ServerSuperIO is the overall solution for building a system using SuperIO (SIO) and the open-source cross-platform Iot framework serversuperio (SSIO ).
SSIO update
UDP communication mode is added on SSIO. You can download the source code from Github. In the original project, no UDP mode was used for data interaction between remote devices and the Central Station. This short connection communication link is not easy to maintain, mainly reflected in:

1. Background* in the InnoDB storage engine, tables are organized according to the primary key order, which is called the Index Organization table (Index organized table IOT). * in the InnoDB storage engine, each table has a primary key (Primary key), and if a primary key is not defined when the table is created, the InnoDB storage engine chooses the qualifying column in the table or implicitly creates the primary key. 650) this.width=650; "src=" Http

For IoT devices storage can be fully JSON-based, large data volume, often changing the field of the scene is very suitable.3.uuid+json+innodb+partition resolves primary key conflicts that can result from manual synchronization of data, frequent field changes, periodic deletion of data, and retention of the MVCC feature.###############################################This article is from the "dba003" blog, make sure to keep this so

In the IoT platform design process, my middleware needs to process the package from the hardware side, on the other hand, it needs to process the package from the client side, including the Web side and the mobile terminal, etc. So it is very necessary to write a unified CRC authentication.So, at the beginning of the design, what exactly is CRC certification? The so-called CRC authentication, refers to the hardware side or the user before data transmi
Iot security: multiple security vulnerabilities in LED lights
Recently, a foreign security expert found that Zengge's Wi-Fi LED lamp has multiple security vulnerabilities.
ZENGGE is a high-tech company integrating LED Controller Product R D, manufacturing, sales and engineering design, installation and service.
Wi-Fi LED lights are LED Bulbs connected by Wireless WIFI. Such lights can be used as routers, HTTP servers, HTTP proxy servers, and many ot

The storage speed of heap organization tables is faster because sorting is not required. However, to find records that meet certain conditions, you must read all the records for filtering.
At this time, the index will appear to speed up the query. The index is used to sort and store the values of a few specific fields and record the position in the table,
Because the index is ordered, it is easy to query the specific record
