Yay, deployed: https://github.com/cuducos/cunhajacaiu
It's a tiny project that I use to test my Elm skills and, surely, to learn Elm. Nothing very complex, Elm is updating the stopwatch, and loading the news — loading both initial data from different JSON API (but once loaded, no interaction is done but the “tick” from the stopwatch). Except exercises and tutorials, this is my very first Elm project, so probably there is a lot to improve (suggestions, comments, critiques, etc are more than welcome). The Elm modules are in cunhajacaiu/static/elm <https://github.com/cuducos/cunhajacaiu/tree/master/cunhajacaiu/static/elm> Many thanks for all the help, guys, Eduardo Cuducos http://cuducos.me/ On Tue, Jul 26, 2016 at 1:47 PM, Peter Damoc <pda...@gmail.com> wrote: > To paraphrase Satchmo, "If lots more of us helped each other, we’d solve > lots more problems.
