Meta chief expertise officer Andrew Bosworth took to his Instagram to clarify, in additional technical element, why a number of demos of Meta’s new smart-glasses expertise failed at Meta Join, the corporate’s developer convention, this week.
Meta on Wednesday launched three new pairs of sensible glasses, together with an upgraded model of its present Ray-Ban Meta, a brand new Meta Ray-Ban Show that comes with a wristband controller, and the sports-focused Oakley Meta Vanguard.
Nonetheless, at completely different factors through the occasion, the dwell expertise demos didn’t work.
In a single, cooking content material creator Jack Mancuso requested his Ray-Ban Meta glasses how you can get began with a specific sauce recipe. After repeating the query, “What do I do first?” with no response, the AI skipped forward within the recipe, forcing him to cease the demo. He then tossed it again to Meta CEO Mark Zuckerberg, saying that he thinks the Wi-Fi could also be tousled.
In one other demo, the glasses failed to choose up a dwell WhatsApp video name between Bosworth and Zuckerberg; Zuckerberg ultimately had to surrender. Bosworth walked onstage, joking concerning the “brutal” Wi-Fi.
“You practice these things like a hundred times, and then you never know what’s gonna happen,” Zuckerberg mentioned on the time.
After the occasion, Bosworth took to his Instagram for a Q&A session concerning the new tech and the dwell demo failures.

On the latter, he defined that it wasn’t really the Wi-Fi that induced the difficulty with the chef’s glasses. As a substitute, it was a mistake in useful resource administration planning.
“When the chef said, ‘Hey, Meta, start Live AI,’ it started every single Ray-Ban Meta’s Live AI in the building. And there were a lot of people in that building,” Bosworth defined. “That obviously didn’t happen in rehearsal; we didn’t have as many things,” he mentioned, referring to the variety of glasses that have been triggered.
That alone wasn’t sufficient to trigger the disruption, although. The second a part of the failure needed to do with how Meta had chosen to route the Dwell AI visitors to its improvement server to isolate it through the demo. However when it did so, it did this for everybody within the constructing on the entry factors, which included all of the headsets.
“So we DDoS’d ourselves, basically, with that demo,” Bosworth added. (A DDoS assault, or a distributed denial of service assault, is one the place a flood of visitors overwhelms a server or service, slowing it down or making it unavailable. On this case, Meta’s dev server wasn’t set as much as deal with the flood of visitors from the opposite glasses within the constructing — Meta was solely planning for it to deal with the demos alone.)
The problem with the failed WhatsApp name, alternatively, was the results of a brand new bug.
The sensible glasses’ show had gone to sleep on the actual second the decision got here in, Bosworth mentioned. When Zuckerberg woke the show again up, it didn’t present the reply notification to him. The CTO mentioned this was a “race condition” bug, or the place the end result will depend on the unpredictable and uncoordinated timing of two or extra completely different processes attempting to make use of the identical useful resource concurrently.
“We’ve never run into that bug before,” Bosworth famous. “That’s the first time we’d ever seen it. It’s fixed now, and that’s a terrible, terrible place for that bug to show up.” He careworn that, after all, Meta is aware of how you can deal with video calls, and the corporate was “bummed” concerning the bug exhibiting up right here.
Regardless of the problems, Bosworth mentioned he’s not fearful concerning the outcomes of the glitches.
“Obviously, I don’t love it, but I know the product works. I know it has the goods. So it really was just a demo fail and not, like, a product failure,” he mentioned.
