> DACs are copper, and they're happy.

Yeah, but DACs are pretty short and tend to have much thicker cables than regular copper Ethernet.

Yes, the decryption happens in hardware. For your OS (and potential capturing software running on it) the place where you see the video is just an empty canvas on which the hardware renders the decrypted image.

I think the noise emissions of a successful launch already make it an unattractive and potentially hazardous (for your hearing) place to live, especially considering SpaceX' launch frequency.

> AMD supports it on all chips

Unfortunately not. I can't say for current gen, but the 5000 series APUs like the 5600G do not support ECC. I know, I tried...

But yes, most Ryzen CPUs do have ECC functionality, and have had it since the 1000 series, even if not officially supported. Official support for ECC is only on Ryzen PRO parts.

They have a video where they have an eInk display show video at 60 Hz. In contrast to a previous video, where the display was running at 2.4 Hz and the video then sped up by 10x, this is not sped up. What kind of black magic is this?

> As you'd expect, the embryo was only tiny and measured just 27cm long.

27cm is not exactly what I would call tiny. For comparison, this is what Wikipedia has to say on the topic of ostrich eggs:

> on average they are 15 cm (5.9 in) long, 13 cm (5.1 in) wide, and weigh 1.4 kilograms (3.1 lb)

It's almost twice as long. Talk about megafauna.

Looking for alternative sources, I found this:

> The unhatched dinosaur’s 24-centimetre-long skeleton is curled inside the egg, with its head tucked tightly into its body. The egg is 17 centimetres long and 8 centimetres wide.

( https://www.newscientist.com/article/2302492-fossilised-dino... )

Okay, so they were talking about the size of the dinosaur if it stretched out of its curled position inside the egg. The egg meanwhile is a little larger than an ostrich's egg. Still not tiny by any means, but slightly less mindblowing.

The BSDs have diverged significantly since then and not just in userland. Unlike Linux distros they do not all have the same kernel. There are of course common parts in their kernels, many of which date back to Unix, but there are also big differences between all of them.

I was also surprised to see Sailfish OS, Meego and Maemo listed separate from Linux, but my guess would be that the list comes from the build system of curl. Everything that is its own build target is listed there.

I recently used this (via https://depenguin.me/) to install FreeBSD from a Linux Rescue Image on a Hetzner root server. Hetzner sadly discontinued the FreeBSD Rescue Image.

This installation method uses KVM to boot the mfsBSD image, giving the VM the actual hard drives to install on. The one thing that tripped me up was that the network interface presented to the VM did not use the same driver as the physical network interface. So the FreeBSD installation configured (in my case) `em0`, but once I rebooted into FreeBSD, the network interface was `igb0`.

> Surely they can transfer data through water efficiently enough?

Actually, no. Water absorbs most of the electromagnetic spectrum pretty well, severely limiting the communication range. So you're limited to low frequencies or acoustic communication. Both have a low bandwidth, so forget live video footage.
