title: Online C project for excercising?
body: <p>Recently I'm back into (embedded) C programming because of a new job.</p>
  
  <p>I never had a vast amount of C experience in my career and in the recent years (lacking in C) even that little amount dropped a little further. Thats too bad.</p>
  
  <p>So, in order to improve my C skills and to speed up my learning process I thought I could make some extra C excercises at home. First I wanted to find some kind of "excercise book" online that would be fun to solve. (This also might be a solution.) But then this came to my mind: isn't out there somewhere a project which is</p>
  
  <ul>
  <li>online</li>
  <li>organized and supervised/controlled</li>
  <li>under version control, possibly git</li>
  <li>open and recommendable to individuals even on unprofessional C level?</li>
  </ul>
  
  <p>I imagine myself here as some kind of volunteer who, while contributing to the project, would also learn a lot from it.</p>
