Simon Robert's philosophy in training is "understanding is greater than knowledge" meaning simply that although learning facts might be helpful, they can often be looked up. By contrast, it's understanding that allows us to make effective use of those facts, and to extrapolate to new puzzles....

This makes it possible to create systems that “self heal”, meaning that if an actor gets to an exceptional state and crashes, by whatever reason, a supervisor can do something about it to try to put it in a consistent state again (and there are multiple strategies to do that, the mos...
Current Behavior The build using v8.9 has a FAILURE. FAILURE: Build failed with an exception. What went wrong: Could not determine the dependencies of task ':connector-api:compileJava'. Could not resolve all dependencies for configuratio...
such optimizations do not affect the meaning of sequential programs, but the situation is different for concurrent programs as different threads may have subtly different (inconsistent) views of the shared memory and thus their execution may result in an unexpected (non-sequentially consistent) behaviou...
If your task is I/O bound, meaning that the thread spends most of its time handling I/O such as performing network requests. It is still perfectly fine to use multi-threading as the thread is, most of the time, being blocked and put into blocked queue by the OS. Thread is also alwa...
Suppose that at some point in the program the dictionary becomes fixed, meaning no more insertions or deletions will be performed on it. Once all threads know this point has been reached (probably by reading some other synchronized shared-memory object to make sure that all threads are finished...
Retrieval operations are nonblocking for performance reasons, meaning they can overlap with multiple concurrent updates. This means retrievals only reflect the results of the most recently completed update operations at the time the retrieval is executed. ...
