Objective-C formatting string for boolean?
...
One way to do it is to convert to strings (since there are only two possibilities, it isn't hard):
NSLog(@" %s", BOOL_VAL ? "true" : "false");
I don't think there is a format specifier for boolean values.

How to add a new row to an empty numpy array
...it would be much faster to append to a list as in your first example, then convert to a numpy array at the end, since you're really not using numpy as intended during the loop:
In [210]: %%timeit
.....: l = []
.....: for i in xrange(1000):
.....: l.append([3*i+1,3*i+2,3*i+3])
.....:...
This Handler class should be static or leaks might occur: IncomingHandler
...the whole point. Unless he has some ultra cool compiler that automatically converts inner classes to static classes when they don't use class variables.

What's invokedynamic and how do I use it?
...ions on the types of values supplied to its operations (e.g. Java)
Weak - converts (casts) arguments of an operation if those arguments have incompatible types (e.g. Visual Basic)
Knowing that Java is a Statically and Weakly typed, how do you implement Dynamically and Strongly typed languages on t...
Why doesn't the example compile, aka how does (co-, contra-, and in-) variance work?
...?
slot.get will then throw an error at runtime as it was unsuccessful in converting an Animal to Dog (duh!).
In general mutability doesn't go well with co-variance and contra-variance. That is the reason why all Java collections are invariant.

How to output something in PowerShell

Objects also don't get blindly converted to string, but pass through a formatter which decides on what to do with them. That's why you see Get-ChildItem's output coming in a table form, for example, and results with many properties (e.g. WMI) default to Fo...

Why not use java.util.logging?
...o I would think that a massive library written in 2002 with log4j could be converted to JUL in a matter of minutes with an automated tool. (I don't know if one exist, though). So why doesn't it happen?

PowerShell script to return versions of .NET Framework on a machine?
... slightly again, so there's now a nice MSDN article here explaining how to convert the Release value to a .Net version number, it's a total train wreck :-(
This looks right to me (note that it outputs separate version numbers for WCF & WPF on 3.0. I don't know what that's about). It also output...
What are bitwise shift (bit-shift) operators and how do they work?
...d together makes 320:
(row * 320) = (row * 256) + (row * 64)
Now we can convert that into left shifts:
(row * 320) = (row << 8) + (row << 6)
For a final result of:
memoryOffset = ((row << 8) + (row << 6)) + column
Now we get the same offset as before, except instead ...
