THE HARDEST BUG INVESTIGATION OF MY CAREER AND THE INSANE CODE THAT CAUSED IT

A weird bug in an augmented reality system caused disorienting visual glitches and interestingly, only happened every Wednesday. After an extensive, months-long investigation involving robotic arms, lasers, and a high-FPS camera, the root cause turned out to be due to a time-translation hack using day-of-week words in German and English neglecting to account for the German word for Wednesday, "Mittwoch." This oversight led to timestamp discrepancies, resulting in the weekly glitches and an unpredictable error correction mechanism.

DID APPLE JUST KILL SOCIAL APPS?

iOS 18 will allow users to select which contacts to share with an app instead of revealing their entire address book. Apple doesn't think the change will hurt developers, but some startups have seen contact sharing drop significantly since the iOS 18 change. The ability to quickly connect new users with friends can mean the difference between success and failure for apps. This change could mean friend-based social apps may eventually be replaced by apps like TikTok which show users content based on what they like rather than who they're connected to.

GOOGLE IS TAKING ITS RIVALRY WITH OPENAI TO ANOTHER LEVEL

Teams at Google have made progress on software for AI models with humanlike reasoning abilities in recent months. The company is using chain-of-thought prompting, which allows large language models to solve multistep problems using a series of intermediate reasoning steps, to give models the ability to solve more complex math- and company-programming-related inquiries. OpenAI's new o1 model also uses chain-of-thought prompting. Google employees were worried last year that the company had fallen behind in the AI race, but they are now less concerned now that Google has unveiled more products to compete with.

LARGEST BRAIN MAP EVER REVEALS FRUIT FLY'S NEURONS IN EXQUISITE DETAIL

Researchers now have a map of the brain of a single female fruit fly that includes nearly 140,000 neurons and captures more than 54.5 million synapses. The map was described in a package of nine papers by a consortium known as FlyWire, which is co-led by neuroscientists Mala Murthy and Sebastian Seung at Princeton University in New Jersey. It has been in development for more than four years. The map shows how neurons connect through chemical synapses but doesn't offer any information about electrical connectivity between neurons or how neurons chemically communicate outside synapses.
