nsa.gov and www.nsa.gov are two different hosts as far as DNS is concerned. They can and often do point to different places. This is a good example. www.nsa.gov is an alias to Akamai (a large CDN), and nsa.gov points directly to an NSA owned machine (because for technical reasons you can't have an alias or CNAME at the zone apex), people usually configure these machines to redirect to the www hostname.

Browsers should never "fill in" www, because as I pointed out, www might be a completely different host or service.

Even if you can't power every transistor simultaneously, shrinking allows you to layer on a whole bunch of specialized logic blocks. They're dark almost all the time, and when they're lit up they're displacing much more energy intensive general purpose computation.

Things like hashing/encryption functions, hardware encoders and decoders, even full blown FPGAs are all candidates.

You can also make more, slower cores, running at lower voltage, if you've got any embarrassingly parallel problems to work on.

It's not as attractive as just getting faster and more energy efficient across the board like we have been doing, but there's still room to move there.
Better solution: require VPN connectivity and don't expose SSH on any port to the public Internet.

Running services on non-standard ports will make the next admin that takes over this server want to track you down and smother you in your sleep.
To be clear, this doesn't mean teens aren't using Facebook. It just means they don't call Facebook their "most important" social network. That's a huge difference: more teens are likely still using Facebook than Twitter, they just don't consider it their most important social network.

This means Facebook has essentially reached utility status, which is reflected anecdotally in my life. It's replaced email for a generation. But that's arguably a fine place for them to be: if you own the entire backbone of people's communications, there's a lot of money to be made in that. You'll find a lot more teens who use Facebook but not Twitter than the inverse.

To put it another way, if asked I'd say Hacker News is "more important" to me than Google Search. But Google definitely makes a lot more (potential) money off me.

I run my ssh server on port 443 in addition to 22, because some network connections block anything except 80 and 443, and this allows me to easily proxy through that broken network connection.

(Actually, I appear to have stopped doing this. But it's something to consider if you are on weird networks on a regular basis.)

Come on- isn't the prospect of being in a personal transportation that could override your controls not scary at all?

And remember, it isn't just potentially the government who might do this. What about hackers working on behalf of some malicious and sinister agency? What if instead of kidnapping you, they mess with the controls and cause you to drive into incoming traffic? Or worse, an entire highway's worth of cars in a terrorist attack?

I'd be first in line to buy an autonomous automobile, but these are still real concerns. The more control you cede to programming, the more rigorous the code has to be.
The brilliant part is Amazon doesn't make money directly by selling books, they make money by not paying for books until they are all sold (so publishers are effectively floating them interest free loans for every new title).

Question: Why do some physicists believe it's a problem that physics isn't unified? It seems odd to assume that just because throughout history we've unified more and more concepts that all of physics can be unified. What if there's a limit? It's interesting to think that 100,000 years from now, physicists will still be working on the problem since no one would know it's impossible.
Even if that's the only thing, that's not useless. Just don't mistake it for a security measure.

Also, you can put port numbers in your SSH config, so you never have to type them.

Ask HN: Strategies for getting customer development/feedback on Freelance Tool
I'm building http://signup.codefix.io but am struggling with getting feedback on if this actually solves a problem for freelancers and what problems I could solve for them. The idea came out of my own experiences doing one off fixes for people.

Anyone have suggestions on how to get feedback from freelance developers and people who would post projects on the site?

Thanks
The thing with Bloomington is that it's very bike friendly compared to most cities of similar size and there is a substantial cyclist population considering half of the town consists of students that have nowhere to park their cars.

Your average noncollege town isn't like Bloomington.
Not sure why anyone should let "cultural stigma" have any influence on what they do. Who cares?

As for sidewalks being safer than streets, that is a myth. The reality is streets are much safer for bicycles. This is a well covered subject, Googling "safer bicycle street sidewalk" brings up a lot of info. The main reason is drivers are not expecting anything on a sidewalk to be moving at bicycle speeds, so cars turn in front of bikers much more often.
Something as simple as an exploit against a php script could lead to unprivileged code execution & something as minimal as memory exhaustion could kill off your sshd process. If the sshd process is killed, and the attacker knows what port it was on (netstat -na | grep LISTEN), the attacker could spawn their own daemon on the unprivileged port that was previously being used for sshd, and that daemon could be used to collect plain-text passwords that people try to use when logging in. Heck, they could craft their daemon to log all keystrokes & which could grab the local root password.
Is it possible for the NSA to do timing analysis if they control all internet backbones? They've installed that special room at AT&T to gather traffic. If they do that at enough ISPs would it be possible to reveal all Tor hidden services operating from within the US?
This is yet another example of how we are /very/ rapidly plunging (like it or not) into a future where our amazing advances in technology make most of what we consider "work" obsolete and unnecessary. In a sense, we (as a species) kind of won that "life" game.

Right now a large percentage of society is doing "work" that isn't particularly complicated or difficult. I's necessary, of course, but it's the kind of thing that we are - with increasing frequency - starting to think we really should take the very small shell script[1] option.

Many obvious references could be made to Marx at this point, of course. If you want to. I prefer, on the other hand, the idea that our economy is simply taking on some Star Trek-style, post-scarcity traits.

Technology can never replace /all/ jobs, of course. More precisely, Gödel showed us there's always more complicated, more interesting tasks out there. The tasked involved in maintaining the baseline needs a person has in life (food; shelter, basic health-care) and even a few of the "luxuries" (transportation, communication, the general-purpose computer), though, are going to simply be solved problems.

Autonomous cards are indeed going to be a very scary prospect, and it isn't (primarily) because of any safety concern. The changes to society this technology will cause (such as those 3M truck drivers) is pure, distilled terror for anybody that wants to hold on to current social model.

Worse yet - the self-driving car is just the first of many technologies that are happening right now. Millions of unemployed drivers is nothing compared to /billions/ of bureaucrats, low-level factory workers, fast-food/walmart-type workers, and middlemen of all sorts and the like being made obsolete.

Hmm... what was it that Marx said about revolution?

We better stat getting ready for these changes in the meantime.

> Frankly I'd much rather do that then have my server on a non-standard port.

Frankly, the problems with key security and management are much worse than are being discussed. Using only keys is fine as long as your keys are secure and you know which is which and control all access and immediately remove any key which needs to be. In a complex environment, this is extremely difficult and more prone to security breaches than password access.
The assumption is that bots don't usually scan other ports: way too inefficient for them to scan all ports for every potential target host.
It would be better to say that this is a visualization of how a certain kind of dictionary compression works.

The outer limits of data compression lie in using predictive models plus arithmetic coders. A visualization of how they work might look very different.
They're where they always were: hindsight. There are tons of brilliant people, but it takes a good chunk of temporal separation to be able to spot them through history and see their world-changing contributions.

Ask HN: What to use for a mobile based HTML app?
What framework would you recommend to build a quick prototype for a mobile app using HTML5? In the past I have used jquery mobile. Now I was contemplating on using Angular or ember.js in combination with bootstrap. What are your experiences?

The most important requirement is that it is quick to write something, that works across mobile devices and looks presentable.

It's not odd. To me it is only logical to assume that if we can explain most physical phenomena, the trend may very well be extended to the rest of them. Besides, one can find a surprising amount of symmetry, simplicity and beauty in the Universe.

Note: I left the "some physicists" part of your question out of the answer because some physicists would believe in anything.
Because physicists believe in parsimony?

Less flippantly, simply that if the two (on their own, staggeringly accurate) main theories we have about how the universe works are as fundamentally incompatible as the ones we've got, then there's probably something we don't yet understand about the thing they're describing.

The search for a ToE isn't so much about "unifying" QM and Relativity as it is about figuring out what it is that we don't yet understand about the universe that allows them both to be as true as they appear.
The more people TOR use, the more secure it becomes. All attacks base on analyzing incoming and outgoing traffic or monitoring nodes which use outdated tor version. And why should be using "open wifi networks" more secure or anonymous? You don't know whos running them and who you can trust. With TOR you could still go over open wifi while having not (or much less) to worry about who may be sniffing on that wifi access point.

The California law strikes me as unreasonable. It's an example of the law being expedient rather than just: The person who should be responsible is the person who perpetrated the "negligent or wrongful act or omission in the operation of the motor vehicle." But if that person has had to borrow a car then perhaps they don't have any money, so plaintiffs want to take it out of the pocket of someone who we know has at least enough money to buy a car notwithstanding their apparent lack of any wrongdoing. The just outcome when the owner lends a vehicle to someone who is not known to be irresponsible is for the driver to be liable and, if the driver may not have enough money to pay the damages and we want the injured party to be made whole, the government should establish a requirement to carry sufficient insurance.

> In general, the owners of things are liable for damages caused by those things.

In general the owners have to have been at least negligent to be liable. And the cases to the contrary are similarly contemptible instances of injustice where the lawmakers see sympathetic plaintiffs and nearby deep pockets from which to filch coins and for political reasons (in the case of legislatures) or because they are restricted to deciding a single case (in the case of judges) are more inclined to impose liability in innocent bystanders than set out a requirement for parties to insure against losses incurred through the acts of culpable but insolvent third parties.

> The question of liability is not irrelevant, because insurance does not transfer liability it transfers a quantified, limited amount of risk. If I cause damage in excess of my insurance coverage, I am still liable for the damage and I'll have to make up the difference.

But that isn't the common outcome. The common outcome for a self driving car is for there not to be a collision. In the rare case of a collision, the common outcome is for there to be insurance which covers the damages. In the rare case the insurance is insufficient, the common outcome is for the vehicle owner to be insolvent (because owners with wealth to protect will tend to carry larger amounts of insurance).

If you want to be pedantic, the question of who has liability is complicated. But in the very large majority of cases the relevant question of who pays for the damages is simple: Cars are required by law to be insured and the insurance company pays. And if that isn't the common case then it's a strong argument for increasing the legally mandated minimum amount of insurance.

Ask HN: Any Chemistry hackers here?
There's a project I want to undertake. I want to do it out in the open. I've been inspired by a few Maker projects as of late. I keep hearing "you should file a patent right now" when I have shared this idea with close friends. Which is why I want to do the opposite.

I don't know enough about the specific domain for the crux move of the solution. I think the solution lies in Chemistry or Chemical Engineering, but I am not certain that the problem is solvable in a cost effective way. My gut tells me that it is.

The first step is for me to be able to ask some very specific questions about phase change temperatures and latent heat of fusion of different chemical compounds. Any takers? The background info is too much for an Ask HN post, but I ABSOLUTELY promise that as soon as this enters the realm of "yeah, that's probably solvable" I will start posting the whole project and living it the Maker way.
And it's not solved. Still plenty of skin cancer downunder. It kills.

I get your point but perhaps theres a sys admin monitoring a DNS server somewhere and realizes theres a bunch of unusual traffic then on his break he checks HN and realizes the NSA site is down, he then does a little investigation and wolla he connects the dots and has something he can teach the rest of us. It's collective intelligence if you will :-)
I agree with everything you said except the last part... "Another possible exception is Stanford MBAs, specifically."

I will also add, it is important to have a good combination of good team with a good idea. You can't just have a great kickass team and expect your idea to be successful. Think Color, Foursquare, Cuil etc.
If Perelman had just taken his prize and money like most others would have, I most certainly would not know who he is today. Avoiding fame is clearly not where his genius lies.
>famous or notable mathematician.

Mathematicians are famous among people branded as "nerds" and "geeks." I know who many of them are, but I'm a huge nerd.

If I had to name one living mathematician that's famous by the standards of popular culture, the obvious choice would be John Nash. They made a Hollywood movie about him, thus he became a household name.

Pretty soon, when the Alan Turing movie starring Benedict Cumberbatch hits theaters, he'll become a household name as well. I know that he's passed, but I ran out of famous mathematicians after the first one.

I would love it if people who actually contributed towards the betterment of mankind became a bigger deal than pop stars, actors, and athletes, but most people simply aren't smart enough to recognize what really matters in life.

Access to presidential records is actually quite restricted including a 12 year delay in most cases[1]. I think the article is incorrect that a FOIA request could force the president to produce an email.

And unlike tech execs and anyone else the president is not subject to search warrants or subpoenas in many cases due to "executive privilege"[2].

The PRISM program, which captures a huge fraction of world email traffic, is "the most prolific contributor to the President’s Daily Brief" according to the NSA[3]. Reading other people's email on a regular basis probably makes you cautious about your own email habits rather than being worried about FOIA requests you can probably ignore.

Despite all of these protections our presidents still feel they have to take the extraordinary step of not using email at all. Very shady.

You either believe in natural or supernatural explanations for the universe. If you accept the latter then the discussion is moot. If you're a scientist your approach is the first.

It is difficult, perhaps impossible, to come up with a philosophically sound logically consistant explanation for natural phenomenon which isn't unified and connected at a fundamental level. Two incompatible sets of natural explanations are vastly less likely than one unless we're falling back on superstition again.

Hence on some level there will be a unified way of approaching and talking about physical phenomena. Now, is that underlying consistent theory achievable? Well that's a different question. If the unified explanation for all natural things, at its heart, relies on physics we just don't have access to - either it's too small scale for us to ever probe, or too large scale, or no longer manifested at this point in the universe's life (there are examples of this I could describe but that'd make this post too long) - then of course we would not ever get to a satisfactory scientific account which is unified.

But efforts to get there tend to reveal other interesting things so are worthwhile even if we never achieve the final goal.

Plus because it's so specialized and inaccessible to the layman, the degree to which there's already tremendous consistency and unification in our theories of the underlying nature of things is dramatically underappreciated by most people.
This is one of those cases where the poetic language used to try to explain complex phenomena to lay persons is unhelpful. It doesn't really mean illusion in any sense consistent with what people might imagine that to mean.

Indeed it's not really that revelatory. "Experiment agrees with what we already pretty much know" would have been less interesting.

If you want to save the full format of the file, including layers and whatever other GIMP magic you've created, you'd best save it in GIMP-native format.

If you're just doing some quick tweaks, you'll get used to the export option and ignore the prompt to save on quit.

Since most of what I do are quick edits of screenshots, the latter works fine for me. If I were a graphic artist, I'd probably get more than slightly peeved if my afternoon's work were lost due to an incompatible file format save w/o prompt.

Not prompting the user leads to massive loss of user work and state. Prompting the user is a minimal overhead to avoid this risk.

NSA Blames ‘Internal Error,’ Not Hackers, For Website Crash
Well, more to the point, it doesn't imply anything about the business end of the agency's systems being compromised. If you hacked into the actual CIA or NSA as in having similar access to an authenticated agent, that would be quite bad for them. Taking down their website is something they don't really care about.
