The problem:

So I had the issue that User input (coming from many different sources and users) often contains the same long word. Maybe that's a super german thing to have lots of long words I have to deal with. This long word needs to be fully visible on small screens but none of the automated word-break solutions offered by css (https://justmarkup.com/articles/2015-07-31-dealing-with-long-words-in-css/) is clever or supported enough to be a good solution. So I…

• Fixed #68: The "cucumber" command now fails early when @solo features fail.
• Added: The "setup" command now prints the db adapter when prompting db credentials.
• Fixed #71: When used without staged changes, the "commit" command will print a warning and create an empty commit. Any arguments to the command are forwarded to Git.
• Fixed: The "commit" command will not print the extra message any more.
• Added: The "commit" command prints a (progre…

You can use the Youtube API to get data from youtube. Here are some resources and some things that are good to know.

You need to create an API key and each request will cost a certain amount of Request-Points (depending on the kind of query).

It may help to understand youtube's domain model before starting.

It's best to just try out your requests in the browser to see what you will get.
A request can look like this (note that you have to replace the playlis…

There is a kind of features in web applications that hinder automated integration tests. Examples include cookie consent banners or form captchas. Clearly, these should be disabled so you do not have to explicitly deal with them in each and every test (like, every test starting with accepting the cookies notice). On the other hand, they must be tested as well.

A good feature disabling solution should therefore meet these requirements:

• The feature is generally disabled in tests. A test does not need to do anything manually.

• It is *…

Be careful when using buttons without a type attribute, since browsers will consider them the default submit button of a form.

Suppose you have this form:

<form action="/save">
  <input type="text" />
  <button onclick="alert('Alert!')">Alert</button>
  <button type="submit">Save</button>
</form>

If you press the enter key inside in the text input, browsers will trigger the first button and show the alert.

To fix this, add a type="button" attribute to the first button.

Coffeescript allows you to create classes whose methods are automatically bound to the correct this. You can do this by using a fat arrow:

class Person

  constructor: (name) ->
    @name = name

  sayHello: =>
    alert("Hello, I am #{@name}")

An important caveat is that when you clone such an object, all of its methods are still bound to the original instance:

eve = new Person("Eve")
eve.sayHello() # => "Hello, I am Eve"
bob = _.clone(eve)
bob.name = "Bob"
bob.sayHello() # => "Hello, I am Eve"

Rubygems supports a 2FA for your account. Once enabled you need to provide your personal OTP code for every release. Despite the CLI of the rake release task does not work well with the command promt for your OTP code with Bundler versions < 2.0.2. It just looks like the task is frozen:

• Workaround 1: Just type your OTP code and hit enter, your gem is released afterwards.
• Workaround 2: Upgrade to Bundler >= 2.0.2.. Your supported Ruby versions for this gem must be all >= 2.3.

JavaScripts and CSS should be minified for production use.

In Rails 3.1+ the asset pipeline will take care of this. Thus you're best off using an uncompressed version of your Javascript in development. Also load the non-minified versions of libraries. This way debugging will be easier and you will still get all the minification love once deployed.

In Rails 2.3 and 3.0 you should at least embed external JavaScript libraries in minified form, using something like JavaScript compressor.

Nowadays it is fairly easy to intercept and modify mails globally before they are sent. All you have to do is register an interceptor class which responds to .delivering_email(message). This card will show you two common use cases.

Subject prefix:

Usually you want to prefix the subject line of emails with the current environment (except production) so you can differentiate between production mails and mails from other environments. Of course a prefix can be set directly in the mailer, however, it is safer and cleaner to d…

This is a bookmarklet you can add to Chrome or Firefox which will allow you to create a story in Pivotal Tracker from a Zammad ticket. This might come in handy when creating stories for SWAT Teams.

But first you will have to set two variables in the script below:

• pt_project_id: the ID of the Pivotal Tracker Project you want to add stories to. This can be found as part of the URL of the project (https://www.pivotaltracker.com/n/projects/<pt_project_id>)
• pt_token: the Pivotal Tracker token used for authentication. Can be found in y…

When text renders differently in Firefox and Chrome, it may be caused by a font alias that both browsers handle differently.

Situation

A machine running Linux, and a website with the Bootstrap 3 default font-family: "Helvetica Neue", Helvetica, Arial, sans-serif.

Issue

Anti-aliasing and kerning of text looks bad in Firefox. Worse, it is rendered 1px lower than in Chrome (shifted down).

Reason

Firefox resolves "Helvetica" to an installed ["TeX Gyre Heros", which is its Ghostscript clone](https://www.fontsquirrel.com/fonts/…

The Ruby standard lib ships with a YAML Parser called Psych. But serializing and deserializing data seems not as obvious as if you are using JSON.

To safely write and read YAML files you should use Psych#dump (String#to_yaml) and Psych.safe_load (YAML.safe_load):

data = {'key' => 'value'}.to_yaml
=> "---\nkey: value\n"
YAML.safe_load(data)
=> {"key"=>"value"}

Unfortunately you might encounter a few pitfalls which are not obvious in the first place. All of them are a side effect that you can not configure Psych#dump to w…
