I think btilly is proposing a new sort of price - some kind of time-varying, smoothed average of the last trade and orders in the book - distinct from any of the current notions of price.

The critical thing is (I think) the concept of price takes time to move, making it possible for use the liquidity that exists without HFT, but still letting HFT cover the gaps.

For the example below, we suppose this new price can only move $0.01 a minute (obviously real thing would be more complex, but this makes things simple.)

Then, the bid/ask is $10.00/$10.05 and the current price is $10.03. By placing a buy order at $10.20, the price will start trending upwards. So, if no-one comes along to trade in the next two minutes, the price will reach $10.05 and the order will fulfill since there are sellers at $10.05. This will clear the buys and the "pressure" on the price will return in to between the bid/ask spread.

On the other hand, if a seller comes along after a minute and places an ask at $9.90, the trade will complete at $10.04, and both traders benefit.

I'm not sure what the implications are but I'm not sure if you understood the time-varying, averaged price concept btilly was proposing.

In the CAT example, I would expect the price to have trended to between the Bid/Ask spread from the last trade price (say it's $22.00) So that's where the order can execute if buyer and seller arrive at the same time.

Again, I have no idea if this is good idea and the mechanics seem over complicated, but thought it was worth pointing out what might be a good idea.
Price will surely go down, but as long as they have exclusive control on supply, and the ability to manage it smartly they could still make a ridiculously huge amount of money.

Few things need addressing here:

- Google is the one that needs to survive Facebook. Not the other way around. Right now Facebook has the more compelling advertising platform that they are only starting to use (see: mobile). If companies do start moving money across it could do some immediate damage to Google's bottom line.

- Google Maps is going to have a rocky road ahead if Apple does plan to release iMaps for iOS 6. And given the talent Apple acquired it could be something special.

- Google+ will never be the default on iPhone. Twitter is. Facebook will be.

The problem for Google is that they have made enemies of Apple, Microsoft, Yahoo, Twitter and Facebook. Not a good situation to be in.
As long as they are charging more than their operational costs, they'll eventually turn a profit on any hardware investment.

Get a discount for buying in bulk, calculate your operational cost and failure rate, and go for volume. They have years to make their money back on this..every month their investment in new hardware gets closer and closer to being profitable.

Oh no don't get me wrong - the site is great and I expect it'd be very useful for any entrepreneur, whether seeking investment or not! I'm commenting on the GP's post, which implies some people aren't capable of answering questions this quickly because they have a different mental processing style.

The reality is they need to realise they're approaching people with little free time who have to quickly sort the wheat from the chaff, and asking basic, targeted business model questions like these are a fair way of doing so.

These types of questions aren't meant to make any sort of statement about the person's worth; they are there to determine (a) if the person, at this point in time, is investable as an entrepreneur at the most basic level, i.e. do they understand the basics of business, and have they done their homework with respect to their business; and (b) whether the results of that homework suggest a business potentially worth investing in.

A person with positive scores on both these accounts would be able to easily answer these questions in the time allocated. For the remainder, either they don't have a viable business model (fail at (b)), or they aren't familiar with business (fail at (a)), and that's why the site is valuable -- it gives the latter experience validating their business model before the pitch, which may otherwise cost them a missed investment opportunity.

(That being said I didn't like some questions: "Tell us something surprising you have done" or "What's the funniest thing that has happened to you." Have a few beers with me and all kinds of stories will come out, but I don't have a reverse lookup for my experiences -- my mind goes blank when I'm asked questions like these! That being said, it's good to be aware they might be asked, and to at least prepare in some way to respond.)
It appears you don't work at a large company. In large companies, even Google, there are loads of bureaucratic red tape and political bullshit that must be cut through to get anything company-changing done. It almost always takes the attention and support of the most senior level management to cut through this. If you need their attention you better hope they're not focused on something else at the moment.

I've made arcade side scroller with potentialy infinite world. Everything (terrain, objects, backgrounds) was created on the fly, basing on the coordinates of the player.

It wasn't really infinite, but only because coordinates would wrap at 32 bit, if you fly far enough into one direction (but I've never had the patience to test this).

It's linux only, and not very playable, but if you want to test it - it's here http://alan.umcs.lublin.pl/~ajuc/programy/gry/hw3/

It requires libraries SDL, SDL_image, SDL_ttf, SDL_mixer, paragui (version >= 1.1.8). Works with software rendering so no acceleration needed.

I've been quite satisifed with terrain generation - I've calculated noise value (a few octaves of 2d Perlin noise) for every tile on screen, tiles with noise values over bias were solid, others were empty. I hadn't checked if there's always way out, but after tuning amplitudes and frequencies of noise generator I've never had problems with that in game.

Then I've had look up table that returned tile depending on which neighborns are solid and which are not. To cut the number of tiles I needed to draw I've used hex-like layout - every second row of rectangular tiles were shifted half an tile to the right. Thanks to that every tile had only 6 neighbourns, instead of 8. So I've needed 128 instead of 512 tiles. And it made levels look more "organic", than with regular 2d grid.
I am not an expert, but my understanding is that it would have some effect (worse than UK hosting, presumably better than outside EU), but I doubt very much. Faster hosting should have a positive effect, too.

In Economics 100% opposed people can both get nobel prices. Somethimes two people that oppose each other get it together. Its a Social Sience you cant prove anything and its really really hard to make a conclusion for the real world. In Economics people talk about the same issues for hunderts of years, mostly the diffrents schools just develop there own theorys further.

That all said economics is a wunderful subject, it trains the mind in another was then for example programming does. Economics can help you understand things that would otherwise not be possible.

You, that app owner? That's easy enough to convince yourself you're doing "enough".

Whoever runs your app's hardware/network? That's harder - if you let other people have access to the hardware, you've lost the game. Traffic analysis on the network give a lot away too, even if you trust SSL sufficiently to secure the content of the communication.

The police? That's harder - what're you (or your colo/cloudprovidor/isp) gonna do if guys with guns show up at the door?

The "government" (choose whichever FBI/CIA/NSA/TLA)? Ummm, good luck with _that_.

I think the comments here have a lot of logical, well thought out ideas. The thing is, who cares whether they will ever be able to do it or what the implications would be if they succeeded? The fact that someone is seriously thinking about this type of thing is just awesome. Regardless of whether they succeed or fail, the most valuable output of this won't be the precious metals. It will be the technical innovations that would be created in order to attempt to achieve the goal.

It's sort of like how the value of going to the moon was not just the PR and historical significance, but all of the technical innovations like satellites that ultimately came from that effort.

I thought the SC2 missions were great and had a lot of variety. The missions were very original compared the usual you get from RTS campaigns.

On the other hand, and I can't explain why, the atmosphere of the SC1 was a lot better. I don't know if it's the music or the graphics but it really had a great feeling of "you are alone in space and everything is hostile".
After a certain amount of equipment has been launched, they will no longer have any need to get more stuff into space, as everything they need will already be there. All they have to do is make sure they can reach that tipping point where they can construct the bulk of their miners in space (Building the hulls out of asteroid metals, and then just launching the smaller, complex, electronic etc parts from earth).

Break even for these people wont come from the first asteroid they mine - and I doubt they are expecting it to.
> Having said that... must be at least a year since YouTube switched from 5-star ratings to positive/negative ratings. Maybe it's not totally relevant here, but I'm interested in what effect the switch has on ratings.

I think conceptually they are different. +/-, yes/no, thumbs up/down work best "would you recommend this?", just like "liking" or "+1"ing, or up-voting links on HN and reddit.

Star-ratings are still best for when you critique a more extensive piece of work, and may be accompanied with a review. "This book is good and I recommend it, but I think xyz is better and it lacks from these reasons, so it gets 3.5 stars."

Both are relevant and different ways of designing user-feedback, and certainly too often companies have mistakenly used 5-star rating when a binary recommendation is more appropriate.

Probably the best example is bulletin board/forum systems. They all seem to come with 5-star ratings for threads, but conceptually it makes no sense. You don't critique a conversation as "well this conversation is interesting, but not as good as this conversation, so i rate it 4 stars out of 5. OP: Next time i would recommend writing things more in this style for a certain 5-star thread next time!"

Here conceptually, you either recommend a thread ("check it out!") or vote it down ("this isn't worth your time clicking on"), a la links at reddit and answers on SO.

Most youtube videos are the same, as the vast majority are single-concept videos, be it music videos, comedy, sketches or otherwise, often just 2-3 minutes in length. Either you recommend it or you don't.

But multi-star ratings still makes sense in contexts where your review is multi-faceted. A hotel may be good for some reasons, bad for others. Longer experiences (say a vacation, extended experience with a business), and long-form media books, feature-length documentaries etc, are still appropriate for a star system.
heck why?

Very interesting idea.

I'm not sure about the goto though (despite/because of it being something I learned as a child).

When I used goto it was in the form goto linenumber, but if you're having to create explicit labels to jump to, it would seem easier (to me) to give those labels some explicit structure as loops or functions which doesn't need to be explained at first (they can just act like goto labels) but can be built on later.

e.g. the classic:

10 print "name"
20 goto 10

in this scheme becomes

label start
print "name"
goto start

so why not

loop
print name
restart loop

and then later the label loop could become loop while or loop until or loop with item from list. "restart" makes sense both at the end of a loop and if you wish to continue with the next iteration after a test. Using goto to break out of a loop could be exit loop or continue after loop.

I'm not sure what other uses of "goto" you'd expect at this level beyond restarting or exiting loops. If/then seems to take care of simple code branching until you get to procedures.

I think it would be difficult to avoid using any framework and build everything yourself, but I guess the question is more on what the balance should be. I have found that when starting out a project where you don't have any existing code, you typically need to rely a lot more on existing frameworks. Over time, however, you realize which parts of your application are commoditized vs your core area of focus. You still may use external frameworks for your core stuff, but I have often found myself rewriting and replacing framework-based components as you need more optimization and customization.
