Thank you for that.

Everything I find related to that seems to have been shut down, are you getting better luck?

gen.lib.rus.ec and bookfi.org both work for me, some time ago I investigated the origin of those collections and apparently they began as a set of 30+ dvds that have been distributed presumably primarily in russia for quite some time.

Especially in math and physics they are every poor graduate students dream. Even large libraries have only one copy of some of those books stuffed away in some underground vault.

> Has the human race produced 464,000 hours of video content? Far more than that... YouTube alone claims "100 hours of video are uploaded to YouTube every minute": https://www.youtube.com/yt/press/statistics.html ...which comes out to 144kh/day. In other words, one of these discs would be enough to store ~3 days worth of contributions to YouTube. So a box of these discs, let's say 1000 of them - which isn't all that…

The majority of that is junk anyways. But I suppose some people obsessed with archiving everything wouldn't filter anything. If I were to grab "everything" from YouTube I would at least limit it to subscriptions and only subscribe to channels that don't upload bogus junk.

Then the valuable commodity would become directories of worthwhile content. You would have people doing deep dives into the crap to find the locations of a few good pieces to share with their buddies or trade.

Anyone remember the company from about 2000/2001 called Constellation 3D? I do I lost my $3,000 investment when they went belly-up, doh!

They made a fluorescent multilayer DVD and a credit card shaped ClearCard the DVD which I believe the goal was to store several hundred TB of data.

And this was about 14 years ago!

A big problem with spinning disks is that storage grows inversely with the area of the dots, while reading and writing speed grow inversely with the diameter of the dots. If you store 100 times as much data, all else being equal, time to write a full disk will be ten times as large. Ways around that are increasing rotation speed (been there, done that. There is little to gain here without making the disk a lot strong…

Stronger ≠ heavier.

The parameter of interest is specific strength, which is the material's (ultimate tensile strength/density).

I forget what the plastic in DVDs is, but it could probably be reinforced with carbon fibers (chopped, nanotubes, etc.) to give a useful increase in rotation speed.

> Every day, humans are producing more data than ever before - around 90% of the world’s data was generated in the past two years alone - and there will come a point when our data storage centres and the cloud can no longer keep up.

Is this true? Can anyone point to a some kind of study showing convergence of storage capacity and data production over time? I was under the impression that we've got far more storage than we'll need, at least in the near future.

As of a couple of years ago, the entire content of The Pirate Bay[0] was under 100MB[1]. Think about that for a moment - it's the index for one of the largest collections of publicly available content in the history of humanity, and it fits in my wallet 80 times over[2]. [0] Not the P2P content that people download - just the main site itself, containing all of the magnet links, etc. TPB's 'content' is literally just…

> the entire content of The Pirate Bay > Not the P2P content that people download I think you're confusing different definitions of 'content' here. Also, there are many more sites that have publicly available indexes of other links much greater than the pirate bay, google.com for example. Furthermore, 8GB is relatively small for a flash drive nowadays, e.g. here is an 128GB micro sd card: http://www.amazon.com/dp/B00…

Sandisk just released a 512GB SD card a week or two ago:

If this is real and can be commercialized it could lead to some pretty devastating fallout for the entertainment industry. You've got to know that there are a few obsessive archivists out there with pretty comprehensive collections of films spread across rooms of RAID arrays. When they can start backing those collections up for friends onto a single disc, ie a single disc that has more films than you could possibly w…

> more films than you could possibly watch in your lifetime I was curious if this statement was true... So assuming, 4.4 GB her HD film & 2 hrs long each, you can fit roughly 232 films per TB or 232,000 films total (for 1000 TB), that's 464,000 hours of HD content or 53 years (!) back to back. So, yes, that statement is true. Now the next logical question: Has the human race produced 464,000 hours of video content? L…

>Let's assume there are around 100 cable channels showing content in HD video 24/7 (with no overlap, there are more but a lot of duplication). That's 2,400 hours of content a day, 876,000 hours a year or 101 years back-to-back worth of watchable content shown each year.

I'm thinking that 100 channels provide exactly 100 years worth of content per year instead of 101. Unless you rewind the good parts :-p

Given Australia salary scales, this may be a typo, 180,000 would sound normal.

Nope, it's $18k, but it's not a wage. It is low (Australia doesn't have the money that US universities are awash in), but it's for things like international travel to conferences and the like. http://www.swinburne.edu.au/media-centre/news/2014/08/victor...

True, its a pure travel scholarship, with all likelihood the student won't even get to touch the money. It will all handled by the university's finance department (it was in my case). And $18k is huge for an Australian travel grant, they're usually just $2k to $5k, some examples:

$1.8k in Perth http://www.postgraduate.uwa.edu.au/students/funding/travel $1k to $2.5k at Uni South Australia http://www.unisa.edu.au/student-life/global-opportunities/tr... $2k to $3k at Ian Potter foundation http://www.ianpotter.org.au/travel

etc.
