It’s official! Fast Flexible Paxos: Relaxing Quorum Intersection for Fast Paxos, my latest collaboration with Aleksey Charapko and Richard Mortier will appear in next year’s edition of the International Conference on Distributed Computing and Networking (ICDCN). If you don’t want to wait, then the paper is available right now on Arxiv and in the next […]
Practical Byzantine Fault Tolerance (PBFT) is the foundational paper in Byzantine consensus algorithm. Typically, distributed consensus algorithms assume nodes may fail (and possible recovery), but BFT extends this to tolerate nodes acting arbitrarily. Assumptions BPFT makes strong assumption about these arbitrary failures. Notability that at most f failures will occur in a system of 3f+1 […]
The videos of my talk and interview at this year’s J on the beach are now live and embedded below.
Just like humans organising to meet for coffee, computers need ways of organising themselves. Heidi Howard, of the System Research Group at University of Cambridge explains the basics.

The responses where fairly disappointing but it helps to keep the debate alive.
In this post we will be looking at the results for the Azure latency Pilot study described last week. Yesterday, we started by looking at the aggregated results and found that the measured RTT was larger then expected. Today, we will look at how the results vary depending on which VMs the measurements where taken […]
This is post we will be looking at the results for the Azure latency Pilot study described last week. We will starting by looking at the aggregate results, disregarding the time a measurement was taken and which machines the measurement was taken between. The 22332 data points have been processed in Python3, in particular using […]
I’ll just leave this here, my all time favourite youtube video
Thanks to Justine, at the excellently named Lavender Martini Border Gateway Protocol for sharing a link to this blog post on Prospective Students and Lab Culture. Useful food for thought, not just for Part 2 students.
