Toast was my first published short story collection. It's now effectively out of print — there was going to be a limited, signed, "final" edition, but I haven't seen hide nor hair of it for a year or two now — so I'm releasing it under a Creative Commons license.
In the previous posts, we've explored the SQLite file format and built a simple SQL parser. It's time to put these pieces together and implement a query…
StringZilla v4 brings CUDA acceleration for string processing: 109x faster than Nvidia's CuDF on edit distances, plus 52-bit MinHash fingerprinting and AES-based hashing.
