Given that the machines have to have the acoustic networking software installed on them (requiring already having root access), this is at worst a covert communications channel that could be used to bypass network security controls in order to exfiltrate information from an otherwise secure network. It has no impact on whether machines can be hacked to begin with.

I don't know why people keep submitting this garbage from Espresso Logic, who is just taking advantage of the fact the the term "reactive" has been overloaded to mean different things to exploit the hype surrounding the Reactive Manifesto and related technologies (e.g., Akka, Rx, Node.js, etc.) to push their own, completely unrelated product, which is based on the more traditional (i.e., the one you find in Wikipedia) definition of "Reactive Programming".

"Reactive programming", as defined by the Reactive Manifesto (which is what all the hype is about), is about designing applications that operate in an entirely asynchronous and non-blocking manner, so as to maximize CPU utilization and fully exploit parallelism, and ensure that the system is always responsive to new events (user input, incoming data streams, errors, changes in load, etc.) rather than having resources tied up waiting for external processes (e.g., blocking on I/O). It has nothing to do with "reactive databases".

And what are they going to do for the remaining 6 hours of the night during winter?

Dammit! That should have read "had NO anti-tank capabilities".

Many early tanks (up through WW2) had anti-tank capabilities (indeed, the first tanks had no reason to have anti-tank capabilities - there were no other tanks to fight against). The main distinguishing features of a tank are its armor (which need not necessarily be very heavy - just enough to deflect small arms fire), its tracks, and the fact that it has some sort of weapon mounted on a turret.

The Panzer I was classified as a light tank but was armed only with MG13 machine guns. The British Vickers Light Tank Mk VI likewise only had .50cal and .303cal machine guns.

Rhino runs an interpreter that first compiles JavaScript into its own pseudo-bytecode, and then interprets the pseudo-bytecode. I believe what Oracle is proposing is to compile JavaScript directly into Java bytecode, using the new features of the JVM to handle the dynamic aspects that weren't possible with previous versions of the JVM.

document structure != layout

The header and footer are part of the structure of the document.

The fact that they appear at the top and bottom of the screen is part of the layout.

Only if they're targeting you by your DNS name and not your IP address.

Me too! I even still have Pidgin set up to log into it (along with every other account I have), though my ICQ contacts are so old I pretty much never talk to any of them.

Gadahi/Kadaffy/Qaddafi/whatever did say he declared a ceasefire. Meanwhile, Libyan tanks continued to roll into Benghazi to "disarm to protesters".

If the domain changes hands, that's going to break a lot of XML files containing xsi:schemaLocation attributes and DTD references pointing to documents within http://java.sun.com/xml/ns/j2ee/ .

You should just put a big banner across the top of the screen that reads: "BIG BROTHER IS WATCHING YOU." The government in 1984 gave full disclosure as well.

That said, they are your children, and by extension it's probably your computer as well (or at the very least, your Internet connection), so you're well within your rights to monitor how it is used. It isn't really even necessary to actually do any monitoring. As long as they believe they're being monitored, the effect should be the same.
