[Links of the Day] 29/05/2018 : Tracers performance, Testing Terraform , Virtual-kubelet

• Benchmarking kernel and userspace tracers : a good recap of what tracing toolkit is out there and the performance tradeoff that comes with them
• terratest : this is the thing I was looking for, a way to test and validate my terraform script. This will really help the adoption of Terraform I think as it will significantly increase the confidence in Terraform code before deployment.
• Virtual-Kubelet : that s a really cool concept, and introduce a great dose of flexibility in your Kubernetes cluster deployment. There is already some really exciting solution leveraging it such as the AWS fargate integration. With this, you could implement easily bursting and batching solution or real hybrid k8s solution with virtual kubelet hosted in Azure, Aws and on your private cloud.  

[Links of the Day] 28/11/2016 : Earth Computing network fabric, CS video courses, Go app tracing

• Earth Computing Network Fabric : event based protocol for datacenter that target specifically datacenter as it eliminate the need for heartbeats and timeouts. The protocol relies on recoverable atomic token to deliver deterministic in order communication. To some extend they are proposing to move back to latices system where each server are a node within the network and act as router for messages. This eliminate switch requirement and looks really neat. However adoption might be difficult due to the ubiquitous Ethernet hardware and also the need to change the underlying communication protocol. Last but not least I do not really know how to efficiently secure and trust messages on such network. [slides] 
• Computer Science video courses : Extensive collection of links to CS courses ranging from introductory to expert in pretty much the full scope of CS subject (DB, distributed systems, etc..) 
• Appdash : Application tracing system for Go, based on Google's Dapper.

Links of the day 20 - 11 - 2014

Today's links 20/11/2014: tracing, messaging, queue, cache is the new ram

• Tracing summit : Tracing Summit 2014 held in Düsseldorf, Germany, on October 13, 2014, video are also available here
• Operating Apache Samza at Scale : how do leverage samza under kafka to scale your messaging infrastructure.
• Cache is the new ram : with the rise of in memory database CPU cache becomes the next frontier ( but what's next ? cpu register is the new cache ?? ) 
• Queues Don't Fix Overload : on why queue are great but not the silver bullet and what are their limitation.
