conventions

问题 If you ever wonder in what order to enter your CSS attributes like border , padding , font-family , etc. Two common approaches seem to be Alphabetical and Box Model. (See: Conventional Order of CSS properties) This not to be confused with selectors ( #id , .class , :hover , tagname ) in which case the order matters very much. The Alphabetical option does not make much sense to me. For one thing it sticks padding and line-height in the middle of width and height or left and top . I will post a

问题 Yes I know, there have been a number of questions (see this one, for example) regarding the usage of & vs. && in R, but I have not found one that specifically answers my question. As I understand the differences, & does element-wise, vectorised comparison, much like the other arithmetic operations. It hence returns a logical vector that has length > 1 if both arguments have length > 1. && compares the first elements of both vectors and always returns a result of length 1. Moreover, it does

问题 Unsure of the Python convention for type hinting instance variables - I've been doing them within the __init__ constructor arguments like seen here: class LoggedVar(Generic[T]): def __init__(self, value: T, name: str, logger: Logger) -> None: self.name = name self.logger = logger self.value = value` link to above code snippet: https://docs.python.org/3/library/typing.html#user-defined-generic-types But I also see the PEP conventions of annotating instance variables as such(snippet below) and

问题 In node.js, it seems I run into the same 3 filenames to describe the main entry point to an app: When using the express-generator package, an app.js file is created as the main entry point for the resulting app. When creating a new package.json file via npm init , one is prompted for the main entry point file. The default is given as index.js . In some programs I have seen, server.js serves as the main entry point as well. Other times, still, it seems as though there are subtle differences in

问题 NetBeans 7.4 beta is currently available for public download, and it introduces a weird warning rule by default: Method length is 16 lines (10 allowed) My question is: Is this an accepted code convention rule, that can be proven somehow, somewhere ? NetBeans support/devs say it's not a bug, but don't give a statement why they only allow 10 lines, and where exactly this rule has its origin. 回答1: You can change the maximum method/function length warning behavior in NetBeans options (it's under

问题 I'm wondering if there is a standard or "normal" means of interpreting time interval data end points with respect to inclusiveness/exclusiveness of the value defining the end point. Note however that I am asking what the standard (or most common) convention is (if there is one), not for a dissertation on your personal preference. If you really want to provide a dissertation, please attach it to a reference to someone's published standard or a standard text on the matter. Open standards (that

Update the question so it can be answered with facts and citations by editing this post. Closed 10 months ago . Is there a standard guideline of what order the CSS properties should be in? This would be to decide if I should use this code p {font-size: 14px; color: purple} or this code instead p {color: purple; font-size: 14px} Edit I am now using The CSS Box Model Convention 回答1:

问题 I came across an interesting comment in php.net about serialize data in order to save it into the DB. It says the following: Please! please! please! DO NOT serialize data and place it into your database. Serialize can be used that way, but that's missing the point of a relational database and the datatypes inherent in your database engine. Doing this makes data in your database non-portable, difficult to read, and can complicate queries. If you want your application to be portable to other
