Unfortunately a great many of them use Sodastream’s gas cylinders - after their patent expired and anyone could build a compatible unit - so you might not be able to escape them getting your money when buying CO2 refills, if there isn’t another brand of gas cylinder available where you shop.

Sodastream have released a new cylinder design (with a bayonet rather than screw fitting), presumably to again attempt to kill off the market for home refilling from a larger CO2 cylinder, or use in other brands of machines.

All of that said, I do like my Aarke machine.

Damn, that was a chonky update. 17GB download, 85GB of files touched.

The website also shows a large unpopulated section of PCB near the network jack with “PoE” silkscreened:

PoE built in could make this a very interesting device indeed.

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.

When you’re eating off-brand loose meat, you might well find that it is horse.

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.

Can also recomment “Sqwincher” (stupid name aside) products.

As they market primarily to people working in construction / other trades - and are therefore sold at the likes of electrical and safety supply stores - we buy them in bulk for when we’re spending weeks installing racks of servers in our datacentre at 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.

My last laptop (owned from 2013-2020) had an NFC reader under the touchpad.

I managed - exactly once - to get my phone to send a file to it using Beam. Did everything exactly as expected; initiated the transfer by NFC and sent the file over Bluetooth.

I could never repeat the experiment. Once, and only once.
