Substack users woke to a strange surprise today when trying to share links on Twitter, finding an error message when interacting with any tweet featuring a Substack link. Tweets with an outgoing link to Substack cannot be retweeted, replied to or even liked. The error message states that “some actions on this tweet have been disabled by Twitter.” The loss in functionality even extends to tools like TweetDeck.

You can still tweet out Substack links, but that is where engagement ends. This could be a garden variety error, but it could be a response by Musk and Twitter to Substack’s recently-announced Twitter-esque Notes feature. After all, Twitter is no stranger to silencing rivals, both real and imagined. The social network briefly placed restrictions on tweets with outgoing links to Mastodon, Facebook, Instagram and Truth Social, even outlawing outgoing links to other social media profiles in bios. Musk has also experimented with banning journalists who cover Twitter and made other questionable decisions for a self-proclaimed free-speech absolutist.

The founders of Substack issued a response to the move and it certainly seems like they believe the restrictions were instituted on purpose and not part of a system error.

“We’re disappointed that Twitter has chosen to restrict writers’ ability to share their work. Writers deserve the freedom to share links to Substack or anywhere else. This abrupt change is a reminder of why writers deserve a model that puts them in charge,” the founders wrote.

There is another option beyond spite or a system error. It is possible Substack ran afoul of Twitter’s recently-announced API pricing scheme. The sheer number of links to Substack content from users would force the company to invest in the Enterprise-level API at $42,000 a month. If Substalk balked about these costs and Twitter caught wind of it, this could be another New York Times checkmark situation.

Substack says it is currently investigating the newly-imposed restrictions and that it will “share updates as additional information becomes available.” The company shared a blog post in which it expressed hope that these moves were made in error and stated that "cracks are starting to show in the internet’s legacy business models." We reached out to Substack and will update this post if the situation changes or if functionality is restored.

The 16×2 LCD display is a classic in the microcontroller world, and for good reason. Add a couple of wires, download a library, mash out a few lines of code, and your project has a user interface. A utilitarian and somewhat boring UI, though, and one that can be hard to read at a distance. So why not spice it up with these large-type custom fonts?

As [Vaclav Krejci] explains, the trick to getting large fonts on a display that’s normally limited to two rows of 16 characters each lies in the eight custom characters the display allows to be added to its preprogrammed character set. These can store carefully crafted patterns that can then be assembled to make reasonable facsimiles of the ten numerals. Each custom pattern forms one-quarter of the finished numeral, which spans what would normally be a two-by-two character matrix on the display. Yes, there’s a one-pixel wide blank space running horizontally and vertically through each big character, but it’s not that distracting.

Composing the custom patterns, and making sure they’re usable across multiple characters, is the real hack here, and [Vaclav] put a lot of work into that. He started out in Illustrator, but quickly switched to a spreadsheet because it allowed him to easily generate the correct binary numbers to pass to the display for each pattern. It seems to have really let his creative juices flow, too — he came up with 24 different fonts! Out favorite is the one he calls “Tron,” which looks a bit like the magnetic character recognition font on the bottom of bank checks. Everyone remembers checks, right?

Hats off to [Vaclav] for a creative and fun way to spice up the humble 16×2 display. We’d love to see someone pick this up and try a complete alphanumeric character set, although that might be a tall order with only eight custom characters to work with. Then again, if Bad Apple on a 16×2 is possible…

Outdoor pizza ovens are having a moment. The compact, portable models have become popular for both novice and pro cooks alike, allowing them to host casual pizza parties or cater events as part of a restaurant business. While the wood- and gas-burning ovens can be fun to use for all skill levels, they have to remain outdoors, and using wood or charcoal requires more attention.

After making some of the best outdoor pizza ovens, Ooni introduced its first electric model designed for indoor use in March. The Volt 12 ($999) encompasses everything from the company’s existing product line, from high-heat cooking to consistent results, and adds ease of use and baking versatility to the mix. This beast is big and expensive, but it also makes some damn good pizza.

Design

The Volt 12 looks like what I’d expect an electric pizza oven from Ooni to look like. It bears the most resemblance to the Karu 16, one of the largest models the company offers. The gray and black color scheme is on every current Ooni model, except for the all-silver multi-fuel Karu 12. Rather than a rectangle, the Volt 12 has angled corners, making it more of a flat octagon than a boring box. Ooni says the exterior is powder-coated and weather resistant so you can take it outdoors – not that you would want it to get too wet. Since this model is more of a countertop appliance than its open-flame predecessors, the Volt 12 has short, stubby legs rather than the longer, folding ones on the wood- and gas- burning units.

Only three Ooni models have glass doors that allow you to watch the entire cooking process. As an electric, indoor oven, the Volt 12 is one of those. Unlike the Karu 16 and Karu 12G, this panel is gloss black instead of metal. The door has a robust black handle that remains cool to the touch, even at 850 degrees, and a row of three control dials sit beneath the glass window. The only other button is an on/off switch on the left side of the front. This turns off the power completely. When this is switched on, the oven sits in standby mode until you hit the power button on the front that actually gets the Volt 12 ready to use.

On the left is the time dial with the power button above it. The center control is for temperature, which ranges from 350 to 850 degrees Fahrenheit. Lastly, the far right dial is for “balance,” allowing you to shift how much power is given to the top and bottom heating elements. In other words, you can put more emphasis on the stone for a crisper crust or more on the top for a bit more browning/char. The balance control also activates a boost feature that can be used to get the stone to return to target temp quickly between pizzas (it takes about 45 seconds). All three controls are flanked by white lights for precise level indications. During pre-heating, for example, the temperature dial starts at 350 and slowly moves around to your target, blinking along the way at the current status.

The bottom heating element sits underneath the stone – a 13-inch square cooking surface that can accommodate a variety of pans in addition to 12-inch pizza. There’s also an interior light that stays on the whole time, making it very easy to see how things are progressing without having to open the door.

Setup and use

Before the first use, you’ll need to season Volt 12. This requires you to run the oven at full blast (850) for 20 minutes and then allow it to cool before preheating to launch your first pizza. The cooldown takes quite a bit longer than the preheating or 20-minute burnoff, so you’ll want to do thing well before you need to actually cook. The cool down time on the Volt 12 takes a while. While the exterior will be back to room temp sooner, it takes a while for the inside to do the same since the Volt 12 is so well-insulated. This means you’ll have to wait at least an hour to safely store it or put the cover on.

Ooni says the 1,600-watt Volt 12 can hit 850 degrees in 20 minutes where it can cook a pizza in 90 seconds. This makes it slightly slower to achieve max temperature than its wood- or gas-burning counterparts. The Karu 16, for example, can reach 950 degrees Fahrenheit in 15 minutes. Still, 20 minutes is remarkably quick, and in my experience, the Volt 12 actually hit 850 faster than that.

The key advantage the Volt 12 has over its wood-burning siblings is convenience. Those models make great pizza with the subtle flavor of wood fire, but the flames require supervision whereas the Volt 12 is very much set it and forget it. You don’t have to worry about maintaining the fire in between stretching dough, topping pizzas and launching them into the oven. The Volt 12 also sets the balance dial based on your cooking temperature, but you can adjust it if you need to. Most outdoor Ooni ovens have an optional gas burner (propane and natural gas models), which would also remedy some of the headaches with temperature regulation.

Making the pizza

All of this sounds great on paper, but it would be for naught if the thing didn’t make good pizza. Thankfully, Ooni has translated its formula for excellent outdoor cooking to its electric oven. The Volt 12 produces comparable results to any of the company’s other models, right down to the char and leoparding on Neapolitan pies. Since the temperature dial gives you more precise control, it’s easier to achieve the desired cook on everything from New York style to thin-and-crispy. With the extra space inside, you can also make Detroit pan pizza, as well as roast and bake other items with ease. The Volt 12 did well with any type of crust I threw at it, churning out tasty pies consistently in just a few minutes.

Running wide open at 850 degrees, the Volt 12 makes excellent Neapolitan-style pizza. You’ll need to make sure you have a proper dough recipe (Scott Deley’s The Ooni Pizza Project is a great guide), but assuming you're starting with a good base, the oven will do its thing well. I found that the Volt 12 is a little more forgiving with rotating the pies than the open-flame outdoor models, so you don’t need to babysit it quite as much. These pizzas were light and airy with a slight crispness to the bottom and the requisite leoparding. New York-style pizzas baked at 650 were also great, with crisp edges and bottom, with a pleasant chewiness to the crust.

There are some downsides to the Volt 12, the big one being the price. It’s $999, and I’ll be the first to tell you that excellent pizza is achievable with your main oven and a baking stone or steel that costs a fraction as much. The second thing is it’s huge. The Volt 12 takes up the entire depth of the counter and is 20 inches wide. It also weighs just under 40 pounds. That’s not too heavy, relatively speaking, and the Volt 12 can easily be chucked in the backseat for a nearby party. Ooni did design it with built-in handles on the sides though, which makes the task of moving it slightly easier.

The competition

In the US, Ooni’s main competition for the Volt 12 is the Breville Pizzaiolo. This oven has been on the market for a few years at this point, with a design that looks more like one of the company’s toaster ovens. It’s an all-stainless steel aesthetic, with a glass door for viewing and easy-to-use controls up front. Out of the box, the Pizzaiolo runs on a variety of presets for different styles, but Breville also equipped it with a manual mode to give you full control over the top and bottom heating elements.

The three strikes against this alternative are cost, a confining cooking surface and the lack of interior lighting. The Pizzaiolo is $999.95, so unless you find one on sale, you won’t save any money over the Volt 12. The stone on the Pizzaiolo is circular instead of square, so you’ll only be able to use 12-inch round pans in addition to your pizza. And lastly, there’s no light inside, so it can be a challenge to keep tabs on the cooking process. You’ll almost certainly have to open the door at some point for a closer inspection.

Wrap-up

With the Volt 12, Ooni enters new territory by bringing its formula for stone-baked pizza indoors. While the results are consistently great across a range of styles, this is the company’s most expensive product to date, and I can see that being prohibitive for some – no matter how good the pizza is. A Karu 16 with the additional purchase of a gas burner is $920 or $950 (propane vs. natural gas), which would give you the convenience of a control dial with option of cooking with wood. Still not cheap, but that oven is big enough to do more than just pizza, so it’s also quite versatile. What it really comes down to is where you’ll be cooking most often – inside or out – or if you’re just fine upgrading your pizza game with accessories for your kitchen oven. And there’s absolutely no shame in doing that.

Google announced end-of-life dates today for products relying on the Nest app that won’t carry over to the new Google Home. If you own any Nest Secure or Dropcam home-security products, you have a year to use them before they become paperweights. Phasing out old and incompatible hardware could signal that the arrival of Google’s more customizable new Home app is drawing near.

Nest Secure will continue to work until April 8th, 2024. To ease the blow, Google is offering some freebies to customers — as the company often does when its products head to the Google Graveyard. Nest Secure users will receive an offer for a free ADT Self Setup System (up to a $485 value); alternatively, they can opt for $200 in Google Store credit. Google says it will send an email with redemption instructions to eligible users.

Dropcam products will also cease to work after April 8th of next year. Google advises users to download and save their video history before this date to avoid losing it. As consolation for Dropcam customers, the company is offering a free Nest Cam (indoor, wired) for those with a Nest Aware subscription; those without a subscription can take 50 percent off the same camera.

Dropcam

Finally, Works With Nest, the API system allowing third-party integrations with otherwise incompatible smart home accessories, will stop working after September 29th. Google points customers to Assistant-based routines in the Google Home app as a replacement, and it plans to launch a script editor “in the coming months” to make up for other lost features. The company says it’s also “working closely” with partners to provide replacement integrations.

Google announced an updated Home app last October that could be the primary source for today’s hardware cutoff announcements. The updated Home app integrates Matter, including its Fast Pair feature. It’s available now in a public preview.

Nest Secure launched in 2017 as a fresh take on smart home security. Designed to compete with legacy brands like ADT (which Google later invested in), the system included a Guard base, motion-detecting sensors for windows and doors and tag keychains, which let you quickly enable or disable the system. Google announced in 2020 it had discontinued the platform but promised it would continue working for the foreseeable future. Meanwhile, Dropcam began as a pioneering smart home security brand, launching some of the first cloud-connected cameras. Google / Nest bought the startup in 2014 for $555 million, a move that founder Greg Duffy later described as a “mistake.”

NASA has launched an innovative air quality monitoring instrument into a fixed-rotation orbit around Earth. The tool is called TEMPO, which stands for Tropospheric Emissions Monitoring of Pollution instrument, and it keeps an eye on a handful of harmful airborne pollutants in the atmosphere, such as nitrogen dioxide, formaldehyde and ground-level ozone. These chemicals are the building blocks of smog.

TEMPO traveled to space hitched to a SpaceX Falcon 9 rocket launching from Cape Canaveral Space Force Station. NASA says the launch was completed successfully, with the atmospheric satellite separating from the rocket without any incidents. NASA acquired the appropriate signal and the agency says the instrument will begin monitoring duties in late May or early June.

TEMPO sits at a fixed geostationary orbit just above the equator and it measures air quality over North America every hour and measures regions spaced apart by just a few miles. This is a significant improvement to existing technologies, as current measurements are conducted within areas of 100 square miles. TEMPO should be able to take accurate measurements from neighborhood to neighborhood, giving a comprehensive view of pollution from both the macro and micro levels.

This also gives us some unique opportunities to pick up new kinds of data, such as changing pollution levels throughout rush hour, the effects of lightning on the ozone layer, the movement of pollution related to forest fires and the long-term effects of fertilizers on the atmosphere, among other data points. More information is never bad. 

NASA

TEMPO is the middle child in a group of high-powered instruments tracking pollution. South Korea's Geostationary Environment Monitoring Spectrometer went up in 2020, measuring pollution over Asia, and the ESA (European Space Agency) Sentinel-4 satellite launches in 2024 to handle European and North African measurements. Other tracking satellites will eventually join TEMPO up there in the great black, including the forthcoming NASA instrument to measure the planet's crust.

You may notice that TEMPO flew into space on a SpaceX rocket and not a NASA rocket. This is by design, as the agency is testing a new business model to send crucial instruments into orbit. Paying a private company seems to be the more budget-friendly option when compared to sending up a rocket itself. 

For the fifth time in just over three months, Tesla has slashed the prices of its electric vehicles in the US, as Reuters reports. The company has cut prices by up to six percent across its lineup. The Model 3, for instance, is $1,000 less expensive than it was yesterday. It now starts at $41,990, according to Tesla's website.

There are bigger discounts on higher-end configurations. The Model Y Long Range and Performance models have dropped by another $2,000 to $52,990 and $56,990, respectively. The Model S and Model X have already seen major price cuts this year and have dipped by an extra $5,000 to starting prices of $84,990 and $94,990. As Electrek points out, the price of the base Model S has tumbled by $20,000 since 2022, while the Model S Plaid is over $25,000 less expensive than it was a few months ago.

Tesla said this week it delivered almost 423,000 EVs in the first three months of 2023 amid the initial waves of price cuts in the US, China and other countries. That figure marked a company record, as deliveries increased by four percent from the previous quarter. However, Tesla again missed analyst estimates.

The company aims to deliver 1.8 million EVs this year. It's not on track to do that yet based on the first-quarter figures. Although the multitude of price cuts could ultimately boost demand and make Tesla more competitive in an increasingly crowded sector, analysts have noted that the discounts could eat into the company's profit margins given the relatively small increase in deliveries they've spurred to date.

EA will release the mobile free-to-play Lord of the Rings: Heroes of Middle-earth on May 10th, marking its first LOTR game since 2009's The Lord of the Rings: Conquest. It also unveiled the first real trailer, showing gameplay, menus and more. It's one of five LOTR games currently in development from Embracer (which bought the rights last year), including the much anticipated Lord of the Rings: Gollum set to arrive shortly afterwards. 

The trailer features a "stylized realism art style," EA wrote, leaning into existing lore with wanderers, warriors, wizards and other classic LOTR characters. AT the same time, it creates "a more diverse and inclusive Middle-earth," the company said, while showing off Story, PVP and other gameplay modes.  

Heroes of Middle-earth includes characters from both The Lord of the Rings and The Hobbit, along with collection systems, turn-based combat and more. In a previous news release, EA said that players will experience "iconic stories from the world of Tolkien and take up the fight against the great evils of Middle-earth." Given the free-to-play aspect, there are of course microtransactions.

Heroes of Middle-earth is set to arrive on iOS and Android on May 10th, with pre-registration now open. Meanwhile, Lord of the Rings: Gollum will launch on consoles and PC May 25th, and Embracer reportedly has three additional titles in development for the next two years. 

It's Friday, which means it's time for another roundup of good tech deals. Today's highlights include Amazon's Kindle Paperwhite back down to $100, which is within $5 of the popular e-reader's all-time low. Apple's AirPods Pro are $50 off their list price at $200, while the Apple Watch SE is a good value at $219. Beyond that, we're still seeing a handful of deals on Super Mario games for the Nintendo Switch, as well as discounts on Samsung storage gear and Logitech's MX Keys Mini keyboard, among others. Here are the best tech deals from this week that you can still get today.

Amazon Kindle Paperwhite

Amazon's Kindle Paperwhite is on sale for $100, which is $5 more than the e-reader's all-time low but still $30 or so less than its usual street price. We gave the "Signature Edition" of the Paperwhite a review score of 97 in late 2021; by comparison, this model has less storage (8GB instead of 32GB), no Qi wireless charging and a slightly less advanced front light. Those shouldn't be dealbreakers, though, as the standard Paperwhite still provides a sharp 6.8-inch display that's easy on the eyes, a lightweight and waterproof design with a USB-C port and access to the same mammoth e-book library.

There are excellent alternatives here: Kobo's Clara 2E, the top pick in our guide to the best e-readers, is a similarly capable device for those who'd rather not shop in Amazon's closed-off ecosystem, while Amazon's base Kindle offers a more affordable entry point into the Kindle library. Both of those models have six-inch displays, though. if you'd prefer a larger screen and don't mind buying your e-books from Amazon, the Paperwhite is still highly comfortable — and a good value at this price.

Samsung Evo Select

Samsung's Evo Select is a dependable way to add more storage space to a Nintendo Switch, Raspberry Pi, GoPro or any other gadget that supports microSD cards. The 256GB model is currently available for $19, which is a new low. This V30- and U3-rated card isn't the absolute fastest you can buy, but it's quick enough to run games and record 4K video with minimal issues, and it's backed by a 10-year warranty. Most importantly, it's affordable. For reference, this variant typically retails around $25.

Nintendo Switch game sale

A handful of deals from Nintendo's Mario Day sale last month are scheduled to end on Saturday, but recommended games like Super Mario 3D World + Bowser's Fury, Super Mario Odyssey, Mario Kart 8 Deluxe, Super Mario Maker 2, and New Super Mario Bros. U Deluxe are still down to $40 for now. While these are not massive discounts, they bring each game about $10-15 lower than usual. Nintendo is still fairly stingy when it comes to discounting first-party Switch games, so if this week's release of the The Super Mario Bros. Movie has you itching for more Mario at home, this is a decent chance to save.

Nintendo has a few other Switch game deals of note going on this week. The acclaimed FPS games Doom and Doom Eternal are down to all-time lows of $10 and $13, respectively, while a bundle that pairs the beloved RPGs Persona 3 Portable and Persona 4 Golden is $10 off at $30. The latter is the first discount we've seen for those Switch ports. Portal Companion Collection, which includes the classic first-person puzzler Portal and its co-op-friendly sequel Portal 2, is down to a low of $12 as well.

Logitech MX Keys Mini

Logitech's MX Keys Mini is a compact wireless keyboard we recommend in our guide to the best iPad accessories. It has a slim profile, but its backlit and well-spaced keys are more comfortable to type on than most portable keyboards we've tested. Typically priced around $100, the MX Keys Mini is currently available for $66 at Lenovo when you use the code EXTRA5 in your cart prior to checkout. This deal technically applies to the Business version of the device, which means it comes with a different USB receiver that isn't compatible with many older Logitech devices. However, the keyboard can still pair with and quickly swap between three separate devices over Bluetooth. 

Apple AirPods Pro

We've seen Apple's AirPods Pro fall to $200 multiple times in recent months, but this discount still comes within a dollar of the lowest price we've seen. Normally, the noise-cancelling earbuds go for around $225. We gave the second-gen AirPods Pro a score of 88 in our review last year, and they're currently the "best for iOS" pick in our guide to the best wireless earbuds. There are more well-rounded pairs out there with better battery life and mic performance, but Apple's in-ears still deliver impressive ANC and sound quality, and they're particularly easy to use with other Apple devices.

Samsung Galaxy S23

The unlocked, 128GB version of Samsung's Galaxy S23 is down to $700, which is a $100 discount for a phone that launched in February. The S23 isn't a top pick in our guide to the best smartphones, and it's not as strong of a value as Google's Pixel 7, but it's worth considering if you specifically want a smaller handset with flagship-level features. It's fast and well-built, and its 6.1-inch, 120Hz OLED display should be smooth and vibrant. The camera isn't top-tier in low-light settings but still far from poor overall, and Samsung is promising four years of OS upgrades, with an extra year of security updates. 

The S23 isn't the phone to buy for battery life, though, as its smaller size means there's less space for a battery that can last longer than a day. We gave the 6.6-inch Galaxy S23+ a review score of 86 earlier this year: Apart from the larger frame, that phone comes with twice as much storage by default, faster charging support and a bigger battery, but the two devices are otherwise similar. 

Fully Cora standing desk converter

The Fully Cora is a simple standing desk converter that we've previously recommended. It's meant more for a laptop and a handful of accessories than a full keyboard and monitor setup, but if you just want a way to sit less while working, it's a relatively unobtrusive, lightweight and easy-to-adjust tool for doing that. The device is currently available for $90 as part of a wider sale at Fully's online store. It's technically been at this price for a few weeks, but it's still half off Fully's MSRP. Just note that you may have to invest in a separate stand to keep your laptop at a more comfortable eye level. 

Apple Watch SE

The Apple Watch SE has dropped to $219, which is within $10 of the lowest price we've seen. This isn't the first time we've seen the smartwatch hit this price, but it's still $30 below Apple's MSRP. We gave the latest SE a review score of 89 last September, and we currently recommend it for first-time and budget-conscious wearable buyers in our guide to the best smartwatches. 

Compared to the pricier Apple Watch Series 8, the top pick in our guide, the SE lacks an always-on display mode, fast charging and premium features like a skin temperature sensor, ECG monitor and blood oxygen sensor. Its display is a smidge smaller, too. That said, it still provides most of the core Apple Watch feature set for way less money, with support for notifications, heart-rate monitoring and crash detection. It also uses the same processor as the Series 8, so it doesn't feel slow in everyday use. 

Samsung 980 Pro SSD with Heatsink

The 1TB model of Samsung's 980 Pro SSD with an integrated heatsink is on sale for $87, which is a new all-time low. On average, the device has run closer to $120 in recent months, though its price has steadily dipped over time. We recommend this speedy PCI Express 4.0 drive in our guide to the best SSDs for the PS5, as it meets Sony's strict requirements for upgrading that console's storage. 

It's best if you buy the 980 Pro for that specific purpose, though. If you simply want a new SSD for an aging PC and don't care about gaming, a less expensive PCIe 3.0 drive should be a better value. For that market, SK Hynix's Gold P31 is a well-regarded option that's currently down to $72 for a 1TB model.

Apple + Target gift card bundle

Here's a simple one: If you buy a $100 Apple gift card at Target, the retailer will throw in a $10 Target gift card for no extra cost. As a reminder, an Apple gift card can be used on purchases at the company's physical retail shops, the App Store and Apple services like iCloud and Apple Music. Target has run this promotion several times before, but if you plan on shopping at Apple and Target in the near future anyway, it's effectively a bit of free money. Target says the offer will end on April 8. 

Blue Yeti Nano

The grey model of the Blue Yeti Nano is on sale for $53 at Amazon. Outside of a very brief drop to $50 last year, that's the lowest price we've tracked. The Yeti Nano is a compact USB microphone we've recommended in the past. There are certainly clearer-sounding options for those looking to get into more professional recordings, but if you just want a mic upgrade for your work calls that's easy to set up and won't take up a ton of room on your desk, the Yeti Nano is a decent value when it's discounted to this extent. If space is less of a concern, note that the standard Yeti is down to $80; that mic is bigger but sounds better and offers more pickup patters to accommodate different types of recordings. 

Amazon Fire TV Stick 4K Max

Amazon's Fire TV Stick 4K Max is back down to $35, matching the lowest price we've tracked. The 4K media player has regularly bounced between this deal price and its MSRP of $55 in recent months, but for less than $40 it's a good value for those who want to add more streaming services to their TV. The device itself is reasonably fast and supports most of the major apps and HDR formats. (Compared to the standard Fire TV Stick 4K, the speed upgrade is enough to make the 4K Max a better buy.) It has voice search functionality built into its remote, which is convenient. For tinkerers, it's also easier to sideload unsupported apps here than it is with similarly priced streamers. 

The caveat is that the Fire TV UI tends to advertise Amazon's own content over shows and search results from other apps. That means the 4K Max will work best if you regularly use Amazon services like Alexa and Prime Video. If you aren't as beholden to Amazon, Roku's Streaming Stick 4K and Google's Chromecast are close alternatives that we recommend in our guide to the best streaming devices. The former has a simpler and more neutral interface, while the latter is generally more accurate at searching and better about personalizing its UI to your viewing habits.

Ninja DZ401 Foodi air fryer

Ninja's DZ401 Foodi is the "best dual-zone" pick in our guide to the best air fryers, offering two baskets that allow you to cook two foods in two different ways at the same time. Not everyone needs something this hefty, but if you often have to cook for a large family, it can be useful. The 10-quart model is down to $180, which is roughly $20 below its usual going rate. The device dropped as low as $130 during the holidays last year, but this discount matches the lowest price we've seen in 2023. 

Master & Dynamic MW75

A recommendation from our guide to the best wireless headphones, Master & Dynamic's MW75 is on sale for $419 with the checkout code GIVEGET30. Normally, this noise-cancelling pair goes for $599. Even at 30 percent off, it's hard to call the MW75 a great value, as its ANC can't really match less expensive alternatives like the Sony WH-1000XM5 or Bose QuietComfort 45. But the pair stands out for its decidedly upscale design, which uses a premium-feeling blend of leather, aluminum and tempered glass. It sounds nice as well, though some may prefer a bit less treble presence by default. 

Either way, we don't see the MW75 drop this low very often, so if you've got cash to burn and are particular about aesthetics, it's worth considering. The code above is applicable to various other Master & Dynamic headphones as well; the company says the sale will run through April 10.

The latest edition of Star Wars Celebration is underway and, along with some fresh details about shows coming to Disney+ over the next year or two, Lucasfilm revealed more info about what's ahead for the movie side of the franchise. It announced three Star Wars films, one of which will feature the return of Daisy Ridley as Rey.

That film will take place 15 years after the events of The Rise of Skywalker, the final movie in the Skywalker saga and the most recent Star Wars movie to hit the big screen. It will center around Rey forming a new Jedi Order. Academy Award winner Sharmeen Obaid-Chinoy (Ms. Marvel, Saving Face) will direct the film.

A movie from James Mangold (Logan, Indiana Jones and the Dial of Destiny) will delve into the origins of the Force and the Jedi. It will be set 25,000 years before anything else we've seen in the Star Wars universe to date, according to The Hollywood Reporter.

Meanwhile, Dave Filoni will finally get a shot at directing a live-action Star Wars movie. Filoni has been at the heart of the franchise for many years. He directed the 2008 animated film Star Wars: The Clone Wars and has been deeply involved with the recent spate of Disney+ shows, such as The Mandalorian, The Book of Boba Fett, Ahsoka and Skeleton Crew. Fittingly, the movie he's set to direct will tie the stories of those shows together and put a bow on them.

Disney and Lucasfilm haven't revealed release dates for any of these films. However, Disney's current slate includes holiday 2025 and 2027 dates for untitled Star Wars flicks.

After the last three Star Wars films (The Last Jedi, Solo and The Rise of Skywalker) didn't exactly receive wide acclaim, Disney and Lucasfilm walked back on their plans to release a movie every year. They have made several attempts to get other Star Wars films off the ground, including Patty Jenkins' Rogue Squadron, a trilogy from Game of Thrones creators David Benioff and D.B. Weiss, another trilogy from The Last Jedi director Rian Johnson and entries from Taika Waititi and Marvel Studios head honcho Kevin Feige.

All of those projects have either been canned or deprioritized, according to reports. Disney and Lucasfilm are evidently hoping these three freshly announced films will reignite Star Wars' success in movie theaters, even if we'll have to wait at least a couple of years to see the first of them.

AI Chatbots are relatively old by tech standards, but the newest crop — led by OpenAI's ChatGPT and Google's Bard — are vastly more capable than their ancestors, not always for positive reasons. The recent explosion in AI development has already created concerns around misinformation, disinformation, plagiarism and machine-generated malware. What problems might generative AI pose for the privacy of the average internet user? The answer, according to experts, is largely a matter of how these bots are trained and how much we plan to interact with them

In order to replicate human-like interactions, AI chatbots are trained on mass amounts of data, a significant portion of which is derived from repositories like Common Crawl. As the name suggests, Common Crawl has amassed years and petabytes worth of data simply from crawling and scraping the open web. “These models are training on large data sets of publicly available data on the internet,” Megha Srivastava, PhD student at Stanford's computer science department and former AI resident with Microsoft Research, said. Even though ChatGPT and Bard use what they call a "filtered" portion of Common Crawl's data, the sheer size of the model makes it "impossible for anyone to kind of look through the data and sanitize it,” according to Srivastava.

Either through your own carelessness or the poor security practices by a third-party could be in some far-flung corner of the internet right now. Even though it might be difficult to access for the average user, it's possible that information was scraped into a training set, and could be regurgitated by that chatbot down the line. And a bot spitting out someone's actual contact information is in no way a theoretical concern. Bloomberg columnist Dave Lee posted on Twitter that, when someone asked ChatGPT to chat on encrypted messaging platform Signal, it provided his exact phone number. This sort of interaction is likely an edge case, but the information these learning models have access to is still worth considering. "It’s unlikely that OpenAI would want to collect specific information like healthcare data and attribute it to individuals in order to train its models," David Hoelzer, a fellow at security organization the SANS Institute, told Engadget. “But could it inadvertently be in there? Absolutely.”

Open AI, the company behind ChatGPT, did not respond when we asked what measures it takes to protect data privacy, or how it handles personally identifiable information that may be scraped into its training sets. So we did the next best thing and asked ChatGPT itself. It told us that it is "programmed to follow ethical and legal standards that protect users’ privacy and personal information" and that it doesn't "have access to personal information unless it is provided to me." Google for its part told Engadget it programmed similar guardrails into Bard to prevent the sharing of personally identifiable information during conversations.

Helpfully, ChatGPT brought up the second major vector by which generative AI might pose a privacy risk: usage of the software itself — either via information shared directly in chatlogs or device and user information captured by the service during use. OpenAI’s privacy policy cites several categories of standard information it collects on users, which could be identifiable, and upon starting it up, ChatGPT does caution that conversations may be reviewed by its AI trainers to improve systems. 

Google's Bard, meanwhile, does not have a standalone privacy policy, instead uses the blanket privacy document shared by other Google products (and which happens to be tremendously broad.) Conversations with Bard don't have to be saved to the user's Google account, and users can delete the conversations via Google, the company told Engadget. “In order to build and sustain user trust, they're going to have to be very transparent around privacy policies and data protection procedures at the front end,” Rishi Jaitly, professor and distinguished humanities fellow at Virginia Tech, told Engadget.

Despite having a "clear conversations" action, pressing that does not actually delete your data, according to the service’s FAQ page, nor is OpenAI is able to delete specific prompts. While the company discourages users from sharing anything sensitive, seemingly the only way to remove personally identifying information provided to ChatGPT is to delete your account, which the company says will permanently remove all associated data.

Hoelzer told Engadget he’s not worried that ChatGPT is ingesting individual conversations in order to learn. But that conversation data is being stored somewhere, and so its security becomes a reasonable concern. Incidentally, ChatGPT was taken offline briefly in March because a programming error revealed information about users’ chat histories. It's unclear this early in their broad deployment if chat logs from these sorts of AI will become valuable targets for malicious actors.

For the foreseeable future, it's best to treat these sorts of chatbots with the same suspicion users should be treating any other tech product. “A user playing with these models should enter with expectation that any interaction they're having with the model," Srivastava told Engadget, "it's fair game for Open AI or any of these other companies to use for their benefit.”
