Updating Chromedriver is often a hassle: If you use chromium-chromedriver from the Ubuntu sources, it usually won't be updated when a new Chrome version is released. Manually downloading it from the official page is a very manual process. And I don't really want to use remote code like the "webdrives" gem because of paranoia.

Cry no more, for here is a tiny bash script that will download the latest chromedriver version and place it inside ~/bin. (If you use a different location, adjust accordingly).

```
#!/bin/bash

When using Chrome for Selenium tests, the chromedriver binary will be used to control Chrome. To debug problems that stem from Selenium's Chrome and/or Chromedriver, you might want to enable logging for the chromedriver itself. Here is how.

Option 1: Use Selenium::WebDriver::Service

In your test setup, you may already have something like Capybara::Selenium::Driver.new(@app, browser: :chrome, options: ...), especially when passing options like device emulation.

Similar to options, simply add an extra key service and pass an ins…

If you're suffering from a huge de.yml or similiar file, cry no more. Rails lets you freely organize your dictionary files in config/locales.

My organization works like this:

• config/locales/rails.de.yml modified Rails boilerplate
• config/locales/faker.de.yml modified Faker boilerplate
• config/locales/models.de.yml model names, attribute names, assignable_value labels
• `config/locales/views.de.y…

Whenever you create a table from a database migration, remember to add updated_at and created_at timestamps to that table. Without those timestamps, investigating future bug reports will be hell. Always have timestamps.

Adding timestamps to new tables

When you create a table using create_table, you can add timestamps by using the timestamps shortcut:

```
class CreateEpisode < ActiveRecord::Migration
def change
create_table :episodes do |t|
t.string :name
t.timestamps
…

Within an event handler, there are multiple methods to cancel event propagation, each with different semantics.

• event.preventDefault()

  Only prevents the default browser behavior for the click, i.e. going to a different url or submitting a form.

• event.stopPropagation()

  Only prevents the event from bubbling up the DOM. Note this effectively also cancels any event handlers attached through jQuery's live method, since those depend on bubbling.

• event.stopImmediatePropagation()

  Prevents the event from bubbling up the DOM…

This release makes it easier to migrate to a recent version of Unpoly when your app still depends on jQuery. Unpoly dropped its jQuery dependency with version 0.60.0, but retains optional jQuery support through functions like up.$compiler() and up.$on(). All Unpoly functions that take a native element as an argument may also be called with a jQuery collection as an argument.

The following changes to the optional jQuery support were implemented:

• In an ES6 build pipeline, …

The main benefit of our convention to prefix commits by their corresponding Pivotal Tracker ID is that we can easily detect commits that belong to the same story. You can either do that manually or use the bash script below by copying it somewhere to your .bashrc.

```bash
# Usage: ptcommits '#123456'
function ptcommits {
if test "$1"
then
git log –oneline | grep "$1" | grep "^[a-z0-9]*" -o | xargs –no-run-i…

When you have a string containing umlauts which don't behave as expected (are not matched with a regexp, can't be found with an SQL query, do not print correctly on LaTeX documents, etc), you may be encountering umlauts which are not actually umlaut characters.

They look, depending on the font, like their "real" umlaut counterpart:

• ä ↔ ä
• ö ↔ ö
• ü ↔ ü

However, they are not the same:

>> 'ä' == 'ä'
=> false
>> 'ä'.size
=> 1
>> 'ä'.size
=> 2

Looking at how those strings are constructed reveals what is going…

Spreewald comes with a selector_for helper that matches an English term like the user's profile into a CSS selector. This is useful for steps that refer to a particular section of the page, like the following:

Then I should see "Bruce" within the user's profile
                                 ^^^^^^^^^^^^^^^^^^

If you're too lazy to manually translate English to a CSS selector by adding a line to features/env/selectors.rb, we already have an [auto-mapper to translate English into …

When you want to group rails models of a logical context, namespaces are your friend. However, if you have a lot of classes in the same namespace it might be tedious to specify the table name for each class seperately:

class Accounting::Invoice < ApplicationRecord
  self.table_name = 'accounting_invoices'
  ...
end

class Accounting::Payment < ApplicationRecord
  self.table_name = 'accounting_payments'
  ...
end

A replacement for the self.table_name-assignment is the table_name_prefix in the module definition:

```
module Accou…

The ruby sass gem also installs a command line tool to convert to and from SCSS. Use it for a directory of .scss-files like

sass-convert -R assets/stylesheets --from scss --to sass

CSS transitions are a simple animation framework that is built right into browsers. No need for Javascript here. They're supported by all browsers.

Basic usage

Transitions are used to animate the path between to property values. For example, to let the text color fade from red to green on hover, the following SASS is used (shorthand syntax):

.element
  color: red
  transition: color .1s
  
  &:hover
    color: green

This tells the browser "whenever the color of an .element changes…
