Fixing Text Anti-aliasing in Fedora
  1. Add the RPMFusion repositories (both free and non-free) to the YUM repository directory (/etc/yum.repos.d/):
sudo dnf localinstall --nogpgcheck http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm
  1. Install the patched version of FreeType with subpixel rendering enabled:
sudo dnf install -y freetype-freeworld

An pair of Objective-C categories on NSArray and NSMutableArray that provides a mechanism for weak referencing any type of Objective-C object. This was created when I found a case, referencing protocols, where NSPointerArray did not work for my needs.

Ed25519-based semi-private keys

Semiprivate Keys

🚨 DANGER: INSECURE! 🚨

This may have seemed like a great idea in 2013, but the repeated "set/clear bits", a.k.a. clamping phases at each level of the hierarchy slowly subtract key strength.

Don't use this as described. Check out Ristretto.

Original text

Semi-private keys are an expansion of the traditional idea
