This is a bit confusing to me.

From the article
"Rather than just use the accelerometer to count steps, the Band combines that data with your phone’s GPS data and the always-on heart-rate monitor to figure out the length of your strides, which provides a much more accurate measurement of calories burned."

If there is on-board gps, why does the MS band need gps data from the phone ?

I think you still have the same problem, just more uniformly distributed. Imagine a dome shaped panel. No matter what the orientation relative to the sun, the panels are equally facing it. But even still, any particular point in the dome has an orientation and it's only ideal while it's ideal. The point facing east is ideal for sunrise but is useless at sundown. You get as much uniformity as the sun and clouds give you, but you're equally wasting the same amount of panel face at any given time.

Heavy use of client side methods seems to break a lot of the benefits of using web apps in the first place. A main advantage of web apps originally was that they worked more or less the same on any machine. That Google Maps worked in exactly the same way regardless of how good your machine was at vector rendering. I wonder if the aversion to maintaining state on the server needs to end. You could do almost anything that a modern web app does with minimal client side code and have performance on low end PCs.

Where things gets interesting, is when you realize you can manipulate the other person's orange through your own view. that realization comes with the fact that consciousness, I believe, is shared across all living beings.

My experiences with my own practices indicate that these closed off views are indeed not closed off. be aware, that my practices involve the esoteric and the occult. Many people are not comfortable with these discussions and will actively refute any merit whatsoever. Interestingly enough, I do my own semi - scientific theories regarding the occult, only that N=1, me. And I also have to acknolodge that my own sensors also can actively deceive me (placebo).

I've given up on proving this or that phenomenon within an esoteric background. Either you practice and have seen these things for yourself (and another N=1), or you haven't.

~95% iirc assuming 'perfect' cells. There are some very impressive triple layer panels out there that do 44%+ right now, these are typically used in space applications.

The balance between incident radiation and power produced is an interesting one, a 'perfect' solar panel would remain cold. Solar panels tend to produce less power as they warm up, so the better a solar panel gets at converting power the less it will get warmer! So there is a positive feedback mechanism at work here.

Typical run-of-the-mill cells are 25% (single junction), and on cold clear winter days they can keep that up for quite a while. So that's 250 Watts per square meter of panel.

I did some simulations to figure out the exact gain you could get from perfect seasonal and day tracking, it's about 28%, but no tracking system will ever reach that in practice. Typical reasons why you won't get to perfect: tracking systems tend to hunt the clouds if they are not clock based, otoh if they are clock based they tend to perform badly because they use energy to move when they're not producing energy themselves!
I used to think so too, especially because very basic examples with `printf!()` look "odd", but I started to like it: it gives me confidence that regular function calls won't do anything bizarre.

It's a warning that there's "magic" going on. It makes it clear that there's a lot of quirky compile-time type checking trickery behind printf, it tells that regex is going to be precompiled, etc.

This is incorrect. I can't think of any macros that are used to paper over the lack varargs (`println!` certainly doesn't count, because even if Rust had varargs you'd still need a macro here to do typesafe compile-time string parsing).

In any case, varargs can already be trivially emulated using vectors (which afaict is essentially what Go does, but Go has sugar for it). Macros would be overkill for this use case.
That's not really a sensible association. A lot of work is done with those languages where shells are either not used at all, or are just a development tool (e.g. could be replaced by editor features). It seems rather strange to try to forcibly connect Python/Ruby/... and sh, rather than just grouping as languages that happen to share the # for comments. (Maybe they adopted it from shells originally, but the languages definitely stand on their own now.)
i never assumed it wasn't the case.

Don't your arguments (and app recommendations) point against a UV measure as being useful? If you want to know whether or not to put on sunscreen now, for a day out, knowing the current UV strength is no use since the conditions will be different later. That's where weather prediction comes in and makes your one little watchband UV datapoint useless. Looking up at the sky and observing weather conditions will always be better than that, and better weather prediction will beat looking up at the sky.
The problem with backslash is that it's already used by the JSON parser. If you happened to have a key `\/`, that would need to be written "\\\\\\/".

We're definitely in agreement there. The main criterium is: use what you know how to use. So if you're comfortable using the MS stack then go for it, otherwise, probably better to avoid it.
I've implemented an API against this and think it's pretty good.

http://microcosm-cc.github.io/#conversations-single-patch

We didn't implement the entirety of the standard as our resources are fairly small and simple and it would have been overkill.

The scenario we had is that we needed to take a set of changes to a resource, but parts of the JSON document are permissioned differently. i.e. You might have permission to change the document body, but not some audit trail meta data returned as part of the resource.

Treating patches as a batch of operations to be performed on a document (usually within one transaction) is a good way to do the processing for this scenario.

I know that there are other approaches, such as calculating a diff and just sending that... but describing operations does make the system less fragile and does make it easier for scenarios like the one we had where you could not assume that the entire resource is under a single permission structure.

Nah i mean in Japan i buy a credit card sized card. It is waterproof and I don't need to take care of it in any way. It has no battery, it does not stop working when dropped. It can stay in my wallet (just swipe the wallet) and you can buy small stuff with it (public transportation, corner store, supermarket, electronics store etc...).

I called it retarded to put the exact same technology into something that is heavier and prone to more defects.

The downvotes are plain silly because putting the same tech into a cellphone, while technically feasible, is inferior to those cards in (almost) every way. The only benefit is recharging over air or direct debit from your bank account. They should rather allow me to charge the card itself with the cellphones NFC.
This might seem like a minor issue but it annoyed me like hell. At that point I knew all I was seeing were the visions of a drunk marketeer anyhow, but at that point I realized that they weren't even bothering with reality.

In an area that reaches extreme UV indexes I would find it useful to know for a for a given start time in the morning and the afternoon how much time I have before burning for the conditions on the day.

UV forecast graphs take some of the guesswork out of location and time, but I find that it hard to judge how much cloud cover is needed to drop from a high to a low index range. Sunscreen is great but it's not much fun to have to be covered in goop every day. Getting burnt when it's cloudy isn't much fun either. Knowing your exposure would limit the amount of cream.

You did not get the point. Ofc there are many binary protocols available. However in the RFC's and standards one chooses to couple behaviour and textual protocol.

Ah, very good point I didn't think of that. I suppose it could function as a warning system. You're go out in the morning and it's cloudy and suncream isn't required. As the day goes on the UV levels increase and your fitness band can warn you that you should think about applying suncream as the UV levels have increased.

Can AngularJS Maintain Its Dominance?
Simple/crude estimate:

Sunlight per m^2 of static solar panel is Cos[x] - x=0 at midday, x=-pi/2 at sunrise.

Static panel total daily sunlight: Integrate[ Cos[x] ,{x, -pi/2, pi/2}] = 2.

Moving panel total daily sunlight: Integrate[ Cos[0] ,{x, -pi/2, pi/2}] = pi.

Ratio = pi/2 = 1.57.

So a 57% increase in daily power, in theory, near the equator.

But - I have ignored atmospheric absorption - at sunrise, the light goes through more atmosphere to get to your panels - I don't know how much this matters. On slightly overcast days, this is presumably very important - how cloudy is it where you are, in theory? :)

Also, you get power from scattered sunlight. Very roughly it is 10% of your panel's rated power, even when it has no direct sunlight falling on it. These 2 effects reduce the benefit of tracking vs static.

When I was looking at making my own tracking system, I found a Canadian company that claimed (iirc) "30% gain" for their tracking system. I thought 'only 30%, it seems hardly worth it?' (Except for load-balancing reasons).

Other stuff: Most domestic panels are on roofs - they are often not 'ideally sited' - e.g. do not face due south, roofs not steep enough.
Ask HN: Concept for a call anonymization setup similar to TOR
I've been tossing around an idea tonight about a service that could anonymize phone calls in sort of the same way that TOR anonymizes internet traffic.
The basic set up would involve a lot of asterisk boxes hosted all over the world that would blindly route phone calls to other asterisk boxes before eventually completing the call. Only the first box would know both the original calling number and the number to be called and I'm sure there's a way to make it so that only the last box in the chain would know the number to be called without informing any of the other intermediary boxes in the chain.
You could clear the call logs of all the boxes at very short intervals say every 10 minutes or even as soon as the call is passed on to the next box in the chain.
Your local phone service would only be able to track your call to the first hop in the chain so it would be basically impossible to tell who you were really calling. I could see this being useful for leakers, hackers, and of course criminals would eventually find plenty of use for it. That's not really any of my concern.
Something like this wouldn't even be that expensive with VoIP prices what they are these days.

Do you think this is a reasonable/viable concept? Do you think people would pay for a service like this?
Can you think of ways to improve this setup?

If anyone is interested in talking about this further, beyond just HN comments, you can email TeleTorDiscuss@gmail.com

This is all sort of back of the napkin stuff guys, so please try to keep criticism/critique civil. It's early and I legitimately had this idea in a dream.

Being in such a progressive community (i.e. young nerdy people), it's easy to forget that this is an enormous deal for some people.

In most jurisdictions the prosecutor entirely controls whether someone is indicted. The prosecutor has the sole ability to present fact and evidence to the grand jury. There is no defense attorney allowed to speak. Thus the common saying amoung prosecutors that they could "indict a ham sandwich for the murder of a pig."

But while the act of being indicted means very little the evidence it forces the prosecution to produce is essential to the defendant.

The documentation produced by the indictment contains testimony, evidence, and large portions of the investigation. It's almost always the defense's first target of attack. However, in this case, it appears very solid for the prosecution.

If I were Ulbricht, I would hammer at the potential Fourth Amendment violation. It is still unclear how the FBI located and imaged Silk Road's servers.

He's put filed motions, but his lawyers never did the investigatory legwork needed to win. Winning such a motion requires a very tight focus on the particularities of the case, and so one can see the smallest of violations, like tiny pinpricks of sun through a brick wall. Then you take one of these pinpricks, and you turn it into a defense.

I would ask, in no particular order:

How exactly did the the FBI get the images of the Silk Road servers?

What is the timeline of the various events in the investigation leading up to Ubricht's arrest?

Did the gmail screen name lead them to the Stack Overflow post which led to the MLAT, which led to the server?

Or did this, as they said later, somehow "expose" the Silk Road IP, and back track the rest of the evidence.

Were any other intelligence agencies involved?

Was any form of backbone collection use to reveal the SR IP?

Mainly I would do this, because if he doesn't win a Fourth Amendment motion to dismiss he's going to jail for a very very long time.
