Importance of exportable food is, idiot. US is one of the biggest exporters of food. Almonds bring discussed here are mostly exported.

No, you don't seem to understand my logic at all. Or economics, for that matter.

No. Farmers sell their produce to "city dwellers". Once sold, produce (food) belongs to the city dwellers and their eating it and producing wealth doesn't contribute to farmers' contribution to GDP at all.

Farmers are free to raise the price of their produce and hence increase their contribution to GDP.

Also, many good file systems are in Linux kernel tree, and many others can be compiled in. Windows kernel has poor choice of file systems.

A ringing phone can be ignored, silenced, numbers blacklisted. An employee who chose to not do any of these can reply to a text message/email as well. So no, this lack of confirmation is not the problem with text/email. Problem is expressiveness - human beings are mostly much more expressive in the spoken word rather than quickly written text, especially in rare complex emergencies. Human employees are typically paid for on-call access to mainly troubleshoot rare complex emergencies.

In any case, text message and emails are convenient to schedule a quick ad-hoc voice call on phone. So voice and text are not only not mutually exclusive but highly complementary.

Read your post I replied to -http://slashdot.org/comments.pl?sid=7166981&cid=49367041

YOU are now using a strawman by making "here the pilot ..." the topic; because there is no relevance of "here" in the context in which I was replying.

No it can't. He just has to pretend the levers/knobs are jammed. Touch interface is difficult to spoof.

If the pilot wants to damage the plane intentionally and make it look like it was not intentional, they could act as if airplane controls are not working, act surprised at it and keep acting as if trying to save the plane.

Camera never records intentions.

Beating inflation doesn't cause inflation.

No, it is not only not that simple, but it is plain wrong. Productivity improvements using, say, technology, can help a vast majority of people beat inflation, sometimes even everyone.

For someone to get market beating returns, someone else mustn't. But don't conflate market beating with inflation.

You do not know enough to conclude this.

How often do suicidal bus drivers drive off a cliff? Suicidal operators of huge industrial machines take down their workplace? Pretty rare, even if there are hundreds of times as many bus drivers / heavy machine operators as compared to airline pilots.

Many countries have zero effective regulation on bus driver / machine operators sleep cycles. Lots of drivers / operators work without any social interaction which could have helped detect and even prevent suicidal tendencies. This pilot was at least working along with another human being. Was in Europe - which at least on paper had good sleep cycle regulations, and knowing Europe, regulations would have had some force of effect too.

There could have been other reasons for this event. Your ignorance of them do not make those reasons stop existing.

Where there is a perhaps, there is no judgement.

But except saying it "dramatically" improves results, the StringBuilder result wasn't worthy of a mention or a compare against disk performance.

Obviously, like any good "researcher" does, the conclusion was written first and then the "experiment" was performed. Any results contradicting the conclusion have to excluded.

But it was never necessary for the "in memory operation" (their words) to use an immutable data structure. If you use bad data structure when using in-memory, of course in-memory will be slower than disk.

This "researcher" is an idiot. The java code given at the bottom of the "research paper" uses + operator to concatenate strings. This is O(N) in Oracle java. Total algorithm becomes O(N*N) in memory, and O(N) on disk.

Obviously N*N takes longer than N after a certain N even when N*N is running on faster memory.
