Many standard C and POSIX functions return -1 for error, and 0 on success, for example truncate, fflush, msync, etc. int ret = truncate("/some/file", 42); Is it better practice to check for success with ret != -1 or ret == 0, and why? My Thoughts It's my experience most people check for the error case (ret != -1), as there is typica...
I'm using fluent-nhibernate conventions to map my entityies: public class HasManyConvention : IHasManyConvention { public void Apply(FluentNHibernate.Conventions.Instances.IOneToManyCollectionInstance instance) { instance.Key.Column(instance.EntityType.Name + "ID"); instance.Cascade.AllDelete...
Hi! I'm implementing IObserver. Are there any conventions about throwing exceptions from IObserver? Can OnNext or any other method of my implementation throw exceptions? What should happen if exception is thrown in OnNext or OnCompleted - should I catch all exceptions and call this.OnError(ex)? What will happen if OnError throws? ...

I like to give my variables, methods and objects descriptive names. Obviously not going overboard, but let me give you a couple of examples. public class Account { public decimal Balance { get; set; } } Account account = new Account(); account.Balance = 1000; Some people would opt to go for the following, which really does not ma...
What should be documented by javadoc comments (classes, methods, constructors and fields? Or only classes methods and constructors?)? Is there any convention about that ? Please provide links to relevant resources in your answer whenever possible. Thank you EDIT: The question is not about how is it usualy done or what is logical to com...
Right now I've got a project that has the following layout: foo/ __init__.py __main__.py foo.py In this case, foo.py is actually the main api file, so developers are meant to do "from foo import foo", but I also wanted to make it so that end users could just run ~$ foo and get an interface. which, when I do a distutils install,...
I do not know what to call my "setters" on immutable objects? For a mutable object Person, setters work like this: class Person(private var _name: String) { def name = "Mr " + _name def name_=(newName: String) { _name = newName } } val p = new Person("Olle") println("Hi "+ p.name) p.name = "Pelle" println("Hi "+ p.name) Th...
Possible Duplicate: Java - when to use 'this' keyword Is it generally good convention to references class attributes with 'this.' even if it would reference the attribute by default anyway? Or should I only use it when absolutely necessary? It would make things clearer to the programmer, and to avoid any confusing errors if t...
Where can I learn more about simple programming conventions and design patterns? When I say simple I mean which is the preferred way of writing the following equivalent functions: function() { if (condition) { # condition wraps the entire function } } or function() { if (!condition) { return; } # rest of the funct...
Just had a 'Fundamentals of Programming' lecture at uni and was told that the convention for using/declaring functions is to have the main() function at the top of the program, with functions/procedures below it and to use forward declarations to prevent compiler errors. However, I've always done it the other way - functions at top main...
Is there any REST convention for handleling resources with slashes?
