My brother told me this story of the raccoons living in his backyard. The mother had figured out how to defeat a new supposedly raccoon-proof garbage can and lined up the cubs to demonstrate. The first two watched with rapt attention while a third had a kind of dazed look. The mother then came back and smacked him in the head before showing them again. That seems like a pretty good indication to me that she had a good grasp of the mental state of her cubs?
Oh I see. syncthing is more for keeping 2 directories synched between machines. I guess in a sense, it’s more of a Dropbox competitor while croc and sharr are for one-off file transfers. For awhile, I ran an owncloud server at work for internal use. It was pretty good for file synching, but required some port forwarding through the router. These solutions mentioned here seem to all have a public host somewhere to eliminate that need.
Cool. I’ve been using croc lately to move files around, but this differs in that they are supplying temporary off-site storage so that the host doesn’t have to remain online.
Well that’s the way it should be. If they’re selling your data, they should compensate you for that in some way. Then it becomes a personal decision as to how much it matters to you.
Ah that makes sense.
I think another thing that might be uniquely Canadian is when you’re paying at a drivethru and you see the machine emerge from the pickup window taped to the end of a hockey stick. That was a big thing during the pandemic for social distancing. I guess more recently, they’ve been moving to less improvised solutions, which is a shame. I really liked the hockey stick!
The cash I have on hand comes exclusively from playing pub gigs in a band. That is still very much a cash-driven economy where I am. When I accumulate enough, I usually wind up spending it on music gear, so I don’t think this hobby of mine is major wealth-builder. But while many businesses are moving away from cash, it seems music stores are used to people like me and still allow fairly hefty cash transactions.
The other day I was settling my tab at the pub and the guy hands me a machine. I say, I’ll pay by cash thanks. He says really?!? Dude, you literally just handed me cash for the gig tonight. Oh yeah…
Canada has universal tap to pay also, but what surprised me about the UK—at least in the London area—was how quick it was? The payment processing was near-instantaneous. In Canada, I think the machines make a phone call behind the scenes to a bank or something? There’s a significant delay before it goes through.
So you’re saying the comments themselves get cached on the local instance where the user is registered before being synced with the remote community-hosting instance?
I honestly don’t know how these things work internally, but had assumed the comments needed to go straight to the remote instance given the way you can’t comment once said instance goes down? You can still read the cached content though.
When I first heard the term “fediverse”, it immediately made me think of some sort of vast interplanetary network. And let’s face it: a fediverse-like model is really what you would need if you had settlements scattered throughout the solar system. A monolithic, centralized service would be awful, given the reality of communication lag and likely limited bandwidth.
So let’s say lemmy (or more generally activitypub) were to go interplanetary. How would that work out? You set up your first instance on Mars. Any content that’s posted there will be immediately available to your fellow Martians. Earthlings who subscribe may also be able to view it as their instances cache the content, albeit after some delay.
But the trouble starts when Earthlings want to start contributing to the discussion. If they have to wait the better part of an hour to get a single comment lodged, it’s going to get old fast.
So you would need to allow the Earth side to branch off to some extent from what’s happening on Mars. Then eventually, something like a git merge would try to bring it all back together? I wonder if that would work?

100g * 9.832m²/s
That should be 100g * 9.832m/s², or better yet 0.1kg * 9.832m/s² to get a number in newtons (N).
From a high school physics perspective, holding a 100g object steady for any length of time does no work, since work is force applied over a distance, measured in joules (J). What you do have is gravitational potential energy. Potential energy is the ability to do work, also measured in joules. Once you release the object, then you actually start getting numbers for work and power.
Power, measured in watts (W), is work done per unit time. So 10W/hr would be (10J/s)/hr. I guess that would be the rate of change of power consumption, if that were useful to you?
In theory, energy and work should be measured in joules. Simple as that. But this unit of kwh (kilowatt∙hour) has come into vogue, presumably because that’s what power utilities show on the meter outside your house? 1 kW∙hr = 1 kJ/s∙hr ∙ (1000J / kJ) * (3600s / hr) = 3.6MJ. So now we’re back from power to energy consumption.
I signed up and so far my feed seems to be dominated by a lot of bird pics. I guess that’s fitting for a site called bluesky?
My fave has gotta be kwh/yr/ft². I came across that while researching the lighting requirements for hydroponics.
Noted. Thanks!
#2 is certainly food for thought. So the idea is that from a journalistic fact-checking point of view, it is more important to convey the information exactly as it was presented than to verify its accuracy?
This would explain why science/engineering-based articles are so commonly inaccurate or missing in critical details. The journalist can fall back on saying “I have a recording of an interview with the expert after we downed a few pints at the pub, and I’m just parroting back what he said. Don’t shoot the messenger!”

2nd paragraph and he’s already lost me. It would be nice if tech columnists had the equivalent of even a single semester of high school physics.
I work with 32MHz microcontrollers at work and you can do plenty with them. It’s a different world from say general CPUs where speed is king. You’re often more concerned about timing reproducibility than outright clock rates. There are also considerations about power consumption, electrical noise, functioning in extreme environments, etc. that may inform your decision to go with one controller over another.
