Is using Random and OrderBy a good shuffle algorithm?
...ick of hearing from me on this, but I ran into a slight problem in my unit tests that you might want to be aware of. There's a quirk with ElementAt that makes it invoke the extension each time, giving unreliable results. In my tests I'm materializing the result before checking to avoid this.

Display an array in a readable/hierarchical format
...$v) echo $v, PHP_EOL;
UPDATE: A more sophisticated solution would be:
$test = [
'key1' => 'val1',
'key2' => 'val2',
'key3' => [
'subkey1' => 'subval1',
'subkey2' => 'subval2',
'subkey3' => [

SQL to determine minimum sequential days of access?
...
Truncate the CreateionDate down to days in all these tests (on the right side only or you kill SARG) using DATEADD(dd, DATEDIFF(dd, 0, CreationDate), 0) This works by subtracting the supplied date from zero--which Microsoft SQL Server interprets as 1900-01-01 00:00:00 and gives...
What's the difference between the Dependency Injection and Service Locator patterns?
...One important result of this is that the DI example is much easier to unit test -- because you can pass it mock implementations of its dependent objects. You could combine the two -- and inject the service locator (or a factory), if you wanted.
