Last active February 5, 2024 05:03
A Ruby example of prepending a proxy module to a class to intercept method calls.
module MethodBroadcaster
def broadcast_calls_to(*method_names)
proxy = Module.new
method_names.each do |method_name|
proxy.define_method(method_name) do |*args, **kwargs, &block|
arg_strings = args.map(&:inspect)
kwarg_strings = kwargs.map{|k, v| "#{k}: #{v.inspect}" }
all_arg_strings = arg_strings + kwarg_strings
puts "#{method_name}(#{all_arg_strings.join(', ')})"
super(*args, **kwargs, &block)

Last active October 16, 2022 06:07
Markdown conversion of a planning outline for my Head First Go book. It may be instructive to note there are substantial differences between this and the content of the final book.

Syntax basics

  • Compiled language

  • Who created Go, and why

    • Fast builds
    • Fast execution
    • Concurrency
    • Garbage collection

Notes bookmarklet: Paste this into your browser's address bar (the separate lines will merge), then bookmark the resulting "page". You'll have a page with just a single, large textarea (which will have cursor focus). Just start typing whatever you want.

Due to the ubiquitous problem of tab overload, I need a way to remind myself what a browser window is for. I tried labelling tab groups in Chrome, but that gives me almost no space to work with. I thought I was going to have to install (and trust) an extension. So I was pleased to find a hack at the top of https://www.makeuseof.com/tag/use-browser-notepad/ I customized it a bit though.

Paste this into your browser's address bar (the separate lines will merge), then bookmark the resulting "page".

You'll have a page with just a single, large textarea (which will have cursor focus). Just start typing whatever you want.

It'll all disappear when you close the tab, which for my use case is a feature, not a bug.
