[Links of the Day] 25/01/2018 : VPS comparison, Scale free network are rare and Data mining OCR PDFs

  • VPS Comparison : this provides a very good overview of the different VPS provider out there. Obviously not complete, but hey, I would love to see a benchmark community driven website maintaining comparison for the different providers. Not just VPS, cloud / paas / lambda etc..
  • Scale-free networks are rare : the ideal scale-free network does not really happen that often in the wild ( of the internet). Maybe its time to go beyond this concept and explore other more realistic avenues for real-world networks ( I'm looking at your distributed network of microservice) 
  • Data Mining OCR PDFs : extracting info from PDF is a nightmare, it's even worse when you have to do OCR and I always considered that tabulation was a no go territory. But looks like somebody actually spent the effort to make it work and it's impressive.

[Links of the Day] 27/06/2017 : Blockchain trust & authentication for IoT, K8s patterns, Ripple cryptocurrency Network analysis

  • Kubernetes Production Patterns and anti-patterns :  a lot of common sense, actually a lot of the patterns and anti-patterns can be applied to the other environments. But still a good refresher. 
  • Blockchain based trust & authentication for decentralized sensor networks : using blockchain to solve the trust issue in a swarm of IoT on a network. The critical bit missing is the power requirement for running all the crypto operations.
  • Large-Scale Analysis of the Ripple Cryptocurrency Network : an overview of the paper analysing the Ripple p2p blockchain based money transaction network. Turns out it suffer the same issue that "old school" p2p network. Take out the highly connected nodes and you can bring down / split the network. Nothing new, but still a good read and reminder that small network tends to be resilient to attack. But, if their resiliency diminishes with the increased reliance on a small number of highly connected nodes.

[Links of the Day] 12/04/2017: Linux Perf tools, libp2p and Contagion of Information in Social Media

  • Perf Tools : miscellaneous collection of in-development and unsupported performance analysis tools for Linux ftrace and perf_events. 
  • Contagion of Information in Social Media :  The authors look at how information spread on social media ( twitter ). The authors model contagion behaviour in the hope to create effective defences against "fake news" and other propaganda. However, to some extend the research can also be used to optimise the spread of such malicious information. 
  • libp2p :  really cool network stack ( used by IPFS) that tackle a lot of the nitty gritty detail of p2p applications. It should allow devs to focus on the actual value of their p2p apps rather than the technical underlying problems of p2p itself. [github]
