React native with Android – Fix : Device unauthorized

15/02/2022 Nicolas Baptista 0 Comments

Check developer is enabled in the phone settings

One reason your phone is not detected is that you don’t have enabled the developer mode in the Android Settings.

Check the connected android devices with adb devices

Now you can check if your phone is connected with adb devices

sh-3.2# adb devices
* daemon not running; starting now at tcp:5037
* daemon started successfully
List of devices attached
CBAA004484J41536762     unauthorized

Authorise your device with adb kill-server and adb devices

If your phone still not asking anything while connected, you can force the adb service to restart like that:

sh-3.2# adb kill-server
sh-3.2# adb devices
* daemon not running; starting now at tcp:5037
* daemon started successfully

Then now you should be able to see a message on your phone asking if you authorise the computer.
Now you should be able to do your react-native run-android or yarn android

Start Google Cloud instance VM from a shared image from another Project / Organization

11/02/2022 Nicolas Baptista 0 Comments

If you have multiple projects or organization and you want to clone a machine that is already configured, you can create an image of the instance of the machine.
But, you will have to share the access to the external project and organization.
Here is how to do it :

Share the image to the organization in the Images and in IAM

In both IAM and Image (VM) you will have to share the access Compute Image User

Start the VM using the shared image from another project / organization

gcloud compute instances create INSTANCE-NAME --image SHARED-IMAGE-NAME --image-project PROJECT-NAME --zone ZONE --tags http-server

INSTANCE-NAME : Name of the VM instance you are creating (that will appear in the VM list)
SHARED-IMAGE-NAME : The name of the image you shared to the organization
PROJECT-NAME : The name if the project where is the image you shared to the organization
ZONE : The geographical zone of the VM

Now the machine is started from an image from another organization and project !

Mac M1 : react native iOS mobile app on Simulator

07/02/2022 Nicolas Baptista 0 Comments

I decided to make an article because I spent almost 5 days on this problem, and I don’t want it never happen. So let me help all the people that can be in the same case of me.

– You have a Mac M1 running on ARM 64 architecture
– You are working on a React Native or Swift project with Xcode

Exclude the ARM architecture in the Podfile

Add the following lines in the Podfile (/ios/Podfile) :

    post_install do |installer|
      ## FIX MAC M1 ARM
      react_native_post_install(installer)
      installer.pods_project.build_configurations.each do |config|
        config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64"
      end
    end

You should check that there is only one “post_install” in the file, if there is not you can add it at the end of the file, if there is already “post_install” somewhere, just put the instructions to exclude the architecture ARM 64 at the end of the “post_install” section.

Dependencies with CocoaPods

In the /ios folder of your React Native project, you should run the following command to build all the dependancy in the /Pods folder :

sudo arch -x86_64 pod install --allow-root

or, you can also use pod-install to be sure all is installed:

npx pod-install

In case of error: Delete /Pods folder, delete Podfile.lock and start again. In case of error of dependancies in node_modules, delete node_modules and run yarn.

Exclude the ARM architecture in Xcode

Now, you should also exclude the architecture in the project settings in Xcode :

Exclude the architecture “arm64” in Project > Build Settings > Architectures

Then if you start the react native project on Simulator it should works !

How to solve error SQL Import Google Cloud

25/01/2022 Nicolas Baptista 0 Comments

Is it possible that when you try to import a backup of your MySQL database on Google Cloud, you have the following error :

We are trying to import a backup in Google Cloud SQL

error: exit status 1 stdout(capped at 100k bytes): stderr: ERROR 3546 (HY000) at line 26: @@GLOBAL.GTID_PURGED cannot be changed: the added gtid set must not overlap with @@GLOBAL.GTID_EXECUTED

To solve the problem, open the SQL file with text editor and search the error “@@GLOBAL.GTID_EXECUTED”

After modifying the *.sql file, you should be able to import successfully :

Renew automatically HTTPS SSL certificates with cron and Certbot

25/01/2022 Nicolas Baptista 0 Comments

Use the command crontab -e to edit the crontab (recurring tasks), and insert the following line:

0 0 1 * * /usr/bin/certbot renew --pre-hook “service nginx stop” --post-hook “service nginx start” --quiet > /etc/letsencrypt/renewals.log

It will renew all the certificates, the 1st of each month (0 0 1 * *), and will stop nginx before the renewal and start nginx after the renewal so it can works.
It will work on all the linux servers.

La plupart des idées de Robert Kiyosaki dans son célèbre livre “Père Riche, Père Pauvre” se résume dans plusieurs schéma qui résume les différents engrenages des personnes des différentes classes. Notamment au niveau de leurs “actifs”, leurs entrées d’argents, et leur “passifs”, leurs dépenses.

On peut qualifier l’auteur comme réaliste ou fataliste, donc ayez un esprit assez ouvert et critique pour comprendre votre situation et l’accepter, pour ensuite pouvoir évoluer vers la situation que vous souhaitez, par exemple l’indépendance financière et ne pas dépendre des systèmes de retraite de l’état.

Import / Export MySQL Workbench tables in Google Cloud SQL database

14/11/2021 Nicolas Baptista 0 Comments

If you have a database on Google Cloud and you want to import and export some tables to another database, you will need a database explorer to export your .SQL backup.

Export the tables you want in database

Google Cloud interface only allow to export all a database or a specific database, but not tables

As you can see you don’t have the option to select tables.
To do so, you will have to connect the database with a SQL explorer.
In MySQL Workbench you should go in Server > Data Export

Then you should be able to select the tables you want

*select* **Export to Self-Contained File** *to have a .SQL file*

Import the SQL file to Google Cloud

You will need to upload the SQL file to Google Cloud in order to import it. In order to do it, go to Google Cloud > Cloud Storage, create the bucket if it doesn’t exist yet :

create the bucket dedicated for **SQL**, with **random** numbers, to have a **unique** name

Upload the SQL file generated by MySQL Workbench

Then, you can go on Google Cloud > SQL > Import

Select the SQL file from the bucked and select the database you want the tables to be imported

And then you should have imported successfully the tables on the selected database. You should check it in Operations

In case of errors, check the error in Operations, and modify the .SQL file with a text editor, search the error in the SQL file and remove the lines, and repeat the process (upload it again to Google Cloud Storage and import the SQL file again)

Public Images for your React / Angular app on Google Cloud

20/10/2021 Nicolas Baptista 0 Comments

We often need images in our React or Angular app, but putting them in the project is not clean.
So we can use Google Cloud with Cloud Storage for the images on your app.

There are many advantages of using Cloud Storage to expose public images :
– Real time maintenance (upload, delete, change, …)
– You don’t need any commit on your git (if you commit images on your Github / Gitlab for example)
– Clean project, only code files
– Light project repository to commit, images are heavy quickly

Create a Bucket

First, you need to create a Bucket (it’s like a big folder) if you don’t already have one.

Switch to Uniform access control

Then, to make your Bucket public, go to the Permissions tab, and change the access control to Uniform :

You should click **Switch to Uniform**, so you don’t have to make public each file one by one

You can see, if you upload your first image, that it’s not public yet

Add public access using by adding a Reader role for allUsers

You can then add the access of **Object Reader** to **allUsers**

Then you can see it’s **Public to Internet** and you are able to copy URL

You can now use you image anywhere, it’s on internet and anyone can see it with the URL, so you can use it to store images for your React / Angular app, all images will work.
