The Raspberry Pi Pico is a compact microcontroller board featuring custom RP2040 silicon with dual Arm Cortex-M0+ cores running at up to 133 MHz, 264 KB SRAM, 2 MB flash memory, 26 GPIO pins, and three ADC channels, making it suitable for real-time signal processing tasks like Morse code decoding.

The device captures audio using the Pico's built-in ADC, resamples the signal, applies Fast Fourier Transform (FFT) for frequency analysis, uses narrow filters to improve signal-to-noise ratio, and employs a Bayesian decoding pipeline with typo corrections to handle noisy real-time multi-channel Morse code from sources like SSB receivers.

The first three-day test runs from Wednesday, February 11 to Friday, February 13, 2026, at Bahrain International Circuit, with on-track action daily from 10:00 local time (07:00 GMT) to 19:00 local time (16:00 GMT), including a one-hour lunch break from 14:00-15:00 local.

TV coverage is limited to the final hour of running each day on channels like Sky Sports F1 (from 3pm UK time for the afternoon session); full sessions may be available via select livestreams, but comprehensive live streams for all hours are not universally broadcast.

The spangram is a word or short phrase that describes the puzzle's theme and spans two opposite edges of the grid. It highlights in yellow when found, while theme words turn blue.

Finding three non-theme words grants a hint that highlights the letters of one theme word. Every letter in the grid is used exactly once, with no overlapping words.

The objective is to sort 16 words into four groups of four, where each group shares a specific common theme or category, often involving wordplay.

The colors indicate difficulty levels: yellow for the easiest category, green for medium, blue for harder, and purple for the most challenging, often with wordplay.

If a guess contains multiple instances of the same letter, they are marked green or yellow only if the answer contains that many instances; extra occurrences are marked gray. Letters can appear more than once in both the guess and the answer.[2][4]

Hard mode requires all revealed green or yellow letters to be included in subsequent guesses, unlike normal mode where this is optional. It does not change the answer but enforces reuse of known letters.[2][4]

The iTunes Wish List is a legacy feature for saving movies and TV shows to buy or rent later, also referred to as Favorites on tvOS. Apple is discontinuing it soon as users are encouraged to migrate to the modern Apple TV Watchlist, with the feature no longer being accessible on Apple platforms.

Apple sends an email to affected users with a PDF attachment containing links to the saved movies and TV shows. Users should follow the links and tap the + button to add each item to their Apple TV Watchlist, where it will appear in the Continue Watching row on the Apple TV app Home tab.

An APU (Accelerated Processing Unit) is a system-on-chip that integrates CPU and GPU cores on a single die, ideal for laptops and handhelds. High memory bandwidth is crucial for Medusa Halo's powerful RDNA 5 iGPU and AI workloads like LLM inference, as it determines how quickly data can be accessed by the shared unified memory.

LPDDR6 is the next-generation low-power DRAM standard for mobile devices, supporting speeds up to 14,400 MT/s. On Medusa Halo's 256-bit bus, it delivers 460.8 GB/s bandwidth—an 80% increase over Strix Halo's 256 GB/s LPDDR5X—potentially rising to 691.2 GB/s with a rumored 384-bit bus.

The maximum price of $4,299 applies to the full retail cost of the flagship model with AMD Ryzen AI Max+ 395 processor, 128GB RAM, and 2TB storage, while early-bird pricing on Indiegogo is $3,499 for this config.

The 116Wh battery exceeds the typical 100Wh airline limit for carry-on lithium batteries without special approval, requiring passengers to obtain clearance for flights.

YouTube Music's AI Playlist feature uses Google's Gemini models combined with YouTube's extensive music catalog to interpret user prompts about moods, genres, or musical preferences. The system analyzes metadata, artist networks, and user listening history to generate customized playlists. Users access the feature by tapping the 'New' button in the Library tab, selecting 'AI Playlist,' and entering a text or voice prompt describing the type of music they want—such as 'upbeat indie for a road trip' or 'melancholic jazz for rainy afternoons.' The AI then assembles a matching playlist that users can refine by removing tracks and saving customized versions to help the system learn their preferences.

YouTube Music's AI Playlist feature is exclusively available to Premium subscribers as part of Google's strategy to make its Premium plan more attractive to users. The feature requires a Premium subscription ($10.99 per month or $109.99 per year) that includes ad-free music, background play, and offline downloads. YouTube is not alone in this approach—Spotify has been testing its own 'Prompted Playlist' feature since late 2025, and Apple Music rolled out natural language search capabilities in the previous quarter. Amazon Music and Deezer have also launched AI-powered playlist or radio features. However, YouTube has a unique advantage: its massive catalog includes official releases, live performances, remixes, and user-uploaded content that other services cannot access, potentially enabling more adventurous and diverse AI-generated playlists.
