AuthO- Passkeys

Here is the added authentication from autho , You don’t have to remember the passwords anymore and the keys are stored locally in your device . Try out Passkey

IOT - no code

Configure devices with the TIBBO AppBlocks with no code The business logic is flow chart based configuration for devices. Check out the https://appblocks.io/ Enjoy IOT

Node and Auth0 - Integration

so now we have completed all the steps for integration since we have the node and auth0 as two separate things the integration happens in the app.js we need to modify the app.js with some auth0 code app.js / const http = require('http'); const express = require('express'); var router = require('express').Router(); const { auth } = require('express-openid-connect'); const app = express(); app.use('/', router); const hostname = '127.0.0.1'; const port = 3000; http.createServer(app) .listen(port, () => { console.log(`Listening on `); }); const config = { authRequired: false, auth0Logout: true, secret: 'a long, randomly-generated string stored in env', baseURL: 'http://localhost:3000', clientID: 'QxpAXsXkzy0Vm2VdT6dFFS0VOKdrah67', issuerBaseURL: 'https://dev-bnga041p.us.auth0.com' }; console.log(config) // auth router attaches /login, /logout, and /callback routes to the baseURL app.u

Auth0

You might be wondering what is this auth0 it is used for authentication of you applications could be any apps 1.SPA - Angular , React 2.web app 3.Node here we will talk about the node use case and go with example moving ahead for now if your are not familiar with node dont worry its a funny exercise for now walk with me we dont have to worry too much for authentication as the service is provided from auth0 create your node app install node https://nodejs.org/en/download/package-manager/ choose your os and do the installation once installed check for the version ' node -v ' i assume u have installed so that u wil get the version for now since iam using LINUX this will look like root@strings-desktop:/home/strings/js# node -v v16.13.0 moving on to creating node app for now create a file app.js and paste the contents app.js/ const http = require('http'); const express = require('express'); const app = express(); const hostname = '127.0.0.1&#

Hough Lines

consider the image like this we need to find the lines on this image the basic lines would be horizontal ,vertical and inclined line we will try to use hough to detect using equations ok before that we need to understand the image co ordinate top left is 0,0 assume it is the third quadrant , for better understanding i have drawn a to show how a pixel is calculated from top left pixel arrangement for image this is level zoom of more than 1000 , in real world u cannot see the pixel (1pixel of size 1,1) alright now we can need to see how to find the lines on the first image the triangle on a zoomed in pixel wil look like this ok we will start with the horizontal line calculation since the pixel calculation is in the quadrant i will shift or plot the values in the first quadrant for my calculation when shifted will look like this , for horizontal line calculation the theta of r must be at 90 degrees to the horizontal line u can see the value in diagram r = x cos𝛳 + y sin 𝛳
