I created the first interplanetary exchange platform.

Ayrton — Tue, 10 May 2022 18:00:54 +0000

Good morning !
Yes very ambitious as a title, but that's all.

Let's start with the beginning :

Some time ago, I thought about an optimized commentary for a few points of a rocket launch specification.

After a few weeks of research, I found a working topic regarding payloads in the rocket fairing head.

The difficulty today for space agencies and private launchers is optimizing this space and managing to fit useful volumes into a cylinder several meters high.

Short.

I worked on an optimization topic, pitched my concept to someone in the business, and presented a useful space optimization algorithm. I was then invited to my first astronaut conference.

Then an idea came to me.

The first interplanetary e-commerce platform based on the Stellar Lumens (XLM) blockchain

My ambitions were to facilitate exchanges between the various space service providers.

To do this, I imagined a platform, operating on the principle of the blockchain.

Who can any operator on Earth or from a space station or another planet to be able to order products from a partner.

It could take advantage of the spaces made available by private space companies that sell the payload space in their rocket fairing head.

A problem quickly arises, what do I do when the connection does not exist?

I imagined an application installed on the client (computer, micro computer, smartphone etc...), which is practically autonomous, and which signs the transactions directly via the client.

Once the synchronization has been carried out again, the signature is authenticated by the rest of the nodes of this chain and therefore is validated or not (in the event of cheating) by the blockchain.

This system allows all operators to be sure that the order has been made by the right customer. Fraud is only possible if your secret key is stolen.

I decided to make this work Open Source under MIT license.

Glad to read you about this crazy idea <3

How sports made me a better developer

Ayrton — Sat, 29 Jan 2022 12:37:42 +0000

It's been several weeks since I got into the sport,

I give you the little anecdote that goes well, 65 Kilos in 2018 -> 100 kilos in March 2020.

In fact, I left a job in the restaurant business where I moved around so much and even eating badly I kept my weight of 65 kilos, once I started my new job as an independent developer, I spent 2 years not stop in an office. Without moving, still eating badly. And that was other things.

I didn't fit in any of my clothes anymore and I had to redo a big part of my wardrobe because I was gaining weight. From one month to another I could no longer put my newly acquired things.

Click?
I no longer liked the way I looked in the mirror. And when you start not loving yourself anymore, you enter a complicated phase of your life.

Desire for nothing, loss of energy and motivation, feeling of being useless and heavy. And also happened something that I did not know at all, Weightism .

Whenever I saw someone I hadn't seen in a long time, there was always a hint of the size of my belly. And once I was offered the front seat in the car, because otherwise they would be tight behind.

That was all the trigger. One, I didn't feel well, and two, I was never used to being insulted by others.

I took matters into my own hands in March 2021, a year after my weight gain, I was already at 100kg.

At the beginning of the year, I started doing sports in the gym, Basic Fit type; but the experience was a failure, lack of motivation to go there and not really any results, I didn't really know what to do so I stayed in the comfort of the easy machines.

Then I lost a lot by doing more sport at home, every evening when I got home from the office, but my motivation, like in the gym, quickly flew away, I had however lost nearly 4 kilos during this period.

After that I had moments of breaks, where I clearly didn't care anymore. I then then undertook to find a personal coach not without knowing that it was expensive.

Then I found a great program, indoor cycling. And that's the kif, firstly we're in a group, so it's motivating, secondly the coaches are great, and since it's in a group, it's also less expensive, but personalized all the same, and thirdly there has a huge screen behind which projects videos which gives a semblance of decor it was enough to convince the geek who lies dormant in me, and also music at the bottom to be immersed in the universe! And I've stuck to it ever since I signed up.

I lost 7 (edit 11 May 2022: 22 for now :D) kilos in a month and a half . And the motivation is still more than ever.

So to answer the original question (I know I got a bit lost), How has sport made me a better developer?

It's very simple. I took down the screens, and I devoted myself to other activities. Sport, my balanced diet, spending time with my family. And even if it seems counterproductive it is not at all! On the contrary, when I do my developer tasks, I perform much better. Because sport is also a way to unload, and to restore pep to your body and your mind, it is therefore very beneficial for your daily tasks and your lifestyle.

I also noticed that this sport goal also allowed me to take on new skills. That of going to the end of things. Today each project is realized. And like in sport, even if it's not perfect, I will go after things.

Group work does:

Strengthened the mind
Broken the barriers of shyness (we shout at sport to encourage each other, it feels so good)
Want to give the best of yourself for the group

Today I am at 89 kilos (edit 11 May 2022: 78). I still have a little to lose (I'm 1m73). But I'm proud of what I'm accomplishing, and I feel so much better about myself!

And that too is one of the things that makes me a better developer.

Thanks for reading me!

How I have made an online game in production in less than 1 year

Ayrton — Thu, 23 Dec 2021 13:44:34 +0000

Hi ! My name is Ayrton, I’m french developper from Bordeaux.

I made games since I have 6 years old, and after lot of try of making game, this year I will wanted to make an online game.

Today I want to show at all person who said me, “It’s impossible to make online game alone, blablablabla….)” It’s possible and I show you how.

My first challenge It’s find an easy concept to develop, I will take a look on other success projects. After this, I have choose an online Arena game like Brawl Star but 1 vs 1 and with another camera view.

MVP Concept

To my job, I always use this concept, the Minimum Viable Product, to determine a plan to complete the game, and I etablish a list of functionality essential for the gameplay, but just the minimum.

Tools

Engine

I have use Unity for made the game with C# language, for simple reason;

Fast, easy to learn, Documented, Cross-Plateform, Gameplay requirement satisfied (3D, Online, Controller Support, Mobile etc…).

Link for Unity

3D Tool

Blender is a free and open source 3D modeling tool. I’m not an 3D artist, and he have lot’s of tutorial for beginner.

At start, It’s very hard to do your first item (a table for me :) ) And after lot’s of hour to try, I have made my first character.

Link for Blender

UI Design

XD + Photoshop

Why Adobe XD? I think it’s more simple for made rapid graphics interfaces than Photoshop. Easy for use and easy export.

Link for Adobe XD

Let’s talk about talents.

I have lot’s of talents (no !) but I cant draw, painting, or make music. I’m not an artist, I’m a worker, give me task and I do it.

So when I start to need graphics and sound design, my look take direction to Aurore and Domi, my wife and a friend. Aurore it’s a great artist, she made paint, and Domi has a talent on sound design and it’s a great composer. I demand to they, to make 3 characters and 3 musics . I have proposed to payed they, but they refused and 3 weeks after, all are shipped. Very great person. Love you.

At same time, I have started to code the netcode, I have use an Unity Package who help me to integrate online system inside our game. It’s called Mirror .

1 month later, the netcode works.

Network Infrastructure

At my job, I’m french developper full stack, so, I know how a server work, and how to manage it and monitoring it for the production. But, habitualy it’s web service like API, not Game server engine.

Docker save me. I have use Docker for his capability to duplicate instances. 1 Docker instance = 1 party for 2 player in our game . So if I have 10 users want to play simultanously. I will mount 5 instances, 1 instances take ~1cpu and ~250mb memory when a game is playing. So the duplication it’s essential inside our deployment plan.

I have use Digital Ocean and Scaleway to test our server in development mode on 3 countrys. And it’s look great.

I have made 2 scripts for easy launch new servers and attach they IP automaticly in my APi system who attribute to server an unique ID and know who it’s started or no.

I have use Grafana and Prometheus to monitoring and set alert when problem appear.

Link to Grafana/Prometheus

Integration

It’s the most difficult thing I think, because when you test your game with Cube and Ball you don’t need some animations and game design.

But when I started to integrate character, the difficult for me was to animate it and take it live.

I have started by 4 animations / characters, Idle, Walk, Attack, Dead.

All of character has nearly the same animations, It’s more easy for the script controllers.

And

I have started to integrate environnement and design of arenas too. It take me about 3 month to achieve all of this ! Very difficult …

And like it’s not hard enough, I was do the trick for Online System, so other player can see, other animations. Hell.

From / To

Write blogs posts

Write blogs posts, help me to achieve my work, It’s a good thing for stay motivated and share my experience. See the progress it’s a great thing for considerate the work accomplish;

you can see all the blog posts here:

Simerca Studio
--------------
### Editeur de jeux vidéos
simercastudio.com

Lot’s of test’s after.

After I have tested the game with friend, family, discord members, I start to publish It to App Store and Play Store.

Because in my job I have already post project to App Store and Play Store, I know the requirement to do this.

And after 2 try, It will be posted .

Fantasy Arena it’s available on iOS and Android on production in less than 1 year.

Best Makefile for Docker project (M1 Compatible)

Ayrton — Fri, 16 Jul 2021 07:13:07 +0000

Hi !

Here is the best Makefile ever,

It's now easy to use Registry Gitlab to push your docker images and use repo name as image name.

REGISTRY_ID=$(shell grep gitlab.com .git/config|sed 's/url = https:\/\//registry./g'|sed -e "s/\.git$$//g"|xargs)
TAG=$(shell git symbolic-ref --short -q HEAD|sed -e 's/master$$/latest/g'|sed 's/\([a-zA-Z]*\)\//\1-/g')

build:
    docker build -t $(REGISTRY_ID):$(TAG) .

run: build
    docker run --rm $(REGISTRY_ID):$(TAG) 

dev:
    docker run --rm $(REGISTRY_ID):$(TAG) 

push:
    docker push $(REGISTRY_ID):$(TAG)

pushm1:
    docker buildx build --platform linux/amd64 --push -t $(REGISTRY_ID):$(TAG) .

buildm1:
    docker buildx build --platform linux/amd64 -t $(REGISTRY_ID):$(TAG) .

Realy easy to use:

Build images
make build

Push images
make push

Run images
make run

Test images
make dev`

For Mac M1 Chip, to use for build AMD64 images

Build for amd64 when your use macbook m1
make buildm1

Push for amd64
make pushm1

To Cloud or not to Cloud

Ayrton — Tue, 26 Jan 2021 19:36:22 +0000

Hi fan of Shakespeare !
Thank you for your support on my last blog post:
https://dev.to/simerca/why-i-moved-my-front-with-nuxtjs-to-wordpress-50p2

Last year, I work with the Cloud a major parts of my time.
Aws, Digital Ocean, Azure etc...

Each time, I realize that the cloud should only be used in one situation, if you need a temporary machine to perform certain tasks. But are overall less economical than its physical competitors, that's for me asking the question:

To Cloud or not to Cloud?

Benefits of the cloud

Not to be engaged with an instance
The cost of use (which is also a weak point, we see that later)
Variable power at will
The speed of provisioning
The number of suitable CLI tools

The Benefits of Physics

Low cost ???

Oh wait!
I have no other argument in favor of the physical

Disadvantage of the cloud

At some suppliers, cost surprises
Technical skills inevitable

Disadvantage from the physical

Commitment (often monthly)
Provisioning time
Redundancy not always "native"
Instance not really flexible

So !

This does not necessarily mean that the physical is a bad option, moreover in most cases I will advise to go for the physical for your companies. Or if you don't have any linux server skills, you can use SAAS services (Vercel, Heroku, Netlify ... etc)

If you have arguments to reinforce or counter what I'm saying, don't hesitate to tell me about it in the comments!

Why I moved my Front with NuxtJs to Wordpress

Ayrton — Sat, 23 Jan 2021 21:48:15 +0000

Hi everyone !
Thank you for your support on my last blog post:
https://dev.to/simerca/deploy-postgres-with-replications-database-in-a-minutes-with-terraform-infrastructure-as-code-59ef

Yesterday and after many years work with NuxtJS, VueJs, React etc... I moved my website to Wordpress...

WHY ??!! (traitor)

Three reasons :

1 - SEO

I'm developper, not an SEO addict or daily user, I just want the minimum basic for my app should appear to google, but with NuxtJS or VueJS, We should do many configuration to have the best SEO result.

Wordpress = Install Yoast SEO Plugin and it's done, and automaticly on all your existing/new post/pages

2 - Front Builder

I'm backend developper, the front design is not my speciality, and when I want to make beautiful landing page with Nuxt, Vue or React, I need to write all animations, all basic containers etc.etc.. very boring !

Wordpress = Install Theme + Elementor or Divi Builder and it's done ! With Visual Builder tool ! Great !

3 - Async

With NuxtJS, VueJs or React, when you want to show something dynamicly on your page, you need to do somme http calls to your api, (Nuxt has server side rendering but it's same thing to have Php server)

Wordpress = PHP is server side rendering, no async method to load page, perfect for landing .

So, I have my Marketing Landing page on
mydomain.com

And my App on
app.mydomain.com

Say me if you have more arguments or if you are totally in disagree!

Love !

Deploy Postgres with replications Database in a minutes, with Terraform (Infrastructure as Code)

Ayrton — Fri, 22 Jan 2021 21:23:27 +0000

Hi everyone !

So many thanks for your supports in my last blog post:
https://dev.to/simerca/use-native-gps-with-vuejs-for-ios-and-android-1kk7

Today ! It's a great time for you !
I'will show you how to deploy Postgres database in a minutes with Terraform and AWS, with Primary / Replica and Hourly backup !

So first, whats is Terraform ?
Terraform it's a tool for Infrastructure as Code, it's very simple to use it, for exemple, you just write the configuration of you need and execute it with one command like :
terraform apply

First install Terraform:
https://learn.hashicorp.com/tutorials/terraform/install-cli

Next, start the configuration files

please use my public repo in gitlab:
git clone https://gitlab.com/Simerca/terraform-postgres

Next, see the first file and edit with your own configuration
variables.tf

// Default AWS Access Credentials
variable "access_key" {
    default = "****"
}
variable "secret_key" {
    default = "*****"
}
variable "region" {
    default = "eu-west-3"
}
variable "bucket" {
    default = "bucket"
}
variable "aws_ami" {
    default = "ami-00798d7180f25aac2"
}
variable "aws_type" {
    default = "t2.micro"
}
// Other Configuration
variable "workspace" {
    default = "user"
}
variable "password" {
    default = "*****"
}

So next see the main file
app-instances.tf

/* Setup our aws provider */
provider "aws" {
  access_key  = "${var.access_key}"
  secret_key  = "${var.secret_key}"
  region      = "${var.region}"
}

resource "aws_instance" "primary_1" {
  ami           = "${var.aws_ami}"
  instance_type = "${var.aws_type}"
  security_groups = ["${aws_security_group.swarm.name}"]
  key_name = "${aws_key_pair.deployer.key_name}"
  connection {
    host = self.public_ip
    user = "ec2-user"
    private_key = "${file("${path.module}/id_rsa.pem")}"
  }
  provisioner "remote-exec" {
    inline = [
      "sudo yum update -y",
      "sudo yum install git -y",
      "sudo amazon-linux-extras install docker -y",
      "sudo service docker start",
      "sudo curl -L https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose",

  key_name = "${aws_key_pair.deployer.key_name}"
  connection {

    private_key = "${file("${path.module}/id_rsa.pem")}"
  }
  provisioner "remote-exec" {
    inline = [

    ]
  }
  tags = { 
    Name = "${var.workspace}-replica"
  }
}

So ! Try to understand how it works

Step 1 :

Use the variable to set the configuration, very simple to do this.

provider "aws" {
  access_key  = "${var.access_key}"
  secret_key  = "${var.secret_key}"
  region      = "${var.region}"
}

You can use environment variable with the schema :

TF_VAR_access_key=XXXXXX terraform apply

Step 2:

Launch instance and basic configuration with set of command lines

resource "aws_instance" "primary_1" {
  ami           = "${var.aws_ami}"
  instance_type = "${var.aws_type}"
  security_groups = ["${aws_security_group.swarm.name}"]
  key_name = "${aws_key_pair.deployer.key_name}"
  connection {
    host = self.public_ip
    user = "ec2-user"
    private_key = "${file("${path.module}/id_rsa.pem")}"
  }
  provisioner "remote-exec" {
    inline = [
      "sudo yum update -y",
      "sudo yum install git -y",
      "sudo amazon-linux-extras install docker -y",
      "sudo service docker start",
      "sudo curl -L https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose",
      "sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose",
      "sudo chmod +x /usr/local/bin/docker-compose;",

  }
  tags = { 
    Name = "${var.workspace}-primary"
  }
}

Be carreful to this line

private_key = "${file("${path.module}/id_rsa.pem")}"

Yoo need to create new SSL key for access to your instances

ssh-keygen -t rsa -N "" -b 2048 -C "assignment"
ssh-keygen -y -f ~/.ssh/id_rsa.pem > ~/.ssh/id_rsa.pub

After,
The command line execute command in order.

Install dependencies
Install docker
Docker run some containers

We run this set twice, 1 primary, 1 replica (master/slave)

Step 3

Open security group

In other file we have :
security-group.tf

/* Default security group */
resource "aws_security_group" "swarm" {
  name = "swarm-group-${var.workspace}"
  description = "Default security group that allows inbound and outbound traffic from all instances in the VPC"

  ingress {
    from_port   = "0"
    to_port     = "0"
    protocol    = "-1"
    cidr_blocks = ["0.0.0.0/0"]
    self        = true
  }

  ingress {
    from_port = 22
    to_port   = 22
    protocol  = "tcp"
    cidr_blocks = ["0.0.0.0/0"]
  }

  ingress {
    from_port = 5432
    to_port   = 5432
    protocol  = "tcp"
    cidr_blocks = ["0.0.0.0/0"]
  }
  ....

Here we open the needed port to access on our Postgres

Lets Try !

First try your configuration (it's just a test)
terraform plan

Next, you can use this exemple command line to launch Postgres instance inside your AWS account :

TF_VAR_access_key=XXXX TF_VAR_secret_key=XXXX TF_VAR_user=DBUser TF_VAR_password=SomePassword terraform apply

This command launch:

2 Ec2 instances (Primary /Replica)
2 PostgresSQL Database on port 5432 and with the user : DBUser and password : SomePassword
2 Monitoring container with Grafana
2 Hourly backup on S3 Bucket(Primary to Replica)

and when you want to destroy all instances

terraform destroy

very simple no ?

Some pub ?

If you don't want to use your mind, you can try my deployment tool, to deploy Postgres with replications and Monitoring in a minutes

Use Native GPS With VueJS for iOS and Android

Ayrton — Wed, 07 Oct 2020 18:34:37 +0000

Hi people who want to conquer the planet! Human btw

Today I show you how to use GPS inside your VueJS app of destination to Android or iOS.

If you can’t understand how VueJS can be integrated inside mobile app take a view on my last post !

Mobile App in 5 minutes with VueJS

Did you know Capacitor ?

Capacitor is a library from develop by Ionic and It make a join with JavaScript code and Native Mobile functions.

Today we speak about the GPS but Capacitor have lots of functionality take a look here

https://capacitorjs.com/docs/getting-started

The first thing is to init capacitor inside your project application

npm install @capacitor/core @capacitor/cli

Next run

npx cap init

Dont forget to change build dir inside the capacitor.config.js

NOW

Inside your application when you want get GeoLocation from user,
You do use


import { Plugins } from '@capacitor/core';

const { Geolocation } = Plugins;
export default {

methods:{
  async getCurrentPosition() {
    const coordinates = await Geolocation.getCurrentPosition();
    console.log('Current', coordinates);
  },
  watchPosition() {
    const wait = Geolocation.watchPosition({}, (position, err) => {
    })
  }
}
}

Now you can look on variable coordinates, has you can see is there an object like

{
speed:0, // on km/h
latitude:x,
longitude:x,
accurate:x // on metters
}

It's directly work on you browser and you can build it with Capacitor into a Mobile App.

You can enable high accurency with this option

enableHighAccuracy: true;

exemple

const wait = Geolocation.watchPosition(
{
enableHighAccuracy: true;
}, (position, err) => 
{
console.log('error',err);
})

Very easy to use in your application !
