The problem with services like Airalo is that they almost never give you a local phone number. In many countries getting a phone number involves showing a physical id.
140k is believable, but I think they mean it's per person. If you rent, it's very unlikely you'd be able to buy a 1.2M house on 140k if you started with 0 in savings.
EDIT: To clarify my previous post - I was talking about the household income.
The definition of the middle class would surely depend on the cost of living in the particular area. You can make $30k and live like royalty in the 99% of the world.
Not in SV. $400k gets you to the lower middle class. That is you probably have a tiny chance of buying some real estate in your lifetime. House and expenses related to maintaining it is a huge chunk of change.
No, compressed oops mode doesn't change at runtime. That's pretty hard to pull off. You'd need to change object layout dynamically and unless you want to reformat the whole heap you'd need tags or regions with different pointer rules. Any of these techniques would have a very substantial runtime overhead.
AOT implementation in the JDK, that we call the "HotSpot AOT" implements tiered compilation (look for $JAVA_HOME/bin/jaotc). It is also based on Graal, but with a different set of plugins. You get reasonably good startup and re-JITing afterwards. Of course it doesn't give you compactness on the SVM, but it supports regular java code with class loading, reflection, etc.
You're missing the point that there is a positive feedback loop at the source of the problem. The reason that women (or minorities for that matter) don't get into some fields of STEM is because there are no role models that tell them it's a good idea to do so. So there is a chicken and egg problem, and the only way do break the cycle is to give priority to such minorities. Is it fair to the members of the majority? Perhaps not. But in the end, I believe, it will justify the investment. Consider it a small price to pay for the millennia of oppression.
Being passionate and dare I say obsessive about you work is good. I fact, it's the only way to achieve good results. That's what separates hackers from people that just go to work.
I didn't realize this until recently. Rude awakening. Even the most close relationships turn out to be quite transactional.
