Ask HN: Future course of Ipad ordering app development
Hi Hackers,
I have been working on a ipad Restaurant Ordering app for the restaurants that i have a few customers for as well and is very well received by them. I have tied it up with wireless printer support and credit card payments with the partnership with payment company as well. However in light of the competition entering this field im getting second thoughts everyday on if i will be able to take it from part time to full time ever (would need funding from someone to do that because of visa issues). Since i have seen so many competitors in the last months on this im not able to charter my growth with this except have it as a part time project. I want to take it to a bigger "national" scale.
Any suggestions on what i should do ?
I altered the title from "money" to $, because the max title length is 80 characters and it went over that, so I had to hack down a few words.
This is unfortunate, but it mostly applies to built-in types (since they don't have a declaration anywhere). Types that are defined entirely in libraries do have their trait implementations explicitly listed, e.g. http://seld.be/rustdoc/master/extra/dlist/struct.DList.html#...
(1) CA is much better positioned to straighten out the land use issues. It needs to use the existing I-5 right of way, it needs to tunnel through some mountains, and it probably needs to eminent domain some additional bits of land for pylon bases where I-5 curves too sharply. No matter what, this is a project that has to pass the legislature in order to get built.

(2) A CA-sponsored bond issue must be by far the lowest cost way to finance a $7B infrastructure project that's amortized over 30 years.
The article and your comment are misleading. Despite the professor's calculation, it contradicts other evidence including the eye witnesses.

Michael Krikorian observes that Hastings' car was going at least twice as fast as the other cars in the video. He estimated that the car was travelling at least 80 mph.

And the video from Loudlabs' clearly shows Hastings' car speeding through a red light prior to the crash.

And in the Krikorian article, a special effects expert said the bright flash of light could be due to the auto exposure of the camera causing the explosion to look bigger than it actually was. The "pre-explosion" appears to be the car hitting the 30" x 2' wide metal protusion for a water main between the curb and the tree.

And the expert noted that a bomb would blow the car and engine upwards and not forwards.

> ... that doesn't seem to have held Google back.

To the contrary. Google's map data in Belarus also comes from volunteers. For all we know, most of the volunteers who supplied the data for Google Maps and OpenStreetMap may also be working on Nokia Maps now.

The problem they are attempting to solve is that Nokia maps does not have Belarus map data. The fact that Google and OSM have that data is useless to Nokia, and to all GPS device companies that license from Nokia.

The incentive for these volunteers is that in a few years, they'll be able to tell a visitor, "Just enter the address into your GPS," knowing that it'll work. If they supplied the map data only to OSM and withheld it from commercial organizations like Google and Nokia, then they won't be able to accomplish that.
Ah, that's boring. Look, we're talking about progress here, no Government burocrat should be able to stop us. Just $1B extra in "fees" would get us all the Government backing in the world we want. Unless we're not really serious about the whole thing and not really confident about the end result.

Or just have Jobs resurrected. This way we save $1B on the "fees" and he'll talk the Government officials into this for free. They'll think they get the best deal in the world once Steve is done talking to them and the Distortion Field is permanently present in the Government heads.
Yeah. Adult diapers! Problem solved.
This is addressed in the document. Essentially, each station is a terminus, so airlocks are transited at low speed. A turntable reorients trains for their next trip. The only switching required takes place entirely within the evacuated zone. (This is for when spurs are built to serve e.g. San Diego or Las Vegas.)

This threw me off as well.
Also, I wonder what HSR incidents he's referring to. The Spanish relatively low-speed human error crash? Systems like Japan's Shinkansen have never had a fatal accident, despite operating at the edge of technology for 50 years. I don't think a derailing accident is at all likely on a modern system like California's plan or the UK's HS2.

How many people have a picture with their contact information for friends and family? My guess is a metric fuckton. Since they're allowed to access "contact information" then a few cross references of a different picture of you along with your name and phone number should be more than enough to add facial recognition data to your shadow profile. They can already guess who is in a picture of your friends. Why would this be any different?
Just as an anecdote.. We had some friends from Orange County come visit us in SF this past weekend.

* OC -> SF -- Left at 3pm, took 9.5hrs to drive
* SF -> OC -- Left at 9pm, took 7 hours to drive

There is random night construction as well as detours and traffic to worry about on I-5. Half an hour would be a no-brainer, even if it only went so far as downtown LA.
Best of luck, I recently received an email that WorkforPie.com was shutting down (http://thenextweb.com/insider/2013/08/02/developer-hiring-st...) and they had the same sort of model.

I get we always complain about the developer interview process, but are these business models actually solving the problem?
I thought it was just a few days ago that elon musk said that he "wished he had never mentioned the hyperloop as he doesn't have enough time to work on it" [sic].

When I heard the news about this announcement on the radio today, I thought that my local news station was just a week behind the times as usual. Apparently they were not?
What will probably happen is that you get a transparent car and advertisements on the inside of the tube.
Yes. However, I believe Facebook has a history that shows it repeatedly failing to be trustworthy enough to make those decisions.
Fair enough, I've never looked into it and he gave it as an example of a Microsoft project.
I'll just leave this here:

Looks like I nailed most of it. So, who is going to build a proof-of-concept scale model of this thing a few kilometers long?
What disadvantages do you perceive for PDF?
You are correct, I am begging the question, the DOJ are investigating the question. Maybe they will find the DEA and SOD are acting illegally. Hopefully they will. Those who would defend the use of NSA data for domestic crimes are dangerously close to advocating for a police state.

I may have written that quote and edited out because it was wrong. Sorry about that.

I doubt I am mistaken about the poisoned tree though because a source of evidence that may have exculpatory evidence is being obscured. It may also be acquired illegally but that is obscured too.

Implicit in your reply is an admission that the NSA tips are being used.
"people aren't being snatched up off the streets because of the NSA's monitoring programs."
Do you still stand by this because now there's evidence presented to you that the IRS and the DEA have access to NSA tips through the SOD?

A statement from the NSA:
"If the intelligence community collects information pursuant to a valid foreign intelligence tasking that is recognised as being evidence of a crime, [it] can disseminate that information to law enforcement, as appropriate."

I think your example of NSA tips is rather convoluted, I prefer the NSA's statement above as it's pretty clear and leaves little to the imagination.
Cows on I-5. Greatest benefit is it's an enclosed tube, odors not allowed.
Although Musk has said this idea stems from his frustrations in traveling through California, I wonder if he's contemplating something similar for transportation on Mars?
the "loop" is likely at the end of each line so the pods can turn around.

Interestingly, my DC Metrorail trip to home or work takes between 45-60 minutes one-way... and there are no facilities on the train itself, and very few stations have any public-accessible facilities. "Holding it" has honestly never been an issue, you either go before you leave, or sack up and wait until you get home. Worst case is probably that you get sick en route and well... that alone wouldn't wreck Hyperloop.
So you confirmed that every local search goes to MSFT servers? It is default, isn't it? And it's hard to turn off? You mention group policy -- I know that tool and it's harder than "just change in the registry" which is far from easy for plain users.

That's really, really bad. Local search sent to MSFT by a hard to change default is crossing the limit IMHO.
Show HN: My New App for Building a Roadmap
This debate isn't about online ads or even spam anymore.

I actually like to see good ads online too and often find them useful. For most people, trading some data for better ads and free services is a deal that they're willing to make - most people don't have the mentality of RMS. I might be willing to trade some data about myself voluntarily so I'll see some ads about products I might actually buy instead of ads for viagra and other penis-related things.

What Facebook and Google is doing here would not be nearly as troubling without this NSA data collection stuff. As annoying as online advertising can sometimes be, generally that information that companies gather about people from online ads isn't going to wreck anybody's life in any serious way and there are always ad-blockers and things to use to limit that if a site is annoying you.

But if the NSA's algorithms use some random meta-data and Facebook likes and search keywords to somehow determine that you're a potential "terrorist sympathizer" or something and you get placed on some no-fly or watch list with no recourse, that can put your livelihood or ultimately even your life in danger. We don't yet know the full extent of these programs or how the data is used and I'm not trusting the same politicians that hid this from us and lied to us and have always lied to us for more power.

The groundwork is in place for the next politicians that come into power that are unlimited by ambition to create a nearly perfect political dictatorship. This isn't a situation we should be in.

I am the lead developer on Aha!. We built it to help product managers and developers collaborate on features and roadmaps. We have been working around the clock (well, almost) for the last few months and today we finally allowed open signups. We ran a private beta (http://blog.aha.io/index.php/great-beta-programs-a-contraria...) and got lots of great feedback from a group of really engaged users. This was a big change from my previous startup where we ran an open beta and had thousands of users, but little useful feedback.

I have been writing Ruby on Rails applications for a long time now, but it was a real pleasure to start from scratch using the latest version, and all the wonderful gems that are now available.

We wanted the UI to feel really responsive, and to allow almost real-time collaboration by multiple people. The underlying technology is Rails, with as little Javascript/CoffeeScript as possible, but with extensive use of Faye (http://faye.jcoglan.com/) to enable real-time notifications between users, and also to update the screen of the current user in response to their own changes. This allowed us to focus more energy on the Rails backend, and put all the business logic in one place without giving up the real-time user experience that a Javascript framework provides.

Between Faye and Rails' Turbolinks, I've been really pleased with how easy it is now to get great performance out of a Rails app.
a type system of sufficient power can express your program just fine so long as you declare to the type checker that you're not just making a silly mistake

Sure, if I know in advance what types I want to mix. But suppose I don't? Or suppose I start out with one type mix, and then discover I need to change it? With static typing, I have to do a custom type declaration for each mix, and keep it up to date.
Can't (1) and (2) be solved by additional $1b to cover "cost" the Government might have? Just make it easier for them to move it through legislature, mountains, and such ;-)
> and it's very possible a lead from an intelligence agency was instrumental in their arrest.

So you have no clue, do you?

The NSA is on your side when it comes to international threats. If you decide to break the law, and they find out about it, that's a different ball game.

Pro tip: don't break the law.
I'd love to know what James Hague (http://prog21.dadgum.com/) thinks of Elixir. Erlang is one of his stronger languages, and he's written a lot of articles in the past that I really enjoy.
Any research in concurrency is a good thing. The massively parallel program model that I want to know more about is IBM's TrueNorth.[1]

None of the articles I've found had any substance, but the it was fitting that hardware diagram[2] looks very similar to Bret's "vision from the 70s" :) [3]

Heh, true. However, this short essay contains more useful actionable advice for HN readers than is typical even for PG, so I hope it doesn't get overlooked. Very very impressed, here.
Agreed ANY project will require government support. I just don't see many governments supporting competing projects. So if CA HSR gets built competing projects, such as Hyperloop, are unlikely to get the required government support. Make sense?

I'm 30. I know so much more than when I was 23. There is so much more I don't know still though, and I recognize that now (not so much at 23).

Passion comes from fulfillment. Find what fulfills you.
If I read it right, the movement is absorbed by shock absorbers that need to be installed for earthquake protection anyways. You just need to make sure that the segment between the lateral movement/shock absorbers are sized such that the differential thermal expansion doesn't violate the deflection requirements.
Well, I'm not a special effects expert but I would assume a bomb placed between the engine block and the firewall would indeed push the engine forward. One placed beneath the engine would seem to push it upward. Until placement (big if on placement in the first place) is determined, it doesn't seem likely to be able to explain the results.
Just like in Windows XP/Vista when you configured the updates to always be manual? Yeah, except that Windows is their OS and your settings are just guidelines ;)
I don't really believe your claim without you providing any pointers as to where I am supposed to be wrong. I have been following that feminism thing for a while now and I don't think I am that misinformed.

Of course feminists themselves see themselves in a different light. They think they are warm, saintly, compassionate beings who want nothing but the best for all mankind. They don't really question what they are doing or what cult they have joined, though.

It is true, I have concluded that I am really anti-feminist, after watching the movement for a while. As I explained above, obviously that doesn't mean I am against equality. What I am against is the ideology of painting women as victims. Also the ideology seems in many parts damaging to women, for example it pressures them into working instead of spending time with their families (they should have a free choice), it is against extra pay for stay at home mums, it scares women by creating a completely overblown rape scare and so on.

As I said, if you can point anything where I am wrong, I would love to hear it. I will also take a look at your book recommendation.
Aérotrain is not magnetic, it uses air resistance too. Read the link, ahem.
The distance is just about what I commuted on a bus for many, many years, also with no facilities.

In peak hour it would probably be fine, when everyone is fairly sensible and not drunk. But after hours, I've had quite a few uncomfortable bus rides due to the various anti-social behaviours of fellow passengers. That was with the hand-brake of a driver who obviously isn't getting involved, but can avoid escalating behaviour by stopping the bus or calling authorities.

I have great faith in the technology! I just wish I had as much faith in the people riding inside it :)

I really doubt the steam tank will be inside the pressurised volume. If they fail they would vent overboard. While an explosive failure would probably cause problems it wouldn't expose the passengers to high pressure steam.

The failure mode for composite overwrap pressure vessels is a slow leak, due to the overwrap containing the metal.
Can someone point to a link which explains the math of startup fund raising? I was thinking about it, and what I get is a paradox:

I assume the definition of raising money is that the original owner gives some percentage of the company to a new owner, and the new owner gives an amount of money to the company.

Let's say the company's valuation is 1 million dollars.
Let's say the owner sells 10% for 0.1 million dollars.

In a perfect market the company's new valuation is obviously 1.1 million dollars: the original value in the company's resources (people, etc...) plus the 0.1 million in the bank.

On the other hand in a perfect market perfect owners made a deal in which the original owner's wealth is the same before and after the deal.

Before the deal he was worth 1million.
After the deal he is worth 0.9*x, where x is the new valuation of the company.

So:

1million dollars = 0.9x

x = 1.1111' million dollars

So which is the correct new valuation: 1.1, or 1.1111'?
Or something different?

Maybe the deal have to be made in infinitely small pieces, so the result is coming from some kind of differential equation?
It's weird, there was a (stupid) debate on HN a ~month ago about whether cars "explode" the way Hastings seemed to have (it smoldered on despite the photographer who pointed out how much more violent the flames would have seen due to nighttime videography, and despite the EMT who posted his experiences dealing with car fires, and despite the posted video of a car almost literally appearing to explode when it ran into a tollbooth).

And anyways, what's weird is that since then I've driven past two horrible vehicle fires. One was on the west side of Chicago, a high-end Lexus on the side of the road roaring with flames as if someone had thrown a grenade into it. The other was a semi driving on the inbound Ike --- driving lazily across 4 lanes of traffic while burning so violently that little flaming chunks of it were flying off it and bouncing off the road in front of me, so hot that it was actually uncomfortable to drive past it (what else do you do?) even with the windows shut and the AC on.

The people who say it's implausible for routine circumstances to cause a car to burn violently don't know what they're talking about.
Also, they can go around killing anyone they don't like. That doesn't mean we should approve or shouldn't advocate laws prohibiting it.
The intelligence community doesn't ignore senators and representatives. That isn't happening except in a political fantasy world where being opposed to the NSA is beneficial.

What's naive is believing that you have enough information to make a decision about whether or not the NSA is effective at what it does, or that you have enough information to determine that US foreign action is why we're being threatened.

You elect representatives because there is no possible way to inform you about everything. This is not a direct democracy for many very good reasons.
What's lost in absolute $ terms is (IMHO) more than made up for by being known as the early bird, which status will yield other opportunities. In game theory terms being early is not optimal in a single round but close to optimal in the iterated competition that more often prevails.

With that said, it's not hard in this case to C&P to something more suitable for GitHub and really get things kicked off, but LaTeX would be more suitable.
