2026 will be the year of AI slop apps and the world is not going to be a better place because of it.

It's kinda hilarious to watch people accusing each other of being from a certain part of the world by sharing screenshots of profile details.

Gemini 3 is really impressive.

At 30K miles, my car's engine light came on when I reached to Nashville. Thought it was bad gas, it started to blink when I was in Little Rock. Fortunately, I was able to reach Dallas. Replaced the cylinder head. Thanks @MercedesBenz of Grapevine.

[Emrah Usar @emrahusar]

I will be on a road trip from NYC to Dallas with a stop in Nashville. Looking forward to seeing old friends.

@Apple @AppleSupport WhatsApp UX is far better than iMessage

[Emrah Usar @emrahusar]

WhatsApp UX, especially media handling and controls, is better than iMessage. In FaceTime, my camera should cover the entire screen as opposed to overlay the caller's camera. Take note @Apple @AppleSupport

I was able to use LLM over DNS on my recent @Delta flight.

Claude is making sure to share credit if you let it commit the changes. It's the right thing to do

@LinusEkenstam China is a trade surplus country mainly because of their labor force that contributed significantly to their economy over the decades. It's no surprise they can manufacture cars at this scale.

[Emrah Usar @emrahusar]

China is aware of the risks associated with being a trade surplus country, they have been successfully managing it for decades mainly with their global multi-billion dollar infrastructure investments and projects with their trade partner countries.

[Emrah Usar @emrahusar]

Generally speaking China is a trade surplus country, mainly because of their affordable labor force. While that may have clear benefits, like job creation, it also creates risks like over-reliance on external demands.

[Emrah Usar @emrahusar]

Fair, but the reason why they can't do it is not because they lack the knowledge, it is because they don't have the money to do it.

[Ryan Saavedra @RyanSaavedra]

CIA Director Nominee John Ratcliffe yesterday: “There's only one country in the world that can parallel park a 200-foot rocket booster. The Chinese can't do it. The Russians can't do it. We do it.”

New soccer rule! 🚨 Listen up @FIFAcom! Inside the penalty zone and only for corner kicks, allow opposing team’s goalkeeper handle or touch the ball. This would bring more excitement to the game introducing new strategic and unique elements especially during set-piece situations.

Everything Everywhere All at Once is a good movie.

$150 for drone permit is ridiculous. This is rather to discourage people from flying drones in NYC.

[Mayor Zohran Kwame Mamdani @NYCMayor]

We're using the best technology available to #GetStuffDone, including drones!

We've seen them safely inspect building collapses, and now we're opening up the possibilities with a new set of responsible rules for drone usage.

Bias in AI is not a technology problem but rather a human problem. Humans are inherently conditioned to be biased which is reflected in everything we create. We need to adapt new perspectives in ML algorithms to curb human bias.
