Python progression path - From apprentice to guru
... and deep copies (as in Example 3 above), and finally, the interrelationships between the various types and constructs in the language, i.e. lists vs. tuples, dicts vs. sets, list comprehensions vs. generator expressions, iterators vs. generators, etc.; however all those other suggestions are anothe...

Notice that the check phase is immediately after the poll phase. This is because the poll phase and I/O callbacks are the most likely places your calls to setImme...

LINQ to read XML
...
A couple of plain old foreach loops provides a clean solution:
foreach (XElement level1Element in XElement.Load("data.xml").Elements("level1"))
{
result.AppendLine(level1Element.Attribute("name").Value);
foreach (XElement level2Element in level1Ele...
C# Interfaces. Implicit implementation versus Explicit implementation
...inition
IEnumerator enumerableStuff = ((IEnumerable)sl).GetEnumerator();
PS: The little piece of indirection in the explicit definition for IEnumerable works because inside the function the compiler knows that the actual type of the variable is a StringList, and that's how it resolves the function...

...ent multiline construct onto the buffer stack and return to the top-level (PS1) prompt. If the current parser construct is only a single line, this is exactly like push-line. Next time the editor starts up or is popped with get-line, the construct will be popped off the top of the buffer stack a...
Interface vs Base class
...ize "context" because the JVM can often optimize away the slow method lookups. (e.g., if a list of interface inheritors tend to be instances of the same class. This sadly makes benchmarking a tad difficult.) If you're trying to optimize something performance sensitive, and only then, you should c...
Create tap-able “links” in the NSAttributedString of a UILabel?
...ink
Now we should detect touches on this link. The idea is to catch all taps within UILabel and figure out whether the location of the tap was close enough to the link. To catch touches we can add tap gesture recognizer to the label. Make sure to enable userInteraction for the label, it's turned of...

{
ret = fun7(*(a + 4), b);
ret *= 2

If table exists drop table then create it, if it does not exist just create it
...EXISTS `tablename`; before your CREATE TABLE statement.
That statement drops the table if it exists but will not throw an error if it does not.
