How do you keep your backing fields organized? (Styles/Patterns)
c# 3.0 offers us getters and setters with compiler generated backing fields - this is really great, but there are plenty of times that you still need to use a backing field. In a perfect world (opinion), you would be able to do something like class MyClass { ... stuff ... public string MyProperty { private string _myBackingFi...
A particular C programming style problem?
I have heard a lot about the importance of programming style. In my opinion, indention is easy to deal with. But other things frustrated me a lot.

Proxying each method in Ruby
Is this the most efficent way to forward the 'each' call to the Hash's native each method. Should I make @index visible to the outside? I'm a bit unsure as a block is invovled. class TimeSlice def initialize(list) # @index is a hash @index = list.do_some_magic() end def each(&block) @index.each(&block) end end ...

When is it too much "lambda action"?
Hi everybody :) I often find myself using lambdas as some sort of "local functions" to make my life easier with repetetive operations like those: Func<string, string> GetText = (resource) => this.resourceManager.GetString(resource); Func<float, object, string> FormatF1 = (f, o) => String.Format("{0:F1} {1}", f, o); Func<float, object, ...
Why is the usage of "#" comments frequently discouraged in PHP?
As far as I know, there are 3 types of comments recognized by PHP: /* A block comment */ // A single-line comment # Also a single-line comment However, many coding standards, for example, those of PEAR or Kohana, discourage the last type of comments with no explanation. The question is, why is it so? Is this syntax planned for deprec...

VB/VBA Variable Declaration Coding Standard - White Space
What is the significance of declaring variables in VB/VBA like so: Private m_sName As String Private m_lAge As Long As opposed to; Private m_sName As String Private m_lAge As Long I am working on a project which up to now uses the latter, and has done since long before I joined the project. Two new developers have...
Why isn't DRY considered a good thing for type declarations?
It seems like people who would never dare cut and paste code have no problem specifying the type of something over and over and over. Why isn't it emphasized as a good practice that type information should be declared once and only once so as to cause as little ripple effect as possible throughout the source code if the type of somethin...
Is it bad practice to use temporary variables to avoid typing?
I sometimes use temporary variables to shorten the identifiers: private function doSomething() { $db = $this->currentDatabase; $db->callMethod1(); $db->callMethod2(); $db->callMethod3(); $db->... } Although this is a PHP example, I'm asking in general: Is this bad practice? Are there any drawbacks? ...
Proper naming query
Hi i have naming problems with two of my functions i've got a function is_void that returns true if the argument is "empty" (in some sense). How would you call an opposite function? isnt_void? is_set? is_not_void? i have a pair of functions, the first one installs a handler to catch errors in the subsequent code and the second removes...
How to document the Main method?
Okay, so I've got a .NET console application with it's Main method, contained in a Program class. You know, the usual: class Program { static void Main(string[] args) { // Do something spectactular } } Since I've started using StyleCop and FxCop so rigorously, I've become kind of nit-picky about making sure everyth...
Good introduction to generics
Being compelled by the advantages I'm looking for a way to integrate generic programming into my current programming style. I would like to use generics in C# but can't find any good introductory material with some everyday examples of use.

Defining const pointer to a const string
Readed bog of Ulrich Drepper and come across 2 entries that looks like conficting. In the first one (string in global space) Ulrich states that the string should be defines as: const char _pcre_ucp_names[] = "blabla"; while already in second one (string in function) he argues it should be declared as: static const char _pcre_ucp_nam...

Microsoft Internal Coding guidelines: don't use tabs.
Source: http://blogs.msdn.com/brada/articles/361363.aspx Tab characters (\0x09) should not be used in code. All indentation should be done with 4 space characters. Can someone give me an argument as to why this would matter? Shouldn't compilers just ignore this tabs? I always use tabs, just because it's easier and indented code...
