Conventional Commits

The Conventional Commits specification is a lightweight convention on top of commit messages. It provides an easy set of rules for creating an explicit commit history; which makes it easier to write automated tools on top of. This convention dovetails with SemVer, by describing the features, fixes, and breaking changes made in commit messages.

Os 10 melhores solos de rock

Na hora do café me deparei com a notícias do Jornal DestakRio sobre os melhores 10 solos de guitarra do rock. Eles diziam que havia saído a lista da Guitar World e que eles sentiam desejo de fazer as 10 deles também, pois viam que alguns ficaram de fora.

É interessante notar que as duas listas são muito boas e prova porque os autores dos solos são reverenciados como gênios. Há os mais gênios do que outros, mas isso é outra história. Só lamento meus guitarristas favoristos ficarem de fora (Edu Ardanuy e Yngwie Malmsteen). Fui bem apresentado a novos solos.

Certamente estas listas serão confrontadas, então, apresente a sua lista no comentário!
