The subject? Hash tables. These are very useful tools to have in your arsenal. It just takes a while to both (a) understand them and their use fully and (b) wrap your head around the extremely ...

In the world of decentralization, distributed hash tables (DHTs) recently have had a revolutionary effect. The chaotic, ad hoc topologies of the first-generation peer-to-peer architectures have been ...

Researchers have shown how a flaw that is common to most popular Web programming languages can be used to launch denial-of-service attacks by exploiting hash tables. Announced publicly on ...

A lookup table that is designed to efficiently store non-contiguous keys (account numbers, part numbers, etc.) that may have wide gaps in their alphabetic or numeric sequences. THIS DEFINITION IS ...

Seventy years after the invention of a data structure called a hash table, theoreticians have found the most efficient possible configuration for it. About 70 years ago, an engineer at IBM named Hans ...

The result has been an almost endless number of hashing methods and tables. Facebook has faced this problem as well. Within its offices, Facebook developers have created numerous hash table ...

A young computer scientist and two colleagues show that searches within data structures called hash tables can be much faster than previously deemed possible. Sometime in the fall of 2021, Andrew ...

which transforms the implementation into a probing hash table (think dense_hash_set). The linked list is gone and replaced with an implicit list in the pointer array. The tradeoff is that you can ...

It isn't often that a decades-old assumption underpinning modern technology is overturned, but a recent paper based on the work of an undergraduate and his two co-authors has done just that.
