What's the correct way to convert bytes to a hex string in Python 3?
...ook.bin", "rb") as f: # or any binary file like '/bin/ls'
in_bytes = f.read()
print(in_bytes) # b'\n\x16\n\x04'
hex_bytes = binascii.hexlify(in_bytes)
print(hex_bytes) # b'0a160a04' which is twice as long as in_bytes
hex_str = hex_bytes.decode("ascii")
print(hex_str) # 0a160...
Does PostgreSQL support “accent insensitive” collations?
...fortunately, unaccent() is only STABLE, not IMMUTABLE. According to this thread on pgsql-bugs, this is due to three reasons:
It depends on the behavior of a dictionary.
There is no hard-wired connection to this dictionary.
It therefore also depends on the current search_path, which can change easi...

For "read-only" password access, I find the combination of pass with config like this is a bit nicer:

How can I profile C++ code running on Linux?

P.S. This can also be done on multi-thread programs if there is a way to collect call-stack samples of the thread pool at a point in time, as there is in Java.
P.P.S As a rough generality, the more layers of abstraction you have in your software, the more likely...
When are you truly forced to use UUID as part of the design?
... MD5 hash functions respectively, to combine a namespace with a piece of already unique data to generate a UUID. This will, for example, allow you to produce a UUID from a URL. Collisions here are only possible if the underlying hash function also has a collision.
