I am trying to make a Business Requirements Document and a separate Software Requirements Specifications document. From the following requirements statement, can anyone help me dissect business requirements from software requirements?
Design a system that will maintain positions in real time based on a feed of transactions – buys and sells – that come to the application via MQ. You should include initial positions loads, fault tolerance and error checking and handling for the process.
Thanks
What is the business process for maintaining positions? When does the business need a position? What triggers the need? What steps/tasks maintain a position? When is a position no longer required? Get answers to these questions and you will have business requirements.

I need to write the backend for an event ticket selling system. Some companies would connect to the service in order to check for ticket availability in certain venues, book tickets and so on.
Reading about Erlang I though it could be a good choice since the system will have to support high concurrency, high availability but I don't know If it's a good choice for this problem domain.
Any help would be really appreciated. Thanks!
Erlang could be a good choice, yes, it sounds like something it would do a very good job.
But it's going to be hard for anyone here to be of much value for your decision, as you should also consider the knowledge level of the team, time & budget constraints, etc.
Ultimately, the best people to help you make this decision are the people in your team.
I suggest you take a look at OTP's finite state machines as I think it suits perfectly a ticket booking system.
I believe you can find a lot of examples either in the doc or on the web.

Ive been trying to find an answer to what I thought would be a basic question.
What software development methodologies are relevant for a single programmer.
The only one I can find is RAD.
When I've looked into others such as agile they require a team of people.
Could someone more clued up point me in the right direction.
I am just looking for any methodologies that a single programmer can do so I don't waste more hours trying to find the answers.
Development methodologies like agile can be applied in almost any context, including going "solo". You just have to take the best out of it and apply it to your needs.
For instance as a single programmer you can have a product backlog with your user stories, you can give them story points, plan your sprints, find your velocity, etc.
In the end you'll be more organized and you'll improve your planning skills for sure.
Hey, i'm not saying that you must have daily standup meetings with yourself! :)
This applies to all development methodologies/processes(RAD, DDD, TDD, ...) don't forget they're just ways of doing things.

So I'm going to do an app. It will have about 100 recipes, and so far I've only done 4. I need to have it submitted to the App Store tomorrow.
My question is, if I'm not done by then, could I get away with just polishing what I have and then submitting it? Would Apple or my customers hate my client?
It is very rare in software development to release an application without a few known defects, so long as those defects are not critical to the functionality of the application itself. This is why versioned releases exist. That being said, unless you have a clear understanding of what your client wants, via a customer statement, it may be hard to determine whether or not your client will respond in a positive manner.
If you're down to a crunch, polish up what you've got, make sure it works, and cross your fingers. Your other option would be to request pushing back the release date.
4 out of a 100 probably wont cut it though. :P

I'm developing web-application (and also native iOS app) that uses images from different websites. I can't avoid using these images, so I need to know more about copyright and authorship.
So, the question is: how can I use images from other websites legally? (these images, of course, not from photostocks or other paid-sites). Interested in fashion industry, I need to use images of clothes of famous designers. If I would declare source link to each pic, will it be ok? Or may be use "User Agreement" that tells full list of used sources?
For better understanding my question, some examples: websites - news aggregators, blogs and so on.
This is a topic that books have been written about, and law school courses taught about. It's not something you're going to find a definitive answer for here.

I am curious if there are any common patterns for partitioning a web application by features? An example would be to sell at multiple price tiers.
What I am asking is there a common development pattern to partition features within an application
There isn't a pattern that I know of. One way of implementing what you want would be to give users roles dependant upon what price tier they have chosen and to then have role checking on specific features/views. Almost like a form of access control list, which is controlled by their purchased package.
