Core Data

• -com.apple.CoreData.SQLDebug 1-3 - print all SQL queries called by Core Data
  • -com.apple.CoreData.Logging.stderr 1-3 - needed alongside with the SQLDebug from iOS 10+ because of new logging system, more on that in changelog
• -com.apple.CoreData.SyntaxtColoredLogging YES - probably syntax colored logging (not tried)
• -com.apple.CoreData.SQLiteDebugSynchronous 1 - preference controls some aspects of the SQLite store. See the "Configuring a SQLite Store's Save Behavior" section of the Core Data Programming Guide for details
• -com.apple.CoreData.SQLiteIntegrityCheck 1 - the SQLite store does extra integrity checking
• -com.apple.CoreData.MigrationDebug 1 - Core Data will log information about exceptional cases as it migrates data
• -com.apple.CoreData.ThreadingDebug - preference enables assertions to enforce Core Data's multi-threading policy. It is a number, where incre

Methods of Signing Git Commits on MacOS

Last updated March 13, 2024

This Gist explains how to sign commits using gpg in a step-by-step fashion. Previously, krypt.co was heavily mentioned, but I've only recently learned they were acquired by Akamai and no longer update their previous free products. Those mentions have been removed.

Additionally, 1Password now supports signing Git commits with SSH keys and makes it pretty easy-plus you can easily configure Git Tower to use it for both signing and ssh.

For using a GUI-based GIT tool such as Tower or Github Desktop, follow the steps here for signing your commits with GPG.

wget --recursive --page-requisites --adjust-extension --span-hosts --convert-links --restrict-file-names=windows --domains yoursite.com --no-parent yoursite.com

# Explained
wget \
     --recursive \ # Download the whole site.
     --page-requisites \ # Get all assets/elements (CSS/JS/images).
     --adjust-extension \ # Save files with .html on the end.
     --span-hosts \ # Include necessary assets from offsite as well.
     --convert-links \ # Update links to still work in the static version.

libdispatch efficiency tips

The libdispatch is one of the most misused API due to the way it was presented to us when it was introduced and for many years after that, and due to the confusing documentation and API. This page is a compilation of important things to know if you're going to use this library. Many references are available at the end of this document pointing to comments from Apple's very own libdispatch maintainer (Pierre Habouzit).

My take-aways are:

• You should create very few, long-lived, well-defined queues. These queues should be seen as execution contexts in your program (gui, background work, ...) that benefit from executing in parallel. An important thing to note is that if these queues are all active at once, you will get as many threads running. In most apps, you probably do not need to create more than 3 or 4 queues.

• Go serial first, and as you find performance bottle necks, measure why, and if concurrency helps, apply with care, always validating under system pressure. Reuse
