Is there hard evidence of the ROI of unit testing?
...mmers and, more importantly, the bean-counters in management, that all the extra time spent learning the testing framework, writing tests, keeping them updated, etc.. will pay for itself, and then some.

What is the difference between UTF-8 and Unicode?
...ively space-efficient, but the downside that operations such as finding substrings, comparisons, etc. all have to decode the characters to unicode code points before such operations can be performed (there are some shortcuts, though).
Both the UCS standards and the UTF standards encode the code poi...
Setting an object to null vs Dispose()
...ode) to know when you're not going to use a reference again. For example:
StringBuilder sb = new StringBuilder();
sb.Append("Foo");
string x = sb.ToString();
// The string and StringBuilder are already eligible
// for garbage collection here!
int y = 10;
DoSomething(y);
// These aren't helping at...
Do DOM tree elements with ids become global variables?
...article about why global variables are bad. Simply put, having a bunch of extra global variables leads to more bugs. Let's say you accidentally type the name of a var and happen to type an id of a DOM node, SURPRISE!
Additionally, despite being standardized there are still quite a few discrepanci...
Generate random number between two numbers in JavaScript
... a | 0 is also the fastest and most optimized way to convert a string to an integer. It only works with strings containing integers ("444" and "-444"), i.e. no floats/fractions. It yields a 0 for everything that fails. It is one of the main optimizations behind asm.js.

Which encoding opens CSV files correctly with Excel on both Mac and Windows?
...king good with special characters and separated fields. I start my output string with "\ufeff" as a byte order mark (BOM), then using "\t" tabs in place of commas for field separation, and encoding the file with "utf-16LE". Works like a charm, thanks to this page!
