1. Database credentials are encrypted on the disk so they're harder to capture than reading off crontab.
2. The dump is compressed using gzip, which saves a surprising amount of space and bandwidth.
3. The dump is encrypted using a random passphrase each time with AES-256, then the passphrase is encrypted with RSA. The larger dump file is encrypted more efficiently and more quickly using the symmetrical cipher, while the 30-char passphrase is secured using the same strong pgp cryptography. Since the backups are all encrypted using a different key, it's harder to compute keys if given the encrypted data files.
4. It's decently tricky to get Dropbox running well on linux machines via CLI, and you can store more than 100 GB without contacting us for storage expansion.

What do people think of Meg Whitman's record at eBay?

From her Wikipedia page: During her ten years with the company she oversaw expansion from 30 employees and $4 million in annual revenue to more than 15,000 employees and $8 billion in annual revenue. [1]

Seems pretty impressive to me. It's also easy to forget how many companies tried and failed in this space, including the likes of Yahoo.

"How much would you pay for a tool that made you aware of updates in the open source software that you built your product on?"

Well first as you know peoples answers to this type of question is filled with false positives.

I think your service needs to be sold on an enterprise level to people who have a budget and can pay for it. People who use open source but also pay for and have the budget for solutions to problems.
This pattern is sometimes called an intrusive data structure. For example, see boost::intrusive in the C++ world. It saves allocation, gives better locality, and allows various optimizations such as the ability to remove an object from a doubly-linked list in constant time.

Another way to think about all the offsetof() stuff is that it's emulating multiple inheritance in C. You can think of structures as inheriting the "trait" of being a participant in a container; the "pointer-arithmetic-and-cast" idiom to move from a container entry to the corresponding object is isomorphic to downcasting from the trait to the object that contains it.

Interestingly it is not possible to express this pattern in a generic way within Java's type system.
Wow..... this is capital news! There is a flaw in our whole comprehension of physics and our basic understanding of everything that surrounds us. There might be faster that the fastest we have ever imagined and based our calculations on.

Yet, we see news like "Kardashian hubby's bad first impression" on the first page of sites like Yahoo "news", disappointing...
Yeah, I know what you mean.

I'm not too concerned about costs/add revenue at the moment. The server is relatively cheap, and used for other apps anyway.

I haven't even yet bothered to put up ads on the page - because I know the revenue off them is going to be pretty close to zero, and it means going back and trying to fit the ads on the page in way that doesn't look terrible.

My main goal for this was to actually start a project, finish it and actually get some users. I've managed to achieve this (in a small way) at least.

It was pretty discouraging to fail to get anywhere with the last few projects I attempted, so at the very least getting to this stage with dudmail.com should carry over into some motivation for the next attempt.

(And I'm sure whatever my next project is, it will be the one that makes me rich and famous =)
This is changing. As people who grew up with the internet start to become responsible for spending, salespeople are figuring out that "no price = no lead". It's a slow process, I'd say it's got another 10 years of steam left in it, as the old guard (on both sides of the table) fade out, but I hear this concept being discussed from business/sales/MBA people far more today than 10 years ago.

> The delay between the time that the atom absorbs the photon and the excited atom releases as photon causes it to appear that light is slowing down.

If the photon is traveling less D over the same amount of T, I am ok with saying the velocity is lower, and it has slowed down.
Well Hellen Blavatsky was right after all; Science must finnally accept not just the existence of matter but of Spirit as well.

Besides scientific calculation of speed is based on the assumption that the velocities of transmission of all the colors are the same. Namely, if we call "W" length of the wave of any given color in ether, and "V" the velocity of transmission of that color, and "N" number of vibrations or waves of that color per unit of time, then the formula connecting these is W = V/N. But in order to calculate the rates of vibration Science assumes that the various Vs of the different colors are all equal to one another. This assumption is false and it has been proven that the velocity of red and of blue light are different.This is an important phase in human History-If this is true then the age of the Stars has Just Began.

The web needs artists, not owners. People who work on the web today are mostly either techies or static visual designers. We need to take those skills and figure out how to harness them to create better final experiences.

Consider computer animation. At first, most of the people who used it were techies or traditional animators. But computer animation was a new medium, and its first success came when Pixar took their technical and aesthetic skill and made them subservient to storytelling. In the process they discovered that voices and music were as important as the company's "core competencies."

The reason that 280 Slides and iCloud blow people away is because they take things which are known to be possible technically and aesthetically, but they make those skills subservient to an overall interactive vision that borders on art.

I.e., if I use MOG and you use Spotify, we don't get the social features.

I'm not sure I understand the point of this article. Do things differently? What an original article.

What the article fails to mention is the thousands of startups and companies that tried to do things differently and failed. I think Steve Jobs took a huge risk, and he had the ability to pull it off, and he succeeded. Not everyone can do that. So many things could have gone wrong for someone else.

He's not creating a false dichotomy to attack--he's responding to Joel Spoelsky's post, and Spoelsky creates a very clear dichotomy of smart and not-smart in his post

"I've seen that the 100% Java schools have started churning out quite a few CS graduates who are simply not smart enough to work as programmers on anything more sophisticated than Yet Another Java Accounting Application, although they did manage to squeak through the newly-dumbed-down coursework...I used to be able to tell the smart kids because they could rip through a recursive algorithm in seconds, or implement linked-list manipulation functions using pointers as fast as they could write on the whiteboard. But with a JavaSchool Grad, I can't tell if they're struggling with these problems because they are undereducated or if they're struggling with these problems because they don't actually have that special part of the brain that they're going to need to do great programming work.

I was interested in the two times he used the word "lucky."

The first time he used it to indicate he wasn't lucky (less than 10% of downloaders using Color), the second time to indicate that they could change the way facebook users interact (if the app is a success). I felt it was odd to see him use it both positively and negatively in a few paragraphs, and think it may indicate that he's not confident in this latest pivot (the first use felt more true).
Also:

>Mr. Nguyen, who described himself as a “social recluse,” said that he realized that Color needed to be more engaging and more social to lure in new users who would find it rewarding.

Facebook wouldn't have been a success if its creator hadn't released it while he was in college. It's hard to imagine Color, in its ambitious proximity-based plan, ever being successful with a CEO who doesn't get out.

Elements to Remember in Web Site Design

1.) The database credentials must be stored somewhere in a reversible format in order for your script to connect to the database to do the dump?

2.) Could just add an extra "|gzip|" inbetween the mysqldump and gpg commands in the example I provided.

3.) I think this is how gpg works internally. Generates a symmetric key, encrypts that with the public key, and then encrypts the actual data with the symmetric key. This is why you can encrypt a file for two recipients without it doubling the size of the resulting encrypted file.

4.) I do remember having some minor problems when setting it up, but it was quite a while ago. Not a show stopper though.
This statement kind of baffles me:

"A neutrino burst was observed in 3 different labs about 3 hours before the light was observed. If neutrinos are capable of traveling .0025% faster than the speed of light then why would we observe these neutrinos at a time that is consistent with them traveling at almost exactly the speed of light (slightly less due to their finite mass)?"

Wouldn't this mean that neutrinos DID travel faster than light, since they got here faster? Could the time difference (3 hours versus 4 years) be accounted for in the fact that they do travel slower due to their finite mass, as you pointed out?

Also, if indeed it is a difference of 4 years between when observatories detect neutrinos and when the light gets here, wouldn't it be really, really difficult to correlate one event with the other? In other words, we would probably not be able to prove that a neutrino burst belongs to a particular visible supernova?

(p.s. I'm not an astrophysicist - am I overlooking something obvious?)

Facebook’s revamped OS-in-the-cloud is worst news for Microsoft
As I interpreted it, the critical part of his explanation is the fact that the higher density part shifted from the back to the front. If that change in density would be due to actual photons shifting that way, then those photons would have traveled faster than light (whereas the entire 'blob', on average, traveled exactly at the speed of light).

I didn't watch the Keynote, but based on Nicholas Felton's feature on the timeline page and what I've read, Facebook gave him a lot of credit.

For those who don't know, Felton is a graphic designer hired in April [http://www.fastcodesign.com/1663718/facebook-hires-infograph... for more info].

The simple graphical layout of Timeline in the preview page reminds me of MySpace. But given how Felton is a big part of this. Facebook's designs have largely ebbed and flowed, but this looks like a cool concept and Felton's involvement has me excited.
If you tell someone that a simple concept is difficult, they will have trouble understanding it. I have seen this firsthand many, many times.
Well, the point is that there was a neutrino burst coincident with SN87a. So if there was one 4yr earlier, too, then you'd have to explain how the same event produced two bursts of neutrinos with different speeds, while within the burst they apparently had exactly the same speed.

If neutrinos have mass, they can travel at any speed <c depending on their energy, like any other massive particle. Of course, the upper mass limit is quite low, so even with very little energy they will go very fast.

(Edit: In fact, the arrival interval of those neutrinos puts an upper limit on the neutrino mass, because the larger the mass, the more different the speed and the more dispersed the arrival of them at Earth.)

I learned to use them long before I had any clue what a DFA was or had even heard of an accepting state. It was pretty intuitive to me that you just have to specify these patterns and it would match whatever you told it to.

When I later read more about the theory and how they were constructed in a compiler book, I wouldn't have been able to decipher a word of it if I hadn't already known how they were supposed to work.

I wonder why more books don't show you what they do before showing you how they're made.

If you're going for reliability, exceptions are generally speaking more unpredictable than error codes at the function level (as they can propagate up, including out of libraries, where you may not know they'll originate from).

Yes, you are right. Actually, it's just the bootloader. So, technically Microsoft can come up with a bootloader (GPLed) that can boot Linux or modify the current one. My bad!
