Many languages, including English, use the immersion character (accented character). Because these characters are not part of the ASCII character set, it is difficult to write code that uses these characters without looking at the Unicode value or using the Unicode editor and turning it into a known character set.
Oracle9i introduces the COMPOSE function, which accepts a string of Unicode characters and rules its text. This means that it can a
In the previous part, " Run the ASPDOTNETCOREMVC program on Docker-part4: Load Balancing ", We have several more complex steps on the Docker platform to achieve the load balance of the website program, configuration steps are more. If the actual site is less, the overall architecture is relatively simple case, this does not have much problem, if the application of more time, will be prone to error. At this point we may think of writing scripts to automate, of course, this is possible. Docker, ho
One pattern in functional programming is to implement a combination function by combining functions of multiple functions. A tool library that generally supports functional programming implements this pattern, which is commonly referred to as compose and pipe. For example, the Ramda tool Library, known as the functional type.
const R = require('ramda');function inc (num) { return ++num;}const fun1 = R.compose(Math.abs, inc, Math.pow)const fun2 = R.p

Physical security is from the hardware perspective, primarily involving the protection of IBM I data storage media; Logon security is user-centric, restricting who accesses IBM I and what to do after logging in; Resource secur
