Make /robots.txt aware of the Rails environment

You probably don't want Google crawling your development staging app. Here's how to fix that.

$ mv public/robots.txt config/robots.production.txt
$ cp config/robots.production.txt config/robots.development.txt

Now edit config/routes.rb to add a route for /robots.txt, and add the controller code.

class PolicyTest < ActiveSupport::TestCase
  def assert_permissions(current_user, record, available_actions, permissions_hash = {})
    permissions_hash.each do |action, should_be_permitted|
      if should_be_permitted
        assert_permit current_user, record, action
      else
        refute_permit current_user, record, action
      end
    end

Get ClamAV running on Mac OS X (using Homebrew)

The easiest way to get the ClamAV package is using Homebrew

$ brew install clamav

Before trying to start the clamd daemon, you'll need a copy of the ClamAV databases.

Inside /your/location/to/brew/etc/clamav, you'll see 2 files:

import pkg from "../../package.json";
import resolve from "rollup-plugin-node-resolve";
import babel from "rollup-plugin-babel";
import path from "path";

import { terser } from "rollup-plugin-terser";

process.env.BABEL_ENV = "production";
process.env.NODE_ENV = "production";

Learn Go in ~5mins

This is inspired by A half-hour to learn Rust and Zig in 30 minutes.

Basics

Your first Go program as a classical "Hello World" is pretty simple:

First we create a workspace for our project:

rpearce

:def hoogle \x -> return $ ":!hoogle --count=15 \"" ++ x ++ "\""
:def doc \x -> return $ ":!hoogle --info \"" ++ x ++ "\""
:set -Wall
:set -fno-warn-type-defaults -ferror-spans -freverse-errors -fprint-expanded-synonyms
:set prompt "\ESC[0;32m%s\n\ESC[m[ghci]\ESC[38;5;172mλ \ESC[m"
:set prompt-cont " \ESC[38;5;172m> \ESC[m"
