Nicely done!
Thanks a lot!

Hello! What site do you go to to get these pop ups? I don't publish very often on Hacker news

I wanted to create automated lighting that would add a ‘wow’ factor and be fun and very different.

One of the main issues we had with the Luos microservices orchestrator, beyond the open source project itself, was to understand the expectations and problems faced by developers working in the embedded and edge domain. We needed to build a community to exchange with them, allow them to learn and help each other. So we decided to do an A/B test by trying them both.
Re:Embedded programming is like web development on Wednesday November 09, 2022 @12:28PM (#33534897)
First, Thank you for this article.

I think embedded system engineers should be more open to learn from other programming domain and try to catch the good things to apply it in the embedded world. For sure there is some specific constrainsts in the embedded world limiting the usage of web tools. But I agree with you at a system point of view there is a lot of similarities and we could solve a lot of problems by applying the same strategies.

I'm an embedded system engineer specialist on robotics. Each robot I worked on have multiple boards (my personal record is 35 boards). Scaling a system like that is an absolute nightmare. That's why I'm now working on an open-source microservice orchestrator dedicated to critical real-time embedded systems. The concept is to follow the metodologies used to scale complex web applications thanks to a tool able to deal with embedded system specificities. You can find my Luos lib here : https://github.com/Luos-io/luos_engine Let me know what you think about it.

Re:Ask HN: Is it a good time to start freelancing? on Monday November 07, 2022 @12:01PM (#33508575)
External variables such as pandemic or inflation do not directly affect the freelance community because each company/clients manages its accounts differently. The few keys are word of mouth, networking and the quality of the work offered. Obviously the price issue often comes into play but it is more dependent on your competitors than on "undesirable" and uncontrollable effects.

I think that developing devices should be more accessible. Software is flexible, but hardware hinders us. We must find a way to make embedded as flexible as software to unleash developers' superpowers.

With Luos, we want to give a helpful, free, opensource, and easy-to-use solution to solve and spread it to the embedded domain.

You are right, however many tools are starting to think about this issue. We tested the beta of a tool (https://open.crowd.dev/luos) and they are developing a feature that allows you to publish a mini-website that indexes the most interesting content published in the community. And as seren said, Discord has also recently released a Forum feature to better categorize topics and allow members to quickly find and exchange :)

Thank you for this comment, I will continue to share articles in this area since I am also passionate about it

Show HN: I made and automated my house stairs

Hello all!I wanted to create cool animations on my house stairs. To show you my work, I recorded a quick video demonstrating my use of Luos, led_strips, and load sensors.Video: https://www.youtube.com/watch?v=MT_hdq4ZtUkIf you have any question, ask me (Nico1209) on Discord: https://discord.gg/BUcV9Wys3pSource code, and hardware available here: https://github.com/nicolas-rabault/home_stairs

Will it be possible one day to have as much agility in hardware as in software?

I've seen many projects (from start-ups or big companies) that couldn't scale up their embedded system because of a lack of agility. An update of the robot already sent to the factory, a lack of components (breakage) and bingo!… A cascade of problems.When you have an idea for an application, software, or a web application, you don't even think about what hardware is running behind it. It is...

Fascinating, I will finally be able to work on my Italian
Founder here, Luos is an embedded microservices orchestrator for developing and scaling edge and embedded distributed systems. Luos is built in C. Luos can connect different MCUs together and give you access to multiple features created by developers for developers (remote control, bootloader, routing table, timestamp etc…)

I got the idea to develop Luos by seeing the lack of agility we have in the embedded world as developers.

I am convinced that we can use philosophies like microservices to be as agile as software. To meet the needs of different developers, I chose to make the technology free and open-source so that everyone can adapt it as they wish.
