREP command, which will create the bind file. This bind file needs to be bound with the OPTPROFILE option to the database, for example
要记住我们需要使用这些库来重新编译想在嵌入式系统中重新编译的二进制文件,因此这需要额外再做一些工作(但是这是非常值得的)。
Keep in mind that you'll need to recompile the binaries that you want in your embedded system using these libraries, so some additional work is required (but worth it).
为了简单,我们将展示其中一个方法:通过XML文件映射,映射文件需要被编译成程序集的嵌入式资源。
To keep things simple, we are going to show one way of mapping in this article: we will map to XML files that are compiled as resources of an assembly.
这个方法寻找Derby嵌入式驱动程序的类文件(这个文件必须在CLASSPATH中存在),然后将它装载到JVM中。
This method finds the class file for the Derby embedded driver, which must exist somewhere in your CLASSPATH, then loads it into the JVM.
在某些嵌入式系统中,没有必要提供可更改的文件系统:一个不可更改(immutable)的文件系统已经足够。
In some embedded systems, there's no need to provide a mutable file system: An immutable one will suffice.
在一个没有硬盘的嵌入式环境中,initrd可以是最终的根文件系统,或者也可以通过网络文件系统(NFS)来挂载最终的根文件系统。
In an embedded target without a hard disk, the initrd can be the final root file system, or the final root file system can be mounted via the Network file system (NFS).
