Ace editor adds syntax highlighting and auto-indenting for in-browser code editing, with a working brace setup for Ruby on Rails Webpacker and Webpack 2.

l= shows the current file and line in byebug or ruby-debug; where and backtrace print the debugger call stack.

SVG files often need manual size and markup cleanup when the build pipeline does not handle them. SVGOMG runs SVGO in the browser with live preview and easy export.

RubyMine can misclassify a Ruby file as plain text after a filename without extension was created first, leaving syntax highlighting disabled.

Custom data can be attached to ExceptionNotifier fail mails from foreground or background jobs; overridden sections settings may hide it unless data is included.

Make a section stretch past a centered container to the viewport edges without hacks like huge negative margins or clipping; ::before and ::after extend the clickable and colored area.

Katapult 0.5.0 adds deployment support for Opscomplete, template copying to target apps, and improved Webpack-based deployment.

Inactive Google API projects can be hard to identify when notification emails mention only a project number. The Console search and dashboard hide that number, so locating the right project requires checking settings.

Pseudo-element styles are hard to inspect directly, but getComputedStyle can read ::before and ::after values for testing and color checks.

Removing classes by exact name is easy; removing unknown classes by pattern needs class list filtering or a removeClass callback.

MySQL subquery filters in WHERE id IN (SELECT ...) can force repeated scans and hurt update performance; a JOIN or preloaded id list is faster.

Track the number of Angular 1.x watchers on a page while developing to spot performance issues early. Runs as a bookmarklet and logs the count to the browser console.

RubyMine 2024.3 includes Grazie Lite by default; German spell checking can be enabled in Natural Languages or added with Hunspell and a German dictionary.

Parallel test runs in Geordi can break terminal I/O during debugging; forcing one process or using vanilla cucumber avoids breakpoint issues.

Rails secrets and other configuration values can be read inside webpack bundles with rails-erb-loader, enabling environment-specific client-side settings without hardcoding them.

One-time bindings with :: remove resolved AngularJS watchers and reduce digest overhead when values stay unchanged after rendering.

Indentation-only changes can cause noisy conflicts during merges or cherry-picks; -Xignore-space-change lets Git disregard whitespace differences.

Ignore selected hidden fields when rejecting nested records with accepts_nested_attributes_for, so blank child records are not discarded unexpectedly.

Reduce Font Awesome icon font size by subsetting unused glyphs with fontmin-webpack, keeping low CPU usage and no JavaScript while avoiding oversized font downloads.

Managing multiple S3cmd configurations reduces the risk of sending uploads and deletions to the wrong Amazon S3 bucket. Use separate config files or a symlink to switch between environments.

GitHub-sourced gems installed through Bundler can evade gem list and gem uninstall, leaving manual cleanup under ~/.rbenv as the only removal path.

No built-in RSpec matcher checks whether a string contains terms in a specific order; a multiline regular expression is a common workaround, but readability and failures suffer.
