If you are working with SCSS/SASS, you might still wonder how to organize your CSS classes. The pre-SASS conventions like OOCSS seem not to be necessary in SCSS, since SCSS has mixins, placeholders and variables.

But there is one very powerful feature of SCSS, which we want to take advantage of now: inline sub selectors in selectors.

.b-post {
  .title {
    color: #f00;

    &:hover {
      color: #fff;
    }
  }

  &.is-new {
    background-color: #aaf;
  }
}

Today I tried to configure the sender for sendmail in php. There are some ways how to do it, so I share my solution.

There is a sendmail_from setting in php cli and php fpm, but it is usually empty. So sendmail fallsback to user@hostname (given you are logged in as user and the machine is called hostname).

But I found a better way (maybe even easier to extend). Just change the sendmail_path to something with an extra -f [email protected] at the end.

If you want to debug or enter your docker container, you might think that you will easily run a sshd server and that's fine. But it's wrong and most of all: it's not necessary.

Like @jpetazzo explained in "Docker SSHD considered evil": containers run with only one executable as main process. So if you want to have a sshd next to your php-fpm, you will need monit or supervisor to launch them. That's already 3 services in total!

That's why: keep your docker image clean!

But how to enter the container? There is a little tool called "nsenter" (available with util-linux >= 2.24)

If you are working on a new API for one of your projects, you might consider a media type like HAL or Collection+JSON as an option for structuring your API responses.

First of all, check out api-craft mailinglist or hal-discuss mailinglist for really good ontopic discussions about api architectures and media types.

Common JSON media types do not support a method parameter on relations

In HAL relations are defined in links, like this (e.g. self and http://example.org/rels/appointment/cancel):

{
     "_links": {
       "self": { "href": "/appointment/123" },
       "http://example.org/rels/appointment/cancel": { "href": "/appointment/123" }
     },
     "patient_id": "jsmith"
   }

Even though the relations for a patient appointment are available, it's not clear which http method to use.

I finally released a new major version of jsb.

With 2.0 there are two breaking changes (you might still use 1.x series, if you rely on those.

1. The global JsBehaviourToolkit got removed #20.
2. A input[hidden] cannot be used as data source anymore #17.

That's it.

But jsb 2.0 comes with some cool additions.
