Well, I think I already have part of the answer.
There are two aspects to the problem: the compression, and the integers.
About the compression, I would need to enable this module:
About the gremlins ("32 bits unsigned big endian integers, one integer"), we
may have more of a problem:
""The size of an integer is platform-dependent, although a maximum value of
about two billion is the usual value (that's 32 bits signed). PHP does not
support unsigned integers.""
Is the solution as easy as handling the signs properly?
If I have (trying to guess):
a = -3,
b = -1,
c = 0,
d = 1,
e = 3
Then the proper order is:
c = 0,
d = 1,
e = 3,
b = y + 1,
a = y + 3
Because we and the world need to change.
Intimate Relationships, peace and harmony in the couple.
