Facebook Experimenting With Blu-ray As a Storage Medium

Chuckstar Re:Right to be forgotten? (193 comments)

The right to be forgotten should apply to Facebook as well. What it doesn't apply to is first-party stuff that gets covered by freedom of the press, as that is considered to trump the privacy freedom. Don't ask me how they decide whether or not to consider Facebook "press". I quickly get lost in the mind-boggling logic of telling Google not to list something in an index that is sitting publicly on a website.

Facebook Experimenting With Blu-ray As a Storage Medium

Chuckstar Re:Why not just use hard drives and then store... (193 comments)

You could have a robot unplug/plug HDs, but once you're accepting the latency of disk changes and spin-up, I imagine Blu-Ray disks would be much, much cheaper than a similar capacity of HDs.

Facebook Experimenting With Blu-ray As a Storage Medium

Chuckstar Re:Get facts straight (193 comments)

I think the point is that if you want access to stuff from an HD, it's got to be plugged into something. The more storage you have, the more of those "somethings" you need, along with the routers and logic to connect them all together. All of that stuff takes power, even when the HDs themselves are asleep.

You could do something similar to the Blu-Ray setup, where a robot plugged/unplugged hard drives instead. But I'll bet once you're going to accept that kind of latency, a robotic Blu-ray juke-box with lots of Blu-Ray disks would be a whole lot cheaper than a robotic HD juke-box with lots of HDs (the lots of Blu-Ray disks vs lots of HDs being where the savings would really be found).

Facebook Experimenting With Blu-ray As a Storage Medium

Chuckstar Re:Everything old is new again. (193 comments)

Tape may have better density, but Blu-Ray probably has better access time. Sounds like this is still stuff they want to have "live", they are just willing to have be a little "less live" than HD latencies.

Tesla Removes Mileage Limits On Drive Unit Warranty Program

Chuckstar Re:So there is a problem... (174 comments)

The point was that only the GM cars have the problem that heavy stuff attached to the key can turn your car off in the middle of driving down the road. It's especially a problem with rental cars, because they have heavy stuff attached to the keys as a matter of course.

"Secret Serum" Used To Treat Americans With Ebola

Chuckstar Re:ROI for drug development (390 comments)

There are government grants available for such research. Not all research is done by people looking for billion dollar paydays. Some people just want enough funding to get the research done and draw a salary.

Qualcomm Takes Down 100+ GitHub Repositories With DMCA Notice

Chuckstar Appears elsewhere? (349 comments)

I don't know enough to comment on the validity of the claimed copyrights in general. But I do know one thing: The fact that material appears elsewhere online is not evidence that it is not copyrighted.

The important question is not whether the stuff appears elsewhere. The important question is only whether Oracle's claimed copyright is real/valid.

FAA's Ruling On Smartphones During Takeoff Has Had Little Impact

Chuckstar Re: Exactly (128 comments)

The study only observed how many people used devices some time during the flight. It didn't particularly focus on during take-of/landing/taxi. So all it means is that allowing use during those extra times doesn't encourage the 65% who weren't using their devices to suddenly start using their devices. In other words, not a lot of people were saying "if I can't use it during takeoff, the I won't use it at all."

FAA's Ruling On Smartphones During Takeoff Has Had Little Impact

Chuckstar Point? (128 comments)

I'm not sure I understand the point. I don't remember anyone claiming that more people would use mobile devices on planes if they could use them during taxi and takeoff. It seemed it was always just that the people who were already using devices on planes wanted to also be able to use them during taxi and takeoff.

NASA's Plan To Block Light From Distant Stars To Find 'Earth 2.0'

NASA's Plan To Block Light From Distant Stars To Find 'Earth 2.0'

Chuckstar Re: Can they make a 3D shade? (92 comments)

Gods thinking. But two potential problems that spring to mind:

The petal profile seems to matter, although I admit to not knowing why. You'd have to have your sphere replicate that outline from the various appropriate angles.

Controlling reflection of stray light back into the telescope is already identified as a potential technology problem. A sphere may make that even more of an issue.

NASA's Plan To Block Light From Distant Stars To Find 'Earth 2.0'

Chuckstar Re: Aperture Science (92 comments)

You are correct that there is not an orbital alignment that would passively keep the telescope and shade in alignment with a star. They plan to put the system in a solar orbit (so that the speed at which alignment shifts will be slower than if it were in Earth orbit) and also they will have to actively guide the telescope using ion thrusters in order to maintain the correct alignment during an observation. Because of this, observation windows will be relatively short. This requirement for active guidance during observation is one of the technology risks identified in one of the links above.

Amazon Turns Off In-App Purchases In iOS Comixology

Chuckstar Re:Make a good mobile site (244 comments)

Agreed. I wasn't trying to imply that making a mobile site work that way was hard. Frankly, was trying to imply it was relatively straightforward. It's always possible a big company borks something easy, but I fully expect that the need to switch to the web to purchase a comic book will be only very marginally less convenient than in the app. (I admit that in the app would always be the more elegant system, but it really doesn't have to be a big deal if Amazon is smart about it.)

Not really sure why giving your credit card info to Amazon is any different than giving it to Apple.

Amazon Turns Off In-App Purchases In iOS Comixology

Chuckstar Make a good mobile site (244 comments)

Just make the mobile web site work well, and it's hardly jumping through hoops. Someone mentioned how easy it used to be to buy the next issue in-app. Just make is so when you go on the web site, the next issue is right there waiting for you to buy it (the app can report back which issues you've finished). It would add all of 15 seconds to the purchase process.

I understand there's still a hoop there, but they don't have to be holding it very far off the ground, and it's certainly not on fire. They could easily make it a little hop, not a huge jump.

Back To the Moon — In Four Years

Chuckstar Re:Loses credibility with this statement (292 comments)

Falcon Heavy will have significantly smaller payload capacity than NASAs SLS. Perhaps you mean Falcon X (or maybe they call it Falcon X Heavy, hard to keep straight), which is planned to have similar capacity to SLS. NASA is way ahead of SpaceX in development, but has all of the baggage of being NASA, so we'll see who finally gets a vehicle with such capability done first. Don't bet against Musk.

Who Is Liable When a Self-Driving Car Crashes?

What an absolutely lame response. Those systems exist only as experiments, not as systems that are actually safe to drive on the streets. :rolleyes:

Metal-Free 'Rhubarb' Battery Could Store Renewable Grid Energy

Chuckstar Re:What's the storage density? (131 comments)

Pumping a liquid around at a constant elevation doesn't have a very high energy cost. I imagine you'd lose far more energy through the round-trip chemical reactions than you would through pumping the liquid around.

Metal-Free 'Rhubarb' Battery Could Store Renewable Grid Energy

Chuckstar Re:What's the storage density? (131 comments)

Storage density is only a problem for portable systems. For fixed storage installations, the important question is "what does it cost per ampere-hour of storage?" Inefficient storage that is cheap can beat highly efficient storage that is expensive.

Of course, to correctly calculate costs one needs to include things that are the result of storage density, like land acquisition and construction of holding tanks. But if the storage medium is cheap, it could come out ahead of some higher density system that has a more expensive storage medium.

Even conversion losses become less of an issue if the storage is cheap enough.
