In any case, I shouldn't have said up front that I was about to be arrested, since that wasn't true. What was true is that I was about to do something illegal but managed to stop myself.

I have my own CA set up somewhere. Haven't "maintained" that for a while either, I think it's been a year since I generated my last cert

Rahul2001

@varfirstName no it isn't

You're getting confused

Bob

@Dog I actually have no idea what the 'standard' VPN is these days. I mean, there's OVPN and Cisco proprietary stuff, but... standards?

Rahul2001

You cannot impart joules on coulombs

Bob

IPSec? maybe

bwDraco

Alright, nothing happened. Let's move on.

Rahul2001

That's not how anything works!

ChatBot John Cavil

bwDraco

I'm learning to not dwell on things as long as I used to.

Dog

Basically, to access my home server/router/etc. instead of setting up a dynamic DNS and port forward on however many routers it goes through, my home server and router just autoconnects its VPN into my server server anytime it's up, and can be accessed via it's global LAN IP

Rahul2001

@varfirstName no, your terminology is incorrect

Dog

It's particularly useful if you have a very dynamic home IP, that can change several times a minute

bwDraco

var firstName

@Rahul2001 is amperage the kinetic energy of electrons flowing through a conductor?

Dog

6:13 PM

I'd better not touch that

@varfirstName No

Bob

just use icacls instead

Dog

Amperage is the number of electrons per unit time (well strictly speaking, amount of charge, in theory you can pass current without electrons)

Bob

@Dog Try these

    sc.exe sdset bits D:(A;;CCLCSWRPWPDTLOCRRC;;;SY)(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;BA)(A;;CCLCSWLOCRRC;;;AU)(A;;CCLCSWRPWPDTLOCRRC;;;PU)

var firstName

So the speed at which the electrons move?

Bob

(no don't actually run them)

Dog

6:14 PM

@varfirstName No.

Bob

support.microsoft.com/en-au/kb/971058

@Dog wpdev.uservoice.com/forums/…

var firstName

so the amount of energy that you can pass through a circuit in a given time?

Dog

@varfirstName No

@Bob Huh, now that you mention it, I'm sure there's a generic/open source *Nix SMB emulation layer somewhere

(AFS uses it for "native" AFS support on Windows)

var firstName

the amount of *coulombs you can move through a circuit in a given time?

Dog

@varfirstName NO

Instead of bothering with all the file system and layer abstraction, it just emulates a SMB server containing the filesystem it mounts internally

var firstName

6:17 PM

you said amount of charge per unit time

oh

Rahul2001

Yes

Bob

ahhhh now I need to figure out which ports I need to open for FTP

funfunfun

Dog

It's like... running a Linux VM with the filesystem mounted and a Samba server to share it with localhost

@Bob Active or passive? (Good luck with the former! :-P)

Rahul2001

@varfirstName Dude, chill out

var firstName

the amount of coulombs in a given second?

Bob

6:18 PM

@Dog passive, definitely :P

mobile/CGN => no way to do active

Dog

@varfirstName The amount of coulombs that actually moves across a circuit in a given second, yes

Bob

basically I need to figure out which port ranges to open in the Azure firewall

var firstName

OHHHH

Bob

but the lightweight ftp server I'm using doesn't list port ranges... -___-

Dog

Coulomb

The coulomb (unit symbol: C) is the International System of Units (SI) unit of electric charge. It is the charge (symbol: Q or q) transported by a constant current of one ampere in one second: 1 C = 1 A ⋅ 1 s {\displaystyle 1~{\text{C}}=1~{\text{A}}\cdot 1~{\text{s}}} Thus, it is also the amount of excess charge on a capacitor of one farad charged to a potential difference of one volt: ...

@Bob Yikes

Dog

I do recall having to faff around at some point to get my FTP(S/ES) server to work

var firstName

isn't ftp port 22/23?

or am I recalling incorrectly?

Bob

oooh I know I'll just open all ports restricted to my IP

Dog

@Bob lol

Bob

did I mention the lightweight FTP server also doesn't do encryption or authentication?

var firstName

6:21 PM

@Bob sounds like a public share on a server

Bob

meh, I'll take the bet that no one else CGN'd to the same IP will be trying to attack me

Dog

Huh. My FTP server (on Windows) doesn't have a specified port range either

Just listing the application in Windows firewall allows it to pass whatever dynamically requested port range through

Bob

@Dog what's the server?

Dog

@Bob Filezilla server

Bob

I'm using Baby FTP Server :P

@Dog Yea, Windows Firewall was easy.

var firstName

6:22 PM

@Dog so amperage is the amount of coulombs have passed through the circuit in a second?

Bob

The problem is the Azure (network security group) firewall.

Dog

@varfirstName s/average/actual/

@varfirstName Yes

var firstName

ok

Bob

oooh there's a built-in FTP rule I can select

...which opens 21 only. bleh.

Dog

Congrats, you've figured out what an amp is

var firstName

6:26 PM

so voltage is the potential difference in joules between two points when 1 joule of work is done to move 1 coulomb from 1 point to the other?

Rahul2001

@varfirstName Voltage is not in joules

var firstName

it's in volts

Rahul2001

What do you mean by "potential difference in joules"

var firstName

oh wait

Rahul2001

And you've managed to confuse me now...

Bob

6:30 PM

yay, I can connect! (21/control)

nay, I can't list directory contents (pasv/data) :(

Dog

@varfirstName No

Voltage is potential difference in volts. Joules is not volts.

var firstName

so in order to drive 1 amp through a 1 ohm resistor, 1 volt is required?

Rahul2001

I said that like an hour ago

3

Dog

I said that an hour ago

BRB restarting phone. Too many volume controls

var firstName

OK, tell me if this analogy is right:
in air, a rubber band can be pulled back 6 inches to shoot it 6 feet (very little resistance / drag / current requires very little voltage to be driven through circuit)
in water, the same rubber band can be pulled back to shoot it the same 6 inches (high resistance, equal resistance faced as the amount of force exerted, current requires equal driving force to oppose resistance)

Speed of electricity

The word electricity refers generally to the movement of electrons (or other charge carriers) through a conductor in the presence of potential and an electric field. The speed of this flow has multiple meanings. In everyday electrical and electronic devices, the signals or energy travel as electromagnetic waves typically on the order of 50%–99% of the speed of light, while the electrons themselves move (drift) much more slowly. == Electromagnetic waves == The speed at which energy or signals travel down a cable is actually the speed of the electromagnetic wave, not the movement of electr...

Meow?!

Dog

WinSCP is our "recommended" FTP/SCP application at my old workplace, and apparently better than Filezilla

Bob

@Dog that's what I had heard too, but when the damn thing locks up when you look at it funny...

var firstName

so it's instantaneous

?

Dog

@Bob Lol

I must admit I've only ever used it to take screenshots of it for documenting it

allquicatic

@varfirstName I think you can think of the "movement" of the energy (photons) in electricity as a large fraction of the speed of light (as it says, 50% to 99% -- even 50% is a relativistic speed), whereas the electrons are a "charge-carrier" or "medium" through which the photons move.

the electrons move too, but so slowly that if you could see them, you could follow them with your eyes

it would take a ridiculously greater amount of energy to move the electrons at the rate the photons are moving, because the electrons have mass -- a small amount, but some nonetheless -- and making electrons move at relativistic speeds is the domain of the Large Hadron Collider ;p

var firstName

7:35 PM

so does light jump between electrons? constantly?

Dog

@allquicatic As is "creating" charge (i.e. creating and annihilating electrons)

Urgh McDonald's hurts my ears

allquicatic

@varfirstName photons make up all electromagnetic waves, both "light" (what we think of light is just visible electromagnetic radiation) and "non-light" (microwaves, X-rays, gamma rays, etc.)

Dog

@varfirstName Electrons can absorb and radiate "light", and photons, yes.

That's how we know most of the universe exists

var firstName

yes, visible and the rest of the electromagnetic spectrum

from radio to gamma

That Brazilian Headless Horse

var firstName

7:37 PM

lol

allquicatic

but yeah, photons are frequently moving around between and being released from electrons

unless you've put some electrons in an absolute zero temperature environment

var firstName

Isn't that why we can see matter?

allquicatic

temperature is kind of a macroscopic sliding-window average of photon activity between electrons, for most chemical reactions (i.e. reactions that are not involving the strong or weak nuclear force leading to the decay or fusion of baryons (protons and neutrons))

var firstName

because photons are absorbed by electrons, which then reach a higher energy level, and then drop down to their normal energy level

?

allquicatic

@varfirstName essentially

Dog

7:40 PM

Astounded how he can understand electron energy levels and photonic excitation but not voltage

So that tiny bluetooth receiver has to be connected via that fat cable to that giant amp on the left to get any decent volume out of my Samsung phone -_-

Kinda hits the portability a little, don't you think -_-

allquicatic

electron energy levels are probabilistic though, from an experimental perspective; meaning, just trying to accurately measure them, changes them because the measurement affects the energy of the electron (and for most measurement devices, completely messes up the energy of many many other atoms' electrons nearby in really major ways)

Dog

@allquicatic Quantum physics makes my brain hurt

var firstName

yes, that's the idea of quantum computation

allquicatic

@Dog you sure it's not a miscommunication on flat volumes (AVRCP)?

var firstName

I believe it's called quantum superstate?

Dog

7:42 PM

@allquicatic IIRC Bob found out the S7 (or the Samsung headset?) doesn't support volume control over Bluetooth

var firstName

no superposition

allquicatic

IIRC Android has a whitelist for AVRCP flat volume support, and if your headset isn't on it, it reverts to no AVRCP flat volumes

meaning you have to tell your headset itself to turn up its volume, then turn up Android system volume separately

Dog

Either way, with the S7 and both volumes set to max the output is paltry. The S7's internal volume was fairly poor too, but a hack/update can fix that - not so the Bluetooth though :-/

@allquicatic Yeah, I did set both explicitly to max. The phone doesn't control the headset's volume and vice versa

allquicatic

heh... if the S7 is that broken in the UK, it probably still drops out and shit over here in the US -_-

Dog

It's not broken, well, at least the hardware isn't broken

I don't recall the bluetooth on my S7 ever dropping out, whether with my speakers, headset, or PC

The Bluetooth on my laptop drops out if I raise my hand (e.g. to put a fork in my mouth) despite the fact the laptop and speaker are both behind my screen and nowhere near my hand or my mouth.

allquicatic

7:44 PM

@Dog a little voice inside my head is going "HA-HA!!!" because iOS's bluetooth stack is so much better... the kernel's scheduler gives it better priority so it never drops out; the Tx/Rx gain is kept in a tight band optimizing power efficiency while ensuring excellent reliability and range; and it supports battery life indicator, A2DP AAC, and flat volumes for all headsets that offer the relevant profiles, with basically zero bugs all around

Dog

@allquicatic Unfortunately, you have to use an iOS device x-p

That Brazilian Headless Horse

What's a good guide between the differences of |, < and ` on the CLI?

allquicatic

on Verizon Wireless Android devices in the US, I think they embed some bloatware that fucks Bluetooth just badly enough in the ass that it randomly drops out; most people outside the US can't reproduce it. but Sprint users also get stuck with the same problem IIRC

Dog

@ThatBrazilianHeadlessHorse wat?!

allquicatic

@ThatBrazilianHeadlessHorse | is a pipe between programs; < transfers the contents of a file or block device into STDIN of the program to the left of it; and wrapping a command in the backtick character ` executes that command

Dog

7:46 PM

That's like asking for a guide on the differences between ping mkdir and exit

2

And chmod

Never forget the chmod

allquicatic

the only downside I've found between Android's BT stack and iOS's is that iOS doesn't (yet) support aptX, so if you're playing real time games on Android and comparing the latency to iOS, with supported aptX hardware, the Android game's audio will be more responsive

for listening to music, iOS wins hands down

Dog

@allquicatic I thought aptX was primarily to improve audio quality, not latency

> Qualcomm® aptX™ audio enhances the wireless sound quality of many of the world’s finest smartphones, speakers, soundbars, headphones and tablets. With aptX, music lovers can enjoy wired quality sound - wirelessly.

allquicatic

@Dog SBC and AAC have roughly the same latency (the better part of a second); aptX is a little better; and aptX Low Latency is fantastically wonderful (most people can't perceive aptX LL latency compared to wired analog)

var firstName

@allquicatic that makes sense, considering the iPhone was built after the business model of the iPod

Dog

@allquicatic Oh

No idea if anything of mine supports AptX low latency

allquicatic

7:50 PM

SBC = awful latency and pretty damn bad quality, though you can up the bitrate to make it sound less terrible

Dog

But tbh, I can't tell the difference between "regular" bluetooth and wired analog latency wise

allquicatic

AAC = awful latency and pretty great quality, depending on the bitrate

AptX = good latency and pretty great quality, depending on the bitrate

Dog

The only exception being my flatmate's Denon AV receiver which has like, 3 seconds of lag on Bluetooth, which is probably nothing to do with the Bluetooth and mostly the shitty receiver

allquicatic

AptX Low Latency = imperceptibly low latency and pretty great quality, depending on the bitrate

Dog

I think I previously had some bluetooth device/app/driver that reported the audio codec in use, but don't remember what it was

allquicatic

7:51 PM

I don't think most Windows stacks will report that info in an easy to find way, but BlueZ on GNU/Linux (or very old Android builds) will; so will Mac OS X

Dog

But personally, as much as I hated earlier bluetooth A2DP implementations' audio quality (circa 2005-2010) I've never noticed any latency issues on any <generic bluetooth device> and <generic bluetooth host> combination

allquicatic

I can definitely perceive Bluetooth latency for all but AptX Low Latency when gaming

Dog

I can't

Though the only "gaming" I've done on Bluetooth is probably STO ( a mmo with a shitty sound engine to begin with)
