Dropbox's success depends on OS' file system representation. It's currently the perfect solution for the folder/file system but new systems like iOS and Android don't need a dropbox. I remember reading that Steve Jobs wanted to abstract out the folder/file representation for a simpler and easier to use iOS. They hide the files inside each app and it is all synchronized by iCloud. Dropbox clearly is aware of this paradigm shift and that's why they are pushing their new SDK and have a conference to promote Dropbox integration with any other apps.
I feel like I'm missing something obvious here, but how do I actually get this?
Oh come on, the ray tracer was really neat.
Please see http://cananian.livejournal.com/68747.html and https://github.com/cscott/rusty-turtle.

Yes, the post is brief since it was written from notes several months after I had been talking to the rust guys. I couldn't justify the time to spend making the examples more concrete (and wasn't exactly encouraged to do so at the time). Sorry, that is as far as I've carried the load, you've got to take it from here.
I think so, and OS X allows you to turn that off. Maybe the headline should be "If you care about privacy, check your mail client settings"?

Using 10.9 with "display remote images" disabled, I asked https://emailprivacytester.com/ to send me a test message. The test page indicators didn't budge when I opened the test message. Then I clicked on "load remote images" and naturally quite a few turned red. But that's why I disabled that feature in the first place.
Obviously I have nothing to go on for this, but just guessing, it would seem to make sense that:

- Of all users, only a small subset would have private repos

- Of those users, only a small subset would have private repos that would be of interest to third parties

- Of those users, only a small subset would have a weak enough password to allow brute force

To reverse it, of these accounts that were hacked, I can't see many of them having private repos that would be of interest.

And if so, then this would seem a bit excessive.

I know that's a lot of ifs, but it seems reasonable. I would be interested to see the number of total accounts vs. the number of accounts w/ private repos.
My understanding of the Riemann Hypothesis is that it can be reformulated as a statement about prime density. If this result is a concrete outer bound on density, does it have implications on RH?

In proper email and webmail clients, it's off by default and there's a button to 'display images' at the top of the email when you're reading it. Thunderbird, Android's built-in email client, Gmail, etc all do this.
Stupid Things Finance People Say
https://emailprivacytester.com/ is great. They'll send you an email with dozens of tests to determine what kind of information your mail client (MUA) is leaking to senders.

I use mutt exclusively and of course it's perfect.

When I first tested emailprivacytester.com, I also checked Mail.app on OSX ~10.7, and iOS ~5, and I was quite happy with the results.

Now, I always check settings immediately after launching any app for the first time (and on OSX always run Hands Off!, which I greatly prefer over Little Snitch), so it's possible that I fixed obviously-bad defaults before getting bitten by them.

Unfortunately, I'm not sure what the author is trying to say -- is Mail.app worse in Mavericks, or has he just not bothered to configure it sensibly for his (our) uncommon usage preferences?
So if I understand this right...it means that no matter how far along the number line I go (and I can go a long ways out) I will always be able to eventually find a pair of primes that are separated by no more than 600?

The crazy thing to me is that primes get less and less dense as you get further and further out. It would seem to me that once you reach a certain threshold you won't be able to find two primes "close" to each other anymore because primes will be so far apart from each other. But this says I will always be able to find a pair pretty close together? (I may be looking a long time though)
People often reuse user/password combinations. So if attackers can find working combinations here, those are combinations that they can try elsewhere as well.

I think the coolest and maybe most misunderstood part of Markdown is that it is designed to make README files into reasonable HTML. In the process of designing something that made for human readable text files that can be easily translated into HTML it became one of the biggest text input standards on the internet.

Like JSON, on its own, Markdown is a nice little tool, but what people have picked up and done with Markdown is really inspiring.

This is absolute rubbish. Let's have a look at the Waterloo CS 458 assignments: <http://www.math.uwaterloo.ca/~dstinson/CS_458/F13/F13-slides.... Every one of those assignments that has you do practical work has you do it against a Waterloo-hosted virtual machine (as obviously anything else would be potentially illegal).
For the curious, the article is lamenting the fact that OS X's built in email client loads external images by default. This is bad behavior in an email client. Both spammers and legitimate email marketers use external images to track if you have opened an email. When you open it, marketers are tracking what you're doing (you received and opened it). But when you accidentally open a spam, the spammer is confirming that your email address is real and is receiving the spam and then selling your email address on spamming lists.

Nearly all modern email clients and most modern webmail clients have external images blocked by default for these reasons. They have a button or link at the top of an email without images loaded that says "Display images". You can also often select to always display from a particular sender. Mozilla Thunderbird, Gmail, Outlook, Android's built-in email client, etc all display this proper image handling behavior.

Oddly, Rackspace's webmail client for their hosted email service suffers from this same privacy vulnerability by default despite the fact that their competitors' webmail clients work properly. I posted a request for them to fix it: http://feedback.rackspace.com/forums/71021-product-feedback/...
Man, this scared the crap out of me as I've been using OS X Mail for years. As others have pointed out, the post is completely wrong, here's my privacy test result after I viewed the delivered message:

Yes - of course Load Images is disabled in settings. What else would you expect? If I press Load Image button most of those boxes of course turn red.
John Baez has had an interesting series of posts about this on G+, but IIRC the gist of it is that even though both Grigori Perelman and Yitang Zhang were somewhat outside the mainstream of academia, their work was not. Both of them built on well-known theories and methods to prove their groundbreaking theorems. Perelman's primary tool, for example, was Ricci flows, which had been used at least 25 years before his work. (I know even less about Zhang's work)

My guess would be that law enforcement doesn't do much at all for public safety and the level of violence in any given area is probably driven by economic or other factors.
Hilarious.

Would you rather leave this to capitalist corporations or the free market? I mean, maybe we should just have lots of Blackwaters running around performing "protection" services for the highest bidder.
Heh. True. But, there's a big difference between surfing a website anonymously and having your mail client on your modern OS sending tracking information confirming your email address and that you opened the mail out to every marketer and spammer that sends you email by default.
I haven't tested it, but it should.

They don't even do a good job of hiding it :/ the URL of the image stays the same and it is still accessible through the URL. All they do is remove its link from their interfaces...
I don't get it. The article talks not just about Zhang, but also about James Maynard, who is a postdoc and looks young, and is part of what you might call standard academia. His result is independent of Zhang's and is orders of magnitude stronger and is much easier to understand. Comes off pretty good for academia, really.

Also, remember that most people on Earth aren't in academia, but most people still think. So the null hypothesis is that most innovations won't come from academia. But a huge amount of them do anyway, including even your counterexample, who--despite his economic struggles--was still a lecturer at a university. You could make a similar argument for young people.

Our university system and our cultural obsession with youth deserve plenty of criticism, but the accusation that they're not making important discoveries isn't one of them, and it's totally unwarranted from this article.
You will always be able to find a pair of primes that are "close" to each other. However, the theorem makes no claim how far such pairs are from each other ;). To your point, primes get progressively less dense, which must also mean that these pairs get sparser still. It's probably quite vast distances between them, but infinity is a long ways, so it's not entirely surprisingly you find such improbably events with regularity.
"on average" is the wrong concept here. Just leave it out of your sentence and it's correct.

I'm conflicted...i love OS X, but Apple's other software efforts seem profoundly directionless. I'll leave Siri and Maps out of this since heir problems are more likely due to the data gap against Google (or is it whatever software processes they're using to wrangle data?)... But a standout flop to me is the App Store on iOS...I just don't get it...when I jump from a URL to a store link, I'm taken to a modal in which if I accidentally tap outside, the modal is gone and I have no way to get back to that app page except by revisiting the browser again...modals are, I thought, typically used for quick web transitions, not actual landing pages. But then the App Store itself is so slow that speedy transitions are irrelevant...why is it that every action, from scrolling to searching to clicking is so stuttering slow in an application that is core to Apple's mobile dominance?

I've never developed for iOS but the many complaints about CoreData and my own consumer experience with iCloud syncing doesn't give me much reason to think iCloud will kill Dropbox by merit alone
that sounds fine until you want to share data between applications as well as people.
Established scientists stop producing groundbreaking results because of tenure. Once you have tenure, the biggest incentive to work hard goes away; it's simple economics. (Hence "mathematics is a young man's game".)
"Probably no unrelated people at all were executed or imprisoned in 1917 or 1905" -- are you serious? Really?

There were bloody purges after 1905 enforcing 'summary punishment' against, say, everyone living in a specific village, in order to make a warning for others. My local area lists 500 official executions of revolutionaries, but 2000+ 'collateral deaths' happened in the process.

1917 was followed by (1) a civil war, (2) class warfare - reprisals against millions of people where the fact if you were killed or deported was determined in part by wealth, but in part by your connections and local denouncements. (3) internal conflicts such as Tambov rebellion which also meant that you can easily lose everything for something your neighbor did.

Most societies that lived through a social calamity did not endure long periods of internal treachery affecting not a small prosecuted minority but huge parts of population - well, Pol Pot and China Cultural Revolution did, but I'd argue that they had similar effects on their societies.
> It would seem to me that once you reach a certain threshold you won't be able to find two primes "close" to each other anymore because primes will be so far apart from each other. ]

That is not quite correct. The average gap between primes gets larger as you move further along the number line. But, you will still get the occasional consecutive odd numbers that are close to one another. In fact, there is an old conjecture (Twin Prime Conjecture[1]) that claims that there are an infinite number of pairs of consecutive primes separated by 2.

PS. I'm not a mathematician (engineer with some decent math background), so I might very well be wrong.

>>How can anyone have faith in such a system with such gross inequalities?

The system is working as designed and as intended.

I think people need to rid themselves of this romantic notion that the government serves "the people" and cops in particular are supposed to protect the innocent. Both of them are ridiculously childish beliefs. The reality is much harsher. Adam Smith laid it out more than two centuries ago in his book Wealth of Nations:

"Civil government, so far as it is instituted for the security of property, is in reality instituted for the defense of the rich against the poor, or of those who have some property against those who have none at all."

Ask HN: DevOps guru on demand?
I'm looking for help with initial network setup - simple tasks that a devops guru could probably do in a day or two. Are there any services that make this readily available? I don't necessarily want to learn vagrant/docker/chef/puppet as a) it's not my core competency and b) I'm not looking to build an on demand scalable infrastructure that can handle 100000 users.

For example, I need help with an initial setup of an AWS VPC, IPSec VPN to local network, setting up route 53 with DNS for a site hosted within the VPC (small company like 10 users, but may want access from phones/tablets), a micro openVPN instance for remote access, 1 sql box, 1-3 linux boxes. Weekly snapshots of all drives.

Because of the nature of our work, we can't do something like heroku or elastic beanstalk. Code deployment, updates, etc. I can handle, but learning all the AWS ins and outs is probably better left to the experts. But where are they?

Oh yeah, and I'd like the entire thing replicated in real time to another AZ for disaster recovery.
Wow, this is really useful information, thank you!

Since I wrote my original comment, I went out and started doing more research into this. At this point, I have my main home server[0] now accessible via IPv6 using freenet6. However, I did apply for SixXS, so I can hopefully put my entire house on it (my router's an Asus WL-520GU, which currently has DD-WRT on it, but is compatible with OpenWRT). Though I'll be looking more into the Hurricane Electric service.

I'm really liking this, since now I can access my devices directly, without having to try to negotiate firewalls and weird subnets!

Thanks very much for the advice!

I think the mathematical edifice is sound, but I can certainly see how being as divorced as possible from typical faculty responsibilities makes it easier to do original / groundbreaking research. Too many professors I know spend the bulk of their time attending to e-mail, grant writing, and traveling to give talks about work others have done. What little remaining time they have is often devoted to teaching. Some of them openly complain about how little time they have to actually think about things, while others seems to roll with it (being famous in your field is not a bad gig). Worse, the more successful you become the more these tertiary responsibilities encroach on your time. It's an open secret that the best-known professors in certain fields basically sign their names on the papers their postdocs and grad students write and that is more or less the extent of their research contribution. Cutting all this out, even if it means moving in with your mom in Moscow, could indeed be a viable option...
You are in a maze of twisty little rooms, all alike.

"Instance" has a very well defined meaning, which leads to some standard implications.

It means one particulate <thing> out of several, which are all alike. It implies that your <thing>, and in fact all <thing>s, has (have) no physical reality. It implies that <thing>s can be created and destroyed at will.

It is also completely generic. You can have EC2 instances, ${APPLICATION} instances, object instances (in absolutely any object-oriented language, and several that aren't), database instances, etc.

A virtual private server is a cheap knock-off of a real physical server. A server instance is something you get from an API instead of having to hire a guy to plug things in.

Implementing a passable undo with a database-backed system gets a lot easier if you have an append-only record of every transaction.

Rails has a great gem that adds this feature with a minimum of fuss (https://github.com/airblade/paper_trail). There's even a Railscast that goes over how to use it to implement "undo" (http://railscasts.com/episodes/255-undo-with-paper-trail).

There's also ambiguity. I didn't think math was funny just because of the pun, but also because of the way people use math to justify homeopathy. It's mathematical, so it must be true. From a similar cultural perspective, I can see something totally different but also valid.

Wow, this is a great story. First of all, props to the writer for weaving a bunch of different threads together in a way that made sense and was understandable to non-mathematicians without dumbing it down too much. And this is why I love math. There are so many great characters and themes in this story.

I love problems that can be stated so simply and yet are so fiendishly difficult to prove.

I love the idea that there is room for everybody in mathematics, from the lone genius outside of academia, to the young post-doc, to the unlikely collaborators.

Most of all, I love the idea that it's okay to fail, to throw out dumb ideas along with brilliant ones and that everyone makes mistakes, even Ph.D.'s in mathematics. We need more of that in education and academia generally.
In the context of servers, I have never seen other web hosting platforms use the term "instance," in the context of on-demand server instance vs. just give me a server. While it seems commonplace now, I don't recall reading about other hosting platforms referring to their services as instances. Can you point to literature that does? For instance, from http://aws.amazon.com/ec2/instance-types/ : "You can think of instances as virtual servers that can run applications." That's the AWS context of instances.
