Poke me!0x02 RequirementsBefore using Metasploit, we have to ensure that our equipment meets the following requirements, including hardware and software.Hardware: Make sure that your computer or VM meets the requirements below.Hard disk space: If you want to use Metasploit, first you have to make sure you have 10GB of storage space. Because Metasploit will use some large files. When partitioning, make sure that you are not partitioning with the FAT32
to abide by the protocol at the lower level. For the higher level, the Protocol applies to network applications and management. Therefore, the Protocol is essentially an agreement, and it is a formal agreement. For example, IP is the layer-3 protocol of OSI/RM.
The standard has a wider scope. It includes not only written conventions, but also all uniformly executed rules on the network. Therefore, standards are sometimes referred to as norms or rules. For example, IEEE 802.3u is a fast Ethernet

between MAC address and switch port, so in the next step into the switch Ethernet frame, read the destination MAC address, find the corresponding port, Exchange. All the steps are done on the second level, the switch does not open the third layer, so it can be realized through hardware, and the exchange is fast.
Early Ethernet switching uses Half-duplex mode, and the CSMA/CD (Carrier Sense Multi access/collision Detect) Conflict detection mechanism must be enabled. In order to avoid two hosts

Order:Recently I Just Wanted To write a map editor similar to rmxp. The first problem I encountered was the issue of creating an automatic map component. Honestly, I don't know what this thing is called (especially in English). I only know that rmxp is an automatic map component, and the map editor of warcraft also uses this technology, however, I still cannot
boundary, the Unit coordinate is a convenient measurement method. When the size changes, you do not need to adjust it again. The Unit coordinates are used in texture coordinate systems such as OpenGL, and the Unit coordinates are also used in Core Animation.

In JAVA hibernate, it can be understood that object operations are performed, however, most php orm uses chained operations (in fact, splicing strings). The last operation will execute the statement, which is equivalent to spelling in the code... ORM (Object relationship ing) is a ing between objects in the memory and relational data.
