    The Crystal Programming Language

    Project mention: Downsides (andUpsides) of ruby ? / tips for novice (w/Python) ? | reddit.com/r/ruby | 2021-09-11

    Here's where things get a little confusing. There are now languages which have the same syntax as Ruby or Python, but are compiled languages. Crystal has the same syntax as Ruby, but with a compiler that compiles down to native object code and optional Strong Typing (it's like Static Typing, but without the implicit type conversion). Nim has the syntax of Python, but with a compiler that can compile down to native object code and Static Typing. This means that when you need the performance and Type System of a compiled language (ex: performance is a key requirement, or you need to replace slow code in your project with faster code), you don't have to learn a completely different language from Ruby or Python. You can easily switch between Ruby and Crystal, or Python or Nim, and get the best of both worlds.

    Project mention: Making an mpd-based music hosting site. | reddit.com/r/webdev | 2021-08-27

    hey r/webdev, i have a side project i want to make, where users with different logins can upload music files onto a server via ftp, and listen to it back via mpd. I've decided for the meantime, on using the [amber framework](https://amberframework.org/). Each user will have a basic username/password login with *optional* OTP sent via email, a specific limit on the amount of storage they get (say, 5-10Gb), and a user-specific mpd connection\*
