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

# 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

Integralist

• 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,

• Ghost Methods
• Dynamic Proxies

• Kernel Method
• Flattening the Scope (aka Nested Lexical Scopes)
• Context Probe
• Class Eval (not really a 'spell' more just a demonstration of its usage)
• Class Macros

Rebase "web-123-my-branch" onto master:

if you're the only person who is working on a branch...

$ git checkout web-123-my-branch # make sure you're on the right branch
$ git fetch # update remote refs
$ git rebase origin/master # perform the rebase onto the current state of master
  # for each conflict, edit file, resolve conflicts, git add -u <file>, git rebase --continue
$ git push -f origin web-123-my-branch # overwrite remote branch with newly rebase branch

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";
 }
