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.

From what I can tell from online forums and posts, one of the main focuses of BDD/ATDD seems to be on discussion and ensuring that the customer, developers, testers and other relevant parties are involved in the understanding what the system must do.
Question 1: Do BDD/ATDD stories replace the need for traditional requirement specifications, such as the those captured using the Volere Template?
Because the traditional requirement specifications are one of the key inputs for developers and testers, traditional requirement specifications tend to be comprehensive.
Question 2: Should BDD/ATDD stories also be comprehensive enough to allow a system to be fully tested?
Question 1: Instead of looking at this question as a black-and-white situation, we should better understand how these two requirements capture methods get along with each other. Writing a story in the BDD/ATDD methodologies, or in Scrum for example, does not imply removing the templates like volere off the table. If we take a look at the volere requirements specification here, we can see that most of the information regards to project-related issues, and the shell used for functional requirements is far from being different to a story. They just have different information, not exclusive one.
Question 2: Here we have the advantage coming from the methodology itself. BDD comes from TDD, we can more or less rely on the test-first oriented process to allow the team to test the system. But, as I mentioned in question 1, making a BDD/ATDD story more comprehensive is not a sin, and wouldn't compromise the general idea of the story. This would also prove useful when interacting with more experienced clients.

My company has been using FogBugz for a while now and we are generally happy with it as a bug-tracking tool. I've been reading Joel Spolsky's articles about their Evidence Based Scheduling feature. It sounds great in theory, but I haven't seen much discussion about how well it actually works in practice. Before I spend a lot of time and effort trying to convince my co-workers to buy in to using it, I'd like to hear from people who have been using this feature in their development.
Have you been using FogBugz' EBS? If so, are you happy with it? Have its estimates been accurate enough to be helpful? With the benefit of hindsight, do you think it was worth the effort to set it up and input all of the information/estimates it requires? Is there some other mechanism that you found that works better?
(Note: I've deliberately posted this to stackoverflow.com rather than fogbugz.stackexchange.com, since I suspect that the user base at fogbugz.stackexchange.com might be unduly biased in favor of FogBugz -- in particular, ex-Fogbugz users who've moved on to something better are unlikely to read or post there)

For the last few years I've been working as a self-employed software developer. Doing various gigs as they came my way. For the most part I've been fairly lucky, as my own personal network has yielded all the work I need to sustain myself and then some. As I said, I've been lucky to get all my contracts, I haven't had to put any real effort into finding work yet.
Although I'm currently employed, I'm unhappy and thinking about moving on.
My question is for the experienced self-employed contractors, how did you find your contracts? Are recruiters/headhunters/agencies helpful? What is the best way to expand your professional network? Can the internet be useful?
Thanks for the tips
Craigslist, network with former co-workers. Stay away from rent-a-slave and elame sites. They will only waste your time and frustrate you (I want a youtube/facebook/amazon clone for under $500).
Local is better. Clients love to have you come onsite and talk with them.
It will take a bit but after a while, you will find enough clients who keep you busy and you won't have time to look for new ones :D.
Start off moonlighting so you can keep the lights on and the internet paid while this ramp up happens.
Good luck!

I've recently been looking at Extreme Programming and wondering if it would be realistic to implement it where I work.
My question is, if you're pitching to a potential new client and you tell them that you're using XP, and you explain what their responsibilities are as the customer, are they likely to be put off selecting your company if they've never worked within an XP environment before?
What are peoples experiences of selling XP to a client given that it seems to me to be a very customer intensive software development methodology? The context here is selling medium to large websites to a a wide variety of clients.
I usually try to explain it to my clients in non-technical terms, and focus on the benefits of my business model. With XP, you'll always have a higher degree of communication with your clients. This is always a plus for them. They like to know what's going on. Focus on that. Also, focus on the idea that they are able to discuss business requirements with you as the process moves along, so they don't get tied down into doing something the way they first envisioned it 6 months ago when they didn't really know what they wanted. This will also allow your contracts to extend their lifetimes when your clients get comfortable working with you and want to continue improving their products.
I'm working on a project that uses XP. The weekly meeting with our customer and the outcome of these meetings was that good, that our customer decided do try to implement an 'agile like' process as well.
Additionally I think that agile is getting more and more common in IT projects and that more customers are satisfied by the outcome of these projects. So I think that in a couple of years it will be harder to sell a non-agige project than an agile one.

Better appreciating just quite how dumb I really am.
Starting from the perspective of assuming that you're misunderstanding what's going on helps a lot.
Started answering questions here - the ability to explain complex things in a way other people can understand them is very useful.
Not to be a smart-arse. People don't like smart-arses.
If you think you are right and everyone else is sure you are wrong, just agree and continue being right. Trying to argue it out just results in a negative outcome when people are not open to persuasion or are being stubborn.
The best way to improve your soft skills is to use your soft skills. Put on a lunch time seminar for your fellow work mates. Nothing too scary, just pick a technology that you think could be introduced in house to make things work more efficiently, put together a five minute presentation and set some time aside for questions and discussion afterwards. You might even start a trend, one day a week a different person can talk about something that interests them.
It's a tie between volunteering as newsletter editor for a local artists' group, and joining a small local theatrical dance group.
A few years ago I attended a workshop about communication. And one thing that I learned there and I will never forget was: Try to understand why people act as they act, try to understand their motivation doing things as they do. That helped me a lot, especially in managing the management...
I took a teaching course and have been doing a lot of teaching.
Where I work currently has some material about improving one's Emotional Intelligence which is something that has been quite beneficial for me as it helps demystify some of how the world works.
In terms of not learning something, working on making small talk and being a bit more laid back has also improved my skills as not everyone wants every little thing analyzed to death and beyond.
