DisplayPort provides 32.4 Gbps of bandwidth, 25.92 Gbps maximum throughput.
DisplayPort is a digital display interface developed by the Video Electronics Standards Association (VESA). The interface is primarily used to connect a video source to a display device such as a computer monitor, though it can also be used to carry audio, USB, and other forms of data. VESA designed it to replace VGA, DVI, and FPD-Link. DisplayPort is backwards compatible with VGA, DVI and HDMI through the use of passive and active adapters. == Overview == DisplayPort is the first display interface to rely on packetized data transmission, a form of digital communication found in technolog...
You'd need a 40 Gigabit Ethernet link to match that.

@JourneymanGeek except the buffering :P
funnily enough the actual flame parts are fine
not many changes over a static black background
but the guy talking... yea, that kills the bandwidth
00:21
soooo cell phone locking/unlocking. Each carrier has their own thing huh? I've done a bunch of researching this evening, so it seems apple keeps devices locked by sending their lock status to carriers?
because a geve MITM attack works by spoofing some number which is read off the SIM and sent to carriers hm. so does the iphone on bootup, okay this is very confusing
00:55
The disparity between desktop computing and mobile computing is flabbergasting.
Want to change the desktop OS? Just plug this USB and reboot. Change the mobile OS? Well...
Well... you could but you might brick. I mean equivelant of throwing a brick at your phone without scratching up the outside
@CausingUnderflowsEverywhere You tell me.

how so
how did you fling a brick

Yay. My first worldbuilding.se answer :P
@JourneymanGeek Moving computers again? :P
New tool for JMG's IT work:

Requires opposable thumbs..... :p
wow revolutionary.. NOT! he needs the one hwere the handles come out and has 4 wheels so it can be iether a trolley or a stand up thing
@JourneymanGeek Push for assistive technologies at your workplace!

The Motorola Defy, also known as Motorola Defy A8210 & MB525, is an Android-based smartphone from Motorola. It fills a unique market segment, by being one of the few small, IP67 rated smartphones available. It is water-resistant, dust-resistant, and has an impact-resistant screen. The phone has been launched unlocked in Germany, France, Italy, Hungary, India, Thailand, Spain, the UK, Turkey, Romania and Greece under various networks and is distributed exclusively by a number of carriers, including T-Mobile in the United States, Telus in Canada, and Telstra and Optus in Australia. An updated version...

o.O
It was accumulating dust in a drawer, until my wife's Lumia was stolen last saturday.
Turns out Android 2.1 + Motoblur = ~10s lag for a keypress.
With just WhatsApp and nothing else installed.
@ThatBrazilianGuy took 2 weeks to get us 4 newbies laptops... Powered armour for dogs.... :p
Bob
Bob
@ThatBrazilianGuy to be fair, whatsapp is shit :P
@Bob 150% of Brazilians, their brothers, mothers, aunts, neighbours and that guy from accounting use WhatsApp.
There is no escape.
Bob
Bob
02:24
@ThatBrazilianGuy I'm not sure if that's supposed to imply it's more or less crappy than I originally thought :P
It's no statement on its crappiness. Just on its ubiquity and unavoidability.
If you don't have WhatsApp, you lose on sales because everyone uses whatsapp for everything
People don't call radio stations or tv shows, people "zapzap" them.
@ThatBrazilianGuy Waterproofing is no longer a unique feature these days. It's becoming common on flagship phones.
It's a crappy 2010 phone that was forgotten in a drawer until last week 4 days ago.
heh.
02:49
You know what I hate about today's markets: exclusivity of products. The Galaxy S7 active is AT&T-exclusive here in the US. It's entirely possible that when Samsung approached carriers with the new phone, AT&T's offer mandated exclusivity ("either you do not allow other carriers to sell this phone, or we will not {pay you this much per unit | sell it at all}").
Similar discussion almost two years ago regarding a limited-edition variety of Pop-Tarts (be sure to click through for context):
Nov 3 '14 at 21:02, by DragonLord
I suppose this is what happened: Kellogg's approached several retailers with this product; Target came forward and said, "we will not carry your product unless you promise not to sell it elsewhere"
we are what we say we are until conformity hits us
@Bob whatsapp is telling me I need to upgrade my phone or something in order to continue using it
OMG I HAVE A BRAZILIAN FRIEND USING WHATSAPP

@bwDraco s/today/US/
<3 outright phones. contracts can go die in a fire
@Bob We've mostly moved away from the contract model.
It's device installment plans these days.
Bob
Bob
@bwDraco Also, I can see them just not bothering to make a CDMA model.
Okay, but aren't today's radios capable of operating on both GSM and CDMA networks?
All that's needed is a different baseband firmware.
Bob
Bob
@bwDraco Apparently not.
Different support chips, maybe antenna tuning, etc.
@PotatoCat mentioned it a while back... was news to me :P
The Nexus 5X and 6P, and Google Project Fi, are living proof that this is not necessary.
Bob
Bob
03:34
@bwDraco Oh, you mean the Nexus 5X that has an American model specifically for CDMA support?
Nope. It'll work on both CDMA and GSM networks.
Bob
Bob
@bwDraco I never said it can't work on both with one set of hardware. Just that the conventional, worldwide/international models don't bother including CDMA support.
Same baseband firmware, in fact.
Bob
Bob
Because no one else uses it.
You can grab any international GSM-capable model and use it on a GSM network (w/ band support, which can be a problem but usually there's at least one or two common ones).
You can't use the same phone on a CDMA network unless it specifically includes whatever hardware is necessary for CDMA support. Hardware that would be a waste of money to include in the international model.
Though, I'm sure there are some models where it is just a firmware limitation.
That makes sense now. It's getting late here, good night.
03:45
Whoot. Actual tech support....
(was busy updating the gold master image for my cloud server, which requires spinning up a temporary instance; hadn't done it in almost a year and involved an OS upgrade)
By far the cleanest system image yet.
Bob
Bob
@bwDraco Hm. I'm having a hard time finding a teardown comparing the H790 to the H791 :P
Aha!
> Depending on the model one or more of these chips are different to cover the different bands.
But, yea, sometimes it's just a firmware thing. More often when dealing with LTE bands, not CDMA enabled/disabled.
Wait, that's a terrible answer. That guy mixes 6 and 6s...
oh screw it
can't find a good source right now :\
pretty sure we've had this discussion before though
I do notice that the American H790 doesn't support the TDD-LTE bands, and it's lacking a couple of FDD ones too (B28, B38). Not sure if it's hardware. Think it probably is.
04:08
Hmm. Might be slightly different antennas. Probably the same radio.

A cloud gaming solution
Bob
Bob
meh, they don't work all that well
they have a data center very close to me. I'll check it out
they server is at ~600km to me and I can stream 4K on my internet and they stream the game to me as a video so I should be able to play 4k games without making my pc hot
now I just need to get fancy and get a way to play 4k games on cloud on my 4k TV with mouse/keyboard
Bob
Bob
...
I'll have to check when I get home, but I suspect you can't stream 2160p60 on even 100Mbit connections without significant compression
And real-time compression tends to be even worse
I only need 15MB/s-20MB/s to watch 4k on netlfix
Bob
Bob
@Freedo Which is probably 24-30fps, not 60.
And significantly compressed.
06:55
so 30-40 MB/s
Bob
Bob
Real-time compression is hard. It's hard to identify data patterns when you don't have access to future data.
That's leaving aside the whole latency issue *shrug*
Anyway, I'll have to check when I get home. Have a few clips of 4k gameplay at acceptable/high quality.
IIRC it was vaguely some 1GByte/minute, but I might've only been recording 30fps
Most games aren't random - you can predict a lot of future data according to the input. But I can handle anything upt to 120 MB/s just fine.
Bob
Bob
@Freedo Mbit, not MByte, I assume.
B means byte, b means bit
@Freedo Also, as far as the video codec is concerned, it can't see into the future.
This kind of encoding/compression has absolutely no knowledge of the game engine, game state, nor game inputs.
It doesn't matter whether any given game engine can theoretically predict the future; the video codec can't.
What if they just compress all the game, according to various input so they are just ready to stream ?
Bob
Bob
What?
The whole idea is the video rendering happens server-side and the display is compressed as video then played back locally.
07:02
Yeah, take a MMORPG as example
Bob
Bob
And?
you can predict a lot of actions, you can have then recorded and compressed
Bob
Bob
If you're going to start using game state, you might as well render the whole thing locally.
so if A user happens to request a sequence of actions already recorded you don't have to compress it
Bob
Bob
Doesn't work that way.
They use a generic video codec.
They do not specialise it to a specific game.
That takes an incredible amount of time and effort, for a very very niche use, and wouldn't exactly be much more efficient than simply rendering the thing locally anyway.
07:04
Uncompressed 4K video needs at least 7 Gbps bandwidth. (30 frames per sec)
According to a google research. Wow
Bob
Bob
Say you play MMORG #523. What makes it so special they'll spend the time (and many thousands of dollars) to specialise it for that game amongst the hundreds/thousands of others?
that would be like 14 Gbps bandwidth wow
Bob
Bob
@Freedo ...yea, definitely compressed.
Anyway. I'll check what a NVENC/ShadowPlay capture's bitrate is when I get home. About two hours from now.
That should give you some idea of the real bandwidth required.
(even that isn't perfect because these captures are compressed after it happens, not real-time... I think)
@Freedo Vaguely, the calculation is: 60*3840*2160*3
That's 3 bytes per pixel, with 3840*2160 pixels (4x that of 2k/1080p), 60 times a second.
~1.5GB/s, or 12Gbps. Uncompressed.
But usually you'd at least have lossless compression, if not lossy.
So the internet inst ready for 4k
Bob
Bob
One thing about compression is the more time the algorithm has, and the more knowledge about the data (past and future), the better it can get. Both in quality and size.
07:10
South Korea is starting to offer 1gbit/s internet speed just recently
Bob
Bob
If it has more knowledge about the internal state (as you suggested), it can compress even better, but decompression gets more expensive.
I still think cloud gaming is the future
Bob
Bob
Most games already kinda do a form of compression. It can 'compress' everything down to a very quick set of actions (kbps range), but the 'decompression' is the client-side rendering.
@Freedo Eh... kinda depends.
It actually works alright on a LAN.
Bob
Bob
Steam already offers that kind of streaming. IIRC Nvidia and AMD do too.
I've used it before.
But the compression artefacts are... well, fairly obvious.
07:13
Tho isn't that typically targeted at 1080p?
What do you mean?
Yeah I don't think even LAN can handle uncompressed 4k
Bob
Bob
So even on a 1Gbps LAN, it compresses it enough to be noticeable. You can see some blockiness, etc. Though that could be resolution... I need to try again.
@Freedo Never uncompressed, but I mean it compresses it to quite a noticeably low quality.
@JourneymanGeek Dunno, I tried it a couple years before I got 4k :P
Bob
Bob
@Freedo Based on my LAN streaming experience: quality isn't great. Latency can feel weird.
And that's going to be many times worse over the internet.
Some games would be fine. Others... not so much.
You can pretty much forget about playing FPSes like this.
Racing games too.
RPGs fare better.
But then RPGs typically aren't the most graphically-demanding in the first place :\
Of course, you'd have to try it for yourself to figure out if it works for you and the games you play.
But I wouldn't expect anything amazing just yet, especially not at 4k.
Maybe you can stick with 1080p30 for now, if 4k doesn't work out.
Oh, way back when, before all this gaming streaming and cloud gaming started up, I tried playing a game over RDP... it did not go well :P
Was over LAN, at something like 1024x576... got 4 FPS? With lots of screen tearing while it redrew :P might've been 1/4 FPS even
Think this was in 2010
Steam streaming, comparatively, even with the quality and latency issues, was much better.
That test was in... 2014? 2015?
@JourneymanGeek Oh yea, dunno if they've fixed it since, but it renders at host size and downscales to client size.
Which is quite nasty if you render at 1080p and scale to 1366x768. That might've been the cause of some of the quality issues.
I hate being born while Internet is still young
Bob
Bob
07:21
@Freedo All this said, I've only ever tried over LAN. Maybe LiquidSky has managed a better client and experience than Steam.
The fastest internet speed you can get right now is 1000mb/s
Bob
Bob
Won't fix the latency problems but it might fix quality.
Pen Pineapple Apple Pen
Bob
Bob
@Rahul2001 Oh god. Please do(n't?) link that video :P
@Freedo Yeaaaaaa no. Unless you're really lucky :P
Google fiber or South Korea
Bob
Bob
07:23
Yea, that falls under lucky :P
Funny how we've barely even managed storage capable of 1GByte/s.
Funny how Internet doesn't follow moore's law
@Bob lol
Bob
Bob
@Freedo That would be because the bandwidth limits aren't that closely related to transistor count...
morning
Bob
Bob
'lo
07:28
It's also funny how even google probably doesn't have enough storage to store all possible combinations of a 63 characters of A, a, 9-0 and symbols :P
they probably do
I don't think so. I learned that other day in the class...a text file with all combinations possible of 15 character password with symbols, A-a and numbers can easily grow into petabytes of storage needed
What? Seriously?
you can do the maths
Bob
Bob
@Freedo Permutations and combinations are a funny thing. Factorials are a funny thing.
07:33
1 character = 8 bits (1 byte)
Bob
Bob
Of course, it's trivially compressible given a specialised compression algorithm.
I tried to use Crunch to calculate the storage needed for a wordlist for that password and it failed to calculate it :D
Bob
Bob
@Burgi 63!? That's excluding the combinations of len < 63.
Just all permutations is somewhere around 2.0x10^87 of them.
I can't remember the formula for combinations.
Oh yea that's right, combinations is where order doesn't matter. Whoops.
@Freedo try wolfram alpha
That's funny
a 63 characters password with letters, numbers and symbols has a search space of
3.99 x 10^124
Bob
Bob
07:38
@Freedo Is that exactly 63 or up to 63?
I'm not sure
Bob
Bob
I think exactly 63 is 63! is 2 x10^87 as above.
I think it's up to 63
Yeah I'm sure even google can't store that wordlist :P
ffs
https://www.wolframalpha.com/input/?i=63!+*+87
You still cannot calculate the storage needed for that
Bob
Bob
07:44
@Burgi Wait, why are you multiplying by 87?
I tried google and it gives 7.935438e+124 bits
you've got 63 character positions and 87 different charaters that can occupy those positions
Bob
Bob
Oh, that's right.
Whoops.
you can also use high ANSI characters
Bob
Bob
...looks like I need a stats course refresher
Forgot about the whole repeating character thing. Bleh.
07:47
you'll need 9.9193×10^114 GB (gigabytes) to store that wordlist so yeah not possible
Bob
Bob
@Freedo You can compress it to under 100 bytes.
Decompression just takes forever :P
Programming Puzzles & Code Golf can help you with the compression part
Eh. I should head home. Still gotta look up that video bitrate.
google should just buy wolfram
they didn't want to
why not
it doesn't make money
07:55
like most of everything google does
@Bob I think it renders 1080 borderless window on a 4k screen....
@Freedo everything google does is to make better adverts to make more money

Oh dear. Review Queue is > 1800
it says 1.2k on my screen
08:59
@Burgi Hmm
does that include the close vote queue?
@Burgi it is the total number of posts awaiting review (and it is cached). When you look at the individual queues you see the numbers that can be reviewed by you personally (those numbers don't include the items you have already reviewed).
Does that make sense?
yeah
@Burgi What I don't understand is you seeing 1.2k. Where do you see that?
09:15
Ah. OK. That means there are 1.2K first posts that you could review. I have 823.
@JourneymanGeek User superuser.com/users/647032/radisson-blu is posting spam questions and answers.

Hi, are there any desktop operating systems which allow widgets? For example, on my Android phone, I have my email/calender/weather/music player etc all as widgets, so I can see the next few items in my email/calender etc, or create a new email or play a song etc. Is it possible to acheive this with a Desktop app (ideally Windows).
10:32
@Dave window 7 has gadgets
You can get them on windows 8 too, but not 10
Bob
Bob
@Dave Technically, you can get "widgets" on Windows, Linux and macOS.
Just grab the third-party widget provider of your choice.
@JourneymanGeek dat jpeg
@Bob freeze them
Bob
Bob
@Rahul2001 ...and cut them how?
@Bob with a knife
Then they don't make you cry when you cut them
I had no... idea...
10:35
@Dave about onions or widgets?
Thank you @Bob
Thank you @Rahul2001
I've understood about onions... They are... gits
Bob
Bob
@Rahul2001 I don't exactly make a habit of cutting ice with a knife :/
@Bob it doesn't get that hard
<shrug>
@Bob I tend to stick em in water
Why do we cry? Is it due to the fumes being breathed in or the fumes "touching" our eyes?
I do all cooking at home and they don't bother me 95% of the time, but if my wife is in the room it will affect her 90% of the time! Really odd
@Dave That's easy to test. 1/ Wear swimming googles and breathe normally 2/ No goggles and hold your breath :)
ha ha, yes, true... but if some one were to see me doing this, they'd probably argue I shouldn't be allowed near sharp knives @DavidPostill
@Dave It's the eyes. "When you cut the basal plate or shoot, they release an enzyme. That enzyme reacts in the rest of the onion to release a gas. When that gas combines with water, it creates an acid. If that water is in your eye, you have acid in your eye. "
wow.. .now we know :)
Bob
Bob
11:00
@Rahul2001 Ice is slippery and I'm clumsy with a knife. Not a good combo.
In other news, I'm now missing a chunk of skin off a finger...
@Dave Touching. Different people have different sensitivity.
@Bob I hope you aren't cooking a vegetarian meal ...
Bob

@DavidPostill ohhhhh, chill them, not freeze them (cc @Rahul2001)
@DavidPostill Hah, nah, more sliced into than off.
@Bob, I think you're doing it wrong
Bob
Bob
@Dave ?
The slicing
I think you cut your finger, but I doubt that's what is supposed to happen
:D
11:08
@bob
@Bob Stops you crying and is also finger safe!
i cut onions underwater
@Burgi I cut onions. 99% of onions don't make me cry. Occasionally I get one that does irritate my eyes ...
Seems like a lot of effort, to get changed and essentially go swimming just to cut an onion
lol
a bowl of water will do
I once spoke to Jean Christoph Novelli (some TV chef in UK) and he said it's the membrance which is what causes the issue - so cut it at the correct angle and you're fine
11:13
@Dave What's the correct angle then?
213
Q: How can I chop onions without crying?

lomaxxOnions are an excellent addition to many dishes, but cutting them can be frustrating when they make you "cry" all the time. Does anyone know any tips or tricks to help minimise the tears when chopping onions?

I should have known there would a SE answer ...
Solution #1: Get someone else to cut them ?
lol
Sometimes I can think ouside of the box; that can lead to great solutions.
@DavidPostill the one which doen'st make you cry :) I guess it's about not messing the mebrane so I guess it's about having a sharp knife to ensure a cleaner cut
12
Q: Can you develop an immunity to chopping onions causing tears?

JolenealaskaI just chopped a particularly strong onion, I noticed some slight irritation but no tears. I realized then that onions haven't made me cry for years, decades even. I use all kinds of onions and take no special precaution to prevent tears. I don't refrigerate them, remove the core, use goggles, li...

11:20
Ha ha, David and I are super humans... It's a thing with all David's / Dave's I think you'll find.
i'm waiting for onion 1.2 which removes the irritant
All are just... brilliant
JUst use tor for the onnion.
@Hennes lol
peer to peer onion slicing

You guys are geeky

yeah and?
A fume hood (sometimes called a fume cupboard or fume closet) is a type of local ventilation device that is designed to limit exposure to hazardous or toxic fumes, vapors or dusts. == Description == A fume hood is typically a large piece of equipment enclosing five sides of a work area, the bottom of which is most commonly located at a standing work height. Two main types exist, ducted and recirculating (ductless). The principle is the same for both types: air is drawn in from the front (open) side of the cabinet, and either expelled outside the building or made safe through filtration and fed...
he he.
That's the geeky solution. Combine cooking and chemistry

@DavidPostill Hah, nah, the finger incident wasn't onion-related.
A particularly slippery piece of ginger and my knife got into a disagreement. The ginger won. And the knife took it out on me.
You have to watch out with those gingers...
Bob
Bob
Did I mention I'm clumsy with a knife?
That reminds me. I am out of ginger juice.
(Just put lots of it into a fruit juicer. COllect the dust. Freeze it into cubes. Very handy to use)
Bob

@Bob or fax
teletype!
since they need my manager to physically sign the damned thing
