Bolted is a new architecture for a bare metal cloud with the goal of providing security-sensitive customers of a cloud the same level of security and control that they can obtain in their own private data centers.
A Two Sigma engineer explains how how Ibis works with BigQuery to provide an elegant and flexible Python interface for composing SQL queries.
The author walks through how to build a metrics system for a high performance data platform, taking a look at some of the important factors to consider when choosing what open source offerings to use.
Distributed transactions suffer from poor performance due to two major limiting factors. First, distributed transactions suffer from high latency because each of their accesses to remote data incurs a long network delay. Second, this high latency increases the likelihood of contention among distributed transactions, leading to high abort rates and low performance. The authors present Sundial, an in-memory distributed optimistic concurrency control protocol that addresses these two limitations.
This presentation surveys the principles needed for a successful AI programming competition and describes the architecture of the game environment, particularly the support that GCP provided for the support of 12 million game executions written in over 20 programming languages.
Two Sigma’s Co-Founder discusses algorithmic investing, self-driving cars, blockchain, education, and more.
Two Sigma security researcher Trammell Hudson presents his work on the new LinuxBoot firmware—now an official Linux Foundation project.
The NERF and Heads projects bring Linux back to the cloud servers' boot ROMs by replacing nearly all of the vendor firmware with a reproducible built Linux runtime that acts as a fast, flexible, and measured boot loader.
The authors provide a solution for the Efficient Server Audit Problem based on several new techniques, including simultaneous replay and efficient verification of concurrent executions, implemented for PHP web applications.
