Over the past two years, Facebook’s cooperation with browser vendors Google Chrome and Mozilla Firefox has dramatically improved web page reload speeds, according to the company.
Working closely with the browsers to squash bugs in the browser caching technique — temporary storage for files downloaded to your computer or mobile device, including html files, CSS style sheets, images, JavaScript scripts, and other media content — Facebook reduced its page reload times on Chrome by 28 percent.
As Google’s senior software engineer Takashi Toyoshima notes in his blog post, page validation requests between browsers and web servers can cause serious performance issues on mobile devices, such as battery drain.
At the onset of its research, Facebook found that Chrome was sending page validation requests at three times the rate of other browsers. Although this process didn’t result in any additional data being transferred to the user’s device, it was deemed a futile technique that was bogging down page refresh times. Once Chrome simplified its reload behavior to only validate the main resource on a page, it resulted in 60 percent less validation requests.
“Every time a user logged in to Facebook the [Chrome] browser ignored its cache and revalidated all the previously downloaded resources,” said Facebook Code team members Ben Maurer and Nate Schloss in a blog post.
Referring to the broader impact of the change on websites, Toyoshima said: “We hope this faster reload will come in handy whenever you want to get the latest content on your favorite website or quickly recover from a flaky connection in the subway.”
Testing out the change on mobile with a 3G connection, the Chrome team found that the reload rate was 1.6 seconds faster across all websites.
Similarly, Firefox implemented a cache-control feature on the most recent version of its browser on the back of a Facebook proposal. The change saw a reload generate just 25 network requests from a Facebook page, which can typically contain around 150 different resources. According to Patrick McManus, principal engineer at Mozilla Firefox, the change cut page reloading times in half.
McManus adds that other developers are adopting the feature, too, with the BBC revealing that page refresh times have improved by 50 percent. Facebook claims that the research conducted with Chrome and Firefox “highlights how web browsers can, and do, work with web developers to make the web better for everyone.”
After five years with Apple silicon, from the original M1 MacBook Air to the M5 MacBook Air released earlier this year, I've watched these chips mature not just on the spec sheet, but in real-world workflows and overall efficiency.
The new M6 chip might sound like a routine generational upgrade, but it's the company's first chip built on a 2nm manufacturing process, which brings meaningful improvements over previous Apple chips.
Gemini Notebook’s mobile app now has a built-in recorder for capturing lectures and meetings as sources. You can record directly where you’ll use the material, skipping the separate recording app and the file upload afterward.
Google announced the feature on X, highlighting classroom lectures and team meetings as potential uses. It also works for capturing your own thoughts, so you can talk through an idea and bring that explanation into your notebook while it’s still fresh.
In 1950, Alan Turing asked whether machines can think. Rather than argue over definitions, he turned the question into a party game, where an interrogator trades typed messages with hidden players and tries to work out who is who. Since then, chatbots have gotten so good that they have already fooled humans in modern versions of the test.
So, four researchers from Paris Cité University asked the obvious follow-up question in a new study published in Computers in Human Behavior Reports: can AI at least catch its own kind?
