TCP: can two different sockets share a port?
...Most kernels (incl. linux) doesn't allow you a second bind() to an already allocated port. It weren't a really big patch to make this allowed.
Conceptionally, we should differentiate between socket and port. Sockets are bidirectional communication endpoints, i.e. "things" where we can send and rece...
Conditional Variable vs Semaphore
... Semaphores are good for producer/consumer situations where producers are allocating resources and consumers are consuming them.
Think about if you had a soda vending machine. There's only one soda machine and it's a shared resource. You have one thread that's a vendor (producer) who is responsi...
When is it better to use String.Format vs string concatenation?
...ring via ToString(). Then the total length is computed and only one string allocated (with the total length). Finally, each string is copied into the resulting string via wstrcpy in some unsafe piece of code.
Reasons String.Concat is way faster? Well, we can all have a look what String.Format is do...

You need to change the constructor to accept multiple input and then change the line: "boolean endsWith = fileEndsWith != null ? filename.toLowerCase().endsWith(fileEndsWith) : true;" to properly...

What is the difference between `sorted(list)` vs `list.sort()`?
... that you busted a myth too quickly. The fact remains that sorted() has to allocate a new list object and copy the references; the rest of the code paths are identical. See if you can run the same tests with larger lists. Compare it with just creating copies of lists and see if you can replicate the...
