I mean "rational" in terms of being able to justify it to others, and have it be rational to them too. I can convince the board why a moderate donation to Charity X is good PR, or why funding Product Y is a sound investment. It's much harder to justify why the company should give away half its profit with no direct return.

"... At 17, Franklin left Boston and started his own printing business In Philadelphia. At age 21, he formed a “club of mutual improvement” called the Junto. It was a grand scheme to gobble up knowledge. He invited working-class polymaths like himself who wanted to experiment in 1700s lifestyle design the chance to pool together their books and trade thoughts and knowledge of the world on a regular basis. They wrote and recited essays, held debates, and devised ways to acquire currency. ..."

Quantum Computer is 10^80 faster than a conventional computer
I had been doing web dev and marketing for years while working full time. I had a family and mortgage to support. But the time was right to go full-time consultant when I landed a client who was ambitious and had a lot of work for me.

This client also happened to be a "super-connector" who told everyone about me and how good I was, so that helped.

My advice: learn how to market and start planning now, be patient, ask God for help, and you will surely have your own business.

The reason your analogy breaks down is competition. Usually it's pretty easy to obtain food in some shape or form, so there are near endless alternatives if you face steep pricing. It's really quite difficult to be a competent doctor, so you've got limited alternatives. The magic you would need to apply is reducing the barrier to entry to medical competence somehow.

In general, I agree. In this specific case, I disagree.

I'll confidently bet that Instagram will be "integrated" or forgotten in a few years, relegated to the dustbin of ephemeral "one feature" companies that briefly caught on with hipsters before winning the startup lottery. Meanwhile, SpaceX will still be going strong, revolutionizing private space travel and space cargo delivery, and possibly have achieved tangible milestones toward the first manned voyage to Mars. One company is not much more than an iPhone camera app with a web backend for sharing, is cheap to do, and something that many thousands of developers could do well. The other is doing rocket science, costs hundreds of millions plus, and is staffed by a team of folks of a kind where few can do it well, if at all -- and especially, it now appears, also do cheaply. Humans had tons of pre-existing ways to share photos and "apply cool filters" before Instagram came along. Humanity has very few ways of getting into space (ie, rocket companies), and now SpaceX is one of them. And I respect the significance of democratizing media -- but I felt it was very well democratized in dozens of ways before & without Instagram.

And don't even get me started on Gmail. (kidding!)

I wold argue that "DoS" is not vague, just a broad term.

Aanyway.. You're right, it boils down to bandwidth flood (or maybe CPU..) in the end.

Maybe CoS is not really a technical term, just made more relevant by the technological changes. OP would have been charged much less had he not been using "the cloud".

Lets say I have small'ish competitor hosting their app on EC2. Using classical DoS techniques, how much can I ramp up their bill before they notice? Or can actually stop it? What if I run it on a smaller scale, "just" doubling their bandwidth bill.. Will they notice? Maybe they'll believe it's extra users ;)
Did webscale computing force Intel’s Cray buy?
It's just easy, intuitive, doesn't require any scaffolding, and gives you just the information you want, exactly as your program sees it, yet with the full power of the language to format it exactly as you want to see it, in the most useful way. A breakpoint will do the same thing sure, but only by stopping your program in its tracks! Dtrace is the only thing I've seen that is as useful as liberally sprinkled printf's.

A unit test will tell you if you know what output a function should give for a given input, that it does. Ermm, brilliant, but what if that function isn't on your code path anyway? And assuming that you already understand the program well enough to create any state the function expects if it's impure.

Actually most have never knowingly used computers outside the Windows sphere of influence but we shall let that pass. Unix was a massive breath of fresh air at the time, it became popular and widespread because it was so much better (and more accessible/cheaper) than commercial operating systems of the time.

The cultural bindfold you refer to is because there has been no comparable revolution in operating systems design since Unix, people tinker (comparatively) at the edges because Unix got so much right. NUL terminated strings is a minor aspect of library design. Yes with hindsight if things had been done differently then things might now be different, but like the QWERTY keyboard once decisions get out in the world they become too difficult to reverse.

I have two related ideas for a useless language, this is very close to the first one.

The first idea is that you normally use at least 2 symbols for a programming language, but you can in principle get away with just one. The "vanilla" form of this idea is to use the length of the processed string as the instruction itself -- that is, it has a bit pattern which gives you two symbols to play with in principle. Of course that's pretty ugly so you can instead do something slightly more "advanced" and use a non-character as a delimiter; the most obvious choice is file boundaries on a filesystem, but in principle any data structure boundary can be used.

The second useless language that I want to create is one which I'm not even completely sure works. The idea is that you have some number of nodes -- let's say 256 -- which each contain some number of bytes -- let's say 4. Those bytes represent two (node pointer, instruction) tuples. These get initialized to a definite 1KB prelude, and the computer starts at node 0. The instructions can also manipulate registers and a much larger memory space, and can load ints from that memory into other nodes, but the 1 KB is needed for the interpreter.

The idea for this useless language is that, the computer chooses one of the two tuples randomly, performs its instruction, and then goes to the node it points to. >:D

The basic idea is that all esoteric languages seem to be about "how do you program familiar thing X if you don't have Y?", but I have 256 instructions so I'll give you all sorts of wonderful functions to call on your registers. The problem is really just that the computer does not natively want to follow a deterministic path, and you have to "herd it" into that mentality.

That FDA regulation sounds reasonable. (If it is a regulation, maybe the guy on the phone just wants to get rid of the caller.)

There are restrictions on who can practice medicine, and there are restrictions on what medical products people can buy and use, so it's reasonable to think that there will be restrictions on the suppliers about what they provide and who they provide it to.

The heavy regulation is not preventing competition. The heavy regulation is just providing a minimum base for that competition. The problem is with the utterly broken system of US healthcare.

Note that in the UK you still wouldn't get any information about hacking your CPAP machine. And you'd go to a doctor, who'd refer you to a specialist for sleep trials and fitting. And you'd have to try "lifestyle changes" (losing weight) first.
Please stop using the word epidemic in this way. Especially for a medical condition which is not contagious. I know what you mean but the wording makes it sound you can get obese by being around obese people. Thats tabloid vocabulary at best.

For people with Android phones, check out Orbot - https://guardianproject.info/apps/orbot/ - It's Tor for Android. It's an incredibly well polished app. If you have root, it will let you individually and transparently torify any app. If you don't have root, individual app will need to support socks proxies in order to go through Tor.

It supports bridges, and it will even let you run a relay and/or hidden service directly from your phone.

I've had this idea for a while now of building an SMS-like app that runs entirely over hidden services for users with Orbot installed. If I send you a message this way, nobody knows that you received one, that I sent one, or what the message contained, and it wouldn't require me to set up any server infrastructure as it would be entirely peer to peer over Tor.

It's a funny joke. I had similar thought about "Backstreet dentists" in the UK. A few years ago there was a problem getting NHS dentists, and many people didn't have any insurance. You could have made money by trafficking East European dentists into the UK and setting up a secret dentist.

> Can you tell me how you reduced your fructose consumption? What foods did you eliminate and what did you replace them with?

Basically I stopped adding honey to my coffee (sad - it's delicious) and cut my fruit intake from 10-15 pieces to 2 per day. Also I eliminated all other sources of sugar such as cake, though these had been pretty minor in my case anyway.

I agree with Lustig that fruit is less toxic than concentrated sucrose or HFCS, but I am living proof that in sufficient quantities it is still bad news.

I added some extra fats (nuts, flax oil) and some extra protein (beans, peas, fish, red meat, chicken).

The best thing about the weight loss is that I lost weight in the bad places (ie my stomach) which previously had been impossible to move.
For USB devices, where you have access to both the device and some proprietary software that can drive it, this isn't so difficult: you can intercept the USB commands quite easily, then it's a matter of spotting patterns for each activity.

For intercepting the USB traffic, you have a few options:

- software USB Snooping; this hooks into your OS's USB subsystem and intercepts data. The Linux USB debug stuff works well for this, I've had less luck on Windows.

- using a virtual machine and forwarding it the USB device. I've had success with this for intercepting the USB traffic for a device with only proprietary Windows drivers, but where snooping in Windows directly failed. Boot up in Linux, set up a Windows virtual machine, forward the USB device to the VM, install the Windows drivers in the VM and use Linux' USB debug interface.

- Hardware USB snooping devices. You physically insert them between your USB device and the PC, and they log the data flowing through. Obviously, this is a bit more expensive, but will basically always work.
This is great - Dropbox are doing only one thing and they're great at it. The way I see it it's like Google is a restaurant that sells Italian and Mexican, and Dropbox is just Italian - where would you go to eat?

And with the competition, Dropbox will focus more on monetizing enterprise users and in order to keep the individual users it will at least match the space that Google is offering.. So as far as I am concerned I am getting an Italian chef to cook my meal for the price of McDonald's..

How I Tricked Myself Into Being Awesome
Huawei Honor U8860 features and price in India.
At simulating the quantum mechanics of simple 2D spin systems, from what I gather from the Nature article.

The press release sounds like they've developed a quantum computer, but this is not borne out by that article. While there is lots of promising work in quantum computing as a whole, this as I understand it can't be used for that, because you can't tune the qubit interactions individually but you can only tell the whole lot to do the same thing. (At least, the abstract doesn't seem to discuss anything more complicated than giving them all a ferromagnetic or antiferromagnetic coupling.)

If that's correct, then this article seems overstated. At the very least, I know there are now "optical lattices" of qubits made from atoms supercooled into a Bose-Einstein condensate and then relaxed into a very pure square lattice. You don't have to know what that means, just know that with some method which is now reasonably well known, you can get much much more than 300 atoms interacting via quantum mechanics. Like, optical lattices get hundreds of thousands, if my memory serves me correctly. So this isn't, like, the biggest entangled system ever demonstrated of this form -- not by far. It might be the biggest which has this level of tunable Ising interaction, that I don't know. But there are now tons of approaches to quantum computing, and yes, some of them can throw much larger numbers at the problem than just 300.

The very nice thing here seems to be the quantum entanglements getting done over a spacing of 30 microns. That might not mean much to you, but the optical lattice work is done at tiny spacings, and it becomes extremely difficult to do any sort of individual readout. 30 microns means that you have a lot of leverage to address individual atoms. If you could get them all to entangle with each other and then you could manipulate them individually with some gates, you might be able to get some good quantum error correction set up.

That probably also doesn't mean anything to you. The important fact about quantum error correction is this: once your QEC is reliably set up, you have passed the critical barrier and you can scale up arbitrarily to a quantum computer by just throwing more atoms at the problem.
I totally disagree with your last statement. Google Search, GMail, Google Analytics are all examples of great user experience (although I don't like GMail's redesign). To most people Dropbox is just a folder where they can put files that need to access from different places/devices, so I am a bit skeptic regarding the value of Dropbox "experience know-how". With more space, Google Docs integration and probably GMail and G+ integration as well, DB should at least be worried.
