samtsai / setup_launch_agents.sh
Created March 26, 2014 17:39
Setup launch agents (useful for automating brew installs and their startup script)
# Set Up Launch Agent to Run On Startup
function set_launch_agent() {
# retrieve the dependency's prefix
DEP_PREFIX=$(brew --prefix ${1})
# make the user local LaunchAgents directory (skip if already exists)
mkdir -p ~/Library/LaunchAgents
# copy brew generated plist to LaunchAgent
cp $DEP_PREFIX/*${1}*.plist ~/Library/LaunchAgents/
# load the agent now
launchctl load -w ~/Library/LaunchAgents/*${1}*.plist

samtsai / cy-all.ts
Created April 18, 2022 18:22
Typed `cy.all([...])` command for Cypress consumers
// @see https://github.com/cypress-io/cypress/issues/915#issuecomment-475862672
// Modified due to changes to `cy.queue` https://github.com/cypress-io/cypress/pull/17448
// Note: this DOES NOT run Promises in parallel like `Promise.all` due to the nature
// of Cypress promise-like objects and command queue. This only makes it convenient to use the same
// API but runs the commands sequentially.
declare namespace Cypress {
type ChainableValue<T> = T extends Cypress.Chainable<infer V> ? V : T

samtsai / normalize analytic strings
Created May 7, 2013 15:32
quick normalize functions for grooming strings passed into an analytics library like SiteCatalyst
// this would be set in a closure
// but leave some values to be cached (ie not created every function call)
// and the ability to override
var norm_regex = /\s+/g;
var norm_replace = "_";
function normalize( val, reg_pattern, separator ) {
// convert to string
var norm_val = val+"";
norm_regex = reg_pattern || norm_regex;

The true cause of frontend SPOF is loading a script, stylesheet, or font file in a blocking manner.
