Finding Great (and Profitable) Ideas in the Computer Science Literature

I spend quite a bit of time trawling through recent computer science papers, looking for anything algorithmic that might improve my team’s product and Help People Get Jobs. It’s been a mixed bag so far, often turning up a bunch of pretty math that won’t scale at Indeed. But looking through the computer science literature can […]

Vectorized VByte Decoding: High Performance Vector Instructions

Data-driven organizations like Indeed need great tools. We built Imhotep, our interactive data analytics platform (released last year), to manage the parallel execution of queries. To balance memory efficiency and performance in Imhotep, we developed a technique called vectorized variable-byte (VByte) decoding. VByte with differential decoding Many applications use VByte and differential encoding to compress […]
