Quotes About Runtime

dynamically linked files, which can be plugged together at runtime, are the software components of our architectures.

I think Smalltalk is inappropriate for serious industrial developments. After all, run time is a little late to find out whether you have a landing gear.

My basic rule is, if it could possibly come from the end user, it's not a run-time crash. But if it is my code to my code, I crash it as hard as possible—fail as early as possible.

By lexical scope we mean that JavaScript's rules for scoping are based purely on the structure of your code (not on some dynamic runtime properties). This means you can determine where a variable is defined by simply examining your code's structure. Also

Sun's role in the grand scheme of development is to work on the runtime environment and the APIs. The tools we produce are much more for systems programmers, not enterprise developers.

A type system can be regarded as calculating a kind of static approximation to the run-time behaviours of the terms in a program.

When a field is declared volatile, the compiler and runtime are put on notice that this variable is shared and that operations on it should not be reordered with other memory operations. Volatile variables are not cached in registers or in caches where they are hidden from other processors, so a read of a volatile variable always returns the most recent write by any thread.

The possibility of incorrect results in the presence of unlucky timing is so important in concurrent programming that it has a name: a race condition. A race condition occurs when the correctness of a computation depends on the relative timing or interleaving of multiple threads by the runtime; in other words, when getting the right answer relies on lucky timing.

What is Node.js?

A class is thread-safe if it behaves correctly when accessed from multiple threads, regardless of the scheduling or interleaving of the execution of those threads by the runtime environment, and with no additional synchronization or other coordination on the part of the calling code.

A race condition occurs when the correctness of a computation depends on the relative timing or interleaving of multiple threads by the runtime; in other words, when getting the right answer relies on lucky timing.

Dynamic typing is not necessarily good. You get static errors at run time, which you really should be able to catch at compile time.
