Socket disconnection Detection heartbeat detection

off.In fact, to determine the drop line, only need to send or recv, if the result is zero, the drop line. However, under long connections, there may be no data exchange for a long time. Theoretically, this connection is always connected, but in reality, it is difficult to know what is wrong with the intermediate node. What's more, some nodes (firewalls) will automatically disconnect a certain amount of time without data interaction. At this time, we need our heartbeat packs to maintain long con

Principle and application of accelerometer-mobile phone rollover, weightlessness detection, motion detection, position recognition

This paper introduces the characteristic principle and application scenario of the-LIS3DH accelerometer sensor for wearable devices. ST's LIS3DH is widely used in smart wearable products such as smart hand loops and smart step shoes.LIS3DH has two ways of working, one of which is that it has built-in algorithms to handle common scenarios such as standstill detection, motion detection, screen flipping, weigh

Tmg https detection for virus camouflage detection

We learned how to use TMG to protect Exchange 2010 Server with Forefront TMG. This article introduces how to detect tmg https to prevent viruses and trojans from intruding into the server in disguise. 1. Introduction to tmg https Inspection Tmg https Inspection (HTTPS detection) can prevent internal clients from accessing some illegal HTTPS websites. In general, it is to prevent clients from establishing SSL connections directly with external servers

Target Detection program Development (IV.)--Target detection

Met a good "OpenCV introductory tutorial" http://www.opencv.org.cn/forum.php?mod=viewthreadtid=33549 An introduction to the operations that contain the matrix classes and their memory management And the operation of reading and writing images and videos. An example #include Detectmultiscale This method is very slow,,, scan again I use 50x50 only scan 1 times have to 1s time, basically not reach the application requirements, should consider the actual situation of the problem, self-rewriting

PHP Detection Mobile Detection Use instance _php tutorial

At present, a website has more than one version is very normal, such as the PC version, 3G version, mobile version and so on. Depending on the browsing device we need to be directed to different versions. Not only that, we sometimes need to load different CSS depending on the client, so we need to be able to detect the browsing device so that we need to use the "mobile detection" class library. "Mobile Detection

How to develop an anomaly detection system: How to evaluate an anomaly detection algorithm

Evaluating the importance of an anomaly detection algorithm using numerical valuesIt is important to use the real-number evaluation method , when you use an algorithm to develop a specific machine learning application, you often need to make a lot of decisions, such as the choice of what characteristics and so on, if you can find how to evaluate the algorithm, directly return a real number to tell you the good or bad of the algorithm, That makes it ea

Browser Feature Detection (2)-General event detection

Document directory Basic Solution Some tag-specific events DOM pollution Firefox BUG Firefox BUG persists Add Cache Mutation Event DOMContentLoaded Related Resources Event detection is used to detect whether an event exists (available) in different browsers.

Browser Feature Detection (2)-General event detection

Event detection is used to detect whether an event exists (available) in different browsers. This is also very important during Javascript writing. For example, the mouseenter/mouseleave event is practical, but not all browsers provide standard support, so you need to manually simulate it yourself, that is: Function addEvent (element, name, handler) {if (name = 'mouseenter '! HasEvent (name, element) {// simulate a mouseenter event by other means} //

Target detection algorithm based on deep learning: a common target detection algorithm for ssd--

from:73439202Problem Introduction:At present, the common target detection algorithm, such as faster R-CNN, has the disadvantage of slow speed. The SSD method proposed in this paper not only improves the speed, but also improves the accuracy.SSD:The core idea of this paper:The main contribution of this paper:1. The SSD target detection method is proposed, which is faster than the fastest YOLO in speed, and c
