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.

it’s essentially 2 PCI Express x1 lanes and USB 2.0

Sometimes there’s only a single PCIe lane though. And as you say, that’s not a x2 but explicitly two x1s.

No WiFi card needs the bandwidth (yet), at PCIe 3 speeds you’ve got around 7.8Gbps for a x1, and PCIe 4 double that.

The Coral comes in a “dual” version for exactly this reason (https://coral.ai/products/m2-accelerator-dual-edgetpu/) you just have to be very sure the slot you’re putting it in is actually delivering two PCIe connections.

Also for bonus fun, most WiFi/BT cards use the PCIe interface for the WiFi and USB for the Bluetooth.

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.
