Edward Snowden interview – the edited transcript
Speaking only for myself, I visit Quora so frequently that I pretty much always have a login cookie stored, so I never see the login page.

That said, given my very public and vocal arguments against "walled gardens" in the past, why do I tolerate Quora? For the same reasons I tolerate G+, Facebook, etc. I annoys me and tickles a sore spot regarding the way I want things to be, but the value of the content is sufficient for me to "grin and bear it". But if there were a really good Quora alternative that was more open, I'd work to promote and support it. I don't know of one offhand though, especially considering network effects (that is, the value of Quora isn't the Quora software, it's the people posting and answering).
> 50 mile range sounds great, but that's under "ideal" conditions, which happens roughly never. I'm curious what the range would be in the real world.

In that graphic, change the elevation to 6ft and you get much more realistic ranges. The default elevation is 500ft (top of a small hill).

I'm a HAM operator, that device's frequency is just a bit above our very popular 2m band. The ranges they indicate at more realistic elevations sound about right for me, for a data connection at 2W.
I tried to learn Mandarin a year ago because I started a relationship with a Chinese girl. The words made no sense (felt just a completely random sounds), got angry and gave up after a couple of days.

A year later, after hearing a lot of Mandarin (she speaks quite a lot of Mandarin over the phone and I spent a month in China), I gave another shot. It feels much easier, more familiar and less random.

Of course, it's a totally anecdotal 'evidence'... But getting familiar with the sound of the language before actually studying might help.
Teach them something.

There was an article about it making the rounds a few days/weeks ago. A guy basically takes on a class of 30+ people for two days when hiring, teaches them something, then hires the one who did best. The rest are still happy to have learned something.

Another good approach might be flat out asking "Tell me about the last time you learned something new"
Zigbee is very low power and much higher frequency. You have to be within a couple dozen meters.

The goTenna thing is much higher power and lower frequency. It reaches at much greater distance, and can even go a bit around small obstacles (it's 2m band, so don't expect miracles, but still, it's not 100% line of sight).

NearMap is an Australian startup that has a similar product but with higher resolution and more frequent refreshes. But only operates in Australia now, as far as I know. http://nearmap.com

From Wikipedia:
A unique exclusive process of imagery capturing, processing and publishing is used. Traditionally, high resolution aerial imagery has to be captured by a low altitude flying aircraft, then the data is manually processed and stitched together digitally to create a PhotoMap, a slow process which can take months to complete. nearmap speeds up this process by using their own engineered camera capture equipment, named a 'HyperPod', which is attached to Cessna 210 light aircraft, which fly at a high altitude, enabling entire cities to be captured in a day or two. Once the imagery is captured, it is processed through super computers which run software known as 'HyperVision' which automatically processes and stitches together the many individual photographs captured into one virtually seamless PhotoMap. These PhotoMaps are then hosted on nearmap's end user web portal, known as 'MapBrowser'. Along with traditional top-down photography, the HyperPod is also able to capture oblique aerial photographs from 4 different angles and digital elevation model data at the same time.

How is bandwidth handled / incentivized? Is this intended for long term storage (few retrievals), or for files that are accessed frequently?
I ordered mine when the page went live. I hope to get them soon and start enjoying them. I'm actually headed out to Colorado to climb the Collegiate Peaks so I'm hoping they get here before mid-August.

Don't worry. I've got a ham license and I'm bringing my 2m/70cm HT with me and a SatCom set too. Would be nice to give it a go in real-world conditions.
This is so true. In 2010, I worked on Mainframe. Yes , 2010 and yes on Mainframe. It was project interfacing modern data services with mainframe. I had to learn COBOL and z/OS architecture on how to do it.
I graduated in 2007. When I talk with people of my age , they are so surprised that mainframes are still around and I worked on Mainframe.
Many people don't know that large percentage of financial , insurance transaction still happen on mainframe.
Remember you purchased policy last time or made changes or swiped your credit card ? Guess what , Mainframe was monster involved in processing. Now that was also programming.

So yes , regarding argument at hand , I think programming may not "necessarily" involve math ( as taught in school , college --FFT, DFT, DE, Matrix etc. ) always , math is integral ( sometime hidden ) component of programming.

What if this "less-evolved" system is actually a step forward in our evolution as species? Because we use a lot of electricity for the machines required to create, maintain (and promote) our food, what if we could just skip that and directly plug the energy into ourselves?
Ask HN: What are the best (book) libraries in the world?
Every time I read about an excellent library in a particular U.S. or European city, I get a little jealous. It seems wonderful.<p>Does anyone know of a good clearinghouse or place to find information about libraries? Which ones are very friendly and pleasant for a foreigner visiting to come in and read there? Which ones have good digital collections? How hard they are to join?<p>Or even if they're restricted, it'd still be interesting to hear about.<p>It seems like it's all fragmented local knowledge. Share a bit about your favorite libraries?
during the first 3 years we were basically forced to hire from two pools of candidates:

1. people we have worked with before who are known quantities i.e. smart AND good

2. people with minimal experience who we deemed to be smart after talking to them for a few hours

it's worked out well. to be deadly honest nobody else wanted to work for us.

Where does privacy fit into the philosophy and tech?
Same way it does everything else in America: free speech.

Furthermore, if your web server (or database server, or any other interet-facing service) is vulnerable, it won't matter which programming language you are using. Assume that all input is hostile.
Not at these frequencies. It's prohibited by the FCC. See some explanations from an insider above.
What about the right to free association? Suppose you had a girl/boyfriend that was using drugs, unbeknownst to you, and that this was a deal-breaker for you. Who would argue that you have no legal right to break up with them once you found out?

You have a moral right to choose the people you hang around, because the consequences to your own life can be disastrous. Can you imagine landing in jail (and the incredible strain of testifying in a trial) because you were used by your friends as a getaway driver, without your knowledge? This kind of thing actually happens in real life: http://www.mainlinemedianews.com/articles/2014/07/18/main_li...

Given that each of us has the right to associate freely on a personal basis, why should that right be so blithely ignored when the relationship in question involves money?

Granted, pot is not nearly as dangerous as other drugs can be (including alcohol.) However, the whole question of the danger involved is best decided by the individual, not the group. After all, it is your life that's on the line when dealing with others, not the group's.
Well, somewhat notoriously, there has been a rolling debate for better than a century now over whether "higher" sciences simply are complex subdiciplines of "lower" sciences. E.g., are all biologists ultimately just physicists? How about psychologists? Economists? The proper meaning of "are" itself in that sentence also, rightly, is the subject of significant dispute. But the analogy isn't the best since I think that philosophers enjoy that question a lot more than actual scientists.

A more interesting example may be law and economics. There has been a concerted movement by certain economists/legal theorists to show either that law is simply applied (or misapplied) economics, or that it should be. (Here's a taste: http://www.law.berkeley.edu/faculty/cooterr/PDFpapers/stratc...) Again, though, the analogy is imperfect. I don't think that many would claim that law "is" economics, but rather that legal rules are or should be explicable in strictly economic terms. Though maybe this would satisfy some definitions of "is."
Any lamp hosting would be good. AWS/Azure/heroku are an overkill for such a need. As many pointed out, wordpress can take care of all your needs. Even though I would recommend a lamp hosting instead of a managed wordpress hosting.

Probably everyone knows the math; I just think they're exaggerating the relevance of this model to real life.

I'm with the commenter (here) who said that real life is more likely to be an initial-value-dependent or path-dependent PDE. Someone else said having a high-IV person on your team will raise the slopes of everyone else which seems also right: the issues are multidimensional, not affine 1-D.

Ousterhout is taking sides (smarter > more experienced) which is fine; he can make that argument. But using y=mx+b as x→∞ doesn't count as an argument; it's rhetorical flair, not rhetorical substance. The substance of his reasoning seems to be "That's my opinion based on my experience in my past jobs".

"Look at what I've done" is neither the y-intercept nor the slope in this increasingly stretched metaphor. It's a definite integral (area under the curve).
After all the Snowden stuff, I worry that it makes it too easy to 'erase' troublesome books when no one actually owns them.

You're right. I could use a good radio. Downsides: the Bluetooth local connection is wasteful, the bandwidth is going to be pretty low, and I can't immediately see if they have an open developer license.

Wireless is very hard. If you've spent much time working with it, it's amazing how good wifi and cellphones are.

You can only express some kinds of purity if you can enforce it at the type level. An otherwise pure data structure that contains mutable elements is a violation of purity; a contradiction. If you cannot express a data structure which guarantees that its elements (and its elements' fields/elements) are pure, you cannot express a pure data structure (also known as a value).
I'm okay with that condemnation. Do you have a real refutation?
OMG, this is amazing. I've already added it. Really appreciate it, this will definitely come in all sorts of handy.
I agree that the tone is a bit sensationalist. It is New Scientist, after all. But note that the article itself makes your point:

> That should not come as a complete surprise, says Kenneth Nealson at the University of Southern California, Los Angeles. We know that life, when you boil it right down, is a flow of electrons: "You eat sugars that have excess electrons, and you breathe in oxygen that willingly takes them." Our cells break down the sugars, and the electrons flow through them in a complex set of chemical reactions until they are passed on to electron-hungry oxygen.

> In the process, cells make ATP, a molecule that acts as an energy storage unit for almost all living things. Moving electrons around is a key part of making ATP. "Life's very clever," says Nealson. "It figures out how to suck electrons out of everything we eat and keep them under control." In most living things, the body packages the electrons up into molecules that can safely carry them through the cells until they are dumped on to oxygen.

> "That's the way we make all our energy and it's the same for every organism on this planet," says Nealson. "Electrons must flow in order for energy to be gained. This is why when someone suffocates another person they are dead within minutes. You have stopped the supply of oxygen, so the electrons can no longer flow."

That sounds worse than "price parity", it's like mandating an infinite price for every distribution channel other than Amazon.

This was discussed in #bitcoin-wizards recently:

http://download.wpsoftware.net/bitcoin/wizards/2014-07-17.ht...
The Wikipedia article on the topic gives a good overview:

https://en.wikipedia.org/wiki/Consequences_of_the_Black_Deat...

As I recall, James Burke's Connections discusses this tangentially at least once (several times as I recall -- it somewhat traipses back and forth across history a bit).
We are working on several ways to prove to ourselves and the community that what we have is correct. The most important is obviously testing. We have tests that demonstrate the problems we found, and Ark passes those tests. Publishing this explanation and soliciting feedback is another.

We have run Jepsen and have not been able to get it to show data loss in TokuMX. The problems it found in MongoDB were already fixed in other ways in earlier versions of TokuMX, but we're trying to get Jepsen to demonstrate the other problems we've found.

Model checking may be another way we can prove correctness, but since Ark is so similar to Raft, I think the Raft model in TLA+[1] is probably sufficient. Anyway, we'd also need a proof that the model is equivalent to the implementation, and I don't know of a way to do that, so I think functional tests are more important.

In any case, we'll look in to using a model checker, and any help would be greatly appreciated. If you're interested, feel free to email me.

Mathematics is the study of quantity and structure. Reasoning about how to mutate some state, defined as a set of values, according to some domain-specific logic, constrained by the execution environment and invariants, is most assuredly mathematics.

It's a bit of a false dilemma to choose between experience or aptitude.

In the start-up period, though, aptitude is a better strategic choice in that you need people who can grow as quickly as the venture.

Later, you need the people with experience, even if they're a bit slow. They're the ones that have been bitten by the edge cases, the deadlocks, the XSS openings - and know to avoid them.
Neat. Reminds me of Slime Mold.

I read it more as an illustrative example to open up the following discussion than a terribly serious model of real life.

He does riff back on it, but it's five minutes of perspective tossed at teenagers, not anything formal.
This article is sexist because it just adds to stereotypes that women are weak, over sensitive, over emotional and always whining about something no matter how small in significance. Whining about getting a compliment... go trade places with a construction worker (who are building your comfortable offices and make your cushy life possible) and then tell us about death by a 1000 cuts.

This woe me Im a woman sh*t has to stop.
Ask HN: What are your favorite tech-related movies?
What are some of the best movies that feature interesting technology, or portray development and hacking realistically?

I'll start: maybe not particularly realistic, but The Matrix (1999) has always been one of my favorite tech-heavy movies.
It's also worth mentioning a similar advantage the toddler has: it's going to have more than a decade before it's expected to have adult fluency. Mind you, depending on the age of the toddler you want to emulate, you might just be able to get away with simply learning the word for 'no'...

Ask HN: Get on freelance sites or start a corp for some extra income?
Is it better to get on websites such as E-Lance to generate a bit of extra income or start your own consulting Small Corp/LLC?

Without going into too much detail I ask because it seems like a good time to make some extra money in our industry especially if you have engineering/development skills. Not sure where to start but I am sure I want to use up my time wisely. The type of work I am talking about would be part time small to medium size engineering/development job's after full time work. Meaning minimal overhead but best return for the time spent.

(For Example)
Some pros I can think of going the corp. route would be:

1) building some intellectual property especially with clients that are not very interested in the source code but really interested in the final product.

2) This route you can take equity as a payment rather than just cash.

Some pros of going the E-Lance route are:

1) Low overhead to none at all can just get to work.

2) Hassle free generally.

I am interested in hearing from HN readers who are doing this already and what challenges/benefits they are facing or have faced with each route.

Thank's in advance.

"This is why when someone suffocates another person they are dead within minutes. You have stopped the supply of oxygen, so the electrons can no longer flow"

Oh i see, that is what happens. That makes sense now. Didn't know New Scientist has CSI edition too.
Just eliminate the IRS and income taxes, and this problem goes away. Move most government services, for which there is an actual market, to private for-profit or non-profit organizations, or voluntarily assembled communes or co-ops. Fund the rest of the government apparatus through usage fees where the government service is providing value that someone will pay for.

Does this expose a "free rider" problem? Yes. Is that important? No.
I, for one, would find that scenario totally acceptable.
Very nice write-up!

It certantly easier to make a complicated case the broader the data channel is— so this is just one reason (along with scalability and cost-of-decentralization) that Bitcoin is pretty stingy with sidechannels.
Everywhere we look there's life. It's incredible. It's discoveries like these which make it hard to doubt the existence of life elsewhere in the universe.
FWIW, thats usually called 'delegation' or 'outsourcing'. Apparently it's intentionally not resistant to this (sounds like a pretty bad idea— IMO, but apparently intentional). See the IRC log I linked above.
Sigh, if only people this clever were trying to do good in this world.
(1) I don't understand how the programmer wasting 6 months relates to my example. (2) I don't believe you know what math is/isn't, calculating missile trajectories is just one way of doing math. Math is not the same thing as Arithmetic. Also, depending on the type of plugin, math can be quite a useful tool. For starters, if you're playing with Facebook's graph api, knowing about graph theory can be quite handy.
The Matrix is probably my favorite movie of all time. I've watched my DVD copy so many times that the DVD is wearing out (eg, has scratches, etc.) and I just had to buy a new DVD of it.

Otherwise, I like Hackers a lot (despite the unrealistic aspects), as well as Anti-trust. War Games is another of my favorites. Also, Tron and Tron:Legacy.

Swordfish is also entertaining in its own way.
I know it won't help, but I was thinking that one could keep hot backups by doing a fork() suspend() and then diffing the heap in realtime to migrate state between processes. Trying to keep state on the heap instead of the stack is a huge start. But this is stuff you already know.
That only works on direct person-to-person systems, not decentralized systems where the entire network has to reach consensus.
That's really cool. But kind of sad that it takes so much chance for these people to come across each other.
i'm sure that this will cause no amount of poor people to no longer have enough money for food, water, or shelter, much less health care, education, or other social contract goods, because enough non-profits will spring up to fill the gap and richer people will just be begging to fund them with all their freed up capital from no longer having to pay taxes. right? right? man this just sounds so pleasant a society to live in, i can't wait til we get there.
