As a very young programmer looking to make some money along his studies in the UK, I want to know where I can find clients, or even start a portfolio that's more than a few open source projects on GitHub.
I posted an offer to HN to build their app for £100. Monetary value is obviously very little, but it's a token gesture that technically gives you freelance experience.
It was great to build my portfolio up; I'd recommend it if possible. It's much easier to land gigs with a freelance portfolio.
I find them really hard to follow. Threaded commenting isn't so fun when you can't collapse a single comment's thread. Instead, if I want to know who is being replied to, I need to place my finger on the screen and scroll up, seeing on who's comment it lands. That tells me which comment the current one is replying to.
4chan (well, imagboards in general) have a nice system where you can reply to multiple people at once by referring to the post id. Top-level comments are usually represented by referring to no comment, or by referring to the OP's post id. I find this much, much easier to follow.
I actually quite like Mac OS X. Things seem to "just work" most of the time, or at least, more of the time than they work for me on GNU/Linux. I can't give any examples off the top of my head, but it seems everything in OS X just "flows together" much nicer, and that's even including programs like Chromium which aren't from Apple.
The reason why I don't use it, however, is because it's tied to the hardware in such a way that if I want this "just works" feeling, I'd need to purchase hardware from Apple, which for me seems overpriced and it shouldn't be necessary. Further, OS X has its quirks that don't let you run it like Linux or BSD - for example, installing things like PostgreSQL.
