What is two way binding?
...t two-way binding: while not a core feature of the framework, it can be performed quite simply using Backbone's Events though. It costs a few explicit lines of code for the simple cases; and can become quite hazardous for more complex bindings. Here is a simple case (untested code, written on the fl...
Best practices for exception management in Java or C# [closed]
... do something based on it. Or if I want to provide additional contextual information in an exception.
I use a general try catch at the application entry point, or the highest level possible. If an exception gets here I just log it and let it fail. Ideally exceptions should never get here.

Pass arguments to Constructor in VBA
...claredId have a "global instance" that you get for free - exactly like UserForm modules (export a user form, you'll see its predeclaredId attribute is set to true).
A lot of people just happily use the predeclared instance to store state. That's wrong - it's like storing instance state in a static ...

Why use apparently meaningless do-while and if-else statements in macros?
...
Note: the if(1) {...} else void(0) form is safer than the do {...} while(0) for macros whose parameters are code that is included in the macro expansion, because it doesn't alter the behavior of the break or continue keywords. For example: for (int i = 0; i &l...
Strip HTML from strings in Python
...g to find a way to only show the contents of each HTML element and not the formatting itself. If it finds '<a href="whatever.com">some text</a>' , it will only print 'some text', '<b>hello</b>' prints 'hello', etc. How would one go about doing this?

Views vs Components in Ember.js
...ensure our implementation of components matches the roadmap of the web platform.
Also important to note is that a Ember.Component is actually a Ember.View (a subclass) but that is completely isolated. Property access in its templates go to the view object and actions are targeted also at the view o...
Declaring variables inside loops, good practice or bad practice?
...enced elsewhere.
Last but not least, some dedicated optimization can be performed more efficiently by the compiler (most importantly register allocation), since it knows that the variable cannot be used outside of the loop. For example, no need to store the result for later re-use.
