Can I pass an array as arguments to a method with variable arguments in Java?
...rraycopy(arr, 0, arr, 1, N);
arr[0] = firstElement;
return arr;
}
Now you can do the following:
String[] myArgs = { "A", "B", "C" };
System.out.println(ezFormat(append(myArgs, "Z")));
// prints "[ A ][ B ][ C ][ Z ]"
System.out.println(ezFormat(prepend(myArgs, "Z")));

Memory footprint of Haskell data types
...ords, and a Due takes 3.
The Int type is defined as
data Int = I# Int#
now, Int# takes one word, so Int takes 2 in total. Most unboxed types take one word, the exceptions being Int64#, Word64#, and Double# (on a 32-bit machine) which take 2. GHC actually has a cache of small values of type Int...

Now consider a theta eqijoin, where the column names for the join must be explicitly specified (plus range variables S and SP are required):
SELECT * FROM S JOIN SP ON S.SNO = SP.SNO;
The resultset will have seven columns,...
Why is a 3-way merge advantageous over a 2-way merge?

Do you need to dispose of objects and set them to null?
... that (just) compiles but to write code that runs. Sometimes it helps to know what the runtime is doing under the covers (e.g. troubleshooting). One could argue that it's the type of knowledge that helps to separate good programmers from great programmers.

Why is GHC so large/big?

Now that I think GHC uses dynamic linking, perhaps Dr. @Simon Marlow's ideas for compression of the four flavors is more practical? Cites: 1.#3658 (Dynamically link GHCi (and use system linker) on platforms that support it) ...
What's the difference between EscapeUriString and EscapeDataString?
...at
That's a valid URI (try it), and EscapeUriString will not modify it.
Now consider querying Google for "happy c++":
https://www.google.com/?q=happy+c++
That's a valid URI (try it), but it produces a search for "happy c", because the two pluses are interpreted as spaces. To fix it, we can ...
