Bob

00:00

And what size of drive you can afford.

bwDraco

The issue UTF-8's dealing with is high write amplification due to a combination of infrequent TRIM and low free space.

Bob

@MichaelFrank ...uh. Are you my admin?

Michael Frank

So while going through the permissions on network shares to check the standard... I found that most users shares are open to Everyone. o.o

bwDraco

@UTF-8, if you have questions, be sure to let me know.

Michael Frank

@Bob Ha. This is Basic Onboarding 101. How do they not script this kind of thing? :/

Bob

00:02

@MichaelFrank I think I was hired at a bit of a funny time. I have my own OU in AD and all o.O

No one else is in this OU.

Michael Frank

whaaaaaaaaaaat

Ben N

You're special!

Bob

huh. they finally moved me out of it

sometime since I checked last year anyway

Michael Frank

They probably misclicked new OU when trying to click new user and just rolled with it.

Burgi

00:20

came 2nd in the quiz :(

Michael Frank

00:55

Get-WmiObject -Class Win32_Share -ComputerName WH0RCUTEACHER Huh.. That's an interesting computer name.

Michael Frank

01:06

Okay, so on a scale of 1 to buy a new computer, what's the damage here?

Journeyman Geek

Have you tried turning it off and on again?

Michael Frank

It does that by itself.

Journeyman Geek

Backed up?

Michael Frank

Ha

Journeyman Geek

Was about to suggest restoring

That looks software

Hmmmmmm

discussions.apple.com/thread/7687220?start=0&tstart=0

support.apple.com/en-sg/HT204063

Seems painless

Michael Frank

01:29

Hmm... doesn't seem to be doing much, although I'm not sure if I'm doing it right or not. D:

Oh there we go. Looking better. Apparently holding the PRAM reset keys at a random time and not when it says to works better...

Journeyman Geek

01:43

Ah!

Michael Frank

Although it just took me to the recovery menu, which is better than a panic message at this stage.

Progress!

William

howdy

quick question

@JourneymanGeek this questions superuser.com/questions/165216/… answer applies to blurays drives also but it isn't initially obvious.

should I ask a separate question superuser.com/questions/1181433/… or edit that one

Journeyman Geek

I'd go separate. Tho I'd add more details were I asking that

William

like what?

Journeyman Geek

Mention what drive you have, and ask how you would identify if that drive or others supported dual layer Blu ray or DVD burning.

Ohhhhhhhh.

Sorry. Misunderstood.

William

01:53

so delete ?

Journeyman Geek

Comment under the answer that works that it works on bl too.

William

bluray you mean not black?

Journeyman Geek

On a phone. Getting autocucumbered.

William

So should we have 2 questions or 1?

Journeyman Geek

1. Now if it involves dual layer Blu rays....

Michael Frank

02:18

@JourneymanGeek Looks like the NVRAM reset doesn't help.

Journeyman Geek

:(

Michael Frank

Yea, and unfortunately there's no instructions anywhere on what to do if that doesn't work. :|

Bob

02:44

@MichaelFrank Warranty?

Michael Frank

@Bob I don't think it's covered anymore.

Bob

urk

Journeyman Geek

@MichaelFrank time for a question? :p

Michael Frank

@JourneymanGeek Yea, okay. Just don't make me put it on AskDifferent.

Journeyman Geek

Su is fine. I'll also throw in a bounty with aibobot once it's eligible if I remember. Question interests and annoys me

allquixotic

02:56

@MichaelFrank rossmanngroup.com

how old is that MBP?

Michael Frank

Macbook Pro 6,2 by it's model name.

Could be mid 2010?

Journeyman Geek

@allquixotic also, he's in NZ. Shipping costs may be a factor

Michael Frank

Also, I'm not sending this MBP to New York...

allquixotic

well Louis would know who's good at MBP repair in NZ

mid-2010... probably on the very fringe of what they'd be willing to repair

assuming it's hardware, that is

Journeyman Geek

03:11

Hmm. @MichaelFrank that thread suggests clearing the smc too...

Michael Frank

Tried that one as well

They both don't seem to do anything.

Journeyman Geek

Ah

Michael Frank

I can get into Recovery mode, but it's not particularly useful. Although the health check seemed to suggest the HDD was okay.

Michael Frank

03:47

Okay, posted a question.

http://superuser.com/questions/1181453/macos-kernel-panic-at-boot-panic-initpro‌c-exited

Michael Frank

04:01

Bleh... Ran the First Aid again on the partition this time and it came back with an error code 8. Not sure what that is, but it's obviously not great.

Journeyman Geek

04:15

on the contrary

it indicates it might be fixable

No backups?

I have no idea what a recovery environment for an OS X system would be like

(hell, I don't even know if target disk mode is a thing and/or if a standard linux livecd would actually work)

bwDraco

@MichaelFrank Looks like OS corruption to me.

Journeyman Geek

jhmm

@MichaelFrank maybe switch to single user mode and run fsck?

HackToHell

04:32

What's the cheap ass mouse that's comfortable as hell ?

I think it's the logitech one right

Journeyman Geek

Yeah

logitech is my default cheapass mice

HackToHell

@JourneymanGeek What model number do you use

I broketh my old mouse :'(

Bob

@JourneymanGeek hey, not just cheapass!

<== G602 & MX Master

Journeyman Geek

Errrrr

I was running a g300.

It's probably replaced by now.

We also have a m310. Used to be my laptop mouse but I handed it up to dad.

I tend to like bigger mice tho

HackToHell

04:55

Me too, feels good in the hands <3

allquixotic

@HackToHell I have like a $9 Logitech Unifying mouse at work, AAA battery, has never been replaced in like 4 months

works perfectly, and even supports simultaneous connectivity with a solar keyboard on the same unifying receiver

HackToHell

wow nice

allquixotic

OS recognizes it as a standard USB hub with a standard USB keyboard and mouse hooked up to it, so no special drivers needed

HackToHell

Can you link the model number ? Man I can make my entire setup wireless without having to use bluetooth ones then(rather expensive)

Didn't know you could receive both \m/

allquixotic

@HackToHell yeah, a single unifying receiver can handle a fairly impressive number of unifying devices; not sure of the limit but it's gotta be at least 5 or so

logitech.com/en-us/product/wireless-mouse-m325

logitech.com/en-us/product/k750-keyboard

I remember them both being slightly cheaper than those prices; might've been a temporary sale

> 18-month battery life

welp now I know I have to buy a new battery around the end of this year

HackToHell

05:09

Nice, I'll put them on a deal alert website and grab it when it's cheap

allquixotic

good idea :)

they're mass produced items and I imagine worldwide, so you can probably find them on deals often

BTW the solar keyboard battery can stay charged indefinitely (we assume, until the battery dies, so maybe 10 years or more?) without external power of any kind, with the power switched on 24/7, if it just has a regular office overhead light on it during the work day, or even better, natural sunlight (very powerful compared to office lighting)

HackToHell

I'll probably not be getting the solar keyboard, don't mind swapping batteries once a year.

@MichaelFrank Subscribe to Louis Rossmann's Youtube channel. When it says he's livestreaming, post your question in chat. Someone (not even necessarily Louis) might be able to assist in diagnosis.

He has repair techs (lots of them...) watch his livestreams

Bob

06:00

@allquixotic Logitech has insane battery lives on their lower-end products.

The higher end... not so much :\

bwDraco

06:25

The Skylake-S die is 122 mm² in size. At 91W TDP, this is a staggering 745 kW/m² heat flux density.

Overclocked, it would be easy to make this value exceed 1 MW/m².

It's often compared to the surface of the sun.

> The heat flux generated by today's microprocessors is loosely comparable to that on the Sun's surface

@Psycogeek Know these things? weinproducts.com/batteryfree.htm

Rahul2001

What's this I hear? There's something like a 'mid-term' election or something which takes place in two years in the US? I'm confused.

@Bob I can attest to this. My G602 battery used to last for ages.

Bob

@Rahul2001 actually, G602 falls into the higher end range with shorter life :P

Boris_yo

Is it possible to find log in Windows 7 of my actions?

Rahul2001

@Bob Seriously? Eh, I got it cheap here and the battery lasts for months so, eh

Boris_yo

I just deleted something without paying attention. Looks like not only 1 file was selected.

Bob

07:06

@Rahul2001 but that's with two

and still less than half of the lower end ones

Psycogeek

07:19

nope, only thing extra i use in photography is a downstream flash unit, that triggers when it sees the camera flash. i think it is a a vivitar df200.
At first i was worried that it would not be fast enough, but it is.

So when using a compact camera which the flashes only ever make it about 10feet then i can use it either stuck next to the camera itself (making everything flat but filling) , or (better) to put it down the way some and offset from the camera as a key light, and fill. because it is the same as an on camera shoe flash with a big xenon flash, it finishes the job.

once you get into hotshoe triggers and arrays of standing flash units that each one can light up the whole room, that is beyond my skill and budget. You have to keep the batteries on the minion flashes all going, a job in itself, plus pay for the High $$$ ticket of working that way , and nobody actually paying for it :-)

@Boris_yo isnt that what the trashcan is for? I setup my trash to not even ask anymore as long as it isnt a permenent delete. It is sooo easy to recover things from the trash, but it isnt a backup.

once you have deleted it "permement" , it still isnt off the disk yet. so an undelete program will undelete it. Which is really easy unless :-) you used the trashcan which will have renamed it first.

Boris_yo

07:45

@Psycogeek Not if it's SSD...

Psycogeek

sure even SSD, it doesnt have to delete stuff until it is overwiritten either.

although it could have been trimmed and garbage collected ?

SSDs are lazy too :-) oh we will complete that deletion when it is actually needed. we wouldnt want to look slow pausing to overwrite the whole thing now. Course DragonLord would be the one to ask about that.

Boris_yo

@Psycogeek DragonLord is he SSD master?

Psycogeek

oh he be studing up for sure.

Boris_yo

I will recall the spell to summon him...

Psycogeek

just post some spam , wait for it :-)

Boris_yo

07:51

Vita mortis kaa!

That's not spam. That's spell from Icewind Dale.

So if he played the game he should appear.

Psycogeek

OMG my dog just keeled over, What did you DO?

i think you raised demonic spirits , from the netherworlds of doom.

(or some such blather)

Boris_yo

It only works online.

I need conversion adapter for it to work offline. 3D printer could do it.

Psycogeek

Well let me get the dog logged into steam, and we shall see if he will re-spawn

Boris_yo

Actually 4D printer. We entered 4D as of 2012 remember?

Psycogeek

If i remembered 2012 then virtual reality also worked , Nope :-)

must fire up your google cardboard, and use the VR to traverse time. We could start by going back to ??? how far back would Alan Wake be?

Boris_yo

08:02

@Psycogeek Alan Watts?

Psycogeek

yea him too
" In the game, a "darkness" is taking over humans, animals and objects. These enemies, dubbed the "Taken", are murderous shadows that attack Wake, wielding weapons of their own, ranging from mallets and knives to shovels and chainsaws. They vary by speed, size, and the amount of damage they can take, and some can teleport between short distances." https://en.wikipedia.org/wiki/Alan_wake

which is why it is important to have Flash.

or you will be overwelmed by the darkness, or just bad cases of Red-Eye

Boris_yo

@Psycogeek Japanese are good at these things...

Psycogeek

Ok the dog re-spawned ok, but he is really odd shaped, oops that was mine craft, crap, now my dog is only 8 pixels.

but he plays back reallly well on a Intel Gpu now

how is the soldiering going?

Journeyman Geek

Did different<redacted> :p

Doing more <redacted> like we have been doing all week tomorrow.

Burgi

ffs

we've been charged $900 for a service the old digital team set up AND NEVER USED!!!! >>>:(

Journeyman Geek

@Burgi maaaaan

Cancel?

Burgi

i've raised a support ticket

we are cancelling the old credit cards this week so probably next month is when everything goes crazy and breaks

Journeyman Geek

Ah. Interesting times.

Rahul2001

Burgi

thats oddly specific

DavidPostill

@Rahul2001 lol

That reminds me of the infamous Calculator bug.

Burgi

@Rahul2001 you have 0.00999999999999801 coins in india, right? ;)

@DavidPostill what calculator bug?

Rahul2001

@Burgi but... $

DavidPostill

@Burgi You have to ask? Seriously?

Sqrt(4) – 2 != 0

Burgi

in windows calc?

-1.068281969439142e-19

Rahul2001

lol imgur.com/a/jEFC1

DavidPostill

@Burgi Exactly :)

Burgi

is that due to an issue with binary floating point numbers?

DavidPostill

09:26

@Burgi Yep

What Every Computer Scientist Should Know About Floating-Point Arithmetic is the reference to read...

Burgi

there was a serious bug in the original pentiums that had a similar issue but with larger more human numbers

Rahul2001

@DavidPostill I would try it out except that Win10's calc is messed up

DavidPostill

Burgi

confirmed in win10 as well

Rahul2001

Lol, they still haven't fixed it?

DavidPostill

09:34

@Rahul2001 The thing is it's not actually a bug even though everyone claims it is.

Rahul2001

@DavidPostill hm?

Bob

@Burgi No, the FDIV bug was actually a bug. This is correct behaviour, for certain definitions of correct.

Burgi

@Bob incorrect definitions? ;)

DavidPostill

@Rahul2001 Why does the Windows calculator generate tiny errors when calculating the square root of a perfect square?

Bob

@Burgi Eh. It fits the IEEE 754 spec.

FDIV bug was just plain wrong.

Burgi

09:39

i knew about the binary floating point issue but none of my code has ever needed that sort of of maths so i wasn't able to recall it

Pentium FDIV bug

The Pentium FDIV bug was a computer bug that affected the floating point unit (FPU) of the early Intel Pentium processors. Because of the bug, the processor could return incorrect decimal results when dividing a number. Discovered in 1994 by Professor Thomas R. Nicely at Lynchburg College, Intel attributed the error to missing entries in the lookup table used by the floating-point division circuitry. The severity of the FDIV bug is debated. Intel, producer of the affected chip, claims that the common user would experience it once every 27,000 years while IBM, manufacturer of a chip competing with...

DavidPostill

@Bob The IEEE library is no longer used by Windows Calculator :)

Bob

@DavidPostill Hm? It's a spec, not a lib... and no longer used what?

DavidPostill

When you change the insides, nobody notices

> The innards of Calc - the arithmetic engine - was completely thrown away and rewritten from scratch. The standard IEEE floating point library was replaced with an arbitrary-precision arithmetic library. This was done after people kept writing ha-ha articles about how Calc couldn't do decimal arithmetic correctly, that for example computing 10.21 - 10.2 resulted in 0.0100000000000016.

Bob

@DavidPostill Eh. Some funny base-10 float instead?

DavidPostill

@Bob No idea :)

@noitsbecky huh, that's cheap

cheaper than the train lol

@noitsbecky ... does that include the one in the backyard?

Journeyman Geek

@Bob clearly @noitsbecky is already there.

Rahul2001

I manifest extreme disappointment in my family's gross inability to keep the house stocked with chocolate.

Journeyman Geek

goes raid the fridge for the good stuff

Rahul2001

12:12

@JourneymanGeek My fridge has no stuff, let along good stuff :(

Right, so, I'm going to ask her out tomorrow, and this is not going to be easy...

UTF-8

@bwDraco @Bob i'm sorry, i didn't have access to the internet any more, yesterday, and today not until 12:00 UTC (20 minutes ago) because DSL wouldn't sync. i only have 1 extended partition and in that 1 logical partition (which is formatted as ext4). this partition has the standard space space of 5%, afaik. so that's 12.8 GB of guaranteed free space. i additionally keep 25 to 35 GB of user-usable space free, so that's about 43 GB (+/- 5 GB) of free space without ssd-internal spare space

@bwDraco @Bob should i maybe try to compact the data on my disk?

Bob

WELP

UTF-8

my home folder is encrypted, btw. the rest of the disk isn't

Journeyman Geek

@Bob is this one of the new drives? 0_0

UTF-8

oh, shit. your drive isn't exactly well-off either

Bob

12:25

@JourneymanGeek nah, one of my original internal ones

it used to be in RAID... whoops

~mid-2011

Journeyman Geek

ah

Boris_yo

Who has Apple device and iTunes installed?

Bob

wellllllllllllllll then. CDI won't even give me SMART info

Journeyman Geek

0_0

try something else?

Bob

you know. I think the worst part is I can't remember what I was using this drive for

It's probably backed up ... but nfi where

oh here it comes

it ded

hm actually

I can still read the drive

so... SMART failed but not the drive itself? o.O

@JourneymanGeek I think I have my own DOID now :P

Journeyman Geek

12:28

Yeah

that can happen

You should backup the data ASAP

and test the drive

Psycogeek

SMART , isnt.

Journeyman Geek

If you can read off it, unstoppable copier is a good choice

@Psycogeek smart is working as it should

Bob

@JourneymanGeek looks like it's mostly throwaway data. well, 90% of it I already have another copy of. The other 10% is just video editing scratch, and a couple MSDN ISOs I can redownload.

Journeyman Geek

ah

hm. gsmartctrl and short and long tests?

Bob

The bigger problem is my "other copy of" is now the only copy

Journeyman Geek

12:29

Time to back that up

Bob

ayup

it's 2 TB of data -_-

this'll take a while

Psycogeek

@Bob where is the beef? The raw data?

Bob

I'm just gonna throw Windows Explorer at it and see how that goes

ahhhhh that was my share drive

of course!

hmmm. proooobably not a good sign that copy speed is fluctuating between 0 and 10 MB/s

on a drive that should handle 100 MB/s consistently

@JourneymanGeek best part? I haven't used this drive (read or write) in months... it's just been sitting there, spinning :P

think the Nvidia update reboot killed it

which does make me mildly concerned because its brother is my main backup drive

...time to copy those too, I suppose

Psycogeek

ahh it is just mis-aligned :-) did you remove them bits from the drive before removing it from the raid?

Boris_yo

@Bob Does it show which parameter is under/outside of accepted threshold value?

Bob

12:35

@Boris_yo It should, but it doesn't, which is kinda the problem here.

Psycogeek

as if . . . it wasnt reading the smart data at all, or properly?

Bob

@JourneymanGeek I think problem is I don't know when my last backup was. Or what was added since. Whoops.

Would've been before Acronis, since I haven't touched this in a while... bleh.

Hm. Maybe worth tossing ddrescue at it...

nah, too much trouble

Psycogeek

Journeyman Geek

@Bob I like roadkil's unstoppable copier for things like this

Bob

That's just the loose data outside of the main archive...

@JourneymanGeek Might try that if this fails :P

Psycogeek

12:39

I just know If i remove my drives from my raid, and sell them to someone with the raid (setup) data still on the drive , sometimes they will act like a total failure.

in normal non-raid setup

Bob

@Psycogeek Yea, these were reformatted after removing from RAID. Was a few years back.

@JourneymanGeek No weird clicky sounds is a good sign, right? :P

Psycogeek

oh , and formatting doesnt fix those blocks the raid cards decide to store stuff in.

but if it was working yesterday . . .

if you had just pulled it from the raid though, it coulda gone all stupid on you.

Journeyman Geek

@Bob I'd still want to know what failed

Bob

@JourneymanGeek Gonna be pretty hard to figure that out, but I'm suspecting controller.

But it still kinda works...

@Psycogeek Nah, was IRST RAID

Journeyman Geek

@Bob if there's a smart failure, you should be able to work out what failed

Psycogeek

12:49

hmm if i did the math right, that drive is , past its prime in "power on hours", what the spin-up hours are would be interesting.

dont hard drives use Dog years ? :-(

Bob

@JourneymanGeek I mean SMART itself seems to have failed o.O

Burgi

ugh!

UTF-8

@Burgi are you by any chance the lima-city burgi?
