Design patterns are an essential knowledge of program promotion, and here's how iOS implements abstract factory design patterns. This article is a look at the OC programming of the Abstract factory this chapter after writing, if you do not understand the principle can look at the book.TestView.h first create a view testview.h// abstractfactory//// Created by du Jia Li on 11/10/14.// Copyright (c) 2014 DuPont.

customers received promotional messages from other vendors who bought the stolen data. In another case, a technical expert working in DuPont copied 400 million dollars worth of trade secrets before leaving the company and then switched to a rival Asian company in DuPont. According to the court's records, he downloaded about 22,000 summaries and 16,700 PDF files using privileged access, which document the

introducing Elon Musk (Elon Musk), chief executive of Space Exploration Technology (SpaceX). He is a great inventor, and he is also very wealthy. He is now developing Tesla electric vehicles. He did take these as a rule. On a TV show, the host asked, "How can you be so creative?" He replied: "Most people want to be creative, but they don't try ... I ask my engineers to be creative. We don't need people with mediocre ideas. He added: "I will work very hard to think of new ideas and think of head

financial class so far, so simply forget how to translate, how simple to call , it's called Roe.I do not think investors are unfamiliar with Roe, but most investors do not fully thoroughly understand Roe, I find many investment books are mentally retarded, the author will simply tell you that Roe is more than 15%, or 20% is good business. Roe itself is not the higher the better, the good or bad of the ROE is not a single figure can be judged, we have to understand its structure, to get a relati

shown.Extended:1.RS-485 is the transmission of data in the form of a negative logical differential signal. +2V~+6V indicates low level,-6v~-2V indicates high level;2. Some pins on the chip can be set to the RX and TX ports of the UART. The use of the DuPont line to connect Rx and TX to the peripherals enables information transfer, such as control of the smart LCD (USART HMI);3.UART turn into COM port need to convert TTL level to RS-232 level, can be

goal is to add an LCD display to the BBB. Although the official have to sell off-the-shelf LCD cape, but buy back plug on the finished, feel too easy, less fun. I just had a hand with a 2.4 "TFT LCD touch screen that I bought when I purchased Alientek STM32 Development Board, I decided to use it to transform. OK, let's start right away. something to prepare. In addition to the LCD, you need to prepare a breadboard, a DuPont line, a number of resistan

David Cutler, the chief designer of VMS and Windows NT, was one of the best kernel developers in Silicon Valley before going to Microsoft in 1988. He has been engaged in operating systems for decades, in the meantime, the experience is like a standard record of Youth struggle in other provinces. Like many predecessors in the computer industry, David Cutler was not born in the computer science class. He took a bachelor's degree in mathematics at the university and focused on physics, enthusiast

Point:1. Serial Port and comport are physical interfaces (hardware ). While TTL, RS-232, RS-485 refers to the level standard (electrical signal ). 2. Generally, only Gnd RX Tx is connected to the device. Do not connect to the VCC or + 3.3v power cord to avoid power supply conflicts with the target device. 3. The pl2303 and cp2102 chips are USB-to-TTL serial ports. They use USB to expand the serial ports (TTL level ). 4, maxcompute chip is TTL level and RS232 level of the dedicated two-way conver

calculate users' voting behavior into a formal search?AlgorithmIn fact, Google's PageRank technology is already an application that judges user behavior. PageRank judges the importance of a webpage based on the number of webpage links, the improvement or deletion of search results can be seen as another signal. According to Cedric Dupont, product manager of Google searchwiki, Google has not determined whether such custom behaviors of users will aff
