Font Combiner modifies TTF and OTF fonts by importing glyphs as vector shapes and regenerating them with alternate metrics, hinting, kerning, and spacing.

Rubygems version mismatches can break generated executables with undefined method activate_bin_path after downgrades. Reinstalling gem executables with gem pristine --all or reinstalling RubyGems and Bundler restores working binstubs.

Old net-ssh versions can fail to connect when servers disable weak ciphers; pinning net-ssh or updating SSH client support restores deployment access.

Rails 2.3 apps need a config.ru file for Passenger 5+; without it, nginx or Apache may return 403 errors because the app is not detected.

CSS breakpoints can be grouped by similar screen sizes instead of devices, keeping most screens between thresholds and reducing edge-case layouts.

/boot can fill up from old kernel images and initramfs files, blocking upgrades and updates. Removing unused kernels and shrinking initramfs frees space safely.

Gnome and MATE panels can steal focus in Awesome WM 3.5 when switching desktops. A window rule and an autofocus.lua replacement prevent the panel from taking focus.

External displays on a docking station may fail to activate or mirror the same layout; resetting them and reapplying xrandr settings can work around a kernel bug.

Dual-screen presentations on Linux can keep speaker notes or a projector preview visible without cloning displays. x11vnc and a VNC viewer provide a local preview of the second screen.

Upgrading to Bundler 1.13.x can break parallel_tests with a LoadError when loading Gherkin formatters. Setting bundle config --local disable_exec_load true restores the old behavior.

Command-line tests with Aruba can accidentally run real external executables; Aruba Doubles provides stubs for those binaries when PATH is adjusted with Aruba's official API.

Rake tasks appear in rake -T only when they have descriptions; removing comments or whitelisting tasks keeps internal tasks out of the task list.

Memoized ActiveRecord values can stay stale in specs even after reload; re-finding the record or clearing memoization avoids false failures.

Ruby module subclassing injects state and defines accessors when included, enabling trait-like macros and partial classes for cleaner model organization.

Haml mangles Angular 1 dynamic class attributes and can trigger [$parse:syntax] errors. Use ng-class or avoid Haml class interpolation.

Sidekiq monitoring needs a JSON status endpoint for queue sizes, worker activity, and recent failures. A cron-triggered heartbeat job and Redis timestamps let external checks detect stalled background processing.

AngularJS service kinds differ in configurability, injection style, and object shape; factories are usually the default choice, while providers support configuration and decorators extend existing services.

closure_tree adds hierarchical tree support to ActiveRecord models with efficient reads, pre-ordered trees, and safer concurrent updates than ancestry.

AngularJS -watch registrations can be removed after a condition is met, avoiding unnecessary change detection once a scoped value appears.
