The problem

I've frequently been bit by failures restarting my vpn on my Mac. The connection may appear to start up in Shimo (the menu icon will change) but it looks like vpnc can't connect.

Looking at the log, we see the connection gets stuck

ERROR: can't send packet: Can't assign requested address

This has plagued me for a while, and my only fix has been to restart the machine. I hate restarting my machine. So I finally made time to dig in and find a better solution

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

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.
