Using Xdebug in Docker

Getting setup and running with Xdebug in a docker container these days is now fairly simple and is composed of two main steps:

Ensure you've got XDebug installed and enabled in your PHP docker image, for example:

# Installing Xdebug with PHP 7.3 images:
RUN pecl install xdebug \
  && docker-php-ext-enable xdebug

doChunks()

Very simple but useful PHP function for performing work on large arrays of information. Basically, it's like pagination for callbacks. For example, this can be used for performing bulk database INSERT operations (instead of inserting each item individually). See below for a quick real world example.

Example Usage

Full Screen Bookmark / Bookmarklet

Can't go to full screen easily? On a website and hate their customized version of a video player and just wish you could use the one built into your device or browser? It turns out there's a solution: In many cases, you can actually bypass this by simply taking the <video> element on the page and forcing it to go to full screen immediately with a single press using a simple bookmark (or, a bookmarklet to be precise).

Instructions

Create a bookmark, call it Full screen and copy/paste the following into the URL field:

javascript:(function()%7Bvar fsvs %3D document.getElementsByTagName('video')%3Bfor(i%3D0%3B i < fsvs.length%3B i%2B%2B) %7Bvar vid %3D fsvs%5Bi%5D%3Bwindow.fsv %3D window.fsv %7C%7C vid%3Bvar playing %3D !!(vid.currentTime > 0 %26%26 !vid.paused %26%26 !vid.ended %26%26 vid.readyState > 2)%3Bif (playing) %7Bwindow.fsv %3D vid%3Bbreak%3B%7D%7Dif (window.fsv) window.fsv.webkitEnterFullscreen()%7D)()

Unshittify Reddit Images

This reverts the shitty wrapper that Reddit forces on you when you try to view images on their website. This is done via a bookmarklet (see URL below).

Create a new bookmark, copy/paste this code into it and then whenever you visit an i.redd.it image link and get redirected, this will fix the page so that it's just the image. Saving you from the varous bugs/issues induced by their platform (such as the header or footer overlapping the image itself when you attempt to zoom in on the image).

javascript:(function()%7B(()%3D%3E%7Bconst%20t%3Dnew%20URL(location.href).searchParams.get(%22url%22)%3Bif(!t)return%3Bconst%20e%3Dnew%20Image%3Bfunction%20i(t)%7Bvoid%200%3D%3D%3Dt%26%26(t%3D%22initial%22!%3D%3De.style.maxWidth)%2Ce.style.maxWidth%3Dt%3F%22initial%22%3A%22100%25%22%7De.setAttribute(%22src%22%2Ct)%2Ce.addEventListener(%22click%22%2C(()%3D%3Ei()))%2Ci(!0)%2Cdocument.body.innerHTML%3D%22%22%2Cdocument.body.appendChild(e)%7D)()%3

`kubectl-sure`: Provide confirmation when in sensitive contexts

This bash function provides an extra failsafe that may help prevent you from accidentally running kubectl commands in the wrong context (or in contexts which could cause issues, such as shared or even production clusters).

Demo

Running kubectl in prod on accident:

	<?php
	/**
	* Helper functions to cleanly alter versioned objects in SilverStripe.
	*
	* Usage:
	*
	* whileDraft(function() {
	* $page = Page::get()->byId(123);
	* // ... with great power comes great responsibility...
	* });

	# .bash_profile

	# Get the aliases and functions
	if [ -f ~/.bashrc ]; then
	. ~/.bashrc
	fi

	# Launches ssh-pageant.exe (instead of ssh-agent) to connect to PuTTY's pageant.exe, an SSH key management process for Windows.
	if [ -x /usr/bin/ssh-pageant ]; then
	eval $(/usr/bin/ssh-pageant -r -a "/tmp/.ssh-pageant-$USERNAME")
