SQL Server - Create a copy of a database table and place it in the same database?
...however, are -not- copied.
You can run this query multiple times with a different table name each time.
If you don't need to copy the data, only to create a new empty table with the same column structure, add a WHERE clause with a falsy expression:
SELECT *
INTO ABC_1
FROM ABC
WHERE 1 <>...

If your filenames include whitespace pay careful attention to the "$f" notation. You need the double-quotes to preserve the whitespace.

Transposing a NumPy array
...ly as it's supposed to. The transpose of a 1D array is still a 1D array! (If you're used to matlab, it fundamentally doesn't have a concept of a 1D array. Matlab's "1D" arrays are 2D.)
If you want to turn your 1D vector into a 2D array and then transpose it, just slice it with np.newaxis (or None,...
Why does SSL handshake give 'Could not generate DH keypair' exception?
...existence of servers which request a larger size! :( I tried BouncyCastle; if you set it up as preferred provider it crashes with a different exception (sigh), and I can't see an obvious way to use that just for DH. However, I found an alternative solution, which I'll add as a new answer. (It's not ...
Are lists thread-safe?
...r example:
L[0] += 1
is not guaranteed to actually increase L[0] by one if another thread does the same thing, because += is not an atomic operation. (Very, very few operations in Python are actually atomic, because most of them can cause arbitrary Python code to be called.) You should use Queues...

...addirSync(testFolder).forEach(file => {
console.log(file);
});
The difference between the two methods, is that the first one is asynchronous, so you have to provide a callback function that will be executed when the read process ends.
The second is synchronous, it will return the file name a...
How do I find the location of the executable in C? [duplicate]
...me/where/else/foo # create a hard link to foo
$ /some/where/else/foo
Now, the approach above (including, I suspect, /proc/$pid/exe) will give /some/where/else/foo as the real path to the program. And, in fact, it is a real path to the program, just not the one you wanted. Note that this prob...
How to take the first N items from a generator or list in Python? [duplicate]
...tart, stop, step)
Remember, slicing a generator will exhaust it partially. If you want to keep the entire generator intact, perhaps turn it into a tuple or list first, like: result = tuple(generator)
