Researchers at the National Unviersity of Singapore have developed a system called SpiKey that can predict 10 possible options of a key design just by recording the sound of a key in a lock. Of the 586,584 possible key combinations for a 6-pin lock, SpiKey can be used on approx. 56% of them to generate candidate key options that will open the lock.

Onat Yigit Mercan posted a great explainer on Bloom filters, a data structure used as a sort of fuzzy hash map for membership of collections. The filters can be used to query if items are in a large database without using large amounts of memory. For example, a database of 1 million entries can use a bloom filter of just 1.14MB.
