Journeyman Geek

I'm not sure where the noise is from

I tried unplugging the audio cord and the cord between the speakers

Q: There appears to be a poltergeist in my speakers (no, really)

I've no idea if there's a suitable Stack Exchange for poltergeists. It appears to be software, hardware or virus related, so I thought I'd try here, seeing as Ghostbusters is just a film, so I can't call them. I'm not going mad, and this isn't a joke. There's what appears to be a radio stream c...

Journeyman Geek

so its not picking up noise from the speakers

Psycogeek

00:09

did you change the general location of the speakers in the residence ?

Journeyman Geek

suspects the internal amp's going dead.

@DragonLord: different issue

Psycogeek

The only thing left (from what you did) would be to get an oscilliscope reading on the power curcuits , pefectlly reasonable thing to do at that point :-)

Journeyman Geek

"I can only hear it when the volume knob is turned down to the min setting "

naw, I should donate the speakers to a museum and buy a new pair ;p

Psycogeek

it is the automated back-beat bass line designed to improve music , especially great when playing hip-hop

@Hennes superuser.com/a/942350/98855 which just leaves one problem, he has 2X VGA and most cards supplying a seperate VGA port on the card do not supply a 2nd one at a DVI port. Most of the cards have only 1 VGA method existing. (even though he said the DVI was DVI-I)

Journeyman Geek

00:44

Yup

I am sure they would tell you at HiFinutcase.com that you simply need new carbon nanotube wiring with diamond conductors and that sound your hearing would go away.

Q: Cannot Remove Password on Windows 10 Account

I am having an issue with removing a password from my account on Windows 10. The account is currently password protected, but I do not want it to be. To resolve this, I attempted to use the "Settings" app, but doing so resulted in the following error. As this is my personal computer and I am a...

passwords windows-10-preview

I do not get this on 2 points.

1) right now i have a password for my account, and never have to enter it

2) if a windows account does not have a password, AND you have all that STUFF on that is designed to let other people , or even yourself, get into your computer. isnt that a very insecure thing to do?

"As this is my personal computer and I am administrator, I have full access " Yea and it sounds to me if the thing is connected to the web so too does the rest of the planet :-)

at least it is not that evil XP out there threatening the whole web from extintion :-)

Anyone updating to Windows 10 on launch day ?

Journeyman Geek

03:23

I will, most likely

DragonLord

I can get my laptop to discharge its battery at nearly 2C by putting both the CPU and GPU under max load (and the GPU already throttles heavily)

Journeyman Geek

o0

DragonLord

...and guess what? My laptop just shut itself down hard.

Looks like I tripped the overload protection on the battery.

System's up and running again.

Journeyman Geek

heh

Its picking up noise from the AP

Cool

A: Why are my games slower on battery power, even with the power plan set to High Performance?

Running a high-performance GPU at full speed while on battery can damage the battery or require more power than the battery can safely supply High-performance mobile GPUs can require significant amounts of power to operate at full speed. The GTX 765M requires 75 W, while top-of-the-line mobile ...

Just pulled the battery out of my laptop, and it's very hot

Not quite out-of-spec hot, but still very hot.

...and I guess I was right. The battery will get overloaded if the GPU wasn't throttled.

I basically just validated my own answer.

(It's on AC right now, of course.)

Psycogeek

03:39

They have sold laptops that the AC power converter itself is not enough power for full load of the laptop. with those people noticed that removing the battery was just as bad as the others have it removing the ac :-)

(the converter and any internal curcuitry stuff too i assume)

That is why I do not really see a big problem in my laptop comming in a breifcase sized container, with added cooling, a supurb keyboard, nice speakers, and a big fat battery :-)

And extra padding , soes i can drop it a few times.

The speakers were picking up a signal from my router

Moved it and no more involuntary dubstep

Psycogeek

5 hours ago, by Psycogeek

did you change the general location of the speakers in the residence ?

So now we KNOW what a router interferance sound sounds like, such valuble information. as we already know what a cell phone would sounds like

HackToHell

05:33

@JourneymanGeek Nice :P

Journeyman Geek

@Psycogeek I did not. I added a monitor, VESA mounted the brix, and moved the router closer

Now I moved the router back to its older place and got a longer ethernet cable for the brix ;p

Psycogeek

oh well i was indicating to move the speakers location to test , which might have also included getting it away from a cell phone :-)

But I didnt say cell phone, because i am sure you already knew about those :-)

Not the same as these problems are also reported at amazon 1-star reviews, but kinda funny , cause we were just talking about . . .

Hi all

I guess no one is in...

Journeyman Geek

Were this IRC, I'd change my name to no one ;p

Dave

ha ha, hello Mr Journeyman :)

Journeyman Geek

I was updating an old answer, and posting a new question/answer on what I learnt from it ;p

Dave

:)

Do you know much / or a little about Firewalls? I'm trying to connect to my SQL server on a remote server. If I disable remote firewall, it works. With it enabled, I can't connect. I've added ports 1433 and 1434 but totally lost what else I can do :(

Journeyman Geek

Are you sure they are the correct ports?

What's the exact error?

is it open the 'right' way? Some firewalls have seperate ingoing and outgoing filters.

( Despite my best efforts, and resizing, somewhere, someone's 56K connection is going to catch fire superuser.com/questions/942469/…)

Dave

09:26

Yes, for testing, I'm adding the ports to both incoming and outgoing ... Yes, they are correct, I'm assuming there are 'other' ports I don't know of though despite reading countless documents/articles

Journeyman Geek

what sort of SQL?

Could you ... er...

check the logs for the firewall?

Dave

I didn't check logs yet... MS SQL Express

Never had this issue before, done many insatllations before... Bloody computers

Journeyman Geek

If something is being blocked, it should be logged, and you can open it

Dave

I didn't want to get into IT. I wanted to be an archaeologist but my parents said I'd only end IN RUINS (he he he he)

Journeyman Geek

Also, with mysql you needed to explicitly allow an external computer to connect

Dave

family friend's computer. complains about too slow.

no prizes for guessing the issue

@Psycogeek I have no idea what most cards do, I just got one AMD card. But if the OP supplied wrong info then he or she has an inperfect answer.

Journeyman Geek

@Bob: they forgot to feed the hamster?

@JourneymanGeek it's an old slim desktop/media centre thingy

Journeyman Geek

hm. The hamster died of old age?

Bob

Journeyman Geek

09:52

(that is to say, it runs XP)

Meh. I have a 230 ;p

Bob

@JourneymanGeek that too

when he first started it, it took ~10 mins

and loaded up "RegCure Pro"

I knew I was in for fun

Journeyman Geek

lol

Bob

It's freakin' 300MB

and "SlimCleaner Plus"

and "Vtools Toolbar"

And "Fire Type Assistant"

and "File Association Helper"

not to mention AVG + McAfee + god knows what else

@JourneymanGeek The hamster drowned in crap ages ago

Psycogeek

Well when your computer is acting slow it is important to install a bunch of crap from the web that says it will fix that, especially things found in the first SEO of the search you do for it.

Bob

I think he just got tricked by all those fake antivirus ads

older man

Dave

10:38

Should older people be destroyed

I'm not talking about doing it in a bad way

but if we could convince them they needed bogus AV software

it should be easy to convince them that learning to swim is really on an 'extra' and not a requirement

Yup. Here's your complimentary handbasket.

Hehm this one made me smile:

Bob

@Hennes That took a rather quick turn.

And what's with the tail o.O

Journeyman Geek

She's a snake lady? What are ya, speciesist? ;p

@Hennes: source?

So... the shared pc has a nicer, bigger monitor, with HDMI and stuff than mine, everything but VGA out is borked on that PC. No one uses it anyway. Kinda tempted to swap my 20" with that....

WHY DID I NOT THINK OF THIS BEFORE.

Bob

o.O

Journeyman Geek

Not sure if I have the desk space tho

Hennes

11:21

Source is "does not play well with others"

Journeyman Geek

OH

The errant story dude!

Nick

12:20

@Hennes What does one usually use to pick the neighbours lock?

Hennes

0000?

1234?

Nick

@Hennes ... Um, I meant something that executes automated bruteforce. lol :D

Hennes

WPS. :)

Actually, no idea. I just guess peoples passwords.

Bob

@Nick Aircrack?

Excepting a rather poor password, it won't do much on a WPA2 AES AP with WPS disabled.

Hm. $45 for a 60GB SSD.

That would make a nice cache for an older system.

Or even a primary drive if not much space is needed.

Nick

@Bob Nice. Too bad I have no neighbours with wifi.

@Bob 0.75$/GB sounds cool. What's the lowest you've seen that figure go? IRL, the best things I get off the street are about 0.5 $/GB but that's only SD cards

Bob

12:41

@Nick Hm... can't remember now.

You generally get better $/GB as you get higher capacities.

(And also higher speeds and more spare flash.)

The real advantage here isn't $/GB, but just purely the low actual price.

@Nick Apart from the massive legal and moral issues, it's also generally not very reliable, if you can do it at all.

Nick

@Bob Ah, true :D

@Bob Still an interesting field to dabble in. Um, ethically, ofcourse.

Journeyman Geek

14:17

(24 inches full HD on some boxen, 27 inches ;p)

Hennes

IIRC cracking WPA2 takes about half an hour and costs $70-ish in amazon time.
(spinning up 4 huge instances with GPU's)

Bob

@Hennes Not if you have decent password.

You're basically reduced to a(n offline) brute-force.

Hennes

I think my own password is reasonaly reliable

Many others are not though, or are even admin/admin

Journeyman Geek

Meh, if you want my home wifi password, just ask ;p

If you want my old school one, go check the notice board...

Bob

@Hennes Apparently WPA2 PSKs are hashed with PBKDF2.

SSID used as salt, 4096 iterations typical.

A tad on the low side but still quite strong with a reasonable password.

10+ chars. Longer even better.

(Also means a random/unique SSID is good)

@Hennes 8x Titan X gets ~2233 kh/s: hashcat.net/oclhashcat

Journeyman Geek

14:32

I thought AMD was better at those things?

also... 8x? 0_0

Hennes

8 of them, or on PCI-e with 8 lanes?

Bob

@JourneymanGeek I thought so too, though that might be previous gen.

Hennes

Not that it would suffer from lack of bandwidth

Bob

@Hennes 8 of them, probably.

Considering they mention 1x GTX 580.

Pretty sure that won't run properly on PCIe 1x.

Hennes

Not sure.

I think that x1 bandwdth is still plenty. But latency is also involved

Bob

14:35

@Hennes I definitely don't know of any cards designed like that.

It's highly unlikely that it means PCIe lanes.

That would be useless information anyway.

It would also imply the Titan X is 60x better at SHA1 hashes than a GTX 580. Unlikely.

7.5x faster is far more reasonable.

@Hennes Anyway, basically, that means an average 1000 years to crack a full-lowercase 10 char password.

Not gonna happen.

Hennes

Uhm, all of them.

Any PCI-e card should work in an x1, x4, x8 or x16 slot

If it does not fit, file out the slot on the motherboard

Bob

@Hennes Should work, maybe. Designed to use 1x by default? Very few, and not on the higher end.

Hennes

And it should just work

Agreed.

Bob

@Hennes If you need to physically modify your hardware, then that is not how it's designed.

It works by spec. But the cards are not physically designed with that purpose in mind.

Hennes

Ok, an electrical x4 slot in a physical x16 connector (plenty of x4 and x8 in serverboards with x16 connectors)

Bob

14:39

And I also see no reason to use 1x on a machine dedicated for hashing with a single card.

@Hennes Yea, seen that. But never seen 1x.

Hennes

Not with a single card, unless you need to faster slot for otehr things

Bob

Normally you just add a CPU by the time you get to that point.

Hennes

E.g. fruit sorting with the cheap commercial graphics card in a x1 slot, and a high end frame grabber in the x16 slot. (the graphics card is just there do debug, or change settings. Usually the monitor is turned off)

Bob

Anyway, it's almost certain that they mean 8 Titan X cards.

Going by the relative performance if nothing else.

@Hennes Whoops, sorry. I mean 1 year average.

(Dropped a factor of 1000 somewhere -_-)

Still, 1 year with 8x Titan X is still a ridiculous amount of time/power to crack one WPA2 password.

And that's with 10 chars.

Easy to make the password longer since you only rarely need to enter it.

And it can be 100% random.

Bob

15:09

@JourneymanGeek I went and edited your answer (and tags on Q) :P

An animation is a fine aid, but isn't really great by itself.

Journeyman Geek

ahh, thanks ;p

Bob

Annoying if you miss some part and have to rewatch the whole thing.

Journeyman Geek

Yeah, even if that's what the question is about ;p

That's a funny one

Someone complained in an answer that licecap didn't work right at high dpi. I started editing my answer and realised it should be a standalone QA

Bob

@JourneymanGeek I haven't needed it on my laptop yet but I'll do that if it ever happens :P

Though, I'm currently looking for an alternative.

LICEcap is simple, but it's not particularly good.

Journeyman Geek

lol

Where does it fall short?

Bob

15:19

@JourneymanGeek It's too simple for some of my desired uses :P

(I'd like a library. I'd also like some minor editing.)

Journeyman Geek

ahh, ok

editing would be nice

Good morning. Would anyone be willing to help me through a Linux install? It's on a house. I have no DVD-Rs in the house, and the livecds I've downloaded for Ubuntu don't seem to fit on a standard CD-R. I do have a Knoppix DVD I'd burned before, but it seems to come up in German...

Or would this be the wrong place to ask?

HackToHell

You can write that to a pendrive and boot from it

Sean Duggan

Ah. I see that there is an SE specifically for Linux.

HackToHell

It's on topic here @SeanDuggan
