  • Details of RFC 2326 10.12

    - by VSC
    I am using RFC 2326 10.12 and I want to make sure I am correct. The examples confuse me. From what I understand, the header described consists of four bytes. [$][channel#][MSByte of length][LSByte of length]{data...} Is this the common convention?

  • Using NULL in MySQL

    - by JPro
    The data in my dabatase comes from an external source and where ever there is no data passed, I keep NULL in those places. Can anyone tell me if there are any implications in using NULL to represent empty value? Should I follow some other convention like 'data_not_available'? or something like that? Can anyone suggest?

  • Exposing members or make them private in Python?

    - by deamon
    Is there a general convention about exposing members in Python classes? I know that this is a case of "it depends", but maybe there is a rule of thumb. Private member: class Node: def __init__(self): self.__childs = [] def add_childs(self, *args): self.__childs += args node = Node() node.add_childs("one", "two") Public member: class Node2: def __init__(self): self.childs = [] node2 = Node2() node2.childs += "one", "two"

  • Python: When passing variables between methods, is it necessary to assign it a new name?

    - by Anthony
    I'm thinking that the answer is probably 'no' if the program is small and there are a lot of methods, but what about in a larger program? If I am going to be using one variable in multiple methods throughout the program, is it smarter to: Come up with a different phrasing for each method (to eliminate naming conflicts). Use the same name for each method (to eliminate confusion) Just use a global variable (to eliminate both) This is more of a stylistic question than anything else. What naming convention do YOU use when passing variables?

  • Table Naming Dilemma: Singular vs. Plural Names

    - by ProfK
    Convention has it that table names should be the singular of the entity that they store attributes of. I dislike any T-SQL that requires square brackets around names, but I have renamed a Users table to the singular, forever sentencing those using the table to sometimes have to use brackets. My gut feel is that it is more correct to stay with the singular, but my gut feel is also that brackets indicate undesirables like column names with spaces in them etc. Should I stay, or should I go?

  • Programatically importing a file and creating an instance of a class in Python

    - by benofsky
    I have a (python) list of strings which refer to python source files and subsequently classes within those files which I want to import and then create an instance of the classes within the files (everything follows a strict naming convention, making this theoretically possible), in Ruby I would do something like: require "lib/sources/#{source}.rb" s = source.constantize.new How would I do something similar in Python? Thanks, Ben

  • In which situation is the c++/c# namespace approach better than the Java approach?

    - by mike g
    The reason I ask this is that c# could easily have copied the java convention, or a variation of it, but opted for the more flexible approach of explicitly declaring namespaces inside files. As a Java programmer often there are things that I wish I could do differently, but namespaces is not one of them. The flexbility has a certain overhead (extra braces, extra decisions for developers, making it harder to view a projects contributions to the namespace, at least without a specialist IDE). So what practical examples are there when this flexiblity is advantageous?

  • Is there any difference between "foo is None" and "foo == None"?

    - by Joe Shaw
    Is there any difference between: if foo is None: pass and if foo == None: pass The convention that I've seen in most Python code (and the code I myself write) is the former, but I recently came across code which uses the latter. None is an instance (and the only instance, IIRC) of NoneType, so it shouldn't matter, right? Are there any circumstances in which it might?

  • Python `if x is not None` or `if not x is None`?

    - by orokusaki
    I've always thought of the if not x is None version to be more clear, but Google's style guide implies (based on this excerpt) that they use if x is not None. Is there any minor performance difference (I'm assuming not), and is there any case where one really doesn't fit (making the other a clear winner for my convention)?* *I'm referring to any singleton, rather than just None. ...to compare singletons like None. Use is or is not.

  • C# empty statement

    - by dotnetdev
    In C#, I can write something like: using (new MyDisposableClass().MethodA()); The semicolon causes a compiler warning to be shown which states possible mistaken empty statement. I haven't run the above code but won't the method still be called? What uses is there of this type of coding convention? I saw another thread on here about this but I ask in case there areny differences now/therefore different replies. Thanks

  • Parent reference in automapped component

    - by asgerhallas
    In Fluent NHibernate, given an automapped component, is there a convention for setting up a parent reference back to the "holder" of the component? By having for example a property named Parent or something like that? I can't seem to find any information about how to do it or issues about it.

  • relaxng schema - use attributes for members and elements for structures?

    - by rpkrpk
    For a data-binding application, I am trying to draw parallels among RelaxNG, C++ and C. RelaxNG.Elements === C++.Class === C.Struct RelaxNG.Attributes === C++.class-members === C.structure-members Only that the Elements in RelaxNG can also have a data-type (i.e. it seems Attribute is a special case of the Element). Do I have the above equivalence correct? If I use the above convention in my implementation, will I be breaking some data-binding libraries?
