Among the solvers some of the matrix solvers use FORTRAN and some blas. Again they too prefer C++ for most of the solution and reserve FORTRAN only for really serious loops.
But a question for those who have: Does it still win with dynamic memory allocation? How granular is the dynamic memory allocation? Complete like C? or it is a bastardized version where the common block sizes could be defined at run time and then it runs without ever calling free()? I could imagine the language getting malloc() but not free() to retain speed.
Technically it would be very difficult to stop an executable to run another executable in a sand box. Depending on how well you have understood the executable, you could do many things like step through debugging, poking and pushing memory etc. Debuggers work by "instrumenting" the executables, but they too act as man in the middle.
In this case Android executables are java which started out as an interpreted platform independent language. So it is a lot more "debuggable" than your typical linux or windows executable. So WhatsApp+ could theoretically sniff the memory locations and intercept communications, eavesdrop on the data and sell them to advertizers. One of the biggest thing about WhatsApp is, it does not eavesdrop, it does not sell ads. User are dumb to use this app.
WhatsApp itself should come out with a free version that would sniff the communications and sell ads and call it WhatsApp Minus. Or WhatsApp Minus Privacy.
Or a pet door or a cut-out door in the garage door. Works same way, can be locked without a key, but needs a key to open.
Far less complex, as reliable, and added bonus: The body you have hidden in the freezer in the garage would not be accidentally discovered by the deliveryman. (Note to self. Should cut down on watching Investigation Discovery shows.)
Long back Google had a April Fool posting about toilet net. That idea is fundamentally sound. The municipality can run fiber optic cables in storm water drains. It won't cost as much as it is costing Verizon to dig up and bury the cable. But you won't get it. They have the state law makers in their pockets.

But teenagers are susceptible, emotional and are vulnerable to cyber bullying. What possible solutions are there? When there is a complaint of cyberbullying, for America based social networks like Twitter and Facebook, the schools may be able to go through court order and make them disclose the origin of these bullying postings and tweets. So if there is a law against cyberbullying they may be able to trace the IMEI number, cell phone number, IP addresses and other things for social media sites within American jurisdiction. That might give probably cause to make FB and Twitter disclose more info, like all tweets from that IMEI number etc. That may help them catch the bully.
But if the provider is out of the jurisdiction of the American Courts, there is no way to get this info. But teens being teens, the bullies would be careless, use their cell phones and use most popular american providers. But this will lead to the same selection process that created antibiotic resistant bacteria. The casual bullies will be out, but the real careful, malicious, thoughtful and methodical ones, the ones that are really dangerous will migrate to anonymous servers and difficult to trace providers, congregate there and do more damage.

It will not be as easy as breaking up the travel agents business using the net by buying the ITA software or something like that.
