There is an advantage to the original formulations of QM and they are precisely these. It's true that in Quantum Field Theory you don't see these Bell Inequality ideas and I've seen people working in Quantum Information theory who struggle to prove that you can multiply a wavefunction by an arbitrary phase factor and it is an unobservable change. QFT has real current statistics and Lagrangian densities and Feynman diagrams, which give you a much more tangible feel of what physics you're describing.

In my experience it is just another math course and there is no Physics anywhere.

Heisenberg equations of motion are a good place to start. The original way we stumbled upon quantum mechanics was due to Heisenberg, who noticed that a lot of the wavy stuff people wanted to explain could be explained if Hamilton's equations of motion df/dt = {f, H} + ∂f/∂t were generalized by treating x(t) and p(t) as matrices and insisting that they do not commute, leaving instead [x, p] = i ħ as a matrix version of an "uncertainty principle."

The corresponding quantum equation for an observable Â is that dÂ/dt = i [Ĥ/ħ, Â], which allows you to start (most famously) with a harmonic oscilator Ĥ and derive the Hamilton equations dx/dt = p/m, dp/dt = - k x, precisely due to the failure of x and p to commute.

So you get this direct connection between known physics equations and the quantum theory, and often the same thing which is responsible for driving the uncertainty relation also drives all of classical physics.

What does a particle with some particular wave function look like?

|Psi|^2 in the appropriate basis, I should say.

As it evolves in time it "smears" out according to the time evolution equations, but how fast is the process? Does it occur on scale of nanoseconds? Seconds? Hours?

In quantum mechanics there is a discrete energy level spacing ΔE, and the answer is that no observable can change much faster than ħ / ΔE. For the harmonic oscillator for example, nothing can change much faster than 1/Ω by this criterion.

What exactly is an example of a measurement?

This can get a little touchy but a good example is a photon hitting a photomultiplier tube and generating a click -- especially if you start to play with the polarization of the photon to generate entanglement and so forth.

Edit: With all that said, I highly recommend watching Feynman's New Zealand lectures which explain, among other things, why CDs show rainbow patterns (in a time, sadly, before people had CDs and so Feynman kind of just says "I wish I could have brought you an example.") http://vega.org.uk/video/subseries/8

So, this is maybe a silly question, but methodologically, how did researchers establish that? Did they actually somehow attach and keep EEG contacts on an animal that moves around and lives submerged in salt water? 'Cuz that sounds awesome.
In 2006, one Verizon store tried to charge me for tethering. Another confirmed that at that time, there was no extra ($19.99) charge for tethering.

I've been sent to credit agencies for bills I had paid on more than one occasion for the same paid bills and my accounts have been switched with other family members by Verizon on purpose taking over 20 calls and hours to resolve.

tl;dr: Verizon's service has always been shit. The FCC and our government need to step it up. Hard to do when you're in Verizon's pockets.

> Two other perfect examples of "obvious-in-retrospect" theories are evolution and special relativity. Admittedly, I don't know if the ancient Greeks, sitting around in their togas, could have figured out that these theories were true. But certainly -- certainly! -- they could've figured out that they were possibly true: that they're powerful principles that would've at least been on God's whiteboard when She was brainstorming the world.

Actually, people studying the Pre-socratics like to point out that Anaxagoras (IIRC) theorizes something eerily close to evolution: that at the beginning, there were all sorts of random creatures, and only the ones which did well survived and created more creatures like them. I don't know why noone followed up on it (in contrast to something like heliocentrism, where we know why the Greeks abandoned it for what were excellent and unobjectionable reasons at the time).

They seem to have missed the most important thing about accidental clicks: the position of the ad matters more than anything else.

If your ad is next to an important button you will get a higher CTR. If you advertise on a site that gets a lot of mobile visitors and your ad is next to an important button you will get a very high CTR.
Sorry, I still think it's customer stupidity. If you can't read "Samsung Galaxy Tab" printed on the box before shelling out a few hundred dollars, then I consider you stupid. Maybe we have different standards for what constitutes intelligence then.
Ruby also has the reputation of being much slower than Python, and speed is crucial in the scientific community when it comes to handling data-sets in the range of terabytes.

Edit: Also, when it comes to computer-technology the scientific community outside of CS generally lags far behind what CS is coming up with - for example, blastn, the most commonly used algorithm in biology for nucleotide-comparison, still doesn't have a proper 100% multithreaded solution.

There is also no adaption of NoSQL or any other of the "modern" data-storage solutions.

IMHO, this blog post only sees a narrow part of the picture, and gets it wrong.

To get anything done, we need to (1) have the desire, (2) turn this desire into action, and (3) continue the action and fight through barriers until we achieve what we want. "Just do it" works well as a mantra to turn the desire into action.

However, after this step, there is a whole lot more. How much natural ability do you have? How hard are you working? How much competition is there in the area? Are there political, legal, or other barriers in the way? There are many factors determining how far you will go. But, getting started is better than not getting started at all. This is an important step that is often not taken.

A more accurate way to put is is that "just do it" is necessary, but not sufficient.

I should say that I just wrote a blog post in the "just do it" camp so it may skew my views:

> In some cases, we may require you to change your password. (For example, if it’s commonly used or hasn’t been changed in a long time)

This is ambiguous...by "commonly used" do they mean 1) I'm logging in with my password frequently or 2) my password itself is a commonly used password? I'm assuming (and praying!) they mean the former since the latter would mean they're storing my password in plaintext.

UPDATE: Dropbox doesn't store in plaintext. I was incorrect to assume these were the only two possibilities. Confer child comments.

Quote from article: "When I want to make quick money on clicks," he said, "I just buy late-night impressions on women's gaming sites. I guess the users are tired. They click like crazy. I make a lot of money."

They wouldn't have to store your password in plaintext to determine that. They could just hash commonly used passwords and compare the hashes to yours.
I don't think this argument is analogous.

With a CATV subscription, you can hook up an essentially unlimited number of TVs. You could in theory watch every channel 24/7 for the same basic rate. The basic costs associated with cable are related to the infrastructure to bring the signal to your house, plus whatever licensing fees for content that are essentially passed through.

With Internet plans, we are charged repetitively for multiple devices, and in essence you are basically discouraged (throttling, excess usage fees) from actually using the service to 100% of the contracted rates over the billing period.

For example, I have on my account 2 iPhones with data plans (mine, wife's), 1 with tethering (mine), and 1 4G USB dongle. I went over the 5G limit on the dongle, but both of the basic data plans on the iPhones were under budget for the month, and I hardly used the tethering. Do you think I'll get a break from Verizon, or any kind of 'net usage' billing for the overage on the 4G dongle?

As others have pointed out in other threads, the mobile Internet space is ripe for disruption. It's not going to come from 2 college drop-outs on a $15,000 Y Combinator budget, but it's going to happen as soon as the economy lights up a little bit and we get some real infrastructure investment rolling.

You haven’t actually criticized any particular point of this article only stated how obvious it is and how other stuff is more important. OK, it may be obvious to you but this might be quite enlightening to other people especially those who have been fed on the kind of self-help bullshit the author is debunking. A lot of people are into that, sadly, and not smart enough--or perhaps too desperate--to understand why it is bullshit. If it’s so beyond you then just move on. If you want to enlighten us do it without making slurs against other people less fortunate than yourself.
What is a click? Is it just an indication of a person solving a little mystery along the route of his quest? Is it an experiment? Is it a nervous tick? Or all of the above?

Sometimes the window losses focus and I just click somewhere on the page so I can scroll again. Some pages are so dense that there is no place to click. And if they used white ads, on white sites that would look like empty space.
It wouldn't, necessarily -- I thought about this a little, and there are ways to identify commonly used passwords without storing them in plain text.

They could check passwords on login (before salting/hashing) against a blacklist of 'commonly used passwords'. This is probably the most secure method, as it only implies that users passwords are not on the blacklist, but does not imply plain text storage or unsalted hashes.

If they were not salting their hashes, then they could query their database for hashes that match the hashed version of commonly used passwords. Similar to the blacklist above, but implies that the passwords are stored unsalted, which is sad.
I read the order and press release (http://transition.fcc.gov/Daily_Releases/Daily_Business/2012... and http://transition.fcc.gov/Daily_Releases/Daily_Business/2012...) , and I don't see how it says what zdnet claims. What it really says is:

1. They can't block devices that offer free tethering

2. They can't block free tethering applications

This doesn't say "they can't charge for wi-fi tethering".

Just that they can't stop others from offering it for free.

In fact, it specifically allows them to continue to charge folks on unlimited usage plans for tethering (though folks can terminate that plan without a termination fee)

The zdnet quote that says verizon no longer charges is just a note in the order.
They will just check your password against a list of 'bad' passwords when you log in. No need to brute force the stored hash.
Dropbox Reports User Accounts Were Hijacked, Adds New Security Features
OpenVPN actually works very well with compression: used it for 2 years to synchronize databases between 2 sites in India and one on the US and the compression cut the sync time nearly in half. It was pretty much fire-and-forget: I think I only looked at it twice in the 2 years after I set it up, both times to replace certs. I'd use that over an ssh tunnel, if only because you wouldn't need the autossh tricks.
Your point is well taken, but it may still be necessary to know others - for example, I work at a large and well-known Internet company and we use Perforce =)

My sense is that if you can regularly acquire and store thousands of vintage LPs for less than $3 per record, it doesn't matter where you advertise the yard sale.

Why Plivo Cloud is better than Twilio
I'm curious who all received this email? Was it sent to the entire user base? If not, what selection criteria did they use?

Everyone I've talked to seems to have received the "reset your password" email. I'm quite curious because I'm certain (up until now) that the password I used for Dropbox was both (a) not commonly used and (b) had been changed recently and (c) not leaked anywhere else (to the best of my knowledge).
Case study! I've been getting mostly-painless migraines for maybe eight years now.

An area of my visual field stops reporting data. It doesn't look like anything, I just get no data. This is a relatively rare form of "aura"; most people who get aura report some kind of positive phenomenon. It starts as a few-degrees-wide field near my focal region; later in the cycle it gets bigger as it moved farther from the focus. I can only locate the region by moving my focal point and watching for bright objects to disappear. I discovered it when trying to figure out why reading was suddenly very difficult.

My blind-spot episodes last about 30 minutes. When I first started having them, there was no pain at all. Since then, they've started to be followed by mild headaches, and sometimes by a cognitive stupor. If you read up on migraines, that's consistent enough that I almost wonder if I've tricked myself into adding these symptoms psychosomatically.

More generally, I've met lots of people who have migraines who think they don't, because their headaches don't debilitate them. When they also report aura, I tell them to go look up "migraine".
Those inline tweets are grating. The overuse of lines to delineate related content looks visually noisy. I also think the top story is given way too much space. On my 1280 x 800 display, the new Digg shows me 2.5 stories. I'd like for them to use a tighter grid so they could fit 4-5 stories above the fold on lower resolution displays.
It'd be really nice if articles like this actually linked to the website for what they're talking about.

Ankit and Rahul are just good at talking themselves up. There are plenty of people in InfoSec that excel at marketing themselves.

Worst of all, they are an embarrassment to the intelligence agencies they have purportedly worked for.

I have no doubt in my mind that a graduate beginning her infosec career at the NSA, DSD, GCHQ, RAW, Mossad or other intelligence agency would show a better understanding of fundamental security concepts than these fuddiduddies.

Math Matters: A Response to “Is Algebra Necessary?”
I don't find the world's best athletes inspiring, precisely because they often benefit from quirks of their physiology that I don't share or training that dates back to their single-digit years, or both.

I do find athletes in technical sports like sailing, rock climbing, extreme-depth diving inspiring because those sports require a combination of physical ability and problem solving. Sailing is particularly inspiring because even the least able sailor is able to leverage some of the most powerful forces on earth to their advantage. But even Dennis Conner can't sail directly into the wind.

Getting back to the original post, I do find it useful as an engineer to attempt impossible things from time to time. Often the impossible is just inside our heads. Sometimes our expectations for our self are too low. But sometimes our egos are too big and we benefit from failing at something impossible too.

I _completely_ agree with you - and I wish Ouya had been a lot more humble about what they were trying to accomplish. Sure, they wouldn't have gotten $5mm+ in funding, but, at the same time, they would have had a much greater chance in delivering what they were trying to accomplish.

Heck, just having a controller working in 8 months would have been a huge victory, controller + API + console in 8 months is what I would have targeted. Six months after that a developer platform. Six months after that a Downloadable (free) store. Six months after that a Store-for-Pay. And Six-months after that some AAA games available, like Minecraft or FF7. These are realistic goals, and would have avoid the certain disappointment when in March, Ouya doesn't have Quality Console+Controller+Store+Free-Demos+AAA Games.

Which, alas, I guarantee you it really, really won't.
It's quite obvious from context that it's the latter. However, there is zero implication that they are storing passwords in plaintext. There are several ways to implement such a feature.

First, the password could be checked on login when it is sent in plaintext but not stored. Second, they could run an offline dictionary attack against the hashed password database.

I think they needed to take away the ability to comment.

Digg was a pretty awesome community in 2005 and 2006. The content was largely tech related and the comments were informative and interesting.

In 2007 it started getting worse, there were more jokes and memes and the content started to suffer. With no subreddit like system the original community began to become drowned out.

Towards the end of 2008 there was nothing left except memes and lame one line jokes that put youtube comments to shame. I was always surprised by all the people complaining about Digg v4 - the community sucked a long time before that.

I'm impressed by this revision, should be interesting to see what happens.
It's a /really/ good one too. Even I like it.
I think it does a great job of selling Instahero.

Also I think if you cut out the excess words you get down to even more concise, compelling reading.

So for example your bold headers span several lines. You could go from...

"You want to know the core metrics of your business at a glance"

to

"Core metrics in an instant"

Repeat with other headers too. Simplify = amplify :)

That's kind of my point. I think they saw what "hackers" did with it and saw the reactions and put two and two together. I think if they tossed the amp and opened it up as a Google TV like device, it would pair great with Fiber, Nexus 7 and would give them a Google TV device that is similar to their Nexus devices in terms of their level of control, etc.
And conversely so with Microsoft employees and similar criticisms. Nobody likes to the think they work for The Man or some kind of corporate tyrant, most truly believe they bringing value to the lives of their users as opposed to exploiting them (even incidentally).

Google is just as susceptible to trust issues as Microsoft or anyone else. Every time Google is caught violating privacy it's always an "accident", like with the wifi network data collection being done by their street view cars. If a company is constantly apologizing for "accidents" that align with their business interests I'd have a hard time trusting them, even if I continue to use them.
On the other hand high bandwidth prices slow down adoption, usage and evolution for all other industries which uses these telecom services. The rest of the economy is held back by these prices.

I would argue that the benefits of low bandwidth prices for the rest of the economy outweighs the benefits from the current telecom profits.
