The author is developing a proof of concept for a Redis RESP3-compatible key/value database based on FoundationDB, which has presented interesting challenges in distributed systems. Previously, they built a Graph DB using Roaring Bitmaps to represent relationships, allowing for efficient boolean operations on large sets of user IDs. However, with the need to accommodate millions of records and possibly more than 15 billion unique URIs in the AT Proto Ecosystem, the keyspace exceeded the limitations of uint32 values. They decided to

The increasing complexity of large neural network models, particularly in language and image processing, presents deployment challenges due to high memory demands and computational inefficiency. A novel strategy introduced in this work involves the development of models that utilize single-bit parameters, allowing all parameters in the layers—like kernel weights and biases—to be either zero or one. These models are built using "binary normalized layers," which can be adapted from traditional layer types, such as fully connected and convolutional layers. To demonstrate their effectiveness,
