Let's Encrypt cuts certificate lifetimes to 64 days starting February 2027

fivenewscrypto    octobre 09, 2026   

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.

Amazon's new Alexa Tablets drop the Fire branding but are more Android than ever

Amazon's new Alexa Tablets drop the Fire branding but are more Android than ever

fivenewscrypto    octobre 09, 2026   

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.

Microsoft event debuts new AI-friendly hardware and Windows changes

Microsoft event debuts new AI-friendly hardware and Windows changes

fivenewscrypto    octobre 09, 2026   

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.

“Software is over”: Bold AI developer takes aim at Adobe with open source clones

“Software is over”: Bold AI developer takes aim at Adobe with open source clones

fivenewscrypto    octobre 09, 2026   

For a while, those hoping to avoid the difficulty and expense of dealing with Adobe's Creative Suite have been able to use several free and/or open source alternatives that replicate some or all of those capabilities. Now, one developer is using AI-powered reverse engineering to mimic the look, feel, and functionality of Adobe's well-known software with what he hopes will soon be perfect fidelity.

Artcraft got its start last year as a "controllable AI for artists" that allows for precise post-generation editing of AI-crafted images and videos. Over the weekend, though, the brand debuted its pivot to a suite of seven open source apps recreating the user interface and tools found in Adobe's Photoshop, Illustrator, Premiere, Lightroom, After Effects, InDesign, and Acrobat Pro.

In announcing those new apps on Reddit earlier this week, software developer Brandon Thomas said he used Anthropic's Claude Opus 5.5 to create "clean-room replacements" for Adobe's closed source software in Rust (with WebAssembly versions available for use in a browser). And while commenters on Hacker News and elsewhere have taken pains to point out the new software's many current shortcomings, Thomas makes the grandiose promise that the current "super early alpha" state will soon lead to something just as functional as anything Adobe has ever put out.

PA measles outbreak tops 1,000 cases, largest since disease was eliminated

PA measles outbreak tops 1,000 cases, largest since disease was eliminated

fivenewscrypto    octobre 09, 2026   

Pennsylvania's explosive measles outbreak is now the largest the US has seen since the highly infectious virus was declared eliminated in 2000. With well over 1,000 cases, it's the largest on record since 1991.

Pennsylvania's health officials reported 1,078 measles cases in all of 2026 as of this afternoon. That includes 12 cases in January and March, with the remaining 1,066 cases since April, when the current outbreak began. The tally includes 145 cases recorded in the last seven days and 74 identified since the previous update on Monday. Health officials noted that 40 of the 74 cases added today were from more than two weeks ago and are just now being recorded.

Among the cases, there have been 207 hospitalizations and five deaths—a newborn, a 6-week-old, an 18-year-old, a 20-year-old, and a 40-year-old. All of the deaths occurred during the current outbreak in people who were unvaccinated; the two infants were too young to have been vaccinated.

TP-Link problems in US grow amid FCC router ban and four state lawsuits

TP-Link problems in US grow amid FCC router ban and four state lawsuits

fivenewscrypto    octobre 08, 2026   

TP-Link is facing more legal troubles in the US as Florida and three other states filed lawsuits alleging that it lied to consumers about its connections to China and the risks of its routers being exploited by Chinese state hackers.

The lawsuits were filed yesterday, about six months after the Federal Communications Commission announced a sweeping ban on consumer-grade routers produced wholly or partly outside of the US. Numerous router makers have obtained exemptions to the ban, but the Trump administration so far has not granted one to TP-Link.

Router makers that received exemptions include Netgear, Asus, Adtran, Amazon and its Eero subsidiary, Calix, Nokia, SpaceX's Starlink division, and others. For now, TP-Link is unable to sell its latest Wi-Fi 8 routers in the US, though models approved before the ban can still be sold.

Chemistry Nobel goes to reactions like those that gave life a hand

Chemistry Nobel goes to reactions like those that gave life a hand

fivenewscrypto    octobre 08, 2026   

Life is remarkably selective. Life relies on many molecules with what is termed "handedness"—they're chemically identical but are mirror images of each other. Most chemical reactions will make a 50-50 mix of the left- and right-handed forms of a chemical, but life uses only one of them. In fact, because of the differences between left- and right-handed chemicals, most of the key enzymes used by organisms will fail to work if they're presented with chemicals that have the wrong handedness.

That poses a bit of a challenge for origin-of-life research, as we're forced to explain how a world that may have started with an even mix of left- and right-handed chemicals produced organisms that only used one of them.

Today's Nobel Prize in Chemistry goes to two individuals, Henri Kagan and Kenso Soai, who discovered chemical reactions could be biased, producing large excesses of one of the two forms of a chemical.
