Toradex Luna uses the Synaptics sl1680, which has a unique way of formatting the eMMC for boot. In this blog post, I will show the PhobOS unified flash image for flashing the eMMC on the Toradex Luna. From Yocto 16 .subimg files to just 1 raw disk image: microhobby.com.br/blog/toradex...

AI is doing another annoying thing to software developers besides "AI will take your job." Anything you show, even if it took a lot of work, no matter how difficult it is, there's that idiot who says, "oh, but with Claude that was easy" 🙄

It's Debian, it's secure, it's atomic, it's OSTree, you can still apt-get install without the need for containers and use torizon.io update system. It's PhobOS!

Ever wondered if you can run Windows CE on a Raspberry Pi 5? Probably no 😅. But it was fun and I learned a lot of things trying it. In my last video, I show Windows CE 7 running on Raspberry Pi 5, even blinking LEDs 🤯. Check it out: youtu.be/do2CChP5tK8 Blog post: microhobby.com.br/blog/2025/02...

Finally I had the opportunity to have Windows on arm in my hands. Sneak peak of the first build to Torizon OS Development Env for WSL 2 arm64 🤩. arm all the things, on your development board, on your product and on your development PC.

I have to be fair. After some days using a Mac Mini M4 I have to say I'm impressed. Everything runs smoother than on my Windows 12th generation Asus i7. And the system is beautiful 😍. I'm still having hard time with shortcuts, but with Karabiner I can remap some I was used to from Windows.

Now I'm a Python developer and I have a Mac. ohh f*%$, I've become what I feared the most 😱

I failed to show my coworkers the best of the .NET. And I was influenced to follow with Python. It's bigger, more popular, and new (not new, but young people love it). I would have more acceptance and increased chances of contributions. Bye .NET, it was a good ride 🥲

The EU should demand that American Big Tech sell their assets to European companies. They can’t be trusted to not manipulate the data for propaganda reasons. Not doing so is a national security risk. Am I doing this right?

If you are looking for a permissive json library for python, you can try json5. >>> import json5 >>> json5.loads("{ arch: 'arm64', torizon_arch: 'aarch64' }") {'arch': 'arm64', 'torizon_arch': 'aarch64'} but remember you are not doing json!

It appears that the following string is not valid JSON for Python 🤦 "{ arch: 'arm64', torizon_arch: 'aarch64' }" json.decoder.JSONDecodeError: Expecting property name enclosed in double quotes

Tried now the "Nvidia Gerforce Now". Is PRETTY BAD! Does not have 4K support, the latency is horrible and keeps disconnecting all the time. Fortunately, I only signed up for the day pass.

Note: I'm using Python nowadays, but I'm being forced into it. Not that I like it.

Cool, very cool. JSON is built-in in Python but YAML is not. And the Python people continue to use YAML in everything that would be better off as JSON. 😏

oh boy, thanks for reminding me that I'm this old. I started developing for Android when we only had the plugin for Eclipse.

Nice, so you can't do something like this on Python: i = 0 i++
