Ukrainian drone strikes have knocked out two of five data centers belonging to the Russian tech giant Yandex. The damage has left Yandex, known as “Russia’s Google” because it operates the country’s most popular search engine, struggling to maintain its AI chatbot and other online services.

The Ukrainian drones struck Yandex data centers in the Sasovo and Kaluga regions of Russia on October 8 and October 9, according to Reuters. Those actions came as a direct response to a Russian drone strike campaign targeting Ukraine’s data centers, which has disrupted mobile phone and Internet services for thousands of Ukrainians since late September.

“We continue to respond to Russia’s attacks on Ukraine, and we’re doing so with high precision,” said Ukrainian President Volodymyr Zelenskyy in a post on X. “Another data center was hit as well—our symmetrical response.”

The Museo de Historia de la Computación in Spain has unveiled a 1:1 scale visual replica of the famous Cray-1 supercomputer from 1976. Instead of sourcing expensive, cutting-edge tech to run the system, the creative team powered the project with 30 2012-era Mac Minis. Developed over 18 months, the project serves as a 50th-anniversary tribute to the Cray-1 and Apple's founding.

Mac Minis from over a decade ago might not seem like the obvious first choice for building a cluster supercomputer, but when networked together, the developers can orchestrate the 64 active processing cores into a combined 1.3 teraflops of performance in their most recent tests. The museum reportedly achieved 1.5 teraflops previously using all 70 available cores, prior to one node going offline. Benchmarks were obtained using a custom matrix-multiplication Python script. Five PCs are quad-core i7s, and the remaining 25 are dual-core i5 models. Except for two units from 2014, the rest of the array dates to 2012.

The replica is a valuable tool for museum-goers to understand the shifts in computer architecture since 1976. The original Cray-1 used vector processing, applying a single instruction to multiple data elements simultaneously, whereas the replica distributes work across independent processors in a parallel cluster. The peak theoretical performance of the original Cray-1 was approximately 160 megaflops. What was originally a purpose-built research machine has been re-created with consumer hardware that's vastly more capable than the machine that inspired it.

The Debian Linux project has opened a call for community artwork submissions ahead of the release of the upcoming Forky (Debian 14). If you think you've got the artistic chops, your art could appear on the boot screens, login prompts, and desktop wallpapers of millions of users. The submission deadline is November 26.

Continuing Debian's community-driven ethos, the artwork submission process mirrors that of previous releases. The artwork must feel distinctively "Debian," integrate cleanly without the need for core software patching, and remain visually appealing for the long term.

Elise Couper's "Ceratopsian" theme was chosen as the winning default for Debian 13 Trixie. For anyone who might not be up on the latest from the Toy Story franchise, the release names echo character names from the animated films. Trixie was a triceratops introduced in Toy Story 3, hence the "Ceratopsian" wink in the winning submission. It makes sense that the next version of Debian continues this trend with Forky, a character introduced in the franchise's fourth entry. The Debian team cautions against overly busy designs that may cause user fatigue, but if anyone can successfully incorporate Forky's googly eyes into the design somehow, know that you'd at least win the contest for my Debian desktop wallpaper.

Let's Encrypt is continuing a push toward tighter security by reducing free SSL/TLS certificate lifetimes from 90 days to 64 days, starting February 10, 2027. For administrators already implementing modern ACME clients that support ARI (ACME Renewal Information), the change should be seamless. For those still relying on hardcoded renewal schedules or manual processes, February will be the deadline to update before certificates start expiring unexpectedly.

Starting on October 14, Let's Encrypt will begin testing the 64-day certificates, and interested users can opt in to test their setups before production goes live.

Prior to Let's Encrypt's launch in early 2016, certificates were often issued for as long as one to three years. The service started with 90-day certificates to force renewal automation that didn't previously exist. Shorter certificate validity periods limited vulnerabilities from private key thefts and encouraged accelerated HTTPS adoption across the web.

For the last 15 years, you've been able to buy a Fire tablet from Amazon. Which Fire tablet? It doesn't matter—like Kindles, they have been pretty much the same year to year. The company's new tablet lineup is a big change, though. Amazon has dropped the Fire branding in favor of Alexa, and the new Alexa Tablets are now Google-certified Android devices.

Throughout the history of Fire Tablets, Amazon downplayed its use of Android. They ran Android apps from the company's Appstore platform, but there was no Google integration with "Fire OS." However, Amazon shut down its app store last year. The new Alexa Tablets run full-fledged Google-y versions of Android with the Play Store and all the apps you'd expect. This contrasts sharply with Amazon's Fire Sticks, which have abandoned Android for the custom Linux-based Vega OS.

The Alexa Tablet lineup consists of three devices, all redesigned with unibody aluminum housings. The Alexa Tablet 8 starts at $230, and the Tablet 11 jumps to $330. They run on the budget MediaTek 8189 processor, but that's still an upgrade from the last-gen Fire tablets. Both devices have 16:10 display ratios that are better for watching video, but the flagship tablet is a little different.

In its first live event in two years, Microsoft today announced its newest Surface laptop, outlined a host of changes coming to Windows 11, and shared a vision of how local-AI and agentic workflows could reshape personal computing for those in the dev community as well as home enthusiasts.

Surface Laptop Ultra

Originally teased in May 2026, the new Surface Laptop Ultra will be Microsoft's first offering to take advantage of the new Nvidia RTX Spark SoC (system on a chip). The device has a starting price of $2,599 and comes in various SoC and memory configurations, with either a 5120-core or 6144-core Blackwell GPU and up to 128GB of LPDDR5x unified memory. It will begin shipping on October 16 and is available for preorder now.

While the new Ultra is clearly focused on the developer crowd, graphical performance was highlighted during the presentation to show off just how capable the laptop can be. By leaning on unified memory allocation rather than the physical VRAM limits of a traditional GPU, the laptop can assign its resources to handle modern gaming tasks as well as local AI development and deployment. The new Gears of War: E-Day was shown running on the system, meaning that even without a traditional gaming GPU, AAA titles are on the table.

Drones sank two cargo ships and damaged a third in the exclusive economic zones of NATO member countries for the first time, killing at least two sailors. The attacks represent a notable escalation as Black Sea commercial shipping has increasingly come under attack during the Russian invasion of Ukraine, with Russia also being accused of carrying out “hybrid warfare” incidents across Europe.

The Togo-flagged cargo ship Alfa Watan sank, and the Palau-flagged cargo ship Able was set ablaze after being attacked by multiple sea and aerial drones about 80 miles (128 kilometers) off the coast of Bulgaria on October 6, according to the Associated Press. In an interview, Bulgarian Prime Minister Rumen Radev described the incidents as “an unacceptable attack in Bulgaria’s exclusive economic zone” and “a blatant violation of international law and maritime law.”

A Bulgarian ferry managed to evacuate the 18 crew members of the Able, with two severely injured mariners being flown to a hospital in the city of Varna.

After months of industry and customer speculation, Paramount Skydance has shed some light on the future of the HBO Max and Paramount+ streaming services.

Paramount Skydance completed its acquisition of Warner Bros. Discovery (WBD) today, ending a monthslong saga that began when Netflix last year announced its own plans to buy WBD. Netflix scrapped those plans in February. Skydance is the name of the company created from the $111 billion merger.

In an announcement today, Skydance said that all of the direct-to-consumer streaming services it owns, including the Discovery+ service that Discovery Inc. (which merged with WarnerMedia in 2022 to create WBD) launched in 2021, “will unify into a single service over time.”

Googlebooks are Google's latest attempt to carve out a piece of the premium laptop market, and tight integration with Android phones is a key part of that effort. Now that Googlebooks are available, we're learning of some frustrating limitations of that plan. For now, Googlebooks will only play nicely with your phone if you have a Pixel.

When Google announced the launch window for Googlebooks, it said the laptops were "engineered to work with your Android phone right out of the box." But as with many things Google, the truth is more convoluted. We have since learned that you need Android 17 for any of the nifty integrations to work. With a compatible Android 17 phone, you can seamlessly stream apps to your laptop, access files on your phone, mirror notifications, and continue where you left off in certain apps when switching from phone to laptop.

You might think that the latest Samsung phones, which shipped with Android 17, would be ready for this experience. You'd be wrong, though. Some early Googlebook adopters have complained that phones like the Z Fold 8 won't work with the laptops. While the devices appear to see each other, the phone doesn't stay connected. Google representatives have since confirmed that these "Better Together" features are not currently supported on even the latest Samsung phones. An update that brings support to Samsung phones will roll out in "the coming weeks."

A surge in Russian jet-powered drone strikes on Ukrainian data centers has increasingly disrupted mobile phone and Internet services for thousands of people. Now Ukraine President Volodymyr Zelenskyy and other government officials are warning of the need for more air defense capabilities, as such telecommunication outages could threaten Ukraine’s digital economy and undermine the country’s ongoing resistance to Russia’s invasion.

The Russian attacks on Ukrainian telecommunication infrastructure have focused on Ukraine’s capital of Kyiv since September 23, according to the nonprofit Reporters Without Borders. Ukraine’s digital transformation ministry reported that 100,000 households in the Kyiv region were temporarily experiencing Internet outages from those initial strikes—and Russia has only intensified its strike campaign against major Ukrainian data centers and mobile phone networks in recent weeks.

“Russian attacks on Ukraine’s telecommunication infrastructure are not new, with strikes and shelling previously damaging fiber optic lines, cell towers, and facilities belonging to mobile network companies,” said Tetiana Gaviuk, analyst for Europe at ACLED, in a post on October 1. “However, the recent concentrated attacks on Kyiv’s data centers and telecom networks stand out because multiple providers and facilities were hit within days, indicating Russia’s increased pressure on Ukraine’s digital infrastructure.”

The mechanical keyboard isn't always so mechanical anymore.

Over the past six years, keyboards with optical, Hall-effect, and other "contactless" switches have become increasingly common, often going for higher prices than traditional mechanical keyboards, which already command a premium over basic membrane boards. In return, they promise some theoretical advantages, particularly for gamers. In daily use, though, the differences can be pretty subtle.

So what exactly are you paying for? In this guide, we break down how the newest switches work, why contactless designs are becoming more popular, and where their advantages—and disadvantages—really matter.

This year, members of Seattle Mountain Rescue have been setting off into the wilds of the US Pacific Northwest wearing an unusual piece of kit.

They’ve been hiking into the wilderness with powered assistive devices attached to their hips and legs. Designed to increase lower-body strength when climbing or carrying heavy loads, these pieces of equipment are being tested to see if they can boost rescuers’ speed and endurance when it matters most—during searches for stranded people.

Devices like these are called human exoskeletons. They attach to parts of the body to create an external—or “exo”—mechanical structure. This powered frame enhances the wearer’s physical capabilities.

My family has spent four summers participating in demand response programs whereby utility companies pay customers to reduce energy use on the hottest summer days. Most summers have involved carefully precooling our New York City apartment before switching off the air conditioners and sweating it out during the designated demand response periods.

But this year, we kept our window air conditioners running throughout a heat dome event that drove daytime temperatures into the triple digits and made the nights oppressively hot. The difference was that we powered the air conditioners through two household batteries tucked away unobtrusively in the corners of our living room and bedroom.

We were among about 1,000 New York City households that took part in a free and growing program offered by the local startup Every Electric. The company’s proposition is simple: Get one or more batteries delivered to your home, plug the batteries into a standard wall electrical outlet, and then plug your window air conditioners into the batteries. Households can keep running air conditioners as usual during peak demand periods while also earning money through the local demand response program with the utility company Con Edison.

The era of generative AI has upended technology supply chains, and there is one ironclad rule in 2026: If it has memory or storage, it's getting more expensive. Even devices with years-old tech inside are still apparently subject to that unwritten rule. Nvidia has just announced that the Shield TV Pro is getting $100 more expensive, effective immediately.

The most recent version of the Shield streaming box debuted in 2019, running Android TV with AI upscaling and hardware decoding for almost any type of media. While it ran an aging Tegra X1+ processor, that was (and still is) fast for a TV media streamer. The device launched at $199.99, with a non-Pro variant at $149.99. The non-Pro Shield has since been discontinued, but the Shield TV Pro lives on at the new $299.99 price.

Nvidia has confirmed that you can blame AI for the higher Shield TV pricing. "Starting October 2, SHIELD Pro will be priced at $299. The cost of components, including memory, has increased substantially across the industry," a spokesperson told Ars.

What makes a display a Mini LED display?

It's a question that sounds like it should have a simple answer. But it's now at the center of a lawsuit between two of the biggest names in TVs, with TCL accusing its longtime competitor Samsung of falsely advertising budget LCD-LED TVs as Mini LED sets.

TCL may have a point. Samsung's M-series TVs, which range from $300 for a 43-inch model to $2,300 for a 100-inch model, do raise some legitimate questions about what should qualify as Mini LED. More broadly, though, the dispute highlights a problem for shoppers: Without agreed-upon standards for what "Mini LED" actually means, manufacturers have plenty of room to define the technology for themselves.

Micron and Samsung executives this week said the memory shortage will continue for at least the next couple of years.

Micron CEO Sanjay Mehrotra expects demand for the firm’s memory to exceed its available supply over that period, he told investors last night.

Micron no longer sells consumer RAM, and Mehrotra’s statements refer to Micron’s business-to-business sales of high-bandwidth memory (HBM) for AI and DRAM for servers. However, his comments also have implications for consumer devices. Manufacturing capacity is prioritizing memory for AI and servers, limiting the supply of memory manufactured for consumer devices.

Soon, Reddit won’t let people use Old.Reddit.com unless they have used the site while logged in within the previous six months.

In July, Reddit started requiring that users be logged in to access Old Reddit. This new requirement is an effort to reduce Reddit’s biggest source of scraping and automated traffic, the company says.

Today, the social media platform announced additional upcoming restrictions on Old Reddit. A Reddit post from an employee, known as "judy-funnie" on the platform, says that “in the next few months, we'll further limit access for logged-in users to only those who have used Old Reddit in the last six months (which covers the vast majority of all Old Reddit users).”

There was a call to boycott Disney last fall. The owner of the ABC network had taken Jimmy Kimmel Live! off the air over comments Kimmel made about responses to Charlie Kirk's murder, sending free speech proponents into a frenzy.

Those free speech proponents include me, who, as a reporter, has clear stakes in protecting that right. Although I was on board with halting support for a company I felt had acted wrongfully, truly boycotting Disney proved harder than I expected.

Disney's ubiquity

Canceling Disney+ was simple but threw a hefty wrench into my evening routine. I tend to end many weekdays laughing at comforting sitcom reruns and adult animation. I usually associate Disney with princesses, kids' movies, and, more recently, comic heroes. But Disney also owns Hulu, which exclusively streamed many of my favorite shows for unwinding at the time, like American Dad, Futurama, Living Single, Fresh Off the Boat, and It’s Always Sunny in Philadelphia.

Discord has announced tools aimed at expanding the number and types of companies that advertise on the platform.

This week, the social media firm announced Discord Ads Manager, an ad campaign management platform that lets companies manage ads shown on Discord in one place. The tool can be used to perform forecasting, build “a campaign with objective-based bidding,” and monitor an ad campaign’s performance, according to the announcement.

“Self-service access extends Discord advertising to smaller studios and marketers that previously needed a direct sales relationship to run campaigns, opening the platform to advertisers, regardless of their budget,” Discord said.
