The USB Nic is divided into wireless 3G and wired, and wireless 3G Nic has been implemented by my colleagues. I recently implemented wired Nic. That is, connect to the mid through RJ45 to USB, and the driver will register the ethx network device. What I want to achieve is to operate the network device.
Connectivityservice is a service that manages connections. It manages multiple network types of tracker, such as wifistatetracker and mobiledatastatet
Install and configure FastDFS_v5.05 on CentOS
FastDFS_v5.05 is installed on the new server. There are still many changes compared with FastDFSV3.02. Now we will record the installation and configuration process for your reference. For security considerations, where IP addresses are involved, you can use IP202.98.27.31 at will. When the traffic is low, you can deploy tracker and storage on the same server. Later, you can scale the

You can find a series of profiles and service based on GATT in bluetooth.org.Roles and ResponsibilitiesHere are the roles and responsibilities that apply when an Android device interacts with a BLE device:Center Device (Central) with peripheral devices (peripheral). This also applies to the BLE connection itself. The central device is scanned for advertisenment,peripheral devices to emit advertisement.GATT Server (server) and gat

and is in the application layer of the TCP/IP architecture. According to the BitTorrent protocol, a file publisher will provide a. torrent file, which is a seed file, or "seed", based on the file to be published. The torrent file is essentially a text file that contains tracker information and file information in two parts. Tracker information is mainly used in BT download the address of the
It was ant when I got in touch with my computer and used the software to download it. Then we used the BT tool. Now there are countless software downloads, however, we still need to know about the BitTorrent protocol. This is also the specification for BT seeds and BT downloads. For normal HTTP/FTP downloads, the TCP/IP protocol is used, the BitTorrent protocol is a P2P File Transfer Protocol Based on the TCP/IP protocol, which is at the application layer of the TCP/IP structure. BitTorrent also
I believe that those who have experience in Online downloads will certainly not be unaware of the BitTorrent protocol. This protocol supports what we often call "BT" downloads. Here are some basic information about this protocol. It also includes its specific working principles, hoping to let everyone know about this part.
Common HTTP/FTP downloads use the TCP/IP protocol. BitTorrent is a P2P File Transfer Protocol Based on the TCP/IP protocol, it is in the application layer of the TCP/IP struct
)The audio Listener acts as a microphone-like device. It receives input from any given audio source in the scene and plays the sound through the computer speakers. For most applications, it is most interesting to attach the listener to the camera. If the audio Listener is within the reverb region (Reverb Zone) boundary, the reverb is applied to all audible sounds in the scene. (Professional Edition only) Also, the audio Effect can be applied to the listener and will be applied to all audible sou

After all, the seed file already exists in the form of an attachment file, it also requires server storage and BT Tracker for downloading.

Peer-to-peer in the mind can be said to be the Internet thought/spirit/philosophy is very concentrated embodiment of common participation, transparent open, equal sharing (reminds me of the previous study, is now the crazy speculation of the "centralized" system of cloud computing). There are many applications based on Peer-to-peer technology, including file sharing, instant messaging, collaborative processing, streaming media communication and s

Recently, to improve storage performance (mainly write performance) for small files (around 100KB), the idea of using FASTDFS requires a simple test of its performance.
1. Install Fastdfs
Cd/opt mkdir fastdfs cd fastdfs
git clone https://github.com/happyfish100/fastdfs.git
git clone https://github.com/happyfish100/libfastcommon.git

approaching process of swinging constantly. We can try to remove the restriction.
For as unfamiliar, I would like to explain this: enemy._x + = (dx>=0), Enemyspeed:-enemyspeed), in fact, is equivalent to the following sentence:
if (dx >= 0) {enemy._x = enemy._x + enemyspeed;} else {enemy._x = Enemy._x-enemyspeed;}
This is used to determine the direction of the enemy's movement, according to DX dy positive and negative conditions, to determine which direction to move.
OK, so far, I think it
