AtomicInteger lazySet vs. set
...ite. There are a few
other use cases along these lines for non-reference-based
atomics as well, so the method is supported across all of the
AtomicX classes.
For people who like to think of these operations in terms of
machine-level barriers on common multiprocessors, lazySet

How can I generate UUID in C#
...irst three Guid parts.
If you are transmitting the bytes (for example, as base64), you can't just use Guid.ToByteArray() and encode it. You'll need to Array.Reverse the first three parts (Data1-3).
I do it this way:
var rfc4122bytes = Convert.FromBase64String("aguidthatIgotonthewire==");
Array.Re...

Fast way of counting non-zero bits in positive integer
...
I tried adapting Óscar's and Adam's solutions to process the integer in 64-bit and 32-bit chunks, respectively. Both were at least ten times slower than bin(n).count("1") (the 32-bit version took about half again as much time).
On the other hand, gmpy popcount() took about 1/20th of the time of ...
What's the correct way to convert bytes to a hex string in Python 3?
... convenient transformations like quoted-printable (fits into 7bits ascii), base64 (fits into alphanumerics), hex escaping, gzip and bz2 compression. In Python 2, you could do:
b'foo'.encode('hex')
In Python 3, str.encode / bytes.decode are strictly for bytes<->str conversions. Instead, you...
How to deal with SettingWithCopyWarning in Pandas?
...etitem__ operation may not work.
In general, you should use loc for label-based assignment, and iloc for integer/positional based assignment, as the spec guarantees that they always operate on the original. Additionally, for setting a single cell, you should use at and iat.
