Are you feeling a bit distracted these days? Is a new remote work situation or job creating problems with task management? Apple added a productivity feature to iOS and related platforms called Focus. Focus allows you to customize certain modes for work, studying, or other activities to avoid distractions. If you haven't tried it, we recommend incorporating it into your most productive times. Focus is more useful than the usual sleep modes or just leaving messages on read.

iMessage remains Apple’s all-purpose message app. If you’re happily ensconced in the Apple world, you probably don’t use social media message apps like WhatApp or Messenger unless it’s the only way to contact friends or family — iMessage takes care of pretty much everything.

Google runs one of the most impressive 3D mapping tools available. It's a reliable go-to for planet zooming, location finding, and basic geo-analysis. But, unlike Google Maps, Google doesn't market it to general users much, so you may not have heard of it. Let's talk about Google Earth Pro, the advanced, publicly available software that lets even casual users play with GIS data or go on a swooping tour of the world.

You may have noticed that Google has invested deeply in AI tools for many years. Lately, it's brought more of those tools to the public, encouraging developers to rely on Google platforms for their complex AI creations.

Apple's Activity app (a.k.a. the Fitness app) is deeply integrated into the Apple ecosystem, capable of storing tons of helpful data for you, your trainer, and your doctor. The fitness app pairs especially well with an Apple Watch. The latest models have extensive sensors to keep track of your heart rate, steps counted, and the oxygen in your blood. Tracking your numbers can help you get your resting heart rate down, get your cardio heart rate up, and increase your calories burned, among other smartwatch-oriented goals.

By 

When you pull out your phone and type in a quick Google search to answer a question, what's really going on? Most of us know that there's some vast Google algorithm behind the scenes that interprets organic search and posts results via a specific ranking. So far, so good. But Google also included a significant amount of AI technology in its search engine, bringing us to RankBrain. RankBrain is a machine learning model that's deeply involved in how Google search results are returned, which means it impacts many of our online lives. Here's an overview of how it all works.

It seems like everyone has a new high-tech headset these days. It's a technology we keep returning to, looking for new ways to use or present it to consumers. It's been almost 19 years since Google Glass died of embarrassment (although that AR project was only officially shuttered in 2023), and now Apple is taking its turn with the Vision Pro. Meanwhile, Microsoft has HoloLens, while Vive and Oculus have been around for years, and there are kid-friendly goggles you can strap a high-quality Android phone to in an imitation of a full VR experience.

The world of AI creation seems like it's jumped forward decades in only a couple of years because of tools like ChatGPT and Midjourney. However, these user-friendly apps have long-term foundations in technology and research that were carefully put together by programmers over time. That yields incredible tricks, whether it's ChatGPT imitating a president or Midjourney creating surreal artwork.

Google has recently begun offering a large suite of AI tools to everyday businesses and ambitious software products that use Google platforms, perhaps from a capable Chromebook. One interesting example in the past few years is Google Cloud's AutoML Vision. This tool to create image analysis models may soon shut down for Vertex AI's rollout. However, you can still learn how it works and how to prepare data, which will be invaluable when using Google's similar future services. Let's look at the details.

If you've heard the name Starlink thrown around the past few years, you may wonder what the deal is. Sure, it has something to do with satellites and Elon Musk, but the details get fuzzy after that.
