Out of interest, how far can buying and selling shares be made automatic? How far do you think it can go? And what would you need to do it?
Very far.
There are real computers performing fully automated trades as we type.
I'd take a look at some trading APIs provided by E*TRADE https://us.etrade.com/e/t/activetrading/api or something similar. You can use virtually any language to call the API and execute trades, get quotes, and generate strategic algorithms.
However, a fair warning, unless you are a large corporation with lots of money to burn you need to be careful as a homegrown algorithmic trading system can be very dangerous.
I believe something like 70% of all trades on the market today are placed by computer systems automatically and not by people. It makes it harder for smaller individuals to compete because we simply don't have the financial resources to purchase the power and speed we need to compete.
Thanks,
Jeffrey Pry

It is really simple question.
However, really wondering.
I think even we don't software testing,
Program will work.
So, What happens if we don't software testing?
When you are so sure about the your software, why not just wait and see what happens? The simple fact you are asking the question means that you suspect you overlook something, and yes, you are. Testing software is not only about working or not, but concerns the quality of the software, including usability, performance, security, compatibility and so on and what can be improved. Are you sure color-blind people can use your software and your application is free from security vulnerabilities?
The software might work, but you won't know1 it works.
However, history has shown that all software has bugs. Your software will be tested. The question is, do you want your customers to find the bugs, or do you want to find them before the customers do?
1 of course, even with testing you won't know with 100% certainty, but you will certainly know with more than 0% certainty. If you are writing a tic-tac-toe game, a low level of certainty is quite acceptable. If you are writing software for medical equipment, nuclear reactors, or airplanes, your level of certainty needs to be much higher.

I am in the process of evaluating whether BigQuery could be a good choice for some data processing we want to run periodically.
I do appreciate that BigQuery is still under heavy development and that improvements and fixes are likely to happen pretty often.
I woud like to know what would be the process should a release break a previously working process. I have read the SLAs, but they seem to be more oriented to downtime, rather than regression issues/bugs. Is there an option for paid support with SLAs?

I've been trying to describe the concept of platforms to some non-developer people on my team. I'm trying to explain how platforms are more than just tools and environments. For example, the Facebook Platform. How to describe the fact that the platform is more than just the website, but includes protocols like XFBML, opengraph, etc.
Facebook Platform is one example, but I would be interested if anyone has an abstracted way to describe what 'platforms' are in the tech world. I've had difficulty explaining this concept before in situations unrelated to flash.
Analogies that aren't tech related would be helpful as well.
I would say something about it being all-inclusive and extending to include all functionality that the entire ecosystem around that particular piece of software needs to thrive.
The Wikipedia page might help in putting it into words: http://en.wikipedia.org/wiki/Computer_platform
I use a "restaurant" metaphor, myself: Think of the kitchen, the bar, the dining room as components to the platform. How the decor can change in the dining room without changing the function, but can affect how customers perceive the business. How the recipes instruct the cooks, and the interactions with the wait staff can all affect different aspects of the business much like different pieces of your platform can be modified to affect different aspects of your business. Oh, and don't forget management!

I'm thinking about making some apps for phones. For the sake of this discussion say it's a generic Yet Another Zombie Shooter game, for Android, iPhone, Blackberry, or OVI Market. It is a kind of casual game that the customer would fire up while in boring class in school or waiting for a bus to come in. Let's also say that the game basically doesn't cost me anything to make, because I have a day job, and I make these apps in my free time.
The question is, how much to charge for this kind of app. I'd be perfectly happy with $0.99 price tag, but as I've read some articles about this on the 'net, they say that people see product's quality reflected in the price, so they'd consider $0.99 game inferior to $2.99 game. Something called a Perceived value pricing.
To summarize this, some profits would be nice, but I'm not aiming to rake what I can from the customers. But on the other side, I also don't want to release the software for free, a little extra money always come in handy.
P.S. I've read Joel's Camels and Rubber Duckies, but this is a different type of market.

I am very curious to find out how much money an e-commerce company is making.
Is there a way or ways to find this out (apart from techcrunch.com/) ?
Thanks
It is going to depend on if the company is public or private. Obviously with public companies, their earnings/profits are published each quarter. There are also many other metrics which show how well a public company is doing (ie. stocks, dividends). This information is available from a number of places. Private companies are a bit different, as they really don't need to tell you much. One can usually infer how well they are doing to a certain degree, however this has no guarantee of being accurate.
Disclaimer: I'm a developer, not an econ or business major :)
Not sure if this is a stackoverflow question but if they are publicly traded they have to submit forms to the sec and provide them to you upon request so you can go that route. If not then you might just be out of luck.
