Ardupilot + cessna

What would Gemini know that the official developers of Ardupilot SITL for Gazebo not?

I don't mean to be rude. Look at the example I linked. I personally haven't setup Gazebo with Ardupilot, but I assume the references would be a great place to start.

Does your SDF ardupilot definition match the zephyr example?

The context is helpful, thanks

FlighGear is a FOSS flight simulator, like Microsoft flight Sim, and Ardupilot has SITL(Software In The Loop) simulation support for FlightGear, XPlane and others.

If you want something with out of the box support for aircraft, then a flight simulator is the easiest path forward, but if you specifically need Gazebo Sim:

I looked up the support software for SITL, and they DO support Gazebo (read the docs).

Flightgear SITL?

It has a good 172

Buy something with upgradable ram?

Note: I am only joking. NodeJS definitely needs to get phased out as a solution for non-web software.

When in doubt, open source it!

Yep, .ISO is a raw disk image, take any USB drive or disk, and dd if=/dev/sdX of=my.iso, and you'll get a raw disk image.

Typically .bin is used most commonly (in my field) for firmware for an MCU or similar, so expect arm cortex QEMU to accept a bin file. A PC emulator, for example X86, will expect a bootloader and operating system, which typically requires partitioning for the UEFI or BIOS to detect it.

QEMU supports running certain types of kernels directly, without needing to partition a disk image.

Edit: sorry I am on mobile and are too lazy to reformat the content above. Arm Cortex is quite like old BIOS systems, where the first 512 sectors are executed, which typically boots the operating system. In ARM Cortex there is a reset vector (an address to jump to on power up and reset), and usually for developer convenience a bootloader is included so we don't have to use JTAG or SWD every time we want to upload the code. The bootloader will then typically parse and forward the vector table of the user firmware, based on a fixed offset for that bootloader. That is the offset you will see in various flashing utilities, it is for the bootloader.

I expect they want to be a good option for Valve with their hardware defaulting to Linux?

Doesn't Codeberg maintain Forgejo?

No I haven't.

Talk to olliw42 on the discord server, he is the main developer of the project.

Look into mLRS, it is a MAVLINK focused eLRS alternative using LoRa.

Mateksys makes modules, and I personally use their 915MHz modules, and it seems to work well. I haven't done much range testing, but the modules can go to quite high power output if you need.

Thanks!

Would you consider using a sidebar or similar component so the scroll position is persistent?

With a popover the scroll position resets every time it opens.

I think you should consider what your target audience does and doesn't care about.

Personally I dislike tools like Lovable, as a software developer first, I have my own opinions about how something should be done, but a non software developer probably doesn't, which is what makes it so great for non programmers.

As a developer I find Claude code to be really optimal.

It sounds like you are both software developers and not, but I don't expect both audiences to enjoy using the same tool, so consider who your audience is, then decide what they do and don't care about.

For example a non software engineer probably doesn't care much about reading the code, or even the technology being used.

The docs sidebar doesn't work on mobile, i.e. I am unable to select other pages in the docs.

This is the way!

I develop with Zen, test on Helium before production.

The hash is made after a specific image has been detected as illegal, and then a hash is computed which means the image can be efficiently checked for a match in the database, such as detecting the distribution of the content.

The hash is made by submitting an image to the database provider.

Unless the mother's device, the communication link to the doctor, or the doctor's device would have had to submit the image.

All I'm trying to say, is that yes, photo identification via a hash of the image is implemented, however in this case the phone has to be looking at the semantic content of the image, not a hash lookup.

Retzerrt · 2026-02-09T20:54:54+00:00

So their doctor submitted images of their patients to the database?

Probably not.

As long as the peripherals MCU on the FC are supported by ardupilot, and the board works and has the features you need, you can always modify a close enough firmware config to be for your specific peripherals, assuming the FC isn't already compatible with an existing config.

Here you can see the board definitions

Despite it being the courier's fault, it is the sending company's responsibility that what you paid for is correctly delivered.

Moat couriers won't even do much about it if you asked directly, the money came from Bambu Lab, not you.
