  • JavaScript: The World’s Most Misunderstood Programming Language – JavaScript, aka Mocha, aka LiveScript, aka JScript, aka ECMAScript, is one of the world's most popular programming languages. Virtually every personal computer in the world has at least one JavaScript interpreter installed on it and in active use. JavaScript's popularity is due entirely to its role as the scripting language of the WWW. Despite its popularity, few know that JavaScript is a very nice dynamic object-oriented general-purpose programming language. How can this be a secret? Why is this language so misunderstood?
  • Dynamic multi-point VPN with OpenNHRP powered linux hub – This post aims to explain how to configure a dynamic multi-point site-to-site VPN over IPSEC between CISCO routers and a Linux machine using the NHRP protocol. […] To support the NHRP protocol I used OpenNHRP, an open-source implementation of the NHRP protocol. To bring up the IPSec tunnels, I used racoon with pre-shared key based authentication.
  • portableR – portableR is a version of R statistics that have all their static libraries within the same folder, this lets run in x86_64 VMs. This project is aimed to run in web servers to build microservices (AWS Lambda) that require R to process data, png chart generation, etc.

  • okvm – Open source KVM over IP technology – The okvm project team in 2005 developed an open source okvm KVM Development Kit – so engineers could cost effectively roll their own integrated KVM over IP control appliances. These okvm KVM Development kits included: one okvm PCI KVM Adapter card the okvm KVM over IP software source code the source information needed to manufacture the okvm PCI KVM Adapter card (circuit diagrams, BOM,PCD layout etc) A number of the KVM PCI cards were produced – sponsored by Opengear. However this project did not find traction in the developer community. So kits are no longer available and development in this branch of the project has stopped. Also Opengear now sells a proprietary KVM over IP solution!

  • Riemann – A network monitoring system – Riemann aggregates events from your servers and applications with a powerful stream processing language. Send an email for every exception raised by your code. Track the latency distribution of your web app. See the top processes on any host, by memory and CPU. Combine statistics from every Riak node in your cluster and forward to Graphite. Send alerts when a key process fails to check in. Know how many users signed up right this second. Riemann provides low-latency, transient shared state for systems with many moving parts.

  • Mail server statistics – The statistics are based on completely anonymous information and were performed using randomly chosen IP addresses. When connecting to a mail server defined as an MX in the domain configuration, it can reply in a different number of ways. It may not be online, or may be refusing connections. Also, it is possible that the server does not respond back with a "220" line within the period of time we wait, nor provide a banner that identifies the type of the software running on it, at all times.
  • Setting up backup mail exchange server with sendmail « Building systems that WORK – Setting up backup mail exchange server with sendmail

    Most systems admin is used to setting up the primary mail server, but many of them (like me) are not used to setup a backup mail server in a regular basis. This is my attempt to create a complete document on setting up a backup mail server and testing it for the dooms day. […]
