Google wants to get rid of frustrating 404 error pages and make websites still feel interactive even if you're not connected to the internet. So, the company has recently developed a new technology called "Service Workers," and Google software engineer Alex Russell talked about it at length during the O'Reilly Velocity conference in New York this week. To be precise, Service Workers is a new browser standard that will allow websites to store documents locally (similar to apps), in order to render cached pages or any other interactive content anywhere you are. Say, you're loading a website just as you enter a tunnel or reach an area with no coverage, you'll then see an older version of the site instead of getting an error message. As Russell puts it, "We want to load something instead of nothing."
