Fibur

Fibur is a library that allows concurrency during Ruby I/O operations without needing to make use of callback systems. Traditionally in Ruby, to achieve concurrency during blocking I/O operations, programmers would make use of Fibers and callbacks. Fibur eliminates the need for wrapping your I/O calls with Fibers and a callback. It allows you to write your blocking I/O calls the way you normally would, and still have concurrent execution during those I/O calls.

Example

Say you have a method that fetches data from a network resource:

ruby-1.9.3-p327 cumulative performance patch for rbenv


This installs a patched ruby 1.9.3-p327 with various performance improvements and a backported COW-friendly GC, all courtesy of funny-falcon.


Requirements



You will also need a C Compiler. If you're on Linux, you probably already have one or know how to install one. On OS X, you should install XCode, and brew install autoconf using homebrew.

monitoring: what I want


I've recently shifted from a straight engineering job to a job with a "dev/ops" title. What I have discovered in operations land depresses me. The shoemaker's children are going unshod. Operations software is terrible.


What's driving me craziest right now is my monitoring system.


what I have right now


What I have right now is Nagios.

                How to install QEMU on OSX and install an Ubuntu VM
              
          

        

      

        

  

      

    
Install QEMU on OSX


QEMU requires brew in OSX, so we need to install brew first.


Installing Brew


To install brew we need to have the developer tools enabled in our system. In order to install those tools, we have two options.


    

  1. Download Xcode form the AppStore
    2. 

  2. In your terminal run the following command: xcode-select --install
    3.
