Designed as a drop in alternative to PHPUnit's phpunit-mock-objects library, Mockery is easy to integrate with PHPUnit and can operate alongside phpunit-mock-objects without the World ending.",

+很多人比较关心 MongoDB 的适用场景，也有用户在话题里分享了自己的业务场景，比如
+
+案例1
+
+用在应用服务器的日志记录，查找起来比文本灵活，导出也很方便。也是给应用练手，从外围系统开始使用MongoDB。
+用在一些第三方信息的获取或者抓取，因为MongoDB的schema-less，所有格式灵活，不用为了各种格式不一样的信息专门设计统一的格式，极大的减少开发的工作。
+
+案例2
+
+mongodb之前有用过，主要用来存储一些监控数据，No schema 对开发人员来说，真的很方便，增加字段不用改表结构，而且学习成本极低。
+
+案例3
+
+使用MongoDB做了O2O快递应用，·将送快递骑手、快递商家的信息（包含位置信息）存储在 MongoDB，然后通过 MongoDB 的地理位置查询，
+这样很方便的实现了查找附近的商家、骑手等功能，使得快递骑手能就近接单，目前在使用MongoDB 上没遇到啥大的问题，官网的文档比较详细，很给力。
+
+MongoDB做lbs
+
+对于我们的需求，在MongoDB只需一个命令即可得到所需要的结果：
+
+db.runCommand( { geoNear: "places", near: [ 121.4905, 31.2646 ], num:100 })
+查询结果默认将会由近到远排序，而且查询结果也包含目标点对象、距离目标点的距离等信息。
+
+由于geoNear是MongoDB原生支持的查询函数，所以性能上也做到了高度的优化，完全可以应付生产环境的压力。

+简单工厂模式:用来生产同一等级结构中的任意产品。对与增加新的产品，无能为力
+工厂模式 ：用来生产同一等级结构中的固定产品。（支持增加任意产品）
+抽象工厂 ：用来生产不同产品族的全部产品。（对于增加新的产品，无能为力；支持增加产品族）
+以上三种工厂 方法在等级结构和产品族这两个方向上的支持程度不同。所以要根据情况考虑应该使用哪种方法
+适用范围：
+简单工厂模式：
+工厂类负责创建的对象较少，客户只知道传入工厂类的参数，对于如何创建对象不关心。
+工厂方法模式：
+当一个类不知道它所必须创建对象的类或一个类希望由子类来指定它所创建的对象时，当类将创建对象的职责委托给多个帮助子类中得某一个，并且你希望将哪一个帮助子类是代理者这一信息局部化的时候，可以使用工厂方法模式。
+抽象工厂模式：
+一个系统不应当依赖于产品类实例何如被创建，组合和表达的细节，这对于所有形态的工厂模式都是重要的。这个系统有多于一个的产品族，而系统只消费其 中某一产品族。同属于同一个产品族的产品是在一起使用的，这一约束必须在系统的设计中体现出来。系统提供一个产品类的库，所有的产品以同样的接口出现，从 而使客户端不依赖于实现。
+无论是简单工厂模式、工厂模式还是抽象工厂模式，它们本质上都是将不变的部分提取出来，将可变的部分留作接口，以达到最大程度上的复用。究竟用哪种设计模式更适合，这要根据具体的业务需求来决定

+QUICK AND DIRTY
+===============
+
+Execute the following from the src/ directory:
+
+ ./configure # try to figure out all implementation differences
+
+ cd lib # build the basic library that all programs need
+ make # use "gmake" everywhere on BSD/OS systems
+
+ cd ../libfree # continue building the basic library
+ make
+
+ cd ../libroute # only if your system supports 4.4BSD style routing sockets
+ make # only if your system supports 4.4BSD style routing sockets
+
+ cd ../libxti # only if your system supports XTI
+ make # only if your system supports XTI
+
+ cd ../intro # build and test a basic client program
+ make daytimetcpcli
+ ./daytimetcpcli 127.0.0.1
+
+If all that works, you're all set to start compiling individual programs.
+
+Notice that all the source code assumes tabs every 4 columns, not 8.
+
+MORE DETAILS
+============
+
+5. If you need to make any changes to the "unp.h" header, notice that it
+ is a hard link in each directory, so you only need to change it once.
+
+6. Go into the "lib/" directory and type "make". This builds the library
+ "libunp.a" that is required by almost all of the programs. There may
+ be compiler warnings (see NOTES below). This step is where you'll find
+ all of your system's dependencies, and you must just update your cf/
+ files from step 1, rerun "config" and do this step again.
+
+6. Go into the "libfree/" directory and type "make". This adds to the
+ "libunp.a" library. The files in this directory do not #include
+ the "unp.h" header, as people may want to use these functions
+ independent of the book's examples.
+
+8. Once the library is made from steps 5 and 6, you can then go into any
+ of the source code directories and make whatever program you are
+ interested in. Note that the horizontal rules at the beginning and
+ end of each program listing in the book contain the directory name and
+ filename.
+
+ BEWARE: Not all programs in each directory will compile on all systems
+ (e.g., the file src/advio/recvfromflags.c will not compile unless your
+ system supports the IP_RECVDSTADDR socket option). Also, not all files
+ in each directory are included in the book. Beware of any files with
+ "test" in the filename: they are probably a quick test program that I
+ wrote to check something, and may or may not work.
+
+NOTES
+-----
+
+- Many systems do not have correct function prototypes for the socket
+ functions, and this can cause many warnings during compilation.
+ For example, Solaris 2.5 omits the "const" from the 2nd argument
+ to connect(). Lots of systems use "int" for the length of socket
+ address structures, while Posix.1g specifies "size_t". Lots of
+ systems still have the pointer argument to [sg]etsockopt() as a
+ "char *" instead of a "void *", and this also causes warnings.
+
+- SunOS 4.1.x: If you are using Sun's acc compiler, you need to run
+ the configure program as
+
+ CC=acc CFLAGS=-w CPPFLAGS=-w ./configure
+
+ Failure to do this results in numerous system headers ()
+ not being found during configuration, causing compile errors later.
+
+- If your system supports IPv6 and you want to run the examples in the
+ book using hostnames, you must install the latest BIND release. You
+ can get it from ftp://ftp.vix.com/pub/bind/release. All you need from
+ this release is a resolver library that you should then add to the
+ LDLIBS and LDLIBS_THREADS lines.
+
+- IPv6 support is still in its infancy. There may be differences
+ between the IPv6 sockets API specifications and what the vendor
+ provides. This may require hand tweaking, but should get better
+ over time.
+
+- If your system supports an older draft of the Posix pthreads standard,
+ but configure detects the support of pthreads, you will have to disable
+ this by hand. Digital Unix V3.2C has this problem, for example, as it
+ supports draft 4, not the final draft.
+
+ To fix this, remove wrappthread.o from LIB_OBJS in "Make.defines" and
+ don't try to build and run any of the threads programs.
+
+COMMON DIFFERENCES
+------------------
+
+These are the common differences that I see in various headers that are
+not "yet" at the level of Posix.1g or X/Open XNS Issue 5.
+
+- getsockopt() and setsockopt(): 5th argument is not correct type.
+
+- t_bind(): second argument is missing "const".
+
+- t_connect(): second argument is missing "const".
+
+- t_open(): first argument is missing "const".
+
+- t_optmsmg(): second argument is missing "const".
+
+- If your defines the members of the t_opthdr{} as longs,
+ instead of t_uscalar_t, some of the printf formats of these value
+ might generate warnings from your compiler, since you are printing
+ a long without a corresponding long format specifier.
