@HardwareGeek also it's an active Thunderbolt 4 cable.
I know the video discusses the 2 metre version but IIRC the 3 metre version is the only certified Thunderbolt 4 cable over 2 metres.

I know nothing about Thunderbolt (and care even less), so I didn't pick up on what version it is, but yeah, being active is obvious from the components in the connectors. Why Thunderbolt needs so much complexity in a "cable", . It sounds like they've moved some of the high-speed interface circuitry that would normally be in the device into the cable, so instead of paying for it once, in the device, you pay for it in every cable you ever buy.

Who needs such a long cable anyways?
-
@HardwareGeek apparently people wanted the ability to add external high end video cards or something that would normally latch onto the system bus.

No, it was actually before that was a craze, something about being able to upgrade hardware without upgrading the main machine. Like adding higher-end video cards to iMacs or something. But I digress, it's a way of taking something other systems already did better and cheaper, and productizing it the Apple Magical and Revolutionary way.

Why Is Apple's USB-C Cable $130?
TL;DW: Because it's not a USB-C cable; it's a Thunderbolt cable and has a bunch of Apple proprietary stuff in it. It may be compatible with USB-C, but it's != USB-C.
The comments pointed that out too. But it was still pretty interesting.
edit: The first 1/2 of the video talks about the Apple cable. The 2nd half talks about Amazon's USB-C cable and a couple of really cheap cables. (Adam also goes off on a rant of "WTF are there so many different types of USB-C and no way to tell them apart"
-
@dcon I lost interest and stopped watching before that point (some time during the Amazon cable, when it was obvious they were comparing apples and oranges).

Always wondered a bit about these, now it makes a bit more sense.

TL;DR: the picture.
My headset's charging cable has a little symbol has a way of indicating it's for power only. It might be standard, I don't know. It should be standard anyway.

@Tsaukpaetra I wish I knew more about electronics, and electricity in general. I kept read on it, but it doesn't seem to stick.
-
@Zecc you read up on it but the knowledge just flows in and out again?
-
@Arantor It's like something in me resists learning it, like it's beyond my capacities.
-
@Zecc either put more force behind it or try to reduce the throughput of energy maybe?

What you need is formal induction.

@Watson Any of you terrible electrical punsters happen to know the voltage of a cattle prod? Want to find out?

Between 2.5kV and 8kV.

I am failing to parse this sentence.

@HardwareGeek I was being flippant because one of the subjects of the video, that is a blatant plagiarist, has a habit of trying to subtly reword things to make it sound like he didnât write them, and ends up mangling the content.
Itâs a video essay about other essayists that are also varying levels of plagiarist.

The section about James Somerton is amazing. I just got to this bit.

If I put together the next two or three minutes I would never stop talking about it.

Blooms are 3-D printed sculptures designed to animate when spun under a strobe light. Unlike a 3D zoetrope, which animates a sequence of small changes to objects, a bloom animates as a single self-contained sculpture.
The bloomâs animation effect is achieved by progressive rotations of the golden ratio, phi (Ď), the same ratio that nature employs to generate the spiral patterns we see in pinecones and sunflowers. The rotational speed and strobe rate of the bloom are synchronized so that one flash occurs every time the bloom turns 137.5Âş (the angular version of phi).
Each bloomâs particular form and behavior is determined by a unique parametric seed I call a phi-nome (/fÄŤ nĹm/). -John Edmark

I Was SCARED To Say This To NASA... (But I said it anyway) - Smarter Every Day 293

@dcon I'm a bit of two minds about this. Obviously, it's a nice speech (despite being quite long and I skipped some parts) and thanks for sharing it.
But then the main point is, basically, "the new Moon mission is too complicated." And yeah, he makes the point pretty well with a lot of small examples. We've already been to the Moon, so we have a proven design, why do we redesign everything and add layers and layers of complexity?
(and then a lot of nice stuff about learning to think differently, asking the difficult questions etc.)
But then again, we do have that design, so if we spend as much effort as the Apollo program did, we can build a lot on top of that design. And why would we not do it? The whole point of Apollo was to go to the Moon. That's it. Not any further, not do anything there (yeah, yeah, we brought back a
lousy t-shirtfew rocks but that wasn't really the point). And he shows a chart about how through the missions layers and layers were added towards that goal.But the thing is, we're doing the same here. We're not going to the Moon just to get there, we're going there to... actually I'm not sure what the next step is, building a permanent base? go to Mars? (well that may be part of the communication problem, that it's not clear to the general public (me!) what the overall goal is) So going to the Moon is one of those successive tests that adds bits and bits. We're not starting from the ground and trying to replicate Apollo. We're starting from Apollo and trying to go further.
So there's a lot more complexity, OK, sure but... Apollo was way more complex than anything before. So it's not obvious to me that NASA is really doing it wrong.
Still, nice video and interesting thoughts there. I learnt quite a bit I didn't know about Artemis.

I liked this. Nicely done.

@Arantor I think I posted it in the Songs thread. Very classy.

Okay, maybe a little dumb in its content, but what a great little animated short. They don't make them like this anymore. The soundtrack complements it perfectly as well.

LoRa packets by banging a pin on a microcontroller. Uses some aliasing tricks (overtones) that I don't quite fully grok yet to make something way less than 900Mhz create a 900Mhz-ish signal. From a few 100m to a bit over a km (with ridiculously low transmit power).
Aside from being really cool, lots of potential here.
