Submission + - Wi-Fi Routers Can Scan Your Body to Identify Exactly Who You Are (futurism.com) 1

JoeyRox writes: New research out of Germany’s Karlsruhe Institute of Technology found that the types of Wi-Fi routers we all have in our homes come with a major privacy vulnerability that can be used to identify any human body that comes within their range.

The study, flagged by Gizmodo, used machine learning systems to identify individuals with an accuracy rate of 99.5 percent. To do so, the researchers exploited a vulnerability in a process known as beamforming feedback information (BFI), which was introduced to allow routers to focus Wi-Fi signals on connected devices, as opposed to the older approach, which is to blanket an entire area in coverage.

While BFI is great for network connectivity, it has a major downsides for privacy. For starters, devices connected to a router using beamforming need to send constant feedback in order to be found. As routers send out and receive network feedback, the signal is inevitably impacted by real world factors like pets, walls, and people.

Making matters worse is the fact that this data is basically wide open for anyone to grab — not only is that feedback data unencrypted, it can also be accessed without ever connecting directly to the router.

Submission + - I found a second vote.gov -- and it's registered to the White House

As_I_Please writes: The Drey Dossier reports that the National Design Studio, an office created by executive order and which reports only to the White House, has been building copies of federal agency websites like vote.gov, passports.gov, login.gov and others.

What [the National Design Studio] is doing is taking the parts of the federal government that touch you directly, your prescription, your voter registration, your passport, your federal login, out of the agencies that legally own them and rebuilding them on White House infrastructure. Vote.gov belongs to the Election Assistance Commission, and the studio built a copy. Passports belong to the State Department, and the studio is building a replacement this week. Login.gov belonged to GSA, and the studio’s guy runs it now.

Trump has said publicly that this infrastructure is for other presidents, and he is right about that. It is the one thing in this story I take him at his word on. The infrastructure outlasts him. Whoever wins in 2028 inherits the websites, the vendors, the data, and the hardware, sealed and waiting.

Jensen Huang to college grads: "Run. Don't walk" toward AI

https://www.axios.com/2026/05/...

Nvidia founder and CEO Jensen Huang told graduates at Carnegie Mellon University in Pittsburgh yesterday that demand for AI infrastructure is creating a "once-in-a-generation opportunity to reindustrialize America and restore the nation's capacity to build."

Why it matters: With many college grads fearing AI could obliterate their career dreams, Huang pointed to boundless opportunity as a "new industry is being born. A new era of science and discovery is beginning ... I cannot imagine a more exciting time to begin your life's work."

Nvidia, which makes AI chips, is the world's most valuable company. Huang told 5,800 recipients of undergraduate and graduate degrees that the AI buildout will require plumbers, electricians, ironworkers, and builders for chip factories, data centers and advanced manufacturing facilities.

"No generation has entered the world with more powerful tools â" or greater opportunities â" than you," he said. "We are all standing at the same starting line. This is your moment to help shape what comes next. So run. Don't walk."

"Every major technological revolution in history created fear alongside opportunity," Huang added. "When society engages technology openly, responsibly, and optimistically, we expand human potential far more than we diminish it."

Submission + - AI finds signs of pancreatic cancer before tumors develop (nbcnews.com)

fjo3 writes: An AI model developed at the Mayo Clinic in Rochester, Minnesota, detected abnormalities on patients’ CT scans up to three years before they were diagnosed with pancreatic cancer, according to research published this week in the journal Gut.

The scientists behind the model, which is now being evaluated in a clinical trial, trained it by feeding it CT scans from patients who had been screened for other medical conditions then were later diagnosed with pancreatic cancer. The team then had radiologists review the scans and compared their ability to find early signs of cancer to that of the AI model. The model was found to be three times better at identifying the early signs.

Submission + - Copy Fail exploit lets 732 bytes hijack Linux systems and quietly grab root (nerds.xyz)

BrianFagioli writes: A newly disclosed Linux kernel vulnerability called Copy Fail (CVE-2026-31431) allows an unprivileged user to gain root access using a tiny 732-byte script, and it works with unsettling consistency across major distributions. Unlike older exploits that relied on race conditions or fragile timing, this one is a straight-line logic flaw in the kernelâ(TM)s crypto subsystem. It abuses AF_ALG sockets and splice to overwrite a few bytes in the page cache of a target file, such as /usr/bin/su. Because the kernel executes from the page cache, not directly from disk, the attacker can inject code into a setuid binary in memory and immediately escalate privileges.

What makes this especially concerning is how quiet it is. The file on disk remains unchanged, so standard integrity checks see nothing wrong, while the in-memory version has already been tampered with. The same primitive can also cross container boundaries since the page cache is shared, raising the stakes for multi-tenant environments and Kubernetes nodes. The underlying issue traces back to an in-place optimization added years ago, now being rolled back as part of the fix. Until patched kernels are widely deployed, this is one of those bugs that feels less like a theoretical risk and more like a practical, reliable path to full system compromise.

Comment One Solid Reason for Homework (Score 1) 192

I haven't been in the classroom since close to the year 2000, so I don't remember the study names. What I do remember is that there were studies, plural - studies, that showed that when you learn how to do a new task or learn new information, that using that information or practicing the task within 24 hours increases the chance of it being remembered by a large percentage. That's over 25 years ago for me, and I'm not going to claim it's at a certain percentage, but I know it was WELL over 50%. So if you learn a new process in Algebra, or a new move in ballroom dance, and you don't practice it within 24 hours, you have a lower chance of remembering it. But it was at least over a 50% increase in your chance of remembering it IF you reinforced it by going through it within 24 hours.

I preferred to use homework as practice - not as learning new material (although that might help if it includes reading for the next day's class). I also worked in psych treatment, which meant I taught more than one subject - I had the odd mix of science and math plus English (lit and grammar). So I'd assign reading overnight that gave us more chance for discussion (discussion, not lecture!), and the math I assigned was to use what we had learned in class. For science, I'd actually prefer to assign reading for what we had done that day, compared to what we would do the next day. That way students found the reading easier, it went faster, and they'd bring in a few questions the next day that we could review (before moving on to new material).

When I grew up, I was forced to go to a prep school where we had 3 or more hours of homework a night, plus we were required to stay for some form of athletics, so I rarely got home before 6 PM. With that in mind, I was selective about homework. For the time I was teaching in public schools (as opposed to my time teaching in treatment), the dept. heads and supervisors jumped on me for not giving enough homework or for assigning science material we had reviewed in class - pretty much everything about my homework system offended the dept heads or supervisors.

Submission + - Longevity Escape Velocity Achieved Within Three Years (popularmechanics.com)

frdmfghtr writes: Popular Mechanics has a story about the rate at which lifespans are being extended by medical technology will surpass actual aging.

From the article:
"There's a controversial idea floating around the futurist community of "longevity escape velocity." It sounds super sci-fi, but it's basi-
cally the idea that as our life extension technology gets better, our life expectancy could increase by more than we age over a set period of time. For example, as medical innovations continue to move forward, we would still age a year over the span of a year. But our life expectancy would go up by, say, a year and two months, meaning we would functionally get two months of life back."

Submission + - US government ramps up mass surveillance (theconversation.com) 2

sinij writes:

People have little choice when buying devices, using apps or opening accounts but to agree to lengthy terms that include consent for companies to collect and sell their personal data. This “consent” allows their data to end up in the largely unregulated commercial data market. The government claims it can lawfully purchase this data from data brokers. But in buying your data in bulk on the commercial market, the government is circumventing the Constitution, Supreme Court decisions and federal laws designed to protect your privacy from unwarranted government overreach.

Still nothing to hide?
