Recently feel the use of mobile hard disk backup Mac computer is very inconvenient, because to take out the mobile hard disk, but also plug in the computer backup, looked at airport, but the price is too expensive, and can only be used for Mac backup and can not be used for other samba services, etc., feel less cost-effective, So I'm going to do a timemacheine and samba service, the Timemacheine service is used primarily for Mac backups, and samba is

XYZ has only two types of aircraft, model A and model B. Both of them fly exactly in the same way. Therefore, XYZ is designed as follows hierarchy (inheritance system ):

error in any way they think appropriate. If a class does not want to do anything special, you can use the default error processing function provided in the shape class. That is to say, the shape: Error Declaration tells the subclass designer, "you must support the error function. But if you do not want to write your own version, you can use the default version in the shape class. "
In fact, it is dangerous to provide function declarations and default implementations for simple virtual functions
Plane hierarchy of XYZ airlines. XYZ has only two types of aircraft, A and B, and the flight modes of the two types are the same. Therefore, XYZ has designed such a hierarchy:

systems in the past often cannot be installed on partitions outside the primary partition, so the primary partition is labeled "Specifically for installing the operating system".We already know that the sub-table area in the MBR can only hold 4 partitions (that is, 4 primary partitions), how the system divides more than 4 partitions?A straightforward and simple idea is to subdivide one of the main partitions and derive a two-level partition table . Yes, the primary partition that is used for tw

these types can be used as keys in the dictionary. Enumeration members with unassociated values (see enumeration) can also be hashed by default.
Dictionary literal statement
We can use dictionary literal statements to construct a dictionary. They have similar syntax as the array literal statements we just introduced. A dictionary literal statement is a simple statement that defines a dictionary set with one or more key-value pairs.
A key-value pair is a combination of a key and a value. In a

Now, assuming that XYZ's wealth has increased, it is decided to introduce a new model, Model C. Model C is different from model A and model B in some aspects. In particular, its flight is different.
Programmers at XYZ added the class of Model C to hierarchy (inheritance system), but they forgot to redefine the fly function as they rushed to put new models into service:
Class modelc: Public airplane {
... // No Fly function is declared};
Therefore, in
-value pair is a combination of a key and a value. In the dictionary literal, the keys and values in each pair of key-value pairs are separated by a colon, and the key-value pairs are separated by commas, and these key-value pairs are wrapped with a pair of parentheses:[Key 1:value 1, key 2:value 2, key 3:value 3]The following example creates a dictionary that stores the name of an international airport, in which the key is the three-letter IATA code,

Everyone seems to be very concerned about weather forecasts. Of course, obtaining accurate weather forecasts is very useful for your travel plans and other activities. Weather forecast information can be obtained in many places, such as webpages, most smartphones or tablets. Now you can use the "wether" tool on Raspberry Pi to obtain the weather forecast information through command line."Weather" can be installed from Raspberry Pi's official sources:
