10TB helium hard drives for consumers! anandtech.com/show/10496/…

Holy william shatner, there goes the helium reserves we found a month ago

@CanadianLuke i jsut googled it

@oldmud0 There are only 9 100K+ users. They have all been members for more than 5 years. Even Jon Skeet only has 74k on meta.se

12:04 AM

All of those are SE employees, except for one, who is a long-time SO mod

@BenN Probably not. He's just trolling as usual.

seriously? why helium? isn't that wasteful, to dump helium we could be using for medical devices onto crappy consumer hard drives that people just throw away like happy meals

@oldmud0 It's more wasteful filling balloons with the stuff, and then inhaling it ...

12:09 AM

you know the helium drive has failed when you say "oh no....." in high pitched voice

Dang it there is new blister in my foot and it itches

Sounds like pre_fail error to me.

Should I replace it with a helium foot?

@oldmud0 A single quench uses orders of magnitude more helium than a single HDD.

Heck, cooling for maglev uses more.

A party balloon full of helium could fill a dozen drives.

ye but there will be 12x more drives being sold

Somehow, I don't think so...

what, new generation knows to not waste money on such luxuries

I've seen individual parties use enough balloons to fill a few hundred drives.

12:14 AM

what about freon

can we use freon for our drives

Sure, you go do that.

what about lead, and strontium?

Go ahead.

Freon, freoff, freindeterminate

@oldmud0 how would that reduce the air friction resistance?

12:15 AM

Heck I'll put the drive right inside a tesla coil

Journeyman Geek

meh. Might as well go straight to uranium and polonium. GO HEAVY OR GO HOME!

How long have helium drives lasted in the rough enterprise environments?

Journeyman Geek

@oldmud0 now,what did we say about trolling in the past?

@bwDraco they've only been out a few years no?

Well why don't we skip the exotic gases and go right for vacuum

Heat Assisted Magnetic Recording

"Lets heat up the the platter with ~~fire~~ a laser so we can erase it more accurately"

There's also VHS. That's on me, of course.

Still researching on how it's going to work.

Needless to say, VCRs aren't that well documented.

I'd imagine VCRs were very well documented, considering the hundreds of companies designing their own players.

The trick is finding a copy of specs online...

It's a helical design, which means that the head drum must be precisely tuned for NTSC/PAL/whatever

> VHS tapes have approximately 3 MHz of video bandwidth and 400 kHz of chroma bandwidth.

> Clearance processing complete at SYDNEY - AUSTRALIA SYDNEY - AUSTRALIA

Which is why a simple "video to VCR" won't work well

@oldmud0 it worked fine for 20 years. just convert your data to a digital picture, then convert that to analog and store 2 times on the vcr seperated by 1 second. if you are using a different color system, then recover the analog data, convert it to digital, convert it back to the data store. then do all that over again at a different frame rate, and color system.

Yeah but what if the colors are too vibrant and distinct? They'll smudge with one another

user image

user image

@oldmud0 they always will, and huge variations in the analog (and digital when it is there) processing. But your analisis routine would discover the ability to destinguish the data, and use as much analog spaces as nessisary to define what was originally there. this somewhat is what a digital time base corrector already did.

So, what kind of hardware can I generate an NTSC signal on?

12:36 AM

you do realise that NTSC is more of a "standards" and it exists in digital form too ?

So what can you create an analog picture from a digital picture with? about 50,000 possible devices :-)

Yeah but it requires the right clock speed

And generating it from a digital picture kind of puts me at the mercy of whatever device I'm using that does the conversion

Hi folks. Silly question, but I have 20,000+ rep so I thought I could protect any question. But I have run into a few questions—like this one—‌where I can’t. The question is from 2012 (!!!) and has no accepted answer. Is that why I can’t protect it?

@oldmud0 yes mercy me, the variations are enormous. You do know that as a proof of concept device that during some time in the history of VHS there was a recorder that strored the pictures on the tape digitally. and being totally obsolete a recorder of that type would cost you about $5 , if you could find it in the dump.

so... you're saying that if I ever find that device, I could just feed it digital data directly?

12:42 AM

I believe also somone made a computer tape storage system for direct data that used premium quality vhs tapes, but even less of those would exist.

@JakeGould This MSE answer says the post has to be a day old, but maybe that applies to the last time it was edited?

Can you protect this?

(Don't actually, I'm just asking whether it lets you)

@oldmud0 well no that device was still designed for analog video I/O , you would have to do some electronics fudging, and it would not "scan" like a datatape system would, it would be strictly for streaming.

this sounds a lot like a DVR

Journeyman Geek

@JakeGould maybe there's some other criteria for protection?

are you sure this uses VHS?

Oh

Q: "Protect Questions" privilege page doesn't mention the new answer requirement

You can't if the protection wouldn't have stopped at least one answer

Yea that's because protection is not supposed to be pre-emptive.

Makes sense

Journeyman Geek

ah hah!

@BenN Nope. Can’t protect that other post as well from 2012.

You should only protect questions where there's a clear problem of "me too" answers, and usually even that isn't necessary (because the auto-protect catches them pretty quick).

Journeyman Geek

12:45 AM

@JakeGould "provided the question has received at least one answer from a user with less than 10 reputation (such users would then be prevented from posting further answers after the question is protected)."

I believe its the fine print

and with a single poor answer it feels a bit... overkill

I'd rather use the opportunity to educate

Funny, google led me to a handout from MIT course 6.111

@JourneymanGeek Ah. That makes sense. Let at least one fool post a kooky answer before you decide the party has to end.

@oldmud0 i am just indicating that it has been done before. the only thing you could do "new" would be to make a consumer cheap piece of junk from the endlesslly discarded VHS stuff, by playing around with pictures and programs and A/D conversions.

@JakeGould Well, protection doesn't solve that, either... you'd have to block new users from answering old questions entirely. It's rare-ish that random poor answers all end up on the same old questions.

Q: How do I uninstall an application whose installer has a revoked signing certificate

Several years ago I installed an application on my then Windows 7, since upgraded to Windows 10, machine. Earlier today I attempted to uninstall it while cleaning up applications I haven't used in a long time. The uninstall failed with an error message about the installer not being trusted. ...

@Bob Fair enough. Also, I don’t know from this cat nonsense.

or using a dedicated uninstaller of some flavour

sticks duct-tape over @oldmud0's hiss hole.

@Ramhound IIRC usually the signature date must be within cert expiry, and that's all that matters. So it's not an out-of-date issue.

If this cert has been explicitly revoked, then it's more serious than that.

'pedia says that only 2 grades of luminance were used in ArVid which means... ArVid v2!!!

@JourneymanGeek Those "dedicated uninstallers" just run the normal uninstaller. Or hit it with a giant sledgehammer.

So yep. Arvid can be improved upon

@Bob - Shouldn't the author be able to still trust it?

@Ramhound Explicit revocation? Nope. I think I've run into this with revoked certs in browsers before.

I suspect there's some way you can get around it, but it won't be pretty.

@Ramhound Maybe removing the signature and running it as an unsigned installer would work/

12:59 AM

That comic is honestly describes my entire experience at Superuser at times

at least the internet has an off button, drama in real life continues even after the person is gone.

@Ramhound VS has a signtool utility that can strip the signature

@bwDraco I mainly use dash charge - since I haven't been affected by the battery life bug on the current OP3 release, I just pop my phone into charge in the morning

Journeyman Geek

1:11 AM

@Ramhound heh. Yeah, you more so than most. I swear you've gotten more complaints than any other non troll person here for your comments ;p

I know some of those same people, would force me to leave a comment, when I issue a vote

If that ever happens, "NT", will become my favorite word

short is the same as dword right

"What is the point of getting 3600MHz DDR4 ram if the best Intel 2011-3 processor (6950X) has a memory spec of 2400/2133MHz and some of the best mobo's for that processor only support up to 3000MHz?"

My politically correct response: if your hardware can support the faster memory, and you are willing to pay the difference for that faster memory, you should use the faster memory. This is the type of question that we really can't answer.

Their Response: Did you even read the question or am I missing something? If your processor and mobo are below the 3600mhz spec (and I can't find any modern…

(The memory frequency listed on Intel's specification isn't the maximum frequency the CPU supports) that is the reason XMP exists (which I believe is the one that is an Intel creation)

The software that user was using is: netlimiter.com by the way

@Ramhound yea that has come up before. that the Intel ARC data showed only certian ram frequencies (like say 1333 or 1600). people were saying that is why the memory did not work. I do not believe that is correct, although it seems like the "spec".

Journeyman Geek

@Ramhound high frequency ram is typically pointless outside certain specific situations

Q: DDR4 ram, how fast is too fast?

What is the point of getting 3600MHz DDR4 ram if the best Intel 2011-3 processor (6950X) has a memory spec of 2400/2133MHz and some of the best mobo's for that processor only support up to 3000MHz? Assuming you are overclocking, then speeds of 3600 still don't make sense, or do they?

Journeyman Geek

but that's the sort of place where I wouldn't bother commenting.

Alex does not :$

Journeyman Geek

If I must, I'd answer

But I believe it to by my opionion if something is "too fast" I am running 1333 MHz DDR3 because of price

32GB 1333 MHz was $300 cheaper then what I could be using

for virtually no performance boost.

I would have to get 3000 MHz to get any real performance increase and it would barely be twice as fast.

@Journey Regarding the Macintosh G4 comments you asked about the Mactracker.

-1

A: RAM Specifications for Power Mac G4

Try Mactracker, a Macintosh application (free to download) that has information about Apple products back to the Apple I in April 1976. Mactracker lists 20 models of Power Mac G3/G4/G5 computers. The information includes an overview, software, memory and graphics, connections (Ethernet, USB, Fir...

I realize the question is stale. But it asked how to find memory specifications for out-of-production Macs.

Journeyman Geek

@creidhne more that the answer reads like an ad

I'd go "You can use Mactracker on (another mac|pc) to find this - you can key in (information) and it would give you a screen with the relevant information"

then screenshots and such

Well, if it's an ad, it's one that shows that Mactracker has the answers about memory for every Mac ever made.

so many numbers, as all high numbered memory has more wait states involved. you have to have the whole thing, the high speed and the low latency to get the large memory bandwidth. It is like buying a LCD monitor with 1ms (claimed) refresh rate, only to find out there is a 45ms delay in the processing engine to get it from the card to the screen. Just give me the real number that i care about , it turns up to "11" :-)

Journeyman Geek

see point 5 here meta.superuser.com/a/5330/10165

@bwDraco its not spam

@creidhne agreed. So, what does this run on?

I saw no reason to flag it. I was rather puzzled by the downvote, though.

Journeyman Geek

1:35 AM

Another OS X machine? Would it run on mac classic?

@Journey I can do that, but screen shots are on the linked website. I included screen shots relevant to the question. Do we want a tutorial on how to use a free App?

The machine uses SDR SDRAM.

Journeyman Geek

Would you run this on the machine you want to find ram for or another one?

@creidhne actually? Yes

The app is also available for iOS devices.

itunes.apple.com/us/app/mactracker/id311421597?mt=8

Journeyman Geek

@creidhne its a quirk of the site, since we don't allow software recommendations (by community consensus) and this is a workaround for that.

1:37 AM

@Journey Yes, Mactracker runs on Macs back to OX 8.5. See Download on the website.

(I got commenting cause someone tried to protect the question and couldn't, and I'd rather get people to improve a answer than delete it)

1:38 AM

@Journey It's not a software recommendation. It's a resource for information about legacy Macs that is hard to find in one place, anywhere else.

I'm rather surprised the app's developer went to such great pains to make it run on a nearly 20 year old OS.

Journeyman Geek

@creidhne its a software recommendation ._.

Also, those screenshots need like 500% more JPG.

@MichaelFrank ALL THE ARTIFACTS!

1:41 AM

@MichaelFrank Yes, if they were specific to the model of the G4 in question, but we don't know that.

@creidhne When recommending software, we tend to expect that the answer includes how to use it to solve the OP's problem. Otherwise, it wouldn't directly address the question.

@bwDraco Doesn't do much for the wads.

@bwDraco That's because Clevo designs are different (and roomier).

@Bob I find a soft brush helps.

Also depends on the kind of dust in your environment.

and for my PC, I tend to use cheap felt to clean, since dust sticks really well to it

@Bob I've done this on my old HP laptop and never had dust accumulation issues on that machine, either.

Some types of dust blow right out. Others form large clumps that must be physically removed.

That Brazilian Guy

@bwDraco This = blowing compressed air from the outside?

Speaking of cooling issues, we have a few old P4-based Dell workstations at my college campus where the fan keeps revving up. I've opened up one of them and found very little dust in the HSF assembly. The heatsink was also merely warm to the touch. Is bad thermal paste the issue here?
