Hi,
I worked on the implementation of the tracemalloc module and its PEP
454. I consider that this third version of the PEP is ready for a
final review.
What should be done to finish the PEP?

Hi,
some of you may have seen that I'm working on a PEP for a new hash API
and new algorithms for hashing of bytes and str. The PEP has three major
aspects. It introduces DJB's SipHash as secure hash algorithm, chances
the hash API to process blocks of data instead characters and it adds an

Chances are it doesn't. Only a slow enough hash algorithm might have

Hm. I would like to stick to the philosophy that Python's hash should be as
fast as it possibly can be, and should not be mistaken for a cryptographic
