Distribute your Go program (or any single binary) as a native macOS application
// Package main is a sample macOS-app-bundling program to demonstrate how to
// automate the process described in this tutorial:

// Bundling the .app is the first thing it does, and creating the DMG is the
// second. Making the DMG is optional, and is only done if you provide
// the template DMG file, which you have to create beforehand.

Ping less patch for MySQL.
# frozen_string_literal: true
# By default, ActiveRecord will issue a PING command to the database to check
# if it is active at various points. This overhead is unnecessary; we instead
# attempt to issue queries without checking the connection, then if the query
# returns an error and the connection was closed, try to reconnect.
# This also allows for reconnection during a single UoW, improving resiliency
# under transient connection failure (e.g. ProxySQL restarts).

# To avoid amplifying load when a database is intermittently down, the attempt

Use Honeycomb to trace ActiveRecord calls inside of ActiveJob
class ApplicationJob < ActiveJob::Base
around_perform do |job, block|
Honeycomb.start_span(name: job.class.name) do |span|
span.add_field 'type', 'worker'
span.add_field 'queue.name', job.queue_name
block.call
end

Getting Logitech F310 to work with Macbook USB-C port

Connect & use Logitech F310 with Macbook

Since my Macbook Pro only has USB-C port, I used an USB-A to USB-C adapter to connect my F310 to it, but it does not work (pressing MODE button does not turn on the LED).

How to

To make it work:

  • Disconnect F310 from Mac
  • On F310: switch X-input to D-input
  • Hold Logitech button (in the middle)
  • Connect F310 to Mac via adapter, now you can release the Logitech button.
