@whitequark So cool to see JTAG boundary scan being used outside of expensive in-circuit testers and the like!

@hennichodernich @whitequark I'm a bit stumped that I can't find the DAC/ADC sample rate prominently listed in the datasheet.

@esden @whitequark

FWIW, Horizon EDA handles this by making symbols expandable in width to accommodate longer pin names resulting from alternate functions: https://blog.horizon-eda.org/progress/2021/01/28/progress-2021-01.html#symbol-expand-preview

This one is for all the trans folks that keep our networks running: Happy trans day of visibility! :trans_flag:

Ever wanted to hug an Eurobalise?

Now you can, with the (first ever?) stuffed toy Eurobalise!

Thanks to @leona for giving me the idea in https://chaos.social/@leona/110604500758468533

Since everyone here seems to love cursed technology, I made a chart rating various interfaces by their perceived cursedness.

Some like 10G BASE-T have a reason for being cursed, whereas others like USB PD not so much.

Any additions?

@LaF0rge That's precisely why I made this poll. In the colloquial sense, Downloads means "to my computer", but the USB DFU spec somehow seems to describe this from the device's perspective. So when someone refers to firmware download, I'm always confused if they're meaning it in the DFU or browser way.

After implementing arcs in 2 (two) CAD applications and bezier curves in one, I can conclude that bezier curves are the superior way to represent curved lines.

- No worries about the direction an arc goes
- Not having to deal with normals in 3D
- Linear transforms 'just work'

As you may have guessed, Dune 3D now supports bezier curves 🎉

Apart from that, we now have DXF import as well.

So you're developing a cross-platform library that deals with filenames as a const char * (or the equivalent thereof)? On Windows, please treat the the filenames as UTF-8 and internally convert them to UTF-16 to call the Unicode Windows APIs or only have a wchar_t* function available.

DO NOT pass the filename as-is to the ANSI Windows APIs. With char * being treated as UTF-8 encoded text, this appears to work until an umlaut or another non-ASCII character appears in a filename.

Thank you.

So your software needs a list of screen resolutions? Here's how to make it look nice:

1. Instead of an 'x' use '×' U+00D7 MULTIPLICATION SIGN
2. Use tabular figures
3. Left-pad the width with U+2007 FIGURE SPACE

That way, all of the the × line up nicely in the same column.

So… I'm writing another piece of CAD software 🤓

Say hi to Dune 3D, a parametric 3D CAD that supports STEP import, chamfers and fillets!

It's the result of gluing together the UI from Horizon EDA with the solver from solvespace and Open CASCADE for a geometry kernel.

After about 3 months of off-and-on development, it's finally ready for prime time, go check it out on https://github.com/dune3d/dune3d#readme

Don't be surprised if it's a bit janky or lacks some features, there's still a lot left to be done…

Dune 3D is coming along nicely :) Thanks to everyone brave enough to give alpha-quality software a try!

Apart from fixing a lot of bugs, UI jank and implementing some obviously missing features, we now have a rough list of features for version 1.0: https://github.com/dune3d/dune3d/issues/19

The camera in Dune 3D now uses quaternions:
✅ Less lines of code
✅ One can look at the model from all angles
🤷 I still don't quite understand quaternions

OH: Ein RGBlahaj

Why did they call it the Nintendo eShop and not Nintendo .DS_Store?
