And you can get a macbook air for around $900-$1300. That's all you really need, nothing fancy.
And if your app is meant to be mobile, you can get deep into mobile web development and even create a very native experience. That's what forecast.io did.
Also as you probably know, in startups it's more about proving a model than having a fancy piece of software. Think about what features are going to attract customers asap. Iteration is easier when you have customers giving you feedback.
IMO RoR is the fastest way to make those vital iterations. Once you're sitting on your $5 million in venture cash you can worry about architecture and scalability.
That is one of my main worries actually. I want to have a solid foundation and principles of how I should build something. Or is my thinking flawed?
Nearly all modern languages have developed as some response to C, and Python is also studied because it has a good reputation as a first language.
Software development is about coordinating work so that it produces a product that is reliable and also on time and under budget. This is the sort of thing you can learn, somewhat, by examining the code and work done in open source, but mostly you learn it by working in a (good) software development office. It's important, but not something that is easy to teach while you are also learning how computer languages work.
So for:
1. Some people told me I should start with C and go on from there, while others told me to start with C# or Python. Am I wasting time with C? I've seen some articles here where some guys went straight RoR and managed to get an app running in months. I feel like I would skip important stuff if I do that. How important is the order in which you learn these? I think this is the hardest thing for me. To choose which one goes first on the backend side I mean.
2. So it shouldn't be a problem to go for an old mac right? I don't have 2K right now for a maxed MBP.
3. Well I figured I can do it on a 10-15h a day marathon for 4-6 months. So I can't do a YC demo for example?Something to show to investors or enough to express an idea?
4. I believe I got this covered although everyone is pretty busy these days:)
