Or, 16 cool things you may not have known your stylesheets could do. I'd rather have kept it to a nice round number like 10, but they just kept coming. Sorry.
I've been using SCSS/SASS for most of my styling work since 2009, and I'm a huge fan of Compass (by the great @chriseppstein). It really helped many of us through the darkest cross-browser crap. Even though browsers are increasingly playing nice with CSS, another problem has become very topical: managing the complexity in stylesheets as our in-browser apps get larger and larger. SCSS is an indispensable tool for dealing with this.
This isn't an introduction to the language by a long shot; many things probably won't make sense unless you have some SCSS under your belt already. That said, if you're not yet comfy with the basics, check out the aweso
Algum tempo atrás eu publiquei um artigo que ensinava como desempacotar aplicativos da Google Play para auxiliar no aprendizado através de engenharia reversa. No artigo eu busquei deixar claro que o objetivo era fazer com que "mais pessoas sejam capazes de otimizar seus aplicativos através das descobertas proporcionadas pela técnica".
E muita gente entendeu isso, mas ainda assim rolou bastante polêmica. Muita gente acredita que esse tipo de conhecimento não pode ser propagado. Talvez por medo ou algo do tipo. A questão é que eu acredito que só através do conhecimento nós seremos capazes de melhorar nossos aplicativos. Inclusive a engenharia reversa pode nos ajudar em diversas áreas, como segurança, performance, tooling, usabilidade, etc.
Enfim, eu poderia me estender mais, falando das questões éticas e morais do tema, mas já fiz isso no meu artigo anterior então vamos ao que interessa.
É importante ressaltar que para realizar os passos a seguir é necessário possuir um Mac e um d
