A very serious security problem has been found in the Linux kernel called “The Stack Clash”. It can be exploited by attackers to corrupt memory and execute arbitrary code. Here you can find how to fix it on Linux.

Prometheus is an open source monitoring tool, which is conceptually based on Google’s internal Borgmon monitoring system. Unlike traditional tools like Nagios, Prometheus implements a white-box monitoring approach: Applications actively provide metrics, these metrics are stored in a time-series database, the time-series data is used as a source for generating alerts. Prometheus comes with a powerful query language allowing for statistical evaluation of metrics.

Many modern infrastructure components have Prometheus metrics built-in, like Docker’s cAdvisor, Kubernetes, or Consul. Moreover, there are libraries for instrumenting proprietary applications in a lot of programming languages.

This talk gives an introduction to monitoring with Prometheus and shows how Java applications can expose metrics for Prometheus monitoring environments and how to instrument applications directly in code, as well as how to expose JMX beans in legacy applications.

LinuxKit is gaining momentum in terms of a toolkit for building custom minimal, immutable Linux distributions. Integration of Infrakit with LinuxKit will help users to build and deploy custom OS images to a variety of targets – from a single VM instance on the mac (via xhyve / hyperkit, no virtualbox) to a cluster of them. In this article, Ajeet Singh Raina will show you how to do InfraKit and LinuxKit work together to build immutable infrastructure.

In this post, you will learn how to write and build a .Net application and then deploy it to Kubernetes.
