[Links of the Day] 24/07/2018 : Physics of baking a good pizza, Stagnation of incomes despite Economic growth, Asciinema

  • The Physics of baking good Pizza : when physicist tries to bake good pizza they write a paper about it. 
  • Stagnating median incomes despite economic growth : a look at the reason behind income stagnation despite an almost continuous economic growth for the past 20+ years. One of the worrying aspects is that it points out to an increase in wealth inequality which can lead to social unrest. Another interesting aspect is that the USA is a clear outlier as the wage growth was significantly lower than in OECD countries. This could provide a hint as to why this country is currently in such turmoil as the inequality gap has widened exponentially over the past couple of years.

[Links of the Day] 24/04/2017 : Data Center Perf Index, Physical Limits of Computing And DNS as Code


  • Data Center Performance Index : Performance index aiming at providing a reliable idea of the performance and efficiency of the datacenter. It primarily focuses on Availability, Efficiency and Environmental impact. This effort is lead by Dean Nelson, Uber Had of computing. 
  • Physical Limits of Computing : A look at the limitation of compute from a physicist point of view. It seems that some limitations are fundamental and require a new and different approach in order to create compute device that goes around these limitations. 
  • DnsControl : system built to manage DNS systems. To some extent, it looks like a terraform for DNS where you can plug multiple DNS backend providers. This allows you to deploy and distribute your DNS infra in an agnostic way across multiple cloud provider. [github]

[Links of the day] 16/06/2016 : Bayesan Betancourt's lecture, Physic breakthrough & Distributed systems, Linux Kernel Radix tree

  • Betancourt Binge : Michael Betancourt’s video lectures in Tokyo, all about Bayesian model. 
  • Standing on Distributed Shoulders of Giants : as usual excellent ACM queue article drawing parallel between physics breakthrough and the world of distributed systems. 
  • Multi-order radix tree : The Linux kernel radix tree is a data-structure at the centerpiece of the memory management system. With the advent of new memory model ( persistent one). This data-structure needs to evolve. However, like with everything touching memory, it will take some time and many many re-submission to the mailing list. This article present a possible evolution path for this venerable data-structure.
