Fourier series:
The waveform of any period can be decomposed into several sine waves, the frequencies of which are integral times. The frequencies of other positive line waves in the series are integral
The win8 steps logger uses the following tutorial:
1. First, we press the WIN8 computer keyboard on the WIN+C key combination to open the computer's Charm menu, in the Open menu, we click on the selection, we click to select the search options.
If you want to check which Web pages a computer user has recently seen, use the "browsinghistoryview" handy gadget. It can capture the browser's browsing history directly, depending on the date you specify, or in the last few hours/days, supporting
Perfect API design
Good API design specifications
Why is good application programming interface (API) design so difficult? Just throw together a few classes with a few basic methods on them and call it done.
You cocould do this, if you don't mind other developers cursing you-and referencing your API as an anti-pattern. How can this be avoided? Aim for perfection with API design. Yes, perfection.
Why is it always difficult to design well-designed application interfaces (APIS)? interfaces are not

Many may be unfamiliar with mythtv, because it is mainly for the home entertainment system in Linux. The original purpose of its designers is as follows:
We like to think of mythtv as the ultimate digital video recorder and home media center hub. Think of it as a free and open source alternative to Windows Media Center or tivo.
It started out in 2002 as a way for Isaac Richard to produce a better TV-viewi
Joost is a peer-to-peer network TV written by Skype and Kazaa writers, and you can receive TV shows online via Joost. At this point, there is not much difference between the Joost and the domestic PPLive, PPStream, and qqlive.
Unlike PPLive, Joost is not only a free TV, but more like a home video recorder, you can choose any program to control the show, and Joost is a community where you can communicate with other users watching the same program while

A recorder is an object that developers often interact. The main APIs describe what we want to record.
For example, a recorder can categorize requests to send a message without worrying about how they are sent.

It can be installed on the observer computer, while the manager is a component for later data analysis.
The usage relationship of the three major components is: after the

ITunes and TiVo also prove the core principles of many other Web 2.0. They are not web apps in nature, but they take advantage of the power of the Web platform to make it seamless and almost as part of their underlying structure. Data mana
I. Introduction to log4j Components

These three components work together to enable developers to record information based on information categories and levels, andDuring operation, the log storage location has been controlled by the information record method.

Keyboard security problems and hazardsWith various hacker technologies, hackers can remotely control the installation of keyboard recording programs on users' computers. These tools, known as keyboard recorders, can record all information that users enter from the keyboard. As hacking technologies are increasingly open to the public, even beginners can easily use these tools, resulting in greater harm to users. Once the user's computer is installed with a keyboard
In those years, the machine has already entered the home of an ordinary user. The old man Bill of Microsoft is also anxious. No, "to make it easier for Windows users to use the recorder", he immediately integrated the CD burning function in Windows XP. After careful consideration, this function is very practical. When you are eager to burn a disk and cannot find a burning program, you can feel the beauty of the built-in burning function in windows. No
