A very simple HTTP server in C, for Unix, using fork()

Pico HTTP Server in C

This is a very simple HTTP server for Unix, using fork(). It's very easy to use

How to use

  1. include header httpd.h
  2. write your route method, handling requests.
  3. call serve_forever("12913") to start serving on port 12913

Step 1 - Testing ElasticSearch - spec_helper.rb
# This file was generated by the `rails generate rspec:install` command. Conventionally, all
# specs live under a `spec` directory, which RSpec adds to the `$LOAD_PATH`.
# The generated `.rspec` file contains `--require spec_helper` which will cause this
# file to always be loaded, without a need to explicitly require it in any files.
#
# Given that it is always loaded, you are encouraged to keep this file as
# light-weight as possible. Requiring heavyweight dependencies from this file
# will add to the boot time of your test suite on EVERY test run, even for an
# individual file that may not need all of that loaded. Instead, make a
# separate helper file that requires this one and then use it only in the specs

Clojure deftype, defrecord, defprotocol
  • defprotocol: defines an interface
  • deftype: create a bare-bones object which implements a protocol
  • defrecord: creates an immutable persistent map which implements a protocol

Typically you'll use defrecord (or even a basic map);
unless you need some specific Java inter-op,
where by you'll want to use deftype instead.

Note: defprotocol allows you to add new abstractions in a clean way Rather than (like OOP) having polymorphism on the class itself,

Limit Chrome from eating all the memory and CPU

I was tired of Chrome eating all my laptop resources so I decided to put some limit to it with cgroup.

As I was using Ubuntu 12.04 with support for cgroup, I installed the package cgroup-bin and add the following group to the file /etc/cgconfig.conf:

group browsers {
    cpu {
#       Set the relative share of CPU resources equal to 25%
        cpu.shares = "256";
 }
