Cut those awkward heart-rate-monitor straps with TomTom’s Runner Cardio GPS watch

By Lee Crane Published April 7, 2014

Runners tired of licking their heart-rate-monitor straps and girding them to their chests before every run will finally be freed from that ritual with TomTom’s new Runner Cardio and Multisport Cardio GPS watches. That’s because the latest version of the Amsterdam-based company’s fitness GPS watches now feature built-in optical heart rate monitoring technology from Mio. Using a light on the back of the watch, the Mio monitors changes in blood flow and tracks heart rate without the use of extra straps or sensors.

This technology also makes it easier for athletes to stay on target by displaying heart rate and using alarms to notify the runner when a certain heart rate has been reached. The Runner places heart rates into five zones: sprint, speed, endure, fat burn, and easy. Set the target and the watch does the rest … well, except for the running.

Like the previous versions of the Runner, the Cardio version tracks and display pace, speed, distance, and calories burned. The Multisport Cardio connects to cycling sensors like speed and cadence using Bluetooth Smart. After the run or ride all the data can be uploaded to Web fitness-tracking sites like TomTom’s MySports, MapMyFitness, RunKeeper, TrainingPeaks or Strava so athletes can let friends or coaches see all the hard work they’ve been doing.

The Runner Cardio is available now for pre order on the TomTom website for $270. The Multisport, which also connects to Bluetooth Smart cadence and speed sensors is $300.

The Apple Car may be dead, but it became the foundation of Apple Intelligence

A decade of work on a canceled car project reportedly laid the groundwork for Apple Intelligence.

Apple Intelligence in Apple Car

The Apple Car may have never left the garage, but it apparently gave birth to Apple's AI ambitions. According to Bloomberg's Mark Gurman, Apple's canceled autonomous vehicle project, one that consumed more than a decade of work and over $10 billion before being scrapped in 2024, ended up laying the technological foundation for Apple Intelligence. In a rather ironic twist, one of Apple's most expensive failures may also become one of its most important long-term investments.

Researchers hid a prompt injection inside a PNG, and AI fell for it

Hacker

AI coding assistants like Claude are becoming every developer's favorite coworker. They can review code, explain confusing functions, and even write entire features with a single prompt. But new research suggests that this growing trust could also become their biggest weakness.

A team of security researchers (professor Sudipta Chattopadhyay and researcher Murali Ediga) has demonstrated an unusual attack that doesn't target the AI model directly. Instead, it targets what the AI doesn't pay enough attention to during code reviews. Rather than hiding malicious instructions in lines of code, the researchers tucked them inside an image file. Since many AI review tools treat images as decorative assets rather than as something worth inspecting, the pull request can appear perfectly harmless and sail through the review.

AI has already fallen into the wrong hands and they’re using it to make bombs

Artificial intelligence has quickly become the go-to tool for everything from writing emails and summarizing meetings to helping students study or developers debug code. But the same technology that saves people time can also be misused, and a new report suggests that terrorist organizations are finding ways to do exactly that.

According to a research paper shared with The New York Times ahead of its publication, researchers found evidence that members of Boko Haram have been using popular AI chatbots to support both day-to-day activities and combat-related tasks. Interviews with 27 former members conducted in Nigeria over the past two years suggest that tools such as ChatGPT, Gemini, Claude, Grok, Meta AI, and DeepSeek were used to gather technical information, troubleshoot weapons, and even assist with planning attacks.
