Channeling Trump, Chile’s new president launches work on border barrier

Chilean President Jose Antonio Kast wasted no time. Less than a week after his inauguration, Chile’s arch-conservative president on Monday began overseeing preparations to build a border barrier - part of his flagship campaign promise to block immigrants from crossing illegally. From Chile’s northern frontier area of Chacalluta, where legions of immigrants have slipped across the Peruvian border into one of the region’s most prosperous nations, Kast vowed to implement what he calls his “Border...

Ecovacs’ Deebot X8 and X9 Pro Omni robovacs are nearly 50 percent off

The Ecovacs Deebot X8 Pro Omni offer a range of smarts for a relatively affordable price. | Image: Ecovacs If you like the idea of spring cleaning but not the part where you actually have to clean, both the Ecovacs Deebot X8 Pro Omni and newer X9 Pro Omni have dropped to their lowest prices to date ahead of Amazon’s Big Spring Sale, which officially kicks off on March 25th. The X8 Pro Omni is available for $599 ($501 off) from Amazon, Best Buy, and Ecovacs, while the X9 Pro Omni is on sale for $679 ($621 off) at the same retailers (Amazon, Best Buy, Ecovacs). Deebot X8 Pro Omni Where to Buy: $1099.99 $599 at Amazon $1099.99 $599 at Ecovacs $1099.99 $599 at Best Buy Ecovacs Deebot X9 Pro Omni Where to Buy: $1299.99 $679 at Amazon $1299.99 $679 at Ecovacs $1299.99 $679 at Best Buy Both robot vacuums are packed with smart features designed to reduce the time you spend cleaning. Using lidar and a 3D camera for mapping, they can deftly navigate around furniture and baseboards, and even identify and avoid potential obstacles. The roller mop on both models also cleans itself while it works, and each robovac comes with a multifunction dock with a built-in water tank, allowing them to refill themselves and move dirty water into a separate waste tank. You can also use either the companion app or voice commands to control them thanks to their support for Matter, which lets you connect them to platforms like Alexa and Google Home. Both models are excellent cleaning devices, too, and each uses an extendable roller mop that can apply up to 4,000Pa of pressure and reach hard-to-clean areas (including corners). The biggest differences between the two models come down to how they handle suction and airflow while vacuuming. For instance, the last-gen X8 Pro Omni offers slightly more powerful suction at 18,000Pa, compared to 16,600Pa on the X9. The X9 Pro Omni, meanwhile, leverages Ecovacs’ Boosted Large-Airflow Suction Technology, which moves more air through the vacuu

How and where to buy refurbished tech online

In good news for our wallets and the environment at large, many electronic devices like phones and tablets last longer now than they once did. That means refurbished gadgets can have more life than ever before. There are no laws governing the terms, but refurbished or renewed devices tend to be a level above just plain “used.” At minimum, refurbished tech should have undergone cleaning and diagnostic testing. Some sellers also replace components like batteries and screens. Once ready for sale, these devices should operate as if they were new, with only minor scuffs indicating their history. Refurbished devices not only save you a bit of cash, they have a drastically lower carbon footprint since most environmental impact comes from manufacturing. It’s more efficient than recycling and helps keep e-waste out of landfills. But there are better places to shop refurbished tech than others. We’ve gathered /a few recommendations, along with our advice on what to look for when you start shopping for refurbished gear. What to consider when buying refurbished devices Refurbished vs used Refurbished is not the same as used. Used items tend to be sold “as-is,'' which means you’re simply inheriting whatever mileage and quirks a device had when the previous owner said goodbye to it. It’s true that most refurbished items were previously owned, and many are a result of the growing trend of trading in your old device when you upgrade. But others were hardly used at all and are one of the millions of returns generated each year. Either way, a properly refurbished item has undergone testing to verify that it works, along with cleaning, repairs and parts replacement as needed. Since there are no government regulations for renewed items, it’s up to the sellers to define what steps they take to ready a device for sale. And it’s up to the buyer to find out what those steps are before taking the plunge. The processes for refurbishing devices from Apple, Bose, Microsoft, Google Pixe

Crops irrigated with wastewater store drugs in their leaves

Scientists studying crops irrigated with treated wastewater discovered that trace pharmaceuticals often collect in plant leaves. Tomatoes, carrots, and lettuce absorbed medications such as antidepressants and seizure drugs during the experiment. However, the edible portions of tomatoes and carrots contained much lower levels than the leaves. The findings help researchers understand how crops process contaminants as wastewater reuse becomes more common.

That's the whole deal. - Can't edit yesterday. What's done is done. Keeps you from fussing over old entries instead of writing today's. - Year view with dots showing which days you actually wrote. It's a streak chart. Works better than it should. - No signup required. Opens right up, stores everything locally in your browser. Optional cloud sync if you want it - E2E encrypted with AES-GCM, zero-knowledge, the whole nine yards. Tech-wise: React, TypeScript, Vite, Zustand, IndexedDB. Supabase for optional sync. Deployed on Cloudflare. PWA-capable. The name means "one day" in Japanese (いちにち). The read-only past turned out to be the thing that actually made me stick with it. Can't waste time perfecting yesterday if yesterday won't let you in.

How to clean and organize your Mac

Inevitably, the more you use something — your Mac included — the more dirty and cluttered it’s likely to become. At that point, you can buy a new machine, but the more economical move is to make what you have already work better. To help your computer feel new, or at least a little cleaner and less chaotic, we put together this guide with techniques and useful apps that have helped us maintain a more organized computer. I’ve been using these tips since before I first published this guide in 2021, and they’ve helped keep my 2018 MacBook Air looking and running (almost) like brand new. How to clean your Mac’s screen and body While there are many products out there from manufacturers claiming their one does it best, my advice is to keep things simple. It’s also the one Apple recommends. To start, you will need some water in a spray bottle and a clean microfiber cloth. You can use regular water from the tap but I've found distilled water works best; it’s far less likely to leave residue behind on your Mac, particularly on the display. You can buy distilled water at a grocery store or make it yourself with some simple cookware. Either way, it’s more affordable than dedicated cleaning solutions. If you don’t already own any microfiber towels, Amazon sells affordable 24-packs you can get for about $10. One other product I would recommend is a Giottos Rocket Blower. I can’t say enough good things about this little tool. It will save you from buying expensive and wasteful cans of compressed air. As for the actual process of cleaning your Mac, remember to start with a clean cloth (that’s part of the reason we recommend buying them in bulk). You’ll save yourself time and frustration this way. Begin by turning off your computer and unplugging it. If you bought a Rocket Blower, use it now to remove any dust. If not, take a dry microfiber cloth and go over your computer. Take special care around the keys, particularly if you own an older Mac with a butterfly keyboard. N

Scientists just found a way to 3D print one of the hardest metals on Earth

Scientists have found a promising new way to manufacture one of industry’s toughest materials—tungsten carbide–cobalt—using advanced 3D printing. Normally, producing this ultra-hard material requires high-pressure processes that waste large amounts of expensive tungsten and cobalt. The new approach uses a hot-wire laser technique that softens the metals rather than fully melting them, allowing manufacturers to deposit the material only where it’s needed.

US to counter China’s critical minerals dominance with ‘game-changing’ innovations

Potential US innovation in recycling electronic waste, combined with refining and processing, will allow the US to leapfrog China in critical minerals, an official at the Department of Energy said on Monday amid Washington’s aggressive attempts to counter China’s dominance in the industry. Recycling metals, materials and magnets within the US is one of the fastest ways the country can impact the critical minerals supply chain, and entrepreneurs across the US are “pioneering” new techniques that...
