The AS7343 Spectral Sensor measures 13 channels of light from (~380nm to 1000nm) as well flicker detection all from a single IC.

By well-known mathematical physicist John C. Baez. This refutes the article that floated around a few days ago saying the universe would end sooner than expected. That article was based on the premise that dead stars (big chunks of matter that aren't black holes) emit Hawking radiation the way that black holes do, and that the matter in the universe would eventually decay through this mechanism. The linked blog post says that the premised is wrong, and matter in normal space doesn't give off Hawking radiation. I guess in 10^74^ years (iirc) we will find out who was right!

He has passed at age 88, cause not specified.

Not sure if I'm posting to the right place since I think this is a lemmy.ml federation problem. I was subscribed to c/[email protected] but hexbear renamed itself to chapo.chat, so updates are now going to c/[email protected]. I try to subscribe to that from lemmy.ml and it says "community not found". I can view it directly on chapo.chat and while it's low activity, there is at least 1 newer post there than on .ml's feed of hexbear. Help?

Costs $90, physically looks just like 400 (no pointing device), has 8gb ram and includes a 32gb microsd card. CPU is similar to Raspberry Pi 5. There is a desktop kit for $120. So it's a $20 increase over the Pi 400, but you get an extra 4gb of ram, and an SD card. There is also a 15.6" HDMI monitor available for $100 that draws power from the computer. It's not clear to me if there is an NVMe SSD slot in the computer. It's disappointing that there is still no pointing device.

They have also decreased the 400's price from $70 to $60, and the 400 desktop kit (400+16gb sd card+power cube+mouse) from $100 to $80. I have a 400 and it is nice, but of course the 500 is a significant upgrade

Added: from this comment, "Jeff geerling just did a teardown (on his “level 2 jeff) channel and it seems there is provision on the board for a M.2 slot, but the slot and it’s support components are not populated. He actually soldered down a M.2 connector but then realised that it wasn’t just the slot that needed populating." What a pain. There are other comments speculating on a future model with a slot.

Because of the lack of M2 slot and pointing device, I'd have to carefully weigh getting a Pi 5 and external keyboard instead of a 500.

I wasn't able to find one by poking around but may have missed it. Tx.

There is a thread in another community regarding some controversies happening in women's chess. I posted to that thread, recommending a book written by WGM Jennifer Shahade who is a multi-time US women's chess champion. I also linked to a review of the book, the url of which contained the book title.

The Open Library page about the book is here: https://openlibrary.org/works/OL5849601W

it seems that the title, as chosen by the female author with considerable self-awareness, contains a word that is sometimes used as a sexist slur. You can see the title by clicking the link above. Unfortunately some kind of bot censored the title from both the post, and the review link (to chessbase.com) that I had posted. I was able to fool the bot by changing a few characters, but the bot's very existence is imho in poor taste.

We are adults here, we shouldn't have robots filtering our language. If we act sexist or abusive then humans should intervene, but not bots. Otherwise we are in an annoying semi-dystopia. The particular post I made, as far as I can tell, is completely legitimate.

Despite lemmy.world's current travails, its flashlight community is fairly active, while the lemmy.ml one has been dead for 2 years it looks like.

Down with the algorithm telling us what to read. I just want to see most recent first. Thanks.

https://lemmy.ml/c/[email protected] got that error a few minutes ago when lemmy.world was having some db probs, but works now. I had thought federated posts were supposed to be copied to the local server, and anyway a raw 502 is a confusing diagnostic. This is basically a bug report.
