We used to joke "write once run away".

Why do you care when the object gets freed?

I have no industrial experience with phone software, so I can't speak to that. But the research surely delivered for software in the large. In the same way that compilers can no longer optimize code as well as virtual machines can, it's a bit conceited to think we could hand-code memory management of complex systems better than the computer itself.

Also, in addition to app performance, the second metric to consider is programmer productivity, and gc's impact there is incalculable.

If these things are important to you, then you are programming in an arena where Java is the wrong choice. These are not defects in Java's design, but Java is not the best language for, say, writing device drivers.

Part of it might be because the sales guy drank and partied his way through college while the science majors were suffering through actual hard work. There just might be some resentment that somebody who made no actual contribution to a technical product just got a huge commission off it.

I agree, and it would be a better policy to define acronyms the first time they are used. The same could be said about the names of software packages in other summaries. I'm mystified that so many commenters are miffed that GPU is explained.

That's an unfair comment. Acronyms can stand for more than one thing, and a good writer's intent is not to show how much smarter they are than their readers.

Social interaction is education. Did any undergraduates actually learn anything from their professors? The only things I remember learning, I learned from my peers.

Why does it bother you to work for someone younger than you?

This, this, a thousand times this.

It's nice that you can cite examples of casually dressed folks that have landed jobs, but why sabotage oneself? When an interviewee shows up without a suit it means (1) that they were too clueless to know that some interviewers would take that as a lack of respect, or (2) they knew it but felt that their skills were so awesome that they could deliberately do so anyway. Why hire the ignorant or the arrogant if there are alternatives?

Illegal or not, agedness is not "suspect class" in the U.S. if I recall correctly. This means that the burden of proof for age discrimination falls on the plaintiff, not on the company. Such lawsuits are therefore difficult for the prospective employee to win.

It's not? I sure don't feel like I'm moving.

How exactly do I observe them? Are you sure that's what you meant to type?

These are two very widely held beliefs, but they are false. The Copernican model of the solar system was not less complicated than Ptolemy's. It even had more epicycles, for example. It also never displaced the preeminence of the Ptolemaic model in the minds of many astronomers as you suggest. Basically, Ptolemy's model gave the right answers, so why abandon it?

Years later, Kepler's model was indeed simpler. But Copernicus was neither simpler nor more popular than Ptolemy. We remember him, though, because heliocentrism is essentially correct.

I agree. Their response was careless.
