The team’s system sorted almost three times the amount of data (1,401 gigabytes vs. 500 gigabytes) with about one-sixth the hardware resources (1,033 disks across 250 machines vs. 5,624 disks across 1,406 machines) used by the previous record holder, a team from Yahoo! that set the mark in 2009.

Google developer Tom Herbert submitted two major improvements to the network subsystem of Linux 2.6.35: Receive Packet Steering (RPS) and Receive Flow Steering (RFS). RPS distributes the processing steps for handling received network packets across the available processor cores so that these can work in parallel from the protocol layer onwards. Which cores receive how much work can be determined using a bit mask that is controllable via Sysfs. RFS, together with other functions, is said to offer a software emulation of the multi-queue functionality found in network cards (NICs). However, in his commit comment, which also includes tips for practical use, Herbert said that this approach has its disadvantages. The developer also lists test results which confirm that, in some cases, the technology considerably increases network throughput.

The goal of motion pictures is not to recreate reality, it's not even to show reality. I want to create a little psychic link between you and my pictures. I want to suck you into the world of the story, suspend your disbelief and make you forget about yourself and your life and just be in the moment of the film. By not showing enough visual information, we force the brain into filling in the gaps... it draws you in even more. It's part of how you let go to the point where you can laugh or cry or feel tense or afraid or elated.

A Programming Language for Genetic Engineering of Living Cells

We introduce such a programming language, which allows logical interactions between potentially undetermined proteins and genes to be expressed in a modular manner. Programs can be translated by a compiler into sequences of biological parts, a process which relies on logic programming and prototype databases containing known biological parts and protein interactions. Programs can also be translated to reactions, allowing simulations to be carried out. The language is a first step towards the automatic translation of high-level behavioural designs to low-level DNA code.
