This is weird.

I have a windows machine, NTFS drive C:. "my computer" says 40GB free of 465 (so 425GB in use).

WinDirStat says 335GB used.

So either there's 90GB of stuff that windirstat can't see, or something is wrong with the filesystem's free space accounting.

Bob

@ToxicFrog Could be wonky hardlink counting but that usually goes in the other direction.

Hm. I wonder if windirstat correctly reports on-disk sizes?

ToxicFrog

...that's a good question. I don't know if it's reporting disk size or apparent size.

Looks like it's reporting apparent size.

90GB of space leakage still seems pretty high, even with 4K blocks, but it's possible.

Bob

@ToxicFrog Quick test: rather than checking the drive, select everything (show hidden/system) inside the drive root and check the size on that.

via Explorer

ToxicFrog

I'll just install ncdu and use that, it can do either

ncdu reports a difference of about 1GB between disk and apparent size, which works out to about 1K of leakage per file, which sounds plausible.

Of course, there are some directories I can't access, even as root. Who knows what's in there.

Bob

1:12 AM

@ToxicFrog Eh. psexec -s -i

Administrator is not root. SYSTEM is.

ToxicFrog

As Administrator, then.

Bob

while ($true) {
    $dir = [math]::truncate($i / 10000);
    mkdir -force $dir > $null;
    echo $null > $dir/$i;
    $i += 1;
}

when one needs a quick script :) (hi @BenN)

1:28 AM

Hi!

Bob

@ToxicFrog I think I found your discrepancy :P

lotsa small files

ToxicFrog

There's a total of 950k visible files; even if each one wasted an entire disk block that wouldn't account for a 90GB discrepancy.

Bob

Hm.

@ToxicFrog Have you tried running windirstat as SYSTEM?

AMD Radeon RX Vega announced: anandtech.com/show/11680/…

Products available August 14.

This is more than a paper launch - AMD has released final product specifications and pricing.

As rumored and teased earlier, there are two versions of the fully-enabled RX Vega 64, an air-cooled model ($499) and a liquid-cooled model ($699) with higher performance. There's also a less expensive RX Vega 56, with 1/8 of the NCUs disabled and lower clocks on both the shader cores and memory. All cards feature 8 GB of HBM2.

allquixotic

@bwDraco hah, they're beating Apple to the punch! I thought Apple was going to be their launch customer

bwDraco

RX Vega 64 slightly outperforms GTX 1080 in preliminary benchmarks.

Sadly, AMD is doing very high TBPs. The standard RX Vega 64 card is rated at 295W. (GTX 1080 has a TBP of 180W.)

(TBP = total board power)

allquixotic

2:54 AM

pretty ridiculous how inefficient they have to be just to beat a 1080

bwDraco

As has been the case for Radeon cards for a while, the new Vega cards have FP64 at 1/16 of FP32. (For comparison, Pascal other than the HPC/AI-oriented GP100 runs FP64 at 1/32 of FP32.)

allquixotic

but then they're still doing bulk fab and Nvidia is still doing SOI, AFAIR

bwDraco

Lower cost on the GPU die, but I suspect AMD is running on narrower margins than NVIDIA because of the expensive HBM2.

HBM2 is very, very difficult to manufacture.

allquixotic

@bwDraco Vega should be amazing for Ethereum.... :P Pascal's weakness has been in memory performance, as evidenced by the fact that the RX 580, half the card that the 1080 is, can churn out just as many if not more MH/s

I'm sure the Ethereum miners are salivating over buying out all the stock of Vega the instant it goes on sale

bwDraco

They're probably getting good economies of scale, but there's no getting around the cost of making HBM2.

Vega 64 actually has the same memory bandwidth as GTX 1080 Ti. I suspect it has lower latency, though.

A business to run, sigh...

PC Gamer notes that Vega's high power consumption will make it less attractive to cryptocurrency miners. pcgamer.com/…

Also, AMD has introduced gamer-focused Vega Packs that pair cards with AMD system components and games in an attempt to control demand from miners.

I do not know if I really want Vega, though. My heart's pretty much set on the GTX 1080 or GTX 1080 Ti, though I'm still kinda resentful of NVIDIA for creating vendor lock-in with their PhysX and GameWorks middleware and prohibiting manufacturers from supporting both G-SYNC and FreeSync on the same display.

Bob

3:06 AM

@bwDraco depends on the MH/W too

double the power consumption, but if it can more than double the MH rate then it's still viable

bwDraco

@Bob Rapid packed math.

That might make a huge difference.

Bob

disappointing to see a return to huge power consumption though :\

there goes me giving advice to not worry high-power PSUs :(

(I was saying any modern GPU should be fine on a 400W PSU)

bwDraco

Currently, Astaroth is specified to use an 850W PSU. I'd rather not have to step up to 1000W, and I shouldn't have to.

Bob

@bwDraco lol. it won't make that much difference

100 for CPU, let's call it 300 for GPU, 100-200 for other components

600 would still do fine

bwDraco

(that would add $70 to the BOM)

Bob

3:09 AM

800 is still overkill

1000 is massive overkill

bwDraco

Worst-case power consumption with components overclocked is probably in the ballpark of 550-600W, judging from what PCPartPicker is saying.

(434W estimated load power consumption, plus about 50W from the CPU and 75W from the GPU when overclocked)

Bob

@bwDraco so my guess wasn't far off :P

put it this way. i7-7700k, GTX 1080, many HDDs... I barely go above 300W (IIRC) total system draw and even then it's by a little

a 75W overclock is massive btw

bwDraco

I'd probably say normal gaming load power consumption is in the range of 250-300W. AotS would probably cause the system to pull closer to 450W without overclocks.

Bob

swap out the GPU for one with 2x the consumption and 500W would be on the high end

@bwDraco I think I did my tests with a furmark load on CPU and GPU

bwDraco

Prime95 and FurMark are the usual torture-testing tools.

Bob

3:14 AM

@bwDraco furmark has a CPU stress tester too iirc

can't remember. it was last year

unless you plan to go multi-GPU there's not much point in anything higher than 600W, anyway

anything higher would be for other features (fan-off under a certain load, maybe some features are only available on higher tiers, etc.)

this is, of course, assuming the PSU can handle its max rated power all on the 12V rail(s)

bwDraco

@Bob Let's not forget that I'm trying to use the very best parts out there. The plans call for Seasonic PRIME Titanium.

Bob

@bwDraco eh, for similar reasons I went with an 860i

just saying. the point isn't because it's 800W; it's the other features

bwDraco

I believe the AX860i is slightly less expensive than the PRIME...

...seems not.

Newegg has the price set at $209.99, $10 more than the PRIME Titanium 850W.

A key principle behind Astaroth is reliability. I don't want to skimp on anything I can't easily replace.

Allenph

I need an educated opinion. I'm just a software engineer. I run a RPi3 cluster at home. It's connected to the internet via DDNS. I have a crappy old Netgear N300 flashed with DDWRT handling the routing. I'm looking for something a little more substantial.

I use the router as a bridge between my stock ISP router and my server cluster. (Both run DHCP.) The bridge connects to the ISP's router over WiFi and then acts as an AP for my wireless RPi3s. I need a more modern router (I intend on flashing DDWRT) because I want more speed, and I want to isolate some server services by serving most of m…

bwDraco

@Allenph WRT1900ACS?

Bob

3:21 AM

@Allenph Some would suggest OpenWRT these days. There's also nice x86 boards you can run pfSense on.

Allenph

@bwDraco THrowback to WRT54G?

Bob

Apart from that... Asus is solid. TP-LINK is good while cheap.

The more enterprisey equipment is better supported (think Ubiquiti) but you won't be running custom firmware on those.

Allenph

@Bob OpenWRT over DDWRT? I thought DDWRT was the standard.

Bob

@Allenph There is no "standard", but ddwrt dev is very haphazard these days :\

bwDraco

@Allenph Kinda, but despite efforts by Linksys, development of open-source firmware has been problematic due to chipset vendors being very reluctant to release code for their chips.

Allenph

3:23 AM

@Bob Part of the goal is to do this all open-source. (Software at least...the RPI3 will finally remove non-free components in the GPU bootloader in Stretch)

Bob

@Allenph Then pfSense on x86 is probably your best bet.

It's probably a bit harder.

But it's more open.

bwDraco

Linksys wants these routers to be able to run open-source firmware, but it seems Marvell et al. aren't playing ball.

Bob

As long as you're running (dd|open)wrt, you're somewhat at the mercy of esoteric hardware and running software not supported by the manufacturer.

x86 is a well understood platform

But if you want easy or cheap, then... yea, one of the wrt's.

Allenph

Yeah...I don't want to spend more than $50 honestly.

Bob

I'm still on ddwrt but it's been upgrade hell. @CircusCat prefers openwrt iirc

Allenph

3:25 AM

I feel like I should get more than enough power out of that.

bwDraco

I think they sorted out the chipset issues, though.

Bob

@Allenph ...$50 doesn't get you much :P

Allenph

@Bob The RPI3s only use 2.4 at a max speed of like 100mbps or something like that.

bwDraco

@Allenph A decent router will cost you at least $150. We paid $230 for our Nighthawk X4S.

Bob

and don't start with the rpi3, which has, frankly, terrible performance for any real workload

@Allenph if you really want cheap, pick up one of the basic TP-LINK things, flash it, and be done with it

don't expect much out of it

bwDraco

3:27 AM

I'm not really an open-source purist. I choose the solutions that best fit my needs.

Allenph

@Bob I started with the ODROID. I should have stayed...but.

I'm running a web server, an email server, and a DLNA server for LAN.

Not too heavy.

bwDraco

If open-source best meets these requirements, then I'll go with the open-source solution. If not, I'll pick something else.

Allenph

Especially spread over three Pis.

Bob

@Allenph frankly, I dislike most ARM boards

bwDraco

@Allenph What level of openness do you need?

Bob

3:28 AM

(and that's after using a rpi, and playing with a thunderx server)

they work for some things, but can be pretty damn finicky

*shrug*

Allenph

Side note...there's never going to be a way for me to play nice with my ISPs router if I want hairpinning, is there? IE...connected to ISP's router...try and hit my domain...request filtered to my other router?

Bob

I'm sure someone makes a pfSense-capable ARM board

bwDraco

Is it completely open with no closed components whatsoever, or can a few binary blobs be tolerated?

Bob

but, honestly? you're not getting it for $50

bwDraco

If you're looking for a 100% purely open solution, your options are extremely limited.

Allenph

3:30 AM

@bwDraco The RPi3 has some non-free components. I mean...you have to be pragmatic at some point.

bwDraco

6 mins ago, by Allenph

@Bob Part of the goal is to do this all open-source. (Software at least...the RPI3 will finally remove non-free components in the GPU bootloader in Stretch)

Bob

@Allenph you can probably fiddle with static routes and hairpinning on a NAT layer before hitting the ISP router

bwDraco

@Allenph Blah. I don't subscribe to the ideological theory that all software must be free.

(let's not get into the free software/open-source software debate here)

Bob

@Allenph if you want to stick with ddwrt, look up supported TP-link models on the ddwrt wiki and buy one you're happy with

Allenph

@bwDraco I don't either.

Bob

3:31 AM

you have maybe 3 or 4 models to choose from under the $50 mark

Allenph

I think there is a space for paid software. Even proprietary.

Bob

I think maybe one supported 802.11ac

Allenph

@Bob My problem with DDWRT is that they SAY they support it but fail to mention that model doesn not support OpenVPN, etc.

Bob

tbh more recently I've been trying to separate my APs from my routers

Allenph

I understand it's very difficult, but.

Bob

3:33 AM

custom firmware works fine for routing. it tends to suck for wlan

bwDraco

I realize that a 100% open solution eliminates any potential security concerns due to hidden vulnerabilities or (worse, although unlikely) backdoors that cannot be easily detected.

Bob

@Allenph and that is why I suggested x86 with pfSense

Allenph

@Bob Maybe another RPi3 doing the routing and the VPN and just using the router as a bridge?

bwDraco

Why not just x86?

Consider getting a Compute Stick.

Bob

@Allenph that could work. personally not a fan cause it's a single slow (100mbit) port, but I've done it in the past

Allenph

3:34 AM

@bwDraco Honestly...because I'm a little OCD and can barely tolerate the router not fitting on my nice neat wireless "server rack."

Bob

@bwDraco a compute stick is possibly just as bad as a single-board ARM machine

you're not getting much connectivity out of it

bwDraco

@Bob The application is extremely cost-sensitive.

x86 is not cheap. The Compute Stick is the cheapest solution I could suggest.

Allenph

At that point I might as well get two wireless radios and use the Rpi3 itself as the bridge, yeah?

bwDraco

I'm not sure what to suggest at this point.

Even though I'm the one responsible for managing the network at home for my parents, I don't want a solution that requires too much maintenance.

Bob

@Allenph remind me why you can't run openvpn with ddwrt?

was it the lack of flash?

Allenph

3:41 AM

@Bob The particular router I have has a weird partition scheme apparently. The flash is effectively limited to 3.8ish MB.

So I picked the newest build that fit.

Bob

> OpenVPN is only available on units with at least 8mb flash

bleh.

bwDraco

Back to the Radeon Vega discussion: The Vega 10 die is huge, larger than even Pascal GP102, with 12.5 billion transistors over 486 mm2. A big reason for this is the large amount of SRAM on the chip. tomshardware.com/news/…

Allenph

It supports PPTP.

But that's obviously not secure.

Anyways...thanks guys! Appreciate it!

Bob

@Allenph See if you can get your hands on a WR842ND

that one has 8 MB flash

A WDR3500 could also work

and supported by openwrt => wiki.openwrt.org/toh/tp-link/archer-c50

Allenph

@Bob I think I'll look at that last one. If worst comes to worse...I could probably install whatever I want on the USB with JFFS.

Bob

but maybe not ddwrt

@Allenph take a look at the C50

bwDraco

(Ryzen Threadripper 1900X: 8C/16T Whitehaven (Zen) @ 3.8-4.0 GHz, 16 MB L3$, 4 MB L2$. 180W TDP, $549.)

XFR on Threadripper has been revealed to be +200 MHz on all chips thus far.

Allenph

I'll take a look. Thanks @Bob.

bwDraco

So much exciting AMD news \o/

Preorders for Ryzen Threadripper 1950X and 1920X open tomorrow and will ship on August 10.

Now... one of those things I like about Threadripper is how they're hitting fairly high clocks with all cores under load. 3.4 GHz over 16 cores is quite remarkable.

so... it basically a cut down, full fat server processor?

cause I remember oldschool server processors had heatsinks held down by screws

bwDraco

@JourneymanGeek Yeah - but with two Zeppelin dies (and two blanks for IHS structural integrity) instead of four.

May 30 at 15:13, by bwDraco

Well, well. The SP3 socket is going to be tricky to work with. The cover is secured with Torx screws. Then again, it was originally designed for server processors...

(TR4 is a close relative of the server SP3 socket)

Journeyman Geek

the multi die packages are not

Bob

7:01 AM

@Allenph You'll want to note that ddwrt doesn't seem to list C50 support.

OpenWRT does but it seems to need a TFTP flash, not a webui flash.

Though it is a cheap way to get 8 MB flash

Hello people

I've been dared to get pink braces

I have three minutes to decide before the orthodontist calls me in.

Should I do it?

It'll be for a month

DavidPostill

@Rahul2001 lol by whom?

It sounds a bit "gay"

Rahul2001

@DavidPostill semi-girlfriend/best friend

Not so much girlfriend tbh anymore

@DavidPostill hm. What does that mean, exactly?

DavidPostill

@Rahul2001 Erm without offense to anybody "gay" is an expression that can mean "homosexual"

Rahul2001

@DavidPostill ah yeah well

Oliver Salzburg

@Rahul2001 Don't

Rahul2001

10:13 AM

Colors shouldn't be related to homosexualitiy :/

@OliverSalzburg lol why not?

I might just get purple instead, darker colour look better

Oliver Salzburg

@Rahul2001 If you like pink, go for it. If a girl "dared" you to do it, don't

Rahul2001

@OliverSalzburg well, too many people are looking forward to it

And I don't have anything against the color

So eh

Oliver Salzburg

This is the way in which girls test if you have a spine or if they can shape you to their will

Rahul2001

Lol the teacher overheard us and she just said "you'll look cute" ;p

Oliver Salzburg

You also don't let a girl give you a makeover, paint your nails or cut your hair

Rahul2001

10:15 AM

We have a very weird teacher

@OliverSalzburg ah yeah well. Fair enough.

djsmiley2k

hmmm

I used to paint my own nails at 6th form

but thiungs are different here... so

Rahul2001

@OliverSalzburg yeah seen that in the past. But I've known this girl for a long time, she knows what she can ask me to do and what I will refuse.

Oliver Salzburg

@Rahul2001 You're right, it shouldn't be. But we all live in our own little societies and cultures. And while it is still associated by people in a way that they possibly will make fun of you, it's best not to try to be a pink rebel

@Rahul2001 I'm exaggerating, but there is truth to what I said. How much, you will learn later in life :P

Rahul2001

@OliverSalzburg lol okay :)

@djsmiley2k guys don't usually paint their nails here. Isn't seen as "masculine"

Oliver Salzburg

When I was younger I let girls pull that shit on me several times and I always regretted it. I always thought it would get me "in" with them, it didn't. It just friendzoned me. Of course, your mileage may vary, but be careful not to be dragged into stuff you might later regret just to get your hands on a girl

Now I really want to know what that $75 S8 clone is like :\

Wish I could get an Audi S8 clone for that price

@Rahul2001 that was the point of doing it.

I never had a chance wit hthose girls

so friendzone was fine

it gave me friends xD

it did however get the attention of some other girls, whom I've spoken about b efore

10:58 AM

@OliverSalzburg lol do I want to know you're going?

you know, with that and "shape you to their will"

Oliver Salzburg

@Avery I gave more details later on :D

Avery

to be fair, pink braces can be passed off as "oh I got them to match the color of the skin (or whatever the parts inside mouth are called)"

Oliver Salzburg

You either want them or you don't. If someone else "dares" you to, then it's not what you want

If you want to do what they want, then there should be some incentive. But I propose that it is not worth it

Avery

@OliverSalzburg yeah that ended up like the other possibility apparently. Still "friendzone" is a bad statement, because while you don't end up with a partner, you end up with a close friend, which is probably acceptable for many once they realize the rarity and importance of that.

Oliver Salzburg

In the end though, nothing is more valuable than your own experience :D

Journeyman Geek

11:02 AM

@Avery gums?

Oliver Salzburg

@Avery I agree that a good friendship is a nice thing to have. But not when you intended a romantic relationship. In that case, it will hold you back emotionally

well, I was 16

it was march

so 16 and 3 monthsish

@djsmiley2k it might have 2 sides, but not 2 halves, no.

Oliver Salzburg

Given how much your character can develop between 15 and 30, I would consider it very rare that you can stand the same people around you

djsmiley2k

two ways to go

@OliverSalzburg indeed

There's very few people I can stand, full stop xD

Oliver Salzburg

When I was 15, it was enough to share the same taste in music to start a relationship

Today there are 1 person in 1 million who even share the same taste in music that I have

don't forget if you have the right squishy bits that they are interested in!

thats a big thing these days

Oliver Salzburg

11:41 AM

Good point

djsmiley2k

lol

Avery

let's be honest, that was always a concern, not just lately.

Burgi

its more out in the open these days

Oliver Salzburg

At least it's not something that can easily catch you by surprise

Well, not in my experience anyway

Burgi

hm...

Oliver Salzburg

11:44 AM

Political views can catch you by surprise

Burgi

speaking of politics... its 100 years since the passendale offensive today

from what they were saying on the radio it was the grimmest bit of the war

DBAN... obviously disk size affects the speed but are there any other considerations?

Journeyman Geek

what sort of wipe you're doing, rotational speed...

Avery

@Burgi true, and that's kinda fun to argue about

@JourneymanGeek i think i am just doing the basic free one

Journeyman Geek

oh

Burgi

11:50 AM

does CPU make a difference? if i slap the drives in a faster PC will they process faster?

Avery

well, my boyfriend sees the openness unnecessary and shoving-into-face...-ey, I see it as representation and a call for acceptance and clarity. It's fun to have constrictive criticism regarding that topic.

Oliver Salzburg

@Burgi Don't overdo the iterations :P

Burgi

or is it all down to the drive speed?

Journeyman Geek

tbh, not really

Oliver Salzburg

It's mostly drive speed

Journeyman Geek

11:51 AM

its probably all down to (realworld) drive speed
