Ask Slashdot: What To Do After Digitizing VHS Tapes? 255

Posted by samzenpus
from the now-what? dept.
An anonymous reader writes Now that I've spent close to a month digitizing a desk drawer's worth of VHS tapes, deinterlacing and postprocessing the originals to minimize years of tape decay, and compressing everything down to H.264, I've found myself with a hard drive full of loosely organized videos. They'll get picked up by my existing monthly backup, but I feel like I haven't gained much in the way of redundancy, as I thought I would. Instead of having tapes slowly degrade, I'm now open to losing entire movies at once, should both of my drives go bad. Does anyone maintain a library, and if so, what would they recommend? Is having them duplicated on two drives (one of which is spun down for all but one day of the month) a good-enough long term strategy? Should I look into additionally backing up to optical discs or flash drives, building out a better (RAIDed) backup machine, or even keeping the original tapes around despite them having been digitized?

The news hit the developers in the Stockholm office very hard to the point that people were actually sobbing.

Yeah, they probably know how well being bought by Microsoft worked out for Sublogic. Or Oddworld Inhabitants. Or Bungie, even, forced to crank out endless formulaic sequels.

On the one hand, I can't blame notch, because if Microsoft offered me enough cash to retire, I'd sell out. But on the other hand, notch is already a millionaire, right? It's not like he needs the money.

Yeah, not so much for permeation, maybe, but they still quote this as one of the things that help. Could maybe do some for actual leaks - but getting air in would be sad too. The big reason for lower pressure is the lower resistance though - I like paying less in power&cooling thanks to lower power use to keep the platters spinning.

Clever materials choices and lower pressure than on the outside (~40% IIRC). Luckily leakage is easily measured in the product design and testing phase, as well as ongoing QA. So not nearly as much risk to your data as stupid firmware bugs that only turn up under some circumstances after lots of usage. And no, they won't be refillable.

Since I started avoiding bread, potato (not sweet potato), rice, pasta and sugar, I've lost a lot of weight.

I did even less -- I cut the added sugar (specifically fructose) to the AHA recommended limits, but I allowed myself to eat all the other carbs I liked, and as much raw fresh fruit as I liked. Weight fell off me and has stayed off for 6 months now. My waistline dropped by 4". So far it seems I can basically eat as much as I like, including carbs, whenever I'm hungry, and stay at a healthy weight, so long as I keep my sugar intake low. So personally, I'm pretty much convinced that Dr Robert Lustig is right about fructose.

Of course, YMMV, I'm not a doctor, etc etc.

The Christian fundies' fear of Sharia Law is one of the most ironically amusing things to come out of them in recent years. If they didn't spend so much time railing against our consitutitional separation of church and state, maybe, just maybe they might realize that it's exactly what protects them from such an (unlikely) threat.

And civil unrest becomes vastly more likely in a future with runaway global warming and the climatic changes, floods, draughts, food shortages, rising sea levels, mass extinctions, habitat destruction, economic upheavals and the like it will bring. Nuclear power, wind, solar, hydro and geothermal are ALL essential to combat it.

CO2's atmospheric lifetime is something like 1,000 years. How come those who fret about the longevity of nuclear waste never seem to talk about this? With fast reactors that burn the actinides (including plutonium) as fuel, the remaining fission products decay to the level of the original uranium ore (while being considerably more compact) in only a few hundred years, much less than the atmospheric lifetime of CO2.

The hype about "carbon capture" is just that -- hype. But it serves one useful purpose: its utter impracticality shows just how minor the nuclear waste "problem" is by comparison.

Not far from Yucca Mountain you will find hundreds if not thousands of craters under which are buried the fission and activation products of decades of US nuclear testing. They're not reprocessed and contained in silica glass, they were simply mixed (quite violently) with the soil and rock. And yet they don't seem to go anywhere. There is no need for Yucca Mountain to contain reactor waste for even a hundred years because it will surely be removed and burned as fuel in fast reactors. Once people wake up to the fact that global warming is a vastly greater threat than nuclear power, and that nuclear power is just as essential as wind, solar, geothermal and hydro in combating it, people will realize that "spent" fuel from light water reactors is far too valuable to just throw away.

Even with cheap solar and wind we will still need nuclear, at least until somebody perfects a cheap, reliable and long-lived utility scale battery. Otherwise we'll never be able to retire all the CO2-belching fossil-fuel plants to match the varying supply with the varying demand.

I agree that waste in casks at nuclear power plants is reasonably safe but it would still be better to move it to Yucca Mountain. If nothing else, security would be a lot cheaper. It's utterly ridiculous that all that money was spent on a waste repository that, thanks to NIMBYism on the part of Nevada politicians, doesn't look like it'll be used any time soon. At least nuclear waste is the one form of toxic waste that will eventually go away on its own. Arsenic, mercury, lead, thallium and other chemical poisons remain toxic forever.

Facebook Experimenting With Blu-ray As a Storage Medium 193

s122604 links to CNN's explanation of what may be the future of cold (or at least lukewarm) storage at Facebook, which is experimenting with massive arrays of Blu-Ray discs for seldom-accessed user files. Says the report: The discs are held in groups of 12 in locked cartridges and are extracted by a robotic arm whenever they're needed. One rack contains 10,000 discs, and is capable of storing a petabyte of data, or one million gigabytes. Blu-ray discs offer a number of advantages versus hard drives. For one thing, the discs are more resilient: they're water- and dust-resistant, and better able to withstand temperature swings. Their data can be restored more quickly, and they're easier to transport. Most important, though, is cost. Because the Blu-ray system doesn't need to be powered when the discs aren't in use, it uses 80% less power than the hard-drive arrangement, cutting overall costs in half.

rbrandis (735555) writes In a video announcement Thursday on Discovery Channel, MythBusters hosts Adam Savage and Jamie Hyneman revealed that longtime co-hosts and fan favorites Kari Byron, Grant Imahara, and Tory Belleci are no longer on the show. "This next season we're going back to our origins with just Adam and me," Hyneman said in the video, which explained that the change took hold as of the season's last episode on August 21.

Yeah, and we should also ban municipalities from building roads because they discourage private investment in toll roads. All the roads, including the street in front of your house, ought to be sold to UPS. You'd have to get their permission to drive your car on their roads. Since they'd be private property, they'd be within their rights to make any arbitrary rules they wanted. They could ban certain makes or kinds or colors of cars. They could allow you to drive only to certain pre-approved destinations. And don't even think about trying to create a package delivery service to compete with them.
