Endless Orange Week: Hack content creators platform (2)

danigm — Mon, 15 Nov 2021 00:00:00 +0100

The past Friday was the last day of the Endless Orange Week. It was a nice and fun experience, and even if I was not able to do as much as I wanted, we were able to make something that "works" in the Hack project.

The Hack Quest editor

The first step to have custom quests on the Hack app was to complete the Ink language support. We started to work on this some time ago, but never completed the functionality.

I worked on that the first three days, updating the ink library and building the missing pieces to be able to load quests from random paths. I've implemented that in a way that the Hack application is able to receive a path to a .ink file, and it's able to build and run the quets.

The Quests are not just the script, but they have some metadata, like title, subtitle, description, difficulty and the card image to show on the interface. To solve that I defined a "custom quest bundle format", that's bassically a folder with:

questId
quest.jpg
metadata.json
quest.ink

So I also added the functionality to import a bundle zip file and export with the quest information.

I created some command line options to use this new functionality:

  --play-ink=FULL_INK_FILE_PATH                 Start a custom ink quest.
  --import-quest=PATH_TO_BUNDLE_OR_INK_FILE     Import a custom ink quest.
  --export-quest=CUSTOM_QUEST_ID                Export a custom quest bundle.

Quest creation interface and the Inky Editor

The first idea was to try to provide a full quest creation experience in the app, but that was too much, so we decided to simplify the way to create quests and depend on the Inky editor external tool. Manuel Quiñones took some time to update the flatpak application with the latests ink version, so we can use to create custom quests.

The Inky editor provides help about the language, syntax highlighting and a simple way to test the script, so it's a nice tool. The main problem with this tool is that it doesn't provide a way to launch it with a file path so it's not possible to integrate with the Hack app.

So at the end, the Quest creation dialog is just a way to define the metadata and to select the Quest ink files from your filesystem. How the ink script is created is a decision to make for the content creator.

The future

We've no time to complete all we wanted to do, and I didn't create a new release, so this new functionality is still not there. But we'll try to do a release soon.

Simon is working on some interface improvements and also on a new tutorial Quest, so we can introduce the Custom Quest creation tool in the same app.

The Character editor

The other part of this week planning was the character editor. Joana did a really nice work designing the application, the initial assets and the user experience, but I had not too much time to work on the implementation. So I spent just one day working on this.

The main idea was to create a new independent app, and then provide a way to integrate with the Hack application and the custom Quest creation dialog. And it'll be a simple application so maybe it could be useful or interesting for other people, it's a fun way to play around and create random faces.

We just created the application Avatar Creator. I created a simple python Gtk4 application and worked a bit on the basic functionality. So right now it loads a list of svg assets and provide the 3x3 grid. You can click on a grid cell and then choose what basic image should go there.

I added the initial set of basic images, created by Joana, to create this funny robot faces, but the format is simple enough to extend with different "avatar libraries" in the future.

Right now it's also possible to export to png, so the app is functional, but it needs a bit more work.

My idea is to work a bit more in the following weeks, when I have some time, on weekends or holidays and at some point, publish it in flathub. And lets see if there are more developers interested on this app so it can grow.

The application is simple enough to be a good place for GNOME newcomers and it's also a fun project to work on. A simple toy app to create faces that could have some potential, some future ideas:

"Smart" random faces generator
Configurable grid: Maybe is interesting to make it bigger or smaller to play around
Programmed simple base image manipulations, like rotation, mirror, color
Animation creation, maybe be able to export to gif

The Endless Orange Week experience

This week was a really nice experience, because we were working in a "personal" chosen project, that we liked and without the day to day meetings, times schedules and other related work stuff.

But that was not all. In Endless we've different teams that work mostly isolated, because we're working on different fields, we've some overlapping, but we work day to day as small teams, and this week we were all using the same slack channel to show our progress, and it was nice.

Maybe now that we're not a big organization with a lot of workers, we can do something like this more often, it's always good to know more about other coworkers and to learn something that maybe it's not related with your main project, but it could be interesting.

I'm really happy that we did this Endless Orange Week, it's sad that it ended too soon, I'm waiting to learn from my coworkers what amazing things they do during this week and I'm looking forward the next year Orange Week!

Endless Orange Week: Hack content creators platform

danigm — Mon, 08 Nov 2021 00:00:00 +0100

This week (Nov 8 – 12) I am participating in Endless Orange Week, a program where the entire Endless team engages in projects designed to grow our collective learning related to our skills, work and mission.

We propose a project, that could be anything, and then work during the whole week, without distraction. I've choosed to work on the Hack project, that's a really nice project that needs some love, because since the past year, we have other priorities, so there's no time to improve the Hack app.

The project: Hack content creators platform

The Hack application is a "Quest" launcher, and each Quest is an interactive learning experience, a guided introduction to some technology or topic.

Quests are just python scripts, with a simple library to expose messages to the user, ask questions, or wait for desktop events, like launch an application, focus an application, etc. And all these Quests are inside the application, and are created by the Hack team and released with a new Hack app flatpak.

The main idea of the project is to provide a simple Quest editor to allow any Hack user to create and share their our Quests.

To have this Hack content creators platform we'll need:

To simplify the way we create Quests, instead of a python script, we'll uses a Domain Specific Language, called Ink. We started to work on this, but we never ended the support.
To create the interface to be able to import and export custom Quests, that could be zip bundles, with the Ink script and some images.
To create the interface to write the actual Quests and save or bundle.
Create some introductory Quest to explain "how to create your own Quests!".
Create an character editor, to be able to "design" new characters for Quests.

The Quest editor

The Quests will be written using the Ink language, and there's something done before. The first idea is to just provide a text editor and some helpful information about the format, and maybe a button to validate. But if there's time we can use something advanced or even integrate the Inky editor.

The Character editor

Each Quest has a main character, and we've five in the Hack app right now, but it could be great to be able to define new ones for custom Quests. That's the idea of this part of the project.

The initial idea is to have a library of character parts to combine, and the editor will allow the user to combine this parts and maybe change colors, to be able to create unique characters for your Quests.

The Team

I'm not working alone in this "side" project during the Endless Orange Week, Simon Schampijer and Joana Filizola will be working on this too, so this is a big task but we've a great team. Let's see how far we are able to go during just one week.

The impact

This is just a project to try to keep alive more time the Hack application, without a lot of effort or a whole team behind it. We are not able to put more content there periodically, so if there's a way to create new content easily and (maybe in the future) a way to publish, it'll be possible to create a community around the project.

And we have also new possibilities, in the near future, we can add some Hack content to the Endless Key, and using the Ink language, so this editor could help to bring more content there easily.

And the final piece, the Character editor, could be an independent application, a nice simple application that could be used to create your character for your profile photo, or to generate random character pics.

I'm a hacker

I've the strength of the one that fails, trains and returns

Some time ago I wrote about my interview process trying to get a job at GNOME. After this blog post was published in the GNOME planet, I received a lot of comments from the Great GNOME community.

This guided me to take a look to the companies that was looking for GNOME developers and after some interviews I finally get an offer to work on Endless.

All the process was online, I've been working from home since 2011 and I want to continue like this. I'm living in Málaga, the south of Spain and I was looking for a remote job.

I've a very nice interview process, talking with developers that I knew about from their contributions to free software and these interviews weren't technical, that's a good thing about the free software contribution and the community, if someone wants to know my technical skills, he only need to look to my gitlab or github and he will find a lot of code. These interviews were personal and with some management questions, to know if I'll fit in the team and the company.

I did the interview to work directly on the Endless OS, in the desktop team, but after some interviews I ended in other team, working with the Endless OS and all GNOME technology, but in the Hack Computer.

The hack computer

The hack computer is an educational project. The main idea is to provide a fully functional computer for kids to be their first personal computer and also provide a way to teach kids to hack.

The computer is a usual laptop, with an Endless OS running, and with some extra applications that try to guide kids to explore, modify and finally hack the computer learning in the process about GNU/Linux, the code and that any part of your software can be hacked to make it better, an introduction to the free software and the great world of open source code that you can modify to learn, play or simply because you can.

The way to guide kids to learn is like a video game, with characters that will appears in your desktop and will guide you with tips and challenges and after each quest completed the kid will learn something, playing with his computer.

If you like this and want to collaborate, we're hiring.

Endless OS

The hack computer is built on top of the Endless OS. Endless OS is based on debian and the desktop is a modified gnome shell, but it's not the usual debian derivative, it's based on OSTree. The main difference is that the root filesystem is read only and updates are managed with ostree, that's like a git repository.

This kind of Operating System is easier to maintain, because the user can't modify the base system, so this means that he was unable to break it. All user applications are installed via flatpak, so are independent of the OS version and because of flathub you can install latests version of apps without the need to update the full operating system.

This is the way that Fedora SilverBlue is trying to follow and is a new way to build and distribute GNU/Linux.

The end of an Era

I've been working in Wadobo since 2011. I created that company with two college friends to try to continue hacking like we were hacking in the Seville LUG SUGUS and earn money from that, and we did it for a long time.

We've been working in free software projects and with free software technology, contributing to the community as much as we can and always trying to free our work.

We created some projects that grow up and follow its own path, like the agora voting system, that Edulix (Eduardo Robles) converts in nvotes.

The self employment was a really good experience. I've been doing was I want for a long time, taking time to contribute to GNOME and other projects when I need it, because I was the one deciding what I want to do. But in the other hand, I've been stuck in the local consultancy market for a long time.

I'm not a business man, I'm a developer and I'm based in Spain, where there is no money inverted in innovation or we was unable to find that money, so we were doing django web apps for a living and spending some time in our interests in the extra time we've. So when I found the possibility to work full time in an innovative project, I've no choice.

We'll try to continue with the Wadobo idea, like a group of people interested in free software and new technologies, maybe this will derive into a Linux User Group or maybe in the future someone takes the initiative and build a business around this again.

Hacking

I'm really happy with this change. Endless OS and the hack computer are really great projects with a lot of bleeding edge technology and a really great group of people, and I'm really exited to be able to work with people all around the world in a project with a global vision.

I don't want to leave the roots I've here with my Wadobo friends and the local community and local technology ecosystem. This is also related with the Endless vision. Spain, and here in the south, in Andalucía, we've a technological breach that we try to fill with free software.

I'll continue working with the Seville University, because they give me a lot and I think it's a talent pool, we only need to guide those students to the GNOME community or to other free software communities out there, to save their souls from the privative software and the dark side.

I'll continue supporting initiatives like the Free Software Contest

By the way, I'll be talking about rust in the Seville University the next Tuesday 5th of March 2019, if you're in Seville, come to talk with me :D
