Porting complex applications (especially those written in C) from x86 to ARM can be pretty non-trivial. I can't speak to the GIMP code in particular, but I've done several x86->ARM source ports of other complex software, and ea

We live in an age where combining music, software, and signal processing can let you do some amazing things. I can imagine a high-fidelity simulation of this instrument's timbre before it's ever built, by using the mechanical CAD

There is no way this could work. The EDA tool (e.g. KiCAD) is only the first step of the fabrication process - you generate Gerbers from your KiCAD board layout, which are a highly standardized format that can be viewed in a variety of inde

A big shoutout to Alyssa here. For those of you who don't know, she is doing this work as a college student .

This is getting at the idea behind the Fourier transform. 3b1b did an excellent video with exactly this visualization: https://www.youtube.com/watch?v=spUNpyF58BY The idea is that wrapping a function around a circle at the

The AGPTek Rocker is one of our last targets still in production and can be acquired for around $50. I haven't used one myself, but from what I hear it's fairly decent but not perfect.

This reminds me of my port of Quake 1 to Rockbox (for MP3 players): https://news.ycombinator.com/item?id=22162834

That's correct. I realize my parent comment was ambiguous. I'm the author of the port; the video is by a different developer who's since taken it down.

I'll add in another fun anecdote while I'm at it. There are virtually no good ways to debug code on-device with Rockbox, short of adding in a bunch of function calls to print variable values to the device's screen. This usual

Thanks! Resolving that bug took quite a bit of serendipity. The break came when I was on the verge of giving up on the assembly rewrite and reverting back to C. I'd left my "frozen" iPod sitting around for a while. ~15 minute

(Author of linked post.) That video was recorded by another developer, who had some personal (non-legal) concerns with it and plans to reshoot.

Author here. This is actually a fairly old project of mine by now, but I just recently submitted it to Hackaday, which is probably why it's surfaced here. The original video demo has been taken down by the author (not me) due to some c

Good idea! I'm not sure that's easily achievable with my current architecture, though.

+1 for the nit-pick. Hardware programming make me think of FPGA design and Verilog, etc. I'd call this 'embedded programming'.

Excellent work! Clean C is underrated nowadays.

I learned C and open-source through hacking on this. Fond memories! PS: We have a Quake port - https://www.rockbox.org/wiki/PluginQuake :)

A charged particle moving at an angle to a magnetic field like that found at the ends of a solenoid (increasing field strength) would produce the desired motion. Example: https://s3-us-west-2.amazonaws.com/courses-images&#x2

I don't see why this is getting downvoted. It's a perfectly valid argument that's very much in the spirit of 3b1b.

It's just a conversion factor to make the units come out nicely. He could have easily done T = 1/f to give the refresh interval in seconds, but with such a short duration, it helps to convert it to nanoseconds (1e9 ns = 1 s).

Quick question: how does the electricity get from the train (in motion) to the grid? Using the rails as conductors could work, but I'm not sure how efficient that would be.
