Bundler 1.1 can trigger a misleading Cucumber warning during test runs; disabling automatic loading for cucumber-rails removes it without moving the gem into a test group.

Plain-text task lists stay portable across devices and apps, with Dropbox sync, mobile editing, and a CLI for quick task management; nesting is not supported.

validates_acceptance_of silently skips nil attributes, so a missing checkbox or typo can leave acceptance unchecked; a boolean field with validates_presence_of is safer.

New branches pushed to origin do not track a remote branch by default, so git pull cannot follow their upstream; git push -u sets the tracking reference immediately.

Constrain a Rails route to a single response format such as XML when one URL must serve only that representation.

\G in the MySQL shell switches query output to a vertical format, which is easier to read for wide rows or long text fields.

Use Tab and Shift+Tab in regular textareas to indent or outdent code for in-browser editing of HTML, CSS, JavaScript, or server-side languages.

Find the most frequent string in an array without failing on empty input; the approach uses grouping and returns the first value from the largest group.

JavaScript key binding library for handling single keys and key combinations in web apps.

Filter MySQL connections to hide idle sessions and focus on active or slow queries, with flexible sorting and column selection via information_schema.processlist.

Temporary monkey patch for older Capybara and selenium-webdriver versions to suppress repeated deprecation warnings from Selenium::WebDriver::Element#select.

VirtualBox NAT guests can reach the host at 10.0.2.2; vbox.srv is the matching hostname for shared folders and host web server access.

Capybara's save_and_open_page files can clutter the Rails root when debugging Cucumber scenarios. Set Capybara.save_and_open_page_path to store them elsewhere.

Connecting Ruby applications to SQL Server through ODBC can unblock legacy setups when native adapters fail. sequel can use an existing ODBC DSN for database access.

RubyODBC fails to create an ODBC environment handle when connecting Ruby 1.8.7 on Ubuntu 10.10 to SQL Server 2005; rebuilding the gem with the correct unixODBC path restores connectivity.

Automatically unlocking and mounting a second encrypted HDD at boot avoids repeated password prompts by using a keyfile, cryptsetup, and mount.

MySQL sessions can default to ASCII, turning accented text into question marks or garbled output. SET NAMES 'utf8'; enables UTF-8 in the console.

Markdown in single-line form fields can create unwanted block elements and broken display. Restricting formatting to inline text keeps input and output consistent.

A profile of _why and his influence on Ruby and Ruby on Rails, with a personal angle that makes programming culture approachable for nontechnical readers.

Capybara text checks can match a <textarea> instead of rendered page text; filtering to visible static content avoids false positives.

rails console fails with no such file to load -- readline when Ruby was built without readline support. Reinstalling Ruby with the readline development library available restores console input.

Bundler 1.1 speeds up dependency installation by fetching required metadata in seconds instead of waiting on source index updates.

typhoeus native extension builds fail when libcurl headers are missing; installing the libcurl3-dev package resolves the gem installation error.
