You’ve fallen victim to the most vexing parse, which means thisisanumber is being treated as a function. Take out the parentheses and you should be fine: Also consider making it a bit more readable, such as thisIsANumber. If you ever need to know it, thisIsANumber uses the camel-case naming convention.
This is entirely implementation specific, but it appears that in the C++ environment you’re working in, RAND_MAX is equal to INT_MAX. Because of this, RAND_MAX + 1 exhibits undefined (overflow) behavior, and becomes INT_MIN. While your initial statement was dividing (random # between 0 and INT_MAX)/(INT_MAX) and generating a value 0 <= r < 1, … Read more

Edit If you arrive to this question of stack overflow because you receive this message from docker, but you don’t use jenkins, most probably the error is the same: your unprivileged user does not belong to the docker group.

I hit the same error. I suspect you’re using Node.js 12 and Gulp.js 3. That combination does not work: Gulp.js 3 is broken on Node.js 12 #2324 A previous workaround from Jan. does not work either: After update to Node.js 11.0.0 running Gulp.js exits with ‘ReferenceError: internalBinding is not defined’ #2246 Solution: Either upgrade to … Read more
What does it mean, when a CPU usage of a core is 100 percent? Does it mean that a process has peaked the maximum possible performance of a core (with vectorization) or does it mean that the CPU is doing as many cycles as the core clock is? Also, if it is 100 percent, can … Read more
What can cause a java.lang.StackOverflowError? The stack printout that I get is not very deep at all (only 5 methods).
