我有一台戴尔 Latitude E6410 笔记本电脑，它会根据环境光线水平改变 lcd 光强度，因此它必须有一些光电管。我怎样才能从这个光电管访问数据？我尝试了不同的谷歌搜索，如照度计、光强度监视器等，但没有找到一个正确的东西。
我想应用此补丁，因此我复制了以“Index: src/options.h”开头并以“+@item”结尾的代码，并将其放入在wget的源代码文件夹中创建的新文件中。然后我做了：
$ patch -p0 < name_of_patch
(Patch is indented 1 space.)
patching file src/options.h
patch: **** malformed patch at line 6: char **excludes; /* List of excluded FTP directories. */
我应该如何应用这个？
这是我创建的文件的内容：
Index: src/options.h
===================================================================
--- src/options.h (revision 2276)
+++ src/options.h (working copy)
@@ -62,6 +62,8 @@
char **excludes; /* List of excluded FTP directories. */
char **includes; /* List of FTP directories to
follow. */
+ int maxsize; /* Maximum file size (kB) */ …我有一个奇怪的情况，在一台服务器上我得到以下结果：
