While it is a ‘they’ it never will get better.
‘They’ are mainly interested in ‘them’. If it happens to benefit someone else, then that is a happy accident.

Social Media was meant to be the great leveler - letting the voice of the people be heard.
Well, we heard it and it turns out to be pictures of their cats!

So, that's my queue to break in with the shameless self promotion—or rather, a meetup topic: open source.

How altruistic is a lot of open source tech these days? For example, Zephyr started as a commercial RTOS built by a company that was acquired by Wind River and then open-sourced under the name Rocket and then pushed to LF—but you better believe WR is interested in converting commercial Zephyr users to VxWorks or WR Linux.

Who are the progenitors and maintainers of Zephyr and other popular open-source technologies? Does it matter?

I'd like for this to be the topic of this week's OH meetup but would also like to hear the community's thoughts here.

At best, an open source technology is something that mainly benefitted someone and in some cases gained popularity through the happy accident of also benefitting others. Then marketers realized the power of the messaging and have spun up a largely rosy image of homebrew + counter-culture + cost savings + flexibility + self-reliance that it's hard not to get on board with.

You're missing something here

Things taking less time should lead to more free time and frolicking

You're actually mad that the structure of society is such that everyone needs a job, i.e. at money and capitalism

To me it is crazy to think we would keep "busy work" for the sake of it, so we can give people made up tokens..... maybe you need to take a step back to see it, but this is very crazy

ke7c2mi•10/16/24, 12:40 PM

To try and express this in a more concrete way, lets say for the sake of argument, it takes 100 hours of human labour to provide for 1000 people

We can see the % utilisation per person is 10% to maintain this. Lets say the rest of the utilisation is made up with frolicking. Society is 10% work, 90% frolick

Lets say we have an innovation, and now it only costs 50 hours to provide for 1000 people, now the % utilisation per person is 5%, and we are at 95% frolick

In your statement you claim that %frolick goes down as %utilisation goes down, but we can see that the natural effect in this system is that frolicking goes up with utilisation going down

So - go and find the mechanism that makes what you said true (and it IS true today) - and get very specifically mad at that bit

When I connect the Arduino uno R4 wifi to the computer, the connected COM does not appear, knowing that I connected the ESP32 and the Arduino uno and they work without a problem. What is the solution in the Arduino uno R4 wifi?

Michael W•10/18/24, 1:07 AM

I'm a system administrator/engineer, mainly dealing with computer networks. I'm a hobbiest and attempt to teach myself new things all the time. I've done some arduino programming and a bit of a gear head. I've developed a digital dashboard using a RK3399 from Firefly for a car that I'm doing a retro mod on. I've gotten to a point where I feel my next step in doing what I'm wanting to do with it will require me to make my own PCB's because the things I'm wanting don't exist. I would say I'm a novice to intermediate with PCB components, where I understand what things are and can look at schematics or wiring diagrams and understand them.

ZacckOsiemo•10/18/24, 5:51 AM

yeah this is cool but this is also a bit obviously skewed, I am wondering about demoing like specific features say we have a mutex problem and we try to solve it with FreeRTOS and Zephyr but on the same architecture

ZacckOsiemo•10/18/24, 5:53 AM

Say something like 2 tasks wants to share 2 uart to communiicate with a terminal, we could implement this on stm32f4 on zephyr and same on stm32f4 on freertos, then step back and look at the differences between both approaches, would you be keen on that @melta101

ZacckOsiemo•10/18/24, 5:53 AM

It's like when we used to do the same app on react, elm, vue, angular then benchmark.

Excited to hear from @Middleware & OS devs in particular to come share your experiences with open source technology, and perhaps lend some tips to your fellow devs so they can avoid any OSS pitfalls in their development.

Oh there should be plenty to help out with this, DINO, but @Umesh Lokhande would probably have a good idea of where to start or some sessions we may be able to put together around the topic since he's built training sessions on Pi before.

Otherwise @wafa_ath and @Renuel Roberts have Pis.

Here's a playlist to learn bare-metal programming of RPi https://www.youtube.com/playlist?list=PLVxiWMqQvhg9FCteL7I0aohj1_YiUx1x8. Personally, I'd prefer PICO over RPi3/4/5 to learn bare-metal. If you're a little bit experienced then maybe it's fine to choose regular RPi.
