Publish SubscriptionA simple example of a publish subscription is a switch that simultaneously switches several bulbs in parallel (in different rooms), and when triggered, a few bulbs are given instructions and then perform the glowing behavior.// 使用pubsubz实现var testSubscriber = function(data ){ console.log(data );};var testSubscription = pubsubz.subscribe( ‘example‘, testSubscriber );pubsubz.publish( ‘exa

As a smart hardware and smart home enthusiasts, I understand that the current smart lamp mainstream technology has Bluetooth, ZigBee, WiFi and so on, so bought a representative of each technology products, and made some trial summary. Summary of the technical, if there is no understanding of technical terms, interested readers can search on the web to understand.First look at the value of Yan. is a group of light bulbs, from left to right, followed by
Some time ago, the ceiling lamp in the living room was broken, and a light bulb was not on (a total of two bulbs, 55 W incandescent ).
No way. As a man, this kind of work can only be done by yourself.
I thought it was only the light bulb A that broke down. I pressed the light bulb to the socket of A, but the result was still not bright.
Put the light bulb A on another tube plug-in, bright, there is no problem with the light bulb.
It can only be the pr

Is it worthwhile for users to buy at a higher price?These so-called smart home practicality is obviously insufficient, onlookers see also can, buy use on some chicken. In fact, good imagination and real life needs are very different, like everyone wants to become a billionaire can be food and clothing without worry, but in reality only to do an ordinary staff can eat and drink; many people imagine life in the smart home environment of c
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

For turtles that do not let them hibernate, You Can Take warm feeding measures during winter cooling, if it is a land turtle, ordinary desk lamp can be used with ordinary incandescent bulbs or special crawling animal bulbs (including ultraviolet), crawling animal heating blanket, heating stone, or put electric heating in the room, but b
communicate with each other two times, and then send people to pick up the goods respectively. But one day the person who sent the goods was drunk and went to the light bulb to ask for the lamp, the person who made the lamp again took the light bulb, and the error occurred. Later, the two men jointly started a light factory with two production lines. This factory can make both bulbs and tubes at the same time, so I only need to negotiate with this fa

A person is responsible for switching bulbs in the corridor. There are n bulbs (numbered from 1 to n) in the corridor, and he will go back and forth to N;
At the beginning of the I-th step, he will switch the light bulb whose number can be divisible by I;
Now we need to figure out whether the last light bulb (number N) is bright or dark after N trips.
Analysis: mathematics. This question is the parity of th

Then I realized that they didn't really come because of me. That day is my birthday, but I know who is the superstar of the emperor at the banquet.For several days, the room was crowded with helpers from Dad.

Fault analysis: The author suspected that the auxiliary power supply circuit of the video card has short circuit. But there is no multimeter on hand and no second graphics card, in order to verify this inference, the author used small bulbs, batteries and wire sel
11. Next, let's take a look at how the surface works. Click on the top level of the layer Order and the dialog on the right becomes the Surface Options dialog box (Figure 12). This layer controls the specific details of the texture, combining the shading layer to control the lighting effect. Its control options have four items, respectively, for roughness--roughness, brilliance--luster, metallicity--metal texture, graininess--granules.

Understanding the door, we can do some practical applications, the main purpose of the computer is calculated, and the door can be used for calculation, so it can be said that the computer is composed of a variety of different doors. The next thing we do is make a binary adder, because if you make an adder, you can extend it to subtraction, multiplication, division. And how do we implement the adder? We only use some of the most common and somewhat backward parts: switches,
(mutex)
puts "A:I have CRI Tical Section again! I rule! "
}
}
Puts "(later, back at the ranch ...)"
b = thread.new {
mutex.synchronize {
puts "B:now I am critical, but am done with CV"
cv.signal
puts " B:i am still critical, finishing up "
}
a.join
b.join
This will produce the following results:
A:I have critical section, but'll wait for CV
(later, back at the ranch ...)
B:now I am Critical, but am done with CV
b:i
