I don't think cats understand palindromes

Gotta love sudo rm -rf

Journeyman Geek

someone clearly loves living a little dangerously

qasdfdsaq

To be fair, it was either that or sudo chown -R then non-sudo rm -rf but that would have achieved the same thing.

And it's not like you can't fuck up with chown or chmod either.

Journeyman Geek

Yeah

tho you could sudo -u user rm -rf

which would be relatively safe

qasdfdsaq

Well the files were owned by root.

Journeyman Geek

oh

Yeah, that would be alright

qasdfdsaq

13:06

I copied some files from another user's folder to my own folder, as root. Hence need to be root to delete.

Journeyman Geek

You can't really sudo rm -rf that easily any more IIRC

qasdfdsaq

You can't sudo rm -rf **/** that easily

Journeyman Geek

yup

qasdfdsaq

But plain sudo rm -rf <non-root-folder> seems to be treated just the same as any other sudo command

Journeyman Geek

anyhoo the filter caught it and marked it as spam and it wasn't delivered to anyone in the company apart from the people in HR

qasdfdsaq

@DavidPostill Urgh, ramhound repeating the same false information over and over again

DavidPostill

@qasdfdsaq Are you talking about the clean room comment?

Burgi

i thought it was a reasonable comment based on how grimey my house is...

qasdfdsaq

Yep.

DavidPostill

13:21

@Burgi Sometimes the paperless office has disadvantages ;)

qasdfdsaq

@Burgi Dust itself isn't a huge problem. Adhesive grime (as in, e.g. oil) is real bad.

DavidPostill

@qasdfdsaq CanadianLuke answered with the same thing ...

qasdfdsaq

@DavidPostill He's also wrong. But I haven't had to tell him ten times already.

Burgi

@qasdfdsaq you mean like the oily grease on your hands....

qasdfdsaq

@Burgi Yes. Fingerprints = bad. Dust... meh.

You'd be surprised how hard it is to actually damage a platter though.

DavidPostill

13:23

Well dust is bad if it's still inside after you reassemble right?

qasdfdsaq

I've taken screwdrivers to spinning platters on a powered and working modern drive in the past.

DavidPostill

Did you SMART before and after?

qasdfdsaq

Nope. The whole point was to destroy it ;)

Burgi

i think the comment and the answer are a reasonable explanation based on 99.9999999% of it occuring in reality

qasdfdsaq

I did however disassemble drives and run them just sitting in a dusty office without the lid on, and surface scan showed only sixteen (!) bad sectors. Ten of which were there before.

DavidPostill

13:25

Ah. I thought you meant it still worked afterwards ;)

Journeyman Geek

He also needs to make sure the platters are aligned the same way I suspect

qasdfdsaq

Well I dropped a screwdriver on a stopped platter once, and it still worked afterwards.

DavidPostill

I suppose diamond dust might make a mess ...

Burgi

its high precision electronics that requires a skill/technology level beyond that of the normal pc user

DavidPostill

@Burgi @qasdfdsaq is not normal ;)

Burgi

13:27

i'm going to engrave my own CPU with a chisel and a hammer

qasdfdsaq

The thing with dust is, these things spin at 60 revolutions per second. The platter experiences close to 2,000 Gs of cetripetal acceleration.

In other words, unless it's glued to the platter, dust pretty much clears itself off. If it doesn't, then the stuff that's causing it to stick there is a bigger problem than the dust itself.

@Burgi One would argue having disassembled a drive and asked about stuff on SU is already beyond most normal PC users.

DavidPostill

So the dust flies off. If it happens to be the direction that takes it under the head as the head lands then what happens?

Journeyman Geek

@qasdfdsaq I'd be more worried about the actual disassembly

Burgi

7200 rpm != 60 rps....

Journeyman Geek

Burgi

my new boss used to work for HP and wants me to write up some sort of secure development procedure. i think he is mistaken that he thinks this place is semi-professional...

qasdfdsaq

@DavidPostill The heads are already broken.

@Burgi Most drives aren't 7200RPM anymore

Well, OK. Most of my drives aren't.

Burgi

5400 rpm != 60rps

qasdfdsaq

s/60/over 60/ then :-(

You know there is a reason I failed math at school, twice.

Journeyman Geek

@qasdfdsaq I try to get 7200rpm drives ;p

Or SSDs

Burgi

3600 RPM would give 60 rps

qasdfdsaq

13:38

4200 RPM laptop drives! Yay!

Burgi

got a link?

qasdfdsaq

Yeah, I don't have any 7200 RPM drives left.

Journeyman Geek

0_0

Burgi

slowest i could see were 5400

qasdfdsaq

@Burgi They're pretty old, but used to exist: google.co.uk/search?q=4200rpm+drive

Journeyman Geek

13:39

@qasdfdsaq most of my 5400s are pulls

(and got swapped out for SSDs ;))

qasdfdsaq

All my storage drives in my server are 5000-6000 RPM.

Everything that isn't a 4TB+ 5000-6000RPM HDD is an SSD.

Burgi

i went for a 4TB HHD last time around

qasdfdsaq

I always use low-power drives in my storage sever, and everything that isn't low-power bulk storage is an SSD.

Burgi

it was on offer

Journeyman Geek

@qasdfdsaq I tended to go with 7200rpm HGSTs ;p

qasdfdsaq

13:40

I've been using <6000 RPM drives for five or six years now, simply for energy savings. Before that I had mostly 7200 RPM HGSTs too

Journeyman Geek

Only 'regular' laptop drives I have is the DOID (which was a pull from my laptop, and supposedly shouldn't work), and the 1tb in my home server, which might be 7200rpm

Burgi

is the energy saving really that significant?

qasdfdsaq

On one or two drives it's not much, when you have 24 of them in a chassis it's the difference between dissipating 80w of heat and 170w of heat.

Burgi

some light afternoon reading.... www-03.ibm.com/able/guidelines

:(

qasdfdsaq

It's also the difference between needing a power supply that can handle 700w peak power at spinup and one that handles 500w.

Burgi

13:44

@qasdfdsaq how did you calculate that? do you have a spreadie?

qasdfdsaq

24 x 3.4 doesn't require a spreadsheet.

Burgi

3.4 being?

qasdfdsaq

watts.

The actual consumption measurements... I made them myself, but several review sites have measurements too.

@Bob, you know all that trouble I was having with control characters in log files and regular expressions and stuff?

Burgi

i thought 3.4 was high but this question suggests it might be low

Q: How much power does a hard drive use?

This is not as straight forward as it sounds. Specs from Western Digital's site for a WD 3TB Green Drive: Read/Write 6.00 Watts Idle 5.50 Watts Looks fine right? Look at this part of the spec: "12 VDC" and "Read/Write 1.78 A". It was a long time ago, but when I was in college that would me...

@qasdfdsaq Ya?

Burgi

Dave

what the hell is negative milk? Is that the inverse of milk?

qasdfdsaq

Nah it tasted quite nice, better than the normal stuff actually.

Dave

I know logically negative milk is while (milk < 0) { do }

qasdfdsaq

15:02

@Dave Yeah, it's like negative energy. You can use it to hold open an anti-milk wormhole that sucks milk in and causes it to self-annihilate.

Burgi

my friend brought "cheese-flavoured slices" to a bbq last year

Dave

Nice

Burgi

they contained 60% cheese substitute

whatever the hell that is

Dave

@qasdfdsaq: Letting milk go sour, wouldn't that be considered negative milk?

If only milk could be bent in a way to make it taste the opposite.

DavidPostill

@qasdfdsaq As one of the close voters I actually read the (original version of) the question, the first sentence of which read "I am shopping for KVMs to take to job sites." It was later changed to "The reason I ask is that I am shopping for KVMs ...". References to shopping were deleted more than an hour after the question was asked...

qasdfdsaq

@DavidPostill So? That does not make it off topic. Wanting to understand the technology to make an informed decision != asking for a shopping recommendation.

Pretty much all the "allowed" questions he linked are for the same reason. "I want to buy an adapter. Tell me what I need to make a decision".

Bob

@DavidPostill I have to agree with qasd here. We shouldn't close questions for merely mentioning the reason for asking. He was not asking for an actual product recommendation.

DavidPostill

@Dave Technically milk is an emulsion " In foods, emulsions usually contain oil and water. If water is the continuous phase and oil the disperse phase, it is an oil-in-water (o/w) emulsion, e.g. milk or cream. In the reverse case the emulsion is a water-in-oil (w/o) type, e.g. butter"

Bob

In fact, we explicitly allow questions asking for technical aspects behind the choice.

DavidPostill

15:18

<shrug> I've voted to undelete.

Bob

> my question is: What one, single display port type should I look for on a monitor that is able to support all of the other types while minimizing costs of adapters

qasdfdsaq

Not to mention, if the question could be fixed yet remain faithful to the original just by deleting two lines, they were clearly not the focus of the question.

Bob

"while minimizing costs of adapters" is the only iffy part there

That was taken from the original revision.

qasdfdsaq

Oh, I can't see the original revision. Or any revision. Bleh.
