Simplifying surds
Recently I am investigating some geometric construction (i.e., compass and ruler constructions) and encounter into the issue of finding sine for some angles. I remember most whole number degree angles could be expressed in surd forms, only it is less pretty than the standard angles of 30°, 45°, 60°. Mostly...

Parsing expression grammar (PEG)
was introduced by Bryan Ford in 20041. Its characteristic is its output is
a single, non-ambiguous parse tree.

Kraska et al (2017) The Case for Learned Index Structure (arXiv)
This paper (PDF) investigates the use of
neural network in deriving index structures (learned indexes), in the
direction to replace B-tree, hash map, or Bloom filters. The paper claims that
the index derived from neural network can outperform B-tree index in both speed
and space.
