Better is to use random data but even so you still have forensic techniques to revert this.

How does one revert this without physical access to the drive?

We overwrite our EBS volumes with zeros before deleting them and I was under the impression that should protect us against leakage to other customers.

Naturally it can't protect us against a malicious amazon employee pulling the drive physically (or taking snapshots without our knowledge), but frankly I don't see how your "vendor encryption" helps with that either.

If all I do is set a checkbox to "mark the drive for encryption" then that means

a) You have the encryption key, I don't.
b) The checkbox could just as well be a placebo and not have any effect.

Thus we're back to square 1 and the same old question: "Do I trust you?"

No need to take a 10%-15% performance hit for that.

I don't understand the constant assumption that if you choose to study in your spare time, you have no life.

Maybe I run into the wrong people, but I've not run into this assumption much (outside of college where kids don't know much about life anyways).If someone chooses to study, be engaged in their domain outside of work, have 'intellectual' hobbies, that's usually a plus in my book.

I'm curious where people have run into this?

I think this goes triple for mathematics. When people say that I'm good at math, I sometimes tell them, "Well, you know, I've been studying math and little else for the majority of the past ten years. Almost anyone who works at something that long eventually gets the hang of it."
Really? I've never read American bar although I heard it leaves a lot of common drinks out on the grounds that Schumann didn't like them. I'd also find it strange that you'd limit yourself to drinks prepared for a mock-American bar in Munich.

If you're going to limit what you do, doesn't it makes more sense to limit the menu to IBA cocktails? (I don't know, never ran a bar, know a few who do though).

Also why the Claridge recommendation? Any particular reason? I'm interested to know.

This is correct. I assure you that the physics texts all tend to use i and j as index variables. Particularly for matrices, whose terms have a tendency to be written as M_i_j. [1]

No, it doesn't. But you're implying that a small step in the right direction is pointless because we have no idea how to engineer a complete solution. I don't agree - trust is a known, hard problem and the best solutions (think about ssh) are very pragmatic about it.

I worked on a project like this a while back. The heavy regulations eventually broke the whole concept. We had built a system for startups to pitch their businesses, and the investors would have been limited to accredited investors (those with > $1M or who make > $200K/year for two years). They would have bid for startups in a Dutch auction format, like the way Google went public.

However, to do this you need to be not just a startup, but an NASD certified "broker dealer." This imposes a couple things that software startups aren't good at:

1. You need $500K in the bank, just because of regulations. This means you need to raise much more than usual.

2. Several founders/early employees need to study for and pass Series 7 exams, which is what you need if you're a stockbroker. At least one person also needs to study for a similar test for brokerage management. Coding + learning to be a stock brokerage was not easy!

3. The associated legal costs were extremely high.

Kickstarter of course avoids all this by not dealing with any transfer of ownership so they don't need to worry about the government. They just sell access to creative folks, which is a good idea.

PS - Angel investors and VCs hate this concept, which makes it much harder to raise money. We brought it in front of all the biggies and were well connected, and each one argued about the personal value of their involvement, which may or may not be true.
More specifically, I think the N stands for "Natural number".
But there are many problems that information sharing just can't solve. Let's take African village X, imbue the population with a shared desire to break free of their government bondage, and give them a very poor infrastructure. Once they stop celebrating their defeat of the government, they're going to have to face issues such as who gets how much water. These things can't be solved by the Internet, and this is basically my original point about competing for resources.

I'd also take issue with the idea of the middle class being allied to the poor. Doesn't seem to work that way in the U.S., at least.

Don't get me wrong - I wish you were right. A more fair and equal world would undoubtedly be a better place, but I think the probability of that occurring anytime soon is pretty slim. Even if you solve issues like famine, medicine and economic development (which is a pretty gigantic if), something new will take their place as a focal point for competition.

EDIT: We could argue this til the cows come home. I think it just comes down to your optimistic view versus my pessimistic view. Only time will tell who's right.

I think natural talent exists, and it manifests itself as an ability to know where to direct your focus when learning something new. Someone who lives in their head a lot may fare better at programming initially, for example. They're used to talking through things in their head.

But eventually the natural talent can't carry you any farther.

I guess in order, my top 5 favourite vodkas are:

1. Potocki (Polish)

2. Żubrówka (Polish)

3. Wyborowa (Polish)

4. A home-brewed vodka from a Ukrainian friend's still near Moscow.

5. Snow Queen (Kazakhstan)

I can't believe that poles of all people would drink Finlandia when there's things like Potocki around. Mind you, in the UK we have amazing ales and people drink things like Stella Artois and Carling.

You raise a number of interesting points.

Firstly we can't comment on the arrangements of other companies for whom we don't have visibility. As a customer you can of course ask them and one would hope they are able to provide you with a full answer. On the blog we raise and answer (in our case) the various aspects for data storage, not just of security but also legal issues and data migration aspects. How many customers currently using an IaaS cloud can answer those questions or get their vendor to provide answers? Building confidence in cloud computing is all about transparency, education and creating secure ways of working. Different users will choose different solutions and regimes that they feel are 'secure' for them and we are all for that. We'd also like people to be able to make informed choices which means having the right information.

Secondly, there is a big difference between a vendor that has sole root access and full visibility of all your data and one that doesn't (as in our case); in our cloud the customer retains sole root access to cloud servers. This means our employees don't have visibility into cloud servers in the way you suggest. Further, as clearly stated in the blog, the issue raised is about data leakage i.e. data being accessible between cloud users. There are other issues regarding vendor security but this doesn't negate the points being made about data leakage.

Finally, your point regarding the encryption being a placebo is specious. There is a big difference between making systems secure against casual data theft/leakage or the actions of rogue employees and a company that is institutionally set up to lie and steal their customers' data. If you think your vendor is actually of that nature then no security measure can help and that's the case for any company you have dealings with. It really isn't a valid criticism of any security measure that may be put in place.

The measures we outline and have implemented on the vendor side do address the real issue of data leakage that occurs with block storage devices in IaaS clouds; they are effective and they are convenient. Our storage performance is generally higher than many other vendors to begin with and we have much feedback from customers regarding this even after using encryption. These customers are getting good performance in a secured cloud. For them it makes sense.

Best wishes,

Patrick
i, j, and k come from Hamilton's Quaternions.

Euler picked i for the imaginary unit.

Hamilton needed two more square roots of -1:

ii = jj = kk = ijk = -1

Hamilton was really influential, and quaternions were the standard way to do 3D analysis before 1900. By then, mathematicians were used to thinking of (ijk) as a matched set.

Vector calculus replaced quaternionic analysis in the 1890s because it was a better way to write Maxwell's equations. But people tended to write vector quantities as like this: (3i-2j+k) instead of: (3,-2,1). So (ijk) became the standard basis vectors in R^3.

Finally, physicists started using group theory to describe symmetries in systems of differential equations. So (ijk) started to connote "vectors that get swapped around by permutation groups," then drifted towards "index-like things that take on all possible values in some specified set," which is basically what they mean in a for loop.

I've been making this argument for years, its funny how many people just flat out dont agree with it. My stance is that there is no talent, just understanding and without physical limitations, anything could be understood by anyone.

I first came to this conclusion in art class when I was about 15. A girl asked me to draw a traffic light for her (I am a pretty decent artist) and I said no, but explained how to do it and she did a pretty damn good job at it.

I feel that if you ask anyone who is talented at anything, they may have to border having a passion for it, they'll be able to explain the how to you.

I tell my son this very thing and I feel that he approaches problems differently than if I told him "oh, that's a god-given talent, I dont know if you can do it."

Yes, a LOT of success comes from effort, but to say that talent doesn't exist is absurd. People who have a talent in a given field, AND work with and hone that talent will always do better than people without talents that try to get into a field they aren't fit for.

There is some truth to what you say, judofyr, but talent is real. The problem is, the only way to find if you have talent is to put in a ton of hours. Sometimes talent shows up later in the learning process.

"You will look around and find other people at your age who are way better than you at playing guitar, skating or singing. How can you possibly be as good as them? They must have a talent for it! But in reality, all they did was starting earlier than you or have been spending more time doing it."

Hogwash. I started singing and playing guitar at the same time as some friends of mine. We spent the same amount of time - if anything, I probably spent more time than they did. They got better. I didn't - well, not to the same degree as they did (I'm not bad but nowhere near what some of them can do).
For a long time I've wanted one of these, to serve as an "interruptility" indicator to others: green = "I'm looking at the internet, please interrupt me so I can possibly do something more useful", amber = "I'm working but okay", red = "only interrupt me if it's truly urgent". It could be programmable, so that (for example) it could automatically go to green when Firefox had HN as its frontmost window.

Imagine a lab or office in which everyone used an LED in this way. It might be nice.
We just hired 2 engineers on an H1B. It's expensive and complicated, but for important hires it's worth it. And in a startup every hire can mean life or death.

An important caveat: H1B allows ZERO flexibility in the equity/cash mix. You must offer market salary or the visa will be denied. Immigration ignores equity entirely.

I think that for me this only makes sense for projects that have no explicit deadline. For a procrastinator, a deadline is the only thing that matters. I can block off all the time that I want to for a project, but if my brain is in procrastination mode, virtually nothing productive will get done.

Early on, I imagine that guilt about doing nothing during the creative blocks would motivate me. Over time, I suspect whether anything got done would roughly break down based on whether there is an explicit deadline. With no explicit deadline it would depend on how excited I was about a specific creative project.

If you're doing creative work for a living, I don't think that you can assume deadlines away.
This viewpoint always annoys me. It's great to think that work is all there is to it, but that's not true.

You can become great at anything with practice, I do believe that.

What I don't believe is that there's no such thing as talent. Take chess. You really think Magnus Carlsen has practiced less in his life than Anand? Practice is necessary to become great. Talent is necessary to become the best.
I particularly like Fleming being prescribed bourbon to cut back on his gin consumption.
Our post is regarding IaaS clouds in general and has nothing specifically to do with EC2 or any other particular vendor. It may be the case that EC2 does have secure measures in place; I wonder how many of their customers can articulate them (or customers of other IaaS clouds for that matter)? We are merely raising an important issue. You can look at the many other posts we have on the other various aspects of security in the cloud of which this post forms the latest instalment regarding data storage.

"there are more efficient ways than encryption or "full sweep overwrite" to address this at the storage-level."

Your suggestion would be?

Reasons Groupon's Rejection Is Great For Us
Here's a trick that works for me:

I've noticed that creative ideas often pop in at random times when I'm doing something unrelated to the idea. So I created a little script that, upon hitting the F10 key, opens a dialog. I type in my thought and it writes it to a file called jot.txt. At the end of the day, I review jot.txt and act on the ideas. This allows me to capture interesting ideas when they happen without losing my current train of thought.

If you're interested in adapting this script for your own use, I've published the script here: http://techiferous.com/2009/12/streamlining-your-workflow-wi...
'Unlike computer science there isn't a question of "do I need to work on medicine to continue to be on the top of my game?" The answer is yes. Period.'

Perhaps the difference there is, who wants to go to a physician not at the top of their game for anything beyond a routine physical? Whereas a programmer not at the top of their game can do some useful things and won't kill anyone barring exceptional circumstances.

In a competitive world, if you want to be on top in any skilled discipline you are going to have to put the time in. My family is primarily auto-related, and while they may not spend every spare hour tinkering with cars in their 50s, they can still do it and have certainly booked many thousands of hours not at work doing it. That industry supports even more people who don't really care.

Yes, but according to my experience, this essay is incorrect in assuming that talent doesn't matter [1].

So if you really want to be more precise:

results = talent x effort x time

Which means, talent is multiplier. If you take multiple people with different amounts of talent, let them work for equal amount of time on something with equal intensity and focus, you will get very different results.
