For Chrome, at least, you're completely wrong. Chrome (or more specifically V8) maps all code pages as RWX, then starts writing and modifying code in-place in those RWX pages. Having writable code is required for several V8 features, like inline caches and code garbage collection. Chrome is just as bad in this regard as Safari. However, it's not allowed to do this on iOS, only on desktops and Android (AFAIK).

They have created a PHP-to-C++ translator called HPHP (or HipHop), years ago. The code that it generated wasn't really human-readable or maintainable.

Much poorer countries than the US have far fewer felons (in fact, the US has the highest incarceration rate in the world). Poverty isn't correlated with the number of felons. I think it's ignorant for a citizen of the world's top superpower (and one of the richest countries on the planet) to argue about desperation. I grew up in a developing country, with many more poor people and in worse situations than any I've heard about in the US, and yet they don't go around murdering others for food (except if they're criminals). By the time the US is in that bad a shape, much poorer countries will already be much worse off and probably invading.

Such as? If you're going to say "taxes", I'll object; taxes hit poor people the least.

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.
