Ask HN: What do you code when learning a new language/framework

• Exercism - website

  192 373 9.8 Ruby

  The codebase for Exercism's website. (by exercism)

  

  I use https://exercism.org/ with new languages to get a grasp on syntax and see examples that other people have submitted.

  It's far from a true comprehension of the language, but it is really helpful to tackle problems that I've already done a few times in languages I am more familiar with to help relate concepts and highlight the differences.

• hpHack

  1 3 10.0 C#

  collection of old scripts to hack display of hp Printers

  I always like to port L0pht’s hphack.c as my first project.

  It’s quick but it covers string handling including some weird stuff, sockets, and networking pretty well.

  Realtime retrospective tool built in ASP.NET Core and Blazor

  To learn Blazor and CQRS I coded two interactive planning poker and retrospective applications in Blazor - right at the beginning of the pandemic so that came right on time when working from home. I installed them at my work and we're still using them:

  For practicing low level code and sometimes exploring APIs like drawing graphics, I like doing https://adventofcode.com/; I mean I say I like doing them but I haven't touched them in a while lmao.

  But yeah, 'hacker' exercises are a great way to get acquainted with low level code.

  "The mother of all demo apps" — Exemplary fullstack Medium.com clone powered by React, Angular, Node, Django, and many more

  

  This is the approach I've settled on too.

  I'm almost finished my first backend implementation of https://github.com/gothinkster/realworld and now that I've implemented it once I'm very familiar with it and could very quickly implement it again.

  It's simple enough to be a short project, but with enough complexity to get you familiar with a wide variety of things you might care to know. One thing I like about it is you can kind of under or over engineer it as much as you want as a way to turn the dial either up or down on exactly how many different aspects of development in a certain language/framework it exposes you to.
