You're forgetting that Everest isn't on the equator. Distance from the center of the earth doesn't matter; distance from the axis of rotation matters. So you need to multiply Everest's (height + radius) by the cosine of its latitude.
I have a mechanically adjustable desk from http://multitable.com/ - the hand crank is kind of pleasing. It's not as fancy as the electric motor desks, but then again it doesn't have an electric motor...

I'm actually using a tabletop that I bought from Ikea for the desk surface. I just bought the bare frame for the desk from multitable to keep costs down.

I think all in all I paid around $600. It's pretty nice.
GCHQ: the web is a terrrorist's command-and-control network
Well, again, I can't be sure, and you can't verify without reverse engineering the chip.

But that's not how PUFs work. The whole point of a "physical unclonable function" is that it's not just a set of bits that can be programmed to an arbitrary value; it's a part of a circuit which, based on physical characteristics of the apparatus, deterministically generates a response to a given challenge. The idea is that there is no such list for the PUF internal values--they're not controllable, and it would be extremely difficult to read their internal state without destroying the chip. Making lists would be very awkward: according to the Apple iOS Security Guide[1], the KDF takes 80ms per passcode attempt. So, generating a list of PUF outputs for all 10,000 4-digit numeric passcode would take Apple ~14 minutes--and it must be done on each device.

So, it's theoretically possible that Apple spends 14 minutes per device making a list of PUF outputs given all 4-digit numeric passcodes. However, a user who uses any other passcode would be completely unaffected (except having the search space reduced by 10,000), and I consider it highly unlikely that Apple can afford 14 minutes per device just for potential nefarious use given the volumes they produce.

Also, note that almost all other keys are 'tangled' with the output of the PUF, so a PRNG failure is not likely to cause predictable keys, depending on the failure mode and what PUF stimuli Apple records.

Of course, this is all a moot point, as none of this is verifiable (at least, to me and you).

This may make sense to a physical scientist, but biological phenomena do have a concept of time, because many biological molecules have an evolutionary history. It's not only that something was, but also that something is that embodies the trace of what was.
Hyperboot
Considering everyone beyond the retirement age is already effectively getting a basic income, or that anyone on unemployment is getting a temporary basic income, or that if you ignore the beuracratic overhead and injustice of welfare then food stamps + section 9 + the free electric programs sum to a near basic income, albeit a much worse implementation in every way, that is hugely destructive for economies and persons involved.

People already love getting those income tax returns - when you pay in more than you needed to, and you get the difference back. Basic income is the exact same thing - most people would be paying in significantly less than they get out, while those above a threshold (preferably the peak happiness threshold of income, that varies by location but in general on an individual basis is around 75k a year, src: http://content.time.com/time/magazine/article/0,9171,2019628...).
The law says you do. If you want to change that law, fine. But if you choose not to comply, don't complain when you get fined for it.

For what it's worth, just directly measuring changes in gravitational acceleration is much easier and much more sensitive to changes in mass distribution.

We've been able to measure gravitational acceleration very precisely for over a century now.

An 80-year-old LaCoste & Romberg gravimeter will do the job quite nicely, though it's slow to use and you need to know the elevation you're taking the measurement at very precisely. (Interestingly, the ones made before ~1950 are more precise than the ones made in the 60's to 90's. It's basically a very well made and well calibrated spring. When they switched to mass-producing them, the quality fell.)

Now you have a second problem, though... Regardless of whether you've measured things through gravitation acceleration or time dilation, going from the measured effect back to an actual mass distribution is a non-unique inverse problem. There are an infinite number of equally correct solutions (and a larger infinite number of incorrect ones). You can make a pretty good guess at what the mass distribution by applying reasonable a-priori constraints, but there's no single unique way to get the mass distribution from the gravitational effect of the mass.
I've always thought that standing desk need to be adjustable not because you might want to lower it all the way down to use as a normal desk, but rather because without fine-grained adjustment, it's impossible to use the desk standing: a couple centimeters too high or low will quickly make it a nightmare experience.
> Special relativity covers time dilation due to relative velocity, general relativity covers time dilation due to gravity.

It's actually due to acceleration, whether from gravity or from motion. And, given earth's rotation, points on the surface accelerate (except for the poles).

But, as I pointed out elsewhere in this discussion, it's distance from the axis that determines acceleration from rotation, not distance from the center of the earth. (Distance from the center does determine gravity, though).
The web is a terrorist’s command-and-control network of choice
Looks like I need to expand on that a bit. Nowadays we say "Tech is Hell" but it was even worse back in their day and they had a lot of stories about their experience that, them being them, were both hilarious and awful. I ignored their advice because, hey, don't get a teenage boy to not do something by telling him it's hard.
I wanted to share this resource as well.

I started this online free book "Neural Networks and Deep Learning" (http://neuralnetworksanddeeplearning.com/). I think it has a pretty good explanation and illustration.
I am still a Classic Visual BASIC (VB 6.0) programmer.

Microsoft made it so VB 6.0 needed the Microsoft Java Runtime to install and it works with Windows 95 to XP, but in Vista and above it has problems installing. There are ways you can trick it to install but in the long run it is not worth it as it causes OS instability.

I got an XP Pro Virtual Machine in Virtualbox that I develop VB 6.0 apps inside of. GIT only works with XP and up, so Windows 2000 and under are out of the question. (Something about IPV6 support in the Git app and the first Windows to support that was XP so it fails in earlier Windows) So if you want to do legacy Windows programming and use Git, XP is your best choice. Visual Sourcesafe never seemed to work properly and I always had coworkers and management get in and scramble the files by accessing them directly on the NT Server or whatever and load them in MS-Word or MS-Frontpage that changed the formatting and then they saved bypassing source control. At least in Visual Sourcesafe 6 this was true, and I believe that Git is much better.

Since 1983 I have learned over 37 different programming languages on many different platforms. I only did Visual BASIC programming from 1995-2002 because in my area the IT shops were Microsoft shops and management decided to use Visual BASIC. While I knew Non-Microsoft languages, management never wanted me to use them.

I ended up on disability in 2003, and by that time Visual BASIC evolved into VB.Net influenced by Java and took a turn for the worse. Then Visual C# got used because it is more like Java than VB.Net is, and the high schools and colleges teach C# and Java so these new programmers learn it.

In high school I learned Pascal, in college I learned Pre-ANSI C, COBOL, FORTRAN, Ada, X86 Assembly, and others.\

Around 1995 I was learning Java and JavaScript. Then later Python and a few others. But on my spare time at home, because my managers didn't want me to use them.

I just recently took a Ruby on Rails MOOC and passed it with 100% on each programming assignment. I used to do VBScript ASP 3.0 programming. ASP.Net changed all of that apparently.

So yes I am one of the legions of VB programmers out there, got forced into disability, too old to work in my 40s (They only want young people), and read Hacker News because my interests are scattered all over the place in learning stuff.

The die hard Visual BASIC only programmers were the ones I had a coworkers who I had to hand-hold and teach Visual BASIC to them. Most earned university degrees but had no idea how to program. They secret handshaked their way to a job, while I had to pass tests and show code. I super debugged their code, and their code was sloppy and crashed systems and servers. They moved on without me into the Dotnet era and Visual C# and stick to Microsoft websites for their news using Bing as a search engine. They find me on social networks and ask me to apply for my old job so I could help them, but I cannot go back, I can only go forward. Work on my side-projects and do it as a hobby until I can get off disability one day.
Microsoft Band Is a Welcome Surprise in the Wearable Market
FreeBSD is an excellent production server, and I use it all the time. And for "non-hardened" and "protected" production servers, the performance numbers went solidly to FreeBSD for my use cases. Modifying the kernel from GENERIC to something specific to one's needs also helps.

That said, I'm also OpenBSD fan, using it as a "hardened" (Internet facing) production server, with minimal ports, for things like Postfix, DNS, etc. OpenBSD is also well used in network management/control as a router, firewall, etc.

Each has its use case, and does quite well in them.
Could you describe what rights are being violated and the framework in which the rights are couched? I certainly agree that the practice is wrong, but I was unaware of the existence of that degree of specificity in currently-accepted definitions of human rights. Is there a body of case law that is supposed to aid in the interpretation of questions like what exactly constitutes slavery?

The UHDR states that individuals should be free from discrimination, I have no idea what that's supposed to mean when applied universally.

I don't even know what a 'right' is in this context. Are we speaking in the same sense as they are defined in the US Constitution, that governments must respect the laws but private enterprises do not? Or is it meant in a stronger sense, that private enterprises must do so as well, or even individuals? If the latter, how are we supposed to interpret the prohibition against violating a person's free speech rights?

> Education shall be directed to the full development of the human personality and to the strengthening of respect for human rights and fundamental freedoms.

Does this mean that we are now setting education policy across the whole Earth? How strong is this policy supposed to be? Does one class on human rights during secondary school satisfy the requirement?
While the cost of living here is brutal, it seems a lot of people are stuck here due to the supply of tech jobs. It would be a lot more risky to live somewhere that does not have such a supply. As someone with a solid software background, if I were to wake up tomorrow and find myself without a job, I'm reasonably sure that after at most a few months of searching I could line at least something up. If that happened in another city, I'd be in panic mode, wondering how many months of living expenses I had left in the bank account and where my family would be moving to next. When you're not in an area with a healthy job market, it's terrifying to be out of a job without severance, and 1 or 2 months away from bankruptcy (ask me how I know this).
I had no idea rails/django are sooooo slow
Ask HN: Democrat vs. Republican
I came to united states few years back. I like US politics and sort of map it out with things happen in my country. So far I have made few observations and found that on superficial level at least politicians are same.

So what are differences between Democrat and Republican thinking from tax, immigration , foreign policy and vision ?

I also hear people saying liberal vs conservative and there are someone who is independent. So in general there are only 6 major categories to choose ?
Lib-D, Lib-R, Con-D, Con-R, Lib-Indep. , Cons- Indep.
Who you like and what is it like to switch sides ?
Facebook Secret Voter Experiment
Probably should note that Red Hat outfits all staffers with a Thinkpad T series (current gen), and just did a massive refresh of a few thousands of them. T series should "just work" with no fuss. In my experience, T series has always been "no fuss". Can't go wrong with this one.
That doesn't prove anything. You can also export a physics textbook without the issues you would run into exporting a nuclear weapon.
Wow this looks interesting.
You could already add events to somebody's calendar by sending them an invite, and you could already mark events as spam. I don't see what's new here.

Microsoft ends retail sales of Windows 7 and 8
It's actually more than a quarter depending how you define "high-speed broadband". A good number of households in the US are on <6mbps ADSL connections, which realistically aren't fast enough to stream video. Most statistics I've seen show streaming video penetration is closer to 40% of US households.

And you're right about adoption: there are a lot of people in the US who just don't care about the Internet. They will be increasingly less relevant as time goes on (this is already causing social angst at some levels) but they will persist. Usually you don't see 100% adoption of things like this until all the old people die and are replaced in the consumer pool by younger generations (aka generational cyclicality).
Haha, well done. Yes I would have had to look that up.
I'm a PHP developer. Strong Testing skills, good javascript. Very proficient with both relation and non-relational dbs. I'm very active with local meetups and try to speak at conferences every now and then BUT only 1.5yrs working experience. Despite i work my ass off, i'm not at all a senior (nor i even sold myself as one).

I've done exactly 7 interviews for related positions in London and the lowest payed was 45k, highest 60k.

I personally know NOONE in central london ever working for less than 45k. Doesn't really matter if you are a C# dev, Java one, PHP, Ruby or pure frontend. Actually, my closest friends use to work in banking and they make A LOT more than what i just mentioned (70-90k, yet they are definitely seniors).
Are there any deployment notes/examples?
I'm not sure where you mean Redbox prints DVDs. They don't do it in the machine, as popular titles can be "sold out". It was over a week before I could find that last Captain America movie at my nearest Redbox.
I personally believe politeness is an important trait in any political job, and moderation is a political act.

It's a little unfortunate that consistency is only mentioned as a footnote. If this is being used internally at Netflix, how are they dealing with consistency issues in the face of failed or conflicting writes?
In my personal situation, this isn't feasible, because I have a very hard time sitting in chairs where I cannot plant my feet firmly on the ground in front of me. I can only dangle my feet, or plant them underneath me, for a few minutes. After that, my back starts to hurt terribly bad, and stays that way for a while.

I wish the solution was that simple for me. If I were the type of person it would work for, I would definitely go the stool/highchair route over an expensive adjustable desk.
It does, but at least they don't have a conflict of interest from making, enforcing, and profiting from the rules all at once.
Apple hiring for mysterious new engineering office in Seattle
> Keep in mind the very term Silicon Valley comes from chip companies (Fairchild, Intel, etc.) who came to SV because it was cheap, open farm land.

It's funny you mention Intel here -- since the 70s/80s they've continued to expand in Hillsboro, Oregon (a suburb of Portland), where they bought a lot of cheap farmland. It's worked really well for them and the ~16k people they employ in the state. The only downside is a sort of "employer lock-in" for the employees, especially the more specialized ones.
Fun times for devs in HackishWord
NPR and public radio more generally in the U.S. is such a national treasure, and these guys were one of the brightest gems. I loved seeing their personalities and infectious laugh enshrined with a cameo in Pixar's Cars, which itself captured a sort of best-of or hall-of-fame for American car culture.
As i mentioned, i never ever heard of an offer for less than 45k. Which makes sense as you just can't live with 20k in London.
Replying to myself for an update. The hypothesis of a a few users here is correct, while hard to believe. The latency spike is due to the fact that even with the 50 clients of the benchmark, it is possible to touch all the huge pages composing the process in the space of a single event loop. This is why I was observing this initial spike and nothing more. This seemed unrealistic to me with 50 clients, but I remembered that one of the Redis optimizations is to try to serve multiple requests for the same client in the same event loop cycle if there are many in queue, so this is what happens: 50 clients x N-queued-requests = enough requests to touch all the memory pages, or at least a very significant percentage to block for a long time and never again.
Wait until this isn't for parking tickets but rather for Social Security disability determinations or VA mid-term disability determinations or Illinois DOT public right-of-way ingress/egress waivers or...

Crystallized knowledge of how to play the bureaucracy game, in a box, backed up by a pool of people you can grant e.g. Power of Attorney to is freaking brilliant. If it helps, think of it as exposing a web/mobile UI to City Hall without them having to figure out how to do that or upset stakeholders whose jobs are created by Form 213B. Except it is even bigger than that implies.
Yes exactly. This is more or less the ranges i experienced as well.
Since he got most of the tickets dismissed, does that not indicate that he was not breaking the rules is those cases?
From my completely non-finance, non-startup, third-party point of view, I gather some finance workers are able to establish a direct link between their work and their pay ("Your bonus is 1% of the profits your software makes"). Startup workers can only make big money if they are lucky enough to get in on a big exit- their personal performance is only weakly tied to payout.
Will this work with Google cardboard? Occulus is great, but I'd like to use my $25 digital viewfinder instead if possible.
> Not about purchasing power. About the value of money.

The value of money is directly derived from its purchasing power. If you can't buy anything with money, it's worthless.

The point is that the vast majority of the money in the US is in flow, not tied up in the rich 1% bank accounts.

So if 95% of people suddenly have 2x cashflow (on average, let's say) then prices should roughly double within a fairly short period of time. We won't suddenly have more gasoline or milk or beef or whatever if everyone has twice as much money every month. So more money chases the same amount of goods and prices rise. This is really simple economics.

Would doubling the price of everything erode the purchasing power of the rich too? Yeah, absolutely. At least for all the money that they have tied up in cash. But considering that the FDIC only insures you up to $250k I suspect that most wealthy people are going to have their money in assets like stocks, bonds, and real estate. Real estate prices will definitely rise and I suspect that the other asset classes will go up in price too.

There might be a period of a few weeks to a couple of years where people actually do get more stuff before the prices start to rise. But with how just-in-timed everyone's supply chains are these days it's not as though it would take 20 years for everyone to catch up to what's happened.
Actually they should "just use getrandom." Reasons: 1) urandom doesn't block if it's not initialized (that can happen on the embedded devices after the boot) and getrandom does that only then and never again. 2) it provides resilience against
file descriptor exhaustion attacks.

This has been my setup for about a year now. Building a standing-only desk is relatively simple. I built this last weekend in 4 hours for about $50 http://bit.ly/1A6NSlk I use it with this height-adjustable stool http://www.amazon.com/Boss-B16245-BK-Caressoft-Medical-Draft... The stool is comfortable enough, meaning it actually gets a little uncomfortable after a few hours, making me want to stand for a while.
It's interesting you say that. The very next article on the linked blog talks about Blockbuster Total Access (where you could rent online or in stores) taking a million customers a year from Netflix in 2007. Investor Carl Icahn ended up forcing out the CEO who championed Total Access and the new guy sold the membership list to Netflix for $1.4 billion. Streaming might have still catapulted Netflix past Blockbuster, but it would have been much tougher to sign all those content deals without the steady cash flow from DVD's.

Now it looks like Netflix was inevitable, but it took a few huge blunders by other companies for them to succeed. Remember when Starz basically gave away the rights to thousands of shows and movies (for $30 million/year)? We could just as likely be talking about Viacom Streaming and all those silly things that Netflix did.

You're entirely correct, and I'm going to modify my answer to a convenient lie (in the true style of a physicist).

The point stands, but now I'm interested in what kind of cones we could make where relative heights and latitudes yield identical velocities. Prolly as useful a question as most XKCD What If? notes :)
