create your own search engine using searxng and linux
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;

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,
cdinto a directory where you’d like to store your code, then run the following command:$ django-admin startproject mysiteThis will create a
mysitedirectory in your current directory. If it didn’t work, see Problems running django-admin.
Cakephp Tips – Sort Data With the Pagnator Component
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
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
