My reaction to PCIe gen 8 is essentially "Huh? No, retro data buses are like ISA, PCI, and AGP, right? PCIe Gen 3 and SATA are still pretty new...".

I wonder what modulation order / RF bandwidth they'll be using on the PHY for Gen8. I think Gen7 used 32GHz, which is ridiculously high.


> PCIe Gen 3 and SATA are still pretty new...

That's an interesting thought to look at. PCIe 3 was a while ago, but SATA was nearly a decade before that.

Wikipedia says it's planned to be PAM4 just like 6 and 7.

Gen 5 and 6 were 32 gigabaud. If 8 is PAM4 it'll be 128 gigabaud...


I'd highly advise against using GHz here (without further context, at least), a 32Gbaud / 32Gsym/s NRZ signal toggling at full rate is only a 16GHz square wave.

baud seems out of fashion, sym/s is pretty clear & unambiguous.

(And if you're talking channel bandwidth, that needs clarification)

Is it for PCIe 5.0? PCIe 6.0 should operate on the same frequency and doubling the bandwidth by using PAM4. If PCIe 7.0 doubled the bandwidth and is still PAM4, what is the underlying frequency?


PCIe 7 = 128 GT/s = 64 Gbaud × PAM-4 = 32 "GHz" (if you alternate extremes on each symbol)

for gen6, halve all numbers


Is it me or are they using the term GigaTransfers wrong? They're counting a single PAM4 pulse as two "transfers".


They kinda are and kinda aren't, they're just using their own definition…

(I'm accepting it because "Transfers"/"T" as unit is quite rare outside of PCIe)


GT/s is also gaining ground for system RAM in order to clear up the ambiguity that DDR causes for end-consumers.


And it's a good way to remove the ambiguity of things like DDR, but ugh "transfers" is not the best word here.

Looking at some documents from Micron I don't see them using GT/s anywhere. And in particular if I go look at their GDDR6X resources because those chips use PAM4, it's all about gigabits per second [per pin]. So for example 6GHz data clock, 12Gbaud, 24Gb/s/pin.


Would you rather go back to the modem days and call a 'Transfer' a 'Baud'?

PAM encoding is already analog, and also correspondingly more expensive (power, silicon size, etc) for the increase in speed.

It really wouldn't surprise me if even on workstation platforms only a subset of core lanes were Gen6+ and the common slots were redriven Gen5 or less off of a router / switch chip.


> Would you rather go back to the modem days and call a 'Transfer' a 'Baud'?

We don't have to go back, baud is still in use. I would expect transfers per second to be a synonym for baud though, and for bits per second per pin to use a different word.


Aside from GDDR for GPUs, DRAM is still mostly specified with MT/s rather than GT/s, probably because marketing prefers bigger numbers. It'll probably fall off once 5-digit numbers become commonplace.


> baud seems out of fashion, sym/s is pretty clear & unambiguous.

Huh? Baud is sym/s.


Yes, that was the implication, but I've been getting the impression that using baud is kinda unpopular compared to using sym/s.


A lot of people think that baud rate represents bits per second, which it only does in systems where the symbol set is binary. People got it from RS232.


IIRC, modems never went much beyond 2400 baud. Everything past that was clever modulation packing more bits onto a single symbol.


Huh, I never thought of it that way but you're right.


Don't forget VESA Local Bus.



His "The Shepherd" is amazing. Linking a PDF of it (it's 29 pages, and 100% worth reading) and not the wikipedia page for spoiler reasons: https://www.cessna150152.com/ubbthreads/attachments/13553-Fr...


Saving it up for the weekend. Thanks for sharing!


"Wi-Fi calling" (LTE over IP over wifi) often allows you to get SMS messages over wifi only, on an ordinary cell plan: https://support.apple.com/en-us/108066 (Android supports it too)


The article mentions that they've encountered problems receiving messages from short codes via that.


There are even multiple services that will mail a Potatoe to the recepient, possibly anonymously: https://potatoparcel.com https://www.mailaspud.com https://www.anonymouspotato.com https://mysterypotato.com (the only one I have used is "anonymouspotato").


Are they services or just middlemen who turn around and use USPS?


It looks like they put the potato in a box?


>(More surprisingly, there is evidence that lead is an essential micronutrient in trace quantities but its biological function is not currently known.)

Do you have some links about this? I found some papers re arsenic but I can't find anything re lead.


The amount of slop on Google has ruined everything, it is hard even for me to find papers and I know about it. But I do have a starting point for you:

https://pmc.ncbi.nlm.nih.gov/articles/PMC2246629/

It is genuinely surprising but there is evidence for it.


>it was 30 or so shots into my stomach, given over multiple days - and causing a lot of soreness and pain in between. I wonder if it’s still like this, because damn

it's not like this anymore; it's just four shots in the upper arm (like any other common vaccine) over two weeks.


There has got to be some sort of two-man rule (https://en.wikipedia.org/wiki/Two-man_rule) integrated into the system that can't be bypassed by the people with authority to make changes to accounts. Otherwise any insider / careless spear-phishing victim will make the changes they want.


Looking into vitamin K2 (not K1) along with vitamin D is interesting as well -- I got my bone mineral density to 99th percentile (DEXA measured) without changes in physical activity (which has just been walking) with lots of K2 and vitamin D; with the vitamin D from sunlight and a UVB phototherapy lamp when I wasn't getting lots of sunlight. My sense is that bone and teeth health are at least significantly related and I bet having excellent bone density carries over to caries, or to a lack thereof.

My guess is that typical Western diets are pretty subpar in terms of vitamin K2 intake (modern Westerners aren't usually fans of liver etc) which makes teeth pretty vulnerable to physical/chemical insult.


If there are plants (there is a patent and a paper describing this in some algae, IDK if it has been replicated or not...) that have preferences (kinetic isotope effect!) for one isotope of uranium over the other you could technically have a uranium enrichment plant made from uranium enrichment...plants.


Possibly relevant:

https://www.geochemicalperspectivesletters.org/article2333/ - "Contribution of the nuclear field shift to kinetic uranium isotope fractionation", Geochemical Perspectives Letters v27

"By following the fractionation of 233U, 235U, 236U and 238U during the enzymatic reduction of hexavalent U to tetravalent U by the bacterium Shewanella oneidensis, we provide the first direct evidence of the nuclear field shift effect during biologically controlled kinetic isotope fractionation."


Have a feeling this kind of idea is born secret


It's not like you can just buy some uranium to experiment with in your home lab, so even if a normie had this idea they would probably not be able to test it in any way.


You actually can. Small quantities of natural or depleted uranium have no special nuclear regulations associated with them in the United States and can be shipped like other moderately toxic metals.


Theres 4.5 billion tons of the stuff in seawater. Enough uranium to make 70 billion little boy bombs if my math is right, using an algae perhaps you’ve designed to accumulate uranium.


Reminds me of Marooned in realtime, where near the end of civilisation, individuals have the firepower of entire nation states of the past.
