Ask HN: Where to learn about real-time collaborative systems

I am interested in learning about real-time collaborative web applications: how they are designed, what problems need to be addressed, etc. I have tried looking around but find it hard to get the information I am looking for.Can someone point me to some resources that I could read further?

Ask HN: What smartphone to get right now?

I am currently on an AT&T family plan in the US. I currently do not have a smartphone, and it is annoying because as a tech person, I feel like I am falling behind the curve. However, I have been hearing all kinds of disappointments with new phones lately, so I ask: if you were to buy a phone today, which would you buy? Or would it be worth waiting for a little while to see how other phones...

Ask HN: How do you focus your studies?

I think many of you out there are like me in that I am a super curious person. I love to learn about how things work and why they are so. Specifically, many areas of computer science greatly interest me. The downside to this is that I end up spending equal time on many different areas and am left being "decent" at a couple things but not "great" at anything, which makes me feel like I don't...

Ask HN: How do I get involved in open source projects?

I want to get involved in an open source project, but am not sure the best way to do it.I figured I would just get on github, look for an interesting project, and would start working on it.But it turns out, most of the projects I have found on github are just a single guy or a small group and they do not have a list of bugs anywhere for me to try to fix. Also, I don't know enough about the...

Ask HN: The Right Now Company vs The Innovative Future

I am sometimes told by successful entrepreneurs that to be super successful, you need to have a vision for the future, and to spend your time morphing the current world into that vision, small steps at a time.But then I see a lot of successful startups that seem to just build things that somebody has a need to pay for to solve some problem today. The company does not at least appear to be born...

good point, but what happens when you get stuck and can't think of something to work on that people care about? Obviously, a person who loves to learn won't take it as a moment to veg out, but may instead focus on problems that stretch the mind to generate some new ways to think about problems.

But there are lots of problems that stretch the mind. Perhaps you choose to spend your time learning about modern computer architectures. If this interests you, great. But from a startup perspective, it probably has a lower expected chance of spinning out a startup for you than say working on an information retrieval system.

But perhaps it is better worth your time just talking to people about their problems. I'm sure there are success stories on both sides of the spectrum.

I was a bit unclear, but what I mean is that can I live a life where I build things and get paid for it as opposed to spending time writing research papers and attending conferences, which I am under the impression requires getting a PhD to be taken seriously.

As far as where to work, anything from a startup to a large corporate company could potentially fit the bill.

Ask HN: Machine learning careers

I am interested in machine learning and natural language processing, but am slightly put off from devoting a significant amount of time towards it because I am under the impression that to make a career doing this, it is seemingly mandatory to have a PhD and you will be working in a research lab at a large corporation, the government, or a university. Is this true?

Ask HN: When did you get good at computer science?

I am currently an undergraduate senior majoring in computer science. My last few years, I have been learning computer science through a very breadth first approach, always working on different types of projects or reading about something different every couple of days. Although I have learned a lot, I feel like I am not amazing at any one area of computer science.I thought by this time in my...
