Russia wages “relentless and destructive” cyberattacks to bolster Ukraine invasion

On March 1, Russian forces invading Ukraine took out a TV tower in Kyiv after the Kremlin declared its intention to destroy “disinformation” in the neighboring country. That public act of kinetic destruction accompanied a much more hidden but no less damaging action: targeting a prominent Ukrainian broadcaster with malware to render its computers inoperable.

The dual action is one of many examples of the “hybrid war” Russia has waged against Ukraine since before the invasion began, according to a report published Wednesday by Microsoft. Shortly before the invasion, the company said, hackers in six groups aligned with the Kremlin have launched no fewer than 237 operations in concert with the physical attacks on the battlefield. Almost 40 of them targeting hundreds of systems used wiper malware, which deletes essential files stored on hard drives so the machines can’t boot.

“As today’s report details, Russia’s use of cyberattacks appears to be strongly correlated and sometimes directly timed with its kinetic military operations targeting services and institutions crucial for civilians,” Tom Burt, Microsoft corporate vice president for customer security, wrote. He said the “relentless and destructive Russian cyberattacks” were particularly concerning because many of them targeted critical infrastructure that could have cascading negative effects on the country.

Apple launches self-service repair program for iPhone users in the US

First announced in November, Apple is now selling and renting parts to customers who want to repair their iPhones.

In a blog post, Apple describes the program, which closely matches what was previously announced. You can now visit an online “Self Service Repair Store” to read repair manuals and order tools and ports. The store is only available in the United States for now, but it’s coming to other countries later this year. The first additional countries will be in Europe, Apple says.

The store offers more than 200 parts and tools. Apple says the parts are the same as those used in Apple’s network of authorized repair providers.

Atomically thin electronics built using chemical reactions

There have been a variety of demonstrations of the capabilities that atomically thin materials can bring to electronics—extremely small size, excellent performance, and some distinctive properties. But almost all of these demonstrations required that the electronics being tested were essentially assembled by hand. Materials like graphene are often placed on a surface at random, and then the wiring needed for it to function is built around that location. It’s not exactly a recipe for mass production.

To the extent there’s been some progress, it’s been limited. One of the more recent efforts involved using graphene and molybdenum disulfide to make the transistor with the smallest gate length. In this case, the two atomically thin materials had to be placed carefully, but not exactly. Any excess material was etched away, and a key feature was made by cutting through the graphene sheet.

This week saw a somewhat different take on constructing these minuscule devices: chemistry. A research team linked up the two materials used in the earlier study, graphene and molybdenum disulfide, using a single bridging molecule that could react with each of them. The chemistry of the bridging molecule also influenced the behavior of a device made using this approach.

How to Center a Div with CSS

There are a few common coding problems you might encounter when you start practicing what you’ve learned by building projects. One common problem you’ll face as a web developer is how to place an element at the center of a page or within an element acting as its container. It’s

How to Send Large Video Files – Share a Big File with Email

Sending large files through email can be quite challenging. This is because each email client has a size limit for file sharing. Gmail and Yahoo limit file size to 25MB, while outlook and iCloud limit files to 20MB. So, if you decide to send, for example, a video file larger

Today’s best deals: Apple’s 16-inch MacBook Pro, Google Nest devices, and more

Time for another Dealmaster! Our latest roundup of the best tech deals from around the web includes the lowest price we’ve tracked on the 2021 16-inch M1 MacBook Pro. The 2021 MacBook Pro brought back a number of sorely missed ports and added Face ID while delivering the best performance money can buy (provided you have a lot of money), according to our Senior Reviews Editor Samuel Axon. It’s a return to form for MacBook-loving creatives, even if the physical form is larger than the last generation.

We also have some deals on Google Nest devices. Both the popular Nest Learning Thermostat and the more wallet-friendly Nest Thermostat are on sale, for instance, with the former down to $199 and the latter available for $100 at various retailers. While neither deal brings the absolute lowest price we’ve tracked, both are below their typical prices online and well under Google’s MSRPs of $250 and $130, respectively.

In any event, both devices remain commendable options for those aiming to adopt a smart thermostat, either to cut down on energy usage or take greater control over their home’s heating and cooling. The higher-end Nest still looks sharp, installs relatively easily, and works with a variety of smart home devices and platforms. It can still “learn” your usual heating and cooling preferences, then automatically schedules its future adjustments accordingly, (mostly) staying out of your way over the course of a day. The more affordable Nest Thermostat lacks that auto-scheduling feature (though you can still enter a schedule manually), has a cheaper plastic frame, and doesn’t support Google’s remote temperature-balancing sensors. But it still looks nice and has otherwise similar features—including tools like HVAC monitoring and voice commands via Alexa or the Google Assistant—for less money.

Belkin to release cable-free wireless charging tech this year

For all the “wireless charging” tech available, there are still a lot of power cables slithering throughout homes. Even wireless charging stations require a cord. That’s what makes the impending arrival of over-the-air wireless charging, which sends power without a cable or pad, exciting. Thus far, the technology has been limited to commercial uses in the US, but Belkin is expected to release a true wireless charging product for individuals this year.

California-headquartered Belkin offers a variety of consumer tech, including wireless charging stands supporting Apple MagSafe and speakers. On Wednesday, it announced a partnership with Wi-Charge to create consumer products that support over-the-air charging. The Israel-based company says its technology uses infrared beams to send up to 1 W of power to devices within a range of up to 40 feet.

The announcement didn’t specify what product Belkin would incorporate Wi-Charge tech, but Ori Mor, chief business officer and co-founder of Wi-Charge, told TechCrunch it would be “a center-stage consumer product” released sometime this year. Mor pointed to Belkin’s businesses in charging accessories and smart home and powerline products as areas that would benefit from over-the-air charging.
