The newer AMD cards are pretty good value at the moment, but when they first came out, they were a lot more expensive cause of demand
 
yea, bloody miners!
 
@MichaelFrank: on the bright side, they'll likely upgrade and you can get cheap, one gen old cards? ;p
 
AX6970 a good buy?
 
12:41 AM
@PearsonArtPhoto I've got a 6850 that runs really well. So it's probably not a bad buy.
It benchmarks slightly lower than the GTX560
 
Hmmmm...
Depends on which 560.
 
@PearsonArtPhoto: eh, the OC varients (and TOP varients for asus) are just better binned processors
and depends on what you use it for
 
Ahh yes, sorry. I have a 560Ti. So I was comparing to that.
 
Well, I've decided it, I'm going with the 6970.
 
blah
I'm trying to work out if a question is too simple ;p
 
1:00 AM
In the mean time, I just have to glance at my monitor, and kill KSP if the temp gets to be too hot...
 
Waiting just isn't an option...
 
1:18 AM
@PearsonArtPhoto in Q4 2014 I couldn't recommend buying a VLIW graphics card anymore
too bad if you've already placed the order; but that GPU ISA is just obsolete, sorry
you really need a GCN if you're going with AMD.
which means a 7000 series, 8000 series or R7 / R9 card
(careful with the 7s though, since some of them are re-brands of the VLIW5 chips)
 
AMD's Graphics Core Next (GCN) architecture has taken the graphics world by storm; it's currently in the top two premium consoles (the Xbox One and the PS4), and offers a very balanced performance profile, doing very well in physics and bitcoin mining in the GPGPU arena, and shaders in the graphics arena; it's also got the best price-performance ratio available. it's AMD's most significant change to their graphics architecture in 5 years.
having a VLIW5 card that you've owned for a while is fine; that just means you're getting value out of a past purchase... however, buying a new VLIW5 (pre-GCN, that is) card at this time is inadvisable, because it will be obsolete within the lifespan you expect the card to last for, if you purchase cards on a 3 or 4 year cycle.
 
that worked well. I'm switching between systems sharing the same monitor by turning off the monitor in command line in one, and mouse jiggling the other
 
@JourneymanGeek noice
 
@allquixotic: very ugly
and blah, the new box is too nice to use as a stick in a cupboard server.
 
1:25 AM
stick? cupboard? :P
 
lol
@allquixotic: figure of speech. Basically as a headless system quietly running stuff without anyone noticing
 
ahh

I don't have any cupboards with ethernet access. :<
 
I'll be rebuilding it eventually (stuck one of my old new stock 40gb hard drives on it for now, I'm probably swapping it with a 1tb laptop drive))
@MichaelFrank: I don't either. I should
 
Bob
...1gb laptop drive?
Is this a laptop from the last millennium?
 
1:38 AM
my bad.
I was wrong by a factor of... quite a bit
(which, in effect, gives it more storage than the two drives in my current download box)
 
@Bob XD

Q: Don't know what to do

Erin RaySo I met this guy, a couple weeks ago, he called me pretty and I never met the guy so I rudely ignored him but my brother-in-law is good friends with him and he says he's a good guy etc. after he told me that I looked him up on facebook and decided I would message him and ask if he remembered me,...

uhh...
 
@MichaelFrank @GFSE @Sathya Uhh... ;-)

Uhh...
There really isn't any other appropriate response.
 
should I be baleeting it?
Yes, I should.

Q: You can close a list of ports with nmap?

user3680708Good day, I have a server on debian 7 which has a number of open ports, of which only occupy 5 closed need everyone else, there is a command to close multiple ports? or I have to close one by one?

 
@JourneymanGeek a day like a Limp Bizkit song?
 
Bob
@JourneymanGeek first comment is more correct than yours - ports are closed unless explicitly opened
 
@Bob: probably!
 
Bob
2:37 AM
iptables is used to block ports (or "stealth" them if you use it to drop)
still looks like a closed port externally, I guess
but if they're open it's better to deal with the source :P
 
mod abused.
;p
 
3:09 AM
hm
turns out the main source of noise on my old atom now is the PSU
(also mental note. Installing a speed reducer for a chipset fan while the case fan is running is stupid and painful)
and blah, I am dumping ubuntu soon
 
Bob
Yay!
 
GET IT OUT! GET IT OUT! (the Ubuntu)
 
@allquixotic: don't you even want to know why? ;p
 
sure, tell me why
 
acpi bug pegs out the processor at 100%
so I need to run echo disable > /sys/firmware/acpi/interrupts/gpe00 each time
 
3:23 AM
ew
 
and I had the problem on at least two different versions/releases
 
Bob
What are you moving to?
Makes me wonder if Debian has the same problem.
 
oh wow that guys has a lot of rep!
 
Bob

Bleh System process is hammering my I/O constantly
How do I find out what driver(?) is causing this ?
 
@HackToHell: what OS?
 
Windows 7
 
Resource manager?
 
12:15 PM
Yeah but I have no idea what's causing System to do that much I/O
IT peaks suddenly and dies down in 10-15 mins :/

1:56 PM
blah
I think the cpu on the bay trail isn't supported yet on fedora
 
er, it should be?!
 
the heaven benchmark gives me a white screen and glxgears seems vsync locked at 60 fps
 
oh. you mean the GPU?
better ninja edit / mod abuse your previous statement
also, a low-end Intel iGPU not working on Unigine Heaven is hardly a surprise
 
Bob
@allquixotic It's more the "wildly fast" in the previous statement
 
I mean the GPU
oops
 
2:01 PM
I'd be surprised if Unigine Heaven would run at all even with git master mesa and Linux kernel and Xorg DDX, on Haswell Iris Pro
 
the FOSS graphics stack is pretty elementary; it always has been -- alpha quality, and always about 5 to 10 years behind the binary blobs
even Intel's proprietary driver on Windows isn't that good compared to Catalyst and Nvidia's driver
Catalyst and Nvidia driver are fairly competitive, but every other GPU driver implementation is years behind both
 
also the vsync thing is intentional to prevent tearing, I think
 
2:04 PM
it's enforced by the compositing window manager, not by glxgears
 
ah hah
Its running a DRI driver (good) but KDE's control module for Opengl detects the 3D accelerator as "unknown"
 
which is not surprising
parsing the OpenGL vendor string is a crapshoot, and Mesa changed theirs recently
recently enough for KDE to bug out when trying to regex it
the OpenGL version string is not supposed to be parsed by a program; it is just an arbitrary string of text returned by calling a function in the OpenGL API
 
there are no semantics enforced upon the format of the OpenGL version string
 
(and this probably shows how long its been since I've used a actual linux install with X)
 
2:06 PM
it could say "we here at Intel really enjoy the fact that you purchased our CPU! btw, the driver version is zero point three five, or thereabouts"
or it could say "AMD FGLRX 14.06"
or it could say "I jump on grapes five times a week!"
2
 
lol
hm. I probably shouldn't be expecting this to behave as well as my nvidia, yes :/
 
you could file a bug on the bugtracker that mesa uses, but I have a feeling that the issue you have with Unigine Heaven is due to entire swaths of missing functionality in the driver itself, rather than being hardware-specific
 
ya ;p
I think the fact that I'm using opengl 3.1, direct rendering and composited desktops working should mean that things are working
 
even the highest-end Intel GPUs, even the ones that haven't been released yet but already have a huge amount of driver support in the open source graphics stack (Intel employees contribute code for unreleased GPUs), are still sitting somewhere between OpenGL 2.1 and 3.0 support
 
@allquixotic If I'd expect anyone in RA to jump at grapes, it would be @Bob, not you
 
2:15 PM
this seems to support 3.0
 
at this point a full OpenGL 4.0 implementation with relatively few defects is probably 5 years off for the open source graphics stack
 
@JourneymanGeek the declared OpenGL version is completely separate from what the driver actually supports
 
@allquixotic: ....
ITS ALL LIES.
 
from what I recall, the Mesa OpenGL core supports the 3.0 profile fairly well (but with bugs in specific drivers and many performance issues), but the real problem is the extensions
 
Bob
2:16 PM
@ThatBrazilianGuy specist :(
 
there's the core OpenGL API, which is useful enough but doesn't let you get the most performance out of your card... then there are the extensions, most of which are invented by Nvidia and AMD and published in muttering, vague specifications on the Khronos website (some not even published at all)
big projects like the Unigine engine will use these extensions liberally to get higher-end graphics and perf
 
@Bob I am no specist! I treat all dogs, foxes, cats, racoons and even yellowballs of the chat room all the same!
 
maybe I'm asking the wrong question
 
the open source graphics stack can, and does, implement many many OpenGL extensions
but it's still years behind supporting most or all the ones the binary blobs do
 
2:18 PM
"How do I check that that I'm using the 'right' driver, and I have any opengl support at all?" ;p
 
there aren't enough people working on the FOSS driver stack for it to ever catch up
@JourneymanGeek if glxinfo doesn't say something like softpipe or llvmpipe or throw an obvious error, you have hardware OpenGL support.
 
@allquixotic: I was under the impression intel did put quite a lot of resources into it, other than the powerVR based cards
ahh
 
is this the latest release of Fedora?
 
just making sure, because every 6 months the open source graphics stack advances as much as cars advance in 15 years
 
2:19 PM
I'm running FC20, and I'm not uncertain about it
 
despite the fact that Mesa makes tons of (rapid!) progress every month on improving the drivers (fixing bugs, adding features, performance optimizations, etc), the binary blob teams are still moving much faster than Mesa, which means they'll never catch up
 
(even if the codename is heisenburg)
 
you have to be that xkcd "cake is a lie" guy to really use the FOSS driver stack
 
!!xkcd lie
 
2:20 PM
assuming there's any linux games that old!
 
Portal 1 works well on the FOSS stack
 
@Bob See, now I'm an animal too (A Brazilian animal, nonetheless!)
 
I'll try it when I manage to work out how to install steam on fedora ;p
 
Bob
@ThatBrazilianGuy no less*
 
2:23 PM
basically any first-generation Source Engine game will run at 60 FPS on a high-end Intel chip on the FOSS stack. Example: Iris Pro 5200. Bay Trail, probably not, because of hardware limitations (few Execution Units), but Iris Pro could definitely tackle it. EASILY.
 
and I really need to get a decent wireless mouse/keyboard bundle. The tiny keyboard and ancient mouse I use on it are killing me
 
Valve helped Intel and VMware fix bugs in Mesa and DRM to support the source engine better :)
 
@allquixotic: hm. glquake!
 
and yes, VMware. Brian Paul, the original author of Mesa, works for VMware after they purchased Tungsten Graphics
VMware continues to be a major contributor to Mesa and the FOSS graphics stack in general
 
dosen't tungsten graphics write drivers for intel?
 
2:24 PM
(it also helps VMware support 3d acceleration in Linux guests)
 
ah hah!
 
@JourneymanGeek Tungsten Graphics is no longer a company.
they use their company name in some old drivers though ;p
also, "Gallium3d" is a technology that was invented at Tungsten before it was purchased by VMware
all FOSS graphics drivers except Intel's driver use Gallium3d
Gallium3d is basically a userspace library that implements a bunch of common infrastructure to reduce the amount of lines of code required to create a graphics driver for new hardware
Intel thought their approach was better, so whatever
fortunately Gallium3d has no impact on the Linux kernel, so there is one, unified, Direct Rendering Manager stack in the kernel that handles the low-level device specifics and provides the userspace libdrm library, which is called by both Gallium and non-Gallium drivers
the benefit of Gallium is that you can write a minimally working, slow but functional OpenGL 2.1 driver for new hardware with about 2000 lines of code in userspace, plus around 10-15k in the Linux kernel (Gallium doesn't help with the complexity on the kernel side, unfortunately) -- by comparison, a minimal bringup on Intel's driver would require about 20 times more code in userspace
the drawback of Gallium is that it imposes a bit of overhead
Intel's driver doesn't use Gallium so it doesn't eat that overhead, but it also doesn't get OpenGL extensions implemented only on top of Gallium.
of which a few exist, thanks to AMD's driver being on Gallium, and the AMD employees contributing to the FOSS stack writing many extensions for their driver :P
 
... 2008?
damn, I'm out of touch
 
so basically, in the kernel, there is one unified architecture that all FOSS drivers share, and implement their own hardware-specific bits on top of; in userspace, there are two architectures, one built around Gallium, which supports a wide variety of hardware (with short, but significant, bits of hardware-specific code tacked on), and another that Intel rolled on their own that ONLY works with Intel hardware
also, some random guy decided he wanted to try and write a Gallium driver for Intel's hardware, and got far enough that Sandy Bridge hardware was running quite well, but Intel never adopted it and he eventually abandoned it, so it doesn't work on Ivy Bridge, Haswell, Bay Trail, etc
that driver is called "i915g" and I don't recommend trying it. it was a good idea though
 
"some random guy" ...
 
2:32 PM
yeah, some developer :P
 
a smart guy but not an Intel employee
 
Yeah, that happens a lot ;p
 
even though Intel has quite a few people contributing to the FOSS graphics stack, I think eventually the combined contributions of AMD and Red Hat and VMware are going to make Gallium a simply more featureful architecture, and Intel will have increasing pressure to adopt it.
AMD's driver is already quite good on modern (GCN, even) cards
I think it can run Unigine Heaven
 
Nvidia's linux drivers are great when they work.
 
2:34 PM
and by "AMD's driver" I mean their Gallium-based driver (FOSS)
just to give you a sense, there are maybe 20 people combined between Intel, AMD, VMware and Red Hat working on the FOSS graphics stack full-time or near-full-time, plus 2 or 3 people who are not even employed but just contribute for fun and prestige
AMD and Nvidia EACH employ around 80 people for their Catalyst and Nvidia binary drivers, respectively
and that's a low estimate. it's probably more like 120
 
also? the proprietary blob teams get to start supporting new hardware basically on the same day that the hardware engineer team has decided "OK, we've completed the hardware<->software interface; we'll start implementing the card and maybe look to get first silicon next year"
so the proprietary teams are writing drivers against hardware that's just a fantasy while the FOSS folks are still trying to support 5 year old hardware
I bet AMD's team this year is working on driver bringup for chips that have never been fabricated with a 2017 or 2018 planned release date
testing with a hardware simulator
 
graphics drivers have more engineering effort going into them than even Windows or Office or things like stock market software... there's just an insane amount of complexity there
 
2:39 PM
there was a SLOC comparison somewhere on a blog that said Catalyst has more SLOC than Windows 8.1 :P
it's basically its own operating system
 
they're essentially pocket supercomputers ;p
 
right now the FOSS driver compared to Catalyst is like comparing ReactOS to Windows 8.1
is it the same idea? sure. is it equally as fleshed out? hell no.
 
hm. I need to check on that
 
on what?
 
2:44 PM
oh. what's to check on?
 
It feels like its hardly moved though
 
it sucks
 
;p
it does
 
it has like 2-3 people contributing to it and it isn't improving
 
@allquixotic: they had a drama attack too
 
2:44 PM
at least there's hope for Mesa to eventually become good, as Linux gains adoption, maybe Valve will get involved in driver writing, etc
 
I used to be totally nuts about odd OSes ;p
 
also Mesa is improving at a pretty fast rate, sometimes it improves at a faster rate than the standards bodies can chunk out new standards
@JourneymanGeek now you just lend your ear to OTHER PEOPLE who are nuts about odd OSes, like SmartOS, and go "hmm, that's a good idea :D"
I fail to see any improvement ;p
 
so I had a ROS VM (and a buncha other odd ones. Even got BeOS running at one point)
@allquixotic: I don't consider SmartOS odd tho
It has some ideas I find interesting
 
yeah, SmartOS is a bit different from ReactOS in that it actually does most things well, and doesn't have any huge gaping holes or stability problems
it's based on a production-grade server OS that's very old, and polished
 
2:49 PM
that's why Jonathan I. Schwartz is one of my favorite CEOs of all time, and I really really wish Sun had continued to be a thought leader among big software corps rather than getting bought and strip-mined by Oracle
 
oracle is just plain evil
 
the open source push within Sun was championed by Jonathan
he seems like a really genuine guy and wasn't just CEO to pocket money and buy an island
he had ideals
Jonathan Ian Schwartz (born October 20, 1965) is an American businessman. He is currently President, and Chief Executive Officer of CareZone. Before founding CareZone, Schwartz had a nearly 15 year tenure with Sun Microsystems, culminating in his serving as CEO just prior to and during the company's battle for survival during the American financial crisis, and its subsequent acquisition by Oracle. He was also the founder and Chief Executive Officer of Lighthouse Design, Ltd., a software company focused on Apple's NeXTSTEP platform, which was ultimately acquired by Sun in 1996. == Background... ==
 
lol
I was reading that
 
> As CEO of Sun, Schwartz was known as one of the few Fortune 500 CEO's to use a blog for public communications. He was recognized for his efforts to bring greater transparency into the corporate world, and managed a public exchange with SEC Chairman Christopher Cox about the use of websites and blogs for the dissemination of financial information[6] to meet Regulation Fair Disclosure.[7]

Schwartz generally believed the internet, and Sun's web presence on it, was a far more fair and efficient vehicle for the dissemination of Sun's financial information - as opposed to the expensive, and pr
hard to argue with that
 
@JourneymanGeek Haiku... Haiku...
 
2:53 PM
@Braiam: Yeah, I need to set one of those up again
 
Oracle buying FOSS-friendly Sun just because of a temporary recession is like Luke converting to the Dark Side because his dad cut off his arm
 
haiku is probably the most mature/viable of the oddballs.

Q: Are sharks a threat to undersea cables?

Édouard LopezSlate published an article recently, titled The Global Internet Is Being Attacked by Sharks, Google Confirms. Despite being catchy and all, most of the references seem to be other news outlets or actually contradict the claim. Are there any sources supporting or contradicting that sharks are a t...

 
2:56 PM
@Bob short answer: yup
 
"And since fibre-optic cables generate a stronger electrical field than the copper cables that preceded them, it might be enough to trigger the shark's hunting instinct."
whut?
 
Bob
@JourneymanGeek yea, I was wondering about that too
> fibre-optic cables generate a stronger electrical field than the copper cables that preceded them would you mind providing a source for that? Intuition would have me believe that optical cables don't generate an electrical field. — Bob 30 secs ago
> iPhone 4s has a 3.5-inch Retina display, an 8-megapixel iSight camera with 1080p HD video recording, a FaceTime camera and a long battery life.
Rename all the things!
Translation: "iPhone 4s has a 3.5-inch high-density display, an 8-megapixel camera with 1080p HD video recording, a front-facing (or video-calling) camera and a long battery life."
 
Hmm. Noob programming question. I have a list of pseudorandom numbers. I want to "coalesce" any consecutive numbers into a range of numbers. Ruby supports the Range data type that has a min and max (inclusive); I want to use that. Is the most efficient way to do it, to quicksort the list, then walk through it linearly, then do a "mark" when you find a new non-consecutive number, and keep going as long as the next number is sequential, then stop and "mark" the end of the sequence,
then add that Range to the array of ranges?
e.g. [ 57, 11, 100, 40, 7, 12, 2, 99, 98, 3, 8, 17, 13] would become: [2..3, 7..8, 11..13, 40, 47, 57, 98..100].
 
Good action of the day: Someone from the media department, with purchase desicion power, just asked me if it was better to purchase $11k cameras for recording in high-res or normal $3k cameras that record in a lower res. The goal is exclusively mid-to-low res online streaming.
I think I just saved my institution pockets some $20k
Now it can go to some politician's pockets instead. Yay.

@ThatBrazilianGuy you should at least get a $2 plaque to hang on your wall for being a bom samaritao!

@ThatBrazilianGuy (total guess on "samaritano" but I found google hits on it O_O) (source)
 
@allquixotic: then you find out, its a fried snack ;p
 
@JourneymanGeek mmmm, samaritaos! they sound like crunchy things. do-gooders are always crunchy.
 
3:15 PM
@allquixotic "Fallacy" tottally sounds like something that goes on a salad. I bet they taste great in onlive oil!
 
onlive oil.... the stuff they use to convince people to buy their awful service?
 
(At least in Portuguese. "Falácia" sounds too much like "Alface" (lettuce))
@allquixotic Onlive Oil is just like Snake Oil, but if you spray it on your console it lets you play games.
 
@ThatBrazilianGuy a straw man is a fallacy; if the straw were made out of fresh grass instead of dried, it could make a decent salad with olive oil :)

@allquixotic minnows love grass. it isn't really digestible for humans IIRC (source)
 
3:18 PM
I call my cat a minnow because when she turns her body from head to tail she looks like a fish doing the same
I call my cat all kinds of silly things
few of them make any sense
 
If I ever have a cat I'll name him "Gato". It means "cat".
 
Spanish cognate! also, that's an extremely unimaginative name
 
No, that's just ironic, don't you get it?
OH MY GOD I AM A HIPSTER! O_O
 
I don't think it's ironic
 
Unimaginative is calling a dog "Spot" or something like that.
I've never seen a cat called "Gato". Ever. So I', naming my future cat "Gato".
 
3:24 PM
I had a cat named Spot! after Data's cat on Star Trek: TNG.
how about Meowzie?
;p
 
I once had a cat called Mimi (silly name I picked, but I was 7)
She was the cutest puppy (is puppy only for dogs?)
Anyway, I lived at a small farm back then and when I got home she'd come running in the twilight and I'd see only her eyes sparkling
