We use Zulip (https://zulip.org/) for our corporate chat, and we've never looked back. It's been good, and it's fully open source. We self-host, but paid hosting is easy to get too if you want.
Wow. This project was the cause of a very long and intense discussion about mis-use of the term "open source". See https://github.com/n8n-io/n8n/issues/40#issuecomment-5397146... for details (lands mid-thread -- you might want to scroll back to see the start, and if you read the whole thing to the end then you deserve some sort of award!).
TL;DR: The author originally tried to call n8n "open source" but while using a non-open-source license. After much discussion, he kept the license but stopped using the label "open source", to the relief of many people.
That half-decade-old thread is still what I point to when I want to explain to someone why preserving the specificity of the term "open source" matters.
Most of the comments so far are about the temperature and the closeness to the sun, and, hey, I get it: those are both amazing to think about. But to me even more amazing is... 0.16% of the speed of light?? Yikes.
That part about "...you wouldn’t want to wing it with the configuration, because allegedly you could break your monitor with a bad Monitor setting" -- strike the "allegedly"! Or at least, let me allege it from personal experience: I did that to one monitor, in the early 1990s. You could smell the fried electronics from across the room.
AHHHH, that's the key thing I didn't know (I have a Raspberry Pi sitting in a drawer and have played with it embarrassingly little -- I didn't realize how important having the SPI or other special interface is in this context). Thank you again.
Thank you. My idea was more the opposite: do it with a normal laptop or desktop computer driving the display, rather than a tiny microcontroller. I guess I'm assuming that either the display's USB input supplies enough voltage to run the display, or that the display has a separate power supply -- i.e., that there's nothing magical about a Raspberry Pi that makes it supply special bits or special voltages to these displays that can't be supplied by, say, my desktop computer.
Does anyone know why projects like this always seem to specify using a particular type of tiny, low-power computer (usually a Raspberry Pi or something similar) to drive the display?
I already have plenty of non-tiny computers that run Debian GNU/Linux. Suppose I wanted to run an e-paper display from one of those computers, using this code, just via a normal USB cable. I could do that, right? There's no reason I would have to use a Raspberry Pi or something similar?
The most important factor in my learning Emacs was doing it in a room with experienced Emacs users. I really strongly recommend doing this if you possibly can. A few minutes of an experienced user shoulder-surfing while I worked, and giving advice on better ways to do things, was worth hours of self-directed study.
Get together with experienced users in person and have them watch you edit. That's it.
There are algorithms where I think "Sure, with enough time and attention given to the problem, I might have thought of that." And then there are algorithms where I think "Oh, wow. That came from another planet. I would never have come up with that myself."
Very happy user of a System76 Lemur Pro laptop (i7, 32 GB RAM, 1 TB SSD) for the past year, FWIW. I'm running stock Debian on it, not System76's Pop!_OS.
I get the kind of battery life the review mentions if I put the laptop into "Power Saver" mode. In "Balanced" or especially in "Performance" mode the battery doesn't last as long, of course. So when I can't be plugged in, I put it into Power Saver mode (this is super easy via the Gnome upper-right settings popup panel; I assume it would be just as easy in other window managers).
I got great customer service from System76 when I ran into a hitch at the start of my Debian installation process (TL;DR: see Debian bugs #1024346 and #1024720 -- the file ".disk/info" existed on the pre-installed Pop!_OS partition; getting rid of that enabled the installation to continue). System76 support went above and beyond the call of duty in tracking this down and solving it, considering that I was installing an OS that wasn't even officially supported by them.
Happy customer; would buy again; I get no commission for any of this -- I just want to see the company flourish so they're still there when it's time for me to upgrade my laptop!
The linked page is on signalusers.org, but Signal's regular home site is https://signal.org/.
I'm looking all over signal.org for some link from there to signalusers.org, as that would make me more relaxed about the authenticity of the latter -- i.e., that it really is run by the same people who run signal.org.
Yes, maybe I'm being paranoid. But we're talking about an app whose whole purpose is secure communications :-).

Just following up to say thank you, @Daeraxa and @jjgreen, for the examples.
@mdwalters, good luck with the text editor, and @wmf we may not personally agree on the AGPL but we do agree on the usefulness of the OSI doing this research!
Not mixed feelings here: I wish they wouldn't do that. No doubt it was meant as respectful homage, but the effect is to flatten and obscure his particular qualities, because they have no specific connection to this product.
