Engineering in the Era of Agents with Yechezkel Rabinovich

Modern software platforms are increasingly composed of diverse microservices, third-party APIs, and cloud resources. The distributed nature of these systems makes it difficult for engineers to gain a clear view of how their systems behave, which can slow down troubleshooting and increase operational risk. groundcover is an observability platform that uses eBPF sensors to capture

Fortnite Developers Can Now Create AI Characters — Just Don’t Try to Date Them

Following last year’s AI-powered Darth Vader in Fortnite that swore in a re-creation of James Earl Jones’ voice, Epic Games is now letting Fortnite creators experiment with a new “conversations” tool to create AI-powered characters that players can talk and interact with. “Instead of authoring dialogue trees for characters in your islands, conversations transforms an […]

Causes of the Red Ring on Certain Apple Watch Digital Crowns

as noted in our 2024 assessment. In the latest models, the Digital Crown highlight became an orange circle that is exclusively available for Apple Watch Ultra editions. Prior to that, for several years, Apple introduced a prominent red dot on the Digital Crown to indicate that the model included cellular capabilities — which made it slightly pricier.

On the Series 3, in 2017, the red dot served as a significant differentiator between the GPS and cellular models. In 2018, Apple revamped the design to the red ring that has been featured in most Apple Watches over the last ten years. This indicated that the company would provide a variant of the aluminum Apple Watch Series and Apple Watch SE without the red ring, while consistently including it on the stainless steel and titanium versions of its wearables.

Apple Sports Unveils Initial Pair of CarPlay Widgets: Setup Instructions Provided

Apple has enhanced its Sports app for iPhone, adding support for CarPlay and new features for Formula 1 (F1) enthusiasts. The newest version, Apple Sports 3.10, represents the app’s initial integration with CarPlay, enabling users to retrieve sports information directly from their vehicle’s dashboard.

### Apple Sports on CarPlay

This update does not provide a standalone CarPlay app; however, it incorporates two small widgets that can be used within the CarPlay interface: My Teams and Leagues. These widgets allow quick access to preferred teams and league standings.

To set up these widgets, users need to go to the Settings app on their iPhone: Settings > General > CarPlay > My Car > Widgets. There, they can add the Sports app widgets to their CarPlay widget stack. The My Teams widget shows teams based on user preferences configured within the Sports app, while the Leagues widget can be tailored to display specific leagues by tapping the “i” icon in the widget settings.

CarPlay can support one to three widget stacks, depending on the resolution of the car’s display. Users may be able to enable an additional widget stack by turning on Smart Display Zoom in the CarPlay settings.

Besides the CarPlay functionalities, the Sports app also includes medium and large versions of the My Teams and Leagues widgets for iPhone users.

### New F1 Features and World Cup Tracking

The update additionally introduces thrilling new features for F1 fans. Users can now check weather conditions for each Grand Prix, such as track temperature and wind speed, enriching the experience for followers of the races.

Moreover, the Sports app is preparing for the 2026 FIFA World Cup with new tracking options. Users can monitor their favorite teams and view group standings leading up to the tournament, which is scheduled to commence in June.

Apple Sports for iPhone is available at no cost on the App Store, making it readily available for sports enthusiasts wanting to keep up with their favorite teams and events.

This is in stark contrast to the earlier macOS 26.4, which introduced several new features, such as a battery charge limit and a compact tab view in Safari.

The current macOS 26.5 public beta 3 is accessible with build version 25F5058e, and users are prompted to investigate the system for any pertinent updates.

### How to Install the New Beta

For those keen on testing out the macOS Tahoe 26.5 developer beta 3, adhere to these instructions:

1. **Backup your Mac**: Safeguard your data before moving forward.
2. **Open System Settings**: Access the settings on your Mac.
