Some things are recorded and will be used again soon.1. Updating complex nested objects from MongoDB to SOLRRecently using Mongo-connector to open MongoDB with SOLR, for simple JSON, update is no problem. The problem we have this time is that if the value of one field in JSON is an array type, or if there is an object nested within it, then what is the whole thing? For example, we insert such a shipment in MongoDB:{ "_id": "555df36ec6cd08ea807a4324

This is a simple robot projection game, mainly to be familiar with some things of the physics engine. You can think of it as a robot shot, even though it is a parabolic, but not a basketball but a bullet, faster.The game is the player chooses the robot, the mobile robot arm aims at the basket frame, then launches the bullet. If the bullet falls into the basket, the score is scored. The game ends when the bullet runs out or the time runs out.The main g

Motivation: When developing a real-time system, you often need to create a set of objects to map remote devices.This set of objects displays the status and notifications of remote devices.This group of objects is used to encapsulate the operations and management of remote devices. However, before the image remote device provides the above features.You also need to provide the function of exploring remote devices to create a list of remote devices.In this way, we can provide complete services.
These three words are often seen in various books and documents. projection is the most used, coordinate system is the second, and spatialreference is the last.
