How I built a rhymes dictionary ?

camarm — Sun, 09 Jun 2024 12:00:00 +0000

Hi and welcome to this new article !

I've been working hard on my mobile dictionary Remède this last month (I released the 1.2.0-beta version a week ago).

I've added many things but today I will focus on a special functionality.

I've added a rhymes dictionary which is completely running on your phone (or any browser) without an internet connection !

1. - Find data to build a rhymes database

I've searched for open source projects which had already built a rhymes database so I can re-use their database and adapt it for Remède.

After some searches, I discovered that Open Lexicon, a project which provides various open database about words, has enough data to build a rhymes dictionary.

I found the Drime project, which uses Open Lexicon database to generate its own rhymes database. With their documentation, I built my own base and added these rows in a new table of the Remède database.

2. - How it works ?

If you don't know Remède (you can check it out on Github and leave a star), it uses a Sqlite database which is downloaded locally.

Now that I have enough fields about words, how can I build an efficient dictionary ?

First, let's explain how this dictionary is working.

A table rime contains rows (one row is equal to one word) with the fields phon_end, word_end (and more fields like feminine or elide for particular rhymes...).

So for example, to get the rimes of the word bonjour, phoneme \b$ZuR\, we will filter all the words whose phoneme finishes with uR.

The requests will look like

SELECT word FROM rime WHERE phon_end LIKE '%uR'

And you understood the main concept ! Now we can add fields to filter and get more specific results, like in the application.

3. Final look

Yes we have a dictionary but not anyone can use it ! You must know Sql to browse it...

I tried to have the simplest and most understandable interface. For the interface, I use Ionic 7 with Vue 3.

I integrate this functionality as following in Remède:

Description	Screenshot
Searching a word in the rimes dictionary
Browsing rimes
Set syllabes filter

What's next ?

For the moment, some functionalities are missing and the experience is not perfect... I want to add the possibility to choose the "nature" of the wanted rhymes (verb, noun...) and to enhance word finding experience.

Thank you for reading,
Don't hesitate to try Remède (https://remede.camarm.fr, and let me a message about your experience if you want !)
Have nice code !

Remède V1.1.5

camarm — Sun, 19 May 2024 09:21:08 +0000

Hi and welcome to my blog ! Yesterday, last month I released Remède version 1.1.5.

Remède is the free and open source french dictionary which I created !

It has its own database, downloadable and re-usable by all your projects !

Latest challenges

This version resolves many problems encountered previously with the 1.0.0.
The navigation has been completely rebuilt so It implements correctly the back button on any Android device.
The search has also been improved by creating an index table. It makes the search easier because it is now: case insensitive, accent insensitive and special characters insensitive.

Functionalities changelog

This new version includes breaking changes ! Here there are:

New UI/UX on definition page
New revised database
Desktop applications now available for Windows and Linux !
Possibility to choose between light / complete database
Resolved bugs around navigation
Globally enhanced User Experience
Better search experience !

Screenshots

As you can see, I added a landing screen to welcome new users. You can also look at the new UI for definition page.

Welcome page	Definition page

More to come

I don't have so much time to develop Remède at this moment, but this projects have good days to come !

I want desktop application to have their own interface, more adapted to landscape orientation and also running everywhere.
I also want to add a rhymes dictionary which is a functionality I'm working on slowly by my side !

Don't hesitate to leave a star on Github !

Or open an issue...

Running containers on distant host: docker contexts

camarm — Sat, 06 Jan 2024 23:05:46 +0000

Cover from Ruan Bekker blog

Hi, today I will introduce you a docker functionnality I discovered 6 months ago: docker contexts 🐳.

It allows you to build and run your containers on a distant host.

Please note I'm only a docker user, for further informations about contexts visit the official documentation

🧠 Understand contexts

Actually, docker contexts let you manage multiple docker daemons from a single client.

A context has two major informations:

Its name and description
Its endpoint

By default, a default context is created and used. Its endpoint is the local docker sock.

NAME         DESCRIPTION                               DOCKER ENDPOINT               ERROR
default                                                unix:///var/run/docker.sock

The strength of contexts is that you can change from one host to another in only one command !

⚡ Get started with contexts

⚙️ Sever configuration

First, you need to configure your server to enable remote access to your docker daemon.

⚠️ Remote access permit anyone in a network to connect to your docker daemon and, potentially have root access to your server ⚠️

See official documentation

Two methods to enable remote access:

With systemd
With daemons.json

With systemd

1.) Edit the docker.service file and put your own values.

sudo systemctl edit docker.service

[Service]
ExecStart=/usr/bin/dockerd -H fd:// -H tcp://0.0.0.0:2375

2.) Reload changes and restart docker daemon

sudo systemctl daemon-reload && sudo systemctl restart docker.service

With daemons.json

1.) Add the folowing to /etc/docker/daemons.json

{
  "hosts": ["unix:///var/run/docker.sock", "tcp://0.0.0.0:2375"]
}

2.) Restart docker

You should now have remote access enabled. You can verify docker is binding on port 2375 using netstat:

$ sudo netstat -lntp | grep dockerd
tcp        0      0 127.0.0.1:2375          0.0.0.0:*               LISTEN      3758/dockerd

💻 Client configuration & examples

First, you need to ensure that your docker cli supports the context command:

docker context

It should show you a help about contexts

Next, let's create a context

docker context create <context> --docker host=tcp://host:2375

Replace <context> with its name and host by the docker daemons IP.

It should be in the list of contexts outputted by

docker context ls

NAME         DESCRIPTION                               DOCKER ENDPOINT               ERROR
default *                                              unix:///var/run/docker.sock   
<context>                                              tcp://<context-ip>:2375

Default as an asterisk after its name (default *) because it's the currently used context.

To change to the newly created one, just type.

docker context use <context-name>

Now you can run any docker container in the distant docker daemon

docker run -d -it busybox /bin/sh

This execute a shell in an empty container

You should see it in docker ps

docker ps

CONTAINER ID   IMAGE               COMMAND                CREATED         STATUS                          PORTS     NAMES
f4d3674af80a   busybox             "/bin/sh"              2 seconds ago   Up 1 second                               focused_ramanujan

You can verify that it's been running on the distant host by passing which context to use directly in the command:

docker --context default ps

Should not output busybox container
Whereas docker --context <context> ps should !

You have know the rudiments about docker context. Consider referring to the Docker documentation for further informations and explanations.

📈 How I use it ?

Discovering this feature was very helpful in my workflow: I don't need to use ssh to deploy latest versions of my apps anymore.

I just change context, to choose the right server (like databases, microservices, web-prod) and fire docker run -d ....

In parallel i use Portainer, a powerful web UI for docker. It allows me to manage my running containers and check their health right in my browser !

Here are some screenshots of my portainer:

	List of connected daemons

	Lists of containers

I hope you discovered something new,
Have nice deployments,
See you later 👋 !

New project : Remède

camarm — Thu, 04 Jan 2024 22:20:51 +0000

Hi everyone, recently I created a new project named Remède

Remède is a mobile application that provide a french offline dictionary. It's 100% open source and you can download and re-use the dictionary as JSON, SQLite or with the public API.

Actually

Actually, the project is functional but very young. I released the V1.0.0 last week and starting planning future functionalities to develop in 2024.

Version 1.0.0

The version 1.0.0 has following functionalities:

Download the dictionary
Search a word
Add a bookmark on a word
Correct a text (third-party)
Read cheat sheet (no sheet is finished yet)

The goal

The goal is to publish Remède on the Play Store and provide a simple and powerful user experience.

I want to enhance the database with rimes, examples usages. I also want to provide cheat sheet about French grammar and orthography rules. You can contribute on github to support and enhance Remède !

It will be really cool to create a grammar / orthography corrector for Remède instead of using third-parties

Thanks for reading, please consider react to this post and start the repository to give this project a bit of visibility !
Have a nice code,
See you later

Reverse engineering a website to make a mobile application

camarm — Thu, 04 Jan 2024 20:34:31 +0000

A month ago I bought a card called "Avantages Jeunes" (Junior Advantages), made by my region for people below 30 years old.

It can be used in many shops, restaurants, activities... to get promotions. I discovered that there was a web application to look for advantages.

So I decided to use their API to make me a cleaner mobile application, with more functionalities !

The app concept

All you need is your card: just add your card using your credentials.

In the interface you can view suggested advantages, liked ones, your card, your profile and also open a map that show every advantage around you !

There is also a search function.

The reflexion time

Most of the data I needed can be simply got by calling the web application private API.

So I opened HTTPie (a requester), my browser's developer tools on network tab and started trying to reproduce requests.

The map functionality was a bit more complicated... No endpoint can return advantages based on a geo-position.
But I found an endpoint that return a complete list of all advantages, with their address !

I coded a python script that retrieve all the advantages and found their coordinates based on their address (using Gecoding API) and store them in a MongoDb database.

Using MongDb Geospatial 2dsphere index, I have could request database for all the documents which their coordinates field is in a circle of precise center and radius ! MongoDB is so powerful !

The app structure

I used IonicFramework to develop a web based frontend that can be compiled to mobile using a bridge.

The frontend part directly calls the orginal private API except to get advantages around phone's position: it calls a Fastapi server that return advantages in a radius of 1, 5, 10 or 50 kilometers around the position, by using the MongoDb database.

Result

Home page

Map

Search page

And you ? Do you already reverse engineered something ? What was it ?

1 year of Homelab, experience and what's next

camarm — Fri, 03 Feb 2023 17:52:45 +0000

In this article I will explain my experience of my first homelab.

Definitions

vm = Virtual Machine (complete definition)
iso file = Disk / CD image compressed in one file, frequently used to install operating systems (complete definition)
proxmox = Operating system based on kvm software designed to facilitate vm management (Proxmox)

How it started

2 years ago, I met a friend who is fond of servers... Like a virus he contamined me and I started my homelab with a raspberry pi. 6 months after, I bought a Dell Tower Server (T320) and installed Proxmox.

Please note that I am not a professional, i’m only passionate.

Experiences

In this section I will tell you stories that appened with my homelab.

Backups, backups and organize storage

One of my biggest mistakes hopefully appended 2 months after creating my first vms. I hadn’t setuped backup job and I only backuped my vms once…

Results: one of my raid-0 (9yo) disk died and I lost all my server; from the system to vms and backups. Hopefully I had copied all backups to my PC and I didn’t lost all my datas…

After that story I divided server root fs in one disk, iso / unimportant files in another and vms in one redunded disk (raid-1).

I setuped Proxmox backups for backuping each vm everyday and keep a daily, weekly and monthly one.

Caddies for drive bay

When I wanted to add more storage I was confused to didn't find disk drive caddies easily. My server has 8 disk emplacement for disk drives but he only came with 3 caddies (and 3 disks). I bought 5 more that I found on amazone but next time I will ensure that there is no missing pieces like these.

Monitoring

Monitoring tools I use.

Maltrail:
I recommend you to use Maltrail if you would like to ensure your server security...
You will see every connection to your server and it will helps you to write more firewall rules.

Netdata:
Self-hosted or in the cloud, Netdata is the software that notify you of any process, software or hardware problem or failure. You feel safer to know that you haven't to check charts everyday to see problems.

Uptime Kuma:
A classical one: Kuma Uptime. I register all my application urls and activated sms notification to be notified to any application failure. Very useful with his status pages to organize multiple monitors in one public page !

My current homelab setup is not very clean... A lot of useless vm are on my only server... But some important application are running on it and the server is directly connected to my home network so I need a new, fresh and clean, production server isolated in a vlan to make my homelab even secure.

I'm currently looking for rackable servers and Ikea lack table. I want to make a DIY rack built with lack tables !

I will write an article when my homelab will level up !

Thank you very much for reading,
Have nice code,
See you later !
