Stored procedures are compiled only at creation time, and each subsequent execution of the stored procedure does not need to be recompiled, while the general SQL statements are compiled once per execution, so the stored procedure is usedCan improve database execut

Today to the bookstore to see a book called "C # Internet of Things Programming fundamentals " books, interested in the internet of things I grabbed to see, the book is the project is the host computer development projects, simpler, if the Internet of things development is just this, it seems that I do IoT development is more than enough. I looked at this book for more than 10 minutes, and the technical mishap made me face it. This book says using WPF

In the book "evolution of the Internet", we propose that "the future functions and structure of the Internet will be highly similar to that of the human brain, and the virtual perception of the Internet, virtual movement, virtual hub, and virtual memory neural system will be available"And draw a structure of the Internet virtual brain. Based on this point of view, we try to analyze the relationships between the four most popular Internet concepts ----------- big data, cloud computing,

Comparison of four wireless technologies: Who is more suitable for the IOT field? It is predicted that about 2020 devices will be connected via wireless communication by 50 billion. According to data from the GSM alliance, mobile handheld computers and personal computers only account for 1/4 of the total, while the rest are self-interconnected devices that use non-user interaction to communicate with other machines. At present, our Internet is rapidly

opportunities and development space, while some security issues surfaced, more and more physical devices connected to the Internet of things, coupled with the user's lack of security awareness, hackers can easily hijack physical devices into zombies, and manipulate these devices to launch a DDoS attack. So what do equipment manufacturers and IDC operators need to do to deal with such DDoS attacks?First device manufacturers need to add secure program settings in the terminal, now hackers can eas

IOT command (based on sip) client API design for java, iotsipThe Iot Device Control we implement is implemented by extending the sip protocol. Because pjsip is implemented based on pjsip, while pjsip uses C Programming, how to make the business layer (android end, java) easier to use the provided command API is the focus, the original method is to encapsulate (C ---> jni ---> java) from the underlying c, wh

Tags: Reading Notes microprocessor Network Management Communication Technology System Integration I recently read the book "IP-based Iot architecture, technology, and application" and recorded my reading notes here. 1.

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:

At the end of MWC not long ago, Ubuntu not only showed a brand new development environment for tablets, mobile phones, and cloud services, it also confirms with companies and startups focused on using snappyUbuntuCore for Iot development. These partners are from wireless base station, smart city, drones and other fields, and will build an Airbnb-like future with Ubuntu. SnappyUbuntuCore has a great potential for development (http://www.ubuntu.com/ In

The advent of the new WiFi technology is more suitable for smart home and Iot According to TheVerge, the US technology website, WiFi seems to have connected most devices in the consumer's home. Why not connect Smart appliances through it? Although such an idea seems to be taken for granted, in fact, most network-connected device manufacturers have been reluctant to use WiFi, mainly because WiFi consumes too much power, so for many cheap micro-devices

Data standards are the core of Iot Big integrated applications The essence of Iot is M2M, that is, communication between machines. Here we talk about machine in a broad sense. It can be as small as a "Smart Dust ", for example, an RFID chip or a biosensor embedded in the human body is as big as a high-speed train or a space shuttle, m2M can be a one-to-one or multiple-to-one connection to all ends of a clo
