Why should I avoid using Properties in C#?
...loading, one of the most effective ways of preventing initialization-order errors.
Change Notifications, which are pretty much the entire basis for the MVVM architecture.
Inheritance, for example defining an abstract Type or Name so derived classes can provide interesting but nevertheless constant m...
LINQ - Full Outer Join
...easible, for two reasons:
Consistency in methods helps save time, avoid errors, and avoid unintended behavior.
If there ever is an out-of-the-box ".FullJoin()" method in the future, I would imagine it will try to keep to the syntax of the currently existing ".Join()" method if it can. If it does...
Optimise PostgreSQL for fast testing
...ds on what else is going on with your machine, and requires some trial and error. The defaults are extremely conservative. You may need to increase the OS's maximum shared memory limit if you increase shared_buffers on PostgreSQL 9.2 and below; 9.3 and above changed how they use shared memory to avo...
JavaScript closures vs. anonymous functions
... JS would be like without closures.
Without closures, this would throw an error
function outerFunc(){
var outerVar = 'an outerFunc var';

In the original EJB spec of 10 years ago, EJBs were a major productivity hassle. They were bloa...
MVVM in WPF - How to alert ViewModel of changes in Model… or should I?
...model itself - when you push data to your Model, it may cause
validation errors. The VM will then have to remap this information
back to the View.
Operations "behind the scenes with no view, like writing to DB,
sending email, etc": This is really part of the "Domain Specific

Calling parent class __init__ with multiple inheritance, what's the right way?
... gives you more consistancy and make eventual refactorings easier and less error-prone. An example of how to do that:
class C(A, B):
def __init__(self):
print("entering c")
for base_class in C.__bases__: # (A, B)
base_class.__init__(self)
print("leaving c"...
What is Ember RunLoop and how does it work?
...ndering DOM elements with updated data -- obviously a very inefficient and error-prone way of emptying all of the RunLoop queues. So Ember intelligently blasts through all the data-binding work it can before rendering the DOM elements in the render queue.
So, finally, to answer your question, yes,...
