Redirect All Requests To Index.php Using .htaccess

In one of my pet projects, I redirect all requests to index.php, which then decides what to do with it:

Simple Example

This snippet in your .htaccess will ensure that all requests for files and folders that does not exists will be redirected to index.php:

RewriteEngine on

RewriteCond %{REQUEST_FILENAME} !-d

Ubuntu 12.04 Ruby on Rails Development Environment

I haven't set up an install guide for the latest ubuntu release, largely because the last set of instructions worked pretty closely with the latest and greatest Ubuntu, 12.04 Precise Pangolin, however when installing today, I found that there were enough differences in the way that I configure my setup to justify an update, so here it goes. Yes, I'm late to the party, but a quick google search didn't find anything that I felt was as complete for my requirements as my previous install guides, so here I go.

As always with my install guides, I have included here is just about everything you'll need (and then some) to get started with ruby on rails development with Ubuntu 12.04 as a platform. These are my settings and preferences, and this is certainly not the only way of doing things, so keep that in mind.

Step 1: Get the repos ready and run updates.

sudo apt-get update && sudo apt-get upgrade

class Foo {
  def bar() {
    ret "it Works!";

}

$f = Foo.new();
print $f.bar();

To open SQLite Things.app database run this command in Terminal.app:

$ sqlite3 ~/Library/Containers/com.culturedcode.things/Data/Library/Application\ Support/Cultured\ Code/Things/ThingsLibrary.db

In SQLite command-line type this query to get your tasks stats:

sqlite> .mode column
sqlite> .header on
sqlite> select zscheduler, zstatus, ztrashed, count(*) from ZTHING where z_ent = 13 group by  zstatus,ztrashed order by Z_pk desc;

ZSCHEDULER ZSTATUS ZTRASHED count(*)

SSH login without password

Your aim

You want to use Linux and OpenSSH to automize your tasks. Therefore you need an automatic login from host A / user a to Host B / user b. You don't want to enter any passwords, because you want to call ssh from a within a shell script.

How to do it

First log in on A as user a and generate a pair of authentication keys. Do not enter a passphrase:

RaVbaker

# ENDPOINT="host.com" ruby app_proxy.rb
# curl -i localhost:4567/capture # => "<TIMEOUT>" or regular response every 2 calls

require 'sinatra'
require 'net/http'

$request_settings = { host: ENV["ENDPOINT"] }
$headers = { "Content-Type" => "application/json" }
$counter = 0

Syntax:

ssh -L localport:host:hostport user@ssh_server -N 

where:

• -L - port forwarding parameters (see below)
• localport - local port (chose a port that is not in use by other service)
• host - server that has the port (hostport) that you want to forward
• hostport - remote port
