Deduplication and chunking. They break files into 2MB chunks and then shove those chunks into S3. How many unique chunks does it take to represent all of the data they're syncing? Not sure, but the math shouldn't be too hard to do if so inclined.
Example: Grab a very popular torrented file; throw it in your Dropbox directory (make sure its a big file, 500MB+). Watch how it goes from hashing to synced in under 5-10 seconds. Dropbox hashed it, notes it already has a copy, and tells your box not to sync it up ("already have a copy brah!"). This is the beauty of their business model. The curse? Anyone can do what Dropbox does; it is not magic, it just takes the resources and time to do it.
THIS. Backblaze? Their own datacenter (well, a datacenter in SF where they built their own gear). SpiderOak (and Nimbus.Io, a subsidiary about to do S3-style storage with higher latency but to be used for archival purposes)? Their own datacenter. Apple? Google? Of course, their own datacenters.
S3 is GREAT to prototype your concept. But once you start to actually *use* it and scale out wildly? Not so much (from a cost perspective; from the tech side, it works very well).
Only 4% of Dropbox users pay for their service, and Dropbox is already highly profitable. I would take that almost as a guarantee that storage prices for Dropbox-like services will be driven down if they're *that* profitable with so few paying clients.
Ok, so the reason Dropbox doesn't do encryption? It would break their model. They leverage the fact that they only need to store a file once across their entire platform (AWS S3), but can "charge" multiple people for that space utilization. Encryption would break this de-duplication ability, and hence cost Dropbox more money in S3 storage costs.
So what you're saying is its easier to work at the office because you can get constantly interrupted by someone in person?
As someone who telecommutes a few days a week, I'm much more productive at home without a) a commute and b) without someone coming to me in person to address something that could've been addressed over the phone or via email.
It is disingenuous to believe that "being there" makes you more effective. It only increases the possibility of someone interrupting your productive streaks.
Or the copper contacts have small plastic lips/edges on the battery/phone contacts, so they're watertight enough when the battery is seated (held in with the battery tension).
It equalizes prices to take into account disparities in regulation. Do we use child labor in the US? Of course not. So why should products or services marketed to those in the US get to take advantage of this "strategic advantage"?
Tariffs properly price and resolve economic externalities.
Same experience with our Hybrid Camry. Oil change and tire rotation every 5K miles, and we just rolled over 90K miles. Original brake pads are still on the car, although we did have to replace the water pump due to a leak about 5K miles ago. Very satisfied, although our next vehicle is a Tesla Model S.
"At issue here to is a sense of trust on the part of the government towards its citizens. A government which trusts its citizens to do the right thing is by far more likely to give you personal liberties and stay out of your life than a government which wants to monitor every detail in your life and protect you from yourself. Are you sure you want a government sticking its nose into your business, telling you how to live your life?"
Unfortunately, from what I've seen, most people are fucking morons. And yes, I'm OK with the government charging me more to smoke, drink, and eat shitty food if they're going to provide healthcare. I'm OK with the government charging more for fuel and coal-generated power due to their externalities. Your rights end where the next person's right's begin, and that includes the water and air you pollute for someone else, as well as the costs you shove onto someone else.
It's always "personal liberties" when it's your rights, and not someone else's rights.
"Road damage rises steeply with axle weight, and is estimated "as a rule of thumb... for reasonably strong pavement surfaces" to be proportional to the fourth power of the axle weight. This means that doubling the axle weight will increase road damage (2x2x2x2)=16 times.[1][2] For this reason trucks with a high axle weight are heavily taxed in most countries."
You're a god damn moron. "Distance" is not essential for safety. Materials that will deform to absorb energy in a collision is what increases safety. Do you think they put foam insulation under the hood? No. They use metals in specific shapes and configurations that rapidly absorb energy during accident-caused decelerations. Stronger metals (magnesium, for instance) that are at the same time lighter are also utilized.
You *do not* need to sacrifice safety to increase fuel economy.
I don't date anymore (married), but since I'm 29, I'd only date girls between 21-35, whom I've found to still appreciate Mr. Smith's style. As always, YMMV.
Thanks for your post. I think it adds greatly to the conversation.
I'd like to ask an awkward question, and I ask only in the most informational of ways. If it were to help you lead a better life, would you have your right leg amputated and replaced with a prosthesis (simliar to the one in this image: http://rehab.ucla.edu/images/P/prosthetic-leg.jpg)?
Again, I don't think you're lazy, etc. Its clear your reduced mobility is caused by your accident. I'm just interested in your prospective.
Thanks for your time. - Someone moving from IT into biomedical engineering.
Not sure what girls *you* date, but I've never had a girl turn down "Hey, I have a huge collection of indie, comedy, and Kevin Smith flicks. Want to come hang out?"
I'm only 29 though, so perhaps different generational feelings towards that sort of situation.
Are you insinuating that you should provide free labor because it would look good to a future employer? Fuck. That.
You *do* deserve to be paid for time spent writing something if its on your own time; you don't give it away from free unless *you* want to.
I wonder how many unemployed IT folks are screaming at their monitor while reading this article?
Only the ones who aren't any good and therefore have no mobility and aren't in demand. The rest of us? Cleaning up shop (and still making six figures in a recession).

2MB is the smallest chunk Dropbox will hash.
This is nothing new. You know who got rich during the Western US gold rush? Those who sold the tools, not those prospecting.

It takes a certain amount of energy to fight wind resistance no matter what at highway speeds; hybrids get the regeneration advantage.
The CRZ would be perfect (as a two seater) if it used Toyota's hybrid system with a 3-4 cylinder engine.
The latest V3 Prius gets between 50-60 miles per gallon of gasoline, the same distance you're getting on a gallon of diesel containing more energy.

Original brake pads are still on the car, although we did have to replace the water pump due to a leak about 5K miles ago. Very satisfied, although our next vehicle is a Tesla Model S.
When I'm doing 80mph on the highway in my wife's 2008 Camry Hybrid, I routinely get upwards of 40-50mpg.
