问题 I've learned that a process has the following structure in memory: (Image from Operating System Concepts, page 82) However, it is not clear to me what decides that a process looks like this. I guess processes could (and do?) look different if you have a look at non-standard OS / architectures. Is this structure decided by the OS? By the compiler of the program? By the computer architecture? A combination of those? 回答1: Related and possible duplicate: Why do stacks typically grow downwards?.

问题 Whenever you declare the main method in a class, you always have to do a String array called "args". What's the point? Unless I live under a rock, command line agruments in Java are barely used anymore. And when I try and run this... //this program won't compile public class SomeClass { public static void main(){ System.out.println("This text will never be displayed :("); } } The output shows this in red text: Error: Main method not found in class SomeClass , please define the main method as:

问题 It is a Ruby convention to use #=> for describing expected returns. I realized that I use # => (with some space or tabs) myself. This is just a convention, and there is no formal specification, so I would like to ask what the convention is among Ruby programmers. Is #=> the only correct way or is preferred, # => is preferred, or Either is almost equally used? And, would there be any reasons to exclude or prefer one form? 回答1: I wouldn't say it's a convention. At least, I haven't read anywhere

Update the question so it can be answered with facts and citations by editing this post. Closed 6 years ago . I was wondering if there are best practices for avoiding monolithic js files in AngularJS. I would like to avoid having very large controllers.js/filters.js/services.js files. Instead, for the sake of manageability, I would like to have each controller/filter/service in its

问题 Is there a convention for naming tables when using Doctrine ORM? I like to name tables with the plural but if there's a convention I want to stick to it. So the table 'users' would be related to tables using the fk as the singular ('user_id'). Is there a best practice for this (using singular or plural table names) and if the latter, how does this apply to tables where the plural isn't a simple case of adding an 's'. For example I currently have a table called 'categorys' instead of

问题 No matter which C-compatible library I use, when I look at the header defined constants, they are always defined as hexadecimal values. Here, for instance, in GL/gl.h: #define GL_POINTS 0x0000 #define GL_LINES 0x0001 #define GL_LINE_LOOP 0x0002 #define GL_LINE_STRIP 0x0003 #define GL_TRIANGLES 0x0004 #define GL_TRIANGLE_STRIP 0x0005 #define GL_TRIANGLE_FAN 0x0006 #define GL_QUADS 0x0007 #define GL_QUAD_STRIP 0x0008 #define GL_POLYGON 0x0009 Is there any particular reason for this convention,

问题 Could anyone explain why single element tuple is interpreted as that element in Python? And Why don't they just print the tuple (1,) as (1) ? See the examples below: >>> (1) 1 >>> ((((1)))) 1 >>> print(1,) 1 >>> print((1,)) (1,) 回答1: A single element tuple is never treated as the contained element. Parentheses are mostly useful for grouping, not for creating tuples; a comma does that. Why don't they just print (1,) as (1)? Probably because printing a builtin container type gives a
