If you have a VPS or Dedicated server and have access to SSH, then ssh to your server and cd to the public_html directory of the user who’s having the problem

cd /home/username/public_html

then run the following command to fix the permission problem

chown username.username * -R

replace username with the actual cPanel username

and if you are on a shared hosting and don’t have SSH access, you might want to refer your hosting company to this page

You will need:
Python installed
Sqlite3 Library

Sqlite comes with a Command Line Shell for creating and managing databases

Create an empty sqlite database
If you are on windows go to Start > run , type CMD ad the command line window will appear, make sure you have an empty folder created wherever you want to build the program, in my case I created a folder on desktop called “program”, if you did like me then in windows command line windows type

cd Desktop/program

At a shell or DOS prompt, enter

sqlite3 mydb

that creates an empty sqlite3 database, now lets create a table to store notes

create table mynotes(note varchar(50) );

the above line creates an empty table inside the database “mydb”

Python file
Create an empty file inside the same dir and name it prog.py
and paste the following inside it (don’t worry I will try to explain most of it):

from Tkinter import *
import sqlite3
 
class Program:
    def __init__(self, master):
        frame = Frame(master, width=80, height=50)
        frame.pack()
 
        self.text = Label(frame, text="")
        self.text.pack()
        self.text.grid(row=0, sticky=W, pady=10, padx=10)
 
        self.TextField = Entry(frame, width=45)
        self.TextField.pack()
        self.TextField.grid(row=1, rowspan=2, sticky=W,  pady=5, padx=10)
 
        self.btn = Button(frame, text="Add note", command=self.add_note)
        self.btn.pack()
        self.btn.grid(row=3, rowspan=2, sticky=W, pady=10, padx=10)
 
        self.showbtn = Button(frame, text="Show Notes", command = self.show_notes)
        self.showbtn.pack()
        self.showbtn.grid(row=3, rowspan=2,  pady=10, padx=80)
 
 
        # create an empty Tkinter listbox
        self.content = Listbox(master, width=50)
        self.content.pack()
 
 
    def add_note(self):
 
        # if texfield is empty
        if self.TextField.get() == "":
            # then set text label text
            self.text["text"] = "Please type a note"
        else:
 
            # everything is ok lets get the typed note
            item = self.TextField.get()
 
            # create sqlite connection            
            conn = sqlite3.connect('mynotes')
            c = conn.cursor()
 
            # insert a row
            c.execute("insert into notes (mynote) values (?)", (item,))
            conn.commit()                  
 
            # close connection
            c.close()
 
            # clear input
            self.TextField.delete(0, END)
 
    def show_notes(self):
            conn = sqlite3.connect('mynotes')
            c = conn.cursor()
 
            # select all entries from database
            list = c.execute("SELECT * FROM notes")
            conn.commit()
 
            # list has an array so lets loop the array and insert each item to
            # our listbox
 
            for row in list:
                    self.content.insert(END, row)                    
            c.close()
 
 
 
root = Tk()
application = Program(root)
root.mainloop()

Lets explain the code above

def __init__(self, master):

function for initialization.

Creates the main frame

it creates a label where we can put any text we want, we created a label to show a message if field left empty
row , sticky, pady, padx control the position of the label

Creates a text field, you may note there is "frame" as first argument, that's the name of Tkinter frame we want the text field in

Creates a button, text argument is the text displayed on the button, command is the function to run when you click that button

Creates an empty Tkinter listbox (thats where we will display sqlite3 contents)

where item = self.TextField.get() we are getting the text typed into Textfield.
where self.TextField.delete(0, END) we are reseting the field.
sqlite3.connect('mynotes') creates a sqlite connection to mynotes (the database).

If you don’t know what is Json, a Json string looks like this

{
“name”: “John Smith”,
“Age”: “30″,
“username”: “Jsith”,
“location”: “Chicago”
}

Our search engine will be 2 pages

index.html
search.php

index.html content

<form action=”search.php” method=”post”>
<input type=”text” name=”keyword” />
<input type=”submit” value=”search” />
</form>

in the above step we build a basic html page with a form that contains text field and submit button to submit the form to our search.php, then once a user type a keyword and hit submit we want to take that keyword and search facebook public posts suing their graph API.

Now in search.php We need to catch the submitted keyword from index.html

$keyword = $_POST['keyword'];

The graph url which will return a JSON string is https://graph.facebook.com/search
the url accepts many parameters but we will use the basic ones such as type and q (query)
you can see what the JSON results would look like before we parse them with PHP here:
https://graph.facebook.com/search?q=hello&type=post
Now lets set the graph url we will be opening with php

// set graph url
$graph_url = “https://graph.facebook.com/search?”;
// add parameters to graph url
$graph_url .= “&type=posts”;
$graph_url .= “&q=$keyword”;

in the above step we have a prepared graph url with type parameter and q parameter, the q parameter is the keyword we want to search for and type is the kind of contents we need, we are going to search for posts, aren’t we?
Now that facebook graph url is ready with the keyword we want to search for, lets have php open it so it returns the JSON results

$results = file_get_contents( $graph_url );

$result will be the variable holding the JSON data returned by Facebook Graph, We now need to parse JSON and display it as readable text or HTML content, We will parse it using php function – json_decode() -

$json = json_decode($results);

the json_decode() function in the way used above converts the JSON string into accessible objects, We will need to do a foreach loop to access those objects and print them, lets do that now

foreach( $json->data as $show ) {
echo $show->from->name . “\n”;
echo $show->message . “\n”;
echo $show->created_time . “\n”
echo “<hr>>”;
}

Now you might be wondering why used $json->data and not $json alone, the answer is because all the returned results in JSON are inside an array called “data” and also you may have noticed to show the name of poster I’m doing $json->from->name is because “from” is an array and name is an object inside that array you can see how it looks like here https://graph.facebook.com/?q=hello&type=post, In this tutorial I’m only showing name of person who made the post, message which is post content, created time is the timestamp of the post date you can access many more such as Facebook user ID , description, comments count etc. By simple doing $show->xx where xx is the object name! I hope this helps you in your next Facebook app project! you can what we have created in action here

search.php all together will look like this

$keyword = $_POST['keyword'];
$graph_url = “https://graph.facebook.com/search?”;
$graph_url .= “&type=posts”;
$graph_url .= “&q=$keyword”;
$results = file_get_contents( $graph_url );
$json = json_decode($results);
foreach( $json->data as $show ) {
echo $show->from->name . “\n”;
echo $show->message . “\n”;
echo $show->created_time . “\n”
echo “<hr>>”;
}

First you will need to load the date helper

Now lets use the function in any of our controllers

That will outputs something like

Note that 1326927423 is a UNIX date format, see this page to learn about date formats and how to convert them.

The first thing you should do if you are on a openVZ VPS is asking your vps provider to enable TUN/TAP device for you or just give them the following commands to run on their hardware node
to enable TUN/TAP

to enable IP tables if necessary

where 101 is your vps CID.

Now ssh to your server, if you are on Linux (Ctrl + t) to open terminal and type inside

Where xxx.xx.. is your server IP address, it will then ask for root password just type it and hit enter to login to your server.

If you are on windows then use putty to connect to your server.
now that you’re logged in, run the following command to download openvpn access server installation script
for centOS 32bit do this

for centOS 64bit do this

run Openvpn Access Server installer for (32bit)

run Openvpn Access Server installer for (64bit)

it will take anywhere between 4 minutes and 10 minutes, it will create the master username(openvpn) so once done lets change the user “openvpn” password by running this

choose a password, type and confirm it and that is it! you got openvpn access server installed and ready, to login to openvpn access server admin, the url would be something like this

where xxx.xxx.xxx is your server IP address, and make sure the url is starting with https, the user name would be openvpn and password would be the one you have chosen in last step.

and to login as a client the url would be

the first time a client connect to openvpn access server, he may be asked to download openvpn connect client.

then lets SSH to server first, I’m connecting from my Ubuntu desktop, if you are on windows then look at putty a cool ssh client for windows computers

ssh root@xx.xxx.xx

in this example we are going to host the domain name “www.example.com”.
now that you are logged in to server, lets change dir

cd /etc/apache2/sites-available

let’s create a configuration file for www.example.com
NOTE: I will be using “vi” its a text editor that comes with Ubuntu and you can use it in any ssh session, if you don’t like it then install yum or just sftp to server and work with a GUI

vi www.example.com

Now that vi has create the virtual host file , lets copy and paste the following inside that file
TIP to paste the following in the file we created/opened in the step above, press i then mouse right click

ServerAdmin name@example.com
ServerName example.com
ServerAlias www.example.com
# Indexes + Directory Root.
DirectoryIndex index.html
DocumentRoot /var/www/example.com

Now lets save that file, press Esc 2 times then type:

:wq

Now we have to enable www.example.com on the server, to do that issue:

a2ensite www.example.com

Great! Now you only need to go to /var/www to create a home directory for example.com, remember in the steps above we created a configuration file that has a virtual host for example.com? in that file we also added something like DocumentRoot ?
thats where the domain home directory will be so lets create it.

cd /var/www
sudo mkdir example.com

Lets reload apache

service apache2 reload

Now remain to add an A record to example.com wherever you have it registered, here is a guide on how to do that on Godaddy

That is it! just upload the website files to /var/www/example.com and you will be able to access them by visiting wwww.example.com

ImportError: No module named tkinter

Python has many different GUI toolkits, of which the most standard is Tkinter which comes with Python but I was unable to get tkinter to work so I Googled a bit and found some articles claiming that running the following commands can fix the problem

sudo apt-get install tk-dev

or

sudo apt-get install python-tk

But it really did not solve the problem and I kept getting

ImportError: No module named tkinter

Until I found out that this is wrong

import tkinter or tkinter.Tk() etc…

but you must always use capital “T” in tkinter Like this:

import Tkinter

app_win = Tkinter.Tk()

that solved my problem and I hope it solves yours!
Oh my python version is 2.7.2+

if you have Ubuntu and Windows side by side

Boot with ubuntu then go to your Home folder and on the left you will see under “Devices” the hardisk your windows installation is on, Click on that and go to Documents & Settings > Your_user_name > Application & Data > Thunderbird > Profiles

there should be a folder named something like  xxxx.default copy that folder and go back to your Ubuntu home directory press Ctrl+h to show hidden folders and then find a folder called .thunderbird open it and paste there the folder you copied in the steps above

Wait…. Do not leave that folder yet.

open up the file called profiles.ini you should see something like this:

[General]
StartWithLastProfile=1

[Profile0]
Name=default
IsRelative=1
Path=xxxxx.default

change the xxxxx.default to the copied folder’s name and start Thunderbird and you should see all of yours emails there.

if you don’t have Ubuntu and Windows side by side then you will need to put that folder on a USB stick and use it in Ubuntu
