"the pilots failed to apply correct procedure for unreliable airspeed." This is a good candidate for 'aviation understatement of the century.' The pilots failed to apply correct procedure for flying an airplane. — reirab3 hours ago
@JourneymanGeek Will be available locally for ~$35 this afternoon.
(Lets see. I have spending money. I have fixed expenses (Baen monthly bundle and my phone bill). I'm still not sure how long I go between farecard topups.)
Which I really need to keep track of, rather than just taking out the money from the cash stash.
Short answer
There's currently no failproof and scientifically proven way to guarantee 30+ years of cold data archival. But some projects are aiming to do that like the Rosetta Disks project of the Long Now museum, although they are still very costly and with a low data density (about 50 MB).
I...
OMG
Sub-200 rep user posts genuinely exemplary answer.
he condemens hard disk for thier know life, but fails to acknowlege that in "cold" storage the biggest problem is not loosing the magnetics or the drive failing over time, but the motor locking up from lack of use :-)
Recording layers made of pure gold aren't subject to the sort of degradation ordinary discs suffer from, which use silver or materials that do degrade over time.
The shelf life of a normal, non-archival optical disc under reasonable storage conditions is about 10-15 years in my experience.
He says you cant test stuff, but if it is on a couple of HDs you can certannly test that 10times faster, and when the next media comes along, you can ge it off it 10 times faseter.
I have a cold storage room i can actually get you copies of stuff from before 1986 :-) but it sure as heck wont be a 1-1 copy because 90% of it is analog. I can make you a copy that looks about 99.9% the same as it did though :-)
The DVD though most of it indeed acts like it will live another 20 years, but much of it is beginning to de-laminate. the storage room is de-humidified and cooled, but there is still oxygen :-( bloody stuff make everything organic
The quality of the medias glue , assembly the plastics , cannot be "accelerated tested" much like the bloody paints they sell us which should be able to be accelerated UV tested, that still do not survive well outdoors in the sun for 1/4th the time they claim.
I can show you films that were from 1960's and some before, that will still play today, Falling apart at every glue and tape joint made in them to edit. :-) the single solid piece of extrude is still alive, but easily broken, but all the things used to hold it together make them a total pain.
I just tested my earliest SD card a 32mb :-) i figure it is ~20 years, the data is still there, but i couldnt compare it bit-bit to be sure.
Yea old 40gigs and all would act like the data wasnt going anywhere. the data density was sooo low on them compared to today.
The HDs are open air , via a tiny little hole that is filtered (as we al know) so moisture could ingress. that is why i didnt understand why they had not yet made some sealed ones. although they can be put back in a static bag, with an oxygen adsorber and should work fine.
Here is another odd one, shipped dvds , and they were shattered in transport, never seen such a thing, the box was in the usual shape one would expect after a transport, , the dvds were in boxes to protect them. It was not even that cold. it was the same media that i had used and shipped at other times .
While a HD can claim many Gs of shock, some specific models are known to (how to say it) pop thier motor axel out of axis, but other than that , i wonder how many be it aluminum or glass ceramic have had that kind of demise from rought transports.
"Suppose the Vikings stored data on blu-ray disks; what are the odds we'd have the knowledge how to interpret that data now" well if it is that important I will get my chisel out :-)
@Bob yea most store bought disks have held up in time better than dye change disks. But people were saying that some of the early blu-ray disks that were glass mastered did not last time. I figure Facebooks blu-ray machine at least has no humans touching them .
The analog LaserDisc format has proven to be particularly prone to the reflective layer failing resulting in increasing grain and noise in the image and sound over time, and these are pressed discs
The principle is the same for digital optical media. The reflective layer will fail, it's just a matter of how long. Gold layers last much longer than ordinary aluminum or silver layers.
Yes, the dye is part of this as well, but good dyes can last a long time.
uncompressed analog gets an error, you see a blip, highly compresses digital gets 1 bit wrong and you (could) get a unreadable mess until the next keyframe. sooo realiability would be to have uncompressed unencrypted digital. then a blip is still a blip.

On September 7 2010, during a windstorm, my office experienced multiple electrical events which we were aware of only because we could see fluorescent lights flicker for moments throughout the day. On several occasions, one or two computers would shut down or restart during a flickering event. A...
Oh this is just another insurance policy that never intended to pay anything to anyone at any time.
they should just tell the truth when they get on the stand. "your honor we only sell the policy, as you can see in the fine print it does not cover anything"
"The insurance policy covers data and software lost due to "electromagnetic injury" caused by (1) Blackout or brownout; (2) Transients, spikes, surges and other power failure; and (3) Airport security check, and radio or telephone line interference;" "
It would depend on where in asia, and the connection. And whether the cables were eaten by sharks. We've been having high latency between us and our HQ in london cause the fibre optic cable between us was severed. — Journeyman Geek ♦15 secs ago
And research through the years would show that those specific items would not specifically cause "electromagnetic injury" so the policy was designed with great thought to cover nothing.
When buying a used car , the dude was trying to sell me a insurance policy that would , in his words "make sure i was covered for anything that could go seriously wrong" and end up making the used car cost much higher. I read the policy from end to end, and it only covered if the engine or transmission fell out while driving down the freeway. I started quizzing the guy about how the policy would cover Anything the salesperson had represented.
By the time i got done the guy was Red faced screaming at me at the top of his lungs untill a gathering of other sales people showed up in the office, asking if he wanted the police.
All i was saying, (very calmly) was the paperwork does not say it covered , what he kept saying it would. and if he would like to put his Words in writing.
This article is about a legal term. For the sociological one, see Misrepresentation (sociology).
Misrepresentation is a concept in the contract law of England and some other Commonwealth countries, referring to a false statement of fact made by one party to another party, which has the effect of inducing that party into the contract. For example, under certain circumstances, false statements or promises made by a seller of goods regarding the quality or nature of the product that the seller has may constitute misrepresentation. A finding of misrepresentation allows for a remedy of rescission and...
The problem in the US is in a courtroom Nothing he said when selling the item would make a lick of differance in the courtroom, only the paperwork as signed. And if i had recorded him without his knowelege that is not legal either.
I think that is basically a wrong thing the judges easily rely on to solve cases. i had a witness that could (somewhat) reflect the "trade agreement" he was selling at the time.
He had actually added the policy to the price of the car, along with 2 other Iffy items , and was trying to pass this whole array of items (including the needed ones) as just the general transaction for any used car sale anywhere.
I did end up with the car, and saved $1200 (of a total of 10K) from being added to the price. Had to sign only one thing that said i specifically refused , and would deal with that item myself.
After i looked them up on the web, and . . . well i should have done that before showing up :-)
I placed some files in a folder and placed that folder in a folder on a server on my university. When my teacher checked my folder, the folder was empty. I still have the files but my teacher wont accept my work until i can provide proof that it was a fault in the server.

shouldn't there only be one revision of a program with perfect in the title? Word perfect 10, does that mean the first one was just so so. Perfect disk 12.5 , was 1-12 imperfect? final cut pro 10, so i guess the first one was rough edit?
If i get "the last smartphone you will ever need" will i be able to get a battery for it?
I hate the ridiculous "move to SD" feature of stock android. A 300 MB game moves 9MB to SD and 290 MB stays on the data or obb internal folders. SO USEFUL!
I quit bothering with the lack of applications space, and organised the "games" and things in folders on the home screen, to Install at will. and remove when done.
@Bob Nearly all of the "big" android games (the ones where you get a "this app is really big, download it on wifi only" alert) will install first a "base" content and then an "extra files", those are usually download on the data folder or obb folder
But seriously now; as I kid I envied all my friends who could buy neat consoles. Now I got a job and bought consoles, I have the money but not the time. ;_;
@ThatBrazilianGuy You'd have to ask @Psycogeek or @allquixotic (not that they have personal experience, but they're much closer) - I remember seeing figures of $8 and $10 /hr?
The other day I saw a guy in reddit saying he just laughed and walked away at an IT offer of USD 15 / hour. Something mostly basic IIRC. Damn, if I could earn USD 15 / hour I'd quit my current job, I make about USD 5/hour here ;___;
That's about 30 mins from the CBD by road or train.
If you're happy with an hour away... I'm guessing maybe 75% that price.
If you want to live about 2 hours away (hard to say it's Sydney anymore, but we are one of the sprawliest cities in the world...)... then you're talking "cheap" houses.
Even that rose crazily.
I remember back in 2007... 300k? About an hour away.
@Bob that being in the large city (sydney)? which would be similar to trying to buy a house in the middle of SanFrancisco. prices being double for the same basic thing as the outlying suburbs, droping 1/2 again for the cheaper suburbs , further from the $$$ work. and again another 1/2 for living in the middle of a swamp
