For no reason other than to play with Java streams, I am wondering how I could simplify the following code any further. It was using an iterator previously and figured I would migrate it to using Java streams. Am I doing this right? I am sure there are a vast number of ways to rewrite this code b...
I'm very new to Ruby and having a bit of difficulty with this project where I wish to create a journal a user can input into, have the input stored in an array, and allow the user to recall the entries by number or searching a certain term.

Writing game engine as a hobby, I've come across many situations where I need a container like a map, but searchable by different keys: a block allocator where a block needs to be searched by either offset or size, or resources searchable by either name or file.

Welcome to Stack Overflow! To get useful help, take a look at the asking guide. In particular, please try to make your question as specific as possible. Also, if there are specific critiques you would like, Code Review might be a better place to ask. (As a first suggestion for how to improve it, you could format it to be easier to read. Indent in multiples of 4 spaces and don't add blank lines except in between functions and to make the code easier to read.) — jirassimok57 secs ago
I'm voting to close this question as off-topic because it is about improving working code and therefore belongs on Code Review instead, which was created specifically for that purpose. — Ken White52 secs ago
I wrote a simple function that converts an array of words into proper case (using bit shifting) and returns the array. I performed a simple test using std::chrono to check how fast it was able to perform the conversion. Using a vector of 1000 words the function was able to do it in an average of ...

I would like to write a C++ code for the n-queens problem using the permutation approach. This means I index the queens from 1 to n, and the state of the checkerboard will be defined by an array where the i-th entry stores the row of the queen at the i-th column.
Clearly, such array will contain ...

You have to set ENV["RAILS_ROOT"] so that it points to the dummy application. Also nesting all your code inside a GEM_CODE directory is really questionable if you want to pass a code review. — max59 secs ago

IMO a song has no business knowing about any playlists, but that isn't something that can be objectively settled without knowing what your specific requirements are. Does your model work for your requirements? Looks like it's too early to ask for a peer review, since there's no code doing anything with any of these classes... I'd recommend getting your code to solve the problems it needs to solve, and presenting that code for review - the code is the design, and if it's wrong, reviewers will point it out - but we can't review a design. — Mathieu Guindon ♦1 hour ago
I haven't written a linked list from scratch in a couple years, so I decided to take a stab at it again. After working on it on and off for a little over a week, I'm finally happy with it.
