@varfirstName you'd rather they used vpn tunnels?

It's not virtual

djsmiley2k

I had powerline at home and it worked

DavidPostill

@varfirstName Shouldn't that be "Voorhees"?

var firstName

yes...

funny thing is, I live next to a town named that

Unbelievable how i fucked it up

DavidPostill

Make sure you spell it right for the t-shirt printing then :)

Voorhees

Voorhees may refer to: == Places == Voorhees Township, Kansas, located in Stevens County, Kansas Voorhees Township, New Jersey Voorhees (CDP), New Jersey, located in Somerset County Voorhees Mall — a section of Rutgers University's College Avenue Campus in New Brunswick Voorhees State Park, New Jersey == Buildings and institutions == Voorhees Chapel, the college chapel at Jamestown College in Jamestown, North Dakota Voorhees Chapel (Rutgers), a college chapel on Rutgers University's Douglass Residential College campus in New Brunswick, New Jersey Voorhees Hall a building on Rutgers University's...

@varfirstName I'm confused.

Wouldn't their method of 3 routers on teh same coax do some bad stuff

1. collision domain?

var firstName

Yes.

djsmiley2k

2. Some other stuff I'm too young for general usage of coax

allquicatic

@KronoS Thirty? Me too. Well I'm 8/12 months through 30 and I can say it's pretty alright.

djsmiley2k

32 here

at least I think I am

yup, 32

var firstName

@djsmiley2k not to mention, with no managed switches, packet loss will be in the 60s at least

djsmiley2k

8:07 PM

I've realised I don't care for myself anymore, all i do is for my kids :O

@varfirstName so how would powerline be worse?!

var firstName

I wasn't saying it was worse

djsmiley2k

from what I understand of the question, they'll be having 3 internet ocnnections into one property

allquicatic

on a scale from -10 to 11, where -10 is being tortured and/or locked in solitary confinement and 11 is having a limitless harem and being hand-fed the finest grapes while doing nothing but experience utter hedonism at all hours of the day, I'd say 30 for me in middle-class suburban America is about a 7.1.

djsmiley2k

Oh, haha

ok, so what are you disagreeing with?

@allquicatic I'm finally feeling like if I come off my drugs it won't be the end of all things.

Been a long time since I've felt that.

Hennes

I think I'll need a few days running window 7 updates.

djsmiley2k

8:11 PM

@Hennes just randomly reboot it too

i've found that helps, from patching hundreds of clients here

Hennes

Oh, did that.

var firstName

@djsmiley2k how's my response?

djsmiley2k

Tho we're pulling from a WSUS server at least

Hennes

As did a shutdown and restart, since the last time I installed things that helped while a few reboots did not

djsmiley2k

@varfirstName already upvoted your answer :D

var firstName

8:12 PM

Thanks

djsmiley2k

I get the feeling someone tried to tell them to get repeaters or such, and they didn't understand.

var firstName

ikr?

feel bad for the sap

djsmiley2k

Or the model of router they have may function as a repeater too? I don't know as not looked

yah but some people do this 'Oooh i want to do X I'll spend lots of money then find out how'

var firstName

dropped $500 on 2 shitty APs and a router comcast already gave him

djsmiley2k

I had a friend who'd do it, and also some other stupid things... I remember him killing a Voodoo 3D gfx card by shoving it in his PC then powering it up, forgetting the oncard power and it some how died

he'd kinda shrug, and go out and buy another one

var firstName

8:14 PM

@djsmiley2k if you read my answer, I tell him to investigate his routers' settings to see if it has that function

djsmiley2k

yup, hense the upvotes :)

var firstName

if only some of postill's magic rubbed off on us all

djsmiley2k

hmmmmmmmmmm

15 min since the last seat came off hte line

DavidPostill

@varfirstName ???

but then he'd cease to exist from the intense friction of 65k reputation pulling away from his chiseled mass

DavidPostill

8:19 PM

o_O

djsmiley2k

D:

what's the mass of 64k rep?

gawd I stink :/

this place is ick

DavidPostill

0 - it's all imaginary points

djsmiley2k

@DavidPostill it's still bits

bits have mass

Hennes

I hate sites where you click on the download link and it takes you back to the same page you were on

djsmiley2k

I just hate downloads

var firstName

8:23 PM

@djsmiley2k yes. They have 1/8040th of the mass of a proton

that's 1/8040th of one amu

shit

thats so light

but not light enough to be a photon

So i've got a question for all of our cogsci guys

DavidPostill

@djsmiley2k Does Information Have Mass?.

var firstName

does electromagnetic radiation still take the form of a photon at the level of radio waves or gamma rays?

DavidPostill

the minimum mass change a one-bit flash memory, when flipped into bit value 1

var firstName

shit

thats <1e-

**<m^e

djsmiley2k

hmmm

var firstName

8:29 PM

oh fuck it

djsmiley2k

so basically almost zero

:D

var firstName

no

quite far

djsmiley2k

But, the change of charge means there's mass then

DavidPostill

the mass is negative if one defines the erased memory element to be a MOSFET with charged gate!

djsmiley2k

So while you're adding up all the points, there's mass, until you get the final figure D:

hmmm

var firstName

8:31 PM

Hey yall

djsmiley2k

so a charge of -1V, has no mass?

surely that's wrong

it's just 1*mass, same as 1V would be

mass comes from difference from 0 energy?

var firstName

@djsmiley2k actually no, -1V doesn't exist

-1W does

djsmiley2k

It doesn't?

var firstName

so does -1A

Voltage is the power

djsmiley2k

erm, what's the -12V rail do then? :/

var firstName

8:32 PM

Current is the direction

djsmiley2k

I'm not a electrican :D

var firstName

current is like velocity

djsmiley2k

yah\

bwDraco

8:57 PM

@djsmiley2k The voltage is relative to ground. +12V means that there's a positive potential compared to ground; -12V means the opposite.

The -12V rail is considered redundant these days as circuits can be designed to simply use +12V instead, but legacy systems may still need it.

Besides, at least one of my PSUs doesn't like using any of the two non-ground rails together for even light loads. If I try to drive 17V or 24V (by connecting +12V and -5V or -12V), or even 7V (+12V and +5V) through any device, the PSU just shuts down.

Q: What is the usage of the negative voltages on a PC motherboard?

What is the usage of theses negative voltages? Are they there only for backward compatibility? In nowadays PC power supplies, we have: +12V +5V +3.3V but also: -12V -5V But the current rating of the negative rails are much smaller than the positive ones. If we were back to the 80' where...

power-supply

djsmiley2k

Nod

so basically -12V is the same as 12V but... upside down

;)

bwDraco

The problem is that devices will now have to derive negative voltage using just a positive rail and ground, which adds complexity to the device. However, it's a rather unusual situation in practice.

var firstName

@bwDraco Voltage is like the payload, and Amperage is like the velocity of the payload, right?

bwDraco

Not exactly. It's the other way around.

Power supplies "push" voltage but devices "pull" amperage.

var firstName

Voltage is how much is being sent, amperage is how much that voltage is being pulled

right?

bwDraco

9:12 PM

They're not the same, though.

var firstName

i'm confused

bwDraco

Power is a combination of voltage and amperage. The power supply is responsible for delivering the correct voltage; the device pulls only as much amperage as it needs.

djsmiley2k

voltage is the b/w, amps are the packets

var firstName

waitwaitwaitwaitwait

djsmiley2k

wait nope, that doesn't work :/

var firstName

9:21 PM

so in SC2 terms

djsmiley2k

y can't things be simple!

var firstName

My assimilators hold the voltage

and my drones pulling the gas to my base are the amperage

So, how outrageously long is my reply to this OP asking about using 3 routers to extend coverage in the house.

Before you begin reading my answer, please note that my understanding is that you wish to use these routers as independent modems broadcasting on the same SSID with the same WEP/WPA(2) key, and same settings.

DavidPostill

@varfirstName Seems OK enough. I'm not completely sure whether what the OP wants to do is possible though. I agree with mtak that pulling new cable is the best solution.

var firstName

9:53 PM

Except OP despises running cable

it seems

DavidPostill

@varfirstName "I really don't want to dig into the walls and run cabling throughout the house." is not the same thing as "I don't want to pull new cable". That doesn't require digging into walls.

var firstName

pull new cable?

djsmiley2k

tie ethernet to teh end of the coax and pulllllll

lol

DavidPostill

Exactly.

If the Coax was installed correctly in conduit that should be very easy to do.

djsmiley2k

my house is so annoying in that respect

we have ethernet between a few places

var firstName

my house has no ethernet w/se

A: Why is it that Microsoft Excel says that 8^(-1^(-8^7))) = 8 instead of 1/8?

That's incorrect. -1^2 is 1. However, -1 to any odd power is -1; that is true. Using perfectly sensible logic, you can say that 8^(-1^(-8^7)). -8 ^ 7 = -2,097,152, an even number; therefore, -1^(-2,097,152) is 1/(-1^(2,097,152)) which reduces to 1/1 or simply 1, and 8^1 is 8.

Ramhound

@varfirstName - Do you know the difference between 2^-1 and -1^2?

In your answer you wrote -1^2 which is equal to 1.

DavidPostill

@varfirstName @ramhound The whole question is meaningless as there are 2 ( and 3 ) so the expression is invalid.

Ramhound

You even said it was 1.

no kidding

lol, I am looking for excel, forgot I had not installed it

var firstName

Yes.

I do.

2^(-1) is 1 / 2

(-1)^2 is 1

I said no such thing

Ramhound

10:43 PM

Why mention this then "That's incorrect. -1^2 is 1" what does that have to raising any number to -1?

var firstName

OP said:

DavidPostill

I'm voting to close this question as off-topic because 8^(-1^(-8^7))) has mismatched parentheses and is therefore an invalid expression.

var firstName

> Now -1 to any power is -1

Ramhound

....

var firstName

so that means, in every circumstance, -1 as the base, exponent n as any number, -1^n = -1

which is FALSE

that's what I was disputing in my opening sentence

his logic is flawed

-1 is always assumed to be an integer unless a set of parentheses isolate the minus.

Ramhound

10:47 PM

yeah, alright, confusing statement honestly.

var firstName

yep.

agreed.

Ben N

The formula gives the same results on Excel 2016, if that matters at all

(once I remove the extra trailing parenthesis that is)

DavidPostill

@Ramhound @varfirstName @BenN

var firstName

@BenN OP is wrong.

DavidPostill

Ben N

10:49 PM

Yep, Excel corrected it too

Dog

I'm hot

DavidPostill

It can be corrected in two different ways. We don't know what the OP meant.

var firstName

@DavidPostill -1 is always assumed to be the entire integer

unless intentionally split using a set of parentheses

Ben N

In math, negation always happens after the exponentiation though IIRC

var firstName

@BenN it's not negation. You don't multiply a number by positive one just because it is positive, nor do you multiply by -1 just because it is negative.

ALSO, big thing to say here, the minus needs to be before the beginning of the exponent to be included in a final negation.

an integer is always taken at face value

Ben N

10:55 PM

I just checked a scientific calculator (TI-84) and -2^2 evaluates to -4

Ramhound
