Vigorous, entertaining and punchy sound Good looks and plenty of different finishes Take a fair amount of running in Dali may have been concentrating on the loftier parts of the audio market lately with its various loudspeaker and headphone product launches, but with the Kupid it wants you to know it hasn't abandoned the entry level. The company has had plenty of success with its affordable speaker ranges before now, and it wants to bring those days back. The DALI Kupid standmount loudspeakers launched in October 2025, and in the United Kingdom they cost "299 per pair. In Australia they're a predictable AU$599, while in the United States they cost a slightly less predictable $599. The American market is…...

Besides these challenges, we also had to make sure that the things that customers had already been using Alexa for, dropping in at home, checking in on your grandma and how she's doing, using your smart home routines that you've set up and use every day from the morning, all of these had to work seamlessly. Let's take a look at what we had to do to get Alexa to where it is with Alexa+. You saw an example in the video about asking if someone let the dog out. Let's talk about a real example in this case. We have a dog named Daisy. She's a cream golden retriever. And when we go…...

And to start with, I'd like to introduce myself. So my name is Cal, and I joined Anthropic two years ago to help start a team that we call Applied AI. The Applied AI team's mission is to help our customers and partners build great products and features on top of Claude. And so back then, a lot of the work I did in the early 2024 days was helping customers build Q&A chatbots, some sort of RAG system. You go grab some help center articles that might be relevant. You take the user question, you put them in the prompt, and then you say, all right, Claude, try to answer this with these…...

You don't need to manually install anything else unless you want additional components....

This process helps us identify patterns or natural groups hidden in our data without any prior knowledge of the expected outcomes. Clustering is useful for various tasks, such as: How K-Means Clustering Works The k-means algorithm is a popular clustering technique that partitions the data into k clusters based on their similarity. Here's a high-level overview of how it works: To implement k-means clustering, we need to choose an initial set of centroids and decide on a distance metric (usually Euclidean or Manhattan). We'll use the scikit-learn library in Python for our implementation: Choosing the Optimal Number of Clusters (K) One crucial aspect of k-means clustering is determining the optimal number of clusters (k). There are several methods for choosing k, including: While…...

How many of you, raise your hands, stream with more than one device? Probably most of you. It looks like most of you. So I stream with my phone, my laptop, my TV, my tablet, and that creates a lot of complexity at Prime Video. We have to support a number of form factors and backgrounds on top of 30+ languages in over 200 territories. and so what may pass one evaluator may not pass another, and that data can leak into our datasets and make it more difficult to use. And then once we have a solution, the evaluation can take a while. We can take several days to run it over a dataset and then figure out what…...

While a word is a naturally occurring, linguistically defined unit-a lexical item understood by human users-the token is a dynamic, computationally optimized, and often fractional unit derived through sophisticated statistical and algorithmic methods. #summary-the-disparity-between-human-language-and-ai-input Summary: The Disparity Between Human Language and AI Input The distinction between a "word" and a "token" is central to understanding the operational mechanics of contemporary artificial intelligence (AI) models, particularly Large Language Models (LLMs).

23+ min ago (159+ words) React gives us two main primitives for storing state: This hook gives React something it never had out-of-the-box: Direct mutation that triggers re-renders " immediately and safely. react-use-current is a tiny hook built on top of VRef (vref). It gives React the ability to: " updates instantly " mutates directly " re-renders correctly React developers often hit these problems: useState doesn't update until next render. useCurrent updates instantly. useState forces immutability " slow & annoying. useCurrent allows: ref.current++ won't update UI. useCurrent will. A version of useEffect that auto-tracks dependencies. A version of useMemo that auto-tracks dependencies. Tracking is required for: This mechanism is identical to VRef's change reporters " but adapted for React. Directly mutate nested form fields without cloning. Mutate in place, but still reactive. Play with react-use-current: " Open Live Playground " What do you think? What do you think? Would this help in forms,…...

24+ min ago (1676+ words) Let me guess: you've been promised that AI will revolutionize your content production. Again. And you know what? This time it's actually different. Not because AI suddenly got magical (it didn't), but because autonomous AI agents'tools that can plan, execute, and iterate without constant hand-holding'have crossed a threshold. They're now good enough to scale your content production meaningfully. The catch? If you deploy them wrong, you'll scale mediocrity at impressive speed. I've spent the last eight months testing autonomous AI tools for content production across three different brands. Here's what actually works when you're trying to maintain brand voice while letting the robots do their thing. First, let's clear up the terminology soup. AI agent marketing isn't just "using ChatGPT a lot." It's deploying autonomous systems that can handle multi-step workflows without you micromanaging every decision. Think: an AI that…...
