GPS lost signal suddenly and recover
Op, it seems your gps has m10 chipset, am I right? Because the m10 is not supported on betaflight. Or rather, it works, but betaflight sets it up incorrectly. There is a fix, but not released yet, or you have to set gps to 10hz in ucenter and disable auto convig in betaflight (and lose some features). See https://github.com/betaflight/betaflight/issues/12737 for more information. This might not be your issue, but it might be related.

Need help flashing 5 year old quad
I got older betaflight configurator 10.3.1 and when I look at boards in firmware flasher there's a small selection of boards and OMNIBUS is missing. So I've downloaded .hex file from here https://github.com/betaflight/betaflight/releases/tag/4.0.0 for 4.0.0 and tried to flash it from local file but nothing happens in betaflight and the quad has a constant beep sound. When I disconnect it from usb and reconnect it still works fine but its on old 3.1.0 version. I'm not sure what to do here.

Betaflight GPS 4.4 issues
It’s a known issue specific with the M10. I think there a workaround if you need it asap. https://github.com/betaflight/betaflight/issues/12737

I was testing the failsafe so why did the drone start falling like this? *I've recovered it now*

Is speedybee f405 v3 reliable? Or should i get mamba f722 app
Blackbox logging doesn’t work reliably since the Blackbox and OSD use the same SPI bus (https://github.com/betaflight/betaflight/issues/12583)

Switch pid profiles
You can select between PID profiles 1, 2, or 3 via the OSD or stick commands fairly easily, and there are options to modify the individual P, I, and D terms per axis in flight using AUX channels via the adjustments tab. If you want the option to configure a 3-posiiton switch to select between PID profiles like you currently can with rate profiles, maybe bump the thread for the BF devs here.

Newbie flashed Betaflight on DarwinFPV TinyApe and now Gyro and Accel are gone!
I looked on GitHub for a similiar Issue with Darwin AiOs just now and found this from January 6th concercing 4.4 Update Errors with Accel/Gyro: https://github.com/betaflight/betaflight/issues/12145

NumWorks: An open-source graphing calculator (with Python and Rust support)
I've engaged in debates on HN about the definition of "open source" in the past, so there might be some disagreement about the meaning of the title.
I've settled on using "OSI open source" to avoid this, since those discussions are uniformly tiring and unproductive.
That said, I agree with parent: the repo specifically has a section regarding copyright and it simply says that all rights are reserved[0]. This is proprietary software, disallowing copying, distribution, and derivative works. It's weird, since even cloning the repo appears to be a violation of their stated terms, though they supply instructions for building the software yourself that of course requires copying the code to your machine first[1].
Copyright is weird.

Phi – Jailbreak for new locked-down Numworks calculators
They still are open source [1].
If I had to guess, the reason they locked the bootloader is the same reason they removed the symbolic math functionality (which is re-added in Omega [2]), test accreditation.
They want to create a calculator to provide a good and viable alternative to TI. They can only do that if their calculator is allowed on tests like the ACT, SAT, etc.

Epsilon on raspberry pi?
Yes, you can compile it yourself from source, but the Python app isn't very stable since some file is only adapted to x86-64 and not ARM. E.g. mandelbrot(20) crashes directly. https://github.com/numworks/epsilon/issues/1642

Port Epsilon to another microcontroller?
Yes : https://github.com/numworks/epsilon/pull/534

Characters found using ordinary print() and chr() from module builtins - same as in kandinsky
Jokes aside, the epsilon firmware that's powering the NumWorks calculators is Unicode-capable. Specifically, https://github.com/numworks/epsilon/blob/master/kandinsky/fonts/code_points.h is the list of codepoints supported by the firmware. Some of them have special purposes, for example codepoints around 0x300-0x36F are combining diacritical marks meant to be combined with other codepoints.

NumWorks – An open source Graphing Calculator
That is beautiful. I wish the company great success.
> Epsilon is a high-performance graphing calculator operating system.
> It includes eight apps that cover the high school mathematics curriculum.
https://www.numworks.com/resources/engineering/software/
https://github.com/numworks/epsilon
Looks like this single codebase is used to build for the calculator device, and all targets for the simulator: Android, iOS, macOS, Windows, and the web.

Midterms
Indeed, for the equation graph, it should be possible in v17 according to https://github.com/numworks/epsilon/issues/1787

Graph a circle
You can't plot implicit graph yet, but that's in numworks mind (see the link). Currently, the only solution you have is to convert it to parametric, and change the setting of the function.
