Comment Re:Went and saw it at 48fps (Score 1) 599

And two things I have to say:

1) If you get the least bit motion sick, don't go see it at the high frame frate in 3D. Normally I don't, even when seeing IMAX/OMNIMAX, but this film I did.

As a counter point, I went on Friday with my sister and another friend who are prone to feeling motion sickness when watching 3d movies.

They both found that with the HFR actually made the movie as a whole easier to watch. (For my sister in particular, it was the first 3d movie she'd been able to watch without feeling motion sick throughout.)

They did, however, have some vertigo from some of the pan shots looking downward.

And the rich could probably avoid being taxed on some stuff by attending more company promotional and marketing events. You'll still get them on private dinners at expensive restaurants etc, but not on the big ticket items - yachts, planes, maybe even property (Disney won't have to pay tax on Disneyland, the tax is just on the people buying the tickets right?).

Haven't you just described things being flipped? In your corporate yacht scenario the individual doesn't get taxed, but the company pays tax when they purchase the yacht.

In the Disneyland example, they're being taxed on the materials for every new ride they build, the fabric for the costumes they buy, etc.

Comment Light fastness is important to consider as well (Score 1) 712

If you're going to be leaving drawings out where they'll be exposed to sunlight, whether or not the inks are light fast is going to be important if you want to use your drawings in the future.

Some cheap pens will fade rapidly and be difficult to read (especially for thin lines) in a matter of months.

Comment Other sources of BPA might be worse (Score 3, Insightful) 388

There's also the finding that many types of thermal paper contain much larger amounts of BPA than food packaging:

Would be interesting if the link between obesity and eating fast food was only partly due to the food itself and partly due to handling the receipts.

Comment Nothing but barometer, not barometer + X (Score 1) 663

Each of those examples calls for more than just a barometer:

a) Measure the height of the barometer, and carefully laying it end to end on the side of the building, find how many barometer-lengths high the building is.

Requires the barometer, some type of measurement device, and a ladder or other way of scaling the building.

b) Measure the length of the shadow of the barometer and the length of the shadow of the building. Using proportions, work out the height of the building

Requires the barometer and some type of measurement device.

c) Locate the custodian of the building. Say to him, 'If you tell me how high your building is, I'll give you this barometer".

Requires the barometer and a custodian.

Comment Re:Sue them for damaging private property (Score 5, Interesting) 617

My neighbor's dog come into my yard and damage my yard...my neighbor has to pay for restitution

Except Monsanto didn't plant it or own the original seed, a neighboring farmer did. If your neighbor's dog digs up your yard, the dog's owner is liable, not the pet store where he bought it.

Except from Monsanto's perspective the neighboring farmer doesn't own the seed -- he just licenses it.

Say we modify the analogy a little -- assume the neighbor's dog is attacking someone in your yard.

If the pet store knows the dog has a history of attacking people and rents the dog to your neighbor without telling him of the dog's history, who should be liable when the dog attacks someone?

Comment Re:Scan for quality? (Score 2) 172

Because it's used for accessing corporate email. In many organizations, that's the only choice if someone wants to access their mail on a phone.

The biggest selling point is that it keeps corporate data segregated from the rest of what's on the device. (If someone's phone is lost / stolen or leaves a company the end result is that it allows for a remote wipe command to clear out just the data for Good)

Last I had looked at it (close to a year ago), usability was lagging behind the native email clients for Android / iOS, but they did seem to be making slow progress.

Comment Article and post define "sign up" very differently (Score 1) 151

The original posting talks about "signing up" in the general context of creating an account on a site.

The article, however, seems pretty clear in talking about "signing" up to receive emails. (And very clearly puts forward that "no option == spam")

Looking at the two modes of failure for a user receiving emails you can have:
- False positives: user starts receiving email, but doesn't want it
- False negatives: user doesn't get any email, but does want it

The main debate in the original article boils down to:
- Single opt-in results in fewer false negatives, but more false positives
- Double opt-in results in fewer false positives, but more false negatives

At which point the question is one of whether it's better to optimize for fewer false positives or fewer false negatives.

In the context of the original article, if someone is signing up to receive emails, both of the following situations will lead to the original user not receiving the emails that they requested:
- If they misspell their address and the email goes to someone else
- If they enter a different address purposefully and it goes to someone else

For the user signing up for messages, the opt-in message isn't something they specifically wanted -- it's a barrier that prevents them from getting what they wanted (as such, a double opt-in request could be seen as a false positive). For someone whose email was entered in a form by someone else, any message they receive may be seen as a false positive (including a double opt-in request).

Comment No need to keep track of a "list" (Score 1) 140

I'd considered this sort of thing a while back -- there's really no need to use a set list of passwords.

Assuming that the passwords are being hashed, you can have a lookup table where you store:
(Password hash) + (Current # of accounts using that hash)

By setting a threshold for the ratio of (Current # of accounts using a hash) to (Total # of accounts), you can reasonably control the average entropy of passwords in the system.

For example, if you have 100,000 users in a system and set a threshold of 2%, the system would stop allowing anyone else to use that password.

Would be an interesting experiment to see what ratio comes up with the best balance between being secure vs. being too annoying to users.

The big downside of that type of dynamic system is that for low numbers of users, it may become easier to brute force which passwords are in use by iterating through the "change password" process. (Setting a limit on how many times an account can change their password in a given day would help slightly, but might not do much to stop a distributed attack)

In the case of Hotmail (or any other large provider), they're already starting with a large data set, so they'd be able to avoid that issue.
