Log Management: What is the complexity behind Loggly and similar services?

Pricing isn’t about how hard it is to build something (and building a reliable, highly-scalable centralized log search and archiving system isn’t trivial). It’s about how much value it provides to the customer.

Is greater comfort with Windows a good enough reason to switch from PHP to ASP.NET?

Learning Linux really isn’t that hard, and it will dramatically increase your potential horizons as a programmer. Install Ubuntu on a virtual machine on your laptop and start running through some tutorials.

Is there a substantial difference between using a Mac or a Windows machine for web development (particularly RoR)?

No matter if you are on Mac or Windows you should be using a Linux virtual machine for development, ideally running the same operating system as you deployment environment (I like Ubuntu for this). Vagrant is a popular tool for managing this kind of setup.

As a non-technical single founder for a web startup, is it better to hire a design firm to build the prototype, or find a technical co-founder?

Find a co-founder. The problem with using an outside agency to build your initial prototype is that you won’t really start learning about your product until after you have launched it. You need to have the talent available in-house to then make changes and improvements based on the feedback you get from real users.

Would YCombinator have invested in Apple?

Yes. YC is about the team, and the fact that those two had built a prototype of a personal computer in their garage (in 1976!) would get them in to YC without any trouble, even considering the quality of applicants YC gets today.

YC want founders who are going to dedicate themselves full time to their companies after the initial three month YC programme has ended. If you’re not willing to do that, why should YC give a place to you over someone else who IS willing to make that commitment?

When did South Park characters stop calling things “gay” in the vernacular derogatory sense “not very good”?

There was actually an episode that touched on a similar issue back in 2009: http://en.m.wikipedia.org/wiki/T...—“the boys attempt to change the official definition of the word ”fag“ from an anti-homosexual slur to a term describing loud and obnoxious Harley bikers.”

Is it fair for someone who calls themselves a “seed” investor to require traction?

It’s completely fair. If you’re building a web-based startup these days, you should be able to demonstrate initial traction on an idea with very little up-front investment—a couple of months of your time and a few hundred dollars in hosting costs, perhaps. Being able to do that is an excellent indicator that you’re a good bet for a seed investor. If you are unable to do that, you’re a much higher risk for investment.

What is currently the best technology stack for web scraping?

PhantomJS combined with CasperJS is pretty fantastic—it runs a full, headless copy of a Webkit browser so it can operate against a real DOM, execute JavaScript properly, even grab full rendered screenshots of areas of the page but is still easy to automate.
