create your own search engine using searxng and linux

Leave a comment

The excellent network chuck on youtube made a video the other day about making your own search engine with searxng so i thought id put the steps involved on doing in locally in Linux.

Update our linux installation

sudo apt update && sudo apt upgrade

install docker;

sudo apt install docker.io

install docker compose tool:

sudo apt install docker-compose

navigate to dir where you want to keep searxng, in this example well put it in “/usr/local/”

cd /usr/local

download searxng;

git clone https://github.com/searxng/searxng-docker.git
cd searxng-docker

create secret key;

sudo sed -i "s|ultrasecretkey|$(openssl rand -hex 32)|g" searxng/settings.yml

start up docker containers

sudo docker-compose up

point your browser to;

localhost:8080

Tweaks and settings;

See here for how to change things;

How to create a free SSL cert for your website

Leave a comment

One of the most annoying things about having a website is the fact that you have to pay for an SSL cert and that its an extra it shouldnt be.

I dont need an SSL cert!
100% true this website is only a blog but googles chrome browser no will start warning about sites not having an SSL cert and seriously fuck google for that.

Create and install a Free SSL cert for your website with ZeroSSL in the following video.  Its fairly simple and quick to do.

Getting started with Python and the Django Framework part 1

Leave a comment

So over the christmas holidays ive been keeping myself busy by learning more about the Python language.

Having learnt a few basics i started to try the Django framework which ive seen mentioned quite a lot.  Im reffering to windows mainly in this case see below for more detailed instructions;
https://docs.djangoproject.com/en/2.0/howto/windows/

Step 1:
Install python from the site below and install the necessary version for your Operating system.
https://www.python.org/downloads/release/python-364/

Step 2:
Once you get that installed, verify that python is installed by typing “python” from the windows command prompt;

 

 

 

 

 

 

Step 3:
Install Django framework via command prompt;

pip install django

Step 4:
Create your first project its best to refer to the offical document and tutorials at;
https://docs.djangoproject.com/en/2.0/intro/tutorial01/

From the offical site;

Creating a project

If this is your first time using Django, you’ll have to take care of some initial setup. Namely, you’ll need to auto-generate some code that establishes a Django project – a collection of settings for an instance of Django, including database configuration, Django-specific options and application-specific settings.

From the command line, cd into a directory where you’d like to store your code, then run the following command:

$ django-admin startproject mysite

This will create a mysite directory in your current directory. If it didn’t work, see Problems running django-admin.

Cakephp Tips – Sort Data With the Pagnator Component

Leave a comment

If you wanted to sort a Model by a certain field in this case take the field “created” which is a date. We can simply tell cakePHP to pagnate entries by the order they were created by the following example.

	public function index() {
		
		// we prepare our query, the cakephp way!
		$this->paginate = array(
			'limit' => 20,
			'order' => array('created' => 'desc')
		);
		
		
		$this->Link->recursive = 0;		
		$this->set('links', $this->Paginator->paginate());
	}

CakePhp Tip #6: Displaying items that belong to a user

Leave a comment

cake-logo

Displaying items that belong to a user:

One of the most common things youll do in cakephp is list items that the user should only see. For example a user should just see their “posts” listed or their “articles” etc.

CakePHP has “Magic Find Types” that can help. For example if i wanted to list all the posts of the user_id =12

In my controller i can create an action as follows;

 $myposts=$this->Posts->findAllByUserId(12);

if i wanted to list all posts of the current logged in user;

public function my(){

	$userid=$this->Auth->user('id');
	$this->Post->recursive = 1;
		
	$this->set('posts', $this->paginate('Post',array('Post.user_id =' => $userid)));
		
	//use the index view to render
	$this->render('index');	
 }

To call view this action;

http:://localhost/mycakeapp/posts/my
