What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

Setting up a Raspberry Pi 2 Samba server (in early January 2016)

The following is how I configured a Raspberry Pi 2 as a samba server, using a Seagate Backup Plus Slim, 1TB, drive.

For ease I purchased the CanaKit Raspberry Pi 2 Complete Starter Kit. It runs about $70 and includes enough to get up and running with the Raspberry Pi 2, with the Pi itself, a nice case, power supply, HDMI cable, WiFi adapter, and SD card with NOOBS/Raspbian installer.

For the hard drive I opted to purchase a Seagate Backup Plus Slim 1TB Portable External Hard Drive, since I've had good enough luck with Seagate in the past, and reviews are generally favorable.

Unfortunately, once I received the Pi and drive I found that the power supply/Pi wasn't putting off enough power to keep the drive running. After looking at the options, including tweaking the Pi to pass throu

PostgreSQL

Creating a postgresql 9.5 container with persistent database

docker volume create pgdata
docker run --detach \
  --volume pgdata:/var/lib/postgresql/data \
  --name postgres \
 --env POSTGRES_PASSWORD=postgres \

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

	Combining characters[edit]

	In plain text scenarios where markup cannot be used, Unicode offers a number of
	combining characters that achieve similar effects.

	The “combining long stroke overlay” (U+0336) results in an unbroken stroke
	across the text:

	if [ -z "$1" ];then
	echo "Usage:"
	echo " proj2ram proj-name"
	echo " proj2ram restore proj-name"
	exit 1
