"I bought this before Elon went crazy"

No, no you didn't, he was just better at hiding it. But now that you're all caught up, glad to see you're doing the bare minimum.

I got into an argument with someone once about this, when they told me (paraphrasing) "it's safe to drive listening to music through headphones, because they let outside sound in".

Yes they indeed might, but - even ignoring delay introduced from digital electronics - you've now lost all sense of where that sound is coming from, because you're listening to the sound of one microphone being played through one speaker.

The human ear really is an incredible thing.

Generally, you just need to export the pool with zpool export zfspool1, then import again with zpool import -d /dev/disk/by-id zfspool1.

I believe it should stick after that.

Whether that will apply in its current degrated state I couldn't say.

While I have a personal general rule against backing electronics on Kickstarter and would likely wait for it to be available at retail, I wouldn't necessarily immediately discount this one.

It's probably worth noting - mentioned in Jeff Geerling's video - they had a MOQ of 1500 on the metal case, which likely forced them to be significantly further through the process than a lot of Kickstarters are at launch.

Indeed, you will note that they carefully chose the moniker "Daily Active Uniques" and not "Daily Active Users".

I think that speaks volumes, as humans are definitely harder to retain.

My first time hearing that word too, but apparently: https://en.wikipedia.org/wiki/Truckle

late Middle English (denoting a wheel or pulley): from Anglo-Norman French trocle, from Latin trochlea ‘sheaf of a pulley’. The current sense dates from the early 19th century and was originally dialect.

Putting a solar roofs over any open-air carpark you happen to own is just a hilariously easier option. Hell, you could erect these OVER the train tracks.

https://greenox-group.de/photovoltaik-carport/ (Article is in German, but it's really more around the picture)

According to a completely un-sourced picture I found online, one carpark (in the USA) is typically around 5.5 x 2.6m, so if you had even 50 carparks on your site you could have ~715 square metres of panels. More, if you figure a way to cover the aisles between the rows of carparks too.

At the top end of all applicable figures (panel efficiency, solar irradiance, inverter efficiency), that could net you ~160kW at solar midday.

Now on the other side, standard-gauge railway is around 1.4m wide, and maybe you could cram a 1m width of panels between the rails.

That sounds like a lot - 1000 square metres per kilometre, and there are thousands of kilometres of railway lines out there - but it's harder to install, harder to service, gets dirty faster, is liable to get damaged, and now you have to figure out how to extract power from somehing a kilometre long, instead of an area that could be a square only around 35m (~115') on a side (for the above 50 carparks).

I know which one of those I'd want to run the cables for.

As has been pointed out many times when this dumb-ass idea comes up, only once you've exhausted every other possibility (carparks, rooftops, putting panels ABOVE roads/rivers/canals/cycleways/railways) and have literally no other viable installation locations, then we can talk.

Per the article... yes

While the price is undoubtedly an issue, I'm concerned this wasn't higher up in the article

Brownlee says the money from the app is split 50/50 with artists

HALF? Like I get that people are going to sign up to get exposure, but that is a hefty premium for doing very. very little work.

It sounds like you're thinking of LoRa, another 900MHz radio protocol.

LoRa has similar bandwidth to Zigbee (125kbps), and as you say is designed for low-power devices running on battery. I have PIR motion sensors at home which have used only around a third of their battery after 2 years.

Security cameras seems to be a large target market for HaLow though, where you need a couple of megabits at a few hundred metres.
