Pattern matching using extractor:
When an instance of a class is followed by parentheses using a list of 0 or more parameters, the compiler invokes the applied method on that instance. We can define both objects and classes.
As mentioned above, the purpose of the Unapply method is to extract a particular value from what we are looking for. It operates in the opposite way as apply. An extract object that compares the Unapply method in a matching statem

During embedded development, we compile a *. s file and finally generate the binfile. The compilation command is roughly as follows:
Cc = arm-softfloat-Linux-GNU-gcc
LD = arm-softfloat-Linux-GNU-LD
Objcopy = arm-softfloat-Linux-GNU-objcopy
$ (CC)-G $ (cflag)-C boot. s # first generate the boot. s file to boot. o

In embedded development, compiler-generated target files are generally. hex files.Why to convert, direct use of hex file not, but I have been in the development process is directly generated hex files, and then download, also did not see an error.When you are not sure of the format of the hex and bin files, it may be a problem for your small partners. The reason for the conversion is that the data records (

A Linux Installation File
Common Linux installation methods include tar, zip, GZ, rpm, Deb, and bin. We can simply divide it into three categories,

Second, corresponding to Deb and RPM with management tools. Generally, such installation files can be simply installed through a thi
