hi

Hennes

PCIe will get a massive power increase at the connector. Solomon couldn't recall the exact ceiling because member companies have proposed several options. Solomon stated that the minimum would be 300W, but the ceiling “may be 400 or 500W."

allquicatic

@Hennes holy cow

imagine a 500W dual Titan X-P board O_O

Hennes

So, if I have a 4 slot PCI-e motherboard they best start selling with bigs PSU or disappoint people

allquicatic

@Hennes mobos don't come with PSUs but they have PSUs on the market that could probably drive that (maybe not all four slots maxed, but close)

Hennes

18:04

Pushing that much power though the motherboard seems a bad idea.

Hopefully those PCI-e slots will come with their own PCI-e power connectors

djsmiley2k

heh needing 2.kw psu for that lols

Hennes

Also Connecting External Devices Through A Standardized PCIe Cable

Why do I have to think of Thunderbolt ?

bwDraco

@Hennes That'll be the end of PEG power connectors \o/

Hennes

Not for a while yet though.

First PCI-e v4.0 is all relevant machines

E.g. a new graka should have them for backward compatability

bwDraco

@Hennes What? The limit does not exist at all (the one-sided limits differ!)

(+Inf from the right, -Inf from the left)

Clearly she doesn't know what infinity means :\

allquicatic

18:30

@bwDraco hence the joke

bwDraco

But the limit of 1/(x-8) as x approaches 8 is not infinity. It doesn't exist; the one-sided limits differ.

Hennes

The joke is still funny though.

allquicatic

@bwDraco Yup

bwDraco

A math problem from a game Father played a while back:

> The Book of Equilibrium

A sound knowledge of mathematics is required to practise the arcane arts. This puzzle will test the applycant's knowledge of all thyngs mathematycal. Place the weights in the chests, ensuring that you use each and every one, or the entrance will remain sealed for all time! [There is a total of 13 iron weights and 20 lead weights.]

Place twice as much iron as lead in Chest 1.

Place the same amount of iron in Chest 2, then add 1 more. But place twice as much lead in Chest 2 as you place in Chest 3.

It so happened that I was studying linear algebra at the time this puzzle came up.

Express as a system of 8 equations in 8 variables and reduce the matrix to RREF.

I even emailed my professor about it.

Math can come up in unexpected places...

@Hennes yeah, well, that's not gonna happen so soon

for consumer hardware PCIe 3.0 I dont recall any gear which would even approach the throughput limit

and based on how fast the industry innovates lately, we wont see any v4 hardware before 2020 (unless a miracle happens and AMD begins the brethren Intel's dominance)

Hennes

PCI-e v3 seems to already bottleneck some SSDs (NVME, x4, PCIe v3)

bwDraco

...and 8 lanes would require too many pins.

allquicatic

yeah, the first adopters of PCIe v4 would be enterprise SSDs :P

either that or they'll start making x16 SSDs

Dog

@Hennes Maybe for reads, not that pure STR matters at those levels, but certainly not for writes

@allquicatic They already did: anandtech.com/show/10125/…

allquicatic

19:24

oh ok

bwDraco

Enterprise SSDs can already saturate PCIe 3.0 x4:

Dog

I can't think of a single application where PCIe 3 x4 storage is a real bottleneck... Most things are random IOPS bound not STR limited, and who the heck puts a single SSD into a high-performance enterprise server?

Hennes

As a home user I best not ask about the prices for those :)

bwDraco

(testing the SOCKS proxy on LTE right now, running an errand)

Dog

Heck even mid-range Dell servers a few years ago supported 4-8 PCIe hot swap SSDs

But the data all has to go somewhere... and frankly, very very very few applications are going to be able to process 20GB/sec... heck you're almost at the limits of what can be sensibly handled by the system RAM!

bwDraco

Sep 30 '15 at 21:26, by DragonLord

The fastest consumer SSDs already exceed 2.5 GB/s. Only a matter of time before consumer hardware hits the 4 GB/s limit on PCIe 3.0 x4.

What about GPU arrays? AMD CrossFire uses the PCIe bus.

allquicatic

@bwDraco yeah, that could possibly be a boon for AMD

bwDraco

(since R9 290X)

allquicatic

I think you're better off (for now, at least) running a dual-GPU card, though.. they need a Polaris or Vega "X2" card

the R9 295X2 was technically the fastest card on the market (for many benchmarks, though not all) right up until the Pascal release

Nvidia hasn't done a dual GPU board for a while, have they?

Dog

@allquicatic Only cause the Fury X2 hasn't shown up

@allquicatic Last I recall was the Titan Something? Z?

Two years, one and a half generations ago, wasn't that long

TBH the 295X2 still equals or beats the GTX 1080 half the time

Dang

£370 used, well that's a steal if you don't pay for electricity >_>

Hennes

Some more fluff from the net:

allquicatic

19:39

notch is a little crazy

Dog

Wait wtf, why are there five conductors inside my headphone cable

allquicatic

would that be some kind of digital volume control or mute sw?

stereo output, stereo input, and...

Hennes

Mute, mic, answer the damn phone button, ...

Dog

@allquicatic There's only four contacts on the plug though :-/

allquicatic

the new Office 2016 for Mac update is 64-bit native... this should be interesting

Dog

19:52

I guess it might be two ground lines, one to each side.

I'd have expected that the ground wire was split at the junction thing where the cable splits, but looks like it's actually in the 3.5mm plug

Well fuck. The reinforcing string in the cable is so strong I can't cut it

allquicatic

@Dog well-designed product prevents user vandalism :D

Dog

It's not vandalism when it's already broken

Burgi

@Dog when are you de-canining?

allquicatic

> Woof. I'm a cat.

not quite sure what he is

Dog

Wait it actually has SIX conductors o_0

There was another sneaky one wrapped up inside the fifth

allquicatic

20:08

that is an animal which (if it existed; that's shopped) would truly say "Woof. I'm a cat."

Dog

I've figured out what they do!

!!s/I've/I think I maybe/

ChatBot John Cavil

@Dog I think I maybe figured out what they do! (source)

Paul Vargas

@Dog What's that?

Dog

@PaulVargas I don't know, I'm a cat

Paul Vargas

@Dog A cat?

A cat with a Dog name?

Dog

20:15

I didn't pick the name

Paul Vargas

var firstName

@Dog Who did?

Dog

The Moderati

var firstName

The triangle dudes?

better watch out, dude

Mokubai

@Dog Dude, we could choose a much more appropriate name for you if we wanted

Dog

20:22

@varfirstName No, the diamond dudes

var firstName

diamond dudes? :o

DavidPostill

@Mokubai That reminds me. Do you mind sharing what your name means?

allquicatic

It means wood-many ;-D

Mokubai

@Dog I dub thee "The CatMan!" (sung to the tune of youtube.com/watch?v=FE0XcdM22Yo)

DavidPostill

@allquicatic In what language?

var firstName

20:23

Japanese?

allquicatic

@DavidPostill I was kidding. In Japanese, "moku" is wood, and "bai" is a counting suffix for certain types of things (it's complex)

long ago I called him wood-many

Mokubai

@DavidPostill It is a noise/word that came to my head some many years ago. @allquicatic has since bacro-named it.

var firstName

@Hennes Will you be my imaginary friend?

Hennes

Are you sure you want that? I can be irrational.

var firstName

I don't know, as a square, you seem pretty rational to me.

Hennes

20:26

You do not know my roots

var firstName

Don't be so negative

DavidPostill

Q: What happened to the plant in math class?
A: It grew square roots.

Q: Why do plants hate math?
A: Because it gives them square roots.

var firstName

@DavidPostill No, it grew cubed roots

DavidPostill

So I poured my root beer into a square glass...
Now I just have beer

Mokubai

@DavidPostill So, what does your name mean? ;)

var firstName

20:30

David After-Sick

4

Hey guys

guess the meaning of my name ;)

allquicatic

I get it. Post-ill! haha

var firstName

Thanks, @allquicatic; I'll be here all day

DavidPostill

@Mokubai David = Beloved, Postill = Apostle

var firstName

In what language, @DavidPostill?

allquicatic

we can call you BA maybe

BelovedApostle1746 could be one of your alternate screen names

*googles*

var firstName

20:34

Did you mean 'giggles'

allquicatic

why 1746? why, the year Adam Weishaupt was born, of course

DavidPostill

@varfirstName Greek.

surnamedb.com/Surname/Postill

allquicatic

@varfirstName no

DavidPostill

@allquicatic It isn't.

var firstName

wait

allquicatic

20:36

@varfirstName OK! ;-) (in JavaScript there's no waiting)

only async

I think I unwittingly got an award just now

Ben N

I once tried to mimic synchronous XHRs in JavaScript by doing a busy loop after invoking it, but the state never changed :/

DavidPostill

20:37

@Mokubai You still haven't answered my question - or is the Japanese thing the right answer?

Ben N

And also it crashed two of the three browsers I tested on

var firstName

Pun-city

"@DavidPostill It is a noise/word that came to my head some many years ago. @allquicatic has since bacro-named it."

Mokubai

@DavidPostill When I chose the name it had no meaning. It was just a name I chose, and it stuck.

DavidPostill

@Mokubai Fair enough. I didn't choose my name. It also stuck :)

Mokubai

I had it for some time before I joined this site.

var firstName

20:40

I didn't choose my name either

it was variable, so I decided I would rather be null than undefined

@DavidPostill in your experience, is there any such thing as revenge-downvoting?

Dog

Yes. Ramhound does it all the time.

Also dang, looks like the actual earphone driver is bust

:-(

var firstName

Oh my god, I thought so.

I tried to tell him he was misunderstanding the question (in the comments), and next thing I know, my answer has -2 points!

Dog

Now the question is should I cut the cord off the replacement and replace it with a straight ended plug, voiding the warranty straight away?

DavidPostill

@varfirstName Hasn't happened to me AFAIK. I have been serially upvoted though ...

Dog

Moral of the story: Never try to tell him anything. It won't work.

var firstName

20:45

Alright.

Here's the thread in question: superuser.com/questions/1116424/…

Jesus!

@varfirstName I think your answer was actually downvoted because, in its original form, it didn't address the question asked

var firstName

74£ postage?

bwDraco

20:48

(iftop is now running in a screen session to survive unexpected drops in the underlying SSH connection)

DavidPostill

@varfirstName 1/ Your answer has been downvoted twice (two different users). 2/ You don't know it was RH (voting is anonymous).

var firstName

@bwDraco sorry for being a little bit late to the party; what is this?

@DavidPostill I understand that, but @Dog answered saying that @Ramhound is known to do so.

DavidPostill

@varfirstName When he does he usually comments as well (as fat as anyone can tell) ... although that might have changed due to recent events ...

var firstName

@DavidPostill 'recent events'?

Ben N

It must be tiring to always get replied to with "WHY DID YOU DOWNVOTE MY ANSWER?!" - I am moderately frequently accused of downvoting things I didn't just because I happened to have a comment on them

It makes me a lot less likely to tell people how to improve their stuff :(

DavidPostill

20:55

@varfirstName Somebody got very upset with him.

var firstName

Sorry for that negative experience, @BenN, I was just inquiring of the tendency as a known behavior.

Ben N

He does tend to downvote a lot, but also casts a boatload of upvotes

I'm sure a reasonable chunk of my own reputation is from him

var firstName

@DavidPostill Ah, I understand, details unnecessary.

He's very stubborn, I've noticed.

Alright, I'm off work in two minutes

Dog

You know who else tends to downvote a lot?

God.

God is doG backwards.
