If you've been debating whether to pick up some Apple AirTags, now might be the time finally to go for it. The AirTag 4-pack currently has a 20 percent discount, dropping from $100 to $80. Not only does this bring the pack close to its all-time-lowest price, but it makes each AirTag only $20 — $8 less than buying one on its own. So, in a sense, it's a buy three get the fourth free sale, with four extra dollars saved for a coffee.

AirTags pair to your iPhone or iPad in one tap with their live location available in the Find My app alongside your friends and other devices. Its small frame — about an inch and a quarter in length and width — is water and dust resistant with an included battery that requires replacing about once a year. You can get detailed instructions to reach your AirTag on newer iPhone models thanks to Ultra Wideband technology or put it in "Lost Mode" to immediately receive notifications if it pings off another person's device.

You can slip your AirTag into your wallet or purse as is or pick up a case to connect it to your keys or pet's collar. Either way, it's one of the better Bluetooth trackers on the market, especially at such a low price.

Hello Games made an exciting announcement at Apple's Worldwide Developer Conference in 2022: No Man's Sky would eventually be making its way to Macs. Now, as we ramp up towards WWDC 2023, the time has come with Mac gamers finally able to play No Man's Sky to their heart's content. Hello Games claims to have worked closely with Apple to bring the game to life and supports the company's Metal 3 API to reportedly "achieve console quality graphics whilst maintaining battery life on laptops and lower end devices."

No Man's Sky is available for anyone who has a Mac with Apple silicon (which started rolling out in 2020) or an Intel-based Mac with at least a Core i5 processor. There's no need to re-buy the game if you already have No Man's Sky through Steam on your PC, as you can cross-save your progress to jump between devices without backpedaling on your progress. Mac users also have access to cross-play, so you can join gamers on Xbox, PlayStation 4 and 5, PC or VR.

The expansion to Mac follows a few significant updates to the game, including a redesign of the HUD and user interface and a new storyline called Interceptor that brought better visuals and new VR controls. Steam users can download No Man's Sky today, but will be available in the Mac App Store "shortly."

Polestar has announced its latest over-the-air upgrade for the Polestar 2 EV, and it includes an integrated YouTube app right on the home screen. Volvo, a part-owner of Polestar, first mentioned its plan to make YouTube available for its infotainment in 2022 — though it was through the Play Store. While you don't want to be watching YouTube videos as you cruise down the road (or play video games, Tesla), Polestar specifically denotes it as a way to entertain yourself while the car charges. 

Yes, the update is solely so you can amuse yourself while sitting in the stationary car, but sure, when you drop a minimum of $40,000 to $50,000 on an EV, why shouldn't it provide entertainment while juicing up? 

There are also some new features for when you hit the road, including Apple CarPlay's expanded information about calls or media on the home screen. Plus, you can control calls through the steering wheel (as you can in most cars) and, more uniquely, see calls and Apple Maps right on the driver display. 

The last bit of Polestar 2's updates focus the Range Assistant app, with a major upgrade giving you more control over your energy efficiency, with consumption monitoring extended beyond 20, 40, or 100 miles. The update also factors environmental changes and related variables into your projected range — with real-time information available right on the driver display. Previously, this figure was a default range projection rather than one specific to you. The P2.9 over-the-air update has begun rolling out, so keep an eye out for when it reaches your EV.

It's officially the end of an era for the original Google Chromecast, with the first-generation model no longer receiving any updates or support, 9to5Google reports. Chromecast first came on the scene in 2013 as a key-sized device that promised to provide a Smart TV experience for $35, and it has done just that. Google has upgraded the initial Chromecast's hardware throughout the years to keep up with streaming denands but is now leaving it behind for good.

In a release on Chromecast's informational hub, Google asserted that "Support for Chromecast (1st gen) has ended, which means these devices no longer receive software or security updates, and Google does not provide technical support for them. Users may notice a degradation in performance." Google last updated Chromecast's support page back in April, meaning the announcement has gone unnoticed for some time now. 

Through the lens of Google alone, a complete pull-back on the 10-year-old Chromecast original has been a long time coming. The company has only looked after the first-gen's bug and security issues (rather than larger-scale updates) since 2019. The last update came in November 2022 and was the first in three years. Google has also released newer versions since the first-gen, like the cheaper $30 Chromecast with Google TV (HD) and the $50 4K model. 

If you're a loyal first-gen Chromecast user, the only thing to do now is to make sure it's fully upgraded and hope for the best. 

WhatsApp's newest update takes a page out of work-centric video call platforms like Zoom and Microsoft Teams. The messaging app is in the process of rolling out a screen sharing feature that will record and display the contents of your screen with whoever is on the other end of the video call, WABetaInfo reports.

An icon of a phone with an arrow pointing out of it represents the feature and sits alongside longstanding tools like switching cameras, muting and disabling video that appear at the bottom of WhatsApp calls. Once you click the new button, a prompt appears asking if you want to "Start recording or casting with WhatsApp?" alongside a disclaimer that the company will have access to any passwords, photos or payment details you display. If you're okay with that, all that's left is to click "Start now." You can then stop sharing your screen at any time during the call.

Screen sharing is only available to select Android beta testers right now but should roll out to more users in the coming weeks. However, it might not work on older Android models, bigger group calls or with people who don't have WhatsApp's latest version downloaded. If you have an iPhone or iPad and don't feel tied to WhatsApp, Apple baked a similar screen sharing feature into FaceTime calls in January.

If you're in the market for a quality controller without breaking the bank, now might be a good opportunity. Microsoft's Xbox Elite Series 2 Controller in black is 19 percent off, dropping from $180 to $145. Though it's not the lowest we've seen, it's still a decent-sized drop from its retail price. 

The Xbox Elite Wireless Controller Series 2 is a solid option for Xbox gamers, regardless of your system of choice, as it's compatible with Xbox Series X|S, Xbox One and Windows 10 or 11 devices through Xbox Wireless or Bluetooth. There's also an option to connect it with an included USB-C cord. You can swap parts like D-pads and paddles, save up to three unique profiles to the controller and explore button mapping options through the Xbox Accessories app. It also holds up to 40 hours of battery life.

Microsoft's Xbox Wireless Headset is also on sale, down from $100 to $85 — a 15 percent discount. The headphones are compatible across the same systems as Xbox's wireless controller, such as Xbox Series X|S. Additional features include auto-mute, voice isolation and up to 15 hours of battery life. The headphones have sound technologies like Dolby Atmos and Windows Sonic, with volume control dials located on the left earcup.

The wireless headset is still a good $40 more than its wired counterpart, but if free movement is important to you, the discount certainly helps. If you're looking to update all your accessories for the summer, the sale brings the total price of the wireless headset and controller to $230 — saving you $50 overall.

Amazon is running a sale on two Samsung Galaxy tablets for a limited time: the Tab S8+ and the Tab S6 Lite. The 128GB Galaxy Tab S8+ with Wi-Fi has reached an all-time low with a 33 percent cut dropping the price from $900 to $600. The sale is for the Pink Gold model only and includes an improved Samsung S Pen, with a latency of only 2.8ms, compared to prior models' 9ms.

The Samsung Galaxy Tab S8+ as a whole was well-reviewed by Engadget when it came out in 2022. The 12.4-inch OLED display, 2,800 x 1,752 screen and microSD trays made it stand out against its competitors. It's also smaller than its predecessors at 1.24 pounds with a 0.22-inch thickness and, Samsung claims, has a 33 percent harder frame than the S7 models. According to our tests, the 10,090 mAh battery will last for about six and a half hours of regular use.

There's no denying that, even at $600, the Galaxy Tab S8+ is still an expensive purchase. If you're looking for a simpler — and much cheaper – option, the 128GB Galaxy Tab S6 Lite is currently on sale for 37 percent off. While it's an older tablet, we can say it scored highly in our review back in 2020. For $270, you get a 10.4-inch display, 2000 x 1200 screen, a 7,090 mAh battery, and weighs in at about one pound. Plus, it also includes an S Pen with your purchase.

The Galaxy Tab S6 Lite sale is the same across the three available colors, Oxford Gray, Chiffon Rose and Angora Blue. Though the 64GB model is also discounted, the $160 price drop actually makes the 128GB cheaper than its smaller alternative.

Microsoft has called for the US federal government to create a new agency specifically focused on regulating AI, Bloomberg reports. In a Washington, DC-based speech attended by some members of Congress and non-governmental organizations, Microsoft vice chair and president Brad Smith remarked that "the rule of law and a commitment to democracy has kept technology in its proper place" and should do so again with AI. Another part of Microsoft's "blueprint" for regulating AI involves mandating redundant AI circuit breakers, a fail-safe that would allow algorithms to be shut down quickly.

Smith also strongly suggested that President Biden create and sign an executive order necessitating that the National Institute of Standards and Technology's (NIST) risk management framework be followed by any federal agencies engaging with AI tools. He added that Microsoft would also adhere to the NIST's guidelines and publish a yearly AI report for transparency.

Microsoft's calls for regulation follow similar remarks from OpenAI and Google. OpenAI CEO Sam Altman testified before Congress that a "new entity" is needed to regulate AI and recommended "independent audits" of models. Yet, Altman previously suggested pulling OpenAI from the European Union if the company doesn't agree with new policies. 

Kent Walker, CEO president of global affairs for Google and Alphabet, recently released a statement calling for "broad-based efforts — across government, companies, universities, and more — to help translate technological breakthroughs into widespread benefits, while mitigating risks." Concerns about AI have also led to people walking away from its development. Former Google VP and engineering fellow Geoffrey Hinton, commonly referred to as "The Godfather of AI," notably resigned in April to openly warn about AI's risks.

Alongside voicing his concerns, Smith's hour-long speech also served as an opportunity for him to laud recent AI advancements. He compared its significance to that of the printing press or electricity. In an accompanying blog post that echoed his speech, Smith went so far as to say, "AI offers perhaps even more potential for the good of humanity than any invention that has preceded it."

OpenAI first launched its ChatGPT iOS app across the US in mid-May and now it has made good on its promise to expand to more countries in the "coming weeks" by launching in 11 new countries. The countries are a global mix with iOS users in Albania, Croatia, France, Germany, Ireland, Jamaica, Korea, New Zealand, Nicaragua, Nigeria and the UK now able to access the app.

The ChatGPT app works and looks like the website does with conversation history synced between the computer and iPhone. ChatGPT Plus subscribers can access GPT-4 through the app and receive faster responses. The app does have one new feature compared to the website, allowing people to use voice input through OpenAI's Whisper speech recognition. For now, it's only formatted for iPhones, so iPad users still need the desktop version.

As for when ChatGPT will be available on smartphones globally, OpenAI says "soon." Keep in mind there still isn't a ChatGPT app available for Android users anywhere, though OpenAI's original iOS app announcement said, "Android users, you're next!"

The expansion itself and continually easing access to AI hastens the global debate over policies. According to Reuters, Sam Altman, OpenAI CEO, has expressed the possibility of pulling ChatGPT from the European Union if the company decides it can't work within upcoming regulations. Meanwhile, Alphabet CEO Sundar Pichai is working closely with the European Commission to enact AI guidelines.

WhatsApp has been rolling out a constant stream of updates lately across its platform. The latest news comes in the form of a profile update, with WhatsApp reportedly working on a new username option, WABetaInfo reports. Included in the latest WhatsApp beta for Android update is a new field in the profile section of the app, which asks users to choose their own unique handle.

The added option brings WhatsApp one step closer to how people communicate on fellow Meta-owned app Instagram, though not much is known about how a username will work on the messaging app. It could mean a significant change in how people find each other on WhatsApp and increase their privacy — instead of a person needing to share their personal phone number or QR code to chat, a user-chosen username might be enough. End-to-end encryption is said to still be deployed on WhatsApp conversations started by username.

This announcement comes on the heels of another sought-out feature release: message editing. The update allows WhatsApp users to alter a message within 15 minutes of sending it, with the caveat that it will have the word "edited" written beside the timestamp. The messaging app also rolled out "Chat Lock" in May, a tool that lets you make specific one-on-one or group chats available solely through entering your password or biometric scanning. It also stops messages from popping up as notifications.

As for usernames, WhatsApp has yet to set a release date or even confirm the feature. It will likely be offered to beta users first when it does arrive before rolling out across all devices.
