Don Norman: Simplicity is overblown.

various functions of new products are shouting. Simple is really what they want. Not really. If the journalists really wanted to evaluate the so-called simple products they had listed, they complained that the products lacked the features they thought were "critical". So, when people call for simplicity, what does it really mean? They really want the product, only with a button to operate the best, but also to include all of their favorite features. I used to stroll through a department store i

Is the blockchain ready to meet Fiat? Why are banks so bullish on crypto currencies? __ Block Chain

The central bank will soon see a wave of technological breakthroughs, that is, if the newest members of the utility settlement coin (USC) project have anything to say. The use of secured cryptographic tokens is designed to minimize the role of clearing houses by allowing financial institutions to trade directly with each other, but this work can have a broad impact. Since the collateral associated with these tokens will be held by the central bank, the project is gradually being seen as a step t

Entry-level----black-box testing, white-box testing, manual testing, automated testing, exploratory testing, unit testing, performance testing, database performance, stress testing, security testing, SQL injection, buffer overflow, environmental testing

server side of the database connection request string is also recorded in the System log, This is bound to leak important data. If you follow the black box test, this is the behavior inside the program, the user does not directly manipulate the database connection behavior, so check the system log this aspect of the test is not done, so it will form a hidden bug. Some people compare black-box testing to traditional Chinese medicine by "palpation" to determine whether there is a problem. "Hope":

With the development of the latest route exchange technology, the traditional test content such as route table capacity test, exchange and forwarding capability test, and even oscillating test cannot meet the test requirements of high capacity, high performance, and function-rich route exchange technology. For example: 1) The combination of OSPF and LDP promotes the development of VPLS technology;

Still waiting for the long iOS build process? Try to build and run the iOS app quickly by using the command line

Needless to say, Xcode is a well-known slow-down. What's more, I sometimes find myself too dependent on cocoa Touch's auto-complete function, which is a combination of angels and demons!So I started looking for an alternative process to implement the functionality I needed through the command line. The result is quite confusing: there are some articles that suggest using Xctool and xcodebuild to build Xcode target applications, and then use Ios-sim,simctrl and

For example, capacitors are used in automobiles, but there is no requirement in the measurement content in the teaching materials. You can add experimental items for measuring capacitors. There are many sensors on automobiles, some sensors can be directly measured with A multimeter, so the experimental items of the measurement sen

Mobile Terminal processor composition and baseband chip overview

with the integration of analog baseband and digital baseband more and more inevitable trend, the RF may eventually be fully integrated into the mobile phone baseband chip. The radio frequency section is generally the part of sending and receiving information, and the baseband section is generally the part of data processing. The baseband chip is used to synthesize the incoming baseband signal, or to decode the baseband signal received. The basic frequency is the most important part of the hands
