My apologies, I missed a few of your questions at the end.

  • Yes, any USB4 rated cable can carry the TB protocol at whatever distance it’s rated for, otherwise it isn’t USB4.
  • Likewise any TB3 cable should work for your application, if it’s actually TB3 rated.
  • 3m is generally the max length I’ve seen. The theoretical limit may be higher but I suspect latency of the cable itself becomes a problem for PCIe tunneling, which is still a synchronous interface TMK.
  • The TB controllers decide whether your cable is sufficient. They will negotiate a link if they can both verify a nominal link speed/multiple. So the lower rated USB cables won’t work for PCIe tunneling, even if your ultimate bandwidth requirements are minimal.

A few things to note if you’re shopping on places like AliExpress, eBay, Amazon, etc:

  • Be wary of any long (active) TB/USB cable that’s cheaper than $30.
  • Be wary of any cable that has a small connector, like one you would use to charge your phone, because the TB/USB4 connector itself must house an active signal repeater chip, making them chunkier and/or longer than usual.
  • Similarly, the shielding requirements are fairly substantial, so the cable itself should be beefier than most USB cables.
  • IME generally, PCIe over TB/USB can sometimes just be finicky. Of the 12 or 13 cables I’ve used with various combinations of machines, enclosures, docks and risers, there are occasionally some combinations that just don’t play nice, for whatever reason.

You may need an active TB3/4 cable. 30 cm is typically the longest passive cable you’ll see. Active cables are more expensive, though less so than they used to be, and can handle longer runs like 3 meters.

Agreed. I do miss having an especially thoughtful and couth figurehead representing us on the world stage, just someone we could generally be proud of.

Of course that feeling was especially pronounced when the following act was and is a global embarrassment and weirdly consummate avatar for all our worst qualities.

Shave their belly with a rusty razor?

I hear you. To be clear I wasn’t accusing the new user of ill-intent, certainly not of racism, or even implicit bias. As you said, Obama is commonly regarded as a world-class orator, so it’s just true, and also would bother the tangerine palpatine who speaks in crayon.

It is merely insensitive, and likely due to a lack of awareness, which is why throwing a flag right away is preferred, especially in a forum where black people are less well represented (for now).

As to why it is insensitive: while it’s usually meant as a compliment, noting that a black person is well-spoken — especially when using the word “articulate” — happens to summon a long history of people being surprised that black people can speak so well. And while this example of racial insensitivity isn’t as well-known in popular culture as, say, blackface, it is not at all obscure. The links I posted above are a tiny sample of the articles, books, and memes pertaining to the subject.

In other words, simply using the phrase “articulate black man” unironically is enough to strongly suggest the author is oblivious to the fact. And judging by all the downvotes on my comment (and now throughout my comment history lol) I’m guessing many others in this forum are oblivious to it as well.

So I threw a flag, partly to make the user aware of the insensitivity, partly because I suspected many others in this forum might be similarly unaware, but mainly because I’d prefer this place be welcoming to everyone.

Of course, union battles are a matter of history. And yes, today the rational agents of global economies often see unionization as a threat, clearly.

I argue that it’s only a threat insofar as it’s a disruptive paradigm. On the whole it’s a more fiscally advantageous schema for all but the monolithic “vertically integrated” international corporations that profit largely from self-dealing (and probably need to be broken up anyway).

You said businesses prioritize “Control” and “Power” over profit — i.e. they are not rational economic agents but despots. It’s a bleak perspective since despots can’t be reasoned with, only overthrown, and moreover it dismisses economic theory entirely.

I’m just weary of the defeatism. I know we’ve been through a lot and many of us are terribly jaded, but giving up is not an option. I want to win.

Right and it’s just code switching. People of all races do it without thinking. The dominant strain of English in the US can sound “white” to urban poc, “academic” to rural white people, or “yank” to white people abroad. It’s only loosely associated with aggregate identities.

Here in NYC, at least in my neighborhood, code switching is constant and routine.

That is fascinating. It makes a lot of sense. They’re safe to point out when the emperor has no clothes.

OK just so we’re crystal, I’m only interested in fixing what’s broken. I have no time for doomerism, tedious conspiracies, or despair.

At the expense of profit? If control is preferable to operational stability, why do so many businesses use IT vendors?
