ARM boards need a custom kernel and bootloader. These aren't things managed by the distro. The userspace IS managed by the distro and IS standard. Using yocto to manage userspace maybe made sense 15 years ago, but it has long since become far more trouble than its worth. Debian supports most architectures out of the box, has good cross-building infrastructure, many thousands of ready-to-use packages, and is non-weird.

Modern SBCs are just normal computers and not "embedded" in the traditional sense. You can generally just use Debian, and spend time on the actual project, instead of wrestling with the system

At least with android devices, you can plug in any usb keyboard, and have it work. Those are free, in the garbage all over the place

A dedicated key for all window-manager things is what people that have thought about it do (I use the "windows" key). But keyboard manufacturers haven't thought about it, so sometimes reasonable things aren't possible. I don't know.

It sorta looks like they're trying to reinvent Debian, and kinda failing?

Debian has their own nvidia driver packages (it's nvidia's drivers repackaged in a nice way that integrates with the system well). I can't say if they're "outdated" or how different they are from what ubuntu ships, but they've always worked very well for me.

Debian is great, and is where the distro development actually happens. What doesn't it do that you want?

GNU Make has a debugger. This alone makes it far superior to every other build tool I've ever seen. The cmake debugging experience is "run a google search, and try random stuff recommended by other people that also have no idea how the thing works". This shouldn't be acceptable.

I'm suggesting that people creating build systems read the make manual. Surely this isn't controversial?

If you think cmake isn't very good, the solution isn't to add more layers of crap around cmake, but to replace it. Cmake itself exists because a lot of humans haven't bothered to read the gnu make manual, and added more cruft to manage this. Please don't add to this problem. It's a disease

I use vnlog and feedgnuplot to massage and plot data on the console all the time. It's even less than a tui, but might be what you want.

New comment by dima55 in "Show HN: Lensboy – Lightweight camera calibration with spline distortion models"

dima55 — Mon, 02 Mar 2026 19:57:37 +0000

Hello! I'd love it if this and mrcal could work together. Do you support mrcal .cameramodel files? If not, can you do that? Is your splined representation compatible with the mrcal splined stereographic model? If not, can it? Is your splined lens representation better in some way? If so, should mrcal use some of that logic? I didn't see any documentation about it. If you think the mrcal distribution methods could be improved, and are willing to help improve it, I would be very amenable. Let's collaborate to make both projects better!

dima55 — Tue, 24 Feb 2026 21:49:26 +0000

I would love for us to move past the idea that non-pinhole projections have "distortion", and we should strive to remove this "distortion" by reprojecting stuff to pinhole models. In practice, ALL projections distort straight lines and/or shapes and/or sizes, so if you use the pinhole projection everywhere, your images look like crap (see iphone wide-lens camera output for instance). Most of the normal non-pinhole projection functions work fine for wide lenses, while behaving like a pinhole lens with long lenses: https://en.wikipedia.org/wiki/Fisheye_lens#Mapping_function

This is real clunky from a browser. https://caltopo.com can do this from a map (right-click on the viewpoint, point-info, simulated view). The horizonator (https://github.com/dkogan/horizonator/) is a hackable implementation; has a FAST local gui, and can easily be extended to do other stuff.
