Given the latest miserable failure of the whole PHP ecosystem, the question remains whether it is not better to just abandon anything even remotely relying on this rather strange programming language.

You use ChaCha20 as your symmetric stream cipher of choice for encrypted containers and then you try to map those containers on a simple TLS connection. If you really tried, you've already noticed the issue. ChaCha20 is NOT a single cipher anymore.

Today I've got a purely personal post to publish which has been probably due for quite some time. I am back in academia and I finally put up my researcher homepage a suggested by my faculty.

Having dealt with equality allowed us to add the missing link between a year of stream fusion development and a new rolling Qi release. Let us have a quick look at what is finally out in the fields and which operations are now optimized!

Implementing optimized versions of certain operations is typically both useful and fun. However, once the implementations have to replicate a particular equality predicate, verifying - or at least testing - becomes a nightmarish experience. Let us dive knee-deep in the behavioral predicates of different equality definitions.
