... also fs.access(path, fs.F_OK, ...) / fs.accessSync(path, fs.F_OK). And at least as of October 2016, the fs.stat documentation recommends using fs.access to do existence checks ("To check if a file exists without manipulating it afterwards, fs.access() is recommended."). But note that the access not...

...hat you are passing is an rvalue. In itself, moving an object is still at least as expensive as passing by reference. However, in many cases a function will internally copy an object anyway — i.e. it will take ownership of the argument.2 In these situations we have the following (simplified) tra...

...tain "foo". It is not possible to reverse the hash as such (in theory, at least). The hash of "foo" and the hash of "saltfoo" have nothing in common. Changing even one bit in the input of a cryptographic hash function should completely change the output. This means you cannot build a rainbow table ...

This book is an extended version of the material that constitutes Chapters 2-5 of The C++ Programming Language, 4th edition. Accelerated C++ (Andrew Koenig and Barbara Moo, 1st Edition - Au...

...ut I'd like to point out some of the caveats of using static libraries, at least on Windows: Singletons: If something needs to be global/static and unique, be very careful about putting it in a static library. If multiple DLLs are linked against that static library they will each get their own co...

...rder to manage considering all consumers would need to read the message at least once, so one is better off with SNS combined with SQS for this use case, where SNS would push notifications to N SQS queues and every queue would have one subscriber, only) to process these messages. As of Jun 28, 2018,...

...dition. If you have, then check that when calling the function you have at least modified one of the arguments, otherwise there'll be no visible change for the recursively called function and the terminating condition is useless. Also mind that your stack space can run out of memory before reaching ...

... saying that private methods are implementation details which don't (or at least shouldn't) matter so long as the public interface is well-tested and working. That's absolutely correct if your only purpose for testing is to guarantee that the public interface works. Personally, my primary use for ...

...cally, about 5 of the pages will be empty. The other 245 will each have at least one allocated block in them. That amounts to 980KB of memory, that cannot possibly be reclaimed by the operating system - even though you now only have 100KB allocated! On the other hand, you can now malloc() 9000 more...

Creating the package itself is already covered by other answers here, so let us assume we have that step covered and our project structure...
