Given their history, I would guess <$6 a piece for a dev board, <$2 for the chip at scale.

Arduino nano are made by arduino using Espressif chips, and Arduino IDE support is indeed hit and miss.

ESP-IDF, the official C SDK, is a bit more work, and there is drama around platform-io, but it’s significantly more stable.

> there is drama around platform-io

What do you mean ?

Boards like the ESP32-C6, almost 5 years old, are not supported in PlatformIO with Arduino libraries, because they refuse to update the Arduino core in some kind of stand-off with Espressif. This has been going on for years. There is a fork [1] that offers support but none of it makes back upstream.

As a hobbyist I've given up on PIO and moved to a barebones arduino-cli setup instead. Much lighter and less painful.

I hope this one has multiple radios so you can actually use BT/Wifi/Thread simultaneously.

Power?

RISC-V is also open. That “some reason” is likely to be power/performance levels being quite far from ARM & Intel for consumer devices.

China is building out RISC-V, just like they are leading actually-open AI.

Weirdly, the authoritarian state is the one saving us from our own digital authoritarians.

> they are leading actually-open AI.

How are they leading? If I parse this correctly, "actually" open would mean fully open data training and weights? Then, by this definition, I'm only aware of Olmo (AllenAI - Seattle), Apertus (Swiss) and to some degree (unclear what data was actually published) Nemotron (Nvda, US). What are some examples of chinese similar models? (I'm not aware of any).

RISC-V is slow though

RISC-V is an ISA.

There's nothing inherently slow about it, anymore than there is anything inherently slow about x86 or ARM.

High performance microarchitecture implementations are definitely possible. Some of them are available for licensing.

At least one of them (Tenstorrent Ascalon) has been tapped out into a chip and will show up in development boards later this year.

Releases are signed, but lockfiles are not commonly used for this purpose. For your home env you'll usually want the latest version of every tool.

When installing tools, or via mise.toml, you can define version ranges with the precision you'd like - "3" / "3.1" / "3.1.2".

A thought: is the ejected space poop going to continue to travel in space at 15000km/h and eventually drop into the sun, or will it also be captured by gravity and land on the moon?

Delta-v relative to the Orion is probably not that big, so I guess the waste will also circle the Moon and follow the crew into Earth's atmosphere.

Urine is ejected, solids are collected and returned to earth.

I don’t know if this craft has it, but they’ve been announcing all over that we’ll get 4K over a 260mbps link from the moon, so that shouldn’t be a problem

Hopefully they are not getting exquisitely crafted newsletters in space.

Clout and reaching the top of HN apparently.

The animated explanation at the top is also way too fast at 1x, almost impossible to follow; that immediately hinted at the author not fully reading/experiencing the result before publishing this.

Claude itself can generate this in minutes if you know how to ask.
