Indexing the Pickup and Drop-Off Locations of NYC Taxi Trips in PostgreSQL - Lessons from the Road

In this paper, we present our experience in indexing the dropoff and pick-up locations of taxi trips in New York City. The paper presents a comprehensive experimental analysis of classic and state-ofthe-art spatial database indexing schemes. The paper evaluates a popular spatial tree indexing scheme (i.e., GIST-Spatial), a Block Range Index (BRIN-Spatial) provided by PostgreSQL as well as a new...

Secure Remote Access to an Internal Web Server Secure Remote Access to an Internal Web Server

We address the problem of secure remote access to a site's internal web server from outside the rewall. The idea is to give authorized users access to sensitive information, while protecting the information from others. We implemented our solution using a one-time password scheme for client authentication and SSL for conndentiality. Our main design considerations were security, performance, eas...

Absolute distance perception to locations off the ground plane.

Using vision, humans can accurately judge distances to locations on the ground surface up to distances of at least 20 m. Most theories of depth perception assume that this ability is associated with the fact that we live in a terrestrial world in which locations of interest often appear on the ground and for which feedback about distance is often available from nonvisual sources such as walking...

Secure SQL Server - Enabling Secure Access to Remote Relational Data
