1. Clone your fork:

git clone [email protected]:YOUR-USERNAME/YOUR-FORKED-REPO.git

2. Add remote from original repository in your forked repository:

cd into/cloned/fork-repo
git remote add upstream git://github.com/ORIGINAL-DEV-USERNAME/REPO-YOU-FORKED-FROM.git
git fetch upstream

Deploying a subfolder to GitHub Pages

Sometimes you want to have a subdirectory on the master branch be the root directory of a repository’s gh-pages branch. This is useful for things like sites developed with Yeoman, or if you have a Jekyll site contained in the master branch alongside the rest of your code.

For the sake of this example, let’s pretend the subfolder containing your site is named dist.

Step 1

Remove the dist directory from the project’s .gitignore file (it’s ignored by default by Yeoman).

AngularJS Directive Attribute Binding Explanation

When using directives, you often need to pass parameters to the directive. This can be done in several ways. The first 3 can be used whether scope is true or false. This is still a WIP, so validate for yourself.

Raw Attribute Strings

<div my-directive="some string" another-param="another string"></div>

Docker - How to cleanup (unused) resources

Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...

delete volumes

// see: https://github.com/chadoe/docker-cleanup-volumes

$ docker volume rm $(docker volume ls -qf dangling=true)

$ docker volume ls -qf dangling=true | xargs -r docker volume rm

#["LÓGICA DE PROGRAMAÇÃO" É BOBAGEM, e explicarei porquê.]

Se preparem que o texto é longo.

Várias vezes chegam novatos aqui perguntando como começar, e a galera diz "estuda lógica primeiro, depois vai pra linguagem X". Vivo dizendo que é bobagem. Ontem, em particular, falei isso, e vieram várias pessoas por inbox me perguntar porquê (e uma pra me xingar, achando que falei por arrogância).

Pra facilitar, eu vou escrever uma boa explicação de porquê "lógica de programação" é furada, doa a quem doer, e postar na APDA e no fórum da EnergyLabs (para futuras referências, porque esse assunto vai voltar, ctz).
