Earnapp: New payment threeshold

Grégoire — Wed, 09 Feb 2022 15:14:11 +0000

I previously writtent about earnapp (in post "How to earn money with your raspberry pi"

A new update about this service (which allows you to rent your unused bandwith to earn passive income, ~ 0,5cts/day): the payment threeshold is now 2$50 (it was 5$ previously).

A faster way to test it ^^

Earn passive income with windows

In a previous article (How to earn money with a raspbery pi), I written about earnapp, which makes earn money with a raspberry pi.

By the way, you can do it with your windows or mac os computer, thanks to HoneyGain (Yeah I know, earnapp can be installed on a computer too...).

The main difference with earnapp is the payment threeshold: on HoneyGain), it's from 20$ (vs 5$ on earnapp).

The other difference is the "cdn" feature: this will allow honeyGain to use your bandwith as a cdn for other clients. Another good point: no need to link a google account.

And all the "how-it-works" it's really simply explained on her documentation. You have to notice that vpn-use is forbidden.

I personnaly started to use it, and the earnings are similar to earnapp (~0,5cts per day): why don't use the both? ;)

Have a look on HoneyGain, and try it!

How to earn money with your raspberry pi

How to earn money with a raspbery pi? It's simple, with earnapp.

What do you need

a raspberry pi (of course ;))
a earnapp.com account

How to install?

At first, register on earnapp. It's free and fast. Next, you have to install the earnapp client on your raspberry pi:

wget -qO- https://brightdata.com/static/earnapp/install.sh > /tmp/earnapp.sh 
sudo bash /tmp/earnapp.sh

After the install, you obtain a device id to copy/paste on your earnapp dashboard.

How does it work

Your raspberry pi will be used as a scrapper by big companies. The more your bandwith will be used, the more you will earn. Nothing to do after install.

I actually earn 0,50€ per day. Not a dream, but on a month, it's best than nothing. You will be paid by paypal, when you reach 5$. I really received the payment :)

Try it on earnapp!

Make sound volume presets for your chromecasts

Sometimes, I tell to Google “Up the volume”, or “Down the volume” on one or several chromecast devices. But the next day, when I want to listen music again, the volume of each device does not match with my mood. I would love to reset all the volumes in few secondes, but I have to open the home application, and reset each device… Boring… With chromecast-reset-volume I can now configure some presets to autoreset the volumes as it was previously: reset all in one cli command :)

What do you need

1 raspberry pi with python3
chromecasts… (of course)

Get source files and install it

$ git clone https://github.com/gpenverne/chromecast-reset-volume
$ make install

Configure it!

Open the config.py and customize your presets. For example:

VOLUMES = {
    'default': {
       '123.123.123.123': 0.5,
       'tv': 0.4,
       'room': 0.1
    }
}

You can write the chromecast name or its ip address (ip address will be faster).

Let’s the magic does the magic :)

$ make apply

And all your configured chromecasts volumes will be setted :)

Functional tests with puppeteer and gherkin scenarios

Grégoire — Fri, 14 Feb 2020 08:52:04 +0000

Read the original article on GKDV

For my custom needs, I was looking for puppeteer functional testing suite. As a php developer, I ordinary use behat to write and play my functional tests. But the project I want to test is python written, and I don’t want to install and configure PHP just to run tests. And what about puppeteer and chrome headless engine? Hey, I had an idea: implement the cool gherkin syntax with puppeteer in pyhton.

About Gherkin

Gherkin is a syntax which looks like:

Feature: Use the rest test suite

    Scenario: We can fetch data from an api
        Given I add these headers:
            | accept | application/json |
        Given I prepare a "GET" request to "/todos/1"
        When I send the request
        Then print the last json response
        And the json node "anythng" should not exist
        And the json node "userId" should exist
        And the json node "id" should be equal to "1"

It’s readable by human, (I mean, by non-developer human :)) and it’s really easy to write.

About Puppeteer

Puppeteer is a Node library which provides a high-level API to control Chrome or Chromium over the DevTools Protocol, and allows to execute actions in a headless (without visible UI) version of chrome. In nodejs, these tests look like:

const puppeteer = require('puppeteer');
(async() => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.setRequestInterception(true);
  page.on('request', request => {
    if (request.resourceType() === 'image')
      request.abort();
    else
      request.continue();
  });
  await page.goto('https://news.google.com/news/');
  await page.screenshot({path: 'news.png', fullPage: true});

  await browser.close();
})();

Understandable by developers, but a bit ugly (and boring to write)… However, using a real browser as chrome to play functional tests has a lot of advantages:

javascript testing
speed
easy to use

Let’s play with pyppettheater

Pyppettheater is one of my amaziiing idea (and it’s what this article is about). In python, the puppether engine can be used thanks to Pyppeteer. And to parse the gherkin features files, we’ll use gherkin-parser.

Install pyppetheater

First, you have to install the chrome headless engine (under ubuntu):

$ wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add -
$ sh -c 'echo "deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google-chrome.list'
$ apt-get -y update
$ apt-get install -yqq unzip sudo python3-pip mysql-client google-chrome-stable
$ wget -O /tmp/chromedriver.zip http://chromedriver.storage.googleapis.com/`curl -sS chromedriver.storage.googleapis.com/LATEST_RELEASE`/chromedriver_linux64.zip
$ unzip /tmp/chromedriver.zip chromedriver -d /usr/local/bin/
$ pyppeteer-install

And install pyppettheater:

$ pip3 install Pyppetheater

You can now run the pyppet_theater binary:

$ pyppet_theater /path/to/your/yml/or/feature/file

Some example of test

Each test suite is a yml file which contains some parameters (if needed):

parameters:
    rest:
        base_endpoint: https://jsonplaceholder.typicode.com

scenarios:
    0: rest/rest-suite.feature

For a REST API:

For example in the rest/rest-suite.feature:

Feature: Use the rest test suite

    Scenario: We can fetch data from an api
        Given I add these headers:
            | accept | application/json |
        Given I prepare a "GET" request to "/todos/1"
        When I send the request
        Then print the last json response
        And the json node "anythng" should not exist
        And the json node "userId" should exist
        And the json node "id" should be equal to "1"

$ pyppet_theater rest.yml

For a frontend test:

For example, in a game/registration.feature file:

Feature: Create an account on a website

    Scenario: As a visitor, I register on the website
        Given I go on "http://my-website.com"
        And I click on "\#signup-link"
        And I type "player6" in field "\#id_username"
        And I type "somepassword" in field "\#id_password1"
        And I type "somepassword" in field "\#id_password2"
        When I click on "\#register"
        Then I should be on "http://my-website.com"

And run it:

$ pyppet_theater game/registration.feature

For mysql tests:

With a mysql.yml file

parameters:
    mysql:
        db_host: 127.0.0.1
        db_user: root
        db_password: root
        db_name: test

scenarios:
    0: "mysql/mysql-suite.feature"

And, in a mysql/mysql-suite.feature:

Feature: Use the mysql test suite

    Scenario: We can select, update and check existence
        Given the row with "id" equal to "1" in table "some_table" should exist
        And the row with "id" equal to "1" in table "some_table" has "some_key" equal to "some_value"
        Then the row with "id" equal to "1" in table "some_table" should have "some_key" equal to "some_value"
        And the row with "some_key" equal to "some_value" in table "some_table" should exist

    Scenario: We can delete and check existence
        Given the row with "id" equal to "1" in table "some_table" does not exist
        Then the row with "id" equal to "1" in table "some_table" should not exist

And run it:

$ pyppet_theater mysql.yml

You can also use the docker image.

A docker image for your cordova and electron projects

Grégoire — Thu, 13 Feb 2020 14:43:49 +0000

Read the original article on GKDV

Each time I need to do a little personal android project (with a light angularjs), I have to remember how to configure android environement, cordova packages, etc.

And recently, I need to generate an electron app. However, cordova and electron use static html rendering logic: how to make it easier?

Using docker

I created a template repository on github: electron-docker-project, which handles android and electron build, and can serve html files using nginx (because modern browsers deny ajax call on local environment). It’s really simple to use, after you based your repository on this template:

Install

$ git clone git@github.com:gpenverne/electron-docker-project.git  
$ cd electron-docker-project  
$ make build # Build the docker image  
$ make install # Install dependencies

Run - electron gui

$ make gui # Launch the electron gui

Generate an android APK (cordova)

$ make android # Generate the android folders  
$ make package # Build android apk (and electron packages!)

Serve static html ui (nginx)

$ make serve-html # Will helpfull to dev

This docker image embed electron and android cordova dependencies: Now, you just have to edit the config.xml file to set the android app’s name, et voilà!

How to totally remove a too big file from your github repository

Oops, you added a too big file on your github repository, and… no way to totally remove it from your history.
