Well, if you don't tell them it's a test call and you pocket dial, I would hope that the 911 call center would assume that you're being held hostage and send police/fire/etc. to you.

So, IMO, that the system isn't meant to handle this type of false alarm isn't reflective of call center capacity but rather fire/police/ambulance capacity (and also annoying everyone involved).
Never mind that none of this matters if you have unlocked the phone and it's on (default protection policy is protect until first unlock, which happens right after turnup). That's gotta be 99.9% of cases. Once the police or apple have a locked phone, all bets are off. Apple can just install an app remotely that gets them past the lockscreen, and unless this is from a cold boot, you have access to all apps and all data. This includes access to e.g. The logs of any configured skype session, the company mails ...

Add to that the usual closed software problems. Apple says they don't have a specific backdoor anymore (!), and they won't let you audit anything.

I'm a total layman, but the UID has to be created at some point and so it can be known by someone. Wouldn't it be the easiest way to just record it for every chip? Apple wouldn't even have know about it.
Rtfa, its about backdoors.
> We'd all obviously find issue with being eaten not because we think it's unethical that the alien wants to eat us (it's unlikely that the ethics question would even come up), but because we don't want to die, as an individual and as a species (I'm trying to say that it's NOT obvious that the issue we would have with such a scenario would have anything to do with ethics, not to make a judgement whether it's ethical or not). And so your argument looks like it's saying "we don't want it to happen to us, therefore it's unethical (for anyone to do that to us, or for us to do that to others)". I know you probably doesn't mean it that way.

I am no philosopher, so I'm sure there are many holes in my argument. :)

> Now, whether it's ethical to eat meat itself. As someone else have mentioned, I've always wondered where do you draw the line? Pigs and cows seem obviously out of the questions, but how about cockroach, caterpillar, corepod, hydra[0]? Event certain plants do sense distress signals when they're being attacked.

That's a really interesting question. I learned recently that some vegetarians consider it acceptable to eat oysters because they don't have a central nervous system. Indeed, this whole argument is about "drawing the line", and it is rather complex and interesting.

> Do we actually know that it's possible for us, as a society as a whole to survive entirely on non-animal products, food or otherwise? Additionally, even if it might be just historical accident that we have a heavy meat-eating society, and another society that starts out without ever using animal products can advance to where we are right now and have a perfectly functioning society, it doesn't mean that it's ever feasible to actually switch to such a no-animal product society. In our terms, that would be a switch from not just from one programming language to another, but probably from silicon-based chips to germanium-bases chips.

You are right that it would take a massive shift, and whether or not it is actually possible is a valid question. Thing is, humans have dealt with massive changes in the past, so if we really wanted to, it seems possible. We aren't really trying, at this point, though.
What about iCloud? It used to be that a user could reset their password and then restore from iCloud backup on a new phone... Is this no longer true?
>Someone's gotta pay our pensions. :).

I can almost guarantee you that this procedure cost more than the expected tax revenue of the resulting child.

If it was paid for with public money (I'm not sure how health care works in Sweden), this was probably not helpful in paying for pensions.
Very interesting and well written paper. They show a deep-neural network (which people thought had more explaining-power-per-parameter) can be "emulated" by a shallow neural network with the same number of parameters.

What Ba and Caruana have shown is that deep neural networks---as architecture---are not more powerful. The previous general opinion (at least this is what I thought) was that deep architectures of the form:

predictions
layer 3 features of features of features
layer 2 features of features
layer 1 features
data layer

would be more efficient (i.e. more explaining power per parameter). Nope. Apparently, a shallow neural network of the form

predictions
layer 1 features (a lot more of them)
data layer

with an equal number of units in layer 1 as the total number of units in deep network,
can obtain the same accuracy. Thus, deep neural networks and shallow neural networks have roughly equivalent explaining-power-per-parameter.

A separate result shows deep convolutional neural networks can be simulated by shallow NNs with a simulation overhead of ~10x.

Another cool observation they make about "installing" the parameters of ML models. We'll use the following analogy to illustrate the point:

ML model <==> hardware
ML model parameters <==> software

Running program X involves (1) buying/renting a server, (2) compiling X for your architecture, and (3) running X. Of course there is always the alternate step (2') of installing pre-compiled binaries.

Similarly, we can think of using a ML model as a three step procedure (1) ML.init() (malloc for Model.parameters), (2) Model.train() (fit parameters to training data), (3) Model.predict(new_datum).

The authors point out the existence of a possibility of distributing models parameters as binaries. They demonstrate an alternate step (2') in which they train a ''FancyModel'', then set the parameters of the simple model so it "simulates" the FancyModel: ''Model.parameters = simulate(FancyModel)''. In other words, the model parameters of a ML model need not be learned through the model itself.

What I find fascinating is it seems deep architectures don't have any more representational power, but they do have more learning power. Something very interesting is going on...
Heh, good point. Yeah, character generators are good learning projects, IMO. Maybe somebody should start cataloging them in various languages / frameworks, ala todomvc.com? :-)

Nice! After playing with it for a bit too long, this was my favourite:

Medical necessity is determined by the needs of the patient, which can be physical or psychological. That's really a standard view in medicine, and thus justifies insurance payments for any required procedures. Examples would be gender reassignment, or plastic surgery.
Does being cynical and sarcastic about this satisfy you?
I'm a big fan of Granny Smith apples and I ate them fairly often for a time as part of my efforts to get myself healthier. I think one of the problems with a study of this sort is that it measures but one dimension of what they do, and I think poorly at that. It measures one trait (amount of non-digestible material) they have and it's link to one outcome (fecal bacteria).

I think there is a lot more to it than that and I think they were beneficial to me because they have a complex set of traits that helped make them ideally suited to a kind of niche need. I am glad to see this, but it's just too one dimensional to draw much conclusion from.
Yes. If you're asserting that "giving birth to a child you carry in a womb in your own body over 9 months" is somehow inherently preferable or special compared to any other form of child rearing, your argument that "this is the exclusive mechanism of human procreation up until recent history" is an argumentum ad antiquitatem and/or argumentum ad naturam fallacy.
good idea! this project was partially inspired by math classes spent in high school plotting pretty polar functions on my graphing calculator instead of paying attention to trigonometry... I'm not sure that mojulo in it's current form will be a useful educational tool but I think that toys similar to this are a great way to impress upon kids a sense of different functions they usually only encounter on paper
It's not a great rebuttal, it's just showing why people with imperative mindsets don't really understand Haskell still. The rebuttal rebuttal is good.

Do notation is not specifically a line-by-line imperative thing, and complaining that it isn't that doesn't make it bad. Obviously, the goal in Haskell isn't precisely to do imperative coding. It remains true that you can hack imperative code into Haskell in various ways effectively.
We are still using computers now the way we were 20 years ago!

It's easy to imagine someone like you in 1995 proclaiming there would not be a Windows 2015, or anything close to that.

Nothing has fundamentally changed, Internet and all. Even tablets, smartphones and multitouch interfaces are still basically the same old thing.

Yep, absolutely. HIV is not nearly as easy to (unintentionally) transmit, and is much more manageable in the long term.

If I was on my death bed and was offered to take a potential treatment that had a 1% chance of giving me HIV, I'd take it in a heartbeat.
I really don't get the issue you have with this. Why do you think it is a bad thing that some people are trying to remove the stigma of cannabis consumption and make money doing it?
This is the fundamental problem: unless you are rolling your own silicon, at some point you have to take some big corporation's word for it that a chip does what they say it does. This fundamental problem is the reason that nuclear launch codes are protected by a relatively low-tech solution:

From what I can understand, if you wanted to hypothetically maximize your security, it would mean turning off iPhone backups.

Apple could also have it set that you must have the iPhone passphrase to restore a backup but obviously those can be "easily" brute forced (because for the restore to work, it must mean you can bypass the old device's UID)

Tim Parks (the author of the OP) has been doing a series of extended blog posts for the NYRB on the practice of reading (http://www.nybooks.com/contributors/tim-parks-2/?tab=tab-blo...).

There are plenty of rational people who believe that and I'm certain they could provide you with convincing arguments for their stance.
I don't mean that "anything legal will become mainstream".

Cannabis though almost certainly will (or at least a step below- general acceptance but not universally used)

Its illegality was an obstacle to widespread acceptance that is being removed.
> Apple has built a nuclear option. In other words, the Secure Enclave allows firmware updates -- but before doing so, the Secure Enclave will first destroy intermediate keys. Firmware updates are still possible, but if/when a firmware update is requested, you lose access to all data currently on the device.

That seems ideal. Let's hope Apple actually does that (probably not).
`struct xtime` and `xtime_get` were added in C11 as `struct timespec` and `timespec_get`:

http://port70.net/~nsz/c/c11/n1570.html#7.27.2.5

There are some differences though. Not only the name and types differ. But also `timespec_get` is only required to support `TIME_UTC` and the specification is not as detailed.

It's unfortunate that the math and science that you took apparently weren't up to your abilities and interests. It's also unfortunate that you didn't like your history either--certainly a lot of history taught in schools is overly focused on dates and kings although I'd argue that learning about the scope of history rather than just post-1800 is valuable.

That said, you seem to lay the blame for all that on having to take what I assume was more or less an English literature class throughout that period (though I doubt it was such in 1st grade). Yes, high school literature in particular can be biased toward writers I didn't like then and (mostly) don't like now. But I personally think there's a lot of value in appreciating great literature (as well as other fiction). I'm sorry you apparently prefer to only read programming books.
But if this is the case, why bother with bullet point 1. to 4. The chip is probably manufactured in China, why spend a thought about whether US law enforcement can somehow via Apple decrypt the data of my phone when the Chinese Government can do it anyways?
> (Apple pegs such cracking attempts at 5 1/2 years for a random 6-character password consisting of lowercase letters and numbers. PINs will obviously take much less time, sometimes as little as half an hour. Choose a good passphrase!)

Do not use simple pin passwords on your phone. In particular, if you use fingerprint access, there is no reason not to have a long, complex password.
In particular Apple provide photo backups and (speculation) may be doing something server side to allow continuity features around text messaging from other devices.

This is getting into speculation about their role in Prism but I'm wondering how the iCloud encryption actually works. They say everything is encrypted while stored [0] but it's not clear (or I haven't found) whether that's using a key derived from the password or something Apple control. Either way I'm not entirely sure there's any way to stop Apple getting it if they're told to given the lack of transparency.

> That's as dangerous as driving while (slightly) drunk, and "hands-free" devices don't make much difference, if any.

I don't care—I'm willing to take that risk. For me it's better because I'm a super aggressive driver when I'm focusing solely on the road. Talking to somebody (or listening to someone talk) distracts me just enough so that I'm not super competitive—I'm happy to slide over to the right and go the speed limit in the slow lane.

> Conversing with a person who is actually present in the car with you is also distracting, but in that situation you also gain some safety by virtue of having another pair of eyes watching for danger, so it's more of a wash.

I highly doubt that. The other person may add more eyes but they have no control. I can't think of a single situation where back seat driving has actually helped me avoid an accident.
I think we just got hit by the ycombinator comments "karma nazi".
As a vegetarian, I think it's perfectly reasonable to draw the line at the complexity of an organiams's nervous system. That's about the closest standard we can use to estimate so-called "sentience".

It does become difficult when you look at organisms with more minimal nervous systems, like very small insects. I personally avoid unnecessary death of insects most of the time, however I will kill ants and cockroaches if they intrude into my home. I'm not entirely sure if this makes me a hypocrite. I suspect it might, since ants and cockroaches may be capable of feeling pain and perhaps even emotions.

So the key is derived from passcode? isn't that 5 digits that are easy to brute force?
A note -- if you're linking to arXiv, it's better to link to the abstract (http://arxiv.org/abs/1312.6184) rather than directly to the PDF. From the abstract, one can easily click through to the PDF; not so the reverse. And the abstract allows one to do things like see different versions of the paper, search for other things by the same authors, etc.

You are correct. Or as I should have stated it, exponential curves have derivatives in constant proportion to the curve -- so if you look at the change vs the current value, it will be a constant ratio.

With a logistic (S) curve, the ratio of the change to the current value will decrease. By the time you get to around 25% of the maximum value, the difference should be visible.

Apple's Censors Tech Mag Showing the Amazing Bending Phone

If someone obtains your phone, and prevents you from initiating a remote wipe (perhaps they have you in custody, or perhaps they have isolate the phone so that it cannot receive the wipe command), it sounds like this technology will do a good job of preventing them from decrypting your data from the phone if you have a decent passcode. They cannot throw GPUs or FPGAs or clusters or other custom hardware at the problem of brute forcing your passcode because each attempt requires computation done by the Secure Enclave using data only available in the Secure Enclave. That limits them to trying to brute force with no parallelization and 80ms per try [1].

However, assuming they have an appropriate warrant, can't they get your iCloud backups and try to brute force those? Maybe I'm being an idiot and overlooking something obvious, but it seems to me the encryption on the backups CANNOT depend on anything in the Secure Enclave.

That's because one of the use cases that iCloud backup has to support is the "my phone got destroyed, and now I want to restore my data to my new phone" case. To support this, it seems to me that the backup encryption can only depend on my iCloud account name and password. They can throw GPUs and FPGAs and all the rest at brute forcing that.

My conclusion then is that when I get a new iPhone, I should view this as a means of protecting my data on the phone only. It lets me be very secure against an attacker who obtains my phone, but not my backups, provided I have a good passcode, where "good" can be achieved without having to be so long as to be annoying to memorize or type. A passcode equivalent to 32 random bits would take on average over 5 years to brute force.

To protect against someone who can obtain my backups, I need a good password on iCloud, where "good" means something considerably more than equivalent to 32 bits.

[1] I wonder if they could overclock the phone to make this go faster?
The thing is, this was given to 3 people with Ebola as far as I know.

One was a doctor from Liberia who died.

2 others came to the US for treatment.

If the death rate of Ebola is 70%, that data is probably germane to the quality of the health care in those affected regions, which makes me wonder if the drug is really what helped the 2 who survived, or the increase in health care quality of the US.

It's just too early to tell, and the article that was linked sensationalizes something that we don't even know is the verifiable answer.
