Debugging Package Manager Console Update-Database Seed Method
... the Seed method.
You may take this one step further and construct a unit test (or, more precisely, an integration test) that creates an empty test database, applies all EF migrations, runs the Seed method, and drops the test database again:
var configuration = new DbMigrationsConfiguration<TCo...
How to detect if a script is being sourced
...
A line similar to this or an assignment like pathname="$_" (with a later test and action) must be on the first line of the script or on the line after the shebang (which, if used, should be for ksh in order for it to work under the most circumstances).

How dangerous is it to compare floating point values?
... interval!) can be assigned that's all graphics needs.
So if you want to test if your point is outside a [0..width[ range this is just fine. Just make sure you define inclusion consistently. For example always define inside is (x>=0 && x < width). The same goes for intersection or hi...
Create a string of variable length, filled with a repeated character
...ls.
On Firefox, Chrome, Node.js MacOS, Node.js Ubuntu, and Safari, the fastest implementation I tested was:
function repeatChar(count, ch) {
if (count == 0) {
return "";
}
var count2 = count / 2;
var result = ch;
// double the input until it is long enough.

java.lang.OutOfMemoryError: Java heap space
...better for it.
To determine where the memory leak may be you can use unit tests for that, by testing what was the memory before the test, and after, and if there is too big a change then you may want to examine it, but, you need to do the check while your test is still running.

...k as intended using this exact format. Upon reading your response I even retested both for the match and lack thereof. $# will not contain a value if not specified, if there is no positional argument to match what ever # is in your scenario. It makes no sense why bash would assume a value in a posi...
Python ElementTree module: How to ignore the namespace of XML files to locate matching element when
