<p>I really like epaper displays for all of the reasons mentioned in the article. Shame the patent locks continue to keep prices high even though the core technology has improved enough for prices to drop.<p>A few years ago I came into a couple of e-ink displays that had been previously used for storefront/product pricing. The hardware to drive them was locked down but I was able to reverse engineer the panel by finding a datasheet that was close enough and hacking up an adafruit thinkink. I had a lot of fun writing my own driver/abstraction layer. I originally intended to support a bunch of different panels but ran out of steam after the first one did exactly what I wanted.<p><a href="https://github.com/jaygreco/MagInkCal" rel="nofollow">https://github.com/jaygreco/MagInkCal</a></p>

<p>Ah yes, one of my favorite skills learned in school was how to work around arbitrary rules made up by cranky sysadmins! I still use it all the time.<p>The smart kids (whom I’m sure look like they are learning that precious openssh client) are doing their assignment locally or on a free tier VPS with VS Code and scping the thing over when it’s done.<p>They’re also smart enough to learn openssh when they need it IRL.</p>

<p>I came here to say this. I haven’t worked with the Elite X but the past gen stuff I’ve used (865 mostly) the accelerators - compute DSP and much smaller NPU - required _very_ specific setup, compilation with a bespoke toolchain, and communication via RPC to name a few.<p>I would hope the NPU on Elite X is easier to get to considering the whole copilot+ thing, but I bring this up mainly to make the point that I doubt it’s just as easy as “run general purpose model, expect it to magically teleport onto the NPU”.</p>

<p>I don’t know the size or structure of your team, but one thing that has worked for me in addition to other strategies mentioned on this thread (specifically, that oncall is oncall, nothing else) is that you appoint one engineer - typically someone who has a more strategic mindset as the “OE Czar”. They are NOT on call, and ideally not even in the rotation, but rather there for two reasons: to support oncalls when they need longer term support, like burning down a longer running task/investigation or keeping continuity between shifts. The other is identifying and planning (or executing on) processes and systems for fixing issues that continually crop up. Our mandate was 20% of this person’s time spent doing Czar tasks vs scheduled work.</p>

<p>I spent quite a bit of time a few years ago recovering my old MySpace account only to realize they “messed up” (unclear whether it was incompetence, or purposeful) and deleted basically anything that had been, oh I dunno, actually interesting: pictures, videos, playlists…you can’t even see the profile pictures of people in your friends list.<p>In the rush to move to whatever the next big social media was, I’d never thought about backing up my stuff because why would it ever be gone and why would I care? Lesson learned.<p>I was weirdly bummed out about it. Back when the site first launched I spent loads of time learning HTML just to customize my page before I realized site profile generators existed.</p>

<p>I bought a car thing when Spotify was blowing them out, knowing full well they’d kill it. I planned on hacking on it and finding a cool alternate use for it. I have actually enjoyed using it at my desk as a dedicated “now playing” screen but the way it relies on Bluetooth drives me a bit crazy.<p>My ideal homebrew app is just like the 1p Spotify one, but with the ability to use network over usb or the like so that it doesn’t need to sync the play status via Bluetooth. I guess the imminent shutdown might actually motivate me to do something along those lines.</p>

<p>From one of the links [1] in this article:<p>> Prusak explained that one Bitcoin is equal to about $35,000 in U.S. dollars, adding that he doesn't have a specific number on how many Bitcoins the site is able to produce in a day.<p>> "There's a lot of math, so I can't say we make 10 a day or anything like that," he explained. "I can say that they're worth about $34,000-$35,000, and we've got, you know, tens of thousands of machines running to do that."<p>This really rubs me the wrong way because it’s patently untrue. It’s _very_ possible and in fact is quite easy to calculate the expected daily returns. Prusak might be dull, but I’d lean more toward deceptive. He just doesn’t want the locals to know how much he’s profiting at the expense of their comfort.<p>[1] <a href="https://www.hcnews.com/stories/granbury-us-bitcoin-corp-erects-24-foot-soundproofing-wall,21717" rel="nofollow">https://www.hcnews.com/stories/granbury-us-bitcoin-corp-erec...</a></p>

<p>This is awesome and timely!<p>I’ve been wanting to set something like this up for the nullbits server for a while. When I picked discord instead of a forum, I wasn’t counting on the growth we saw. There’s a lot of friction for new folks who aren’t yet on discord, and there’s a lot of knowledge in the server that’s locked behind discord.<p>Just set everything up! My only feedback is that enabling indexing for all of our text channels took a while doing them all individually, but that’s kind of on me for not enabling forums for help requests until now.</p>
