I don't see how push notifications would be any better than e-mails in this scenario - you already get e-mail delivery notifications anyway, so it fits in your existing workflow. They're also archivable - you're unlikely to act immediately on a notification from Luna. It makes more sense for it to sit in your inbox until you're at home/whatever.

As for the app being on the home screen, sure. But how often are you going to be looking at your phone and think "ooh, I'll use Luna for a few minutes"? Never. It doesn't need your attention that way. You'll open it when you get an e-mail notification about a delivery. I guess the core of it is that there's no real need for Luna to be an app at all.
I wrote up a blog post a couple years ago about how to integrate PubSubHubbub yourself.

That blog post includes what to look for in the RSS feed and how to subscribe to updates. It's written in Python, but that's just a short-hand way of saying it's in plain english.

It also includes details on how to then push the real-time updates out to clients using JavaScript and Socket.io.
I think that if you need the product to increase the amount of workable hours in a day, you're doing something wrong to begin with. The idea of Polyphasic sleep in itself is interesting, but do it for the right reasons (more time to communicate with friends/family who are in a different timezone, work nightshifts etc.).

One other thing to consider is the fact that sleeping less means you've got more time to spend, also during hours when almost nobody else is awake. For some this isn't an issue, but for others this could prove to be difficult. I for one would opt for an Everyman cycle, since it allows you to be awake during relatively "normal" hours.
> Contruction is used to derive a right to representation under the equal protection doctrine of the 14th amendment.

Well, no, Gideon found that the right to counsel found in the 6th Amendment was incorporated against the states by the Due Process Clause of the 14th Amendment, not the Equal Protection Clause of the 14th.

But, sure, its a bad example of a right not enumerated in the Constitution, since the right to counsel is a right expressly enumerated in the 6th Amendment (and not, there, expressly limited in applicability to federal cases, though that's the way it had always been applied), and the prohibition on deprivation of due process by the states is again expressly enumerated in the 14th Amendment.

Ask HN: How to apply the hard learned SMS/SIM internals in Startup?
Hello HN,

Last few years I have been developing SMS (binary SMS)-as-a-Service applications, in python and java eco stack, where I've learned the internals of SMS (3GPP TS 23.040) and SIM cards security(3GPP TS 23.048). Now I've allocated 30% of my work week to work on something new, something challenging on my own by mixing this hard earned knowledge with other different domain.

According to technology radar 2013 (http://www.thoughtworks.com/radar), there is a need for SMS/USSD UI for applications. Problem is that its very hard to choose a domain where I can apply SMS/SIM knowledge. I need a different perspective from you guys. Please do share your different views of applying it. Maybe I could find a business co-founder here.

Here's the response from Prezi http://engineering.prezi.com/blog/2013/12/03/a-bug-in-the-bu...
I doubt it'll be that bad. This new behavior is how .NET has done it all along, and out of all the mountains of code I've written that loop over the words in a block of text I've found exactly one situation where benchmarks showed it was worth worrying about. Not for lack of looking, either.

I'm inclined to think that Java's old way of doing it is an optimization that largely became obsolete when the HotSpot VM came out over a decade ago. The nature of generational garbage collection means that the way this method ends up using memory in practice is rather different from what one might expect at first glance. Combine that with modern CPU architecture and it might even end up being faster because of better cache-friendliness.

Why use cover text? Why not just put ciphertext in a jpeg? Wouldn't that just show up as noise?
Great one! I sent a bunch of people who asked how to get started into that direction :)
What I'm saying is if you can't find employees at the current wage you're paying and increasing the wage means the employee is no longer worth it than you have the right amount of employees and there is no shortage. Companies aren't entitled to employees or entitled to be in business. Just because you can't afford something doesn't mean there is a shortage. But companies who are in this situation complain that there is a shortage when really they just can't afford the employees. All I meant was that I was annoyed at the constant talk of 'shortages'.
When you work for a company, like our client Procter & Gamble, they will present you with a problem. “Here,” they will say, “is our problem and a big bucket of money. Please create a solution.” There is no need for guessing.

Ummm i want the best of both worlds... how can I (a person with no contacts in the company) go to procter & gamble, and say "hey I'm pretty good at tech, let me solve your problems"?
I felt that way a little bit, but since I already knew the physics (and heard of a similar system that uses a microprinted array of spikes (conductive spikes naturally create a charge separation when pumped to a voltage) I wasn't put off by it.

The background is the availability heuristic. Parents demand schools adopt security measures to thwart "stereotypical kidnapping" (~120 cases in the U.S. annually) when the gravest dangers children face are riding home in cars (~200k injuries annually) and obesity (20% of all U.S. children).
Yeah... but is scaling down the 'single big rotor' mechanisms used by real helicopters that difficult? would it be more expensive than developing a lightweight electric battery that could give you the same range?

I don't know the answers to those questions; I'm just saying, if range is the problem there are solutions that don't involve breakthroughs in battery technology.

The arbitrarors list is a problem. It seems to suggest that they're all trustworthy, so if your seller just says 'ok lets go with this guy' you might just accept. Then it turns out it was a dummy account created by the seller...

To be useful this would really require a separate service with a reputation system, perhaps a check saying if the arbitrators identity was verified, required pgp etc.
I think the GP is confusing 6.4->6.5 as a major update, when it's a minor update.

The due process and equal protection clauses don't mean that "people should get educational services for free". It does mean, however, that if the State generally provides these services for free (and, a fortiori, if it, as many states do, adopts a right to such services as a State Constitutional guarantee), it cannot arbitrarily discriminate in who gets such services.

(There are also federal statutory requirements that come into play if, as I believe every state does, states accept federal education funding.)

>And for a lot of that stuff you're not going to know ahead of time if someone is going to send it via USPS or UPS or FedEx because it'll go whichever way is cheapest. //

Perhaps it works because you can't send it to them by USPS so they'll never be the cheapest route.

Presumably when Amazon, say, are sending out an item they arrange the collection using some form of API and choose the optimal (by price I expect) delivery route. USPS would simply not be listed and so Amazon would route to Luna as expected.

Maybe it doesn't work like that, just a suggestion.

Imagine you have 10 people who listen to artist A once every month and one person who listens to artist B 90 times.

Under the current spotify system, artist B would get 90% of the revenue and artist A would get 10%. Under the parent's proposal, artist A would get 89% of the revenue and artist B would get 11%.

In any case, I'm willing to bet that the parent's proposal would actually backfire. I would wager that people who listen to obscure music also listen to more music so they're actually receiving more under the original spotify proposal.
Now that html5 is a thing that would definitely be doable.

> There are incentives for teachers to help talented, excelling individuals who have no problems. It makes the teacher and the school look good, especially for local and national government programs that reward teachers/schools with good results.

The incentives are actually reversed in the era of NCLB, where the most important measure isn't how good the best results are, but what proportion aren't meeting the minimum standards for their grade level. This provides incentives to:
1) Improve the performance of the worst performing students if it is cheap to do,
2) Get the worst performing students out of the system if it is not cheap to improve their performance,
3) Avoid accelerated promotion of students that are performing at a higher grade level and not challenged, so as to make the percentages look better.

> Actually, there is one incentive for teachers to help troubled kids: High school and college sports. The sports brings in the money, and so they need to make sure the kids don't completely fail out so they can keep bringing in the dough.

As I understand it, for the most part, high school and college sports bring in money (if at all) for the sports program, not the school at large.

This doesn't really contradict your point, but I was more thinking about the arc from 'small to huge', not the arc from 'huge to ginormous' -- after all, how did Vanguard become the leader in the space? Honda competed on price and efficiency to secure government industrial contracts; for Vanguard's first five years its only investors were institutional[^1], where their success laid much more in being a (massively successful) niche fund that no other firm offered than having any household success.

Other commenters have argued that repeated success in an RFP environment comes from reputation (and thus word-of-mouth), but I think that's stretching too far from the original thrust of the article.

[^1] I read this in a book but Wikipedia says that its first index fund in 1976, was available to individual investors, so I'm not 100% on this.

I found it useful to use Chrome's USB API to create a viewer to connect the Oculus Rift with remotely-hosted WebGL apps: https://github.com/DanAndersen/cupola

It lets me feed in head-tracking data from the Rift, while avoiding the latency that you'd get from using something like WebSockets. I'd use something like vr.js, but that's an NPAPI plugin and Chrome is retiring those.

Unfortunately Windows-only (and maybe Linux with some adjustment) so far, since the USB API doesn't yet properly work with HID devices on OSX.

70% royalty share was imposed by the majors to Spotify. Just because this was the model used by physical stores and it's how the industry works. They didn't change the revenue split model.

One of the problems here is that there are many middlemen involved between the artist and Spotify. The label, the manager, the aggregator. Everyone gets his piece.

Also, there is problem regarding how much it takes for an artist to get the same from Spotify than they used to get from a song sold from a service like iTunes. Some artists claim that a song has to be listened up to 60 times in a streaming service in order to the same as a song sold in a digital music store. And here there comes the big issue. Have you ever listened 60 times to a song you buy in iTunes.
So what you are saying is that the bill of rights itself lays out a recipe which tells polticians what to start regulating and limiting to get themselves more power to turn the US into a tyrrany.

My experience with government contracts differs from that. Most of the contracts we get are because we have worked with the Contracting Officer previously and had done good work, or were introduced to them by a mutual contact. Of course that's just my experience, and one anecdote does not make good data.
Going to a UPS, FedEx, or USPS location to get a package can easily kill the better part of an hour just doing it, nevermind the wider effects of any interruption.

Meanwhile, one delivery guy can probably handle 10+ deliveries an hour. One guy can easily save us a work-week every night.

The guy who delivers lunch to a company can be delivering the lunch of 100+ people every day. Even if it only saves 10 minutes per person, he's just saved 16 man-hours.

The diagonalization argument has always bothered me, this is why.

Countable sets are shown to be countable by providing a mapping between the natural numbers and that set. Uncountable sets are shown to be uncountable by assuming they are and creating a new element from the set of all elements and showing that it was not accounted for in the first place.

But what happens when we try to use the mapping argument on the set of the reals, and the contradiction argument in the set of the integers?

For the countability of the reals, I can setup a binary tree of infinite depth with 0 on the left and 1 on the right. I then do a depth first walk of the tree and assign an integer to each of the nodes. Then the sequence of 0s and 1s from the root of the tree to any node we care to go to represents a binary number between 0 and 1 if we treat it as a binary fraction like he does in theorem 16. So any number we care to go down to in the binary tree can be assigned a natural number, and since the binary tree is infinite it can go down to any real number. So according to this argument the reals are countable.

Now for the diagonalization-like argument for incountability of the natural numbers. Assume the positive even numbers are countable, and that we have a list of all the even numbers assigned to a natural number. I can create a new even number by adding all of the numbers in the list, since all the numbers are positive, each number is smaller than the sum of all of the numbers on the list, so the number is not on the list, and we have to conclude that our assumption was wrong, and that the even numbers are uncountable.

If the first argument is wrong, why is it wrong for the reals but not wrong for the naturals? And if the second argument is wrong, why is it wrong for the naturals but not wrong for the reals?
