Baidu | ranking | search Engine | chinese For more than half a month, I pay more attention to my blog in Baidu rankings. The reason is, of course, I am ready to optimize the Chinese website, and Baidu so far is the largest market share of the Chinese search engine.Previously because they are doing English websites, so did not pay attention to Baidu and other Chinese search engine. For more than half a month of observation, there are a few small tips t

We're going to go ahead. ROS Learning Series--using URDF to create a robot model in Rviz one of the 3D observation link uses continue to create a two-wheeled trolley with four wheels to rotate. A set of joint that can rotate 1. Change the joint type to "continuous" so front_left relative base_link is a rotating device 2. The position of rotation is defined by the origin, which defines the new origin of the Tyer_front_left, which is the origin of t

Previously there have been a number of high man found SEO three tags in the keywrods to optimize the ranking of the site is almost equal to 0 of the impact. I do not repeat the old examples.

Small station is the general enterprise station, optimization has been a friend for a year, basically still stable. A few days ago that Mister and I

Some object-oriented programming methods provide the ability to build complex network interconnection between objects. When objects are connected together, they can provide services and information to each other. Generally speaking, when the state of an object changes, you still need the object to communicate with each other. But for a variety of reasons, you may not want to make big changes to your code because of changes in your code environment. Perhaps, you just want to improve the communic

The sandbox effect of the Web site is introduced by the most important search engine Google, and the new site usually goes into Google's sandbox, in the sandbox, which is usually an observation period for the search engine on the new site, so the lower the new site rankings.

The camera can also be an observer, and the simplest example is the soul. The player moves the role forward, backward, and jump. The displayed world (that is, the background behind) will not stop changing. It is actually caused by changes in the camera's observation point (angle of view. Maybe the game world (b

Obj-c Programming 17: key value observation (KVO) After finishing the previous article on KVC, I can't help but talk about its application KVO (Key-Value Observing. KVO is similar to the hook function in ruby. When an object property changes, the observer can track the changes and then observe or modify the changes, this is done through the callback function registered by the callback observer. To use key-value ob
