Then murder is definitely not justified (or even theft). Like it or not, you're competing against that group for money/resources, so you have to beat them in reasonable and legal ways.

The Russian Revolution was a disaster, and brought about a century of poverty, crime and suffering (in Russia and a lot of Eastern Europe). Also, the revolutionaries killed not just the "rich oppressors", but also a lot of people they just didn't like: intellectuals, artists, scientists, small business owners and so on (including some of their own). Personally, I'm fine with preventing something like that from happening again, but not by giving into their demands.

To me, the only valid provocation for violence is preceding violence (the only justified violence is self-defense). Someone not giving you their money is not "provocation" in my book. The difference between justifying and predicting it is simple: if it's just a prediction, then you also accept measures to prevent it (any measures, such as everyone arming themselves against these thieves).

That is a horrible and seriously criminal attitude. You're arguing that if others don't give you something you need, it's fine to just murder them (your words, not mine). Unprovoked violence is never justified; whatever your problems might be, you have to solve them peacefully (unless you get attacked first). This kind of Robin Hood-style violence does not belong in a civilized, developed society.

How does this "true communism" you speak of differ from the one that's been tried, and has failed over and over and over?

That's what people have been saying for the last 50 years or more, and I don't think we're any closer now than we were back then.

It's not effectively free, you just pay for it later through higher taxes (schools cost money to operate, and that money has to come from somewhere).

In the case of the US, a legal mechanism already exists to force foreign students to return to their countries. If a student studies in the US on a J1 visa, he/she cannot get another visa from certain categories (like J1 and H1B) or a green card for 2 years after the J1 expires. There's a way to get an exemption from this, but it requires that the student's own government signs off on it.

That actually exists, it's the J1 visa. It has a 2-year period where you can't get another US visa (from certain categories, like J1 and H1B), and the only way to get an exemption is with approval from your own country.

What would those "traditional means" be?

That actually exists, it's called an investment-based visa (code EB-5) and it takes $500k to get (by investing that money in businesses in certain areas). Most foreigners don't have $500k though.

WoW uses Lua, which is actually known for having a very simple and easy to use interface with C code. I even found an example on the Wikipedia page: http://en.wikipedia.org/wiki/Lua_(programming_language)#C_API

The original x86 had 4 ring levels and segmentation, and at the time we got AMD64 no one was using them (or at least Windows/Linux/*BSD weren't using them). AMD removed security measures because they weren't popular.

So? I don't get your point. Are programmers from outside the Bay Area prevented from applying to work at companies like Google/Facebook? Quite the opposite. However, if you're looking for a guy to write your next database engine/compiler/OS kernel/Internet-scale search engine, you will hit a shortage.

They do fit in, but there's a huge distinction and there are different levels of "IT worker". Not everyone has the same skills or gets paid the same. In some categories there is a real shortage. For example, most "IT workers" can use a database engine (like Oracle or MySQL), but very very few of them could also write that database engine efficiently (how many sysadmins know what a B+ tree is?)
